DETAILED DESCRIPTION

[0023] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0024] Example:

[0025] Reference Figure 1 - Figure 5 The utility model discloses a composite nylon wheel assembly, comprising an outer ring assembly 1, an inner ring assembly 2 and a plug-in assembly 3, wherein the plug-in assembly 3 is composed of a connecting seat 31, a connecting block 32, a support rod 33 and a positioning piece 34, wherein the inner side wall of the outer ring assembly 1 and the outer side wall of the inner ring assembly 2 are both provided with a plurality of groups of connecting seats 31 in an annular array, two groups of support rods 33 are provided between two corresponding connecting seats 31, both ends of the two support rods 33 are connected with a connecting block 32 inserted into the connecting seat 31, and the two support rods 33 are connected by a positioning piece 34.

[0026] In this embodiment, when in use, the inner ring assembly 2 and the outer ring assembly 1 are placed on the same plane, and then the connecting blocks 32 at both ends of the support rod 33 in the plug-in assembly 3 are aligned with the corresponding connecting seats 31, and then a lateral force is applied to the support rod 33 to press it into the connecting seat 31, and the connecting block 32 of the support rod 33 is inserted into the connecting seat 31 to complete the preliminary connection between the inner ring assembly 2 and the outer ring assembly 1, and finally all the support rods 33 are pressed into the corresponding connecting seats 31 in turn to complete the assembly of the nylon wheel.

[0027] When the nylon wheel is grinding the product, the contact between its surface and the product is uneven, resulting in an unstable force on the nylon wheel, which will cause the nylon wheel to vibrate due to the uneven force. As a result, the support rod 33 is pulled out of the connecting seat 31 with the connecting block 32 under the lateral force generated by the shaking, thereby causing the nylon wheel to disintegrate, affecting the use of the nylon wheel. Figure 2 It can be found that by fixing two adjacent support rods 33 using the positioning member 34, the lateral forces acting on the two support rods 33 are restrained from each other, thereby ensuring the installation stability of the support rods 33 and making the use of the nylon wheel safer.

[0028] Among them, the above-mentioned outer ring component 1 and inner ring component 2 are the same as the inner ring component and outer ring component disclosed in Chinese patent publication No. CN220279309U, and the present application adopts a group of connecting seats 31 connected to two support rods 33, and the two support rods 33 are connected by a positioning piece 34, so that when the nylon wheel shakes, the lateral forces exerted on the two support rods 33 are offset to ensure the connection stability of the nylon wheel, and the setting of the connecting component is omitted, so that the outer wall of the inner ring of the inner ring component 2 does not need to be processed with an external threaded body, which can effectively reduce the production difficulty of the inner ring component 2, thereby reducing the production cost of the nylon wheel, and further improving the practicality of the nylon wheel.

[0029] In a further preferred embodiment of the present invention, Figure 2 As shown, the outer side wall of the connecting seat 31 is provided with two slots 4 for fixing the connecting block 32 , and the slots 4 of two corresponding connecting seats 31 are symmetrically arranged.

[0030] In this embodiment, in order to make the connection between the inner ring assembly 2 and the outer ring assembly 1 more secure, two support rods 33 are provided. The lateral forces of the two support rods 33 are offset against each other to prevent the connecting block 32 from falling out of the connecting seat 31 when the nylon wheel vibrates. Therefore, the slots 4 of the two corresponding connecting seats 31 are symmetrically arranged, so that the support rods 33 installed between the two corresponding connecting seats 31 can be perpendicular to the surfaces of the inner ring assembly 2 and the outer ring assembly 1, which can effectively enhance the support of the support rods 33 to the inner ring assembly 2 and the outer ring assembly 1, thereby enhancing the use strength of the nylon wheel.

[0031] In a further preferred embodiment of the present invention, Figure 5 As shown, the two slots 4 are arranged in a circular array in the middle of the connecting seat 31 , so that one of the slots 4 is opened on the front side wall of the connecting seat 31 , and the other slot 4 is opened on the rear side wall of the connecting seat 31 .

[0032] In this embodiment, because the two support rods 33 are provided to offset the lateral force generated by the shaking of the nylon wheel to prevent the connecting block 32 from escaping from the connecting seat 31 and causing the nylon wheel to disintegrate during use, the movable directions of the two support rods 33 need to be opposite.

[0033] So observe Figure 5 It can be found that the two slots 4 on the connection seat 31 are arranged in a circular array with the middle of the connection seat 31 as the base point, so that the opening directions of the two slots 4 are opposite, so that the movable directions of the two connection blocks 32 inserted into the slots 4 are opposite. Through such an arrangement, when the two connection blocks 32 are subjected to lateral forces moving in the same direction, one of the connection blocks 32 will be blocked by the inner wall of the slot 4 and cannot move, while the other connection block 32 will also be unable to move under the restriction of the positioning member 34 and the support rod 33, so as to achieve a fixing effect. When the lateral forces are opposite, the two connection blocks 32 will also be unable to move for the same reason, which can effectively ensure the firmness of the connection between the inner ring component 2 and the outer ring component 1.

[0034] In a further preferred embodiment of the present invention, Figure 3 As shown, the positioning member 34 includes a positioning shaft 341, a ball 342 and a spring 343. A positioning groove 5 for connecting the positioning shaft 341 is provided in the middle of the outer wall of the support rod 33, and the positioning shaft 341 is slidably connected. The inner wall of the positioning groove 5 is provided with a plurality of groups of pressure grooves 6 in a circular array. Balls 342 are slidably provided in the pressure grooves 6. A spring 343 is fixedly connected between the ball 342 and the pressure groove 6. The outer wall of the positioning shaft 341 is provided with an annular groove 7 for clamping the ball 342.

[0035] In this embodiment, because the two support rods 33 are separated, a positioning shaft 341 is provided, and a positioning groove 5 is opened in the middle of the two support rods 33, so that when the positioning shaft 341 is inserted into the two positioning grooves 5, the two support rods 33 are connected by friction.

[0036] Because the ends of the two support rods 33 are restricted by the slots 4 of the connecting seat 31, the support rods 33 can only move toward the same side to be separated from the connecting seat 31, so that when the support rod 33 rotates around the axis of the positioning shaft 341, one of the connecting blocks 32 of the support rod 33 will be restricted by the inner wall of the slot 4 to prevent the support rod 33 from rotating. Because the installation directions of the two support rods 33 are opposite, a positioning shaft 341 is provided to stably connect the two support rods 33, which can reduce the production cost of the nylon wheel while ensuring the stable operation of the nylon wheel.

[0037] Because the positioning shaft 341 needs to be inserted into the positioning groove 5, there needs to be an assembly gap between the positioning shaft 341 and the positioning groove 5. Otherwise, the insertion difficulty of the positioning shaft 341 will increase, and the subsequent disassembly and replacement difficulty will also increase accordingly. Therefore, the control requirements for the assembly gap are very high, which will implicitly increase the production cost of the nylon wheel. Figure 3 It can be found that an annular groove 7 is opened on the outer wall of the positioning shaft 341, and a pressure groove 6 is opened in the positioning groove 5. The pressure groove 6 is connected with a ball 342 through a spring 343, so that when the positioning shaft 341 is inserted into the positioning groove 5, the ball 342 can be pressed into the pressure groove 6. Then, when the annular groove 7 and the pressure groove 6 coincide with each other, the ball 342 loses the squeezing of the positioning shaft 341 and is pushed out by the spring 343, so that the ball 342 can be stuck in the annular groove 7, which can be used to improve the installation firmness of the positioning shaft 341, and can also reduce the processing progress of the positioning shaft 341 and the positioning groove 5, which can reduce the difficulty of connecting the two support rods 33 and reduce the processing cost.

[0038] In a further preferred embodiment of the present invention, Figure 3 As shown, the length of the positioning shaft 341 is equal to the sum of the thicknesses of the two support rods 33 , and the annular groove 7 on the outer wall of the positioning shaft 341 is provided with two groups, which are respectively used to clamp the balls 342 in the two support rods 33 .

[0039] In this embodiment, because the positioning shaft 341 needs to connect the two support rods 33, the length of the positioning shaft 341 must be kept the same as the thickness of the two support rods 33 stacked together, so as to reduce the difficulty of disassembly of the positioning shaft 341 after installation. Because the two support rods 33 clamp the positioning shaft 341 through the ball bearings 342 to achieve the connection effect, two sets of annular grooves 7 are provided on the outer wall of the positioning shaft 341 to ensure the stability of the connection.

[0040] In a further preferred embodiment of the present invention, Figure 4 As shown, the diameter of the inner wall of the pressure groove 6 near the opening gradually decreases from the inside to the outside to form a closing portion 8 for blocking the ball 342.

[0041] In this embodiment, because the ball 342 is fixed to the positioning shaft 341 and is also restricted by the positioning shaft 341 and cannot further escape from the pressure groove 6, when the positioning shaft 341 is not inserted into the positioning groove 5, the ball 342 will escape from the pressure groove 6 under the push of the spring 343, thereby increasing the difficulty of installing the nylon wheel. Figure 4 It can be found that the inner diameter of the opening of the pressure groove 6 is reduced to form a closing portion 8. The closing portion 8 can be used to block the ball 342, which can effectively prevent the ball 342 from escaping from the pressure groove, thereby reducing the difficulty of assembling the nylon wheel.

[0042] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
