Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] like Figures 1 to 11 As shown, the present invention provides a hydraulic pump connection device, comprising a workbench 1, a positioning block 2 is fixedly installed on the top of the workbench 1, a hydraulic pump body 3 is arranged on the top of the workbench 1, and a plug hole 4 is opened on the surface of the bottom end of the hydraulic pump body 3;

[0034] The limiting mechanism is arranged inside the workbench 1, and the limiting mechanism includes a limiting rod 5, the limiting rod 5 is fixedly connected to the inside of the workbench 1, and the surface of the limiting rod 5 is slidably connected to a slider 6, and the front and rear ends of the slider 6 are fixedly installed with a connecting plate 7, and the top of the connecting plate 7 is hinged with a push rod 8, and the top of the push rod 8 is hinged with a hinge block 9, and the top of the hinge block 9 is fixedly installed with a connecting plate 2 10 located at the top of the workbench 1, and the connecting plate 2 10 is L-shaped, and a moving plate is fixedly installed on the opposite side of the connecting plate 2 10 11, an insert block 12 located inside the positioning block 2 is fixedly installed on one side opposite to the movable plate 11, a transmission wheel 13 and a transmission wheel 2 14 are rotatably connected at the bottom end of the workbench 1, a transmission belt 15 is connected to the surface transmission of the transmission wheel 13 and the transmission wheel 2 14, a connecting block 16 is fixedly installed on the top end of the transmission belt 15, the top end of the connecting block 16 is fixedly connected to the bottom end of the slider 1 6, a motor 17 is fixedly installed on the rear end of the transmission wheel 2 14, and the output end of the motor 17 is fixedly connected to the rear side of the transmission wheel 2 14.

[0035] The above scheme is adopted: the operator places the hydraulic pump body 3 on the top of the workbench 1, and inserts the positioning block 2 into the inside of the socket 4, and then the motor 17 can be driven to rotate the transmission wheel 2 14, because the transmission wheel 2 14 and the transmission wheel 1 13 are connected to each other by the transmission belt 15 on the surface transmission, and then in the process of the transmission wheel 2 14 rotating, the transmission wheel 2 14 will drive the transmission belt 15 to drive the transmission wheel 1 13 to rotate, and then the transmission belt 15 will drive the connecting block 16 to move, and the connecting block 16 will drive the slider 1 6 to move on the surface of the limiting rod 5, and then the limiting rod 5 can limit the slider 1 6, and when the slider 1 6 moves, the slider 16 will drive connecting plate 17 to move, and connecting plate 17 will drive pushing rod 8 to rotate, and then pushing rod 8 will drive hinge block 9 to move relatively, and hinge block 9 will drive connecting plate 2 10 to move relatively, and connecting plate 2 10 will simultaneously drive moving plate 11 and plug block 12 to move, and plug block 12 will enter the interior of positioning block 2, and then moving plate 11 and plug block 12 can limit the hydraulic pump body 3, and finally through the movement of moving plate 11 and plug block 12, the hydraulic pump body 3 can be fixed on the top of the workbench 1 without using fixing bolts, so as to facilitate the operator to fix the hydraulic pump body 3.

[0036] like Figure 6 , Figure 8 and Fig.11 As shown, the fixing mechanism is arranged at the front end of the surface of the hydraulic pump body 3, and the fixing mechanism includes a low-pressure liquid inlet pipe 20, which is arranged at the front end of the surface of the hydraulic pump body 3, and a high-pressure liquid outlet 21 is provided at the top of the surface of the hydraulic pump body 3. A circular groove 22 is provided at the front end of the low-pressure liquid inlet pipe 20, and a sealing ring 23 is inserted in the circular groove 22. Both sides of the surface of the sealing ring 23 are provided with limiting holes 24. A connecting shell 25 located on the surface of the low-pressure liquid inlet pipe 20 is fixedly installed at the front end of the surface of the hydraulic pump body 3, and a spring 26 is fixedly installed at the top and bottom of the connection shell 25. A plug block 27 located inside the limiting hole 24 is fixedly installed on the opposite side of the spring 1 26, a tooth plate 28 is rotatably connected to the bottom end of the connecting shell 25, a bidirectional screw 29 is fixedly installed on the top of the tooth plate 28, a slider 2 30 is threadedly connected to the surface of the bidirectional screw 29, an extrusion plate 31 located on the opposite side of the plug block 27 is fixedly installed on the left end of the slider 2 30, a rack 32 is slidably connected inside the connecting shell 25, a connecting rod 33 is fixedly installed on the bottom end of the rack 32, and the bottom end of the connecting rod 33 is fixedly connected to the top of the front movable plate 11, and a liquid oil pipe 34 is provided at the rear end of the low-pressure liquid inlet pipe 20.

[0037] By adopting the above scheme: through the design of the fixing mechanism, the sealing ring 23 can be inserted into the inside of the annular groove 22, and then the limiting hole 24 will be aligned with the plug block 27. Since the bottom end of the connecting rod 33 is fixedly connected to the top end of the front movable plate 11, when the movable plate 11 moves backward, the front movable plate 11 will drive the connecting rod 33 to move, and the connecting rod 33 will drive the rack 32 to move. Because the rack 32 is meshed with the toothed plate 28, the rack 32 will drive the toothed plate 28 to rotate, and the toothed plate 28 will drive the bidirectional screw 29 to rotate. Since the bidirectional screw 29 is threadedly connected with the slider 2 30, when the bidirectional screw 29 rotates, the slider 2 30 will move relatively, and then the slider 2 30 will drive the extrusion plate 31 to move relatively, and then the opposite side of the extrusion plate 31 will contact the opposite side of the plug block 27, and will push the plug block 27 to move. When the plug block 27 moves, the spring 1 26 will be stretched, and then the plug block 27 will enter the inside of the limiting hole 24, and then the plug block 27 can fix the limiting hole 24, and then the oil pipe 34 filled with hydraulic oil can be connected with the low-pressure inlet pipe 20, and then the sealing ring 23 will enter the inside of the oil pipe 34, so as to increase the sealing performance of the device and avoid the leakage of hydraulic oil. After the low-pressure inlet pipe 20 is connected with the oil pipe 34, the hydraulic pump body 3 can be driven to work, and during the operation of the hydraulic pump body 3, the hydraulic oil in the oil pipe 34 will enter the inside of the hydraulic pump body 3 through the low-pressure inlet pipe 20, and when the hydraulic oil flows into the hydraulic system, high-pressure oil is formed, and as the pump wheel inside the hydraulic pump body 3 rotates, the high-pressure hydraulic oil will flow out from the inside of the high-pressure outlet 21;

[0038] When the limit on the hydraulic pump body 3 is cancelled, the movable plate 11 at the front end will push the connecting rod 33 and the rack 32 forward, then the tooth plate 28 will rotate in the opposite direction, and the bidirectional screw 29 will drive the extrusion plate 31 away from the surface of the plug block 27, then the compressed spring 1 26 will pull the plug block 27 away from the inside of the limit hole 24, and then the sealing ring 23 can be taken out and replaced to ensure the sealing of the device.

[0039] like Fig. 9 and Fig.10 As shown, a distribution box 35 is fixedly installed at the rear end of the surface of the hydraulic pump body 3, a baffle 36 is provided at the front end of the distribution box 35, a square groove 37 is opened at the rear end of the distribution box 35, a positioning ring 38 located inside the square groove 37 is fixedly installed at the front end of the baffle 36, through holes 39 are opened at the upper and lower ends of the surface of the positioning ring 38, a square shell 40 is fixedly installed at the top and bottom ends of the distribution box 35, a spring 41 is fixedly installed at the top of the square shell 40, a plug-in plate 42 located inside the positioning ring 38 is fixedly installed at the bottom end of the spring 41, a contact block 43 is fixedly installed at the top of the plug-in plate 42, and an extrusion block 44 is inserted at the rear end of the square shell 40.

[0040] With the above solution, all electronic components can be installed inside the distribution box 35 through the design of the distribution box 35. When the electronic components inside the distribution box 35 need to be maintained, the extrusion block 44 can be pulled out from the inside of the square shell 40, and then the compressed spring 41 will pull the plug 42 out of the through hole 39, thereby canceling the limit of the baffle 36, and then the baffle 36 can be removed, and then the operator can maintain the electronic components inside the distribution box 35;

[0041] After the maintenance is completed, the positioning ring 38 can be reinserted into the square groove 37, and then the bottom end of the insert plate 42 will be aligned with the surface of the through hole 39, and then the extrusion block 44 can be inserted into the square shell 40, and then the surface of the extrusion block 44 will contact the surface of the contact block 43, and then the contact block 43 can be pushed to move, and then the contact block 43 will push the insert plate 42 to re-enter the through hole 39, and then the baffle 36 and the positioning ring 38 can be re-fixed, and then the hydraulic pump body 3 can continue to be driven to work.

[0042] like Figure 5 As shown, a support groove 18 is provided inside the workbench 1 , a support block 19 is slidably connected inside the support groove 18 , and one side of the support block 19 is fixedly connected to the surface of the connecting plate 2 10 .

[0043] The above solution is adopted: through the design of the support groove 18 and the support block 19, when the connecting plate 2 10 moves, the connecting plate 2 10 will drive the support block 19 to move inside the support groove 18. Since the surface of the support block 19 contacts the inner wall of the support groove 18, the connecting plate 2 10 can be supported, thereby ensuring that the connecting plate 2 10 can move normally.

[0044] like Figure 8 and Fig.11 As shown, a filter plate 45 is provided inside the low-pressure liquid inlet pipe 20, and filter holes 46 are opened on the surface of the filter plate 45. The second plug block 27 is designed to be laterally symmetrical about the center of the annular groove 22, and the opposite sides of the plug block 27 are both in an arc design, and the opposite sides of the plug block 27 are both in contact with the inner wall of the annular groove 22.

[0045] The above scheme is adopted: through the design of the filter plate 45 and the filter hole 46, after the hydraulic oil enters the low-pressure inlet pipe 20, the hydraulic oil will pass through the filter hole 46, and the impurities in the hydraulic oil will be blocked by the filter plate 45, preventing the impurities in the oil from entering the hydraulic pump body and blocking the hydraulic pump body, causing it to fail to work normally. Through the design of the plug block 27, since the plug block 27 is an arc-shaped design, when the plug block 27 enters the limit hole 24, the opposite side of the plug block 27 will fit with the inner wall of the annular groove 22, thereby increasing the fixing effect of the sealing ring 23.

[0046] like Figure 2 and Figure 3 As shown, a protective shell 47 is fixedly installed at the front end of the connecting shell 25, and the rack 32 can enter the interior of the protective shell 47. Threaded plates 48 are fixedly installed at both left and right ends of the workbench 1, and the threaded plates 48 are designed to be longitudinally symmetrical about the center of the workbench 1.

[0047] The above scheme is adopted: through the design of the protective shell 47, when the rack 32 moves forward, since the size of the rack 32 is adapted to that of the protective shell 47, the rack 32 will enter the interior of the protective shell 47, and then the protective shell 47 can protect the rack 32; through the design of the threaded plate 48, the fixing thread can be inserted into the interior of the threaded plate 48, and then the workbench 1 can be fixed, thereby increasing the working stability of the device.

[0048] like Fig. 9 and Fig.10 As shown, the rear end of the contact block 43 is designed as a bevel, the bottom end of the front end of the extrusion block 44 is designed as a bevel, the number of the sockets 4 is four, and they are designed as square, and the size of the sockets 4 is compatible with the size of the positioning block 2.

[0049] The above scheme is adopted: through the design of the contact block 43 and the extrusion block 44, when the extrusion block 44 contacts the contact block 43, since the rear end of the contact block 43 is designed as a slope, and the slope at the front end of the extrusion block 44 is parallel to the slope at the rear end of the contact block 43, the resistance to contact with the contact block 43 can be reduced, and it is convenient for the extrusion block 44 to push the contact block 43 to move; through the design of the socket 4, after the positioning block 2 enters the inside of the socket 4, since the size of the socket 4 is adapted to the positioning block 2, when the plug-in block 12 enters the inside of the socket 4, the fixing effect on the hydraulic pump body 3 can be increased.

[0050] The working principle and use process of the present invention:

[0051] First, the operator can put the hydraulic pump body 3 on the top of the workbench 1, and insert the sealing ring 23 into the annular groove 22, and then make the positioning block 2 enter the inside of the socket 4. When the bottom end of the hydraulic pump body 3 contacts the top of the workbench 1, the motor 17 can be driven to rotate the transmission wheel 2 14, and the transmission wheel 2 14 will drive the transmission belt 15 and the transmission wheel 1 13 to rotate, and then the transmission belt 15 will drive the connecting block 16 and the slider 1 6 to move, and the slider 1 6 will drive the push rod 8 to rotate, and the push rod 8 will drive the hinge block 9 and the connecting plate 2 10 to move relative to each other, and then the connecting plate 2 10 will drive the moving plate 11 and the plug block 1 12 to move relative to each other, and then the plug block 12 will enter the interior of the positioning block 2, and then the moving plate 11 and the plug block 1 12 can fix the hydraulic pump body 3;

[0052] When the front moving plate 11 moves, the connecting rod 33 and the rack 32 are driven to move, the rack 32 drives the tooth plate 28 to move, and the tooth plate 28 drives the bidirectional screw 29 to rotate. When the bidirectional screw 29 rotates, the slider 2 30 and the extrusion plate 31 move relative to each other, and then the surface of the extrusion plate 31 contacts the opposite side of the plug block 27, and then the extrusion plate 31 pushes the plug block 27 to move. When the plug block 27 moves, the spring 1 26 is stretched, and then the plug block 27 enters the inside of the limiting hole 24. Since the size of the plug block 27 is consistent with the limiting hole 24, the sealing ring 23 can be fixed.

[0053] After the fixing is completed, the oil pipe 34 filled with hydraulic oil can be connected to the low-pressure liquid inlet pipe 20, and then the hydraulic pump body 3 can be driven. When the hydraulic pump body 3 is working, the hydraulic oil in the oil pipe 34 will enter the interior of the low-pressure liquid inlet pipe 20. When entering the interior of the low-pressure liquid inlet pipe 20, the filter plate 45 can filter the hydraulic oil, and then the hydraulic oil will enter the interior of the hydraulic pump body 3. When the hydraulic oil flows into the hydraulic system, high-pressure oil is formed, and as the pump wheel inside the hydraulic pump body 3 rotates, the high-pressure hydraulic oil will flow out from the inside of the high-pressure liquid outlet 21;

[0054] When working for a long time and it is necessary to maintain the electronic components inside the distribution box 35, the extrusion block 44 can be pulled out, and then the compressed spring 41 will pull the plug plate 42 to move, and then the operator can remove the baffle 36 and the positioning ring 38, and then the user can maintain the electronic components. After the maintenance is completed, the positioning ring 38 can be reinserted into the square groove 37, and the extrusion block 44 can be inserted into the square shell 40, and then the extrusion block 44 will contact the contact block 43, and will push the contact block 43 and the plug plate 42 to move, and then the plug plate 42 will enter the inside of the through hole 39, and then the baffle 36 and the positioning ring 38 can be placed at the rear end of the distribution box 35 again, and then the hydraulic pump body 3 can continue to be driven to work, and finally the operation process is completed.
