Description

Technical Field

[0001] This application relates to the field of lubricant heating technology, and in particular to a thread lubricant heating device. Background Technology

[0002] Threaded connections are the primary method of connection between various components in many mechanical devices. For fasteners in critical areas, thread lubricant is often applied to the engagement point during torque-based installation. Thread lubricant reduces the coefficient of friction, prevents seizing, and provides corrosion protection, making it crucial for the reliability of the connection.

[0003] At low temperatures, thread lubricant is more viscous and has poor fluidity.

[0004] If applied directly without heating, problems such as low application efficiency, uneven application, and applying too much or too little lubricant will occur during fastener installation. This will result in insufficient and uneven preload in the entire threaded connection system, posing a safety hazard to the entire equipment. If too much lubricant is applied in one area, it will be squeezed out during screwing, resulting in significant waste and pollution of the working environment.

[0005] Existing heating methods, such as water baths and ovens, suffer from problems such as cumbersome operation, inaccurate temperature control, low efficiency, and lack of portability, making them unsuitable for on-site or mobile operations. While some handheld heating devices offer a degree of portability, they often face limitations such as inaccurate temperature control, low heating efficiency, high energy consumption, inadequate safety design, and reliance on mains power, thus restricting their application scenarios.

[0006] Therefore, there is a need for a lubricant heating device that can overcome the above-mentioned defects, providing efficient, precise, portable and safe heating capabilities, and adapting to diverse working environments, thereby comprehensively improving the coating efficiency and application effect of lubricants. Utility Model Content

[0007] The purpose of this application is to provide a thread lubricant heating device to adapt to diverse working environments, thereby comprehensively improving the coating efficiency and application effect of the lubricant.

[0008] To achieve the above objectives, this application provides a thread lubricant heating device, comprising:

[0009] The cylinder is used to hold the lubricant that needs to be heated;

[0010] The cover is located at the opening of the cylinder and is used to open and close the cylinder.

[0011] A heating plate is located at the bottom of the cylinder and is used to heat the lubricant inside the cylinder. A protective cover is provided at the outer end of the heating plate, and the first electrical contact point is integrated on the protective cover.

[0012] A heating base is located at the bottom of the heating plate. A control unit is housed within the heating base, and a second electrical contact point is located at the control unit. The first electrical contact point is elastically connected to the second electrical contact point.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] It should be noted that the directional terms such as "upper end," "lower end," "left side," and "right side" mentioned below are defined based on the accompanying drawings in the instruction manual.

[0032] Please see Figures 1 to 3 A thread lubricant heating device includes a cylinder 2, a cover 1, a heating plate 23, and a heating base 3.

[0033] The cylinder 2, serving as a container for the lubricant, forms a relatively sealed space with the cover 1. This structure effectively prevents the lubricant from being contaminated by the external environment during heating and reduces the escape of volatile components from the lubricant, ensuring the quality of the lubricant and the heating effect. Simultaneously, the sealed environment also helps concentrate heat, improving heating efficiency.

[0034] The heating plate 23 is crucial for raising the lubricant temperature. It comes into direct or indirect contact with the lubricant and transfers heat, ensuring that the lubricant is heated evenly and efficiently to the required temperature, preparing it for subsequent use.

[0035] The heating base 3 not only provides stable support for the entire device, but more importantly, it integrates the circuitry of the heating plate 23 and the control unit 31. This design, which separates the heating and control functions from the carrier container, brings significant advantages in safety and convenience. On the one hand, it keeps the high-temperature heating element away from the operator, reducing the risk of burns; on the other hand, when cleaning the cylinder or changing the lubricant is required, the cylinder 2 can be easily removed from the heating base 3, making cleaning and maintenance simpler and easier. Overall, this modular design improves the safety and efficiency of the lubricant heating process.

[0036] The cylinder 2 is used to hold the lubricant that needs to be heated. In some embodiments, the cylinder 2 is a cylindrical structure with one end open.

[0037] The primary function of cylinder 2 in this lubricant heating device is to directly hold the lubricant to be heated. This design ensures that the lubricant is properly contained, providing a reliable carrier for the subsequent heating process. The cylindrical structure is generally simple to manufacture, cost-effective, and possesses good strength and stability, effectively resisting the weight of the internal lubricant and potential thermal expansion during heating. The open-end design facilitates the filling and removal of the lubricant. Whether adding lubricant for the first time, removing it after heating, or cleaning the cylinder, this opening provides a wide passage, making the entire process more convenient, efficient, and less prone to spillage.

[0038] The cover 1 is disposed at the opening of the cylinder 2 and is used to open and close the cylinder 2. In some embodiments, in order to close the cylinder 2, a preferred solution is that the outer side wall of the cylinder 2 near the opening is provided with a first connecting thread 21, and the cover 1 is connected to the cylinder 2 through the first connecting thread 21.

[0039] The main function of the cover 1 is to effectively manage the opening and closing of the cylinder 2, ensuring that when the cover 1 is closed, the cylinder 2 containing the lubricant forms a relatively closed or semi-closed space. This effectively prevents external dust, impurities, and other contaminants from entering the lubricant, thus ensuring the purity of the lubricant and its quality after heating. Simultaneously, the sealed environment also helps reduce the escape of volatile components from the lubricant during the heating process.

[0040] When the outer wall of the cylinder 2 near the opening is provided with a first connecting thread 21, and the cover 1 is connected to the cylinder 2 through this thread, this threaded connection method further enhances the practicality and reliability of the device. The threaded connection not only provides a stable and easy-to-operate connection method, ensuring that the cover 1 can be firmly fixed to the cylinder 2 and is not easily loosened even during heating or handling, but also typically provides better sealing performance. The helical action compresses the cover, further enhancing the protection of the lubricant, effectively preventing heat loss and lubricant leakage, and improving the efficiency and safety of the entire heating device.

[0041] Heating plate 23 is located at the bottom of cylinder 2 and is used to heat the lubricant inside cylinder 2. A protective cover 24 is provided at the outer end of heating plate 23, and the first electrical contact point is integrated on the protective cover 24.

[0042] In some embodiments, the first electrical contact includes a live wire, a neutral wire, a ground wire, and a first contact.

[0043] The heating plate 23, as the core heating unit of the lubricant heating device, is located at the bottom of the cylinder 2. This location ensures that heat can be efficiently and evenly conducted from the bottom to the lubricant inside the cylinder, thereby achieving rapid heating and ensuring uniform heating effect.

[0044] To ensure safety, a protective cover 24 is provided at the outer end of the heating plate 23. The protective cover 24 provides physical protection for the heating element, preventing external impact or foreign object intrusion. Moreover, it integrates the first electrical connection contact point, which unifies and effectively hides the electrical interface, improves the safety of user operation, avoids the risk of electric shock caused by exposed contacts, and makes the device look cleaner.

[0045] In specific embodiments, these first electrical connection contacts typically include a live wire, a neutral wire, and a ground wire. These three wires constitute a standard, safe AC power supply and protection circuit, ensuring the normal operation of the heating plate and the personal safety of the user in the event of a leakage.

[0046] Heating base 3 is located at the bottom of heating plate 23. Heating base 3 is equipped with control unit 31. Control unit 31 is equipped with second electrical contact point. First electrical contact point is elastically connected to second electrical contact point. Second electrical contact point includes live wire, neutral wire, ground wire and second contact 32.

[0047] In this paper, the heating base 3 serves both as a support and a control unit. The heating base 3 is located at the bottom of the heating plate 23, forming a stable base that supports the heating plate and integrates subsequent control functions.

[0048] To achieve the electrical connection between the heating plate 23 and the control unit 31, a second electrical contact point is specifically provided at the control unit 31. This design allows the heating plate 23 to achieve a quick and reliable plug-and-play electrical connection during installation or maintenance through the flexible connection between the first and second electrical contact points. This flexible connection can compensate for manufacturing tolerances, ensure the tightness and stability of the connection, and provide convenience during assembly and disassembly, reducing operational difficulty and potential damage risks.

[0049] In some embodiments, the cylinder 2 is a hollow cylinder with a second connecting thread 25. The heating base 3 has a groove at the top and a base connecting thread that matches the second connecting thread 25 on the inner wall of the groove. The heating base 3 is threadedly connected to the bottom of the cylinder 2.

[0050] In some embodiments, the heating base 3 also includes a lithium battery 33. The heating base 3 has an external power interface 34 and a mains power interface 35. The power interface 34 is used to charge the lithium battery 33. The heating base 3 provides power to the heating plate 23 via the mains power interface 35 or the lithium battery 33. The power interface 34 is a Type-C interface used to charge the lithium battery 33.

[0051] This heating device further enhances its portability and power supply flexibility, specifically by integrating a lithium battery 33 within the heating base 3. To support this power configuration, the heating base 3 is equipped with two key interfaces: a power device interface 34, specifically designed for charging the built-in lithium battery 33; and an AC power interface 35, for connecting to external AC power. Accordingly, the heating plate 23 can be powered directly by the AC power interface 35 or by the internal lithium battery 33, expanding the device's application scenarios. Furthermore, to improve user experience and interface compatibility, the power device interface 34 adopts the universal Type-C interface standard, ensuring the charging of the lithium battery 33.

[0052] In some embodiments, the heating base 3 is also provided with operation buttons on the outside. The operation buttons include at least a setting button 36, a heating button 38, and a heat preservation button 39. The setting button 36 is used to enter and / or exit the parameter setting page of the heating device. The heating button 38 is used to start the heating process of the lubricant. The heat preservation button 39 is used to start and / or stop the temperature preservation function of the heating device.

[0053] In some embodiments, an external temperature sensor 22 is also provided at the bottom of the cylinder 2. The signal from the external temperature sensor 22 is used to control the control unit 31 to heat the heating plate 23. The heating base 3 is also provided with a temperature display area 37, and the temperature detected by the external temperature sensor 22 is also displayed through the temperature display area 37.

[0054] The advantages of heating the thread lubricant using the above method are as follows: First, heating the thread lubricant effectively reduces its viscosity, making it easier to apply and significantly improving application efficiency. Second, the heated thread lubricant has better fluidity, allowing it to penetrate more evenly and fully into the fine gaps of threads or other mating parts, greatly enhancing lubrication and rust prevention, thereby improving the reliability of the entire connection system. Third, because the heated thread lubricant spreads more easily, it avoids localized accumulation that can be squeezed out during the screwing process, effectively preventing pollution of the working environment and indirectly achieving economical use of the thread lubricant. Furthermore, this device also has a certain heat retention capacity, allowing the heated lubricant to maintain good fluidity for a longer period. Finally, the replaceable design of the heating base 3 not only extends the service life of the entire device, but more importantly, after disassembling the heating base 3, the cleaning process of the main body becomes safer and more convenient.
