Description

Technical Field

[0001] This utility model relates to the field of bolt technology, and in particular to a bolt assembly for connecting anti-loosening wall panel grids. Background Technology

[0002] A bolt is a common fastener, usually made of metal, and is mainly used to connect two or more objects. It consists of two parts: a screw and a nut. The outer surface of the screw has threads, and the nut has corresponding threads inside. The bolt can be fixed to the object by rotation. When the bolt is tightly engaged with the nut or screw hole and tightened, the friction of the threads fixes the connected parts, providing sufficient tensile or compressive force to prevent the parts from loosening or shifting.

[0003] Grille connecting bolts are a type of bolt specifically designed for connecting grille panels. They are used in various engineering projects, such as buildings, bridges, or industrial facilities, where grille panels are used for ventilation, drainage, and load-bearing purposes. Grille connecting bolts are used to secure these grille panels to supporting structures or other components.

[0004] When installing grating connecting bolts, it is necessary to accurately control the bolt torque to ensure the proper tightness of the connection. Excessive torque can cause the bolts to stretch excessively or even break, while insufficient torque will prevent the bolts from providing enough tightening force, leading to loosening of the connection. The current solution is to use tools with high-precision torque wrenches, and operators who have received professional training to master the correct torque control methods and install the bolts according to the specified torque values. However, in some situations with high vibration, such as gratings on roads and bridges, and vibrating screens in industrial equipment, the grating connecting bolts will gradually loosen due to equipment vibration or external forces, causing the grating connection to become loose, resulting in gaps or shaking, which will affect the normal use of the grating. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides an anti-loosening wall panel grid connecting bolt assembly, which aims to improve the problem in the prior art where the grid connecting bolts gradually loosen due to equipment vibration or external force, causing the grid connection to become loose, resulting in gaps or shaking, which in turn affects the normal use of the grid.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: an anti-loosening wall panel grid connecting bolt assembly, including a locking rod, a fixing plate fixedly connected to the top of the outer wall of the locking rod, a rotating shaft rotatably connected to the left and right sides of the top wall of the fixing plate, a locking shell rotatably connected to the top of the rotating shaft, a locking groove provided on one side of the locking shell, the outer wall of the locking rod engaging with the locking groove, a sliding plate slidably connected to the front and rear ends of the left side of the locking shell, a connecting groove provided on the front and rear sides of the top wall of the right side of the locking shell, the right side of the sliding plate engaging with the connecting groove, a lock head fixedly connected to the top of the locking rod, and a maintenance mechanism provided on the top wall of the lock head, the maintenance mechanism being used to improve the maintenance operation of the bolt.

[0007] As a further description of the above technical solution:

[0008] The maintenance mechanism includes a rotating column, the bottom of which is rotatably connected to the right side of the top wall of the lock head, and a sealing cover is rotatably connected to the top of the rotating column. The top wall of the lock head has a corner groove, an injection groove in the middle of the top wall of the lock head, and diversion grooves on both the front and rear sides of the lock head. The top wall of the fixing plate has a passage groove on both the front and rear sides.

[0009] As a further description of the above technical solution:

[0010] Both sliding plates are fixedly connected to a locking plate on their left side. The left locking shell has two locking slots in the middle of its left side, and the right side of the locking plate engages with the locking slots.

[0011] As a further description of the above technical solution:

[0012] Multiple rubber rings are fixedly connected to the middle of the outer wall of the lock head, and the multiple rubber rings are arranged at equal intervals.

[0013] As a further description of the above technical solution:

[0014] Rubber pads are fixedly connected to both the left and right sides of the bottom wall of the fixing plate, and the rubber pads are square in shape.

[0015] As a further description of the above technical solution:

[0016] The bottom end of the locking rod is threadedly connected to a fastening shell, and the top of the fastening shell has multiple square slots.

[0017] As a further description of the above technical solution:

[0018] A protective disc is fixedly connected to the lower middle part of the outer wall of the lock head, and the outer wall of the protective disc has a smooth design.

[0019] As a further description of the above technical solution:

[0020] The diameter of the lock head is larger than the diameter of the lock rod, and the inner wall of the fastening shell matches the outer wall of the lock rod.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, after the locking rod is rotated and connected, the two locking shells are flipped so that the locking groove inside can engage with the outer wall of the locking rod. At the same time, the sliding plate is pushed so that its rear end engages with the corresponding connecting groove. Meanwhile, the locking plate engages with the locking groove to lock, which improves the fixing effect on the outer wall of the locking rod and avoids the connecting bolt from gradually loosening due to vibration, thereby improving the stability of the connecting bolt.

[0023] 2. In this utility model, by opening the sealing cover, the bolts in use can be maintained. Then, by injecting maintenance oil into the corner groove and the injection groove, the maintenance oil is displaced by gravity through the injection groove and the distribution groove, so that the maintenance oil can adhere to the outer wall of the locking rod through the distribution groove and the groove, thereby improving the service life of the bolt.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of an anti-loosening wall panel grid connecting bolt assembly, including a locking rod 1. A fixing plate 3 is fixedly connected to the top of the outer wall of the locking rod 1. A rotating shaft 4 is rotatably connected to the left and right sides of the top wall of the fixing plate 3, so that the locking shell 5 can be flipped under the connection of the rotating shaft 4. The top of the rotating shaft 4 is rotatably connected to the locking shell 5. A locking groove 6 is opened on one side of the locking shell 5. The outer wall of the locking rod 1 is engaged with the locking groove 6, so that the outer wall of the locking rod 1 can be locked under the rotation of the locking shell 5. The left front and rear ends of the left side of the left locking shell 5 are slidably connected to the sliding plate 7. The front and rear sides of the top wall of the right locking shell 5 are both provided with the connecting groove 10. The right side of the sliding plate 7 is engaged with the connecting groove 10, so that the right locking shell 5 can be connected and engaged under the sliding of the sliding plate 7, thereby improving the locking effect between the locking shells 5. A lock head 11 is fixedly connected to the top of the locking rod 1. A maintenance mechanism 2 is provided on the top wall of the lock head 11. The maintenance mechanism 2 is used to improve the maintenance operation of the bolt.

[0033] Specifically, by rotating the locking rod 1, the connection is completed. Then, by flipping the two locking shells 5, the engaging groove 6 inside the locking shell 5 is ensured to engage with the top of the outer wall of the locking rod 1, thus achieving initial locking of the locking rod 1. At the same time, the sliding plate 7 on the left side of the left locking shell 5 is pushed so that its right end engages with the connecting groove 10 on the left side of the right locking shell 5. In addition, the engagement and locking of the locking plate 8 and the locking groove 9 further enhances the stability of the outer wall of the locking rod 1, effectively avoiding the problem of the connecting bolts gradually loosening due to vibration, thereby significantly improving the stability of the connecting bolts during use.

[0034] Reference Figure 1 , Figure 2 and Figure 5The maintenance mechanism 2 includes a rotating column 205. The bottom of the rotating column 205 is rotatably connected to the right side of the top wall of the lock head 11. The top of the rotating column 205 is rotatably connected to a sealing cover 206. The sealing cover 206 allows the top of the lock head 11 to be closed and opened, thereby achieving the effect of protecting the top. The top wall of the lock head 11 is provided with a corner groove 201 and an injection groove 202 is provided in the middle of the top wall of the lock head 11. Maintenance oil is injected through the injection groove 202. The front and rear sides of the lock head 11 are provided with diversion grooves 203. The front and rear sides of the top wall of the fixing plate 3 are provided with through grooves 204. The outer wall of the lock rod 1 is maintained by the diversion groove 203 and the through groove 204.

[0035] Specifically, by flipping the sealing cover 206 upwards, the top of the lock head 11 is opened, allowing necessary maintenance and upkeep of the already fixed bolts. Maintenance oil is injected into the injection groove 202 through the corner groove 201. Using gravity, the maintenance oil naturally flows from the injection groove 202 to the distribution groove 203. As the maintenance oil flows, it passes through the distribution groove 203 and, through the opening of the groove 204, evenly covers the outer wall of the lock rod 1, ensuring that the maintenance oil fully adheres to the outer wall of the lock rod 1, thereby effectively improving the service life of the bolts.

[0036] Reference Figure 1 , Figure 2 and Figure 4 Locking plates 8 are fixedly connected to the left side of both sliding plates 7. Two locking grooves 9 are opened in the middle of the left side of the left locking shell 5. The right side of the locking plate 8 engages with the locking groove 9. Multiple rubber rings 13 are fixedly connected to the middle of the outer wall of the lock head 11. The multiple rubber rings 13 are arranged at equal intervals. Rubber pads 14 are fixedly connected to the left and right sides of the bottom wall of the fixed plate 3. The rubber pads 14 are square in shape.

[0037] Specifically, the locking plate 8 and the locking groove 9 are engaged to lock the position of the sliding plate 7, thus improving the fixing effect. The connection of multiple rubber rings 13 increases the static friction at the top of the lock head 11. The connection of the rubber pads 14 reduces damage to the bottom of the fixing plate 3.

[0038] Reference Figure 1 , Figure 2 and Figure 3 The bottom end of the locking rod 1 is threadedly connected to a fastening shell 15, and the top of the fastening shell 15 is provided with multiple square grooves 16; the lower middle end of the outer wall of the lock head 11 is fixedly connected to a protective plate 12, and the outer wall of the protective plate 12 is designed to be smooth; the diameter of the lock head 11 is larger than the diameter of the locking rod 1, and the inner wall of the fastening shell 15 matches the outer wall of the locking rod 1.

[0039] Specifically, the threaded connection of the fastening shell 15 allows for secondary fixation of its bottom end. Multiple square grooves 16 improve the toughness of the fastening shell 15. The protective disc 12 protects the outer wall of the locking rod 1. The matching of the inner wall of the fastening shell 15 with the outer wall of the locking rod 1 improves the smoothness of bidirectional fixation.

[0040] Working principle: When in use, the locking rod 1 is rotated to complete the connection. Then, by flipping the two locking shells 5, the engaging groove 6 inside the locking shell 5 can engage with the top of the outer wall of the locking rod 1, achieving the purpose of initially locking the locking rod 1. At the same time, the sliding plate 7 on the left side of the left locking shell 5 is pushed, so that its right end engages with the connecting groove 10 on the left side of the right locking shell 5. Meanwhile, the locking plate 8 engages with the locking groove 9, which improves the stability of the outer wall of the locking rod 1, thereby preventing the connecting bolt from gradually loosening due to vibration, thus improving the stability of the connecting bolt during use.

[0041] Furthermore, by flipping the sealing cover 206 upwards, the top of the lock head 11 is opened, allowing for the maintenance of the fixed bolts. The maintenance oil then enters the injection groove 202 through the corner groove 201. The maintenance oil flows through the injection groove 202 and the diversion groove 203 under the action of gravity. Thus, with the opening of the diversion groove 203 and the through groove 204, the maintenance oil adheres to the outer wall of the lock rod 1, thereby improving the service life of the bolts.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
