Detailed ways

The technical solution of the present invention is further described in non-limiting detail below in conjunction with the preferred embodiments and the accompanying drawings.

As shown in FIG. 1 , corresponding to a preferred embodiment of the present invention, a telescopic cover of an operating bed column is composed of a plurality of telescopic joints nested in each other. In this embodiment, the number of telescopic joints is four, and two adjacent ones The connection relationship between the expansion joints is basically the same, and the connection relationship between the first expansion joint 1 and the adjacent second expansion joint 2 is described below as an example.

As shown in FIG. 2 , the cross-sectional shapes of the first telescopic section 1 and the second telescopic section 2 are rectangular, and the second telescopic section 2 is inserted inside the first telescopic section 1 .

As shown in FIGS. 3 to 5 , the inner side 10 of the first telescopic joint 1 is provided with an upwardly bent flange 11 , and a U-shaped clamping slot 12 is formed between the flange 11 and the inner side 10 . The plastic block 13 is clamped, and the plastic block 13 is provided with a head 130 in contact with the outer side surface 20 of the second telescopic section 2. When the first telescopic section 1 rises, the plastic block 13 goes up with the first telescopic section 1, and slide along the outer side surface 20, preferably, the plastic block 13 is made of self-lubricating plastic.

The flange 11 is preferably arranged at the bottom of the inner side 10 .

As shown in FIGS. 6 and 7 , barbs 21 are provided on the outer side 20 of the second telescopic section 2 . Preferably, the barbs 21 are arranged on the top of the outer side 20 . When the first telescopic section 1 ascends to the head 130 and the barb When the hook 21 is in contact, the head 130 will drive the second telescopic section 2 upward.

The barb 21 is preferably a valgus that is bent downward at the top of the outer side surface 20 , a U-shaped hook groove 22 is formed between the barb 21 and the outer side surface 20 , and the head 130 can extend into the hook groove 22 .

When the lifting column pushes the table to rise, it drives the outermost expansion joint to rise at the same time. When the outermost expansion joint rises until its plastic block touches the barb of its adjacent expansion joint, the adjacent expansion joint will be driven upward. By analogy, each expansion joint will gradually ascend from outside to inside.

Preferably, the four inner sides of the first telescopic section 1 are provided with plastic blocks 13, and the number of plastic blocks 13 is multiple. 2. Reliably positioned in the first telescopic section 1 to prevent tilting. Correspondingly, the second telescopic section 2 can be provided with barbs 21 matched with the plastic blocks 13 .

In the above structure, since the expansion joints are separated by the plastic blocks 13, the expansion joints are insulated from each other, and it is difficult to remove the static electricity of the equipment. Therefore, the telescopic cover of the operating bed column of the present invention further includes an elastic card 3 arranged on the second telescopic section 2 .

As shown in FIGS. 8 to 10 , the elastic card 3 is integrally formed by bending an elastic metal sheet, and includes a clamping portion 31 for clamping the side plate 23 of the second telescopic section 2 and a clamping portion 31 for pressing the first telescopic section 2 The abutting piece 34 of the inner side surface 10 of the segment 1 . Specifically, the clamping portion 31 is formed by a first sheet body 32 and a second sheet body 33 , and the abutting sheet body 34 is connected with the second sheet body 33 .

The outer side 20 is provided with a long hole 24 , the clamping portion 31 is clamped on the long hole 24 , and the contact piece 34 forms an angle with the outer side 20 and elastically presses on the inner side 10 . Since the elastic card 3 has elasticity, the elastic card 3 can effectively make the first telescopic section 1 and the second telescopic section 2 conduct conduction regardless of whether the outer cover is in a static state or a moving state. It can be understood that elastic cards are arranged between adjacent expansion joints, so that the expansion joints are connected to each other, which is beneficial to eliminate the influence of static electricity.

It can be understood that the elastic card 3 can also be connected to the first telescopic joint 1 and abutted on the outer side surface 20 of the second telescopic joint 2, and the same effect can also be achieved. When the elastic card 3 is connected to the first expansion joint 1, it is preferably installed at a position close to the bottom; when the elastic card 3 is connected to the second expansion joint 2, it is preferably installed at a position close to the upper part.

The telescopic cover of the upright column of the operating bed of the invention is simple in structure and reliable in use, and elastic cards are arranged between the telescopic joints, so that the telescopic joints can be connected to each other, and the influence of static electricity can be eliminated.

It should be pointed out that the above-mentioned preferred embodiment is only to illustrate the technical concept and characteristics of the present invention, and its purpose is to enable those who are familiar with the technology to understand the content of the present invention and implement it accordingly, and cannot limit the present invention. protected range. All equivalent changes or modifications made according to the spirit of the present invention should be included within the protection scope of the present invention.
