DETAILED DESCRIPTION
[0023] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.
[0024] like Figure 1-Figure 7As shown, a push plate connector with an indicator comprises a support frame 1, a cylinder 3 is arranged inside the support frame 1, a locking valve 33 is arranged on the cylinder barrel 31 of the cylinder 3, a cylinder front axle 6 and a cylinder rear axle 7 are arranged on the cylinder 3, an axial hole 12 is arranged on the contact side between the support frame 1 and the cylinder rear axle 7, a tiger's mouth 13 and a push plate mechanism 4 are arranged below the support frame 1, the push plate mechanism 4 comprises a slide plate 41, a hook 42 and a connecting ear plate 43, an indicating mechanism 5 is arranged on the slide plate 41, opposite sliding grooves 11 are arranged on both sides of the interior below the support frame 1, and an axis plate 14 is arranged on the tiger's mouth 13.
[0025] The length of the indicating mechanism 5 exceeds the left end surface of the slide plate 41 .
[0026] When the rod of the oil cylinder 3 is extended to clamp the shaft of the attachment to be connected, the outermost side of the indicating mechanism 5 is located inside the supporting frame 1 .
[0027] The slide plate 41 can slide in the slide groove 11 .
[0028] The hook 42 is disposed below the slide plate 41 .
[0029] The upper section of the shaft plate 14 is higher than the lowest point inside the jaws 13 .
[0030] The lock valve 33 has a self-locking function.
[0031] The supporting frame 1 is provided with a swing mechanism.
[0032] The connecting ear plate 43 is connected to the cylinder rod of the oil cylinder 3 via the oil cylinder front shaft 6 .
[0033] When working, the lock valve 33 is welded to the cylinder barrel 31, and the lock valve 33 has a self-locking function. The hydraulic oil enters the rodless chamber through the lock valve 33, and the cylinder rod of the oil cylinder 3 extends. When the oil is not flowing, the hydraulic oil in the rodless chamber cannot enter the oil inlet pipe through the lock valve 33 to prevent backflow. The slide plate 41 is arranged inside the slide groove 11 and can slide inside the slide groove 11. The cylinder rod of the oil cylinder 3 is connected to the connecting ear plate 43 through the front shaft of the oil cylinder 3. The cylinder rod of the oil cylinder 3 moves with the push plate mechanism 4 inside the support frame 1. When the cylinder rod of the oil cylinder 3 is not extended, the indicating mechanism 5 is located outside the support frame 1. When the cylinder rod of the oil cylinder 3 is extended to clamp the shaft of the attachment to be connected, the indicating mechanism 5 is located inside the support frame 1 to play an indicating role. A hook 42 is arranged at the lower part of the push plate mechanism 4 to connect the remaining attachments.
[0034] In the initial working state, the cylinder 3 is fully extended, and the push plate mechanism 4 is separated from the jaws, which has no limiting effect on the shaft. Then the attachment shaft is hung on the jaws 13, and then the cylinder 3 is fully retracted, and one side of the push plate mechanism 4 is pressed on the upper part of the attachment shaft. At this time, the space is smaller than the diameter of the attachment shaft, and the limiting mechanism 4 plays a limiting role. Then the cylinder 3 extends the hook 42 to hang another shaft of the attachment. At this time, the push plate mechanism 4 is still pressed on the attachment shaft to play a limiting role.
[0035] The double protection measures of the push plate mechanism 4 and the lock valve 33 improve the safety and reliability of the accessories after installation; by setting the push plate mechanism 4, the connector has an indication function, which is convenient for the operator to observe and more humane; a swing mechanism can be added to adapt to more occasions and has strong adaptability.
[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
