Quantity it is more fewer better.
Invention content
Goal of the invention：Purpose of the present invention is to be based on cam mechanism principle, table class product two zero can be realized by providing one kind
It is limited between part, the cam-type sealed knob mechanism of locking and lead sealing.
Technical solution：The present invention includes the sealed knob mounted on upper cover, and the sealed knob is by end cap and multi-diameter shaft
Composition, end cap are located at upper outer side of lid, and ladder shaft portion is located on the inside of upper cover, and the multi-diameter shaft is equipped with open slot, for connecting
The boss on the inside of lower cover is connect, the end face of the open slot is step-like, and the end cap is all provided with in the outer circle of upper cover mounting hole
There are two through-hole radially, the through-hole is inserted into lead sealing.
It is radially equipped with one section of protrusion on the end cap of the sealed knob, can match with the card slot on upper cover mounting hole
It closes, and is rotated in card slot.
The front of the sealed knob end cap is equipped with cross recess, is operated convenient for screwdriver.
The mounting hole of the upper cover is equipped with the matched card slot of protrusion with sealed knob end cap, the termination of the card slot
Position is located at vertical direction, the rotation angle for controlling sealed knob.
The cross section curve of the open slot uses cam-type asymptote, it can be achieved that connecting, limiting with lower cover boss and gradual
The function of locking.
The upper cover is U-shaped cover board with lower cover, and lower lid is equipped with the U-type groove being connect with upper cover.
Advantageous effect：The cam-type sealed knob mechanism of the present invention can pass through mold design as table class product
It realizes, the high-volume of good cooperation table class product quickly produces, and supplies the problems such as short without part, in addition, this
Invention may be implemented to exempt from screw installation, reduces assembly process and assembly difficulty, effectively reduces cost of labor, adapt to multiple tear open
Occasion is unloaded, easy to use, securely and reliably, shape simple and beautiful has preferable popularizing value in ammeter class industry.

Specific implementation mode
The invention will be further described below in conjunction with the accompanying drawings.
As shown in Figures 1 to 7, the present invention includes upper cover 1, sealed knob 2, lead sealing 3 and lower cover 4.Upper cover 1 is U with lower cover 4
Type cover board, lower cover 4 are equipped with the U-type groove being connect with upper cover 1.The mounting hole of upper cover 1 is for installing sealed knob 2, sealed knob 2
It is made of end cap and multi-diameter shaft, when installation, end cap is located at the outside of upper cover 1, and ladder shaft portion is located at 1 inside of upper cover.
As shown in Fig. 2, on the end cap of sealed knob 2 radially be equipped with one section of protrusion, can on 1 mounting hole of upper cover
Card slot cooperation, and rotated in card slot, the front of end cap is equipped with cross recess, is operated convenient for screwdriver, the final position of card slot
Positioned at vertical direction, the rotation angle for controlling sealed knob 2；Multi-diameter shaft is equipped with open slot, the cross section curve of open slot
Using cam-type asymptote, the end face of the boss for connecting 4 inside of lower cover, open slot is step-like, and end cap is installed with upper cover 1
It is all provided in the outer circle in hole there are two through-hole radially, two through-holes are located at same straight line, for being inserted into lead sealing 3.
As shown in figure 3, the card slot of upper cover 1 is designed as circle ring, the initial of the rotation of sealed knob 2 is devised in annulus
Position and final position, sealed knob 2 can rotate between the initial position and final position in the annulus, the termination of card slot
Position is located at vertical direction.As shown in figure 4, lower cover 4 and 2 junction of sealed knob are designed as a column type boss, this boss is logical
The open slot connection for crossing sealed knob 2, can realize limit, compression and the locking function of upper and lower covers, can when reaching design position
The lead sealing function of implementation mechanism.As shown in figure 5, the lead sealing 3 of the present invention can pass through upper cover 1 and the through-hole on sealed knob 2,
Entire mechanism is fixed and lead sealing, prevents sealed knob 2 from offsetting, tamper, can be realized simultaneously multiple functions, and can
Meet the design requirement of appearance and modeling beauty.
In use, sealed knob 2 is mounted at the mounting hole of upper cover 1, the end cap of sealed knob 2 is made to be located at upper cover 1
Outside, ladder shaft portion are located at 1 inside of upper cover, the protrusion on sealed knob 2 are rotated to the specified restraining position of upper cover 1, this
When sealed knob 2 open slot vertically downward, sealed knob 2 is connected with the boss of lower cover 4, rotation sealed knob 2 is to specified
Position, vertically upward, to by upper and lower cover locking, upper cover 1 and sealed knob 2 is logical at this time for the open slot of sealed knob 2 at this time
Hole is just aligned, and is inserted into lead sealing 3, can effectively prevent sealed knob 2 from rotating, to reach locking connection and the lead of upper and lower covers
The effect of octant position.This mechanism may be implemented to exempt from screw installation, while reach the multiple design of locking, limit and lead sealing.
Concrete operations flow is：
1) sealed knob 2 is mounted on the mounting hole of upper cover 1, its end cap is made to be located at the outside of upper cover 1, ladder shaft portion
Positioned at 1 inside of upper cover；
2) sealed knob 2 is rotated, makes its open slot vertically downward；
3) open slot of sealed knob 2 is connect with the boss of lower cover 4；
4) sealed knob 2 is rotated, makes its open slot vertically upward, upper cover 1 and lower cover 4 is locked；
