Description

Technical Field

[0001] The utility model belongs to the technical field of construction engineering, in particular to a high-strength elbow for galvanized pipe splicing. Background Technique

[0002] In modern industrial and civil facilities, the construction pipeline system is widely used to transport various cables. To adapt to different layout requirements, elbows are usually used to change the direction of the pipeline. Although the traditional galvanized pipe fitting connection elbows can meet the basic connection requirements, there are some problems and deficiencies in actual applications.

[0003] When transporting cables, the inner corner area of the traditional elbow is prone to become a clogging point. These cables will pile up when passing through the elbow, gradually forming a blockage, affecting the normal passing of the cables. This not only reduces the operating efficiency of the system, but also increases the maintenance cost and may lead to serious equipment failures. Content of the Utility Model

[0004] The purpose of the utility model is to provide a high-strength elbow for galvanized pipe splicing to solve the problems raised in the background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A high-strength elbow for galvanized pipe splicing, comprising:

[0006] Two galvanized pipe fittings are arranged at the required angles.

[0007] An elbow pipe assembly is arranged at the angle between the two galvanized pipe fittings and includes a bent pipe fitting at the required angle. The two pipe ends of the bent pipe fitting are respectively sealed and sleeved with the opposite ends of the two galvanized pipe fittings.

[0008] Two fasteners are provided and are respectively fastened to the two ends of the bent pipe fitting, fastening the opposite ends of the two galvanized pipe fittings in the inner cavities at the two ends of the bent pipe fitting.

[0009] An anti-blocking vibration assembly is arranged in the inner cavity angle of the bent part of the bent pipe fitting and includes an elastic plastic arc-shaped integral cover integrally connected to the inner wall of the corner of the bent pipe fitting, a receiving cavity formed between the elastic plastic arc-shaped integral cover and the inner wall of the bent pipe fitting, and a vibration source component arranged in the receiving cavity. The vibration source component generates mechanical force to strike the inner wall of the elastic plastic arc-shaped integral cover, so that the elastic plastic arc-shaped integral cover generates elastic vibration force, preventing the cables passing through the bent pipe fitting from being blocked at the angle.

[0010] Preferably, the vibration source component includes a hand pull rod inserted into the receiving cavity from the outside of the bent part of the bent pipe fitting, an arc-shaped top plate fixed to the free end of the inserted hand pull rod, and a return spring sleeved on the inner end of the hand pull rod located in the receiving cavity.

[0011] Preferably, the reset spring is located between the arc-shaped top plate and the inner wall of the accommodating cavity, and both ends of the reset spring elastically abut against the arc-shaped top plate and the inner wall of the accommodating cavity respectively.

[0012] Preferably, in this solution, when the return spring is in a natural state, the curved outer wall of the arc-shaped top plate away from the hand rod abuts against the inner wall of the elastic plastic arc-shaped integrated cover plate, and when the hand rod is pulled, the arc-shaped top plate squeezes the return spring, so that the return spring accumulates force on the arc-shaped top plate.

[0013] Preferably, in this solution, the elastic plastic arc-shaped integrated cover plate is provided with an elastic vibration part on one side facing the arc-shaped top plate, and after the arc-shaped top plate accumulates force, the hand pull rod is released so that the arc-shaped top plate hits the elastic vibration part.

[0014] In the preferred embodiment of the present invention, the elastic vibration part is integrally connected with the elastic plastic arc-shaped integral cover plate, and the elastic plastic arc-shaped integral cover plate and the elastic vibration part are made of styrene-butadiene-styrene block copolymer.

[0015] Preferably, the inner walls at both ends of the bent pipe are provided with annular grooves, a silicone sealing ring is bonded in each of the annular grooves, and the inner wall of the silicone sealing ring is integrally provided with anti-slip protrusions, which are in elastic friction contact with the outer wall of the galvanized pipe fitting.

[0016] Preferably, each of the fasteners includes two clamp semicircular rings relatively clamped on the outer wall of the circumferential side of the bent pipe member and two mounting leg seats symmetrically welded to the outer wall of one of the clamp semicircular rings.

[0017] Preferably, both ends of the two clamp semicircular rings are fastened together by locking bolts, and a mounting hole is provided at the lower portion of the mounting leg seat.

[0018] Preferably, in the present solution, rubber protective washers are provided on the inner walls of the two semicircular rings of the clamps, and the rubber protective washers are sleeved on the outer wall of the circumference of the bent pipe piece.

[0019] Compared with the prior art, the technical effects and advantages of the utility model are as follows:

[0020] The high-strength elbow for galvanized pipe splicing has an anti-blocking vibration component set in the inner cavity angle of the elbow, which can effectively solve the problem of cable accumulation that is easy to occur inside the traditional elbow. By generating elastic vibration force, the component can vibrate the blocked cables to ensure smooth passage of the cables, reducing maintenance frequency and costs.

[0021] By using fasteners to firmly fix the galvanized pipe fittings in the inner cavities at both ends of the elbow pipe fittings, the mechanical strength at the pipe connection is enhanced. This helps prevent joint loosening or leakage caused by external stress. The two pipe end portions of the elbow pipe fittings are respectively sealed and sleeved with the opposite ends of the galvanized pipe fittings, and annular grooves are provided on the inner walls at both ends of the elbow pipe fittings, in which silica gel sealing rings are bonded. The anti-slip bumps on the silica gel sealing rings increase the friction with the outer wall of the galvanized pipe fittings, thus providing a better sealing effect and reducing the risk of fluid leakage.

Detailed Description of the Embodiments

[0030] In the following description, a large number of specific details are given to provide a more thorough understanding of the present utility model. However, it is obvious to those skilled in the art that the present utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present utility model, some technical features well-known in the art are not described.

[0031] Unless otherwise defined, the directions such as up, down, left, right, front, back, inner and outer involved in this article are based on the up, down, left, right, front, back, inner and outer directions in the figures shown in the present utility model, which are hereby explained together.

[0032] This embodiment provides a high-strength elbow for splicing galvanized pipes as shown in Figures 1 to 5 Figure, which includes: a galvanized pipe fitting 1, an elbow pipe assembly 2, a fastener 4, and an anti-blocking vibration assembly 20.

[0033] In this embodiment, two galvanized pipe fittings 1 are arranged at a required included angle.

[0034] In this embodiment, the elbow pipe assembly 2 is arranged at the included angle between the two galvanized pipe fittings 1 and includes a bent pipe fitting 3 at a required included angle. The two pipe ends of the bent pipe fitting 3 are respectively and sealingly sleeved with the opposite ends of the two galvanized pipe fittings 1; the elbow pipe assembly 2 includes a bent pipe fitting 3 for changing the threading direction of the cable and connecting two straight galvanized pipe fittings 1 at a certain angle.

[0035] In this embodiment, two fasteners 4 are provided and are respectively fastened to both ends of the bent pipe fitting 3 to fasten the opposite ends of the two galvanized pipe fittings 1 in the inner cavities at both ends of the bent pipe fitting 3; the fastener 4 ensures a firm connection between the galvanized pipe fitting 1 and the bent pipe fitting 3 through components such as a clamp semi-circular ring 10 and a locking bolt 17.

[0036] In this embodiment, the anti-blocking vibration assembly 20 is arranged in the inner cavity included angle of the bent head 6 of the bent pipe fitting 3 and includes an elastic plastic arc-shaped integral cover plate 13 integrally connected to the inner wall of the corner of the bent pipe fitting 3, a receiving cavity 12 formed between the elastic plastic arc-shaped integral cover plate 13 and the inner wall of the bent pipe fitting 3, and a vibration source component arranged in the receiving cavity 12. The vibration source component generates a mechanical force to strike the inner wall of the elastic plastic arc-shaped integral cover plate 13, so that the elastic plastic arc-shaped integral cover plate 13 generates an elastic vibration force, and the cable passing through the bent pipe fitting 3 will not be blocked at the included angle.

[0037] In this embodiment, the vibration source component includes a hand pull rod 5 inserted into the accommodation cavity 12 from the outside of the bent head portion 6 of the bent pipe member 3, an arc-shaped top plate 14 fixed to the free end of the hand pull rod 5 inserted, and a return spring 15 sleeved on the inner end of the hand pull rod 5 located in the accommodation cavity 12. The hand pull rod 5 is part of the anti-blocking vibration assembly 20, and the user can activate the vibration mechanism by pulling it to help prevent blockage in the bent pipe member 3.

[0038] In this embodiment, the return spring 15 is located between the arc-shaped top plate 14 and the inner wall of the accommodation cavity 12, and both ends of the return spring 15 are elastically abutted against the arc-shaped top plate 14 and the inner wall of the accommodation cavity 12 respectively.

[0039] In this embodiment, when the return spring 15 is in its natural state, the curved outer wall of the arc-shaped top plate 14 away from the hand pull rod 5 abuts against the inner wall of the elastic plastic arc-shaped integral cover plate 13. When the hand pull rod 5 is pulled, the arc-shaped top plate 14 compresses the return spring 15, so that energy is stored in the arc-shaped top plate 14 through the return spring 15. The elastic plastic arc-shaped integral cover plate 13 forms part of the anti-blocking vibration assembly 20 and generates elastic vibration force when vibrated, which helps prevent blockage of the cable at the internal angle of the bent pipe member 3. The arc-shaped top plate 14 is connected to the hand pull rod 5, and through the action of the return spring 15, the elastic plastic arc-shaped integral cover plate 13 can be knocked to cause vibration. The return spring 15 provides elastic force for the arc-shaped top plate 14, so that after the hand pull rod 5 is released, the arc-shaped top plate 14 can quickly rebound and impact the elastic vibration portion 16.

[0040] In this embodiment, an elastic vibration portion 16 is provided on the side of the elastic plastic arc-shaped integral cover plate 13 facing the arc-shaped top plate 14. After the arc-shaped top plate 14 stores energy, the hand pull rod 5 is released so that the arc-shaped top plate 14 strikes on the elastic vibration portion 16. The elastic vibration portion 16 and the elastic plastic arc-shaped integral cover plate 13 are of an integral structure and generate vibration after being impacted by the arc-shaped top plate 14, and then the vibration is transmitted to the entire bent pipe member 3.

[0041] In this embodiment, the elastic vibration part 16 is integrally connected to the elastic plastic arc-shaped integral cover plate 13. The materials of the elastic plastic arc-shaped integral cover plate 13 and the elastic vibration part 16 are styrene-butadiene-styrene block copolymer. The styrene-butadiene-styrene block copolymer SBS thermoplastic elastomer has good elasticity and recovery ability, which means that they can deform when subjected to external forces and can quickly return to their original state when the external forces are removed. Such characteristics enable the elastic plastic arc-shaped integral cover plate 13 to generate effective vibrations when struck by the vibration source component and can quickly rebound, thereby continuously applying vibrations to the passing cable. The SBS material has good fatigue resistance and wear resistance, which helps to ensure that the elastic plastic arc-shaped integral cover plate 13 can maintain its structural integrity even under long-term use or repeated vibrations and will not be easily damaged. The SBS material is easy to be processed into complex shapes by injection molding, such as the design of the elastic plastic arc-shaped integral cover plate 13, which can ensure the consistency and accuracy of the product while reducing production costs.

[0042] In this embodiment, annular grooves 7 are provided on the inner walls at both ends of the bent pipe fitting 3. A silicone rubber sealing ring 8 is bonded in each annular groove 7. An anti-slip bump 9 is integrally provided on the inner wall of the silicone rubber sealing ring 8, and the anti-slip bump 9 is in elastic frictional contact with the outer wall of the galvanized pipe fitting 1. The silicone rubber sealing ring 8 is placed in the annular groove 7 to provide a good sealing effect. The anti-slip bump 9 is provided on the silicone rubber sealing ring 8, which increases the friction with the outer wall of the galvanized pipe fitting 1 and helps to improve the sealing performance and stability.

[0043] In this embodiment, each fastener 4 includes two snap rings 10 that are relatively clamped on the outer wall of the circumferential side of the bent pipe fitting 3 and two mounting leg seats 11 that are symmetrically welded to the outer wall of one of the snap rings 10. The mounting leg seats 11 provide additional support points, facilitating the installation and support of the elbow pipe assembly 2. The two ends of the two snap rings 10 are fixedly connected together by locking bolts 17. An installation hole 19 is provided in the lower part of the mounting leg seat 11. The installation hole 19 facilitates the use of screws or other fixing parts to install the elbow pipe assembly 2 to a predetermined position.

[0044] In this embodiment, rubber protective washers 18 are provided on the inner walls of the two snap rings 10, and the rubber protective washers 18 are sleeved on the outer wall of the circumferential side of the bent pipe fitting 3. The rubber protective washers 18 are placed on the inner walls of the snap rings 10 to protect the bent pipe fitting 3 from direct extrusion damage and increase the friction of the contact surface.

[0045] Working principle:

[0046] This high-strength elbow for splicing galvanized pipes fixes two galvanized pipe fittings 1 to both ends of the elbow pipe fitting 3 through fasteners 4. The fasteners 4 include a clamp semi-circular ring 10 and a locking bolt 17, which closely surround the outer wall of the elbow pipe fitting 3 and provide an additional sealing effect through a rubber protective washer 18. At the same time, annular grooves 7 are provided on the inner walls at both ends of the elbow pipe fitting 3, and silica gel sealing rings 8 are embedded therein. The anti-slip bumps 9 on the silica gel sealing rings 8 contact the outer wall of the galvanized pipe fitting 1, increasing the friction force and ensuring good sealing performance and connection stability. An anti-blocking vibration assembly 20 is arranged inside the bend part 6 of the elbow pipe fitting 3. The core of this assembly is an elastic plastic arc-shaped integral cover plate 13, which forms a receiving cavity 12 with the inner wall of the elbow pipe fitting 3. The vibration source component is arranged in the receiving cavity 12 and consists of a hand pull rod 5, an arc-shaped top plate 14, and a return spring 15. When the anti-blocking function needs to be activated, the user can manually pull the hand pull rod 5 located outside.

[0047] Pulling the hand pull rod 5 causes the arc-shaped top plate 14 to compress the return spring 15, storing energy in the spring. When the hand pull rod 5 is released, the return spring 15 releases the stored energy, pushing the arc-shaped top plate 14 to move quickly and strike the elastic vibration part 16 of the elastic plastic arc-shaped integral cover plate 13. The elastic plastic arc-shaped integral cover plate 13 vibrates due to the impact, and this vibration is transmitted to the entire interior of the elbow pipe fitting 3, especially the area where the cable passes through. In this way, any accumulation or entanglement of the cable inside the elbow pipe fitting 3 will be scattered by the vibration, thus avoiding potential blockage problems.
