Description

The latch positioning and locking device

Technical field

The present invention relates to a kind of positioning and locking device of the thing that is locked, particularly a kind ofly carry out fast spacing positioning and locking device, belong to the hardware fitting technical field through rotatable handle.

Background technique

Fast quick-detach or installed device need be locked through spacing locking device, to guarantee the safe handling of equipment in motion state.The equipment that loads on the mobile platform of van or vehicle-mounted shelter and so on needs reliable locking when vehicle driving, stop when using, and needs quick release, uses outward so that the dismounting mobile unit is transferred to car.Existing mobile unit positioning and locking device adopts straight tube structure; Half-twist behind the pulling handle; Realize locking or release, the shortcoming of this device is an inconvenient operation, and requiring the user to have certain arm strength could lock or release equipment by level pulling handle; Also need adjust handle angle equipment is firmly locked, waste time and energy during use.

Summary of the invention

The purpose of this invention is to provide a kind of simple in structure, easy for installation, use latch positioning and locking device laborsaving especially, that can open fast or lock.

The present invention is achieved through following technological scheme:

A kind of latch positioning and locking device comprises pedestal, latch, handle, spring and positioning key, and said pedestal is T-shaped, the upper plate that comprise base body, extends on the side direction both sides from the base body, the pedestal hole that connects before and after base body is provided with; Latch and pedestal hole are slidingly matched, and latch front end telescopically passes in and out the equipment that is locked, and the latch rear end is provided with axial counterbore, and said axial counterbore rear end central authorities are provided with the handle groove of up/down perforation; Positioning key in the form of sheets, between spring and handle, the positioning key front end is inlaid on the pedestal rear end; Spring is positioned at axial counterbore, and spring rear end is resisted against on the positioning key front end; The handle front end embeds in the handle groove of latch rear end, is resisted against on the positioning key rear end, and the handle front end is hinged through lateral pin and latch rear end.

The object of the invention can also further realize through following technical measures.

Aforesaid latch positioning and locking device, wherein said latch front end is a taper type.

Aforesaid latch positioning and locking device, wherein said handle are flake handle, and handle one end is a cam structure, and the other end is a circle structure, and when latch stretched out locking, the plane of handle front end was resisted against on the positioning key rear end.

Aforesaid latch positioning and locking device, wherein less than the center, lateral pin hole of the handle distance A to the cam profile peak, cam is stretched journey A-L and is the latch stroke to the distance L on handle front end plane at the center, lateral pin hole of handle.

Compact structure of the present invention, simple, the simple operation of technology; Cost is low, it is little, safe and reliable to take up room, applicability is wide, use time saving and energy saving and possess quick positioning and locking ability; The present invention utilizes the mild increase of cam profile lift to promote moving of latch; As long as handle is rotated 90 °, just can pull out or return lateral pin, realize release or locking to the thing that is locked; Very easy to use, be widely used in the quick locking and the quick release of the plurality of devices such as vehicle-mounted hanging ladder, cable disc, portable power generation unit in van or the vehicle-mounted shelter.

Advantage of the present invention and characteristics will illustrate through the non-limitative illustration of following preferred embodiment and explain that these embodiments only provide with reference to accompanying drawing as an example.

Description of drawings

Fig. 1 is the structural representation of locking state of the present invention;

Fig. 2 is the right elevation of Fig. 1;

Fig. 3 is the structural representation of released state of the present invention.

Embodiment

Below in conjunction with accompanying drawing and embodiment the present invention is described further.

As depicted in figs. 1 and 2; The present invention includes pedestal 1, latch 2, handle 3, positioning key 4 and spring 5; Pedestal 1 is T-shaped, the upper plate 12 that comprise base body 11, extends on the side direction both sides from the base body 11, and upper plate 12 two ends are provided with tapped hole 13; Pedestal 1 is fixed on the mobile platform of van or vehicle-mounted shelter and so on through fastening screw trip bolt 14, the pedestal 1 of present embodiment is fixed on the angle steel 8 of van or vehicle-mounted shelter through 2 fastening screw trip bolts 14.The pedestal hole 111 that connects before and after base body 11 is provided with; Latch 2 is slidingly matched with pedestal hole 111; Latch 2 front ends are taper type, and telescopically passes in and out in the equipment that is locked, and the taper type structure is convenient to back, latch 2 front end centerings location and is got in the positioning hole of the equipment that is locked.

Latch 2 rear ends are provided with axial counterbore 21; Axially counterbore 21 rear end central authorities are provided with the handle groove 22 of up/down perforation, positioning key 4 in the form of sheets, between spring 5 and handle 3; Positioning key 4 front ends are inlaid in the locating slot of pedestal 1 rear end; Spring 5 is positioned at axial counterbore 21, and spring 5 front ends are resisted against on counterbore 21 bottoms of latch 2, and the rear end is resisted against on positioning key 4 front ends.Handle 3 front ends embed in the handle groove 22 of latch 2 rear ends; Be resisted against on positioning key 4 rear ends; Handle 3 front ends are hinged with latch 2 rear ends through the lateral pin 6 that passes across latch 2 rear ends and handle 3 rear ends, and lateral pin 6 two ends are spacing through the pin 7 that passes across lateral pin 6 respectively, prevent that it from coming off.

Handle 3 one ends are cam structure 31, and the other end is a circle structure 32, are convenient to point catch on the rotating operation that annulus 32 carries out handle 3.When latch 2 stretched out locking, the plane 33 of handle 3 front ends was resisted against on positioning key 4 rear ends.The distance A of cam profile peak is arrived at the center, lateral pin hole of handle 3 less than 61 centers, lateral pin hole of handle to the distance L on handle front end plane 33; Cam is stretched journey A-L and is the latch stroke, can confirm that required cam stretches the concrete data of journey A-L according to the concrete structure of the thing that is locked.

As shown in Figure 3, when the equipment of being locked needs release, catch on annulus 32 with finger; Handle 3 is turned to the position shown in double dot dash line among Fig. 3 counterclockwise gently around 61 centers, lateral pin hole; Handle 3 overcomes the elastic force of spring 5, is resisted against on positioning key 4 rear ends from the preceding Transverse plane 33 of original handle 3, turns to the cam profile peak and is resisted against on positioning key 4 rear ends; The elastic force that produced when lateral pin 6 has overcome spring 5 pressurizeds this moment, pulling latch 2 move to right and break away from the equipment that is locked.

When the equipment of being locked need be locked; Catch on annulus 32 with finger; Handle 3 is rotated around center, lateral pin hole clockwise gently; Latch 2 moves to left under the elastic force effect that spring 5 resets automatically, is resisted against on positioning key 4 rear ends until the preceding Transverse plane 33 of handle 3, and latch 2 injected rapidly in the positioning hole of the equipment that is locked and accomplished locking this moment.

Elastic force effect owing to spring 4 resets makes that the rotation of handle 3 of the present invention is very flexible, and latch 2 withdraws from the positioning hole completion release of the equipment of being locked gently, or the quick automatically positioning hole completion of injecting the equipment that is locked is locked all very reliable.

Except that the foregoing description, the present invention can also have other mode of executions, and all employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop in the protection domain of requirement of the present invention.
