Description

Technical Field

[0001] The utility model belongs to the technical field of thermostat installation, and in particular relates to a thermostat panel component. Background Art

[0002] A thermostat refers to a series of automatic control components that produce certain special effects and conduction or disconnection actions by physically deforming the switch inside according to the temperature changes in the working environment. It is also called a temperature control switch, temperature protector, temperature controller, or simply a thermostat. Its working principle is to automatically sample and timely monitor the ambient temperature through a temperature sensor. When the ambient temperature is higher than the control set value, the control circuit is started, and the control hysteresis can be set. If the temperature is still rising, when it rises to the set over-limit alarm temperature point, the over-limit alarm function is activated. When the controlled temperature cannot be effectively controlled, in order to prevent damage to the equipment, the tripping function can be used to stop the equipment from continuing to run.

[0003] When installing most of the existing thermostats, it is usually necessary to reserve an installation groove on the wall, then put the junction box into the installation groove, and then connect the box plate to the wall to fix the junction box in the wall. After the middle frame is installed outside the box plate, the display component is connected to the box plate by snapping. Since the middle frame is not a standard part, different middle frames have different thicknesses, and the existing snap-in method cannot adapt to middle frames of different thicknesses, resulting in a large gap between the display component and the middle frame, which not only affects the appearance, but also causes a large amount of dust to enter the thermostat, affecting the use of the thermostat.

DETAILED DESCRIPTION

[0032] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0033] like Figures 1 to 5As shown, a thermostat panel assembly includes a display screen 1, a screen frame 2, a back plate 3, a middle frame 4, a junction box 5, a box plate 6 and a wiring terminal 7. The display screen 1 is connected to the surface of the screen frame 2, the screen frame 2 and the back plate 3 are detachably connected, the wiring terminal 7 is placed in the junction box 5, the junction box 5 is arranged in the wall, the junction box 5 is arranged on the back of the box plate 6, the middle frame 4 is sleeved on the outside of the box plate 6, the surface of the back plate 3 is protruded with a middle convex portion 31, and the two side surfaces corresponding to the middle convex portion 31 are protruded with a plurality of protrusions 1 arranged in a linear array, and the plurality of protrusions 1 on each side form a matching block 8, and the surface of the box plate 6 is connected with a buckle 9, the buckle 9 includes a connecting portion 91 and a clamping portion 92, and the surface of the connecting portion 91 is protruded with a plurality of protrusions 2 corresponding to the protrusions 1 to form a clamping portion 92, and the matching block 8 and the buckle 9 cooperate with each other to connect the box plate 6 and the back plate 3.

[0034] Specifically, a positioning groove is provided on the surface of the back plate 3, and a positioning plate is connected to the surface of the box plate 6. The connection position of the back plate 3 and the box plate 6 is fixed by the cooperation between the positioning groove and the positioning plate.

[0035] It should be noted that both the protrusion 1 and the protrusion 2 are trapezoidal bodies. When the back panel 3 is pushed toward the box panel 6 so that the two are snapped together, the contact surfaces of the protrusion 1 and the protrusion 2 are non-parallel surfaces with a larger inclination (i.e., relatively gentle). The inclined surface with a larger inclination angle is more convenient for connecting the two. The non-parallel surface on the other side has a smaller inclination, which is close to vertical, preventing the back panel 3 from easily falling off the box panel 6. When the back panel 3 needs to be removed from the box panel 6, it needs to be pulled with a little force.

[0036] It should be further explained that the buckle 9 is similar to a step shape. The buckle 9 of this shape cooperates with the matching block 8 so that the insertion depth of the display component is different to cooperate with the installation of other components.

[0037] Furthermore, the box plate 6 includes a flat plate portion 61 , a cover portion 62 corresponding to the edge of the junction box 5 protrudes from the side of the flat plate portion 61 away from the display screen 1 , and the buckle 9 is connected to the side of the flat plate portion 61 away from the cover portion 62 .

[0038] Furthermore, at least two groups of matching blocks 8 are provided, the middle convex portion 31 is “H”-shaped, and the two groups of matching blocks 8 are respectively provided at the inner bottom of the upper half and the inner top of the lower half of the “H”-shaped middle convex portion 31 .

[0039] like Figure 4 , Figure 6 and Figure 7 In the partial structure shown, the screen frame 2 and the back plate 3 are detachably connected by screws 10.

[0040] Furthermore, the screw 10 is used to connect one side of the screen frame 2 and the back plate 3 , and a snap-in assembly is provided on the surface of the screen frame 2 for snap-in connection with the other side of the screen frame 2 and the back plate 3 away from the screw 10 .

[0041] Furthermore, the snap-on assembly includes a front stopper 21 protruding from the edge of the screen frame 2 near the back panel 3, the inner wall of the screen frame 2 is connected to a rear stopper 23, a certain space is reserved between the rear stopper 23 and the front stopper 21, and a groove 22 matching with the front stopper 21 is provided on the surface of the back panel 3 on one side away from the display screen 1, and the groove 22 is snapped between the rear stopper 23 and the front stopper 21.

[0042] Specifically, two groups of screws 10 and snap-in components are provided, and are all arranged at the four corners of the back panel 3. Through the coordinated arrangement of the screws 10 and the snap-in components, the connection is stabilized while also speeding up the connection between the screen frame 2 and the back panel 3.

[0043] It should be noted that when connecting the back panel 3 to the box plate 6, the screen frame 2 and the back panel 3 need to be installed first. In actual use, the side of the back panel 3 with the groove 22 is inclined toward the screen frame 2, and the groove 22 is snapped between the rear block 23 and the front block 21. Then, the screen frame 2 and the back panel 3 are connected with the screws 10 on the side away from the snap-on part.

[0044] like Figure 7 and Figure 8 In the partial structure shown, the junction box 5 and the box plate 6 are connected by snap-fitting.

[0045] Furthermore, the box opening of the junction box 5 is rectangular, and the two adjacent corners of the junction box 5 are inclined surfaces. The inclined surfaces on both sides of the inner wall of the junction box 5 and a group of planes not adjacent to the two groups of inclined surfaces are connected with a clamping block 11, and a clamping piece is connected to the position corresponding to the clamping block 11 at the edge of the box cover portion 62, and the clamping piece cooperates with the clamping block 11 to connect the junction box 5 and the box plate 6.

[0046] Furthermore, the clamping part includes a clamping block 12 and two groups of clamping rings 13. The clamping block 12 and the clamping ring 13 both include a plate connecting portion. The plate connecting portion of the clamping block 12 is protruded with a protruding block, which is matched and connected with the clamping block 11 on the plane. The plate connecting portions of the two groups of clamping rings 13 are both provided with a clamping groove 131, and the two groups of clamping grooves 131 respectively cooperate with the two groups of clamping blocks 11 on the inclined surfaces.

[0047] Furthermore, the size and shape of the internal space of the junction box 5 are consistent with the size and shape of the wiring terminal 7. The wiring terminal 7 is plugged into the interior of the junction box 5. The surface of the junction box 5 is provided with wiring holes corresponding to the wiring ports on the wiring terminal 7.

[0048] It should be noted that the size and shape of the internal space of the junction box 5 are consistent with the size and shape of the terminal 7, so the terminal 7 can be directly placed in the junction box 5. The box plate 6 cooperates with the junction box 5 to fix the terminal 7 in the junction box 5 and cannot be moved.

[0049] Example 2

[0050] The present embodiment provides a thermostat panel assembly. On the basis of the first embodiment, further improvements are made by changing the shapes of the snap-on portion 92 of the buckle 9 and the mating block 8 so that the two cooperate with each other, so that the connection between the back plate 3 and the box plate 6 can be tighter, and the back plate 3 and the box plate 6 cannot be separated by pulling. The two sides of the middle frame 4 are set to be movable, and a pushing assembly 14 is added so that the buckle 9 can be pushed out from the side of the mating block 8, thereby releasing the connection between the buckle 9 and the mating block 8.

[0051] Specifically, Figures 10 to 14 In the partial structure shown, four groups of matching blocks 8 are provided, and two groups of matching blocks 8 located on the same side form a pair. The two pairs of matching blocks 8 are symmetrically arranged, and a gap is left between the two groups of matching blocks 8 in each pair of matching blocks 8. The surface of the second protrusion is a smooth arc surface, and its cross-section is slope-shaped. The position where the side of the second protrusion close to the junction box 5 is connected to the connecting part 91 is recessed toward the direction of the display screen 1, and the first protrusion is inserted between the two groups of protrusions 2 and is consistent with the shape of the space formed between the two groups of protrusions 2.

[0052] It should be noted that this shape setting can prevent the back plate 3 from being easily removed from the box plate 6, thereby strengthening the connection between the two.

[0053] Furthermore, the middle frame 4 includes a fixed portion and two groups of corresponding side walls 15 slidably connected to the inner wall of the fixed portion. The inner surface of the side wall 15 is connected to a pushing component 14. Pressing the side walls 15 on both sides of the middle frame 4 drives the pushing component 14 to push a pair of buckles 9 between a pair of mating blocks 8.

[0054] It should be noted that, when the buckle 9 is pushed to move between a pair of matching blocks 8 , the screen frame 2 can be held and moved away from the box plate 6 , so that the back plate 3 can be removed from the box plate 6 .

[0055] Furthermore, the pushing assembly 14 corresponds to the buckle 9 one by one, and the pushing assembly 14 includes a connecting rod 141, a spring 142, a spring 2 143 and a connecting block 144. One end of each two groups of connecting rods 141 is connected to the inner surface of a group of side walls 15, and the other end of the connecting rod 141 is fixedly connected to the connecting portion 91 of the buckle 9. The buckle 9 is slidably connected to the surface of the flat plate portion 61, and the connecting block 144 is fixedly connected to the surface of the flat plate portion 61. The two ends of the spring 2 143 are respectively fixedly connected to the surface of the connecting portion 91 of the buckle 9 and the surface of the connecting block 144. The inner surface of the side wall 15 is fixedly connected with a spring 142, and one end of the spring 142 is connected to the inner wall of the fixed portion of the middle frame 4.

[0056] It should be noted that spring 1 142 and spring 2 143 play a resetting role.

[0057] It should be further explained that when bump one and bump two are of the shape in Example 1, the middle frame 4 can also be set to this form and cooperate with the pushing component 14 to move the buckle 9 out from the side of the matching block 8, so as to remove the back panel 3. Compared with the direct pulling method, this disassembly method reduces the probability of damage to the buckle 9.

[0058] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
