Description

Technical Field

[0001] The utility model belongs to the technical field of locks, and particularly refers to a connection structure of a bolt box. Background Art

[0002] A bolt box is a tool installed on a door frame, usually installed on the side of a door or a door frame. When the user closes the door, the bolt tongue can be inserted into the bolt box to complete the door closing. The current bolt box consists of a box body, a panel covering the box body, and an adjustment box arranged inside the box body. The panel is connected to the box body by screws. During assembly, a screwdriver is needed to tighten the panel and the box body to ensure a stable connection. However, when the user rotates the screw, the judgment of the number of rotations and whether it is tightened is not accurate enough. Some people will stop rotating when they can no longer turn the screw and think that it is tightened at this time. At this time, the box body will be deformed due to the downward pressing pressure of the panel. If the screw is tightened excessively multiple times, the box body will be deformed and become less compatible with the door frame. Therefore, there is a need for a connection between the panel and the box body to support the panel and prevent the box body from deforming. Summary of the Invention

[0003] The purpose of the utility model is to provide a bolt box with a simple structure, which is connected between the panel and the box body to support the panel and prevent the box body from deforming.

[0004] The purpose of the utility model is achieved as follows:

[0005] A connection structure of a bolt box includes a box body embedded in a door frame and a panel covering the box body. A bolt tongue groove for the bolt tongue to extend into is provided on the panel. A plurality of support plates are arranged inside the box body. Hook rods protrude outward from both sides of the support plates. Buckle parts adapted to the hook rods are provided on both sides of the box body. Buckle openings are provided on the buckle parts. The support plates are restricted from moving horizontally by inserting the hook rods into the buckle openings. The hook rods include a plugging part and a abutting part. The abutting part is bent upward relative to the plugging part. When the plugging part is inserted into the buckle opening, the support plate is controlled to move upward, and the inner end of the abutting part abuts against the buckle part.

[0006] Further, an upper inclined surface is provided at the end of the abutting part. The buckle part is concave. When the abutting part moves upward, the upper inclined surface abuts against the concave part. An activity baffle is also provided on the buckle part. Both sides of the activity baffle are partitioned from the buckle part.

[0007] Further, a side groove is concavely provided on the side surface of the support plate. The side groove is located below the plugging part. A lower inclined surface is also provided at the lower end of the side groove. When the plugging part is inserted into the buckle opening, the support plate is moved upward, and the lower inclined surface abuts against the inner wall of the buckle part.

[0008] Further, a connecting plate is transversely arranged at the upper end of the support plate, and the support plate and the connecting plate are arranged in a bent manner. A screw hole is formed in the connecting plate, and a through hole adapted to the screw hole is formed in the panel. A screw can penetrate through the through hole, and when the screw passes through the through hole and is connected to the screw hole, the support plate can be driven to move upward.

[0009] The prominent and beneficial technical effects of the present utility model compared with the prior art are as follows:

[0010] The present utility model is a connection structure between a support plate arranged in a plug box and the box body. Currently, the panel and the box body are usually connected and fixed by screwing the screws tightly with a screwdriver. However, when the user rotates, the judgment of the number of rotations and whether it is tightened accurately is insufficient. Some people will stop rotating when they can no longer turn the screw and think that it is tightened at this time. At this time, the box body will be deformed due to the downward pressing pressure of the panel. In order to prevent the user from over-rotating, the present utility model adds a support plate to support outward from both sides and above, so that the box body cannot be deformed. During installation, the support plate is moved downward from above the box body and placed into the box body. During the downward movement of the support plate, the insertion part is inserted into the buckle opening. At this time, the panel is covered on the box body, and the support plate is controlled to move upward. At this time, the limiting part moves upward synchronously, and the inner surface of the limiting part abuts against the outer surface of the box body, and the support plate cannot move. At this time, both sides of the support plate abut against the inner wall of the box body. Even if the panel is tightened forcefully with a screwdriver, the two sides of the box body will also be resisted by the support plate and cannot be deformed inward. Compared with the designs on the market without a support plate, the added support plate of the present utility model can make the box body more stable and not easily deformed. It does not need to be connected by welding or screws, and is connected by a buckling method, which is convenient for the manufacturer to quickly assemble. During assembly, the support plate is moved downward and inserted into the buckle openings on both sides of the box body through the insertion part. At this time, the insertion part and the abutting part are exposed outside the box body. After controlling the support plate to move upward, the inner wall of the abutting part abuts against the outer wall of the buckle part. At this time, the support plate is buckled with the box body, and no additional parts are required for buckling or welding. The operation method is simple and easy to master.

Specific embodiments

[0019] The present utility model will be further described below in conjunction with specific embodiments:

[0020] A connection structure of a bolt box, comprising a box body 1 embedded in a door frame and a panel 2 covering the box body 1. A lock tongue groove 3 for a lock tongue to extend into is provided on the panel 2. A plurality of support plates 22 are provided in the box body 1. Hook rods 23 protrude outward from both sides of the support plate 22. Buckle parts 24 adapted to the hook rods 23 are provided on both sides of the box body 1. A buckle opening 31 is provided on the buckle part 24. The support plate 22 is restricted from moving laterally by inserting the hook rod 23 into the buckle opening 31. The hook rod 23 includes an insertion part 28 and an abutting part 29. The abutting part 29 is bent upward relative to the insertion part 28. When the insertion part 28 is inserted into the buckle opening 31, the support plate 22 is controlled to move upward, and the inner end of the abutting part 29 abuts against the buckle part 24.

[0021] The utility model relates to a connection structure between a support plate 22 arranged in a plug box and a box body 1. Currently, the panel 2 and the box body 1 are usually connected and fixed by screwing screws tightly with a screwdriver. However, when the user rotates, the judgment of the number of rotation turns and whether it is tightened is not accurate enough. Some people will stop rotating when they can no longer turn the screw and think that it is already tightened at this time. At this time, the box body 1 will be deformed due to the downward pressing pressure of the panel 2. In order to prevent the user from over-rotating, the utility model adds a support plate 22 to support outward from both sides and above, so that the box body 1 cannot be deformed. During installation, the support plate 22 is moved downward from above the box body 1 and placed into the box body 1. During the downward movement of the support plate 22, the insertion part 28 is inserted into the buckle opening 31. At this time, the panel 2 is covered on the box body 1, and the support plate 22 is controlled to move upward. At this time, the limiting part moves upward synchronously, and the inner surface of the limiting part abuts against the outer surface of the box body 1, so that the support plate 22 cannot move. At this time, both sides of the support plate 22 abut against the inner wall of the box body 1. Even if the panel 2 is tightened forcefully with a screwdriver, both sides of the box body 1 will be resisted by the support plate 22 and cannot deform inward. Compared with the design without the support plate 22 on the market, the added support plate 22 of the utility model can make the box body 1 more stable and not easily deformed. It does not need to be connected by welding or screws, and is connected by a buckling method, which is convenient for the manufacturer to quickly assemble. During assembly, the support plate 22 is moved downward and the insertion part 28 is inserted into the buckle openings 31 on both sides of the box body 1. At this time, the insertion part 28 and the abutting part 29 are exposed outside the box body 1. After controlling the support plate 22 to move upward, the inner wall of the abutting part 29 abuts against the outer wall of the buckle part 24. At this time, the support plate 22 is buckled with the box body 1, and no additional parts are required for buckling or welding, and the operation method is simple and easy to operate.

[0022] Preferably, an upper inclined surface 34 is provided at the end of the abutting part 29, the buckle part 24 is recessed, when the abutting part 29 moves upward, the upper inclined surface 34 abuts against the concave part, and a movable baffle 25 is further provided on the buckle part 24. The two sides of the movable baffle 25 are separated from the buckle part 24. The movable baffle 25 facilitates the insertion of the insertion part 28. Since the movable baffle 25 is separated from the buckle part 24, it is prevented that the insertion part 28 cannot extend out of the buckle opening 31 when the support plate 22 moves downward.

[0023] Preferably, a side groove 11 is recessed inward on the side surface of the support plate 22. The side groove 11 is located below the insertion part 28, and a lower inclined surface 35 is further provided at the lower end of the side groove 11. When the insertion part 28 is inserted into the buckle opening 31, the support plate 22 is moved upward, and the lower inclined surface 35 abuts against the inner wall of the buckle part 24, avoiding damage to the inner wall of the box body 1 caused by the sharp edges of the two when they are buckled with each other. The concave setting of the side groove 11 on the side of the box body 1 is convenient for matching the shape of the buckle part 24, preventing the support plate 22 from not being able to move downward and causing the protrusion to be unable to be installed. The lower inclined surface 35 can facilitate the outer wall not to cause damage to the inner wall of the box body 1 when sliding upward.

[0024] Preferably, a connecting plate 26 is transversely arranged at the upper end of the support plate 22. A bending is provided between the support plate 22 and the connecting plate 26. A screw hole 10 is formed in the connecting plate 26. A through hole adapted to the screw hole 10 is provided on the panel 2. A screw can penetrate through the through hole. When the screw passes through the through hole and is connected to the screw hole 10, it can drive the support plate 22 to move upward, preventing the support plate 22 from moving downward. In the previous screw method, screws were also required to be fixed on the upper, lower, left, and right sides of the box body 1 to prevent movement. Now, only one screw is needed to fix the support plate 22. When the screw is tightened, the support plate 22 will move upward with the rotation of the screw, thus clamping the box body 1 more stably. And the buckling part 24 is arranged in a concave shape. The shape of the inner wall of the box body 1 will be inward. Only when the support plate 22 moves downward can the insertion part 28 enter the buckling opening 31. Otherwise, if the length of the insertion part 28 just abuts against the inner wall of the box body 1, it cannot move upward. After the support plate 22 of the present invention moves downward, the insertion part 28 follows the inner wall of the box body 1 downward and gradually moves downward along the inner wall of the buckling part 24 arranged in a concave shape. At this time, the user only needs to move the insertion part 28 downward towards the movable baffle 25 to smoothly move downward, preventing it from being unable to move downward and thus unable to be inserted into the buckling opening 31.

[0025] The above embodiments are only the preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
