[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] Example:
[0031] Please see Figure 1-6The prefabricated house with a high-sealing bottom includes a base plate 1, a side plate 2 installed on top of the base plate 1, and a top plate 3 installed on top of the side plate 2. An installation groove 4 is formed on the top of the base plate 1, and a sealing groove 5 and an extrusion groove 6 are formed on the sides of the base plate 1. The installation groove 4, sealing groove 5, and extrusion groove 6 are interconnected. A splicing plate 7, a sealing rubber gasket 9, and an extrusion mechanism 10 are respectively installed inside the installation groove 4, sealing groove 5, and extrusion groove 6. The splicing plate 7 is detachably connected to the base plate 1 via a connecting mechanism 8. The sides of the base plate 1 are relatively sealed. Grooves 12 are provided at the positions of groove 5 and extrusion groove 6, and sealing mechanism 13 is provided in the inner cavity of groove 12. By providing installation groove 4, splicing plate 7 can be snapped together. By providing connecting mechanism 8, splicing plate 7 can be fixed. By providing sealing groove 5 and extrusion groove 6, sealing rubber gasket 9 and extrusion mechanism 10 can be installed, thereby increasing the sealing between base plate 1 and splicing plate 7. By providing groove 12 and sealing mechanism 13, the sealing at sealing rubber gasket 9 and extrusion mechanism 10 can be increased.
[0032] The connecting mechanism 8 includes a threaded groove 81 on the top of the splicing plate 7 and a limiting groove 83 on the side of the base plate 1. The limiting groove 83 extends through the interior of the splicing plate 7. The threaded groove 81 and the limiting groove 83 are interconnected. A limiting strip 84 is slidably sleeved inside the limiting groove 83. A retaining groove 85 is provided at the top of the limiting strip 84 relative to the threaded groove 81. A first bolt 82 is threadedly sleeved inside the threaded groove 81. The bottom of the first bolt 82 extends through the interior of the retaining groove 85. When installing the splicing plate 7, the splicing plate 7 is clamped inside the mounting groove 4. Then, the limiting strip 84 is inserted into the limiting groove 83 and extends through the interior of the splicing plate 7, so that the retaining groove 85 and the threaded groove 81 are on the same vertical line. Then, the first bolt 82 is screwed into the threaded groove 81, extends through the retaining groove 85 and into the base plate 1, thereby completing the fixing of the splicing plate 7.
[0033] It should also be noted that if the area of the prefabricated house is large, the splicing panel 7 can be composed of multiple panels spliced together.
[0034] The bottom of the first bolt 82 penetrates the interior of the base plate 1, and the first bolt 82 and the limiting strip 84 are arranged in a cross shape. With this arrangement, the splicing plate 7 can be fixed in both the horizontal and vertical directions, thereby increasing the stability of the splicing plate 7 after it is fixed.
[0035] In addition, the sealing rubber gasket 9 is convex in shape, and its top fits against the bottom of the splicing plate 7. By setting the sealing rubber gasket 9, the connection between the splicing plate 7 and the base plate 1 can be sealed. The surface of the sealing rubber gasket 9 is covered with a stainless steel sheet, which facilitates the insertion of the sealing rubber gasket 9 into the sealing groove 5.
[0036] Preferably, the extrusion mechanism 10 includes a receiving plate 101 disposed in the inner cavity of the extrusion groove 6, a receiving groove 102 opened on the top of the receiving plate 101, and an extrusion plate 104 slidably connected to the inner wall of the receiving groove 102. A plurality of springs 103 are equidistantly connected to the bottom of the inner cavity of the receiving groove 102. The top of the springs 103 is fixedly connected to the bottom of the extrusion plate 104. A locking mechanism 11 is provided on the receiving plate 101.
[0037] Specifically, after the receiving plate 101 is inserted into the extrusion groove 6, the extrusion plate 104 can move upward under the action of the spring 103's restoring force and extrude the sealing rubber gasket 9, which can further improve the sealing performance at the connection between the splicing plate 7 and the base plate 1. By setting the locking mechanism 11, the extrusion plate 104 can be restricted, making it easier to insert the extrusion mechanism 10 into the extrusion groove 6.
[0038] The locking mechanism 11 includes a connecting plate 111 and two locking plates 112 fixedly connected to one side of the connecting plate 111. The surface of the receiving plate 101 is provided with an insertion groove 113 adapted to the locking plate 112. The bottom of the insertion groove 113 penetrates the interior of the receiving groove 102. The surface of the pressing plate 104 is provided with a locking groove 114 relative to the insertion groove 113. In the initial state, the locking plate 112 is inserted into the interior of the locking groove 114 through the insertion groove 113. At this time, the spring 103 is compressed. When the pressing mechanism 10 is inserted into the pressing groove 6, the locking plate 112 is pulled out from the interior of the insertion groove 113 and the locking groove 114 through the connecting plate 111. Without the restriction of the locking plate 112, under the action of the restoring force of the spring 103, the pressing plate 104 will move upward on the inner wall of the receiving groove 102 and squeeze the sealing rubber gasket 9.
[0039] Preferably, the sealing mechanism 13 includes a sealing plate 131 that is snapped into the inner cavity of the groove 12, and a second bolt 132 threaded onto the sealing plate 131. The sealing plate 131 is detachably connected to the base plate 1 via the second bolt 132. After the splicing plate 7, the sealing rubber gasket 9, and the extrusion mechanism 10 are respectively installed inside the mounting groove 4, the sealing groove 5, and the extrusion groove 6, the sealing plate 131 is snapped into the groove 12 and then fixed by the second bolt 132, which can seal the sealing groove 5 and the extrusion groove 6.
[0040] The sealing plate 131 has an embedded groove 133 on its surface, and a sealing ring 134 is fitted inside the embedded groove 133. By setting the sealing ring 134, the sealing performance at the connection between the sealing mechanism 13 and the base plate 1 can be increased.
[0041] Working principle: The splicing plate 7 can be snapped into place by setting the mounting groove 4. The splicing plate 7 can be fixed by setting the connecting mechanism 8. When fixing, the splicing plate 7 is snapped into the inside of the mounting groove 4. Then, the limiting strip 84 is inserted into the limiting groove 83 and passes through the inside of the splicing plate 7, so that the snap groove 85 and the threaded groove 81 are on the same vertical line. Then, the first bolt 82 is screwed into the threaded groove 81, passes through the snap groove 85 and extends into the base plate 1, thereby completing the fixing of the splicing plate 7.
[0042] Then, the sealing rubber gasket 9 is inserted into the sealing groove 5, and the extrusion mechanism 10 is inserted into the extrusion groove 6. Then, the locking mechanism 11 is removed from the extrusion mechanism 10. At this time, after the restriction of the locking mechanism 11 is removed, under the action of the spring 103, the extrusion plate 104 can move upward and extrude the sealing rubber gasket 9, which can further improve the sealing performance at the connection between the splicing plate 7 and the base plate 1.
[0043] Finally, the sealing plate 131 is inserted into the groove 12 and then fixed by the second bolt 132, which can seal the sealing groove 5 and the extrusion groove 6. By setting the sealing ring 134, the sealing performance at the connection between the sealing mechanism 13 and the base plate 1 can be increased.

[0045] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
