Technical Field

[0001] The utility model relates to the field of motor pumps, in particular to a relay bundling structure of a gear pump. Background Art

[0002] Some motor pumps require a relay, primarily for various protection functions and to facilitate circuit control. The relay uses an electromagnetic mechanism to control large currents with small currents. It converts parameters such as voltage and current within the control circuit to enable on / off control of the motor pump. The relay manufacturer itself is often different from that of the gear pump, resulting in a significant gap in technology. Therefore, the primary challenge lies in stably bundling and installing components from these two fields and specifications to form a complete gear pump assembly. Utility Model Content

[0006] The advantages of this technical solution are primarily that the bonding sheet retains two mounting options, which can be selected based on the specific needs of the motor being used, thus accommodating a wide variety of motor specifications. First, if the motor's outer wall has existing mounting locations, the notched holes can be used to pass fasteners such as bolts. Second, if a suitable mounting location is lacking, a clamp can be used for direct, wraparound fastening. The clamp does not require a notched hole, but the upward-turned spikes serve to limit the clamp's position, preventing axial loosening between the clamp and the bonding sheet.

[0007] As a further improvement of the present invention, the number of the upward-turned thorns is four, and the lines connecting the four upward-turned thorns in sequence can form a rectangle, and the same side of the clamp is provided with two upward-turned thorns.

[0008] The beneficial effect of adopting the above technical solution is that the four upward-turned thorns just limit the left and right loosening and twisting of the clamp.

[0009] As a further improvement of the present invention, the bonding sheet is provided with a punched hole, and the bonding sheet at the hole is partially bent 90 degrees to form an upward thorn.

[0010] The beneficial effect of adopting the above technical solution is that the upward thorn can be formed by stamping and bending, which is convenient for processing.

[0011] As a further improvement of the present invention, the bonding sheet has two notched holes, and the notches of the two notched holes face in opposite directions.

[0012] The beneficial effect of adopting the above technical solution is that assembly can be achieved with two bolts, and the notched shape of the notched hole also facilitates quick disassembly and assembly with the bolts.

[0013] As a further improvement of the present invention, the clamp includes a C-shaped ring and a bolt rod, and the bolt rod connects the two ends of the C-shaped ring.

[0014] The beneficial effect of adopting the above technical solution is that the bolt rod can tighten the C-shaped ring through its own knob.

[0015] As a further improvement of the present invention, the clamp is further in contact with the base, the motor and the base are both in contact with the inner ring of the clamp, and the base has a plurality of through holes.

[0016] The beneficial effect of adopting the above technical solution is that the base can provide a larger fixing position, for example, making it easier for the entire assembly to be fixed on the ground.

[0017] As a further improvement of the present invention, some through holes have more than one inner diameter value.

[0018] The beneficial effect of adopting the above technical solution is that the specifications of the bolts passing through the through holes can also be selected according to actual conditions.

[0019] As a further improvement of the present invention, the base includes a curved panel, the convex surface of the curved panel is in contact with the inner ring of the clamp, the two sides of the curved panel are vertically connected with side panels, the side of the side panel facing away from the curved panel is vertically fixed with an outer edge, the two outer edges coincide with the same spatial plane, and the through hole is located on the outer edge.

[0021] As a further improvement of the present invention, the sizes of the base, the fitting sheet and the clamp gradually decrease along the axial direction of the motor.

[0022] The beneficial effect of adopting the above technical solution is that the clamp plays a role of embracing and fixing, and the thickness of the clamp itself does not need to be too thick.

[0023] As a further improvement of the present invention, when the clamp is assembled with the fitting sheet, the C-shaped ring covers the notch hole.

[0024] The beneficial effect of adopting the above technical solution is that: in this way, the notch hole is not likely to cause the bottom of the C-shaped ring to be suspended, which can ensure the stability of the C-shaped ring. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The following is a further detailed description of the present invention in conjunction with specific embodiments:

[0036] The motor 1, the pump body 2, and the relay 3 constitute a complete and marketable gear pump assembly.

[0037] The advantages of this technical solution are primarily that the bonding sheet retains two mounting options, which can be selected based on the specific needs of the motor being used, thus accommodating a wide variety of motor specifications. First, if the motor's outer wall has existing mounting locations, the notched holes can be used to pass fasteners such as bolts. Second, if a suitable mounting location is lacking, a clamp can be used for direct, wraparound fastening. The clamp does not require a notched hole, but the upward-turned spikes serve to limit the clamp's position, preventing axial loosening between the clamp and the bonding sheet.

[0038] In some other embodiments of the present invention, the number of the upward-turned thorns 73 is four, and the lines connecting the four upward-turned thorns 73 in sequence can form a rectangle, and the same side of the clamp 6 has two upward-turned thorns 73 .

[0039] The beneficial effect of adopting the above technical solution is that the four upward-turned thorns just limit the left and right loosening and twisting of the clamp.

[0040] In some other embodiments of the present invention, the bonding sheet 7 has a punched hole 72 , and the bonding sheet 7 is partially bent 90° at the hole 72 to form an upward burr 73 .

[0041] The beneficial effect of adopting the above technical solution is that the upward thorn can be formed by stamping and bending, which is convenient for processing.

[0042] In some other embodiments of the present invention, the bonding sheet 7 has two notch holes 71 , and the notches of the two notch holes 71 face opposite directions.

[0043] The beneficial effect of adopting the above technical solution is that assembly can be achieved with two bolts, and the notched shape of the notched hole also facilitates quick disassembly and assembly with the bolts.

[0044] In some other embodiments of the present invention, the clamp 6 includes a C-shaped ring 61 and a bolt rod 62 , and the bolt rod 62 connects two ends of the C-shaped ring 61 .

[0045] The beneficial effect of adopting the above technical solution is that the bolt rod can tighten the C-shaped ring through its own knob.

[0046] In other embodiments of the present invention, the clamp 6 further contacts the base 5 , and the motor 1 and the base 5 both contact the inner ring of the clamp 6 . The base 5 has a plurality of through holes 54 .

[0047] The beneficial effect of adopting the above technical solution is that the base can provide a larger fixing position, for example, making it easier for the entire assembly to be fixed on the ground.

[0048] In other embodiments of the present invention, the plurality of through holes 54 have more than one inner diameter value.

[0049] The total number of through holes 54 is an integral multiple of the number of types of inner diameter values ​​thereof.

[0050] The beneficial effect of adopting the above technical solution is that the specifications of the bolts passing through the through holes can also be selected according to actual conditions.

[0051] In other embodiments of the present invention, the base 5 includes a curved panel 51, the convex surface of the curved panel 51 contacts the inner ring of the clamp 6, and the two sides of the curved panel 51 are vertically connected with side panels 52. The side of the side panel 52 facing away from the curved panel 51 is vertically fixed with an outer edge 53. The two outer edges 53 coincide with the same spatial plane, and the through hole 54 is located on the outer edge 53.

[0052] The beneficial effect of adopting the above technical solution is that the outer edge of the base is responsible for direct surface contact and fixation with the outside.

[0053] In other embodiments of the present invention, the sizes of the base 5 , the fitting sheet 7 , and the clamp 6 gradually decrease along the axial direction of the motor 1 .

[0054] The beneficial effect of adopting the above technical solution is that the clamp plays a role of embracing and fixing, and the thickness of the clamp itself does not need to be too thick.

[0055] In other embodiments of the present invention, when the clamp 6 and the fitting sheet 7 are assembled, the C-shaped ring 61 covers the notch hole 71 .

[0056] The beneficial effect of adopting the above technical solution is that: in this way, the notch hole is not likely to cause the bottom of the C-shaped ring to be suspended in the air, which can ensure the stability of the C-shaped ring.

[0057] like Figures 1 to 5 , a double-sealing-ring oil plug of a gear pump, comprising: an oil plug column 4, which can be assembled with a pump body 2, and the pump body 2 has an oil hole for accommodating the oil plug column 4; a sealing ring, which is sleeved on the oil plug column 4, and the outer wall of the oil plug column 4 has a groove for accommodating the sealing ring, and the sealing ring includes a first sealing ring 8 and a second sealing ring 9 which are coaxially arranged with each other, the cross-sectional profile of the first sealing ring 8 is circular, and the cross-sectional profile of the second sealing ring 9 is elliptical, the major axis of the ellipse is parallel to the axis of the oil plug column 4, and the depth of the second sealing ring 9 in the oil hole is deeper than the depth of the first sealing ring 8 in the oil hole.

[0058] The beneficial effect of adopting the above technical solution is that the oil plug column of the present application can play a basic disassembly and assembly function and realize the basic oil draining and maintenance functions. In addition, the double sealing ring design has better sealing performance than the single sealing ring. Secondly, the two sealing rings are not simply existing sealing rings, and the front sealing ring is relatively flat, that is, the radial thickness of the second sealing ring is thinner than its axial thickness, so the radial volume of the second sealing ring is not large, which facilitates the entire oil plug column to enter and exit the oil hole without causing much assembly resistance, and the axial size of the relative sealing ring involved in the sealing is large, which is a technical detail that the traditional sealing ring with a circular cross-section does not have. Finally, the pump body can form a gear pump combination with other components as a whole.

[0059] In other embodiments of the present invention, the inner ring diameter of the first sealing ring 8 is larger than the inner ring diameter of the second sealing ring 9 .

[0060] The beneficial effect of adopting the above technical solution is that the oil plug column is a stepped shaft, and different sealing rings adapt to the local diameter value of the oil plug column.

[0061] In other embodiments of the present invention, the minor axis of the elliptical cross-sectional profile of the second sealing ring 9 is smaller than the diameter of the circular cross-sectional profile of the first sealing ring 8 .

[0062] The beneficial effect of adopting the above technical solution is to ensure that the second sealing ring is radially thinner.

[0063] In some other embodiments of the present invention, the first sealing ring 8 and the second sealing ring 9 are made of rubber or silicone, and the oil plug 4 is an integrated metal part.

[0064] The beneficial effect of adopting the above technical solution is that the sealing ring is made of a flexible and elastic material.

[0065] In other embodiments of the present invention, the groove includes a first groove 42 and a second groove 41 extending along the circumferential direction. The first groove 42 and the second groove 41 are respectively assembled with the first sealing ring 8 and the second sealing ring 9; the inner wall of the second groove 41 has two internal corners, and the inner wall of the first groove 42 has one internal corner.

[0066] The advantages of this technical solution are that the groove provides a designated installation location for the sealing ring, preventing it from loosening axially. The first and second grooves also have different shapes, with the second groove providing a stronger wrapping effect, preventing the second sealing ring from contacting the inner wall of the oil hole and being pulled out.

[0067] In other embodiments of the present invention, the depth of the second groove 41 is smaller than the minor axis of the cross-sectional elliptical profile of the second sealing ring 9 , and the width of the second groove 41 is equal to the major axis of the cross-sectional elliptical profile of the second sealing ring 9 .

[0068] The beneficial effect of adopting the above technical solution is that the second groove just clamps the second sealing ring, but also exposes the outer edge of the second sealing ring to allow it to elastically seal with the inner wall of the oil hole.

[0069] In other embodiments of the present invention, the included angles of the internal angles are all right angles.

[0070] The beneficial effect of adopting the above technical solution is that the right-angled internal corner has a better limiting effect on the sealing ring.

[0071] like Figure 3 As shown, in other embodiments of the present invention, the oil plug 4 has an external thread section 43 , and the external thread section 43 is located between the first sealing ring 8 and the second sealing ring 9 .

[0072] The inner wall of the oil hole is provided with an internal thread section.

[0073] The beneficial effect of adopting the above technical solution is that the external thread section is convenient for thread fixation.

[0074] In other embodiments of the present invention, the oil plug 4 includes an outer hexagonal section 44 , and the outer hexagonal section 44 is located on a side of the first sealing ring 8 facing away from the second sealing ring 9 .

[0075] The beneficial effect of adopting the above technical solution is that the outer hexagonal section is convenient for turning the oil plug with a wrench.

[0076] In other embodiments of the present invention, the outer wall of the oil plug 4 is recessed with a plurality of radial blind holes 45 , which are arranged in a ring array around the axis of the oil plug 4 , and are located between the external threaded section 43 and the second sealing ring 9 .

[0077] The above embodiments are only for illustrating the technical concept and features of the present invention. Their purpose is to enable people familiar with this technology to understand the content of the present invention and implement it. They are not intended to limit the scope of protection of the present invention.
