Abstract
Description
Technical Field
[0001] This utility model relates to the field of ceramic heating coil technology, specifically a ceramic heating coil that can protect wires. Background Technology
[0002] A ceramic heating coil is a heating device made of ceramic material. It is usually a ring structure that can convert electrical energy into heat energy and is used to heat industrial equipment, household appliances, etc. The ceramic heating coil is equipped with wires to supply power to the heating ceramic plate.
[0003] When the existing ceramic heating coil is in use, the surrounding temperature rises, causing the outer sheath of the wire to soften. When bending the wire, the wire is easily damaged when it gets stuck at the outlet hole of the ceramic seat. It is not convenient to protect the bending point. In addition, when disassembling the wire, the protective shell on the outside of the ceramic seat needs to be removed, which is not convenient to directly and quickly disassemble the wire, and the disassembly process is relatively cumbersome. Utility Model Content
[0004] The purpose of this invention is to provide a ceramic heating coil that can protect the wires, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A ceramic heating coil for protecting wires includes a heating coil body, a ceramic seat disposed on the outer side of the heating coil body, and a protective shell disposed on the outer side of the heating coil body outside the ceramic seat, comprising:
[0007] A connecting component is disposed on one side surface of the ceramic base;
[0008] A protective component is disposed on the outside of the protective shell. The protective component includes a threaded sleeve, an adapter is screwed into the threaded sleeve, a conductive block is fixedly embedded on one side surface of the adapter, and a No. 2 wire electrically connected to the conductive block is fixedly installed on the other side surface of the adapter.
[0009] The limiting component is located inside the protective housing.
[0010] Furthermore, a threaded groove is provided on one side surface of the protective shell, and an external thread is fixedly installed at the lower end of the outer surface of the threaded sleeve. The threaded sleeve is screwed into the threaded groove through the external thread.
[0011] Furthermore, a protective sleeve is fixedly installed on the other side surface of the adapter, located on the outer surface of the second conductor, and multiple metal wires are fixedly embedded inside the protective sleeve at equal angles.
[0012] Furthermore, the connection component includes:
[0013] The connector is fixedly installed on one side surface of the ceramic base;
[0014] The first wire is fixedly connected to one side of the connector and electrically connected to the connector of the ceramic base;
[0015] A conductive groove is formed on one side surface of the connector and is electrically connected to the first wire.
[0016] The positioning hole is located on one side surface of the connector.
[0017] Preferably, the conductive block is movably connected to the conductive groove at the corresponding position, and a positioning rod is fixedly installed on one side surface of the adapter, and the positioning rod is movably connected to the positioning hole.
[0018] Furthermore, the limiting component includes:
[0019] Two U-shaped sliding sleeves are symmetrically and fixedly installed on one side of the inner surface of the protective shell;
[0020] Two sliders are slidably connected inside the U-shaped sleeve;
[0021] Two connecting plates are fixedly installed on the lower surfaces of the slider and the U-shaped sleeve, respectively.
[0022] Preferably, a spring is fixedly connected between two adjacent connecting plates, a stepped groove is symmetrically opened on one side surface of the protective shell, a stepped rod is movably embedded in the stepped groove, a limit groove is symmetrically opened on the outer surface of the threaded sleeve, and the slider is movably inserted into the limit groove at the corresponding position.
[0023] Compared with the prior art, the beneficial effects of this utility model are:
[0024] 1. Through the electrical connection between the conductive groove and the first wire, the conductive block, after being inserted into the conductive groove, can provide power to the heating coil body, enabling the heating coil body to work normally. After the conductive block is inserted into the conductive groove, the threaded sleeve is screwed on, causing it to screw down inside the threaded groove. By screwing the threaded sleeve on one side of the protective shell, the conductive block can be quickly electrically connected to the ceramic seat. This protects the bending point of the second wire from the protective sleeve. At the same time, the quick removal of the threaded sleeve allows the second wire to be quickly removed, facilitating the maintenance and replacement of the heating coil body and the second wire.
[0025] 2. When the threaded sleeve is screwed down, the stepped rod is squeezed down, causing the stepped rod to push the slider to one side. After the threaded sleeve is screwed into place, the limiting groove is aligned with the slider, and the slider is stuck inside the limiting groove with slight contact, which increases the connection firmness of the threaded sleeve.

Detailed Implementation
[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] Please see Figure 1-5In this embodiment of the present invention, a ceramic heating coil that can protect the conductor includes a heating coil body 1, a ceramic seat 102 disposed on the outer side of the heating coil body 1, and a protective shell 101 disposed on the outer side of the heating coil body 1 outside the ceramic seat 102. A connecting component 2 is disposed on one side surface of the ceramic seat 102, and a protective component 3 is disposed on the outer side of the protective shell 101. The protective shell 101 protects the ceramic seat 102. The protective component 3 includes a threaded sleeve 301, an adapter 304 screwed into the threaded sleeve 301, a conductive block 305 fixedly embedded on one side surface of the adapter 304, and a second conductor 306 electrically connected to the conductive block 305 fixedly mounted on the other side surface of the adapter 304. A threaded groove 103 is formed on one side surface of the protective shell 101, and an external thread 302 is fixedly mounted at the lower end of the outer surface of the threaded sleeve 301. The threaded sleeve 301 is screwed into the threaded groove 103 via the external thread 302. A limiting component 4 is disposed inside the protective shell 101.
[0034] Specifically, by screwing the threaded sleeve 301 into the threaded groove 103, the conductive block 305 is inserted into the conductive groove 202, and the second wire 306 and the first wire 204 are electrically connected. At the same time, it is easy to disassemble the second wire 306. The connection between the protective shell 101 and the protective component 3 is strengthened by the limiting component 4.
[0035] Example 1
[0036] like Figure 2-4 As shown, in this embodiment, the connecting component 2 includes: a connecting seat 201 fixedly installed on one side surface of the ceramic seat 102; a first wire 204 fixedly connected to one side of the connecting seat 201 and electrically connected to the connector of the ceramic seat 102; a conductive groove 202 opened on one side surface of the connecting seat 201 and electrically connected to the first wire 204; a positioning hole 203 opened on one side surface of the connecting seat 201; and the positioning hole 203 and the positioning rod 307 are movably inserted to fix the adapter 304 and reduce the torque on the conductive block 305.
[0037] In this embodiment, through the electrical connection between the conductive groove 202 and the first wire 204, the conductive block 305 can provide power to the heating coil body 1 after being inserted into the conductive groove 202, so that the heating coil body 1 can work normally.
[0038] like Figure 3 and Figure 4As shown, in this embodiment, a protective sleeve 308 is fixedly installed on the other side surface of the adapter 304, located on the outer surface of the second conductor 306. Multiple metal wires 309 are fixedly embedded at equal angles inside the protective sleeve 308. The metal wires 309 can be bent, fixing the angle when the protective sleeve 308 bends with the second conductor 306, while limiting the bending angle of the second conductor 306. The conductive block 305 is movably inserted into the conductive groove 202 at the corresponding position. A positioning rod 307 is fixedly installed on one side surface of the adapter 304, and the positioning rod 307 is movably inserted into the positioning hole 203.
[0039] In practice, after the conductive block 305 is inserted into the conductive groove 202, the threaded sleeve 301 is screwed in, causing it to screw down inside the threaded groove 103. At the same time, through its screwing connection with the adapter 304, the adapter 304 is kept stationary under the limiting action of the positioning rod 307 and the positioning hole 203. Thus, by screwing the threaded sleeve 301 on one side of the protective shell 101, the conductive block 305 is quickly electrically connected to the ceramic seat 102. The protective sleeve 308 protects the bend of the second wire 306. At the same time, the second wire 306 can be quickly disassembled through the quick disassembly of the threaded sleeve 301, which facilitates the maintenance and replacement of the heating coil body 1 and the second wire 306.
[0040] Example 2
[0041] Based on Embodiment 1, in order to compensate for the problem of poor connection between the threaded sleeve 301 and the protective shell 101.
[0042] like Figure 5 As shown, in this embodiment, the limiting component 4 includes: two U-shaped sliding sleeves 401 symmetrically fixedly installed on one side surface inside the protective shell 101; two sliders 402 slidably connected inside the U-shaped sliding sleeves 401; the contact end of the sliders 402 with the limiting groove 303 is set as an arc surface to facilitate separation and engagement with the limiting groove 303; two connecting plates 403 are respectively fixedly installed on the lower surfaces of the sliders 402 and the U-shaped sliding sleeves 401; a spring 404 is fixedly connected between two adjacent connecting plates 403; a stepped groove 104 is symmetrically opened on one side surface of the protective shell 101; a stepped rod 405 is movably embedded in the stepped groove 104; a limiting groove 303 is symmetrically opened on the outer surface of the threaded sleeve 301; and the sliders 402 are movably inserted into the limiting groove 303 at the corresponding positions.
[0043] In practice, when the threaded sleeve 301 is screwed down, the stepped rod 405 is pressed down, causing the stepped rod 405 to push the slider 402 to one side. After the threaded sleeve 301 is screwed into place, the limiting groove 303 is aligned with the slider 402, and the slider 402 is stuck inside the limiting groove 303 and makes slight contact (after applying a certain force, the slider 402 can be moved out of the limiting groove 303), which increases the connection firmness of the threaded sleeve 301.
[0044] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
[0045] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider 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.
