Example 1

As shown in FIG. 1 to FIG. 5 , this embodiment provides a detection device for amplifying the triggering distance, including: a fixing frame 1 , a reset buffer elastic device 2 , a transverse rod 3 , a transmission shaft 4 , a hinge shaft 5 , a longitudinal rod 6 , Inductive parts 7, detection switches 8 and other components;

Among them, the fixing frame 1 is provided with horizontal through holes, longitudinal through holes, threaded holes and other structures, and is the mounting frame of each component, which can also facilitate the installation of the detection device on the equipment using the detection device, such as amusement equipment or other devices.

The transverse rod 3 is installed in the transverse through hole of the fixing frame 1, and the transverse rod 3 cooperates with the transverse through hole of the fixing frame 1 to form a transverse linear moving pair. The plane on one side of the fixed frame 1 maintains a constant value L1 distance dimension, this distance is the trigger distance for applying the external force F.

The longitudinal rod 6 is installed in the longitudinal through hole of the fixing frame 1 through the hinge shaft 5, the longitudinal rod 6 cooperates with the fixing frame 1 through the hinge shaft 5 to form a rotating pair, and the installation hole connecting the longitudinal rod 6 and the hinge shaft 5 deviates from the longitudinal direction. At the center position of the rod 6, two parts of a long rod and a short rod are formed on the longitudinal rod 6. The distances from the installation hole to the two ends are M and N respectively, and M is the length of the long rod, that is, the length from the installation hole to the connection sensor 7, N is the length of the short rod body, that is, the length from the mounting hole to the transmission shaft 4 used to connect the transverse rod 3, and M ratio N forms a certain proportional relationship.

The longitudinal rod 6 is provided with a long hole at one end of the short rod body. The transverse rod 3 is matched with the long hole of the longitudinal rod 6 through the transmission shaft 4 to connect the two. The transverse rod 3 is connected to the hinge shaft 5 and the longitudinal rod. 6 constitutes a moving guide rod mechanism; when the lateral rod 3 moves a distance L1 under the action of the external force F, the end of the long rod body of the longitudinal rod 6 connected to the induction member 7 swings a certain angle B and runs a displacement L2 of L1×M÷N , as the amplification trigger distance, since M is greater than N, L2 as the amplification trigger distance must be greater than L1, thereby realizing the amplification of the trigger distance L1, satisfying the trigger distance and improving the sensitivity of the detection device. Since the maximum moving dimension L1 of the transverse rod 3 is a fixed value, when the value of M is larger than the N value, the larger the value of the rotation angle B and the displacement dimension L2 of the longitudinal rod 6 is, the more sensitive the detection device is. The detection device can be widely used in the field of amusement facilities and other fields of work.

The detection switch 8 can be installed on the fixing frame 1 by bolt connection, and can be installed on either side of the sensing element 7 connected by the longitudinal rod 6 according to the functional requirements. The specific position depends on the rotation angle B of the longitudinal rod 6 and It is determined by running the displacement dimension of L1×M÷N, as long as the induction member 7 connected with the longitudinal rod 6 maintains a distance that can be triggered smoothly; the induction member 7 can be bolted and installed on the longitudinal rod 6 The bottom end of the long rod body, this end is used as the sensing end.

When the external force F is removed, the reset buffer elastic device 2 resets the transverse rod 3 and the longitudinal rod 6, so that the detection device performs the next external equipment detection work.

The detection device provided in this embodiment belongs to a single position detection device because the transverse rod 3 is provided with only one external contact trigger end, and only one detection switch 8 is also provided.
