Abstract
The utility mode relates to the field of elevators, particular to a safety triangular lock. The safety triangular lock comprises a lock case, a plug and a lock rod, the plug penetrates the lock case to be connected with the lock rod, a torsion spring is arranged between the lock case and the lock rod, and the plug drives the lock rod to rotate. The safe triangular lock has the advantages of being ingenious in design, novel in structure, convenient to operate due to the fact that a user only needs to rotate the plug, and low in cost.
Description
Technical field
The utility model relates to the elevator field, especially a kind of triangle of safety lock.
Background technology
Along with the development of modern architecture, elevator is absolutely necessary, and in the time of elevator faults, electric switch is very insurance not, also needs mechanical switch usually, can open elevator artificially, but safety lock design at present is complicated and operation inconvenience.
Summary of the invention
In order to solve the complicated and unhandy technical problem of above-mentioned safety lock design, the utility model provides a kind of triangle of safety lock.
The technical solution of the utility model is as follows:
A kind of triangle of safety lock comprises lock housing, lock core and locking bar, and described lock core passes lock housing and is connected with locking bar, is provided with torsion spring between described lock housing and the locking bar, and described lock core drives locking bar and rotates.
As preferably, described lock housing bottom notch is jagged, described lock core top is provided with tapered end, and the lock core bottom is provided with inserting column, and described locking bar top is provided with the mount pad that card is established inserting column and torsion spring, described locking bar top is provided with locating piece, described lock core cover upper gasket sees through lock housing and is stuck on the mount pad, and described torsion spring one end is fixed on the locking bar, and the torsion spring other end is stuck in the breach together with locating piece, lock core and locking bar are by bolt, and described locking bar is provided with the lock body on band inclined plane.
As preferably, described lock housing outer wall is provided with screw thread, is used for installing nut.
Use the technical solution of the utility model, design ingenious, novel structure, easy to operate, rotational lock core gets final product, cost is low.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment
A kind of triangle of safety lock as shown in Figure 1 comprises lock housing 3, lock core 1 and locking bar 6, and described lock core 1 passes lock housing 3 and is connected with locking bar 6, is provided with torsion spring 4 between described lock housing 3 and the locking bar 6, and described lock core 1 drives locking bar 6 and rotates.
Described lock housing 3 bottom notch are jagged, the breach position is considered as lock housing 3 bottoms, described lock core 1 top is provided with tapered end 9, tapered end 9 positions are considered as lock core 1 top, tapered end 9 is triangle columns, lock core 1 bottom is provided with inserting column 8, inserting column 8 is cubics, described locking bar 6 tops are provided with the mount pad 10 that card is established inserting column 8 and torsion spring 4, card inserting column 8 in the mount pad 10 is installed torsion spring 4 between mount pad 10 and the locking bar 6, described locking bar 6 tops are provided with locating piece 11, described lock core 1 cover upper gasket 2 sees through lock housing 3 and is stuck on the mount pad 10, described torsion spring 4 one ends are fixed on the locking bar 6, and torsion spring 4 other ends are stuck in the breach together with locating piece 11, and at this moment torsion spring has produced torsion, rotate relieving and can automatically reply the position, lock core 1 and locking bar 6 are fixing by bolt 7, and lock core 1 inwall is provided with screw thread, are convenient to install, described locking bar 6 is provided with the lock body 12 on band inclined plane, and described lock housing 3 outer walls are provided with screw thread.
During use, with nut 5 lock housing 3 is fixedly mounted on the elevator door, locking bar 6 contacts with corresponding components, when elevator needs artificial the unlatching, make lock body 12 extruder members get to purpose by rotational lock head 9, because extrusion friction is many, lock body 2 outer rims are the curved surfaces that tilt, the dynamics of reducing friction, life-saving.
