Description

Technical Field

[0001] This invention belongs to the technical field of hydraulic oil pipe equipment, and specifically relates to a quick connection and locking device for hydraulic oil pipes. Background Technology

[0002] The hydraulic oil pipe quick connection locking device is used for connecting hydraulic oil pipes, thereby enabling rapid connection and transmission of pressurized oil. The hydraulic oil is guided and transmitted through the hydraulic oil pipes to the designated location for processing and production. However, current hydraulic hose quick-connect locking devices have the following problems: they are not convenient for reinforcement connections and are prone to connection instability. Summary of the Invention

[0003] The purpose of this invention is to provide a quick-connect locking device for hydraulic oil pipes.

[0004] A quick-connect locking device for hydraulic oil pipes includes a first locking structure and a second locking structure, wherein the side end of the first locking structure is fixedly connected to the second locking structure. The first connection locking structure includes a first protective shell, a first guide transmission seat is fixedly provided inside the first protective shell, a conduction hole is provided on the first guide transmission seat, a support is fixedly provided at the center side end of the first guide transmission seat, a first spring retraction rod is telescopically connected to the support, a first cone cap is fixedly connected to the side end of the first spring retraction rod, the side end of the first cone cap is fixedly connected to a first blocking block, and the side end of the first blocking block is fixedly connected to a mating extrusion rod. The second connection locking structure includes a second guide transmission seat, a second spring retraction rod is telescopically connected to the side end of the second guide transmission seat, the two ends of the second spring retraction rod are fixed to the second cone cap, the side end of the second cone cap is fixedly connected to the second blocking block, and the side end of the second blocking block is fixedly provided with a mating extrusion rod, and the mating extrusion rod and the second blocking block slide within the support collar.

[0005] Furthermore, the first connecting locking structure is used for the conduction of hydraulic oil. The mating extrusion rod, the first blocking block, and the first cone cap are elastically slidably connected in the first protective shell through the first spring contraction rod. When the first blocking block is pressed, there is a gap between it and the first protective shell. The hydraulic oil reaches the first cone cap through the gap and is guided to the conduction hole through the gap between the first protective shell and the first cone cap for hydraulic oil conduction.

[0006] Furthermore, the first protective shell has a tapered end design, and the tapered end is provided with a threaded groove.

[0007] Furthermore, docking support blocks are fixed at both ends of the first protective shell, and positioning spring buckles are elastically connected to the docking support blocks.

[0008] Furthermore, a threaded sleeve is rotatably provided on the support ring, the support ring is fixed to the protective shell, and docking blocks are fixed on the front and rear sides of the protective shell, with docking holes opened on the docking blocks.

[0009] Furthermore, the positioning spring buckle is elastically pressed against the docking hole, and a conduction hole is provided on the second guide transmission seat.

[0010] Furthermore, anti-slip grooves are provided on the first protective shell and the protective shell.

[0011] The beneficial effects of this invention are as follows: 1. This invention utilizes a first connecting locking structure. Within this structure, a first protective shell is fixed to a first guide transmission seat. The first guide transmission seat has a conduction hole for hydraulic oil conduction. A first spring retraction rod is telescopically connected to the support. This rod is fixed to a docking extrusion rod via a first conical cap, a first blocking block, and a docking extrusion rod. The first protective shell has a tapered end design. When the docking extrusion rod extrudes, it drives the first conical cap and the first blocking block to move. At this time, a gap is created between the first blocking block and the first protective shell, allowing hydraulic oil conduction. Simultaneously, a docking connecting block is adapted to the docking support block. A positioning spring buckle is adapted to the docking hole. When the block reaches the appropriate position, the spring buckle engages with the docking hole, positioning and fixing the docking support block and the docking connecting block. This ensures the stable connection performance of the first and second connecting locking structures, thereby reinforcing the connection while quickly locking it in place, preventing connection instability.

[0012] 2. This invention utilizes a second connecting locking structure. Within this structure, the second guide transmission seat is elastically and telescopically connected to a second blocking block, a second cone cap, and a second mating extrusion rod via a second spring retraction rod. A support collar is fixedly mounted on the protective shell, and a threaded sleeve is rotatably mounted on the support collar. The threaded sleeve is threadedly fastened to the first protective shell. Hydraulic oil is guided through the gap between the second blocking block and the protective shell, and introduced through the transmission hole on the second guide transmission seat. This allows the hydraulic oil to be guided into the first protective shell via the support collar and the threaded sleeve, thus achieving hydraulic oil transmission control.

[0015] The present invention will now be further described with reference to the accompanying drawings.

[0016] like Figures 1-4 A quick-connect locking device for hydraulic oil pipes includes a first locking structure 1 and a second locking structure 2, wherein the side end of the first locking structure 1 is fixedly connected to the second locking structure 2. The first connecting locking structure 1 includes a first protective shell 3, a first guide transmission seat 4 fixedly disposed inside the first protective shell 3, a conduction hole 5 opened on the first guide transmission seat 4, a support 6 fixedly disposed at the center side end of the first guide transmission seat 4, a first spring retraction rod 7 telescopically connected to the support 6, a first cone cap 8 fixedly connected to the side end of the first spring retraction rod 7, a first blocking block 9 fixedly connected to the side end of the first cone cap 8, and a first blocking block 9 fixedly connected to the side end of the first blocking block 9 fixedly connected to the docking extrusion rod 10.

[0017] The first connecting locking structure 1 is used for hydraulic oil conduction. It is elastically slidably connected to the first housing 3 via the first spring retraction rod 7, the first plugging block 9, and the first cone cap 8. When the first plugging block 9 is pressed, a gap exists between it and the first housing 3. Hydraulic oil passes through this gap to the first cone cap 8, and then through the gap between the first housing 3 and the first cone cap 8, it is guided to the conduction hole 5 for hydraulic oil conduction. The first housing 3 is fixed to the first guide transmission seat 4 by the first connecting locking structure 1. The first guide transmission seat 4 has a conduction hole 5 for hydraulic oil conduction. The first spring retraction rod 7 is telescopically connected to the support 6. The first spring retraction rod 7 passes through the first cone cap 8... The cap 8, the first blocking block 9, and the docking extrusion rod 10 are fixed together. The side end of the first protective shell 3 is designed with a tapered opening. When the docking extrusion rod 10 extrudes, it drives the first tapered cap 8 and the first blocking block 9 to move. At this time, the first blocking block 9 will create a gap with the first protective shell 3, which can transmit hydraulic oil. At the same time, the docking support block 12 is adapted to be connected to the docking connecting block 13. The positioning spring buckle 11 is adapted to be connected to the docking hole 14. When the appropriate position is reached, the positioning spring buckle 11 and the docking hole 14 are spring-locked together to fix the docking support block 12 and the docking connecting block 13, ensuring the connection stability of the first connecting locking structure 1 and the second connecting locking structure 2. Thus, while quickly connecting and locking, the connection is reinforced to avoid connection instability.

[0018] The first protective shell has a tapered opening on one side, and the tapered opening has a threaded groove.

[0019] The first protective shell 3 is fixedly provided with docking bearing blocks 12 at both the front and rear ends, and the docking bearing blocks 12 are elastically connected with positioning spring buckles 11.

[0020] The second connecting locking structure 2 includes a second guide transmission seat 20. A second spring retraction rod 19 is telescopically connected to the side end of the second guide transmission seat 20. The two ends of the second spring retraction rod 19 are fixed to the second cone cap 18. The side end of the second cone cap 18 is fixedly connected to the second blocking block 17. A docking extrusion rod 10 is fixedly provided on the side end of the second blocking block 17. The docking extrusion rod 10 and the second blocking block 17 slide within the support collar 16.

[0021] The second connecting locking structure 2 is used for the engagement and transmission of the first connecting locking structure 1. A protective shell is fixedly installed on the second guide transmission seat 20. The front end of the protective shell is fixed to the support collar 16. The threaded sleeve 15 rotates on the support collar 16 and is threadedly connected to the first protective shell 3. A second docking compression rod 10 is fixedly installed at the center front end of the second blocking block 17. The two docking compression rods 10 compress to form a transmission channel. The docking bearing block 12 and the docking connecting block 13 are fastened by the positioning spring buckle 11 and the docking hole 14. By installing the second connecting locking structure 2, the second connection... The second guide transmission seat 20 inside the locking structure 2 is elastically and telescopically connected to the second blocking block 17, the second cone cap 18 and the second mating extrusion rod 10 via the second spring contraction rod 19. A support collar 16 is fixedly installed on the protective shell, and a threaded sleeve 15 is rotatably installed on the support collar 16. The threaded sleeve 15 is threadedly fastened to the first protective shell 3. The oil is guided through the gap between the second blocking block 17 and the protective shell, and introduced through the conduction hole 5 on the second guide transmission seat 20. Thus, it is guided into the first protective shell 3 through the support collar 16 and the threaded sleeve 15, thereby realizing the transmission control of hydraulic oil.

[0022] A threaded sleeve 15 is rotatably mounted on the support collar 16. The support collar 16 is fixed to the protective shell. Connecting blocks 13 are fixed on the front and rear sides of the protective shell. Connecting holes 14 are opened on the connecting blocks 13.

[0023] The positioning spring buckle 11 is elastically pressed against the docking hole 14, and the second guide transmission seat 20 is also provided with a transmission hole 5.

[0024] First protective shell 3. Anti-slip grooves are provided on the protective shell.

[0025] Working principle: When needed, the user aligns and inserts the first connecting locking structure 1 and the second connecting locking structure 2, then presses the positioning spring buckle 11, causing the docking block 13 to enter the docking support block 12. Upon reaching the designated position, the positioning spring buckle 11 pops out through the docking hole 14, securing the docking block 13 and the docking support block 12. At this time, the two docking compression rods 10 compress the connection. The user then screws on the threaded sleeve 15, causing it to rotate on the support ring 16. The threaded sleeve 15 is threadedly connected to the first protective shell 3, reinforcing the connection and thus securing the first connecting locking structure 1 and the second connecting locking structure 2 at their center positions. Hydraulic oil flows through the second guide... The hydraulic oil is introduced into the protective housing via the transmission seat 20, passing through the gap between the second cone cap 18 and the protective housing, and reaching the second blocking block 17. At this point, a gap exists between the second blocking block 17 and the protective housing. The hydraulic oil is conducted to the first protective housing 3 via the support collar 16 and threaded sleeve 15, then through the first blocking block 9 and the first cone cap 8 to the center of the first protective housing 3, and finally discharged through the conduction hole 5 on the first guide transmission seat 4, thus completing the hydraulic oil discharge process. The first protective housing 3 is fixed to the first guide transmission seat 4 by installing the first connecting locking structure 1. The first guide transmission seat 4 has a conduction hole 5 for hydraulic oil conduction. A first spring is telescopically connected to the support 6. Rod 7, the first spring retraction rod 7, is fixed to the docking extrusion rod 10 via the first cone cap 8 and the first blocking block 9. The side end of the first protective shell 3 has a tapered design. When the docking extrusion rod 10 extrudes, it drives the first cone cap 8 and the first blocking block 9 to move. At this time, the first blocking block 9 will create a gap with the first protective shell 3, which can transmit hydraulic oil. At the same time, the docking support block 12 is adapted to be connected to the docking connecting block 13. The positioning spring buckle 11 is adapted to be connected to the docking hole 14. When it reaches the appropriate position, the positioning spring buckle 11 and the docking hole 14 are spring-locked together to position and fix the docking support block 12 and the docking connecting block 13, ensuring the connection stability of the first connecting locking structure 1 and the second connecting locking structure 2, thereby achieving rapid connection and locking. To reinforce the connection and prevent instability, a second connecting locking structure 2 is installed. Within this structure, the second guide transmission seat 20 is elastically connected to a second blocking block 17, a second cone cap 18, and a second mating extrusion rod 10 via a second spring retraction rod 19. A support collar 16 is fixedly mounted on the protective shell, and a threaded sleeve 15 is rotatably mounted on it. The threaded sleeve 15 is threadedly fastened to the first protective shell 3. Oil is guided through the gap between the second blocking block 17 and the protective shell, and introduced through the transmission hole 5 on the second guide transmission seat 20. This allows the oil to be guided into the first protective shell 3 via the support collar 16 and the threaded sleeve 15, thus achieving hydraulic oil transmission control and completing the operation.
