Description

Technical Field

[0001] This utility model relates to the field of prefabrication technology, and in particular to a prefabricated connector for assembled buildings. Background Technology

[0002] Prefabricated buildings are typically assembled on-site using precast panels. The connection structure between the precast panels is made using bolts and nuts, which is complex and makes on-site construction very troublesome, resulting in a complicated and inefficient assembly process for the precast panels.

[0003] Currently, the traditional method for connecting prefabricated components in prefabricated buildings is to use bolts. This requires two people to work together to tighten the bolts, which is inefficient, especially when working at heights, and carries the risk of loosening. Summary of the Invention

[0004] To overcome the technical defects of the existing technology, this utility model provides a prefabricated connector for prefabricated buildings, which achieves locking upon insertion through inclined plane guidance and elastic self-locking, resulting in high docking efficiency.

[0005] The technical solution adopted by this utility model is: a prefabricated connector for prefabricated buildings, including a first prefabricated component and a second prefabricated component, the opposite ends of the first prefabricated component and the second prefabricated component are connected by a quick-release locking mechanism; the quick-release locking mechanism includes a positioning block provided on one side of the first prefabricated component, the top of the positioning block is provided with a vertically sliding connecting latch and an elastic element for driving the connecting latch to reset, one side of the second prefabricated component is provided with a positioning slot that cooperates with the positioning block, the inner wall of the positioning slot is provided with a connecting lock hole that cooperates with the latch, the opening of the connecting lock hole is provided with a beveled guide, and the outer end of the connecting latch is provided with an inclined surface that cooperates with the beveled guide.

[0006] Preferably, the tilt angle of the inclined face at the end of the connecting latch is set to 15°-30°.

[0007] Preferably, the elastic element is a pre-compressed disc spring assembly.

[0008] Preferably, the top ends of the first preform and the second preform are provided with protective cover plates covering the top ends of the first preform and the second preform.

[0009] Preferably, both the top sides of the first preform and the second preform are provided with L-shaped disassembly guide slides, and both the bottom sides of the protective cover are provided with disassembly guide slides that cooperate with the disassembly guide slides.

[0010] Preferably, the top of the second preform has a pressing hole concentric with the connecting lock hole, the inside of the pressing hole has a T-shaped pressing rod, and the top of the pressing rod has a pressing button.

[0011] Preferably, a protective groove is provided on the side of the protective cover plate near the first preform and the second preform, and a strip plate that cooperates with the protective groove is provided at the top of both the first preform and the second preform.

[0012] A spring pin is embedded on one side of the end of the disassembly guide slide, and a limiting hole matching the pin of the spring pin is opened on one side of the disassembly guide slide.

[0013] The beneficial effects of this utility model are as follows: When the first prefabricated part and the second prefabricated part are connected, the inclined surface of the end of the connecting tongue abuts against the inclined guide part of the inner wall of the positioning slot to generate a radial component force. The inclined guide part squeezes the connecting tongue to retract into the positioning block until the connecting tongue is radially ejected into the connecting lock hole under the action of the elastic element, forming a self-locking state without external force intervention. The inclined guide and elastic self-locking realize the locking upon pushing in. Only one person is needed to complete the connection of the first prefabricated part and the second prefabricated part, avoiding the situation where two people are needed to complete the connection in the traditional bolt connection. This improves the efficiency of the connection of the first prefabricated part and the second prefabricated part, and there is no risk of loosening, so the safety is high.

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been provided in the various embodiments of this utility model to facilitate a better understanding of this application. However, the technical solutions claimed in the claims of this application can be implemented even without these technical details and with various variations and modifications based on the following embodiments.

[0018] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment provides a prefabricated connector for prefabricated buildings, including a first prefabricated component 1 and a second prefabricated component 2. The opposite ends of the first prefabricated component 1 and the second prefabricated component 2 are connected by a quick-release locking mechanism 3. The quick-release locking mechanism 3 includes a positioning block 301 on one side of the first prefabricated component 1. The top of the positioning block 301 is provided with a vertically sliding connecting latch 302 and an elastic element 303 for driving the connecting latch 302 to reset. The elastic element 303 is a pre-compressed disc spring assembly. One side of the second prefabricated component 2 is provided with a positioning slot 304 that cooperates with the positioning block 301. The inner wall of the positioning slot 304 is provided with a connecting lock hole 305 that cooperates with the connecting latch 302. The opening of the connecting lock hole 305 is provided with a beveled guide portion 306, and the outer end of the connecting latch 302 is provided with a beveled guide portion. When the inclined surface 307 of the connecting tongue 302 is used to mate with the first precast part 1 and the second precast part 2, the inclined surface 307 of the connecting tongue 302 abuts against the inclined guide part 306 of the inner wall of the positioning slot 304 to generate a radial force. The inclined guide part 306 squeezes the connecting tongue 302 to retract into the positioning block 301 until the connecting tongue 302 is radially ejected into the connecting lock hole 305 under the action of the elastic element 303, forming a self-locking state without external force intervention. The inclined guide and elastic self-locking achieve push-in locking. Only one person is needed to complete the docking of the first precast part 1 and the second precast part 2, avoiding the situation where the traditional bolt connection requires two people to complete the docking. This improves the efficiency of docking the first precast part 1 and the second precast part 2, and there is no risk of loosening, so the safety is high.

[0019] The tilt angle of the inclined surface 307 at the end of the connecting latch 302 is set to 15°-30°.

[0020] The top ends of the first preform 1 and the second preform 2 are provided with protective cover plates 4 covering the top ends of the first preform 1 and the second preform 2. The protective cover plates 4 can cover the top ends of the first preform 1 and the second preform 2, making the connection stability of the first preform 1 and the second preform 2 higher, and also providing good protection for the push button 11.

[0021] Both the top sides of the first preform 1 and the second preform 2 are provided with L-shaped disassembly guide slide rails 5, and both sides of the bottom of the protective cover plate 4 are provided with disassembly guide slide strips 6 that cooperate with the disassembly guide slide rails 5. When assembling the protective cover plate 4, the disassembly guide slide strips 6 on the protective cover plate 4 move along the disassembly guide slide rails 5.

[0022] The second prefabricated component 2 has a pressing hole 7 at its top, which is concentric with the connecting lock hole 305. Inside the pressing hole 7 is a T-shaped pressing rod 8. The top of the pressing rod 8 is a pressing button 11. When disassembling, simply push the pressing button 11 downwards. The pressing button 11 pushes the pressing rod 8 to move along the pressing hole 7 and acts on the connecting lock tongue 302. This overcomes the elastic force of the elastic element 303 and causes the connecting lock tongue 302 to exit the connecting lock hole 305, achieving quick and non-destructive disassembly. This is especially suitable for maintenance during high-altitude operations.

[0023] The protective cover plate 4 has a protective groove 9 on the side near the first preform 1 and the second preform 2. The top of the first preform 1 and the second preform 2 are provided with strip plates 10 that cooperate with the protective groove 9. The protective groove 9 and the strip plates 10 cooperate to prevent external corrosive substances from entering.

[0024] A spring pin 12 is embedded on one side of the end of the disassembly guide slide 6, and a limiting hole 13 matching the pin of the spring pin 12 is opened on one side of the disassembly guide slide 5. When the protective cover 4 is placed on the top of the first precast part 1 and the second precast part 2, the spring pin 12 matches the limiting hole 13 under the elastic force of the spring pin 12, thus locking the protective cover 4.

[0025] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0026] During operation, when the first precast component 1 and the second precast component 2 are connected, the inclined surface 307 at the end of the connecting latch 302 abuts against the inclined guide portion 306 on the inner wall of the positioning slot 304, generating a radial force. The inclined guide portion 306 compresses the connecting latch 302 and retracts it into the positioning block 301 until the connecting latch 302 is radially ejected into the connecting lock hole 305 under the action of the elastic element 303, forming a self-locking state without external force intervention. Through the inclined guide and elastic self-locking, the first precast component 1 and the second precast component 2 can be connected by a single person, avoiding the situation where traditional bolt connections require two people to cooperate to complete the connection. This improves the efficiency of connecting the first precast component 1 and the second precast component 2, and there is no risk of loosening, resulting in high safety.

[0027] Those skilled in the art will understand that the above embodiments are specific examples of implementing the present invention, and in practical applications, various changes can be made to them in form and detail without departing from the spirit and scope of the present invention.
