[0002] A through-the-wall combined casing is used for pipeline installation and construction. Pipes that pass through walls must be casingd. If casings are not made, the service life of these pipes will be affected. Generally, the pipes that pass through walls are drainage pipes, gas supply pipes, wire pipes or heating pipes, especially air pipes and drainage pipes. If casings are not made, in the event of a dangerous situation where the water pipes burst, the lives of the residents of the entire house will be threatened. Therefore, the through-the-wall pipes must be installed with casings for everyone's living safety. Traditional casings face the risk of water seepage in harsh environments, are not durable, and have the risk of detachment over time. Therefore, a safe, durable, waterproof, and strong through-the-wall combined casing is needed to solve these problems. Utility Model Content

[0003] The utility model aims to provide a wall-penetrating combined casing to solve the problems in the prior art of high risk of water seepage, low durability and high risk of separation over time.

[0004] The embodiment of the utility model is achieved as follows:

[0005] The utility model embodiment provides a through-the-wall combined sleeve, which includes a self-locking male sleeve and a self-locking female sleeve;

[0006] The self-locking male seat sleeve is tightly embedded in the interior of the self-locking female seat sleeve along the axial direction of the self-locking female seat sleeve;

[0007] A plurality of self-locking annular protrusions are radially arranged on the outer wall of the self-locking male seat sleeve, and a side of the plurality of self-locking annular protrusions close to the self-locking male seat sleeve is fixedly connected to the outer wall of the self-locking male seat sleeve;

[0008] The inner wall of the self-locking female seat sleeve is radially provided with a plurality of self-locking annular grooves, and the plurality of self-locking annular protrusions are all adapted in the grooves of the plurality of self-locking annular grooves.

[0009] When in use, the self-locking male seat sleeve is inserted into the interior of the self-locking female seat sleeve along the axial direction of the self-locking female seat sleeve, and the self-locking annular protrusions are snapped into the self-locking annular grooves to achieve a sealed connection.

[0010] The wall-penetrating combination sleeve disclosed in the present embodiment has a plurality of self-locking annular protrusions which cooperate with the plurality of the above-mentioned self-locking annular grooves, so that the sealing performance of the combination sleeve is improved, thereby making the wall-penetrating combination sleeve have the beneficial effects of corrosion resistance, durability, good heat insulation effect, good fire prevention effect, good flame retardant effect, low risk of water seepage, high durability and not easy to fall off.

[0011] Optionally, a plurality of the self-locking annular protrusions are evenly spaced apart along the axial direction of the self-locking male seat sleeve.

[0012] Such a configuration and arrangement can improve the sealing effect of the combined sleeve.

[0013] Optionally: a plurality of the self-locking annular grooves are evenly spaced apart along the axial direction of the self-locking female seat sleeve.

[0014] Such arrangement makes it easy to adapt to a plurality of the above-mentioned self-locking annular protrusions, thereby achieving sealing.

[0015] Optionally: several of the above-mentioned self-locking annular protrusions have a first inclined surface on one side close to the above-mentioned self-locking female seat sleeve, and several of the above-mentioned self-locking annular grooves have a second inclined surface, and the above-mentioned first inclined surface is adapted to the above-mentioned second inclined surface.

[0016] In this way, the first inclined surface is conducive to the insertion of the plurality of self-locking annular protrusions into the self-locking female seat sleeve, and has a guiding effect. The first inclined surface cooperates with the second inclined surface to increase the contact surface between the plurality of self-locking annular protrusions and the plurality of self-locking annular grooves. Through multi-faceted contact, the sealing between the plurality of self-locking annular protrusions and the plurality of self-locking annular grooves is improved.

[0017] Optionally: one end of the self-locking male seat sleeve away from the self-locking female seat sleeve is fixedly connected to the outer inclined opening of the male seat, and one end of the self-locking female seat sleeve away from the self-locking male seat sleeve is fixedly connected to the outer inclined opening of the female seat;

[0018] The diameters of the external inclined opening of the male seat and the external inclined opening of the female seat are larger than the diameters of the self-locking male seat sleeve and the self-locking female seat sleeve.

[0019] With such arrangement, when the external inclined opening of the male seat and the external inclined opening of the female seat are fixed in the wall, an inward force will be generated, so that the plurality of the self-locking annular protrusions and the plurality of the self-locking annular grooves are more firmly fixed in the wall, and will become more and more firmly with the passage of time, effectively avoiding the problem of traditional sleeves being easily loosened and detached over time.

[0020] Optionally, a silicone rubber glass fiber heat-resistant sleeve is provided inside the self-locking male socket sleeve, and the outer wall of the silicone rubber glass fiber heat-resistant sleeve is tightly fitted to the inner wall of the self-locking male socket sleeve.

[0022] Optionally: the outer wall of the self-locking nut sleeve has a high temperature resistant and anti-corrosion coating layer.

[0023] With such a configuration, the use of a high temperature resistant anti-corrosion coating layer can ensure that the casing surface is not corroded in harsh environments, and due to its film-forming characteristics, the overall wall thickness of the casing is ensured without occupying the space of the internal pipeline of the casing.

[0024] Optionally, the self-locking male socket sleeve and the self-locking female socket sleeve are both galvanized steel pipes.

[0025] In this way, galvanized steel pipe is selected as the main body of the above-mentioned self-locking male socket sleeve and the above-mentioned self-locking female socket sleeve, mainly because the galvanized steel pipe has low cost, high strength and strong plasticity, which can ensure that the overall strength of the sleeve is sufficient and not easy to deform. The galvanized layer of the galvanized steel pipe can effectively prevent the steel pipe from being oxidized and corroded, thereby extending its service life. The galvanized steel pipe retains the high-strength characteristics of ordinary steel pipes, can withstand greater pressure and impact force, and has good plasticity and weldability, which is easy to process and install.

[0026] Optionally: the self-locking male seat sleeve and the external inclined opening of the male seat are formed integrally with each other, and the self-locking female seat sleeve and the external inclined opening of the female seat are formed integrally with each other.

[0027] Such an arrangement can ensure that the self-locking male seat sleeve and the self-locking female seat sleeve are connected to each other without being affected by external forces and falling off, thereby improving the stability of the connection between the self-locking male seat sleeve and the self-locking female seat sleeve.

[0028] Optionally, a plurality of the self-locking annular protrusions and the self-locking male seat sleeve are integrally formed with each other.

[0029] Such an arrangement can improve the overall strength of the plurality of self-locking annular protrusions, prevent them from falling off or being damaged, and thus ensure the sealing performance of the combined sleeve.

[0030] Based on the above description, the wall-penetrating combined sleeve disclosed by the utility model has the beneficial effects of corrosion resistance, durability, good heat insulation effect, good fire prevention effect, good flame retardant effect, low risk of water seepage, high durability and not easy to fall off.
