The specific meaning of the above terms in the present utility model will be understood in specific cases by those of ordinary skill in the art.

As shown in fig. 1 to 3, the present utility model provides a push-latch mechanism 100, which push-latch mechanism 100 can be used in a drum cover device to enable opening and closing of a cover 300 of the drum cover device with respect to a tub 200. It should be noted that the present embodiment is not limited to a specific type of the drum cover device, and the drum cover device may be a shoe washer, a trash can, a food storage box, or the like, so long as the drum cover device has a drum body 200 for accommodating articles and a cover body 300 for opening and closing an opening of the drum body 200. And, one end of the tub 200 and one end of the cover 300 of the tub cover are rotatably connected by a rotation shaft, and the push-and-eject mechanism 100 is disposed between the other end of the tub 200 and the other end of the cover 300 of the tub cover, that is, the rotation shaft is disposed opposite to the push-and-eject mechanism 100 on the tub cover.

Specifically, the ejector mechanism 100 includes a snap assembly and a snap groove 130. The clamping assembly is connected to the cover 300 and located at one side of the cover 300 close to the tub 200, i.e. located on the bottom surface of the cover 300. The clamping groove member 130 is connected to the tub 200 and located at a side of the tub 200 near the cover 300, i.e., on the top surface of the tub 200. When the clamping assembly is clamped with the clamping groove piece 130, the cover 300 is buckled on the barrel 200 and closes the opening of the barrel 200; when the clamping assembly is disengaged from the clamping groove member 130, the cover 300 can be rotated about the rotation axis such that the cover 300 is separated from the tub 200 to open the opening of the tub 200.

More specifically, the snap assembly includes a limit sleeve 110 and a movable snap 120. The limiting sleeve 110 is a cylindrical structure with a cavity inside, and the cavity forms an opening at two ends of the limiting sleeve 110 respectively. In some specific embodiments, the stop sleeve 110 is a cylindrical barrel. One end of the limiting sleeve 110 is fixedly connected to the cover 300, and the connection mode can be screw connection. The movable clamping piece 120 is movably arranged in the limit sleeve 110 along the first direction, and the movable clamping piece 120 is provided with a clamping part protruding out of the other end of the limit sleeve 110. The clamping groove member 130 is disposed on the tub 200, and a clamping groove is disposed on the clamping groove member 130.

In the process of pressing the cover 300, the limiting sleeve 110 and the movable clamping member 120 can relatively displace in the first direction, so that the movable clamping member 120 rotates around the central axis thereof. The clamping portion of the movable clamping piece 120 at the first angle can enter and exit the clamping groove, and the clamping portion of the movable clamping piece 120 at the second angle can be clamped with the clamping groove piece 130. Compared with the prior art that the cover body is pulled by a handle to open and close the cover body relative to the barrel body, the utility model can open and close the cover body 300 relative to the barrel body 200 by pressing the cover body 300 by arranging the push-spring mechanism 100 between the barrel body 200 and the cover body 300. The manner of pressing the opening and closing cover 300 requires less fine work on the hand, and even if the hand is injured, disabled or the user holding things in the hand is difficult, the operation is simple. In addition, compared with the handles protruding on the cover body in the prior art, the embodiment of the utility model omits the handles, is beneficial to improving the aesthetic degree of the cover device, and thus meets the aesthetic requirement of users on the cover device.

After the ejector mechanism 100 is mounted between the tub 200 and the lid 300, the initial angle of the movable clip 120 is the first angle, and if the lid 300 is to be fastened to the tub 200, the lid 300 may be pressed, and the clip portion of the movable clip 120 may smoothly enter and exit the slot through the opening of the slot until the end of the movable clip 120 contacts the bottom of the slot. In this process, before the movable clamping piece 120 does not contact the groove bottom, the movable clamping piece 120 and the limiting sleeve 110 can synchronously move, and relative movement between the two can not occur. After the end of the movable clamping piece 120 contacts with the bottom of the clamping groove, the pressing cover 300 is continuously pressed to enable the limiting sleeve 110 and the movable clamping piece 120 to relatively displace in the first direction, so that the movable clamping piece 120 can rotate around the central axis of the limiting sleeve, when the movable clamping piece 120 rotates from the first angle to the second angle, the clamping part of the movable clamping piece 120 at the second angle is clamped with the clamping groove piece 130, and therefore locking of the cover 300 and the barrel 200 is achieved.

In some specific embodiments, as shown in fig. 4 and fig. 5, in order to enable the movable clamping member 120 to be driven to rotate by using the movement of the limiting sleeve 110, a driving tooth surface 111 is disposed on an end surface of the other end, far from the cover 300, of the limiting sleeve 110, a driving shaft 122 is protruding from an outer wall surface of the movable clamping member 120, and when the limiting sleeve 110 and the movable clamping member 120 are relatively displaced in the first direction, the driving shaft 122 can move along the driving tooth surface 111 to rotate the movable clamping member 120. The mating structure of the drive tooth surface 111 and the drive shaft 122 is simple, the conversion between linear movement and rotation is smooth, and the manufacturing cost is low.

In some more specific embodiments, the driving shafts 122 are cylindrical, the number of driving shafts 122 is two, two driving shafts 122 are symmetrically disposed about the central axis of the movable clamping member 120, the number of driving tooth surfaces 111 may be plural, and the plurality of driving tooth surfaces 111 are disposed around the central axis of the limit sleeve 110 to form a ring-shaped tooth surface. It should be noted that the number of the driving tooth surfaces 111 is not particularly limited, and is flexibly set according to the requirement, but it is necessary to ensure that the movable joint 120 can be rotated by at least the difference between the first angle and the second angle when the driving shaft 122 moves from one end of one driving tooth surface 111 to the other end of the driving tooth surface 111. The number of the driving shafts 122 may be set to be more according to the requirement, and the driving force to the movable clamping member 120 can be increased by the cooperation of different driving shafts 122 and different driving tooth surfaces 111, so that the movable clamping member 120 is easier to rotate and is more stable in rotation.

In some specific embodiments, in order to implement the clamping and releasing of the clamping portion and the clamping groove member 130, as shown in fig. 5 and 6, the clamping portion includes a plurality of clamping blocks 121 disposed at intervals along the circumferential direction of the movable clamping member 120, an avoidance groove 126 is formed between two adjacent clamping blocks 121, the clamping groove member 130 includes a clamping column 131, and the clamping column 131 is disposed at an opening of the clamping groove.

The movable clamping piece 120 can rotate under the driving of the limit sleeve 110, so that the position of the avoidance groove 126 on the movable clamping piece 120 is changed, and when the avoidance groove 126 is opposite to the clamping column 131, the clamping column 131 can not influence the clamping part to enter and exit the clamping groove of the clamping groove piece 130; when the avoiding groove 126 and the clamping column 131 are dislocated, the top surface of the clamping block 121 entering the clamping groove can be abutted against the clamping column 131, so that the clamping part cannot be separated from the clamping groove, and the clamping connection between the movable clamping piece 120 and the clamping groove piece 130 is realized. The matching structure of the clamping blocks 121 and the clamping columns 131 is simple, the cost is low, and the clamping and releasing conversion is smooth.

In some more specific embodiments, with continued reference to fig. 5, the clamping block 121 is a toothed block, the top surface of the toothed block includes a first inclined surface 1211, a vertical surface 1212 and a second inclined surface 1213, which are sequentially connected, the inclined directions of the first inclined surface 1211 and the second inclined surface 1213 are the same, a tooth slot is formed between the first inclined surface 1211 and the vertical surface 1212, and the clamping post 131 can be clamped in the tooth slot, so as to improve the clamping strength. When the clamping portion and the clamping groove member 130 are released from clamping, the second inclined surface 1213 can be matched with the clamping post 131, so that the movable clamping member 120 can reversely rotate, and the clamping post 131 can enter the clamping groove.

In some more specific embodiments, with continued reference to fig. 6, the number of posts 131 is two, and the two posts 131 are coaxially disposed on either side of the bayonet of the slot member 130. The number of the avoidance grooves 126 is even, the avoidance grooves 126 are formed in a group of two pairs, and the two avoidance grooves 126 in each group of avoidance grooves 126 are symmetrically arranged about the axis of the movable clamping piece 120, so that the clamping strength can be improved.

It should be noted that, the plurality of clamping blocks 121 are uniformly distributed in the circumferential direction of the movable clamping member 120, one clamping groove is formed between every two clamping blocks 121, and the widths of the plurality of clamping grooves are the same. By providing the plurality of the clamping blocks 121 and forming a plurality of clamping grooves by using the plurality of the clamping blocks 121, the assembling difficulty can be reduced and the clamping strength can be improved. With continued reference to fig. 5, four clamping blocks 121 are provided, so that four clamping grooves are formed, the four clamping grooves are divided into two groups, and two clamping columns 131 included in one group of clamping columns 131 correspond to two clamping grooves included in any group of clamping grooves.

Further, in order to realize connection between the movable clamping member 120 and the limiting sleeve 110, a limiting structure is disposed in the limiting sleeve 110, one end of the movable clamping member 120 is disposed in the limiting sleeve 110 and abuts against the limiting structure, and the limiting structure can prevent the movable clamping member 120 from being separated from the other end of the limiting sleeve 110. That is, the limiting structure can only limit the movable clamping member 120 from being separated from the limiting sleeve 110, and does not affect the movement and rotation of the movable clamping member 120 in the limiting sleeve 110. The movable clamping piece 120 is rotatably connected in the limiting sleeve 110, can move in a cavity positioned on one side of the limiting structure close to the cover 300, and can drive the movable clamping piece 120 to rotate when the limiting sleeve 110 moves relative to the movable clamping piece 120.

In some specific embodiments, to achieve connection between the movable clip 120 and the stop sleeve 110, the stop structure disposed in the stop sleeve 110 is an annular protrusion disposed in the stop sleeve 110 and located in the middle of the stop sleeve 110.

Further, the movable clamping member 120 further includes a contact portion located at the other side of the clamping portion, and the contact portion is configured to contact with a bottom of the clamping groove member 130. Alternatively, the contact portion is hemispherical.

In some specific embodiments, as shown in fig. 7, the slot member 130 further includes a bottom plate 132 and two side plates 133 connected in a U-shape, the bottom plate 132 is fixedly connected to the tub 200, the two clamping columns 131 are respectively connected to the side plates 133, and the clamping columns 131 are disposed parallel to the bottom plate 132. The clamping groove member 130 has the advantages of simple structure, easy manufacture and good clamping effect.

Further, in order to make the clamping post 131 enter the tooth slot formed by the first inclined surface 1211 and the vertical surface 1212 more smoothly so as to complete the final clamping, and in order to make the clamping post 131 enter the avoidance slot 126 along the second inclined surface 1213 smoothly in the unlocking process, the pushing mechanism 100 further includes a first elastic body 140, the first elastic body 140 is disposed in the limit sleeve 110, one end of the first elastic body 140 is abutted with the inner wall surface of the cover 300, and the other end of the first elastic body 140 is abutted with the end of the movable clamping member 120 disposed in the limit sleeve 110.

The provision of the first elastic body 140 enables the clamping post 131 to more smoothly enter the tooth slot formed by the first inclined surface 1211 and the vertical surface 1212 to complete the final clamping. When the cover 300 needs to be unlocked, under the action of the second elastic body 150, the clamping post 131 passes over the vertical surface 1212 to reach the second inclined surface 1213, and the first elastic body 140 can drive the movable clamping member 120 to rotate continuously for a certain angle in the opposite direction, and thus the clamping post 131 smoothly enters the avoiding groove 126 along the second inclined surface 1213.
