Description

The office chair runners

The utility model relates to a kind of office chair runners, refers in particular to a kind of movable disassembly and assembly to break the whole up into parts, and uses the office chair runners of saving packaging material and manufacturing cost.

General now existing common office chair, the five claw-like runners overwhelming majority of its under-seat are all made by one-body molded, seem huge and heavy, not only very inconvenience on carrying and packing, more take many additional spaces, caused the raising of packing cost and shipment and delivery cost; In addition,, therefore, when moulding, just must open the mould of enough sizes, so just cause the raising of manufacturing cost because it is one-body molded making, economical inadequately.

One of the purpose of this utility model is to provide a kind of office chair runners of movable disassembly and assembly, and it has the function that significantly reduces mould and manufacturing, packing cost.

Two of the purpose of this utility model, be to provide a kind of office chair runners with product competitiveness, the mode of assembling voluntarily after buying with the consumer can make the producer save the program of assembling, so the assembly cost that saves can be knocked down price, reach the purpose that improves product competitiveness.

The purpose of this utility model realizes by following technological means: a kind of office chair runners, form by an adapter sleeve, several chair pin and a bonding pad, adapter sleeve central authorities are the sleeve of a hollow, chair pin end is installed with an action roller free to rotate, it is characterized in that: suitably form several arc protuberances around the chair column sleeve tube of adapter sleeve, the bottom side centre of each arc protuberance then is installed with several screw hole columns; The chair pin can correspondence be arranged in each arc protuberance of connector, and its head end is preset with trepanning corresponding to the position of above-mentioned screw hole column.Can be inserted in one that have the mesopore that is inserted in for the cover barrel bottom section and be provided with the corresponding perforation of screw hole column and wear the bonding pad that combines for retaining element again in the sleeve bottom of described office chair seat support.

Advantage of the present utility model is:

1, the design that the runners of the utility model office chair can free disassembly and assembly can effectively reduce volume, has convenient carrying, and saves packaging volume, does not take advantages such as storage space.

2, the runners of the utility model office chair separates the design that moulding is made with chair pin and adapter sleeve, can significantly reduce the cost of manufacture of mould, and then save huge mould development and manufacturing expense, meets economic purpose.

3, the runners of the utility model office chair can increase the carrying capacity of means of transport relatively owing to the reduction of volume and packaging material, and then reduces cost of transportation.

4, the runners of the utility model office chair is the structure of movable dismounting, assembles voluntarily after the consumer buys and finishes, and can make the producer save the program of assembling, and the assembly cost that will save reduces the price of product, reaches the purpose that improves product competitiveness.

Describe structure of the present utility model in detail below in conjunction with accompanying drawing:

Fig. 2 is a three-dimensional exploded view of the present utility model

Fig. 3 is a member assembled sectional view of the present utility model

Fig. 4 is a perspective bottom view of the present utility model

As depicted in figs. 1 and 2, runners 1 of the present utility model is made up of adapter sleeve 11, several chair pin 12 and bonding pad 3; Wherein: adapter sleeve 11 central authorities are the sleeve 111 of a hollow, insert for the corresponding fit of middle pipe of seat, and suitably form several arc protuberances 112 around sleeve 111, then are installed with the screw hole column 113 of right quantity in the bottom side of each arc protuberance 112 central authorities; Chair pin 12 is for can corresponding being connected the hack lever of adapter sleeve 111 each arc protuberance 112, be installed with an action roller 121 free to rotate at its end, and the head end at chair pin 12 is preset trepanning 122 corresponding to the position of above-mentioned screw hole column 113, and trepanning 122 can penetrate from lower to upper for many bolting elements 133; Bonding pad 13 has a mesopore 131 and just can wear for 111 end of sleeve section, and is provided with in addition on the bonding pad 13 with screw hole column 113 corresponding perforation 132 and from bottom to top passes and be screwed in the screw seat 113 for bolting elements 123.

During combination, as shown in Figure 3 and Figure 4, only need the head end of each chair pin 12 is mounted in each arc protuberance 112, and screw hole column 113 correspondences of each arc protuberance 112 are inserted in chair pin 12 trepannings 122 places, and bonding pad 13 from bottom to top inserted, make 111 end of sleeve section just can pass the mesopore 131 of bonding pad 13, then again with bolting element 123 from bonding pad 13 respectively bore a hole 132 and the bottom of chair pin 12 penetrate trepanning 122 inside, and establish fixingly with the mutual spiral shell of the screw thread of screw hole column 113, can be easily apace each chair pin assembling be finished.
