Connector is that a kind of two or more components that are used for are fastenedly connected integral machine components used, is commonly used
In ship, automobile, building, in terms of plant equipment, common connector type has a bolt, stud, screw etc., and wherein bolt is pressed
Its header type is by that can be divided into turret head, round end, square spigot, countersunk head etc., and by taking hexagon socket head cap screw as an example, its head inner section is
Hexagon, when it is fastened, need to use special inner hexagon spanner to operate, and unlike monkey wrench, inner hexagon spanner it is big
Small is fixed uncontrollable, therefore also has the specification being engaged with hexagon socket head cap screw, usual head after hexagon socket head cap screw installation
Portion is exposed, and can cause to gather substantial amounts of dust in hexagon socket head cap screw head in some working environments, water stain, oil stain etc. has
When also have chip impurity and block wherein, cause and get rusty, occur situations such as blocking, so as to can not be turned；Also sometimes
The inner hexagon spanner that can not find correspondingly-sized is waited, therefore can not be opened.
For above-mentioned reason, some solutions are it is also proposed in the market, are mainly to provide dust cover or dust cap,
Then it is nested with the end of fastener, so that the cavity of connector is played a protective role, but we are, it can be seen that this
Dust cover or dust cap are primarily present two point defects, and 1, common dust cover or dust cap are easy under vibration equipment
It can drop, so that effective protection can not be played；2nd, common dust cap or dust cover can not tightly plug with molten metal the end week in connector
Side, the existing defects in placement.
The content of the invention
To solve the above problems, connecting protection device the invention discloses a kind of rack, clever structure uses simple, energy
Enough the cavity on protection connector head, installs fastening, convenient to remove, may be reused.
To reach above-mentioned purpose, technical scheme is as follows：
A kind of rack connects protection device, it is characterised in that：Including connector and guard member, the connector includes head
And connecting portion, the head is circle, and the upper plane on head is provided with polygonal grooves, and the connecting portion side is provided with least two
Symmetrical arc casting lug thereon, the guard member includes combined block and withdrawing device, and the combined block lower half is arranged in groove,
Sealant is provided with the outside of combined block lower half, the lower plane of combined block lower half is provided with symmetrical blind hole, the upper half of combined block
Portion is circle, and the withdrawing device includes press rods, pressure plare, spring, and the pressure plare is arranged on bottom portion of groove and combined block
Between the lower plane of lower half, pressure plare is provided with through hole, and the position of the through hole is corresponding with blind hole, and the press rods pass through knot
Close block to be connected with pressure plare, the spring is arranged on below pressure plare.
As a modification of the present invention, the groove is corner or hexagonal groove.
As a modification of the present invention, the sealant is rubber layer.
As a modification of the present invention, the lower half of the combined block is tapered, up big and down small.
As a modification of the present invention, the quantity of the blind hole is 2.
As a modification of the present invention, the press rods are higher by combined block 2-4mm.
As a modification of the present invention, the top of the press rods is provided with protection board.
The beneficial effects of the invention are as follows：
A kind of rack connection protection device of the present invention, clever structure, using simple, can protect connector head
Groove, install fastening, it is convenient to remove, may be reused.
