Detailed Implementation
[0020] The present invention will be further described below with reference to the accompanying drawings.
[0021] like Figures 1 to 6As shown, one end of the spring wire assembly 4 is connected to the top plate 2, and the other end of the spring wire assembly 4 is connected to the bottom plate 3. A sleeve assembly 1 is sleeved on the outside of the spring wire assembly 4. The sleeve assembly 1 consists of several rectangular hollow tubes nested together. The innermost and outermost rectangular hollow tubes of the sleeve assembly 1 are connected to the top plate 2 and the bottom plate 3, respectively. Adjacent rectangular hollow tubes are connected by a limiting baffle assembly and a friction plate 5. The spring wire assembly 4 includes a spring wire, a spring wire pressing seat, a pressing plate, and a fixing seat. Spring wire pressing seats 4-2 are sleeved on both ends of the spring wire 4-1. The spring wire pressing seats 4-2 at both ends of the spring wire 4-1 are fixedly connected to the top plate 2 and the bottom plate 3 by pressing plates 4-3 and fixing seats 4-4, respectively.
[0022] The limiting baffle assembly includes an inner limiting baffle and an outer limiting baffle. The inner limiting baffle 6 has an "I"-shaped structure and is connected to the upper inner side of the rectangular hollow tube, with a gap between the inner limiting baffle 6 and the upper inner side of the rectangular hollow tube. The outer limiting baffle 7 has an "I"-shaped structure and is connected to the lower outer side of the rectangular hollow tube. The outer limiting baffle 7 and the inner limiting baffle 6 are nested and connected to each other.
[0023] Friction plate 5 is located around the lower end of the rectangular hollow tube.
[0024] There should be at least 5 rectangular empty tubes.
[0025] like Figure 1 , Figure 2 As shown, the extension range of the spring wire assembly 4 is 200-850mm, and the stroke is 650mm.
[0026] like Figure 3 As shown, the spring wire assembly 4 consists of 5 rectangular hollow tubes. The top of the uppermost rectangular hollow tube is welded to the top plate 2, and the bottom of the lowermost rectangular hollow tube is welded to the bottom plate.
[0027] like Figure 4 As shown, an inner limiting baffle 6 is fixed inside the upper opening of the four rectangular hollow tubes at the bottom of the spring wire assembly 4; a friction plate 5 and an outer limiting baffle 7 are fixed outside the lower opening of the four rectangular hollow tubes at the top of the spring wire assembly 4.
[0028] The function of friction plate 5 is: when the tube extends and retracts, there is a gap between the inner and outer tubes to prevent scratches on the tube surface; when the tube extends to its maximum height, the inner limit baffle 6 and the outer limit baffle 7 work together to stop the tube from detaching.
[0029] like Figure 5 , Figure 6 As shown, the two ends of the spring wire 8 are pressed into the spring wire clamping seat 9 for fixing on the clamping seat.
[0030] The upper end of the spring wire 4-1 has a spring wire clamping seat 4-2 that is clamped onto the upper clamping plate 4-3. The upper clamping plate 4-3 is fixed to the upper fixing seat 4-4 with M4 screws. The upper fixing seat 4-4 is fixed to the top plate 2. Similarly, the lower end of the spring wire 4-1 has a spring wire clamping seat 4-2 that is clamped onto the lower clamping plate 4-3. The lower clamping plate 4-3 is fixed to the lower fixing seat 4-4 with M4 screws. The lower fixing seat 4-4 is fixed to the bottom plate 3.
[0031] like Figure 7 , Figure 8 As shown, an electric height-adjustable table using a spring conduit is provided. The bottom of the tabletop 8 is connected to a socket 9, and an electric table cable tray 10 is provided below the tabletop 8. The bottom side of the tabletop 8 is connected to the electric table cable tray 10 through a spring conduit 4.
[0032] The two ends of the spring wire 4-1 of the spring wire assembly 4 are connected to the socket 9 and the electric table cable tray 10, respectively.
[0033] The spring wire assembly 4 of the electric height-adjustable desk is installed between the electric desk cable tray 10 and the electric desk tabletop 8. The spring wire 4-1 in the spring wire assembly 4 extends and retracts as the electric desk tabletop 8 is raised and lowered.
[0034] The electric height-adjustable desk has an electric power cord trough 10 between its legs. An external power cord enters the electric power cord trough 10 from the bottom of the electric height-adjustable desk. The lower end of the spring wire 4-1 is connected to the external power cord inside the electric power cord trough 10. The upper end of the spring wire 4-1 is connected to the socket 9 at the bottom of the tabletop 8 of the electric desk.
[0035] The use of spring wire assembly 4 makes the cables of the electric lifting table neat and aesthetically pleasing.
