A kind of latch positioning and locking device, comprises pedestal, latch, handle, spring and positioning key, and described pedestal is T-shaped, the upper plate that comprise base body, extends on side direction both sides from base body, the pedestal hole connecting before and after base body is provided with; Latch and pedestal hole are slidably matched, and latch front end telescopically passes in and out the equipment that is locked, and latch rear end is provided with axial counterbore, and described axial counterbore rear end central authorities are provided with the handle groove of up/down perforation; In the form of sheets, between spring and handle, positioning key front end is inlaid on pedestal rear end positioning key; Spring is positioned at axial counterbore, and spring rear end is resisted against on positioning key front end; Handle front end embeds in the handle groove of latch rear end, is resisted against on positioning key rear end, and handle front end is hinged by lateral pin and latch rear end.
Object of the present invention can also further realize by following technical measures.
Aforesaid latch positioning and locking device, wherein said latch front end is taper type.
Aforesaid latch positioning and locking device, wherein said handle is flake handle, and handle one end is cam structure, and the other end is circle structure, and when latch stretches out locking, the plane of handle front end is resisted against on positioning key rear end.
Aforesaid latch positioning and locking device, wherein the center, lateral pin hole of handle is less than the center, lateral pin hole of handle to the distance A of cam profile peak to the distance L of handle front end plane, and cam is stretched journey A-L and is latch stroke.
Compact structure of the present invention, technique are simple, simple operation, cost is low, it is little, safe and reliable to take up room, applicability is wide, it is time saving and energy saving to use and possess Rapid positioning locking ability, the present invention utilizes the mild increase of cam profile lift to promote the movement of latch, as long as handle is rotated to 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 quick locking and the quick release of the plurality of devices such as vehicle-mounted hanging ladder in van or vehicle mounted square cabin, cable disc, portable power generation unit.
Advantage and disadvantage of the present invention, by for illustration and explanation the non-limitative illustration by preferred embodiment below, these embodiments, only provide as an example with reference to accompanying drawing.
Brief description of the 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 drawings and Examples, the invention will be further described.
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 side direction both sides from base body 11, upper plate 12 two ends are provided with tapped hole 13, by fastening screw trip bolt 14, pedestal 1 is fixed on the mobile platform of van or vehicle mounted square cabin and so on, the pedestal 1 of the present embodiment is fixed on the angle steel 8 of van or vehicle mounted square cabin by 2 fastening screw trip bolts 14.The pedestal hole 111 connecting before and after base body 11 is provided with, latch 2 is slidably matched with pedestal hole 111, latch 2 front ends are taper type, and telescopically turnover is locked in equipment, and taper type structure is convenient to enter in the positioning hole of the equipment of being locked behind latch 2 front end centering location.
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 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 by passing across the lateral pin 6 of latch 2 rear ends and handle 3 rear ends, and lateral pin 6 two ends are spacing by passing across the pin 7 of lateral pin 6 respectively, prevent that it from coming off.
Handle 3 one end are cam structure 31, and the other end is circle structure 32, are convenient to finger and catch on annulus 32 and carry out the rotating operation of handle 3.When latch 2 stretches out locking, the plane 33 of handle 3 front ends is resisted against on positioning key 4 rear ends.The center, lateral pin hole of handle 3 is less than the lateral pin Kong61 center of handle to the distance A of cam profile peak to the distance L of handle front end plane 33, cam is stretched journey A-L and is latch stroke, can determine 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 as shown in double dot dash line in Fig. 3 counterclockwise gently around lateral pin Kong61 center, handle 3 overcomes the elastic force of spring 5, and from original handle 3, Transverse plane 33 is resisted against on positioning key 4 rear ends, turns to cam profile peak and is resisted against on positioning key 4 rear ends, the elastic force having produced when now lateral pin 6 has overcome spring 5 pressurized, pulls latch 2 to move to right and departs from the equipment that is locked.
When the equipment of being locked need to be locked, catch on annulus 32 with finger, handle 3 is rotated clockwise gently around center, lateral pin hole, under the elastic force effect that latch 2 resets at spring 5, automatically move to left, until the front Transverse plane 33 of handle 3 is resisted against on positioning key 4 rear ends, now in the rapid positioning hole that injects the equipment that is locked of latch 2, complete locking.
Due to the elastic force effect that spring 4 resets, make the rotation of handle 3 of the present invention very flexible, the positioning hole that latch 2 exits the equipment of being locked gently completes release, or the positioning hole that automatically fast injects the equipment that is locked to complete locking all very reliable.
In addition to the implementation, 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.
