Description

Technical Field

[0001] The utility model relates to the technical field of temperature control valve control, and specifically relates to a temperature control valve controller. Background Art

[0002] The temperature control valve is an important device in the air conditioning system, and its function is to control the temperature of the indoor air to ensure comfort. In the vehicle air conditioning system, the temperature control valve can adjust the temperature at the outlet of the condenser and cool the air blown out by the condenser to a specified temperature. In the air conditioning systems of homes and workplaces, the temperature control valve can control the concentration of the refrigeration or heating medium in the condenser or evaporator, thereby adjusting the air temperature.

[0003] Among them, the temperature control valve mainly consists of a temperature sensor, an electric actuator, and a controller. When the indoor temperature is lower than the preset temperature, the controller will send a corresponding signal to make the electric actuator open the valve, allowing the refrigeration or heating medium to flow through the cooler or evaporator, and blowing cold air or hot air into the room to increase the indoor temperature. When the indoor temperature is higher than the preset temperature, the controller will send a corresponding signal to make the electric actuator close the valve and stop refrigeration or heating.

[0004] Currently, the controller used for the temperature control valve of the temperature controller is in a box structure. A toggle switch is provided on the box body, and a micro switch is provided inside. An externally threaded connecting post is provided on the toggle switch. When installing the controller, the connecting post is inserted into the positioning hole of the installation part, and then a nut and thread are used for fastening connection so that the controller is firmly installed. However, since the air conditioning system (such as a chassis) will generate vibrations during operation, the long-term vibrations are likely to cause the nut and thread connection to loosen, and then cause the controller to loosen and vibrate greatly. The vibrating controller is not only likely to damage the micro switch inside it, but also affects the reliability of the connection between the wires on the controller and the electric actuator.

[0005] Therefore, the utility model provides a temperature control valve controller. Content of the Utility Model

[0006] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a temperature control valve controller to solve the problems raised in the above background art. The utility model has the advantages that the connection between the positioning post and the connecting nut is reliably relaxed after being fastened, and the operation of screwing the connecting nut and the positioning post is more labor-saving, making the connection and disassembly operations between the controller and the installation part more convenient.

[0007] To achieve the above object, the present utility model is realized through the following technical solutions: A temperature control valve controller, including a controller body, an outer box is provided on the controller body, a toggle switch is provided on one side of the outer box and one end thereof is connected with a wire. The toggle switch includes a positioning post connected to the outer box and a toggle rod located at one end of the positioning post. A connecting thread is provided on the outer peripheral wall of the positioning post, and a connecting nut is screwed on the connecting thread. A plurality of circumferentially distributed long grooves are provided on the outer peripheral wall of the positioning post, and the long grooves are parallel to the axis of the positioning post. An arched elastic sheet is provided in the long groove, and the arch top of the arched elastic sheet protrudes out of the mouth of the long groove.

[0008] Further, clamping grooves are provided at both ends in the long groove, and both ends of the arched elastic sheet are respectively clamped and matched with the adjacent clamping grooves.

[0009] Further, a rod body with a circular cross-section is fixedly provided in the middle of the arched elastic sheet, and the rod body is located outside the long groove.

[0010] Further, the number of the long grooves is three.

[0011] Further, the connecting nut is a wing nut.

[0012] Further, a rubber pad is bonded to the side of the outer box where the positioning post is located.

[0013] Further, uniformly distributed protrusions are fixedly provided on the outer side of the rubber pad.

[0014] The beneficial effects of the present utility model are as follows:

[0015] 1. In the present utility model, by providing long grooves on the outer peripheral wall of the positioning post, and then providing an arched elastic sheet protruding outward in the long grooves, the positioning post is passed through the mounting hole and connected with the connecting nut. During the process of tightening the connecting nut, the connecting nut will squeeze and cross over the arched elastic sheet, and the arched elastic sheet presents an elastic undulating change. Due to the elastic squeezing effect of the arched elastic sheet, the connecting nut will not loosen, thereby effectively avoiding the loosening of the entire installed controller and extending the service life of the controller.

[0016] 2. In the present utility model, by providing a column body with a circular cross-section in the middle of the arched elastic sheet, when the connecting nut passes through the column body, due to the arc surface structure of the column body, the screwing resistance of the connecting nut is reduced, and this kind of functional cylindrical surface structure will not damage the internal thread of the connecting nut. This kind of setting greatly reduces the resistance of the connection and separation operations between the connecting nut and the positioning post, and improves the convenience of the installation and disassembly of the connecting nut.

[0021] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation manners.

[0022] Please refer to Figures 1 to 3 , the present utility model provides a technical solution: a temperature control valve controller, including a controller body 1, an outer box 11 is arranged on the controller body 1, the outer box 11 is of a square structure, a toggle switch 12 is arranged on one side of the outer box 11 and one end thereof is connected with a wire 13, one end of the wire 13 located inside the outer box 11 is connected with a micro switch, and the other end of the wire 13 is provided with an electrical plug.

[0023] Among them, the toggle switch 12 is a manually operated switch, the toggle switch 12 includes a positioning pile 121 connected to the outer box 11 and a toggle rod 122 located at one end of the positioning pile 121. The toggle switch 12 can be controlled to be switched on and off by swinging the toggle rod 122 back and forth. A connection thread 1212 is provided on the outer peripheral wall of the positioning pile 121, and a connection nut 14 is screwed on the connection thread 1212. During use, the positioning pile 121 is passed through the mounting hole of the external mounting plate, and then the connection nut 14 is screwed on the positioning pile 121. When the connection nut 14 and the outer box 11 clamp the mounting plate, the controller body 1 is firmly installed. In order to overcome the problem of loosening of the connection nut 14 caused by external vibration, the present application now improves the positioning pile 121.

[0024] Specifically, a plurality of circumferentially distributed long grooves 1211 are formed in the outer peripheral wall of the positioning pile 121. The long grooves 1211 are parallel to the axis of the positioning pile 121. An arched elastic piece 2 is arranged in the long groove 1211. The arched elastic piece 2 is made of spring steel. The arch top of the arched elastic piece 2 protrudes out of the opening of the long groove 1211. When the connecting nut 14 rotates on the positioning pile 121, it will squeeze the arched elastic piece 2, and the arched elastic piece 2 is pressed into the long groove 1211. When the connecting nut 14 is in close contact with one side of the external mounting plate, the arched elastic piece 2 protrudes out of the opening of the long groove 1211 again. At the same time, the arched elastic piece 2 will elastically squeeze the connecting nut 14 towards the mounting plate, thereby effectively preventing the problem of loosening of the connecting nut 14 from occurring.

[0025] Further, clamping grooves 12111 are formed at both ends in the long groove 1211. Both ends of the arched elastic piece 2 are respectively clamped and matched with the adjacent clamping grooves 12111. The purpose of this setting is to facilitate the docking and separation of the arched elastic piece 2 and the long groove 1211, reduce the manufacturing difficulty. During installation, the arched elastic piece 2 is bent, and then its two ends are extended into the long groove 1211. After releasing the arched elastic piece 2, its two ends will be inserted into the corresponding clamping grooves 12111.

[0026] In this embodiment, a rod body 21 with a circular cross-section is fixedly arranged in the middle of the arched elastic piece 2. The rod body 21 is located outside the long groove 1211, that is to say, the rod body 21 is located at the arch top position of the arched elastic piece 2. During the initial screwing movement of the connecting nut 14 and the positioning pile 121, it will first contact the rod body 21, and the whole arched elastic piece 2 is deformed by squeezing through the rod body 21. When the connecting nut 14 passes over the rod body 21 and then presses against one side of the mounting plate, the rod body 21 elastically presses against the opening of the connecting nut 14. The setting of the rod body 21 can reduce the frictional resistance between the internal thread of the connecting nut 14 and the rod body 21, making the connection and disassembly of the connecting nut 14 and the positioning pile 121 more labor-saving and convenient.

[0027] Further, the number of the long grooves 1211 is three. The elastic limiting effect of the three arched elastic pieces 2 on the connecting nut 14 makes the connection between the controller body 1 and the mounting plate more reliable.

[0028] Among them, the connecting nut 14 is a wing nut. The structure of the wing nut is convenient for hand-held installation and does not require a wrench.

[0029] In this embodiment, a rubber pad 3 is bonded to the side of the outer box 11 where the positioning pile 121 is located. Among them, uniformly distributed protrusions 31 are fixedly arranged on the outer side of the rubber pad 3. The functions of the rubber pad 3 and the protrusions 31 are to buffer the vibration transmitted from the mounting plate to the outer box 11 and play a role in shock absorption.

[0030] Working principle: When in use, when it is necessary to connect the controller body 1 and the mounting plate welded on the chassis, one end of the positioning pile 121 is passed through the positioning hole on the mounting plate, and then the connecting nut 14 and the connecting thread 1212 are manually screwed together and docked. When manually screwing the connecting nut 14, when the connecting nut 14 approaches the mounting plate, it will first contact the rod body 21. After the rod body 21 is squeezed, the arched elastic piece 2 deforms and moves into the long groove 1211. When the connecting nut 14 passes over the middle of the rod body 21 and abuts against the mounting plate, a part of the rod body 21 will be pressed against the mouth of the connecting nut 14 under the elastic extrusion of the entire arched elastic piece 2, so that the connecting nut 14 receives a squeezing force towards the mounting plate direction. Therefore, screwing the connecting nut 14 can be effectively prevented from loosening under the restriction of the arched elastic piece 2.

[0031] In addition, it should be understood that although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
