Abstract

The utility model discloses a desk leg with adjustable height. The desk leg comprises a tubular foot, the lower end of the tubular foot is sleeved with a pipe fitting, a mounting hole is formed in the center of the pipe fitting, and is integrated with the pipe fitting into a whole, and the end face of the mounting hole is flush with the upper end face of the pipe fitting. A screw member with a slender waist is included, the stem diameter of the polished stem of the screw member is equivalent to the hole diameter of the mounting hole, the polished stem of the screw rod is inserted into the mounting hole of the pipe fitting, a screw cap is fixedly connected with the end part of the polished stem, a transverse long opening is formed on the pipe wall of the lower end of the pipe fitting, the screw cap faces to the long opening, a screw hole is formed in the center of the tubular foot, and is integrated with the tubular foot into a whole, and the threaded rod of the screw member is screwed in the screw hole in a threaded fit manner. When the height of the desk leg is adjusted, the screw member is rotated out of or into the screw hole of the tubular foot, so that the depth of the tubular foot sleeved in the pipe fitting can be adjusted, and the adjustment of the height of the whole desk leg is realized. As the screw member used for adjusting the height of the desk leg is designed to be concealed, the appearance of the whole desk is enabled to be more beautiful, and the market competitive power is stronger compared with desks with the adjusting screw members exposed.

Description

Adjustable for height table pin

Technical field

The utility model relates to the furniture technical field.

Background technology

Desk is a kind of as furniture, and Qi Sijiao mostly is equipped with the table pin that is used for supporting, because the error in the processing or the out-of-flatness on ground make and rock easily when desk is put.The table pin is designed to adjustable height effectively addresses this problem, existing mostly is to install at the end of table pin to regulate bolt, because this adjusting bolt exposes, has directly had influence on the outward appearance of desk, makes the competitiveness of desk on market have a greatly reduced quality.

The utility model content

Technical problem to be solved in the utility model provides a kind of concealed table pin of regulating height.

Technical problem to be solved in the utility model is to realize by following technical scheme: a kind of adjustable for height table pin, include pin, lower end suit one pipe fitting of described pin, be formed centrally in the described pipe fitting and this pipe fitting all-in-one-piece, end face and the concordant installing hole in described pipe fitting upper surface, if the eel-like figure screw rod that the bar of polished rod footpath is suitable with the aperture of described installing hole, the polished rod of this screw rod is inserted on the installing hole of described pipe fitting, the fixedly connected nut in the end of described polished rod, establish a horizontal elongated opening on the tube wall of described pipe fitting lower end, described nut faces described elongated opening, be formed centrally in the described pin and this pin all-in-one-piece screw, described screw flight bar and described screw threaded engagement are installed.When regulating the height of table pin, the described screw rod of turn makes the screw of screw rod whiz or the described pin of rotation direction, the degree of depth that so just can regulate described pin and described pipe fitting suit, realize the adjusting of whole table pin height with this, and described screw rod is concealed installation.

On the basis of the above, described pipe fitting upper surface cushion cross section be slightly larger than described pipe fitting, can be sleeved on the hard plastic pad in the described pin, be formed centrally the suitable through hole in bar footpath of an aperture and described polished rod in the described plastic pad, cushion the suitable packing ring in bar footpath of aperture and described polished rod on the described through hole, be set with the plastic tube that can overlap the mouth of pipe of putting into described pin on the periphery wall of described pipe fitting.Purpose is that the pipe fitting of suit and pin are isolated, and prevents from when regulating height to abrade owing to CONTACT WITH FRICTION their surface-treated layer, can also make their tight suits and can not swing.

On the basis of the above, be formed with the groove circle on the periphery wall of described plastic pad, ring cushion rubber on the described groove circle.Purpose is to utilize the elasticity of cushion rubber, makes more closely suit of described pin and pipe fitting.

On the basis of the above, the bottom of described pin is equipped with the plastic cement foot pad, is stamped a capping on the elongated opening of described pipe fitting.

Adopt the beneficial effect that the utility model brought: owing to a screw rod of regulating table pin height is set as concealed, make the overall appearance of desk have more sight, those are regulated the desk that bolts expose and have more the market competitiveness relatively.

Description of drawings

Fig. 1 is the overall schematic of the adjustable for height table of the utility model underfooting end.

Fig. 2 is the STRUCTURE DECOMPOSITION schematic diagram (wherein pin is perspective) of the adjustable for height table of the utility model underfooting end;

The specific embodiment

As shown in Figure 1, 2, a kind of adjustable for height table pin includes pin one, lower end suit one pipe fitting 2 of pin one.Be formed centrally in the pipe fitting 2 and this pipe fitting 2 all-in-one-pieces, the end face installing hole 201 concordant with pipe fitting 2 upper surfaces.If the eel-like figure screw rod 3 that the bar of a polished rod 301 footpath is suitable with the aperture of installing hole 201, pipe fitting 2 upper surfaces cushion cross section be slightly larger than pipe fitting 2, can be sleeved on the hard plastic pad 4 in the pin one, be formed centrally the suitable through hole 401 in bar footpath of an aperture and polished rod 301 in the plastic pad 4, cushion the suitable packing ring 5 in bar footpath of aperture and polished rod 301 on the through hole 401, the polished rod 301 of this screw rod 3 is inserted on the installing hole 201 of packing ring 5, plastic pad 4 and pipe fitting 2 successively.The fixedly connected nut 6 in the end of polished rod 301 is established a horizontal elongated opening 202 on the tube wall of pipe fitting 2 lower ends, nut 6 faces elongated opening 202.Be formed centrally in the pin one and this pin one all-in-one-piece screw 101, the threaded rod 302 of screw rod 3 is installed with screw 101 threaded engagement.Plastic tube 7 is sleeved on the periphery wall of pipe fitting 2, packs into then in the mouth of pipe of pin one.Be formed with groove circle 402 on the periphery wall of plastic pad 4, ring cushion rubber 8 on the groove circle 402.The bottom of pin one is equipped with plastic cement foot pad 9, is stamped a capping 10 on the elongated opening 202 of pipe fitting 2.

When regulating the height of table pin, put in from the elongated opening of pipe fitting 2 with spanner and to block nut 6, pull spanner turn screw rod 3 then, make the screw 101 of screw rod 3 whizs or rotation direction pin one, regulate the degree of depth of pin one and pipe fitting 2 suits, promptly regulate the height of whole table pin, at last capping 10 is covered tightly on elongated opening.
