Abstract

The utility model relates to a lifting desk and chair, which belongs to a furniture field. The leg is composed of an inner tube, an outer tube, an adjusting rod for playing the lifting and positioning action and a positioning pin, and the inner tube and the outer tube can relatively move. A plurality of positioning holes are arranged on the outer tube, and an upper end adjusting handle is arranged at the upper part of a lifting tube. The adjusting rod extends into the inner tube, and a supporting arm is arranged at the lower end of the adjusting rod. The positioning pin can be arranged at the lower end of the adjusting rod, the positioning pin and the lower end of the adjusting rod form an integrative structure, and the positioning pin is hinged with the adjusting rod in the inner tube through a shaft. A turning handle causes the positioning pin to be retracted into the inner tube from the positioning holes, and the height of the utility model can be adjusted. Then the turning handle cause the positioning pin to extend into the positioning holes, thus realizing the positioning function. The utility model has simple structure and convenient use.

Description

Height adjustable desk

The utility model belongs to field of furniture, to relating to a kind of tables and chairs with elevating function.

Tables and chairs (stool) are people's routine works, indispensable apparatus in the studying and living, and the employed fruit chair of people has still continued stationary structure for many years for the edge at present, the height of tables and chairs can't arbitrarily be adjusted, thereby used and in bring to people and to be permitted my inconvenience, especially for minor teenager, the table of its use, chair needs often to adjust height, to adapt to its body development and to guarantee to have correct sitting posture, also there is up-down desk and chair to sell in the market, solved the problem that like product can not lifting, but its lifting is to transfer up and down along column with bar, with four bolting realizations, in lifting process, need two people to operate simultaneously, and structure is very unreasonable.

The purpose of this utility model promptly produces thus, proposes a kind of reasonable in design, the elevatable desk and chair of flexible and convenient operation.

The case of the utility model by following technology realizes above-mentioned purpose, and the shank of up-down desk and chair mainly is made up of pipe, outer tube in relatively-movable and the adjusting rod and the alignment pin that are used for the lifting positioning action; A plurality of locating holes are not put on outer tube, adjusting rod upper end handle is arranged on lifting top, the adjusting rod lower end is stretched in the interior pipe, the adjusting rod lower end is the curved boom of a band alignment pin, when handle rotates adjusting rod lower end alignment pin from the inner tubal wall hole, stretch realize the location in should be to the location on the outer tube several or go back in can adjust table height in the pipe, adjusting rod lower end and alignment pin curved boom be angled a supporting arm, supporting arm rotated along inner tubal wall when adjusting rod rotated, guarantee that alignment pin is curved along the track rotation, the pin head stretches out from arm hole or withdraws.

Adjusting rod lower end alignment pin and adjusting rod also can split, being about to alignment pin is glued in the pipe with shaddock, spring stretches out in the locating hole that the inner tubal wall hole enters outer tube the pin head automatically, when needs adjustment height, the rotary regulating lever handle, adjusting rod moves to tube hub owing to abutment wall effect (moving along inner tubal wall) when rotating, move to tube hub thereby promote alignment pin, in the pipe, can adjust the desk mayor in the pin head bounces back to, back turning handle, adjusting rod is back to original position when rotating, and alignment pin also is back to original position, and the pin head is under spring action, again outside the protruded tube, the locating hole that enters on the outer tube is realized the location.

Desktop in the utility model can be ordinary desktop, also can be the tiltable certain angle with convenient reading, the multi-function desktop of mapping drawing.

Alignment pin pin head of the present utility model can be designed to upwards have the structure of certain inclination, thinks when adjusting upward the height of desk, can directly upwards mention and can adjust, and only needs the rotary regulating lever handle to carry out when adjusting height downwards.

The utility model proposes elevatable desk and chair, very convenient when adjusting height, lifting and location structure are comparatively simple, are very suitable for family and school student and use.

The utility model provides the following drawings:

Accompanying drawing 1 is the utility model same table structural representation;

Accompanying drawing 2 is the utility model embodiment 1 lifting part schematic diagram;

Accompanying drawing 3 is an adjusting rod structural representation among the embodiment 1;

Accompanying drawing 4 is the utility model embodiment 2 lifting part schematic diagrames;

Accompanying drawing 5 shows the figure that determines for adjusting rod structure among the embodiment 2;

Accompanying drawing 6 is a locating pin structure schematic diagram among the embodiment 2;

Accompanying drawing 7 is the utility model chair lift structural representation;

As shown in Figure 1, the lifting of the utility model same table part mainly is made up of interior pipe 6, outer tube 5 and the adjusting rod 12 and the locating hole 7 that are used for the lifting positioning action, pipe 6 is arranged on the bottom as standpipe wherein, pipe top can move up and down by internal mutually pipe in outer tube 5 was enclosed within, as fall way, be provided with a plurality of on the outer tube in order to be implemented in the locating hole 7 of differing heights position by alignment pin 8; Outer tube 5 is that fall way is connected with desktop 1, as is to connect with right-angle connecting plate 4, and right-angle connecting plate one right-angle side is connected on the desktop, and another right-angle side is connected on the outer tube by bolt 3.For guaranteeing the firm of desk, two holder supports 10 can be set in the bottom, the middle straight-bar (or pipe) 9 that passes through connects.

As accompanying drawing 2, structure shown in 3, it is fall way 5 tops that adjusting rod 12 handles 2 are positioned at outer tube, can in the groove of offering, rotate, the adjusting rod lower end is stretched in the pipe until interior pipe top, the adjusting rod lower end is one to have the curved boom of alignment pin 8, the lower end also has the support arm 11 of or certain angle curved with alignment pin, the relevant position has a hole that supplies rationed marketing 8 to stretch out on the interior pipe epimere wall, on outer tube 5, have a plurality of alignment pins 8 that supply and stretch into the locating hole 7 of realizing the location, rotary regulating lever 12 handles 2, the alignment pin of its lower end curves moving, alignment pin 8 stretches out from inner orifice, enter in the locating hole 7 on the outer tube, outer tube is fixed with respect to interior pipe, and table height is fixed; When needs are adjusted table height, rotary regulating lever handle 2, lower end alignment pin 8 is withdrawn from locating hole 7, can adjust the fall way height, turning handle makes alignment pin 8 enter locating hole 7 again and realizes the location, the effect of adjusting rod 12 lower end supporting arms 11 is that supporting arm 11 rotates along inner tubal wall when handle rotates, and guarantees the rotary motion trace that alignment pin stretches out and withdraws in the hole.

As accompanying

drawing
