The free end of the second sub-piece 152 is bent to form a buckle-like structure 1521 for fastening the free end of the first clamping piece 23. The snap-in hole 16 is used to snap-in the free end of the pull rod 12. The position of the rotary cage body 3 corresponding to the guide 25 is provided with a pin seat 31 for inserting the pin 14 therein to lock the rotary cage door 2. The position of the rotary cage door 2 corresponding to the locking mechanism 1 is provided with a hollow part 26, and one end of the rotary cage door 2 of the hollow part 26 extends to the other end. A limit baffle 27 is arranged in the middle of the hollow part 26, and the pull rod 12 abuts against the limit baffle 27 to open the rotary cage door 2.

The embodiment of the utility model provides a rotating cage door lock device of washing and dehydrating machine, its locking mechanism 1 can be used to drive rotating cage door 2 and open and block the opening of rotating cage body 3. The guide 25 guides the pin 14, and the pin 14 can move in the guide 25 by the connecting rod 13 and the pull rod 12. The bolt seat 31 and the guide 25 are correspondingly arranged, so that the bolt 14 can conveniently enter the bolt seat 31 to lock the rotating cage door 2 on the rotating cage body 3. When the rotary cage door 2 needs to be opened, the bolt 14 can be slowly separated from the bolt seat 31 only by pulling the pull rod 12 in the opposite direction, and when the pull rod 12 abuts against the limit baffle 27, the pull rod 12 is limited and cannot move continuously. At this time, the bolt 14 is just separated from the inside of the bolt seat 31, and the rotary cage door 2 can be opened. The process is convenient to operate, high in safety and free of misoperation, and injury to operators is avoided.

The rotating cage door 2 is hinged with the opening of the rotating cage body 3. When the washing and dehydrating machine washes linen, the opening of the rotating cage body 3 is blocked by the rotating cage door 2. When the linen washing is finished, the rotating cage door 2 is opened so as to take out the linen. In one embodiment, referring to fig. 3 to 7, the rotary door 2 may include a fixed frame 21 and a cover plate 22 mounted to the fixed frame 21. The contour of the cover plate 22 is matched with that of the rotating cage body 3, so that after the rotating cage door 2 is arranged on the rotating cage body 3, the rotating cage door is attractive, and the rotating cage door 2 is convenient to open and close relative to the rotating cage body 3.

The pull rod 12 is hinged to the fixed support 11, one end of the connecting rod 13 is hinged to the pull rod 12, and the other end of the connecting rod is hinged to a bolt 14. Specifically, the pull rod 12 may include a grip portion 121 and a connecting portion 122 connected to the grip portion 121 for hingedly connecting the fixing support 11. The connecting rod 13 is hinged to the connecting portion 122.

Further, the elastic locking piece 15 may include a first segment 151 fixed to the fixing support 11 and a second segment 152 fixedly connected to the first segment 151. The second section 152 has a fastening hole 16, and the second section 152 is sleeved on the latch 14 through the fastening hole 16. The first sub-piece 151 and the second sub-piece 152 may be integrally formed, and the first sub-piece 151 and the second sub-piece 152 may be made of a metal material having elasticity, such as steel. The first and

second segments

151 and 152 may be disposed at an angle ranging from 90 degrees to 120 degrees. The first sub-piece 151 is not in contact with the connecting member 211 except for the end portion thereof fixed to the connecting member 211 by the fixing bracket 11, and the second sub-piece 152 is not in contact with the first catching piece 23. In this way, it is ensured that the spring clip 15 is not obstructed during use.

Further, the catching hole 16 may include a latch connecting hole 161 and a lever connecting hole 162. The latch coupling hole 161 is located at a side of the lever coupling hole 162 facing the first segment 151. A limiting protrusion 1211 is disposed at a free end of the holding portion 121 of the pull rod 12, and the limiting protrusion 1211 is inserted into the pull rod connection hole 162. The opening of the pull rod connection hole 162 is gradually enlarged from the free end of the second sub-piece 152 to the plug pin connection hole 161, so that the limiting protrusion 1211 can be conveniently inserted into the pull rod connection hole 162 and taken out of the pull rod connection hole 162.

Referring to fig. 1, 5 and 6, a first retaining piece 23 and a second retaining piece 24 are provided at an end of the revolving cage door 2 facing the latch 14. Wherein, the first clamping piece 23 and the second clamping piece 24 can be arranged on the fixed frame 21. A guide 25 is inserted between the first and second catching

pieces

23 and 24, and the latch 14 is slidably coupled to the guide 25 through the latch coupling hole 161. The guiding element 25 may be a hollow tube structure, and the guiding element 25 is opposite to the pin connecting hole 161. Thus, the latch 14 can be moved in the guide 25 by pulling the pull rod 12. The position of the rotating cage body 3 corresponding to the guide piece 25 is provided with a bolt seat 31, and the free end of the bolt 14 passes through the guide piece 25 and can be inserted into the bolt seat 31 so as to lock the rotating cage door 2.

Referring to fig. 5 to 9, the free end of the second sub-piece 152 can be bent into a buckle-like structure 1521 for fastening the free end of the first clamping piece 23. Gaps are reserved on the two side walls and the top end of the buckle-shaped structure 1521 and the first clamping piece 23. Thus, when the limiting protrusion 1211 of the pull rod 12 is inserted into the pull rod connection hole 162, the pull rod 12 can be taken out of the pull rod connection hole 162 only by pulling the buckle-shaped structure 1521. Further, the first locking piece 23 is provided with a limiting member 4, the limiting member 4 extends into the pull rod connection hole 162 for cooperating with the limiting protrusion 1211, and the limiting member 4 is located on a side of the limiting protrusion 1211 facing the pin connection hole 161. Specifically, when the pull rod 12 is ready to be installed in the pull rod connection hole 162, the buckle-shaped structure 1521 is shifted toward the plug seat 31, then the pull rod 12 is pulled toward the pull rod connection hole 162, when the pull rod 12 abuts against the limiting member 4, the buckle-shaped structure 1521 is released, and at this time, the buckle-shaped structure 1521 rebounds, so that the limiting protrusion 1211 can be embedded in the pull rod connection hole 162.

Referring to fig. 1 to 7, a hollow portion 26 is disposed at a position of the rotary cage door 2 corresponding to the locking mechanism 1, and the hollow portion 26 extends from one end of the rotary cage door 2 to the other end thereof. A limit baffle 27 is arranged in the middle of the hollow part 26, and the pull rod 12 abuts against the limit baffle 27 to open the rotary cage door 2. Specifically, both sides of the limit stop 27 are recessed inward. Correspondingly, the connecting portion 122 of the pull rod 12 is provided with a curved arc surface adapted to the side edge of the limiting baffle 27, when the curved arc surface of the connecting portion 122 abuts against the side edge of the limiting baffle 27, the connecting portion 122 cannot move continuously due to the limitation of the side edge of the limiting baffle 27, and at this time, the plug 14 just breaks away from the inside of the plug seat 31, and the revolving door 2 can be opened.

Referring to fig. 5, the present invention includes an elastic support piece 5, one end of which is fixed to the fixing support 11, and the other end of which is connected to the connecting rod 13. Specifically, the elastic abutting piece 5 may be a bent metal strip, one end of which is fixed to the fixing support 11 by a screw, and the other end of which abuts against the connecting rod 13. Therefore, when the pull rod 12 drives the elastic resisting piece 5 to move, the elastic resisting piece 5 can provide the connecting rod 13 with a force opposite to that of the pull rod 12, and the stability of the connecting rod 13 in the moving process can be ensured.

Referring to fig. 1 and 5, a handle 6 may be mounted to the free end of the second catch 24, the handle 6 extending in a direction toward the first catch 23. When the rotating cage door 2 is unlocked, the rotating cage door 2 can be opened through the handle 6. Similarly, when the revolving cage door 2 needs to be closed, the revolving cage door 2 can be closed to the opening of the revolving cage body 3 through the handle 6.
