Abstract

The utility model relates to a chair fitting for assembling a chair. An armrest pipe is respectively provided on the left and the right armrest racks; the front ends of the pipe orifices of the seat frame transverse pipes are respectively inwardly protruded to form hook rings surrounding the pipe orifices; a plastic inner stopper is respectively and correspondingly push into each pipe orifice; the outer diameter of the choked pipe is equal to the inner diameter of the seat frame transverse pipe; and serrated pawls are provided on the outer wall of the choked pipe and clamped by the hook rings. Thus, the seat frame can be separately packed with the left and the right armrest racks, so as to remarkably reduce space for transportation, and reduce transportation cost.

Description

A kind of chair

The utility model relates to being used on the chair and assembles the accessory of the assembly of chair.

The present chair that constitutes by metal framework on the market, what the connection of its assembly was all adopted is the mode of welding, as shown in Figure 1, mounting transverse tube 3,4 connects with the mode of left arm-rest frame 1, the welding of right arm-rest frame 2 usefulness, thereby mounting 13 is connected and fixed with left and right arm-rest frame; From Fig. 2, also be that the partial enlarged drawing of the A part of Fig. 1 sees that point of contact 101 is one of them solder joint.This structure has increased the step of welding on production process, process is more, and each parts of the chair of finished product can not be taken apart, take more space in transportation, and so both inconvenient, cost is also high.

The purpose of this utility model is to be provided for the fixedly a kind of new structure of chair, assembles the assembly of chair with accessory.

For achieving the above object, the utility model is achieved in that a kind of chair, comprises left arm-rest frame, right arm-rest frame, mounting transverse tube, and mounting transverse tube two ends are the mouth of pipe, it is characterized in that: be respectively equipped with handrail tube on left arm-rest frame and the right arm-rest frame; The front end difference inwardly protruding of the mouth of pipe forms the shackle around the mouth of pipe; The mouth of pipe can correspondingly insert in each handrail tube; Filling in respectively correspondence in the plastic cement fills in each mouth of pipe.

The plug external diameter of pipe of plug equates with mounting transverse tube internal diameter in the plastic cement; Plug pipe outer wall is provided with zigzag pawl, and pawl is blocked by shackle; Gag can cover handrail tube; Gag has a step can cover the mouth of pipe, and the plug pipe that narrows under the step places in the mouth of pipe.

As from the foregoing, adopt the utility model of this new construction, the mounting of the chair of finished product can separately be packed with left and right arm-rest frame, before using, the user can at an easy rate mounting be connected and fixed with plug in the plastic cement with left and right arm-rest frame, so both saved the manufacturing step of mounting transverse tube with left and right arm-rest frame welding, process still less, reduced manufacturing cost, each parts of chair of finished product also can separate packed and transported simultaneously, significantly reduced the space that transportation occupies, greatly reduced cost of transportation because of eating this.

Fig. 1 is the user mode figure of current chairs.

Fig. 2 is the partial enlarged drawing of the A portion of Fig. 1.

Fig. 3 is a partial exploded view of the present utility model.

Fig. 4 is a local B-B profile of the present utility model.

Below in conjunction with accompanying drawing, the utility model is further described.As shown in Figure 3: a kind of chair, comprise left arm-rest frame (1), right arm-rest frame (2), mounting transverse tube (3,4) two ends are respectively the mouth of pipe (31,32) and the mouth of pipe (41,42); , it is characterized in that: be respectively equipped with handrail tube (5,6) and handrail tube (7,8) on left arm-rest frame (1) and the right arm-rest frame (2); The front end difference inwardly protruding of the mouth of pipe of mounting transverse tube (3) forms the shackle (33) around the mouth of pipe; The mouth of pipe (31), the mouth of pipe (41) can correspondingly insert in handrail tube (5) handrail tube (6), and the mouth of pipe (32), the mouth of pipe (42) can correspondingly insert in handrail tube (7), the handrail tube (8); In the plastic cement in plug (9), the plastic cement in plug (10), the plastic cement in plug (11) and the plastic cement plug (12) respectively correspondence fill in the mouth of pipe (31), the mouth of pipe (41) mouth of pipe (32) and the mouth of pipe (42).

As shown in Figure 4, plug pipe (93) external diameter of plug (9) equates with mounting transverse tube (3) internal diameter in the plastic cement; Plug pipe (93) outer wall is provided with zigzag pawl, and pawl is blocked by shackle (33); Gag (91) can cover handrail tube (5); Gag (91) has a step (92) can cover the mouth of pipe (31), and the plug pipe (93) that narrows under the step (92) places in the mouth of pipe (31).

Like this, the plug external diameter of pipe equates that with mounting transverse tube internal diameter plug pipe (93) can insert in the mouth of pipe (31), and; Plug pipe (93) outer wall is provided with zigzag pawl, and pawl is blocked by shackle (33), and handrail tube is welded on the left and right arm-rest frame, so plug has been connected and fixed the mounting transverse tube in the plastic cement with left and right arm-rest frame.

The mounting of the chair of finished product can separately be packed with left and right arm-rest frame, before using, the user can at an easy rate mounting be connected and fixed with plug in the plastic cement with left and right arm-rest frame, each parts of the chair of finished product also can separate packed and transported like this, significantly reduced the space that transportation occupies, greatly reduce cost of transportation because of eating this, also saved simultaneously the manufacturing step of mounting transverse tube with left and right arm-rest frame welding, process has still less reduced manufacturing cost.
