[0033] The following is a description of the implementation of the present invention by specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] like Figures 1 to 7 As shown, the present invention provides a thermometer auxiliary bracket for convenient temperature measurement in a cable trench, comprising an inner rod 1 and an outer rod 2 sleeved on the inner rod 1, a mounting plate 3 for mounting a thermometer is rotatably connected to the bottom of the outer rod 2, a guide block 9 is further provided on the outer rod 1, and a guide groove 10 corresponding to the guide block 9 is opened on the outer wall of the inner rod 2, when the guide block 9 cooperates with the guide groove 10, the inner rod 1 can be restricted to avoid the problem that the inner rod 1 will rotate in the outer rod 2, and the inner rod 1 is a hollow structure, when in use, sufficient cables connected to the thermometer can be reserved in the inner rod 1, so that the detected data information can be observed in real time through an external display device when in use.

[0035] Cable fixings 5 ​​connected to the mounting plate 3 via a pull rope 4 are correspondingly arranged on both sides of the outer rod 2. A control component 6 connected to the cable fixings 5 ​​via a pull rope 4 and used to control the movement of the mounting plate 3 is arranged at one end of the inner rod 1 away from the mounting plate 3. The pull rope 4 is preferably made of nylon to ensure that it has sufficient strength. A plurality of guide cylinders 8 for guiding the pull rope 4 are arranged on the outer rod 2.

[0036] In actual use, arc grooves corresponding to the pull rope 4 can be opened on the outer rod and the inner rod, and the guide tube 8 is placed in the arc groove to confine the pull rope 4 in the arc groove to protect the pull rope 4.

[0037] like Figure 1 and Figure 3 As shown, the cable fixing member 5 includes a sliding groove 501 opened on the side wall of the outer rod 2, a sliding block 502 slidably connected to the outer rod 2 through the sliding groove 501, a first guide roller 503 is fixedly installed on the sliding block 502, and a second guide roller 504 is arranged at the end of the outer rod 2 away from the mounting plate 3, the pull rope 4 connected to the mounting plate 3 is wound from the second guide roller 504 to the first guide roller 503 and connected to the control component 6, and an elastic rope connected to the side wall of the sliding groove 502 close to the mounting plate is arranged at the end of the sliding block 502 close to the mounting plate 3, so as to ensure that when the inner rod 1 is pulled to adjust its relative position with the outer rod 2, the pull rope 4 connected thereto can always remain in a taut state under the action of the elastic rope, so as to avoid the problem that the pull rope 4 will be separated from the first guide roller 503 or the second guide roller 504 during adjustment.

[0038] The overall working process of the cable fixing is as follows: pulling the inner rod 1 to adjust the relative position of the inner rod 1 and the outer rod 2 will increase the overall length, and in this process, the distance between the first guide roller 503 and the second guide roller 504 will be adjusted by the movement of the sliding block 502, so that a certain length of pull rope can be reserved to make up for the length difference between the inner rod 1 and the outer rod 2 before and after the adjustment, so as to realize the normal connection between the mounting plate 3 and the control component 6 through the pull rope 4.

[0039] like Figure 1 , Figure 4 and Figure 7As shown, in order to avoid the problem that when the control component 6 drives the mounting plate 3 to move through the pull rope 4, the cable fixing member 5 can still be used to retract and release the wire, resulting in the inability to complete the control of the mounting plate 3, the cable fixing member 5 provided also includes a protective cover 505 fixed to the side wall of the outer rod 2 and corresponding to the sliding groove 501, and a first fixing component 506 provided on the sliding block 502 for fixing the position of the sliding block 502. The first fixing component 506 includes a mounting block 507 and a slidably connected to the mounting block 507 and used to support the protective cover 505 to fix the position of the sliding block 502 The fixed block 508 is fixed, and a groove for the pull rope 4 to pass through is opened on the fixed block 508 to ensure that the fixed block 508 will not press the pull rope 4 when it is against the protective cover 505, which will cause the pull rope 4 to be easily damaged during long-term use. Both sides of the mounting block 507 are slidably connected with a pushing block 509 for pushing the fixed block 508 to move. The protective cover 505 is arranged on the first guide roller 503 and the second guide roller 504 to protect it, so as to avoid it from colliding with other objects such as cables in the cable trench during use, which may cause the device to be easily damaged.

[0040] It should be added that the corresponding ends of the pushing block 509 and the fixed block 508 are both inclined structures, that is, after adjusting the relative positions of the inner rod 1 and the outer rod 2, the first fixing component 506 can be used to fix the current state of the pull rope 4. When in use, the pushing block 509 can be pressed first, and the pushing block 509 can squeeze the fixed block 508 to move. After the fixed block 508 moves to a certain position, it can support the inner wall of the protective cover 505, and the mutual squeezing force between the fixed block 508 and the protective cover 505 can fix the position of the sliding block 502. In addition, in order to make it more firmly fixed, the inner wall of the protective cover 505 is provided with an anti-slip pattern, and the fixed block is provided with a corresponding anti-slip pad, which can greatly increase the friction between the sliding block 502 and the protective cover 505 when pressurized against each other, and the fixation is more secure.

[0041] A first limiting rubber ring 510 is provided on the pushing block 509, and a second limiting rubber ring 511 corresponding to the first limiting rubber ring 510 is provided on the mounting block 507. When the pushing block 509 is pressed, the first limiting rubber ring 510 will be driven to move. When the pushing block 509 moves to a certain extent, a certain force needs to be applied to make the first limiting rubber ring 510 pass over the second limiting rubber ring 511, and then the position of the pushing block 509 is fixed by the second limiting rubber ring 511. When the pushing block 509 is pulled out, it is also necessary to apply a force to make the first limiting rubber ring 510 pass over the second limiting rubber ring 511, which will be more convenient for fixing the pushing block 509.

[0042] like Figure 1 , Figure 2 and Figure 6 As shown, the control assembly 6 includes a grip rod 601 which is arranged at one end of the inner rod 1 away from the mounting plate 3 and is a U-shaped structure, and limiting slide grooves 602 are opened on both sides of the inner rod 1. The inner sides of both ends of the grip rod 601 are slidably connected with adjustment rods 603, and the end of the adjustment rod 603 away from the grip rod 601 is slidably connected to the inner rod 1. The upper and lower sides of the end of the adjustment rod 603 away from the grip rod 601 are provided with limiting springs 605 placed in the limiting slide groove 602. Under the action of the two limiting springs 605, the position of the adjustment rod 603 can be fixed at the middle position of the limiting slide groove 602 for subsequent adjustment. A pull ring 6 for the pull rope 4 is also provided on the adjustment rod 603. 04, the control component 6 is connected to the mounting plate 3 through the pull rope 4 fixed to the adjusting rod 603 and passing through the cable fixing part 5. When adjusting the angle of the mounting plate 3, one of the adjusting rods 603 needs to be lifted by hand. The lifting of the adjusting rod 603 will drive the movement of the pull rope 4, and then the movement of the mounting plate 3 can be realized through the pull rope 4. At the same time, the other side of the mounting plate will drive the other adjusting rod 603 to move through the pull rope 4. When resetting, the other adjusting rod 603 can be used under the action of the limit spring 602 to drive the mounting plate 3 to reset through the pull rope 4. When adjusting the angle of the thermometer placed on the mounting plate 3, the adjustment will be more convenient.

[0043] like Figure 2 and Figure 5 As shown, it also includes a second fixing component 7 for fixing the relative position of the inner rod 1 and the outer rod 2. The second fixing component 7 includes a plurality of fixing grooves 701 equidistantly provided on the inner rod 1 and through holes 702 corresponding to the fixing grooves 701 and provided on the outer rod 2. A fixing rod 703 engaged with the fixing groove 701 is rotatably connected to one side of the through hole 702 through a torsion spring. The second group of fixing members 7 is provided to ensure the stability of the support for the thermometer after the length of the device is adjusted. When in use, to adjust the relative position of the inner rod 1 and the outer rod 2, it is necessary to first press the fixing rod 703 to disengage the fixing rod 703 from the engagement with the fixing groove 701, so that the inner rod 1 can move freely in the outer rod 2, so that the user can adjust the length according to his or her own height. Similarly, when shrinking, it is also necessary to press the fixing rod 703 to disengage the fixing rod 703 from the engagement with the fixing groove 701. After shrinking, the space occupied by the device can be greatly reduced, and it will be more convenient to carry it out.

[0044] The two cable fixings 5 ​​are symmetrically arranged about the center axis of the outer rod 2. In addition, the two connection points connected to the mounting plate 3 by the pull rope 4 are also symmetrically arranged about the center axis of the outer rod 2, ensuring that when the mounting plate 3 is rotated by the pull rope 4, it can rotate more easily.

[0045] Although the present invention has been described in detail above by general description and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the present invention. Therefore, these modifications or improvements made without departing from the spirit of the present invention all belong to the scope of protection claimed by the present invention.
