Detailed Description
The following are specific embodiments of the present invention and are further described with reference to the drawings, but the present invention is not limited to these embodiments.
Referring to fig. 1 to 4, the present invention discloses a stepless height adjuster, which comprises a guide rail 100 and a sliding assembly 200; the sliding assembly 200 is slidably disposed on the guide rail 100, no gear groove is disposed on the guide rail 100, a locking mechanism 210 is disposed in the sliding assembly 200, and the locking mechanism 210 can lock the height of the sliding assembly 200 on the guide rail 100; when the height needs to be adjusted, the locking mechanism 210 is unlocked to push the sliding assembly 200 to slide on the guide rail 100, when the sliding assembly 200 is adjusted to a preset height, the locking mechanism 210 is locked at a position of the sliding assembly 200 on the guide rail 100, and the sliding assembly 200 can be locked at any position of a preset sliding track in the guide rail 100, so that stepless height adjustment is realized.
The specific structure of the stepless height adjuster is as follows, please refer to fig. 1-4, the guide rail 100 includes a base 110 and side walls 120 disposed at two sides of the base 110;
the sliding assembly 200 comprises a locking mechanism 210, a sliding plate assembly 220 and an automatic resetting pressing piece 230; the pressing member 230 is disposed on the sliding plate assembly 220, and the two side walls 120 of the guide rail 100 limit the sliding plate assembly 220 to only slide along the length direction of the guide rail 100; the locking mechanism 210 includes at least one locking block 211 movably contacting the base 110, and the pressing member 230 is configured to drive the locking block 211 away from the base 110 to unlock the sliding assembly 200.
The length direction of the guide rail 100 refers to a height adjustment direction of the stepless height adjuster.
In a general case (when no one presses the pressing member 230), the locking mechanism 210 is in a locking state, and locks the position of the sliding assembly 200 on the guide rail 100, and when the pressing member 230 is pressed, the pressing member 230 drives the locking block 211 not to contact with the base 110, so that no friction is generated between the base 110 and the locking block 211, and at this time, the sliding assembly 200 can be pushed to slide on the guide rail 100 at will.
The locking mechanism 210 further includes a moving member 212, the moving member 212 is connected to the pressing member 230, the moving member 212 is elastically connected to the two locking blocks 211, and the number of the two locking blocks 211 is respectively set at two ends of the moving member 212.
In this embodiment, the pressing piece is hinged to the moving piece 212, when the moving piece 212 is pressed, the moving piece 212 moves in a direction away from the guide rail 100, the moving piece 212 drives the locking piece 211 to move in a direction away from the guide rail 100, and when the pressing piece 230 is pressed, the locking mechanism 210 can be unlocked.
In this embodiment, the locking block 211 is elastically connected to the moving member 212, so that the locking block 211 is in a floating state, and when the position of the sliding assembly 200 on the guide rail 100 is adjusted upward, stepless height adjustment can be realized without unlocking; when the height of the sliding assembly 200 is adjusted downwards, the sliding assembly needs to be unlocked to realize stepless height adjustment; the locking piece 211 is wedge-shaped, the upper end width of locking piece 211 is less than the lower extreme width of locking piece 211, slide plate subassembly 220 be equipped with the spacing groove 220a that the locking piece 211 shape matches, be equipped with the first plane that has the wedge degree in the locking piece 211, spacing groove 220a be provided with first plane complex second plane 220 b.
The first plane is an inclined plane, and the first plane with the lateral wall 120 of guide rail 100 has an contained angle, the first plane is connected the upper end and the lower extreme of lock block 211, second plane 220b is the inclined plane, connects the upper end and the lower extreme of spacing groove 220 a.
When the sliding assembly 200 is adjusted upwards, the friction force applied to the locking block 211 is downward, because the locking block 211 is in a floating state, the locking block 211 can slightly move downward relative to the limiting groove 220a in the limiting groove 220a, the limiting groove 220a is wide downward and narrow inward, the locking block 211 cannot be locked, the friction force between the locking block 211 and the guide rail 100 is reduced along with the downward movement of the locking block 211, and finally, the relative movement can be generated, so that the height adjuster does not need to be unlocked when being adjusted upwards.
When down heightening, need the unblock, during down height-adjusting's height, the frictional force that locking block 211 received up, because of locking block 211 is unsteady, locking block 211 has relative spacing groove 220a tendency of up-moving in spacing groove 220a, spacing groove 220a narrow down, locking block 211 is relative when spacing groove 220a up-moving, can be hindered its up-moving by the locked position (spacing groove 220a can hinder), the relative position of locking block 211 in spacing groove 220a is locked, locking block 211 with guide rail 100's frictional force can not diminish, consequently, when down heightening, needs the unblock, make locking block 211 with guide rail 100 contactless realizes down heightening again.
In order to increase the friction force, the surface of the locking block 211 contacting with the base 110 is provided with a protrusion, and the base 110 is made of an orthotropic material.
The sliding plate assembly 220 includes a sliding block 221 and a fixing member 222, wherein the fixing member 222 is fixedly connected to the sliding block 221, and the fixing member 222 and the sliding block 221 are slidable together.
The locking mechanism 210 is further provided with at least one elastic member 213, the moving member 212 is disposed between the sliding block 221 and the fixed member 222, and two ends of the elastic member 213 respectively abut against the fixed member 222 and the moving member 212.
The elastic member 213 is configured to provide a pre-pressure to the locking block 211, so as to improve the stability of the locking mechanism 210 with respect to the guide rail 100 through friction.
The slider 221 is provided with a mounting groove 221a, and the moving member 212 is disposed in the mounting groove 221 a.
The both sides of pressing piece 230 all set up the cover post 231, every all be provided with torsional spring 232 on the cover post 231, torsional spring 232 still with slide subassembly 220 links to each other.
In this embodiment, the torsion spring 232 is provided to restore the pressing member 230 after being pressed.
The fixing member 222 is provided with a receiving groove 222a receiving the pressing member 230, and the pressing member 230 is hinged to the fixing member 222.
Each side wall 120 is provided with a limiting portion 121, the limiting portion 121 extends from one side of the base 110 where the limiting portion is located to the opposite side, and two sides of the sliding assembly 200 are respectively provided with a limiting space for the two limiting portions 121 to extend into.
The invention discloses a stepless height adjuster, which can adjust height in a stepless way, realize locking of a sliding assembly 200 through static friction of a locking block 211 and a guide rail 100, release the position locking of a locking mechanism 210 and the sliding assembly 200 by pressing a pressing piece 230 when adjusting the height downwards, and directly push the sliding assembly 200 to realize the height upwards without unlocking operation when adjusting the height upwards.
