Abstract
The utility model relates to office furniture, in particular to a desk and chair lifting frame used for regulating the height of a desk and a chair. The desk and chair lifting frame comprises a first pipe body and a second pipe body, wherein the first pipe body comprises an upper pipe pin, and the upper pipe pin can be inserted into a hollow lower pipe pin of the second pipe body. The desk and chair lifting frame is characterized in that the tail part of the pipe pin is provided with two pressing riveting screw nuts with threaded holes, different height positions of the lower pipe pin are provided with holes with equal spaces, and the spaces of the holes are equal to the distance between the two pressing riveting screw nuts. The desk and chair lifting frame has the advantages that the lifting function of the desk and the chair can be effectively realized, in addition, the structure is simple, and the cost is low.
Description
Technical field
The utility model relates to a kind of office furniture, particularly relates to the tables and chairs crane that is used to regulate the tables and chairs height.
Background technology
The tables and chairs of traditional fixedly monoblock type moulding can't be fit to it with the required adjustment of different users and use height, especially can cause sitting posture bad to the adolescent student tables and chairs height discomfort of growing up, and constantly changing the differing heights tables and chairs increases use cost again.
In the adjustment action for the tables and chairs height, up-down is to realize through stretching of table pin length.In the conventional art, this crane comprises two joints hollow iron pipe or steel pipe with holes, between two pipes, add some servicing units and realize a pin telescopic, but these mechanism structure is complicated, cost is higher.
The utility model content
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is following:
The said tables and chairs crane of the utility model; Comprise first body, second body; Said first body comprises pin, said going up in the following pin of hollow that pin can insert said second body, and it is characterized in that: the said pin afterbody of going up is provided with two self-clinching nuts that are threaded the hole; The differing heights position of following pin is provided with equally spaced hole, and the spacing in said hole equates with distance between two self-clinching nuts.Two groups of screw elements fixedly make support more stable.
Preferably the head of self-clinching nut protrudes from the pin, has certain clearance because the interval of head makes between pin and the following pin, solved effectively in lifting process on pin and following pin stay the problem of scratch because of the large tracts of land friction.
The utility model can be realized the elevating function of tables and chairs effectively, and simple in structure, and cost is low.
Through following description and combine accompanying drawing, it is more clear that the utility model will become, and these accompanying drawings are used to explain the embodiment of the utility model.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the left cutaway view under the utility model disassembled state.
The specific embodiment
To combine accompanying drawing that the utility model is done to specify further below, but not constitute any restriction to the utility model, the similar elements label is represented similar elements in the accompanying drawing.
As depicted in figs. 1 and 2; The said tables and chairs crane of the utility model comprises first body 1, second body 2, and said first body 1 comprises pin one 1; Said going up in the following pin two 1 of hollow that pin one 1 can insert said second body 2; Said pin one 1 afterbody of going up is provided with two self-clinching nuts 12 that are threaded the hole, and the differing heights position of following pin two 1 is provided with equally spaced hole 22, and the spacing in said hole 22 equates with distance between two self-clinching nuts 12.
The head 121 of self-clinching nut 12 protrudes from the pin one 1.
Last pin one 1 inserts the different hole 22 of pin two 1 selection down to obtain needed height, and the axis of self-clinching nut 12 with the hole of selecting 22 is located on the same line.Then screw 3 passes down the hole 22 on the pin two 1 and is connected on the self-clinching nut 12, connects to accomplish.If select different height, can unclamp screw 3, select different holes 22, accomplish to connect getting final product again again.
Claims (2)
1. tables and chairs crane; Comprise first body (1), second body (2); Said first body (1) comprises pin (11), said going up in the following pin (21) of hollow that pin (11) can insert said second body (2), and it is characterized in that: said pin (11) afterbody of going up is provided with two self-clinching nuts (12) that are threaded the hole; The differing heights position of following pin (21) is provided with equally spaced hole (22), and the spacing of said hole (22) equates with distance between two self-clinching nuts (12).
