[0031] 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 considered to belong to the present utility model.
[0032] The scope of protection of utility models.
[0033] Referring to Figures 1-3, one embodiment of this utility model provides: a wear-resistant, adjustable-angle elbow, including a connecting pipe 1, which is part of the elbow and hinged to a connecting pipe 2, together forming an elbow structure that can change the pipe angle. The connecting pipe 2 is hinged to the left side of the connecting pipe 1, and the connecting pipe 1...
[0034] 1. Hinged joint, allowing rotation relative to connecting pipe 1 to adjust the angle, while connecting pipe 1 and connecting pipe 2...
[0035] 2. Made of wear-resistant material, the inner left wall of connecting pipe 1 and the inner right wall of connecting pipe 2 are connected by a corrugated pipe.
[0036] 5. Fixed connection: Connecting pipe 1 and connecting pipe 2 are connected by corrugated pipe 5 to form a closed elbow structure. The front right side of connecting pipe 2 has a scale, and the right side of connecting pipe 1 near the scale has a pointer. The pointer and the scale work together to visually display the rotation angle of the elbow so that the user can accurately adjust it to the required angle. The inner right side of connecting pipe 2 has an adjustment component, which includes a limiting post 31. Through cooperation with the limiting groove 33, the relative angle between connecting pipe 1 and connecting pipe 2 is limited at different positions to ensure the stability of the elbow angle during use.
[0037] Furthermore, the outer side of the limiting post 31 is slidably connected to the inner wall of the connecting pipe 2. The front side of the limiting post 31 is elastically connected to the connecting pipe 2 via a compression spring 32. When adjusting the angle, the limiting post 31 moves against the elastic force of the compression spring 32. After adjustment, the compression spring 32 causes the limiting post 31 to remain in a specific position, enhancing the stability after angle adjustment. The front side of the connecting pipe 1 has a limiting groove 33, which is provided in multiple sets to provide a sliding track and limiting position for the limiting post 31. Different positions of the limiting groove 33 correspond to different bend angles, realizing precise adjustment and fixation of the angle. The limiting post 31 slides on the inner wall of the limiting groove 33. The inner wall of the connecting pipe 2 is slidably connected to a limiting rod 34, which cooperates with the limiting post 31 to limit and fix the limiting post 31, further enhancing the stability and reliability of angle adjustment. The outer side of the limiting rod 34 slides on the front side of the limiting post 31.
[0038] Reference Figure 2 - Figure 4 The limiting rods 34 are provided in multiple sets, and the multiple sets of limiting rods 34 are arranged in a circular array with the hinge point of connecting pipe 1 and connecting pipe 2 as the center, which can simultaneously limit multiple sets of limiting posts 31.
[0039] The positioning mechanism improves the stability of connecting pipe 1 and connecting pipe 2. A pressing block 35 is fixedly connected to the front side of the limiting rod 34 near the hinge point of connecting pipe 1 and connecting pipe 2. The front side of the pressing block 35 is set as an inclined surface, which cooperates with the inclined surface of the inner wall of the push block 36. When the push block 36 moves, the pressing block 35 is pushed towards the center by the action of the inclined surface, so that the limiting rod 34 slides out from the front side of the limiting post 31, releasing the limitation on the limiting post 31. The push block 36 is slidably connected to the inner wall of connecting pipe 2.
[0040] Furthermore, the inner rear wall of the push block 36 is set as an inclined surface. The guide groove 38 on the inner wall of the push block 36 is slidably connected to the outer side of the extrusion block 35. When subjected to external force, the push block 36 moves and pushes the extrusion block 35 through the inclined surface to control the limit rod 34. The rear side of the push block 36 is elastically connected to the connecting pipe 2 through the return spring 37. The elastic force of the return spring 37 causes the push block 36 to return to the initial position. The inner wall of the push block 36 is provided with a guide groove 38 to guide the movement of the extrusion block 35 and ensure that the extrusion block 35 can move accurately towards the center when the push block 36 moves, thereby controlling the position of the limit rod 34 and realizing the locking and unlocking of the limit post 31. The outer side of the extrusion block 35 is slidably connected to the inner wall of the guide groove 38. Multiple sets of limit posts 31 and compression springs 32 are provided to improve the stability after adjustment.
[0041] Referring to Figures 1 and 5, a clamping assembly is provided on the inner wall of the connecting pipe 1. The clamping assembly includes a stabilizing column 41, which provides a support structure for the installation and sliding of the roller 42. The outer side of the stabilizing column 41 is fixedly connected to the inner wall of the rear side of the connecting pipe 1, and the roller 42 is slidably connected to the outer side of the stabilizing column 41. By sliding on the stabilizing column 41, the corrugated pipe 5 passing through the bend can be clamped. The outer side of the roller 42 is made of rubber, which can increase the friction with the clamped object, prevent the object from sliding in the bend, and avoid damage to the surface of the corrugated pipe 5. The diameters at both ends of the roller 42 are larger than the diameter at the middle, which better clamps the corrugated pipe 5 and improves the clamping effect. Multiple sets of rollers 42 are provided. The outer side of the roller 42 slides on the inner wall of the connecting pipe 1, and the outer side of the roller 42 slides on the outer side of the corrugated pipe 5.
[0042] Furthermore, a bidirectional threaded rod 43 is rotatably connected to the inner wall of the front side of the connecting pipe 1. By rotating the bidirectional threaded rod 43, the position of the roller 42 on the stabilizing column 41 can be adjusted, thereby achieving the adjustment of different sizes.
[0043] The bellows 5 clamps the elbow, improving its versatility. The double-threaded rod 43 is threaded to the inner wall of the front part of the roller 42. The top of the double-threaded rod 43 is fixedly connected to the torsion cap 44, and the outer side is provided with an anti-slip groove, which makes it convenient for the operator to rotate the double-threaded rod 43 to adjust the clamping components, thus improving the ease of use.
[0044] Working principle: When it is necessary to adjust the angle of the elbow, an external force is applied to the push block 36, causing the push block 36 to slide on the inner wall of the connecting pipe 2. When the push block 36 moves, it pushes the extrusion block 35 towards the center through the action of the inclined surface, which drives the limit rod 34 to slide out from the front side of the limit post 31, releasing the limit on the limit post 31.
[0045] At this time, an external force is applied to the second connecting pipe 2 to make it rotate relative to the first connecting pipe 1. During the rotation, the limiting post 31 is squeezed by the first connecting pipe 1, overcomes the elastic force of the compression spring 32, slides on the inner wall of the second connecting pipe 2, and slides out from the current limiting groove 33. As the second connecting pipe 2 rotates, the pointer on the right side of the first connecting pipe 1 moves on the scale on the right front side of the second connecting pipe 2. The user can intuitively judge the rotation angle of the elbow according to the scale indicated by the pointer so as to adjust it to the required angle.
[0046] To prevent the bellows 5 from sliding inside the bend and to avoid damage to the surface of the object, the torsion cap 44 at the top of the bidirectional threaded rod 43 is rotated, causing the bidirectional threaded rod 43 to rotate. This causes the two sets of rollers 42 to slide on the stabilizing column 41 and move the rollers 42 towards the center, clamping the bellows 5. This avoids unnecessary friction and wear on the bellows 5, effectively extends the service life of the bellows 5, and ensures the reliability of the device operation.
[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
