Problems solved by technology

With the gradual popularization of electric push rods in household, transportation, medical and other fields, the existing performance can no longer meet the increasingly rich needs
A general-purpose electric push rod can reciprocate to extend or retract, but its reciprocating stroke is generally fixed, that is to say, a fixed model of electric push rod can only reciprocate within a fixed range. In some occasions, different effects can only be achieved by replacing different push rods. The disassembly and assembly are cumbersome, time-consuming and laborious, which greatly limits the universality of the push rod

specific Embodiment 1

[0030] Such as figure 1As shown, this specific embodiment discloses a travel limit adjustment device for a push rod, including a guide rail 10 for guiding the push rod 50 and a first switch seat 21 and a second switch seat 21 movably arranged on the guide rail 10 The distance between the switch base 22 , the first switch base 21 and the second switch base 22 along the moving direction of the push rod 50 is adjustable. A first switch (not shown in the figure) is fixedly arranged on the first switch seat 21 , and a second switch (not shown in the figure) is fixedly arranged on the second switch seat 22 . The push rod 50 is provided with a first trigger 31 for triggering the first switch and a trigger for triggering the second switch. Driven by the push rod 50, the first trigger 31 and the second trigger 32 trigger the first switch respectively. and the second switch. Wherein, the first switch has a first trigger handle, the second switch has a second trigger handle, and both t...

specific Embodiment 2

[0039] This specific embodiment discloses another stroke limit adjusting device of a push rod, the structure of which is basically the same as that of the specific embodiment 1, except that the trigger information sent by the two triggers in the two embodiments is different. In the first specific embodiment, the two triggers send and receive trigger information by contacting the trigger handles of the two switches respectively. In this specific embodiment, the trigger does not need to be in direct contact with the switch. information to send and receive trigger information.

[0040] In this specific embodiment, the first switch has a first sensor, the second switch has a second sensor, the first trigger is provided with first identification information, and the second trigger is provided with second identification information. When the first trigger moves to the first switch, the first sensor recognizes the first identification information and turns on the first switch, turns ...

specific Embodiment 3

[0042] This specific embodiment discloses another stroke limit adjustment device for a push rod, its structure is basically the same as that of the specific embodiment 1, the difference is that the specific embodiment 1 uses two triggers to trigger two switches respectively, and the In this embodiment, a trigger is used to move between the two switches, thereby triggering the two switches respectively.

[0043] In this specific embodiment, the stroke limit adjusting device of the push rod includes a trigger fixedly arranged on the push rod, and the trigger moves between the first switch and the second switch driven by the push rod. Specifically, the first switch has a first trigger handle, the second switch has a second trigger handle, and both the first trigger handle and the second trigger handle extend into the guide rail.

[0044] When the trigger moves to the first switch, the trigger contacts the first trigger handle, the trigger sends the third trigger information, the ...

Abstract

The invention discloses a stroke limit adjustment device for a push rod, which comprises a guide rail, a first switch seat and a second switch seat movably arranged on the guide rail, a first switch arranged on the first switch seat, a second switch arranged on the second switch seat and a trigger fixedly arranged on the push rod. When the trigger is moved to the first switch, the trigger sends triggering information, the first switch is on, the second switch is off, and the push rod moves towards a first direction. When the trigger is moved to the second switch, the trigger sends triggering information, the second switch is on, the first switch is off, and the push rod moves towards a second direction opposite to the first direction. The stroke limit adjustment device for the push rod can be improved on the basis of a commonly-used electric push rod, the universality is strong, the structure is compact, the operation is convenient, the stroke adjustment range is wide, and the adjustment precision is high.

Description

technical field [0001] The invention relates to the technical field of performance improvement of a push rod device, in particular to a stroke limit adjustment device of a push rod. Background technique [0002] The electric push rod is an electric drive device that converts the rotary motion of the motor into the linear reciprocating motion of the push rod. It can be used as an executive mechanism in various simple or complex processes to achieve remote control, centralized control or automatic control. control. With the gradual popularization of electric actuators in household, transportation, medical and other fields, the existing performance can no longer meet the increasingly rich needs. A general-purpose electric push rod can reciprocate to extend or retract, but its reciprocating stroke is generally fixed, that is to say, a fixed model of electric push rod can only reciprocate within a fixed range. In some cases, different effects can only be achieved by replacing d...
