Description

Technical Field

[0001] The utility model relates to the technical field of spring bed steel wires, in particular to a high-elasticity and low-stress steel wire for a spring bed. Background Art

[0002] A spring bed is a bed that uses steel wire springs as a support system in the mattress. The mattress contains multiple steel wire springs. The working principle of a spring bed is based on the mechanical properties of springs, which can return to their original length after being stressed. When a person lies on a spring bed, the mattress will sink, compressing the springs on the bed, and then due to the nature of the springs recovering their own length, the mattress will return to its original shape again.

[0003] Spring beds are mainly divided into two types: non-independent pocket springs and independent pocket springs. There is no partition wall between the springs of non-independent pocket spring beds, all springs are connected to each other, the mattress has relatively poor elasticity and high hardness. On the other hand, each spring of an independent pocket spring bed is independently wrapped in a cloth bag, without interfering with each other, with more uniform support points and better comfort.

[0004] During long-term use of the steel wire spring used in the spring bed, the elasticity of the steel wire spring will decrease due to the problem of the steel wire material. In addition, due to the stress of the steel wire, the steel wire spring will collapse. Therefore, a high-elasticity and low-stress steel wire for a spring bed is proposed. The steel wire is additionally processed and an additional auxiliary structure is added to increase the elasticity of the steel wire and improve the service life of the internal steel wire spring of the spring bed. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a high-elasticity, low-stress steel wire for a spring bed, which has the advantages of good flexibility and strong practicality, and solves the problem that the elasticity of the internal steel wire of the spring bed decreases due to long-term use and the stress causes the spring bed to have a short service life.

[0006] In order to achieve the above-mentioned purpose of good flexibility and strong practicality, the utility model provides the following technical solutions: a high-elasticity, low-stress steel wire for a spring bed, comprising an inner steel wire and an outer steel wire, an isolation component arranged on the outside of the inner steel wire, and a support component arranged on the outside of the outer steel wire; the inner steel wire is processed into a continuous spiral multi-ring straight cylindrical spring structure, the inner steel wire is divided into a double-layer structure, and the outer layer of the inner steel wire is coated with a coating.

[0007] Furthermore, the outer layer steel wire is a cylindrical spring structure with continuous spiral multi-rings, and the middle width of the cylindrical spring structure formed by the spiral of the outer layer steel wire is greater than the widths at the upper and lower ends.

[0008] Furthermore, the isolation assembly includes an inner supporting bottom plate fixedly installed on the bottom of the inner steel wire, an inner top plate fixedly installed on the top of the inner steel wire, and an independent sleeve fixedly installed on the top of the inner top plate.

[0009] Furthermore, the independent sleeve is a cylindrical soft hollow material, which wraps the inner supporting bottom plate, the inner top plate and the inner steel wire inside, and the bottom of the inner supporting bottom plate and the inner bottom wall of the independent sleeve are fixedly installed.

[0010] Furthermore, the support assembly includes a bottom annular plate fixedly installed at the bottom of the outer steel wire, a base plate fixedly installed at the bottom of the bottom annular plate, a support cylinder fixedly installed at the top of the base plate, a lifting cylinder movably connected to the outside of the support cylinder, and a top annular plate fixedly installed at the top of the outer steel wire.

[0011] Furthermore, the bottom of the independent sleeve and the top of the base plate are fixedly installed, the inner side surface of the top annular plate and the side surface of the independent sleeve are slidably connected, and a buckle is provided in the middle of the side surface of the independent sleeve to be clamped with the inner wall of the lifting cylinder.

[0012] Furthermore, the side surface of the bottom annular plate and the outer side surface of the support tube are fixedly installed, and the lifting tube is wrapped around the outer side of the support tube and is slidably connected to the side surface of the support tube.

[0013] Compared with the prior art, the utility model provides a high-elasticity and low-stress steel wire for a spring bed, which has the following beneficial effects:

[0014] 1. The spring bed uses high-elasticity and low-stress steel wire. By arranging inner steel wire and outer steel wire on the top of the base plate at the same time, when the force point of the spring bed is in the gap between the springs of the spring bed, the bed surface of the spring bed will first press the top annular plate, and the fixed annular plate will press the outer steel wire. At the same time, the bottom of the outer steel wire squeezes the bottom annular plate, and the bottom annular plate receives the support of the base plate to squeeze the outer steel wire to deform. The spring structure wound with the outer steel wire will push the annular plate to push the mattress to restore its original shape again due to the characteristic of the spring restoring its own length.

[0015] 2. The spring bed uses high-elasticity and low-stress steel wire. By pressing the spring bed at the top of the spring bed, when the force point of the spring bed is at the top of the positive spring of the spring bed, the bed surface of the spring bed is forced to press the top of the independent cover, and the top of the independent cover begins to squeeze the inner top plate under force, and the inner top plate begins to press the inner steel wire. The bottom of the inner steel wire begins to deform after being supported by the inner support bottom plate. Since the spring wound by the inner steel wire needs to restore its own length, the inner steel wire pushes the inner top plate to push the mattress to restore its original shape again. The spring structure formed by the inner steel wire and the outer steel wire corresponds to the pressure generated at different positions of the mattress, thereby avoiding local overload of the spring bed and sharing the external pressure on a single spring. Multiple structures cooperate with each other to make the spring bed evenly stressed and avoid excessive local pressure, thereby solving the problem that the elasticity of the internal steel wire of the spring bed is reduced due to long-term use and the stress effect causes the spring bed to have a short service life.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-3 In this embodiment, a high-elasticity, low-stress steel wire for a spring bed includes an inner steel wire 1 and an outer steel wire 2, an isolation component 3 arranged on the outside of the inner steel wire 1, and a support component 4 arranged on the outside of the outer steel wire 2; the inner steel wire 1 is processed into a continuous spiral multi-ring straight cylindrical spring structure, the inner steel wire 1 is divided into a double-layer structure, and the outer layer of the inner steel wire 1 is coated with a coating.

[0022] A double-structure spring structure is formed by arranging an inner steel wire 1 and an outer steel wire 2. The spring structures formed by the inner steel wire 1 and the outer steel wire 2 of different widths cooperate with each other, thereby increasing the durability of the spring bed. The isolation component 3 isolates the inner steel wire 1 and the outer steel wire 2 so that they do not interfere with each other. The inner steel wire 1 is made of carbon steel with a low elastic modulus and a high yield strength. A titanium alloy or chromium alloy coating, such as titanium alloy or chromium alloy, is applied on the surface of the high carbon steel to reduce the internal stress of the spring formed by the inner steel wire 1.

[0023] In this embodiment, the outer steel wire 2 is a cylindrical spring structure with continuous spiral multi-rings, and the middle width of the cylindrical spring structure formed by the spiral outer steel wire 2 is greater than the widths at the upper and lower ends.

[0024] The main supporting structure is realized by using an outer steel wire 2 cast from high-carbon steel with good elasticity to form a cylindrical spring structure that is wide in the middle and narrow at the upper and lower ends. When used in conjunction with the inner steel wire 1, the service life of the spring bed is increased. In addition, the high-carbon steel used for the outer steel wire 2 is also added with alloy elements such as molybdenum, chromium, manganese, etc. to further improve the elasticity of the steel wire.

[0025] In this embodiment, the isolation assembly 3 includes an inner supporting base plate 31 fixedly installed at the bottom of the inner steel wire 1 , an inner top plate 32 fixedly installed at the top of the inner steel wire 1 , and an independent sleeve 33 fixedly installed at the top of the inner top plate 32 .

[0026] The inner support bottom plate 31 is provided to support the bottom of the inner layer steel wire 1 , and the inner layer top plate 32 supports the top of the spring bed, so that a spring support structure is formed inside the independent sleeve 33 .

[0027] In this embodiment, the independent sleeve 33 is a cylindrical soft hollow material, which wraps the inner support bottom plate 31, the inner top plate 32 and the inner steel wire 1 inside, and the bottom of the inner support bottom plate 31 and the inner bottom wall of the independent sleeve 33 are fixedly installed.

[0028] By wrapping the inner support bottom plate 31 , the inner steel wire 1 and the inner top plate 32 with the independent sleeve 33 , an internal independent support unit structure is formed to avoid interference between the inner steel wire 1 and the outer steel wire 2 .

[0029] In this embodiment, the support assembly 4 includes a bottom annular plate 41 fixedly installed at the bottom of the outer steel wire 2, a base plate 42 fixedly installed at the bottom of the bottom annular plate 41, a support cylinder 43 fixedly installed at the top of the base plate 42, a lifting cylinder 44 movably connected to the outside of the support cylinder 43, and a top annular plate 45 fixedly installed at the top of the outer steel wire 2.

[0030] By respectively arranging a bottom annular plate 41 and a top annular plate 45 at the upper and lower ends of the outer steel wire 2, another set of spring support structures is formed outside the independent sleeve 33, and the two sets of spring support structures cooperate with each other.

[0031] In this embodiment, the bottom of the independent sleeve 33 and the top of the base plate 42 are fixedly installed, the inner side surface of the top ring plate 45 and the side surface of the independent sleeve 33 are slidingly connected, and a buckle is provided in the middle of the side surface of the independent sleeve 33 and is clamped with the inner wall of the lifting cylinder 44.

[0032] By fixing the independent sleeve 33 and the base plate 42, the spring support structure inside the independent sleeve 33 and the spring support structure formed by the outer steel wire 2 on the outside are fixed, so that the two can cooperate with each other to support each other without relative movement. In addition, the fixation of the lifting cylinder 44 and the independent sleeve 44 allows the independent sleeve 44 to drive the lifting cylinder 44 to move up and down when it is retracted.

[0033] In this embodiment, the side surface of the bottom annular plate 41 and the outer side surface of the support tube 43 are fixedly installed, and the lifting tube 44 is wrapped around the outer side of the support tube 43 and is slidably connected to the side surface of the support tube 43.

[0034] By arranging the lifting cylinder 44 to slide on the outside of the supporting cylinder 43 , the lifting cylinder 44 has a directional moving track under the limitation of the supporting cylinder 43 .

[0035] The working principle of the above embodiment is:

[0036] By arranging the inner steel wire 1 and the outer steel wire 2 on the top of the base plate 42 at the same time, when the force point of the spring bed is in the gap between the springs of the spring bed, the bed surface of the spring bed will first press the top annular plate 45, and the fixed annular plate 45 will press the outer steel wire 2. At the same time, the bottom of the outer steel wire 2 squeezes the bottom annular plate 41, and the bottom annular plate 41 receives the support of the base plate 42 to squeeze the outer steel wire 2 to deform. The spring structure formed by the outer steel wire 2 will push the annular plate 45 to push the mattress to restore its original shape again due to the characteristic of the spring restoring its own length.

[0037] In addition, when the force point of the spring bed is at the top of the spring of the spring bed, the bed surface of the spring bed is forced to press the top of the independent cover 33, and the top of the independent cover 33 is forced to begin to squeeze the inner top plate 32, and the inner top plate 32 begins to press the inner steel wire 1. The bottom of the inner steel wire 1 begins to deform after being supported by the inner support bottom plate 31. Since the spring wound by the inner steel wire 1 needs to restore its own length, the inner steel wire 1 pushes the inner top plate 32 to push the mattress to restore its original shape again. The spring structures formed by the inner steel wire 1 and the outer steel wire 2 correspond to the pressure generated at different positions of the mattress, thereby avoiding local overload of the spring bed and sharing the external pressure on a single spring. Multiple structures cooperate with each other to make the spring bed evenly stressed and avoid excessive local pressure. This solves the problem that the elasticity of the internal steel wire of the spring bed is reduced due to long-term use and the stress effect causes the spring bed to have a short service life.
