Furthermore, a containing cavity is arranged in the supporting framework, and a connecting nut is arranged on the containing cavity.
Furthermore, the outer wall of the outer sleeve shell is provided with a connecting hole at a position corresponding to the containing cavity.
Furthermore, the cross section of the connecting hole is of a step-shaped structure.
Furthermore, a convex gasket used for preventing the sliding wheel from rotating and wearing the outer casing is arranged on the outer casing.
Furthermore, the end face structure of the supporting framework is a cross-shaped structure.
Furthermore, the supporting framework is made of metal sheets through stamping.
Furthermore, the outer casing is made of plastic through injection molding.
Compared with the prior art, the utility model has the advantages of it is following:
(1) when the pulley block is used, the diameter of the stamping hole in the supporting framework is larger than that of the pin joint rotating shaft, so that in use, the pin joint rotating shaft can move in the stamping hole in a small range, the sliding wheels are prevented from being separated from the rail, the four sliding wheels of the pulley block can be landed simultaneously, and the smoothness and the service life of the pulley are greatly improved.
(2) During the use, when the connecting hole of echelonment structure was assembling clamping screw, clamping screw can prop up the pore wall of connecting hole slightly to make clamping screw on the connecting hole fixed firm, and then avoided leading to the problem that the screw rod can fall back certainly because of push-and-pull back and forth movement, this assembly pulley still has convenient operation, easy advantage of implementing.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer and clearer, the present invention will be further described with reference to the accompanying drawings and examples.
As shown in fig. 1 to 6, this embodiment discloses a pulley block with stable stress for sliding door, including supporting framework 1 and outer shell 2, be equipped with outer shell 2 on supporting framework 1, outer shell 2 suit is at the outer wall of supporting framework 1, it is equipped with punching press hole 3 to be symmetrical on the outer wall of supporting framework 1, the position department that the outer wall of outer shell 2 corresponds punching press hole 3 is equipped with through-shaft hole 4, be equipped with pin joint pivot 5 on punching press hole 3, and the shaft diameter of pin joint pivot 5 is less than the aperture of punching press hole 3, pin joint pivot 5 passes through-shaft hole 4 and punching press hole 3 in proper order, and the double-phase opposite side end of pin joint pivot 5 all is equipped with movable pulley 6, movable pulley 6 can rotate on supporting framework 1 through pin joint pivot 5.
The outer casing 2 is also provided with a convex gasket 10 for preventing the sliding wheel 6 from rotating and wearing the outer casing 2; the end surface structure of the supporting framework 1 is a cross structure; the outer race 2 is provided with a raised washer 10 to prevent the sliding wheel 6 from wearing the outer race 2 during rotation.
The supporting framework 1 is made of metal sheets through stamping; the utility model discloses in consider supporting framework 1's supporting capacity, and life, the example of adoption is made for the sheetmetal punching press, can change supporting framework 1's material according to the demand in the in-service use.
The outer casing 2 is made of plastic by injection molding; the utility model discloses in consider outer jacket shell 2 make the cost, the example of adoption is that plastics are moulded plastics and are made, can change outer jacket shell 2's material according to the demand in the in-service use.
The utility model discloses a working process and principle are: firstly, placing a connecting nut 8 into a containing cavity 7 on a support framework 1, and sleeving an outer casing 2 on the outer wall of the support framework 1; then, a pin joint rotating shaft 5 sequentially penetrates through a through shaft hole 4 arranged on the outer casing 2 and a stamping hole 3 arranged on the support framework 1, and after two ends of the pin joint rotating shaft extend out of the outer casing 2, sliding wheels 6 are arranged at two ends of the pin joint rotating shaft 5, so that assembly of the pulley block is completed; then when the pulley block is assembled, the fixing bolt is inserted into the accommodating cavity 7 through the connecting hole 9 on the outer casing 2, the fixing bolt is assembled with the connecting nut 8 in the accommodating cavity 7 and then extends out of the supporting framework 1 to be connected with the sliding door, and when the fixing screw is assembled in the connecting hole 9 with the stepped structure, the hole wall of the connecting hole 9 can be slightly supported by the fixing screw, and the fixing screw can be clamped by the stepped structure of the connecting hole 9, so that the fixing screw on the connecting hole 9 is firmly fixed; finally, in practical use, the diameter of the stamping hole 3 on the support framework 1 is larger than that of the pin joint rotating shaft 5, so that in use, the pin joint rotating shaft 5 can swing in a small floating space in the stamping hole 3, and further, four sliding wheels are simultaneously stressed on a horizontal plane, so that the movement of the pulley block is smoother, the outer sleeve shell 2 can be prevented from being worn by the sliding wheels 6 when the sliding wheels 6 rotate through the convex gaskets 10 on the outer sleeve shell 2, and the pulley block also has the advantages of convenience in operation and easiness in implementation.
