Abstract

Provided is a plug pin assembly mainly composed of a plug pin and a matched socket. The plug pin comprises a plug pin rod equipped with a handle on the tail portion thereof. The plug pin rod is sleeved with a fixed plug pin socket sleeve in which at least one spring sleeving the plug pin rod is installed. One end of the spring is abutted against the fixed plug pin socket sleeve, while the other end of the spring presses a spring collar disposed on the plug pin rod. At least one protruded column is arranged transversely on the head portion of the plug pin rod. The socket is equipped with a jack used for inserting in the head portion of the plug pin rod. An L-shaped slot is disposed on the circumferential wall of the jack and extended vertically from the edge of a jack end. The protruded column can be inserted into the L-shaped slot. The plug pin assembly has characteristics of simple structure, easy and reliable use, flexible switching, and high plugging intensity.

Description

Latch assembly

Technical field

The utility model relates to a kind of latch assembly, belongs to hardware-joint technical field.

Background technology

Latch is as a kind of conventional hardware-joint; no matter in daily life, or on some box work or equipment, often can use existing common latch; mainly formed by bolt rod, Fixed latches cover for seat and the socket that matches with bolt rod; its structure is comparatively simple, and the fastness of grafting is poor, close or open underaction, speed is slow; poor reliability; use inconvenience, the hand of easily accidentally injuring user, poor practicability.

Utility model content

The purpose of this utility model is to overcome the deficiency that prior art exists, and provides a kind of simple in structure, easy to use, reliable, and switch is flexible, the latch assembly that grafting fastness is strong.

The purpose of this utility model completes by following technical solution, it is mainly made up of a latch and a supporting socket, described latch comprises the bolt rod of an afterbody with handle, this bolt rod is coated with a Fixed latches cover for seat, at least one spring being nested with on bolt rod is installed in Fixed latches cover for seat, one end of described spring compresses in Fixed latches cover for seat, and the other end is pressed on the check ring arranging on bolt rod; The head of described bolt rod is horizontally arranged with at least one projection; On described socket, be provided with a jack that can insert for bolt rod head, and on the perisporium of described jack, be provided with a L shaped slot that vertically starts from jack end edge to extend internally, can insert for projection.

In described Fixed latches cover for seat, divide two springs are installed up and down, in Fixed latches cover for seat between two springs, be provided with a middle springs back-up ring, another upper and lower in the relative Fixed latches cover for seat of described bolt rod, be respectively arranged with the upper spring back-up ring and the lower spring back-up ring that supply upper spring and lower spring to compress.

The afterbody of described bolt rod is provided with the shaft-like handle that is bent into 90 degree; On the outer wall of described Fixed latches cover for seat, be provided with fixed head or the fixed block with fixing hole.

The head of described bolt rod is horizontally arranged with two projections that are arranged symmetrically with, and correspondingly on the perisporium of described jack, is provided with the L shaped slot that two of being arranged symmetrically with insert for two projections respectively.

The features such as the utility model is actually a kind of night bolt, is the one improvement to prior art, and it has simple in structure, and easy to use, reliable, switch is flexible, and grafting fastness is strong.

Embodiment

Below in conjunction with accompanying drawing, the utility model is shown in detailed introduction: Fig. 1,2,3, the utility model is mainly made up of a latch 1 and a supporting socket 2, described latch 1 comprises the bolt rod 12 of an afterbody with handle 11, this bolt rod 12 is coated with a Fixed latches cover for seat 3, at least one spring 4 being nested with on bolt rod 12 is installed in Fixed latches cover for seat 3, one end of described spring 4 compresses in Fixed latches cover for seat 3, and the other end is pressed on the check ring 13 arranging on bolt rod 12; The head of described bolt rod 12 is horizontally arranged with at least one projection 14; On described socket 2, be provided with a jack 21 that can insert for bolt rod 12 heads, and on the perisporium of described jack 21, be provided with a L shaped slot 22 that vertically starts from jack end edge to extend internally, can insert for projection.

Shown in figure, in described Fixed latches cover for seat 3, divide two springs 4 are installed up and down, in Fixed latches cover for seat 3 between two springs 4, be provided with a middle springs back-up ring 31, another upper and lower in the relative Fixed latches cover for seat 3 of described bolt rod 12, be respectively arranged with the upper spring back-up ring 131 and the lower spring back-up ring 132 that supply upper spring 41 and lower spring 42 to compress.

The afterbody of described bolt rod 12 is provided with the shaft-like handle 11 that is bent into 90 degree; On the outer wall of described Fixed latches cover for seat 3, be provided with fixed head 33 or the fixed block with fixing hole 32.

The head of bolt rod 12 described in the utility model is horizontally arranged with two projections 14 that are arranged symmetrically with, and correspondingly on the perisporium of described jack 21, is provided with the L shaped slot 22 that two of being arranged symmetrically with insert for two projections respectively.

When use, by supporting fixing respectively to Fixed latches cover for seat 3 and socket 2, under normal condition, bolt rod 12 is under the effect of spring, and its head leaves socket 2, in latch open mode; Need to close (grafting) time, by handle pressing bolt bar 12, overcome in the situation of spring force, the head of shank 12 inserts in the jack 21 of socket 2, and the projection 14 of shank head enters in the vertical channel in L shaped slot 22 thereupon, and plays a kind of guide effect, projection 14 is inserted into behind vertical channel bottom, make shank rotation by handle 11, projection 14 enters the level trough in L shaped slot 22 thereupon, thereby realizes locking latch function.Otherwise when needs are opened latch, as long as by handle 11 rotary insertion extension bars, projection 14 is proceeded to vertical channel from level trough, now, because being subject to the effect of spring force, shank automatic retracted, leaves socket, realizes opening.
