Abstract

The utility model relates to an anti-electrostatic movable trestle for floors, comprising an upper support, a regulating nut, a locknut, an upright post, a base, positioning tenons, a sleeve and triangular ribs. The upper support is a cross-shaped thin slab, and the four positioning tenons are fixed on the top surface of the upper support. The sleeve which is arranged below the upper support is welded with the upper support, and the four triangular ribs are welded on the periphery of the sleeve. The sleeve which is sheathed on the upper end of the upright post is glidingly connected with the upright post, and the regulating nut which is arranged below the sleeve is matched with the threads of the upright post. The utility model has the advantages of simple structure and convenient construction. When the height of the trestle is regulated, the trestle is unnecessary to be jacked, and the upper support can be jacked or lowered only by turning the regulating nut. The utility model is applicable as a supporting member for anti-electrostatic movable floors in computer rooms.

Description

Anti-electrostatic telescopic trestle for floor

The utility model relates to a kind of antistatic raised floor support, belongs to the member class that the building fitting-out work is used.

Chinese patent CN2049852U discloses a kind of " woven movable floor rack ", comprises pop-up, nut, strut bar, base, and pop-up is the square tube part, is connected with the crossbeam of screw with both sides and centre.The weak point of this device is that structure is complicated, and when adjusting support height, must come rotating base to regulate by the jack-up support, is not easy to installation.

It is a kind of simple in structure that the purpose of this utility model is to provide, and the antistatic raised floor support of easy construction can be used as the load-carrying element of the antistatic raised floor of computer room.

The purpose of this utility model reaches as follows: a kind of antistatic raised floor support comprises pop-up, setting nut, jam nut, column, base.Pop-up is the criss-cross thin plate, fixedly establishes 4 location lugs on the pop-up end face, and 4 location lugs are pressed right-angled crossing and distributed.When antistatic raised floor was installed, a rectangle knock hole was respectively opened at the crossbeam two ends, as long as knock hole is enclosed within on the location lug of above-mentioned movable floor rack, it is very convenient to construct.Below pop-up, establish a sleeve,, play a supportive role with the pop-up solder together.The column upper end is provided with external screw thread and installs setting nut and jam nut, and sleeve is contained in the setting nut top and is enclosed within the upper end of column, with the column sliding block joint.When adjusting support height, need only rotate setting nut earlier, with sleeve and on jack up or fall, get final product with jam nut locking again, it is simple and convenient to construct.

The purpose of this utility model can also following mode reach: column and base solder together.Base can be made the exit skirt shape, improving support stability, and has correspondingly reduced the requirement to ground flat degree.

Can establish 4 triangle muscle in the pop-up bottom, with triangle muscle and pop-up, sleeve solder together all, to improve the structural strength of support.

The utility model comparison prior art has following advantage:

1. sleeve and column sliding block joint when adjusting support height, needn't come rotating base by the jack-up support, and setting nut that need only the turnbarrel below is for construction and installation are provided convenience.

2. simple in structure, easy to manufacture, cost is low.

The drawing of accompanying drawing is described as follows:

Fig. 1 is the block diagram of a kind of embodiment of the present utility model.

Fig. 2 is the structure cutaway view of the foregoing description.

The utility model will be further described as follows in conjunction with the accompanying drawings:

See figures.1.and.2.A kind of antistatic raised floor support, comprise pop-up (1), setting nut (2), jam nut (3), column (4), base (5), 4 location lugs (6), sleeve (7), triangle muscle (8), pop-up (1) is the criss-cross sheet steel, 4 location lugs (6) are pressed square crossing and are distributed, and are fixed on the end face of pop-up (1).Sleeve (7) is in pop-up (1) below, and 4 triangle muscle (8) at the following square socket (7) of pop-up (1) all around.Pop-up (1), sleeve (7) and triangle muscle (8) be solder together all.Sleeve (7) is enclosed within column (4) upper end, and column (4) upper end has external screw thread, setting nut (2) to be contained in sleeve (7) below and column (4) screw thread fit, and lock nut (3) is the side under setting nut (2).Column (4) and base (5) solder together, base (5) is a toroidal.
