[0040] Insert 2; the insert 2 is connected to the outer side of the inner corner plate 1; one side of the insert 2 is provided with a one-way tooth;

[0041] External angle plate 3; the external angle plate 3 is a plate formed by combining two plates to form a certain angle; the inner side of the external angle plate 3 abuts against the inner walls of the two wall panels; the angle formed by the external angle plate 3 and the internal angle plate 1 matches;

[0042] The locking strip 4 is connected to the inner side of the outer corner plate 3; the locking strip 4 is provided with a slot 41 on the side close to the insertion strip 2; the slot wall of the slot 41 is penetrated by a card slot 42; the card block 43 is slidably connected in the card slot 42; the card block 43 is provided with a No. 1 inclined surface 431 at one end close to the slot 41; the No. 1 inclined surface 431 of the card block 43 will slide along the card slot 42 under the pressure of the insertion strip 2; the slot wall of the card slot 42 is provided with a reset slot 421; the reset plate 422 is slidably connected in the reset slot 421; the reset plate 422 is fixedly connected to the card block 43; the reset plate 422 and the slot wall of the reset slot 421 are connected by a reset spring 423; the insertion strip 2 and the slot 41 are locked by the card block 43;

[0043] During operation, the connection between the wall panels of the prefabricated house is an important part of the assembly construction of the prefabricated house. In the existing technology, the connection between the wall panels is connected by bolts through the wall corner columns. The connection process is time-consuming and labor-intensive, and each wall corner column can only be used for wall panels of matching thickness, which has poor applicability.

[0044] Therefore, after the present invention staff prefabricates the connecting mechanism and the wall panels in the factory, they move the wall panels and the connecting mechanism to the construction site, first erect the two wall panels at a certain angle, then place the inner angle plate 1 on the inner side of the angle formed by the two wall panels, and when the inner angle plate 1 moves, it will drive the inserting strip 2 to be inserted into the gap formed by the two wall panels, and then place the outer angle plate 3 on the outer side of the angle formed by the two wall panels, and when the outer angle plate 3 moves, it will drive the locking strip 4 to move synchronously, so that the end of the inserting strip 2 away from the inner angle plate 1 moves along the gap formed by the two wall panels. The slot 41 of the lock bar 4 is inserted into the slot 41, and as the inserting strip 2 is inserted along the slot 41, the inserting strip 2 will squeeze the No. 1 inclined surface 431 of the card block 43 in the slot 41, so that the card block 43 will slide along the card slot 42 after being squeezed. During the movement of the card block 43 along the card slot 42 away from the slot 41, the reset plate 422 will be driven to squeeze the reset spring 423 to complete the power storage process. Subsequently, after the end of the card block 43 with the No. 1 inclined surface 431 is inserted into the one-way tooth on the inserting strip 2, the reset spring 423 will push the reset plate 4 The outer corner plate 3 and the inner corner plate 1 are connected to each other, so that the outer corner plate 3 and the inner corner plate 1 are connected. After the connection is completed, in order to avoid unevenness between the inner side of the wall panel and the inner corner panel 1, and the outer side of the wall panel and the outer corner panel 3, surface treatment can be performed on the wall panel and the connection mechanism, such as hanging a mesh, applying putty, and painting. Alternatively, the position where the wall panel is clamped by the inner corner panel 1 and the outer corner panel 3 can be recessed so that the inner corner panel 1 and the outer corner panel 3 are embedded to achieve surface flatness. After the inner corner panel 1 and the outer corner panel 3 clamp the two wall panels, building materials such as thermal insulation cotton, concrete, and prefabricated reinforcement columns can be filled between the inner corner panel 1 and the outer corner panel 3.

[0045] The present invention locks the connection between the two wall panels by plugging the inner corner panel 1 and the outer corner panel 3, thereby realizing a quick connection at the corner of the assembled house. At the same time, the present invention is also suitable for wall panels of different thicknesses and has the characteristics of simple operation and convenient use.

[0046] As an embodiment of the present invention, the outer side of the inner corner panel 1 is fixedly connected to an inner strip 11; the inner strip 11 is provided near the corner of the inner corner panel 1; a first slide groove 12 is provided on the side of the inner strip 11 away from the inner corner panel 1 and passes through the inner corner panel 1; the end of the insert 2 is in an inverted T-shape and is slidably connected to the first slide groove 12;

[0047] The inner side of the outer corner plate 3 is fixedly connected to the outer strip 31; the outer strip 31 is provided near the corner of the outer corner plate 3; a second slide groove 32 is provided on the side of the outer strip 31 away from the outer corner plate 3 and runs through the outer strip 31 from top to bottom; the end of the lock bar 4 away from the slot 41 is provided with an inverted T-shape and is slidably connected to the second slide groove 32;

[0048] During operation, this embodiment can prefabricate the opening angles of the inner corner panels 1 and the outer corner panels 3 in a unified manner, so that the inner corner panels 1 and the outer corner panels 3 with the same angles can be matched according to the angles between the wall panels. After the types of the required inner corner panels 1 and the outer corner panels 3 are selected, the insert 2 will slide into the opening of the No. 1 slide groove 12 and slide along the up and down directions of the No. 1 slide groove 12 to adjust the position where the inner corner panel 1 needs to be fixed, locked or connected. Since the insert 2 has a certain friction with the No. 1 slide groove 12, the insert 2 can also slide along the No. 1 slide groove 12 after sliding. Stay at any position of the No. 1 slide groove 12, then slide one end of the locking bar 4 into the No. 2 slide groove 32 according to the corresponding position of the insertion strip 2, and then plug and assemble the inner angle panel 1 and the outer angle panel 3. After the insertion strip 2 is inserted into the slot 41 on the locking bar 4, the staff can also use a long rod or other object to poke the locking bar 4 and the insertion strip 2 above the space between the inner angle panel 1 and the outer angle panel 3, so that the locking bar 4 slides downward along the No. 2 slide groove 32, and the insertion strip 2 slides downward along the No. 1 slide groove 12, so that the position can be adjusted after the insertion strip 2 is inserted into the locking bar 4.

[0049] As an embodiment of the present invention, a rectangular groove 44 is provided at one end of the lock bar 4 away from the slot 41; a rectangular bar 45 is slidably connected in the rectangular groove 44; the rectangular bar 45 is connected to the bottom of the rectangular groove 44 by a No. 1 spring 46; a trapezoidal groove 451 is provided at the upper end of the rectangular bar 45; the groove wall of the trapezoidal groove 451 close to the No. 1 spring 46 is a No. 2 inclined surface; a pressing groove 47 is provided at the upper end of the lock bar 4; the pressing groove 47 is communicated with the rectangular groove 44 and is located directly above the trapezoidal groove 451; a pressing block 48 is slidably connected in the pressing groove 47; a No. 3 inclined surface is provided at one end of the pressing block 48 close to the trapezoidal groove 451; an inclined surface transmission is performed between the pressing block 48 and the trapezoidal groove 451;

[0050] During operation, before the end of the lock bar 4 away from the slot 41 slides into the No. 2 slide groove 32 from the opening of the No. 2 slide groove 32, first press the pressing block 48 so that the pressing block 48 moves along the pressing groove 47 toward the rectangular groove 44. After the pressing block 48 is pressed, the No. 3 inclined surface squeezes the No. 2 inclined surface, so that after the No. 2 inclined surface is squeezed, the rectangular bar 45 is squeezed and slides along the rectangular groove 44 and approaches the bottom of the rectangular groove 44, so that the No. 1 spring 46 is squeezed and compressed by the rectangular bar 45, and after sliding, the rectangular bar 45 changes from a state of extending out of the rectangular groove 44 to a state of retracting into the rectangular groove 44. Then, when the rectangular bar 45 is retracted into the rectangular groove 44, one end of the lock bar 4 slides into the No. 2 slide groove. 32 and adjusted to the desired position, release the squeeze on the pressing block 48, and the No. 1 spring 46 will push the rectangular bar 45 to return to its original position, so that the rectangular bar 45 is pressed against the groove wall of the No. 2 slide groove 32 by the No. 1 spring 46, increasing the friction between one end of the lock bar 4 and the No. 2 slide groove 32, so that the lock bar 4 will not be relatively displaced with the No. 2 slide groove 32 even when the wall panel and the connecting mechanism shake, thereby improving the stability of the lock bar 4 after the connection mechanism is installed. The insertion strip 2 is inserted into the slot 41 in the lock bar 4, so the lock bar 4 is stable and the insertion strip 2 is stable; in this embodiment, if the position of the lock bar 4 in the No. 2 slide groove 32 needs to be changed after the connection mechanism is installed, the pressing block 48 needs to be pressed again.

[0052] During operation, the inner angle plate 1 and the outer angle plate 3 can be installed in a section-by-section manner, that is, the height of the inner angle plate 1 and the outer angle plate 3 can be a combination of upper and lower plug-in connections, that is, after one of the inner angle plates 1 is plugged in with the outer angle plate 3 with the locking strip 4 through the insertion strip 2, the new inner angle plate 1 is moved to the upper end of the original inner angle plate 1, so that the second notch 14 on the new inner angle plate 1 is embedded in the first notch 13 on the original inner angle plate 1. At the same time, after the new outer angle plate 3 and the new locking strip 4 are located above the original outer angle plate 3, the new outer angle plate 3 drives the locking strip 4 close to the insertion strip 2 for plug-in connection. In the process of the new outer angle plate 3 approaching the new inner angle plate 1, the fourth notch 34 on the new outer angle plate 3 It is slowly moved and embedded into the No. 3 groove 33 on the original outer angle plate 3, that is, the upper and lower inner angle plates 1 or outer angle plates 3 are stacked together to increase the height of the inner angle plate 1 or outer angle plate 3. By setting limits on the positions of No. 1 groove 13, No. 2 groove 14, No. 3 groove 33 and No. 4 groove 34, even if water flows on the wall, the water will flow from the upper inner angle plate 1 or outer angle plate 3 to the lower inner angle plate 1 or outer angle plate 3, thereby achieving a certain water-blocking purpose. Moreover, the height direction of the inner angle plate 1 and the outer angle plate 3 is spliced ​​in a more convenient transportation manner, and can also be temporarily adjusted according to construction requirements, which greatly improves the flexibility of prefabricated construction.

The end of the insert 2 away from the inner corner panel 1 is controlled to be inserted along the slot 41 of the locking strip 4. The return spring 423 cooperates with the clamping block 43 to lock the insert 2 in the slot 41.

[0062] S4: Finally, the remaining inner corner panels 1 and outer corner panels 3 are plugged into the inner and outer sides of the wall panels according to the plug-in method of step S3, and during the plug-in process, the second notch 14 of the previous inner corner panel 1 is embedded in the first notch 13 of the next inner corner panel 1, and during the plug-in process, the fourth notch 34 of the previous outer corner panel 3 is embedded in the third notch 33 of the next outer corner panel 3, thereby realizing the connection between the upper and lower inner corner panels 1 and outer corner panels 3, that is, realizing the connection at the corner of the entire prefabricated house.

[0063] The specific workflow is as follows:

[0064] After the workers prefabricate the connecting mechanism and the wall panels in the factory, they move the wall panels and the connecting mechanism to the construction site, first erect the two wall panels at a certain angle, then place the inner angle panel 1 on the inner side of the angle formed by the two wall panels, and when the inner angle panel 1 moves, it will drive the inserting strip 2 to be inserted into the gap formed by the two wall panels, and then place the outer angle panel 3 on the outer side of the angle formed by the two wall panels, and when the outer angle panel 3 moves, it will drive the locking strip 4 to move synchronously, so that the end of the inserting strip 2 away from the inner angle panel 1 is inserted along the slot 41 of the locking strip 4, and as the inserting strip 2 is inserted along the slot 41, the inserting strip 2 will squeeze the first inclined surface 431 of the card block 43 in the slot 41, so that after the card block 43 is squeezed, it will move along the card block The slot 42 slides, and the block 43 moves along the slot 42 away from the slot 41, which drives the reset plate 422 to squeeze the reset spring 423 to complete the force accumulation process. Then, after the end of the block 43 with the No. 1 inclined surface 431 is inserted into the one-way tooth on the insertion strip 2, the reset spring 423 pushes the reset plate 422 and the block 43 to slide along the slot 42, thereby locking the insertion strip 2 into the slot 41. During the insertion of the insertion strip 2 along the slot 41, the outer corner plate 3 approaches the inner corner plate 1, thereby making the gap between the outer corner plate 3 and the inner corner plate 1 smaller and smaller, until the outer corner plate 3 and the inner corner plate 1 clamp the two wall panels, thereby connecting the corners of the two wall panels, that is, realizing the connection of the corners of the prefabricated house.

[0065] After selecting the types of the required inner angle plate 1 and outer angle plate 3, the inserting strip 2 will slide into the opening of the No. 1 slide groove 12 and slide along the up and down direction of the No. 1 slide groove 12 to adjust the position where the inner angle plate 1 needs to be fixed, locked or connected. Since the inserting strip 2 and the No. 1 slide groove 12 have a certain friction, the inserting strip 2 can stay at any position of the No. 1 slide groove 12 after sliding along the No. 1 slide groove 12. Then, one end of the locking strip 4 is slid into the No. 2 slide groove 32 according to the corresponding position of the inserting strip 2, and then the inner angle plate 1 and the outer angle plate 3 are plugged and assembled; before the end of the locking strip 4 away from the slot 41 slides into the No. 2 slide groove 32 from the opening of the No. 2 slide groove 32, press the pressing block 48 first so that the pressing block 48 moves along the pressing groove 47 When the locking bar 45 is in the state of extending out of the rectangular groove 44, it changes into a state of retracting into the rectangular groove 44. Then, when the rectangular groove 45 is retracted into the rectangular groove 44, one end of the locking bar 4 is slid into the No. 2 sliding groove 32. After adjusting to the desired position, the pressing block 48 is released, and the No. 1 spring 46 pushes the rectangular groove 45 to return to its original position, so that the rectangular groove 45 is pressed against the wall of the No. 2 sliding groove 32 by the No. 1 spring 46.

[0066] When the new outer corner panel 3 is close to the new inner corner panel 1, the fourth notch 34 on the new outer corner panel 3 is slowly moved and inserted into the third notch 33 on the original outer corner panel 3, thus completing the purpose of stacking the upper and lower inner corner panels 1 or outer corner panels 3 to raise the height of the inner corner panel 1 or outer corner panel 3;

[0067] In the process of the insert 2 sliding along the slot 41, the insert 2 will squeeze the gas inside the slot 41 along the No. 1 hole 35 and the No. 2 hole 15. At the same time, the insert 2 will drive the spike 21 to squeeze the membrane capsule 5 in the slot 41. The membrane capsule 5 is pierced by the spike 21 and then ruptures. Then the glue 51 inside the membrane capsule 5 flows out after the membrane capsule 5 ruptures. As the insert 2 continues to move in the slot 41, the insert 2 will squeeze the glue 51 in the slot 41, so that part of the glue 51 is discharged along the No. 1 hole 35 into the inner side of the outer corner plate 3 and between the wall panels. At the same time, part of the glue 51 is also discharged along the No. 2 hole 15 into the outer side of the inner corner plate 1 and between the wall panels. The glue 51 discharged from the No. 1 hole 35 will flow from top to bottom along the No. 1 overflow groove 36, so that the No. 1 overflow groove 36 is smeared with glue 51, so that the outer corner plate 3 can be bonded to the wall panel in the vertical direction through the glue 51. As the No. 1 overflow groove 36 flows, the No. 1 overflow groove 36 will flow to the connection between the two outer corner plates 3. Since the height of the No. 4 slot 34 is greater than the height of the No. 3 slot 33, the glue 51 will flow into the L-shaped gap formed by the two outer corner plates 3. Similarly, the glue 51 discharged from the No. 2 hole 15 flows into the No. 2 overflow groove 16, and also flows into the L-shaped gap formed by the two inner corner plates 1.
