Abstract

The utility model relates to a sponge spring strip. It comprises a long-strip sponge cylinder, and through holes are uniformly distributed on the wall of the sponge cylinder to enable the cylinder wall to form a cut flower shape. The utility model discloses can surely get required length when using, constitute a little spring, required spring in being as furniture, its low in manufacturing cost, soft and rich in enough elasticity during the use, it is comfortable to use, longe-lived.

Description

Sponge spring strip

Technical Field

The utility model relates to a sponge product, in particular to a sponge spring strip which can be used as a spring required on various furniture.

Background

As is well known, the springs used in furniture are generally made of steel wire springs or various elastic materials, such as common steel wire springs used in sofas and steel wire beds, and steel wire springs or direct sponges used in mattresses and cushions. The pillow and the back cushion also use a steel wire spring or directly use sponge. The steel wire spring is adopted, so that the cost is high, the size is large, the pressure is frequent when the spring is used, the spring can be rusted after long-term use, and the service life of the spring is influenced. The sponge is directly adopted, so that the elasticity of the sponge is often insufficient, and the use requirement is difficult to meet.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to prior art not enough, provide a sponge spring strip, can be according to the in-service use requirement, with the required length of this sponge spring strip intercepting, constitute a little spring, required spring in being used as furniture, its low in manufacturing cost, soft and rich in enough elasticity during the use, it is comfortable and suitable to use, longe-lived.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a sponge spring strip, includes a rectangular shape sponge section of thick bamboo, its characterized in that: the wall of the sponge cylinder is evenly distributed with through holes to make the cylinder wall in a cut flower shape.

The through holes on the cylinder wall are diamond-shaped through holes, so that the cylinder wall forms a twill grid-shaped cut flower shape.

The cut flower shape may have spaced widening strips.

The longitudinal length a of the diamond-shaped through hole is 3-10 mm, and the interval between two longitudinally adjacent holes is 2-8 mm.

The diameter d of the outer wall of the sponge cylinder is 4-20 cm, and the wall thickness b of the sponge cylinder is 1-5 cm.

The longitudinal length h of the sponge cylinder is the length of the raw material sponge, and the required length is cut when the sponge cylinder is applied.

The raw material of the sponge spring strip can be common sponge, slow-return memory sponge or high-resilience sponge according to the requirement.

Compared with the prior art, the utility model, have following obvious substantive characteristics and technological progress: the utility model discloses sponge spring strip can cut into segment shape sponge according to actual need, utilizes the elasticity of sponge, constitutes soft and be rich in elastic spring. The sponge cylinder wall is formed into a cut flower shape by adopting a cut flower net-drawing forming process, so that the elasticity of the sponge is greatly increased. Spacing widening strips can be added in the shape of the cut flower, so that the supporting hardness of the sponge cylinder can be improved. The utility model discloses can choose for use different raw and other materials sponge and unidimensional barrel size and cut flower shape and size to and choose for use unidimensional interval widening strip, thereby can constitute the sponge spring of unidimensional, different elasticity and different support hardness, low in manufacturing cost, longe-lived, it is comfortable to use.

Fig. 2 is a schematic structural view of a sponge spring strip having spaced-apart widening strips in the shape of a cut flower.

Fig. 3 is an oblique view of an embodiment of the present invention.

Detailed Description

The preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings:

the first embodiment is as follows:

referring to fig. 1-3, the sponge spring strip comprises a strip-shaped sponge cylinder (1), and through holes (2) are uniformly distributed on the wall of the sponge cylinder (1) to form a wall cylinder into a cut flower shape (3).

Example two: this embodiment is substantially the same as the first embodiment, and is characterized in that:

the perforation (2) is a diamond perforation, so that the cylinder wall forms a twill grid-shaped cut flower shape (3).

Example three: this embodiment is basically the same as the second embodiment, and is characterized in that:

the cut flower shape (3) is provided with spacing widening strips (4).

Example four: this embodiment is substantially the same as the second or third embodiment, and is characterized in that:

the longitudinal length a of the rhombic through holes (3) is 3-10 mm, and the interval between every two adjacent longitudinal holes is 2-8 mm. The diameter d of the outer wall of the sponge cylinder (1) is 4-20 cm. The wall thickness b of the sponge cylinder (1) is 1-5 cm. The longitudinal length h of the sponge cylinder (1) is the length of the raw material sponge, and the required length is cut when the sponge cylinder is applied, so that the sponge cylinder can be made into springs in mattresses, pillows, mattresses, sofa cushions and back cushions.
