Description

Sofa support

Technical Field

The utility model relates to the technical field of furniture, in particular to sofa support.

Background

The sofa is very common furniture and is widely applied to occasions such as family living rooms, hotels, business conferences and the like. The sofa has comfortable sitting feeling and variable shape, can adapt to various decoration styles, and is popular with people.

The general sofa all can use serpentine spring, because serpentine spring elasticity is good, long-lived, but generally fix mutually through the flat nail between the both ends of serpentine spring and the wooden skeleton, when sofa live time overlength back, the phenomenon that the flat nail is difficult to appear becoming flexible can lead to the condition that serpentine spring drops to take place like this, has influenced sofa's life.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a sofa support for the connection between snake spring and the wooden skeleton is more firm.

The above technical purpose of the present invention can be achieved by the following technical solutions:

a sofa support comprises a first frame, a second frame and a serpentine spring, wherein the first frame is provided with a first fixing rod, a second fixing rod, a third fixing rod and a fourth fixing rod, tenon-and-mortise assemblies are arranged among the first fixing rod, the second fixing rod, the third fixing rod and the fourth fixing rod, the first fixing rod, the second fixing rod, the third fixing rod and the fourth fixing rod are connected through a tenon-and-mortise mechanism, a reinforcing rod is arranged in the first frame, two ends of the reinforcing rod are respectively and fixedly connected with the first fixing rod and the third fixing rod, the serpentine springs are arranged into a plurality of numbers and are arranged between the second fixing rod and the reinforcing rod side by side, two ends of the serpentine spring are respectively and fixedly connected with a limiting assembly between the first fixing rod and the third fixing rod, two ends of the serpentine spring are respectively connected with the first fixing rod and the third fixing rod through a limiting assembly, spacing subassembly includes expansion micelle, snake spring clip and screw, seted up on the dead lever with expansion micelle size assorted shrinkage pool just the expansion micelle place in the shrinkage pool, the snake spring clip set up in on the expansion micelle just seted up on the snake spring clip with screw assorted screw hole, the screw passes the screw hole and with the expansion micelle is threaded connection, two fixed connection of frame in one side of frame.

By adopting the technical scheme, when the serpentine spring is stressed and elastically deforms downwards, the two ends of the serpentine spring can provide an oblique downward force for the serpentine spring clamp, and at the moment, because when the screw passes through the serpentine spring clamp and is screwed into the expansion colloidal particles, the expansion colloidal particles can be extruded by the screw and tightly abut against the inner wall of the concave hole, therefore, when the screw is forced upwards from the serpentine spring clamp, because the teeth outside the expanded colloidal particles are tightly engaged with the inner wall of the concave hole, the friction is increased, so that the screw is not easy to loosen, the serpentine spring is firmer, and meanwhile, the bandages are arranged on the second fixing rod and the fourth fixing rod, the process of pushing down under the stress of the snake spring plays a certain role in buffering, thereby avoiding the snake spring from influencing the service life of the snake spring due to overlarge stress, and moreover, the arrangement of the steel wire rope not only disperses the pressure applied to a part of the snake spring, but also avoids the overlarge elastic deformation of the snake spring after the snake spring is applied to the pressure.

Preferably, a connecting hook is arranged on the snake spring clamp on one side of the fixing rod, and one end of the snake spring is sleeved at the bending part of the connecting hook.

By adopting the technical scheme, when the distance of the serpentine spring is smaller than the distance between the first fixing rod and the third fixing rod, the connecting hook can be arranged on the serpentine spring clamp, and the serpentine spring can be fixed and connected.

Preferably, the mortise and tenon joint mechanism comprises a tenon, a mortise and a wood pin, the tenon is arranged at two ends of the first fixing rod and the third fixing rod, the mortise is arranged at two ends of the second fixing rod and the fourth fixing rod, the tenon is inserted into the mortise, and the wood pin is inserted into the joint of the tenon and the mortise.

Adopt above-mentioned technical scheme, set up tenon fourth of the twelve earthly branches structure, not only can play and connect four dead levers, make it constitute integrative effect, do not need outside flat nail to fix once more moreover, practiced thrift the cost to a certain extent.

Preferably, a first bandage is arranged in the middle of the second fixing rod, one end of the first bandage bypasses a serpentine spring close to the first fixing rod and is fixed with the first fixing rod, a second bandage is arranged in the middle of the reinforcing rod, and one end of the second bandage bypasses a serpentine spring close to the reinforcing rod and is fixed with the reinforcing rod.

By adopting the technical scheme, the bandages arranged on the second fixing rod and the fourth fixing rod play a certain buffering role in the process of pressing the serpentine spring under stress, so that the service life of the serpentine spring is prevented from being influenced by overlarge stress.
