Description

Technical Field

[0001] This utility model relates to the field of coating device technology, specifically to a coating device for threaded grease. Background Technology

[0002] Thread grease applicators are commonly used on mechanical equipment, assemblies, or hardware connections to ensure good lubrication during operation, reduce friction and wear. Grease forms a protective film to prevent air and moisture from directly contacting the metal surface, thereby reducing the risk of rust, extending the service life of the equipment, and maintaining its normal operation. Under high load or high temperature environments, grease can reduce thread locking, facilitating subsequent maintenance and disassembly.

[0003] However, existing thread grease application devices often cannot fully apply grease to the threads during actual use, and can only operate from one direction. This limitation greatly restricts the improvement of work efficiency, resulting in the inefficient and incomplete application of grease, which may affect the progress of the entire related work process and increase unnecessary time and labor costs.

[0004] Patent document CN205056382U discloses a threaded oil application device, which "consists of an oil gun, an oil guide tube, a housing, and a gun head. The housing is a semi-open cylinder with an outer edge at the open end and a through hole at the center of the closed end. The gun head is a cylindrical nylon rod placed inside the housing, with a central oil channel at one end corresponding to the through hole at the closed end of the housing, and a cross-shaped oil hole communicating with the central oil channel. The central oil channel is threaded. The oil guide tube is a hollow cylindrical tube, with one end threaded to the central oil channel of the gun head and the other end threaded..." It is threadedly connected to a refueling nozzle. The device uses a cylindrical nozzle with an internal cross-shaped oil hole to inject oil into the female thread of the oil pipe; a spring-compressed housing prevents oil leakage during operation; and a rubber scraper ring ensures even oil application, thus achieving uniform application, oil saving, and high efficiency. However, the thread oil application devices in the aforementioned published literature mainly consider achieving uniform application and oil saving, but do not consider the comprehensive application of grease to the threads. Therefore, it is necessary to develop a thread grease application device. Utility Model Content

[0005] The purpose of this invention is to provide a device for applying thread grease, so as to solve the technical problem mentioned in the background art that it is inconvenient to apply grease to the threads.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a threaded grease application device, comprising a storage tank and a square frame. A gear pump is installed on the top of the storage tank, and a delivery pipe is connected to the output end of the gear pump. The square frame is connected to the gear pump through the delivery pipe. A cylinder is fixedly installed on the square frame. A flow divider is fixedly installed inside the cylinder, and one end of the delivery pipe is connected to the flow divider. Circular grooves are symmetrically arranged inside the cylinder. Spray heads are arrayed on the circular grooves. A connecting groove is provided on the circular grooves. A trough body is fixedly installed inside the cylinder, and one end of the trough body is connected to the flow divider. The connecting groove is connected to the trough body.

[0007] Preferably, the storage tank is equipped with casters at the bottom and a pusher is installed on the guide rod at the top of the storage tank.

[0008] Preferably, a handle is fixedly installed on the square frame, and the delivery pipe passes through the handle.

[0009] Preferably, a positioning plate is fixedly installed at the bottom of the square frame, and a connecting plate corresponding to the positioning plate is fixedly installed at the top of the storage tank.

[0010] Preferably, a connector is fixedly installed on the square frame, an arc-shaped groove is embedded inside the cylinder, an air supply groove is embedded inside the cylinder, one end of the air supply groove is connected to the connector, the other end of the air supply groove is connected to the arc-shaped groove, and cleaning holes are arranged in an array on the arc-shaped groove.

[0011] Preferably, a drive motor is fixedly installed on the square frame.

[0012] Preferably, a rotating rod is fixedly connected to the output end of the drive motor, and a brush is fixedly installed on the rotating rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model facilitates the application of thread grease by using an annular groove and a spray head to comprehensively coat the threads with grease, thereby improving work efficiency. The gear pump extracts and delivers the grease stored in the storage tank. The grease flows through the delivery pipe into the distribution groove, and then through the cooperation of the groove body and the connecting groove, it flows into the annular groove. The spray head then sprays the grease onto the surface of the threads, ensuring comprehensive coating and improving the working efficiency of the thread grease application device.

[0015] 2. This utility model uses an installed brush to facilitate the cleaning of impurities adsorbed on the surface of the threads by the thread grease application device. The drive motor drives the rotating rod to rotate, which in turn drives the brush to move, so that the brush comes into contact with the thread surface and can remove the adsorbed substances from the surface, thereby improving the practicality of the thread grease application device.

[0016] 3. This utility model improves the cleanliness of the threads by installing a cleaning hole. The connector is connected to an external air pump through a pipe. When the air pump works, it causes air pressure to flow. The air pressure flows into the air supply groove through the connector and then into the arc-shaped groove. The cleaning hole causes the air pressure to flow to the surface of the threads, thereby removing the adsorbed substances on the surface of the threads and effectively preventing residues from adsorbing on the surface of the threads.

[0023] The technical solutions of the present invention's screw pump embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see Figures 1 to 4A device for applying thread-locking grease includes a storage tank 1 and a square frame 7. A gear pump 4 is mounted on the top of the storage tank 1, and a delivery pipe 5 is connected to the output end of the gear pump 4. The square frame 7 is connected to the gear pump 4 via the delivery pipe 5. A cylinder 11 is fixedly mounted on the square frame 7. A flow divider 12 is fixedly mounted inside the cylinder 11, and one end of the delivery pipe 5 is connected to the flow divider 12. Annular grooves 14 are symmetrically arranged inside the cylinder 11. Spray heads 16 are arrayed on the annular grooves 14, and connecting grooves 15 are provided on the annular grooves 14. A trough body 13 is fixedly mounted inside the cylinder 11, and one end of the trough body 13... The device is connected to the distribution groove 12 and the connecting groove 15 is connected to the tank body 13. When applying grease to the threads using the thread grease applicator, the threads to be greased are inserted into the cylinder 11, and the gear pump 4 is activated to extract and transfer the grease stored in the storage tank 1. The grease flows into the distribution groove 12 through the delivery pipe 5, and then flows into the annular groove 14 through the cooperation of the tank body 13 and the connecting groove 15. The grease can be sprayed onto the surface of the threads through the spray head 16, which can spray grease onto the entire surface of the threads, thus improving work efficiency.

[0025] Please see Figure 1 The storage tank 1 is equipped with casters 2 at the bottom and pushers 3 on the top guide rod of the storage tank 1. Pushing pushers 3, in conjunction with the casters 2, will move the storage tank 1.

[0026] Please see Figure 1 A handle 6 is fixedly installed on the square frame 7, and the conveying pipe 5 passes through the handle 6. The handle 6 makes it easy to pick up and move the cylinder 11 so that the cylinder 11 is fitted onto the thread, which makes it easier to apply grease to the thread.

[0027] Please see Figure 1 A positioning plate 8 is fixedly installed at the bottom of the square frame 7, and a connecting plate 9 corresponding to the positioning plate 8 is fixedly installed at the top of the storage tank 1. Threaded holes are provided on the connecting plate 9. Screws are used to connect the positioning plate 8 and the threaded holes on the connecting plate 9, thereby fixing the position of the cylinder 11. This makes it easy for manual removal of the threads to apply grease. The position of the cylinder 11 can be fixed or removed for use depending on the usage.

[0028] Please see Figure 2 and Figure 4A connector 10 is fixedly installed on the square frame 7. An arc-shaped groove 18 is embedded inside the cylinder 11. An air supply groove 17 is embedded inside the cylinder 11. One end of the air supply groove 17 is connected to the connector 10, and the other end of the air supply groove 17 is connected to the arc-shaped groove 18. Cleaning holes 19 are arranged in an array on the arc-shaped groove 18. The connector 10 is connected to an external air pump through a pipe. When the air pump works, it causes air pressure to flow. After the air pressure flows into the air supply groove 17 through the connector 10, it will flow into the arc-shaped groove 18. Through the cleaning holes 19, the air pressure will flow to the surface of the thread, thereby removing the adsorbed substances on the surface of the thread.

[0029] Please see Figure 1 and Figure 5 A drive motor 20 is fixedly installed on the square frame 7. A rotating rod 21 is fixedly connected to the output end of the drive motor 20. A brush 22 is fixedly installed on the rotating rod 21. When it is necessary to remove the adsorbed material on the surface of the thread, the drive motor 20 will drive the rotating rod 21 to rotate. When the rotating rod 21 rotates, it will drive the brush 22 to move, so that the brush 22 contacts the surface of the thread, thereby removing the adsorbed material from the surface of the thread, improving the cleaning efficiency, and avoiding the adsorption of impurities on the thread, which would affect the quality of the grease application.

[0030] Working principle: First, when applying grease to the threads using the thread lubricating device, the drive motor 20 rotates the rotating rod 21. The rotation of the rotating rod 21 causes the brush 22 to move, bringing it into contact with the thread surface and removing the adsorbed material. Then, the thread to be lubricated is manually removed and inserted into the cylinder 11. After manually aligning the thread with the center of the cylinder 11, the connector 10 is connected to an external air pump via a pipe. The air pump operates, causing air pressure to flow through the connector 10. After entering the air supply groove 17, the air pressure flows into the arc-shaped groove 18. Through the cleaning hole 19, the air pressure flows to the thread surface, thereby removing the adsorbed substances on the thread surface. The gear pump 4 works to extract and transfer the grease stored in the storage tank 1. The grease flows into the distribution groove 12 through the delivery pipe 5. Through the cooperation of the groove body 13 and the connecting groove 15, the grease flows into the annular groove 14. The grease can be sprayed onto the thread surface through the spray head 16, which can spray the grease onto the thread surface comprehensively, improving work efficiency.
