[0044] Example

[0045] Please refer to Figure 1-Figure 4 As shown, this embodiment provides a pressing jig for a fountain pump, which is used to press the sealing gasket at the wire entrance of the fountain pump. It includes a base 10, a bracket 11, a positioning base 12 and a pressing assembly 13; the bracket 11 is arranged on the base 10, the pressing assembly 13 is arranged on the bracket 11, and the positioning base 12 is located directly below the pressing assembly 13 and is arranged on the top of the base 10, which is used to fix the position of the workpiece to be pressed, avoid the position of the workpiece from being offset during the pressing operation, so that the pressing assembly 13 can be pressed accurately and the quality of the pressing can be ensured. In addition, a pressing rod 132 is provided on the driving rod 131 of the pressing assembly 13, which is coaxially detachably connected to the driving rod 131, and a hand crank 111 is provided on the bracket 11 to drive the driving rod 131 to move toward or away from the positioning base 12, and the hand crank 111 can drive the driving rod 131 and then drive the pressing rod 132 to press down toward the positioning base 12. The pressure rod 132 includes a first pressure rod 1321 and a second pressure rod 1322. The first pressure rod 1321 and the second pressure rod 1322 are separately arranged, that is, the second pressure rod 1322 is detachably arranged at the bottom of the first pressure rod 1321, so as to facilitate the replacement of the second pressure rod 1322. In order to avoid pressing the wire during the pressing operation, a evacuation groove 13221 with two ends connected is arranged in the middle of the bottom surface of the second pressure rod 1322. The evacuation groove 13221 is used to evade the wire. By adjusting the position of the second pressure rod 1322 plugged into the bottom of the first pressure rod 1321, the evacuation groove 13221 can be adjusted to a suitable position to evade the wire. The operation is simple and convenient.

[0046] Specifically, when performing the pressing operation, the second pressing rod 1322 is inserted into the bottom of the first pressing rod 1321, and the position of the second pressing rod 1322 is adjusted to adjust the avoidance groove 13221 to a suitable position to avoid pressing the wires during the pressing operation, and then the hand crank 111 is pressed, and under the drive of the hand crank 111, the driving rod 131 drives the pressing rod 132 to move vertically downward to the positioning base 12 and perform the pressing operation.

[0047] In this way, the pressing operation is simple and convenient, the production efficiency is high, and the labor intensity of manual operation can be effectively reduced. In addition, since the first pressing rod 1321 and the second pressing rod 1322 are separately arranged, it is convenient to adjust the position of the avoidance groove 13221, for example, by rotating the second pressing rod 1322, the avoidance groove 13221 is adjusted toward the positioning base 12, so that the avoidance groove 13221 avoids the wire, and after a long period of pressing operation, if there is damage, only the second pressing rod 1322 needs to be replaced, which is convenient for maintenance, and there is no need to replace the entire pressing rod 132, which can save production costs.

[0048] like Figure 3 and Figure 4 As shown, in this embodiment, a connecting portion 13222 is provided between the second pressing rod 1322 and the first pressing rod 1321 , and an annular groove 13223 and a sealing ring 13224 sleeved on the annular groove 13223 are provided on the connecting portion 13222 of the first pressing rod 1321 or the second pressing rod 1322 .

[0049] It should be noted that the connection portion 13222 may be a combination of a convex shaft and a groove, for example, a convex shaft is provided on the second pressure rod 1322, and a groove that cooperates with the convex shaft is provided on the first pressure rod 1321; conversely, the convex shaft may be provided on the first pressure rod 1321, and a groove is provided on the second pressure rod 1322 for cooperation. In order to improve the tightness of the connection between the first pressure rod 1321 and the second pressure rod 1322, at least one annular groove 13223 is provided on the connection portion 13222, and a sealing ring 13224 is sleeved in the annular groove 13223.

[0050] In a preferred embodiment, the sealing ring 13224 is a rubber ring or a silicone ring. Since both the rubber ring and the silicone ring have good resilience, they can be embedded in the annular groove 13223 to generate contact pressure, thereby improving the tightness of the fit between the groove and the convex shaft, while not affecting the rotation between the first pressure rod 1231 and the second pressure rod 1322.

[0051] like Figure 1 and Figure 2As shown, in this embodiment, the driving rod 131 is set through the bracket 11, a rack surface 1311 is set on one side of the driving rod 131, the hand crank 111 is provided with a gear (not shown in the figure) meshing with the rack surface 1311, and a rotating shaft 112 connected between the gear and the hand crank 111, and the rotating shaft 112 is rotatably set on the bracket 11.

[0052] Specifically, the hand crank 111 is rotated to drive the gear to rotate. When the gear rotates, it meshes and rotates relative to the rack surface 1311, driving the driving rod 131 to move vertically upward or downward, thereby completing the pressing operation.

[0053] like Figure 4 As shown, in this embodiment, a tightening member 1312 for locking the pressure rod 132 is disposed on the driving rod 131 .

[0054] Specifically, the first pressure rod 1321 is detachably connected to the driving rod 131, that is, the top of the first pressure rod 1321 is a connecting portion that is inserted into the driving rod 131, and the tightening member 1312 can be a bolt, and the tightening member 1312 is arranged at the bottom of the driving rod 131. After the first pressure rod 1321 is inserted into the driving rod 131, the tightening member 1312 is rotated to apply pressure toward the first pressure rod 1321, so that the top of the first pressure rod 1321 is tightened inside the driving rod 131, thereby ensuring the reliability of the connection between the first pressure rod 1321 and the driving rod 131.

[0055] like Figure 1 and Figure 2 As shown, in this embodiment, the pressing assembly 13 further includes a fixing plate 134 and a return spring 133. The fixing plate 134 is located above the bracket 11 and is arranged on the top of the driving rod 131. A guide rod 113 is arranged on the top of the bracket 11. The top surface of the guide rod 113 is higher than the top surface of the fixing plate 134. The return spring 133 is arranged between the top of the guide rod 113 and the fixing plate 134.

[0056] In this way, when performing the pressing operation, the hand crank 111 is rotated to drive the driving rod 131 and thus drive the fixed plate 134 to move vertically downward, and the reset spring 133 is stretched; after the pressing operation is completed, the hand crank 111 is released, and the reset spring 133 automatically contracts to drive the fixed plate 134 and thus drive the driving rod 131 to automatically reset, making the pressing operation more convenient and labor-saving.

[0057] like Figure 1 and Figure 2 As shown, in this embodiment, at least one limiting member 1341 is disposed on the fixing plate 134 to abut against or separate from the bracket 11 .

[0058] Specifically, the limiter 1341 can be a bolt, and the distance between the limiter 1341 and the top of the bracket 11 can be adjusted. When the pressing operation is performed, when the fixing plate 134 moves vertically downward to a certain distance, the limiter 1341 will abut against the top of the bracket 11, thereby limiting the stroke of the pressing assembly 13. In this way, the stroke range limited by the limiter 1341 can be adjusted according to actual production needs, making the pressing operation more convenient and accurate.

[0059] like Figure 1 and Figure 2 As shown, in this embodiment, the bracket 11 includes a vertical pole 114 and a fixed frame 115. The fixed frame 115 is provided with a through hole 1151 that fits with the vertical pole 114. One side of the through hole 1151 is open and extends to form a pair of side ears 1152. The side ears 1152 are provided with at least one locking bolt 1153.

[0060] In this way, the fixed frame 115 can be sleeved on the vertical pole 114 through the through hole 1151. Since there is an opening between the side ears 1152, the height position of the fixed frame 115 connected to the vertical pole 114 is adjustable. A pair of side ears 1152 are locked by locking bolts 1153, so that the opening spacing between the two side ears 1152 becomes smaller, and the fixed frame 115 is clamped on the vertical pole 114, thereby achieving the purpose of firmly locking the fixed frame 115 on the vertical pole 114.

[0061] like Figure 1 , Figure 3 and Figure 4 As shown, in this embodiment, the material of the first pressing rod 1321 and the second pressing rod 1322 is POM (Chinese name: polyoxymethylene). POM material has high strength and rigidity, good elasticity, good wear resistance, is not easy to be damaged, and is suitable for pressing operations.

[0062] like Figure 1 As shown, in this embodiment, a rubber sleeve 1111 is provided on the hand crank 111.

[0063] Specifically, the rubber sleeve 1111 is soft and can increase the friction when the hand grasps the hand crank 111, making it easy to hold. When performing the pressing operation, the hand is not likely to slip off the hand crank 111, thus facilitating the pressing operation.

[0064] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
