Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In addition, technical solutions between various embodiments may be combined with each other, but must be realized by a person skilled in the art, and when the technical solutions are contradictory or cannot be realized, such a combination should not be considered to exist, and is not within the protection scope of the present invention.

The invention provides a support assembly which can ensure that a sealing element moves stably and avoid the sealing element from being blocked.

In an embodiment of the present invention, as shown in fig. 1 to 3, the rack assembly includes a support 100, a sealing member 200 and a driving assembly 300, wherein a mounting cavity 130 is formed in the support 100, the sealing member 200 is movably disposed on the top of the support 100 along a first direction, and the sealing member 200 is used for moving along the first direction to cover or open the mounting cavity 130; the driving assembly 300 is movably mounted on the supporting member 100 along a second direction, the driving assembly 300 is configured to move along the second direction to drive the sealing member 200 to move along the first direction, the second direction and the first direction form an included angle, and the included angle is greater than 0 degree and less than or equal to 90 degrees; a stopper 223 is disposed between the driving assembly 300 and the sealing member 200.

Specifically, when the angle between the first direction and the second direction is 0 °, that is, the driving force of the driving assembly 300 is the same as the moving direction of the sealing member 200, for example, both up and down directions, the driving force directly acts on the sealing member 200, and thus the sealing member 200 is easily shaken. In this embodiment, the contained angle of second direction and first direction equals 90, specifically, the second direction is the horizontal direction, first direction is vertical direction, so, the bracket component that this application provided can drive sealing member 200 through horizontal motion's drive assembly 300 and move along upper and lower direction, consequently, drive power indirectly acts on sealing member 200, and the drive power that sealing member 200 received is more steady, consequently can avoid sealing member 200 to take place to rock at the in-process of up-and-down motion, and then can avoid sealing member 200 to be died by the card at the in-process of motion.

In addition, because the limiting member 223 is arranged between the driving assembly 300 and the sealing member 200, the limiting member 223 can limit the relative position relationship between the driving assembly 300 and the sealing member 200, so that the sealing member 200 can move more stably under the driving action of the driving assembly 300, and the sealing member 200 can be prevented from being stuck due to shaking in the moving process.

Further, referring to fig. 1, 4 and 5, the installation structure of the limiting member 223 will now be described. In this embodiment, the limiting member 223 is disposed on the sealing member 200, specifically, the sealing member 200 includes a top sealing plate 210 and a bracket 220 respectively disposed at two sides of the top sealing plate 210 in the third direction, the limiting member 223 is disposed at one side of the bracket 220 far away from the top sealing plate 210, the driving assembly 300 includes a guide plate 310, and the guide plate 310 is in adaptive connection with the limiting member 223. In this way, when the guide plate 310 reciprocates in the second direction, the stopper 223 can increase the contact area between the guide plate 310 and the bracket 220, so that the movement of the bracket 220 along with the guide plate 310 can be more smooth.

It should be noted that, since the brackets 220 are disposed on both sides of the top sealing plate 210, the brackets 220 can smoothly pull down or lift up the top sealing plate 210, so that a good sealing effect between the top sealing plate 210 and the mounting cavity 130 can be ensured.

Further, referring to fig. 4 and fig. 5, a structure of the limiting member 223 is now described, in this embodiment, the limiting member 223 is formed with a limiting groove 223a, and the guide plate 310 is movably embedded in the limiting groove 223a along the second direction; the stopper groove 223a is used to stopper the guide plate 310 in the third direction. Since the stopper groove 223a may stopper the guide plate 310 in the third direction, the supporter 220 can smoothly move in the first direction when the guide plate 310 reciprocates in the second direction.

Specifically, the guide plate 310 is provided in a vertical long plate shape, a length direction of the guide plate 310 is the first direction, a width direction of the guide plate 310 is the second direction, and a thickness direction of the guide plate 310 is the third direction.

Further, with continued reference to fig. 4 and fig. 5, in order to achieve the limiting effect and prevent the limiting member 223 from forming resistance to the movement of the guide plate 310, in an embodiment of the present application, the guide plate 310 and the inner wall surface of the limiting groove 223a are disposed at an interval. Specifically, the limiting member 223 includes two clamping plates 223b arranged at intervals, the clamping plates 223b are arranged in a long strip shape, and the limiting groove 223a is formed between the two clamping plates 223 b. The two clamping plates 223b are respectively arranged on two sides of the guide plate 310 in the third direction, the inner surfaces of the two clamping plates 223b opposite to each other form the inner wall of the limiting groove 223a, and the guide plate 310 and the inner wall of the limiting groove 223a are arranged at intervals, so that the guide plate 310 can be prevented from contacting with the inner wall surface in the reciprocating motion process along the second direction, and the resistance of the guide plate 310 in the motion process can be reduced. As a preferable mode, the splint is in a slender trapezoid shape with the upper bottom larger than the lower bottom.

Further, as shown in fig. 2 and 3, considering that the position of the guide plate 310 in the vertical direction is always unchanged, the bracket 220 moves up and down under the driving action of the guide plate 310, and in order to avoid the stopper 223 from being disengaged from the guide plate 310 when moving upward along with the bracket 220, in this embodiment, the clamping plate 223b has a certain length, and specifically, the length of the clamping plate 223b in the first direction is greater than or equal to the displacement of the bracket 220 moving in the first direction. Thus, the size of the stopper groove 223a can be made larger than or equal to the displacement of the up-and-down movement of the bracket 220. Therefore, the bracket 220 can be positioned in the limiting groove 223a during the up-and-down movement, and the guide plate 310 is prevented from being separated from the limiting member 223.

In a preferred embodiment, the length of the clamping plate 223b in the first direction is greater than or equal to 1/2 times the width of the guide plate 310, and is smaller than the width of the guide plate 310.
