Description

Technical Field

[0001] This utility model relates to the field of air compressor technology, and in particular to an anti-loosening air compressor inlet pipe fixing device. Background Technology

[0002] An air compressor is a fluid machine that elevates low-pressure gas to high-pressure gas. It is widely used in aerospace, automotive, energy, and other fields, and its operating efficiency and stability directly affect the performance of the entire power system. As a crucial component of the air compressor, the intake pipe is responsible for delivering external gas into the compressor's interior; therefore, the stability of its connection is paramount.

[0003] During the operation of an air compressor, continuous vibration is generated, necessitating the fixation of the intake pipe. However, traditional fixing devices using a single bolt or clip structure are prone to gaps in the connecting parts due to prolonged vibration. This can cause the bolt to rotate or shift axially, resulting in relative wobbling between the intake pipe and the fixing device. This not only affects the smoothness of gas delivery and reduces intake efficiency but also leads to wear on the intake pipe due to continuous friction, potentially causing safety hazards such as air leaks. In severe cases, it can affect the normal operation of the air compressor, increasing equipment maintenance costs and the risk of failure. Therefore, we have introduced an anti-loosening air intake pipe fixing device for air compressors. Utility Model Content

[0004] The main purpose of this utility model is to provide a compressor inlet pipe fixing device to prevent loosening, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A compressor inlet pipe fixing device for preventing loosening includes a fixing plate, four fixing lugs are fixedly connected to the outer surface of the fixing plate, and the inner rear wall of each of the four fixing lugs is provided with a through fixing hole. A locking mechanism is inserted and installed at the upper end of the fixing plate, and a locking structure is fixedly connected to the front end of the fixing plate.

[0007] Preferably, the locking mechanism includes an adjustment structure, an upper clamping component is threadedly connected to the upper part of the outer surface of the adjustment structure, and a lower clamping component is threadedly connected to the lower part of the outer surface of the adjustment structure. The upper clamping component and the lower clamping component have the same structure and are distributed in a mirror image.

[0008] By adopting the above technical solution, the upper clamping component and the lower clamping component can move synchronously in opposite directions through the adjustment structure, which can quickly clamp or release the air inlet pipe, adapt to air inlet pipes of different diameters, and is easy to operate.

[0009] Preferably, the adjustment structure includes a movable rod, with a first anti-slip knob fixedly connected to the upper end of the movable rod, and a bidirectional screw fixedly connected to the lower end of the movable rod. The outer surface of the bidirectional screw has a first locking screw hole that passes through from front to back.

[0010] By adopting the above technical solution: the first anti-slip knob facilitates manual operation, the bidirectional screw can drive the upper clamping component and the lower clamping component to move synchronously, and the first locking screw hole, in conjunction with the locking structure, prevents loosening and improves the reliability of fixation.

[0011] Preferably, the upper clamping assembly includes a transmission block, a first connecting plate is fixedly connected to the right end of the transmission block, an arc-shaped clamping plate is fixedly connected to the right end of the first connecting plate, a second connecting plate is fixedly connected to the right side of the outer surface of the arc-shaped clamping plate, a guide hole with vertical through-hole is opened at the upper end of the second connecting plate, a rubber gasket is fixedly connected to the inner wall surface of the arc-shaped clamping plate, and the transmission block is threadedly connected to the outer surface of the bidirectional screw.

[0012] By adopting the above technical solution: the arc-shaped clamping plate fits the shape of the air intake pipe, the rubber gasket enhances friction and buffering to avoid wear on the air intake pipe, and the transmission block cooperates with the bidirectional screw to achieve stable movement.

[0013] Preferably, the fixing plate includes a plate body, the front end of which has a through mounting hole, the left front end of which is fixedly connected to a U-shaped plate with an opening facing left, the right inner wall of which has a through guide groove, and the right front end of which has two connecting blocks fixedly connected to the right side of the plate body, and a guide rod is fixedly connected between the two connecting blocks.

[0014] By adopting the above technical solution: the mounting hole provides space for the air intake pipe, and the U-shaped plate and guide rod provide guiding support for the movement of the clamping assembly, ensuring structural stability and improving overall rigidity.

[0015] Preferably, the lower end of the movable rod is movably connected to the upper end of the U-shaped plate via a bearing, and the lower end of the bidirectional screw is movably connected to the lower inner wall surface of the U-shaped plate via a rotating shaft.

[0016] By adopting the above technical solutions, the adjustment structure can rotate flexibly, friction can be reduced, the upper and lower clamping components can move smoothly, and the operating feel and structural durability can be improved.

[0017] Preferably, the left part of the first connecting plate is movably sleeved in the guide groove, the rear part of the arc-shaped clamping plate is movably sleeved in the mounting hole, and the second connecting plate is movably sleeved on the guide rod through the guide hole.

[0018] By adopting the above technical solution, the movement trajectory of the first connecting plate is limited to prevent deviation, ensuring the alignment of the two arc-shaped clamping plates and improving clamping stability.

[0019] Preferably, the locking structure includes a locking block and a locking screw. The front end of the locking block has a second locking screw hole, the front end of the locking screw is fixedly connected to a second anti-slip knob, and the rear end of the locking block is fixedly connected to the front end of the plate.

[0020] By adopting the above technical solution, the locking screw and the second anti-slip knob are easy to operate, and the locking block and the second locking screw hole cooperate to provide a fixing point for the locking screw, forming an anti-loosening foundation.

[0021] Preferably, the outer surface of the locking screw is threaded to the inner wall of the first locking screw hole and extends into the second locking screw hole.

[0022] By adopting the above technical solution, the bidirectional screw is rigidly connected to the locking block to prevent the bidirectional screw from rotating, forming a double locking, which completely solves the loosening problem and ensures long-term stability.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] In this invention, the first anti-slip knob of the adjusting structure in the rotary locking mechanism drives the movable rod and the bidirectional screw to rotate, causing the upper and lower clamping components to move away from each other along the bidirectional screw, facilitating the insertion of the compressor inlet pipe. After the inlet pipe is placed between the arc-shaped clamping plates and centered, the first anti-slip knob is rotated in the opposite direction, causing the bidirectional screw to drive the upper and lower clamping components closer together. During this process, the first connecting plate slides along the guide groove of the U-shaped plate, and the second connecting plate slides along the guide rod through the guide hole, ensuring... The arc-shaped clamping plate moves smoothly until the rubber pad tightly adheres to the outer surface of the intake pipe, achieving a firm clamping of the intake pipe. Finally, rotate the second anti-slip knob of the locking structure to allow the locking screw to pass through the first locking screw hole of the bidirectional screw and be threaded into the second locking screw hole of the locking block, thus completing the locking of the bidirectional screw. The entire device is not only easy to install and can adapt to intake pipes of different specifications, but also maintains a stable fixing effect for a long time, ensuring the normal operation of the compressor intake pipe and reducing failures and maintenance costs caused by loosening.

Rotate the second anti-slip knob 53 to drive the locking screw 52 to rotate, so that the locking screw 52 passes through the first locking screw hole 414 of the bidirectional screw 413 and is threaded into the second locking screw hole 54 of the locking block 51, completing the locking of the bidirectional screw 413 and preventing it from loosening during operation.
