Description

Liftable foot device

technical field

The utility model relates to a support device, in particular to a liftable foot device.

Background technique

The anchor device is usually installed at the bottom of the equipment, and it mainly plays the role of supporting the equipment between the ground and the equipment. Generally, there are certain strength requirements for the materials used; however, the anchor device is usually at the bottom of the equipment, so it is easy to be ignored , so the existing foot devices generally only consider the quality problem, and less consideration is given to other factors, such as the problem of freely adjusting the height of the foot device: when the ground is uneven, adjust the height of each foot device To make it maintain the horizontal state of the equipment; in addition, there is a lack of consideration for the stability and the overall aesthetics of the equipment.

Contents of the invention

In order to overcome the shortcomings and deficiencies of the prior art, the utility model provides a liftable foot device, which has the advantages of convenient height adjustment, good stability, firm positioning, long service life and beautiful appearance.

The technical scheme that the utility model solves its technical problem adopts is:

The liftable anchor device includes a base and a lifting structure fixed on the base, the base is fixed to the ground through expansion bolts; the lifting structure includes a screw, a first nut, a second nut, a square tube of the base, and a screw Penetrating vertically into the square tube of the base, the first nut and the second nut are respectively arranged on the said screw located inside and outside the square tube of the base; the side wall of the square tube of the base is provided with a square hole through which the first nut can be rotated; A detachable shielding cover is installed on the outside of the square hole.

The base is prepared by steel plate.

The screw rod is fixed on the base by welding.

Further, the shielding cover is installed on the outside of the square hole through bolts.

Further, the contact surfaces of the first nut, the second nut and the square tube of the base are respectively provided with nut washers.

The beneficial effects that the utility model has are as follows:

(1) The first nut can be rotated through the square hole on the square tube of the base to adjust the height of the anchor device, and two nuts are used to fix the height of the screw rod, which is more stable and firm.

(2) In addition, the base of the anchor device is made of steel plate, which has strong corrosion resistance; the steel plate is in direct contact with the ground, which increases the contact area between the anchor device and the ground, and is fixed to the ground by expansion bolts, further increasing the connection between the equipment and the ground Stability, firm positioning.

(3) The outside of the square hole of the square tube of the base is equipped with a cover to ensure that the appearance of the anchor device is more beautiful; The cover can prevent rainwater from entering the square tube of the base, keep the inside dry and prolong the service life of the device.

(4) In addition, the utility model has a simple device, a short production time, and the product is not prone to quality defects, and has high practical value.

Among them, 1-fixing bolt, 2-shielding cover, 3-base square tube, 4-nut, 4a-first nut, 4b-second nut, 5-screw, 6-expansion bolt, 7-base, 8- Square hole.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in FIGS. 1 and 2 , the anchor device includes a fixing bolt 1 , a cover 2 , a base square tube 3 , a nut 4 , a screw rod 5 , an expansion bolt 6 , a base 7 and a square hole 8 . A square hole 8 is arranged on the square tube 3 of the base, and the outside of the square hole 8 fixes the shielding cover 2 through the fixing bolt 1, and the shielding cover 2 ensures that the appearance is beautiful and prevents foreign matter or rainwater from entering the square tube 3 of the base; the shielding cover 2 can be disassembled. When the foot device of the embodiment needs to be adjusted in height, the shielding cover 2 is then removed.

The base 7 is made of steel plate, and only part of the steel plate protrudes from the outside of the base. The steel plate and the expansion bolt 6 are fixed to the ground, and the use of the expansion bolt 6 plays a role of stable positioning; the base 7 is welded with a screw rod 5 .

Screw rod 5 penetrates in the base square tube 3, and the first nut 4a can be rotated by the square hole 8 on the base square tube 3 (on the screw rod 5 inside the base square tube 3); on the screw rod 5 outside the base square tube 3 There is a second nut 4b, and the two nuts are used to fix the height of the anchor device, which is more stable and firm: specifically, when the height of the anchor device needs to be raised, first rotate the first nut 4a to a certain height and fix it, and then lift the The heights of the high-base square tube 3 and the second nut 4b are not fixed; otherwise, the opposite is true. In a word, the two nuts on the screw rod 5 make the anchor device more stable and firm through the joint action of the upper and lower nuts, and the height can be adjusted conveniently.

Nut gaskets are provided on the contact surfaces of the first nut 4a, the second nut 4b and the base square tube 3 respectively, and the nut gaskets can reduce the wear of the first nut 4a and the second nut 4b on the contact surface of the base square tube 3 .
