[0007] Further:

[0008] The end cover is a circular structure, and an annular groove is arranged on the back side of the end cover.

[0009] The through hole is a tapered hole that is larger on the outside and smaller on the inside.

[0010] The through holes and the gaps are arranged in a continuous manner.

[0011] A splitting groove is arranged on the end cover in alignment with the gap.

[0012] The baffle structure comprises two baffles arranged opposite to each other and respectively arranged on the side edges of the corresponding half of the sealing positioning portion.

[0013] The blocking piece is an arc-shaped piece.

[0014] Compared with the prior art, the utility model has the following advantages:

[0015] The sealing structure of the embedded sleeve is reasonably designed. A baffle is provided on the side of the sealing positioning part on the back of the end cover corresponding to the gap between the two halves of the sealing positioning part, which effectively improves the sealing effect of the embedded sleeve opening; and a splitting groove is provided on the end cover to facilitate the destruction and removal operation.

[0024] The specific implementation of the utility model will be further explained in detail below through the description of embodiments with reference to the accompanying drawings.

[0025] like Figures 1 to 4 As shown, the sealing member of the embedded sleeve is used to be inserted into the end opening of the embedded sleeve 1 for sealing. During construction, the end opening of the embedded sleeve is sealed to prevent concrete from entering the interior of the embedded sleeve.

[0026] The seal includes an end cover 201 and two halves of a seal positioning portion arranged on the back of the end cover. The two halves of the seal positioning portion are a half seal positioning portion 203 and another half seal positioning portion 204 arranged opposite to each other. There is a gap between the two halves of the seal positioning portion to avoid damage to the seal when removing it after embedding is completed; positioning cards 205 are provided on the outer sides of the two halves of the seal positioning portion, and the seal is fixed in the end opening of the embedded sleeve through the positioning cards.

[0027] A through hole 202 is provided on the end cover corresponding to the gap. The through hole and the gap are connected. The through hole is a tapered hole that is larger on the outside and smaller on the inside, which is convenient for the seal breaking operation.

[0028] The end cover 201 is a circular structure, and an annular groove 206 is provided on the back of the end cover; a sealing ring is further provided in the annular groove to improve the sealing effect; a splitting groove 2011 is provided on the end cover to align with the gap to facilitate the destruction of the seal.

[0029] The side of the sealing positioning part corresponds to the gap between the two halves of the sealing positioning part, and a baffle structure is provided for shielding the edge of the gap to improve the sealing performance. That is, the side of the sealing positioning part on the back of the end cover corresponds to the gap between the two halves of the sealing positioning part, and a baffle is provided to effectively improve the sealing effect of the embedded sleeve opening.

[0030] Preferably, the baffle structure is two baffles arranged opposite to each other, which are respectively arranged on the side edges of the corresponding half of the sealing positioning portion; one baffle blocks the opening on one side of the gap, and the other baffle blocks the opening on the other side of the gap, and the sealing concrete enters the inner cavity of the sleeve through the gap, further improving the sealing effect.

[0031] Furthermore, the baffle is an arc-shaped piece, and the baffle and the corresponding sealing positioning portion are an integral injection-molded structure, which has a simple structure and is easy to manufacture.

[0032] The baffle on one half of the sealing positioning part extends to cover the side of the other half of the sealing positioning part, and the gap between the baffle and the side is relatively small, which effectively improves the sealing performance without affecting the easy-to-break performance; further, the side of the other half of the sealing positioning part is an inclined surface, and the baffle on one half of the sealing positioning part is attached to the inclined surface, so the sealing is reliable. The other baffle is set in the same manner.

[0033] The above is only an explanation of the preferred embodiments of the present invention. The above technical features can be arbitrarily combined to form multiple embodiments of the present invention.

[0034] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
