DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] In order to make the purpose and advantages of the utility model clearer, the following examples are used to specifically illustrate the utility model. It should be understood that the following text only describes one or several specific implementation manners of the utility model, and does not strictly limit the specific protection scope claimed by the utility model.

[0020] Such as Figures 1-3As shown in the figure, a rubber protective sleeve includes a split outer protective sleeve 1 and an integral rubber inner lining sleeve 2. The rubber inner lining sleeve 2 is fixedly sleeved outside the well ring, and the outer protective sleeve 1 is arranged outside the rubber inner lining sleeve 2. The outer protective sleeve 1 includes a connecting disc 11 and a central sleeve 12. There are two connecting discs 11, which are respectively arranged at the top end and the bottom end of the central sleeve 12. The central sleeve 12 is snap-connected between the two outer protective sleeves 1. The central sleeve 12 includes a number of assembled single tiles 13 distributed in a circular array. Adjacent two assembled single tiles 13 are snap-connected. The materials of the connecting disc 11 and the assembled single tiles 13 are hard rubber, and the material of the rubber inner lining sleeve 2 is flexible rubber.

[0021] According to the above structure, the rubber inner lining sleeve 2 is sleeved on the outer wall of the well ring. When installing the rubber inner lining sleeve 2, glue is applied to the inner wall of the rubber inner lining sleeve 2, so that the rubber inner lining sleeve 2 is fixedly connected to the well ring. The rubber inner lining sleeve 2 plays a role in waterproofing, isolating the moisture in the soil from infiltrating into the well ring and slowing down the corrosion of the well ring. After the rubber inner lining sleeve 2 is installed, one of the connecting discs 11 is bonded to one end of the well ring, and then a number of assembled single tiles 13 are assembled in sequence to form a central sleeve 12 attached to the outer wall of the rubber inner lining sleeve 2 to protect the well ring and the rubber inner lining sleeve 2 from being damaged by impact.

[0022] As Figure 3 and 4 shown in the figure, the connecting disc 11 includes a disc 111. One end of the disc 111 is integrally provided with an inner cylinder 112, and the middle part of one end of the disc 111 is integrally connected with a connecting flange 113. The assembled single tile 13 includes a rubber tile 131. The rubber tile 131 is arc-shaped, and the central angle of the rubber tile 131 is 30° - 60°. One side of the rubber tile 131 is provided with an extension plate 132, and the other side of the rubber tile 131 is provided with a docking groove 133 that matches the extension plate 132. One side of the docking groove 133 is fixedly connected with a triangular strip 136, and one side of the extension plate 132 is provided with a triangular groove 137 that matches the triangular strip 136.

[0023] According to the above structure, during assembly, the inner cylinder 112 is inserted into the inside of the well ring, the disc 111 is attached to the end of the rubber inner lining sleeve 2 with glue, and then the bottom ends of a number of rubber tiles 131 are inserted into the top end of the disc 111 in sequence. When adjacent two rubber tiles 131 are assembled, the extension plate 132 on one rubber tile 131 is inserted into the docking groove 133 on the other rubber tile 131. During the insertion process, the triangular strip 136 slides into the corresponding triangular groove 137, improving the sealing performance between adjacent two rubber tiles 131. When the central sleeve 12 is assembled, the other connecting disc 11 is buckled on the top end of the central sleeve 12 and is bonded to the top end of the rubber inner lining sleeve 2 with glue.

[0024] AsFigure 3 and 4 As shown in Figure 3 and 4 , connection grooves 134 are provided at both the top and bottom of the rubber tile 131. The connection grooves 134 are engaged with the corresponding connection flanges 113. A protrusion 135 is fixedly connected inside the connection groove 134. One end of the connection flange 113 is provided with a card slot 114 that cooperates with the protrusion 135. There are several card slots 114, and the several card slots 114 are equidistantly distributed.

[0025] According to the above structure, when the rubber tile 131 is connected to the connection disk 11, the connection groove 134 is stuck on the connection flange 113, and the protrusion 135 is stuck inside the corresponding card slot 114, improving the connection stability between the rubber tile 131 and the connection disk 11 and preventing the assembled single tile 13 from moving.

[0026] The working principle of the present utility model is as follows: The rubber inner lining sleeve 2 is sleeved on the outer wall of the well ring. When installing the rubber inner lining sleeve 2, glue is applied to the inner wall of the rubber inner lining sleeve 2, so that the rubber inner lining sleeve 2 is fixedly connected to the well ring. The rubber inner lining sleeve 2 plays a waterproof role, isolating the moisture in the soil from entering the well ring and slowing down the corrosion of the well ring. After the rubber inner lining sleeve 2 is installed, one of the connection disks 11 is bonded to one end of the well ring, and then several assembled single tiles 13 are sequentially assembled to form a central sleeve 12 attached to the outer wall of the rubber inner lining sleeve 2 to protect the well ring and the rubber inner lining sleeve 2 from being damaged by impact. During assembly, the inner cylinder 112 is inserted into the well ring, the disk 111 is attached to the end of the rubber inner lining sleeve 2 by glue, and then the bottoms of several rubber tiles 131 are sequentially inserted into the top of the disk 111. When adjacent two rubber tiles 131 are assembled, the extension plate 132 on one rubber tile 131 is inserted into the docking groove 133 on the other rubber tile 131. During the insertion process, the triangular strip 136 slides into the corresponding triangular groove 137, improving the connection tightness between adjacent two rubber tiles 131. When the central sleeve 12 is assembled, the other connection disk 11 is buckled on the top of the central sleeve 12 and bonded to the top of the rubber inner lining sleeve 2 by glue. When the rubber tile 131 is connected to the connection disk 11, the connection groove 134 is stuck on the connection flange 113, and the protrusion 135 is stuck inside the corresponding card slot 114, improving the connection stability between the rubber tile 131 and the connection disk 11 and preventing the assembled single tile 13 from moving.

[0027] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and retouches can be made, and these improvements and retouches should also be regarded as the protection scope of the present utility model. The structures, devices, and operation methods not specifically described and explained in the present utility model are implemented according to the conventional means in the art without special instructions and limitations.
