Description

Technical Field

[0001] This utility model belongs to the field of vehicle accessory technology, and specifically relates to a rotary lock. Background Art

[0002] Rotary locks are a common type of mechanical locking device. The design principle of rotary locks is to lock or unlock two parts by rotating them, ensuring that items are securely and reliably fixed together during transportation or use. Rotary locks are particularly common in vehicle accessories.

[0003] Existing rotary locks work by inserting the rotating part of the rotary lock into the locking part and rotating the rotating part. The connection and fixation between the rotating part and the locking part are achieved through the threaded groove and thread between the rotating part and the locking part, as well as the cooperation of a magnet. However, in actual use, when the rotary lock is subjected to a large tensile force, it is difficult to ensure that the rotary lock can withstand the large tensile force without loosening, which makes the locking performance of the rotary lock poor when subjected to a large tensile force. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a rotary lock. Through the cooperation of threads and threaded grooves with locking blocks and locking grooves, the rotating part can be quickly connected to the locking part while ensuring the strength of the connection. It can withstand large tensile forces without loosening, thus ensuring the safety of the items.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a rotary lock, including a base, a locking component is provided in the mounting groove opened in the middle of the upper surface of the base, a rotating component is provided at the upper end of the locking component, a groove is provided on the upper surface of the rotating component, a connecting ring is provided at the inner top of the rotating component, a thread is provided on the upper side of the outer arc surface of the connecting ring, a threaded groove that mates with the thread is opened on the upper side of the inner wall of the locking component, and a locking module for locking connection is also provided between the locking component and the rotating component.

[0006] As a further improvement of this utility model, the locking module includes supports evenly distributed inside the bottom of the locking component. Movable columns are slidably arranged in the middle of each support. Locking blocks are provided at the ends of the movable columns away from the vertical center of the locking component. Multiple evenly distributed locking grooves are provided on the lower outer surface of the connecting ring. A driving unit for moving the movable columns is also provided between the locking component and the rotating component. The driving unit includes a slide cylinder located in the middle of the bottom of the locking component. A sliding column is slidably arranged inside the slide cylinder. A pressing plate is provided at the top of the sliding column. Multiple evenly distributed connecting rods are rotatably arranged on the lower surface of the pressing plate. The connecting rods are rotatably connected to adjacent movable columns. A pressing column is provided in the middle of the top of the rotating component. A reset component for resetting the movable columns is also provided on the locking component. The locking blocks are installed in conjunction with adjacent locking grooves, and the pressing columns are installed in conjunction with the pressing plate. Rubber pads are provided on the upper surface of the pressing plate and the bottom of the pressing column.

[0007] As a further improvement of this utility model, the reset assembly includes a reset spring 1 disposed between the locking member and the pressing plate, the reset spring 2 being sleeved on the outer side of the slide cylinder and the slide column as a whole, and a fixing plate being provided on the side of the movable column near the vertical center of the locking member, and a reset spring 2 being disposed between the fixing plate and the adjacent support, the reset spring 2 being sleeved on the outer side of the movable column.

[0008] As a further improvement of this utility model, both the locking component and the rotating component are provided with an anti-corrosion coating on their outer sides.

[0009] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0010] Firstly, the rotating component is placed on the upper side of the locking component. Rotating the rotating component causes the connecting ring inside it to rotate. Then, through the engagement of the thread on the outer side of the connecting ring and the threaded groove on the upper side of the inner wall of the locking component, the rotating component and the locking component move closer together and connect.

[0011] Secondly, during the downward movement of the rotating part, the pressing column set in the middle of its bottom end moves downward, causing the pressing plate to slide between the movable column and the support through the connecting rod. At this time, the first and second return springs are compressed, and the movable column drives the locking block to insert into the inside of the locking groove and move in the locking groove. When the rotating part is fully inserted into the locking part, the locking block abuts against the inner wall of the locking groove.

[0012] Thirdly, the combination of threads and threaded grooves with locking blocks and locking grooves allows for quick connection between the rotating parts and the locking parts while ensuring the strength of the connection. This allows the parts to withstand greater tension without loosening, thus ensuring the safety of the items.

[0013] Fourth, the anti-corrosion coating on the outside of the locking and rotating parts can effectively prevent damage to the locking and rotating parts and can effectively improve their service life during daily use. Attached Figure Description

However, it is obvious to those skilled in the art that the present invention can be practiced without one or more of these details.

[0021] like Figure 1 , 2 As shown in Figure 3, the device includes a base 101. A mounting groove is provided in the middle of the upper surface of the base 101, and a locking member 102 is provided in the groove. A rotating member 103 is provided at the upper end of the locking member 102. A groove 104 is provided on the upper surface of the rotating member 103. A connecting ring 105 is provided at the top of the inner part of the rotating member 103. A thread 107 is provided on the upper side of the outer arc surface of the connecting ring 105. A threaded groove 106 that mates with the thread 107 is provided on the upper side of the inner wall of the locking member 102. A locking module for locking connection is also provided between the locking member 102 and the rotating member 103.

[0022] like Figure 2 , 3As shown in Figure 4, the locking module includes supports 201 evenly distributed at the bottom of the locking member 102. Movable columns 202 are slidably disposed in the middle of each support 201. Locking blocks 203 are disposed at the ends of the movable columns 202 away from the vertical center of the locking member 102. Multiple evenly distributed locking grooves 204 are opened at the lower end of the outer surface of the connecting ring 105. A driving unit for moving the movable columns 202 is also provided between the locking member 102 and the rotating member 103. The driving unit includes a slide cylinder 206 disposed in the middle of the bottom of the locking member 102. A slide column 207 is slidably disposed inside the slide cylinder 206. A pressing plate 208 is disposed at the top of the slide column 207. Multiple evenly distributed connecting rods 209 are rotatably disposed on the lower surface of the pressing plate 208. The connecting rods 209 are rotatably connected to adjacent movable columns 202. Next, a pressing post 205 is provided at the center of the top of the rotating part 103, and a reset assembly for driving the movable post 202 to reset is also provided on the locking part 102; the locking block 203 is installed in cooperation with the adjacent locking groove 204, and the pressing post 205 is installed in cooperation with the pressing plate 208; the reset assembly includes a reset spring 210 disposed between the locking part 102 and the pressing plate 208, the reset spring 210 is sleeved on the outer side of the slide cylinder 206 and the slide post 207 forming a whole, and a fixing plate 211 is provided on the side of the movable post 202 near the vertical center of the locking part 102, and a reset spring 212 is disposed between the fixing plate 211 and the adjacent support 201, and the reset spring 212 is sleeved on the outer side of the movable post 202; the diameter of the locking block 203 is smaller than the inner diameter of the locking groove 204.

[0023] like Figure 2 , 3 As shown in Figure 4, rubber pads are provided on the upper surface of the pressing plate 208 and the bottom end of the pressing column 205.

[0024] In use, the rotating component 103 is placed on the upper side of the locking component 102. Rotating the rotating component 103 causes the connecting ring 105 inside it to rotate. This, in turn, engages with the threaded groove 106 on the upper inner wall of the locking component 102 through the threaded thread 107 on the outer side of the connecting ring 105, causing the rotating component 103 and the locking component 102 to move towards each other. The rotating component 103 also causes the connecting ring 105 inside it to move deeper into the locking component 102. During this downward movement, the rotating component 103 causes the pressing column 205 at its lower center to move downward. This pressing column 205 presses down on the pressing plate 208, causing the pressing plate 208 to slide the sliding column 207 into the sliding cylinder 206. At this time, the pressing plate 208 rotates with the connecting rod 209, and the connecting rod 209 rotates with the movable column. Rotation occurs between 202, causing the pressing plate 208 to slide between the movable column 202 and the support 201 via the connecting rod 209. At this time, the return spring 1 210 and the return spring 212 are compressed, which in turn causes the movable column 202 inside the locking member 102 to move away from the vertical center of the locking member 102. As the rotating member 103 rotates and moves downward, the movable column 202 drives the locking block 203 to insert into the locking groove 204 and move within the locking groove 204. When the rotating member 103 is fully inserted into the locking member 102, the locking block 203 abuts against the inner wall of the locking groove 204. Through the cooperation of the thread 107 and the thread groove 106, and the cooperation of the locking block 203 and the locking groove 204, the rotating member 103 can be quickly connected to the locking member 102 while ensuring the strength of the connection. It can withstand a large pulling force without loosening, ensuring the safety of the item.

[0025] According to another embodiment of the present invention, such as Figure 1 , 2 As shown in Figure 3, both the locking element 102 and the rotating element 103 have an anti-corrosion coating on their outer surfaces. During daily use, the anti-corrosion coating on the outer surfaces of the locking element 102 and the rotating element 103 effectively prevents damage to them, thus extending their service life.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
