Description

Technical Field

[0001] This utility model relates to the field of diaphragm pumps, and in particular to a diaphragm pump motor foot mounting structure. Background Technology

[0002] Diaphragm pumps rely on the back-and-forth movement of the diaphragm to change the volume of the working chamber in order to draw in and discharge liquids. In practical use, diaphragm pumps are generally installed on the equipment they are used with (such as electric sprayers) via motor feet.

[0003] In the prior art, the motor of a diaphragm pump is connected to a motor mounting plate, and is connected to other structures of the diaphragm pump (such as diaphragm support, fluid chamber, etc.) through the motor mounting plate. To accommodate motor feet, a motor bracket or motor housing is generally installed outside the motor, which is connected to the motor mounting plate, and the motor feet are mounted on the motor bracket or motor housing.

[0004] This method of connecting motor feet requires the use of a motor bracket or motor housing, resulting in more parts, increased cost, and more assembly steps. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a diaphragm pump motor foot mounting structure, which directly sets the motor foot on the motor connecting plate, saving parts and simplifying the assembly process.

[0006] The technical solution provided by this utility model is as follows:

[0007] A diaphragm pump motor foot mounting structure includes a motor connecting plate, and motor feet are provided on the outer periphery of the motor connecting plate.

[0008] Furthermore, the outer periphery of the motor connecting plate is provided with an outwardly protruding mounting protrusion, and the mounting protrusion is provided with a mounting groove, which opens towards the side away from the motor connecting plate, and the motor foot is disposed in the mounting groove.

[0009] Furthermore, the longitudinal direction of the mounting groove is arranged along the axial direction of the motor connecting plate, and the lateral dimension of the mounting groove on the side closer to the motor connecting plate is greater than the lateral dimension of the mounting groove on the side farther away from the motor connecting plate.

[0010] Furthermore, the motor foot is provided with a mounting part that inserts into the mounting slot, and the lateral dimension of the mounting part on the side closer to the motor connecting plate is greater than the lateral dimension of the mounting part on the side farther away from the motor connecting plate.

[0011] Furthermore, the lateral cross-sectional shape of the mounting groove near the motor connecting plate is trapezoidal, and the lateral cross-sectional shape of the mounting groove away from the motor connecting plate is rectangular. The intersection of the trapezoid and the rectangle forms a stepped structure. The lateral cross-sectional shape of the mounting part is adapted to the lateral cross-sectional shape of the mounting groove.

[0012] Furthermore, the end of the mounting slot near the motor is a closed structure, while the end of the mounting slot away from the motor is a through structure.

[0013] Furthermore, a diaphragm support is provided at the end of the motor connecting plate away from the motor, and a protruding structure is provided on the outer periphery of the diaphragm support, which blocks the end of the mounting groove away from the motor.

[0014] Furthermore, the motor feet are shock-absorbing soft feet, and the motor feet are symmetrically distributed on the outer periphery of the motor connecting plate.

[0015] This utility model has the following beneficial effects:

[0016] This invention eliminates the need for a motor bracket or motor housing, instead placing the motor feet directly on the outer periphery of the motor connecting plate, thereby saving parts and simplifying the assembly process. Attached Figure Description

[0026] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0027] This utility model embodiment provides a diaphragm pump motor foot mounting structure, such as... Figure 1-10 As shown, it includes a motor connection plate 1, one end of which is used to connect to the motor 2 of the diaphragm pump (for example, by connecting via a first set of screws 13), and motor feet 3 are provided on the outer periphery of the motor connection plate 1.

[0028] This utility model eliminates the need for a motor bracket or motor housing, and instead directly places the motor foot 3 on the outer periphery of the motor connecting plate 1, thereby saving parts and simplifying the assembly process.

[0029] In one example, the outer periphery of the motor connecting plate 1 is provided with an outwardly protruding mounting protrusion 4, and the mounting protrusion 4 is provided with a mounting groove 5. The mounting groove 5 opens toward the side away from the motor connecting plate 1, and the motor foot 3 is disposed in the mounting groove 5.

[0030] Specifically, the longitudinal direction of the mounting groove 5 is set along the axial direction of the motor connecting plate 1, and the lateral dimension of the mounting groove 5 on the side closer to the motor connecting plate 1 (the lateral dimension refers to the dimension on the cross section perpendicular to the longitudinal direction of the mounting groove 5) is greater than the lateral dimension of the mounting groove 5 on the side farther away from the motor connecting plate 1.

[0031] Correspondingly, the motor foot 3 is provided with a mounting part 6 that is inserted into the mounting slot 5. The lateral dimension of the mounting part 6 on the side closer to the motor connecting plate 1 is greater than the lateral dimension of the mounting part 6 on the side farther away from the motor connecting plate 1.

[0032] For example, the transverse cross-section of the mounting groove 5 near the motor connecting plate 1 (the transverse cross-section refers to the cross-section perpendicular to the axial direction of the motor connecting plate 1) is trapezoidal 7, and the transverse cross-section of the mounting groove 5 away from the motor connecting plate 1 is rectangular 8. A stepped structure is formed at the junction of the trapezoidal 7 and the rectangular 8. The transverse cross-section shape of the mounting part 6 is adapted to the transverse cross-section shape of the mounting groove 5.

[0033] With the above configuration, a mounting groove 5 and a mounting part 6 similar to a barb are formed. When the mounting part 6 is installed in the mounting groove 5, the movement of the motor foot 3 outside the axial direction of the motor connecting plate 1 is restricted. The motor foot 3 cannot move in a direction outside the axial direction of the motor connecting plate 1, but can only move in the axial direction.

[0034] The end of the mounting slot 5 closest to the motor 2 is a closed structure 9, and the end of the mounting slot 5 furthest from the motor 1 is a through structure 10. When installing the mounting part 6 into the mounting slot 5, the mounting part 6 is inserted into the mounting slot 5 from one end of the through structure 10 and pushed all the way to the end of the closed structure 9.

[0035] At this time, the motor foot 3 can only move towards one end of the through structure 10 in the axial direction of the motor connecting plate 1, and cannot move towards one end of the closed structure 9, nor can it move in any direction other than the axial direction of the motor connecting plate 1.

[0036] To restrict the movement of motor foot 3 towards one end of the through structure 10, a diaphragm bracket 11 is provided at the end of motor connecting plate 1 away from motor 2 (i.e., one end of through structure 10). The diaphragm bracket 11 is connected to the end of motor connecting plate 1 away from motor 2. Furthermore, a protruding structure 12 is provided on the outer periphery of the diaphragm bracket 11. The protruding structure 12 blocks the end of mounting groove 5 away from motor 2, that is, blocks the end of through structure 10.

[0037] The protruding structure 12 of the diaphragm bracket 11 restricts the movement of the motor foot 3 toward one end of the through structure 10. Thus, the movement of the motor foot 3 in all directions is restricted, so that the motor foot 3 is fixed on the motor connecting plate 1.

[0038] The protruding structure 12 can be a screw post on the diaphragm support 11. The screw post also serves as a connection structure between the diaphragm support 11 and the motor connection plate 1. The diaphragm support 11 and the motor connection plate 1 are connected together by the second set of screws 14 on the screw post.

[0039] The aforementioned motor feet 3 can be shock-absorbing soft feet to reduce vibration during motor operation. There can be multiple motor feet 3, which are symmetrically distributed on the outer periphery of the motor connecting plate 1.

[0040] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
