[0026] See also Figure 1 and Figure 2 The utility model provides a technical solution: a U-shaped pipe clamp capable of adjusting tightness, comprising

[0027] A clamping member 110, the clamping member 110 includes an extrusion block 111;

[0028] The bottom transmission member 120 includes a mounting plate 121 and a first screw rod 122. The first screw rod 122 is mounted on both ends of the mounting plate 121 for limited rotation. Extrusion blocks 111 are mounted on the first screw rods 122 at both ends of the mounting plate 121 for limited transmission.

The transmission members 130 on both sides and the bottom transmission member 120 cooperate with each other to adjust the clamping member 110, so that the clamping member 110 can clamp the pipeline in multiple directions.

[0030] See also Figure 2 and Figure 3 There are two groups of clamping members 110, each group is provided with two. The two groups of extrusion blocks 111 surround a rectangle, and the middle part of the two groups of clamping members 110 surrounds an elliptical through hole. The curvature inside the two groups of extrusion blocks 111 is set according to needs, which is convenient for clamping pipes of different sizes. A plurality of limit rails 114 are evenly spaced inside each extrusion block 111, and a matching extrusion strip 112 is provided inside the limit rail 114 for limiting. Limited card slots 113 are provided on both sides of the matching extrusion strip 112, and the inside of the limit rail 114 is provided with a limiting protrusion corresponding to the limited card slot 113. The matching extrusion strip 112 is used for the extrusion block 111 to relieve the damage of the pipe caused by the extrusion when the extrusion block 111 is extruding the outer wall of the pipe, and at the same time increase the stability of the connection with the pipe, and prevent the pipe from rotating inside the extrusion block 111.

[0031] The bottom transmission member 120 further includes a bearing seat 124, which is fixedly mounted in the middle of the mounting plate 121. Both sides of the bearing seat 124 are limitedly rotatably connected to the first screw rod 122, and the other ends of the first screw rod 122 are respectively limitedly rotatably connected to the two ends of the mounting plate 121. A group of extrusion blocks 111 are respectively transmission-connected to the two first screw rods 122, and the bottom of the extrusion block 111 is limitedly slidably mounted on the mounting plate 121. One end of the first screw rod 122 close to the end of the mounting plate 121 is fixedly sleeved with a ring handle 123. The first limiting slide bar 125 is fixedly connected to both sides of the bottom of the extrusion block 111, and grooves matching the first limiting slide bar 125 are provided on both sides of the mounting plate 121. By rotating the ring handle 123, the ring handle 123 transmits the first screw rod 122. At this time, the first screw rod 122 will be threaded with the extrusion block 111, so that the extrusion block 111 is displaced through the cooperation of the first limiting slide bar 125, so as to facilitate the adjustment of the distance between the two extrusion blocks 111.

[0032] See also Figures 2 to 4 The transmission parts 130 on both sides also include a second limiting slide bar 135, which is fixedly installed on both sides of the top of the extrusion block 111 above the two first screw rods 122. The back of another group of extrusion blocks 111 is limited and slidably connected to the second limiting slide bar 135, and is also transmission-connected to the second screw rod 131. The bottom of the second screw rod 131 is limited and rotationally connected to the top of the bottom group of extrusion blocks 111. The top of the second screw rod 131 is fixedly connected to the limit block 132, and the top limit sleeve of the limit block 132 is connected with a handle 136. The bottom of the second screw rod 131 is fixedly connected to the limit ring 133, and the outer limit of the limit ring 133 is rotatably connected to the limit seat 134. The bottom of the limit seat 134 is fixedly installed above the extrusion block 111 of the bottom group. The handle 136 is detachably installed above the limit block 132. By rotating the handle 136, the handle 136 drives the second screw rod 131 to transmit the extrusion block 111, and the extrusion block 111 moves up and down under the restriction of the second limit slide 135. The first limit slide 125 and the second limit slide 135 are both isosceles trapezoidal settings, which are convenient for limiting and preventing derailment during sliding.

[0033] Working principle: observe the approximate size of the pipeline, adjust the ring handle 123 and the handle 136, the ring handle 123 drives the first screw rod 122 to drive the extrusion block 111 to move outward (inward) to increase (reduce) the spacing, which is convenient for positioning pipelines of different sizes. At the same time, adjust the handle 136 to drive the second screw rod 131, and the second screw rod 131 drives the extrusion block 111, so that the extrusion block 111 cooperates with the second limit slide bar 135 to move upward (downward) to increase (reduce) the spacing, which is convenient for wrapping and locking pipelines of different sizes. The pipeline is in multiple extrusion blocks 111, and the extrusion bar 112 will squeeze the outer wall of the pipeline to increase the locking effect. If you need to increase (reduce) the spacing, just adjust the ring handle 123 and the handle 136. There is no need to disassemble the pipeline when installing it.
