[0001] The utility model relates to the technical field of building water supply and drainage installation and construction, in particular to a narrow space inspection port installation device. Background Art

[0002] During the construction of drainage risers for building sewage and wastewater, it is necessary to set up inspection ports on each floor of the building drainage riser to facilitate inspection and maintenance of the building drainage riser. The inspection port is an open short pipe with a cover plate. The drainage riser can be unblocked by removing the cover plate. The inspection port is generally set at the turns, bifurcations, nodes, near walls, tops, bottoms and easily blocked places of the pipeline, which are prone to problems and maintenance.

[0003] During the installation and construction of building water supply and drainage, the tightening of the drainage inspection port is an important link. However, due to the small space and inconvenient operation, the inspection port of the drainage riser is prone to not being tightened, resulting in leakage of the drainage riser. The leakage of the drainage riser will damage the wall and increase the maintenance cost. Summary of the invention

[0006] The beneficial effect is that the clamping part clamps the cover plate at the inspection port through the sleeve and the clamping block, and the holding rod is rotated so that the connecting rod drives the sleeve to rotate and then opens or tightens the cover plate, thereby improving the tightness of the connection between the cover plate and the inspection port and reducing the probability of sewage in the drainage riser flowing out of the inspection port.

[0007] A further technical solution of the utility model is that one end of the vertical rod facing the connecting rod is threadedly connected to the connecting rod.

[0008] The beneficial effect is that the threaded connection between the vertical pole and the connecting rod makes the vertical pole and the connecting rod detachable, and when the space size at the inspection port is different, the connection between the vertical pole and the connecting rod is disassembled by thread to realize replacement of vertical poles of different heights.

[0009] A further technical solution of the utility model is that one end of the vertical rod away from the connecting rod is fixedly connected to the holding rod.

[0010] The beneficial effect is that through the fixed connection between the vertical pole and the connecting rod, vertical poles and holding rods of different specifications can be mass-produced in the factory, thereby improving their applicability to different space inspection openings.

[0011] A further technical solution of the utility model is that a plurality of anti-sliding blocks are fixedly arranged on the surface of the gripping rod.

[0012] The beneficial effect is that the provision of the anti-sliding block increases the friction between the palm and the gripping rod when the worker grabs the gripping rod for rotation, thereby improving the stability between the palm and the gripping rod.

[0013] A further technical solution of the utility model is that the surfaces of the holding rod, the vertical rod and the connecting rod are all provided with a protective layer.

[0014] The beneficial effect is that by providing a protective layer, such as an anti-corrosion layer, on the surface of the holding rod, the rod column and the connecting rod, the service life of the holding rod, the column and the connecting rod is increased.

[0015] A further technical solution of the utility model is that a scale is arranged outside the sleeve.

[0016] The beneficial effect is that the setting of the scale enables the staff to quickly select the corresponding sleeve for clamping according to the size of the inspection port.

[0017] A further technical solution of the utility model is that a plurality of installation grooves are evenly arranged on the surface of the sleeve, and the clamping blocks are installed in the installation grooves.

[0018] The beneficial effect is that the clamping block can be quickly installed through the setting of the installation groove, and when a certain clamping block falls off, it can be quickly positioned, thereby improving the installation efficiency.

[0019] A further technical solution of the utility model is that a fluorescent layer is provided on the surface of the clamping block.

[0020] The beneficial effect is that, by providing the fluorescent layer, when repairing the inspection port under different light conditions, the fluorescent layer can help the staff to quickly position and clamp the cover plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.

[0027] like Figure 1-4 As shown, a narrow space inspection port installation device includes a rotating part 1 and a clamping part 2, the rotating part 1 is connected to the clamping part 2, the clamping part 2 is used to clamp the inspection port cover plate, and the rotating part 1 is used to rotate the clamping part so that the inspection port cover plate is tightened under the rotation of the clamping part 2.

[0028] Reference Figure 1 and Figure 2 The rotating part 1 includes a holding rod 11, a vertical rod 12 and a connecting rod 13. The holding rod 11 and the connecting rod 13 are arranged in parallel. The vertical rod 12 is vertically installed between the holding rod 11 and the connecting rod 13. The vertical rod 12 is fixedly connected to the holding rod 11 at one end facing the holding rod 11. The vertical rod 12 is prefabricated with a thread at one end away from the holding rod 11. The vertical rod 12 is fixedly connected to the connecting rod 13 at one end away from the holding rod 11 by a thread. The vertical rod 12 and the connecting rod 13 are connected by a thread so that the vertical rod 12 and the holding rod 11 can be prefabricated before construction. The vertical poles 12 of the same height can adapt to the different installation spaces of the inspection ports, reducing the probability that the vertical poles 12 are inappropriate in height due to the small space and need to be remade, thereby affecting work efficiency; a plurality of anti-sliding blocks 3 are fixedly connected to the surface of the gripping rod 11, and the anti-sliding blocks 3 are evenly distributed on the surface of the gripping rod 11. When the staff grasps the gripping rod 11 and rotates it, the anti-sliding blocks 3 increase the friction between the gripping rod 11 and the hand, reducing injuries caused by the gripping rod 11 slipping out of the hand during rotation due to the smooth surface of the gripping rod 11.

[0029] Reference Figure 1The clamping portion 2 includes a sleeve 21 and a plurality of clamping blocks 22 fixedly connected to the sleeve 21. In the present embodiment, the number of the clamping blocks 22 on the sleeve 21 is 3, and the clamping blocks 22 are used to clamp the inspection port cover so as to rotate and tighten the inspection port cover through the rotating portion 1; the connecting rod 13 is fixedly connected to the sleeve 21 on the side away from the vertical rod 12, so that the rotation of the holding rod 11 is transmitted to the sleeve 21 through the connecting rod 13 and then drives the sleeve 21 to rotate, and the sleeve 21 rotates so that the clamping blocks 22 clamp the inspection port cover and rotate to tighten the inspection port cover.

[0030] Reference Figure 2 and Figure 3 In order to increase the service life of the rotating part 1, a protective layer 4 is provided on the surface of the holding rod 11, the vertical rod 12 and the connecting rod 13. The protective layer 4 can be an anti-corrosion layer, an anti-rust layer, etc., so that the holding rod 11, the vertical rod 12 and the connecting rod 13 can be recycled for a long time, reducing the probability of the holding rod 11, the vertical rod 12 and the connecting rod 13 being affected by corrosion.

[0031] Reference Figure 1 A plurality of scales 5 are provided on the surface of the sleeve 21, and the scales 5 are used to indicate the size of the sleeve 21, so that the staff can quickly select the sleeve 21 of the corresponding size according to the size of the inspection port cover plate, thereby reducing the time for selecting the sleeve 21 and improving work efficiency.
