Abstract

The utility model discloses a locking device. The locking device comprises a fixed piece, a gasket and a movable lock catch which can move relative to the gasket and move between an unlocking position and a locking position; the movable lock catch is provided with a slide groove which extends along the length direction; the gasket is vertically provided with a positioning pin; the positioning pin is inserted into the slide groove; the slide groove and the positioning pin are slidingly and rotatably matched; a concave position is formed in the upper surface of the fixed piece; the end part of the movable lock catch is provided with a hook which is buckled into the concave position when the movable lock catch is located on the locking position. According to the locking device disclosed by the utility model, the hook can be driven to move by utilizing the movement of the movable lock catch; locking can be realized by matching the hook with the concave position of the fixed piece; the hook is maintained on the concave position under the effect of gravity so that a spring does not need to be used and the service life of the locking device can be effectively prolonged; the locking device can rapidly and conveniently realize the locking and the locking effect can also be ensured.

Description

Locking device

Technical field

The utility model relates to a kind of locking device.

Background technology

Well-known, locking device is widely used in various device, casing etc., for example, can be used in be used to collecting the removable garbage truck casing of rubbish and transhipment rubbish, locks with the back door for by this casing.

Existing locking device comprises fixture, gripper shoe, be articulated on gripper shoe and the handle that connects by spring, be articulated in the latch hook on handle.Now this locking device being applied to the removable garbage truck casing is illustrated, described fixture is fixed on the back door of casing, gripper shoe is fixed on the sidewall of casing, when needs locking sidewall and back door, pull handle latch hook is caught on to fixture, to realize locking, when needs are opened back door, pull handle latch hook and fixture are broken away from, can realize unblanking of case rear door.But after use after a while, follow the string thereby spring easily produces fatigue, cause the locking of locking device to be lost efficacy, thereby affect the application life of locking device.

The utility model content

In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of locking device of long service life.

For addressing the above problem, the technical scheme that the utility model adopts is as follows:

Locking device, comprise fixture, pad, the movable snap close that can move between lockset position of coupler and latched position with respect to pad; Described active lock is buckled and is provided with the chute extended along its length, on described pad, is vertically installed with an alignment pin, and described alignment pin is inserted in chute, and this chute and alignment pin slide and be rotatably assorted; The upper surface of fixture is provided with recess, the end of described movable snap close be provided with when the active lock buckle during in latched position be used to buckling into the hook on recess.

The center of gravity of movable snap close overlaps with the central point of chute.

Described pad is positioned at a side of fixture, and during in latched position, described alignment pin is positioned at the rearward end of chute when the active lock buckle.

Described pad is positioned at a side of fixture, and the bearing of trend of pad is vertical with the bearing of trend of fixture.

Described fixture comprises substrate, is arranged on the baffle plate of upper surface of base plate, forms between the upper surface of this recess by the sidewall of baffle plate and substrate.

Described hook comprises crossbeam section, the vertical beam section be connected with crossbeam section; During in latched position, the crossbeam section of described hook is located on recess when the active lock buckle, and vertical beam section is positioned at a side of fixture.

Compared to existing technology, the beneficial effects of the utility model are:

The utility model is by the motion of utilization activity snap close, can drive hook mobile, and links up with and the coordinating of fixture recess by utilization, can realize locking, and therefore this hook maintains on recess, under the effect of gravity, without adopting spring, can effectively extend the application life of locking device; And, when locking device is in unlocking condition, by promoting movable snap close, active lock is buckled under Action of Gravity Field move downward, and buckles on the recess of fixture, thereby realize locking quickly and easily, can also guarantee its locking effect.

The accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the schematic diagram that the utility model is in the lock state;

Fig. 3 is the schematic diagram that the utility model is in unlocking condition;

Wherein, 1, fixture; 2, pad; 21, alignment pin; 3, movable snap close; 31, chute; 32, hook.

The specific embodiment

Below, by reference to the accompanying drawings and the specific embodiment, the utility model is described further, so that clearer, understand the utility model technical thought required for protection.

As shown in Figure 1, be a kind of locking device of the utility model, comprise fixture 1, pad 2, the movable snap close 3 that can move with respect to pad 2 between lockset position of coupler and latched position; On described movable snap close 3, be provided with the chute 31 extended along its length, on described pad 2, be vertically installed with an alignment pin 21, described alignment pin 21 is inserted in chute 31, this chute 31 slides and is rotatably assorted with alignment pin 21, that is to say, this chute 31 can slide and rotate with respect to alignment pin 21, thereby utilizes the movement locus of the interaction restriction activity snap close 3 of chute 31 and alignment pin 21; The upper surface of fixture 1 is provided with recess, and the end of described movable snap close 3 is provided with when movable snap close 3 is in latched position be used to buckling into the hook 32 on recess.Preferably, described pad 2 is positioned at a side of fixture 1, and the bearing of trend of pad 2 is vertical with the bearing of trend of fixture 1.Described fixture 1 comprises substrate, is arranged on the baffle plate of upper surface of base plate, forms between the upper surface of this recess by the sidewall of baffle plate and substrate.Described hook 32 comprises crossbeam section, the vertical beam section be connected with crossbeam section; When movable snap close 3 was in latched position, the crossbeam section of described hook 32 was located on recess, and vertical beam section is positioned at a side of fixture 1.The utility model is by rationally arranging the annexation of each part, can make its structure comparatively simple, install more for convenience, also can avoid the short-board effect of a plurality of parts.

The center of gravity of movable snap close 3 overlaps with the central point of chute 31.As shown in Figure 2, when movable snap close 3 was in latched position, described alignment pin 21 was positioned at the rearward end of chute 31.

Now this locking device being applied to the removable garbage truck casing is illustrated.In use, fixture 1 is fixed on the back door of casing, and pad 2 is fixed on the sidewall of casing, as shown in Figure 2, by promoting movable snap close 3, movable snap close 3 is moved downward under the effect of gravity, now, chute 31 rotates and slides with respect to alignment pin 21, and when the rear end of chute 31 moved to alignment pin 21, movable snap close 3 was in latched position, hook 32 buckles on the recess of fixture 1, thereby realizes the connection locking at sidewall and back door; As shown in Figure 3, by the promotion activity snap close 3 that makes progress, make to link up with 32 and break away from fixture 1, can realize unclamping of sidewall and back door.

Certainly, described locking device also can be applicable to other casings, equipment etc., and with for two objects are locked, and in use, this fixture 1 is fixed therein on an object, and pad 2 is fixed on another object.

Above-mentioned embodiment is only preferred embodiment of the present utility model; can not limit with this scope of the utility model protection, the variation of those skilled in the art does on basis of the present utility model any unsubstantiality and replacement all belong to the utility model scope required for protection.
