Description
Technical Field
The invention relates to a table disc launching device.
Background
The energy storage mechanism is a core component of the ejection device, and the spring energy storage is one of three energy storage modes, and is the most common mode in the ejection device. Spring accumulators use the compression and extension of springs to store and release hydraulic energy. The accumulator has the characteristics of simple structure and sensitive response. Firing impacts are an important element of many machines.
The ratchet mechanism is a unidirectional intermittent motion mechanism consisting of a ratchet and a pawl. Ratchet mechanisms are commonly used in various machine tools and automata for intermittent feeding or indexing of rotary tables, and also commonly used in jacks. Ratchet mechanisms are used for unidirectional drive in bicycles and are commonly used in hand winches to prevent reverse rotation. The ratchet wheel teeth are usually one-way teeth, the pawl is hinged on the rocker, and when the rocker swings anticlockwise, the driving pawl is inserted into the ratchet wheel teeth to push the ratchet wheel to rotate in the same direction; when the rocker swings clockwise, the pawl slides over the ratchet wheel, and the ratchet wheel stops rotating. To ensure that the ratchet does not reverse, a backstop pawl is often added to the stationary member. The size of the stroke can be adjusted by changing the structural parameters of the driving mechanism or the position of the tooth shielding cover, and the like, and can also be adjusted in the running process.
At present, a toy gun is usually launched by spring energy storage in the launching process. However, the toy gun in the general market is instantly launched, the spring is compressed to a certain degree and then is released, and the spring potential energy stored before is immediately released, so that the ejection action is completed. In the process, an operator can only determine the kinetic energy available to the object to be emitted by means of hand feeling, and the kinetic energy is very rough and has large error. This requires the ejector to give feedback to the operator to determine the exact amount of kinetic energy released.

The operating rod, the rack and the striking rod are all horizontally arranged, the teeth of the rack are kept upwards, and the rack can be pulled outwards along the direction of the outer end of the operating rod in the meshing state of the rack and the unidirectional pawl.
The release device is a stretching connecting piece, one end of the stretching connecting piece penetrates through the mounting through hole of the shell and then is connected with the engagement section of the pawl, and the other end of the stretching connecting piece is used as a stretching end and falls out of the shell.
The release device is a pull rope.
The supporting seat comprises a base, a connecting pin and a tray, wherein the base is fixedly connected with the horizontally arranged tray through the connecting pin, and the outer diameter of the base and the outer diameter of the tray are both larger than the outer diameter of the connecting pin, so that the lower part of the supporting seat is clamped into a sliding groove on the mounting surface, and the sliding connection of the supporting seat and the mounting surface is realized.

The invention changes the ratchet mechanism into a rack, the two ends of the rack are connected with the striking rod and the operating rod, and the rack is designed into one-way teeth, thereby ensuring the one-way movement in the pulling process, and simultaneously ensuring that the striking rod cannot pop up due to the elasticity of a spring under the condition that the operating rod is not applied with force.
The invention aims to solve the ejection problem and also improves the pawl. Because the device is required to achieve both the force storage function and the launching function, a movable pawl is required. The engagement section of the pawl is perforated and connected with an external trigger by a pull rope. The trigger is pressed, the pawl is lifted away from the rack by the pull rope, and the potential energy of the spring is released, so that the ejection function is realized.
Since the rack may generate a component in the vertical direction due to improper operation of the operating lever when moving, the contact point of the pawl and the rack is offset, and thus a good braking effect cannot be achieved. In order to solve the problem, the baffle plate which is thickened at a certain height in the cavity is used for limiting, and the baffle plate is an acrylic plate. Thus, good braking effect can be kept all the time while unidirectional movement is performed.
The invention has the beneficial effects of providing the rolling processing supporting device which has the advantages of relatively simple structure, lower cost, convenient installation, flexible adjustment and high strength and rigidity.
