Description

Technical Field

[0001] The utility model relates to the field of hydraulic equipment, in particular to a transition joint used in a hydraulic system. Background Art

[0002] Hydraulic pipe joints are components that connect high-pressure oil pipes in hydraulic systems. Hydraulic pipe joints can be divided into hydraulic hoses, quick connectors, ferrule-type pipe joints, welding-type pipe joints, and transition-type pipe joints. Transition-type pipe joints connect different types of hydraulic system hoses or hydraulic system equipment hydraulic joints.

[0028] Example 1

[0029] Reference Figures 1 to 3 , this embodiment provides a transition joint for a hydraulic system, comprising,

[0030] The transition joint body 100 has an outer ring nut 200 mounted on its surface, and a filter element 101 is provided in the inner cavity of the transition joint body 100;

[0031] The locking assembly 300 includes a fixed box 301, which is fixedly connected to the front of the outer ring nut 200. A threaded block 302 is embedded on the outside of the fixed box 301. The inner cavity of the threaded block 302 is threadedly connected to a threaded rod 303. The inner side of the threaded rod 303 is rotatably connected to a movable plate 304 through a bearing. The inner side of the movable plate 304 is bolted with a clamping rod 305. The inner side of the clamping rod 305 passes through the fixed box 301 and the transition joint body 100 in sequence and is clamped with the inner cavity of the clamping slot.

[0032] Furthermore, the filter element 101 includes a frame 101a, which is arranged in the inner cavity of the transition joint body 100. The inner cavity of the frame 101a is sequentially installed with a first filter screen 101b and a second filter screen 101c from front to back, and slots are provided at the top and bottom of the frame 101a.

[0033] Furthermore, a fixed block 301a is bolted to the outside of the fixed box 301, and the outside of the threaded rod 303 passes through the fixed box 301 and is bolted to a rotating block 301b. A clamping hole is provided on one side of the rotating block 301b, and a clamping block 301c is clamped to the inner cavity of the clamping hole. A spring is fixedly connected to one side of the clamping block 301c, and one side of the spring is fixedly connected to one side of the fixed block 301a.

[0034] Furthermore, sealing rings are bonded to the top and bottom of the transition joint body 100 , and the inner ring of the sealing ring contacts the surface of the clamping rod 305 .

[0035] Furthermore, first sliding grooves 301d are provided on both sides of the inner cavity of the fixed box 301 , and the inner cavity of the first sliding groove 301d is slidably connected to the first slider 301e, and the opposite sides of the first slider 301e are bolted to the two sides of the movable plate 304.

[0036] Furthermore, a second sliding groove 301f is provided on the outer side of the fixing box 301, and a second slider 301g is slidably connected to the inner cavity of the second sliding groove 301f. The outer side of the second slider 301g is bolted to the inner side of the clamping block 301c.

[0037] Furthermore, a protective pad 305 a is bonded to the inner side of the clamping rod 305 .

[0038] Furthermore, pull rods 101a-1 are bolted to both sides of the front of the frame 101a.

[0039] Furthermore, the surface of the rotating block 301b is provided with anti-slip grooves.

[0040] Furthermore, the surface of the transition joint body 100 is sequentially provided with external threads from front to back.

[0041] It should be noted that the rotating block 301b is fixed by the clamping block 301c and the spring to prevent the rotating block 301b from rotating and causing the clamping rod 305 to move out of the clamping slot during use, causing the frame 101a to move. The sealing ring improves the sealing of the transition joint body 100. The first slider 301e limits the movable plate 304 and assists the movable plate 304 to move up and down, thereby improving the stability of the movable plate 304. The second slider 301g limits the clamping block 301c and assists the clamping block 301c to move. When the clamping rod 305 is inserted into the clamping slot, the protective pad 305a acts as a buffer. The anti-slip grooves improve the anti-slip performance of the rotating block 301b, making it easier for the user to rotate the rotating block 301b. The pull rod 101a-1 makes it easier for the user to pull the frame 101a out of the transition joint body 100.

[0042] During use, the user places the frame 101a into the transition joint body 100. At this time, the front of the pull rod 101a-1 is flush with the front of the transition joint body 100. Then the user moves the block 301c to the right. At this time, the block 301c squeezes the spring. Then the user rotates the rotating block 301b. The rotating block 301b drives the threaded rod 303 to rotate. At this time, the threaded rod 303 moves inward, so that the threaded rod 303 drives the moving plate 304 to move inward, and the moving plate 304 drives the clamping rod 305 to move inward. At this time, the clamping rod 305 passes through the transition joint body 100 and is inserted into the card slot. Then the clamping block 301c is inserted into the card hole to fix the rotating block 301b to complete the installation of the filter element 101.

[0043] In summary, through the structural design of the frame 101a, the first filter screen 101b and the second filter screen 101c, the liquid entering the transition joint body 100 is filtered to remove impurities in the liquid. Through the structural design of the threaded rod 303, the movable plate 304, the clamping rod 305 and the threaded block 302, the frame 101a can be quickly installed in the transition joint body 100 without the need for an independent filtering structure, which facilitates installation and maintenance.
