DETAILED DESCRIPTION

[0015] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.

[0016] like Figure 1-3As shown, a load-bearing structure of an underground drainage pipe of a municipal building comprises a connecting cavity 1, a connecting end 2 is arranged at the lower end of the connecting cavity 1, a through hole is opened on the connecting end 2, a mounting groove 3 is arranged at the upper end of the connecting cavity 1, a double-threaded screw 4 is rotatably connected inside the mounting groove 3, an adjusting wheel 5 is arranged at one end of the double-threaded screw 4, two fixing blocks 6 are symmetrically arranged inside the mounting groove 3, the fixing blocks 6 are threadedly connected to the double-threaded screw 4, the upper surfaces of the two fixing blocks 6 are both provided with supporting members 7, the upper surfaces of the supporting members 7 are provided with arc grooves, the inside of the arc grooves is provided with a first cushion layer 8, mounting seats 9 are respectively arranged at both ends of the mounting groove 3, locking parts are arranged on the mounting seats 9, and locking parts are arranged on the locking parts. The part includes a shell 10, which is rotatably connected to the mounting seat 9. A through groove is provided on the shell 10, and also includes a latch 11 arranged inside the through groove, the latch 11 is rotatably connected to the through groove, a connecting rod 12 is hinged on one side of the latch 11, one end of the connecting rod 12 passes through the shell 10, a spring 13 is sleeved on the connecting rod 12, the spring 13 is located inside the through groove, a fixing plate 14 is provided on the connecting rod 12, and the fixing plate 14 is located outside the shell 10, and also includes a bendable steel belt 15, and connecting members 16 are respectively provided at both ends of the steel belt 15, and an insertion rod 17 is provided at one end of the connecting member 16, and a rack 18 matching the latch 11 is provided on the outer surface of the insertion rod 17.

[0017] The connecting cavity 1 passes through the through hole on the connecting end 2, and is fixed to the ground of the underground pipe gallery by bolts. By controlling the forward and reverse rotation of the adjusting wheel 5, the distance between the two supporting members 7 can be controlled. Specifically, the two fixing blocks 6 are respectively threadedly connected to the two ends of the double-threaded screw 4. When the adjusting wheel 5 rotates clockwise, the distance between the two fixing blocks 6 is shortened. When the adjusting wheel 5 rotates counterclockwise, the distance between the two fixing blocks 6 increases. The distance between the two supporting members 7 can be controlled by the fixing blocks 6. When the drainage pipe 23 is placed on the installation groove 3, the distance between the two supporting members 7 is first controlled so that the drainage pipe 23 can directly contact the installation groove 3. At the same time, the distance between the supporting members 7 on both sides of the drainage pipe 23 and the drainage pipe 23 is small, thereby reducing the amplitude of the left and right movement of the drainage pipe 23. After the initial placement of the drainage pipe 23 is completed, the steel belt 15 is placed on the outer surface of the drainage pipe 23. The steel belt 15 is bendable, and the connecting member 16 can be a chain. , wire rope, hemp rope, etc., and then the rod 17 passes through the housing 10. When the rack 18 follows the rod 17 to pass through the housing 10, the rack 18 continuously squeezes the spring 13 through the latch teeth 11, so that the rack 18 and the rod 17 can pass through the housing 10 normally. However, when the rod 17 is pulled out in the opposite direction, the spring 13 pushes the latch teeth 11 toward the rack 18, so that the rack 18 abuts against the latch teeth 11, and the rod 17 cannot be pulled out. At this time, it is necessary to pull out the connecting rod 12 outward to compress the spring 13 again, so that The rack 18 and the plug rod 17 can be pulled out from the shell 10. After the racks 18 on the plug rods 17 at both ends of the steel belt 15 are in contact with the latch teeth 11 in the shell 10, the adjusting wheel 5 is rotated clockwise, and then the two fixing blocks 6 are driven to approach each other by the double-threaded screw 4, so that the support member 7 and the first cushion layer 8 squeeze the drainage pipe 23, so that the drainage pipe 23 is increasingly tightened with the first cushion layer 8 and the steel belt 15, thereby facilitating the fixation of the drainage pipe 23.

[0018] The fixing plate 14 is used to limit the extension range of the spring 13 to prevent the latching tooth 11 from failing to cooperate with the rack 18 in the housing 10 .

[0019] Furthermore, a second cushion layer 19 is provided on the inner surface of the steel belt 15, and bending portions are provided at both ends of the steel belt 15. Both ends of the second cushion layer 19 are respectively abutted against the bending portions at both ends of the steel belt 15. The first cushion layer 8 and the second cushion layer 19 are both made of rubber material. Both the first cushion layer 8 and the second cushion layer 19 can increase the friction between the drainage pipe 23 and protect the outer surface of the drainage pipe 23. The steel belt 15 and the second cushion layer 19 are connected by glue, and the existence of the bending portion facilitates the positioning and installation of the second cushion layer 19.

[0020] Furthermore, a part of the outer surface of the steel belt 15 is provided with a notch 20 , and the notch 20 is used to reduce the mass of the steel belt 15 and improve the convenience in use.

[0021] Furthermore, a side plate 21 is provided at one end of the connecting rod 12 , and the movement of the connecting rod 12 is conveniently controlled by the side plate 21 .

[0022] Furthermore, a positioning groove 22 is provided on the upper surface of the installation groove 3 . The positioning groove 22 is located in the middle of the installation groove 3 , so as to facilitate the stable placement of the drainage pipe 23 in the middle of the installation groove 3 .

[0023] The device can fix drainage pipes 23 of different diameters by means of the bendable steel belt 15 and the connector 16, thereby improving the convenience of use. The coordination between the rack 18 on the plug rod 17 and the locking portion can improve the installation and fixing efficiency of the steel belt 15. Meanwhile, by controlling the two support members 7 to approach each other, the drainage pipe 23 can be further clamped, resulting in a good fixing effect on the drainage pipe 23 and convenient use.

[0024] In the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
