Description

Technical Field

[0001] The utility model relates to the technical field of door latches, in particular to an anti-slip door latch. Background Art

[0002] The door latch is a locking device that keeps two door leaves in a closed state, and mainly includes a pin seat arranged on the door leaves and a slidable latch arranged in the pin seat.

[0003] Most of the existing latches are L-shaped latches, which have a simple structure and are convenient to use. However, such latches are not very reliable. When opening the door, the latch is easily pulled out excessively and causes the latch to slip. Summary of the invention

[0004] The technical problem to be solved by the utility model is to provide a door latch which has a simple structure and low manufacturing cost and can prevent a latch pin from sliding off when in use.

[0005] The utility model is implemented as follows: an anti-slip door latch, comprising

[0006] A latch, comprising a crossbar and a handle, wherein the handle is arranged at one end of the crossbar, and a limit groove is provided on the bottom wall of the crossbar along its length direction, wherein the length of the limit groove is less than the length of the crossbar;

[0007] At least two pin seats are fixed on the two door leaves respectively by bolts, and the pin seats are each provided with a pin hole, and the cross bar is movably inserted into the pin hole. A top screw is provided in the pin hole of the pin seat close to the handle, and the top screw is top-set in the limit groove.

[0008] Furthermore, the front side of the pin seat has a threaded hole, and a decorative cover is screwed onto the threaded hole. The decorative cover can be used to cover the bolts to make the pin seat more beautiful.

[0009] Furthermore, the depth of the limiting groove is 3 mm.

[0010] Furthermore, a lock hole is provided at the other end of the cross bar for a padlock.

[0011] Furthermore, the number of the pin seats is 4, which are evenly fixed on the two door leaves.

[0012] The advantages of the utility model are: the utility model has a simple structure, is easy to operate, and has a low manufacturing cost. By arranging a limit groove on the cross bar and arranging a top screw on the pin seat, the top screw limits the maximum pull-out limit of the cross bar, thereby preventing the cross bar from being pulled out excessively and causing the pin to fall off.

[0017] Description of the accompanying drawings: latch 1, cross bar 11, lock hole 111, limiting groove 112, handle 12, pin seat 2, bolt 21, pin hole 22, top screw 23, threaded hole 24, decorative cover 25, door leaf 3. DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] The technical problem to be solved by the utility model is that when the existing latch is used to open the door, the latch is easily pulled out excessively and causes the latch to slip.

[0020] The utility model solves the technical problem by providing a limit groove on the latch and a top screw on the pin seat, so as to limit the maximum pull-out limit of the latch by the top screw and prevent the cross bar from being pulled out excessively and falling off.

[0021] like Figures 1 to 3As shown, the utility model is an anti-slip door latch, comprising a latch pin 1 and at least two pin seats 2; the latch pin 1 comprises a cross bar 11 and a handle 12, the handle 12 is arranged at one end of the cross bar 11, and the cross bar 11 is conveniently plugged and unplugged by arranging the handle 12, the other end of the cross bar 11 is provided with a lock hole 111, and a padlock can be hung on the lock hole 111 when necessary, and the bottom wall of the cross bar 11 is provided with a limiting groove 112 along its length direction, the length of the limiting groove 112 is less than the length of the cross bar 11, and the depth of the limiting groove 112 is 3mm; preferably, the number of the pin seats 2 is 4, respectively through The bolts 21 are fixed on the two door leaves 3 respectively, and the pin seats 2 are provided with pin holes 22. The cross bar 11 is movably inserted into the pin holes 22. A top screw 23 is provided in the pin hole 22 of the pin seat 2 close to the handle 12. The top screw 23 is top-set in the limiting groove 112. The front side of the pin seat 2 has a threaded hole 24, and a decorative cover 25 is screwed on the threaded hole 24. When installing the pin seat 2, the installation tool can pass through the threaded hole 24 to facilitate tightening the bolt 21, so that the pin seat 2 is fixed on the door leaf 3. The decorative cover 25 can be used to cover the threaded hole 24 and the bolt 21 to make the pin seat 2 more beautiful.

[0022] The utility model has the advantages of simple structure, convenient operation and low manufacturing cost. By arranging a limit groove 112 on the cross bar 11 and a top screw 23 on the pin seat 2, when the door leaf is opened, the cross bar 11 is pulled outward by holding the handle 12, and at the same time, the top screw 23 is used to limit the maximum pulling-out limit of the cross bar 11 to prevent the cross bar 11 from being excessively pulled out and falling.

[0023] Although the specific implementation methods of the present invention are described above, those skilled in the art should understand that the specific embodiments described are only illustrative and are not intended to limit the scope of the present invention. Equivalent modifications and changes made by those skilled in the art in accordance with the spirit of the present invention should be included in the scope of protection of the claims of the present invention.
