Description

Technical Field

[0001] The utility model relates to the technical field of thermal insulation board connection, in particular to a socket-and-spigot type connection device for building thermal insulation boards. Background Art

[0002] Traditional sandwich insulation panels are composed of two metal panels and insulation filling material between the two metal panels. The connection between adjacent sandwich insulation panels is generally achieved by setting a connecting device on one or both sides and using a flat seam connection. This method has cumbersome installation steps, high cost, and poor air tightness.

[0003] To this end, the utility model with publication number CN217679712U proposes a socket-type connection device for sandwich composite thermal insulation panels. The socket-type connection device for sandwich composite thermal insulation panels comprises a sandwich composite thermal insulation panel body A and a sandwich composite thermal insulation panel body B, and the sandwich composite thermal insulation panel body A and the sandwich composite thermal insulation panel body B are connected by a socket-type movable connection. The socket-type connection device for sandwich composite thermal insulation panels provided by the utility model has a slot near the top inside thereof, which is provided with a cross-section that matches the oblique cross-section of the insertion plate. Therefore, after the insertion plate slides inward, the top rod cap of the insertion rod is pushed by the cross-section of the slot, causing the insertion rod to slide down along the stepped hole and be inserted into the rod hole at the corresponding position. At this time, the spring B is also compressed, so that the locking assembly has a locking effect on the sandwich composite thermal insulation panel body A and the sandwich composite thermal insulation panel body B.

[0004] However, the above-mentioned existing technology still has the following shortcomings when used: the insertion action of the insertion rod is driven by an inclined surface, that is, when the two plates are plugged in, the insertion rod will gradually move axially due to the action of the inclined surface, and then be inserted into the rod hole, thereby realizing the locking connection between the two plates. However, due to the displacement of the two plates moving in opposite directions and the axial displacement of the insertion rod, the insertion rod is in an inclined movement state, which makes it difficult to accurately plug into the rod hole, and further causes the two plates to be loose or shaking after being plugged in.

[0005] To this end, the utility model provides a socket-and-spigot type connection device for a building insulation board. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a socket-type connection device for building insulation boards to solve the problems raised in the above-mentioned background technology. The present invention has the advantage of making the left board and the right board accurately plugged in, and the connection after plugging in is more tight and reliable.

[0007] In order to achieve the above-mentioned purpose, the present invention is implemented through the following technical solutions: a socket-type connection device for a building insulation board, comprising a left plate and a right plate, wherein the docking sides of the left plate and the right plate are respectively provided with a plug-in plate and a slot, and the plug-in plate and the slot are plug-fitted together, and further comprising a pad and a pin shaft, the upper end surface of the plug-in plate is provided with a row of through holes plug-fitted with the pin shaft, one side of the slot is provided with a plug-in hole plug-fitted with one end of the pin shaft, a support plate is fixedly provided on one side of the pad, and a slot is provided on one side of the support plate to engage with the pin shaft, and the other end of the pin shaft is sleeved with a baffle with an outer diameter greater than the width of the slot, a support spring is provided in the plug-in hole, and the support spring applies an elastic thrust to the pin shaft in the direction of the plug-in plate, and a push block close to the rear is provided in the slot.

[0008] Furthermore, the sum of the thicknesses of the backing plate and the inserting plate is equal to the width of the slot.

[0009] Furthermore, the card slot is a U-shaped slot structure.

[0010] Furthermore, a row of docking holes is provided at the bottom of the slot, and a row of plug shafts that are excessively matched with the docking holes are fixedly connected to one side of the plug board.

[0011] Furthermore, an annular groove is provided in the through hole, an external fixing sleeve of the pin shaft is provided with a retaining ring located in the annular groove, and a support spring located on one side of the retaining ring is sleeved on the pin shaft.

[0012] Furthermore, one end of the annular groove extends to the other side of the inserting plate, and the baffle and the pin are screwed together and detachably connected.

[0013] Furthermore, a filling plate located above the supporting plate is fixedly provided on one side of the pad.

[0014] The beneficial effects of the utility model are as follows:

[0015] The utility model provides a pad for lifting the pin shaft, so that the pad can release the limit of the pin shaft on the right side of the left plate groove when the left plate is plugged in, so that the pin shaft can accurately lock the left plate and the right plate after plugging in. Compared with the existing technology, there will be no problem of shaking after connection.

[0016] The utility model arranges a row of docking holes in the slot and then arranges a row of insertion shafts on the insertion plate.

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] See also Figures 1 to 4 The utility model provides a technical solution: a socket-type connection device for building insulation boards, comprising a left board 1 and a right board 2, two insulation boards on the left board 1 and the right board 2 that need to be socket-connected, a plug-in plate 3 and a slot 4 are respectively provided on the butt joint sides of the left board 1 and the right board 2, the plug-in plate 3 and the slot 4 are plug-fitted, that is, the left board 1 and the right board 2 are connected by plugging and fitting together.

[0024] The present technical solution also includes a pad 5 and a pin shaft 6. The upper end surface of the plug plate 3 is provided with a row of through holes 31 that are plugged into the pin shaft 6. One side of the slot 4 is provided with a socket 41 that is plugged into one end of the pin shaft 6. A support plate 51 is fixedly provided on one side of the pad 5. One side of the support plate 51 is provided with a slot 511 that is engaged with the pin shaft 6. The slot 511 is a U-shaped slot structure. The other end of the pin shaft 6 is sleeved with a baffle 7 with an outer diameter greater than the width of the slot 511. A support spring 8 is provided in the socket 41. The support spring 8 applies an elastic thrust to the pin shaft 6 in the direction of the plug plate 3. The support plate 51 limits the baffle 7 so that the other end of the pin shaft 6 is immersed in the through hole 31. When the pad 5 is removed, the other end of the pin shaft 6 will extend out of the through hole 31 under the push of the elastic force, and a push block 42 near the rear is provided in the slot 4. Therefore, in the present technical solution, the pad 5 is fitted onto one side of the plug-in plate 3 and limits the pin 6 to form a structure that is plugged into the slot 4. During the plugging, the push block 42 pushes the support plate 51 out of the baffle 7, thereby releasing the lock on the pin 6. When the pin 6 is relative to the socket 41, it will be directly inserted into the socket 41, thereby realizing a fastened connection between the left plate 1 and the right plate 2.

[0025] Specifically, an annular groove 311 is provided in the through hole 31, and the external fixed sleeve of the pin shaft 6 is provided with a retaining ring 61 located in the annular groove 311. The pin shaft 6 is provided with a support spring 8 located on one side of the retaining ring 61, that is, the support spring 8 located in the annular groove 311 applies an elastic thrust to the pin shaft 6 through the retaining ring 61.

[0026] In this embodiment, the sum of the thicknesses of the backing plate 5 and the inserting plate 3 is equal to the width of the slot 4. This arrangement can eliminate the gap between the slot insert block formed by the backing plate 5 and the inserting plate 3 and the slot 4, thereby preventing shaking.

[0027] In this embodiment, a row of docking holes 43 are provided at the bottom of the slot 4, and a row of plug shafts 32 that are overfitted with the docking holes 43 are fixedly connected to one side of the plug-in board 3. After the left board 1 and the right board 2 are plugged in, the plug shafts 32 will be inserted into the docking holes 43 accordingly. This arrangement can improve the bending strength of the plug-in point between the left board 1 and the right board 2.

[0028] In this embodiment, one end of the annular groove 311 extends to the other side of the insert plate 3, and the baffle 7 and the pin shaft 6 are screwed together and detachably connected. This arrangement greatly reduces the difficulty of assembling the pin shaft 6, the support spring 8 and the annular groove 311, and has the advantage of being more convenient to manufacture.

[0029] In this embodiment, a filling plate 52 located above the support plate 51 is fixedly provided on one side of the pad 5. The function of the filling plate 52 is to fill part of the space in the slot 4, thereby improving the tightness of the connection between the left plate 1 and the right plate 2, and effectively avoiding the problem of stress concentration at the inserting plate 3.

[0030] Working principle: When in use, the inserting plate 3 and the pad 5 are directly inserted into the slot 4, and then as the plugging proceeds, when the pushing block 42 contacts the front side of the supporting plate 51, the supporting plate 51 will be pushed and dislocated relative to the inserting plate 3. At this time, the supporting plate 51 will move backward relative to the inserting plate 3. When the supporting plate 51 is separated from the baffle 7, the pin 6 moves under the elastic force of the support spring 8, and the bottom of the pin 6 will press against the inner wall of the slot 4. As the inserting plate 3 continues to advance, the pin 6 will be directly inserted into the socket 41 when passing through the socket 41. At this time, the left plate 1 and the right plate 2 are in a tightly plugged state.

[0031] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
