[0029] In addition, it should be understood that, for the convenience of description, the sizes of the various components shown in the drawings are not drawn in accordance with the actual proportional relationship, for example: the thickness or width of certain layers can be exaggerated relative to other layers.

[0030] It should be noted that similar reference numbers and letters represent similar items in the following drawings, and therefore, once an item is defined or described in one drawing, it will not need to be further specifically discussed and described in the description of subsequent drawings.

[0031] To solve the technical problems in the background art, as shown in Figures 1-5 The present application provides a technical solution: a metal pipe drilling support, comprising:

[0032] The fixed seat 1 is made of a solid metal material, and has good stability and durability. The fixed seat 1 has a spherical groove 2 located at the upper part of the fixed seat 1, which is semispherical in shape to accommodate the rotation of the spherical swivel head 4. The size of the spherical groove 2 is matched with the spherical swivel head 4, which is fixedly connected to the first hoop body 6 and can rotate in the spherical groove 2. The rotation of the spherical swivel head 4 helps to adjust the position of the metal pipe to meet different drilling needs. The top of the spherical groove 2 is provided with a through hole 3 for installing a semispherical protrusion 5. The semispherical protrusion 5 is threadedly connected with the spherical swivel head 4. The plane of the semispherical protrusion 5 abuts against the bottom surface of the fixed seat 1. The semispherical protrusion 5 can increase the contact area between the spherical swivel head 4 and the fixed seat 1, and improve the stability. Under the limitation of the semispherical protrusion 5, the spherical swivel head 4 can only rotate around the axis of the semispherical protrusion 5 in the spherical groove 2. The first hoop body 6 is made of a metal material, and has an arc-shaped inner surface in contact with the metal pipe, which can tightly fit the metal pipe to ensure the stability of the metal pipe during the drilling process. The second hoop body 7 is arc-shaped, and two second hoop bodies 7 are symmetrically arranged. One end of the second hoop body 7 is hingedly connected to the first hoop body 6, and the other end is provided with a fastening plate 8. The fastening plate 8 is made of the same material as the second hoop body 7, and is provided with a threaded hole 9 on the top. Two fastening plates 8 are tightly connected by a screw rod 10 to enclose the first hoop body 6 and the two second hoop bodies 7.

[0033] Further, the limiting ring 11 is a U-shaped ring structure having two symmetric arm portions and a bottom portion connecting the two arm portions. The material of the limiting ring 11 is high-strength stainless steel to ensure its stability and durability during use. The two ends of the limiting ring 11 are respectively hingedly connected to the two sides of the second hoop body 7. Specifically, the two arm ends of the limiting ring 11 are provided with hinge holes, and the two sides of the second hoop body 7 are provided with hinge shafts at the corresponding positions, and the hinge shafts pass through the hinge holes, so that the limiting ring 11 can rotate around the hinge shafts. When the limiting ring 11 rotates around the hinge shafts, its U-shaped structure can be sleeved on the other second hoop body 7. In this way, the two second hoop bodies 7 are connected by the limiting ring 11 to form a stable support structure.

[0034] It should be noted that the limiting ring 11 is provided with a through hole 12, which is arranged at the middle position of the limiting ring 11, that is, the bottom portion. The through hole 12 is used to accommodate the screw rod 10 to pass through. In this way, the limiting ring 11 not only plays a sleeving and fastening role, but also facilitates the positioning of the screw rod 10 in the unfastened state, and the screw rod 10 is not easy to come off. In addition, when the limiting ring 11 is sleeved on the other second hoop body 7, the screw rod 10 passes through the through hole 12 and the fastening plates 8 of the two second hoop bodies 7 in sequence, forming a further strengthening effect.

[0035] Further, the cross sections of the first hoop body 6 and the second hoop body 7 are both I-shaped. The I-shaped cross section can improve the rigidity and strength of the first hoop body 6 and the second hoop body 7, making them more stable when bearing pressure. Compared with square, circular and other cross sections, the I-shaped cross section has higher strength under the same material.

[0036] It should be noted that the anti-skid layer 13 is arranged on the arc-shaped inner surface of the first hoop body 6 and the second hoop body 7. The anti-skid layer 13 can be rubber, plastic, silicone or other materials with high friction coefficient to increase the friction of the contact surface and prevent sliding. Due to the presence of the anti-skid layer 13, the structure is not easy to slide and shift when subjected to external force, thereby ensuring its stability and safety. The flexible anti-skid layer 13 not only has the effect of preventing sliding, but also enhances the adaptability of the first hoop body 6 and the second hoop body 7 to different pipe diameters. It also has a protective effect on the metal pipe.

[0037] Further, in order to further improve the adaptability to metal pipes of different sizes, fastening holes 14 are additionally provided. The fastening holes 14 are arranged on the second hoop body 7 and have an internal thread structure for threaded connection with the fastening bolts 15. The fastening bolts 15 are used to fix and fasten the assembly. The diameter and length of the fastening holes 14 are designed according to actual needs to ensure that the fastening bolts 15 can be smoothly inserted and achieve fastening of the metal pipe of the inserted support. The two fastening bolts 15 arranged on the second hoop body 7 jointly abut the metal pipe, plus the lifting of the first hoop body 6, jointly forming a limit to the metal pipe.

[0038] It should be noted that the boss 17 is arranged on the two side surfaces of the first hoop body 6, which has the same shape as the first hoop body 6 and has an arc-shaped inner surface. The size of the boss 17 matches the first hoop body 6 to ensure the stability and sealing of the overall structure. Specifically, the boss 17 is arranged as follows: the boss 17 is tightly attached to the two side surfaces of the first hoop body 6 to form a whole hoop body structure, which is generally welded or integrally formed by casting with the first hoop body 6. The arc-shaped inner surface of the boss 17 cooperates with the arc-shaped inner surface of the first hoop body 6 to ensure that the metal pipe can be prevented from being lifted by the boss 17 and the first hoop body 6, which jointly form a lift for the metal pipe.

[0039] Further, the anti-skid protrusions 18 are arranged on the surface of the anti-skid sheet 16. The anti-skid protrusions 18 are made of the same material as the anti-skid sheet 16 to ensure consistency of overall performance. The anti-skid protrusions 18 are in the shape of a cylinder.

[0040] It should be noted that the support leg (19) is arranged on the fixing seat (1) for supporting the fixing seat (1). At the same time, in order to improve the bottom surface of the fixing seat 1, a space is left to accommodate the hemispherical protrusion 5.

[0041] While embodiments of the application have been shown and described, it is to be understood that the embodiments described are merely exemplary and that changes can be made in detail without departing from the principles and spirit of the application. The scope of the application is therefore defined by the appended claims and their equivalents.
