Description

Technical Field

[0001] The utility model relates to a guide rail, in particular to a slide rail capable of quickly adjusting the height of a drawer panel. Background Art

[0002] When installing a drawer, due to the positioning dimensions of the drawer and the cabinet during installation, it is easy to produce assembly errors in the up and down directions between the drawer and the cabinet. At this time, the installation height of the drawer needs to be adjusted. The traditional drawer height adjustment is mainly to adjust the installation height between the drawer panel and the slide rail. The slide rail is threaded with an adjustment stud. By turning the adjustment piece on the adjustment stud, the height of the adjustment stud against the drawer panel is adjusted. However, this method requires the drawer to be disassembled for adjustment, and the adjustment piece is small and difficult to turn. Therefore, there is an urgent need for a slide rail that can quickly and conveniently adjust the height of the drawer panel. Utility Model Content

[0003] The utility model aims to provide a slide rail capable of quickly adjusting the height of a drawer panel, so as to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0004] The solution of the utility model to solve the technical problem is:

[0005] 4. The repairing kit for automotive dents, according to claim 1, wherein the at least one wheel is connected to the side of the foot stand, and the wheelchair accessible by the foot is connected to a plurality of wheeled accessories, wherein the at least one wheel is adapted to engage with the foot and engage with the foot of the foot.

[0006] The technical solution has at least the following beneficial effects: The fixed rail is used to be installed inside the cabinet, and the movable rail is used to be installed on the bottom side of the drawer. During installation, when there is an assembly gap between the drawer and the cabinet in the up and down direction, rotate the adjustment shaft to drive the support block on the adjustment shaft to rotate synchronously. When it is necessary to raise the drawer, gradually rotate the support block upwards out of the avoidance opening. Since the center of the arc of the arc-shaped support surface on the top side of the support block deviates from the adjustment shaft, as the support block is gradually rotated, the height protruding upwards from the avoidance opening also gradually increases. Use the arc-shaped support surface to abut against the bottom surface of the drawer, and the positioning groove itself can stably support and wrap the positioning wheel. When the adjustment wheel rotates, the elastic protrusion is elastically squeezed and deformed, so as to change the cooperation with different adjustment grooves, and maintain the positioning state of the adjustment wheel by using the elastic protrusion, so as to gradually raise the drawer. When it is necessary to lower the drawer, rotate the support block into the avoidance opening. As the support block is gradually rotated, the height of the arc-shaped support surface lifting the bottom surface of the drawer gradually decreases. Similarly, at this time, the elastic protrusion is elastically squeezed and deformed, maintaining the positioning state of the elastic protrusion on the adjustment wheel. In this way, the height of the arc-shaped support surface lifting the drawer can be directly changed by rotating the adjustment shaft, so as to quickly and conveniently adjust the installation height of the drawer and improve the installation efficiency of the drawer.

[0007] As a further improvement of the above technical solution, the end cover is made of an elastic material. When the positioning wheel rotates, it will squeeze the elastic protrusion. At this time, the entire elastic end cover can also be elastically deformed by extrusion, so as to change the position of the elastic protrusion positioned in the adjustment groove.

[0008] As a further improvement of the above technical solution, a limiting groove is formed in the movable rail for the end cover. The limiting groove and the positioning groove are arranged along the length direction of the adjustment shaft. Two limiting ribs are arranged along the length direction in the limiting groove. A support wheel is arranged on the adjustment shaft. The support wheel is located in the limiting groove. The support wheel and the adjustment wheel are respectively located on one side away from each other of the two limiting ribs. Through the cooperation of the support wheel and the limiting groove and the cooperation of the adjustment wheel and the positioning groove on the adjustment shaft, the adjustment shaft can be stably rotated in the movable rail, and the limiting ribs arranged in the limiting groove can limit the support wheel and the adjustment wheel along the length direction of the adjustment shaft to prevent the adjustment shaft from slipping out of the movable rail outward, and improve the stability of the rotational connection of the adjustment shaft.

[0009] As a further improvement of the above technical solution, a rotation-stopping protrusion is arranged on the outer peripheral wall of the adjustment wheel, and the rotation-stopping protrusion extends into the avoidance opening. When the support wheel rotates, when the rotation-stopping protrusion rotates in the avoidance opening, the rotation-stopping protrusion abuts against both sides of the avoidance opening, thereby limiting the rotation stroke of the support wheel.

[0010] As a further improvement of the above technical solution, a handle is connected to one end of the adjusting shaft located outside the movable rail. When it is necessary to rotate the adjusting shaft, force can be applied to the handle, which can improve the convenience of applying force to rotate the adjusting shaft and enhance the user experience.

[0011] As a further improvement of the above technical solution, the end cover and the movable rail are detachably connected. The end cover can be detached from the movable rail, which is convenient for combination and replacement. Especially for different height adjustment requirements, end covers of different sizes and specifications can be combined to improve the flexibility of use.

[0012] As a further improvement of the above technical solution, a hook is provided on the top side of the end of the movable rail away from the end cover. When installing the movable rail on the drawer, the hook can be installed on the side of the drawer and hooked tightly for positioning, so as to realize the quick installation of the movable rail.

[0013] As a further improvement of the above technical solution, the present utility model further includes a bolt. The bolt is inserted through the movable rail in the width direction of the movable rail, and one end of the bolt extends out of the movable rail. After adjusting the distance between the movable rail and the drawer, the bolt can be inserted along the width direction of the movable rail, and the end of the bolt extending out of the movable rail can be further inserted into the side wall of the drawer to realize the stable connection between the movable rail and the drawer.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, other embodiments obtained by those skilled in the art without creative efforts shall fall within the scope of protection of the present utility model. In addition, all the connection relationships mentioned in the text do not simply refer to the direct connection of components, but refer to the formation of a more optimal connection structure by adding or reducing connection accessories according to specific implementation situations. The various technical features in the present invention can be combined interactively without conflicting with each other.

[0020] Referring to Figure 1 With Figure 2 , a slide rail capable of quickly adjusting the height of a drawer panel, comprising: a fixed rail 1; a movable rail 2, at the end of which an adjusting shaft 3 is rotatably connected, one end of the adjusting shaft 3 extends into the movable rail 2 and is connected with an adjusting wheel 31, a plurality of adjusting grooves 32 are circumferentially arranged on the outer periphery of the adjusting wheel 31, a support block 33 is arranged on the adjusting shaft 3, an arc-shaped support surface 34 is formed on the top side of the support block 33, the center of the arc of the arc-shaped support surface 34 deviates from the adjusting shaft 3, an avoidance opening is arranged at the position of the movable rail 2 corresponding to the support block 33, and the adjusting shaft 3 can rotate to drive the arc-shaped support surface 34 to enter and exit the avoidance opening; an end cover 4, which is connected to one end of the movable rail 2, a positioning groove 41 is formed in the end cover 4 in the movable rail 2, a plurality of elastic protrusions 42 are arranged on the inner side of the positioning groove 41, the adjusting wheel 31 is located in the positioning groove 41, and the plurality of elastic protrusions 42 are respectively connected and matched in the plurality of adjusting grooves 32.

[0021] In the slide rail capable of quickly adjusting the height of the drawer panel herein, the fixed rail 1 is used to be installed inside the cabinet body, and the movable rail 2 is used to be installed on the bottom side of the drawer. During installation, when there is an assembly gap between the drawer and the cabinet body in the up and down direction, rotate the adjusting shaft 3 to drive the support block 33 on the adjusting shaft 3 to rotate synchronously. When it is necessary to raise the drawer, gradually rotate the support block 33 upward out of the avoidance opening. Since the center of the arc of the arc-shaped support surface 34 on the top side of the support block 33 deviates from the adjusting shaft 3, as the support block 33 is gradually rotated, the height protruding upward from the avoidance opening also gradually increases. Use the arc-shaped support surface 34 to abut against the bottom surface of the drawer, and the positioning groove 41 itself can stably support and wrap the positioning wheel. When the adjusting wheel 31 rotates, the elastic protrusion 42 is elastically squeezed and deformed, so as to cooperate with different adjusting grooves 32, and maintain the positioning state of the adjusting wheel 31 by using the elastic protrusion 42, so as to gradually raise the drawer. When it is necessary to lower the drawer, rotate the support block 33 into the avoidance opening. As the support block 33 is gradually rotated, the height of the arc-shaped support surface 34 lifting the bottom surface of the drawer gradually decreases. Similarly, at this time, the elastic protrusion 42 is elastically squeezed and deformed, and the positioning state of the elastic protrusion 42 on the adjusting wheel 31 is maintained. In this way, the height of the arc-shaped support surface 34 lifting the drawer can be directly changed by rotating the adjusting shaft 3, so as to quickly and conveniently adjust the installation height of the drawer and improve the installation efficiency of the drawer.

[0022] In the above embodiment, an elastic material can be compounded in the positioning groove 41 to form the elastic protrusion 42. In order to further improve the elastic deformation avoidance effect on the elastic protrusion 42, in this embodiment, the end cover 4 is made of an elastic material. When the positioning wheel rotates, it will squeeze the elastic protrusion 42. At this time, the entire elastic end cover 4 can also be elastically squeezed and deformed, so as to change the position of the elastic protrusion 42 positioned in the positioning groove 41.

[0023] For the implementation manner in which the adjusting shaft 3 is rotatably connected to the movable shaft, as Figure 3 shown, the end cover 4 forms a limiting groove 43 in the movable rail 2. The limiting groove 43 and the positioning groove 41 are arranged along the length direction of the adjusting shaft 3. Two limiting ribs 44 are arranged along the length direction in the limiting groove 43. A support wheel 35 is arranged on the adjusting shaft 3. The support wheel 35 is located in the limiting groove 43. The support wheel 35 and the adjusting wheel 31 are respectively located on one side of the two limiting ribs 44 away from each other. Through the cooperation of the support wheel 35 and the limiting groove 43 and the cooperation of the adjusting wheel 31 and the positioning groove 41 on the adjusting shaft 3, the adjusting shaft 3 can be stably rotated in the movable rail 2, and the limiting ribs 44 arranged in the limiting groove 43 can limit the support wheel 35 and the adjusting wheel 31 along the length direction of the adjusting shaft 3 to prevent the adjusting shaft 3 from slipping out of the movable rail 2 outward, and improve the stability of the rotational connection of the adjusting shaft 3.

[0024] To limit the excessive rotation of the adjusting wheel 31, in this embodiment, a rotation-stopping protrusion 36 is provided on the outer peripheral wall of the adjusting wheel 31, and the rotation-stopping protrusion 36 extends into the avoidance opening. When the supporting wheel 35 rotates, when the rotation-stopping protrusion 36 rotates in the avoidance opening, the rotation-stopping protrusion 36 abuts against both sides of the avoidance opening, thereby limiting the rotation stroke of the supporting wheel 35.

[0025] In some embodiments, a handle 38 is connected to one end of the adjusting shaft 3 located outside the movable rail 2. When it is necessary to rotate the adjusting shaft 3, force can be applied to the handle 38, so that the convenience of applying force to rotate the adjusting shaft 3 can be improved, and the use experience can be improved.

[0026] In some embodiments, the end cap 4 and the movable rail 2 are detachably connected. The end cap 4 can be detached from the movable rail 2, so as to facilitate combination and replacement. Especially for different height adjustment requirements, end caps 4 of different size specifications can be combined to improve the flexibility of use.

[0027] In some embodiments, a hook 21 is provided on the top side of the end of the movable rail 2 away from the end cap 4. When the movable rail 2 is installed on the drawer, the hook 21 can be installed on the side of the drawer and hooked tightly for positioning, so that the quick installation of the movable rail 2 can be realized.

[0028] As a further improvement of the above technical solution, the present invention further includes a bolt 5. The bolt 5 is inserted through the movable rail 2 in the width direction of the movable rail 2, and one end of the bolt 5 extends out of the movable rail 2. After the distance between the movable rail 2 and the drawer is adjusted, the bolt 5 can be inserted along the width direction of the movable rail 2, and the end of the bolt 5 extending out of the movable rail 2 can be further inserted into the side wall of the drawer to realize the stable connection between the movable rail 2 and the drawer.

[0029] The above has specifically described the preferred embodiments of the present invention, but the present invention is not limited to the above embodiments. Those skilled in the art can also make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
