Description
Technical Field
The invention belongs to the field of machine manufacturing, and particularly relates to a non-return unlocking mechanism, a launching system and a toy gun.
Background
The principle of the mechanical launching system for launching operation is that motor power is conducted through n (2-6) stage gears under the condition of electrification, the end tooth-missing gear pulls the piston to pre-compress the main spring, and then the piston can move forwards by releasing the main spring, so that the launching action is realized. However, in actual operation, the motor may be powered off to reverse the gear with missing teeth, which results in failure of compressing the main spring, therefore, in order to prevent the spring from being compressed due to the power off of the motor in the process of compressing the main spring, the conventional launching system is usually provided with a non-return device for ensuring the unidirectional rotation of the gear and preventing the reverse rotation of the gear.
However, the following disadvantages exist after the non-return device is added to the launching system: when the launching system is in a non-working state, the motor is in a power-off state, but the non-return device locks the gear because the power-off time of the motor cannot be accurately controlled, and finally, the main spring is in a compression state with different degrees for a long time in the non-working state, and in a static state that the main spring is compressed with high strength, the following problems can be caused: (1) when the system is restarted, the phenomenon that the system needs to be restarted with great force due to the large elasticity and the large compression degree of the main spring can occur, and at the moment, if the motor can not output enough power, the system can be locked or internal parts of the system can be damaged due to overlarge pressure; (2) the problem that the main spring has higher probability of being in a continuous compression state when the system is stored due to the fact that the motor cannot be accurately controlled to operate can occur, and therefore the performance of the spring is seriously reduced and the service life of the spring is shortened when the system is in a non-working state.

The driving gear 7 may be driven manually or electrically, and when an electric drive is used, a driving mechanism is further included, which drives the driving gear 7 to rotate. The drive mechanism includes, but is not limited to, a motor or an electric machine. The intermediate transmission gear 8 may be one or more gears, and when there are a plurality of intermediate transmission gears 8, the plurality of intermediate transmission gears 8 are engaged in sequence. The tail end gear comprises a first gear and a second gear which is fixedly integrated with the first gear, the first gear and the second gear rotate synchronously, the first gear is a full-tooth gear 10 meshed with the middle transmission gear 8, and the second gear is a tooth-lacking gear 9 meshed with the rack 21. The first gear is fixedly arranged above or below the second gear.
When the driving gear 7 is driven to rotate, the intermediate transmission gear 8 and the ratchet wheel 1 are sequentially driven to rotate, the intermediate transmission gear 8 rotates to drive the first gear to rotate, the first gear rotates to drive the second gear to rotate, the second gear is the gear 9 with the missing teeth, the gear 9 with the missing teeth is preferably a sector gear, the gear 9 with the missing teeth comprises a gear part and a non-tooth part, when the gear 9 with the missing teeth rotates to the position where the gear part is meshed with the rack 21, the piston rod 2 is pulled through the rack 21 to compress the elastic part 3, when the gear 9 with the missing teeth rotates to the position where the non-tooth part corresponds to the rack 21, no action is performed between the gear 9 with the rack 21, the elastic part 3 resets, and the piston rod 2 moves in the direction opposite to the previous direction under the action of the elastic thrust.
Further, as shown in fig. 1 and 2, the end of the piston rod 2 away from the elastic member 3 is a shooting end 22, and under the reciprocating pushing action of the piston, the bullet is shot out through the shooting end 22. The toy gun of the present embodiment is not limited to the material, shape, and performance of the bullet to which it is applied.
As shown in fig. 1 and 2, and fig. 5 and 6, the backstop unlocking mechanism includes a ratchet assembly, an unlocking assembly and a control assembly. The ratchet assembly comprises a ratchet 1 and a backstop pawl 4 for preventing the ratchet 1 from reversing; the unlocking assembly comprises a movable plate part 5 arranged close to the non-return pawl 4 and a convex rod protruding out of the plate surface of the plate part 5, preferably, the plate part 5 is arranged above the non-return pawl 4 in a pivoting mode, and when the plate part 5 rotates towards the direction close to the non-return pawl 4, the convex rod can push the non-return pawl 4 to rotate towards the direction away from the ratchet 1; the control assembly comprises a controller piece which is movably or rotatably arranged above the plate part 5, the lower end part of the controller piece and the upper end part of the plate part 5 form a non-return interaction structure, and when the controller piece moves a certain preset distance or rotates a certain preset angle, the plate part 5 is pressed to rotate towards the direction close to the non-return pawl 4; when the ratchet pawl 4 is disengaged from the ratchet 1, the ratchet 1 can be driven to rotate reversely. The cross-sectional shape of the nose bar is not limited in this embodiment. The plate portion 5 is located above the ratchet pawl 4, and it is understood that the plate portion 5 is located above the plane of the ratchet pawl 4, and it is also understood that the plate portion 5 is located above the space of the ratchet pawl 4. Of course, it is within the spirit and scope of the present invention that the ratchet pawl 4 can be separated from the ratchet wheel 1 only when the engaging position of the ratchet pawl 4 with respect to the ratchet wheel 1 is below the plane of the plate portion 5 pivotally disposed on the ratchet pawl 4.
When the toy gun is not in use, the driving mechanism is powered off and stops supplying power to the driving gear 7, and the driving gear 7, the intermediate transmission gear 8 and the end gear are all stopped. Because the power-off time of the driving mechanism cannot be accurately judged, the gear part of the gear 9 with missing teeth is meshed with the rack 21 possibly after the power-off of the driving mechanism, the elastic part 3 is still in a compressed state, but the ratchet wheel 1 stops rotating, and the ratchet wheel 1 is locked by the non-return pawl 4 to ensure that the ratchet wheel 1 cannot rotate reversely, so that the whole gear assembly is in a locked state, and the elastic part 3 cannot rebound. When the elastic element 3 is in a high-strength compression state for a long time, the driving mechanism needs to output larger power to restart the gear set to operate when the system is restarted, and if the power of the driving mechanism is insufficient, the system is locked or internal parts of the system are damaged due to overlarge pressure. In addition, the long-term compression of the elastic member 3 during non-use of the toy gun can also seriously affect the elastic performance and the service life. Therefore, the present embodiment can timely release the matching state of the ratchet pawl 4 and the ratchet wheel 1 by adding the non-return unlocking mechanism when the toy gun is not in use, thereby unlocking the gear set. Under the elastic action of the elastic piece 3, the end gear, the intermediate transmission gear 8 and the ratchet wheel 1 reversely rotate, and the elastic piece 3 rebounds and restores to be deformed.
Furthermore, a return spring is arranged on the non-return pawl 4, and before the toy gun is ready to be used, when the control mechanism moves towards the direction opposite to the direction for unlocking the ratchet wheel 1, the non-return pawl 4 is reset under the action of the return spring and acts on the driven gear again.
Further optionally, as shown in fig. 1 and 2, the backstop interaction structure includes: a guide limiting part formed at the upper end of the plate part 5, the guide limiting part including a guide inclined plane 52 and a limiting groove 51 at the bottom of the guide inclined plane 52; when the moving distance of the control machine piece is smaller than a preset distance or the rotating angle is larger than a preset angle, the interactive teeth are limited to move in the limiting groove 51; when the moving distance of the control machine piece is larger than the preset distance or the rotating angle is larger than the preset angle, the interactive teeth move towards the outer side of the limiting groove 51 along the guide inclined plane 52.
Specifically, the limiting groove 51 is formed by inward sinking of one end of the plate part 5 away from the protruding rod, and the interactive teeth are formed by downward extending of the corresponding position of the control panel and the limiting groove 51; the interactive teeth extend into the limiting groove 51, and the control mechanism moves or rotates to drive the interactive teeth to move or rotate. The plate portion 5 includes a rotating end about which the plate portion 5 is pivotally disposed. One specific embodiment of the plate portion 5 of the present embodiment is: as shown in fig. 1 to 3, 5 and 6, the plate portion 5 has a triangular-like structure, the protruding rod is located at the vertex formed by the two short sides of the triangular structure, the rotating end is located at one end of the long side of the triangular structure, the guiding slope 52 and the restricting groove 51 are located on the long side of the triangular structure, and the guiding slope 52 is located on the side of the restricting groove 51 away from the rotating end. The present embodiment can maximally simplify the structure of the plate portion 5 by providing the plate portion 5 in a triangular-like structure, saving the internal space. However, in practical use, the shape of the plate portion 5 is not limited to this, and the present invention is not limited to the specific shape of the plate portion 5. When the moving distance of the control mechanism is greater than the preset distance or the rotating angle is greater than the preset angle, the interactive teeth move to the outer side of the limiting groove 51 along the guide inclined plane 52, and move in the displacement range formed by the bottom wall of the limiting groove 51 and the guide inclined plane 52 without departing from the limiting inclined plane.
Further alternatively, as shown in fig. 1, 2 and 7, the side of the alternating teeth opposite the guide surface forms an inclined surface that cooperates with the guide ramp 52. Specifically, the inclined plane is formed by the interactive tooth and the opposite side of the guide part inclining towards the inner part of the limit groove 51, and when the moving distance of the control machine piece is greater than the preset distance or the rotating angle is greater than the preset angle, the inclined plane of the interactive tooth is in sliding contact with the guide inclined plane 52.
Further optionally, the backstop unlocking mechanism further comprises a driving part acting on the control panel to drive the control panel to move or rotate.

A push rod is connected between the upper end of the linkage block and the trigger, when the control piece moves towards the direction of unlocking the ratchet wheel 1, the control piece pushes the upper end of the linkage block to rotate around the lower end of the linkage block, the upper end of the linkage block rotates to drive the push rod to move, and the trigger is locked by the push rod to be pulled by the push rod to make the trigger unable to be pulled; when the control machine piece moves towards the direction of locking the ratchet wheel 1, the linkage block resets under the action of the reset torsion spring, at the moment, the upper end of the linkage block rotates reversely around the lower end of the linkage block to drive the push rod to move reversely to unlock the trigger, and the trigger can be pulled.
It should be noted that the interlocking relationship among the locking member, the control plate and the trigger is a known technology in the field of toy handguns, and the present embodiment drives the control plate to move to lock the trigger and unlock the ratchet 1 to reset the spring by forming a non-return interaction structure between the lower end of the existing control plate and the upper end of the plate 5; meanwhile, before the pistol is used, the reverse movement of the control mechanism piece is driven to unlock the trigger, and the non-return pawl 4 acts on the ratchet wheel 1 again, so that the use of parts is saved, and the effect of killing two birds with one stone is achieved.
The operation of the toy gun of this embodiment is explained in detail below:
when the toy pistol is in a use state, the driving mechanism drives the driving gear 7 to rotate, the driving gear 7 drives the ratchet wheel 1, the intermediate transmission gear 8 and the tail end gear to rotate, and the toothless gear 9 of the tail end gear is meshed with the rack 21 on the piston rod 2. The non-return pawl 4 is matched with the ratchet wheel 1 and used for ensuring the unidirectional running state of the ratchet wheel 1 and the gear set. When the gear 9 rotates to the position that the gear part is meshed with the rack 21, the gear 9 rotates to move towards the direction of compressing the spring through the piston rod 2, when the gear 9 rotates to the position that the gear part is opposite to the rack 21, no action is exerted between the gear 9 and the piston rod 2, the spring is released to push out the piston rod 2, and accordingly bullets are shot out, and the bullet shooting operation is repeated to form the action of continuously shooting the bullets.
When the toy pistol is not in use, the driving mechanism stops providing power for the driving gear 7, and the driving gear 7, the ratchet wheel 1, the intermediate transmission gear 8 and the end gear stop running. When the control piece is moved in the direction of locking the trigger by manually operating the driving part, the trigger is locked and cannot be pulled, and the non-return pawl 4 is separated from the ratchet 1. If the gear portion of the gear 9 with missing teeth is just in the state of meshing with the rack 21, the spring is in a compressed state, and after the non-return pawl 4 is separated from the ratchet 1, the spring is rebounded and released.
When the toy pistol is to be used, the control mechanism is moved towards the trigger unlocking direction by manually operating the driving part, the trigger is unlocked and can be pulled, the non-return pawl 4 acts on the ratchet wheel 1 again, and after the trigger is pulled, the driving mechanism is started, and the ratchet wheel 1 and the ratchet wheel group are in a one-way operation state.
Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
