Detailed Description
The first embodiment is as follows:
as shown in fig. 1 and 2, the mis-triggering prevention device for a switch mechanism in this embodiment includes a housing, a switch, and a push rod, wherein the switch is disposed in the housing, the push rod penetrates through the housing, a handle is disposed at one end of the push rod exposed out of the housing, a bottom end of the push rod in the housing is aligned with the switch, the housing is square, the housing includes a housing and a cover body, a top opening of the housing is formed, and the cover body is fastened to an upper portion of the housing; a limiting plate is arranged at the bottom end of the ejector rod close to the upper part, the limiting plate is parallel to the bottom surface of the shell, baffles and baffle grooves are arranged on the front inner wall and the rear inner wall of the shell and close to the two ends of the limiting plate, and the baffles are aligned with the middle parts of the baffle grooves;
the top surface of the shell is provided with a spring used for bouncing the pressed cover body; the middle part of the cover body is provided with a long hole, and the long hole extends towards the front and back direction of the shell and is consistent with the arrangement direction of the baffle plate and the baffle groove; the ejector rod penetrates through the long hole and can move back and forth in the long hole; the top of the ejector rod is arranged at the inner side of the cover body and close to the cover body, and a sliding plate is arranged.
As shown in fig. 3, 4, 5 and 6, when the device is used, the handle is pushed forwards, the ejector rod drives the limiting plate to move forwards, the front end of the limiting plate enters the blocking groove, and the rear end of the limiting plate is separated from the blocking of the baffle; the handle or the cover body is pressed downwards, the ejector rod and the cover body move downwards together, and the stop groove limits the ejector rod and the cover body to continue moving downwards when the front end of the limiting rod is contacted with the bottom of the stop groove; the handle is pushed backwards, the ejector rod moves backwards, and the front end of the limiting plate is separated from the blocking of the blocking groove; at this time, the push rod can move downwards without obstruction, so that the switch is triggered. The return operation of the jack is reversed as follows, and the spring helps the jack to return to the original position.
Further, the distance between the top surface of the shell and the top surface inside the cover body is smaller than or equal to the vertical stroke of the ejector rod, namely, the maximum stroke of downward movement of the cover body is smaller than or equal to the stroke of the ejector rod from the original position to the position capable of triggering the switch, therefore, the downward stroke of the cover body is limited in a certain range by the shell, the ejector rod is limited on the cover body through the handle and the sliding plate, namely, the downward stroke of the ejector rod is also limited in a certain range, and therefore the switch is protected from being excessively contacted by the ejector rod to cause damage to the switch.
Furthermore, the stroke of the ejector rod in the long hole is smaller than or equal to the sum of the length of the baffle and the depth of the baffle groove. When the ejector pin moves forward, its pole part supports the slot hole forward position, the limiting plate front end gets into and keeps off the inslot and the front end does not take place to contact with keeping off the groove lateral wall, and the limiting plate rear end just breaks away from the baffle simultaneously, and the plumb line of limiting plate rear end is separated from the plumb line of baffle front end mutually promptly, and the baffle can not lead to the fact the stopper to the limiting plate. Therefore, the stroke of the ejector rod is limited through the long hole, so that the collision between the limiting plate and the inner wall of the shell is reduced and avoided, and the operation behavior of a user can be limited through the cover body, so that the device is prevented from being damaged.
Furthermore, the handle is round or long, and the diameter of the round or the width of the long strip is larger than the length of the long hole. The handle (i.e. the mandril) and the cover body move relatively, and the cover body is kept still when the handle moves back and forth. If the width of the handle is smaller than the length of the long hole, the long hole is exposed outside after the handle moves forwards and backwards, and foreign matters enter the shell to influence the normal work of the button and the switch; on the contrary, when the handle width is greater than the length of slot hole, the handle can cover the slot hole all the time, avoids the slot hole to expose outside.
Further, a groove (not shown in the figure) is formed in the top surface of the shell, and the spring is embedded in the groove. The lid moves down, can compress the spring into the recess, and the stroke of lid rebound to the casing top can not be influenced to the height of spring itself.
Example two:
as shown in fig. 7, on the basis of the above embodiments, the bottom surface of the baffle and/or the top surface of the retaining groove in this embodiment are inclined surfaces. According to the use method, when the ejector rod is restored to the original position, the handle needs to be manually pushed forwards and backwards to enable the limiting plate to be separated from the baffle and the bottom surface of the blocking groove (the top surface of the blocking groove and the bottom surface of the baffle are collectively called as the bottom surface), and operation is inconvenient. The bottom surface design of this embodiment is the inclined plane, and when the lid was held up by spring force, the limiting plate both ends can be automatic along the snakelike upward movement of the bottom surface of slope, made the ejector pin resume the normal position to the next time trigger of convenient button. Furthermore, the edges of the baffle plate, the baffle groove and the two ends of the limiting plate can be treated as fillet transition, so that the limiting plate (namely the ejector rod) can move upwards more smoothly and freely.
Example three:
as shown in fig. 8, in addition to the above embodiments, two ends or one end of the limiting plate of the present embodiment are bent downward to form locking portions; the baffle plate is inclined upwards; the upward inclined angle of the baffle is equal to the bending angle of the tail end of the limiting plate; the handle is provided with an open-loop or closed-loop handle. This embodiment can effectively avoid pushing the handle back and forth because of the operation of non-subjective consciousness and mistake, causes the false triggering of switch. When the push rod is used, the handle is required to be moved upwards through the lifting handle, the locking part is separated from the baffle which is inclined upwards, then the handle is pushed forwards, and the push rod is operated according to the method. Similarly, the bottom surface of the baffle groove can be inclined according to the arrangement method of the baffle plate, and the locking part at the tail end of the limiting plate at the same side is matched, so that misoperation can be prevented for the second time.
Further, the bending angle of the locking part is 10-90 degrees.
Example four:
as shown in fig. 9, on the basis of the above embodiments, the baffle and the locking portion of the present embodiment are both L-shaped, and the baffle and the locking portion are fastened together. Compared with the locking part and the baffle plate which are arranged obliquely, the baffle plate in the L shape with the right angle can effectively prevent misoperation, and the possibility that the inclined surface is triggered by mistake under extreme conditions can be completely avoided. Similarly, the bottom surface of the baffle groove can be designed into an L shape according to the arrangement method of the baffle plate, and the locking part buckled with the tail end of the limiting plate on the same side is matched, so that misoperation can be prevented for the second time.
Example five:
on the basis of the above embodiment, the middle part of the cover body is provided with the rotating disc, that is, the long hole is installed on the cover body through the rotating disc, so that the direction of the long hole can be adjusted; when the direction of the long hole is not consistent with the pushing direction of the handle, especially when the long hole and the pushing direction are vertical to each other, the cover body can prevent the handle from moving forwards so as to limit possible false triggering.
Further, the rotation angle of the rotary disc on the cover body can be limited within a certain angle range, preferably 90 degrees, namely when the rotary disc (long hole) rotates to the direction consistent with the pushing direction of the handle, the rotary disc (long hole) is 0 degree, at the moment, the handle can be normally pushed forwards, and therefore the button is triggered; when the turntable is rotated to be perpendicular to the pushing direction of the handle (90 degrees), the button can not be triggered.
Furthermore, a torsion spring is arranged between the turntable and the cover body, when the torsion spring is not pressed by external force, the turntable is rotated to a 90-degree (vertical) state, and the handle cannot be pushed forwards without operating the turntable.
Furthermore, a wrench is arranged on the rotary disc, the rotary disc is rotated by pushing the wrench to adjust the direction of the long hole, and the button is triggered.
Finally, it should be noted that the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting, and although the present invention has been described in detail with reference to examples, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, which should be covered by the claims of the present invention.
