Description

TECHNICAL FIELD

[0001] The utility model relates to furniture technical field especially, relate to a handrail compression mechanism and have its sofa. BACKGROUND

[0002] In the modern furniture market, as a common household item, the design and functionality of the sofa have always been the focus of attention for both consumers and manufacturers. Traditional sofa design often focuses on elegance, comfort and durability of the appearance, but there are certain limitations in transportation and storage, especially the volume of the sofa armrest.

[0003] Traditional sofa armrests are usually designed in a fixed manner, with the armrest part closely connected to the sofa main frame, which cannot be detached or compressed. Although this design ensures the stability and overall aesthetics of the sofa during use, it is not flexible and convenient when the sofa needs to be transported over long distances or stored in limited space. The large volume of the armrest not only increases transportation costs, but also may not be successfully delivered to the destination due to space limitations, causing inconvenience to consumers and businesses.

[0004] To solve this problem, some detachable sofa armrest designs have gradually appeared in the market, but these designs often require complex connection structures on the sofa main body, which not only increases the manufacturing cost, but also may affect the overall aesthetics and durability of the sofa. In addition, even if the armrest can be detached, its volume is still large, which is not convenient for further compression and storage. SUMMARY

[0005] To overcome at least one of the above-mentioned deficiencies of the prior art, the utility model provides a handrail compression mechanism and a sofa with the same. The problem of large volume of the sofa armrest can be solved.

[0006] The utility model adopts the technical scheme that:

[0007] A handrail compression mechanism, comprising: a first connecting plate having a first connecting piece disposed thereon; a second connecting plate having a second connecting piece disposed thereon; a telescopic rod set connected between the first connecting piece and the second connecting piece; when the telescopic rod set is compressed, the first connecting plate and the second connecting plate move towards each other; when the telescopic rod set is extended, the first connecting plate and the second connecting plate move away from each other; a limiting assembly connected to the telescopic rod set for avoiding compression of the telescopic rod set when the telescopic rod set is in the extended state.

[0008] By adopting the above scheme, since the armrest can be compressed through the compression of the telescopic rod set, the overall volume of the sofa is greatly reduced, thereby reducing the transportation cost and difficulty, and the compressed armrest occupies less space when the sofa is stored, which is particularly important for families or warehouses with limited space; through the design of the telescopic rod set and the limiting assembly, the user can easily realize the compression and expansion of the armrest without complex operation or tools.

[0009] Further, the first connecting piece includes a first plate and a second plate extending towards the second connecting plate; and the second connecting piece includes a third plate and a fourth plate extending towards the first connecting plate.

[0014] By adopting the above scheme, the telescopic range between the first connecting rod and the second connecting rod, and the telescopic range between the third connecting rod and the fourth connecting rod can be limited by the limiting piece, thereby ensuring the stability of the overall telescopic.

[0015] Further, the third sliding groove includes a first sliding segment, a second guiding segment and a third clamping segment sequentially connected, the included angle between the first sliding segment and the second guiding segment is obtuse, and the included angle between the second guiding segment and the third clamping segment is acute or right angle.

[0016] By adopting the above scheme, the middle part of the second connecting rod can slide in the first sliding segment, the second guiding segment and the third clamping segment in sequence, so that the extension and retraction range of the telescopic rod set and the stability of the extension and retraction process are limited.

[0017] Further, the end of the first sliding segment is provided with a first abutting part for abutting with the middle part of the second connecting rod when the telescopic rod set is compressed.

[0018] By adopting the above scheme, the stability of the compression state of the telescopic rod set can be maintained.

[0027] In summary, the sofa armrest compression mechanism and the sofa provided with the same have the following technical effects:

[0028] 1. By the design of the armrest compression mechanism, the sofa armrest can be compressed before transportation, thereby significantly reducing the overall volume of the sofa. This not only reduces the space required by the transportation vehicle, but also reduces the fuel consumption and labor cost during transportation. This effect is particularly obvious for long-distance transportation or cross-country transportation;

[0029] 2. The compressed armrests allow the sofa to occupy less space when stored, which is particularly important for limited spaces such as homes, warehouses, or sales showrooms. It allows users or businesses to store more sofas in the same space, improving space utilization;
