Description
Technical Field
The utility model belongs to the technical field of the technique of spring and specifically relates to a sofa pad is with snakelike spring structure is related to.
Background
Currently, a serpentine spring refers to a spring that is bent in the shape of a serpentine.
The serpentine spring for the existing sofa cushion is generally fastened to the sofa frame at two ends of the serpentine spring, so that the serpentine spring is fixed on the sofa frame.
The above prior art solutions have the following drawbacks: when a user uses the sofa, pressure is applied to the serpentine spring, so that the two ends of the serpentine spring are subjected to large force, and if the friction force between the two ends of the serpentine spring and the sofa support is small, the serpentine spring is easy to fall off from the sofa support.
SUMMERY OF THE UTILITY MODEL
The utility model provides a sofa pad is with snakelike spring structure, has the effect that reduces the probability of droing not enough to prior art exists.
In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides a sofa cushion uses serpentine spring structure, includes serpentine spring portion, sets up the fixed part at serpentine spring portion both ends, serpentine spring portion includes that a plurality of is the basis spare of U-shaped, and is adjacent fixed connection between the basis spare, be provided with crooked spacing portion on the fixed part.
Through adopting above-mentioned technical scheme, the workman fixes the fixed part on the sofa support, and is spacing on the sofa support with the fixed part through spacing portion, when taking place to slide between fixed part and the sofa support, spacing portion is injectd the position of fixed part for the fixed part is difficult to take place to remove, thereby has reduced the probability that the fixed part drops from the sofa support.
The utility model discloses further set up to: the middle part of the basic part is provided with a reinforcing bulge, and the reinforcing bulge is positioned on two sides of the basic part.
Through adopting above-mentioned technical scheme, strengthen bellied setting and make the thickness of basic piece increase, when the basic piece received tensile, the difficult fracture that takes place of basic piece self.
The utility model discloses further set up to: the width of the middle part of the basic part is larger than the width of the two ends of the basic part.
Through adopting above-mentioned technical scheme, the width in basic member middle part is great to the intensity in the middle part of basic member rather than is higher, because basic member when taking place deformation, the atress in basic member middle part is great to make the difficult fracture that takes place of basic member.
The utility model discloses further set up to: and a connection reinforcing block is fixedly connected at the joint of the adjacent base pieces.
Through adopting above-mentioned technical scheme, the setting up of connecting the boss makes the joint strength between the basic member obtain promoting to make the difficult emergence fracture of snakelike elastic component.
The utility model discloses further set up to: the both ends cover of basis spare is equipped with the beaded finish, the beaded finish with basis spare fixed connection.
Through adopting above-mentioned technical scheme, the intensity at basic piece both ends has been strengthened in setting up of beaded finish to make the difficult fracture of emergence of basic piece self.
The utility model discloses further set up to: a plurality of friction grooves are formed in the limiting portion.
Through adopting above-mentioned technical scheme, the setting up of friction recess makes the roughness of the contact surface between spacing portion and the sofa support rise to it is more firm to make the connection between spacing portion and the sofa.
The utility model discloses further set up to: the snake-shaped elastic part, the fixing part and the limiting part are all made of carbon steel.
By adopting the technical scheme, the carbon steel has stronger hardness and is convenient to process into the spring.
The utility model discloses further set up to: protective layers are arranged on the snake-shaped elastic part, the fixing part and the limiting part and made of zinc.
Through adopting above-mentioned technical scheme, the protective layer of zinc system can play better guard action, makes snakelike elastic component, fixed part and spacing difficult the rusting.
To sum up, the utility model discloses following beneficial effect has:
through setting up fixed part and spacing portion for be connected between serpentine spring and the sofa support more inseparable, even have the trend that breaks away from each other between fixed part and the sofa support, spacing portion also can be better prescribes a limit to the position of fixed part, makes it difficult to break away from.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Referring to fig. 1 and 2, for the utility model discloses a serpentine spring structure for sofa cushion, including serpentine elastic part 1, serpentine elastic part 1 includes that a plurality of is the basic component 11 of U-shaped, fixed connection between the adjacent basic component 11, and the junction fixed connection of adjacent basic component 11 connects boss 12.
Fixed part 2 that the fixed part 2 that is S-shaped is fixedly connected with in 1 both ends of snakelike elastic component, is provided with crooked spacing portion 3 on the fixed part 2, and spacing portion 3 is C shape, has seted up a plurality of cross-section for rectangular friction recess 31 on the spacing portion 3.
The middle part of basic piece 11 is provided with the cross-section and strengthens protruding 4 for hemisphere, strengthens protruding 4 both sides that are located basic piece 11, and the middle part width of basic piece 11 is greater than the width at basic piece 11 both ends, and the both ends cover of basic piece 11 is equipped with beaded finish 5, beaded finish 5 and basic piece 11 fixed connection.
Referring to fig. 1 and 3, the snake-shaped elastic part 1, the fixing part 2 and the limiting part 3 are all made of carbon steel, the protective layer 6 is arranged on the snake-shaped elastic part 1, the fixing part 2 and the limiting part 3, and the protective layer 6 is made of zinc.
The implementation principle of the embodiment is as follows: the worker installs the fixing portion 2 on the sofa support, and the limiting portion 3 abuts against the sofa support at this time. When the fixing part 2 is separated from the sofa support, the limiting part 3 is tightly abutted to the sofa support, and the friction groove 31 increases the friction force between the limiting part 3 and the sofa support, so that the movement of the fixing part 2 is limited, and the serpentine spring is stably positioned on the sofa support.
The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
