DETAILED DESCRIPTION

[0027] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0028] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0029] Example

[0030] The following is further described in conjunction with specific embodiments. Figure 1-Figure 3As shown, the utility model is a pipe connection clamp for building construction, including a base 1, a handle 12 is fixedly welded on the base 1, a pair of clamps 2 are provided and are arranged in an arc shape, and one side of the arc-shaped recess 21 of the clamp 2 is arranged toward the pipe and is used to abut against the side wall of the pipe, a pair of clamps 2 are arranged opposite to each other and are slidably arranged on the base 1, and a retaining edge 22 is fixedly welded integrally on the side walls of the clamps 2 that are close to each other, and is used to be received on the outer peripheral wall of the flange of the pipe.

[0031] The main plug rod 23 is fixedly welded on the side walls of the splint 2 that are close to each other, and is located in the middle of the splint 2 and is used to be inserted into the bolt hole of the flange. The main plug rod 23 is cylindrical and has a guiding bevel at the end. Its diameter is slightly smaller than the diameter of the bolt hole of the flange.

[0032] Reference Figure 1 and Figure 2 As shown, in order to further limit the position of the flange, a pair of clamps 2 are provided with multiple plug holes 24 on the side walls close to each other, and at least one auxiliary plug rod 4 is provided. The auxiliary plug rod 4 is cylindrical, and one end of the auxiliary plug rod 4 is inserted into the plug hole 24, and the other end extends out of the plug hole 24. Therefore, the number and position of the auxiliary plug rods 4 can be adaptively adjusted according to the number and position of the bolt holes of the flange. The end of the auxiliary plug rod 4 extending out of the plug hole 24 is spherical, and the length of the auxiliary plug rod 4 extending out of the plug hole 24 is less than the length of the main plug rod 23. In this way, the main plug rod 23 can be used for alignment and limiting first, and then the auxiliary plug rod 4 can be inserted into the bolt hole of the flange for insertion and positioning, which is convenient for the operator to operate.

[0033] Reference Figure 2 and Figure 3 As shown, in order to facilitate the fixation of the auxiliary rod 4, an annular groove 41 is provided along the circumferential direction at one end of the auxiliary rod 4 inserted into the plug-in hole 24, and a rubber ring 42 is embedded in the annular groove 41. The outer peripheral wall of the rubber ring 42 protrudes from the outer peripheral wall of the auxiliary rod 4. After the auxiliary rod 4 is inserted into the plug-in hole 24, the rubber ring 42 can be squeezed and deformed and abut against the inner wall of the plug-in hole 24, thereby fixing the auxiliary rod 4.

[0034] Reference Figure 1 and Figure 2As shown, a pair of splints 2 are each installed with a support assembly 5 on one side facing away from each other, and the support assembly 5 is used to support the outer wall of the pipe. Specifically, the support assembly 5 includes an extension rod 51, a hinge rod 52 and a support plate 53. The extension rod 51 is fixedly welded to the outer side walls of a pair of splints 2 facing away from each other. A hinge groove 511 is provided at the end of the extension rod 51. One end of the hinge rod 52 is hinged to the hinge groove 511 position of the extension rod 51. The hinge groove 511 is closed on the side close to the base 1 to limit the hinge rod 52 from rotating to the same line as the extension rod 51. The support plate 53 is fixedly connected to the other end of the hinge rod 52 and is used to support the outer wall of the pipe. In this embodiment, the support plate 53 has the same shape as the splint 2.

[0035] Reference Figure 3 As shown, a spring clip 54 is provided at the hinge axis position of the hinge rod 52 and the extension rod 51. One end of the spring clip 54 is fixedly connected to the hinge rod 52, and the other end is fixedly connected to the extension rod 51. The spring clip 54 can play a resetting role, so that the extension rod 51 and the hinge rod 52 maintain an obtuse angle state, which is convenient for the support plate 53 to be received on the outer wall of the pipe in advance, and gradually rotated until the extension rod 51 and the hinge rod 52 are at a 180-degree state to support the two pipes to be connected. In other implementations, the spring clip 54 can be replaced with a torsion spring.

[0036] Reference Figure 1 and Figure 2 As shown, in order to facilitate driving a pair of splints 2 to move closer to or away from each other and fix them to the moved position, the driving member 3 includes a bidirectional screw 31 and a motor 32. Two sliding grooves 11 are provided on both sides of the side wall of the base 1 away from the handle 12 along the length direction. A slider 25 is fixedly provided on the splint 2. The slider 25 is slidably connected in the sliding groove 11. The slider 25 is threadedly sleeved on the bidirectional screw 31. The motor 32 is fixedly mounted on the base 1. The rotating shaft of the motor 32 is coaxially fixedly connected to the bidirectional screw 31. In other implementations, the motor 32 can be replaced by a rotating handle.

[0037] Reference Figure 2 As shown, the threads on both sides of the bidirectional screw 31 transition from sparse at the far end to densely arranged in the middle, and the bidirectional screw 31 passes through the through hole 521 of the slider 25 and is fixedly welded with a limit block 252. The limit block 252 and the thread groove of the bidirectional screw 31 are arranged to slide relative to each other. When the motor 32 drives the bidirectional screw 31 to rotate, a pair of splints 2 can move quickly under the action of the sparse threads. When they are to be clamped to the side wall of the flange, the moving speed of the pair of splints 2 will slow down and gradually clamp to the side wall of the flange, thereby improving the clamping efficiency and preventing the splint 2 from damaging the flange during rapid movement.

[0038] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
