Description
Technical Field
[0001] This utility model relates to the technical field of compressor oil adding auxiliary devices, and in particular to a compressor oil adding auxiliary device. Background Technology
[0002] CNG compressors require regular oil filling. Due to limitations in the original design layout of the compressor and oil tank, oil filling currently requires pouring the oil from the oil tank into a small bucket, which is then manually carried up to the equipment for filling (the design layout limitations mean there is no dedicated ladder for climbing). This process wastes time and manpower, and there is a risk of slipping and falling during the climb, posing a significant safety hazard and failing to comply with relevant safety regulations.
[0003] Due to the special operating environment of CNG compressors and their high safety requirements, manual pumps are often used to add oil to CNG compressors in order to allow for direct oil addition at low levels and improve safety during refueling. However, manual pumps used for adding oil to CNG compressors generally lack a fixed connection point to the oil tank. Therefore, during use, it is usually necessary to manually support and fix the connection point of the manual pump to the oil tank, which is quite inconvenient in actual use.
[0004] Therefore, a compressor oil adding auxiliary device is proposed to solve the above-mentioned technical problems. Utility Model Content
[0005] To address the technical problems mentioned above, this utility model provides an auxiliary device for adding compressor oil.
[0006] This utility model is achieved using the following technical solution: a compressor oil adding auxiliary device, comprising a housing and a fixing mechanism:
[0007] The housing has a cylindrical cavity inside, and a conveying connection port and an input connection port are connected vertically on the same side of the housing. The three are connected. An input pipe is fixedly connected to the bottom of the input connection port for drawing oil. A fixing mechanism is provided on the outer wall of the input pipe. A bend is fixedly connected to the top of the conveying connection port. A hose is connected to the top of the bend, and a tapered connector is connected to the other end of the hose.
[0008] The fixing mechanism includes a disc fixedly connected to the outer wall of the input pipe. The bottom end of the disc is provided with a limiting component and an adjusting component. The adjusting component drives the limiting component to adapt to the changes in connection ports of different diameters.
[0009] As a further improvement to the above solution, the limiting component includes several radial grooves circumferentially opened on the disk, all of which penetrate the disk. The number of radial grooves is at least three. Each of the radial grooves has a slider that is radially slidably connected to it. Each slider is fixedly connected to a spring two on its inner side as it slides radially along the disk, and the other side of each spring two is fixedly connected to the radial groove.
[0010] As a further improvement to the above scheme, several sliders are fixedly connected to clamps at their bottom ends. The outer side of the clamps is formed into a cone shape with the tip pointing downwards, and the inner side of the clamps is formed into a hollow cylinder. The outer side of the clamps is threaded, and the inner side of the clamps is grooved.
[0011] As a further improvement to the above solution, the adjusting component includes an annular groove on the outer wall of the disc, and a rotating ring is rotatably connected inside the groove. Several vertical through holes are circumferentially opened at the outer end of the rotating ring. Each of the through holes is vertically slidably connected to a sliding rod. Each of the inwardly bent ends of the sliding rods is fixedly connected to an internal threaded block. The inner wall of the internal threaded block is provided with a threaded groove that matches the outer wall of the clamping plate.
[0012] As a further improvement to the above solution, a rotating block is eccentrically connected inside the housing, and the outer tread of the rotating block is always in contact with the inner wall of the housing. It is located between the conveying connection port and the input connection port. A movable groove is opened in the middle of the rotating block, and horizontal grooves are opened at both ends of the movable groove. The movable groove and the two horizontal grooves form a movable cavity. An abutment is slidably connected inside the movable cavity. The abutment includes two movable plugs, and the outer ends of the two movable plugs extend to the outside of the movable groove and are slidably connected to the horizontal grooves. A spring is connected to the middle of the inner side of each of the two horizontal grooves.
[0013] As a further improvement to the above scheme, a gear 1 is fixedly connected to the outer wall of the housing through the central axis of the rotating block 1, and a gear 2 is meshed with one side of the gear 1. A connecting shaft is fixedly connected to the gear 2 on the same axis. The connecting shaft is rotatably connected to the outer wall of the housing, and a protective shell is rotatably connected to the outer wall of the connecting shaft. The protective shell is sleeved on the outside of the gear 1 and the connecting shaft.
[0014] As a further improvement to the above solution, a connecting rod is fixedly connected to the outer wall of the connecting shaft, and a rotating hole is opened on the connecting rod away from the connecting shaft. A rotating block two is rotatably connected in the rotating hole, and a gripping rod is coaxially fixedly connected to the rotating block two on the side away from the housing.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] (I) This utility model utilizes a fixing mechanism to fix the oil drum, thereby solving the awkward situation of traditional manual pumps requiring one hand to fix the pump body and the other hand to drive it, making it more convenient to use. Furthermore, the fixing mechanism can also fix oil drums of different sizes, further improving the practicality of the device.
[0017] (ii) This utility model utilizes two elastically telescopic movable plugs, which can ensure the performance of the manual pump even when it is worn due to long-term use, thus indirectly improving its service life and reducing the frequency of maintenance. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0026] Example 1:
[0027] Please combine Figures 1-4 This embodiment of a compressor oil adding auxiliary device includes a housing 1 and a fixing mechanism:
[0028] The housing 1 has a cylindrical cavity inside, and on the same side of the housing 1, a conveying connection port 2 and an input connection port 3 are connected vertically in sequence, and the three are connected. The bottom end of the input connection port 3 is fixedly connected to an input pipe 18 for drawing oil. A fixing mechanism is provided on the outer wall of the input pipe 18. The top end of the conveying connection port 2 is fixedly connected to a bend 4, and the top end of the bend 4 is connected to a hose 5. The other end of the hose 5 is connected to a tapered connector 6. Specifically, the compressor oil filling port has been changed from the original nut-sealed port to a nut with a connecting pipe in the middle, and a rubber stopper is provided at the outer end of the connecting pipe. When oil needs to be added, the rubber stopper needs to be removed first, and the connector 6 needs to be inserted into it. Then, the input pipe 18 is inserted into the oil container, and the lever 17 is rotated to perform the oil filling operation.
[0029] The fixing mechanism includes a disc fixedly connected to the outer wall of the input pipe 18. The bottom end of the disc is provided with a limiting component and an adjusting component. The adjusting component drives the limiting component to adapt to the changes in connection ports of different diameters.
[0030] Inside the housing 1, there is an eccentrically rotatable rotating block 7, and the outer tread of the rotating block 7 is always in contact with the inner wall of the housing 1. It is located between the conveying connection port 2 and the input connection port 3. The rotating block 7 has a movable groove 8 in the middle, and both ends of the movable groove 8 have horizontal grooves 9. The movable groove 8 and the two horizontal grooves 9 form a movable cavity. A contact member is slidably connected inside the movable cavity. The contact member includes two movable plug plates 10, and the outer ends of the two movable plug plates 10 extend to the outside of the movable groove 8 and are slidably connected to the horizontal grooves 9. A spring 11 is connected to the middle of the inner side of each of the two horizontal grooves 9.
[0031] A gear 12 is fixedly connected to the outer wall of the housing 1 through the center axis of the rotating block 7. A gear 13 is meshed with one side of the gear 12. A connecting shaft 14 is fixedly connected to the gear 13 on the same axis. The connecting shaft 14 is rotatably connected to the outer wall of the housing 1. A protective shell 26 is rotatably connected to the outer wall of the connecting shaft 14. The protective shell 26 is sleeved on the outside of the gear 12 and the connecting shaft 14.
[0032] A connecting rod 15 is fixedly connected to the outer wall of the connecting shaft 14. A rotating hole is opened on the connecting rod 15 away from the connecting shaft 14. A rotating block 16 is rotatably connected in the rotating hole. A handle 17 is coaxially fixedly connected to the rotating block 16 on the side away from the housing 1.
[0033] The implementation principle of a compressor oil adding auxiliary device in this application embodiment is as follows:
[0034] After the connector 6 is installed, the input pipe 18 is installed in the oil drum using the fixing mechanism. Then, according to the rotation direction indicated by the device, hold the handle 17 and rotate it in the same direction. Under the meshing connection of gear 2 13 and gear 12, the internal rotating block 7 can rotate counterclockwise. As the rotating block 7 rotates, the spring 11 elastically connected in the two movable plug plates 10 will always push the movable plug plates 10 on both sides to slide outward and always abut against the inner wall of the cavity of the housing 1. Thus, the oil from the input pipe 18 can be injected into the compressor through the delivery connection port 2 from the connector 6.
[0035] Example 2:
[0036] Combination Figure 1 and Figure 5 This embodiment is an improvement on embodiment 1, further described in the following aspects:
[0037] The limiting component includes several radial grooves 19 circumferentially opened on the disk. The radial grooves 19 are all arranged through the disk. There are at least three radial grooves 19. A slider 20 is radially slidably connected in each of the radial grooves 19. A spring 21 is fixedly connected to the inner side of each slider 20 along the radial sliding of the disk. The other side of the spring 21 is fixedly connected to the radial groove 19.
[0038] Several sliders 20 are fixedly connected to a clamping plate 22 at their bottom ends. The clamping plates 22 together form a cone shape with the tip pointing downwards on the outer side and a hollow cylinder shape on the inner side. The outer side of the clamping plates 22 is threaded and the inner side of the clamping plates 22 is grooved.
[0039] The adjusting component includes an annular groove on the outer wall of the disc, and a rotating ring 23 is rotatably connected inside the groove. Several vertical through holes are circumferentially opened at the outer end of the rotating ring 23. Sliding rods 24 are vertically slidably connected inside the several through holes. Internal threaded blocks 25 are fixedly connected at the inward bends at the bottom ends of the several sliding rods 24. The inner wall of the internal threaded block 25 is provided with a threaded groove matching the outer wall of the clamping plate 22.
[0040] The implementation principle of this embodiment is as follows:
[0041] After the connector 6 is installed, insert the bottom end of the input pipe 18 into the open oil can, and put the several clamps 22 at the bottom end onto the cap opening. Then fix the housing 1 and rotate the rotating ring 23 so that the rotating ring 23 drives the internal thread block 25 at the bottom end to be threadedly connected to the clamp 22. As the two are threadedly connected and rotated, the slide rod 24 and the internal thread block 25 move vertically upward and push the several clamps 22 to slide inward synchronously. Finally, they are fixed at the oil can can be driven by the inner wall of the clamps 22 and the opening of the oil can. At this time, the manual pump can be driven quickly.
[0042] When adding engine oil, make sure to handle the oil properly to prevent leakage; to release the lock, simply reverse the above steps.
