Description

Technical Field

[0001] This utility model relates to the field of drilling device technology, specifically a drilling device for wooden components. Background Technology

[0002] In the restoration of ancient buildings, the reinforcement and maintenance of wooden components such as ancient wooden pillars and roof trusses are the core links. In order to enhance the structural stability of the components, it is necessary to drill holes in specific locations and insert reinforcement parts. In this type of operation, manual woodworking chisels have become one of the mainstream tools for drilling holes in ancient wooden components due to their advantages such as high precision of operation, no risk of damage from the recoil force of electric tools, and no need to rely on power.

[0003] In existing technologies, manual woodworking chisels used for ancient wood restoration generally adopt an integrated structure, with the core consisting of a chisel head and a chisel body fixedly connected. This type of integrated chisel can meet the basic requirements in conventional scenarios of ancient wood restoration (such as the outer side of ancient wooden pillars and the outer plane of wooden roof trusses). However, the restoration of ancient wooden components often involves narrow spaces. The chisel body of existing manual chisels has a fixed length. In narrow spaces, after the chisel body is inserted, the chisel tail may not protrude sufficiently, making it difficult for the hammer to effectively strike the chisel tail and causing inconvenience for workers. Therefore, a wood component drilling device is proposed to address the above situation. Summary of the Invention

[0004] The purpose of this utility model is to provide a wood component chiseling device. Through the structural design of a first connecting rod, a threaded rod, a threaded ring, a positioning rod, a second connecting rod, and a third connecting rod, the length of the connecting part can be adjusted by folding the connecting part. After folding, the overall length can be shortened, which is suitable for the typical narrow space conditions in ancient wood restoration. This improves the comfort and ease of operation for workers in actual work. It solves the problem that the chisel body length of existing manual chisels is fixed, and in narrow spaces, the chisel tail is often not long enough after the chisel body is inserted, which makes it difficult for the hammer to effectively strike the chisel tail.

[0005] This utility model is achieved through the following technical solution: This utility model is a device for drilling holes in wooden components, including a chisel body for drilling holes in wooden components. A connecting part is fixed to the top of the chisel body. The connecting part includes a first connecting rod, a second connecting rod and a third connecting rod. A threaded rod is fixed to the top of the first connecting rod. A threaded ring is threaded onto the threaded rod, and a positioning rod is fitted onto the threaded ring.

[0006] The bottom of the second connecting rod is fixed to the top of the threaded rod. Grooves are provided on both sides of the second connecting rod, and through holes are provided on the bottom surface of the grooves. The through holes are fitted with the positioning rod with clearance.

[0007] The third connecting rod rotates on the second connecting rod. Positioning holes are provided at both ends of the bottom of the third connecting rod. When the third connecting rod rotates to be on the same central axis as the second connecting rod, the positioning rod passes through the through hole and extends into the positioning hole.

[0008] Furthermore, a rotating hole is provided through the side wall of the groove, and a rectangular groove is provided at the bottom of the third connecting rod. A rotating shaft is rotatably mounted on the inner wall of the rectangular groove, and the rotating shaft is interference-fitted with the rotating hole.

[0009] Furthermore, an annular plate is rotatably mounted on the top of the threaded ring, and positioning rods are fixed on the annular plate. There are four positioning rods, which are distributed in a rectangular pattern on the annular plate.

[0010] Furthermore, the inner wall of the threaded ring is provided with an internal thread adapted to the threaded rod, and the outer wall of the threaded ring is provided with a rubber sleeve with anti-slip texture.

[0011] Furthermore, when the third connecting rod rotates to be on the same central axis as the second connecting rod, the center of the positioning hole and the center of the through hole coincide.

[0012] This utility model has the following beneficial effects: This utility model, through its structural design of a first connecting rod, a threaded rod, a threaded ring, a positioning rod, a second connecting rod, and a third connecting rod, allows for length adjustment of the connecting part by folding it during use. The overall length can be shortened after folding, making it suitable for the typical narrow space conditions in ancient wood restoration and improving the comfort and ease of operation for workers.

[0013] This utility model, through the structural design of threaded rod, threaded ring, positioning rod and positioning hole, can position the third connecting rod during normal use, avoid problems such as rotation of the third connecting rod during use, ensure the stability of the connection part in working state, and at the same time improve the impact strength of the third connecting rod and extend the service life of the rotating shaft.

[0021] 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.

[0022] Please see Figure 1-5 This utility model provides a technical solution: a wooden component drilling device, including a chisel body 1 for drilling holes in wooden components, such as... Figure 1 As shown, holes are drilled in ancient wooden pillars or wooden houses. A connecting part 2 is fixed to the top of the chisel body 1. The connecting part 2 includes a first connecting rod 20, a second connecting rod 24 and a third connecting rod 25. A threaded rod 21 is fixed to the top of the first connecting rod 20. A threaded ring 22 is threaded onto the threaded rod 21. A positioning rod 23 is fitted onto the threaded ring 22.

[0023] The chisel body 1 is made of high carbon steel. Its top and the bottom of the first connecting rod 20 adopt a composite fixing structure of "welding + tenon". The top of the chisel body 1 is integrally formed with a rectangular tenon. The bottom of the first connecting rod 20 is provided with a matching rectangular mortise. After the tenon is joined, it is reinforced by high frequency welding to prevent relative rotation between the chisel body 1 and the connecting part 2 during chiseling. The first connecting rod 20 is a solid alloy rod made of 304 stainless steel.

[0024] The bottom of the second connecting rod 24 is fixed to the top of the threaded rod 21. Grooves 240 are respectively opened on both sides of the second connecting rod 24. A through hole 242 is opened through the bottom surface of the groove 240. The through hole 242 is clearance-fitted with the positioning rod 23.

[0025] The third connecting rod 25 rotates on the second connecting rod 24. Positioning holes 252 are provided at both ends of the bottom of the third connecting rod 25. When the third connecting rod 25 rotates to be on the same central axis as the second connecting rod 24, the positioning rod 23 passes through the through hole 242 and extends into the positioning hole 252.

[0026] In this embodiment, a rotating hole 241 is provided through the side wall of the groove 240, and a rectangular groove 250 is provided at the bottom of the third connecting rod 25. A rotating shaft 251 is rotatably mounted on the inner wall of the rectangular groove 250. The rotating shaft 251 is interference-fitted with the rotating hole 241. The rotating shaft 251 is a damping rotating shaft.

[0027] In this embodiment, an annular plate is rotatably mounted on the top of the threaded ring 22, and positioning rods 23 are fixed on the annular plate. There are four positioning rods 23, which are distributed in a rectangular shape on the annular plate.

[0028] The annular plate at the top of the threaded ring 22 is rotatably connected to the threaded ring 22 via a bearing, ensuring that when the threaded ring 22 is rotated for adjustment, the annular plate and the positioning rod 23 move only axially.

[0029] In this embodiment, the inner wall of the threaded ring 22 is provided with an internal thread adapted to the threaded rod 21, and the outer wall of the threaded ring 22 is provided with a rubber sleeve with anti-slip texture to prevent slippage due to sweaty hands.

[0030] In this embodiment, when the third connecting rod 25 rotates to be on the same central axis as the second connecting rod 24, the center of the positioning hole 252 and the center of the through hole 242 coincide with each other. When the third connecting rod 25 rotates, the rectangular groove 250 can completely accommodate the top of the second connecting rod 24, thus avoiding structural interference.

[0031] The top of the third connecting rod 25 and the second connecting rod 24 are integrally formed with a chisel tail, and the surface of the chisel tail is chrome-plated to improve wear resistance.

[0032] When using the above device: When it is necessary to rotate the third connecting rod 25 to meet the needs of narrow working conditions: rotate the threaded ring 22 counterclockwise, and the threaded ring 22 moves downward along the threaded rod 21, driving the positioning rod 23 to be pulled out from the positioning hole 252 and the through hole 242 until the positioning rod 23 is completely separated from the third connecting rod 25 and flush with the bottom surface of the groove 240. Hold the chisel tail at the top of the third connecting rod 25 and rotate it around the pivot 251 toward the groove 240 of the second connecting rod 24. Temporarily fix the angle by the friction of the damping pivot. Align the chisel head of the chisel body 1 with the target chisel hole position of the ancient wood component. Adjust the hand grip according to the space size to ensure that the chisel head is at a preset angle to the surface of the ancient wood. Strike the top of the second connecting rod 24 with a wooden hammer or claw hammer. The force is transmitted to the chisel body 1 through the rigidity of the connecting part 2, so that the chisel head chisels the ancient wood.
