[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0028] like Figures 1 to 5 As shown, this utility model provides a hydraulic and pneumatic integrated training device, comprising:

[0029] Training platform 1 includes: base frame 11, tabletop 12, tabletop profile support 13, tabletop profile 14, and frame mounting bracket 15; tabletop 12 is fixedly connected to the top of base frame 11, tabletop profile support 13 is fixedly connected to tabletop 12, tabletop profile 14 is fixedly connected to tabletop profile support 13, and frame mounting bracket 15 is fixedly connected to the top of base frame 11.

[0030] The training box 2 includes: a frame 21, a rear cover plate 22, a component mounting plate 23, a mounting plate 24, a mounting panel 25, a facade profile 26, and a top rod 27. The frame 21 is fixedly connected to the frame mounting bracket 15, the rear cover plate 22 is fixedly connected to the rear of the frame 21, the component mounting plate 23 is fixedly connected to the upper front of the frame 21, the mounting plate 24 is installed inside the frame 21, the upper part of the mounting panel 25 is hinged to the frame 21, the facade profile 26 is fixedly connected to the mounting panel 25, and the top rod 27 is hinged to the lower part of the mounting panel 25. The top rod 27 is provided with a sliding groove 271, and the sliding groove 271 is provided with multiple slots 272 spaced at preset distances. The frame 21 is provided with a snap-fit ​​component 211, which cooperates with the sliding groove 271 and the slots 272 to achieve angle adjustment of the mounting panel 25.

[0031] In training platform 1, the tabletop profile 14 is mounted on the tabletop profile support 13. Since the tabletop profile support 13 is fixedly connected to the tabletop panel 12, and the tabletop panel 12 is fixedly connected to the top of the base frame 11, the tabletop profile 14 is fixed. The frame 21 of training box 2 is fixedly connected to the frame mounting bracket 15, thus training box 2 is mounted on training platform 1. Since the vertical profile 26 is fixedly connected to the mounting panel 25, and the upper part of the mounting panel 25 is hinged to the frame 21, the user can rotate the mounting panel 25. Simultaneously, the top rod 27 is hinged to the lower part of the mounting panel 25. The top rod 27 is provided with a sliding groove 271, and the sliding groove 271 is provided with multiple slots 272 spaced at preset intervals. The frame 21 is provided with a snap-fit ​​component 211. The locking element 211, in conjunction with the slide rail 271 and the locking slot 272, enables the angle adjustment of the mounting panel 25. Therefore, during the rotation of the mounting panel 25, the locking element 211 will be positioned at different locations on the slide rail 271 of the top rod 27. When the desired angle is reached, the locking element 211 can be engaged with the locking slot 272, thereby restricting the movement of the mounting panel 25. When the facade profile 26 is not in use, the frame 21 can be retracted, saving space. When the facade profile 26 is needed, the mounting panel 25 can be raised, increasing the available space for the installation of hydraulic components. Furthermore, the multiple locking slots 272 allow the mounting panel 25 to be adjusted at multiple angles and to lock and unlock automatically, providing a wide range of adjustable opening and closing angles, facilitating user operation or demonstrations from multiple angles. Simultaneously, for the hydraulic training system and the pneumatic training system, by installing replaceable hydraulic and pneumatic components on the table profile 14 and the facade profile 26, different hydraulic and pneumatic circuits can be formed, allowing for simultaneous comparative experiments or identical simulation experiments, thereby improving the training effect.

[0032] The tabletop 12 has a groove, which prevents hydraulic oil on the hydraulic components installed on the tabletop profile 14 from overflowing onto the ground, thus ensuring the cleanliness of the laboratory.

[0033] like Figure 7 As shown, in some embodiments, the push rod 27 is also provided with a through hole 273, the mounting panel 25 is provided with a mounting component 251, the mounting component 251 is provided with a screw hole, the bolt passes through the through hole 273 and is threadedly connected to the screw hole, and the push rod 27 rotates around the bolt as an axis through the through hole 273.

[0034] Furthermore, the slide groove 271 extends along the length of the top rod 27, and the slot 272 is provided on the upper side of the slide groove 271. The extension direction of the slot 272 forms a preset angle with the extension direction of the slide groove 271.

[0035] The slot 272 is located on the upper side of the slide 271. Therefore, when the mounting panel 25 is adjusted to the angle required by the user, the snap-fit ​​211 moves to the corresponding slot 272 position. Under the action of gravity, the snap-fit ​​211 snaps into the corresponding slot 272, thereby fixing the angle of the mounting panel 25. At the same time, the extension direction of the slot 272 and the extension direction of the slide 271 form a preset angle, which can prevent the snap-fit ​​211 from accidentally falling out of the slot 272 and improve the snap-fit ​​stability between the snap-fit ​​211 and the slot 272.

[0036] like Figure 4 and Figure 5 As shown, in some embodiments, the snap-fit ​​member 211 is provided with a screw hole and a bolt, and the bolt passes through the groove 271 and is threadedly connected to the screw hole.

[0037] During rotation, the mounting panel 25 can move the push rod 27, thereby allowing the slide groove 271 to slide on the bolt of the locking member 211. At the same time, the nut of the bolt of the locking member 211 can prevent the push rod 27 from falling off.

[0038] like Figure 1 and Figure 3 As shown, the training platform 1 further includes: a base plate 16 and a pump bracket 17. The base plate 16 is fixedly connected to the bottom of the base frame 11, and the pump bracket 17 is fixedly connected to the base plate 16. The pump bracket 17 is used to fix and install the hydraulic pump.

[0039] like Figures 1 to 3 As shown, the training platform 1 further includes four caster mounting plates 18, which are fixedly connected to the four corners of the bottom of the base frame 11. The caster mounting plates 18 are used to mount casters 19. The installation of the casters 19 facilitates the movement of the hydraulic and pneumatic integrated training device.

[0040] like Figure 1 and Figure 3 As shown, the training platform 1 further includes: two hydraulic branch pads 10, which are fixedly connected to the platform panel 12, and the two hydraulic branch pads 10 are located on both sides of the platform profile pad 13. The hydraulic branch pads 10 are used to install the oil collector and the oil distributor.

[0041] During hydraulic training, to prevent hydraulic oil from overflowing onto the platform profile 14, an oil collector can be used to collect it. This keeps the platform clean and facilitates waste oil collection. Simultaneously, the oil distributor can allocate oil from the hydraulic pump to different hydraulic components, facilitating quick connection and disconnection of oil circuits during training.

[0042] like Figure 6As shown, the component mounting plate 23 further includes a main power switch, indicator lights, buttons, intermediate relays, limit switches, and input / output control terminals.

[0043] Mounting plate 24 is a perforated plate, on which a switching power supply can be mounted to power the hydraulic and pneumatic integrated training device. Meanwhile, component mounting plate 23 houses a main power switch, indicator lights, buttons, intermediate relays, limit switches, and input / output control terminals for circuit control of the hydraulic and pneumatic integrated training device. The hydraulic and pneumatic integrated training device can perform both hydraulic and pneumatic training. By connecting hydraulic and pneumatic components to different input / output control terminals, separate hydraulic and pneumatic training can be conducted without interference, while also allowing for simultaneous training.

[0044] like Figure 1 As shown, the training box 2 further includes a hook 28, which is fixedly connected to the frame 21. The hook 28 can be used to suspend components.

[0045] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
