A water pipe with a self-tightening device

Abstract

This utility model relates to a water pipe with a self-tightening device, belonging to the field of water pipe technology. It includes a connecting assembly with two locking components on its outer surface to improve the connection effect. Water pipes are threaded to both sides of the connecting assembly, and the connecting assembly communicates with both water pipes. The two locking components extend to the outer surfaces of the two water pipes respectively. During installation, the connecting assembly is first rotated to ensure a tight connection between it and the water pipes. Simultaneously, rotating the connecting assembly transmits power to the locking components, causing them to rotate. Once the connection is stable, the transmission ring is rotated further, and then the two transmission pins are pressed while simultaneously pulling the transmission ring away from the connecting assembly. This creates a continuous self-tightening force between the water pipes and the connecting assembly. The water pipe uses a threaded connection, and the locking components eliminate the problem of loosening in threaded connections.

Description

Technical Field

[0001] This utility model relates to the field of water pipe technology, specifically a water pipe with a self-tightening device. Background Technology

[0002] Water pipes are pipelines used to transport liquids. They are key components in many engineering systems such as water supply and drainage systems and heating and ventilation systems. Their quality and performance directly affect the efficiency and safety of liquid transportation. With the development of society, the water pipe industry is also constantly evolving.

[0003] For example, Chinese Patent (Publication No.: CN219493347U) discloses a water pipe, including a flexible hose and a sheath made of braided threads. The sheath is fitted around the outer circumference of the flexible hose. When the flexible hose expands, the diameter of the sheath is P millimeters. The cross-section of the sheath has N braided threads, and the range of N is 2.58P≤N≤10P. The water pipe provided by this application ensures the density of braided threads per unit length in the circumferential direction of the sheath by satisfying the relationship 2.58P≤N≤10P between the number of braided threads on the cross-section of the sheath and the diameter of the sheath with the flexible hose expanded to P millimeters. This makes it less likely to be punctured by sharp objects, thereby improving wear resistance and puncture resistance, and effectively extending the service life of the water pipe.

[0004] However, the stability of the water pipe connection is not high enough. After a long period of use, the connection is prone to loosening, resulting in an unstable overall connection of the water pipe, which affects the normal use of the water pipe. Therefore, a water pipe with a self-tightening device is proposed to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a water pipe with a self-tightening device, which has the advantages of high connection stability and solves the problem of water pipe connections easily loosening after long-term use.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a water pipe with a self-tightening device, comprising a connecting assembly, wherein the outer surface of the connecting assembly is provided with two locking components that can improve the connection effect, and water pipes are threadedly connected to both sides of the connecting assembly, the connecting assembly is connected to both water pipes, and the two locking components extend to the outer surfaces of the two water pipes respectively.

[0007] Each of the locking components includes an extension tube fixed to the outer surface of the connecting component, the extension tube extending to the outside of the water pipe, and a torsion spring fixed to the inner side of each extension tube located outside the water pipe, the torsion spring being movably connected to the water pipe. A transmission ring movably connected to the water pipe is fixed to the side of the torsion spring away from the extension tube. Two transmission pins extending outside the extension tube are movably connected to the side of the extension tube away from the connecting component, both of the transmission pins penetrating the transmission ring. Each transmission pin has a limiting portion penetrating the transmission pin on the inner side of the transmission ring.

[0008] Furthermore, each of the connecting components consists of a connecting pipe, two retaining rings, and two sleeves. The left and right sides of the connecting pipe are respectively fixed to the two retaining rings. The two sleeves are rotatably connected to the connecting pipe through the two retaining rings. The opposite sides of the two sleeves are respectively threaded to two water pipes.

[0009] Furthermore, both of the aforementioned sleeves are connected to the connecting pipe, and the opposite sides of the two sleeves are respectively connected to two water pipes.

[0010] Furthermore, a sealed bearing is fixed to the inner side of each of the stabilizing rings, and each of the stabilizing rings is rotatably connected to the sleeve pipe through the sealed bearing.

[0011] Furthermore, each of the two extension tubes has a positioning groove on the opposite side located outside the water pipe, and each of the drive pins extends into the extension tube through the positioning groove.

[0012] Furthermore, each of the water pipes has multiple stabilizing keys fixed on its outer surface, and each of the transmission rings has multiple stabilizing grooves on the side near the stabilizing key. The multiple stabilizing keys are respectively adapted to and movably connected to the multiple stabilizing grooves.

[0013] Furthermore, each of the transmission pins is provided with a limiting hole that penetrates the transmission pin, and each of the transmission pins is provided with two limiting grooves located on the left and right sides of the limiting hole.

[0014] Furthermore, each of the limiting parts includes two movable rods that are movably connected to the limiting hole and extend out of the transmission pin. A connecting plate is fixed on the opposite side of each of the two movable rods. Limiting plates extending into the limiting groove are fixed on both the left and right sides of each connecting plate. A compression spring is fixed on the opposite side of each of the two connecting plates.

[0015] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0016] During installation, the water pipe with a self-tightening device is first rotated to ensure a tight connection between the connecting component and the water pipe. Simultaneously, as the connecting component is rotated, power is transmitted to the locking component, causing it to rotate. Once the connecting component is stably connected, the transmission ring is rotated again. Then, the two transmission pins are pressed down, and the transmission ring is pulled away from the connecting component, thus creating a continuous self-tightening force between the water pipe and the connecting component.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 In this embodiment, a water pipe with a self-tightening device includes a connecting component 1. The outer surface of the connecting component 1 is provided with two locking components 2 that can improve the connection effect. The locking components 2 can play a connecting role and achieve continuous self-tightening by cooperating with the water pipe 3 through their own elasticity. The left and right sides of the connecting component 1 are threaded with water pipes 3. The connecting component 1 is connected to both water pipes 3. The two locking components 2 extend to the outer surface of the two water pipes 3 respectively.

[0023] It should be further explained that each connecting component 1 consists of a connecting pipe 101, two retaining rings 102, and two sleeves 103. The cross-section of the retaining ring 102 is T-shaped. This shape can ensure the stable connection between the connecting pipe 101 and the two sleeves 103, while ensuring that the two sleeves 103 can rotate freely. The left and right sides of the connecting pipe 101 are fixed to the two retaining rings 102 respectively. The two sleeves 103 are rotatably connected to the connecting pipe 101 through the two retaining rings 102. The opposite sides of the two sleeves 103 are threadedly connected to the two water pipes 3 respectively. The threaded connection has good connection stability.

[0024] In addition, both sleeves 103 are connected to the connecting pipe 101. The connection between the sleeves 103 and the connecting pipe 101 ensures that the water in the water pipe 3 flows smoothly. The opposite sides of the two sleeves 103 are connected to the two water pipes 3 respectively. Each stabilizing ring 102 has a sealed bearing fixed inside. Each stabilizing ring 102 is rotatably connected to the sleeve 103 through the sealed bearing.

[0025] In this embodiment, the threaded connection has good stability. This connection method is relatively strong, but the installation process is relatively complicated and requires certain tools and techniques. Furthermore, during long-term use, water leakage may occur due to loosening of the threads. By using the locking component 2, this problem can be effectively improved, thereby enhancing the overall precision and stability.

[0026] Please refer to it again. Figure 1 and Figures 2 to 3 To improve the stability of the connection, each locking assembly 2 in this embodiment includes an extension tube 201 fixed to the outer surface of the connecting assembly 1. The extension tube 201 extends to the outside of the water pipe 3. A torsion spring 203 located outside the water pipe 3 is fixed to the inner side of each extension tube 201. The torsion spring 203 can transmit force and has a certain deformation capacity. The torsion spring 203 is movably connected to the water pipe 3. A transmission mechanism movably connected to the water pipe 3 is fixed to the side of the torsion spring 203 away from the extension tube 201. When the transmission ring 204 rotates, it can transmit force to the torsion spring 203, and then to the extension cylinder 201 through the torsion spring 203, thereby achieving a continuous self-tightening effect. Two transmission pins 202 extending out of the extension cylinder 201 are movably connected to the side of the extension cylinder 201 away from the connecting component 1. Both transmission pins 202 pass through the transmission ring 204. Each transmission pin 202 and the inner side of the transmission ring 204 is provided with a limiting part 205 that passes through the transmission pin 202. The transmission pin 202 plays a role in abutment.

[0027] It is known that each of the two extension tubes 201 has a positioning groove on the opposite side of the water pipe 3. The positioning groove is annular and allows the transmission pin 202 to move inside. Since the transmission pin 202 will rotate when the transmission ring 204 is rotated, the positioning groove is required to ensure that it can be properly engaged later. Each transmission pin 202 extends into the extension tube 201 through the positioning groove. Multiple stabilizing keys are fixed on the outer surface of each water pipe 3. Multiple stabilizing grooves are opened on the side of each transmission ring 204 near the stabilizing key. The multiple stabilizing keys are adapted to and movably connected to the multiple stabilizing grooves. When the transmission ring 204 moves to the outside of the stabilizing key, the stabilizing groove and the stabilizing key on its inner side cooperate to effectively fix the transmission ring 204.

[0028] In addition, each transmission pin 202 is provided with a limiting hole that passes through the transmission pin 202, and each transmission pin 202 is provided with two limiting grooves located on the left and right sides of the limiting hole. The limiting grooves are used to improve the stability of the limiting part 205. Each limiting part 205 includes two moving rods 2051 that are movably connected to the limiting hole and extend out of the transmission pin 202. A connecting plate 2052 is fixed on the opposite side of the two moving rods 2051. Limiting plates extending into the limiting grooves are fixed on the left and right sides of each connecting plate 2052. A compression spring 2053 is fixed on the opposite side of the two connecting plates 2052. When the two moving rods 2051 lose external force constraint, the compression spring 2053 can release elastic potential energy, causing the two moving rods 2051 to pop out quickly and achieve abutment.

[0029] In this embodiment, due to the stable fixation of the water pipe 3 to the transmission ring 204, the force is transmitted to the extension cylinder 201 through the torsion spring 203, and further transmitted to the connecting assembly 1, thereby causing the threaded connection to remain stable and self-tight.

[0030] It is understandable that the power is transmitted through the torsion spring 203, and the torsion spring 203 can undergo slight deformation, thereby ensuring the continuous stability of the self-tightening force. The sealing bearing and the retaining ring 102 cooperate to improve the overall sealing performance.

[0031] The working principle of the above embodiments is as follows:

[0032] During installation, first rotate the sleeve 103 on the connecting assembly 1 to ensure a tight connection between the sleeve 103 and the water pipe 3. When rotating the sleeve 103, its power is transmitted to the locking assembly 2, causing the extension tube 201 to rotate. Due to the action of the torsion spring 203, the transmission ring 204 will also rotate. After the connecting assembly 1 is connected stably, continue to rotate the transmission ring 204. Then, press down on the two transmission pins 202 and pull the transmission ring 204 away from the connecting assembly 1. At this time, the torsion spring 203 is stretched by the tensile force. When the limiting part 205 separates from the transmission ring 204, under the action of the compression spring 2053, the two moving rods 2051 will move outward at the same time, thereby achieving a locking effect. At this time, the stabilizing groove on the transmission ring 204 and the stabilizing key on the water pipe 3 cooperate with each other to successfully lock the transmission ring 204. The self-tightening force is transmitted to the connecting pipe 101 through the torsion spring 203 to achieve a continuous self-tightening effect.
