Abstract

The utility model relates to a plug, which is composed of a casing body and a plug rod. The utility model is also provided with a button slice, a spring and a split baffle ring. The upper bottom of the button slice is provided with a convex button which is consistent with an opening hole on the bottom of the casing body, a recess of the plug rod is provided with the split baffle ring, and the spring is positioned between the split baffle ring and the bottom side of the bottom slice. When a user pulls a pulling ring of the plug rod, the spring is compressed. At the time, the convex button on the button slice is inserted into the opening hole of the casing body and locked. The plug can be unlocked without very large force. When the convex button is pressed, the convex button moves away from the opening hole of the casing body. Owing to the spring action, the plug rod can be sent back to the original position, and thus, the plug is locked.

Description

Resilient latches

The utility model relates to a kind of furnature construction spare, is a kind of latch specifically.

Before the utility model design is finished, the latch that uses on the furniture generally has the structure that bolt rod is moved on bolt rod, as doing the shape that meets at right angles to bolt rod, the minor face at right angle can rotate around its axle, when needs were extracted bolt rod out, people pulled out bolt rod with the right angle minor face that hand is stirred bolt rod, when needs lock, the right angle minor face that people stir bolt rod with hand inserts bolt rod, so just cumbersome, if latch gets rusty, pull is just relatively more difficult.Before finishing, the utility model design do not see in the document record as yet relevant for the latch of the utility model structure, do not see on the market relevant for the latch of the utility model structure and sell, do not see people use the utility model structure in life latch yet.

The purpose of this utility model provides a kind of resilient latches, when needs are extracted bolt rod out, as long as people draw draw ring, bolt rod just can be drawn out, and locking is when needs lock, as long as people click protruding button, lean on the elastic force of spring just bolt rod can be inserted, finish locking.

The utility model is realized with following technical proposals:

A kind of latch, by housing, bolt rod is formed, it also has button piece, spring and split washer, bottom at housing, one perforate is arranged, at the long side of housing two ends, one hole is respectively arranged, both wings at housing, screw hole is arranged, and the side of button piece is the  type, its three faces, face A and upper bottom surface C are 90 ° of angles, upper bottom surface C and face B are 92 °-93 ° in obtuse angle, and a protruding button is arranged on the C of bottom surface thereon, its size is consistent with the perforate of housing bottom, the perforate of housing bottom and protruding button are square, and square type or round respectively has a hole in its both sides, fluted on the bolt rod, groove is identical with the distance of button piece both sides apart from the distance of bolt rod one end, and groove is identical with the distance at the long side of housing two ends apart from the distance of groove, and the external diameter of bolt rod is more smaller than the hole on housing and button piece, spring is between an end of groove and bolt rod, on groove, split washer is arranged, at an end of latch draw ring is arranged, housing and button piece can be 1 millimeter steel disc to 2 millimeters thickness, and the height of the protruding button on the button piece is a little more than the thickness of the steel disc of housing.

The utility model has following good effect;

Because the groove at bolt rod has split washer, spring is between the bottom side of split washer and button piece, when drawing the draw ring of bolt rod, spring is subjected to the effect of power, be compressed, this moment the protruding button on the button piece, the perforate of inserting housing, locking, need not with very big power, latch promptly is opened, during protruding button on clicking the button piece that is exposed at the housing outside, protruding button leaves the perforate of housing, because the effect of spring sends back to original position with bolt rod, latch is in the lock state, as long as one press gently, latch is lockable both.

Below in conjunction with drawings and Examples structure of the present utility model is done further detailed explanation:

Fig. 1 is a unit assembly drawing in addition of the present utility model;

Fig. 2 is the state diagram of the utility model when locking;

Fig. 3 is the state diagram of the utility model when the draw ring of bolt rod is drawn back;

Fig. 4 is a structural representation of the present utility model;
