DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] like Figures 1-9The spray cap with a locking function shown is used on a spray container bottle, including a bottom cover 1, a middle sleeve 2 and a top cover 3. The bottom cover 1 is provided with an accessory cavity 11, the accessory cavity 11 is used to install the middle sleeve 2, and the middle sleeve 2 is rotatably installed in the accessory cavity 11. The bottom cover 1 is snap-connected with the middle sleeve 2. The middle sleeve 2 can only rotate but cannot move up and down. The top cover 3 is vertically inserted into the middle sleeve 2. The pump head is subsequently installed inside the top cover 3. By applying force to the top cover 3, the pump head can be pressed. Therefore, the top cover 3 needs to be able to move vertically up and down relative to the middle sleeve 2. Since the top cover 3 and the middle sleeve 2 are plug-in Therefore, applying force to rotate the top cover 3 can drive the rotation of the middle sleeve 2. The first locking post 13 and the second locking post 14 are upright installed in the accessory cavity 11. The first locking post 13 and the second locking post 14 do not affect the lifting and lowering movement of the top cover 3 in the initial installation state. However, after the top cover 3 rotates, the first locking post 13 and the second locking post 14 can form a downward barrier for the top cover 3, and the top cover 3 loses its downward function and cannot squeeze the pump head. At this time, even if the top cover 3 is applied with force by mistake, liquid will not be discharged, which solves the problem of misoperation of the bottle cap very well.

[0028] like Figure 2 As shown, a plurality of evenly distributed arc-shaped ridges 12 are provided on the inner wall of the accessory cavity 11. Figure 3 As shown, an annular groove 21 is provided on the outer wall of the middle sleeve 2. Figure 9 As shown, when the middle sleeve 2 and the bottom cover 1 are assembled, the arc-shaped ridge 12 can be matched and snapped into the annular groove 21 to form a snap connection effect. The existence of the arc-shaped ridge 12 can only limit the lifting and lowering movement of the middle sleeve 2 relative to the bottom cover 1, but cannot limit the rotation of the middle sleeve 2. Therefore, the middle sleeve 2 has the function of rotation.

[0029] like Figure 2 As shown, the first locking post 13 and the second locking post 14 are symmetrically installed, and a positioning slot 131 is provided on the first locking post 13. Figure 3 As shown, the inner wall of the middle sleeve 2 is provided with a positioning ridge 22. Figure 8 As shown, the positioning ridge 22 can be matched and installed in the positioning slot 131. The middle sleeve 2 has the positioning and installation requirements in normal use (in order to make the top cover 3 match the first locking column 13 and the second locking column 14, which will be explained later). Therefore, the middle sleeve 2 is positioned and connected to the bottom cover 1 through the cooperation of the positioning ridge 22 and the positioning slot 131. The side edges of the positioning ridge 22 and the side edges of the positioning slot 131 are both provided with an arc wrap angle 221. Under this design, the positioning ridge 22 can slide out of the positioning slot 131. Sliding out requires applying a certain rotational force to the middle sleeve 2. This can prevent the middle sleeve 2 and the top cover 3 from being accidentally rotated and locked during normal use.

[0030] like Figure 3 As shown, the inner wall of the middle sleeve 2 is provided with a first lifting slot 23 and a second lifting slot 24, and the first lifting slot 23 and the second lifting slot 24 are symmetrically arranged. Figure 4 and Figure 5 As shown, the outer wall of the top cover 3 is provided with a symmetrical first guide protrusion 31 and a second guide protrusion 32. The first guide protrusion 31 corresponds to the first lifting slot 23 for insertion, and the second guide protrusion 32 corresponds to the second lifting slot 24 for insertion. Figure 8 As shown, the first guide protrusion 31 and the second guide protrusion 32 serve as movement guides for the top cover 3, so that the top cover 3 can perform vertical lifting and lowering movements relative to the middle sleeve 2. At the same time, the presence of the first guide protrusion 31 and the second guide protrusion 32 enables the force applied to the top cover 3 to drive the middle sleeve 2 to rotate together. The middle sleeve 2 is designed mainly to accommodate the top cover 3.

[0031] like Figure 3 As shown, the second lifting slot 24 is a through slot, and the movement of the second guide protrusion 32 is not restricted. A limiting protrusion 231 is provided on the top of the first lifting slot 23, and a cross block 311 is provided on the first guide protrusion 31. The limiting protrusion 231 blocks the rising path of the cross block 311. The cross block 311 rises with the first guide protrusion 31. When the cross block 311 contacts the limiting protrusion 231, the top cover 3 can no longer rise, and the top cover 3 reaches the maximum rising limit.

[0032] like Figure 4 and Figure 5 As shown, a first lifting notch 33, a second lifting notch 34 and a rotation notch 35 are provided on the side wall of the top cover 3. The first lifting notch 33 is opened to match the first locking post 13, and the second lifting notch 34 is opened to match the second locking post 14. When the top cover 3 is in normal use, the first lifting notch 33 needs to correspond to the position of the first locking post 13, and the second lifting notch 34 needs to correspond to the position of the second locking post 14. In this way, after the top cover 3 is lowered, the first locking post 13 can be inserted into the first lifting notch 33, and the second locking post 14 can be inserted into the second lifting notch 34. At this time, the top cover 3 can be raised and lowered, and has a press-to-use function. The positioning of the top cover 3 is achieved by relying on the positioning ridges 22 on the inner wall of the aforementioned middle sleeve 2. Figure 8 and Figure 9 As shown, when the positioning protrusion 22 is matched and installed in the positioning slot 131, the first lifting notch 33 corresponds exactly to the position of the first locking column 13, and the second lifting notch 34 corresponds exactly to the position of the second locking column 14. Figure 5 and Figure 6 As shown, the rotation notch 35 is located at the bottom of the outer wall of the top cover 3, and the side wall of the top cover 3 where the rotation notch 35 is opened becomes shorter, so it is set as a short side wall 36. Figure 8As shown, the first locking column 13 is partially separated from the first lifting gap 33 after the top cover 3 is lifted, the short side wall 36 is higher than the top of the first locking column 13, and the first locking column 13 can move in the rotating gap 35 under the condition of rotating the top cover 3, the length of the rotating gap 35 determines the rotating angle of the top cover 3, at this time, the first locking column 13 moves below the short side wall 36, and the first locking column 13 forms a blocking downward effect on the short side wall 36, as shown in Figure 9 As shown, the part of the side wall of the top cover 3 which is not provided with the rotating gap 35 is a long side wall 37, the second locking column 14 is completely separated from the second lifting gap 34 after the top cover 3 is lifted, and the second locking column 14 moves below the long side wall 37 under the condition of rotating the top cover 3, the second locking column 14 does not affect the rotation of the top cover 3 and the middle sleeve 2, but the second locking column 14 forms a blocking downward effect on the long side wall 37, and since the long side wall 37 and the short side wall 36 of the top cover 3 are both blocked downward, the top cover 3 cannot be lowered at this time, even if the top cover 3 is pressed by mistake, the pump head will not be squeezed, and liquid will not be discharged, thus the problem of mistaken operation and liquid discharge is solved, the design makes the utility model have a large difference from the existing products, the user has a better use feeling, and the product has core market competitiveness.

[0033] The use mode of the utility model is rotating locking and reverse rotating unlocking again.

[0034] As shown in the drawings, Figure 2 As shown, a plurality of convex points 15 are uniformly arranged on the inner wall of the accessory cavity 11, the convex points 15 are in contact with the outer wall of the middle sleeve 2, and the convex points 15 can increase the rotating friction of the middle sleeve 2, and bring a good movement feeling to the rotating movement of the middle sleeve 2 and the top cover 3.

[0035] As shown in the drawings, Figure 1 As shown, a plurality of straight stripes 16 are arranged on the outer wall of the bottom cover 1, the straight stripes 16 can improve the gripping friction of the bottom cover 1, so that the bottom cover 1 can be gripped tightly, and the rotating movement of the middle sleeve 2 and the top cover 3 can be better operated.

[0036] The preferred embodiments of the utility model are described above, the protection scope of the utility model is not limited to the above-mentioned embodiments only, and any technical scheme belonging to the idea of the utility model belongs to the protection scope of the utility model. It should be noted that, for ordinary technical personnel in the technical field, some improvements and decorations without departing from the principle of the utility model are also regarded as the protection scope of the utility model.
