Description

Technical Field

[0001] The utility model relates to the technical field of external taper sleeves, and specifically relates to an external taper sleeve. Background Art

[0002] The insulating sleeve of an inflatable cabinet usually uses an insulating sleeve made of epoxy resin material sleeved on a conductive rod made of copper. However, the shrinkage rates of the epoxy resin material and the copper part are different, resulting in a gap between the copper conductive rod and the insulating material at high temperatures, thus causing air leakage, which affects the performance and reliability of the insulating sleeve. There is a need for an external taper sleeve now.

[0003] After retrieval, the patent number is 201621266835.2, and the name is an insulating sleeve with a temperature measuring element, which includes an insulating sleeve body and a connecting part. The insulating sleeve is of a hollow structure. A groove is opened inside the insulating sleeve. A temperature measuring element is placed in the groove. An insulating cover plate is arranged on the groove. Fine holes corresponding to and communicating with the position of the groove are arranged outside the insulating sleeve. The temperature signal of the temperature measuring element is transmitted outward from the fine holes. Compared with the existing technology of remotely measuring the temperature of the sleeve by infrared, a groove is arranged inside the insulating sleeve of the utility model.

[0004] Existing external taper sleeves still have some disadvantages to a certain extent. When an external taper sleeve is used, it needs to be installed first, and the stability requirement after installation is relatively high. The existing external taper sleeves are not stable enough during installation, which makes the structure of the external taper sleeve not firm enough during use; when an external taper sleeve is used, the requirement for its sealing performance is relatively high. The sealing performance of the existing external taper sleeves during use needs to be further improved, which makes it impossible to fill the gap between the external taper sleeve body and the conductive core rod at high temperatures during use, and cannot ensure the sealing of the sleeve of the external taper sleeve, reducing the reliability and service life of the external taper sleeve; when an external taper sleeve is used, it needs to be insulated and high-temperature resistant. The insulation and high-temperature resistance performance of the existing external taper sleeves during use is not good enough, which makes it impossible to achieve the purpose of real-time measuring the temperature of the external taper sleeve body during use, and easily leads to the phenomenon of safety accidents caused by too high temperature at the conductive core rod.

The arc-shaped clamping parts 404 and the surfaces of the connecting blocks 403 are slidably matched with each other. The arc-shaped clamping parts 404 and the surfaces of the conductive core rod 101 are clamped and matched with each other. Stretching springs 405 are installed on the surfaces of the arc-shaped clamping parts 404. One end of the stretching spring 405 is fixed to the surface of the connecting block 403. Guiding sliders 401 are installed on the surfaces of the installation parts 103. The guiding sliders 401 and the inner wall of the conductive core rod 101 are slidably matched with each other. Positioning clamping parts 402 are installed on the surfaces of the guiding sliders 401. The positioning clamping parts 402 and the inner wall of the installation connection groove 102 are clamped and matched with each other.

[0028] During implementation, under the action of the guiding slider 401, the installation part 103 is guided, so that the guiding slider 401 drives the positioning clamping part 402 to be clamped to the inner wall of the conductive core rod 101. Under the action of the positioning clamping part 402, the installation part 103 is prevented from loosening. At this time, the installation part 103 drives the connecting block 403 to move to one side of the conductive core rod 101.

[0029] Furthermore, as Figure 2 and Figure 5As shown, a high temperature resistant mechanism 2 is provided on the surface of the conductive core rod 101, and the interior of the high temperature resistant mechanism 2 includes a fixed box 201, a dustproof net 202 and a high temperature resistant component 203.

A fixed box 201 is installed on the surface of the conductive core rod 101, and a dustproof net 202 is provided on the surface of the fixed box 201. The dustproof net 202 and the surface of the fixed box 201 are engaged with each other, and a temperature detector body 2031 for monitoring the temperature is installed inside the fixed box 201. The inner walls of the fixed box 201 and the conductive core rod 101 are both provided with through hole bodies 2033 at equal intervals, and the through hole body 2033 is connected to the interior of the fixed box 201, and a heat conducting plate 2032 for conducting heat to the conductive core rod 101 is installed inside the conductive core rod 101.

[0030] During implementation, the temperature inside the conductive core rod 101 can be monitored under the action of the temperature detector body 2031 inside the fixed box 201. The user places the dustproof net 202 on the surface of the fixed box 201, and the user pushes the dustproof net 202 so that the dustproof net 202 is stuck to the surface of the fixed box 201. The interior of the fixed box 201 is dustproofed under the action of the dustproof net 202. When the temperature detector body 2031 detects that the temperature on the surface of the outer cone sleeve body 1 and the conductive core rod 101 is too high, at this time, under the action of the heat conductive plate 2032, the heat inside the conductive core rod 101 is exported through the through-hole body 2033, and the heat is discharged from the inside of the outer cone sleeve body 1 and the conductive core rod 101 through the dustproof net 202, thereby real-time monitoring of the temperature on the surface of the outer cone sleeve body 1 and the conductive core rod 101 is performed to achieve the insulation and high temperature resistance function of the outer cone sleeve.

[0031] Furthermore, if Figure 2 and Figure 6 As shown, the inner wall of the outer cone sleeve body 1 and the surface of the conductive core rod 101 are both provided with a sealing mechanism 3, the interior of the sealing mechanism 3 includes an insulating sleeve 301, a sealing plate 302, an epoxy resin layer 303 and a sealing gasket 304, the inner wall of the outer cone sleeve body 1 is adhered with a sealing gasket 304, the surface of the sealing gasket 304 is provided with an epoxy resin layer 303, the epoxy resin layer 303 is bonded to the surface of the sealing gasket 304, the inner part of the outer cone sleeve body 1 is provided with an insulating sleeve 301, the insulating sleeve 301 is bonded to the surface of the epoxy resin layer 303 away from the sealing gasket 304, the surface of the insulating sleeve 301 is covered with a sealing plate 302, the surface of the sealing plate 302 is bonded to the surface of the insulating sleeve 301, and the surface of the sealing plate 302 is in contact with the surface of the conductive core rod 101.

[0032] During implementation, the airtightness between the outer conical sleeve body 1 and the conductive core rod 101 is enhanced by the combined action of the gasket 304 and the epoxy resin layer 303. The sealing performance between the outer conical sleeve body 1 and the conductive core rod 101 is made higher by the combined action of the insulating sleeve 301 and the sealing plate 302, avoiding the occurrence of gaps between the outer conical sleeve body 1 and the conductive core rod 101, which may cause damage to the outer conical sleeve body 1 and the conductive core rod 101 during use, so as to achieve the function of sealing the outer conical sleeve.

[0033] Working principle: During use, first place the outer conical sleeve body 1 at the designated position. The user places the installation part 103 on one side of the outer conical sleeve body 1. The user pushes the installation part 103, causing the installation part 103 to drive the guiding slider 401 to slide inside the conductive core rod 101. At this time, under the action of the guiding slider 401, the installation part 103 is guided, causing the guiding slider 401 to drive the positioning clip 402 to be clamped to the inner wall of the conductive core rod 101. Under the action of the positioning clip 402, the installation part 103 is prevented from loosening. At this time, the installation part 103 drives the connecting block 403 to move to one side of the conductive core rod 101. Under the elastic force of the extension spring 405, the arc-shaped clip 404 is driven to move, causing the arc-shaped clip 404 to be clamped to the surface of the conductive core rod 101. Under the action of the arc-shaped clip 404, the installation part 103 is prevented from loosening, avoiding the loosening of the outer conical sleeve body 1 during use, so as to achieve the function of stably installing the outer conical sleeve, so that the outer conical sleeve can be stably installed at the designated position during use, making the structure of the outer conical sleeve more firm during use.

[0034] Subsequently, the airtightness between the outer conical sleeve body 1 and the conductive core rod 101 is enhanced by the combined action of the gasket 304 and the epoxy resin layer 303. The sealing performance between the outer conical sleeve body 1 and the conductive core rod 101 is made higher by the combined action of the insulating sleeve 301 and the sealing plate 302, avoiding the occurrence of gaps between the outer conical sleeve body 1 and the conductive core rod 101, which may cause damage to the outer conical sleeve body 1 and the conductive core rod 101 during use, so as to achieve the function of sealing the outer conical sleeve. Thus, during use at high temperatures, the gap between the outer conical sleeve body 1 and the conductive core rod 101 can be filled, ensuring the sealing performance of the outer conical sleeve and improving the reliability and service life of the outer conical sleeve.

[0035] Subsequently, under the action of the internal temperature detector body 2031 of the fixed box 201, the temperature inside the conductive mandrel 101 can be monitored. The user places the dust-proof net 202 on the surface of the fixed box 201, and the user pushes the dust-proof net 202 so that the dust-proof net 202 is snapped onto the surface of the fixed box 201. Under the action of the dust-proof net 202, dust prevention is carried out inside the fixed box 201. When the temperature detector body 2031 monitors that the temperatures on the surfaces of the outer cone sleeve body 1 and the conductive mandrel 101 are too high, at this time, under the action of the heat conduction plate 2032, the heat inside the conductive mandrel 101 is exported through the through-hole body 2033, and the heat is discharged from the inside of the outer cone sleeve body 1 and the conductive mandrel 101 through the dust-proof net 202, so as to monitor the temperatures on the surfaces of the outer cone sleeve body 1 and the conductive mandrel 101 in real time, so as to realize the function of the outer cone sleeve being insulated and high-temperature resistant, so that when the outer cone sleeve is used, the purpose of measuring the temperature of the outer cone sleeve body 1 in real time can be achieved, and the temperature on the surface of the conductive mandrel 101 can be measured more accurately, avoiding the phenomenon of safety accidents caused by too high temperature at the conductive mandrel 101, and finally completing the use work of the outer cone sleeve.

[0036] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and without departing from the spirit or basic characteristics of the present utility model, the present utility model can be implemented in other specific forms.
