[0026] The technical solution of the utility model is described below in conjunction with the accompanying drawings and embodiments.

[0027] like Figures 1 to 5 As shown, the utility model discloses a fully enclosed protective shell for a thermostat, comprising a shell 1, wherein the shell 1 is provided with a housing cavity for accommodating the thermostat, the first end of the shell 1 is provided with an opening 11, the second end of the shell 1 is provided with a sealing plate 12, and the sealing plate 12 is provided with a positioning and protection mechanism 9; a cover body 2, wherein the cover body 2 is connected to the opening 11 of the shell 1 by a snap assembly; and a cable 8, wherein the cable 8 passes through the positioning and protection mechanism 9 and is electrically connected to the thermostat, and the positioning and protection mechanism 9 and the cable 8 are correspondingly arranged. In this way, the cover body 2 and the shell body 1 are connected by a snap-fit ​​assembly, which makes loading and unloading more convenient and more efficient, and effectively solves the problem of inconvenient loading and unloading caused by screw fixing connection in the prior art; by providing a positioning protection mechanism 9 on the sealing plate 12, the positioning protection mechanism 9 can facilitate the cable 8 to pass through and be electrically connected to the temperature controller on the one hand, and can position and protect the cable 8 after the electrical connection on the other hand, effectively solving the problem that most of the cables 8 in the prior art are exposed, and due to the influence of external factors such as external force and friction, the cable 8 is easy to shake and fall off, and the surface of the cable 8 is damaged by wear.

[0028] It should be noted that the first end of the shell 1 is provided with an opening 11, and the second end of the shell 1 is provided with a sealing plate 12. After the cover 2 is connected to the opening 11 of the shell 1, the thermostat can be fully surrounded and protected, which has a better protection effect on the thermostat.

[0029] In this embodiment, the buckle assembly includes an insert plate 4 fixed on the cover body 2 and a clamping plate 6 movably arranged on the housing 1, and the clamping plate 6 is connected with the insert plate 4. In this way, the cover body 2 and the housing 1 are connected with each other by the clamping connection between the insert plate 4 and the clamping plate 6.

[0030] In this embodiment, the plug board 4 is provided with a slot 5; the inner wall of the opening 11 of the housing 1 is provided with a receiving slot 13, the plug board 6 is movably arranged in the receiving slot 13, a spring 7 is fixed between the first end of the plug board 6 and the receiving slot 13, and a locking portion 61 is provided at the second end of the plug board 6, and the locking portion 61 extends out of the receiving slot 13 and is connected to the locking slot 5. In this way, the locking portion 61 on the plug board 6 extends out of the receiving slot 13 and is connected to the locking slot 5 on the plug board 4, so that the cover body 2 and the housing 1 are connected in a locking manner; it should be noted that in the initial state, the elastic force of the spring 7 causes the locking portion 61 at the second end of the plug board 6 to extend out of the receiving slot 13, when the plug board 4 is inserted relative to the plug board 6, the plug board 4 pushes the plug board 6 to move up, compressing the spring 7, and when the locking portion 61 of the plug board 6 corresponds to the slot 5, the spring 7 is released, pushing the locking portion 61 at the second end of the plug board 6 to be locked in the slot 5.

[0031] In this embodiment, an inclined surface 41 is provided on the end of the plug board 4 and is arranged corresponding to the locking portion 61. In this way, when the plug board 4 moves relative to the locking portion 61 of the clamping plate 6, the locking portion 61 moves along the inclined surface 41 under the action of the inclined surface 41; more specifically, the inclined surface 41 presses the locking portion 61 of the clamping plate 6 to move upward, thereby compressing the spring 7.

[0032] In this embodiment, the clamping slot 5 is an arc-shaped slot, and the clamping portion 61 is an arc-shaped portion. In this configuration, the clamping portion 61 is an arc-shaped portion, so that when the clamping portion 61 and the inclined surface 41 of the plug board 4 act with thrust, they will not get stuck, so that the clamping portion 61 moves along the inclined surface 41; the clamping slot 5 is an arc-shaped slot, and when the clamping portion 61 is located in the clamping slot 5, under the action of pulling force, the arc-shaped clamping portion 61 can be easily disengaged from the arc-shaped clamping slot 5, thereby achieving the purpose of convenient loading and unloading.

[0033] In this embodiment, the positioning protection mechanism 9 includes a mounting tube 91, a threaded tube 1 92, a threaded rod 93, a threaded tube 2 94 and a clamping plate 95. The mounting tube 91 is fixed on the sealing plate 12 of the housing 1. A through hole 99 is provided in the mounting tube 91 for the cable 8 to pass through. The threaded tube 1 92 is fixed on the outer wall of the mounting tube 91. The first end of the threaded rod 93 is threadedly connected with the threaded tube 1 92. The second end of the threaded rod 93 extends into the through hole 99 and is threadedly connected with the threaded tube 2 94. The threaded tube 2 94 is fixedly connected with the clamping plate 95. The clamping plate 95 is arranged corresponding to the cable 8. In this arrangement, when the cable 8 is assembled, the terminal at the end of the cable 8 is passed through the through hole 99 and connected to the temperature controller circuit. Then the threaded rod 93 is rotated to drive the threaded tube 2 94 to move downward. The threaded tube 2 94 drives the clamping plate 95 to clamp the cable 8. When disassembling, the threaded rod 93 is rotated in the opposite direction to drive the threaded tube 2 94 to move downward. The threaded tube 2 94 drives the clamping plate 95 to loosen the cable 8.

[0034] In this embodiment, the clamping plate 95 is an arc-shaped plate, and a plurality of convex strips 97 for clamping the cable 8 are provided on the inner wall of the clamping plate 95. In this way, the clamping plate 95 can clamp the cable 8 better through the plurality of convex strips 97, thereby preventing the cable 8 from shaking and falling off, and preventing the surface of the cable 8 from being worn and damaged.

[0035] In this embodiment, a guide rod 96 is fixed on the clamping plate 95, and a guide hole 98 is provided on the mounting tube 91. The guide rod 96 is inserted into the guide hole 98 and is slidably connected with the guide hole 98. In this way, when the clamping plate 95 moves, it is lifted and lowered in a straight line, which prevents the clamping plate 95 from swinging and displacing, resulting in poor clamping effect of the cable 8. More specifically, the guide rod 96 is arranged parallel to the threaded rod 93 and spaced apart.

[0036] In this embodiment, the housing 1 is provided with a plurality of heat dissipation slots 3 corresponding to the thermostat. This arrangement has a better heat dissipation effect, thereby increasing the service life of the thermostat. More specifically, the heat dissipation slots 3 are arranged on the side wall of the housing 1, which reasonably utilizes the design space of the housing 1.

[0037] In this embodiment, a panel 21 corresponding to the thermostat is provided on the cover 2. This arrangement makes it easy to set the preset temperature of the thermostat and to intuitively understand the real-time temperature of the device. Compared with the external panel 21 in the prior art, the design space of the cover 2 is reasonably utilized.

[0038] Working principle of this utility model:

[0039] S1. The cover body 2 is pushed to contact the shell 1 so that the plug board 4 on the cover body 2 is inserted into the opening 11 of the shell 1. In this process, the card plate 6 on the shell 1 moves under the extrusion of the inclined surface 41 of the plug board 4 to compress the spring 7 to deform, and finally the card plate 6 contacts the surface of the plug board 4. Under the action of the force, the card plate 6 slides along the surface of the plug board 4. When the card portion 61 of the card plate 6 corresponds to the card slot 5 of the plug board 4, the spring 7 is released and the deformation is restored to push the card portion 61 of the card plate 6 to insert into the card slot 5, limit the plug board 4, and thus facilitate quick loading and unloading between the cover body 2 and the shell 1.

[0040] S2. Push the cable 8 through the through hole 99 of the mounting tube 91 and electrically connect it to the temperature controller. Rotate the threaded rod 93. Under the threaded connection, the threaded tube 94 can be pushed to move, so as to drive the clamping plate 95 to move. At the same time, the guide rod 96 can be driven to slide along the guide hole 98 of the mounting tube 91 to guide the clamping plate 95 to ensure the stable movement of the clamping plate 95. Finally, the clamping plate 95 drives the convex strip 97 to contact the cable 8 and clamp the cable 8 to prevent the cable 8 from shaking and falling off and the surface of the cable 8 from being worn and damaged.

[0041] The embodiments of the present invention are described above in conjunction with the accompanying drawings, but the present invention is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the enlightenment of the present invention, ordinary technicians in this field can also make many forms without departing from the scope of protection of the present invention and the claims, all of which belong to the protection scope of the present invention.
