[0002] In recent years, with the improvement of living standards, household appliances have also developed rapidly. As we all know, washing machines are an indispensable part of household appliances, which can perform laundry operations quickly and efficiently. Double-barrel washing machines are washing and dehydrating machines that are composed of a washing barrel and a dehydrating barrel. Its advantages are that washing and dehydrating can be performed separately. This type of washing machine has high cleaning efficiency, low power consumption, and the washing and dehydrating time can be selected at will.

[0003] The conventional washing machine cover is generally directly connected to the housing for rotation and is used to close or open the washing port or the dehydration port. However, when such a washing machine cover is in use, it lacks damping force when it is closed, so it is easy to collide, causing the cover or the housing to directly collide, causing irreversible damage and affecting the opening and closing effect of the cover. In order to solve this technical problem, the prior art provides some dampers at the positions of the cover and the housing shaft for buffering, which can achieve a buffering effect. However, the applicant found in actual use that when the damper is used for a long time, due to the internal rotational friction, the internal damping grease is gradually reduced, which will eventually cause the damping effect of the damper to be greatly reduced, affecting the damping effect, and eventually losing the damping effect, affecting the opening and closing effect of the washing machine housing.

[0038] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0039] Please refer to 1-10, a washing machine cover damper, including a damping shell 11, which is detachably mounted on a base 2, a connecting column 12 is further provided at one end of the damping shell 11, the connecting column 12 is used to be connected to the cover 1, a baffle plate 121 is provided at one end of the connecting column 12, the baffle plate 121 is rotatably arranged in the damping shell 11, and a rotation space is formed between the baffle plate 121 and the damping shell 11;

[0040] The damping shell 11 is also provided with an adjusting member.

[0041] A sealing block 122 is provided at one end of the baffle plate 121. A plurality of through holes 1221 are opened on the sealing block 122. A storage space 1101 is formed between the sealing block 122 and the adjusting member. The storage space 1101 is used to store damping grease. The adjusting member is used to squeeze the storage space 1101 so that the damping grease in the storage space 1101 enters the rotating space through the through hole 1221.

[0042] Specifically, the rotation space refers to Fig.10 As shown, the space between the baffle plate 121 and the damping shell 11 has a certain amount of damping grease in the control, so that when rotating, the rotation speed of the baffle plate 121 and the inner wall of the damping shell 11 can be slowed down, and a damping effect is achieved. The storage space 1101 refers to Fig. 9 The position of 1101 shown is located between the sealing block 122 and the sealing plate 4 , and the storage space 1101 is connected with the rotating space through the through hole 1221 .

[0043] The present invention provides a sealing block 122 and an adjusting member, so that when the damping effect deteriorates during long-term use, the adjusting member in the damping shell 11 can be driven to slide along the damping shell 11, and can be used to squeeze the damping grease in the storage space 1101, so that the damping grease in the storage space 1101 flows into the rotating space, and more damping grease enters the rotating space, thereby increasing the damping force between the baffle plate 121 and the inner wall of the damping shell 11 and improving the damping effect. Therefore, there is no need to replace the damper to achieve a better damping effect, which greatly improves the safety performance between the washing machine and the cover plate 1 and reduces the collision between the two.

[0044] In an embodiment further provided by the present invention, the baffle plate 121 forms a wavy structure with the side edge, and a certain gap is formed between the inner walls of the damping shell 11, and the damping grease flows through the gap during rotation, thereby forming a damping force.

[0045] In an embodiment further provided by the present invention, the adjusting member includes a sealing plate 4 disposed in the damping shell 11, and one end of the sealing plate 4 protrudes to the damping shell 11, and the sealing plate 4 is threadedly connected to the damping shell 11. Specifically, the present application can rotate the sealing plate 4 so that the sealing plate 4 can be axially adjusted.

[0046] In an embodiment further provided by the present invention, a fixing block 21 is further provided on the seat body 2. A tightening assembly is also provided on the fixing block 21. The tightening assembly acts on the sealing block 122 and is used to drive the adjusting member to adjust.

[0047] In the embodiment further provided by the present invention, the abutting assembly includes a connecting rod 211 rotatably arranged on the fixed block 21, and a third elastic member 2112 is sleeved on the connecting rod 211. Under the elastic force of the third elastic member 2112, the connecting rod 211 has a tendency to move toward the direction of the adjusting member, and the abutting assembly is locked by the locking assembly. After the locking assembly is unlocked, the abutting assembly is unlocked and abuts against the sealing plate 4 under the elastic force of the third elastic member 2112. The connecting rod 211 provided by the present invention also has another effect, that is, when in use, the damping force can be pre-adjusted by the abutting assembly through the user's experience. For example, in the process of just using, if the damping force is small, the abutting assembly can be directly driven to rotate, compressing the storage space 1101, so that the damping grease in the storage space 1101 flows into the rotating space 1201 to adapt to the appropriate damping force. If the damping force is large, the abutting assembly can be adjusted in the opposite direction, that is, the use effect and functionality of the device can be further improved.

[0048] Furthermore, the locking assembly includes a locking rod 311 slidably disposed on the fixed block 21 , and a second elastic member 3111 is disposed at one end of the locking rod 311 . Under the elastic force of the second elastic member 3111 , the locking rod 311 can be inserted into the groove of the connecting rod 211 .

[0049] Furthermore, the seat body 2 is also provided with a limiting mechanism for locking the damping shell 11, and the limiting mechanism includes a locking block 3 slidably arranged on the seat body 2, and a spring is sleeved on one end of the locking block 3, under which the locking block 3 can be inserted into the locking groove in the damping shell 11. The present invention can achieve passive unlocking of the connecting rod 211 by squeezing the locking block 3 when the damper is installed, so that the connecting rod 211 can be abutted against the sealing plate 4, which can not only improve the coaxiality of the sealing plate 4, but also adjust the position of the sealing plate 4 by rotating the connection during subsequent use, so that the damping grease in the storage space 1101 enters the grease rotation space 1201 to compensate for the damping grease, greatly improving the installation efficiency, and ensuring the damping effect of the connecting column 12 under long-term use.

[0050] Furthermore, the limiting mechanism can drive the locking rod 311 to disengage from the connecting rod 211 through a guide portion, and the guide portion is arranged in the locking block 3. When the damping shell 11 is inserted into the seat body 2, the guide portion is triggered to move to drive the locking rod 311 to disengage from the connecting rod 211.

[0051] Furthermore, the guide portion includes a limiting groove 301 and a horizontal slide groove 304 provided in the locking block 3, the limiting groove 301 is connected with the horizontal slide groove 304, the limiting groove 301 has a first position 302 and a second position 303 respectively, and a guide column 31 is further provided at the lower end of the locking rod 311, and both ends of the guide column 31 are respectively located in the limiting groove 301, and when the locking block 3 slides inwardly, it can be limited by the limiting groove 301, so that the locking block 3 slides to the first position 302, and the locking rod 311 tends to move in a direction away from the connecting rod 211;

[0052] An elastic stopper 32 is rotatably disposed in the limiting groove 301, and a torque spring is disposed on the rotating shaft of the elastic stopper 32, whose elastic force can make one end of the elastic stopper 32 abut against the inner wall of the limiting groove 301 near the third position 305. Specifically, under the elastic force of the torque spring, the specific structure and position of the elastic stopper 32 are as follows: Figure 3 The position shown in the figure, and then when the guide column 31 slides, it can squeeze the elastic block 32 to rotate along its axis, so that one end of the elastic block 32 can be against the position of point a, and then the guide column 31 can smoothly slide to the first position 302.

[0053] Specifically, a friction block 212 is also slidably provided on the connecting rod 211, and a first elastic member 2121 is provided between the friction block 212 and the connecting rod 211, and one end of the friction block 212 is connected to a pull rope 213, and the other end of the pull rope 213 is connected to the pull rod 2113, and the pull rod 2113 can slide axially along the connecting rod 211, and the pull rope 213 is supported and guided by the guide wheel, and a coaxial rod 123 is provided at one end of the connecting column 12, and the coaxial rod 123, the coaxial rod 123 One end of the connecting rod 123 passes through the sealing plate 4, that is, through the above structure, during installation, the coaxial rod 123 can be inserted into the connecting rod 211, and the side wall is in contact with the friction block 212. The coaxial rod 123 is provided with barbs that match the friction block 212, that is, when the friction block 212 is connected to the barbs, the movement of the coaxial rod 123 can be limited, that is, the movement of the entire connecting column 12 can be limited, and the stability of the connecting column 12 of the device during rotation can be improved. Prevent the occurrence of oil leakage in the axial direction, and further improve the damping effect.

[0054] When installing the present invention, first, in the initial position, the locking rod 311 is inserted into the locking groove on the connecting rod 211, and the locking block 3 protrudes into the frame, and the damping shell 11 has damping grease, that is, the rotating space 1201 and the storage space 1101 both have damping grease, and at this time, the lower end of the damping shell 11 is installed in the seat body 2, and during the insertion process, the lower end of the damping shell 11 squeezes the locking block 3, so that the locking block 3 is pressed into the seat body 2, that is, the guide part is driven to move, and then during the movement, due to the guide column 31 at the lower end of the locking rod 311, the limiting groove 301, and then during the movement, the locking rod 311 gradually moves away from the connecting rod 211 under the limit of the limit groove 301, and then completely separates from the connecting rod 211, and at this time the guide column 31 is in the first position 302 of the limit groove 301, and then after the damping shell 11 is installed in place, the locking groove opened on its side wall corresponds to the locking block 3, and then the locking block 3 is inserted into the locking groove under the elastic force of the spring sleeved on the outside, that is, the damping shell 11 can be quickly locked, and at this time the guide column 31 is in the third position 305 of the limit groove 301;

[0055] At this time, the connecting rod 211 is also unlocked, and then under the elastic force of the third elastic member 2112, the end of the connecting rod 211 can be inserted into the damping shell 11, and then the synchronization block 2111 set at the end of the connecting rod 211 is inserted into the groove opened on the sealing plate 4. Note that at this time, even if the synchronization block 2111 is not accurately inserted, the connecting rod 211 can be rotated to perform alignment and insertion, and at this time, the friction block 212 contacts the barbs set on the outside of the coaxial rod 123, that is, it can be used to limit the movement of the coaxial block, that is, through the above installation steps, the damper can be quickly installed;

[0056] When it is necessary to add damping grease later, it is only necessary to pull the pull rope 213 outward, and then the pull rope 213 drives the connected friction block 212 to make the friction block 212 disengage from the barb of the coaxial rod 123, and then continue to pull. When it is pulled to a certain position, it can drive the connecting rod 211 to move outward synchronously, and then make the locking groove on the connecting rod 211 correspond to the locking rod 311, and the locking rod 311 is inserted into the locking groove under the elastic force of the second elastic member 3111, and the elastic force of the second elastic member 3111 is set to be greater than the elastic force of the spring sleeved on the locking block 3, and the locking rod 3 When 11 is inserted into the locking slot, since the lower guide column 31 is in the third position 305 of the limit slot 301, that is, when the locking rod 311 moves upward, it can pass through the limit of the limit slot 301, so that the guide column 31 moves from the third position 305 to the second position 303 through the elastic block 32, that is, during the movement, it will drive the locking block 3 to shrink inward, that is, it can unlock the restriction on the damping shell 11, and then the damping shell 11 can be disassembled for corresponding maintenance, that is, while achieving the desired locking, it can also be quickly unlocked, and the linkage and functionality are relatively high.
