Description

Technical Field

[0001] The utility model belongs to the technical field of the connection of anti - detachment devices, and particularly relates to a driving mechanism of a self - closing and locking anti - detachment device. Background Technique

[0002] The quick connector of a tanker is mainly used to connect the hose between the tanker and other equipment when the tanker transports liquid. The working principle of the quick connector of a tanker is that it can quickly connect and disconnect the hose between the tanker and other equipment. For fluid transportation, it can greatly improve the loading and unloading efficiency. For chemical liquids, such as petroleum derivatives, volatile, toxic and harmful liquids, it is necessary to ensure the tightness and reliability of the quick connector.

[0003] There are many problems in the manual docking method of the quick connector. The manual method of the quick connector uses the cooperation of a pull rod and a pull ring. That is, eccentric cam pull rods are respectively installed on both sides of the socket. When the plug shaft is inserted into the socket, the two - side pull rods are pressed down, and the cam principle is used to force the plug shaft to sink and contact the gasket to achieve the braking work. However, such a structure cannot be applied to the self - closing and locking anti - detachment device designed by the applicant. Summary of the Invention

[0004] The purpose of the utility model is to design a driving mechanism of a self - closing and locking anti - detachment device. After quick docking, the self - closing and locking anti - detachment device is braked through a transmission mechanism to ensure stable connection.

[0005] In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows:

[0006] The driving mechanism of the self - closing and locking anti - detachment device includes a self - closing and locking anti - detachment device. The front end of the self - closing and locking anti - detachment device is docked with a male connector, and the rear end is connected to a guiding mechanism. The guiding mechanism includes a valve body. A driving handwheel is installed on the valve body. The driving handwheel rotates a driving shaft. A driving wheel is arranged at the end of the driving shaft. The driving wheel drives a lead screw to rotate through a gear set. A slider on the lead screw is connected to the handle of the self - closing and locking anti - detachment device through a connecting rod.

[0007] Further, both ends of the lead screw are seated in the bearings of a fixing member, and the fixing member is installed on the valve body.

[0008] Further, a locking ratchet mechanism is installed on the driving handwheel.

[0009] Further, the gear set is arranged on the surface of the valve body. It includes a driven wheel meshing with the driving wheel. The driven wheel is coaxially arranged with a first bevel gear. The first bevel gear meshes with a second bevel gear on the lead screw.

[0010] Further, a transmission turbine is installed on the driving shaft in the valve body. The transmission turbine meshes with the gear of the transmission guiding mechanism. The transmission guiding mechanism drives the transmission valve core to move back and forth. A liquid - discharging colloid is installed at the front end of the transmission valve core.

[0011] The following beneficial effects can be obtained through the above technical solutions:

[0012] The driving mechanism of the present utility model can disconnect and dock the self-closing and locking anti-disconnection device, and at the same time, the valve core in the valve body also correspondingly blocks or communicates. The present utility model adopts a handwheel driving method, which is completely suitable for the self-closing and locking anti-disconnection device and also changes the existing braking and locking method based on the cam principle.

[0013] The driving mechanism of the present utility model can easily achieve the connection and disconnection of the male and female connectors, avoiding the need for manual operation of a wrench in traditional docking, saving most of the workload, and being conducive to establishing a mechanical basis for subsequent intelligent or automated operations. When disconnecting the connection, the residual liquid is discharged through the liquid discharge colloid at the front end of the transmission valve core to prevent the leakage of residual liquid.

[0017] The following further describes the present utility model with reference to the drawings:

[0018] As Figure 1-2 shown, the driving mechanism of the self-closing and locking anti-disconnection device includes a self-closing and locking anti-disconnection device 1. The front end of the self-closing and locking anti-disconnection device is docked with the male connector, and the rear end is connected to a guiding mechanism. The guiding mechanism includes a valve body 2. A driving handwheel 9 is installed on the valve body 2, and a locking ratchet mechanism is installed on the driving handwheel 9. The driving handwheel rotates the driving shaft 10. A driving wheel 3 is provided at the end of the driving shaft 10. The driving wheel 3 meshes with a driven wheel 4. The driven wheel 4 and the first bevel gear 11 are coaxially arranged and installed on the surface of the valve body. Both ends of the lead screw 6 are respectively seated in the bearings of the fixing member 5. The two fixing members are installed on the valve body. A second bevel gear 12 is provided at one end of the lead screw. The second bevel gear 12 meshes with the first bevel gear 11. A slider 7 is installed on the lead screw. The slider 7 is connected to the handle of the self-closing and locking anti-disconnection device 1 through a connecting rod 8. A transmission turbine 13 is installed on the driving shaft 10 in the valve body. The transmission turbine meshes with the gear of the transmission guiding mechanism 14. The transmission guiding mechanism drives the transmission valve core 15 to move back and forth. A liquid discharge colloid 16 is installed at the front end of the transmission valve core.

[0019] Usage method:

[0020] The self-closing and locking anti-disconnection device includes a female connector housing. The female connector sleeve is installed in the female connector housing, and a handle and a connecting rod mechanism are installed on the self-closing and locking anti-disconnection device.Figure 1 and 2 As shown in 2 , the rear end (left end) of the self-closing and locking anti-disengagement device is docked with the valve body. A drive shaft 10 is installed at the rear end of the valve body. A drive handwheel 9 is installed on one side of the drive shaft 10. A locking ratchet mechanism is installed on the drive handwheel 9. A driving wheel 3 is installed on the other side of the drive shaft 10. When the drive handwheel 9 rotates, it drives the driving wheel 3 to rotate, and transmits the power to the lead screw along the driven wheel, the second bevel gear and the first bevel gear. When the lead screw rotates, the slider 7 on it moves to the left (observed from the attached drawing). The connecting rod 8 pulls the handle to move to the left. Therefore, under the action of the linkage mechanism, the female connector sleeve extends out of the housing ( Figure 3 as shown in Figure 3 ), so as to facilitate docking with the male connector. At the same time, the transmission turbine 13 in the valve body rotates, transmits the power to the transmission guiding mechanism 14, and the transmission guiding mechanism drives the transmission spool to move to the right for plugging. When the male connector is completely inserted into the female connector sleeve ( Figure 2 as shown in Figure 2 ), rotate the drive handwheel 9 in the reverse direction. At this time, the slider 7 moves to the right and drives the handle to move from left to right. At the same time, the transmission turbine 13 and the guiding mechanism 14 drive the transmission spool to move to the left, so that the male and female connectors are connected.

[0021] In the above embodiment, the self-closing and locking anti-disengagement device inserts the male connector into the female connector sleeve. The balls on the female connector sleeve fall into a circle of grooves on the male connector to achieve quick docking. During docking, the front end of the female connector sleeve pushes the ring-shaped body, and the ring-shaped body moves the spool to the left through the ejector rod. At this time, the male and female connectors are completely docked successfully. The specific structure of this component can be seen in the technical solution of the self-closing and locking anti-disengagement device applied by the applicant on the same day, which details the structure and principle of the self-closing and locking anti-disengagement device.

[0022] The above are all preferred embodiments of the present invention. For those of ordinary skill in the art, without departing from the principle of the present invention, any modifications to various equivalent forms of the present invention fall within the protection scope of the appended claims of this application.
