[0024] In order to more clearly illustrate the present invention, the present invention is further described below in conjunction with the accompanying drawings.

[0025] In the following description, the example details are given to provide a deeper understanding of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. It should be understood that the specific embodiments are only used to explain the utility model, and are not used to limit the utility model.

[0026] It should be understood that when the terms "include" and / or "comprises" are used in this specification, they indicate the existence of the stated features, integers, steps, operations, elements or components, but do not exclude the existence or addition of one or more other features, integers, steps, operations, elements, components or combinations thereof.

[0027] In modern society, with the development of science and technology, the form of locks is also constantly improving and evolving. A general lock includes a reciprocating lock tongue, and the reciprocating movement of the lock tongue realizes the locking state and the unlocking state of the object. However, it is found in actual production that the linkage structure of the lock tongue often requires elastic parts to achieve linkage. The linkage structure is complex and difficult to assemble, and the performance will fatigue due to the increase in service life. Therefore, a locking device with a more reasonable structure is urgently needed to solve the above problems.

[0028] In order to solve the above technical problems, the present application provides a locking device, see the attached Figure 1 To Attachment Figure 4, including a main body 1, a lock tongue 2 and a push rod 3, wherein the surface of the main body 1 is provided with a receiving groove 11, and the non-installation end of the main body 1 is provided with a movable hole; the surface of the lock tongue 2 is provided with a linkage groove 21, and one end of the push rod 3 is rotatably connected to the groove wall of the linkage groove 21 on both sides, and the other end can reciprocate and retract in the movable hole; the first end of the lock tongue 2 is flip-connected with the main body 1, and the second end is based on the reciprocating movement of the push rod 3 to form a locked state protruding from the receiving groove 11 or an unlocked state accommodated in the receiving groove 21. The above-mentioned rotation connection and flip connection can be achieved by a rotating column with a rotating groove or a rotating pin and other structures. This part is the existing technology, so it is not repeated here; through the linkage groove 11, the lock tongue 2 and The push rods 3 cooperate with each other to achieve the locking and opening states of the lock with the outside without the help of an elastic structure, and the structure is simpler and easier to assemble and produce; the specific installation plan is as follows: the lock is placed in the door panel, and one end of the push rod 3 is made to protrude from the panel surface of the door panel. The user only needs to control the extension and retraction of the push rod 3 to control the state of the lock tongue 2. Further, when the push rod 3 is retracted into the storage groove, the second end of the lock tongue 2 rotates around its first end, and the lock tongue is accommodated in the lock groove of the door frame to achieve locking of the door body; naturally, it is only necessary to control the push rod to protrude out of the door panel, and the push rod pulls the lock tongue to be stored in the storage groove. At this time, there is no interference contact between the lock tongue 2 and the lock groove, thereby achieving free opening of the door body.

[0029] In this embodiment, sliding columns 31 are further provided on both sides of the push rod 3, and the two opposite side walls of the storage groove 11 are provided with sliding waist holes 12 adapted to the sliding columns; through the cooperation between the sliding columns 31 and the sliding waist holes 12, the push rod 3 can achieve stable reciprocating motion inside the storage groove 11, and the push rod is not easy to fall out of the storage groove 11.

[0030] In this embodiment, in order to achieve the locking tongue 2 to stop at a certain angle, in this embodiment, the movable hole is a threaded hole, and the end of the push rod 3 away from the lock tongue 2 is provided with a mounting groove 32; it also includes a threaded rod 4, one end of the threaded rod 4 is passed through the threaded hole and connected to the mounting groove 32, and the other end protrudes out of the movable hole; it is not difficult to understand that by matching the threaded rod 4 and the threaded hole, the threaded rod 4 can be screwed in and out to change the telescopic degree of the push rod 3, and based on the threaded structure, it can be stopped at a certain telescopic position.

[0031] In a more preferred solution, the assembly groove 32 extends to one side of the push rod to form an assembly opening, and an annular groove 42 is provided at one end of the threaded rod 4 close to the push rod 3, and the annular groove 42 is movably engaged with the assembly opening; the assembly combination of the push rod 3 and the threaded rod 4 is realized through the engaging assembly style. During actual installation, it is only necessary to first assemble the lock tongue 2 and the push rod 3 in the receiving groove 11, and then screw the threaded rod 4 into the receiving groove 11 through the active opening, and movably engage the push rod 3 through the assembly opening. The specific engaging method is to set a protruding clamping piece on the inner wall forming the assembly opening, and the clamping piece extends into In the annular groove 42, it can be achieved that the normal movement of the push rod 3 can be ensured during the reciprocating extension and retraction process, and the state of mutual abutment between the threaded rod 4 and the push rod 3 can be ensured; in a more optimal solution, a limit plate 33 is also provided at one end of the push rod 3 close to the threaded rod 4, and the limit plate 33 is clamped in the annular groove 42 through the installation notch. It can be specifically understood that the installation notch is a U-shaped groove, so that the limit plate 33 is clamped in the annular groove, and there is a preset margin spacing between the annular groove 42 and the limit plate 44, so that the annular groove 42 and the limit plate 33 are in real time abutment in the storage groove 11.

[0032] In a more optimal solution, a bowl-shaped groove 34 is provided on the inner end surface of the assembly groove 32, and the end of the threaded rod 4 close to the push rod is a hemisphere and fits into the bottom of the bowl-shaped groove 34; the end of the push rod 3 designed as a hemisphere fits into the bowl-shaped groove 34, making it less likely for the lock tongue 2 to get stuck during the extension and storage process, making the cooperation between the push rod 3 and the threaded rod 4 smoother.

[0033] In this embodiment, a limit cap 41 is further provided at one end of the threaded rod 4 away from the push rod 3; the limit cap 41 can prevent the push rod from being fully extended into the receiving groove, thereby forming a stable insertion diameter.

[0034] In this embodiment, the mounting end of the main body 1 is also used for mounting a hook 13, which can be installed in the door body in conjunction with a screw structure through the hook 13.

[0035] The advantages of the utility model are:

[0036] 1) Through the cooperation of the linkage groove, the lock tongue and the push rod, the lock can be locked and opened with the outside without the need for an elastic structure, and the structure is simpler and easier to assemble and produce;

[0037] 2) The hemispherical design of the push rod end fits in with the bowl-mounted groove, making it less likely for the lock tongue to get stuck during extension and retraction, and making the push rod and threaded rod fit more smoothly.

[0038] The above disclosures are only several specific embodiments of the present invention, but the present invention is not limited thereto, and any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
