Abstract
The utility model relates to a screw nut for a water spraying gun. The utility model is designed for increasing safety. The utility model is provided with a screw nut body, the center of the body is provided with an internal screw-thread cavity. The utility model is characterized in that the screw nut body is formed by plastic injection molding, and the outer surface of the screw nut body is uniformly distributed with a plurality of friction arc-shaped grooves along the periphery.
Description
The utility model relates to water pistol, especially is used for the nut technical field that spanner and sealing push rod are located by connecting on the water pistol.
Water pistol often by people be used for water spray pouring flowers and trees gardens, beautify the environment.Common water gun structure is that water pistol sealing push rod is that jack type is connected with spanner, lives usually with the nut positioning and fixing at the sealing putting back-end then and adopts metal to be made of such as copper with nut, and its outer surface rolls and is carved with fricting strip.Its shortcoming is: the metal nut quality is harder, when people firmly turn nut, usually can fray watch face skin; especially child cause certain injury easily, and metal material is somewhat expensive; raw materials for production cost height, the finished surface fricting strip needs annular knurl technology again, and production technology is easy inadequately.
The purpose of this utility model is to provide a kind of water pistol upper cap nut that can not fray people's gesture and facial expression skin, comparison safety easily, produce easily again.
The technical solution of the utility model is achieved in that this water pistol upper cap nut, it has a nut body, the body center is shaped on the internal thread chamber, it is characterized in that the nut body adopts plastic injection-mouldedly to form and be uniformly distributed with many friction arc grooves along the circumference at this external surface of nut.
Above-mentioned nut body is that the center has the gap annular chamber along the internal thread chamber, is provided with cross between the annular cavity wall of gap and strengthens gusset.
Above-mentioned this external surface of nut front and rear portions position is the inclined-plane.
Nut of the present utility model adopts plastic injection-moulded forming, and outer surface is opened the friction groove, because the plastics quality does not have metallic hard, and arc groove, transition is slick and sly, generally can not fray people's watch face, and security is good, the raw materials for production cost is low, can one-shot forming form, and production technology is easy.Between the annular cavity wall of gap cross is set and strengthens gusset, both guaranteed certain structural strength, can alleviate nut weight again and reduce this external surface of raw materials for production nut front and rear portions position is inclined design, increases frictional force thereby make the part groove more press close to staff.
Description of drawings:
Fig. 1 the utility model nut schematic appearance;
Fig. 2 the utility model nut complete section figure;
Fig. 3 the utility model nut vertical view.
Below in conjunction with description of drawings embodiment of the present utility model is further described:
As shown in the figure, this water pistol upper cap nut has a nut body 1, and the body center is shaped on internal thread chamber 2, and its internal thread cooperates with sealing putting back-end portion external screw thread, and this external surface of nut is uniformly distributed with many friction arc grooves 5 along the circumference.With the internal thread chamber is the center, and the nut body also has gap annular chamber 3, between the annular cavity wall of gap cross is set and strengthens gusset 4, and this external surface of nut front and rear portions position is inclined- plane 6,7, and whole nut can adopt injection molding to form.
Claims (3)
1. water pistol upper cap nut, it has a nut body (1), and the body center is shaped on internal thread chamber (2), it is characterized in that the nut body adopts plastic injection-mouldedly to form and be uniformly distributed with many friction arc grooves 5 along the circumference at this external surface of nut.
