DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.

[0036] Please refer to Figures 1-11 As an embodiment of the utility model, the handcart type distribution box comprises a distribution box 1, a cabinet 2 is slidably arranged on the distribution box 1, a lock frame 3 is arranged at the bottom of the cabinet 2, and a locking mechanism is arranged on the lock frame 3.

[0037] The locking mechanism comprises an unlocking key 5 for opening and closing the cabinet 2, which rotates first and then slides in the inside of the lock frame 3 to overcome the torque;

[0038] The inside of the lock frame 3 is provided with an elastic button type switch, and the locking mechanism is used for opening and closing the elastic button type switch in the inside of the lock frame 3 to open the cabinet 2.

[0039] In this embodiment, the unlocking key 5 in the locking mechanism serves as the structure of the key in the traditional mechanical lock, and when it is needed to open the cabinet 2 on the distribution box 1, the unlocking key 5 rotates by 90 degrees first and then is pressed in the inside of the lock frame 3 to drive the internal structure to be unlocked.

[0040] As a further scheme of the utility model, the inside of the lock frame 3 is provided with a lock cavity 301, the inside of the lock cavity 301 is provided with a lock cylinder 4, and the lock cylinder 4 is connected with the unlocking key 5.

[0041] In this embodiment, as can be seen from the figure, the lock cylinder 4 is installed in the inside of the lock frame 3, and the unlocking key 5 is inserted on the lock cylinder 4.

[0042] When unlocking is needed, the unlocking key 5 needs to be rotated on the lock cylinder 4 first, so that the protrusion on the unlocking key 5 corresponds to the groove provided on the lock cylinder 4, and then the unlocking key 5 can be pressed into the inside of the lock cylinder 4, so as to complete the unlocking. Here, through rotation, only the unlocking key 5 is rotated in the inside of the lock cylinder 4, and there is no corresponding torque resistance, so as to protect the unlocking key 5 to a certain extent.

[0043] As a further scheme of the utility model, one end of the unlocking key 5 is rotationally connected with a connecting rod 6, the other end of the connecting rod 6 is rotationally connected with a pressing block 7, the cabinet 2 and the lock frame 3 are jointly provided with a sliding seat 8, and the pressing block 7 slides on the sliding seat 8.

[0044] In this embodiment, when unlocking is needed, the unlocking key 5 is rotated, and the unlocking key 5 drives the connecting rod 6 to rotate, and the other end of the connecting rod 6 is also rotationally connected with the pressing block 7. When the unlocking key 5 rotates, the connecting rod 6 constantly drives the pressing block 7 to move upwards, and since the pressing block 7 is slidably arranged on the sliding seat 8, when the pressing block 7 moves, the pressing block 7 moves upwards on the sliding seat 8.

[0045] Here, the unlocking key 5 is designed to rotate first and then press, and the groove provided on the lock cylinder 4 is designed to match the corresponding protrusion on the unlocking key 5, so that the pressing can be protected to a certain extent.

[0046] As a further scheme of the utility model, the top of the extrusion block 7 is provided with a round rod 9, the slide 8 is provided with a limiting block 10, and the limiting block 10 is in sliding connection with the round rod 9.

[0047] In the embodiment, when the extrusion block 7 moves upwards on the slide 8, the extrusion block 7 drives the round rod 9 to move in the corresponding direction, and the limiting block 10 is further installed on the slide 8 to limit the round rod 9, so that the round rod 9 and the extrusion block 7 can only move upwards in the vertical direction.

[0048] When the unlocking key 5 rotates, the extrusion block 7 moves upwards on the slide 8 in the vertical direction through the cooperation of the round rod 9 and the limiting block 10, so that the operation of the extrusion block 7 is more stable.

[0049] As a further scheme of the utility model, the round rod 9 is sleeved with a first spring 11, the bottom of the first spring 11 abuts against the top of the extrusion block 7, and the top of the first spring 11 abuts against the bottom of the limiting block 10.

[0050] In the embodiment, the first spring 11 is sleeved on the round rod 9, when the unlocking key 5 rotates, the resistance of the extrusion block 7 to the first spring 11 needs to be overcome, instead of the torque resistance, so that the unlocking key 5 is mechanically protected to a certain extent.

[0051] As a further scheme of the utility model, the end surface of the unlocking key 5 is sleeved with a second spring 12, one end of the second spring 12 abuts against the unlocking key 5, the other end of the second spring 12 abuts against a limiting ring 13, and the limiting ring 13 is arranged on the inner wall of the lock cylinder 4.

[0052] In the embodiment, when the unlocking key 5 rotates in the lock cylinder 4 and the protrusion on the unlocking key 5 corresponds to the groove arranged on the lock cylinder 4, the unlocking key 5 can be pressed straight into the lock cylinder 4, and when the unlocking key 5 is pressed in the lock cylinder 4, the unlocking key 5 extrudes in the lock cylinder 4.

[0053] As can be seen from the figure, the middle end of the unlocking key 5 extrudes the second spring 12, so that the second spring 12 is compressed in the lock cylinder 4, and the limiting ring 13 also limits the second spring 12.

[0054] As a further scheme of the utility model, the locking mechanism further comprises a guide rod 16, one end of the unlocking key 5 is provided with a first inclined block 14, the inside of the lock cavity 301 is provided with a second inclined block 15, the first inclined block 14 and the second inclined block 15 are matched in the inside of the lock cavity 301, one side of the guide rod 16 is fixedly connected with the second inclined block 15, the surface of the guide rod 16 is sleeved with a third spring 17, one end of the third spring 17 abuts against the second inclined block 15, the other end of the third spring 17 abuts against the inner wall of the lock frame 3.

[0055] In the embodiment, it needs to be noted that since the first inclined block 14 is fixedly connected with the unlocking key 5, when the unlocking key 5 is first reversed by 90 degrees in the inside of the lock cylinder 4, the corresponding first inclined block 14 will also rotate by the same angle, as can be seen from the figure, when the first inclined block 14 also rotates by the corresponding angle, correspondingly, the wedge surfaces of the first inclined block 14 and the second inclined block 15 match, so that when the first inclined block 14 is pressed in the inside of the lock cylinder 4, the first inclined block 14 will extrude the second inclined block 15, the first inclined block 14 moves in the deeper direction of the inside, and correspondingly the second inclined block 15 will move to both sides, so that the second inclined block 15 will also move the guide rod 16 to one side, since the third spring 17 is arranged between the inner wall of the lock frame 3 and the second inclined block 15, when the second inclined block 15 moves, the third spring 17 will also be extruded, so that the third spring 17 also stores a certain elastic potential energy;

[0056] It needs to be noted that when the unlocking key 5 is pressed in the inside of the lock cylinder 4, the connecting rod 6 will slide on the surface of the round shaft of the extrusion block 7.

[0057] As a further scheme of the utility model, the lock frame 3 is further provided with a switch groove 302, one end of the guide rod 16 is slidably arranged in the inside of the switch groove 302, and the guide rod 16 is used for opening and closing the elastic button type switch arranged in the inside of the switch groove 302.

[0058] In the embodiment, when the guide rod 16 is driven by the second inclined block 15, the inside of the switch groove 302 is designed with an elastic button type switch, when the guide rod 16 touches the switch, the cabinet 2 will be unlocked and opened, so that it can be pulled out from the inside of the distribution box 1, conversely, when it is needed to close the cabinet 2, the guide rod 16 only needs to be pressed again to open the switch, that is, the unlocking key 5 is first rotated and then pressed in the inside of the lock cylinder 4.

[0059] It should be noted that when the guide rod 16 opens the switch, at this time the unlocking key 5 needs to be slowly pulled out from the inside of the lock cylinder 4, because at this time the third spring 17 and the second spring 12 are jointly reset by the force, the force required to be used is small, when the protrusion on the unlocking key 5 leaves the groove opened on the lock cylinder 4, under the reset force of the first spring 11, the unlocking key 5 will rotate to the initial position again, when it is needed to be unlocked again, only the above operation needs to be repeated.

[0060] The above examples are exemplary rather than limiting, and therefore, the technical solutions of the present application can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application, and all technical solutions of the present application are included in the present application.
