Abstract
The utility model discloses an adjustable support for a chair. The adjustable support for the chair comprises a top cap (1); and eight installing holes (3) are formed on each of two opposite installing sides (2) of the top cap (1). By adopting the structure that the number of the installing holes (3) on each of the two installing sides (2) of the top cap (1) is increased to eight, namely the adjustable support for the chair is connected with the chair by more bolt tightening components, and compared with the prior art, the adjustable support for the chair has the advantages that the mechanical strength is improved twice, the intensity of the stressed instantaneous impact is higher, and the reliability is high.
Description
Technical field
The utility model relates to the vehicular spare parts field, specifically is a kind of seat adjustable support that is used for engineering trucks such as excavating machine.
Background technology
The seat adjustable support that is used for engineering truck at present generally is to adopt top cover to be connected with chair configuration; On two relative installation limits of top cover four bolt mounting holes are set respectively; Be that whole seat adjustable support adopts eight bolt fasteners to be connected with chair, and engineering truck generally all can have high-intensity vibrations in operation, can produce stronger instantaneous impact this moment; Present this connection structure mechanical strength is low, and reliability is low.
The utility model content
The technical matters that the utility model will solve is, overcomes the defective of above prior art, and the seat adjustable support that a kind of mechanical strength is high, reliability is high is provided.
The technical scheme of the utility model is, a kind of seat adjustable support is provided, and it comprises top cover, respectively is provided with eight mounting holes on two relative installation limits of said top cover.
After adopting above structure, the utility model compared with prior art has the following advantages:
The utility model seat adjustable support is increased to eight mounting holes in each limit on two installation limits of top cover; Be that the seat adjustable support adopts more bolt fastener to be connected with seat; Mechanical strength has improved 2 times on original basis; It is better to bear the temporary impact intensity of force, and reliability is high.
As improvement, the midway location on said each installation limit also respectively is provided with a knock hole.Adopt this structure, when the assembling of seat adjustable support and seat, can adopt knock hole to position, convenient for assembly, and each installs limit and has and increased a connecting bore, and mechanical strength is higher.
As improvement, the upper surface of said top cover is provided with reinforced rib.Reinforced rib is set on top cover, has improved the mechanical strength on the top cover plane, and because seat is to be assembled together with top cover; The body weight pressure of chaufeur can directly pass to reinforced rib from seat and pass on the top cover again; Thereby make the stressed more even of top cover, improved the pressure resistance of top cover, not yielding; Therefore seat also just is difficult for tilting, and has correspondingly improved the safety of chaufeur.
Said reinforced rib is two, and said two reinforced ribs are splayed and arrange.Adopt this structure, processing is simple, and intensity is higher.
Description of drawings
Accompanying drawing is the structural representation of a kind of seat adjustable support of the utility model.
As shown in the figure: 1, top cover, 2, the limit is installed, 3, mounting hole, 4, knock hole, 5, reinforced rib.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.
Shown in accompanying drawing, a kind of seat adjustable support of the utility model, it comprises top cover 1, respectively is provided with eight mounting holes 3 on two relative installation limits 2 of said top cover 1.The seat adjustable support adopts bolt fastener to be connected with seat.
The midway location on said each installation limit 2 also respectively is provided with a knock hole 4.Adopt this structure, when seat adjustable support and seat assembling, can adopt knock hole 4 to position; Convenient for assembly; And each installation limit 2 has and has increased a connecting bore, is equivalent to adopt altogether 18 bolt fasteners that seat is connected with the seat adjustable support, and mechanical strength is higher.
As improvement, the upper surface of said top cover 1 is provided with reinforced rib 5.Reinforced rib is set on top cover, has improved the mechanical strength on the top cover plane, and because seat is to be assembled together with top cover; The body weight pressure of chaufeur can directly pass to reinforced rib from seat and pass on the top cover again; Thereby make the stressed more even of top cover, improved the pressure resistance of top cover, not yielding; Therefore seat also just is difficult for tilting, and has correspondingly improved the safety of chaufeur.
Said reinforced rib 5 is two, and said two reinforced ribs 5 are splayed and arrange.Adopt this structure, processing is simple, and intensity is higher.
