Technical Field

[0001] This utility model belongs to the technical field of rafter connectors, specifically relating to a rafter connector. Background Technology

[0002] Rafter connectors are devices used to fix or connect rafters to structural components such as ridges, walls, or roof beams in a roof structure. Their function is to enhance structural stability, transfer loads, and ensure the overall safety of the roof system.

[0003] Existing rafter connectors are generally connected to the rafters by drilling holes. This method requires precise drilling, alignment, and the use of specialized tools (such as impact wrenches), resulting in low construction efficiency, high skill requirements for workers, and a high risk of bolt hole misalignment, leading to uneven stress on the connector after installation. Therefore, we propose a new rafter connector. Summary of the Invention

[0008] Preferably, a limiting groove is formed on one side of the guide block, and an internal groove is formed through one side of the inner wall of the guide groove. A limiting buckle is symmetrically arranged inside the internal groove. The limiting buckle is engaged with the limiting groove. A through hole is formed through the end of the limiting buckle. A connecting rod with both ends passing through the through hole is arranged inside the internal groove. A telescopic spring is sleeved on the surface of the connecting rod.

[0009] Preferably, the inner wall of the built-in groove is symmetrically provided with sliding grooves, and the two sides of the limiting buckle are symmetrically fixed with sliders, and the sliders are slidably connected to the sliding grooves.

[0010] Preferably, the connecting locking assembly includes locking holes symmetrically opened on both sides of the locking block and screw holes symmetrically opened through both sides of the inner wall of the slot. The rafters are symmetrically provided with locking rods that pass through the screw holes and connect to the locking holes. The locking rods are screwed and fixedly connected to the locking holes.

[0011] Preferably, the assembly docking mechanism includes docking grooves symmetrically opened at the other end of the connector and docking blocks fixed inside the docking grooves.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

Detailed Implementation

[0019] 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.

[0020] Please see Figures 1 to 4This utility model provides a technical solution: a rafter connector, including a rafter 1, a connector 2 is provided at the end of the rafter 1, a guide connection mechanism is provided between the connector 2 and the rafter 1, and an assembly docking mechanism is provided at the end of the connector 2. The guide connection mechanism includes: a snap-fit ​​limiting component and a connection locking component.

[0021] In this embodiment, preferably, the snap-fit ​​limiting component includes a slot 100 formed at the end of the rafter 1 and a snap block 101 fixed at one end of the connector 2. The snap block 101 engages with the slot 100 to facilitate the connection between the connector 2 and the rafter 1.

[0022] In this embodiment, preferably, guide grooves 200 are symmetrically provided at the ends of the card block 101, and guide blocks 201 are symmetrically fixed inside the card groove 100. By engaging and connecting the guide blocks 201 with the guide grooves 200, the card block 101 can play a connecting and guiding role when it is embedded inside the card groove 100.

[0023] In this embodiment, preferably, a limiting groove 300 is formed on one side of the guide block 201, and an internal groove 301 is formed through one side of the inner wall of the guide groove 200. A limiting buckle 302 is symmetrically arranged inside the internal groove 301. By engaging the limiting buckle 302 with the limiting groove 300, the guide block 201 can be temporarily limited inside the guide groove 200. A through hole 303 is formed through the end of the limiting buckle 302. A connecting rod 304 is provided inside the internal groove 301, with both ends passing through the through hole 303. A telescopic spring 305 is sleeved on the surface of the connecting rod 304, which can drive the limiting buckle 302 to reset when it is squeezed by external force.

[0024] In this embodiment, preferably, the inner wall of the built-in groove 301 is symmetrically provided with sliding grooves 400, and the two sides of the limiting buckle 302 are symmetrically fixed with sliders 401. The sliders 401 are slidably connected with the sliding grooves 400, which can play a guiding and limiting role when the limiting buckle 302 moves.

[0025] In this embodiment, preferably, the connecting locking assembly includes locking holes 500 symmetrically opened on both sides of the locking block 101 and screw holes 501 symmetrically opened through both sides of the inner wall of the slot 100. The rafter 1 is symmetrically provided with locking rods 502 that pass through the inside of the screw holes 501 and connect to the locking holes 500. The locking rods 502 are screwed and fixedly connected to the locking holes 500, so that the locking block 101 can be firmly fixed inside the slot 100, so that the connector 2 can be connected to the rafter 1.

[0026] In this embodiment, preferably, the assembly docking mechanism includes docking grooves 600 symmetrically opened at the other end of the connector 2 and docking blocks 601 fixed inside the docking grooves 600, which can play an assembly docking role when the connector 2 is connected to docking parts of other components.

[0027] The working principle and usage process of this utility model are as follows: When it is necessary to fix the connector 2 to the rafter 1, first connect one end of the connector 2 to the end of the rafter 1, so that the locking block 101 is embedded in the inside of the locking groove 100, and drives the guide groove 200 to engage with the guide block 201. When the guide block 201 is embedded in the inside of the guide groove 200, it will squeeze the limiting buckle 302. The limiting buckle 302 is squeezed into the inside of the built-in groove 301 by external force, and drives the through hole 303 to slide on the surface of the connecting rod 304, squeezing the telescopic spring 305 to deform. At the same time, it drives the slider 401 to slide inside the sliding groove 400 to play a moving guiding role, so that the guide block 201 can be completely locked. The guide groove 200 serves as a guide. At this time, the limit buckle 302 is reset and popped out from the inside of the built-in groove 301 under the action of the telescopic spring 305 and is inserted into the inside of the limit groove 300. This temporarily limits the locking block 101 and ensures that the locking hole 500 and the screw hole 501 are accurately aligned. Then, the locking rod 502 passes through the screw hole 501 from both ends of the rafter 1 and is screwed into the locking hole 500 to fix it. This fixes the connector 2 and the rafter 1 together, so that the rafter 1 can be connected to other metal or wooden components through the connector 2. The connector 2 can also be assembled and connected to the docking block 601 through the docking groove 600 at the other end.

[0028] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
