Description

Technical Field

[0001] The utility model relates to the technical field of sensors, in particular to a temperature and humidity sensor for a power distribution cabinet. Background Art

[0002] The temperature and humidity sensors on the distribution cabinet mostly use integrated temperature and humidity probes as temperature measuring elements to collect temperature and humidity signals. After voltage stabilization and filtering, operational amplification, nonlinear correction, V / I conversion, constant current and reverse protection and other circuit processing, they are converted into current signals or voltage signals that are linearly related to temperature and humidity for output. Temperature and humidity sensors are widely used in various fields of production and life due to their small size and stable performance.

[0003] When installing, most existing temperature and humidity sensors are directly fixed to the designated position of the distribution cabinet by screws. When the temperature and humidity sensors need to be replaced or repaired, the screws need to be frequently disassembled, which easily leads to the risk of the screws being stripped, and the process of disassembling and assembling the screws takes a long time.

[0013] (III) Beneficial effects

[0014] Compared with the prior art, the utility model provides a temperature and humidity sensor for a power distribution cabinet, which has the following beneficial effects:

[0015] The temperature and humidity sensor of the power distribution cabinet can position the limit plate on the fixed seat through the cooperation of the positioning block and the groove.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4 The utility model is a temperature and humidity sensor for a power distribution cabinet, comprising a base plate 1 and a sensor body 2, wherein a fixing seat 4 is fixedly arranged at the upper end of the base plate 1, a limiting plate 3 is fixedly arranged at the lower end of the sensor body 2, a plurality of grooves are arranged at the upper end of the fixing seat 4, a plurality of positioning blocks 5 cooperating with the grooves are arranged at the lower end of the limiting plate 3, two positioning grooves 11 are symmetrically arranged on both sides of the limiting plate 3, a plurality of empty grooves 7 are symmetrically arranged on both sides of the positioning groove 11, a first spring 8 is fixedly arranged inside the empty groove 7, two symmetrical positioning grooves 11 are arranged on both sides of the fixing seat 4, and a plurality of positioning grooves 11 are arranged on both sides of the fixing seat 4. A cross bar 9, two ends of the cross bar 9 are provided with positioning rods 6 inserted into the empty slot 7 and connected to one end of the first spring 8, a driven rod 14 is fixedly arranged at the outer end of the positioning rod 6, and positioning seats 16 are fixedly arranged at the four corners of the bottom plate 1, and a driving wheel 15 is rotatably arranged on the positioning seat 16, and the driving wheel 15 is located at the lower end of the driven rod 14, and the driving wheel 15 is meshed with the driven rod 14, and a clamping rod 17 is fixedly arranged at one end of the driving wheel 15 away from the positioning seat 16, and a clamping block 18 for limiting the limit plate 3 is provided at one end of the clamping rod 17;

[0024] When the structure is in use, the bottom plate 1 is fixed to the designated position of the power distribution cabinet by screws, and the positioning block 5 cooperates with the groove to position the limit plate 3 on the fixing seat 4. At this time, the first spring 8 is in a stretched state, which can provide a pulling force to the positioning rod 6, so that the clamping block 18 can provide a pressure to the limit plate 3, thereby making the sensor body 2 more firmly installed on the fixing seat 4;

[0025] When the sensor body 2 needs to be disassembled, pulling the cross bar 9 can make the positioning rod 6 continue to stretch the first spring 8. At this time, the driving wheel 15 can drive the clamping rod 17 to rotate through the meshing effect. At this time, the clamping rod 17 drives the clamping block 18 to rotate, and the clamping block 18 can be separated from the limit plate 3, so that the sensor body 2 can be taken on the fixed seat 4. The structure is simple and the operation is convenient. This process does not require repeated operation of screws, which not only makes the sensor body 2 more convenient during assembly and disassembly, but also avoids screw stripping.

[0026] Furthermore, the clamping rod 17 can be an arc-shaped structure, and the clamping block 18 can be a cylindrical structure.

[0027] The lack of a limiting structure at the cross bar 9 will affect the stability of the clamping block 18 when clamping the limiting plate 3. A slot is provided on the inner wall of the positioning groove 11, and a positioning plate 10 is inserted into the positioning groove 11 in the middle part of the cross bar 9. A cavity is provided on both sides of the positioning plate 10, and a second spring 13 is provided inside the cavity. One end of the second spring 13 is provided with a clamping block 12 that cooperates with the slot. When the clamping block 18 limits the limiting plate 3, the positioning plate 10 is inserted into the positioning groove 11. At this time, the clamping block 12 cooperates with the slot to provide a limiting structure for the cross bar 9, which can improve the stability of the clamping block 18 when clamping the limiting plate 3. When the pulling force provided to the cross bar 9 is greater than the elastic force of the second spring 13, the clamping block 12 can compress the second spring 13, so that the clamping block 12 can be disengaged from the slot, thereby allowing the positioning plate 10 to be pulled out of the positioning groove 11.

[0028] Furthermore, two slots may be provided on the inner wall of the positioning slot 11 .

[0029] Furthermore, the card slot and the card block 12 may both be trapezoidal structures.

[0030] Furthermore, the clamping block 18 is made of rubber, and the clamping rod 17 is made of metal, and the clamping rod 17 can be made of aluminum alloy.
