The combined use of the first threaded sleeve, the second threaded sleeve, the third threaded sleeve, and the two connecting pipes significantly improves the impact resistance of the device.

Description

Technical Field

[0001] This utility model relates to the field of oil pump connectors, and more specifically, to an oil pump protective connector. Background Technology

[0002] In modern mechanical equipment, oil pumps are one of the key components for power transmission and are widely used in hydraulic systems, lubrication systems and other fields. The normal operation of oil pumps directly affects the working efficiency and service life of equipment. Therefore, the protection and maintenance of oil pumps are particularly important.

[0003] A search revealed that Chinese Patent Publication No. CN212302315U discloses "a protective connector for an injection pump, comprising a protective connector body, clamps, a rubber sealing sleeve, and an adjusting bolt. One end of the protective connector body is provided with an oil inlet, and one end of the oil inlet is connected to an oil delivery pipe. The two ends of the rubber sealing sleeve are respectively fitted onto the oil delivery pipe and the protective connector body, and the rubber sealing sleeve covers the oil inlet. Two clamps are provided, and the two clamps press the rubber sealing sleeve tightly onto the oil delivery pipe and the protective connector body. This utility model, by having the two ends of the rubber sealing sleeve respectively fitted onto the oil delivery pipe and the protective connector body, and the rubber sealing sleeve covering the oil inlet, and the two clamps pressing the rubber sealing sleeve tightly onto the oil delivery pipe and the protective connector body, not only ensures a stable and tight connection between the oil delivery pipe and the protective connector body, making it safe and reliable to use, but also plays a role in preventing oil leakage, achieving secondary protection and improving the practicality of the protective connector." However, the following defects still exist:

[0004] The device connects the protective joint body and the oil pipeline using two clamps. These clamps are prone to loosening under high-frequency vibration or external impact, especially in complex working environments, potentially leading to an unstable connection between the oil pump and the oil pipeline, increasing safety hazards. Therefore, an oil pump protective joint is proposed. Utility Model Content

[0005] The purpose of this utility model is to address the problem that existing oil pump protective joints connect the protective joint body and the oil pipeline using two clamps. These clamps are prone to loosening under high-frequency vibration or external impact, especially in complex working environments, which may lead to an unstable connection between the oil pump and the oil pipeline and increase safety hazards. This utility model provides an oil pump protective joint to solve the problems mentioned in the background art.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0007] The present invention is as follows: an oil pump protective connector, including an oil inlet pipe and an oil outlet pipe, wherein a connecting mechanism for connecting the oil inlet pipe and the oil outlet pipe is provided on one side of the oil inlet pipe and the oil outlet pipe, and a secondary protective component is provided on the outside of the connecting mechanism;

[0008] The connecting mechanism includes springs fixedly connected inside the oil inlet pipe and the oil outlet pipe. One end of each of the two springs is fixedly connected to a first stop ball and a second stop ball, respectively. One end of each of the oil inlet pipe and the oil outlet pipe is fixedly connected to a connecting pipe. A connecting pipe is fixedly connected to the outer wall of the second stop ball. Both ends of the connecting pipe are provided with several oil inlet holes.

[0009] As a preferred technical solution of this utility model, the secondary protection component includes a first threaded sleeve and a second threaded sleeve respectively threadedly connected to one end of the oil inlet pipe and the oil outlet pipe, and a third threaded sleeve rotatably connected to the outer wall of the first threaded sleeve, the third threaded sleeve being threadedly connected to the second threaded sleeve.

[0010] As a preferred technical solution of this utility model, a blocking ring is fixedly connected to the outside of the connecting pipe, the opposite side walls of the blocking ring are tightly fitted with one end of the two connecting pipes, and the periphery of the blocking ring is tightly fitted with the inner wall of the first threaded sleeve and the second threaded sleeve.

[0011] As a preferred technical solution of this utility model, a guide tube for facilitating oil discharge is fixedly connected to the inner wall of the oil inlet pipe, and one end of the guide tube is tightly fitted to the side wall of the connecting pipe.

[0012] As a preferred technical solution of this utility model, a plurality of observation holes are provided on the outer wall of the first threaded sleeve, and a transparent glass plate is fixedly connected inside each of the plurality of observation holes.

[0013] As a preferred technical solution of this utility model, a limiting ring is fixedly connected to the outer wall of the connecting pipe, and a limiting groove is opened inside the communicating pipe, with the limiting ring and the limiting groove being slidably connected.

[0014] As a preferred technical solution of this utility model, arc-shaped grooves are provided on the side walls of the two connecting pipes, and the first and second blocking balls are respectively tightly fitted to the inner walls of the two arc-shaped grooves.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. Through the set connection mechanism and secondary protection components, when in use, the oil inlet pipe and the oil outlet pipe are brought close to each other, and then the third threaded sleeve is rotated so that one end of the first threaded sleeve is in contact with one end of the second threaded sleeve. At this time, one end of the connecting pipe is in contact with the outer wall of the first plug ball. Then the first spring and the second spring will retract, thereby creating a distance between the first plug ball, the second plug ball and the two connecting pipes, so that the oil enters the oil inlet pipe through the oil inlet hole, and then enters the oil outlet pipe through the oil inlet pipe. Through the coordinated use of the first threaded sleeve, the second threaded sleeve, the third threaded sleeve and the two connecting pipes, the impact resistance of the device can be greatly improved, and loosening can be avoided.

[0017] 2. With the addition of a blocking ring, the blocking ring can block the gap between the two connecting pipes and the gap between the first threaded sleeve and the second threaded sleeve during use, effectively preventing oil leakage. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0026] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely to illustrate some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0027] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0028] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0029] like Figure 1 and Figure 2 As shown, this embodiment proposes an oil pump protection connector, including an oil inlet pipe 1 and an oil outlet pipe 2. A connecting mechanism 3 is provided on one side of the oil inlet pipe 1 and the oil outlet pipe 2 to connect the oil inlet pipe 1 and the oil outlet pipe 2. A secondary protection component 4 is provided outside the connecting mechanism 3. The oil inlet pipe 1 is connected to an external oil conveying equipment, and the oil outlet pipe 2 is connected to an external oil pump.

[0030] like Figure 4 As shown, the connecting mechanism 3 includes springs 301 fixedly connected inside the oil inlet pipe 1 and the oil outlet pipe 2. One end of each spring 301 is fixedly connected to a first plug ball 302 and a second plug ball 303. One end of each oil inlet pipe 1 and the oil outlet pipe 2 is fixedly connected to a connecting pipe 304. A connecting pipe 305 is fixedly connected to the outer wall of the second plug ball 303. When the springs 301 contract, the first plug ball 302 and the second plug ball 303 will enter the oil outlet pipe 2 through the connecting pipe 305. Both ends of the connecting pipe 305 are provided with several oil inlet holes 306. In use, the oil inlet pipe 1 and the oil outlet pipe 2 are brought close to each other. Then, one end of the connecting pipe 305 is pressed against the outer wall of the first plug ball 302. Then, the oil inlet pipe 1 or the oil outlet pipe 2 is moved. At this time, the two springs 301 will contract, and the oil will enter the oil inlet pipe 1, then enter the connecting pipe 305 through the oil inlet holes 306, and then enter the oil outlet pipe 2 and enter the external oil pump.

[0031] like Figure 5As shown, the secondary protection component 4 includes a first threaded sleeve 401 and a second threaded sleeve 402 respectively threadedly connected to one end of the oil inlet pipe 1 and the oil outlet pipe 2. A third threaded sleeve 403 is rotatably connected to the outer wall of the first threaded sleeve 401. The third threaded sleeve 403 is threadedly connected to the second threaded sleeve 402. When the connecting pipe 305 contacts the first plug ball 302, the third threaded sleeve 403 is rotated, thereby causing the second threaded sleeve 402 to drive the oil outlet pipe 2 to move until the first threaded sleeve 401 and the second threaded sleeve 402 fit together, which can quickly connect the oil inlet pipe 1 and the oil outlet pipe 2.

[0032] like Figure 4 As shown, a blocking ring 5 is fixedly connected to the outside of the connecting pipe 305. The two opposite side walls of the blocking ring 5 are tightly fitted to one end of the two connecting pipes 304. The periphery of the blocking ring 5 is tightly fitted to the inner wall of the first threaded sleeve 401 and the second threaded sleeve 402. The blocking ring 5 is made of corrosion-resistant rubber. When the first threaded sleeve 401 and the second threaded sleeve 402 are fitted together, the outer wall of the blocking ring 5 will fit with one end of the two connecting pipes 304, thereby improving the sealing between the two connecting pipes 304.

[0033] like Figure 4 As shown, a guide tube 6 is fixedly connected to the inner wall of the oil inlet pipe 1 to facilitate oil discharge. One end of the guide tube 6 is tightly fitted to the side wall of the connecting pipe 304. When in use, the guide tube 6 can reduce the impact force between the oil and the side wall of the oil discharge pipe 2 near the spring 301, thereby increasing the oil discharge speed.

[0034] like Figure 1 As shown, a number of observation holes 7 are provided on the outer wall of the first threaded sleeve 401. A transparent glass plate 8 is fixedly connected inside each of the observation holes 7. During use, the user can observe whether there is oil leakage inside the first threaded sleeve 401 and the second threaded sleeve 402 through the observation holes 7 and the transparent glass plate 8.

[0035] like Figure 6 As shown, a limiting ring 9 is fixedly connected to the outer wall of the connecting pipe 305, and a limiting groove 10 is opened inside the connecting pipe 304. The limiting ring 9 and the limiting groove 10 are slidably connected. When in use, the limiting groove 10 can prevent the limiting ring 9 from moving excessively, which would cause the spring 301 to be over-compressed and improve the service life of the spring 301.

[0036] like Figure 4 As shown, arc-shaped grooves 11 are provided on the side walls of the two connecting pipes 304. The first plug ball 302 and the second plug ball 303 are tightly fitted to the inner walls of the two arc-shaped grooves 11 respectively. When the two springs 301 drive the first plug ball 302 and the second plug ball 303 to reset respectively, they can increase the contact area between the first plug ball 302 and the second plug ball 303 and the connecting pipe 304, thereby improving the sealing performance.

[0037] Specifically, when using this oil pump protective connector: bring the inlet pipe 1 and the outlet pipe 2 close to each other, then place one end of the connecting pipe 305 against the outer wall of the first plug ball 302, and then continue to move the inlet pipe 1 or the outlet pipe 2. At this time, the two springs 301 will contract, and then rotate the third threaded sleeve 403, which will cause the second threaded sleeve 402 to move the outlet pipe 2 until the first threaded sleeve 401 and the second threaded sleeve 402 are in contact. At this time, the outer wall of the blocking ring 5 will be in contact with one end of the two connecting pipes 304, thereby improving the sealing between the two connecting pipes 304 and enabling quick connection of the inlet pipe 1 and the outlet pipe 2 (e.g., Figure 3 and Figure 4 As shown), oil is then injected through the oil inlet pipe 1 of the external oil injection equipment box. The oil enters the oil inlet pipe 1, then enters the connecting pipe 305 through the oil inlet hole 306, and then enters the oil outlet pipe 2, and finally enters the external oil pump. Through the combined use of the first threaded sleeve 401, the second threaded sleeve 402, the third threaded sleeve 403 and the two connecting pipes 304, the impact resistance of the device can be greatly improved (e.g., Figure 3 and Figure 4 (As shown).

[0038] All technical features in this embodiment can be freely combined according to actual needs.

[0039] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
