Description

A kind of connecting base structure of folding seat

Technical field

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

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 is formed, the folding rack formed is that many poles coordinate multiple module composition, utilize folding rack to launch and coordinate the restriction of cloth cover and form the chair of stationary state, namely it possesses the two states launched with folding, but the state complying with seat when user uses is fixed, and cannot have multi-functional use as normal chair, and it folds volume comparatively greatly, preferably cannot embody the feature of light portable, easy-to-collection.

Therefore, the design people has just invented one, and to fold volume compacter, simple, light, the more portable folding seat with collection of structure, and can realize flexible rotating, and reach effect that person's multi-angle easy to use uses flexibly.Coordinate shown in Fig. 1,2, this folding seat coordinates each rod member 2 ' of seat bracket and chair foot support can form a folding seat primarily of the Connection Block 1 ' with jack 13 ', and each rod member 2 ' and the connection of Connection Block 1 ' can be realized each rod member 2 ' of folding seat and folding of Connection Block 1 ' and not loose function by elastic threads; This Connection Block 1 ' is by the upper bracket 11 ' of mutual pivot joint and undersetting 12 ', realizes with this relation forming mutual flexible rotating between chair foot support that seat bracket that upper bracket 11 ' coordinates coordinates relative to undersetting 12 '.

But, due to additional wear-resistant gasket 3 ' between the upper bracket 11 ' of mutual pivot joint and undersetting 12 ', therebetween certain gap can be there is, because the multiplex ground of folding seat is outdoor, the places such as such as sandy beach, therefore easily enter the impurity such as the grains of sand, dust in this gap, 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 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 addition, the Connection Block 1 ' of existing folding seat is metalwork, and material cost is relatively high, and its upper bracket 11 ', undersetting 12 ' and wear-resistant gasket 3 ' all needs machine-shaping respectively, therefore, processing cost is also quite higher, causes the cost of existing folding seat to remain high.

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 its structure is simple, effectively can reduce the manufacture difficulty of folding seat, and then reduces the cost of manufacture of folding seat, improves the competitiveness in market.

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

A kind of connecting base structure of folding seat, this Connection Block adopts plastic material one-body molded, this Connection Block forms the projection coordinated for each rod member of seat bracket and each rod member of chair foot support, each projection is provided with the jack planted for corresponding rod member, and the elastic threads that the jack of each projection is interconnected for each rod member of constraint wears.

Reinforcement is provided with between each projection of described Connection Block.

Necking down step is formed in each jack of described Connection Block.

After adopting such scheme, connecting base structure due to a kind of folding seat of the utility model adopts plastic material one-body molded, this Connection Block is when production and processing, only need to carry out a die sinking can complete, therefore, compared to the repeatedly processing of existing metal-connecting seat, the utility model has the advantage that structure is simple, processing cost is low, manufacturing procedure is simple, material cost is also low, effectively can reduce the manufacture difficulty of folding seat, and then reduce the cost of manufacture of folding seat, improve the competitiveness in market.

In addition, in each jack of Connection Block, necking down step is arranged, 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 need to carrying out the processing of necking down to each rod member, make the making of whole folding seat more simplify, effectively reduce cost of manufacture.

Detailed description of the invention

In order to explain the technical solution of the utility model further, below by specific embodiment, the utility model is elaborated.

As shown in Figure 3, Figure 4, the utility model discloses a kind of connecting base structure of folding seat, this folding seat is the Connection Block 3 comprising seat bracket 1, chair foot support 2 and be flexibly connected seat bracket 1 and chair foot support 2, seat bracket 1 is linked together by elastic threads and Connection Block 3 with each rod member of chair foot support 2, and seat bracket 1 is combined with seat support cloth cover (not shown).

Connection Block 3 adopts plastic material one-body molded, this Connection Block 3 forms the multiple projections 31 coordinated for each rod member of seat bracket 1 and each rod member of chair foot support 2, each projection 31 is provided with the jack 32 planted for corresponding rod member, the jack 32 of each projection is interconnected, elastic threads 4 for each rod member of constraint wears, need carry out a die sinking when this Connection Block 3 is produced, and between each projection 31, form reinforcement 33 when die sinking, the setting of reinforcement 33 can strengthen the bulk strength of this Connection Block 3.

The utility model Connection Block 3 can form necking down step 34 and just lean on this necking down step 34 for corresponding Rod end in each jack 32, realizes firm location.Certainly, also can form necking down at seat bracket 1 with each Rod end of chair foot support 2 to be directly inserted in each jack 32.

The connecting base structure of a kind of folding seat of the utility model adopts plastic material one-body molded, this Connection Block 3 is when production and processing, only need to carry out a die sinking can complete, therefore, compared to the repeatedly processing of existing metal-connecting seat, the utility model has the advantage that structure is simple, processing cost is low, manufacturing procedure is simple, material cost is also low, effectively can reduce the manufacture difficulty of folding seat, and then reduce the cost of manufacture of folding seat, improve the competitiveness in market.

In addition, the setting of necking down step 34 in each jack 32 of Connection Block 3, the end of each rod member of seat bracket and chair foot support is made just to lean on this necking down step 34, realize firm location, without the need to carrying out the processing of necking down to each rod member, make the making of whole folding seat more simplify, effectively reduce cost of manufacture.

Above-described embodiment and graphic and non-limiting product form of the present utility model and style, any person of an ordinary skill in the technical field, to its suitable change done or modification, all should be considered as not departing from patent category of the present utility model.
