[0025] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0026] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0027] See also Figures 1 to 5 The embodiment of the utility model provides a temperature controller that is easy to disassemble. The temperature controller that is easy to disassemble includes: a mounting base 1, a housing 2, a front cover plate 3, an elastic pleated airbag 4 and a compressed air component 5.

[0028] In the embodiments of the present invention, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 5 The mounting base 1 is fixed with a housing 2, and the front end of the housing 2 is provided with a detachable front cover 3, specifically:

[0029] The outer walls of both side walls of the casing 2 are provided with side grooves 2a, and each of the side grooves 2a is provided with an elastic pleated airbag 4, the inner side wall of the elastic pleated airbag 4 is fixedly connected to the inner wall of the side groove 2a, and the two side walls of the casing 2 are provided with air storage chambers 2b, and the bottom of the air storage chamber 2b is communicated with the elastic pleated airbag 4 through a conduit, and the casing 2 is also provided with a gas compression component 5 for pressing the gas in the air storage chamber 2b into the elastic pleated airbag 4 and expanding the elastic pleated airbag 4 to clamp the front cover plate 3, and the inner walls of both side walls of the front cover plate 3 are provided with clamping grooves 3a for clamping the inflated elastic pleated airbag 4.

[0030] It should be noted that: after the housing 2 of the temperature controller is installed in the predetermined installation area through the installation base 1, the front cover 3 is covered on the housing 2. At this time, the elastic pleated airbag 4 is driven to expand by the compressed air component 5, and the expanded elastic pleated airbag 4 is inserted into the clamping groove 3a provided on the side wall of the front cover 3, so that the front cover 3 can be fixedly clamped. Since the expanded elastic pleated airbag 4 is an elastic structure, the impact force on the front cover 3 can be effectively alleviated when the front cover 3 is impacted, thereby greatly protecting the front cover 3.

[0031] When the front cover plate 3 needs to be removed to repair the components in the housing 2, the gas in the elastic pleated airbag 4 can be driven back to the air storage chamber 2b by the compressed air assembly 5, so that the elastic pleated airbag 4 shrinks and slides out of the clamping groove 3a provided on the side wall of the front cover plate 3, thereby facilitating the removal of the front cover plate 3 on the housing 2;

[0032] The two side walls of the housing 2 are provided with limiting slots 2d, and the inner side wall of the front cover 3 is fixedly engaged with limiting sliding ridges 31 that match the limiting slots 2d, so as to facilitate the front cover 3 to cover the housing 2.

[0033] In the embodiments of the present invention, please refer to Figure 3 and Figure 4 The compressed air assembly 5 is provided with two groups, and the two groups of compressed air assembly 5 are respectively arranged in two air storage chambers 2b opened in the casing 2. The compressed air assembly 5 includes a piston plate 51, and the piston plate 51 is slidably installed in the air storage chamber 2b opened in the casing 2, and a push rod 52 is fixedly installed on the upper surface of the piston plate 51. The push rod 52 extends out of the casing 2 through a threaded through hole 2c opened in the top of the air storage chamber 2b, and a threaded column 53 with a rotatable connection is installed on the extension of the push rod 52.

[0034] It should be noted that: the push rod 52 is pressed down so that the piston plate 51 discharges the gas in the gas storage chamber 2b into the elastic pleated airbag 4 to expand it, and when the threaded column 53 slides to the orifice of the threaded through hole 2c, the threaded column 53 is screwed into the threaded through hole 2c to complete the fixing of the push rod 52;

[0035] When the front cover 3 is removed, the threaded column 53 is reversely rotated so that the threaded column 53 is screwed out of the threaded through hole 2c and then the push rod 52 is pulled up. At this time, the piston plate 51 drives the gas storage chamber 2b to form a negative pressure, so that the gas in the elastic pleated airbag 4 flows back into the gas storage chamber 2b. Therefore, the elastic pleated airbag 4 contracts and slips out of the clamping groove 3a provided on the side wall of the front cover 3. Subsequently, the front cover 3 can be slid outward from the casing 2, so that it is convenient for the staff to effectively repair the components inside the temperature controller, which improves the convenience of the staff to repair the temperature controller.

[0036] An opening slot 3 b is provided at the tail of the upper end surface of the front cover plate 3 , and the opening slot 3 b can enable the front cover plate 3 to be inserted into the position of the push rod 52 .

[0037] The working principle of the temperature controller that is easy to disassemble provided by the utility model is as follows:

[0038] After the housing 2 of the temperature controller is installed to the predetermined installation area through the installation base 1, the front cover plate 3 is covered on the housing 2. At this time, the elastic pleated airbag 4 is driven to expand by the compressed air component 5. Specifically, the push rod 52 is pressed down so that the piston plate 51 discharges the gas in the air storage chamber 2b into the elastic pleated airbag 4 to expand it. When the threaded column 53 slides to the orifice of the threaded through hole 2c, the threaded column 53 is screwed into the threaded through hole 2c to complete the fixing of the push rod 52. The expanded and unfolded elastic pleated airbag 4 is inserted into the clamping groove 3a provided on the side wall of the front cover plate 3 to achieve the fixed clamping of the front cover plate 3. Since the expanded elastic pleated airbag 4 is an elastic structure, the impact force on the front cover plate 3 can be effectively alleviated when the front cover plate 3 is impacted, thereby greatly protecting the front cover plate 3.

[0039] When it is necessary to remove the front cover 3 to repair the components in the casing 2, it is only necessary to drive the gas in the elastic pleated airbag 4 to flow back into the air storage chamber 2b through the compressed air assembly 5. Specifically, reverse the threaded column 53 so that the threaded column 53 is screwed out of the threaded through hole 2c and then the push rod 52 is pulled up. At this time, the piston plate 51 drives the air storage chamber 2b to form a negative pressure, so that the gas in the elastic pleated airbag 4 flows back into the air storage chamber 2b. Therefore, the elastic pleated airbag 4 contracts and slips out of the snap-in groove 3a provided on the side wall of the front cover 3. Subsequently, the front cover 3 can be slid out from the casing 2, thereby facilitating the removal of the front cover 3 on the casing 2, facilitating the staff to effectively repair the components inside the temperature controller, and improving the convenience of the staff in repairing the temperature controller.

[0040] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.
