Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mattress supporting spring structures, in particular to a spring with a multi-layer buffer structure. Background Art
[0002] Nowadays, in order to pursue better support and comfort, many mattresses usually have springs installed inside the mattress. The springs play a role of buffering and support, thereby improving the comfort and support of the mattress.
[0003] In order to meet the requirements of different groups of people for softness, hardness and comfort, many mattresses are now designed by changing the diameter of the spring to adjust the elastic coefficient of the spring, and through multiple independent spring bags, the springs are independent of each other to avoid mutual influence during use. However, in actual use, when the spring body is designed to be thin, the elasticity is greater and the support is poor. When the spring contacts the user, the deformation at both ends is large, which makes the depression serious when supporting a small area, and the contact surface has a poor touch. More flexible layers are needed to isolate it. At the same time, the overall compression of the spring is greater. When encountering rapid extrusion impact, the spring is prone to side bending, damage and detachment from the installation position. For this reason, a spring with a multi-layer buffer structure is specially provided to solve the above problems. Utility Model Content
[0004] In view of the deficiencies in the prior art, the utility model provides a spring with a multi-layer buffer structure, which solves the problem that in actual use, when the design of the spring body is too thin, the elasticity is relatively large, the supporting performance is poor, and the deformation of the two ends of the spring is large when it contacts the user. This causes serious depression when supporting a small area, and the contact surface has a poor touch, requiring the use of more flexible layers for isolation. At the same time, the overall compression of the spring is greater, and when encountering rapid extrusion impact, the spring is prone to side bending, damage, and detachment from the installation position.
[0005] To achieve the above objectives, the utility model is implemented through the following technical solutions: A spring with a multi-layer buffer structure, including a main support memory spring, both ends of the main support memory spring are provided with conical elastic support contact pieces, and the conical elastic support contact pieces include;
[0006] Conical outward expansion springs, which are integrally formed at both ends of the main support memory spring;
[0007] A wave spring disposed inside the conical expansion spring;
[0008] A reverse tensile elastic guide is provided inside the main support memory spring, and the reverse tensile elastic guide comprises:
[0009] Guide columns, which are arranged inside both ends of the main support memory spring;
[0010] The two ends of the stretch memory spring are respectively fixedly installed on the ends opposite to the two sets of guide pillars.
[0011] Preferably, the diameter of the main support memory spring gradually decreases from the middle to both ends.
[0012] Preferably, the conical elastic supporting contact member further comprises:
[0013] Pads, which are fixedly arranged at both ends of the main support memory spring;
[0014] The conical sleeve bag is fixedly arranged on the top of the pad, and the conical sleeve bag is movably sleeved on the outer surface of the conical outward expansion spring.
[0015] Preferably, one end of the guide column is fixedly connected to the backing plate, and the other end of the guide column is fixedly connected to a positioning circular plate.
[0016] Preferably, two ends of the tension memory spring are respectively fixedly connected to opposite sides of two sets of positioning circular plates.
[0017] Preferably, the guide column passes through the positioning circular plate on the opposite side.
[0018] The utility model discloses a spring with a multi-layer buffer structure, which has the following beneficial effects: by installing conical elastic support contact pieces at both ends of a main support memory spring, the conical outward expansion spring is used to increase the end contact area, and a wave spring is arranged inside, and the high load capacity of the wave spring is used to make the end face have better contact support, and the touch is improved for complex force conditions, and a reverse stretching elastic guide piece is arranged inside the main support memory spring, and axial deformation positioning is achieved by using a guide column and a positioning circular plate, so that the main support memory spring is prevented from lateral bending when encountering a rapid impact, resulting in separation from the installation position.

[0026] The embodiment of the present application provides a spring with a multi-layer buffer structure, which solves the problem that when the spring body is designed to be thin, the elasticity is large and the supporting performance is poor. When the spring comes into contact with the user, the deformation at both ends is large, which causes severe depression when supporting a small area and the contact surface has a poor touch. More flexible layers are needed for isolation. At the same time, the overall compression of the spring is greater. When encountering rapid extrusion impact, the spring is prone to side bending, damage, and detachment from the installation position.
[0027] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0028] The utility model embodiment discloses a spring with a multi-layer buffer structure.
[0029] According to the attached Figure 1-4 As shown, it includes a main support memory spring 1, the diameter of which decreases gradually from the middle to both ends. When compressed, the front section has better elasticity and the rear section has higher support strength.

The conical outward-expanding spring 22 is integrally formed at both ends of the main support memory spring 1; the wave spring 23 is arranged inside the conical outward-expanding spring 22; the pad 21 is fixedly arranged at both ends of the main support memory spring 1; the conical sleeve 24 is fixedly arranged on the top of the pad 21, and the conical sleeve 24 is movably sleeved on the outer surface of the conical outward-expanding spring 22.
[0031] By installing conical elastic support contact pieces 2 at both ends of the main support memory spring 1, the conical outward expansion spring 22 is used to increase the end contact area. At the same time, a wave spring 23 is arranged inside. The high load capacity of the wave spring 23 is utilized to make the end face have better contact support, thereby improving the touch in response to complex force conditions.
[0032] A reverse stretching elastic guide 3 is arranged inside the main support memory spring 1, and the reverse stretching elastic guide 3 includes a positioning circular plate 31, a guide column 32 and a stretching memory spring 33. The guide column 32 is arranged inside the two ends of the main support memory spring 1; the two ends of the stretching memory spring 33 are respectively fixedly installed on the opposite ends of the two groups of guide columns 32, one end of the guide column 32 is fixedly connected to the pad 21, and the other end of the guide column 32 is fixedly connected to the positioning circular plate 31, and the two ends of the stretching memory spring 33 are respectively fixedly connected to the opposite sides of the two groups of positioning circular plates 31, and the guide column 32 passes through the positioning circular plate 31 on the opposite side.
[0033] A reverse stretching elastic guide 3 is arranged inside the main support memory spring 1, and axial deformation positioning is achieved by using a guide column 32 and a positioning circular plate 31 to prevent the main support memory spring 1 from bending sideways when encountering a rapid impact and causing it to be out of the installation position. At the same time, the stretching memory spring 33 is reversely stretched when the main support memory spring 1 is compressed, thereby providing more front-end elastic support force.
