Description

Technical Field

[0001] This utility model relates to the technical field of connecting joints, and in particular to a quick-connect device for hydraulic lines of skid steer loaders. Background Technology

[0002] Large equipment such as loaders, forklifts and excavators generally use hydraulic drive to achieve specific actions such as loading and transportation. In the entire hydraulic system, power is transmitted through fluid in the pipeline. The pipeline is often designed to consist of multiple pipelines, and the fluid is sealed and connected between adjacent pipelines by means of joints.

[0003] Existing quick-connect devices for hydraulic lines of skid steer loaders, such as the connection joint disclosed in utility model patent application number 201520167729.8, mainly include a joint body with a central through hole. One end of the outer wall of the joint body has a tapered insertion section that mates with a tapered surface, and the other end has a cylindrical insertion section. In use, an extension platform is formed at the front end of the tapered insertion section. The outer wall of the extension platform is cylindrical, and the extension platform fills the cylindrical hole. This minimizes the length of the cylindrical hole, thereby reducing the intensity of the eddy current generated by the fluid in the cylindrical hole and reducing the pressure loss of the fluid along the flow path.

[0004] However, most existing connectors are not convenient to quickly plug in, are relatively complicated to assemble, and dust can easily enter the hydraulic device when not connected, affecting the cleanliness of the hydraulic oil. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a quick-connect device for hydraulic lines of skid steer loaders that not only seals the hydraulic oil during the disconnection process to prevent dust from entering the hydraulic device, but also facilitates quick and easy connection, thereby improving the connection speed.

[0006] This utility model discloses a quick-connect device for hydraulic lines of skid steer loaders, including a fixing mechanism; it also includes a limiting mechanism, a blocking mechanism, a connecting mechanism, and a sealing mechanism. The limiting mechanism is installed on the fixing mechanism for easy connection, the blocking mechanism is installed on the limiting mechanism to prevent hydraulic oil from overflowing, the connecting mechanism is installed on the connecting pipe, and the sealing mechanism is installed on the connecting mechanism for easy connection with the limiting mechanism. The fixing mechanism is connected to the hydraulic device, and the blocking mechanism prevents hydraulic oil from overflowing. When it is necessary to connect to the oil pipeline, the oil pipeline is connected to the connecting mechanism. The operator inserts the sealing mechanism into the limiting mechanism, and the sealing mechanism pushes open the blocking mechanism, allowing the hydraulic oil in the hydraulic device to enter the oil pipeline through the sealing mechanism and the connecting mechanism.

[0007] Preferably, the fixing mechanism includes an oil reservoir, a fixing pipe, and multiple sets of clamps. The oil reservoir has an internal cavity, the top end of the fixing pipe is connected to the bottom end of the oil reservoir, and the multiple sets of clamps are installed on the fixing pipe. The operator connects the fixing pipe to the oil outlet of the hydraulic device, and the sealing effect is enhanced by setting multiple sets of clamps. The hydraulic oil is transported to the oil reservoir through the fixing pipe.

[0008] Preferably, the limiting mechanism includes a connector, a hinge, and a dust cover. The bottom end of the connector is connected to the top of the oil reservoir. The hinge is installed on the connector, and the dust cover is installed on the hinge. The dust cover covers the oil drain port of the connector to prevent dust from entering the oil reservoir. When connection is required, the dust cover is opened, and the sealing mechanism cooperates with the connector to connect.

[0009] Preferably, the sealing mechanism includes multiple sets of springs, a sealing cap, and a plug. The connector has multiple sets of grooves inside, and the multiple sets of springs are respectively installed in the multiple sets of grooves of the connector. The top of the sealing cap is connected to the top of the multiple sets of springs, and the plug is installed on the sealing cap. The multiple sets of springs pull the sealing cap and the plug, and the sealing cap cooperates with the connector to seal the oil reservoir, preventing dust from entering the oil reservoir. The sealing effect is enhanced by setting the plug.

[0010] Preferably, the connecting mechanism includes a connecting pipe, a sleeve, a handle, and a positioning ring. The connecting pipe is connected to the oil supply pipe, and the sleeve is connected to the inside of the connecting pipe. The handle is installed on the sleeve, and the positioning ring is installed on the sleeve. The sleeve is inserted into the connector, and the insertion depth is positioned by setting the positioning ring. The handle makes it easy for the operator to rotate the sleeve, which facilitates rotation and insertion and reduces insertion resistance. Hydraulic oil enters the oil supply pipe through the sleeve and the connecting pipe.

[0011] Preferably, the sealing mechanism includes multiple sets of sealing rings, a filter cartridge, and a top plate. The multiple sets of sealing rings are all fitted onto the positioning ring, the filter cartridge is installed on the sleeve, and the top plate is installed on the filter cartridge. A limiting groove is opened inside the connector. The sealing effect is enhanced by setting multiple sets of sealing rings to be embedded in the limiting groove. The top plate pushes the sealing cover and plug forward to facilitate the hydraulic oil to enter the sleeve through the filter cartridge. The filter cartridge can also filter the hydraulic oil.

[0012] Compared with the prior art, the advantages of this utility model are as follows: the fixing mechanism is connected to the hydraulic device, and the hydraulic oil is prevented from overflowing by setting a sealing mechanism. When it is necessary to connect to the oil pipeline, the oil pipeline is connected to the connecting mechanism. The operator inserts the sealing mechanism into the limiting mechanism, and the sealing mechanism pushes open the sealing mechanism, so that the hydraulic oil in the hydraulic device can enter the oil pipeline through the sealing mechanism and the connecting mechanism.
