When the user needs to monitor the temperature of the battery, the clamping plate 14 is pulled to release the clamping column 15, and then the toggle plate 12 is moved upward to release the limit of the L-shaped block 4. At this time, the clamping plate 6 is moved to a position suitable for placing the battery, and the control mechanism 2 is started to enable the temperature sensor 8 to monitor the temperature of the battery. The easy-to-adjust clamping plate 6 can save time and effort for the staff when adjusting the device, thereby improving the work efficiency of the staff.
[0025] Reference Figure 4 As shown, in this embodiment: a first slide groove 18 is provided at the front end and the rear end inside the traction groove 10, a first slider 19 is fixed at the front end and the rear end of the traction block 11, and the interior of the first slide groove 18 is slidably connected to the first slider 19. Through the arrangement of the first slide groove 18 and the first slider 19, a stable limiting effect can be formed when the toggle plate 12 moves in the toggle groove 9, thereby preventing the limit rod 13 from being unable to be inserted into the second slot 17 due to deviation, thereby affecting the normal fixation of the clamping plate 6.
[0026] Reference Figure 4 As shown, in the present embodiment: the surface of the limit rod 13 is slidably connected with a first return spring 20, one end of the first return spring 20 close to the toggle plate 12 is fixedly connected to the toggle plate 12, and one end of the first return spring 20 away from the toggle plate 12 is fixedly connected to the inside of the toggle groove 9. Through the setting of the first return spring 20, when the toggle plate 12 is released from the limit, the elastic force stored in the first return spring 20 drives the limit rod 13 to pop out quickly from the inside of the second slot 17, thereby realizing the rapid release of the limit of the L-shaped block 4.
[0027] Reference Figure 2As shown, in this embodiment: a second slide groove 21 is provided at the top and bottom ends of the L-shaped groove 3, a second slider 22 is fixed at the top and bottom ends of the L-shaped block 4, and the interior of the second slide groove 21 is slidably connected to the second slider 22. Through the arrangement of the second slide groove 21 and the second slider 22, the L-shaped block 4 can be made more stable during the movement, thereby significantly improving the adjustment stability of the clamping plate 6.
[0028] Reference Figure 5 As shown, in this embodiment: a second return spring 23 is installed at one end of the L-shaped block 4 away from the clamping plate 6, and the end of the second return spring 23 away from the L-shaped block 4 is fixed inside the L-shaped groove 3. Through the setting of the second return spring 23, the clamping plate 6 can be quickly reset after use, which is convenient for the staff to use next time.
[0029] Reference Figure 6 As shown, in this embodiment: a mounting groove 24 is provided inside the mounting plate 7, and the interior of the mounting groove 24 is slidably connected with the temperature sensor 8, and a pressing groove 25 is provided at the front end and the rear end of the temperature sensor 8, and an elastic spring 26 is installed inside the pressing groove 25, and a pop-up groove 27 is provided at the front end and the rear end of the mounting plate 7, and a pressing block 28 is installed at one end of the elastic spring 26 close to the mounting plate 7, and the pressing block 28 is slidably connected with the inside of the pop-up groove 27. When the staff needs to remove the temperature sensor 8 for inspection and maintenance, the pressing block 28 is pressed inward to release the limit of the temperature sensor 8. At this time, the temperature sensor 8 is removed for replacement, and the temperature sensor 8 is put back after completion. At this time, the elastic force stored in the elastic spring 26 is released to drive the pressing block 28 to pop out from the pop-up groove 27, so that the temperature sensor 8 is limited, thereby achieving rapid replacement when a failure of the temperature sensor 8 occurs.
[0030] Reference Figure 7 As shown, in this embodiment: a third slide groove 29 is provided at the top and bottom ends of the mounting plate 7, a third slider 30 is fixed at the top and bottom ends of the temperature sensor 8, and the inside of the third slide groove 29 is slidably connected to the third slider 30. Through the arrangement of the third slide groove 29 and the third slider 30, the temperature sensor 8 can be more convenient to disassemble and install, thereby improving the replacement efficiency of the temperature sensor 8.
[0031] Working principle: when the user needs to monitor the temperature of the battery, the clamping plate 14 is pulled to release the clamping connection with the clamping column 15, and then the toggle plate 12 is moved upward to release the limit of the L-shaped block 4. At this time, the clamping plate 6 is moved to a position suitable for the battery placement, and the control mechanism 2 is started to enable the temperature sensor 8 to monitor the temperature of the battery. The easy-to-adjust clamping plate 6 can save time and effort for the staff when adjusting the device, thereby improving the work efficiency of the staff. Through the setting of the first slide groove 18 and the first slider 19, the toggle plate 12 can form a stable limiting effect when moving in the toggle groove 9 to prevent the limit rod 13 from being unable to be inserted into the second slot 17 due to offset, thereby affecting the normal fixation of the clamping plate 6. Through the setting of the first return spring 20, when the toggle plate 12 is released from the limit, the elastic force stored in the first return spring 20 drives the limit rod 13 to quickly pop out from the inside of the second slot 17, thereby realizing the L-shaped block 4. The limit is quickly released. By setting the second slide groove 21 and the second slider 22, the L-shaped block 4 can be made more stable during the movement, thereby significantly improving the adjustment stability of the clamping plate 6. By setting the second return spring 23, the clamping plate 6 can be quickly reset after use, which is convenient for the staff to use next time. When the staff needs to remove the temperature sensor 8 for inspection and maintenance, the pressing block 28 is pressed inward to release the limit of the temperature sensor 8. At this time, the temperature sensor 8 is removed for replacement. After completion, the temperature sensor 8 is put back. At this time, the elastic force stored in the elastic spring 26 is released to drive the pressing block 28 to pop out of the pop-up slot 27, so that the temperature sensor 8 is limited, thereby achieving rapid replacement of the temperature sensor 8 when a fault occurs. By setting the third slide groove 29 and the third slider 30, the temperature sensor 8 can be more convenient during the disassembly and installation process, thereby improving the replacement efficiency of the temperature sensor 8.
