Description

Technical Field

[0001] This utility model relates to the field of solenoid valve technology, and in particular to a coil holder for a household solenoid valve. Background Technology

[0002] Currently, electromagnetic relays are widely used in household appliances. With the development of technology, their types are also increasing. The solenoid valve coil frame is an essential component of every electromagnetic relay. Existing household solenoid valves are formed by winding the solenoid valve coil frame with enameled wire and then assembling corresponding insert chips and other parts to form a winding assembly. The enameled wire needs to reach a qualified tightness during winding to ensure that the solenoid valve has a qualified performance. However, the existing solenoid valve coil frame cannot reflect the tightness of the winding in time when winding the enameled wire, and the yield rate of production cannot be guaranteed. Utility Model Content

[0003] In order to solve the problems mentioned in the background art, the present invention provides a household solenoid valve coil holder.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A household solenoid valve coil holder includes a winding body, an elastic external support assembly, and a locking mounting component. Enamelled wire is wound around the winding body. The winding body includes a winding drum and limiting rings disposed on the front and rear sides of the winding drum. The winding drum is symmetrically provided with several mounting grooves on its circumference. The mounting grooves extend from the front end of the winding drum to the middle of the winding drum and connect the inner and outer sides of the winding drum.

[0006] The elastic external support assembly includes an assembly box, an upper pusher and a lower pusher. The assembly box has an assembly channel that runs vertically through it. The upper pusher and the lower pusher are respectively installed in the assembly channel. At least one spring is connected between the lower pusher and the sliding block.

[0007] The locking mounting piece is installed at the front end of the elastic external support assembly after the assembly box is installed in the mounting slot, to prevent the elastic external support assembly from detaching from the mounting slot.

[0008] Preferably, limiting rings are provided on both the front and rear sides of the winding drum, so that the enameled wire can be wound around the winding drum and restricted by the limiting rings so that it cannot detach from the winding drum.

[0009] Preferably, the outer wall of the winding cylinder has an extension groove extending from the middle of the winding cylinder to the rear end of the winding cylinder. The extension groove is connected to the mounting groove and only extends to the outside of the winding cylinder without extending into the inside of the winding cylinder.

[0010] Preferably, the sliding block of the upper part is installed in the assembly channel, and the part of the sliding block that extends to the upper end of the assembly channel is equipped with an extension pusher. The extension pusher can be inserted into and fill the extension slot after the assembly box is placed into the mounting slot.

[0011] Preferably, the assembly box has an open window on the side opposite to the extension direction of the extension pusher, and an indicator piece that can extend out of the open window is installed at the bottom of the sliding block.

[0012] Preferably, the front and rear ends of the assembly box are symmetrically equipped with limit pins, the inner wall of the mounting groove is provided with a hole for the limit pins to be inserted, and the locking mounting part has a mating slot that allows the limit pins to be inserted.

[0013] Preferably, the locking mount has a through indicator window, the position and size of which correspond to the open window so that the indicator piece can extend into the indicator window.

[0014] Preferably, after the assembly box is fixedly installed in the mounting slot, when the indicator plate is close to the bottom of the open window, the upper surface of the extension pusher is flush with the outer peripheral surface of the winding cylinder. At this time, if the spring is in normal condition, it can push the lower pusher towards the inner cavity of the winding cylinder and protrude from the inner wall of the winding cylinder.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model can continuously measure and display the tightness of the enameled wire wound on the winding drum. During the production of solenoid valves, it can directly indicate the tightness of the enameled wire, thereby enabling timely rejection of solenoid valves that do not meet the tightness requirements and improving the yield rate of production.

[0017] 2. When the coil frame of this utility model is in the unassembled transport state, the spring is in a relaxed state and will not apply an expansion force to the wound coil. After assembly, the elastic external support component can continuously apply a weak expansion force to the coil, so as to indicate in time when the coil becomes loose, which is convenient for users to judge and maintain.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Reference Figure 1-4 A household solenoid valve coil holder includes a winding body 1, an elastic outer support assembly 2, and a locking mounting component 3. The winding body 1 includes a winding cylinder 11 and limiting rings 12 disposed on the front and rear sides of the winding cylinder 11. Enamelled wire can be wound around the winding cylinder 11 and is restricted by the limiting rings 12 so that it cannot be detached from the winding cylinder 11. The winding cylinder 11 has several mounting grooves 101 symmetrically opened around its circumference to allow the elastic outer support assembly 2 to be inserted. The mounting grooves 101 extend from the front end of the winding cylinder 11 to the middle of the winding cylinder 11 and connect the inner and outer sides of the winding cylinder 11. The outer wall of the winding cylinder 11 also has an extension groove 102 extending from the middle of the winding cylinder 11 to the rear end of the winding cylinder 11. The extension groove 102 communicates with the mounting grooves 101 and only extends to the outside of the winding cylinder 11 without entering the inside of the winding cylinder 11.

[0026] The elastic external support assembly 2 includes an assembly box 21, an upper pusher 22, and a lower pusher 23. The assembly box 21 has an assembly channel 201 that runs vertically through the assembly box. The sliding block 221 of the upper pusher 22 and the lower pusher 23 are respectively fitted into the assembly channel 201 and are in close contact with the inner sidewall of the assembly channel 201. An extension pusher 222 is installed on the part of the sliding block 221 that extends to the upper end of the assembly channel 201. After the assembly box 21 is placed into the mounting groove 101, the extension pusher 222 can be inserted into and fill the extension groove 102, so that the upper pusher 22 can apply an outward pushing force to all the enameled wires wrapped in the winding drum 11. The assembly box 21 has an open window 202 on the side opposite to the extension direction of the extension pusher 222. An indicator piece 223 that can extend out of the open window 202 is installed at the bottom of the sliding block 221. The height of the open window 202 limits the range of movement of the upper pusher 22 in the assembly channel 201.

[0027] At least one spring 24 is connected between the pusher 23 and the sliding block 221. The elasticity generated by the compression of the spring 24 can push the upper pusher 22 and the pusher 23 to move in opposite directions. After the position of the pusher 23 is limited, the spring 24 can provide a continuous pushing force to the upper pusher 22 after being compressed. The front and rear ends of the assembly box 21 are symmetrically equipped with limiting pins 25. The inner wall of the mounting groove 101 is provided with a socket for the limiting pins 25 to be inserted. After the assembly box 21 is placed into the mounting groove 101, the limiting pins 25 will be inserted into the sockets in the inner wall of the mounting groove 101, thereby locking the position of the assembly box 21. After the assembly box 21 is fixedly installed in the mounting groove 101, the indicator 223 expands when it is close to the bottom of the open window 202. The upper surface of the pusher plate 222 is flush with the outer circumference of the winding drum 11. If the spring 24 is in a normal state, it can push the pusher 23 against the inner cavity of the winding drum 11 and protrude from the inner wall of the winding drum 11. It is understood that when the coil frame is installed, the winding drum 11 will be sleeved on the central column and the inner wall will be in close contact with the central column. This will cause the pusher 23 to be partially pushed into the assembly channel 201, which will compress the spring 24. At this time, the elastic force of the spring 24 will be continuously applied to the enameled wire harness tightly wound on the winding drum 11 through the upper pusher 22. If the enameled wire harness becomes loose, the upper pusher 22 will overcome the tightening force of the enameled wire harness and expand outward. After the upper pusher 22 moves, the user can visually observe the position of the indicator plate 223, thereby replacing the coil frame with loose wire harness.

[0028] Preferably, the end of the pusher 23 protruding from the assembly channel 201 has a converging curved surface, so that the winding cylinder 11 can be smoothly pushed into the assembly channel 201 when it is installed on the central column. When the enameled wire is wound, the winding cylinder 11 will be sleeved on the rotating column with protrusions on the outside that can be inserted into the mounting groove 101, so that it can rotate axially with the rotating column to wind the enameled wire. The protrusions on the rotating column can push the pusher 23 further into the assembly channel 201, so that the spring 24 is compressed more and generates greater elastic force, so that the enameled wire overcomes the greater outward expansion force of the upper pusher 22 and wraps around the winding cylinder 11, thereby ensuring the tightness of the winding during subsequent use.

[0029] The locking mounting component 3 is installed on the front end of the elastic external support component 2 after the assembly box 21 is installed in the mounting groove 101, to prevent the elastic external support component 2 from detaching from the mounting groove 101. The locking mounting component 3 has expansion blocks installed on both sides. The side wall of the mounting groove 101 that leads to the outside is provided with a slot that allows the expansion blocks to be inserted. The locking mounting component 3 has a docking slot 301 that allows the insertion of the limiting pin 25. After the expansion block of the locking mounting component 3 is inserted into the slot of the mounting groove 101, the user can use screws to fix the locking mounting component 3 in the mounting groove 101. At this time, the limiting pin 25 is inserted into the docking slot 301, so that the locking mounting component 3 further locks the position of the elastic external support component 2. The locking mounting component 3 also has an indicator window 302 that runs through the front and back. The position and size of the indicator window 302 correspond to the open window 202, so that the indicator piece 223 can be inserted into the indicator window 302 to facilitate the user to observe the position of the indicator piece 223 and intuitively judge the tightness of the enameled wire harness and take corresponding actions.
