Detailed Description

In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the invention easy to understand, the invention is further explained below by combining the specific drawings.

Referring to fig. 1 to 5, a quick-connect assembly between a table top and a table frame beam is shown, which includes a quick-connect seat 100, a circular connecting tab 200 and a rotating member 300.

The quick clamping seat 100 is detachably mounted on a table frame beam (not shown in the figure), a semicircular step 110 is formed on the upper end face 101 of the quick clamping seat 100, a semicircular limiting groove 120 is formed between the semicircular step 110 and the upper end face 101 of the quick clamping seat 100, and a rotating through hole 130 is formed on the outer side of the semicircular limiting groove 120 on the upper end face of the quick clamping seat 100. In addition, an arc groove 140 matched with the table frame beam is formed on the lower end surface of the quick clamping seat 100, and clamping seat mounting through holes 150 are respectively formed on two sides of the quick clamping seat 100, which are positioned on the semicircular limiting groove 120; during installation, the quick clamping seat 100 is screwed into a screw hole pre-formed in the table frame beam after passing through the two clamping seat installation through holes 150 of the quick clamping seat 100 by using two screws through an arc-shaped groove formed on the lower end surface of the quick clamping seat 100, so that the quick clamping seat 100 is installed on the table frame beam.

The circular clip sheet 200 is detachably mounted on the lower plate surface of the desk plate and corresponds to the quick clip seat 100, and the outer peripheral surface of the circular clip sheet 200 is a truncated cone-shaped limiting inclined surface 210. A card connecting piece mounting through hole 220 is formed at the center of the circular card connecting piece 200. During installation, the circular clamping sheet 200 is arranged on the lower plate surface of the desk plate, and then screws are adopted to penetrate through the clamping sheet installation through holes 220 of the circular clamping sheet 200. And then screwed into a screw hole formed in the lower plate surface of the table plate in advance, so that the circular clamping piece 200 is mounted on the lower plate surface of the table plate. In order to adjust the gap between the circular locking piece 200 and the table, a circular elastic pad 230 is disposed between the upper end surface of the circular locking piece 200 and the lower plate surface of the table.

The rotating member 300 has a rotating disc portion 310 and a handle portion 320, a rotating convex column 311 is formed on the lower side surface of the rotating disc portion 310, the rotating convex column 311 is rotatably installed in the rotating through hole 130 of the quick clamping seat 100, so that the rotating member 300 rotates along the rotating convex column 311, and a limiting inclined plane 312 which is mutually matched with the truncated cone-shaped limiting inclined plane 210 for limiting is formed on the outer side surface of the rotating disc portion 310.

During assembly, the circular clamping sheet 200 is aligned with the semicircular limiting groove 120 of the quick clamping seat 100, the circular clamping sheet 200 is pushed into the semicircular limiting groove 120 of the quick clamping seat 100, and then the handle part 320 rotates the turntable part 310 anticlockwise, so that the limiting inclined surface 312 on the turntable part 310 presses the truncated cone-shaped limiting inclined surface 210 on the circular clamping sheet 200, as shown in fig. 4 and 5, and the circular clamping sheet 200 is limited in the semicircular limiting groove 120 of the quick clamping seat 100.

In order to further position the rotating member 300, a positioning blind hole 160 is formed between the rotating through hole 130 and the semicircular limiting groove 120 on the upper end surface 101 of the quick clamping seat 100, a positioning small cylinder 400 is installed in the positioning blind hole 160, a small spring 410 is installed below the positioning small cylinder 400 in the positioning blind hole 160, the upper end of the small spring 410 abuts against the lower end surface of the positioning small cylinder 400, and the lower end of the small spring abuts against the bottom surface of the positioning blind hole 160 and is used for jacking up the positioning small cylinder 400. An arc-shaped positioning groove 313 is formed on the outer side surface of the turntable 310 of the rotary member 300.

When the rotating member 300 is at the initial position, i.e., the position shown in fig. 1 and 2, the positioning small cylinder 400 is pushed up by the small spring 410, and a part of the positioning small cylinder is inserted into the circular arc positioning groove 313 of the rotating member 300, and the rest is located outside the circular arc positioning groove 313, since the rotating member 300 is pushed up by the positioning small cylinder 400, the rotating member 300 cannot rotate. When the circular engagement piece 200 enters the semicircular spacing groove 120 of the quick engagement seat 100, the outer edge of the circular engagement piece 200 presses on the top surface of the positioning small cylinder 400 exposed out of the circular arc positioning groove 313, and presses the positioning small cylinder 400 into the positioning blind hole 160, at this time, the rotation member 300 can rotate.

In addition, a torsion spring 330 is sleeved on the outer peripheral surface of the rotating boss 311 formed on the rotating disk portion 310 of the rotating member 300. When no external force is applied to the rotating member 300, the torsion spring 330 causes the rotating member 300 to rotate toward the initial position, and when the positioning small cylinder 400 is pushed into the circular arc-shaped positioning groove 313 of the rotating member 300, the rotating member 300 stops rotating.

The foregoing shows and describes the general principles and broad features of the present invention and advantages thereof. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed.
