Detailed description of the invention
The technical solution of the utility model is further illustrated below in conjunction with Figure of description and specific embodiment.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
The utility model provides a kind of liftable brace table, and described liftable brace table can be used for supporting ultrasonic host desktop or portable ultrasonic equipment etc.
In liftable brace table one embodiment that Fig. 1 to Fig. 5 the utility model provides, described liftable brace table 100 comprises base 1, lower pillar stand 2, upper pillar stand 3 and loading plate 4, wherein, the bottom of described base 1 is provided with rolling mechanism 10, described lower pillar stand 2 is installed on described base 1, described upper pillar stand 3 is sheathed on the periphery of described lower pillar stand 2 slidably, described loading plate 4 is installed on the upper end of described upper pillar stand 3, the sidewall of described upper pillar stand 3 is provided with the spring pin 5 in the inner chamber that can stretch to described upper pillar stand 3, the outer wall of described lower pillar stand 2 is provided with multiple upper and lower spaced knock hole 6, and in the present embodiment, specifically consult Fig. 4, the sidewall of described lower pillar stand 2 is provided with the locating plate 21 of downward-extension, described knock hole 6 is located on described locating plate 21.Free state when described spring pin 5 has compressive state when being suppressed by the outer wall of described lower pillar stand 2 and stretches to knock hole 6 and coordinate with knock hole 6.
After described spring pin 5 coordinates with one of them knock hole 6, want the lifting realizing described loading plate 4, can first described spring pin 5 outwards be extracted and be separated with this knock hole 6, now, described upper pillar stand 3 can slide with described lower pillar stand 2, when unclamping described spring pin 5, described spring pin 5 ejects and inner chamber to described upper pillar stand 3 moves, and press with the outer wall top of described lower pillar stand 2 and be also namely in compressive state, when described upper pillar stand 3 continues up or down, described spring pin 5 will be aimed at another knock hole 6, and stretch to knock hole 6 and coordinate with knock hole 6 under the effect of natural resiliency power and be namely in free state, described upper pillar stand 3 realizes being elevated with different coordinating of knock hole 6 by described spring pin 5 from described lower pillar stand 2.Adopt the structure of pure machinery to realize lifting, there will not be the problem that can not be elevated when power-off or gas leakage.
Obviously, the design is not limited thereto, in another embodiment, described upper pillar stand 3 is plugged in the inner chamber of described lower pillar stand 2 slidably, correspondingly, the sidewall of described lower pillar stand 2 is provided with the described spring pin 5 in the inner chamber that can stretch to described lower pillar stand 2, and the outer wall of described upper pillar stand 3 is provided with multiple upper and lower spaced knock hole 6, other structures are substantially the same, do not repeat at this.
Referring to Fig. 2, is free-running fit between described upper pillar stand 3 and described lower pillar stand 2, thus, easily slide between described upper pillar stand 3 and described lower pillar stand 2.
Further, the sidewall of described upper pillar stand 3 is provided with in the inner chamber that can stretch to described upper pillar stand 3 in order to compress the setting nut 8 of described lower pillar stand 2, thus, coordinate with knock hole 6 at described spring pin 5, and when making described upper pillar stand 3 and described lower pillar stand 2 stationary positioned, described lower pillar stand 2 can be compressed by described setting nut 8 and reduce the load-bearing burden of described spring pin 5.Obviously, the design is not limited thereto, and in another above-mentioned embodiment, the sidewall of described lower pillar stand 2 is located at by described setting nut 8, and described setting nut 8 can stretch in the inner chamber of described lower pillar stand 2 in order to compress described upper pillar stand 3.
Refer to Fig. 2 and Fig. 5, the outer wall of described lower pillar stand 2 is convexly equipped with protruding 7 (described in diagram, projection 7 is cylindrical), described protruding 7 have the outer face 71 abutted with the inwall of described upper pillar stand 3, to reduce the area of contact between described lower pillar stand 2 and the inwall of described upper pillar stand 3, obviously, the design is not limited thereto, in another above-mentioned embodiment, described protruding 7 outer walls being located at described upper pillar stand 3, the described outer face of protruding 7 71 abuts with the inwall of described lower pillar stand 2.Preferably, described outer face 71 is arranged in curved surface.
These are only preferred embodiment of the present utility model; not thereby its scope of the claims is limited; every utilize the utility model specification sheets and accompanying drawing content to do equivalent structure or equivalent flow process conversion; directly or indirectly be used in the technical field that other are relevant, be all in like manner included in scope of patent protection of the present utility model.
