Technical Field
The utility model relates to a water pump especially relates to a water pump convenient to assembly spiral cover.
Background
A screw cap with a smooth surface is assembled and disassembled on a water filling exhaust port of the existing water pump, and a hole site for tools such as a screw driver, a hexagonal opener and the like to operate is not arranged. When the screw cap is disassembled and assembled, the screw cap is easy to slip and low in operation efficiency. When the screw cap is clamped by using tools such as pliers, the screw cap is easily damaged.
Disclosure of Invention
An object of the utility model is to solve the above-mentioned problem that prior art exists and provide a water pump convenient to assemble spiral cover, set up the hole site that supplies instrument operations such as bottle opener, hexagonal opener on the spiral cover to set up not unidimensional hole section at same hole site, supply the instrument of different specifications to act on the spiral cover and carry out the dismouting, for improving dismouting efficiency greatly, and can not cause the destruction to the spiral cover.
The above technical purpose of the present invention is mainly solved by the following technical solutions: the water pump convenient for assembling the spiral cover comprises a water inlet, a water outlet and a water filling exhaust port, wherein the water filling exhaust port is provided with the spiral cover. The screw cap is provided with hole sites for tools such as a screwdriver and a hexagonal opener to operate, and hole sections with different sizes are arranged in the same hole site, so that tools with different specifications can act on the screw cap to be disassembled and assembled, the disassembling and assembling efficiency is greatly improved, and the screw cap cannot be damaged.
As further improvement and supplement to the above technical scheme, the utility model discloses a following technical measure:
in order to facilitate the operation of the hexagonal opener, the cross sections of the inner section hole and the outer section hole are both inner hexagons.
In order to facilitate the operation of the linear screwdriver, the cross sections of the inner section hole and the outer section hole are linear.
The outer cylindrical surface of the screw cap is provided with a plurality of anti-slip grooves or anti-slip convex strips which are circumferentially distributed by taking the axis of the screw cap as a symmetrical center line, and the anti-slip grooves or the anti-slip convex strips are axially arranged. When the spiral cover by the unscrewing under the effect of bottle opener, hexagonal opener, perhaps with the initial stage of spiral cover assembly with the pump body in the time, then can bare-handed action operate in the spiral cover, can improve operating efficiency, and the setting of spout or anti-skidding sand grip then prevents to skid, further improves operating efficiency.
In order to facilitate production and processing and demolding, the anti-slip grooves or the anti-slip raised strips extend to the outer end face of the screw cap, and an extension section with a certain length is formed on the outer end face.
In order to increase the strength, the inner end of the anti-skid groove or the anti-skid convex strip has a certain distance from the inner end surface of the screw cap.
The utility model discloses beneficial effect who has: 1. the screw cap is provided with hole sites for tools such as a screwdriver and a hexagonal opener to operate, and hole sections with different sizes are arranged in the same hole site, so that tools with different specifications can act on the screw cap to be disassembled and assembled, the disassembling and assembling efficiency is greatly improved, and the screw cap cannot be damaged. 2. When the spiral cover by the unscrewing under the effect of bottle opener, hexagonal opener, perhaps with the initial stage of spiral cover assembly with the pump body in the time, then can bare-handed action operate in the spiral cover, can improve operating efficiency, and the setting of spout or anti-skidding sand grip then prevents to skid, further improves operating efficiency. 3. In order to facilitate production and processing and demolding, the anti-slip grooves or the anti-slip raised strips extend to the outer end face of the screw cap, and an extension section with a certain length is formed on the outer end face. 4. In order to increase the strength, the inner end of the anti-skid groove or the anti-skid convex strip has a certain distance from the inner end surface of the screw cap.

Detailed Description
The technical solution of the present invention is further specifically described below by way of examples and with reference to the accompanying drawings.
Example (b): the water pump convenient for assembling the rotary cover comprises a water inlet 1, a water outlet 2 and an irrigation exhaust port 3, wherein the irrigation exhaust port is provided with the rotary cover 4, the outer end face of the rotary cover is provided with a tool operation hole 41, the operation hole at least comprises an inner section hole 41-1 and an outer section hole 41-2, and the cross section size of the inner section hole is smaller than that of the outer section hole. The screw cap is provided with hole sites for tools such as a screwdriver and a hexagonal opener to operate, and hole sections with different sizes are arranged in the same hole site, so that tools with different specifications can act on the screw cap to be disassembled and assembled, the disassembling and assembling efficiency is greatly improved, and the screw cap cannot be damaged.
As shown in fig. 2, the inner and outer holes have hexagonal cross sections for the convenience of the operation of the hexagonal opener.
As shown in fig. 3, in order to facilitate the operation of the linear driver, the cross sections of the inner section hole and the outer section hole are both linear.
The outer cylindrical surface of the screw cap is provided with a plurality of anti-slip grooves 41-3 or anti-slip convex strips (omitted for simplifying the space and avoiding the repeated description of the corresponding figures) which are circumferentially distributed by taking the axis of the screw cap as a symmetrical center line, and the anti-slip grooves or the anti-slip convex strips are axially arranged. When the spiral cover by the unscrewing under the effect of bottle opener, hexagonal opener, perhaps with the initial stage of spiral cover assembly with the pump body in the time, then can bare-handed action operate in the spiral cover, can improve operating efficiency, and the setting of spout or anti-skidding sand grip then prevents to skid, further improves operating efficiency.
In order to facilitate production and processing and demolding, the anti-slip grooves or the anti-slip raised strips extend to the outer end faces 41-31 of the screw cap, and extension sections with certain lengths are formed on the outer end faces.
In order to increase the strength, the inner end of the anti-skid groove or the anti-skid convex strip has a certain distance from the inner end surface of the screw cap.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention. In the above embodiments, the present invention may be variously modified and changed. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
