Description

Technical Field

[0001] The present invention relates to the technical field of hydraulic pumps, and in particular to a housing structure of a hydraulic pump. Background Art

[0002] The hydraulic pump is a key component in the hydraulic system, and its casing structure is an important part that supports and accommodates the internal parts of the pump.

[0003] The hydraulic pump is equipped with inlet and outlet pipes. The hydraulic pump will vibrate when it is running. This vibration will cause the pipes connected to the hydraulic pump to loosen. First of all, loose connections may lead to serious leakage problems. Both hydraulic oil and water may seep out or spray out from the loose connections, which will not only cause waste of resources, but also pollute the environment. Especially when dealing with harmful or corrosive fluids, the leakage problem is more serious. Secondly, loose connections may also affect the normal operation of the hydraulic system. The efficiency, stability and reliability of the hydraulic system depend on the close fit between the various components. If the pipeline connection is loose, it may cause poor fluid flow, unstable pressure or system failure, which will affect the operating efficiency and performance of the entire equipment. Summary of the invention

[0004] In order to overcome the above technical problems, an object of the present invention is to provide a housing structure of a hydraulic pump.

[0005] The purpose of the present invention can be achieved through the following technical solutions:

[0006] A housing structure of a hydraulic pump, comprising:

[0007] Pump housing;

[0008] A mounting pipe, fixed on the pump housing, the surface of the mounting pipe being provided with external threads;

[0009] A mounting ring, placed directly above the mounting tube;

[0010] Two connecting rods, one end of each of which is fixedly connected to the pump housing, and the other end of each of which is fixedly connected to the mounting ring;

[0011] A pressing structure, arranged on the mounting ring;

[0012] The control structure is arranged on the mounting tube.

[0013] As a further solution of the present invention: the compression structure comprises:

[0014] Three openings are all provided on the mounting ring;

[0015] Three pressing rods are slidably disposed in the three openings respectively;

[0016] Three end caps are respectively fixed to one end of the three pressing rods;

[0017] Three springs, one end of each of which is connected to the mounting ring, and the other end of each of which is connected to the three end caps respectively;

[0018] The three pressing plates are respectively fixed on the other ends of the three pressing rods.

[0019] As a further solution of the present invention: the control structure includes:

[0020] A clamping ring is placed below the mounting ring, and the top opening of the clamping ring is larger than the bottom opening;

[0021] The moving cylinder has a thread groove on its inner ring and is threadably sleeved on the mounting tube.

[0022] As a further solution of the present invention: the inner surface of the opening and the outer surface of the pressing rod are in contact with each other.

[0023] As a further solution of the present invention: the three clamping plates are distributed in a circumferential array.

[0024] As a further solution of the present invention: the clamping plate has an arc-shaped structure, and the surface of the clamping plate is provided with anti-slip grooves.

[0025] Beneficial effects of the present invention:

[0026] Through the elastic force of three springs, the three clamping plates are closely close to the inner ring of the mounting ring in the initial state. When connecting the mounting tube and the pipeline, the pipeline passes through the mounting ring and is located between the three clamping plates. Then, by rotating the moving cylinder and utilizing the threaded connection between the moving cylinder and the mounting tube, the moving cylinder is moved on the mounting tube. The movement of the moving cylinder drives the clamping ring to rise. Due to the special design of the clamping ring, it squeezes the three end caps, thereby pushing the three clamping plates close to each other and clamping the pipeline together. This design not only ensures a tight connection between the pipeline and the mounting tube, but also effectively avoids the problem of loose pipeline caused by vibration of the hydraulic pump. In summary, the hydraulic pump housing structure significantly improves the stability and reliability of the pipeline connection through the clamping and fixing mechanism, reduces the risk of loose connection caused by vibration, and thus ensures the normal operation and safety of the hydraulic system.

[0028] Figure 1 It is a schematic diagram of the overall structure of the present invention;

[0029] Figure 2 yes Figure 1A magnified view of the structure at A.

[0030] In the figure: 1 pump body shell, 2 mounting pipe, 3 mounting ring, 4 connecting rod, 51 opening, 52 clamping rod, 53 end cap, 54 spring, 55 clamping plate, 61 clamping ring, 62 moving cylinder. DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] like Figure 1-2 As shown, a housing structure of a hydraulic pump includes a pump housing 1; a mounting pipe 2, which is fixed on the pump housing 1, and the surface of the mounting pipe 2 is provided with an external thread; a mounting ring 3, which is placed just above the mounting pipe 2; two connecting rods 4, one end of which is fixedly connected to the pump housing 1, and the other end of which is fixedly connected to the mounting ring 3;

[0033] The housing structure of the hydraulic pump also includes a clamping structure, which is arranged on the mounting ring 3. The clamping structure includes: three openings 51, all of which are opened on the mounting ring 3; three clamping rods 52, which are respectively slidably arranged in the three openings 51, and the inner surface of the opening 51 and the outer surface of the clamping rod 52 are mutually fitted; three end caps 53, which are respectively fixed to one end of the three clamping rods 52; three springs 54, one end of which is connected to the mounting ring 3, and the other end is respectively connected to the three end caps 53; three clamping plates 55, which are respectively fixed to the other end of the three clamping rods 52, and the three clamping plates 55 are distributed in a circumferential array, and the clamping plates 55 are in an arc structure, and the surface of the clamping plates 55 is provided with anti-slip grooves. When the three end caps 53 are squeezed, they can move synchronously and drive the three clamping plates 55 to move, so that the three clamping plates 55 are close to each other until the three clamping plates 55 press the pipeline together. At this time, the three clamping plates 55 can play a role in clamping and fixing the pipeline to prevent the pipeline from loosening due to the vibration of the hydraulic pump;

[0034] The housing structure of the hydraulic pump also includes a control structure, which is arranged on the mounting tube 2. The control structure includes: a clamping ring 61, which is placed below the mounting ring 3, and the top opening size of the clamping ring 61 is larger than the bottom opening size; a moving cylinder 62, the inner ring of which is provided with a threaded groove, and the moving cylinder 62 is threadedly sleeved on the mounting tube 2. The staff rotates the moving cylinder 62. Since the moving cylinder 62 is threadedly sleeved on the mounting tube 2, the moving cylinder 62 can move on the mounting tube 2 when it rotates, and the moving cylinder 62 can drive the clamping ring 61 to move upward when it moves. Since the top opening size of the clamping ring 61 is larger than the bottom opening size, the clamping ring 61 can squeeze the three end caps 53 when it moves upward.

[0035] Working principle of the present invention:

[0036] When the housing structure of the hydraulic pump proposed by the present invention is actually used, in the initial state, under the elastic force of the three springs 54, the three clamping plates 55 are all located close to the inner ring of the mounting ring 3. When connecting the mounting pipe 2 and the pipeline, the staff first passes the pipeline through the mounting ring 3, and then connects the mounting pipe 2 and the pipeline together. When the pipeline passes through the mounting ring 3, the pipeline will be located between the three clamping plates 55. Then, the staff rotates the moving cylinder 62. Since the moving cylinder 62 is threadedly sleeved on the mounting pipe 2, the moving cylinder 62 can be rotated on the mounting pipe 2. When the moving cylinder 62 moves, it can drive the clamping ring 61 to move upward. Since the top opening size of the clamping ring 61 is larger than the bottom opening size, the clamping ring 61 can squeeze the three end caps 53 when it moves upward. When the three end caps 53 are squeezed, they can move synchronously and drive the three clamping plates 55 to move, so that the three clamping plates 55 are close to each other until the three clamping plates 55 press the pipeline together. At this time, the three clamping plates 55 can clamp and fix the pipeline to prevent the pipeline from loosening due to the vibration of the hydraulic pump.

[0037] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
