Description
Technical field
The utility model belongs to distribution box lock technology field, is related to a kind of gravity self-locking device for distribution box.
Background technique
In the prior art, a degree of seismic wave can be generated in non-metal mine underground mining ore bursting work,
Seismic wave can cause the fluctuation of the earth's crust in a certain range.During underground mining operations, numerous electric power that underground will use are set
Standby especially distribution box, since the material of distribution box lock core is aluminum, lock core in the environment of receiving earthquake wave action for a long time,
Fracture damage can occur, cause distribution box door is in the open state can not close, to influence built-in electronic component by shadow
It rings, also seriously affects the personal safety of operator, there are security risks.
Summary of the invention
The purpose of this utility model is to solve influence fracture of the prior art there are distribution box lock core vulnerable to seismic wave to make
The technical issues of can not closing at distribution box door, provides a kind of gravity self-locking device for distribution box, to overcome the prior art
Deficiency.
To achieve the goals above, a kind of gravity self-locking device for distribution box of the utility model, it includes having case
The distribution box of door；The chamber door is equipped with hole of button；
The hole of button is equipped with the fastening fiber tube that is mutually inserted with it, and fastens fiber tube and pass through the limiting wire that connects with it
Ring is fixed on hole of button；
The inner radius of the fastening fiber tube is equipped with jack, and one shaft of activity grafting in jack；The shaft is located at chamber door
One end of inside is equipped with lock bolt, and is fixedly connected in the middle part of shaft and lock bolt；One end that the shaft is located on the outside of chamber door is equipped with
The self-locking nut connect with it；The outside of the self-locking nut is equipped with the locking nut connect with the mutual silk of shaft, and locking nut
Side be equipped with pin hole I；The pin hole I is mutually inserted fixation by the pin hole II of fixed pin and shaft one end；
The locking nut is fixedly connected with one end of handle, and the other end of handle is equipped with weighted spherical ball；The handle and lock
It is in 90 ° between door bolt staggeredly to correspond to.
It loosens in order to prevent, the limiting wire ring mutually fastens limit by stop block and fastening fiber tube.
The structure design of the utility model is reasonable, novel, and lock bolt is staggeredly corresponding in 90 ° with handle by shaft, in weighted spherical ball
Under the action of centrifugal force, handle remains the state of naturally drooping, to guarantee that lock bolt is in horizontal locking state, not by
The influence of seismic wave realizes the self-locking of distribution box door.
Detailed description of the invention
Fig. 1 is the structural representation broken away view of the utility model.
Fig. 2 is the use state of the utility model with reference to figure.
1, lock bolt 2 in figure, pin hole II 4, limiting wire ring 5, stop block 6, fastening fiber tube 7, is inserted at shaft 3
Hole 8, self-locking nut 9, fixed pin 10, locking nut 11, pin hole I 12, handle 13, weighted spherical ball.
Specific embodiment
Referring to Figures 1 and 2, the utility model it include the distribution box with chamber door；The chamber door is equipped with hole of button；
The hole of button is equipped with the fastening fiber tube 6 that is mutually inserted with it, and fastens fiber tube 6 and pass through the limit that connects with it
Silk ring 4 is fixed on hole of button；
The inner radius of the fastening fiber tube 6 is equipped with jack 7, and one shaft 2 of activity grafting in jack 7；The shaft 2 is located at
One end on the inside of chamber door is equipped with lock bolt 1, and shaft 2 is fixedly connected with the middle part of lock bolt 1；The shaft 2 is located on the outside of chamber door
One end is equipped with the self-locking nut 8 connect with it；The outside of the self-locking nut 8 is equipped with the locking nut connect with the mutual silk of shaft 2
10, and the side of locking nut 10 is equipped with pin hole I 11；The pin hole I 11 passes through II 3 phase of pin hole of fixed pin 9 and 2 one end of shaft
Mutually it is plugged and fixed；
The locking nut 10 is fixedly connected with one end of handle 12, and the other end of handle 12 is equipped with weighted spherical ball 13；It is described
It is in 90 ° staggeredly corresponding between handle 12 and lock bolt 1.
It loosens in order to prevent, the limiting wire ring 4 is limited by stop block 5 and the mutually fastening of fastening fiber tube 6.
Working principle: limiting wire ring 4 and fastening fiber tube 6 are fixed on chamber door, can prevent from loosening by stop block 5；Shaft 2
It is passed through from jack 7, one end is fixedly connected with the center of lock bolt 1, to ensure that lock bolt left and right ends balance；Other end self-locking nut 8
It is fixed, and certain interval is reserved with fastening fiber tube 6 convenient for rotation.Handle 12 is corresponding in 90 ° with lock bolt 1, in its natural state, ground
For heart gravitation to remaining straight down under the action of weighted spherical ball 13, lock bolt 1 keeps horizontal realization self-locking.If you need to open distribution box
When, handle 12 need to be only rotated by 90 ° and be pulled outwardly；When closing distribution box door onto, door need to only be shifted to position, decontroling handle is
Can, seismic wave can be effectively prevent to cause the damage of distribution box door lock in underworkings.
