Description

Technical Field

[0001] This utility model relates to the field of temperature and humidity sensor technology, and in particular to a temperature and humidity sensor with a detachable housing. Background Technology

[0002] Temperature and humidity sensors typically use integrated temperature and humidity probes as the sensing element. They collect temperature and humidity signals, which are then processed by circuits such as voltage regulation and filtering, operational amplification, nonlinear correction, V / I conversion, constant current and reverse protection. The processed signals are then converted into current or voltage signals that are linearly related to temperature and humidity. Alternatively, they can be directly output via interfaces such as 485 or 232 through the main control chip. However, if the temperature and humidity sensor malfunctions during subsequent use, the user will need to open the casing and inspect and maintain the internal components.

[0003] A search revealed that the Chinese patent "A Sensor Housing for Easy Disassembly" (publication number CN212539222U) includes a bottom shell. Two symmetrical fixing plates are slidably disposed within the inner cavity of the bottom shell. A buffer spring is provided between the surface of the fixing plates and the inner wall of the bottom shell. A groove is provided on the top of the bottom shell, and multiple slots are formed on the surface of the groove. A shell cover is snapped into place inside the groove. The shell cover includes a top plate, and a cooling fan is provided near the center of the top plate surface. A sealing plate is provided at the bottom of the top plate. Multiple locking blocks are slidably arranged on the outer wall, and the locking blocks are adapted to the inside of the locking groove. By setting the bottom shell and the shell cover to lock together, during disassembly, it is only necessary to press the locking block to make the locking block slide into the sliding groove and disengage from the groove. Then, the top plate can be pulled to remove the sealing plate from the groove, which facilitates the subsequent maintenance and replacement of the sensor body. However, the above method has the following drawbacks in actual use: although the shell cover can be quickly disassembled and assembled, after the shell cover is removed, the bottom shell still obstructs the sensor on multiple sides, making the inspection and maintenance of the sensor inconvenient. Utility Model Content

[0004] Therefore, it is necessary to provide a temperature and humidity sensor with a detachable housing to address the problem that the bottom shell obstructs the outside of the sensor, causing inconvenience in inspection and maintenance.

[0005] A temperature and humidity sensor with a detachable housing includes a sensor body and a housing mounted on its outer side; the housing consists of a base plate and four side plates, the sides of which are connected to the base plate via hinges; it also includes a disassembly mechanism, which is located on the outside of the sensor body and is used to quickly disassemble the housing, reducing obstruction to the sensor body after disassembly; wherein, the disassembly mechanism includes a set of inserts and a top cover, one side of each side plate is inserted into the interior of the top cover, one side of each insert is slidably connected to the interior of the top cover, and the other side of each insert is inserted into the interior of the side plate.

[0006] In one embodiment, the base plate has two slidingly connected mating blocks inside, and the mating blocks are connected to the sensor body by bolts.

[0007] In one embodiment, the top of the cover is provided with a vertically movable pull ring, and a traction rope is provided between the pull ring and the insert block.

[0008] In one embodiment, one corner of the insert is chamfered.

[0009] In one embodiment, two springs are provided on the outer side of the insert, with one end of each spring attached to the inside of the top cover.

[0010] In one embodiment, four strip grooves are provided on one side of the top cover, and the strip grooves are adapted to the shape of the side plate.

[0011] In one embodiment, a set of wire harness slots is provided on the other side of the top cover.

[0012] Beneficial effects

[0013] 1. By setting the top cover and the plug, the user can pull the pull ring and the traction rope will separate the drive plug from the corresponding side plate. Then the top cover can be removed and the side plate at the corresponding point can be gradually flattened, reducing the phenomenon of multiple sides of the sensor being blocked, which facilitates subsequent inspection and maintenance work.

[0014] 2. By setting a sliding docking block, after the outer shell is disassembled, the user can move the sensor body so that the probe and the connecting end move together, which makes it easier for the side plate of the probe end to tilt, increasing the exposed area of ​​the sensor body and facilitating inspection and maintenance.

[0027] The following is combined Figures 1-4 This invention describes a temperature and humidity sensor with a detachable housing.

[0028] In one embodiment, a temperature and humidity sensor with a detachable housing includes a sensor body 100 and a housing mounted on its outer side; the housing consists of a base plate 120 and four side plates 110, the sides of the side plates 110 being connected to the base plate 120 via hinges; it also includes a disassembly mechanism 200, which is disposed on the outer side of the sensor body 100 and is used to quickly disassemble the housing, reducing obstruction to the sensor body 100 after disassembly; wherein, the disassembly mechanism 200 includes a set of inserts 210 and a top cover 220, one side of the side plate 110 being inserted into the interior of the top cover 220, one side of the inserts 210 being slidably connected to the interior of the top cover 220, and the other side of the inserts 210 being inserted into the interior of the side plate 110.

[0029] like Figure 2 As shown, the base plate 120 has two sliding connections inside, and the connecting blocks are connected to the sensor body 100 by bolts.

[0030] In this embodiment, when the sensor body 100 needs to be disassembled for maintenance, the user can drive the plug 210 to separate from the corresponding side plate 110, and then remove the top cover 220 directly. Then, rotate the three side plates 110 of the sensor body 100 along the bottom plate 120 to flatten them. Next, the user can slide the sensor body 100 to separate its probe and cable connection end from the remaining side plate 110. Then, the remaining side plate 110 can be flattened. At this time, the top and four sides of the sensor body 100 are unobstructed, which is convenient for the user to carry out maintenance work.

[0031] It should be noted that one of the side panels 110 is equipped with a probe protection box, a heat dissipation grille and a wiring harness connection port. During disassembly, the wiring harness in the wiring harness connection port does not affect the flattening of the side panel 110.

[0032] like Figure 2 and Figure 4 As shown, the top of the top cover 220 is provided with a vertically movable pull ring 221, and a traction rope 222 is provided between the pull ring 221 and the insert block 210.

[0033] When it is necessary to disassemble the outer casing, the user can pull the pull ring 221 to cause the corresponding traction rope 222 to pull the corresponding insert 210 to separate from the side plate 110, thus completing the quick disassembly of the outer casing.

[0034] like Figure 4 As shown, one corner of the insert 210 is chamfered.

[0035] After maintenance is completed, the user can move the corresponding side plate 110 back to its original position and then press the top cover 220 directly onto the side plate 110. During the pressing process, the chamfered part contacts the side edge of the side plate 110, and then the insert 210 is compressed and shrinks, causing the top cover 220 to move quickly to the corresponding position and complete the quick docking with the side plate 110.

[0036] like Figure 4 As shown, two springs 211 are provided on the outer side of the insert block 210, and one end of the spring 211 is installed inside the top cover 220.

[0037] With the spring 211, after the insert 210 abuts against the side of the side plate 110, the spring 211 is in a compressed state. When the insert 210 moves to the corresponding insertion position, the spring 211 deforms and resets, driving the insert 210 to dock with the corresponding side plate 110. The spring 211 applies pressure to the insert 210 in real time, which can reduce the possibility of accidental separation between the insert 210 and the side plate 110.

[0038] like Figure 3 As shown, four strip grooves are provided on one side of the top cover 220, and the strip grooves are adapted to the shape of the side plate 110.

[0039] The strip groove is used to connect with the side plate 110 to ensure stability after installation.

[0040] like Figure 3 As shown, a set of wire harness slots is provided on the other side of the top cover 220.

[0041] The use of a wire harness slot facilitates the connection of the display cable on the top cover 220 to the sensor body 100.

[0042] It should be noted that when the top cover 220 is removed, the cable between the display screen and the sensor body 100 is connected. Sufficient length of this cable can be reserved during installation so that the user can place it outside the removal area after the top cover 220 is removed.

[0043] Working principle: When maintenance is required, the user pulls the pull ring 221, causing the traction rope 222 to drive the corresponding insertion block 210 to separate from the corresponding side plate 110. Then, the top cover 220 is removed and placed aside. Next, the sensor body 100 is slid along the docking block, and then the four side plates 110 are laid flat in sequence so that the outside of the sensor body 100 is unobstructed. After the maintenance is completed, the corresponding side plates 110 are reset in sequence, and then the sensor body 100 is pushed back to its original position. Then, the top cover 220 is pressed down along the top of the four side plates 110 until the insertion block 210 is inserted into the corresponding side plate 110, completing the installation after the maintenance.

[0044] It should be noted that the sensor body 100 mentioned above is a temperature and humidity sensor. This type of sensor is a relatively mature device with existing technology. The specific model can be selected according to actual needs. At the same time, the sensor body 100 can be powered by an internal power supply or by AC power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0045] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0046] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
