Abstract

The utility model discloses an improved design of a lifting table. The lifting table comprises a tabletop, a base and a supporting column, and is characterized in that the supporting column comprises an upper supporting column and a lower supporting column, the upper supporting column and the lower supporting column slide relatively, an inner chamber is arranged inside the upper supporting column, the inner chamber is connected with a slim tube, and the slim tube is communicated with air and provided with a switch. The utility model makes use of differential air pressure between the inner chamber of the upper supporting column and the external world to support the tabletop and the upper supporting column, whether the inner chamber is closed or communicated with the air can be controlled through a switch, thereby ensuring the relative sliding between the upper supporting column and the lower supporting column and enabling the tabletop to move up and down. The utility model has scientific and reasonable structural design, convenient use and safety.

Description

A kind of same table

Technical field

The utility model relates to a kind of dining table, particularly be a kind of liftable table as tea table, dining table class.

Background technology

Along with the raising of people's living standard, people are also more and more higher to the requirement of dining table, chair.Because people's height inequality, particularly adult and the height differences between the child, when using same tables and chairs, just the chair that needs height not wait is used.Look into Chinese patent database, wherein the patent No. is 200710036443.6, the patent of invention that name is called " a kind of novel height-adjustable table " discloses following content: " a kind of novel height-adjustable table; comprising: desktop, table frame, turning knob, fixed knob and universal moving runner; it is characterized in that: described table frame is made up of interior column jecket and outer column jecket; interior column jecket be provided with one section with its elevating lever of fixing, outer column jecket is provided with turning knob and fixed knob, and universal moving runner is installed below the outer column jecket.Though this kind same table has solved the problems referred to above, but liftable inside and outside column jecket adopts knob fixedly connected, need artificial rotary switch button in use, to move on column jecket in promoting and the desktop, so not only use very inconvenience, and very require great effort, particularly concerning child, the weight of desktop and interior column jecket is big, only depends on hand-power to be difficult to finish, and fixed knob revolves when tight, desktop and interior column jecket will descend rapidly, not only can frighten the user, and can break the thing on the desktop, also may bump to the user, very dangerous.

Summary of the invention

In view of the existing technical problem of background technology, technical problem to be solved in the utility model provides a kind of same table easy to use, safe.

In order to solve the problems of the technologies described above, the utility model adopts following scheme to realize: this kind same table, include desktop, base and support column, it is characterized in that described support column is divided into upper support post and lower support post, and slide relatively between upper support post and the lower support post, be provided with an inner chamber in the described upper support post, described inner chamber is connected with a tubule, this tubule communicates with atmosphere, and is provided with switch.

Described switch connects a shift knob, and this shift knob is installed on the base.

The utility model utilizes upper support post inner chamber and extraneous draught head to come supporting desktop and upper support post, by switch control inner chamber with the atmosphere closure or communicate, thereby make relative slip between upper support post and the lower support post.When desktop rises, open switch, tubule is communicated with ambient atmosphere, user's lifting desktop is closed switch to proper height; When desktop need descend, as long as open switch, desktop was slowly moving down until closing switch under external force and self gravitation effect.Shift knob is arranged on base, and only using foot is stepped on regard to controllable switch during use, and the user that is more convenient for uses.The utility model scientific structure design, reasonable, not only easy to use, quick, and fool proof, no matter be that adult, child can both use freely.

Description of drawings

Further describe relevant details and the operation principle thereof of embodiment below in conjunction with accompanying drawing.

Fig. 1 is an overall structure schematic diagram of the present utility model.

The specific embodiment

With reference to accompanying drawing, in the present embodiment, this kind same table, include desktop 1, base 9 and support column, described support column is divided into upper support post 2 and lower support post 5, and described upper support post 2 is placed in outside the lower support post 5, and can slide relatively between the two, described upper support post 2 is connected with desktop 1, is provided with an inner chamber 3 in the described upper support post 2, and described inner chamber 3 is connected with a tubule 4, this tubule 4 communicates with atmosphere, and be provided with switch 6, when closing switch 6, tubule 4 and upper support post inner chamber 3 are in closed state.6 pairs on described switch should have shift knob 8, and described shift knob 8 is installed on the base 9, and described shift knob 8 is connected with a fork 7, and the other end of described fork 7 contacts with switch 6.

When the user needs lower desktop 1, available pin slams shift knob 8, fork 7 swings is caused on the switch 6 move, and upper support post inner chamber 3, tubule 4 communicate with ambient atmosphere at this moment, because tubule is thinner, its opening is little, and the relative flowing velocity of gas is slow, so desktop can't descend fast, this moment, the user can gently press desktop 1, desktop 1 slowly moves down in the effect of external force and self gravitation, just uses relatively safety like this, to desktop and also not damage of support column; When the user decontroled shift knob 8, fork 7 set back, and switch 6 moves down, and tubule 4 is closed, and isolated with ambient atmosphere, and this moment, upper support post inner chamber 3 all was in closed state with tubule 4, and desktop 1 stops to move, and remains static.When the user needed higher desktop, the same shift knob 8 that slams adopted external force to raise desktop 1, decontroled shift knob 8 when required height, and switch 6 closures just can.

Claims

1. same table, include desktop (1), base (9) and support column, it is characterized in that described support column is divided into upper support post (2) and lower support post (5), and slide relatively between upper support post (2) and the lower support post (5), be provided with an inner chamber (3) in the described upper support post (2), described inner chamber (3) is connected with a tubule (4), and this tubule (4) communicates with atmosphere, and is provided with switch (6).

2. same table according to claim 1 is characterized in that described switch (6) to a shift knob (8) should be arranged, and this shift knob (8) is installed on the base (9).
