Description

Technical Field

[0001] This utility model relates to the field of structural connection technology, specifically to a connection limiting tenon device. Background Technology

[0002] Structural connections establish a constraint relationship between two structures, such as hinges and fixed connections. However, in special cases, the two structures with this constraint relationship may experience slight displacement due to temperature changes or vibrations. In such cases, if hinges and fixed connections are used to constrain the two structures, the displacement cannot be released, affecting the lifespan of the structures. Therefore, it is urgent to design a connection limiting latch device to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to provide a connecting and limiting latch device to address the aforementioned shortcomings in the prior art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A connecting and limiting tenon device includes a first structure and a second structure. A first groove box is fixed inside the first structure, and a second groove box is fixed inside the second structure. A first channel is provided inside the first groove box, and a second channel is provided inside the second groove box. A connecting tenon is fixed inside the first channel, and one end of the connecting tenon extends into the second channel. A sealing groove is provided inside the second channel, and a sealing ring is provided inside the sealing groove. The sealing ring is fitted onto the outside of the connecting tenon.

[0006] Furthermore, the tops of both the first and second tanks are bolted with cover plates, and the outer walls of the first tank are welded with connecting ribs, which are embedded inside the structure.

[0007] Furthermore, the connecting tenon includes a fixed end and a movable end, and a transition section is integrally formed between the fixed end and the movable end.

[0008] Furthermore, both inner walls of the first channel are provided with mating grooves, and mating blocks are provided inside the mating grooves. A limiting post is integrally formed on one outer wall of the mating block, and a limiting groove is provided on the outer wall of the fixed end. The limiting post extends into the interior of the limiting groove.

[0009] Furthermore, the cross-section of the fixed end is circular.

[0010] Furthermore, the cross-section of the fixed end is square.

[0011] In the above technical solution, the connecting limiting tenon device provided by this utility model has the following advantages: one end of the connecting tenon is fixed inside the first groove box, and the other end of the connecting tenon is movably inserted into the second groove box, so that the first structure and the second structure can slide along the axial direction of the connecting tenon, thereby achieving the effect of releasing the displacement deformation between the first structure and the second structure; by fixing the sealing ring inside the sealing groove, the dust attached to the outer wall of the movable end of the connecting tenon is not easy to enter the interior of the second groove, thereby making the connecting tenon more reliable in use.

Detailed Implementation

[0020] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings 1-5.

[0021] This utility model provides a connecting and limiting tenon device, including structure one 1 and structure two 2. Structure one 1 has a groove box one 3 fixed inside, and structure two 2 has a groove box two 4 fixed inside. Groove one 3 has a groove one 17 inside, and groove two 4 has a groove two 18 inside. Connecting tenon 7 is fixed inside groove one 17. One end of connecting tenon 7 extends into the inside of groove two 18. Sealing groove 11 is provided inside groove two 18. Sealing ring 12 is provided inside sealing groove 11. Sealing ring 12 is sleeved on the outside of connecting tenon 7.

[0022] Specifically, in this embodiment, there are two structural parts: Structure 1 and Structure 2. Structure 1 and Structure 2 are two structural parts that need to be constrained. Structure 1 has a groove box 3 fixed inside, and Structure 2 has a groove box 4 fixed inside. Groove 3 has a channel 17 inside, and groove box 4 has a channel 18 inside. A connecting tenon 7 is fixed inside groove 17, with one end of the connecting tenon 7 extending into groove 18. The depth of groove 18 is greater than the length of the connecting tenon 7, allowing the connecting tenon 7 to be properly positioned within groove 18. The interior of channel 18 moves along the axial direction. A sealing groove 11 is provided inside channel 18, and a sealing ring 12 is provided inside the sealing groove 11. The sealing ring 12 is sleeved on the outside of the connecting tenon 7. The connecting tenon 7 includes a fixed end 8 and a movable end 10. A transition section 9 is integrally formed between the fixed end 8 and the movable end 10. It is fixed inside the sealing groove 11 by the sealing ring 12, so that dust attached to the outer wall of the movable end 10 of the connecting tenon 7 is not easy to enter the interior of channel 18, thereby making the connecting tenon 7 more reliable in use.

[0023] The present invention provides a connecting limiting tenon device, which fixes one end of the connecting tenon 7 inside the slot box 3 and allows the other end of the connecting tenon 7 to be movably inserted into the slot box 4, so that structure 1 and structure 2 can slide along the axial direction of the connecting tenon 7, thereby achieving the effect of releasing the displacement deformation between structure 1 and structure 2.

[0024] In another embodiment of this utility model, the tops of both the first trough 3 and the second trough 4 are bolted to a cover plate 5, which can be disassembled to facilitate the replacement and maintenance of the connecting tenon 7. The outer walls of the first trough 3 are welded with connecting ribs 6, which are embedded inside the structure 1. During the casting of the structure 1, the connecting ribs 6 embedded inside make the first trough 3 more firmly fixed to the structure 1. The second trough 4 and the second structure 2 are fixed in the same way. Both sides of the inner walls of the first trough 17 have mating grooves 13, and mating blocks 14 are provided inside the mating grooves 13. One side of the outer wall of the mating block 14 is integrally formed with a limiting post 15. The outer wall of the fixed end 8 is provided with a limiting groove 16, and the limiting post 15 extends into the limiting groove 16. The limiting post 15 engages with the limiting groove 16 of the connecting tenon 7, thereby limiting the connection between the connecting tenon 7 and the first trough 3. The fixed end 8 has a circular cross-section. Figure 4 As shown, when the fixed end 8 is cylindrical, the channel 17 is also circular, and the inner wall of the channel 17 and the bottom of the cover plate 5 are in contact with the outer wall of the fixed end 8, so that the fixed end 8 cannot move in any direction inside the channel 17.

[0025] In another embodiment provided by this utility model, such as Figure 5 As shown, the cross-section of the fixed end 8 is square. When the fixed end 8 is a square column, the channel 17 is also square. The bottom inner wall of the channel 17 has a gap with the bottom outer wall of the fixed end 8, and the bottom outer wall of the cover plate 5 also has a gap with the top outer wall of the fixed end 8. This allows the fixed end 8 to rotate slightly inside the channel 17 with the limiting post 15 as the hinge point, thereby making the connection between structure 1 and structure 2 more flexible.

[0026] Working principle: When in use, place the fixed end 8 inside the channel 17 of the first slot box 3, and insert the movable end 10 into the channel 18 of the second slot box 4. Then, place the mating block 14 inside the mating groove 13, and make the limiting post 15 engage with the limiting groove 16 of the fixed end 8. Then, install the cover plate 5 on the first slot box 3 and the second slot box 4 respectively.

[0027] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
