Description

Technical Field

[0001] This application relates to the technical field of helical lines, and more specifically, to a helical line with anti-loosening joint contacts. Background Art

[0002] A helical line is a structure with a special geometric shape and is widely used in various fields. In mechanical engineering, helical lines are commonly used in components such as springs and threaded connectors; in electrical engineering, helical lines can be used as the structural forms of cables and coils; in the medical field, some medical devices also use helical line structures. With the continuous development of technology, the performance requirements for helical lines are getting higher and higher, and they need to maintain a stable shape and performance in complex working environments.

[0003] In actual use, helical lines may be affected by various external forces. For example, in some mechanical transmission systems, helical lines may bear large tensile or compressive forces. If the tensile force exceeds the yield strength of its material, the helical line will undergo plastic deformation and bend. Similarly, excessive compression may also cause the helical line to lose its original shape and bend. After bending, the helical line is prone to stress concentration during the force application process, thereby reducing its fatigue life. During long-term use, the helical line may break at the bent part. Summary of the Utility Model

[0004] To solve the above problems, this application provides a helical line with anti-loosening joint contacts.

[0005] The helical line with anti-loosening joint contacts provided by this application adopts the following technical solutions:

[0006] A helical line with anti-loosening joint contacts includes a helical line body. At one end of the helical line body, there are connection heads. At one end of each of the two connection heads, there are connection contacts, and an anti-bending component is arranged on the outer wall of the connection contacts.

[0007] There are two groups of anti-bending components. Each group of anti-bending components includes a protective shell, which is used to prevent the helical line body from bending. The number of protective shells is set to two. At one end of each of the two protective shells, there is a fixedly connected L-shaped rod, and at one end of each of the two L-shaped rods, there is a semi-circular ring connected.

[0008] Through the above technical solutions, the setting of the anti-bending component effectively prevents the bending of the helical line, ensures the stability of the connection, and the connection contacts will not be subjected to additional stress due to the bending of the helical line, thereby reducing the occurrence probability of problems such as poor contact and signal interruption, and also reducing the probability of helical line fracture.

[0009] Furthermore, at both ends of each semi-circular ring, there are connecting plates. Inside each two connecting plates, there are threaded holes, and a fixing bolt is threadedly connected inside each threaded hole.

[0010] Through the above technical solution, the threaded connection method of the fixing bolt makes the connection firm and facilitates installation and disassembly, and the state of the semi-circular ring can be adjusted at any time according to needs.

[0011] Furthermore, a placement rack is provided at one end of each L-shaped rod, and a negative pressure suction cup is provided inside the placement rack.

[0012] Through the above technical solution, the negative pressure suction cups are located on both sides of the connection contacts. The negative pressure suction cups adsorb on the surface of the external device by generating negative pressure, avoiding the loosening of the connection contacts when being pulled by external forces.

[0013] Furthermore, clamping blocks are provided at both ends of two of the protective cases, and slots are opened at one end of the other two protective cases. Each clamping block is respectively inserted into the corresponding slot.

[0014] Through the above technical solution, during installation, the clamping block on one protective case is inserted into the slot of the other protective case to realize the connection of the two protective cases.

[0015] Furthermore, the cross-section of each protective case is semi-circular, and two connected protective cases together form a protection cavity.

[0016] Through the above technical solution, the circular protection cavity wraps the spiral wire body therein. Such a design can provide protection for the spiral wire from all directions, preventing it from being bent by external forces.

[0017] Furthermore, two negative pressure suction cups are respectively located on both sides of the corresponding connection contacts. Each protective case is arranged on the outside of the spiral wire body and is in contact with the spiral wire body.

[0018] Furthermore, each semi-circular ring is in sliding fit with the connection head.

[0019] Furthermore, both clamping blocks are made of rubber material.

[0020] Through the above technical solution, since the clamping blocks are made of rubber material and have a certain elasticity, they can generate a certain frictional force after being inserted into the slots, so that the two protective cases are tightly connected together.

[0021] In summary, the present application includes at least the following beneficial technical effects:

[0022] (1) Through the setting of the anti-bending component in the present utility model, the bending of the spiral wire is effectively prevented, ensuring the stability of the connection. The connection contacts will not be subjected to additional stress due to the bending of the spiral wire, thereby reducing the occurrence probability of problems such as poor contact and signal interruption, and also reducing the probability of the spiral wire breaking;

[0023] (2) Through the fixed connection of the semi-circular ring, the adsorption of the negative pressure suction cup, and the auxiliary fixation of the clamping block, the combined effect of multiple measures greatly enhances the stability of the connection between the connection contact and the external device, reduces the situation of connection loosening or disconnection caused by external forces, vibrations and other factors, and ensures the stable transmission of signals or currents.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application; obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0030] Refer to Figures 1-4 , a spiral wire for preventing loosening of joint contacts, including a spiral wire body 1. Connection heads 2 are provided at one end of the spiral wire body 1, connection contacts 3 are provided at one end of the two connection heads 2, and an anti-bending component is provided on the outer wall of the connection contact 3;

[0031] There are two groups of anti-bending components. Each group of anti-bending components includes a protective shell 4. The protective shell 4 is used to prevent the spiral wire body 1 from being bent. The number of the protective shells 4 is set to two. L-shaped rods 5 are fixedly connected to one end of the two protective shells 4, and semi-circular rings 6 are connected to one end of the two L-shaped rods 5.

[0032] As the main anti-bending component, the protective shell 4 is directly wrapped around the outside of the spiral wire body 1 near the connection contact 3. When the spiral wire body 1 is subjected to an external force and has a tendency to be bent, the protective shell 4 provides rigid support and prevents the spiral wire body 1 from bending in this area.

[0033] The two semi-circular rings 6 can fit tightly when connected to form a complete circular ring structure, further enhancing the protection of the helix near the connection contact 3. When the helix is subjected to external forces from all directions, the semi-circular rings 6 can provide uniform supporting forces from the outside to prevent the helix from being bent.

[0034] Through the setting of the anti-bending component, the bending of the helix is effectively prevented, ensuring the stability of the connection. The connection contact 3 will not be subjected to additional stress due to the bending of the helix, thereby reducing the occurrence probability of problems such as poor contact and signal interruption. In electrical connections, a stable connection can ensure the stable transmission of current or signals and improve the reliability and performance of the device.

[0035] Refer to Figures 2-4 , both ends of each semi-circular ring 6 are provided with connecting plates 7, threaded holes are provided inside every two connecting plates 7, fixing bolts 8 are threadedly connected inside each threaded hole, one end of each L-shaped rod 5 is provided with a placement rack 10, a negative pressure suction cup 11 is provided inside the placement rack 10, and every two negative pressure suction cups 11 are respectively located on both sides of the corresponding connection contact 3. Each protective shell 4 is arranged on the outside of the helix body 1 and is in contact with the helix body 1. Each semi-circular ring 6 is slidably matched with the connection head 2.

[0036] Both ends of each semi-circular ring 6 are provided with connecting plates 7. When the two semi-circular rings 6 are butted, they are connected and fixed through the threaded holes and fixing bolts 8 on the connecting plates 7. In this way, it can be ensured that the two semi-circular rings 6 are closely combined to form a complete circular ring structure around the connection contact 3, providing stable support and protection for the helix and preventing it from being bent.

[0037] The threaded connection method of the fixing bolt 8 makes the connection firm and convenient for installation and disassembly, and the state of the semi-circular ring 6 can be adjusted at any time as needed.

[0038] A negative pressure suction cup 11 is provided inside the placement rack 10 at one end of the L-shaped rod 5. The negative pressure suction cups 11 are located on both sides of the connection contact 3. The negative pressure suction cups 11 adsorb on the surface of the external device by generating negative pressure, avoiding the loosening of the connection contact 3 when being pulled by external forces.

[0039] Through the fixed connection of the semi-circular rings 6, the adsorption of the negative pressure suction cups 11, and the auxiliary fixation of the clamping blocks 9, multiple measures work together, greatly enhancing the stability of the connection between the connection contact 3 and the external device, reducing the loosening or disconnection of the connection caused by factors such as external forces and vibrations, and ensuring the stable transmission of signals or currents.

[0040] Refer to Figures 2-4, where clamping blocks 9 are provided at both ends of two of the protective cases 4, and slots 12 are formed at one end of the other two protective cases 4. Each clamping block 9 is respectively inserted into the corresponding slot 12. The cross-section of each protective case 4 is semi-circular. Every two protective cases 4 are connected to jointly form a protective cavity. Both clamping blocks 9 are made of rubber material.

[0041] Clamping blocks 9 and slots 12 are respectively provided at both ends of the two protective cases 4. During installation, the clamping block 9 on one protective case 4 is inserted into the slot 12 of the other protective case 4 to realize the connection of the two protective cases 4. Since the clamping block 9 is made of rubber material and has a certain elasticity, it can generate a certain frictional force after being inserted into the slot 12, so that the two protective cases 4 are tightly connected together.

[0042] The cross-section of the protective case 4 is semi-circular. When the two protective cases 4 are connected, they jointly form a complete circular protective cavity, and the spiral wire body 1 is wrapped therein. Such a design can provide protection for the spiral wire from all directions and prevent it from being bent by external forces.

[0043] Through the connection method of the clamping block 9 and the slot 12, the two protective cases 4 can be tightly combined together to form a firm protective structure. This connection method is simple and reliable, can effectively prevent the protective cases 4 from separating during use, and ensure the continuous protection of the spiral wire body 1.

[0044] Working principle: An anti-bending component is provided on the outer wall of the connection contact 3. The anti-bending component includes two protective cases 4, which are wrapped around the spiral wire body 1 near the connection contact 3. When the spiral wire body 1 has a tendency to be bent by an external force, the protective case 4 provides rigid support. The L-shaped rod 5 at one end of the protective case 4 is connected to the semi-circular ring 6. The two semi-circular rings 6 are connected and fixed through the threaded holes and fixing bolts 8 on the connecting plate 7 to form a complete ring structure around the connection contact 3 to provide uniform supporting force for the spiral wire to prevent bending. The negative pressure suction cups 11 in the placing racks 10 at one end of the L-shaped rod 5 are located on both sides of the connection contact 3 and adsorb on the surface of the external device to prevent the connection contact 3 from being loosened by external pulling force. At the same time, the clamping blocks 9 at both ends of some of the protective cases 4 are inserted into the slots 12 of some other protective cases 4 to realize the connection. The clamping blocks 9 are made of rubber material and have elasticity to generate frictional force to tightly connect the protective cases 4, jointly forming a circular protective cavity to wrap the spiral wire body 1, protecting the spiral wire from bending from all directions. Through the multiple functions of the protective case 4, the semi-circular ring 6, the negative pressure suction cup 11 and the clamping block 9, the spiral wire is effectively prevented from being bent, the connection stability is ensured, the occurrence probability of poor contact and signal interruption is reduced, the stable transmission of current or signal is guaranteed, and the reliability and performance of the device are improved.

[0045] The above are all preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
