Description

The connecting base structure of folding seat

Technical field

The utility model is about a kind of folding seat, refers to especially a kind of connecting base structure of folding seat.

Background technology

Folding seat has Foldable and portable feature, and it is not only applicable to the use in open air and interim place, is also the Emergency use article of household indispensability.Mostly traditional folding seat is that supporting cloth cover by folding rack forms, the folding rack forming is that many poles coordinate multiple module compositions, utilize folding rack to launch and coordinate the restriction of cloth cover and form the chair of stationary state, be that it possesses the two states that launches and fold, the state of complying with seat when but user uses is fixed, and cannot as normal chair, there is multi-functional use, and its to fold volume larger, cannot preferably embody the feature of light portable, easy-to-collection.

Therefore, the design people has just invented one, and to fold volume compacter, simple in structure, light, more portable and the folding seat of collection, and can realize flexible rotating, and reach effect that person's multi-angle easy to use is used flexibly.Coordinate shown in Fig. 1,2, this folding seat mainly coordinates each rod member 2 ' of seat bracket and chair foot support can form a folding seat by the Connection Block 1 ' with jack 13 ', and will can realize each rod member 2 ' and being connected of Connection Block 1 ' the each rod member 2 ' of folding seat with folding of Connection Block 1 ' and not loose function by elastic threads; This Connection Block 1 ' is the upper bracket 11 ' and undersetting 12 ' by mutual pivot joint, forms the relation of mutual flexible rotating with this between the chair foot support that the relative undersetting 12 ' of seat bracket of realizing upper bracket 11 ' cooperation coordinates.But, mutually between the upper bracket 11 ' of pivot joint and undersetting 12 ' due to additional wear-resistant gasket 3 ', between the two, can there is certain gap, because the multiplex ground of folding seat is outdoor, the places such as such as sandy beach, therefore in this gap, easily enter the impurity such as the grains of sand, dust, so just can affect the rotating function of chair, and then affect the service life of chair.In addition, when each rod member 2 ' coordinates with each jack 13 ' of Connection Block 1 ', be to form necking down step 21 ' in the end of each rod member 2 ', locate firm effect to reach with Connection Block 1 ', and also can increase the cost of manufacture of production to the necking down 21 ' processing of each rod member 2 '.

In view of this, this folding seat still has not attain improves part, haves much room for improvement.

Utility model content

The purpose of this utility model is to provide a kind of connecting base structure of folding seat, and it can effectively improve the stability of folding seat use function, to ensure the service life of product.

Secondary objective of the present utility model is to provide a kind of connecting base structure of folding seat, and it can effectively reduce the manufacture difficulty of folding seat, and then reduces the cost of manufacture of folding seat.

For achieving the above object, solution of the present utility model is:

A connecting base structure for folding seat, establishes respectively the jack for the each rod member of seat bracket and the each rod member plant of chair foot support on this Connection Block, this Connection Block comprises the articulated part of upper bracket, undersetting and pivot joint upper bracket and undersetting; Between upper bracket and undersetting, be provided with wear-resistant gasket; Wherein: form convex annular wall or form convex annular wall at undersetting upper surface periphery at the upper bracket lower surface periphery of Connection Block, the height of this convex annular wall is identical with the thickness of wear-resistant gasket, and the external diameter of wear-resistant gasket is less than the internal diameter of convex annular wall.

In each jack of described Connection Block, form necking down step.

In described upper bracket, be formed centrally axial pivoted hole, in undersetting, be formed centrally axial pivoted hole, articulated part through the pivoted hole of pivoted hole, the sheet of resistance to seat cushion and the undersetting of upper bracket so that upper bracket and undersetting are articulated.

Described articulated part is directly molded on undersetting or upper bracket, is formed centrally cooperation pivoted hole in corresponding upper bracket or undersetting.

Adopt after such scheme, because the utility model forms convex annular wall or forms convex annular wall at undersetting upper surface periphery at Connection Block upper bracket lower surface periphery, this convex annular wall just forms the protecting wall of wear-resistant gasket periphery, make upper bracket form and preferably coordinate with the outer rim of undersetting, avoid producing gap, to prevent entering of extraneous dust, ensure that Connection Block uses the stability of function, to ensure the service life of product.

In addition, in the each jack of Connection Block, necking down step arranges, and makes the end of each rod member of seat bracket and chair foot support just lean on this necking down step, realize firm location, without the processing of each rod member being carried out to necking down, make the making of whole folding seat more simplify, effectively reduce cost of manufacture.

Detailed description of the invention

Explain embodiment of the present utility model below in conjunction with accompanying drawing:

As shown in Figure 1, 2, the utility model has disclosed a kind of connecting base structure of folding seat, this folding seat is the Connection Block 3 that comprises seat bracket 1, chair foot support 2 and be flexibly connected seat bracket 1 and chair foot support 2, on Connection Block 3, establish respectively the jack for the each rod member of seat bracket 1 and the each rod member plant of chair foot support 2, seat bracket 1 links together by elastic threads 4 and Connection Block 3 with each rod member of chair foot support 2, and is combined with seat support cloth cover on seat bracket 1.

Connection Block 3 wherein comprises the articulated part 33 of upper bracket 31, undersetting 32 and pivot joint upper bracket 31 and undersetting 32; The periphery of the nearly top of this upper bracket 31 is the downward inside oblique jack 311 of radial formation and plants and coordinate for each rod member of seat bracket 1; In this upper bracket 31, be formed centrally axial pivoted hole 312; The periphery of the nearly below of this undersetting 32 is upwards inside oblique jack 321 of radial formation, is formed centrally axial pivoted hole 322 in undersetting 32; Articulated part 33 through the pivoted hole 322 of the pivoted hole 312 of upper bracket 31, undersetting 32 so that upper bracket 31 and undersetting 32 are articulated, so make the rotation relation of formation activity between upper bracket 31 and undersetting 32, between upper bracket 31 and undersetting 32, be provided with wear-resistant gasket 34 simultaneously.

Certainly, articulated part 33 can be directly molded on undersetting 32 or upper bracket 32, coordinates pivoted hole and only need be formed centrally in corresponding upper bracket 31 or undersetting 32.

Key of the present utility model is: form convex annular wall or form convex annular wall 323 at undersetting 32 upper surface peripheries at the upper bracket 31 lower surface peripheries of Connection Block 3, the height of this convex annular wall 323 is identical with the thickness of wear-resistant gasket 34, and the external diameter of wear-resistant gasket 34 is less than the internal diameter of convex annular wall 323.So in the time that upper bracket 31 coordinates with undersetting 32, this convex annular wall 323 just forms the protecting wall of wear-resistant gasket 34 peripheries, make upper bracket 31 form and preferably coordinate with the outer rim of undersetting 32, avoid producing gap, to prevent entering of extraneous dust, ensure that Connection Block 3 uses the stability of function, to ensure the service life of product.

In addition, in each jack 311 of upper bracket 31 and in each jack 321 of undersetting 32, form necking down step 313, so make seat bracket 1 and the end of each rod member of chair foot support 2 just lean on this necking down step 313, realize firm location, without the processing of each rod member being carried out to necking down, therefore make the making of whole folding seat more simplify, effectively reduce cost of manufacture.
