Description

Technical Field

[0001] The present application relates to the technical field of locks, and in particular to a lock structure capable of realizing automatic locking. Background Art

[0002] The current automatic lock industry is developing rapidly, with a clear trend towards intelligence and networking, meeting the security needs of many residential and commercial places. However, in specific areas such as courtyard doors, fence doors and enclosure doors, there is a lack of efficient automatic lock solutions designed for these outdoor environments.

[0003] One problem is that existing automatic locks are highly dependent on electricity. Conventional automatic locks cannot guarantee normal locking when the power is off, which reduces safety. In addition, the complex electronic structure makes the maintenance work highly specialized. Once a failure occurs, users face the dilemma of long maintenance cycles and high costs. Although there are remote-controlled smart locks on the market that try to solve these problems, remote monitoring and management through the Internet to reduce maintenance pressure, this type of product has high development costs and technical integration, and the final price is expensive, which limits its market penetration.

[0004] Therefore, the purpose of this application is to develop an automatic lock that is structurally sound, easy to maintain and install, convenient to use, and cost-controlled.

[0005] The above contents are only used to assist in understanding the technical solution of the present application, and do not constitute an admission that the above contents are the closest prior art to the present application. Summary of the invention

[0006] Based on this, the present application provides a lock structure that realizes automatic locking to solve one of the above technical problems.

[0007] The technical solution adopted by the present application to solve its technical problems is to include: a door body, including a door panel and a door frame; a main panel, fixedly arranged on the door frame, formed with an upper guide ring and a lower guide ring, and the lower guide ring is provided with an inverted T-shaped positioning groove; a locking column, movably arranged in the upper guide ring and the lower guide ring, with an inclined lever opening formed at the bottom end, and a cylindrical protrusion formed above the inclined lever opening, which moves in the inverted T-shaped positioning groove; a sub-panel, fixedly arranged on the door panel, formed with a long strip locking block, which is used to abut the inclined lever opening and drive the locking column to move upward until the locking column automatically falls back without abutment, thereby completing the limit locking of the long strip locking block by the locking column.

[0008] In some embodiments, at least a portion of the elongated locking block extends out of the door panel.

[0009] In some embodiments, the main panel and the auxiliary panel are fixedly connected to the door body by screws or rivets.

[0010] In some embodiments, the thickness of the elongated locking block is smaller than the distance between the locking column and the door frame.

[0011] In some embodiments, the outer diameter of the locking column is smaller than the inner diameters of the upper guide ring and the lower guide ring.

[0012] In some embodiments, the height of the elongated locking block is equal to the inclined surface force lever.

[0013] In some embodiments, a protrusion is formed on the top end of the locking column to abut against the upper end of the upper guide ring.

[0014] The beneficial effect of the present application is that the inertia generated when the door is closed drives the long strip locking block into the back of the locking column to achieve a self-locking effect. The lock is simple to operate, low in cost, simple to maintain, easy to install and convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to achieve. When the combination of technical solutions is contradictory or cannot be achieved, it should be considered that the combination of such technical solutions does not exist and is not within the scope of protection of this application.

[0023] In the embodiments of this application, please refer to Figure 1-5 As shown, the present application provides a lock structure for realizing automatic locking, mainly comprising: a door body 1, including a door panel 11 and a door frame 12; a main panel 2, fixedly arranged on the door frame 12, formed with an upper guide ring 21 and a lower guide ring 22, and the lower guide ring 22 has an inverted T-shaped positioning groove 23; a locking column 3, movably arranged in the upper guide ring 21 and the lower guide ring 22, with an inclined surface force-leveraging opening 33 formed at the bottom end, and a cylindrical protrusion 31 is formed above the inclined surface force-leveraging opening 33, which moves in the inverted T-shaped positioning groove 23; a sub-panel 4, fixedly arranged on the door panel 11, formed with a long strip locking block 41, which is used to abut the inclined surface force-leveraging opening 33 and drive the locking column 3 to move upward until the locking column 3 automatically falls back without abutment, thereby completing the limit locking of the long strip locking block 41 by the locking column 3.

[0024] By means of the inertia generated when the door is closed, the locking column 3 applies force to the inclined surface force-taking opening 33, and the locking column 3 moves upward until it reaches the top of the long strip locking block 41, after which the locking column 3 naturally falls, and the long strip locking block 41 enters the back of the locking column 3, and finally the cylindrical protrusion 31 is rotated left and right to prevent the door from being opened.

[0025] Some preferred / improved embodiments based on the above embodiments will be described below. Any one of the following embodiments may be selected, or multiple embodiments may be selected and combined.

[0026] Reference Figure 1 As shown, in order to enable the elongated locking block 41 to drive the lock to close through the inertia of closing the door, at least a portion of the elongated locking block 41 extends out of the door panel 11 .

[0027] Preferably, the main panel 2 and the auxiliary panel 4 are fixedly connected to the door body 1 by screws or rivets.

[0028] Reference Figure 2As shown, in order for the long strip locking block 41 to enter between the locking column 3 and the door frame 12 when the door leaf is fully closed, the thickness of the long strip locking block 41 is smaller than the distance between the locking column 3 and the door frame 12 .

[0029] Specifically, the outer diameter of the locking column 3 is smaller than the inner diameters of the upper guide ring 21 and the lower guide ring 22. This arrangement reduces the gap between the locking column 3 and the guide ring, ensuring that the locking column 3 can rise and fall smoothly during movement.

[0030] Reference Figure 1 As shown, in order to enable the long strip locking block 41 to smoothly lift the locking column 3 when closing, the height of the long strip locking block 41 is equal to the inclined surface force-leveraging opening 33 .

[0031] Reference Figure 2-3 As shown, in order to keep the locking column 3 at a certain height under normal conditions, a convex portion 32 is formed at the top end of the locking column 3 to abut against the upper end of the upper guide ring 21 .

In order to avoid obscuring the concept of the present application, some details known in the art are not described. Based on the above description, those skilled in the art can fully understand how to implement the technical solution disclosed herein.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present application, and the aforementioned embodiments are only used to illustrate the technical solution of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, a person of ordinary skill in the art should understand that it is still possible to modify the technical solutions recorded in the aforementioned embodiments, or to make equivalent replacements for some of the technical features therein.
