Detailed description of the invention
Illustrate that the invention will be further described with detailed description of the invention below in conjunction with accompanying drawing:
A kind of self-locking type spray lid as shown in Figure 1 to 9, includes base 1, described base 1 is connected with head 2, described head 2 is provided with nozzle 3, be provided with the head lockout mechanism 4 that head 2 can be stoped to press down movement between base 1 and head 2.
As shown in Figures 2 and 3, the lockout mechanism of head described in the present invention 4 includes the locating piece 41 arranged to downward-extension in head 2, between described head 2 and base 1, be provided with lock ring 42 be provided with to push up on described lock ring 42 inwall and be pressed in described locating piece 41 lower end thus stop head 2 to press down the dead bolt 43 of movement, described base 1 is provided with position-limited trough 44, and described dead bolt 43 is arranged in described position-limited trough 44.In use, when head lockout mechanism 4 is in released state, described locating piece 41 is separated from each other with dead bolt 43 this practical self-locking type spray lid, and head 2 can produce under external force and press down movement.When head lockout mechanism 4 is in locking state, top, described locating piece 41 lower surface is pressed on the upper surface of described dead bolt 43.Now, due to the obstruction of dead bolt 43, can not produce press down movement even if head 2 is subject to external force.
As shown in Figure 5, the present invention is provided with and head lockout mechanism 4 can be prevented with the limiting mechanism 5 being intended to change between locking state and released state on described base 1.Arrange in the present invention limiting mechanism 5 effectively ensure that rotating spraying covers can not because of collision or other maloperation and produce unnecessary trouble in use or transportation.
Limiting mechanism 5 described in the present invention comprise be arranged on described base 1 upper end and can prevent dead bolt 43 from changing from locking state to released state first restriction projection 51, also be provided with the second restriction projection 52 that can prevent dead bolt 43 from changing from released state to locking state in described base 1 upper end, described dead bolt 43 end is provided with the elastic portion 431 crossing described first restriction projection 51 or the second restriction projection 52 when firmly rotating lock ring 42.In the present invention when head lockout mechanism 4 is in locking state, the cell wall and first that the elastic portion 431 of described dead bolt 43 is in position-limited trough 44 left side limits between projection 51, like this under the restriction of the first restriction projection 51, dead bolt 43 can not move easily on the right of position-limited trough 44, thus play the effect of locking head, when rotating spraying lid is adjusted to released state by needs, only need firmly to rotate lock ring 42, under the effect of certain external force, elastic portion 431 on dead bolt 43 end can cross the first restriction projection 51, then continue to rotate lock ring 42 and just head 2 can be adjusted to released state from locking state.When lock ring 42 rotates to certain position, elastic portion 431 on dead bolt 43 end will collide the second restriction projection 52, now apply certain external force, elastic portion 431 on dead bolt 43 end crosses the second restriction projection 52, dead bolt 43 is just limited between the cell wall on the right of the second restriction projection 52 and position-limited trough 44, thus plays the effect of locking dead bolt 43.
As shown in Fig. 2,4 and 7, outer bulge loop 6 is provided with in described base 1 upper end in the present invention, ring-shaped step 7 is formed between described outer bulge loop 6 and base 1 edge, described lock ring 42 is set on outer bulge loop 6, top, described lock ring 42 bottom is pressed on described ring-shaped step 7, described position-limited trough 44 is arranged on described outer bulge loop 6, described outer bulge loop 6 upper end outer wall is provided with connecting groove 61, described head 2 lower end inner wall is provided with and connects raised line 201, described connection raised line 201 is fastened in described connecting groove 61.Head 2 of the present invention is fastened and connected with connecting groove 61 by being connected raised line 201 mutually with base 1, installs, dismantles simply, convenient.The thickness of lock ring 42 described in the present invention is suitable with the degree of depth of ring-shaped step 7, and when lock ring 42 is set in after on outer bulge loop 6, the outer wall of described lock ring 42 is concordant with the outer wall of base 1 lower end, compact conformation of the present invention, appearance looks elegant.
As shown in Fig. 4,5 and 7, be provided with positioning groove 62 in the present invention in described outer bulge loop 6 upper end, the position that described head 2 is corresponding with positioning groove 62 is provided with locating convex block 202, and when head 1 is connected with base 1, described locating convex block 202 is arranged in positioning groove 62.Two positioning grooves 62 are symmetrically arranged with in described outer bulge loop 6 upper end in the present invention, correspondingly, the position that head 2 is corresponding with positioning groove 62 is provided with two locating convex blocks 202, by coordinating of positioning groove 62 and locating convex block 202, effectively define the position between locating piece 41 and position-limited trough 44, effectively prevent locating piece 41 in use procedure from producing because head 2 or base 1 rotate and depart from thus the thing causing head lockout mechanism 4 to lose efficacy generation.
As shown in Figure 6 and 9, in the present invention described locating piece 41 to lock along head lockout mechanism 4 direction side on be provided with transition circle cambered surface 411.When rotating spraying lid needs to lock, rotate lock ring 42, dead bolt 43 runs into locating piece 41, and under the effect of external force, dead bolt 43 is cut by transition circle cambered surface 411 and is easy to enter bottom locating piece 41, thus realizes locking, and makes the process of locking become very smooth.
As Fig. 1,4,5, shown in 6 and 8, on described lock ring 42 outer wall, in the present invention, be provided with the convenient non-slip bumps 421 rotating lock ring 42.Described non-slip bumps 421 is symmetricly set on lock ring 42, can be made up of multiple little anti-skidding raised line.
Head 2 described in the present invention includes head body 21, described head body 21 upper end is provided with pressing cambered surface 22, coupling link 24 is connected with by dowel 23 in described head body 21 lower end, described connection raised line 201 is arranged on described coupling link 24 inwall, and described locating convex block 202 is arranged on described coupling link 24 end face.On described head body 21 upper end, be provided with pressing cambered surface 22 in the present invention makes pressing more comfortable.
Opening 8 is provided with in described base 1 upper end in the present invention, the base 1 of described opening 8 surrounding is provided with internal projecting ring 9, described nozzle 3 includes and is arranged on described head 2 connection pipe 31 vertically downward, in described head 2, be provided with the passage 32 be connected with described connection pipe 31, described head 2 is provided with the jet hole 33 be connected with described passage 32.
More than show and describe groundwork of the present invention and principal character and advantage of the present invention.The technical personnel of the industry should be understood; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification sheets just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
