Technical Field
[0001] The utility model belongs to the technical field of locks, and particularly refers to an assembly 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 lock 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. Through the adjustment box, the anti-scratch piece arranged on the adjustment box can better adhere to the door frame, making the anti-scratch effect better. Therefore, an installation seat is also welded inside the box body for the adjustment box to be installed. However, the bolt box itself is relatively small in size. When workers weld and assemble, they need to carefully place the installation seat into the box body and observe the welding through the unobstructed area not blocked by their hands, resulting in extremely low efficiency. Manufacturers cannot quickly assemble a large number of bolt boxes. Therefore, there is a need for an assembly method that does not require welding and can install the adjustment box into the bolt box in a simple manner without affecting its use. Summary of the Invention
[0003] The purpose of the utility model is to provide an assembly method with a simple structure, which does not require welding and can install the adjustment box into the bolt box in a simple manner without affecting its use.
[0004] The purpose of the utility model is achieved as follows:
[0005] An assembly structure of a bolt box includes a box body embedded with a door frame and a panel covering the box body. A lock tongue groove for the lock tongue to extend into is opened on the panel. An adjustment box is arranged inside the box body. The adjustment box includes an adjustment seat and an adjustment plate movably arranged on the adjustment seat. A buckling part is arranged on the lower surface of the adjustment seat. A connection hole is opened on the box body. The adjustment seat is inserted into the connection hole through the buckling part and is clamped with the box body. The buckling part includes a plugging part and a limiting part. The limiting part is bent relative to the plugging part. When the plugging part is inserted into the connection hole, the lower surface of the adjustment seat abuts against the box body. By controlling the lateral movement of the adjustment seat, the limiting part moves synchronously. At this time, the upper surface of the limiting part abuts against the lower surface of the box body and restricts the adjustment seat from detaching.
[0006] Furthermore, a rear inclined surface is arranged at the rear end of the plugging part, and a front inclined surface is also arranged at the front end of the limiting part. A smooth transition part is formed by annularly arranging on the inner wall of the connection hole. When the plugging part is inserted into the connection hole, the rear inclined surface contacts the transition part of the connection hole. By controlling the lateral movement of the adjustment seat, the rear inclined surface disengages from the contact with the transition part, and the front inclined surface contacts the transition part of the connection hole. At this time, the upper surface of the limiting part abuts against the lower surface of the box body.
[0007] Further, a connecting plate is also provided upward on one side of the adjusting seat. The upper end of the connecting plate is transversely bent to form a bent portion, and a screw hole is formed in the bent portion. A through hole adapted to the screw hole is provided on the panel. A screw can pass through the through hole. When the screw passes through the through hole and is connected to the screw hole, the relative lateral movement of the adjusting seat with respect to the box body can be restricted.
[0008] Further, an eccentric adjusting member is also provided on the adjusting plate. The eccentric adjusting member is rotatably connected to the adjusting plate. The eccentric adjusting member includes a bit slot adapted to a screw tool and a spiral portion. The bit slot is provided on the upper surface of the adjusting plate, and the spiral portion is provided on the lower surface of the adjusting plate. A plurality of convex platforms are provided on the upper surface of the adjusting seat, and a track groove is formed between adjacent convex platforms. Driving the bit slot can drive the spiral portion to rotate on the track groove.
[0009] Further, a guide plate is also provided on the adjusting plate. A fixing portion is provided on the guide plate. A fixing hole is formed on the upper surface of the adjusting seat. The guide plate is fixed to the fixing hole through the fixing portion and is restricted from moving relative to the adjusting seat. A guide hole is formed on the upper surface of the guide plate, and the bit slot is provided in the guide hole.
[0010] The prominent and beneficial technical effects of the present utility model compared with the prior art are:
[0011] The present utility model is an assembly structure of a plug box. Compared with the connection method of the prior art, it is more convenient. It does not require workers to weld inside a narrow box body. It only needs to open a connection hole on the box body and a fastening portion on the lower surface of the adjusting seat. By bending the limiting portion and the inserting portion, the adjusting seat can be more firmly clamped with the box body. During installation, the inserting portion extends into the connection hole, and at this time, the limiting portion does not contact the box body. After controlling the lateral movement of the adjusting seat, the limiting portion synchronously moves to the lower surface of the box body. At this time, the adjusting seat is restricted by the force of the limiting portion against the box body and cannot move upward. It can be opened in batches by a machine. Workers only need to relatively clamp the two to assemble. It not only improves the production efficiency of the factory but also protects the physical health of workers without the need to contact chemical odors and keep staring at the welding area. The simple mutual buckling is not only convenient for installation but also for disassembly, preventing the need for overall replacement after damage. Moreover, the clamping method requires lower labor costs compared with welding or screw connection, is easy to operate, does not require extra time to learn welding technology, and it is easy to damage the inside of the box body during the welding process. And the screw will cause wear on the thread surface after being turned for a long time. The present utility model has a longer service life. Description of the Drawings

Specific embodiments
[0023] The present utility model will be further described below in conjunction with specific embodiments:
[0024] An assembly structure of a bolt box includes a box body 1 embedded in a door frame and a panel 2 covering the box body 1. A lock tongue groove 3 for the lock tongue to extend into is provided on the panel 2. An adjustment box is provided inside the box body 1. The adjustment box includes an adjustment base 4 and an adjustment plate 5 movably arranged on the adjustment base 4. A snap-in part 7 is provided on the lower surface of the adjustment base 4, and a connection hole 6 is provided on the box body 1. The adjustment base 4 is snapped into the box body 1 by inserting the snap-in part 7 into the connection hole 6. The snap-in part 7 includes a plug-in part 28 and a limiting part 29. The limiting part 29 is bent relative to the plug-in part 28. When the plug-in part 28 is inserted into the connection hole 6, the lower surface of the adjustment base 4 abuts against the box body 1. By controlling the lateral movement of the adjustment base 4, the limiting part 29 moves synchronously. At this time, the upper surface of the limiting part 29 abuts against the lower surface of the box body 1 and restricts the adjustment base 4 from detaching.
[0025] The utility model relates to an assembly structure of a plug box, which has a simpler connection method compared with the prior art. It does not require workers to weld inside the narrow box body 1. Only by opening a connection hole 6 on the box body 1 and a fastening part 7 on the lower surface of the adjusting seat 4, the adjusting seat 4 can be more firmly clamped with the box body 1 through the bent setting of the limiting part 29 and the inserting part 28. During installation, the inserting part 28 extends into the connection hole 6. At this time, the limiting part 29 does not contact the box body 1. After controlling the transverse movement of the adjusting seat 4, the limiting part 29 synchronously moves to the lower surface of the box body 1. At this time, the adjusting seat 4 is unable to move upward due to the force of the limiting part 29 against the box body 1. It can be batch-opened by a machine. Workers only need to relatively clamp the two to complete the assembly. This not only improves the production efficiency of the factory but also protects the physical health of workers, eliminating the need to contact chemical odors and constantly stare at the welding area. The simple mutual buckling is not only convenient for installation but also for disassembly, preventing the need for overall replacement after damage. Moreover, the clamping method requires lower labor costs compared with welding or screw 12 connection. It is easy to operate and does not require additional time to learn welding techniques. Also, the inside of the box body 1 is easily damaged during the welding process, and the thread surface wears after the screw 12 is rotated for a long time. The utility model has a longer service life.
[0026] Preferably, a rear inclined surface 31 is provided at the rear end of the inserting part 28, and a front inclined surface 30 is further provided at the front end of the limiting part 29. A smooth transition part is formed by annular molding on the inner wall of the connection hole 6. When the inserting part 28 is inserted into the connection hole 6, the rear inclined surface 31 contacts the transition part of the connection hole 6. By controlling the transverse movement of the adjusting seat 4, the rear inclined surface 31 disengages from the contact with the transition part, and the front inclined surface 30 contacts the transition part of the connection hole 6. At this time, the upper surface of the limiting part 29 abuts against the lower surface of the box body 1, so that when the inserting part 28 is inserted into the connection hole 6, no abnormal noise will be generated due to the sharpness of the two or the surface of the box body will not be scratched. After the inserting part 28 is inserted into the connection hole 6, the rear inclined surface 31 will slide forward after abutting against the transition surface of the connection hole 6. At this time, the front inclined surface 30 will not touch the transition part. Manually control the adjusting seat 4 to move forward, the front inclined surface 30 touches the transition part on the connection hole 6, and the rear inclined surface 31 disengages from the transition part, preventing the box body 1 from being scratched by the sharp edge during the movement of the front inclined surface 30.
[0027] Preferably, a connecting plate 8 is further provided upward on one side of the adjusting seat 4. The upper end of the connecting plate 8 is transversely bent to form a bent portion 9, and a screw hole 10 is formed in the bent portion 9. A through hole adapted to the screw hole 10 is provided on the panel 2. A screw 12 can be inserted into the through hole. When the screw 12 passes through the through hole and is connected to the screw hole 10, it can limit the lateral movement of the adjusting seat 4 relative to the box body 1. The bent portion 9 is threadedly connected to the panel 2 through the screw 12 to limit the lateral movement of the adjusting seat 4. In order to facilitate the insertion of the fastening portion 7 into the connection hole 6, the connection hole 6 is larger than the final length of the fastening portion 7. In the present invention, the up-and-down and front-and-back movements of the fastening portion 7 are restricted at two places respectively, so that the adjusting seat 4 can be more stably installed in the box body 1, and the restricting portion 29 is prevented from detaching from the lower surface of the box body 1 to the connection hole 6.
[0028] Preferably, an eccentric adjusting member 13 is further provided on the adjusting plate 5. The eccentric adjusting member 13 is rotatably connected to the adjusting plate 5. The eccentric adjusting member 13 includes a bit groove 14 adapted to the tool of the screw 12 and a spiral portion 15. The bit groove 14 is provided on the upper surface of the adjusting plate 5, and the spiral portion 15 is provided on the lower surface of the adjusting plate 5. A plurality of convex platforms 16 are provided on the upper surface of the adjusting seat 4, and a track groove is formed between adjacent convex platforms 16. Driving the bit groove 14 can drive the spiral portion 15 to rotate on the track groove, which is convenient for the user to use the adjustment, facilitates the user's fine adjustment, is beneficial to the tight connection between the locking tongue and the adjusting plate 5, and the user can control the sliding of the adjusting plate 5 by rotating the bit groove 14, which is convenient for the user to adjust and control.
[0029] Preferably, a guiding plate 18 is further provided on the adjusting plate 5. A fixing portion 19 is provided on the guiding plate 18.
