Description
Technical Field
The utility model relates to a connecting piece field especially involves the bolt field, specifically indicates a split type spout location lock bolt.
Background
The shield segment adopts pre-buried spout to be used for the installation of fire hose, evacuation platform in the tunnel to and cable support etc. the spout location is fixed in the trompil of mould, fixes a position the fitting pin installation with the spout and fixes a position the fitting pin bottom and be phi 10 screw rod, upper portion is the phi 6 lead screw. The bolt is integral spout fixing bolt among the prior art, easily causes the upper portion lead screw to damage during form removal, and the upper portion lead screw damage leads to whole bolt all to need to be changed, and integral spout fixing bolt changes and needs artifical the interior bolt of dismantling that bores into the mould, wastes time and energy, and has great potential safety hazard.
SUMMERY OF THE UTILITY MODEL
The utility model discloses to prior art's not enough, provide a split type spout location lock bolt, make things convenient for the change of lead screw.
The utility model discloses a through following technical scheme realization, a split type spout location lock bolt, including the bolt cap to and with bolt cap threaded connection's screw rod, the screw rod include with bolt cap threaded connection's lead screw to and location fitting pin, the screw hole that extends along location fitting pin length direction is seted up to the bolt head of location fitting pin, screw hole and lead screw thread adaptation.
The utility model discloses when using, run through behind mould arc and the reinforcing arc with the location fitting pin and be connected with not hard up nut, then aim at the location fitting pin with the trompil on the spout, through the location fitting pin with the chute position fixed, twist the lead screw into the location fitting pin again, at last with bolt cap and lead screw threaded connection, compress tightly the spout through the bolt cap, after the smooth silk of lead screw damages, only need with the lead screw from the location fitting pin unscrew change can, the change of lead screw has been made things convenient for, the whole change of bolt has been avoided.
Preferably, the top of the bolt cap is provided with a handle. According to the optimization scheme, the handle on the bolt cap is rotated to drive the bolt cap to rotate, the bolt cap drives the screw rod to be screwed into the threaded hole I, and the screw rod is screwed conveniently, labor-saving and fast.
Preferably, a bolt cap gasket is sleeved on the bolt cap. This preferred scheme plays the effect of relaxing of bolt cap and bolt on the one hand through setting up of bolt cap gasket, and effort between on the other hand buffering bolt cap and the spout plays the effect of protection bolt cap.
Preferably, the bolt head of the positioning locking pin is in a long hole shape matched with the chute groove hole. This preferred scheme is through the setting of bolt head trompil form, with the structure looks adaptation of spout trompil form, when the spout installation, gives the spout with the guide effect.
Preferably, the top of the screw rod is provided with a countersunk hole extending vertically. This preferred scheme is convenient for twist out the lead screw from the location fitting pin through the spanner through the setting of counter sink.
Preferably, the length of the screw hole is less than the length from the head of the bolt to the thread of the positioning locking pin. According to the optimized scheme, the phenomenon that the strength of the threaded section of the locking pin is influenced due to the overlong threaded hole is avoided, and the strength of the locking pin is further influenced.
The utility model has the advantages that: the screw rod is respectively in threaded connection with the bolt cap and the positioning locking pin, so that the screw rod can be conveniently replaced when damaged; the arrangement of the bolt cap handle facilitates the threaded connection of the threaded cap and the screw rod; the screw rod is conveniently screwed out of the screw hole through the arrangement of the inner hexagonal countersunk head; through the arrangement of the long hole shape of the positioning locking pin head, the guide effect is achieved when the sliding groove is installed.
