Quick release systems

QUICKLOC® - Quick releases Innovative joint solutions play an important role in today’s modern industry, which is mainly characterised by the aim to strive for economic efficiency and productivity. High-maintenance components require easy accessibility, for example, paneling parts call for a design-oriented function element and housings of protective devices for captive fasteners. For all these and many more requirements in fastening technology, Bollhoff offers quick releases of high performance reliability under the name of QUICKLOC®. QUICKLOC® quick releases are versatile and therefore employed...

QUICKLOC® Light - Advantages Our QUICKLOC® Light clamping, rotation and pressure locks create repeatedly releasable joints. Easy to fit and even easier to operate - the right quick-release system also allows repeated opening and closing. QUICKLOC® is the perfect solution for components that are frequently used or serviced. Advantages QUICKLOC® Light ■ Quarter-turn assembly and disassembly ■ Counterclockwise and clockwise opening ■ Easy closing by turning or axial pressure ■ Quick release locked against falling out (as required by Machinery Directive 2006/42/EC)

QUICKLOC® Light – Installation process QUICKLOC® Light – three-piece system. Insertion of the locking bolt into the bore hole; optional locking with a retaining washer. Clipping the receptacle into a square or rectangular hole. To lock the joint, the locking bolt is screwed into the receptacle under light pressure and locks in due to the fittingly shaped curve geometry. Thanks to its geometry, it is then held in place without clearance. When the joint is opened by a clockwise or counterclockwise quarter turn, the elastic part of the receptacle is stretched and the locking bolt released. Watch...

QUICKLOC® Light – Function Overall function QUICKLOC® Light quick releases are based on three component parts: Lock top (bolt) Lock bottom (receptacle) Retaining washer (locking device) Lock bottom – receptacle The first step is to choose the receptacle because it affects the grip length. Grip length The following parameters are added to determine the grip length: grip lengthmin = over height* + retaining washer (thickness)** + 0.7 mm + possible cover spacing Grip lengths vary depending on the receptacle. A + 1.5 mm tolerance can be added to the indicated nominal dimension. Within this tolerance,...

QUICKLOC® Light - DesignQUICKLOC® Light - Standard design Different designs of QUICKLOC® Light locking bolts and lock bottoms are always on stock or can be produced with short lead times. Please see pages 8 to 9 for the design range. Please do not hesitate to ask. - Closing by application of pressure or turning ■ Size and direction of required tolerances ■ Size and direction of required forces The individual elements of the lock are systematically combined to allow perfect suitability for the intended function.

QUICKLOC® Light - DesignConvincing variety illustrated with the example of the locking bolt - head shapes We group head shapes according to the mode of operation: ■ Hand-operated ■ Tool-operated (e.g. slot, internal serration) Locking bolts - closing curves Thanks to different curve geometries on the locking bolt, the joint can be perfectly adapted to the intended mode of operation. Description of available closing curves and functions: ■ Closing by pressure on bolt or cover ■ Blade for easier fit into receptacle ■ Small space requirement in “depth” ■ Open/close counterclockwise and clockwise...

QUICKLOC® Light – Design Lock bottoms – receptacles Receptacles are available for different material thicknesses. They can be delivered with square or rectangular shape. There are the following advantages: Square design: For hand-operated locking bolts, the orientation can be turned 90° when the joint is closed. Rectangular design: The hand-operated locking bolt can only be installed in one position. For a receptacle with slotted hole, longitudinal tolerance compensation can be realised. Since the shank length of the locking bolt depends on the receptacle, the receptacle must be chosen first.

QUICKLOC® Solid - Advantages QUICKLOC® Solid is widely used where rapid assembly and disassembly is required. Simplicity of use makes it ideal when service requirements involve the removal and re-installation of panels and guards. Less than half a rotational turn releases and reengages the fastener. Advantages QUICKLOC® Solid ■ Half-turn assembly and disassembly ■ Easy closing by turning ■ Positive secure locking ■ Consistent clamp force ■ Stud can be captivated to the panel ■ Robust full-metal solution ■ Quick release locked against falling out ■ Compensates for panel tolerance

QUICKLOC® Solid – Installation process QUICKLOC® Solid – three-piece system. The receptacle is slipped on to the component to be fastened. Insertion of the stud into the bore hole and locking with a retainer. Insertion of the stud into the receptacle. Half a turn is necessary for locking of the joint. Turning it back will release the joint. Watch an online video about the functional principle of QUICKLOC® Solid. https://www.boellhoff.com/videos/quickloc-solid
