Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Embodiment 1
As shown in Figure 1 to Figure 2, a kind of antirust adjustment arm, including shell 1, mounting hole 2, worm gear 3, worm screw 4, hollow cavity 5,
On 1 top of shell, the worm gear 3 is arranged in 1 bottom middle position of shell, 3 upper end of worm gear and snail for the setting of mounting hole 2
Bar 4 engages, and the hollow cavity 5 is located at 3 top of worm gear, and the worm screw 4 is inserted into hollow cavity 5, and the sealing of 5 one end of hollow cavity is another
End is opening, and 5 opening of hollow cavity is equipped with protection cap 6, and protection cap 6 is rectangular parallelepiped structure, and protection cap 6 is close to shell 1
It is on one side opening, for hex bolts lid, fixing bolt 10 etc. to be frequently necessary to adjust, and and is easy to make wet in air
The part position that gas, dust enter is wrapped up into protection cap 6, and the one end in the opening of protection cap 6 face and shell 1 are side walls hinged, another
End is equipped with bond, such as lock or magnet, to guarantee that protection cap 6 can arbitrarily play open and close on the side wall of shell 1
It closing, is equipped with protecting bin 7 in the protection cap 6, protecting bin 7 is provided with desiccant, for guaranteeing the environmental drying in protection cap 6,
Protecting bin 7 is set on the inner sidewall of protection cap 6, is preferably set in that maximum one side wall of 6 area of protection cap, protecting bin 7 exists
Volume in protection cap 6 should not be too large, and otherwise can make protecting bin 7 that can not accommodate the components for needing protection dry and therefore be
Realize that protecting bin 7 keeps the maximization of dry effect, is disposed at the maximum one side of 6 inner sidewall of protection cap as far as possible
On, by increasing the diameter on 7 surface of protecting bin, reduce the height of protecting bin 7, to realize the volume of protecting bin 7 to the full extent
Maximize, allow to it is as much as possible be put into desiccant, the protecting bin 7 includes the toroidal cavity and warehouse lid of protrusion, institute
Stating warehouse lid is bottle cap shape, and circular surface portion is reticular structure, and convenient and dry machine plays effect, and warehouse lid and groove screw thread connect
It connects, it is convenient that desiccant is replaced, it is also beneficial to make to connect between warehouse lid and recessed grain even closer, the worm screw 4 is separate
One section of hollow cavity 5 is equipped with hexagonal and adjusts bolted cover 8, and hexagonal adjusts the part that bolted cover 8 is contacted with hollow cavity 5 and is equipped with rubber pad
9, hexagonal, which adjusts bolted cover 8, makes that worm screw 4 is adjusted for convenience, and the purpose of rubber pad 9 is to guarantee that hexagonal adjusts spiral shell
When stopper 8 is adjusted, it will not be ensure that the air-tightness between hex bolts lid and worm screw 4 and cavity by being flowed into gap, be prevented
Arm internal rust is only adjusted, further includes fixing bolt 10, fixing bolt 10 is for blocking worm gear 3, the fixing bolt 10
And hexagonal adjusts bottom between bolted cover 8 and is equipped with one layer of water-absorbing sponge pad 11, is further ensured that and is adjusting fixing bolt 10 and snail
When bar 4, even if still there is the clammy air in part to be flowed into inside adjustment arm from the gap of fixing bolt 10 and worm screw 4,
On moisture can also be siphoned away by the water-absorbing sponge pad 11 by gap, guarantee the drying of air, water-absorbing sponge pads 11 mating protection lids 6
In protecting bin 7, can further be promoted adjustment arm drying effect, the worm screw 4 go deep into hollow cavity 5 one end be equipped with tense
Spring 12 is connected with the side wall in hollow cavity 5, and the purpose of setting back-moving spring 12 is in order to since the factors such as vibration lead to worm screw
4 deviate outward, cause there are partial air inflow before amendment, and spring can guarantee when hexagonal adjusts bolted cover 8 and loosens, snail
Bar 4 will not deviate outward, and the butter mouth 13 being used cooperatively through shell 1 and worm gear 3 is equipped on the right side of 1 bottom end of shell, is passed through
Butter mouth 13 lubricates adjustment arm, achievees the effect that antirust dedusting, protection adjustment arm.The working principle of the present embodiment is:
When adjustment arm needs to adjust, the fastener in protection cap 6 is first opened, protection cap 6 is opened, passed through hexagonal and adjust bolted cover 8
