[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.
[0023] Example
[0024] Figure 1 - Figure 4 What is shown is a schematic diagram of the overall structure of a specific embodiment of the utility model. Figure 1 - Figure 4 In the figure, the buried municipal pipeline includes a support pipe 1 and a support rod 2 installed on the outside of the support pipe 1. The upper half of the support rod 2 is installed with a self-adjusting support mechanism, and the lower half of the support rod 2 is installed with a buffer support mechanism.
[0025] The self-adjusting support mechanism includes a limit support plate 3, a limit block 301, a guide groove 302, a connecting rod 303, a guide plate 304, a rotating support block 305, and a positioning block 306. The limit block 301 is installed on the opposite sides of the upper end of the limit support plate 3. The guide groove 302 runs through the limit support plate 3 and the upper and lower ends of the limit block 301. The connecting rod 303 is plugged into the guide groove 302. The connecting rod 303 is rotatably connected to the guide plate 304. The positioning block 306 is installed at the lower end of the guide plate 304. The upper half of the guide plate 304 is rotatably installed between the two rotating support blocks 305.
[0026] The buffer support mechanism includes a support tube 4, a limit plate 401, a spring 402, and a limit ring 403. The limit ring 403 is installed on the inner wall of the support tube 4, and several limit rings 403 are distributed vertically. The spring 402 is installed on the lower half of the inner wall of the support tube 4, and the limit plate 401 is located between the two limit rings 403.
[0027] Among them, the end of the connecting rod 303 away from the guide plate 304 is rotatably connected to the support rod 2, the rotating support block 305 is installed on the outside of the support tube 1, the support rod 2 is plugged into the limiting support plate 3, the support rod 2 is plugged into the support tube 4, and the limiting disk 401 is installed on the outside of the support rod 2, and the limiting disk 401 is located inside the support tube 4, and the upper end of the spring 402 is installed on the lower end surface of the support rod 2.
[0028] First, based on the simultaneous support of the support tube 1 by the support rod 2 and the guide plates 304 on both sides, it can be used in combination with the soil, focusing on strengthening the support of the lower half of the support tube 1. At the same time, under the connection of the support rod 2 and the guide plates 304 at both ends of the connecting rod 303, when the support rod 2 is pressed and moved downward, it can drive the connecting rods 303 on both sides and the guide plates 304 to shrink toward the middle, so that the guide plate 304 rotates at one end of the support block 305 under the rotation limit, and adjusts the position of the guide plate 304 and the positioning block 306, so that the positioning block 306 moves to between the next set of limit blocks 301, and the limit plate 401 moves to between the next set of limit rings 403, thereby Under the conductive support of the support rod 2, the force of the support tube 1 being pressed downward is converted into the force of the angle change of the guide plates 304 on both sides, so that the support tube 1 has the effect of automatically adjusting the support when under pressure, and under the elastic support of the spring 402 and the limiting connection with the limiting ring 403, it provides limitation and support for the support rod 2. Under the clamping limit of the limiting block 301, the positioning block 306 is prevented from retreating and resetting, ensuring the stability and accuracy of the automatic adjustment of the limit when the device is used, thereby combining the self-adjusting support mechanism with the buffering support mechanism to improve the effect of the device's automatic adjustment of the distance when the pressure increases, and ensuring the stability of the support tube 1 during long-term use.
[0029] Figure 2 In the embodiment, the self-adjusting support mechanism further includes a positioning groove 307 , which is located between the adjacent limiting blocks 301 on both sides, and the positioning block 306 is connected to the positioning groove 307 by a clamping arrangement.
[0030] The inner side of the limit block 301 is an inclined structure, the lower half of the outer surface of the limit block 301 is an inclined structure, and the upper half of the outer surface of the limit block 301 is an arc structure.
[0031] With the combined use of the adjacent limit blocks 301, both sides of the positioning groove 307 have limit specifications that are compatible with the positioning block 306, thereby ensuring the accurate limiting of the positioning block 306 while improving the stability of the limited state of the positioning block 306, and the two sides of each limit block 301 are respectively set to an arc shape and a straight line shape, so that it can provide support for the movement of the positioning block 306 and effectively prevent it from sliding in the opposite direction when supporting.
[0032] Figure 2 In the embodiment, two rotating support blocks 305 operate as a group, and the two groups of rotating support blocks 305 at the same horizontal position are symmetrically distributed.
[0033] The two rotating support blocks 305 provide rotating support for the guide plate 304 on one side at the same time. Under the premise that the rotating support blocks 305 on both sides provide rotating support for the guide plates 304 on both sides at the same time, the connection angle and support point of the guide plate 304 are guaranteed to be stable and accurate when the guide plate 304 is rotated and adjusted.
[0034] Figure 4 In the embodiment, there are a plurality of limiting rings 403 , and the distance between every two limiting rings 403 is the same, and the distance between two adjacent limiting rings 403 is slightly greater than the height of the limiting plate 401 .
[0035] The spring 402 is located in the middle of the limiting ring 403 , and the specification of the limiting disk 401 is larger than the specification of the joint between the support rod 2 and the support tube 4 .
[0036] First, the limiting plate 401 is located between two adjacent limiting rings 403. Under the limitation of the limiting ring 403, the position of the limiting plate 401 is limited to provide supporting force for the support rod 2. Then the spring 402 will gradually shrink under pressure, and is limited by the elastic deformation of the spring 402 after compression, while providing support for the support rod 2, further improving the supporting performance of the supporting component.
[0037] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
