[0023] 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 are within the protection scope of this utility model.

[0024] Example 1

[0025] Reference Figure 1 and Figure 2 One embodiment of this utility model is a roller sensor fixing bracket, including a roller end cover 1. The outer wall of the roller end cover 1 is threaded with a positioning bolt 2. The outer wall of the positioning bolt 2 is threaded with a fixing component 3. The outer wall of the fixing component 3 is fixedly connected with a locking component 4. The outer wall of the locking component 4 is fixedly connected with a sensor housing 5. The sensor is fitted inside the sensor housing 5.

[0026] Specifically, according to the design drawings, the fixing component 3 is cut into a predetermined shape using a cutting machine. The locking component 4 and the sensor housing 5 are bolted to the fixing component 3. Mounting holes corresponding to the positioning bolts 2 are opened on the fixing component 3. The internal structure of the sensor housing 5 is machined to ensure that the sensor can slide and lock. Then, the temperature vibration sensor is placed in the sensor housing 5. The fixing component 3 is aligned with the hole in the roller end cover 1 and tightened with the positioning bolts 2. The installation is checked for firmness, and the sensor power is turned on for testing.

[0027] Positioning bolt 12 includes a fixing bracket 301. The inner wall of fixing bracket 301 is threadedly connected to the outer wall of positioning bolt 12. Positioning bolt 22 is attached to the outer wall of fixing bracket 301. Positioning bolt 303 is threadedly connected to the inner wall of fixing bracket 301. Fixing bracket 24 is threadedly connected to the outer wall of positioning bolt 303. The outer wall of fixing bracket 2304 is fixedly connected to the outer wall of locking assembly 4. Fixing bracket 1301 and fixing bracket 2304 are both made of galvanized material, and sensor housing 5 is also made of galvanized material. The outer wall of fixing bracket 1301 is slidably connected to the outer wall of fixing bracket 2304. The outer wall of fixing bracket 1301 is attached to the outer wall of roller end cover 1.

[0028] Specifically, when needed, first, attach the sensor housing 5 to the roller end cover 1. At this time, the fixing bracket 304 is also attached to the roller end cover 1. The sensor housing 5 fits onto the sensor, serving to fix and protect it. Then, stretch the fixing bracket 301 until the hole in the fixing bracket 301 corresponds to the hole in the roller end cover 1. Use the positioning bolt 2 to fix the fixing bracket 301 to the roller end cover 1. The positioning bolt 2 is a matching bolt for the roller end cover 1, and the hole in the fixing bracket 301 is compatible with the positioning bolt 2. Then, tighten the positioning bolts 302 and 303 respectively. At this point, due to the... Both the second positioning bolt 302 and the third positioning bolt 303 have washers underneath, which allow the second positioning bolt 302 and the third positioning bolt 303 to fix the middle and bottom positions of the first fixing bracket 301 and the second fixing bracket 304 respectively, thereby fixing the whole. The stabilization of the second fixing bracket 304 of the fixing component 3 stabilizes the locking component 4, which in turn stabilizes the sensor housing 5. This achieves the effect of avoiding sensor damage caused by improper fixing method and reducing maintenance costs. In addition, both the first fixing bracket 301 and the second fixing bracket 304 are made of common galvanized materials, with simple processing structure and low cost, which is lower than the cost of frequent sensor replacement.

[0029] Please see the appendix Figure 2 The locking assembly 4 includes a positioning ring 401. The outer wall of the positioning ring 401 is fixedly connected to the outer wall of the fixed bracket 304. The internal thread of the positioning ring 401 is connected to a locking bolt 402. The outer wall of the locking bolt 402 is rotatably connected to an adhesive piece 403. The outer wall of the adhesive piece 403 is attached to the outer wall of the sensor housing 5. The outer wall of the positioning ring 401 is attached to the outer wall of the roller end cover 1, and the outer wall of the sensor housing 5 is attached to the outer wall of the roller end cover 1.

[0030] Specifically, when the sensor housing 5 is placed inside the locking assembly 4, the locking bolt 402 is rotated first. Since the locking bolt 402 is bolted to the positioning ring 401, the locking bolt 402 rotates and drives the fastening piece 403 to move, causing the outer side of the fastening piece 403 to fit against the outer wall of the sensor housing 5. The fastening piece 403 is restricted by the sensor housing 5 and the positioning ring 401, so that the fastening piece 403 will not rotate, thereby making the sensor housing 5 more stable and improving the overall service life.

[0031] Example 2

[0032] Please see the appendix Figure 3 The fixing component 3 includes a protective sleeve 305, the inner thread of which is connected to the outer wall of the positioning bolt 2, the inner wall of which is slidably connected to an extension plate 306, the inner thread of which is connected to a positioning bolt 303, and the outer wall of the positioning bolt 303 is fixedly connected to an anti-slip plate 307.

[0033] Specifically, in this embodiment, the protective sleeve 305 is stretched, causing the extension plate 306 to gradually slide out from the inside of the protective sleeve 305. The protective sleeve 305 is fixed to the roller end cover 1 by the positioning bolt 2. Then, the positioning bolt 303 is rotated to cause the positioning bolt 303 and the anti-slip plate 307 to move forward synchronously, so that the anti-slip plate 307 and the surface of the extension plate 306 are in contact. At this time, due to the friction between the anti-slip plate 307 and the extension plate 306, the anti-slip plate 307 fixes the extension plate 306. In this embodiment, by placing the extension plate 306 inside the protective sleeve 305, the extension plate 306 and the protective sleeve 305 can be shortened, thus reducing the floor space occupied.

[0034] Example 3

[0035] Please see the appendix Figure 4 The locking assembly 4 includes a positioning plate 404, the outer wall of which is fixedly connected to the outer wall of the fixing assembly 3. A connecting plate 405 is slidably connected to the inner wall of the positioning plate 404. A fixing bolt 406 is threadedly connected to the inner wall of the connecting plate 405. A semi-ring 407 is fixedly connected to the lower surface of the connecting plate 405. The outer wall of the semi-ring 407 is in contact with the sensor housing 5.

[0036] Specifically, in this embodiment, the sensor housing 5 can be placed between the two semi-rings 407. Then, the upper and lower fixing bolts 406 are rotated respectively. The fixing bolts 406 are provided with two reverse threads, which causes the connecting plates 405 on both sides to move towards the center. This causes the semi-rings 407 on both sides to clamp and fix the sensor housing 5. The positioning plate 404 restricts the connecting plate 405 to prevent the connecting plate 405 from flipping during movement. In this example, by dividing the semi-rings 407 into two, it is possible to adapt to sensor housings 5 ​​of different sizes, thus improving the overall adaptability.

[0037] Working principle: When needed, first attach the sensor housing 5 to the roller end cover 1, and align the position of the tension fixing bracket 301 with the hole on the roller end cover 1. Use positioning bolt 2 to fix the fixing bracket 301 to the roller end cover 1. Then tighten positioning bolt 302 and positioning bolt 303 respectively to fix the middle and bottom positions of fixing bracket 301 and fixing bracket 304 respectively, thereby stabilizing the sensor housing 5. This avoids sensor damage caused by improper fixing and reduces maintenance costs. In addition, fixing bracket 301 and fixing bracket 304 are made of common galvanized materials, with simple processing structure and low cost, which is lower than the cost of frequent sensor replacement.

[0038] When the sensor housing 5 is placed inside the locking assembly 4, rotating the locking bolt 402 causes the fastening piece 403 to move, causing the outer wall of the fastening piece 403 to fit against the outer wall of the sensor housing 5, thereby making the sensor housing 5 more stable and improving its overall service life.

[0039] This bracket not only avoids sensor damage caused by improper fixing and reduces maintenance costs, but also uses common galvanized materials, has a simple processing structure, and is inexpensive, lower than the cost of frequent sensor replacements. Finally, it makes the sensor housing 5 more stable and improves the overall service life.

[0040] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
