Abstract

The utility model discloses a device for automatically adjusting the angle of a leaning rod for a chair back, which is mainly composed of two abutting rod pieces, two fixed seats, an elastic sheet and a thick spring, wherein, the two fixed seats are respectively fixed in the two abutting rod pieces, and inserting slots are formed on the opposite ends of the two fixed seats; both ends of the elastic sheet are fixedly inserted into the inserting slots of the two fixed seats; the thick spring is fixed out of the abutting position of the two rod pieces. The device replaces a steel wire bundle and a thin spring in the prior art by the elastic sheet, so the whole device has the advantages of convenient and easy assembling operation, time saving and labor saving.

Description

The angle automatic regulating apparatus of chair back rod

The utility model belongs to tourism or camp appliances, relates to a kind of angle automatic regulating apparatus of chair back rod.

In the prior art, the angle automatic regulating apparatus that a kind of chair back rod arranged mainly is made up of rod member 1, steel tendon 2, hairspring 3 and the bulky spring 4 of two sections butt joints as shown in Figure 4.Wherein, steel tendon 2 interts in the rod member 1 of two sections butt joints, and two sections rod member 1 rigidity of butt joint are strengthened.Hairspring 3 is enclosed within on the steel tendon 2, is fixed on the joint inside of two sections rod members 1 by slipmat 5.Bulky spring 4 is fixed on the joint outside of two sections rod members 1 by slipmat 5, and hairspring 3 and bulky spring 4 match, and make two sections rod members 1 of butt joint have certain elasticity.

When this device is used on the leisure chaise longue, when the people is sitting on the leisure chaise longue, when leaning on backward, the chair back is imposed on different pressure, and suitable elastic bending promptly takes place with this pressure in two sections rod members 1 of chair back rod, adapts with the back of the body appearance with human body, the people is felt comfortably cool, thereby banish the feeling of languor.

During this device assembling, need hairspring 3 is enclosed within on the steel tendon 2, again steel tendon 2 and hairspring 3 are interted in the lump in the rod member 1 of two sections butt joints, then, respectively steel tendon 2 and hairspring 3 are fixed in the rod member 1 of two sections butt joints, at last, bulky spring 4 is fixed on the joint outside of two sections rod members 1.Wherein, the fixing comparatively inconvenience of steel tendon 2 and hairspring 3, so, the also comparatively inconvenience of this device assembly operation, time-consuming also effort.

The purpose of this utility model is to provide the angle automatic regulating apparatus that a kind of assembly operation is convenient, be easy to chair back rod.

For reaching above-mentioned purpose, the utility model mainly is made up of the rod member of two sections butt joints, two holders, shell fragment and bulky springs; Two holders are separately fixed at the rod member inside of two sections butt joints, all form slot on the opposite end of two holders; The two ends of shell fragment fixedly are plugged in the slot of two holders; Bulky spring is fixed on the joint outside of two sections rod members.

Form on the slot of said fixing seat and run through slotting through hole, corresponding this through hole in the two ends of shell fragment forms perforation, corresponding this through hole and perforation then form fixing hole on the rod member of two sections butt joints, rivet passes fixing hole, through hole and perforation, holder and shell fragment is fixed in the lump the joint inside of two sections rod members.

After adopting said structure, the utility model replaces the steel tendon and the hairspring of prior art with shell fragment, shell fragment has the double action of steel tendon and hairspring in the prior art, shell fragment had both resembled and had interted in the rod member of two sections butt joints the steel tendon, two sections rod member rigidity of butt joint are strengthened, resemble the joint inside that is fixed on two sections rod members the hairspring again, match, make two sections rod members of butt joint have certain elasticity with bulky spring.When the utility model is used on the leisure chaise longue, can reach as prior art the effect that----" adapts with the back of the body appearance of human body, the people felt comfortably cool, thereby banish the feeling of languor ".

During the utility model assembling, two ends with shell fragment are fixed in the slot of two holders earlier, again two holders are separately fixed at the rod member inside of two sections butt joints, thus, realize that shell fragment is fixed on the rod member inside of two sections butt joints, at last, bulky spring 4 is fixed on the joint outside of two sections rod members 1.Wherein, fixedly comparing of fixing and the prior art steel tendon and the hairspring of shell fragment, simple, easily, so whole device assembly operation is convenient, easy, save time and laborsaving.

Below in conjunction with drawings and Examples, the utility model is further described.

Fig. 1 is a three-dimensional exploded view of the present utility model;

Fig. 2 is an assembled sectional view of the present utility model;

Fig. 3 is user mode figure of the present utility model;

Fig. 4 is a stereogram of commonly using product.

See also Fig. 1, cooperate shown in Figure 2ly, the utility model mainly is made up of the rod member 1 of two sections butt joints, two holders 6, three shell fragments 7 and bulky spring 4, and wherein, the sheet number of shell fragment 7 is not subjected to the restriction of this example, requires to be as the criterion to satisfy certain rigid and elasticity.

Two holders 6 are separately positioned on rod member 1 inside of two sections butt joints, all form slot 61 on the opposite end of two holders 6, form on the slot 61 and run through slotting through hole 62.

The two ends of three shell fragments 7 fixedly are plugged in the slot 61 of two holders 6, and the corresponding through hole 62 in the two ends of each shell fragment 7 forms perforation 71.

Corresponding through hole 62 and perforation 71 then form fixing hole 11 on the rod member 1 of two sections butt joints, and rivet 8 passes fixing hole 11, through hole 62 and bores a hole 71, holder 6 and three shell fragments 7 are fixed in the lump the joint inside of two sections rod members 1.

Bulky spring 4 is fixed on the joint outside of two sections rod members 1 by slipmat 5.

The utility model replaces the steel tendon 2 and the hairspring 3 of prior art with shell fragment 7, in the time of on being used in leisure chaise longue, as shown in Figure 3, the people is sitting on the leisure chaise longue, leans on backward, the chair back is imposed on different pressure, two sections rod members 1 of chair back rod are promptly with this pressure, and the suitable elastic bending of elasticity generation by three shell fragments 7 and bulky spring 4 adapts with the back of the body appearance with human body, the people is felt comfortably cool, thereby banish the feeling of languor.
