[0003] In existing technology, water intake tanks typically consist of a tank body and a cover mounted on top of the tank body. To ensure the vacuum level of the tank, the tank body and cover need to be tightly fixed. Therefore, a rotatable limiting rod is usually installed on the tank body, and a limiting groove is formed in the cover. The limiting rod is embedded in the limiting groove and then fixed with fasteners. Because the water intake area has a high moisture content and humidity, the limiting rod is prone to corrosion after being embedded in the limiting groove. The space between the limiting rod and the limiting groove can easily become blocked by rust, affecting the normal opening and closing of the cover. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a vacuum pump priming tank that can prevent rust from clogging the cover and affecting its opening and closing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a vacuum pump priming tank, comprising a tank body, a cover body installed on the tank body, a limiting groove formed on the cover body, a limiting rod rotatable and capable of being embedded in the limiting groove installed on the tank body, a fastener abutting against the cover body installed on the upper part of the limiting rod to connect the tank body and the cover body, a baffle plate installed in the limiting groove, the baffle plate comprising a contact plate and a locking plate, the cover body having a locking groove, the contact plate being placed in the limiting groove, and the locking plate being placed in the locking groove to fix the baffle plate to the cover body.

[0006] Furthermore, the baffle also includes a connecting portion that connects to the contact plate. The connecting portion extends into the slot and a limiting portion is connected to one end of the slot. The limiting portion is connected to the slot plate and forms a U-shaped structure.

[0007] Furthermore, the limiting part is embedded in the slot, and a limiting protrusion is provided on the side of the limiting part facing the slot, and the limiting part is provided with a groove into which the limiting protrusion is embedded.

[0008] Furthermore, the positioning plate includes a first plate and a second plate, and the positioning groove includes a first channel and a second channel. The first channel extends from the lower end of the cover to the upper end, and the second channel extends from the first channel to the upper end of the cover. The diameter of the first channel is larger than the diameter of the second channel. The first plate extends into the first channel, and the second plate extends into the second channel. The first plate and the limiting part form a U-shaped structure.

[0009] Furthermore, the card slot plate also includes a connecting plate, which connects the first plate body and the second plate body. An inclined surface is provided between the first channel and the second channel, and the connecting plate fits against the inclined surface.

[0010] Furthermore, the second channel is provided with a horizontally extending abutment at one end facing the upper surface of the cover, and the second plate is provided with an abutment that is inserted into the abutment.

[0011] Furthermore, the upper end face of the slot is provided with an extension extending toward the center, and the side of the extension facing the lower end face of the slot is provided with a plug-in groove, into which the contact plate is inserted.

[0012] In summary, this utility model has the following beneficial effects:

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] See Figures 1 to 5 This embodiment discloses a vacuum pump priming tank, including a tank body 100, a cover 200 installed on the top of the tank body 100, and a vacuum pump 400 connected to the bottom of the tank body 100. The cover 200 is connected to a water inlet pipe, which is connected to an external water source. The vacuum pump 400 can draw water from the external water source into the tank body 100.

[0022] To ensure the vacuum level inside the tank 100, good sealing performance is required between the tank 100 and the cover 200. Therefore, a limiting groove 210 is provided in the cover 200, and a limiting rod 300 that can be rotated and embedded in the limiting groove 210 is installed in the tank 100. A fastener 310 that abuts against the cover 200 is installed on the upper part of the limiting rod 300. The fastener 310 and the limiting rod 300 are threadedly engaged, thereby connecting the tank 100 and the cover 200 to ensure the sealing performance between the tank 100 and the cover 200.

[0023] A baffle 500 is installed inside the limiting groove 210. The baffle 500 includes a contact plate 510 and a locking plate 540. The contact plate 510 covers the side wall of the limiting groove 210. Meanwhile, a locking groove 220 is formed on one side of the limiting groove 210 on the cover 200. The locking plate 540 is embedded in the locking groove 220, thereby fixing the baffle 500 to the cover 200. The baffle 500 separates the limiting rod 300 from the side wall of the limiting groove 210, preventing corrosion between the limiting rod 300 and the side wall of the limiting groove 210, which would make it difficult for the limiting rod 300 to move out of the limiting groove 210, thus facilitating the opening and closing of the cover 200.

[0024] The baffle 500 also includes a connecting portion 520 that connects to the contact plate 510. The connecting portion 520 extends into the locking groove 220, and one end of the connecting portion 520 is connected to a limiting portion 530. The limiting portion 530 is connected to the locking plate 540 and forms a U-shaped structure. The baffle 500 is made of plastic and has good elasticity. Through the U-shaped structure, under the action of external force, the locking plate 540 can be moved closer to the limiting portion 530, and at the same time, it can be reset.

[0025] Specifically, the positioning plate 540 includes a first plate 541 and a second plate 543, and the positioning groove 220 includes a first channel 221 and a second channel 222. The first channel 221 extends from the lower end face of the cover 200 to the upper end face, and the second channel 222 extends from the first channel 221 to the upper end face of the cover 200. The diameter of the first channel 221 is larger than the diameter of the second channel 222. The first plate 541 extends into the first channel 221, and the second plate 543 extends into the second channel 222. The first plate 541 and the limiting part 530 form a U-shaped structure. When the positioning plate 540 is embedded in the positioning groove 220, the first plate 541 is in contact with the side wall of the first channel 221. The positioning plate 540 also includes a connecting plate 542, which connects the first plate 541 and the second plate 543. An inclined surface 223 is provided between the first channel 221 and the second channel 222, and the connecting plate 542 fits against the inclined surface 223. One end of the second channel 222 facing the upper surface of the cover 200 is provided with a horizontally extending abutment 224, and the second plate 543 is provided with an abutment 544 that inserts into the abutment 224. When the positioning plate 540 is embedded in the positioning groove 220, the abutment 544, in cooperation with the abutment 224, can fix the positioning plate 540 within the positioning groove 220, thereby ensuring the stability of the baffle 500. When the baffle 500 needs to be disassembled, manually press the U-shaped structure formed between the first plate 541 and the limiting part 530, so that the first plate 541 moves toward the limiting part 530, and at the same time, the second plate 543 and the abutment 544 move toward the side where the limiting part 530 is located, so that the abutment 544 can be removed from the abutment interface 224, and the locking plate 540 can be removed from the cover 200, thereby facilitating the cleaning and replacement of the baffle 500.

[0026] The limiting part 530 is embedded in the locking groove 220. A limiting protrusion 230 is provided on the side of the limiting part 530 facing the locking groove 220. The limiting part 530 has a groove 531 into which the limiting protrusion 230 is inserted. Through the cooperation between the groove 531 and the limiting protrusion 230, the stability of the connection between the limiting part 530 and the cover 200 can be ensured, and the limiting part 530 is prevented from falling out of the opening of the limiting groove 210.

[0027] The upper end face of the slot 220 is provided with an extension 211 extending toward the center. The side of the extension 211 facing the lower end face of the slot 220 is provided with a insertion groove 212. The contact plate 510 is inserted into the insertion groove 212, which can further ensure the stability of the baffle 500 fixed to the cover 200.
