DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] See also Figure 1 , Figure 2 The utility model provides an embodiment: a car pulley with an anti-slip and limiting function, comprising: a pulley body 1, wheel discs 2 are arranged at both ends of the pulley body 1, a plurality of spaced limiting cams 3 are arranged between the wheel discs 2, a bearing 5 is arranged at the middle position of the wheel disc 2, and an axial hole 6 is opened at the middle position of the bearing 5; belt grooves 4 are formed between the wheel discs 2 and the plurality of limiting cams 3 at both ends, the wheel discs 2 and the limiting cams 3 are both larger than the belt groove 4, so that the belt is embedded in the groove and is limited by the wheel discs 2 and the limiting cams 3, and is not easy to slip off.

[0022] See also Figure 1 , Figure 2 , Figure 4 , an anti-slip limit assembly 7 is arranged at the periphery of the rear end of the pulley body 1, and the anti-slip limit assembly 7 includes a first anti-slip limit piece 8 and a second anti-slip limit piece 9, and the first anti-slip limit piece 8 is located above the second anti-slip limit piece 9, and the inner walls of the first anti-slip limit piece 8 and the second anti-slip limit piece 9 are both provided with anti-slip limit blocks 11 for limiting the belt from slipping off, and further, the first anti-slip limit piece 8, the second anti-slip limit piece 9 and the anti-slip limit block 11 are all arc-shaped structures; the first anti-slip limit piece 8 and the second anti-slip limit piece 9 are plug-in The belt is assembled in a snap-fitting manner. When assembling, the insertion rod 14 of the first anti-slip limit piece 8 is aligned with the slot 15 of the second anti-slip limit piece 9, and the first anti-slip limit piece 8 is pressed down to insert the insertion rod 14 into the slot 15 for snapping. The first anti-slip limit piece 8 and the second anti-slip limit piece 9 form a semicircular arc structure. After the assembly, the anti-slip limit block 11 will be inserted into the belt groove 4 at the corresponding position. The belt is limited by the anti-slip limit piece and the anti-slip limit block 11, so that the belt is difficult to detach from the pulley, thereby achieving the effect of limiting and preventing detachment.

[0023] See also Figure 2The end of the first anti-slip limiter 8 is integrally provided with an assembly block 12, and a positioning bolt 13 is installed in the groove of the outer wall of the assembly block 12; the first anti-slip limiter 8 is fixed to the position of the car near the rear end of the pulley by the assembly block 12 and the positioning bolt 13, and is used to limit the pulley;

[0024] During disassembly, it is only necessary to first remove the positioning bolt 13 at the assembly block 12, and then remove and separate the first anti-slip limiter 8 and the second anti-slip limiter 9, so that the user can quickly disassemble, assemble and replace them.

[0025] See also Figure 2 The inner walls of the first anti-slip limit piece 8 and the second anti-slip limit piece 9 are both provided with an arc-shaped slot 10 that matches the shape of the anti-slip limit block 11. Furthermore, the arc-shaped slot 10 is combined with the anti-slip limit block 11 by using any one of mortise and tenon joints and bonding; the mortise and tenon joint structure is used for fixing, so that the slot 10 and the anti-slip limit block 11 are detachable, which is convenient for users to disassemble and remove the anti-slip limit block 11 for replacement; the bonding structure is used for fixing, so that the anti-slip limit block 11 can be bonded in the groove, which can improve the firmness of the anti-slip limit block 11 and the slot 10.

[0026] See also Figure 4 A rubber strip 16 is bonded to the contact surface between the anti-slip limit block 11 and the belt; the provision of the rubber strip 16 can prevent the belt from directly contacting the anti-slip limit block 11, thereby avoiding wear between the anti-slip limit block 11 and the belt, and the rubber strip 16 has a telescopic structure, which can provide the belt with a certain transmission retraction space; further, the rubber strip 16 is bonded to the anti-slip limit block 11 by bonding, and the rubber strip 16 can be replaced separately later by tearing off the rubber strip 16 without disassembling the anti-slip limit block 11, which is convenient for users.

[0027] Working principle: When in use, the belt is pre-set in the belt groove 4. After the belt is set, the insertion rod 14 of the first anti-slip limiter 8 is aligned with the slot 15 of the second anti-slip limiter 9, and the first anti-slip limiter 8 is pressed down to insert the insertion rod 14 into the slot 15 for engagement. The first anti-slip limiter 8 and the second anti-slip limiter 9 form a semicircular arc structure, and then are fixed to the rear end of the pulley by the positioning bolt 13 at the assembly block 12. When the pulley is operating, the anti-slip limiter 11 will be inserted into the belt groove 4 at the corresponding position, and the belt is limited by the anti-slip limiter and the anti-slip limiter 11, so that the belt is difficult to detach from the pulley, thereby achieving the effect of limiting and preventing detachment.

[0028] During disassembly, it is only necessary to first remove the positioning bolt 13 at the assembly block 12, and then remove and separate the first anti-slip limiter 8 and the second anti-slip limiter 9, so that the user can quickly disassemble, assemble and replace them.

[0029] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
