Embodiment
The utility model is described in further detail below in conjunction with attached drawing embodiment.
Referring to Fig. 1~Fig. 6, it is a kind of with side row mouth grass trimmer housing, including housing 1, be opened on housing 1 side row
Mouthfuls 11, the seal closure 2 being covered on the row's mouth 11 of side, and seal closure 2 and housing 1 are compressed to the self-locking mechanism 3 of locking.
Wherein, housing 1 includes roof 12 and the side wall 13 from the bending extension of 12 edge of roof, above-mentioned side row's mouth 11
It is opened on side wall 13, for being discharged when grass trimmer is needed from side Lysimachia sikokiana for broken grass.
Seal closure 2 is covered on the row's mouth 11 of side, and the shape and size of seal closure 2 are adapted to side row's mouth 11, and seal closure 2 has
There are opposite first end 21 (in the present embodiment, being upper end) and second end 22 (in the present embodiment, being lower end), seal closure 2
First end 21 be rotatably connected to by shaft on housing 1 and arrange the adjacent position of mouth 11 with side, and set in junction
There is torsional spring 23, under the action of torsional spring 23, seal closure 2 keeps being bonded with housing 1.
In order to avoid seal closure 2, unexpectedly from side, row's mouth 11 is opened, therefore the second end 22 of seal closure 2 is provided with self-locking
Mechanism 3.Self-locking mechanism 3 is arranged on position adjacent with side row's mouth 11 on housing 1, and corresponding to the second end 22 of seal closure 2.
Self-locking mechanism 3 includes bottom plate 31, movable part 32, limited block 33 and the spring 34 that fixation is installed with the side wall 13 of housing 1, entirely
Only 32 part of movable part of self-locking mechanism 3 interacts with seal closure 2.Wherein, screw pole 333 is may be provided with limited block 33, is limited
Position block 33, bottom plate 31 can be installed by the side wall 13 of screw and housing 1 and fixed, and bottom plate 31 is between limited block 33 and housing 1.
The one side of limited block 33 towards 2 first end 21 of seal closure is formed as stop surface 331, and limiting card is offered in stop surface 331
Mouth 332, movable part 32 keep extending the trend outside limited block 33 by spacing bayonet 332 out of limited block 33.Stop surface
331 define the relative position of the activity of 32 relative limit block of movable part 33.For ease of the installation of movable part 32,33 direction of limited block
The side of bottom plate 31 is in open-like shape.
Movable part 32 includes movable part main body 321, and is formed on the opposite side of movable part main body 321 at least two
The first limit protrusion 322, bottom plate 31 towards limited block 33 one side formed with the 3rd limit protrusion 311.Two opposite sides
First limit protrusion 322 in face is used to coordinate with limited block 33.Movable part main body 321 towards on the side of bottom plate 31 formed with
Two limit protrusions 323, coordinate with the 3rd limit protrusion 311.One end of spring 34 is located at the end in limited block 33 with movable part 32
Portion abut, the other end abutted with the inside of limited block 33 so that movable part 32 keep reaching from spacing bayonet 332 it is spacing
Trend outside block 33.
When self-locking mechanism 3 is installed, movable part 32 is inserted into from the open side of limited block 33, opposite two the first limit convexes
Play 322 to be connected to stop surface 331 respectively and be located inside 332 both sides of spacing bayonet, spring 34 is inserted into limited block 33, is made
The one end for obtaining spring 34 abuts with movable part 32, is abutted inside the side that the other end is opposite with stop surface 331 with limited block 33,
Spring 34 is so that movable part 32 keeps stretching out the trend outside limit opening 332；Hereafter, limited block 33 and bottom plate 31 are installed, bottom
3rd limit protrusion 311 of plate 31 is abutted with the second limit protrusion 323 of movable part 32, stop surface 331, the second limit convex
Play 311 pair of first limit protrusion 322 and apply unidirectional power (in the present embodiment, referring to Fig. 3, stop surface the 331, the 3rd
Limit protrusion 311 is all located at the first limit protrusion 322, the top of the second limit protrusion 323, and the first limit protrusion 322, second is limited
Position protrusion 323, which applies, holds down the power in limited block 33), thus, define the pole that movable part 32 is stretched out outside limited block 33
Extreme position, avoids 32 relative limit block 33 of movable part from rotating out of outside limited block 33.When self-locking mechanism 3 and housing 1 are completed to install,
Self-locking mechanism 3 is in self-locking state, and movable part 32 extends the part of limited block 33 and abutted with the second end 22 of seal closure 2, will
The second end 22 of seal closure 2 is compressed to side row's mouth 11, keeps side row's mouth 11 to close.
When needing opening side to arrange mouth 11, movable part 32 is pressed to the direction inside limited block 33 so that movable part 32
No longer abutted with seal closure 2, referring to Fig. 5, self-locking mechanism 3 unlocks, and thus can arrange the second end 22 of seal closure 2 to away from side
The direction of mouth 11 rotates, and opening side row's mouth 11, in the process, spring 34 is compressed；When unclamping movable part 32, spring 34
Restoring force causes movable part 32 to 33 external reset of limited block, referring to Fig. 6.
When needing to be again switched off side row's mouth 11, likewise, movable part 32 is pressed to the direction inside limited block 33, this
When the second end 22 of seal closure 2 can be rotated to side Pai Kou11 directions, until closed side row mouth 11, in the process, spring 34
Compressed, when row's mouth 11 completely closes when side, unclamp movable part 32, the restoring force of spring 34 causes movable part 32 to limited block 33
External reset, movable part 32 are abutted with seal closure 2 again, and self-locking mechanism 3 comes back to self-locking state, and side row's mouth 11 is pinned
(seal closure 2 is pinned with housing 1).
