Description
Technical field
The utility model is related to a kind of sealing device, more particularly to a kind of bolt sealing device for being used to fix arc.
Background technology
The applicant's earlier application one entitled " the box pipeline with circumferential obtuse angle connection ", Application No.
Use to bolt more 201610649976.0 patent of invention, its corrugated sheet steel and other connecting elements and be connected stress, it is whole to ensure
The intensity of body structural member, but when integral structure component needs sealing effectiveness, in view of corrugated sheet steel has radian, enter with bolt
During row bolt, bolt is difficult to fit well with corrugated sheet steel contact position, so using between bolt and corrugated sheet steel
Setting up sealing gasket recycles bolt to tighten up and be difficult to good sealing effectiveness.
It would therefore be highly desirable to solve above-mentioned technical barrier.
Utility model content
Utility model purpose：It is used to strengthen bolt and arc when the purpose of this utility model is to provide a kind of fixed arc
The sealing device of sealing between plate.
Technical scheme：The bolt sealing device of the present utility model for being used to fix arc, the arc passes through bolt
It is fixed on connector, wherein, the screw rod of the bolt sequentially passes through connector and arc, and uses nut check, the screw rod
Bottom is cased with seal cap, and the inner surface of the cap mouthful and arc of the seal cap fits, and the cap mouthful laminating end of seal cap and arc
The first sealing ring is provided between shape plate.
Further, the arc has plane and the arcwall face being connected with it, and cap mouthful and the arc of seal cap are put down
The inner surface in face fits.
Wherein, the inwall of the seal cap is the female thread structure matched with external screw thread on screw rod, and being tightened up by spiral can
With good tie down screw, sealing gasket and corrugated sheet, effective sealing is realized.
Meanwhile, the cap mouthful laminating end for the seal cap fitted with the arcwall face or plane of the arc is provided with limitation first
Neck from sealing ring to the unordered diffusion of surrounding so that seal cap lock when, the first seal cap can be fixed and clamped in neck, have
Laying beneficial to the first sealing ring is firm and sealing ring and arc are fitted, so as to improve sealing effectiveness.Wherein, when described
When arc has plane and the arcwall face being connected with it, the cap of seal cap mouthful laminating end also either flush end mouth structure, at end
Mouthful arc between sealed using flat sealing ring.
Further, the seal cap is prolonged from the first cap for tie down screw, from the first cap bottom to both sides
Being used for of stretching and formed after being folded upward at compresses the second cap of arc, and extends upwardly to the from the second cap end
The cap seat for being used to compress the first sealing ring at one sealing ring is mutually spliced.Cap extrudes cap seat by spiral locking, so that
The first sealing ring is compressed, strengthens overall locking effect.
When the arc there is plane and be connected with it arcwall face when, the end of above-mentioned the second cap can also be to
On extend directly to compress the first sealing ring, cap by spiral locking the second cap of extruding so as to compress the first sealing ring,
Strengthen overall locking effect；The seal cap can also be formed in one.
Because when the arc there is plane and be connected with it arcwall face when, due to seal cap by screw-pressing in arc
In shape plate plane, its cap mouthful and the inner surface of arc plane fit, and when seal cap is integrally formed, can directly rotate close
Sealing cap, locks it；When seal cap is by the first cap, the second cap, when being mutually spliced with cap seat, can first it dispose
Cap seat, then realize locking by rotating the first cap.But if the arc does not have plane, seal cap exists screw-pressing
While on arc, the inner surface of its cap mouthful and arc fits, it is contemplated that the structure of similar trough, institute inside arc
With can not the direct whole seal cap of rotational lock, so seal cap can only be by the first cap, the second cap, with cap seat mutually
It is spliced, in use, first placement cap seat, then coordinate the second cap clamping cap seat by rotating the first cap.
Further, when the seal cap is mutually spliced, the stitching portion of cap seat and the second cap sets up the
Two sealing rings, to solve the leakage problems between cap seat and cap.
Further, first sealing ring and the second sealing ring are ethylene propylene diene rubber or hydro-expansive rubber.
Operation principle：There is radian deviation during bolt connection arc, between screw rod and arc, with nut check
Meanwhile, then the seal cap of a locking is set up, and sealing ring is set between cap mouthful and arc, during lock sealing cap, seal cap
Sealing ring is pressed in arc, sealing function is played；The arc produces movement when in use, cause cap mouthful, sealing ring and
Be subjected to displacement between arc, can by setting neck in cap mouthful, for seal cap when compressing clamping sealing ring, prevent sealing
Circle produces position skew when device is moved, so as to influence device sealing effectiveness；For convenience of production and processing, seal cap is made
By the Split type structure of cap seat connection cap, tightened up by the screw thread in cap and cause cap to be pressed in arc, and by cap
Seat and cap junction set sealing ring to improve sealing effectiveness.
Beneficial effect：Compared with prior art, advantage of the present utility model is：(1) bolt sealing device connects to arc
At seam and thread gaps all carry out encapsulation process, the sealing of the device is effectively increased；(2) sealing of the bolt sealing device
Cap is by cap mouthful neck come fixed seal ring so that the arc does not interfere with whole dress even if being moved when in use yet
The sealing put；(3) bolt sealing device is demountable structure, is made and easy for installation, with good exploitativeness.
