Description

Technical Field

[0001] The utility model relates to the technical field of foot-operated drive pumps, in particular to a foot-operated drive pump. Background Art

[0002] Most electric forklifts today use a power output technology mode that separates the mobile drive motor from the hydraulic drive motor to ensure that the power output of the forklift's hydraulic steering is met when the forklift is reversing, avoiding steering failure and ensuring the normal operation of the forklift. This separated structure design requires two sets of motors and motor controllers, which takes up a large structural space and is costly.

[0003] After searching, the utility model patent with Chinese patent number CN221214210U discloses a new type of electric forklift hydraulic oil pump drive device, which relates to the technical field of drive equipment, including a receiving frame body, a linkage mechanism, a clutch conversion mechanism and a reverse transmission mechanism. A hydraulic pump is installed at one end of the receiving frame body, a drive motor is installed at one end of the receiving frame body, and a linkage mechanism is installed at one end of the drive motor. The utility model is provided with a receiving frame body, a hydraulic pump, a drive motor, a clutch conversion mechanism and a reverse transmission mechanism. When the drive motor rotates counterclockwise, the connection between the upper card wheel and the driving gear is cancelled. The hydraulic lever is operated to move the lower card wheel forward on the bearing shaft until it engages with the linkage gear, so that the linkage gear drives the bearing shaft connected to the inner ring of the lower card wheel to rotate, thereby driving the lower card shaft wheel to rotate. The upper card shaft wheel is connected to the lower card shaft wheel by a belt, thereby driving the pump shaft at the middle end of the upper card shaft wheel to rotate clockwise, driving the hydraulic pump to supply oil to the steering system normally, so that the forklift can steer normally.

[0004] Compared with the existing technology, the utility model with Chinese patent number CN221214210U can change the oil supply inside the hydraulic pump by rotating the internal pump shaft clockwise or counterclockwise, so that the forklift can operate better.

[0005] However, in actual use of the above device, the existing drive pump can be operated in two modes by forward rotation and reverse rotation. However, such a drive pump cannot accurately adjust the speed. When precise processing is required, the speed of the drive pump can only be adjusted by shifting the gear, and the speed of the drive pump cannot be accurately adjusted. Utility Model Content

[0006] In order to overcome the problem that the existing driving pump can operate in two modes by forward and reverse rotation when working, but such a driving pump cannot accurately adjust the speed, so that when precise processing is required, the driving pump speed can only be adjusted by shifting gears, and the driving pump speed cannot be accurately adjusted. An embodiment of the present application provides a foot-operated driving pump, which drives the driving plate to rotate by stepping on the foot pedal. Since an installation groove is provided inside the driving box, a rotating component can be installed inside the installation groove, and an assembly rod is provided inside the installation groove, which makes the assembly rod more stable during the rotation process. Since both ends of the assembly rod extend to the outside of the driving box, and both ends of the assembly rod are fixedly connected to the driving plate, the bottom of the driving plate is fixedly connected to a connecting shaft, so that one end of the connecting shaft is fixedly connected to the foot pedal. When the driving plate rotates, it drives the assembly rod connected at one end to rotate, and when the rotation speed of the assembly rod needs to be adjusted, it is only necessary to adjust the rotation speed of the foot pedal to accurately adjust it. The required speed is achieved because a stabilizing groove is provided in the middle of the assembly rod, and a rotating gear is fixedly connected to the inside of the stabilizing groove, so that when the assembly rod rotates, it drives the rotating gear to rotate. Since the rotating gear is installed inside the stabilizing groove, the rotating gear is more stable when it rotates. Since a driving toothed belt is meshed on the outside of the rotating gear, and a driving gear is meshed on one end of the driving toothed belt, when the rotating gear rotates, it drives the external driving toothed belt to rotate. When the driving toothed belt rotates, it drives the driving gear meshed at one end to rotate. Since a rotating rod is connected to the inside of the driving gear, and the rotating rod extends to the outside of the drive box, when the driving gear rotates, it drives the internally connected rotating rod to rotate. Since one end of the rotating rod is connected to a driving ring, and the outside of the driving ring is connected to a turbine blade, one end of the driving ring extends to the inside of the driving pump. When the rotating rod rotates, it drives the driving ring at one end to rotate. When the driving ring rotates, it drives the driving pump at one end to start, thereby driving the pump to work.

[0007] The technical solution adopted by the embodiment of the present application to solve the technical problem is:

[0008] A foot-operated drive pump comprises a drive pump and a drive box, wherein the drive box is arranged on one side of the drive pump;

[0009] Among them, an installation groove is opened inside the driving box, and an assembly rod is arranged inside the installation groove. Both ends of the assembly rod extend to the outside of the driving box. Both ends of the assembly rod are fixedly connected with driving plates, and the bottom of the driving plate is fixedly connected with a connecting shaft, and one end of the connecting shaft is fixedly connected with a foot pedal.

[0010] In a possible implementation, a stabilizing groove is provided in the middle of the assembly rod, and a rotating gear is fixedly connected to the interior of the stabilizing groove.

[0011] In a possible implementation, a driving toothed belt is meshed with the outside of the rotating gear, and a driving gear is meshed with the inside of one end of the driving toothed belt.

[0012] In a possible implementation, a rotating rod is connected to the interior of the driving gear, and the rotating rod extends to the outside of the drive box.

[0013] In a possible implementation, one end of the rotating rod is connected to a driving ring, the outside of the driving ring is connected to a turbine blade, and one end of the driving ring extends to the inside of the driving pump.

[0014] In a possible implementation, a connecting pipe is provided at one end of the driving pump, and one end of the connecting pipe is connected to a flange connection port.

[0015] In a possible implementation, a water outlet pipe extends outward from the interior of the driving pump, and a water outlet is formed in the interior of the water outlet pipe.

[0016] In a possible implementation, the top of the drive box is connected to a seat plate, and one side of the seat plate is fixedly connected to a supporting plate.

[0017] In a possible implementation, the four corners of the bottom of the drive box are connected to support rods, and the bottoms of the support rods are fixedly connected to a stabilizing plate.

[0018] In summary, the present invention has at least one of the following beneficial technical effects:

[0019] 1. By stepping on the foot pedal, the driving plate is driven to rotate. Since the driving box is provided with a mounting slot inside, the rotating assembly can be installed inside the mounting slot, and the mounting slot is provided with an assembly rod, which makes the assembly rod more stable during the rotation process. Since both ends of the assembly rod extend to the outside of the driving box, and both ends of the assembly rod are fixedly connected to the driving plate, the bottom of the driving plate is fixedly connected to the connecting shaft, and one end of the connecting shaft is fixedly connected to the foot pedal. When the driving plate rotates, the assembly rod connected to one end is driven to rotate. When the rotation speed of the assembly rod needs to be adjusted, it only needs to be adjusted according to the rotation speed of the foot pedal to accurately adjust the required speed.

[0020] 2. By driving the driving ring to rotate, since the driving ring extends to the inside of the driving pump, the driving pump is driven to absorb water, and one end of the flange connection port at one end of the driving pump is connected to the water inlet pipe, so that the water inlet pipe flows into the inside of the connecting pipe, allowing water to enter the inside of the driving pump. When water enters the inside of the driving pump 1, it flows into the inside of the water outlet pipe above, thereby driving the pump for use. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The technical solution in the embodiments of the present application is to solve the problems of the above-mentioned background technology, and the overall idea is as follows:

[0028] Example 1:

[0029] This embodiment introduces the specific structure of a foot-operated drive pump. Figure 1-Figure 5 As shown, it includes a driving pump 1 and a driving box 2. The driving box 2 is arranged on one side of the driving pump 1. Since a mounting groove 3 is opened inside the driving box 2, a rotating component can be installed inside the mounting groove 3, and an assembly rod 4 is provided inside the mounting groove 3, so that the assembly rod 4 is more stable during the rotation process. Since both ends of the assembly rod 4 extend to the outside of the driving box 2, and both ends of the assembly rod 4 are fixedly connected to driving plates 5, the bottom of the driving plate 5 is fixedly connected to a connecting shaft 6, so that one end of the connecting shaft 6 is fixedly connected to a foot pedal 7. When it is necessary to rotate the assembly rod 4, the staff steps on the foot pedal 7 to drive the driving plate 5 to rotate. When the driving plate 5 rotates, it drives the assembly rod 4 connected at one end to rotate. When it is necessary to adjust the rotation speed of the assembly rod 4, it only needs to adjust the rotation speed of the foot pedal 7 to accurately adjust the required speed.

[0030] Among them, since a stable groove 8 is provided in the middle of the assembly rod 4, and a rotating gear 9 is fixedly connected to the inside of the stable groove 8, when the assembly rod 4 rotates, the rotating gear 9 is driven to rotate. Since the rotating gear 9 is installed inside the stable groove 8, the rotating gear 9 is more stable when rotating. Since the outside of the rotating gear 9 is meshed with a driving toothed belt 10, and one end of the driving toothed belt 10 is meshed with a driving gear 11, when the driving gear 11 rotates, the external driving toothed belt 10 is driven to rotate, and when the driving toothed belt 10 rotates, the driving gear 11 meshed at one end is driven to rotate;

[0031] At the same time, since the interior of the driving gear 11 is connected to the rotating rod 12, and the rotating rod 12 extends to the outside of the driving box 2, when the driving gear 11 rotates, the rotating rod 12 connected to the inside is driven to rotate. Since one end of the rotating rod 12 is connected to the driving ring 13, and the outside of the driving ring 13 is connected to the turbine blade 22, so that one end of the driving ring 13 extends to the inside of the driving pump 1, when the rotating rod 12 rotates, the driving ring 13 at one end is driven to rotate. When the driving ring 13 rotates, the driving pump 1 at one end is driven to start, thereby driving the pump 1 to work;

[0032] Among them, since one end of the driving pump 1 is provided with a connecting pipe 14, and one end of the connecting pipe 14 is connected to a flange connecting port 15, when the driving pump 1 needs to be used, the flange connecting port 15 on the outside of the connecting pipe 14 at one end is connected to the water pipe, so that the driving pump 1 can absorb water. Since the driving pump 1 has an outlet pipe 16 extending outward from the inside, and the outlet pipe 16 has an outlet 17, when the driving pump 1 draws water from the connecting pipe 14 into the inside, the water inside is transported outward through the outlet pipe 16.

[0033] Furthermore, since the top of the drive box 2 is connected to a seat plate 18, and one side of the seat plate 18 is fixedly connected to a backrest plate 19, when the drive pump 1 needs to be started, the user sits on the seat plate 18. In order to make the user more comfortable, the user's back can lean on the backrest plate 19, so that the user can use it more comfortably and conveniently. Since the four corners of the bottom of the drive box 2 are connected to support rods 20 for supporting the drive box 2, the drive box 2 is more stable when working, and the bottom of the support rod 20 is fixedly connected to a stabilizing plate 21 for stabilizing the support rod 20, so that the support rod 20 supports the drive box 2, so that the drive box 2 is more stable when moving.

[0034] By adopting the above technical solutions:

[0035] When the above design drives the pump 1 to be adjusted, the driving plate 5 is driven to rotate by stepping on the foot pedal 7. Since the installation slot 3 is provided inside the driving box 2, the rotating component can be installed inside the installation slot 3, and the assembly rod 4 is provided inside the installation slot 3, which makes the assembly rod 4 more stable during the rotation process. Since both ends of the assembly rod 4 extend to the outside of the driving box 2, and the two ends of the assembly rod 4 are fixedly connected to the driving plate 5, the bottom of the driving plate 5 is fixedly connected to the connecting shaft 6, so that one end of the connecting shaft 6 is fixedly connected to the foot pedal 7. When the driving plate 5 rotates, it drives the assembly rod 4 connected at one end to rotate. When the rotation speed of the assembly rod 4 needs to be adjusted, it is only necessary to adjust the rotation speed of the foot pedal 7 to accurately adjust the required speed. Since a stabilizing groove 8 is provided in the middle of the assembly rod 4, and a rotating gear 9 is fixedly connected to the inside of the stabilizing groove 8, when the assembly rod 4 rotates, it drives the rotating gear 9 to rotate. The moving gear 9 is installed inside the stable groove 8, so that the rotating gear 9 is more stable when rotating. Since the outside of the rotating gear 9 is meshed with a driving toothed belt 10, and one end of the driving toothed belt 10 is meshed with a driving gear 11, when the driving gear 11 rotates, it drives the external driving toothed belt 10 to rotate. When the driving toothed belt 10 rotates, it drives the driving gear 11 meshed at one end to rotate. Since the inside of the driving gear 11 is connected to a rotating rod 12, and the rotating rod 12 extends to the outside of the drive box 2, when the driving gear 11 rotates, it drives the internally connected rotating rod 12 to rotate. Since one end of the rotating rod 12 is connected to a driving ring 13, and the outside of the driving ring 13 is connected to the turbine blade 22, one end of the driving ring 13 extends to the inside of the driving pump 1, when the rotating rod 12 rotates, the driving ring 13 at one end is driven to rotate. When the driving ring 13 rotates, it drives the driving pump 1 at one end to start, thereby driving the pump 1 to work.

[0036] Example 2:

[0037] Based on Example 1, this example introduces the specific structure of the driving pump. A connecting pipe 14 is provided at one end of the driving pump 1. One end of the connecting pipe 14 is connected to a flange connection port 15. An outlet pipe 16 extends outward from the interior of the driving pump 1. An outlet port 17 is provided inside the outlet pipe 16.

[0038] Among them, the driving pump 1 can drive the driving ring 13 to rotate to drive the water inside the driving pump 1 to the outside. The flange connection port 15 at one end of the driving pump 1 is connected to other water pipes, so that water can enter the driving pump 1, and the driving pump 1 is connected to the top through the channel connected at the top, thereby making the water flow to the top.

[0039] By adopting the above technical solutions:

[0040] When the driving pump 1 needs to be started, the above design drives the driving ring 13 to rotate. Since the driving ring 13 extends to the inside of the driving pump 1, it drives the driving pump 1 to absorb water, and the flange connection port 15 at one end of the driving pump 1 is connected to the water inlet pipe, so that the water inlet pipe intakes water into the connecting pipe 14, allowing water to enter the driving pump 1. When water enters the driving pump 1, it flows into the water outlet pipe 16 above, thereby driving the pump 1 for use.

[0041] Finally, it should be noted that the above embodiments are merely examples for the purpose of illustrating the present invention and are not intended to limit the embodiments. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to provide an exhaustive list of all possible embodiments. However, any obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
