Description
Technical field
The utility model is related to a kind of bolt arrangement, belongs to hydroelectric facility accessory technical field, and in particular to sealing
A kind of good knockdown waterproof bolt device of energy.
Background technology
In the connection and fastening of mixed mud built-in fitting part, mostly using standard fasteners, these standard fasteners exist
When playing connection and fastening effect, there are some shortcomings, it is impossible to reach waterproof effect well.Such as fix pneumatic gate valve fixture
On bolt, be immersed in for a long time in water, bolt gets rusty easily and causes loosening, shortens service life.Develop a kind of new
Type is solid and reliable, convenient to install and maintain, and the pre-buried inclination fixing bolt device of good seal performance is imperative.
Utility model content
For deficiencies of the prior art, the purpose of this utility model is to provide a kind of solid and reliable, and cost is low
Honest and clean, the pre-buried inclination fixing bolt being convenient to process and mount.
To achieve the above object, the technical solution adopted in the utility model is as follows：
Pre-buried inclination fixing bolt, including the discoidal base being embedded in mixed mud and the circle being hinged on base
Conduit, and the screwed screw rod in two ends, the screwed screw rod one end in described two ends and the conduit being embedded in mixed mud
The threaded engagement connection that inwall is set, the other end exposes on mixed mud surface, the described other end and bar that are exposed at mixed mud surface
The nut connection of shape coordinates, under described nut, provided with water proof ring up and down；During fixed component, the screw set on fixture is worn
Cross provided with up and down water proof ring screw rod, by fixture be placed in above and below collision mat centre, tighten bar shaped nut by segment hub seal in bar
In shape nut.
The utility model is particularly suitable for mixed mud fixture special bolt accessory under water.Base uses disc-shaped structure, by
Power area is wide, solid and reliable；Screw rod one end is connected with the threaded engagement set in the conduit of bottom, is easily installed and is changed, mixed mud table
Face is provided with closed bar shaped nut, good with waterproof seal.

Embodiment
Reference picture 1, Fig. 2, pre-buried inclination fixing bolt, including the discoidal base (1) and hinge being embedded in mixed mud
It is connected on the circular pipe (2) on base (1), and the screwed screw rod in two ends (3), the screwed screw rod in described two ends
(3) screw thread (7) that one end is set with conduit (2) inwall being embedded in mixed mud is connected, and the other end exposes on mixed mud surface,
The other end for being exposed at mixed mud surface and the connection of the nut (5) of bar shaped coordinate, under described nut (5), provided with anti-up and down
Hydrosphere (4), during fixed component, the screw set on fixture is passed through provided with collision mat (4) screw rod (3) up and down, fixture is put
In the centre of water proof ring up and down, bar shaped nut (5) is tightened by segment hub seal in bar shaped nut；When changing screw rod (3), from inverse time
Pin direction rotates the nut (5) of bar shaped, just can pull out screw rod (3) and change.
Finally, it should be noted that above example is only to illustrate the technical solution of the utility model rather than to this hair
The limitation of bright protection domain, although being explained in detail with reference to preferred embodiment to the utility model, the ordinary skill of this area
Personnel should be appreciated that can modify or equivalent substitution to the technical solution of the utility model, new without departing from this practicality
The spirit and scope of type technical scheme.
