Description

Technical Field

[0001] This utility model relates to the technical field of grease filling devices, and more specifically, to an injection-type lubrication device for composite sliding bearings. Background Technology

[0002] When using composite sliding bearings, lubricant is usually added periodically to ensure stable operation and reduce mechanical wear. When adding lubricant, injection lubrication equipment is generally used. The existing injection lubrication equipment is generally a grease gun. When in use, the lubricant is forced out from the reservoir or grease tank by using pressure difference and injected into the friction surface of the composite sliding bearing through pipes and components such as the grease gun.

[0003] A search revealed an existing technology that discloses an electric grease dispenser, patent publication number CN221825128U. In its use, "the motor, speed change mechanism, and rotary-to-linear motion mechanism are all integrated on the drive unit mounting section on one side of the plunger pump body. Furthermore, the motor and speed change mechanism are arranged parallel to the direction of plunger rod movement, with the motor located on the side of the speed change mechanism closer to the pump body, and the rotary-to-linear motion mechanism located below the speed change mechanism. This makes the entire electric grease dispenser's structure more compact, offering advantages such as small size, attractive appearance, and a superior user experience."

[0004] However, in actual use, the grease fitting head and the pipeline are generally connected by threads. When replacing the grease fitting head according to different installation environments, the grease fitting head is usually unscrewed. If the metal parts expand due to temperature changes or other reasons, the engagement between the threads will be tighter, requiring greater resistance to overcome during disassembly. Therefore, tools such as wrenches are needed to assist. Furthermore, during installation, the threads of the grease fitting head and the threads of the pipeline must be precisely aligned. Otherwise, misalignment or skewness of the threads may occur, making it difficult to tighten smoothly or resulting in an unstable installation. This makes replacing the grease fitting head inconvenient and affects the efficiency of use. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an injection-type lubrication device for composite sliding bearings, so as to solve the problem that in the prior art, the oil injection head adopts a threaded connection, which makes it inconvenient to replace the oil injection head when the threads are tightly engaged, thus resulting in low efficiency.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an injection lubrication device for composite sliding bearings, comprising a body and an oil injection head, wherein the body is connected to a handle via a pipe, the oil injection head is slidably connected to the left side of the handle, the oil injection head has multiple slots inside, a limit rod is slidably connected inside the slot, the other end of the limit rod is fixedly connected to the inside of the handle, two locking slots are opened inside the slots, locking blocks are locked inside the locking slots, and the locking blocks are slidably connected inside the limit rods.

[0007] The limiting rod has a placement groove on its inner right side and two mounting grooves on its inner left side. Mounting pieces are fixedly connected to the adjacent sides of the two locking blocks. A pull rope is fixedly connected to the other end of the mounting piece. An elastic element is sleeved on the outside of the pull rope. A retaining ring is fixedly connected to the end of the pull rope away from the mounting piece.

[0008] The grip has a limiting groove inside, a limiting ring is slidably connected inside the limiting groove, the right side of the limiting ring is in contact with the left side of the retaining ring, and an elastic element is sleeved on the outside of the limiting rod.

[0010] The locking block is slidably connected inside the mounting groove, the mounting plate is slidably connected inside the mounting groove, and the other side of the pull rope is slidably connected inside the limiting rod.

[0011] One end of the elastic element is fixedly connected to the inner wall of the mounting groove, and the other end of the elastic element is fixedly connected to the mounting plate. The retaining ring is slidably connected inside the placement groove.

[0012] The limiting ring is slidably connected to the outside of the limiting rod, one end of the second elastic element is fixedly connected to the inner wall of the limiting groove, and the other end of the second elastic element is fixedly connected to the limiting ring.

[0013] The inner protrusion of the pull ring is slidably connected to the inside of the groove, and the inner wall of the pull ring is slidably connected to the outside of the handle.

[0024] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0025] Example 1: Please refer to Figures 1 to 6 This utility model provides a technical solution: an injection lubrication device for composite sliding bearings, including a body 1 and an oil injection head 3. The body 1 is connected to a handle 2 via a pipe. The oil injection head 3 is slidably connected to the left side of the handle 2, so that the lubricant stored inside the body 1 can be injected into the composite sliding bearing through the oil injection head 3. The oil injection head 3 has multiple slots 7 inside, and a limit rod 6 is slidably connected inside the slots 7. The other end of the limit rod 6 is fixedly connected to the inside of the handle 2, so that the handle 2 and the oil injection head 3 will not rotate relative to each other. The slots 7 have two locking grooves 4 inside, and locking blocks 5 are locked inside the locking grooves 4. The locking blocks 5 are slidably connected to the inside of the limit rod 6, so that the oil injection head 3 can be locked onto the handle 2.

[0026] When the grease filler head 3 needs to be installed, the grease filler head 3 is slid against the handle 2, allowing the limiting rod 6 to slide into the corresponding slot 7. This moves the locking block 5 outward, allowing it to engage with the inside of the slot 4, thus ensuring the grease filler head 3 is stably installed on the handle 2. Conversely, it can be disassembled without the need for special tools, greatly saving installation time and effort. This results in high efficiency in replacing the grease filler head, leading to high usage efficiency and not affecting the maintenance time of the composite sliding bearing, thus making it highly economical to use.

[0027] Example 2: Based on Example 1, to facilitate the pulling of the locking block 5, a placement groove 13 is provided on the right side of the inner side of the limiting rod 6, and two mounting grooves 8 are provided on the left side of the inner side of the limiting rod 6. The locking block 5 is slidably connected to the inside of the mounting groove 8, allowing the locking block 5 to slide into the inside of the mounting groove 8. Mounting pieces 9 are fixedly connected to the adjacent sides of the two locking blocks 5. The mounting pieces 9 are slidably connected to the inside of the mounting groove 8, and the mounting groove 8 limits the mounting pieces 9, preventing them from shifting during sliding. A pull rope 11 is fixedly connected to the other end of the mounting pieces 9. The other side of the pull rope 11 is slidably connected to the inside of the limiting rod 6. The limiting rod 6 limits the pull rope 11, making it difficult for the pull rope 11 to deviate when sliding. An elastic element 10 is sleeved on the outside of the pull rope 11. A retaining ring 12 is fixedly connected to the end of the pull rope 11 away from the mounting plate 9. The retaining ring 12 is slidably connected to the inside of the placement groove 13. The placement groove 13 limits the retaining ring 12, allowing the retaining ring 12 to slide smoothly. One end of the elastic element 10 is fixedly connected to the inner wall of the mounting groove 8, and the other end of the elastic element 10 is fixedly connected to the mounting plate 9.

[0028] When the locking block 5 needs to be pulled, the locking ring 12 is moved, which drives the pull rope 11 to move. The other side of the pull rope 11 pulls the mounting piece 9 inward, which in turn causes the mounting piece 9 to compress the elastic element 10 and deform, thus causing the locking block 5 to disengage from the inside of the slot 4. Conversely, by releasing the locking ring 12, the elastic element 10 is reset, which pushes the mounting piece 9 outward, allowing the mounting piece 9 to push the locking block 5 into the inside of the slot 4.

[0029] Example 3: Based on Example 2, in order to facilitate the pulling of the retaining ring 12, a limiting groove 16 is provided inside the handle 2. A limiting ring 15 is slidably connected inside the limiting groove 16. The limiting ring 15 is slidably connected to the outside of the limiting rod 6. The limiting rod 6 and the limiting groove 16 limit the limiting ring 15, allowing the limiting ring 15 to slide smoothly. The right side of the limiting ring 15 is in contact with the left side of the retaining ring 12, so that the limiting ring 15 can drive the retaining ring 12 to move when it moves. An elastic element 2 14 is sleeved on the outside of the limiting rod 6. One end of the elastic element 2 14 is fixedly connected to the inner wall of the limiting groove 16, and the other end of the elastic element 2 14 is fixedly connected to the limiting ring 15.

[0030] When it is necessary to move the retaining ring 12, the limiting ring 15 is moved to the right, so that the limiting ring 15 can squeeze the elastic element 14 at the corresponding position to deform and drive the retaining ring 12 to move to the right. When the limiting ring 15 is released, the elastic element 14 can perform a reset movement, thereby pushing the limiting ring 15 to reset.

[0031] Example 4: Based on Example 3, in order to facilitate the pulling of the limiting ring 15, a pull ring 17 is fixedly connected to the outside of the limiting ring 15. The pull ring 17 is used to pull the limiting ring 15 to move. Multiple sliding grooves 18 are opened on the outer side of the inner wall of the limiting groove 16. The inner protrusion of the pull ring 17 is slidably connected to the inside of the sliding groove 18. The inner wall of the pull ring 17 is slidably connected to the outside of the handle 2, so that the pull ring 17 can slide smoothly.

[0032] The working process of this utility model is as follows:

[0033] When the oil filler head 3 needs to be replaced, pull the pull ring 17 to the right. This pull ring 17 moves the limiting ring 15 to the right, causing the limiting ring 15 to compress the elastic element 14, causing it to deform. This pushes the retaining ring 12 to the right, which in turn moves the pull rope 11. The other side of the pull rope 11 pulls the mounting plate 9 inward, causing the mounting plate 9 to compress the elastic element 10, causing it to deform. This causes the retaining block 5 to disengage from the inside of the retaining groove 4. At this point, pull the oil filler head 3 to the left to disassemble it. Then slide the oil filler head 3 of the required model against the handle 2, and release the pull ring 17, causing the elastic element... The second elastic element 14 is no longer restricted, thus allowing it to reset and push the limiting ring 15 to reset. At this time, the limiting ring 15 no longer pulls the retaining ring 12, allowing the first elastic element 10 to reset and push the mounting piece 9 to move outward. This allows the mounting piece 9 to push the retaining block 5 to engage with the inside of the retaining groove 4, making it easy to replace the oil filling head 3 without the need for special tools. This greatly saves installation time and effort, resulting in higher efficiency in replacing the oil filling head and thus higher usage efficiency. This does not affect the maintenance time of the composite sliding bearing, making it more economical to use.
