[0027] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] During paint spraying operations, a paint spray gun is usually used to spray paint. For this purpose, a container for holding paint needs to be installed on the spray gun, and the container usually includes a pot body, a pot cover and an adapter. The pot body and the pot cover are connected together to form a cavity for holding paint, and the cavity is used to output the paint in the cavity to the outside through the connecting pipe on the pot cover. At the same time, in order to assemble the pot body and the pot cover to the spray gun, the connecting pipe of the pot cover will be connected to the spray gun through the adapter.

[0029] like Figure 1-Figure 5As shown, this embodiment provides a pot cover for a spraying device, wherein the pot cover 2 is provided with a protruding connecting pipe 21, and at least one connecting portion 22 is provided on the outer tube wall of the connecting pipe 21, and the connecting portion 22 includes two first ribs 221 arranged side by side, and a protruding positioning rib 224 is further provided on the outer tube wall of the connecting pipe 21 between the two first ribs 221;

[0030] A slot 223 is formed between the two first ribs 221, and the slot 223 extends along the outer circumference of the connecting tube 21. The slot 223 is configured to insert a spiral wedge-shaped element formed by an external component, and the positioning rib 224 is configured to position the spiral wedge-shaped element after the spiral wedge-shaped element is inserted into the slot to prevent the spiral wedge-shaped element from escaping from the slot.

[0031] The extending direction of the first ribs 221 and the extending direction of the positioning ribs 224 are arranged in a staggered manner.

[0032] Specifically, in actual use, the pot cover 2 is assembled to the pot body 1 of the fluid storage, and paint is placed in the pot body 1. The fluid storage is assembled to the spray gun through the connecting pipe 21 provided on the pot cover 2.

[0033] In the case where the spray gun itself has a spiral wedge-shaped element, the spray gun is an external component. During the process of assembling the connecting pipe 21 set on the pot cover 2 to the spray gun, the connecting pipe 21 can be directly assembled on the spray gun with the spiral wedge-shaped element; or, the connecting pipe 21 can be assembled to the spray gun through an adapter with a spiral wedge-shaped element, that is, the adapter is an external component.

[0034] After the pot cover 2 is assembled to the external component through the connecting tube 21, the spiral wedge-shaped element on the external component can be inserted into the slot 223 formed between the two first ribs 221, and as the spiral wedge-shaped element continues to be inserted into the slot 223, the spiral wedge-shaped element will be stuck on the positioning rib 224 to complete the assembly.

[0035] During use, as the spray gun moves back and forth to spray paint, the spiral wedge-shaped element is restricted between the two first ribs 221, so that the first ribs 221 clamp the spiral wedge-shaped element to ensure a secure installation. In addition, the spiral wedge-shaped element will alternately apply external force to the two first ribs 221, and the two first ribs 221 are used to withstand the impact force generated by the spiral wedge-shaped element during use, thereby reducing the damage of the first ribs 221 and improving the reliability of use.

[0036] In addition, for the spiral wedge-shaped element, after it is inserted into the slot 223 and assembled in place, it is further positioned by the positioning ribs 224, thereby effectively preventing the spiral wedge-shaped element from escaping from the slot 223.

[0037] Furthermore, the connecting portion 22 further includes a second rib 222 , and the second rib 222 is connected to the ends of the two first ribs 221 , and the two first ribs 221 and the second rib 222 form a sideways U-shaped structure.

[0038] Specifically, since the two first ribs 221 are connected by the second rib 222, when a single first rib 221 and the spiral wedge-shaped element abut against each other, the force is transmitted to the other first rib 221 through the second rib 222, so that the two first ribs 221 can jointly bear the force generated by the spiral wedge-shaped element. In this way, fatigue damage caused by frequent stress on a single rib on the connecting pipe 21 can be effectively reduced.

[0039] Furthermore, the end of the slot 223 away from the second rib 222 is an opening, and the opening is a trumpet-mouth structure.

[0040] Specifically, the opening of the slot 223 is in a trumpet-mouth structure, so that when the spiral wedge-shaped element is inserted into the slot 223, the trumpet-mouth structure enables the spiral wedge-shaped element to be smoothly inserted into the slot 223.

[0041] Furthermore, a filter screen 23 is provided on the inner wall of the pot cover 2 , and the filter screen 23 covers the pipe opening of the connecting pipe 21 on the inner wall of the pot cover 2 .

[0042] Specifically, in order to protect the spray gun, the paint contained in the kettle body 1 may be mixed with impurities. Therefore, a filter net 23 is provided on the kettle cover 2 to filter the paint flowing into the connecting pipe 21 by the filter net 23, thereby filtering out impurities in the paint.

[0043] In one embodiment, in order to facilitate operators to replace the filter screen 23 and prolong the service life of the kettle cover 2, a plurality of protruding claws 24 are provided on the inner wall of the kettle cover 2, and the filter screen 23 is clamped between the plurality of claws 24.

[0044] Specifically, the plurality of claws 24 formed on the inner wall of the pot cover 2 can clamp and limit the filter 23 so that the filter 23 is assembled to the inner wall of the pot cover 2 to cover the connecting pipe 21 from one side of the inner wall of the pot cover 2 .

[0045] In another embodiment of the present application, the utility model further provides a fluid storage device, including a kettle body 1, and also including a kettle cover 2 for the spraying device in the above embodiment, wherein the kettle cover 2 for the spraying device is detachably arranged on the kettle body 1.

[0046] Furthermore, a through hole 11 is provided at the bottom of the kettle body 1 , and a detachable plug 12 is provided on the through hole 11 .

[0047] Specifically, during the process of spraying paint with a spray gun, as the amount of paint used in the kettle body 1 gradually decreases, in order to balance the pressure in the kettle body 1, a through hole 11 is set at the bottom of the kettle body 1 to meet the requirement of ventilation and balanced air pressure, and a detachable plug 12 is set on the through hole 11 to block the through hole 11 with the plug 12 when not in use to prevent paint from leaking.

[0048] In order to facilitate use and avoid the plug 12 from being lost, a connecting piece 13 is provided on the plug 12 , and the end of the connecting piece 13 is arranged on the bottom of the kettle body 1 .

[0049] Specifically, the connector 13 can be an integral structure with the plug 12 or designed separately from the plug 12 and connected for use. The connector 13 is a flexible structure. For example, the connector 13 and the plug 12 are both made of materials such as rubber or silicone to facilitate operation by operators.

[0050] like Figure 6 As shown, the fluid storage device also includes an adapter 3, on which a spiral wedge-shaped element 31 is provided. The adapter 3 is sleeved on the connecting pipe of the spray pot cover 2, and the spiral wedge-shaped element 31 is inserted into the slot of the spray pot cover and stuck on the positioning rib.

[0051] Compared with the prior art, the advantages and positive effects of the utility model are: a connecting part is provided on the connecting tube of the kettle cover, and a slot is formed between two first ribs configured on the connecting part to meet the insertion requirements of the spiral wedge-shaped element formed by the external component; after the spiral wedge-shaped element is inserted into the slot, the spiral wedge-shaped element will be clamped between the two first ribs, so that during use, the spiral wedge-shaped element will alternately apply force to the two first ribs, and the two first ribs are used to clamp the spiral wedge-shaped element. On the one hand, the force generated by the spiral wedge element can be borne by the two first ribs to improve the reliability of use; on the other hand, the two first ribs can effectively fix the spiral wedge-shaped element and cooperate with the positioning ribs to position the spiral wedge element, thereby improving the reliability of the connection.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
