[0028] The embodiments of this utility model will be further described below with reference to the accompanying drawings.
[0029] Example:
[0030] like Figures 1-6 As shown, a reamer with a protective structure includes a reamer body 1, a fixed limiting mechanism 2 fixedly sleeved on the outer surface of the reamer body 1, and a movable protective mechanism 3 movably sleeved on the outer surface of the reamer body 1.
[0031] The working principle of the above technical solution is as follows:
[0032] During use, the movable protective mechanism 3 is fitted onto the outer surface of the reamer body 1 and is in close contact with the fixed limiting mechanism 2. Then, the movable protective mechanism 3 is adjusted and connected to the fixed limiting mechanism 2, which can stably protect the reamer body 1 and prevent damage to the reamer body 1. The operation is convenient and quick.
[0033] In another embodiment, such as Figure 3 As shown, the fixed limiting mechanism 2 includes a fixed mounting collar 21, and a fixed limiting collar 22 is symmetrically provided on the side of the fixed mounting collar 21 away from the machining part of the reamer body 1.
[0034] The end of the movable protective mechanism 3 can be squeezed and connected to the fixed installation collar 21 to ensure the connection is sealed, and at the same time it can be connected to the fixed limiting collar 22, so as to ensure a stable connection and installation of the movable protective mechanism 3 and convenient operation.
[0035] In another embodiment, such as Figure 4 As shown, the movable protective mechanism 3 includes a protective sleeve 31. A sealing ring 32 is fixedly provided on the side of the protective sleeve 31 near the fixed mounting ring 21. A fixed guide frame 33 is symmetrically provided on the outer surface of the protective sleeve 31. A fixed guide groove 34 is opened on the surface of the fixed guide frame 33. A movable mounting block 35 is movably connected to the inner side of the fixed guide groove 34. A fixed positioning block 36 is symmetrically provided on the surface of the movable mounting block 35. A movable mounting arm 37 is movably sleeved on the outer surface of the fixed positioning block 36. A connecting mounting block 38 is fixedly connected to the inner side of the other end of the movable mounting arm 37. A connecting insert block 39 is fixedly connected to the side of the connecting mounting block 38 near the movable mounting arm 37. A connecting pull assembly 310 is fixedly connected to one end of the movable mounting block 35. A connecting drive assembly 311 is fixedly connected to the end of the protective sleeve 31 away from the fixed mounting ring 21.
[0036] The protective sleeve 31 is easily fitted onto the outer side of the end surface of the reamer body 1, so that the sealing ring 32 and the fixed mounting ring 21 fit together. Then, the movable mounting arm 37 is deflected, which drives the connecting mounting block 38 and the connecting insert block 39 to deflect and adjust, so that the connecting insert block 39 can move to the end of the fixed limiting ring 22. Next, the connecting drive assembly 311 is adjusted, which causes the connecting pull assembly 310 to move, driving the movable mounting block 35, the fixed positioning block 36, the movable mounting arm 37, the connecting mounting block 38, and the connecting insert block 39 to move, so that the connecting insert block 39 can be inserted into the inner side of the fixed limiting ring 22. At the same time, the connecting mounting block 38 squeezes the end of the fixed limiting ring 22, so that the fixed mounting ring 21 and the protective sleeve 31 squeeze and fit the sealing ring 32, thereby achieving stable sealing protection. The operation is convenient and quick.
[0037] In another embodiment, such as Figure 4 As shown, the fixed positioning block 36 has a T-shaped cross-section, and the outer side of the movable mounting block 35 slides and fits against the inner side of the fixed guide groove 34.
[0038] The movable mounting arm 37 can be stably deflected and adjusted on the outer side of the fixed positioning block 36, making operation convenient.
[0039] In another embodiment, such as Figure 5 As shown, the connection drive assembly 311 includes a connection mounting bracket 3101, a threaded mounting sleeve 3102 is fixedly connected to one side of the connection mounting bracket 3101, and a through hole is provided in the middle of one side of the connection mounting bracket 3101.
[0040] When the drive assembly 311 rotates, the threaded mounting sleeve 3102 can move, which in turn moves the mounting bracket 3101 and the movable mounting block 35, thereby enabling adjustment.
[0041] In another embodiment, such as Figure 6 As shown, the connection drive assembly 311 includes a connection sleeve block 3111, a movable mounting plate 3112 is movably connected inside the connection sleeve block 3111, a connection threaded rod 3113 is fixedly connected to one side of the movable mounting plate 3112, and a rotating end plate 3114 is fixedly connected to the other end of the connection threaded rod 3113.
[0042] The rotating end plate 3114 is convenient to rotate, which drives the connecting threaded rod 3113 and the movable mounting plate 3112 to rotate. This allows the movable mounting plate 3112 to rotate stably inside the connecting sleeve block 3111. At the same time, when the connecting threaded rod 3113 rotates, it can move the threaded mounting sleeve 3102, which in turn moves the connecting mounting bracket 3101 and the movable mounting block 35, thereby enabling connection adjustment and convenient operation.
[0043] In another embodiment, such as Figure 6 As shown, the outer surface of the connecting threaded rod 3113 is in contact with the inner side of the threaded mounting sleeve 3102, and the connecting threaded rod 3113 is in slidable contact with the inner side of the through hole in the middle of one side of the connecting mounting bracket 3101.
[0044] When the threaded rod 3113 rotates, the threaded mounting sleeve 3102 can move stably on the outer side of the surface of the threaded rod 3113, while the threaded rod 3113 can rotate stably on the inner side of the mounting bracket 3101, making operation convenient.
[0045] The working principle of this utility model is as follows: During use, the protective sleeve 31 is first fitted onto the outer end of the reamer body 1, so that the sealing ring 32 and the fixed mounting ring 21 are in contact. Then, the movable mounting arm 37 is deflected, causing the connecting mounting block 38 and the connecting insert block 39 to deflect and adjust, allowing the connecting insert block 39 to move while fixing the end of the limiting ring 22. Next, the end plate 3114 is rotated, causing the connecting threaded rod 3113 and the movable mounting plate 3112 to rotate, allowing the movable mounting plate 3112 to rotate stably inside the connecting sleeve 3111. Simultaneously, the connecting threaded rod... When the threaded rod 3113 rotates, it causes the threaded mounting sleeve 3102 to move, which in turn moves the connecting mounting bracket 3101, the movable mounting block 35, the fixed positioning block 36, the movable mounting arm 37, the connecting mounting block 38, and the connecting insert block 39. This allows the connecting insert block 39 to be inserted into the inner side of the fixed limiting collar 22. At the same time, the connecting mounting block 38 presses the end of the fixed limiting collar 22, causing the fixed mounting collar 21 and the protective sleeve 31 to press and fit the sealing ring 32, thereby achieving stable sealing protection. The overall structure is simple and the operation is convenient and quick.
[0046] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
