Detailed Description

The present invention will be further explained with reference to the accompanying drawings:

with reference to the accompanying drawings: the office chair with the integrally connected armrests, the chair back and the chair seat comprises a chair seat 1, a chair back 2 and two armrests 3, wherein the chair back 2 is provided with an outer frame 21, and the chair seat 1 and the two armrests 3 are both arranged on the lower section part of the outer frame 21 and are connected through at least one common first connecting piece 4.

In order to realize the integrated connection of the seat 1, the armrests 3 and the chair back 2, a first mounting cavity 21-a is formed in the middle of the lower section of the outer frame 21 and used for mounting the seat 1, second mounting cavities 21-b are further formed in the left side and the right side of the lower section of the first mounting cavity 21-a and used for mounting the two armrests 3, the transverse center line of the first mounting cavity 21-a and the transverse center lines of the two second mounting cavities 21-b are the same center, and the arrangement has two functions, so that the installation is convenient, the first mounting cavity 21-a and the second mounting cavities 21-b can be used for the quick insertion of the seat 1 and the armrests 3, the assembly convenience can be improved, and the assembly efficiency of the chair can be obviously improved; on the other hand, the seat can be connected by using the common first connecting piece 4, the first mounting cavity 21-a and the two second mounting cavities 21-b are both arranged on the outer frame 21 of the seat back 3, and the transverse center lines of the second mounting cavity 21-a and the two second mounting cavities 21-b are the same center, so that when the seat 1 and the armrest 3 are fixed in the first mounting cavity 21-a and the two second mounting cavities 21-b, only one first connecting piece 4 is needed without adopting other connecting pieces, the assembly efficiency is improved, and the cost is reduced.

In order to facilitate the installation of the first connecting piece 4, at least one first connecting hole 5 transversely penetrating through the first connecting piece 4 is formed between the first installation cavity 21-a and the two second installation cavities 21-b, each first connecting hole 5 is used for inserting the corresponding first connecting piece 4 and is a common connecting point between the armrest 3, the chair back 2 and the chair seat 1, the first connecting piece 4 can be a screw rod, the installation mode of the screw rod is that the screw rod is screwed through a nut after being inserted, an elastic gasket can be added for improving the tightness, the first connecting hole 5 has the advantages of convenient processing and installation, no excessive structure is needed to be added, in the installation stage, the screw rod only needs to pass through, simultaneously, the number of the first connecting holes 5 can be one, also can be two, three or even more, when one is selected, the connection stability is not sufficient, the chair seat 1 can be loosened after the use for many times, when two connection holes are selected, the connection stability is good, so in order to improve the efficiency, the two first connection holes 5 are selected to be formed.

In order to increase the connection stability of the seat 1, the bottom of the first installation cavity 21-a is further provided with a plurality of second connection holes 21-a1, the second connection holes 21-a1 are connected with the seat 1 through the second connecting pieces 6 and are another connection point, when a user sits on the seat 1, according to different sitting posture habits, the sitting posture of part of the user is inclined forward, namely the hip occupies less than half of the area of the seat 1, so that the stress point of the seat 1 is concentrated at the front part, and after long-time sitting is caused according to the connection mode of the seat 1 and the first connecting pieces, the seat 1 inclines downwards, so that the user can slide downwards after sitting on the seat, the sitting posture of the user needs to be adjusted frequently, the experience is reduced, in order to meet the sitting posture requirements of the user and avoid the sitting posture, the bottom of the seat 1 is limited, utilize second connecting hole 21-a1 and second connecting piece 6 to realize, second connecting piece 6 also chooses the screw rod for use equally, screws through the nut, improves the fastening and can also add the elastic gasket to avoid the condition that the downward sloping can appear in seat support 1, improve user's experience and feel.

The resistance of the seat 1 is increased, the cavity opening of the first installation cavity 21-a is gradually reduced to the cavity tail, the plurality of reinforcing ribs 6 which are distributed at equal intervals along the transverse direction of the first installation cavity 21-a are arranged at the cavity tail, the seat 1 is provided with the tail plate 11, the tail plate 11 distinguishes the connection of the seat 1, namely, a part of the tail plate is connected with the outer frame 21, and a part of the tail plate is connected with the seat cushion, according to the structure of the first installation cavity 21-a, the tail part of the tail plate 11 is not attached to the tail part of the first installation cavity 21-a, but is abutted to the tail part of the tail plate 11 through the reinforcing ribs 6, so that one tail plate 11 can be provided, when a user sits on the seat cushion, namely the seat 1, the bearing capacity for the weight of the user is correspondingly increased, and meanwhile, the internal strength of the first installation cavity 21-a is correspondingly increased.

The armrest 3 can stably exist in the second mounting cavity 21-b before the first connecting piece 5 is fastened for convenience of mounting, the second mounting cavity 21-b is provided with two first inserting parts 21-b1, the inserting end of the armrest 3 is provided with two plugs 31 and is inserted into the corresponding first inserting parts 21-b1, the first connecting hole 5 is located in the corresponding first inserting part 21-b1, the plugs 31 are matched with the shapes of the first inserting parts 21-b1, and therefore after the armrest is inserted, the plugs 31 are in friction fit with the first inserting parts 21-b1, so that the plugs 31 stably exist in the first inserting parts 21-b1, free shaking is avoided, later fastening work can be reduced, and assembly of the seat can be completed by a single person.

Further perfection, a distance is reserved between the inlet of the second installation cavity 21-b and the first inserting part 21-b1 to form a second inserting part 21-b2, a thickening layer 31-a is further arranged at the inserting end of the handrail 3 and around the two plugs 31, and based on the positioning before the plugs 31 are fastened with the first inserting part 21-b1, the friction fit at one position is changed into two positions by adopting the structure, so that the positioning effect of the handrail 3 when the handrail is inserted into the second installation cavity 21-b is better.

While the invention has been shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the scope of the appended claims.
