Description

Technical Field

[0001] The utility model relates to the technical field of open springs, in particular to a high-safety open spring. Background Art

[0002] ‌An open spring is a spring design characterized by an open design at both ends of the spring, without knots at the end faces. A single spring has good vibration performance and can change according to different pressures, thus fitting the human body better. Therefore, open springs are usually used in mattress manufacturing.

[0003] Most of the springs at the bottom of ordinary mattresses are usually used by connecting single springs in series. Since a single spring provides weak support for the body during use, its service life will be shortened when subjected to a large pressure, and it is easy to pierce the mattress, resulting in low safety performance. Therefore, we provide a high-safety open spring. Content of the Utility Model

[0004] The purpose of the utility model is to provide a high-safety open spring to solve the problems raised in the above background art that most of the springs at the bottom of ordinary mattresses are used by connecting single springs in series. Since a single spring provides weak support for the body during use, its service life will be shortened when subjected to a large pressure, and it is easy to pierce the mattress, resulting in low safety performance. To achieve the above purpose, the utility model provides the following technical solution: A high-safety open spring, including a fixed plate, a protection component is arranged on the top of the fixed plate. The protection component includes a sleeve, the sleeve is fixedly connected to the top of the fixed plate, a protection tube is movably connected to the inner wall of the sleeve, the protection tube is fixedly connected to the top of the fixed plate, a first spring is fixedly connected to the bottom of the protection tube, a movable tube is fixedly connected to the top of the first spring, a sliding block is fixedly connected to the inner wall of the movable tube, a limiting groove is opened on the side surface of the protection tube, and the sliding block is slidably connected to the inner wall of the limiting groove. By installing the protection component, when the second spring in the mattress is subjected to pressure, part of the pressure can be shared by the first spring in the protection tube. At the same time, when the first spring is deformed under pressure, the sliding block in the movable tube will move in the limiting groove, thereby increasing the friction during movement, further reducing the pressure on the first spring and the second spring, so that its service life can be maintained even when subjected to a large pressure. At the same time, the movable tube and the anti-piercing tube at the top can also prevent the first spring from piercing the mattress during use, thereby increasing the safety performance of the first spring.

[0005] Further preferably, a second spring is fixedly connected to the top of the sleeve, the other end of the second spring is fixedly connected to a connection head, and the connection head is fixedly connected to the bottom of the movable tube.

[0006] Further preferably, a fixing component is provided on one side of the fixing plate. The fixing component includes a fixing block fixedly connected to one side of the fixing plate. A connecting plate is fixedly connected to one side of the fixing block. A fixing ring is fixedly connected to one side of the connecting plate. A fixing spring is movably connected to the inner wall of the fixing ring. The fixing spring is fixedly connected to one side of the connecting plate, and the other end of the fixing spring is fixedly connected to a fixing strip. By installing the fixing component, pressure can be applied to the fixing springs on both sides of the connecting plate first to deform them, and then the fixing block and the connecting plate can be pushed into the connecting port. When the fixing strip on one side of the fixing spring enters the bottom of the connecting port, the fixing spring will restore its deformation, thereby pushing the fixing strip into the fixing groove, so that multiple fixing plates can be connected together, better for series connection, improving the connection strength between the first spring and the second spring, and increasing the practicability of the device.

[0007] Further preferably, a connecting port is provided on the other side of the fixing plate, and a fixing groove is provided inside the connecting port.

[0009] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0010] In the present utility model, by installing the protection component, when the second spring in the mattress is under pressure, part of the pressure can be shared by the first spring in the protection tube. At the same time, when the first spring deforms under pressure, the sliding block in the movable tube will move in the limiting groove, thereby increasing the friction during movement, further reducing the pressure on the first spring and the second spring, so that it can maintain its service life even under greater pressure.

Specific embodiments

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figures 1 - 5, the present utility model provides a technical solution: a high - security opening spring, which includes a fixing plate 1. A protection component 2 is arranged on the top of the fixing plate 1. The protection component 2 includes a sleeve 201. The sleeve 201 is fixedly connected to the top of the fixing plate 1. A protection tube 202 is movably connected to the inner wall of the sleeve 201. The protection tube 202 is fixedly connected to the top of the fixing plate 1. A first spring 203 is fixedly connected to the bottom of the protection tube 202. The top of the first spring 203 is fixedly connected to a movable tube 204. A sliding block 205 is fixedly connected to the inner wall of the movable tube 204. A limiting groove 206 is formed on the side surface of the protection tube 202. The sliding block 205 is slidably connected to the inner wall of the limiting groove 206. By installing the protection component 2, when the second spring 207 in the mattress is under pressure, part of the pressure can be shared by the first spring 203 in the protection tube 202. At the same time, when the first spring 203 deforms under pressure, the sliding block 205 in the movable tube 204 will move in the limiting groove 206, thereby increasing the friction during movement, further reducing the pressure on the first spring 203 and the second spring 207, so that it can maintain its service life even under greater pressure. At the same time, by using the movable tube 204 and the anti - puncture tube 4 at the top, it can also prevent the first spring 203 from puncturing the mattress during use, thereby increasing the safety performance of the first spring 203.

[0020] In this embodiment, as Figure 2 and Figure 3 shown, a second spring 207 is fixedly connected to the top of the sleeve 201. The other end of the second spring 207 is fixedly connected to a connector 208. The connector 208 is fixedly connected to the bottom of the movable tube 204.

[0021] In this embodiment, as Figure 4 shown, a fixing component 3 is arranged on one side of the fixing plate 1. The fixing component 3 includes a fixing block 301. The fixing block 301 is fixedly connected to one side of the fixing plate 1. A connecting plate 302 is fixedly connected to one side of the fixing block 301. A fixing ring 303 is fixedly connected to one side of the connecting plate 302. A fixing spring 304 is movably connected to the inner wall of the fixing ring 303. The fixing spring 304 is fixedly connected to one side of the connecting plate 302. The other end of the fixing spring 304 is fixedly connected to a fixing strip 305. By installing the fixing component 3, pressure can be applied to the fixing springs 304 on both sides of the connecting plate 302 first to make them deform, and then the fixing block 301 and the connecting plate 302 are pushed into the connection port 306. When the fixing strip 305 on one side of the fixing spring 304 enters the bottom of the connection port 306, the fixing spring 304 will restore its deformation, thereby pushing the fixing strip 305 into the fixing groove 307, so that multiple fixing plates 1 can be connected together, thus better achieving series connection and improving the connection strength between the first spring 203 and the second spring 207.

[0022] In this embodiment, as Figure 5 shown, on the other side of the fixing plate 1, a connection port 306 is provided, and a fixing groove 307 is provided inside the connection port 306.

[0023] In this embodiment, as Figure 1 shown, a pipe protection tube 4 is fixedly connected to the top of the movable tube 204, and a felt cloth 5 is fixedly connected to the top of the pipe protection tube 4. By installing the pipe protection tube 4, it is possible to prevent the first spring 203 from piercing the mattress, thereby improving safety.

[0024] The usage method and advantages of the present utility model: When in use, the working process of this high-safety open spring is as follows:

[0025] As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, when in use, when the second spring 207 inside the mattress is under pressure, part of the pressure can be shared by the first spring 203 inside the protection tube 202. At the same time, when the first spring 203 deforms under pressure, the sliding block 205 inside the movable tube 204 will move in the limit groove 206, thereby increasing the friction during movement, and further reducing the pressure on the first spring 203 and the second spring 207. Thus, it can maintain its service life even under greater pressure. At the same time, by using the movable tube 204 and the pipe protection tube 4 at the top, it is also possible to prevent the first spring 203 from piercing the mattress during use, thereby increasing the safety performance of the first spring 203. At the same time, pressure is applied to the fixing springs 304 on both sides of the connecting plate 302 to deform them, and then the fixing block 301 and the connecting plate 302 are pushed into the connection port 306. When the fixing strip 305 on one side of the fixing spring 304 reaches the bottom of the connection port 306, the fixing spring 304 will return to its original shape, thereby pushing the fixing strip 305 into the fixing groove 307, so that multiple fixing plates 1 can be connected together, thus better achieving series connection and improving the connection strength between the first spring 203 and the second spring 207.
