Description

Technical Field

[0001] This utility model belongs to the technical field of components for rapid assembly and reinforcement of mortise and tenon structures, specifically relating to a component for rapid assembly and reinforcement of mortise and tenon structures. Background Technology

[0002] Mortise and tenon joints are a traditional woodworking connection method. They achieve a tight connection between components by interlocking the protruding tenon and the recessed mortise. For reinforcement, traditional methods usually use iron sheets, nails or tinplate to enhance the stability of the mortise and tenon joints.

[0003] The connection method of beams and columns in ancient wooden structures is mostly mortise and tenon joints. For ease of installation, the size of the mortise is often slightly larger than that of the tenon. There is an initial gap between the tenon and the mortise. Over time, the shrinkage of the wood itself and the influence of the natural environment cause the gap to widen, resulting in loosening of the joint. Especially under the action of earthquake, the joint can no longer meet the seismic requirements, causing serious damage such as tenon pull-out and tenon breakage. Therefore, it is of great significance to reinforce the mortise and tenon joints of ancient wooden structures.

[0004] Currently, mortise and tenon joints are commonly used to fix wooden bench frames. For ease of installation, the mortise is often slightly larger than the tenon, resulting in an initial gap between the tenon and the mortise. However, with prolonged use, the gap gradually widens due to changes in the wood itself and external influences, causing the bench to loosen. This is especially problematic when the user shakes the bench, which can easily lead to its collapse, resulting in low safety and significant damage.

[0005] Therefore, in view of the above-mentioned technical problems, it is necessary to provide a component for rapid assembly and reinforcement of mortise and tenon structures.

[0006] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

Detailed Implementation

[0027] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0028] like Figures 1 to 5 As shown, an embodiment of this utility model provides a component for rapid assembly and reinforcement of mortise and tenon structures, comprising: a support crossbar 1, a pair of support struts 2, a pair of pull ropes 3, and a pair of tightening and positioning mechanisms 4. The support crossbar 1 supports the bench surface. The pair of support struts 2 are respectively located on both sides of the support crossbar 1 and connected to it via a mortise and tenon structure. The pair of pull ropes 3 are sleeved on the outside of the pair of support struts 2 and positioned on the upper and lower sides of the support crossbar 1. The tightening and positioning mechanism 4 includes a tightening component 41 and a positioning component 42 mounted on the support crossbar 1. The tightening component 41 and the positioning component 42 cooperate to tighten the pair of support struts 2 via the pull ropes 3. The pull ropes 3 can pull the pair of support struts 2, bringing them closer together and improving their stability.

[0029] The method of using the component for quick splicing and reinforcement of mortise and tenon structures is as follows: Install a pair of support rods 2 to the support crossbar 1 through the mortise and tenon structure. By rotating the tightening component 41, the pull rope 3 is pulled closer together through the twisting of the pull rope 3, making the fixing effect of the pair of support rods 2 more ideal. The tightening component 41 is locked in place by the positioning component 42, so that the positioning component 42 stops rotating and the twisting of the pull rope 3 is fixed. Even if it loosens later, the distance between the pair of support rods 2 can be continuously pulled closer by rotating the tightening component 41.

[0030] like Figures 1 to 3 As shown, the tightening assembly 41 includes a tightening mounting bracket 411 and a tightening mounting shaft 412. The tightening mounting bracket 411 is fixedly mounted on the support crossbar 1. The tightening mounting shaft 412 is rotatably mounted within the tightening mounting bracket 411 and slidably mounted with the pull rope 3. The tightening mounting bracket 411 can fix the position of the tightening mounting shaft 412, reducing the probability of the tightening mounting shaft 412 disengaging, improving the stability of the tightening mounting shaft 412, reducing the probability of the tightening mounting shaft 412 tilting, and improving the balance of the tightening mounting shaft 412. The tightening mounting shaft 412 facilitates the installation of the pull rope 3. By rotating the tightening mounting shaft 412, the pull rope 3 can be twisted, allowing the pull rope 3 to pull a pair of support struts 2 closer together.

[0031] The pull rope 3 passes through the tightening mounting shaft 412, which facilitates the installation of the pull rope 3 and allows the rotation of the tightening mounting shaft 412 to twist the pull rope 3. A tightening bearing 413 is installed between the tightening mounting shaft 412 and the tightening mounting frame 411. When the tightening mounting shaft 412 rotates, the friction between the tightening mounting shaft 412 and the tightening mounting frame 411 is reduced, making the rotation of the tightening mounting shaft 412 smoother and more stable.

[0032] In addition, a tightening turntable 414 is fixedly installed on the tightening mounting shaft 412, which facilitates the user's control of the tightening mounting shaft 412 and enables the tightening mounting shaft 412 to rotate.

[0033] like Figures 1 to 5 As shown, the positioning component 42 includes: a positioning mounting chamber 421, a positioning sliding plate 422, and a positioning locking disc 423. The positioning mounting chamber 421 is fixedly mounted on the support crossbar 1. The positioning sliding plate 422 is slidably mounted within the positioning mounting chamber 421. The positioning locking disc 423 is fixedly mounted on the side of the tightening mounting shaft 412 away from the tightening turntable 414. The positioning mounting chamber 421 facilitates the sliding of the positioning sliding plate 422, improves the stability of the positioning sliding plate 422, and provides guidance for the positioning sliding plate 422 from the positioning mounting chamber 421.

[0034] In addition, the positioning sliding plate 422 can engage the positioning locking disc 423, reducing the chance of the tightening mounting shaft 412 rotating.

[0035] The positioning card plate 423 can be fixed by the positioning sliding plate 422, which reduces the probability of the tightening mounting shaft 412 rotating and allows the rotation of the tightening mounting shaft 412 to be positioned.

[0036] like Figures 1 to 3 As shown, the positioning installation chamber 421 is provided with a plurality of positioning springs 424. The positioning springs 424 are located between the positioning sliding plate 422 and the positioning installation chamber 421. The positioning springs 424 can compress the positioning sliding plate 422, so that the sliding of the positioning sliding plate 422 is supported, and the positioning sliding plate 422 can better engage with the positioning locking disc 423.

[0037] like Figures 1 to 3 As shown, the positioning locking disc 423 has several evenly distributed limiting grooves. The limiting grooves match the positioning sliding plate 422. The limiting grooves allow the positioning locking disc 423 to be engaged by the positioning sliding plate 422, so that the positioning locking disc 423 is positioned by the positioning sliding plate 422.

[0038] The positioning sliding plate 422 is installed through the positioning installation compartment 421, which facilitates the sliding of the positioning sliding plate 422 and improves the guiding effect of the positioning sliding plate 422.

[0039] In addition, a positioning pull ring 425 is fixedly installed on the positioning sliding plate 422, which can be easily pulled by the user and provides corresponding convenience for the compression of the positioning spring 424.

[0040] In addition, the positioning installation chamber 421 is provided with a positioning groove that matches the positioning pull ring 425, which facilitates the sliding of the positioning pull ring 425 and provides corresponding space for the sliding of the positioning pull ring 425.

[0041] In practical use, the user attaches the pull rope 3 to a pair of support rods 2. By rotating the tightening turntable 414, the mounting shaft 412 with the positioning locking disc 423 can be tightened and rotated. At the same time, the pull rope 3 is twisted, causing the pull rope 3 to pull the pair of support rods 2, bringing the pair of support rods 2 closer to each other, thereby improving the stability of the mortise and tenon structure. Meanwhile, the positioning sliding plate 422 is squeezed by the positioning spring 424, causing the positioning sliding plate 422 to lock onto the positioning locking disc 423, thus fixing the twist of the pull rope 3.

[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
