Description

Technical Field

[0001] This utility model relates to the field of high-temperature connector technology, and in particular to a high-temperature resistant, heat-resistant, hand-tightening connector. Background Technology

[0002] High-temperature connectors are manufactured using special high-temperature resistant insulating materials, enabling them to operate normally under high-temperature conditions. Suitable for various environments, they feature a highly reliable contact structure. They possess characteristics such as high insulation, high strength, dimensional stability, high radiation resistance, low moisture absorption, corrosion resistance, and excellent sealing performance.

[0003] Currently available high-temperature connectors lack heating, insulation, and anti-scalding functions. During operation, the ferrule nut is tightened onto the ferrule screw on the device using an adjustable wrench, and then heating tape or insulation cotton is wrapped around the outside. While this method is practical, it has several major drawbacks. First, disassembling and assembling this type of high-temperature connector is extremely inconvenient, requiring specialized tools. Second, it is difficult to control the temperature of this connector to match that of the internal fluid, leading to fluid temperature loss and changes in the fluid's properties. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a high-temperature resistant, heat-resistant, hand-tightening connector, which aims to improve the problem that the disassembly and assembly of high-temperature connectors in the prior art is very inconvenient, requires special tools and connectors, and is difficult to control the temperature to be consistent with the internal fluid, resulting in fluid temperature loss and changes in the properties of the fluid.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-temperature resistant and heat-resistant hand-tightening connector, comprising a high-temperature core, a tube core threadedly connected to the front of the outer wall of the high-temperature core, a ferrule nut fixedly connected to the tube core by front and rear ferrules, a heat insulation tile fixedly connected to the bottom of the outer wall of the high-temperature core, a rotating cylinder, a heat insulation cylinder and a hand-tightening cylinder threadedly connected to the front of the heat insulation tile by a threaded rod, and heat insulation stop blocks provided on both the upper and lower sides of the high-temperature core.

[0006] As a further description of the above technical solution:

[0007] The high-temperature column core has a heat insulation and weight reduction groove at the front of its outer wall, and a pagoda-shaped clamping ring at the rear of its outer wall. The external pipeline of the heat insulation and weight reduction groove and the clamping ring are in contact.

[0008] As a further description of the above technical solution:

[0009] The high-temperature column core has a heating rod mounting hole at the front, a heating rod is installed inside the heating rod mounting hole, and a temperature sensor is installed inside the heating rod.

[0010] As a further description of the above technical solution:

[0011] Two stop slots are opened in the middle of the outer part of the high-temperature column core, and the two stop slots and the two heat insulation stop blocks are engaged with each other.

[0012] As a further description of the above technical solution:

[0013] The outer wall of the heat-insulating stop block is fixedly connected to decorative tiles by bolts.

[0014] As a further description of the above technical solution:

[0015] Both the heat insulation tile and the hand-tightening cylinder are equipped with synchronous limiting grooves to transmit the torque of the hand-tightening cylinder to the rotating cylinder.

[0016] As a further description of the above technical solution:

[0017] The front of the rotating cylinder is provided with a hexagonal groove for transmitting torque to the ferrule nut.

[0018] This utility model has the following beneficial effects:

[0019] 1. In this utility model, a pagoda-shaped clamping ring, a stop groove, and a heating rod mounting hole are provided. The external pipeline is directly and tightly clamped to the clamping ring of the high-temperature column core to form a whole. After two Teflon-made heat-insulating stop blocks are installed from both sides to wrap around the high-temperature column core, two decorative tiles are inserted from both sides into the grooves of the heat-insulating stop tiles and then locked with standard studs, which can quickly fix the structure while reducing heat loss.

[0020] 2. In this utility model, the rotating cylinder is made of stainless steel, the heat insulation cylinder and heat insulation tile are made of Teflon, and the hand-twisting cylinder is made of high-temperature resistant carbide. This can effectively prevent the heat on the rotating cylinder from being transferred to the outside of the hand-twisting cylinder, so that the hand-twisting cylinder maintains a relatively low temperature and plays a role in preventing scalding.

[0021] 3. In this utility model, the rotating cylinder, the heat insulation cylinder, the heat insulation tile, and the hand-tightening cylinder are all equipped with synchronous limiting grooves, which effectively transmit the torque on the hand-tightening cylinder to the rotating cylinder. The high-temperature column core and the tube core are connected by a standard screw, and the ferrule nut is fixed to the tube core by the front and rear ferrules. When the tube core exceeds the number of uses or is accidentally damaged, it can be directly replaced, making maintenance convenient.

[0022] 4. In this utility model, a hexagonal groove is provided at the front of the rotating cylinder, which is used to transmit torque to the ferrule nut. By manually rotating the hand-tightening cylinder in both directions, the operator can tighten and loosen the ferrule nut without the need for tools.

[0023] 5. In this utility model, the heating rod has a built-in temperature sensor, and the temperature control system controls the heating rod to heat the high-temperature column core and tube core to the set temperature, ensuring that the fluid is transported through the connector without heat loss, thus ensuring the stability of the fluid's physical and chemical properties and realizing lossless fluid transport.

Detailed Implementation

[0028] 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.

[0029] Reference Figures 1-2This utility model provides an embodiment of a high-temperature resistant, heat-resistant, hand-tightening connector, comprising a high-temperature core 1, with a tube 2 threadedly connected to the front of the outer wall of the high-temperature core 1. The threaded connection allows the tube 2 to be securely mounted on the high-temperature core 1, facilitating disassembly and installation. Different specifications of tube 2 can be flexibly replaced according to actual needs. A retaining nut 9 is fixedly connected to the tube 2 via front and rear retaining sleeves 10. The front and rear retaining sleeves 10 can position and clamp the tube 2. Used in conjunction with the retaining nut 9, it ensures the tube 2 remains stable during connector operation and prevents loosening. A heat-insulating tile 5, made of Teflon, is fixedly connected to the bottom of the outer wall of the high-temperature core 1. The heat-insulating tile 5 effectively blocks the heat from the high-temperature core 1 from being transferred to the bottom of the connector. The front of the heat-insulating tile 5 is threaded... The rod is threadedly connected to a rotating cylinder 3, a heat insulation cylinder 4, and a hand-tightening cylinder 8, allowing them to rotate around the threaded rod. The rotating cylinder 3 is made of stainless steel, the heat insulation cylinder 4 is made of Teflon, and the hand-tightening cylinder 8 is made of high-temperature resistant acetal steel. When installing and disassembling the connector, rotating the hand-tightening cylinder 8 drives the rotating cylinder 3 and the heat insulation cylinder 4 to rotate synchronously, enabling quick installation and disassembly of the connector. The operation is convenient and fast. Heat-insulating stop blocks 6 are provided on both the upper and lower sides of the high-temperature core 1. The heat-insulating stop blocks 6 are made of Teflon. On the one hand, the heat-insulating stop blocks 6 can further prevent the heat of the high-temperature core 1 from spreading upward and downward. On the other hand, they can also position and stop other components, ensuring that each component maintains the correct position during the operation of the connector.

[0030] Reference Figure 1 and Figure 2 A heat insulation and weight reduction groove 15 is provided on the front of the outer wall of the high-temperature core 1. The heat insulation and weight reduction groove 15 can reduce the weight of the high-temperature core 1 without affecting its strength, thereby reducing material costs. At the same time, it can also play a certain role in heat insulation, slowing down the heat transfer from the front of the high-temperature core 1 to the outside. A clamping ring 12 is provided at the rear of the high-temperature core 1. The external pipeline of the heat insulation and weight reduction groove 15 and the clamping ring 12 abut against each other. By clamping the external pipeline of the heat insulation and weight reduction groove 15 with the clamping ring 12, the pipeline can be firmly fixed to the high-temperature core 1, ensuring a tight connection between the pipeline and the high-temperature core 1, preventing leakage, and ensuring the sealing performance of the connector.

[0031] Reference Figure 1 and Figure 2The high-temperature core 1 has a heating rod mounting hole 14 at the front, and a heating rod 11 is installed inside the heating rod mounting hole 14. The heating rod 11 can adjust the temperature of the high-temperature core 1 according to the actual working requirements to keep it within a suitable working temperature range. A temperature sensor is installed inside the heating rod 11. The temperature sensor can monitor the temperature of the heating rod 11 in real time and feed the temperature signal back to the control system. When the temperature is too high or too low, the control system can adjust the power of the heating rod 11 in time to achieve precise control of the temperature of the high-temperature core 1.

[0032] Reference Figure 1 and Figure 2 Two stop slots 13 are opened in the middle of the outer part of the high temperature column core 1. The two stop slots 13 and the two heat insulation stop blocks 6 are snapped together. The snapping structure can accurately install the heat insulation stop blocks 6 on the high temperature column core 1, prevent the heat insulation stop blocks 6 from rotating or shifting on the high temperature column core 1, and ensure that the heat insulation stop blocks 6 can stably play the role of heat insulation and stopping.

[0033] Reference Figure 1 The outer wall of the heat insulation stop block 6 is fixedly connected to the decorative tile 7 by bolts. The decorative tile 7 not only provides a certain degree of protection for the heat insulation stop block 6, preventing it from being impacted and damaged by external forces, but also assists in heat insulation to a certain extent, further improving the heat insulation performance of the connector.

[0034] Reference Figure 1 Both the heat insulation tile 5 and the hand-tightening cylinder 8 are equipped with synchronous limiting grooves to transmit the torque of the hand-tightening cylinder 8 to the rotating cylinder 3. When the operator twists the cylinder 8, the synchronous limiting grooves can ensure that the torque of the hand-tightening cylinder 8 is accurately transmitted to the rotating cylinder 3, so that the rotating cylinder 3 and the hand-tightening cylinder 8 rotate synchronously and avoid slippage.

[0035] Reference Figure 1 The front of the rotating cylinder 3 is provided with a hexagonal groove, which is used to transmit torque to the ferrule nut 9. The hexagonal groove can cooperate with a hexagonal wrench to accurately transmit torque to the ferrule nut 9, making it easy to tighten and loosen the ferrule nut 9. The design of the hexagonal groove can ensure the stability and reliability of torque transmission and prevent slippage during operation.

[0036] Working Principle: During use, this high-temperature resistant, heat-resistant, hand-tightening connector allows the external tubing to be directly and tightly connected to the clamping ring 12 of the high-temperature core 1, forming a unified whole. Two Teflon-coated heat-insulating stop blocks 6 are installed from both sides, encasing the high-temperature core 1. Two decorative tiles 7 are inserted from both sides into the grooves of the heat-insulating stop blocks 6 and secured with standard studs, ensuring quick fixation while minimizing heat loss. The hand-tightening cylinder 8 maintains a relatively low temperature, preventing burns. Torque is transmitted to the rotating cylinder 3 via the hand-tightening cylinder 8, allowing operators to tighten and loosen the ferrule nut 9 manually by rotating the cylinder 3 in both directions without the need for tools. The temperature control system controls the heating rod 11 to heat the high-temperature core 1 and the tube core 2 to the set temperature, ensuring no heat loss during fluid transport through the connector, maintaining the stability of the fluid's physical and chemical properties, and achieving lossless fluid transport.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
