Detailed description of the invention
Below in conjunction with drawings and Examples
The invention will be further described:
As shown in Figure 1-Figure 3, a kind of adjustable up-down seat, comprises lifting rail chair 1 and elevating lever 2, and lifting rail chair 1 comprises first rail cover the 11, second track 12 and the 3rd track 13, first rail cover, the second track and the 3rd track and to be formed in one structure.First rail overlaps 11 tops and offers the first perforation, and the radius of the first perforation is 3-4cm; In the present embodiment, the radius of the first perforation is 2.5cm, effectively can improve the stability of device, and the surrounding along the first perforation is provided with four the first fixing holes; Be provided with locating piece 41 and cover plate 43 in first rail cover 11, the radius of cover plate 43 is 3.5-4cm, and the radius of the present embodiment cover plate 43 is 3.8cm, effectively can improve the stability of device; The center of cover plate 43 offers the second perforation, offers four the first fixing holes around the second perforation; Locating piece 41 is provided with drive link 21, drive link 21 extends the top of the first rail cover 11 through the second perforation and the first perforation; Head rod 22 is provided with in first rail cover 11, the top of head rod 22 offers storage tank 42, the size of storage tank 42 and the size of locating piece 41 adapt, and locating piece 41 is arranged in storage tank 42, offer four the second fixing holes around storage tank 42;
Four the first fixing holes are equipped with screw, and each screw is simultaneously through four the first fixing holes and four the second fixing holes; Head rod 22 is hollow-core construction, and the lower inner wall of head rod 22 is provided with the first internal thread 201, and the bottom of head rod 22 offers the first opening 203;
The top of the second rail cover 12 is set in the bottom of the first rail cover 11, is provided with on the second connecting rod 101, second connecting rod 101 and is provided with the first external screw thread 202 and the second internal thread 103 in the second rail cover 12; The bottom of the second rail cover 12 offers the 3rd bottom of boring a hole the 112, second rail cover 12 and is provided with location-plate 111, and the below of the second rail cover 12 is provided with clamping ring 3; The center of clamping ring 3 offers the 5th perforation, and the radius of the 5th perforation is 2-3cm, and in the present embodiment, the radius of the 5th perforation is 2.5cm;
Offer the 4th perforation bottom 3rd rail cover 11, the radius of the 4th perforation is 2-3.5cm, and the radius of described 4th perforation is 3cm; Be provided with bottom bar 23 in 3rd rail cover 11, bottom bar 23 be provided with the second external screw thread 200, bottom bar 23 is connected with the second connecting rod 101 through the 3rd perforation 112, and the lower end of bottom bar 23 passes the 4th perforation, and is fixed by nut.
It can be the 3rd perforation 112 that gap state connects for head rod 22 end that clamping ring 3 mainly has with the first rail cover 11 setting location-plate 111, drive link 21 is provided with locating piece 41 and storage tank 42 with the corresponding end face of head rod 22, and restriction locating piece 41 axial displacement cover plate 43, when this cover plate 43 has restriction radial rotating angle design, locating piece 41 just has the power of fastening when relatively rotating with storage tank 42, make drive link 21 transmission head rod 22 smoothly, the degree of depth of storage tank 42 is greater than the thickness of locating piece 41, thus storage tank 42 can provide the space of locating piece 41 axial displacement further.
Therefore, the configurable travelling gear 211 of drive link 21 and driving by the driving gear 51 on motor 5, head rod 22 can produce screw thread along with the drive of drive link 21 with bottom bar 23 and formed thus form lift adjustment, there is between drive link 21 and head rod 22 locating piece 41 and the drive link 21 of angle-limiting structure function, when drive link 21 and bottom bar 23 cause error less than locating on the same line, can by the left and right displacement of head rod 22, tilted upward function automatically to the driving force of drive link 21 extremely bottom bar 23 resistance and offset, because locating piece 41 and drive link 21 are in rotatable state, make head rod 22 in rotatable state, therefore can move left and right, wear plate is coated with at the contact surface up and down of locating piece 41, increase the service life, thus the object of smooth operation elevating bracket 10 can be reached, in the present embodiment, the helicitic texture of three rail covers and elevating lever 2 thereof can be applied, by bottom bar 23 and head rod 22 thereof, all there is the same pitch, it is hereby ensured that the elevating bracket 10 of same table both sides all has the object of synchronous height.
More than describe preferred embodiment of the present invention in detail.Should be appreciated that those of ordinary skill in the art just design according to the present invention can make many modifications and variations without the need to creative work.Therefore, all technical staff in the art, all should by the determined protection domain of claims under this invention's idea on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment.
