In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the conception, specific structure and technical effects of the present invention will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all embodiments, and other embodiments obtained by those skilled in the art without inventive labor are within the scope of the present invention.
Referring to fig. 1 to 4, a preferred embodiment of the present invention is a portable stamping machine with a locking structure, which includes an inner housing 11, a stamp 23 and a driving member, wherein the stamp 23 is disposed inside the inner housing 11 and fixedly connected to the driving member, the driving member is slidably connected to the inner housing 11, and the driving member drives the stamp 23 to move up and down inside the housing along a vertical direction; a control module 31, a first locking component and a second locking component which are respectively electrically connected with the control module 31 are further arranged between the inner shell 11 and the driving part, and the first locking component is used for locking the driving part and the inner shell 11 and limiting the driving part to drive the stamp 23 to move; the second locking assembly is used to limit the distance that the driving member slides up and down along the inner housing 11.
The driving part is in sliding connection with the inner shell 11, namely the driving part can slide up and down along the inner shell 11, and in the process of sliding up and down, the seal 23 is driven to move up and down along the inner part of the inner shell 11; and the control module 31 controls the actions of the first locking component and the second locking component.
When the first locking component is not powered, the inner shell 11 and the driving component are locked, so that the driving component cannot slide along the inner shell 11, and only when the control module 31 powers the first locking component, the limitation of the locking component is removed, so that the inner shell 11 and the driving component are not locked any more, and the driving component can slide along the inner shell 11, so that the stamp 23 can be driven to slide up and down along the inner part of the inner shell 11;
when the first locking component is powered and the second locking component is not powered, the distance that the driving component can slide down along the inner shell 11 is limited to a certain distance, and specifically, the distance that the stamp 23 can slide down is limited by the second locking component; even if the driving member can drive only the stamp face of the stamp 23 to be kept in a position flush with the plane of the bottom opening of the inner case 11, it cannot drive the stamp face of the stamp 23 to move out of the plane of the bottom opening of the inner case 11.
Preferably, the first locking assembly includes a first electromagnet 41 disposed inside the inner housing 11 and a locking groove 42 disposed inside the driving member, the first armature 411 of the first electromagnet 41 is disposed in the locking groove 42, and the control module 31 controls whether the first electromagnet 41 is energized and cooperates with the locking groove 42 to limit the movement of the driving member; the second locking subassembly including locate the inside second electro-magnet 51 of interior casing 11 and vertically set up in the inside bar groove 52 of driver part, the second armature 511 of second electro-magnet 51 is arranged in bar groove 52, and control module 31 is through whether the control second electro-magnet 51 is got electric and with bar groove 52 cooperation restriction driver part along the gliding distance from top to bottom of interior casing 11.
When the first electromagnet 41 and the second electromagnet 51 are not powered, in this embodiment, the size of the slot of the locking groove 42 matches the size of the first electromagnet 41, that is, the first electromagnet 41 can just be plugged into the locking groove 42, so that the driving part and the inner housing 11 are in a locked state, the driving part cannot move up and down, the driving part cannot slide down, and the second armature 511 is placed in the strip-shaped groove 52;
when the coil of the first electromagnet 41 is energized and the second electromagnet 51 is not energized, the coil will generate magnetic force to attract the first armature 411 inwards, so that the first armature 411 will not abut against the upper end of the inner wall of the locking groove 42, the driving part can slide along the inner housing 11, the driving stamp 23 can move up and down, and at the same time, the second armature 511 will slide up and down along the strip-shaped groove 52; when the second armature 511 abuts against the top end of the bar-shaped groove 52, the driving component cannot slide downward any more, and the stamp 23 cannot move downward either, and only when a corresponding instruction is input to the control module 31, the coil of the second electromagnet 51 is energized, and the second armature 511 is sucked back, so that the second armature 511 is not clamped in the bar-shaped groove 52 any more, and the driving component can continue to drive the stamp 23 to move downward along the inner housing 11, so that the stamp 23 is completely separated from the inside of the inner housing 11, and is moved out from the bottom opening of the inner housing 11. Specifically, in the present embodiment, the length of the strip-shaped groove 52 is determined according to the distance from the original position of the stamp face of the stamp 23 to the position where the stamp face of the stamp 23 slides down to be flush with the plane of the bottom opening of the inner housing 11, that is, the length of the strip-shaped groove 52 is equal to the distance from the original position of the stamp face of the stamp 23 to the plane of the bottom opening of the inner housing 11. Therefore, the second locking assembly is mainly used for limiting the downward movement distance of the stamp 23, specifically, the stamp face of the stamp 23 can only reach the bottom opening plane of the inner housing 11 at the lowest, that is, the stamp face of the stamp 23 can dip in the inkpad or stamp, but the stamp face does not exceed the position of the bottom opening plane of the housing.
