Description

Technical Field

[0001] This utility model relates to the technical field of belt pulley auxiliary devices, and in particular to a belt pulley anti-loosening fixing device with a positioning component. Background Technology

[0002] A pulley is a type of disc-shaped part. The overall stability of the pulley's operation requires the use of corresponding auxiliary structures or devices. Therefore, anti-loosening and fixing devices are needed to improve the stability and service life of the pulley.

[0003] A pulley anti-loosening fixing device with announcement number CN222559100U includes a pulley body, a positioning gear, and a fixed rotating shaft. The positioning gear is rotatably connected to the inner side of the pulley body, and a rotating gear is rotatably connected to the outer side of the positioning gear away from the pulley body. A connecting shaft is fixedly inserted into the middle of the side wall of the positioning gear, and a positioning disc is fixedly connected to the end of the connecting shaft away from the positioning gear. In this utility model, the rotation of the positioning gear drives the rotation of the positioning disc through the connecting shaft, which in turn drives the rotation of the fixed rotating shaft through the positioning connecting belt. Furthermore, a positioning pin is provided on the fixed rotating shaft to improve the overall stability of the pulley. At the same time, the locking piece located on the side of the positioning gear can prevent the gear from disengaging from the gear groove during high-speed rotation, thus enhancing the overall safety and stability of the pulley.

[0004] However, the existing pulley anti-loosening fixing device still has the following defects in use: When the above-mentioned existing technology is used, the drive connecting belt is movably sleeved in the inner cavity of the groove on the outside of the wheel body. However, in actual use, the above operation is inconvenient to position the drive connecting belt, which makes it easy for it to loosen or shift due to vibration or impact during use, thereby affecting subsequent operations. Utility Model Content

[0005] The purpose of this utility model is to provide a pulley anti-loosening fixing device with a positioning component, so as to solve the problem mentioned in the background art that the existing pulley anti-loosening fixing device does not have a positioning function when in use.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a pulley anti-loosening fixing device with a positioning component, comprising a pulley body, a rotating shaft, a frame, and a connecting belt, wherein the rotating shaft passes through the interior of the pulley body, and the connecting belt is sleeved on the outer side of the pulley body, and a frame is provided on both sides of the pulley body;

[0007] The top of the frame is provided with a limiting plate, and the bottom of the limiting plate is provided with a positioning mechanism. Grooves are provided on both sides of the limiting plate, and fixing blocks are fixed on both sides of the bottom of the limiting plate. The fixing blocks are provided with a limiting mechanism inside.

[0008] When using the pulley anti-loosening fixing device with positioning component according to this technical solution, the positioning mechanism facilitates the positioning of the connecting belt on the pulley body during use, thereby preventing it from becoming loose or shifting in position, and thus improving its practicality.

[0009] Furthermore, the limiting mechanism includes a mounting block, which is disposed inside the fixed block. A return spring is fixed inside the mounting block, and a sliding block is disposed on one side of the return spring. A limiting rod is welded to one side of the sliding block.

[0010] Furthermore, two sliding blocks are provided, both of which have circular cross-sections, and the outer edges of both sliding blocks are slidably fitted against the inner wall of the mounting block.

[0011] Furthermore, two reset springs are provided, which are symmetrically distributed and are both in a stretched state inside the mounting block.

[0012] Furthermore, the positioning mechanism includes a fixed column, which is located at the bottom of the limiting plate. A damping block is adhered to the inner wall of the fixed column by adhesive. A compression spring is fixed inside the fixed column, and a baffle is fixed to the bottom of the compression spring. A telescopic column is provided at the bottom of the baffle, and a movable block is welded to the bottom of the telescopic column. A roller is rotatably connected to the bottom of the movable block.

[0013] Furthermore, the roller has a circular cross-section, the inside of the roller is made of aluminum, and the outside of the roller is wrapped with a protective layer made of Teflon.

[0014] Furthermore, the compression spring is in a stretched state inside the fixed column, and the compression spring is made of stainless steel.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the pulley anti-loosening fixing device with positioning component not only has a positioning function, but also a limiting function;

[0016] By squeezing the spring to generate a downward force, the baffle moves downward, and under the action of the telescopic column, the moving block moves downward synchronously, so that one side of the roller is in close contact with the side of the connecting belt. Through the above operation, the connecting belt can be positioned to compensate for the slack caused by the stretching or vibration of the connecting belt, avoid slippage or derailment, and thus improve its safety during use.

[0017] By pushing the limiting plate, the fixing block is inserted into the frame. By squeezing the limiting rod, the limiting rod is retracted into the mounting block until one side of the limiting plate and one side of the frame are in contact with each other. Then, under the action of the return spring and the sliding block, the limiting rod is pushed out from the mounting block. The above operation makes it easy to fix the limiting plate on the outside of the connecting belt, thereby limiting the connecting belt and preventing it from moving in position, thus improving its stability during use.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Please see Figures 1-5 An embodiment of this utility model is provided: a pulley anti-loosening fixing device with positioning components, including a pulley body 1, a rotating shaft 2, a frame 3, and a connecting belt 5. The rotating shaft 2 passes through the inside of the pulley body 1, and the connecting belt 5 is sleeved on the outside of the pulley body 1. A frame 3 is provided on both sides of the pulley body 1. A limit plate 7 is provided at the top of the frame 3, and a positioning mechanism 8 is provided at the bottom of the limit plate 7.

[0027] The positioning mechanism 8 includes a fixed column 801, which is located at the bottom of the limiting plate 7. A damping block 806 is attached to the inner wall of the fixed column 801 with glue. A compression spring 807 is fixed inside the fixed column 801. A baffle 805 is fixed at the bottom of the compression spring 807. A telescopic column 802 is located at the bottom of the baffle 805. A movable block 803 is welded to the bottom of the telescopic column 802. A roller 804 is rotatably connected to the bottom of the movable block 803.

[0028] The roller 804 has a circular cross-section. The inside of the roller 804 is made of aluminum, and the outside of the roller 804 is wrapped with a protective layer made of Teflon.

[0029] The compression spring 807 is in a stretched state inside the fixed post 801, and the compression spring 807 is made of stainless steel.

[0030] Specifically, such as Figure 1 , Figure 3 , Figure 4 As shown, during use, the compression spring 807 resets and pushes the baffle 805 to move downward. Under the action of the telescopic column 802 and the moving block 803, the roller 804 and the connecting belt 5 are made to fit together, which facilitates the positioning of the connecting belt 5 and prevents it from becoming loose or falling off during use.

[0031] The limiting plate 7 has grooves 9 on both sides, and fixing blocks 4 are fixed on both sides of the bottom end of the limiting plate 7, and the fixing blocks 4 are equipped with limiting mechanisms 6 inside.

[0032] The limiting mechanism 6 includes a mounting block 604, which is located inside the fixed block 4. A return spring 603 is fixed inside the mounting block 604, and a sliding block 602 is provided on one side of the return spring 603. A limiting rod 601 is welded to one side of the sliding block 602.

[0033] Two sliding blocks 602 are provided. The cross-section of both sliding blocks 602 is circular, and the outer edges of both sliding blocks 602 slide against the inner wall of the mounting block 604.

[0034] There are two reset springs 603, which are symmetrically distributed and are both in a stretched state inside the mounting block 604.

[0035] Specifically, such as Figure 1 , Figure 2 , Figure 5 As shown, during use, the reset spring 603 pushes the sliding block 602 to move horizontally, which facilitates the push of the limiting rod 601 out of the mounting block 604, thereby facilitating the limiting of the fixing block 4, and further facilitating the fixing of the limiting plate 7 to the outside of the connecting belt 5. The above operation facilitates the limiting of the connecting belt 5 and prevents the connecting belt 5 from shifting in position during use.

[0036] Working principle: When using this utility model, firstly, by pushing the limiting plate 7, the fixing block 4 is inserted into the inside of the frame 3. During the insertion process, the limiting rod 601 is squeezed, causing the sliding block 602 to move horizontally. At the same time, the sliding block 602 squeezes the return spring 603, causing the return spring 603 to be compressed by the squeezing force. Then, the limiting rod 601 is retracted into the mounting block 604 until one side of the limiting plate 7 and one side of the frame 3 are in contact with each other, causing the squeezing force on the return spring 603 to disappear, thereby pushing the sliding block 602 to move horizontally, and then causing the limiting rod 601 to move horizontally. Through the above operation, it is easy to push the limiting rod 601 out of the mounting block 604, thereby facilitating the limiting of the fixing block 4, and then facilitating the fixing of the limiting plate 7 on the frame 3, thereby facilitating the limiting of the pulley body 1, preventing the pulley body 1 from shifting position during use, and thus improving its stability during use.

[0037] Then, by resetting the compression spring 807, the baffle 805 moves downward. Simultaneously, the telescopic column 802 moves downward, pushing the moving block 803 downward. This causes one side of the roller 804 and the non-transmission surface of the connecting belt 5 to come into contact. Since the outer side of the roller 804 is covered with a protective layer, friction on the connecting belt 5 can be reduced when it is squeezed and positioned, thereby improving the service life of the connecting belt 5. The above operation can position the connecting belt 5, thereby preventing it from becoming loose and improving its safety during use. Furthermore, the damping block 806 can absorb the high-frequency vibration of the compression spring 807, preventing the roller 804 from swaying during use, thus improving its practicality.
