Description

Technical Field

[0001] The invention relates to the technical field of operating tables, and in particular to a telescopic outer cover of an operating table column. Background Art

[0002] The operating table is a platform for performing surgical operations and anesthesia. The surgical assistant adjusts the operating table to the required position according to the surgical requirements, so that the surgical field is fully exposed, and it is also convenient for the patient to be anesthetized and infused, so that the operation can be carried out smoothly. It is usually composed of a bed body (including a support part, a transmission part and an electric control part) and accessories. The support part usually includes three parts: a table top (various support plates), a lifting column and a base. According to the transmission principle, it can be divided into three transmission structure forms: hydraulic, mechanical and pneumatic. The headboard, backboard, legboard and table top are adjustable.

[0003] An outer cover surrounding the lifting column is usually provided outside the lifting column. Since the length of the lifting column changes, the length of the outer cover also needs to change accordingly. Therefore, in the prior art, the telescopic outer cover of the operating table is usually composed of multiple telescopic joints. Although each telescopic joint is made of metal, each telescopic joint is usually insulated, making it difficult to effectively remove static electricity. Summary of the invention

[0027] The technical solution of the present invention is further described in detail below in conjunction with preferred embodiments and the accompanying drawings.

[0028] like Figure 1 As shown, the telescopic outer cover of the operating bed column corresponding to a preferred embodiment of the present invention is composed of a plurality of telescopic sections nested in each other. In this embodiment, the number of telescopic sections is four, and the connection relationship between two adjacent telescopic sections is basically the same. The connection relationship is introduced below by taking the first telescopic section 1 and the second telescopic section 2 adjacent thereto as an example.

[0029] like Figure 2 As shown, the cross-sections of the first telescopic section 1 and the second telescopic section 2 are rectangular, and the second telescopic section 2 is arranged inside the first telescopic section 1 .

[0030] like Figures 3 to 5 As shown, an upwardly bent flange 11 is provided on the inner side surface 10 of the first telescopic section 1, and a U-shaped slot 12 is formed between the flange 11 and the inner side surface 10. A plastic block 13 is provided in the slot 12, and the plastic block 13 is provided with a head 130 that contacts the outer side surface 20 of the second telescopic section 2. When the first telescopic section 1 rises, the plastic block 13 rises with the first telescopic section 1 and slides along the outer side surface 20. Preferably, the plastic block 13 is made of self-lubricating plastic.

[0031] The flange 11 is preferably arranged at the bottom of the inner side 10 .

[0032] like Figure 6 and Figure 7 As shown, a barb 21 is provided on the outer side 20 of the second telescopic section 2, and preferably the barb 21 is provided on the top of the outer side 20. When the first telescopic section 1 moves upward until the head 130 contacts the barb 21, the head 130 will drive the second telescopic section 2 to move upward.

[0033] The barb 21 is preferably an outer flange that is bent downward at the top of the outer side surface 20 , and 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 .

[0034] When the lifting column pushes the table top up, it also drives the outermost telescopic section up. When the outermost telescopic section rises to the point where its plastic block contacts the barb of its adjacent telescopic section, the adjacent telescopic section will be driven upward, and so on. Each telescopic section will gradually move upward from outside to inside.

[0035] Preferably, the four inner sides of the first telescopic section 1 are all provided with plastic blocks 13, and the number of plastic blocks 13 is multiple, and the second telescopic section 2 can be reliably positioned in the first telescopic section 1 to prevent tilting by the plastic blocks 13 abutting against the four sides of the second telescopic section 2. Accordingly, the second telescopic section 2 can be provided with barbs 21 matching the plastic blocks 13.

[0036] In the above structure, since the telescopic joints are separated by plastic blocks 13, the telescopic joints are insulated from each other, making it difficult to remove static electricity from the device. To this end, the telescopic cover of the operating bed column of the present invention further includes an elastic card 3 arranged on the second telescopic joint 2.

[0037] like Figures 8 to 10 As shown, the elastic card 3 is formed by bending an elastic metal sheet in one piece, and includes a clamping portion 31 for clamping the side plate 23 of the second telescopic section 2 and an abutting sheet 34 for pressing the inner side 10 of the first telescopic section 1. Specifically, the clamping portion 31 is formed by a first sheet 32 ​​and a second sheet 33, and the abutting sheet 34 is connected to the second sheet 33.

[0038] A long hole 24 is provided on the outer side surface 20, and the clamping portion 31 is clamped on the long hole 24. The abutting sheet 34 forms an angle with the outer side surface 20 and is elastically pressed on the inner side surface 10. Since the elastic card 3 is elastic, the elastic card 3 can effectively conduct the first telescopic section 1 and the second telescopic section 2 regardless of whether the outer cover is in a static state or a moving state. It can be understood that an elastic card is provided between each adjacent telescopic section so that each telescopic section is mutually conductive, which is conducive to eliminating the influence of static electricity.

[0039] It is understandable that the elastic card 3 can also be connected to the first telescopic section 1 and abut against the outer side surface 20 of the second telescopic section 2, and the same effect can be achieved. When the elastic card 3 is connected to the first telescopic section 1, it is preferably installed near the bottom; when the elastic card 3 is connected to the second telescopic section 2, it is preferably installed near the top.

[0040] The telescopic outer cover of the operating bed column of the present invention has a simple structure and is reliable to use. Elastic cards are arranged between the telescopic joints, so that the telescopic joints can be connected to each other, which is beneficial to eliminate the influence of static electricity.

[0041] It should be pointed out that the above preferred embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
