Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present invention, and should not be construed as limiting the present invention.

The first embodiment is as follows:

referring to fig. 4 to 7, a connecting structure of a tension cap includes: the end cap comprises a stretching end cap 1, wherein the stretching end cap 1 comprises a peripheral wall 11 and a bottom wall 12 connected with the peripheral wall, and a convex part 13 which protrudes in a direction away from the peripheral wall 11 is formed on the bottom wall 12; the protruding part 13 is used for sleeving the fixing ring 2, and a limiting edge is arranged at the position, close to the peripheral wall 11, of the protruding part 13, so that the fixing ring 2 is prevented from falling off to the bottom wall 12, and the fixing ring 2 is prevented from being rubbed with the bottom wall 12 and damaged; the fixing ring 2 comprises an outer ring body 21 and a limiting part 22 arranged at the bottom end of the outer ring body, and the height of the limiting part 22 is slightly higher than the thickness of the shockproof pad 3, so that the fixing ring 2 cannot be extruded to the stretching end cover 1; the top of the outer ring body 21 is provided with a stop block inwards, the stop block is arranged around the inner ring for a circle, and the inner side of the stop block just contacts the top end of the convex part 13 to play a role in limiting; the shockproof pad 3 is sleeved on the fixed ring 2; the protection cover 4 comprises a matching cavity 41 matched with the inner side of the fixing ring 2 in a matching mode and a circle of extension parts 42 arranged on the outer side of the matching cavity 41, the matching cavity 41 is clamped on the inner side of the protruding part 13, clamping is convenient, the extension parts 42 on the outer side of the protection cover are arranged around the matching cavity 41 in a circle, and the extension parts 42 are used for preventing the shockproof pad 3 from falling off in the opposite direction of stretching the end cover 1. Adopt such a mode, on the one hand can reduce the processing cost, that is to say need not set up again on retainer plate 2 and place the recess, machining processes has been reduced, on the other hand, to riveted mode, its installation is simpler, and riveted mode is difficult for taking out the antivrbration pad, can't carry out timely change etc., furthermore, to the connected mode of jump ring, if set up the jump ring, then need cooperate the jump ring, need set up all structures that can fix the jump ring such as recess or block arch for the jump ring on the retainer plate again, and finally, for the connected mode of spacing buckle, when the antivrbration pad received lateral pressure again, only the spacing buckle of a plurality of dispersion blockked, the pressure that receives is great, and this application is through self technical means, the lateral contact area has been increased, when making it pressurized, the possibility of deformation reduces.

Specifically, the matching cavity 41 includes a second peripheral wall 43, a contact plate 431 is disposed at the bottom of the second peripheral wall 43, and a circular through hole concentric with the contact plate 431 is formed in the contact plate 431, so as to allow the output shaft of the motor to extend out of the circular through hole, so that the output shaft of the motor can perform plane limit on the preventing cover 4.

The diameter of the second peripheral wall 43 near the contact plate 431 is smaller than that of the second peripheral wall 43 near the extension 42, so that the second peripheral wall is formed into a shape with a larger top and a smaller bottom, thereby preventing the cover 4 from interference fit when being inserted into the protrusion 13 of the tension end cover 1, and ensuring stable and firm connection and difficult looseness.

In some optional embodiments of the present invention, the second peripheral wall 43 contacts the extension portion 42 to form a rounded chamfer, so that no sharp corner injury to the operator occurs during manual operation.

In some alternative embodiments of the present invention, the extension 42 is higher than the crash pad 3, for example: when the extension portion 42 is lower than the crash pad 3, once the crash pad 3 is moved from the outside to the inside, a part of the side surface of the crash pad 3 is blocked by the extension portion 42, and a part of the side surface is not blocked, when the crash pad 3 is stressed, two different pressure differences occur on the side surface of the crash pad 3, so that the crash pad 3 is easily deformed, the normal operation is affected, the original effect is lost, and the replacement must be performed again; however, when the extension portion 42 is equal to or slightly higher than the crash pad 3, the above does not occur.

In some alternative embodiments of the present invention, the outside of the second peripheral wall 43 is provided with a convex pattern, which can improve the friction coefficient between the cover 4 and the inside of the protrusion 13 of the end cap 1, making the connection more stable.

Example two: on the basis of the first embodiment, the ribs arranged on the outer side of the second peripheral wall 43 are replaced by the concave ribs, so that the material is saved, and the friction coefficient is improved.

According to the utility model discloses a motor of second aspect embodiment, including the aforesaid connection structure of tensile end cover, this motor is still including setting up the installing support in the motor rear end, the fixed belt pulley of this installing support, this belt pulley passes through the belt with motor shaft end belt pulley and is connected, the motor protecgulum is fixed with the operation electric capacity in addition.

According to the third aspect of the present invention, the clothes dryer comprises the above-mentioned motor.

The working principle is as follows: the fixing ring is sleeved on the protruding portion of the stretching end cover, the shockproof pad is arranged on the outer ring of the fixing ring, and finally the cover is prevented from being clamped in the inner ring of the protruding portion through the motor shaft, one side of the shockproof pad is blocked by the limiting portion on the fixing ring, and the other side of the shockproof pad is blocked by the extending portion of the protection cover, so that the shockproof pad is not easy to fall off and cannot deform due to extrusion. In-process, it is extremely convenient to install, does not need the manual work to carry out too much calibration work yet, only need full manual operation can.

The foregoing is merely a preferred embodiment of the invention and is not intended to limit the invention in any way. The technical solutions of the present invention can be used by anyone skilled in the art to make many possible variations and modifications to the technical solution of the present invention, or to modify equivalent embodiments with equivalent variations, without departing from the scope of the technical solution of the present invention. Therefore, any modification, equivalent change and modification of the above embodiments according to the present invention are all within the protection scope of the present invention.
