Description

Technical Field

[0001] This utility model relates to the field of engineering machinery technology, specifically to a hydraulic component connector for engineering machinery. Background Technology

[0002] Construction machinery is an important part of the equipment manufacturing industry. In general terms, construction machinery refers to the mechanical equipment necessary for comprehensive mechanized construction projects, including earthwork construction, road construction and maintenance, mobile lifting and loading operations, and various building projects. It is mainly used in national defense construction projects, transportation construction, energy industry construction and production, raw material industry construction and production such as mining, agriculture, forestry and water conservancy construction, industrial and civil buildings, urban construction, environmental protection and other fields. However, new types of joints are frequently used in the hydraulic components of construction machinery currently in use.

[0003] In the prior art, Chinese utility model with announcement number CN221034441U discloses a hydraulic component connector for engineering machinery, including a connector pipe, a fixed plate fixedly connected to the outside of the connector pipe, a connecting cylinder provided on the top of the fixed plate, a first bolt connecting the connecting cylinder and the fixed plate, a connecting plate fixedly connected to the top of the connecting cylinder, and multiple clamping blocks arranged at equal angles around the axis of the connecting cylinder inside the connecting cylinder, and guide columns fixedly connected to the outside of the clamping blocks.

[0004] In the aforementioned technology, rotating the knob causes the screw to rotate, which in turn moves the screw outward. The screw then moves the clamping block outward, causing the fixing block to loosen the connected pipe. This allows for quick disassembly of the entire connector. However, during fixing, the clamping block alone clamps and fixes the connected pipe. Therefore, when the connected pipe encounters high-frequency vibration and impact, relying on only one fixing point may lead to loosening or even detachment of the joint.

[0005] In view of this, the present invention solves the above-mentioned technical problems by proposing a hydraulic component connector for engineering machinery. Utility Model Content

[0006] To address the shortcomings of the aforementioned background technology, this utility model provides a technical solution for a hydraulic component connector for engineering machinery. By pulling a spring, the insertion rod is inserted into the mounting block, and then connected to the mounting block by a second bolt, thereby fixing the insertion rod. Since the spring is in a stretched state at this time, the connection between the connector pipe and the connecting pipe can be made tighter, avoiding the risk of loosening or even falling off due to shaking, thus solving the problems mentioned in the background technology.

[0007] This utility model provides the following technical solution: a hydraulic component connector for engineering machinery, comprising: a connector pipe and a connecting pipe;

[0008] The outer wall of the connecting pipe is provided with two clamping arc plates. Connecting blocks are fixed on both sides of the clamping arc plates respectively. A first bolt is threaded between the connecting blocks. A spring is fixed at the bottom of the clamping arc plates. An insertion rod is fixed at the bottom end of the spring. A positioning hole is opened on the outer wall of the insertion rod. Two mounting blocks are fixed at the top of the joint pipe. A second bolt is threaded inside the mounting block and passes through the positioning hole.

[0009] As a preferred embodiment of this utility model, a limiting rod is slidably installed inside the clamping arc plate, and the spring is sleeved on the outer wall of the limiting rod.

[0010] As a preferred embodiment of this utility model, two upper connecting blocks are fixed to the outer wall of the connecting pipe, two lower connecting blocks are fixed to the top of the joint pipe, and an insertion block is fixed to the bottom of the upper connecting blocks.

[0011] As a preferred embodiment of this utility model, an adjustment frame is fixed to one side of the lower connecting block. Two lead screws are rotatably installed inside the adjustment frame. A movable plate is threadedly connected to the outer wall of the lead screw. A first bevel gear is fixed to one end of the lead screw. A rotating rod is rotatably installed on one side of the adjustment frame. A second bevel gear is fixed to one end of the rotating rod. The second bevel gear meshes with the first bevel gear. A connecting hole is opened on one side of the adjustment frame. Two fixing rods are provided on one side of the adjustment frame. One end of the fixing rod is fixedly connected to one side of the movable plate.

[0012] As a preferred embodiment of this utility model, the inner wall of the clamping arc plate is fixed with an anti-slip pad.

[0013] As a preferred embodiment of this utility model, a protective cover is provided on the top of the connector pipe, and two nuts are rotatably installed on the outer wall of the connector pipe. A third bolt is connected to the internal thread of the nuts, and the top of the third bolt is fixedly connected to the bottom of the protective cover.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. In this utility model, the connector pipe and the connecting pipe are first connected and fixed. Then, the two clamping arc plates are fixed to the outer wall of the connecting pipe by the first bolt. At this time, the spring is pulled to allow the insertion rod to enter the mounting block. Then, the second bolt is threaded into the mounting block, thereby fixing the insertion rod. Therefore, the spring is in a stretched state at this time, which makes the connection between the connector pipe and the connecting pipe tighter, avoiding the risk of loosening or even falling off due to shaking, improving the stability after connection, and helping to complete the work smoothly after connection. When the spring is stretched, the limiting rod can limit the spring to avoid skewing, thereby improving the stability during stretching.

[0016] 2. In this utility model, by inserting the connecting pipe into the inside of the connector pipe, the insertion block is driven into the inside of the lower connecting block. Then, by rotating the rotating rod, the second bevel gear is rotated, which in turn causes the first bevel gear to rotate, thus driving the lead screw to rotate. This allows the moving plate to move left and right, thereby driving the fixing rod into the insertion block. Therefore, quick and secure installation can be achieved, which also facilitates subsequent disassembly and improves the efficiency of installation and disassembly. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1,

[0025] Please see Figure 1-4 As shown, a hydraulic component connector for engineering machinery includes: a connector pipe 1 and a connecting pipe 2;

[0026] Two clamping arc plates 3 are provided on the outer wall of the connecting pipe 2. Connecting blocks 4 are fixed on both sides of the clamping arc plates 3 respectively. A first bolt 5 is threaded between the connecting blocks 4. A spring 6 is fixed at the bottom of the clamping arc plates 3. An insertion rod 7 is fixed at the bottom end of the spring 6. A positioning hole 8 is opened on the outer wall of the insertion rod 7. Two mounting blocks 9 are fixed at the top of the joint pipe 1. A second bolt 10 is threaded inside the mounting block 9 and passes through the positioning hole 8.

[0027] A limit rod 11 is slidably installed inside the clamping arc plate 3, and a spring 6 is sleeved on the outer wall of the limit rod 11.

[0028] Two upper connecting blocks 12 are fixed to the outer wall of the connecting pipe 2, two lower connecting blocks 13 are fixed to the top of the joint pipe 1, and an insertion block 14 is fixed to the bottom of the upper connecting blocks 12.

[0029] An adjusting frame 15 is fixed to one side of the lower connecting block 13. Two lead screws 16 are rotatably installed inside the adjusting frame 15. A moving plate 17 is threadedly connected to the outer wall of the lead screw 16. A first bevel gear 18 is fixed to one end of the lead screw 16. A rotating rod 19 is rotatably installed on one side of the adjusting frame 15. A second bevel gear 20 is fixed to one end of the rotating rod 19. The second bevel gear 20 meshes with the first bevel gear 18. A connecting hole 21 is opened on one side of the adjusting frame 15. Two fixing rods 22 are provided on one side of the adjusting frame 15. One end of the fixing rod 22 is fixedly connected to one side of the moving plate 17.

[0030] In use, the connector pipe 1 and the connecting pipe 2 are first connected and fixed. Then, the two clamping arc plates 3 are fixed to the outer wall of the connecting pipe 2 by the first bolt 5. At this time, the spring 6 is pulled to allow the insertion rod 7 to enter the mounting block 9. Then, the second bolt 10 is threaded into the mounting block 9, thereby fixing the insertion rod 7. Therefore, the spring 6 is in a stretched state, which makes the connection between the connector pipe 1 and the connecting pipe 2 tighter, avoiding the risk of loosening or even falling off due to shaking, improving the stability after connection, and helping to complete the work smoothly after connection. When the spring 6 is stretched, the limiting rod 11 can limit the spring 6 to avoid skewing, thereby improving the stability during stretching.

[0031] By inserting the connecting pipe 2 into the joint pipe 1, the insertion block 14 is driven into the lower connecting block 13. Then, by rotating the rotating rod 19, the second bevel gear 20 is rotated, which in turn causes the first bevel gear 18 to rotate, thus driving the lead screw 16 to rotate. This allows the moving plate 17 to move left and right, thereby driving the fixing rod 22 into the insertion block 14. This enables quick and secure installation, and also facilitates subsequent disassembly, improving the efficiency of installation and disassembly.

[0032] Example 2,

[0033] For one specific embodiment of this utility model, please refer to Figure 1-5 As shown, the inner wall of the clamping arc plate 3 is fixed with an anti-slip pad 23; the top of the connector pipe 1 is provided with a protective cover 24, and two nuts 25 are rotatably installed on the outer wall of the connector pipe 1. The internal threads of the nuts 25 are connected to a third bolt 26, and the top of the third bolt 26 is fixedly connected to the bottom of the protective cover 24.

[0034] During use, the anti-slip pad 23 increases friction, which helps to make the clamping arc plate 3 more secure and stable when fixed, and also avoids wear on the outer wall of the connecting pipe 2; the protective cover 24 can be installed through the threaded connection of the third bolt 26 and the nut 25, which can protect the connection part during operation and prevent stones and other objects from impacting the connection part.
