Description

Technical Field

[0001] This utility model relates to the field of belt pulley technology, and in particular to a detachable belt pulley structure. Background Technology

[0002] Belt pulleys, belonging to the category of disc-hub parts, are generally relatively large in size. In terms of manufacturing processes, they are mainly cast or forged. Larger ones are usually designed to be cast using cast iron (which has better casting properties) and rarely cast steel (which has poor casting properties). Smaller ones can be designed to be forged using steel. Belt pulleys are mainly used for long-distance power transmission and have a wide range of applications in various industries.

[0003] In a pulley structure with announcement number CN212839266U, a pulley shaft and a pulley baffle are included. One end of the pulley shaft passes through the wheel hole of the pulley and is fixedly connected to the baffle. An adjusting bolt is provided on the baffle, which passes through the baffle and the pulley and is threadedly connected to the baffle and the pulley. The position of the pulley on the pulley shaft can be adjusted by using the baffle and the adjusting bolt, making the adjustment process simple and quick and preventing the operation from being affected by the difficulty of adjusting the pulley.

[0004] However, the existing pulley structure still has the following drawbacks in use: the existing technology uses bolts and nuts with the help of tools to install and fix the pulley and pulley shaft. However, in actual use, the above operation is inconvenient for quick disassembly and assembly of the pulley, thus reducing the efficiency of pulley disassembly and assembly. Utility Model Content

[0005] The purpose of this utility model is to provide a detachable pulley structure to solve the problem mentioned in the background art that the existing pulley structure is not convenient to disassemble and assemble quickly during use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a detachable pulley structure, including a right wheel, a left wheel, and a rotating shaft, wherein the left wheel is provided on one side of the right wheel, and the rotating shaft passes through the interior of the right wheel and the left wheel;

[0007] Guide blocks are fixed on both sides inside the left wheel, and each guide block is equipped with a disassembly and assembly mechanism. Four fixing rods are fixed on one side of the left wheel, and each fixing rod is equipped with a limit mechanism. Guide grooves are opened on both sides of the rotating shaft.

[0008] When using a detachable pulley structure based on this technical solution, the right and left pulleys can be quickly disassembled and assembled from the rotating shaft by means of a disassembly and assembly mechanism under the action of guide grooves and guide blocks, thereby improving the efficiency of disassembly and assembly.

[0009] Furthermore, the limiting mechanism includes a storage groove, which is located inside the fixed rod. Two sliding blocks are slidably arranged inside the storage groove, and a stop bar is fixed on one side of each sliding block. A return spring is provided inside the storage groove, and both ends of the return spring are fixedly connected to the sliding blocks respectively.

[0010] Furthermore, the stop levers are provided in four groups, with two stop levers in each group, and the stop levers in each group are symmetrically distributed.

[0011] Furthermore, four reset springs are provided, and all four reset springs are in a stretched state inside the receiving groove.

[0012] Furthermore, the disassembly and assembly mechanism includes a fixing block, which is disposed inside the guide block. A baffle is slidably disposed inside the fixing block, and a fixing spring is fixed on one side of the baffle. A limit rod is welded to the other side of the baffle, and a push rod is disposed on the front side of the baffle.

[0013] Furthermore, there are two limiting rods, which are symmetrically distributed, and each of the two limiting rods has a disassembly hole on the outer side of one end, which is located inside the rotating shaft.

[0014] Furthermore, two baffles are provided, both of which have circular cross-sections, and the outer edges of both baffles are slidably attached to the inner wall of the fixing block.

[0015] Furthermore, four fixing rods are provided, arranged in a cross shape, and each of the four fixing rods has a fixing groove on its outer side, which is opened inside the right wheel.

[0016] Compared with the prior art, the beneficial effects of this utility model are: the detachable pulley structure can not only be quickly disassembled and assembled, but also achieves the effect of individual disassembly and assembly;

[0017] By pushing the right and left wheels, the rotating shaft is inserted into the inside of the right and left wheels, thereby causing the guide block to be inserted into the inside of the guide groove. During the insertion process, the push rod is pushed under the action of the baffle, causing the limiting rod to be retracted into the inside of the fixed block. After the guide block moves a certain position inside the guide groove, the force of the fixed spring being squeezed disappears, thereby pushing the baffle to move horizontally, and then causing the limiting rod to be inserted into the disassembly hole. The above operation facilitates the quick disassembly and assembly of the right and left wheels, thereby improving the efficiency of disassembly and assembly.

[0018] By squeezing the two levers, the levers are retracted into the storage slot, which facilitates the release of the right wheel's restriction and allows for its separate disassembly. The above-mentioned simultaneous operations facilitate the installation of the right wheel. Through these operations, the right and left wheels can be easily disassembled and assembled, thereby improving its practicality. Attached Figure Description

Detailed Implementation

[0026] 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.

[0027] Please see Figures 1-5The present invention provides an embodiment of a detachable pulley structure, including a right wheel 1, a left wheel 2, and a rotating shaft 3. The left wheel 2 is provided on one side of the right wheel 1. The rotating shaft 3 passes through the interior of the right wheel 1 and the left wheel 2. Guide blocks 7 are fixed on both sides inside the left wheel 2, and each guide block 7 is provided with a disassembly and assembly mechanism 8.

[0028] The disassembly and assembly mechanism 8 includes a fixing block 805, which is located inside the guide block 7. A baffle 804 is slidably arranged inside the fixing block 805. A fixing spring 803 is fixed on one side of the baffle 804, and a limit rod 801 is welded to the other side of the baffle 804. A push rod 802 is provided on the front side of the baffle 804.

[0029] There are two limit rods 801, which are symmetrically distributed. Each of the two limit rods 801 has a disassembly hole on the outer side of one end, and the disassembly holes are opened inside the rotating shaft 3.

[0030] There are two baffles 804, both of which have circular cross-sections, and the outer edges of both baffles 804 slide against the inner wall of the fixing block 805.

[0031] Specifically, such as Figure 2 , Figure 3 , Figure 4 As shown, during use, the fixed spring 803 resets and pushes the baffle 804 to move horizontally, thereby causing the limit rod 801 to be inserted into the disassembly hole. The above operation facilitates the quick disassembly and assembly of the right wheel 1 and the left wheel 2, thereby improving its practicality.

[0032] Four fixing rods 5 are fixed on one side of the left wheel 2;

[0033] There are four fixing rods 5, which are arranged in a cross shape. Each of the four fixing rods 5 has a fixing groove on its outer side, and the fixing groove is opened inside the right wheel 1.

[0034] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown, when in use, the four fixed rods 5 ensure balanced force distribution and prevent stress concentration at a single point.

[0035] Furthermore, each of the fixed rods 5 is equipped with a limit mechanism 6 inside;

[0036] The limiting mechanism 6 includes a storage groove 602, which is located inside the fixed rod 5. Two sliding blocks 604 are slidably arranged inside the storage groove 602, and a stop bar 601 is fixed on one side of each sliding block 604. A return spring 603 is provided inside the storage groove 602, and both ends of the return spring 603 are fixedly connected to the sliding block 604 respectively.

[0037] There are four sets of stop levers 601, with two stop levers 601 in each set, and the stop levers 601 in each set are symmetrically distributed.

[0038] Four return springs 603 are provided, and all four return springs 603 are in a stretched state inside the storage groove 602.

[0039] Guide grooves 4 are provided on both sides of the rotating shaft 3.

[0040] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown, in use, by squeezing the two levers 601, the levers 601 are retracted into the storage slot 602, allowing the right wheel 1 and the left wheel 2 to be disassembled and assembled separately, thereby improving its flexibility.

[0041] Working Principle: In use, this invention first inserts the rotating shaft 3 into the right wheel 1 and left wheel 2 by pushing it, thereby inserting the guide block 7 into the guide groove 4. During insertion, the push rod 802 is pushed, causing the baffle 804 to move horizontally. Simultaneously, the baffle 804 compresses the fixing spring 803, while also driving the limiting rod 801 to move horizontally, causing it to retract into the fixing block 805. As the rotating shaft 3 is continuously pushed, the disassembly hole moves to the limiting rod 801. This causes the force of compression on the fixed spring 803 to disappear, which in turn pushes the baffle 804 to move horizontally. As the baffle 804 moves horizontally, it also pushes the limiting rod 801 to move horizontally until the limiting rod 801 is inserted into the disassembly hole. This facilitates the limiting of the rotating shaft 3. The above operation makes it easy to quickly fix the right wheel 1 and the left wheel 2 on the rotating shaft 3. Furthermore, by pushing the push rod 802 under the action of the baffle 804, the limiting rod 801 is retracted into the fixing block 805, allowing the right wheel 1 and the left wheel 2 to be disassembled. The above operation facilitates the quick disassembly and assembly of the right wheel 1 and the left wheel 2 from the rotating shaft 3, thereby improving the efficiency of disassembly and assembly.

[0042] Then, when it is necessary to disassemble the right wheel 1 and the left wheel 2 separately, by pressing the two levers 601, the two levers 601 move horizontally relative to each other, which in turn causes the two sliding blocks 604 to move horizontally relative to each other synchronously. The movement of the sliding blocks 604 presses the return spring 603, which is then compressed by the compressing force until the levers 601 are retracted into the storage groove 602. The above operation facilitates the release of the restriction on the right wheel 1, thereby facilitating the separate disassembly and replacement of the right wheel 1 and the left wheel 2 according to the actual use, reducing its usage cost. At the same time, the above synchronous operation can be performed to install them, thereby improving their practicality.
