They are all analogous to the normal directions of the components in the modular combined rope pulley. They are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the utility model.

For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0040] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0041] Example:

[0042] like Figure 1 As shown, an embodiment of the present application discloses a modular combined rope pulley, which has the advantages of both the rigidity of a steel wheel and the softness of a nylon wheel. The specific structure includes: an outer ring sleeve 1, a nylon wheel rim 2, two wheel bodies 3 and multiple support members 4.

[0043] like Figure 3 As shown, the outer ring sleeve 1 is a circular tubular structure, and the outer peripheral surface has a positioning convex ring 11 extending radially outward; during installation, it is interference fitted on the outer ring of the bearing, which facilitates the replacement of the bearing.

[0044] like Figure 6 As shown, the outer peripheral surface of the nylon wheel 2 is provided with a plurality of rope grooves 21, which are in an annular structure and are arranged concentrically with the outer ring sleeve 1; the plurality of rope grooves 21 are arranged at intervals along the axial direction, and in this embodiment, there are six rope grooves, but not limited to this, and no specific limitation is made.

[0045] like Figure 2 As shown, two wheel bodies 3 are relatively installed on the outer ring sleeve 1, and are relatively arranged on the left and right sides to provide limited support for the nylon wheel rim 2.

[0046] Specifically, the wheel body 3 includes: a support plate 31 and a limit member 32; the support plate 31 is sleeved on the outer ring sleeve 1 and abuts against the side of the positioning protruding ring 11; the support plate 31 is a disc-shaped structure, and a circular hole is opened in the center for sleeve connection with the outer ring sleeve 1; the limit member 32 is fixedly sleeved on the support plate 31.

[0047] Among them, Figure 2 As shown, the two limiting members 32 can be assembled together to form an annular groove 32a for installing the nylon rim 2; during assembly, the two limiting members 32 are assembled toward each other on both sides of the nylon rim 2, so that the nylon rim 2 can be installed in the annular groove 32a formed by the assembly.

[0048] like Figure 2 As shown, a plurality of support members 4 are evenly distributed circumferentially between the two support plates 31 and are spaced apart around the outer ring tube sleeve 1; they are used to connect the two support plates 31 to improve the structural stability and increase the impact resistance; in this embodiment, six support members are arranged and evenly distributed, but are not limited to this, and may be five, seven or other, without specific limitation.

[0049] During assembly, after completing the combined assembly of the outer ring sleeve 1, the nylon rim 2, the two support plates 31, the two limit members 32 and the multiple support members 4, welding and fixing are performed at the gaps between the outer ring sleeve 1, the two support plates 31, the two limit members 32 and the multiple support members 4 so that the above components form an integral structure, thereby stably supporting the nylon rim 2.

[0050] The utility model can provide left and right limited support for the nylon wheel rim 2 through the above-mentioned structural design. The structure has high stability, strong impact resistance, easy bearing replacement, and convenient later maintenance. In addition, through modular combination, the production cost is reduced, the production efficiency is improved, and it is convenient for practical application.

[0051] In some embodiments, Figure 5 As shown, the limiting member 32 is further designed to be an integrally formed member, including: a support tube 321 and a side baffle 322 .

[0052] Specifically, the trustee 321 is a circular tube structure, which is mounted on the support plate 31 and is used to form the bottom wall of the annular groove 32a; the side baffle 322 is a circular ring structure, which is mounted on the trustee 321, specifically located at the outer edge of the outer peripheral surface of the trustee 321, and is used to form the side wall of the annular groove 32a; when combined, the trustees 321 in the two limit members 32 are in relative contact, thereby completing the splicing.

[0053] Through the above design, the regularity of the structure is improved, and under the premise of ensuring the stability of the structure, the amount of production materials is saved and the manufacturing cost is reduced.

[0054] Based on the above embodiments, Figure 5 As shown, for ease of assembly, the inner circumference of the tube holder 321 is provided with a plurality of limit blocks 323 spaced around the outer ring sleeve 1 , and the limit blocks 323 abut against the inner side of the support plate 31 .

[0055] After the assembly, the two support plates 31 use the limiting blocks 323 to axially limit the two combined limiting members 32 so that they are fixed at appropriate positions.

[0056] By providing the limit block 323, assembly is facilitated, manufacturing efficiency is improved, and the impact resistance of the rope pulley side is enhanced, further improving the structural strength and stability.

[0057] In some embodiments, Figure 5 As shown, in order to facilitate the installation of the support member 4 , the support member 4 is designed to be a hollow tubular structure with annular grooves 41 formed at both ends, and a through hole 311 matching the annular grooves 41 is formed on the support plate 31 .

[0058] Exemplarily, the support member 4 is a hollow circular tube structure, the annular groove 41 is a circular ring structure and is arranged concentrically with the support member 4, and the through hole 311 is a corresponding circular hole type.

[0059] When assembled, the two ends of the support member 4 are respectively plugged into the corresponding through holes 311 on the two support plates 31 through the annular clamping grooves 41, so as to be clamped and locked.

[0060] Through the above design, the support member 4 can be plugged into the two support plates 31, thereby improving the stability of the connection, facilitating the combined installation, and improving the production efficiency.

[0061] It should be noted that when processing the support disk 31 , the plurality of through holes 311 are used as positioning base points, so that the center hole and the outer peripheral surface of the support disk 31 can be accurately processed at the same time, which is convenient for production and manufacturing.

[0062] In some embodiments, Figure 1 and Figure 2 As shown, in order to improve the structural strength of the support plate 31, the support plate 31 is provided with a plurality of reinforcing ribs 312 arranged at intervals around the outer ring tube sleeve 1, and the reinforcing ribs 312 and the through holes 311 are arranged alternately at intervals. The reinforcing ribs 312 are preferably in a long strip structure, but can also be in other shapes, which is not specifically limited.

[0063] The reinforcement ribs 312 can compensate for the reduction in structural strength caused by the through holes 311 , thereby ensuring the stability of the overall structure and improving durability.

[0064] In some embodiments, Figure 4As shown, in order to improve the stability of the connection between the limiting member 32 and the supporting plate 31 , a limiting convex ring 313 extending outward along the axis is provided on the outer periphery of the supporting plate 31 , and the limiting convex ring 313 fits with the inner periphery of the limiting member 32 .

[0065] By providing the limiting convex ring 313 and making it fit with the inner circumference of the limiting member 32, the contact area between the two is expanded, the function of flipping and limiting is achieved, and the connection stability is improved.
