Description

Technical Field

[0001] The present invention relates to the technical field of long cylindrical structures, in particular to a detachable long cylindrical installation and positioning structure. Background Art

[0002] A cylinder refers to a plane with a fixed straight line and a moving line. When the plane rotates around the fixed straight line, the surface formed by the moving line is called the rotation surface, the fixed straight line is called the axis of the rotation surface, and the moving line is called the generatrix of the rotation surface. If the generatrix is a straight line parallel to the axis, then the generated rotation surface is called a cylindrical surface. Existing long cylindrical shapes are commonly seen in water pipes, cables, and natural gas pipelines, most of which are cylindrical in shape.

[0003] The existing mounting brackets are somewhat inconvenient to splice in order to adapt to different lengths of the long cylinders, and the existing positioning structure is not convenient for adjusting the verticality and elevation thereof. Summary of the Invention

[0004] Based on this, the purpose of the present invention is to provide a detachable long cylindrical installation and positioning structure to solve the technical problems of being inconvenient to splice the long cylindrical fixing seat and being inconvenient to adjust the verticality and elevation of the long cylinder.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0011] Two trapezoidal slides are distributed in an inverted eight-shaped top surface. The two trapezoidal slides are threadedly connected to the two sections of the threaded bidirectional threaded rod and slide along the rear end of the fixed seat within the range of the cylindrical recess under the rotation of the threaded connecting rod. The rear end of the fixed seat is fixed with a fixed threaded seat for rotatably mounting the two ends of the bidirectional threaded rod.

[0012] As a further solution of the present invention, a welding groove is provided below the slide groove.

[0013] As a further solution of the present invention, an arc-shaped sliding groove matching the arc-shaped limiting rack is opened on the inner wall of the fixing seat.

DETAILED DESCRIPTION

[0025] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be understood as limiting the present invention.

[0026] The following describes an embodiment of the present invention based on its overall structure.

[0027] A detachable long cylindrical mounting and positioning structure, such as Figures 1 to 3 As shown, it mainly includes a fixed seat 2, a rack rod 21, an arc-shaped limiting rack 24, a gear transmission mechanism and a trapezoidal slide 4.

[0028] The bottom end of the long cylinder 1 is slidably installed on the top surface of the fixed seat 2. A cylindrical recess 28 is formed downward in the middle of the top surface of the fixed seat 2, on which the long cylinder 1 can be placed flat. An installation space is set inside the fixed seat 2. Strip openings 27 are opened on both sides of the top surface of the fixed seat 2 along the axial direction of the cylindrical recess 28. The strip openings 27 and the installation space inside the fixed seat 2 are interconnected, that is, the installation space can be connected to the outside through the strip openings 27.

[0029] Two rack rods 21 are symmetrically fixed on both sides of the front end of the fixed base 2. The two rack rods 21 are parallel to each other and perpendicular to the front end face of the fixed base 2. The front end face of the fixed base 2 is perpendicular to the axis of the cylindrical recess 28 on it. Slide grooves 25 matching the rack rods 21 are opened on both sides of the rear end of the fixed base 2, and one side of the slide groove 25 is connected to the installation space.

[0030] The two arc-shaped limiting racks 24 are slidably installed in the installation space corresponding to the positions of the cylindrical recesses 28 and can slide out to the outside of the fixing seat 2 through the strip-shaped opening 27 to fix the long cylinder 1 on the cylindrical recess 28. Preferably, the inner wall of the fixing seat 2 is provided with an arc-shaped sliding groove that matches the arc-shaped limiting racks 24, and the curvature of the arc-shaped sliding groove is consistent with the curvature of the cylindrical recess 28. Figure 3 As described above, in the initial state of sliding out of the fixing seat 2 , the sum of the arc lengths of the two arc-shaped limiting racks 24 is greater than the diameter of the cylindrical recess 28 . After sliding out of the fixing seat 2 , the top ends are tightly against the outer wall of the long cylinder 1 to fix the long cylinder 1 .

[0031] Two gear transmission mechanisms are installed in the installation space. Each gear transmission mechanism is connected between a rack rod 21 and an arc-shaped limit rack 24. The gear transmission mechanism converts the linear displacement of the rack rod 21 along the slide 25 into the rotational movement of the arc-shaped limit rack 24 around the cylindrical recess 28. One side of the slide 25 is connected to the installation space inside the fixed base 2 by a gear groove. Each gear transmission mechanism includes a first gear 22, a first bevel gear 22, a second gear 231, and a second bevel gear 23. The first gear 22 is rotatably mounted within the mounting space and meshes with the rack rod 21 via a gear groove. The second gear 231 is rotatably mounted within the mounting space and meshes with the arcuate limit rack 24. One end of the first gear 22 is coaxially fixed to the first bevel gear 22, while one end of the second gear 231 is coaxially fixed to the second bevel gear 221. The first bevel gear 22 and the second bevel gear 221 mesh with each other, so that the rotation of the first gear 22 drives the second gear 231. The rotation of the second gear 231 drives the arcuate limit rack 24 to rotate about the cylindrical recess 28 and slide within the arcuate slot 25 defined in the inner wall of the fixed base 2. The rotation of the first gear 22 is driven by the rack rod 21 at the front end of the other fixed base sliding in the slot 25, contacting and meshing with the first gear 22, thereby driving the rotation of the first gear 22.

[0032] Furthermore, a block groove 211 is provided at the upper end of the rack rod 21, and the top ends of the slide grooves 25 on both sides of the fixed seat 2 correspond to the positions of the block grooves 211 and are elastically connected to the limiting block 26 through a limiting spring, and the rack rod 21 and the slide groove 25 are limited and fixed by the limiting block 26 and the block groove 22.

[0033] Furthermore, welding grooves 251 are provided below the slide grooves on both sides of the fixing seat 2, and their function is to allow the rack rod at the front end of the rear fixing seat to slide into the slide groove at the rear end of the front fixing seat and slide into place. After the limit block and the block groove are engaged, the front and rear fixing seats are firmly welded through the welding grooves 251, thereby strengthening the connection between the front and rear fixing seats.

[0034] The top surfaces of the two trapezoidal slides 1 are distributed in an inverted eight-shaped shape in order to facilitate the placement of the long cylinder 1. Figure 1 As shown, the two trapezoidal slides 1 are threadedly connected to the two sections of the threaded bidirectional threaded rod 3 and slide along the rear end surface of the fixed seat 2 within the range of the cylindrical recess 28 under the rotation of the threaded connecting rod 3. The rear end surface of the fixed seat 2 is fixed with a fixed threaded seat for rotating installation of the two ends of the bidirectional threaded rod 3.

[0035] The working principle of the present invention is as follows: the elongated cylinder 1 is placed in the arc-shaped recess 28 at the top of the fixed seat 2, and the rack rod 21 fixed at the front end of the other group of fixed seat 2 slides into the slide groove 25 at the rear end of the previous group of fixed seat 2, driving the first gear 22 of the previous group of fixed seat 2 to rotate, so that the first bevel gear 221 rotates, and then drives the second bevel gear 23 meshing with the first bevel gear 221 to rotate, so that the transmission gear 231 rotates, driving the arc-shaped limiting rack 24 to slide in the arc-shaped slide groove opened on the inner wall of the fixed seat 2, and then makes the top end of the arc-shaped limiting rack 24 extend out of the fixed seat and close to the outer wall of the elongated cylinder 1. At this time, the limiting block is reset and engaged with the block groove under the action of the limiting spring, thereby achieving the effect of fixing the elongated cylinder 1, and rotating the two-way threaded rod 3 can make the two groups of trapezoidal slides 4 slide on the rear end face of the fixed seat 2, thereby achieving the effect of facilitating the adjustment of the verticality and elevation of the elongated cylinder 1.

[0036] When the long cylinder needs to be disassembled, it is only necessary to slide the rack rod 21 at the front end of the rear set of fixing seats out of the sliding groove of the front set of fixing seats. The operation is simple, time-saving and labor-saving.

[0037] Although an embodiment of the present invention has been shown and described, this specific embodiment is merely an explanation of the present invention and is not a limitation of the invention. The specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiment without creative contribution as needed without departing from the principles and purpose of the present invention. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
