Description

Technical Field

[0001] This utility model relates to the field of metal saw blade anti-breakage technology, specifically a metal saw blade anti-breakage reinforcement structure. Background Technology

[0002] Metal saw blades are mainly used for cutting metal and non-metal materials. The saw blade is composed of a saw blade and saw teeth. In order to prevent the metal saw blade from breaking during the cutting process, a metal saw blade anti-breakage reinforcement structure is needed.

[0003] In existing technologies, the saw blade is installed by fixing both ends with a handgrip, making it easy to cut both metal and non-metal materials. However, in actual use, cutting materials of different volumes requires saw blades of different lengths. Existing handgrips can only fix a single length of saw blade, which is limiting and increases costs. Furthermore, since the handgrip only fixes both ends of the saw blade, the rest of the blade is suspended, causing it to wobble significantly during cutting, which can easily lead to deformation or even breakage, and may also injure operators. Therefore, it is necessary to develop a reinforced structure to prevent breakage of metal saw blades to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide a reinforced structure for preventing breakage of metal saw blades, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a metal saw blade anti-breakage reinforcement structure, including a handle and a saw blade, with mounting blocks fixedly installed on both the left and right sides of the saw blade, and reinforcing saw teeth fixedly installed on the bottom of the saw blade, with an installation mechanism inside the handle, and a reinforcement mechanism inside the installation mechanism.

[0006] Preferably, the mounting mechanism includes a handle, which is rotatably mounted inside the handle. A bevel gear one is fixedly mounted on the back of the handle, and two bevel gears two mesh with the outer sides of the bevel gear one. Threaded rods are fixedly mounted on the outer sides of the two bevel gears two. A mounting bracket is mounted on the outer threads of the threaded rods, and a bolt is mounted on the inner threads of the mounting brackets, thus completing the installation of the saw blade.

[0007] Preferably, the mounting block is disposed inside the mounting bracket, and the bolt is threaded inside the mounting block, thereby completing the installation of the two mounting blocks and the two mounting brackets.

[0008] Preferably, the mounting bracket is slidably mounted inside the handle, and the threaded rod is rotatably mounted inside the handle, thereby moving the mounting bracket.

[0009] Preferably, the reinforcing mechanism includes a positioning frame, which is fixedly installed inside the mounting frame. A reinforcing frame is rotatably installed on the outside of the positioning frame. A limit groove is formed inside the reinforcing frame. A rectangular block is fixedly installed on the side of the reinforcing frame away from the hand grip. A spring is fixedly installed inside the positioning frame. A movable plate is fixedly installed on the end of the spring away from the positioning frame. A positioning column is fixedly installed on the side of the movable plate away from the spring to fix the position of the reinforcing frame.

[0010] Preferably, the positioning post is slidably installed inside the positioning frame, and the reinforcing frame has two positioning holes at corresponding positions of the positioning post, with the positioning post inserted into the positioning holes. The movable plate is slidably installed inside the positioning frame, driving the positioning post to move.

[0011] Preferably, the reinforcing frame is movably installed inside the mounting frame, and the saw blade is engaged inside the limiting groove, so that the reinforcing frame strengthens and fixes the saw blade.

[0012] Compared with the prior art, this utility model provides a metal saw blade anti-breakage reinforcement structure, which has the following beneficial effects:

[0013] 1. The metal saw blade features a fracture-resistant reinforced structure. Through the cooperation of a rotating handle, bevel gear one, two bevel gears two, and two threaded rods, two mounting brackets can be moved. After adjustment, the mounting brackets and mounting blocks are installed using bolts, thus completing the installation of the saw blade. The position of the two mounting brackets can be adjusted according to the length of the saw blade, making it more flexible to use.

[0014] 2. Based on this, the present invention allows the positioning post to disengage from the positioning hole of the reinforcing frame by pulling the movable plate, rotating the reinforcing frame to a vertical position, and then releasing the movable plate. At this time, the spring rebounds and drives the movable plate to reset, so that the positioning post is inserted into another positioning hole of the reinforcing frame, and the saw blade is locked in the limiting groove, thereby completing the reinforcement and fixation of the saw blade and avoiding the problem of the saw blade easily breaking due to large shaking amplitude during use.

[0015] 3. Based on this, the number of reinforcing frames in this utility model can be selectively used according to the length of the saw blade, so as to strengthen and fix the saw blade without affecting the use of the middle area of ​​the saw blade. Attached Figure Description

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.

[0024] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0025] Example 1:

[0026] Please see Figure 1-3 This utility model provides a technical solution: a metal saw blade anti-breakage reinforcement structure, including a handle 1 and a saw blade 2, with mounting blocks 3 fixedly installed on both the left and right sides of the saw blade 2, and reinforcing saw teeth 4 fixedly installed on the bottom of the saw blade 2. An installation mechanism 5 is provided inside the handle 1, and a reinforcement mechanism 6 is provided inside the installation mechanism 5.

[0027] Furthermore, the mounting mechanism 5 includes a handle 51, which is rotatably mounted inside the handle 1. A bevel gear 52 is fixedly mounted on the back of the handle 51. Two bevel gears 53 mesh externally with the bevel gear 52. Threaded rods 54 are fixedly mounted on the outer sides of both bevel gears 53. A mounting bracket 55 is mounted on the external threads of the threaded rod 54. Bolts 56 are mounted on the internal threads of the mounting bracket 55, thus completing the installation of the saw blade 2.

[0028] Furthermore, the mounting block 3 is placed inside the mounting bracket 55, and the bolt 56 is threaded inside the mounting block 3, thus completing the installation of the two mounting blocks 3 with the two mounting brackets 55.

[0029] Furthermore, the mounting bracket 55 is slidably mounted inside the handle 1, and the threaded rod 54 is rotatably mounted inside the handle 1, driving the mounting bracket 55 to move.

[0030] Example 2:

[0031] Please see Figure 4-5 Furthermore, in conjunction with Embodiment 1, the reinforcing mechanism 6 includes a positioning frame 61, which is fixedly installed inside the mounting frame 55. A reinforcing frame 62 is rotatably installed on the outside of the positioning frame 61. A limiting groove 63 is formed inside the reinforcing frame 62. A rectangular block 64 is fixedly installed on the side of the reinforcing frame 62 away from the hand grip 1. A spring 65 is fixedly installed inside the positioning frame 61. A movable plate 66 is fixedly installed on the end of the spring 65 away from the positioning frame 61. A positioning post 67 is fixedly installed on the side of the movable plate 66 away from the spring 65 to fix the position of the reinforcing frame 62.

[0032] Furthermore, the positioning post 67 is slidably installed inside the positioning frame 61, and the reinforcing frame 62 has two positioning holes at the corresponding positions of the positioning post 67, with the positioning post 67 inserted into the positioning holes. The moving plate 66 is slidably installed inside the positioning frame 61, driving the positioning post 67 to move.

[0033] Furthermore, the reinforcing frame 62 is movably installed inside the mounting frame 55, and the saw blade 2 is engaged inside the limiting groove 63, so that the reinforcing frame 62 strengthens and fixes the saw blade 2.

[0034] In actual operation, when this device is used, rotating the handle 51 causes the first bevel gear 52 to rotate and mesh with the two second bevel gears 53. The two threaded rods 54 rotate inside the handle 1, and the two mounting brackets 55 are threaded onto the outside of the two threaded rods 54, so that the threaded hole at the end of the mounting bracket 55 away from the handle 51 corresponds to the position of the mounting block 3. Then, the two mounting blocks 3 and the two mounting brackets 55 are installed using two bolts 56, thus completing the installation of the saw blade 2. The position of the two mounting brackets 55 can be adjusted according to the length of the saw blade 2, making it more flexible to use. Strengthening the saw teeth 4 extends the service life of the saw blade 2. After the saw blade 2 is installed, pulling the moving plate 66 causes the positioning post 67 to disengage from the reinforcing frame 62, compressing the spring 65. The spring 65 is initially in a stretched state, and the positioning post 67 disengages from the reinforcing frame 62. Inside the positioning hole of the reinforcing frame 62, the reinforcing frame 62 rotates around the positioning frame 61 under the action of gravity until the reinforcing frame 62 is in a vertical state. When the reinforcing frame 62 is blocked inside the mounting frame 55 and cannot rotate, the rectangular block 64 can be moved to rotate the reinforcing frame 62 to a vertical state. When the reinforcing frame 62 is in a vertical state, the saw blade 2 is set inside the limiting groove 63. Then the moving plate 66 is released. At this time, the spring 65 rebounds and drives the moving plate 66 to reset, so that the positioning post 67 is inserted into another positioning hole of the reinforcing frame 62, so that the reinforcing frame 62 is always in a vertical state to limit the saw blade 2 and strengthen and fix the saw blade 2, avoiding the problem that the saw blade 2 is prone to breakage due to large shaking amplitude during use. The number of reinforcing frames 62 can be selectively used according to the length of the saw blade 2, so as to strengthen and fix the saw blade 2 without affecting the use of the middle area of ​​the saw blade 2.

[0035] It should be added that the contact surface between the handle 51 and the grip bar 1 is also equipped with a damping pad, which requires a little force when rotating (this does not affect the use of adults), and at the same time, it can maintain its stability when stationary with the help of damping friction.

[0036] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
