Description

Combination chair pin

[technical field]

The utility model relates to a kind of pawl type chair pin of seat, particularly a kind of combination chair pin.

[background technology]

The chair pin of existing office seating mostly is pawl type chair pin greatly, the structure of pawl type chair pin comprises the hollow feet that a centre mount and several and centre mount fuse, leg evenly is laid in the centre mount periphery, use the weight of bearing seat itself and user's weight, because of these pawl type chair pin are one-time formed, the space between each leg is very big, can take many additional spaces during packing, volume after the packing is bigger, causes packing cost and cost of transportation to improve.The existing integrated structure of chair pin needs to use bigger mould during fabrication, and the chair pin of different size can only be used in certain specific chair usually, can not be general, cause the high raising of manufacturing cost.

[utility model content]

The purpose of this utility model is: overcome the deficiencies in the prior art, a kind of combination chair pin is provided, this kind chair pin can be saved packing, and can effectively reduce occupied storage space.

The technical solution of the utility model is achieved in that it comprises centre mount and leg, its improvements are: centre mount and leg are combined connecting structure, centre mount is connected with runners, runners evenly is laid in the peripheral position place of centre mount and one-body molded with centre mount radially, the external part of runners is uncovered, and the inwall symmetry of runners offers draw-in groove; One end of leg is provided with the connector that can stretch in the runners, and connector is provided with the fixture block that cooperates chucking with draw-in groove, and the end face of runners external part engages with the end face that leg is provided with connector;

In the combinations thereof chair pin, described runners bilateral symmetry offers the spill screens that extends to the runners bottom surface; Connector is a T shape structure, and the terminal tenon that forms of connector is arranged in the spill screens of runners;

In the combinations thereof chair pin, described fixture block is a wedge shaped projection;

In the combinations thereof chair pin, the uncovered width of described runners external part matches with the width of connector;

In the combinations thereof chair pin, be provided with ribs in the described runners;

In the combinations thereof chair pin, the bottom surface of described leg end is provided with the castor seat, and the castor seat is equipped with castor, and castor and castor seat are the engagement connection structure.

Than existing chair pin, the beneficial effects of the utility model are: convenient in carrying, and practicality is good, and the centre mount of chair pin and leg can be packed respectively during transportation for dividing body structure, help reducing occupied space, thereby reduce packing cost and cost of transportation; It is easy for installation, simple, is connected firmly, and need not to use extra connector; The fixedly chair pin that centre mount and runners constitute can be used as general part, and leg can be according to using needs make different length, being combined into the chair pin of different size, and can reduce manufacturing cost, helps improving the market competitiveness.

Fig. 2 is the upward view of combination chair pin

Among the figure: 1, centre mount; 11, centre bore; 2, runners; 21, cavity; 22, draw-in groove; 23, spill screens; 3, leg; 31, connector; 32, fixture block; 33, tenon; 34, castor seat; 4, ribs.

[specific embodiment]

As depicted in figs. 1 and 2, combination chair pin of the present utility model is a pawl type chair pin, it comprises centre mount 1, runners 2 and leg 3, centre mount 1 is circular pedestal, pedestal central authorities offer the centre bore 11 that is used to install seat air pressure rod, centre mount 1 and runners 2 one-body molded formation are the chair pin fixedly, before the installation, leg 3 and fixedly the chair pin for dividing a body structure.With flat five pawl chair pin is example, centre mount 1 is connected with five runners 2, five runners 2 evenly are laid in the peripheral position place of centre mount 1 radially, runners 2 is provided with downward opening cavity 21, cavity 21 is extended down to the external part of runners 2 from runners 2 the inners that are connected with centre mount 1, and is narrower than the uncovered of cavity 21 width in the external part formation of runners 2; Symmetry offers draw-in groove 22 on the inwall of runners 2 both sides, the also symmetrical spill screens 23 that offers spacing usefulness on the inwall of runners 2, and spill screens 23 extends to the bottom surface of runners 2; In the cavity 21 of runners 2, between spill screens 23 and centre mount 1, be provided with some ribs 4,, prevent runners 2 torsional deformations or fracture to strengthen the intensity of runners 2.One end of leg 3 is provided with the connector 31 that can stretch in the runners 2, the uncovered width of runners 2 external parts matches with the width of connector 31, connector 31 is a T shape structure, and the tenon 33 that connector 31 terminal T shape both sides form is arranged in the spill screens 23 of runners 2.When combination chair pin was pressed down by gravity, connector 31 was deviate from runners 2, was provided with the fixture block 32 that matches with the draw-in groove 22 of runners 2 in the bilateral symmetry of connector 31, and fixture block 32 chuckings are fixed in the draw-in groove 22.The bottom surface of leg 3 ends is provided with castor seat 34, and castor seat 34 is equipped with castor, and castor and castor seat 34 are the engagement connection structure.For making connector 31 can firmly be clamped in the runners 2, preferably, connector 31 is interference fit with runners 2 open-mouth inwalls, the spacing of bilateral symmetry fixture block 32 is greater than the spacing of runners 2 both sides inwalls, so, for the ease of installing, fixture block 32 can be made wedge shaped projection, the small end of wedge shaped projection is towards the draw-in groove 22 of runners 2.In order to solve the problem that wedge shaped projection and draw-in groove 22 are difficult to aim at, draw-in groove 22 can be designed to the rectangular chute of level, chute if guarantee with wedge shaped projection in contour position.

During installation, fixedly chair pin reversing, allow runners 2 the bottom surface up, the leg 3 that reverses simultaneously faces up one of castor seat 34, the connector 31 of leg 3 is inserted in the runners 2, two tenons 33 of connector 31 ends are sticked in the spill screens 23 of runners 2, connector 31 is knocked in the cavity 21 that embeds runners 2 by aids such as hammers subsequently, fixture block 32 until connector 31 both sides snaps in the draw-in groove 22 of runners 2 inwalls fully, makes leg 3 be provided with the end face fluid-tight engagement of the end face and runners 2 external parts of connector 31.

In this novel combination chair pin, leg 3 can be according to using needs make different length, thereby be combined into the chair pin of different size with fixing chair pin.

Described above only is preferred embodiment of the present utility model, and above-mentioned specific embodiment is not to restriction of the present utility model.In technological thought category of the present utility model, various distortion and modification can appear, and the retouching that all those of ordinary skill in the art make according to above description, revise or be equal to replacement, all belong to the scope that the utility model is protected.
