Abstract
The utility model is a kind of bowl head gold utensil with self-closing apparatus, and self-closing apparatus includes the rotating bar being connected, locking bank；The rotating bar is installed on bowl head lower opening portion by bowl head opening inner wall both sides preformed hole, which is arranged with torsional spring, and one end is fixed on inner wall, and the other end is connected to locking bank；The locking bank height is more than bowl head open height, and the locking bank is to be rotated in axial bowl head nest, and recoil to initial position by torsional spring elastic force with rotating bar.Pass through the utility model, locking bank can be allowed to lock bowl head nest, bulb jacking is latched bank when bulb is coupled installation with bowl head, bulb enters in bowl head nest locking bank and rebounded locking bowl head nest automatically, it can be achieved that convenient installing and dismounting and bulb is not easy to fall off from bowl head nest by the elastic force of torsional spring.
Description
Technical field
The utility model is about a kind of bowl head gold utensil with self-closing apparatus.
Background technology
To be usually bulb be coupled with bowl head for insulator and the bind mode of gold utensil in overhead transmission line, bowl head gold utensil with
Bulb, which is coupled, is fixed on bulb in bowl head nest by the locking pins such as R pins or W pins.
Installation locking pin, socket-clevis eye are typically complete in high-altitude with the installation that is coupled of bulb again after bulb is coupled with bowl head
At installation personnel needs bulb being inserted in after bowl head installation locking pin again, is relatively difficult to install.In addition it dangles and insulate in " V " type
Insulator chain, which is heeling condition, in being run due to circuit in substring causes bulb to generate lasting extruding to mounting pin, for a long time by crowded
It is easy to cause the failure of bowl head locking pin after pressure, deviates from insulator chain is caused to fall string accident, shadow out of bowl head nest so as to cause bulb
Ring transmission line safety operation.
Utility model content
The technical issues of the utility model is solved is providing a kind of bowl head gold utensil with self-closing apparatus, realizes convenient installation
It dismantles and bulb is not easy to fall off from bowl head nest.
Technological means used by the utility model is as follows.
A kind of bowl head gold utensil with self-closing apparatus, wherein self-closing apparatus include the rotating bar being connected, locking bank；The rotating bar
It is installed on bowl head lower opening portion by bowl head opening inner wall both sides preformed hole, which is arranged with torsional spring, one end
It is fixed on inner wall, the other end is connected to locking bank；The locking bank height is more than bowl head open height, and the locking bank is to rotate
Bar is rotation in axial bowl head nest, and recoils to initial position by torsional spring elastic force.
Wherein, which is the baffle that top is bent into bowl head.
Technique effect caused by the utility model：A kind of bowl head gold utensil with self-closing apparatus provided by the utility model, can
To allow locking bank to lock bowl head nest, bulb jacking is latched bank when bulb is coupled installation with bowl head, bulb enters bowl head nest
Interior locking bank is rebounded locking bowl head nest, it can be achieved that convenient installing and dismounting and bulb is not easy from bowl head nest automatically by the elastic force of torsional spring
It falls off.

Fig. 2 is the structural front view of the utility model.
Fig. 3 is the structural side view of the utility model.
Fig. 4 is that the bulb of the utility model enters status diagram.
Fig. 5 is the blocking schematic diagram of the utility model.
Specific implementation mode
As Figure 1-Figure 2, the utility model is a kind of bowl head gold utensil with self-closing apparatus, and wherein self-closing apparatus 1 includes to be connected
The rotating bar 3 that connects, locking bank 2；The rotating bar 3 is installed on bowl head lower opening portion by bowl head opening inner wall both sides preformed hole,
3 both sides of rotating bar are arranged with torsional spring 4, and inner wall is fixed in 4 one end of torsional spring, and the other end is connected to locking bank 2；The locking bank 2
Height is more than bowl head open height, and the locking bank 2 is to be rotated in axial bowl head nest, and returned by 4 elastic force of torsional spring with rotating bar 3
Bullet is to initial position.
As shown in Figure 3-Figure 5, bulb jacking is latched bank when bulb is coupled installation with bowl head, which is top
The baffle that portion is bent into bowl head.Bulb enters in bowl head nest, and torsional spring 4 provides torsion for locking bank, and locking bank 2 is by torsional spring 4
Elastic force rebounds automatically locks bowl head nest, and locking 2 height of bank is more than bowl head open height, and locking bank 2 blocks bulb under locking state
Nest inlet so that bulb is not easy to fall off from bowl head.
A kind of bowl head gold utensil with self-closing apparatus provided by the utility model, can allow locking bank 2 lock bowl head nest, bulb with
Bulb jacking is latched bank 2 when bowl head is coupled installation, it is automatic by the elastic force of torsional spring 4 that bulb enters locking bank 2 in bowl head nest
Locking bowl head nest rebound, it can be achieved that convenient installing and dismounting and bulb is not easy to fall off from bowl head nest.
