1, owing to the moulding reason, product cannot exchange, and can't realize the core institution normalisation.Therefore each project all needs redesign, makes mould again, causes cost consumption to increase, and work efficiency reduces;
2, product colour outward appearance instability.Owing to be subjected to the characteristic limitations of present materials used, under the situation of wet environment, solar light irradiation, product is easy to take place the color change, makes headrest guide pin bushing and whole chair color inconsistent, cause the probability that defective products takes place because of the color disunity a whole set of seat to increase greatly, cause huge waste;
3, because the headrest guide pin bushing is a critical component, need carry out the detection of multiple mechanical test.If develop a kind of new headrest guide pin bushing, just need do various testing experiments again, prolong the project duration easily, increase project cost.
The utility model content
The purpose of this utility model is to provide a kind of sectional type headrest guide pin bushing, make its core members become general part, under the situation of product-forming change, the block that only needs to change top just can be realized its function, various to overcome present headrest guide pin bushing structure, redesign long technical matters of cost height, design and test period.
In order to achieve the above object, the technical solution of the utility model is as follows:
A kind of sectional type headrest guide pin bushing comprises guide pin bushing main body, block and locking mechanism; Described guide pin bushing main body comprises top and the bottom column that links to each other with this upper plane; Described top is provided with first draw-in groove, second draw-in groove, punch and position-limited trough; Described block is provided with the fixture block with the clamping of described first draw-in groove coupling; Described locking mechanism includes plastic button spare, Metallic card and spring; Described spring is inserted in the punch of guide pin bushing main body; Metallic card is provided with screens button and chimb, and described screens button fastens the position-limited trough of guide pin bushing main body; The side of plastic button spare is provided with the 3rd draw-in groove, and the 3rd draw-in groove of the chimb of Metallic card and Plastic Parts button mates clamping mutually.
The bottom column of described guide pin bushing main body is provided with buckle.
Described first draw-in groove is located on the bottom surface on described guide pin bushing main body top.
Described second draw-in groove and position-limited trough are located on the side on described guide pin bushing main body top.
Described punch is located on the end face on described guide pin bushing main body top.
The utility model provides a kind of detachable headrest guide pin bushing, owing to adopted the design of detachable formula, the headrest main body can normalisation, can avoid developing cost-cutting again; The outward appearance of wherein blocking a shot is improved and can be changed according to customer requirement, only needs to change block; Block has been selected for use under the situation of wet environment, solar light irradiation, and color is difficult for the material of change, because the head that has only the headrest guide pin bushing as seen, so only need change the material of block; Because the headrest main body is the critical component of headrest guide pin bushing, need satisfy the requirement of multiple mechanical test, so the more conversion materials of main body of resting the head on because the headrest main body does not change, does not just need to do again various testing experiments.
