Description

Technical Field

[0001] This utility model relates to the field of springs, specifically to an anti-tensile spring structure. Background Technology

[0002] Traditional spring structures are prone to deformation and breakage under prolonged tensile use, especially under high loads, where the spring's tensile strength becomes paramount. Currently, most springs rely on the high strength of the material to resist tension. While this material strength provides some resistance, the cylindrical helical structure of most tension springs makes their tensile strength susceptible to interference from external connectors, hindering control. Consequently, excessive tensile strength or reaching the spring's maximum compression can easily lead to deformation or even breakage of the spring coil, increasing the risk of damage, reducing stability during use, and shortening the spring's lifespan. Utility Model Content

[0003] The purpose of this utility model is to provide an anti-tension spring structure. This anti-tension spring structure is convenient to connect and can effectively reduce the probability of the spring body being in a state of extreme tension or compression due to the influence of external connecting parts. It can also effectively reduce the phenomenon of deformation or even breakage of the spring coil under extreme tension or compression, reduce the probability of spring damage, further improve the structural stability and function of this anti-tension spring structure, and appropriately extend its service life.

[0004] The technical solution adopted by this utility model to solve the above problems is:

[0005] A tensile spring structure includes a spring body, the spring body comprising an inner spring and an outer spring formed by spirally winding spring wire, and a U-shaped connecting part formed by connecting the two ends of the inner spring and the outer spring. A connecting plate is provided on the connecting part, and a tensile component is provided between the two sets of connecting plates. The tensile component includes a first connecting rod passing through the inner spring and connected to the two sets of connecting plates respectively, and a second connecting rod slidingly disposed on the first connecting rod. The first connecting rod, the second connecting rod, and the connecting plate are all provided with through grooves.

[0006] Preferably, the connecting plate is detachably mounted on the connecting part through slots provided at both ends, and the first connecting rod and the second connecting rod are detachably connected to the two sets of connecting plates respectively.

[0007] Preferably, the second connecting rod is rotatably provided with a top cover for detachable connection to the first connecting rod.

[0008] Preferably, the spring body further includes a telescopic sleeve placed between the two sets of connecting plates and sleeved around the outer spring. The two ends of the telescopic sleeve are detachably connected through slots provided on the connecting plates, and multiple sets of rotatably configured locking elements are provided on the connecting plates surrounding the slots.

[0009] Preferably, a raised ring is provided on the corresponding wall surface of the connecting plate away from the tensile component around the through groove.

[0010] Compared with the prior art, this utility model has the following advantages and effects:

[0011] This utility model relates to a tensile spring structure. Compared to traditional spring structures, this tensile spring structure features an integrated design with a double-spring structure (inner and outer springs formed by spirally winding spring wire) and a U-shaped connecting part at both ends. This facilitates connection and further enhances the structural stability and tensile strength of the spring body. Furthermore, the addition of a tensile component connecting the inner spring to the connecting plates at both ends allows for synchronous expansion and contraction along the spring body, without affecting its normal expansion and contraction. This is further enhanced by the first connecting rod in the tensile component. The length setting of the second connecting rod and the corresponding telescopic length structural setting can ensure that the maximum tensile length of the spring body does not exceed its ultimate tensile length, and the minimum compression length is not less than its ultimate compression length. This ensures that the spring body can perform stable telescopic movement. Compared with traditional spring structures, it can effectively reduce the probability of the spring body being in an ultimate tensile or compression state due to the influence of external connecting parts, and effectively reduce the phenomenon of deformation or even breakage of the spring coil under ultimate tensile or compression state. This reduces the probability of spring damage, further improves the structural stability and effect of this anti-tension spring structure, and appropriately extends its service life.

Detailed Implementation

[0016] The present invention will now be described in detail with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0017] See Figure 1-3 This embodiment relates to a tensile spring structure, including a spring body 1. The spring body 1 includes an inner spring 11 and an outer spring 12 formed by spirally winding spring wire, and a U-shaped connecting part 13 formed by connecting the two ends of the inner spring 11 and the outer spring 12. A connecting plate 2 is provided on the connecting part 13, and a tensile component 3 is provided between the two sets of connecting plates 2. The tensile component 3 includes a first connecting rod 31 that passes through the inner spring 11 and is connected to the two sets of connecting plates 2 respectively, and a second connecting rod 32 that slides on the first connecting rod 31. A through groove 100 is provided on the first connecting rod 31, the second connecting rod 32, and the connecting plate 2.

[0018] Specifically in this embodiment, such as Figure 1 The overall structural design of this type of tensile spring structure shown is combined with... Figure 2 and Figure 3 As shown, the spring body 1 can be manufactured in the early stages of production. Figure 3For example, the spiral winding of the spring wire forms a double-spring structure of inner spring 11 and outer spring 12. Simultaneously, the end of the wound spring wire can align with its initial end, forming connecting portions 13 at both ends of the inner spring 11 and outer spring 12. The ends of the spring wire and the initial end are combined using argon arc welding or other connection methods to ensure a stable connection and form an integral structure of the spring body 1. Then, according to the structural arrangement of the connecting portion 13, connecting plates 2 are installed. During installation, the first connecting rod 31 and the second connecting rod 32 on the two sets of connecting plates 2 can pass through the inner spring 11 and slide within it. The connecting plates 2 located on the connecting portion 13 can block both ends of the inner spring 11 and outer spring 12, and can be fixed to the connecting portion 13 using argon arc welding or other connection methods after the position adjustment is completed, according to usage requirements. The first connecting... The extension and retraction lengths of the connecting rod 31 and the second connecting rod 32 can be set according to the structure and elastic strength of the spring body 1. The maximum extension and retraction length does not exceed the maximum extension length of the spring body 1 under the ultimate tension state. Similarly, the minimum extension and retraction length is not less than the minimum compression length of the spring body 1 under the ultimate compression state. In actual use, this spring body 1 can be connected to the external connecting parts through the U-shaped connecting parts 13 provided at both ends. The spring body 1 can extend and retract through the double spring structure of the inner spring 11 and the outer spring 12. At the same time, the first connecting rod 31 and the second connecting rod 32, which are respectively connected to the two sets of connecting plates 2 in the anti-tension component 3 inside the inner spring 11, can perform synchronous extension and retraction processes with the spring body 1 in the corresponding length. In addition, combined with the through grooves 100 opened at the corresponding positions of the first connecting rod 31, the second connecting rod 32, and the connecting plate 2, the normal extension and retraction process of the anti-tension component 3 can be ensured.Compared to traditional spring structures, this type of tensile spring structure features a unique integrated design. The spring body 1 has a double-spring structure consisting of an inner spring 11 and an outer spring 12 formed by the spiral winding of spring wire, along with a U-shaped connecting portion 13 connecting the two ends of the inner and outer springs 11 and 12. This design facilitates connection and further enhances the structural stability and tensile strength of the spring body 1. Furthermore, the addition of a tensile-resistant component 3, which connects the inner spring 11 to the connecting plates 2 at both ends, allows for synchronous extension and retraction along with the spring body 1, without affecting its normal expansion and contraction. This is further enhanced by the first connecting rod 31 within the tensile-resistant component 3. The length setting of the second connecting rod 32 and the corresponding extension length structural setting can ensure that the maximum extension length of the spring body 1 does not exceed the extension length under its ultimate extension state, and the minimum compression length is not less than the compression length under its ultimate compression state. This ensures that the spring body 1 can perform stable extension and contraction. Compared with traditional spring structures, it can effectively reduce the probability of the spring body 1 being in an ultimate extension or compression state due to the influence of external connecting parts, and effectively reduce the phenomenon of deformation or even breakage of the spring coil under the ultimate extension or compression state, reduce the probability of spring damage, further improve the structural stability and effect of this anti-tension spring structure, and appropriately extend its service life.

[0019] The connecting plate 2 is detachably mounted on the connecting part 13 via slots 21 at both ends. The first connecting rod 31 and the second connecting rod 32 are detachably connected to the two sets of connecting plates 2, respectively. Figure 2 and Figure 3 The position settings, structural settings, and connection methods of the slots 21 at both ends of the connecting plate 2 corresponding to the structure of the connecting part 13 are shown, along with the combination of... Figure 4 and Figure 5 As shown, the first connecting rod 31 and the second connecting rod 32 can be detachably connected by rotating through the threaded holes 22 opened at corresponding positions on the two sets of connecting plates 2. During installation, the tensile component 3 can be pre-placed inside the inner spring 11. The two sets of connecting plates 2 can be tilted at a certain angle and connected to the U-shaped connecting parts 13 on both sides of the spring body 1 through the slots 21 opened on them. At the same time, the position of the connecting plates 2 can be adjusted by sliding left and right on the connecting parts 13, so that the first connecting rod 31 and the second connecting rod 32 can be connected by rotating relative to each other in the corresponding threaded holes 22 on the two sets of connecting plates 2. The connecting plates 2 and the tensile component 3 set by this connection method on the spring body 1 can further improve the detachability and disassembly flexibility of this tensile spring structure, meet different usage requirements, and improve applicability and practicality.

[0020] The second connecting rod 32 is rotatably provided with a top cover 33 for detachable connection to the first connecting rod 31, such as... Figure 4 and Figure 5 The top cover 33 shown is designed to be detachably connected by rotating through a second threaded hole 321 at one end of the second connecting rod 32. This facilitates the disassembly and separation of the first connecting rod 31 and the second connecting rod 32. At the same time, the top cover 33 can limit the maximum extension length between the first connecting rod 31 and the second connecting rod 32 during installation, further improving the structural detachability and disassembly flexibility of the tensile component 3, and facilitating daily inspection and subsequent maintenance.

[0021] The spring body 1 also includes a telescopic sleeve 34 placed between two sets of connecting plates 2 and sleeved around the outer spring 12. The two ends of the telescopic sleeve 34 are detachably connected via slots 23 provided on the connecting plates 2, and multiple sets of rotatably mounted locking elements 24 are provided around the connecting plates 23. Specifically... Figure 3 As can be seen, the telescopic sleeve 34 can be structurally set to a corresponding length according to the specifications of the spring body 1 and the corresponding tensile length. At the same time, its two ends can be inserted into the slots 23 opened at the corresponding positions on the connecting plate 2 for an appropriate length. Then, by rotating the multiple sets of locking parts 24 set at the corresponding positions on the connecting plate 2, the telescopic sleeve 34 in the slots 23 can be locked, so that the telescopic sleeve 34 can synchronously extend and retract with the spring body 1. The addition of the telescopic sleeve 34 can provide a certain protective effect for the spring body 1. At the same time, the detachable connection with the connecting plate 2 facilitates disassembly, replacement, and cleaning. In addition, by rotating a set of locking parts 24 on the connecting plate 2, the telescopic sleeve 34 can be extended and retracted at the other end, which facilitates the inspection of the internal outer spring 12, inner spring 11, and anti-tension component 3. This further improves the disassembly convenience, usage flexibility, and applicability of this anti-tension spring structure.

[0022] A protruding ring 25 is also provided on the corresponding wall surface of the connecting plate 2 away from the tensile component 3 around the through groove 100. The setting of the protruding ring 25 can further improve the structural strength of the connecting plate 2. At the same time, the diameter of the protruding ring 25 can be adapted to the specific structure of the connector, which can play a certain role in resisting the external connector. It can also reduce the phenomenon that the through groove 100 is blocked due to the resistance of the connector, which affects the normal expansion and contraction process of the tensile component 3. In addition, the corresponding wall surface of the connecting plate 2 with the protruding ring 25 can also be adapted to the structure of the connector. With the connection part 13, the flexibility and applicability of this tensile spring structure can be further improved.

[0023] The above description in this specification is merely illustrative of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined in the claims, all of which shall fall within the protection scope of this invention.
