One end of the handle is hinged to one end of the inner shaft in the shaft hole at one end of the base and is provided with a torsion spring. The other end of the inner shaft in the base extends out and is connected to an actuator through a shaft screw. A positioning piece is provided at the bottom orifice of the shaft hole of the actuator at the base. The other end of the handle in the handle groove of the base is provided with a lock core assembly. The lock head at the bottom of the lock core assembly extends out of the handle and is fixed in a lock groove in the base. The key point of its structural design is that a lock shell is provided at the lock groove in the base. A lock hook elastic piece is provided on one side inside the lock shell. One end of the lock hook elastic piece is aligned with the lock head of the lock core assembly. A hook groove is provided at the other end of the lock hook elastic piece. A convex column at one end of a pin is limited in the hook groove on one side of the lock hook elastic piece for buckling. A first spring is provided at the bottom of this end of the pin. The other end of the pin extends out of the lock shell and abuts against the bottom of one end of the lock core assembly of the handle in the handle groove. When the lock head of the lock core assembly rotates to unlock with the lock groove in the base, the lock head of the lock core assembly pushes the lock hook elastic piece to move towards the hook groove side. The hook groove of the lock hook elastic piece is disengaged from the hook groove of the pin. While the handle pops out of the handle groove of the base through the torsion spring, the handle pops out of the handle groove of the base left and right through the pin and the first spring, and the lock hook elastic piece is reset through elastic action. When the handle is pressed and received into the handle groove of the base, the handle pushes the pin to reset. The convex column of the pin is buckled and engaged with the hook groove of the lock hook elastic piece. The pin is received into the lock shell, and the lock head of the lock core assembly is buckled and locked with the lock groove in the base. The above lock hook elastic piece undergoes displacement changes through self-locking elastic interference deformation or the action of the following second spring. The convex column of the pin is an integrally formed protrusion or the following inserted pin.

[0005] One end of the groove of the lock hook elastic piece abuts against the inner wall of the lock shell through a second spring, and the lock hook elastic piece is reset through the elastic action of the second spring. The above structure further improves the reset effect of the lock hook elastic piece.

The shape of the positioning grooves corresponds to the triangular heads protruding from both sides of the bottom of one end of the rotating shaft of the upper handle. Above one end of the positioning groove of the base, an arc-shaped groove is provided on the inner wall of the end of the handle groove of the base. When the handle pops out, the end of this end of the handle rotates corresponding to the arc-shaped groove of the base. The above structural design reduces the gap between the handle and the handle groove in the base, improves the dust-proof and sealing effect of the handle, and it can also be realized by the hemispherical inner wall of the base inner wall at the handle of one end of the rotating shaft.

[0009] At the top notch of the handle groove of the base, a sealing gasket higher than the notch of the handle groove is provided. The top plane of the handle is aligned with the ring plane of the sealing gasket. On the outer diameter of the handle groove of the base, at least two pairs of symmetrically and equidistantly arranged protruding base mounting ears are provided. The sealing mounting ears of the sealing gasket are embedded in the grooves at the base mounting ears of the base. The above structure further improves the sealing performance and dust-proof effect of the base and the handle.

[0010] At the top keyhole of the lock core assembly of the handle, a dust-proof cover is provided. The dust-proof cover screw of the dust-proof cover passes through the handle and abuts against the end of the pin column below. The above is an embodiment where the dust-proof cover abuts against the pin column, and it can also be realized by the bottom of the handle abutting against the pin column.

[0011] The actuator is a steel bolt assembly, a connecting rod assembly or a steel bolt connecting rod assembly. The above is the specific structure of the actuator, which is set according to actual needs.

[0012] At the protruding end of the pin column, a magnet is provided. When the protruding column of the pin column is buckled and engaged with the hook groove of the lock hook elastic piece, the magnet corresponds to the Hall sensor in the lock shell, or the magnet corresponds to the Hall sensor on the outer diameter of the base through a through hole on one side of the base. Thus, it is convenient to confirm whether the pin column is reset by the pressing of the handle through the interaction between the Hall sensor and the magnet of the pin column, so as to confirm whether the handle is retracted into the base.

A positioning piece 15 is arranged at the bottom orifice of the shaft hole of the base at the actuator. The actuator is a steel bolt assembly 8. At the other end of the handle in the handle groove of the base, there is a lock core assembly 6. The lock head 601 at the bottom of the lock core assembly extends out of the handle and is fixed in the lock groove in the base. A lock shell is arranged at the lock groove in the base. On one side inside the lock shell, there is a lock hook spring piece 7. One end of the lock hook spring piece is aligned with the lock head of the lock core assembly. The other end of the lock hook spring piece is provided with a hook groove 701. This end of the lock hook spring piece abuts against the inner wall of the lock shell through a second spring 13. A horizontally penetrating pin 14 is arranged in the hook groove of the lock hook spring piece. On one side of the hook groove of the lock hook spring piece, there is a hook for locking the pin. The pin is fixedly arranged at one end of a pin column 10 inserted into the lock shell. At the bottom of this end of the pin column, there is a first spring 11. The other end of the pin column extends out of the lock shell and abuts against the bottom of one end of the lock core assembly of the handle in the handle groove. When the lock head of the lock core assembly rotates to unlock the lock groove in the base, the lock head of the lock core assembly pushes the lock hook spring piece to move towards the side of the hook groove. The hook groove of the lock hook spring piece disengages from the hook groove of the pin column. While the handle pops out of the handle groove of the base through the torsion spring, the handle pops out of the handle groove of the base left and right through the pin column and the first spring, and the lock hook spring piece resets through the elastic action of the second spring. When the handle is pressed and retracted into the handle groove of the base, the handle pushes the pin column to reset. The pin of the pin column engages with the hook in the hook groove of the lock hook spring piece. The pin column is retracted into the lock shell, and the lock head of the lock core assembly engages and locks with the lock groove in the base.

[0023] The horizontally arranged pin of the above-mentioned pin column horizontally penetrates and is arranged in the hook groove of the lock hook spring piece. At the same time, one end of the pin extends out of the sliding groove on one side of the lock shell. The lock shell includes a lock shell base 5 and a lock shell cover 12. The lock hook spring piece, the pin column, the first spring, the second spring 13, and the pin are arranged inside the lock shell formed by the lock shell base and the lock shell cover. One end of the lock hook spring piece extends out of the lock shell and is aligned with the lock head of the lock core assembly. The top of the pin column extends out of the lock shell. On both sides of the shaft hole of the base, there are symmetrically arranged positioning grooves 101. The shape of the positioning groove corresponds to the triangular heads 201 protruding from both sides of the bottom of one end of the shaft of the upper handle. Above one end of the positioning groove of the base, on the inner wall of the end of the handle groove of the base, there is an arc groove 102. When the handle pops out, the end of this end of the handle rotates corresponding to the arc groove in the base.

[0024] At the top orifice of the handle groove of the above-mentioned base, there is a sealing gasket 4 that is higher than the orifice of the handle groove. The top plane of the handle is aligned with the orifice plane of the sealing gasket. On the outer diameter of the handle groove of the base, there are six pairwise symmetric and equidistantly arranged protruding base mounting ears. The sealing mounting ears of the sealing gasket are embedded in the grooves at the base mounting ears of the base. At the top keyhole of the lock core assembly of the handle, there is a dust cover 3. The dust cover screw 9 of the dust cover passes through the handle and abuts against the end of the lower pin column.

[0025] During use, turn to open the dust cover, insert the key into the keyhole of the lock core assembly, turn the key, and the key drives the lock head at the bottom of the lock core assembly to rotate. The lock head pushes one end of the lock hook spring piece, and the handle pops out of the base under the simultaneous action of the torsion spring and the second spring at the bottom of the pin. Rotate the handle, and the bolt assembly at the bottom of the base can be driven by the rotating shaft to rotate to achieve unlocking or locking.

[0026] According to the above structural features, the above-mentioned actuator can also be a connecting rod assembly or a bolt connecting rod assembly. A magnet is provided on one end of the convex column or pin of the above-mentioned pin. When the convex column of the pin is buckled with the hook groove of the lock hook spring piece, the magnet corresponds to the Hall sensor in the lock case, or the magnet corresponds to the Hall sensor on the outer diameter of the base through the through hole on one side of the base, so as to realize the electronic lock method to judge whether the handle pops out and then resets.

[0027] To sum up, on the basis of the torsion spring of the existing product, an auxiliary handle is added to the tail of the handle of this handle flat lock. This handle flat lock is especially applied to the charging pile of the existing new energy vehicle, meeting the requirement that the overall lock is hidden in the cabinet, but the handle needs to pop up automatically. There is no solution in the current market for the two problems of hiding only the handle of such a lock and ensuring the stable pop-up of the handle. This solution can perfectly solve the pain points of customers.
