[0019] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0020] Please see Figs. 1-3 This utility model provides a technical solution: a quick-disassembly plunger pump plunger device, including a toothed plate 1 and a one-way ejection mechanism 2. The one-way ejection mechanism 2 is disposed on the outer wall of the toothed plate 1. The one-way ejection mechanism 2 includes a hollow block 201, a rotating rod 202, a gear 203, a U-shaped plate 204, and an annular plate 207. The outer wall of the toothed plate 1 is provided with the hollow block 201, and the toothed plate 1 penetrates the interior of the hollow block 201. The annular plate 207 is fixedly installed on the top of the hollow block 201. The rotating rod 202 is fixedly installed on the inner walls of the front and rear sides of the annular plate 207. The outer wall of the rotating rod 202 is rotatably connected to the interior of the gear 203. Both ends of rod 202 pass through annular plate 207 and are rotatably connected to the front and rear inner walls of U-shaped plate 204 respectively. Gear 203 meshes with toothed plate 1. Limiting blocks 3 are rotatably installed on the front and rear inner walls of annular plate 207 through a second connecting rod. A set of second torsion springs 4 are fixedly installed on the front and rear sides of limiting blocks 3 respectively. One end of the two sets of second torsion springs 4 is fixedly connected to the front and rear inner walls of annular plate 207 respectively. One side of limiting block 3 extends to the teeth of gear 203. An auxiliary block 5 is fixedly installed at the bottom of toothed plate 1. A set of fixing rods 6 are fixedly installed on both sides of toothed plate 1 respectively. A support rod 7 is fixedly installed at the bottom of fixing rod 6.

[0021] Secondly, the one-way ejector mechanism 2 also includes a pointed insert 205, a first torsion spring 206, an annular plate 207, and an operating rod 208. The pointed insert 205 is rotatably mounted on the front and rear inner walls of the U-shaped plate 204 via a first connecting rod. The front and rear sides of the pointed insert 205 are respectively fixedly connected to one end of a set of first torsion springs 206, and the other ends of the two sets of first torsion springs 206 are respectively fixedly connected to the front and rear inner walls of the U-shaped plate 204. An ejector block 209 is fixedly mounted on the bottom of the hollow block 201, and an ejector rod is threadedly connected to one side of the ejector block 209. 210. An operating rod 208 is fixedly installed on the top of the U-shaped plate 204. The bottom of the pointed insert 205 extends to the teeth of the gear 203. Pulling the operating rod 208 moves the hollow block 201, which drives the top material block 209 and the top material rod 210 to push out the plunger. Only one person is needed to disassemble the plunger. The operation is simple and easy to learn. Disassembly is time-saving and labor-saving. It can also prevent workers from being pinched, making the device safer to use. Moreover, the device has a simple structure and low production and use costs, which improves the availability and practicality of the device.

[0022] Furthermore, a spherical rubber sleeve 8 is fixedly installed at one end of the operating lever 208, making it more comfortable for workers to hold the operating lever 208 to disassemble the plunger and preventing the edge of the operating lever 208 from hurting their hands.

[0023] Working principle: When using this device, place it between the connecting rod and the plunger, with the auxiliary block 5 pressing against the connecting rod, and then the ejector block 209 pressing against the plunger end. The operator holds the operating rod 208 through the spherical rubber sleeve 8 and pulls the operating rod 208 downward, causing the U-shaped plate 204 to rotate on the rotating rod 202. This causes the pointed insert 205 to push the gear 203 to rotate on the rotating rod 202. When the gear 203 rotates, it slides against the bottom of the limiting block 3, causing the limiting block 3 to rotate upward, so that the limiting block 3 slides out from between the teeth of the gear 203. Under the torque of the second torsion spring 4... When the gear 203 enters the next set of teeth, the meshing action between the gear 203 and the toothed plate 1 drives the hollow block 201 to move on the toothed plate 1. When the operating lever 208 is pulled upward, the pointed insert 205 will slide out from between the teeth of the gear 203. Since the limiting block 3 is still between the teeth of the gear 203, it plays a limiting role on the gear 203, which can prevent the gear 203 from rotating, so that the hollow block 201 can only move in one direction, driving the top material block 209 to push the plunger into the pump chamber. Then, the top material rod 210 is installed on the top material block 209. Continue to pull the operating lever up and down to apply force, and the top material rod 210 pushes the plunger out completely.

[0024] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
