According to the application, the locking mechanism for locking the rotating block 32 is arranged on the first transmission shaft 2, namely, in the process of overload protection, the rotating block 32 can be locked through the locking mechanism, so that the rotating block 32 is not abutted against the third transmission shaft 4 any more, namely, the rotating block 32 is always in a locked state in the whole process of overload operation of the motor, at the moment, the first driving motor 11 can not have larger friction with the rotating block 32 even in idle operation, thereby not only further reducing the rotation load of the motor, but also greatly reducing the abrasion between the rotating blocks 32 and integrally prolonging the service life of the device.
In a further embodiment of the present application, when the rotating block 32 abuts against the pressing block 211, the pressing block 211 presses the first transmission rod 22, and the locking member is inserted into the locking groove 3201 through the transmission of the second transmission rod 23 to lock the rotating block 32, and in this embodiment, the present application further includes a supporting frame 111 disposed on the machine body, a thrust bearing 112 is disposed above the supporting frame 111, and the second transmission shaft 3 is fixedly disposed on the thrust bearing 112.
Further, in the application, as shown in fig. 5, a limiting block 311 is slidably disposed in the second transmission shaft 3, the limiting block 311 can be slidably disposed in a limiting chute 402 formed on the third transmission shaft 4, and a first elastic member 312 is sleeved on the limiting block 311 under the elasticity of the limiting block, so that the limiting block 311 can be inserted into an inner ring of the second transmission shaft 3, and a pull block 31 is disposed at one end of the limiting block 311, when the pulling block is pulled outwards during disassembly, the limiting block 311 can be driven to move towards the outside of the second transmission shaft 3, and when the first driving motor 11 idles, the rotational coaxiality of the third transmission shaft 4 can be improved through the arrangement of the limiting block 311, and the friction force between the third transmission shaft 4 and the inner wall of the second transmission can be reduced.
In the present application, the supporting elastic member 25 is provided, which not only can buffer the force of the rotating disc 1 in the vertical state during rotation, but also can bear the clothes on the rotating disc 1 and above, and the elastic force is set to be such that when the clothes in the drum are too much, the rotating force of the first rotating shaft and the second rotating shaft is larger than the rotating force of the first driving motor 11, the supporting elastic member 25 is compressed and deformed, and the whole sliding lock piece 21 moves downwards.
When clothes with more gravity appear, the gravity acts on the rotary disk 1, then the elastic piece 25 is supported to generate compression deformation, the whole sliding lock block 21 moves downwards, so that the sliding lock block 21 moves downwards to the notch of the sliding groove 302, the force applied to the second transmission shaft 3 is larger than a preset value, the first transmission shaft 2 and the second transmission are difficult to rotate due to the larger bearing force, namely the rotation power of the third transmission shaft 4 can lead the rotation block 32 to be separated from the transmission groove 401, the synchronous idling of the third transmission shaft 4 and the first driving motor 11 is realized, when the first driving motor 11 realizes the idling, the rotation block 32 is extruded into the second transmission shaft 3 at the moment, then the second transmission shaft 3 moves towards the direction of the sliding lock block 21 and is abutted on the extrusion block 211, the extrusion block 211 is extruded, then the extrusion block 211 slides into the sliding lock block 21, i.e. the first transmission rod 22 abutting against the pressing block 211 is pressed, and then the first transmission rod 22 drives the second transmission rod 23 movably connected with the first transmission rod 22 to rotate, i.e. the locking piece moves towards the direction of the rotating block 32, i.e. moves into the locking groove 3201 along the inclined plane of the second locking block 321, the rotating block 32 is locked, i.e. when the first driving motor 11 drives to rotate, the third transmission shaft 4 does not generate larger friction with the rotating block 32, so that the overload protection of the operation of the first driving motor 11 can be achieved, when the clothes are more and the rotation load of the motor is greater, the motor is idle to maximally protect the first driving motor 11, then when the clothes are gradually reduced, i.e. the upper part of the first transmission shaft 2 is subjected to lighter bearing force, the sliding locking piece 21 rises under the elasticity of the supporting elastic piece 25, that is, at this time, the vertical positions of the second locking block 321 and the first locking block 241 are staggered, that is, the second locking block 321 is not interfered by the first locking block 241, then the locking of the rotating block 32 is released, the rotating block 32 is inserted into the second transmission shaft 3 under the elasticity of the spring, and then is inserted into the transmission groove 401, and under the rotation of the first driving motor 11, the rotating block 32 is driven to rotate, so that the power transmission is realized, that is, when the bearing force is received above the first transmission shaft 2, that is, the bearing force is smaller than the preset value, the driving force of the first driving motor 11 realizes the rotation of the second transmission shaft 3 through the transmission of the third transmission shaft 4 and the rotating block 32, that is, the power transmission is realized.
While certain exemplary embodiments of the present application have been described above by way of illustration only, it will be apparent to those of ordinary skill in the art that modifications may be made to the described embodiments in various different ways without departing from the spirit and scope of the application. Accordingly, the drawings and description are to be regarded as illustrative in nature and not as restrictive of the scope of the application, which is defined by the appended claims.
