Description

Technical Field

[0001] This utility model relates to the field of thermostat technology, and in particular to a thermostat and its cover. Background Technology

[0002] A thermostat senses the ambient temperature and controls the heating or cooling function of the equipment according to a preset temperature range to maintain a stable ambient temperature. The thermostat's cover protects the internal electronic components and circuitry from adverse external factors, ensuring the thermostat's stability and reliability. Simultaneously, the cover acts as a seal, preventing unnecessary interaction between the internal circuitry and the external environment, further improving the thermostat's safety and performance. For example, a Chinese patent discloses a thermostat and its cover (application number CN201320064013.6). The notch in this thermostat and its cover increases the electrical clearance and creepage distance, thus improving the thermostat's electrical performance. However, the interior of the cover cannot be adjusted accordingly, therefore it cannot adapt to the installation and use requirements of thermostats of different specifications, reducing the thermostat's versatility and adaptability. Utility Model Content

[0003] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to provide a thermostat and its cover. When the shaft rotates, the first bevel gear will drive the second bevel gear to rotate, which in turn drives the bidirectional screw so that the two positioning blocks can move in opposite directions, thereby realizing the positioning and adjustment function inside the cover, which facilitates the quick fixing of the thermostat. In addition, the spring set in the inner wall can absorb the impact force from the outside and protect the inside of the cover.

[0004] To achieve the above objectives, the following structure is proposed:

[0005] Structure 1: This utility model also provides a cover with the above-mentioned features, comprising: a cover body, wherein two symmetrically arranged upright plates are fixedly connected inside the cover body, and a bidirectional screw is rotatably connected inside each of the two upright plates. A positioning block is threaded onto the outside of each bidirectional screw. A shaft is rotatably connected inside the cover body, and a first bevel gear is fixedly connected to both ends of the shaft. A second bevel gear is meshed with the outside of the first bevel gear, and the side surface of the second bevel gear is fixedly connected to the bidirectional screw. When the shaft rotates, the first bevel gear drives the second bevel gear to rotate, which in turn drives the bidirectional screw, allowing the two positioning blocks to move in opposite directions. This achieves the positioning and adjustment function inside the cover body, facilitating quick fixation of the thermostat.

[0006] According to the cover of this utility model, each of the two upright plates has a groove inside, and the two upright plates are slidably connected to the positioning block through the grooves. The upright plates provide sliding support for the positioning block and prevent the positioning block from shifting laterally when moving.

[0007] According to the present invention, a cover has two symmetrically distributed inserts on its exterior, and a spring is provided between the cover and the upright plate. The spring can absorb and disperse external impact forces or vibrations, thereby protecting the cover and its internal components from damage.

[0008] According to the present invention, a cover is provided with heat dissipation holes on both sides of the cover body, and an electromagnetic shielding layer is provided on the inner wall of the cover body. Through the heat dissipation holes, the heat inside the cover body can be effectively dissipated to the external environment, thereby maintaining the normal operating temperature of the equipment. The electromagnetic shielding layer can prevent external electromagnetic interference from affecting the electronic components inside the cover body.

[0009] According to the present invention, a cover is provided on the outside of the cover body, and a protective glass is fixedly installed inside the temperature display part. The protective glass provides a clear and intuitive viewing window, allowing users to easily check the temperature information at any time.

[0010] According to the present invention, an adjusting handle is fixedly connected to the outside of the shaft, and an anti-slip part is provided on the outside of the adjusting handle. The rotation direction of the shaft can be adjusted accordingly by adjusting the adjusting handle, and the anti-slip part enhances the grip stability and safety.

[0011] Structure Two: This utility model also provides a temperature controller as described above, with a housing. The housing has a cover as shown in Structure One on its exterior. Inside the housing, a controller, operational amplifier, heater, cooler, and temperature sensor are fixedly installed. The controller is electrically connected to the operational amplifier, and the operational amplifier is electrically connected to the temperature sensor. The controller is also electrically connected to the heater and cooler, which are fixedly installed on the lower bottom wall of the housing. The temperature sensor detects the temperature inside or outside the housing and converts the temperature information into an electrical signal. The detected temperature signal is transmitted to the operational amplifier for amplification. After amplification, the operational amplifier transmits the amplified signal to the controller for regulation. When the temperature is higher than a preset range, the controller controls the cooler to turn on; when the temperature is lower than the preset range, the controller controls the heater to turn on, thereby achieving precise control of the external temperature.

[0012] According to the present invention, a temperature controller has a groove fixedly connected to the upper surface of the housing, and the outside of the groove is engaged with the insert block of the cover during use.

[0013] Beneficial effects: Compared with the prior art, this new type of thermostat and its cover, when the shaft rotates, the first bevel gear drives the second bevel gear to rotate, which in turn drives the bidirectional screw so that the two positioning blocks can move in opposite directions, thereby realizing the positioning and adjustment function inside the cover, which facilitates the quick fixation of the thermostat. In addition, the spring set in the inner wall can absorb the impact force from the outside and protect the inside of the cover. Attached Figure Description

The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0023] Reference Figure 1-3As a first embodiment, this utility model provides a cover, which includes: a cover body 1, two symmetrically arranged upright plates 2 are fixedly connected inside the cover body 1, a bidirectional screw 3 is rotatably connected inside each of the two upright plates 2, a positioning block 4 is threadedly connected to the outside of the bidirectional screw 3, a groove 8 is provided inside each of the two upright plates 2, and the two upright plates 2 are slidably connected to the positioning block 4 through the groove 8, a shaft 5 is rotatably connected inside the cover body 1, an adjusting handle 15 is fixedly connected to the outside of the shaft 5, an anti-slip part is provided on the outside of the adjusting handle 15, a first bevel gear 6 is fixedly connected to both ends of the shaft 5, a second bevel gear 7 is meshed with the outside of the first bevel gear 6, and the side surface of the second bevel gear 7 is fixedly connected to the bidirectional screw 3;

[0024] Specifically, rotating the adjustment handle 15 causes the shaft 5 to drive the first bevel gears 6 at both ends to rotate. Through the meshing connection between the first bevel gear 6 and the second bevel gear 7, the bidirectional screw 3 rotates, thereby driving the two positioning blocks 4 to move. Since the bidirectional screw 3 has opposite threads on its exterior, the two positioning blocks 4 can move towards each other.

[0025] The cover 1 has two symmetrically distributed inserts 9 on its exterior. A spring 10 is provided between the cover 1 and the upright plate 2. Heat dissipation holes 11 are provided on both sides of the cover 1. An electromagnetic shielding layer 12 is provided on the inner wall of the cover 1. A temperature display unit 13 is provided on the exterior of the cover 1. A protective glass 14 is fixedly installed inside the temperature display unit 13.

[0026] Specifically, the spring 10 can absorb and disperse external impacts or vibrations, thereby protecting the internal components of the cover 1. The heat dissipation holes 11 can dissipate heat from inside the cover 1. In addition, the protective glass 14 allows users to easily check the temperature information at any time.

[0027] Reference Figure 4-5 As a second embodiment, this utility model provides a temperature controller, which includes a housing 16. The housing 16 is provided with a cover as shown in the first embodiment. The housing 16 is fixedly installed with a controller 17, an operational amplifier 18, a heater 19, a cooler 20 and a temperature sensor 21. The controller 17 is electrically connected to the operational amplifier 18, the operational amplifier 18 is electrically connected to the temperature sensor 21, the controller 17 is electrically connected to the heater 19 and the cooler 20, the heater 19 and the cooler 20 are fixedly installed on the lower bottom wall of the housing 16, and a groove 22 is fixedly connected to the upper surface of the housing 16. The outside of the groove 22 is engaged with the insert block 9 of the cover 1 during use.

[0028] Specifically, the temperature sensor 21 transmits the detected temperature signal to the operational amplifier 18 for amplification. The operational amplifier 18 then transmits the amplified signal to the controller 17 for regulation. When the temperature is higher than the preset range, the controller 17 controls the cooler 20 to turn on. When the temperature is lower than the preset range, the controller 17 controls the heater 19 to turn on, thereby achieving precise control of the external temperature.

[0029] Working principle: First, the insert 9 of the cover 1 is aligned with the groove 22 on the outside of the housing 16. Then, the adjustment handle 15 is rotated so that the shaft 5 drives the first bevel gear 6 at both ends to rotate. The first bevel gear 6 drives the second bevel gear 7 to rotate the bidirectional screw 3. The bidirectional screw 3 on both sides drives the two positioning blocks 4 to move. Since the bidirectional screw 3 has opposite threads on the outside, the two positioning blocks 4 can move towards each other, thereby fixing the housing 16 of the thermostat.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
