[0002] Thermal grease is a thermally conductive silicone grease-like compound made primarily of silicone with added heat-resistant and thermally conductive materials. It is a high thermal conductivity insulating silicone material. When devices need to be coated with thermal grease during processing and production, the coating process is usually carried out using a coating fixture. Existing coating fixtures are equipment used for thermal grease coating. The coating fixtures facilitate the support and placement of devices of different thicknesses during the coating process, making the coating of thermal grease convenient and improving the coating effect.

[0003] Existing coating fixtures, when applying thermal grease, directly place the device to be coated inside the placement frame, and the distance between the placement frame and the mesh is fixed. This allows for coating only devices of matching thickness. When coating devices of different thicknesses, it is inconvenient to adjust the placement height, resulting in inconvenient or even impossible coating. This affects the ease of adjusting the coating position and the coating effect of the coating fixture. Therefore, this utility model proposes a thermal grease coating fixture. Utility Model Content

[0004] The purpose of this utility model is to provide a thermal grease coating fixture to solve the problem in the background art where the coating fixture directly places the device to be coated inside the placement frame when applying thermal grease, and the distance between the placement frame and the mesh is fixed. This means that it can only coat devices of matching thickness, and it is inconvenient to adjust the placement height when coating devices of different thicknesses, resulting in inconvenient coating or even no coating at all.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a thermal grease coating fixture, comprising a coating fixture body, the coating fixture body including a placement frame, a support frame mounted on the upper surface of the placement frame via a hinge, a mesh screen provided at the bottom inner end of the support frame, and a coating plate slidably mounted on one end of the support frame via a slider; the coating fixture body also includes:

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.

[0024] Please see Figures 1 to 6 This utility model provides a technical solution: a thermal grease coating fixture, including a coating fixture body 100, the coating fixture body 100 including a placement frame 101, a support frame 102 mounted on the upper surface of the placement frame 101 via a hinge, a mesh 103 provided at the bottom of the inner part of the support frame 102, and a coating plate 104 slidably mounted on one end of the inner part of the support frame 102 via a slider, and the coating fixture body 100 is also provided with:

[0025] The height adjustment mechanism includes a support placement component disposed inside the placement frame 101. The height adjustment component is disposed at the connection between the middle position inside the placement frame 101 and the lower surface of the support placement component. When the coating fixture body 100 applies thermal grease to devices of different thicknesses, the height adjustment mechanism can adjust the support placement plate 1011 to the height for coating treatment, so that the coating fixture body 100 can adjust the coating operation for devices of different thicknesses.

[0026] To facilitate coating of devices of different thicknesses using a support and placement assembly, in this embodiment, preferably, the support and placement assembly includes a support and placement plate 1011 disposed inside the placement frame 101. Limiting grooves 1017 are formed on both sides of the placement frame 101, and limiting sliders 1018 are provided on both sides of the support and placement plate 1011. The limiting sliders 1018 are slidably connected to the interior of the limiting grooves 1017, facilitating stable movement of the limiting sliders 1018 within the limiting grooves 1017 when the support and placement plate 1011 is adjusted to the placement height during the application of thermal grease. This allows the device to be placed on the surface of the support and placement plate 1011 and then placed in contact with the surface of the mesh 103 for coating.

[0027] To facilitate height adjustment of the support plate 1011 using a height adjustment assembly, suitable for coating devices of different thicknesses, in this embodiment, preferably, the height adjustment assembly includes a lead screw 1013 rotatably positioned at the center of the placement frame 101. An internal threaded groove 1016 is formed at the center of the lower surface of the placement frame 101.

A movable adjustment bracket 1012 is fixed to the lower surface of the support plate 1011 by screws, and the lead screw 1013... Matching the internal structure of the movable adjustment frame 1012, the lead screw 1013 drives the movable adjustment frame 1012 to move on the outer surface of the lead screw 1013 when rotating, thereby moving and adjusting the support placement plate 1011 to the support placement height. The internal thread of the internal thread groove 1016 has an external thread reinforcing cover 1015. The inner surface of the external thread reinforcing cover 1015 presses against the surface of the handwheel 1014. After the height is adjusted, the external thread reinforcing cover 1015 rotates inside the internal thread groove 1016 to fix the handwheel 1014, thereby fixing the support placement plate 1011 after adjustment for coating operation.

[0028] The convenient disassembly and assembly mechanism includes a closing installation component located at the connection between the edge of the mesh 103 and the lower surface of the support frame 102. The upper surface of the closing installation component is provided with locking components on both sides, and the side of the closing installation component is provided with a locking and fixing component at the connection between the side of the closing installation component and the support frame 102. The convenient disassembly and assembly mechanism allows the mesh 103 to be easily disassembled and cleaned during use.

[0029] To facilitate the disassembly and cleaning of the mesh 103 using the closed mounting assembly, in this embodiment, preferably, the closed mounting assembly includes a mounting groove 1031 formed on the lower surface of the support frame 102. A fixing frame 1032 is fixedly mounted on the edge of the mesh 103 by screws, and the fixing frame 1032 matches the internal structure of the mounting groove 1031. The fixing frame 1032 can be installed inside the mounting groove 1031, thereby installing and using the mesh 103, and conversely, facilitating disassembly and cleaning.

[0030] To facilitate the fastening and installation of the fixed frame 1032 and the mesh 103 onto the lower surface of the support frame 102 using a snap-fit ​​assembly, in this embodiment, preferably, the snap-fit ​​assembly includes a slot 1033 formed on the upper surface of the mounting groove 1031 inside the support frame 102. Both ends of the upper surface of the fixed frame 1032 are integrally provided with a snap-fit ​​plate 1034. The internal structure of the snap-fit ​​plate 1034 matches the internal structure of the slot 1033. The fixed frame 1032 is quickly snapped and installed by snapping the snap-fit ​​plate 1034 into the slot 1033, and conversely, it is convenient for disassembly and cleaning.

[0031] To facilitate the secure installation of the fixed frame 1032 and the mesh 103 by using a locking and fixing assembly, in this embodiment, preferably, the locking and fixing assembly includes locking bolts 1035 that are threaded and rotated on both sides of the support frame 102. The fixed frame 1032 has an internal threaded hole 1036 on its side, and the end of the locking bolt 1035 is connected to the internal thread of the internal threaded hole 1036. After the fixed frame 1032 is secured and installed, the locking bolt 1035 can be rotated to insert into the internal threaded hole 1036 to secure the fixed frame 1032 and the mesh 103, which is convenient for fixed installation and use. Conversely, it is convenient for loosening, disassembly, and cleaning.

[0032] The working principle and usage process of this utility model are as follows: When using this thermal grease coating fixture, the main body 100 of the coating fixture is stably placed in the position of use by directly contacting the placement surface of the placement frame 101. After the main body 100 of the coating fixture is stably placed, the device that needs to be coated with thermal grease is placed inside the placement frame 101 on the surface of the support placement plate 1011. The support frame 102 is closed and fixed on the surface of the placement frame 101. At this time, the surface of the mesh 103 contacts the surface of the device. A certain amount of thermal grease is introduced onto the surface of the mesh 103. The coating plate 104 is held and slid on the surface of the mesh 103 to coat the thermal grease.

[0033] Then, when the coating fixture body 100 is in use, the position of the support placement plate 1011 is adjusted according to the required coating thickness of the device. The placement frame 101 is lifted, and the handwheel 1014 is used to rotate the lead screw 1013. When the lead screw 1013 rotates, the movable adjustment frame 1012 moves on the outer surface of the lead screw 1013. As the movable adjustment frame 1012 moves, it drives the support placement plate 1011 to move. When the support placement plate 1011 moves, it drives the limiting slider 1018 to be limited and controlled inside the limiting groove 1017. The height is stably adjusted to the support placement height. After adjustment, the external threaded reinforcing cover 1015 is rotated inside the internal threaded groove 1016 to press and fix the handwheel 1014, thereby fixing the lead screw 1013 and the movable adjustment frame 1012. This facilitates the smooth coating treatment of the upper surface of the device in contact with the lower surface of the mesh 103 when the device is placed on the surface of the support placement plate 1011. This allows the coating fixture body 100 to adjust and perform coating operations on devices of different thicknesses, improving the convenience of adjusting the position of the coating fixture body 100 in the thermal grease coating treatment and the coating effect.

[0034] Finally, before using the coating fixture body 100, the fixing frame 1032 is engaged with the mounting slot 1031 by the clamping plate 1034 engaging with the inside of the clamping slot 1033, thereby closing the mesh 103 inside the bottom of the support frame 102. The locking bolt 1035 is then rotated to engage with the internal threaded hole 1036 to fix the fixing frame 1032 and the mesh 103 for coating treatment. The installation is convenient. After the coating fixture body 100 has applied thermal grease, the mesh 103 can be disassembled and cleaned in the reverse operation. The disassembly and cleaning are convenient, improving the convenience of disassembling and assembling the mesh 103 during the thermal grease application process.

[0035] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
