In order to make the technical solutions of the present invention better understood by those skilled in the art, the technical solutions of the present invention are further described below by way of specific embodiments with reference to the accompanying drawings.
Example one
This embodiment provides a washing machine lock, and this lock can shelter from the emergent stay cord among the prior art, prevents that children from discovering emergent stay cord and leading to the unable normal work of washing machine in the work because of the emergent stay cord of curiosity pulling. The door lock comprises a door lock body 1, a rotating wheel 2 and a pulling mechanism connected with the door lock body 1, wherein the pulling mechanism is also connected with the rotating wheel 2. The pulling mechanism is used for pulling down the door lock body 1 or releasing the door lock body 1 along with the rotation of the rotating wheel 2.
As shown in fig. 1-2, the pulling mechanism is an emergency pulling rope 4, one end of the emergency pulling rope 4 is connected to the door lock body 1, and the other end of the emergency pulling rope 4 pulls the door lock body 1 along with the rotation of the turning wheel 2, i.e. the other end of the emergency pulling rope 4 is wound on the turning wheel 2 and is continuously wound on the turning wheel 2 or gradually separated from the turning wheel 2 along with the rotation of the turning wheel 2, and because the length of the emergency pulling rope 4 is reduced, the emergency pulling rope 4 can pull the door lock body 1 during winding on the turning wheel 2, wherein the turning wheel 2 is arranged in a thread scrap filter box 10 of the washing machine. The rotating wheel 2 is provided with a screwing part 3 on the side wall extending out of the thread scrap filter box 10. I.e. the side wall of the rotating wheel 2 that is visible to the user, is provided with a screw 3, which screw 3 is coplanar with the side wall of the lint filter cartridge 10. This kind of structure can guarantee that children open the back of thread scraps filter box 10, because of can't see emergent stay cord and can not stimulate emergent stay cord 4 at will in this thread scraps filter box 10 and open the washing machine door.
As shown in fig. 1, the screwing portion 3 is a screwing groove, wherein the screwing groove is shaped as a cross-shaped groove, when the rotating wheel 2 needs to be rotated, a household cross screwdriver needs to extend into the cross-shaped groove to screw the screwdriver so as to drive the rotating wheel 2 to rotate, so that the rotating wheel 2 winds the emergency stay cord 4 thereon, the length of the emergency stay cord 4 is shortened, and the purpose of pulling down the door lock body 1 is achieved.
As shown in fig. 3, the rotating wheel 2 includes a working portion 21 and rotating portions 22, wherein the working portion 21 is in contact with the pulling mechanism, and the rotating portions 22 are provided at both ends of the working portion 21, and each rotating portion 22 extends into the lint filter cartridge 10 and is disposed coplanar with the outer side surface of the sidewall thereof. The screwing part 3 is arranged on a rotating part 22, and the screwing part 3 is exposed out of the outer wall of the thread scrap filter groove, so that the thread scrap filter groove is convenient for a user to find. The working part 21 is further provided with a winding groove 211, the winding groove 211 can wind the emergency pull rope 4 in the winding groove 211, and the emergency pull rope 4 is prevented from being separated from the pulling wheel 2 to prevent the emergency function of the door lock from being abnormal.
As shown in fig. 4, the screwing groove is a regular hexagon groove, and a hexagonal screwdriver needs to be inserted into the screwing groove to drive the rotating wheel 2 to rotate, so as to realize the pull-down task of the emergency pull rope 4.
As shown in fig. 5, the screwing part 3 is a screwing protrusion, the shape of the screwing protrusion is a regular hexagon structure, and an internal hexagonal screwdriver is required to drive the rotating wheel 2 to rotate, so that the rotating wheel 2 winds the emergency pull rope 4 around the rotating wheel 2, the length of the emergency pull rope 4 is shortened, and the purpose of pulling the door lock body 1 downwards is achieved.
Because rotate the wheel 2 and set up in this embodiment at thread scrap filter box 10 to fix on the lateral wall of thread scrap filter box 10, consequently, when the protecgulum of this thread scrap filter box 10 is opened to the child, owing to do not rotate the instrument of rotating wheel 2, consequently, can effectually prevent children from pulling emergent stay cord 4, emergent stay cord 4 winding is on rotating wheel 2, can also effectually avoid the user to pull more long more at the emergent stay cord 4 of pulling in-process, prevent that the pulling is hard, the inconvenient problem of operation takes place.
The embodiment also provides a washing machine which comprises a washing machine door body and a machine shell, wherein the washing machine door body is arranged on the machine shell, and the washing machine door lock provided by the embodiment is also included. The pulling mechanism of the washing machine emergency door lock is hidden, so that the situation that children pull the pulling mechanism to open the door lock to influence the work of the washing machine can be prevented.
Example two
This embodiment provides a washing machine lock, and this lock can shelter from the emergent stay cord among the prior art, prevents that children from discovering emergent stay cord and leading to the unable normal work of washing machine in the work because of the emergent stay cord of curiosity pulling. The door lock comprises a door lock body 1, a rotating wheel 2 and a pulling mechanism connected with the door lock body 1, wherein the pulling mechanism is also connected with the rotating wheel 2. The pulling mechanism is used for pulling down the door lock body 1 or releasing the door lock body 1 along with the rotation of the rotating wheel 2.
As shown in fig. 6 and 7, the rotating wheel 2 is a gear, correspondingly, the pulling mechanism is a rack 5, the gear is arranged in the thread scrap filter box 10, one end of a rotating shaft of the gear extends out of the thread scrap filter box 10, and one end of the rack 5 extends into the thread scrap filter box 10 and is meshed with the gear. It should be noted that the end of the rack 5 connected to the door lock body 1 is not provided with teeth.
When the rotary wheel 2 is rotated, the rack 5 engaged with the rotary wheel 2 is moved up and down according to the rotation of the rotary wheel 2. One end of the rack needs to extend into the thread scraps filter box 10 to be meshed with the rotating wheel 2; meanwhile, the rotating wheel 2 is meshed with the rack, so that the rotating wheel 2 and the rack can be restricted with each other, and the rotating wheel 2 is prevented from being loosened in the rotating process.
It should be noted that the structure of the screwing part 3 in this embodiment is the same as that in the first embodiment, and is not described in detail in this embodiment.
In the washing machine door lock provided in the embodiment, the pulling mechanism is a rack, the rotating wheel 2 is a gear, wherein the rack is engaged with the gear, so that the door lock body connected with the rack can be pulled along with the downward movement of the rack, and the screwing part 3 is a screwing protrusion or a screwing groove, so that the screwing part 3 cannot be easily rotated by children, and the normal operation of the washing machine is ensured.
