Preferably, the locking member is a locking bolt.
Preferably, the outer side surface of the shell is provided with scale marks extending along the axial direction of the push rod assembly, and the first limit switch and the second limit switch are both provided with indicating signs pointing to the scale marks.
Preferably, the trigger component is a sleeve ring sleeved on the push rod, and the first limit switch and the trigger button of the second stroke are positioned in the shell and contacted by the sleeve ring.
Preferably, the first limit switch and the second limit switch are both integrally formed with sliding blocks.
The utility model has the advantages that: the first limit switch and the second limit switch can adjust the position in the sliding groove, so that the positions of the folding position and the extending position of the push rod can be adjusted as required; the locking piece can lock and fix the adjusted first limit switch and the second limit switch, and the distance between the first limit switch and the second limit switch after locking is the moving range of the push rod; therefore, the utility model provides a push rod motor has the stroke adjustable, uses the high characteristics of flexibility.
Drawings
Fig. 1 is a schematic view of a stroke adjustment structure of a push rod motor provided in this embodiment;
fig. 2 is an enlarged view of a portion a in fig. 1.
Detailed Description
The stroke adjusting structure of the push rod motor of the present invention is further described with reference to fig. 1 to 2.
The utility model provides a stroke control structure of push rod motor, includes casing 1 and sets up the push rod subassembly in casing 1, and the push rod subassembly includes lead screw, nut cover and push rod 6, and the lead screw is connected with the motor and cooperates with the thread bush, and the nut cover is fixed in the tip of push rod 6, and push rod sliding fit is in casing 1 and the cover is established on the lead screw, and the push rod subassembly is prior art, and this embodiment does not describe in detail. The method is characterized in that: the stroke adjusting structure of the push rod motor further comprises a first limit switch 2, a second limit switch 3 and a trigger component 7. The trigger component 7 is arranged on the push rod 6 of the push rod component and moves along with the push rod. The outer surface of the shell 1 is provided with a sliding groove 11 extending along the axial direction of the push rod assembly, the first limit switch 2 and the second limit switch 3 are in sliding fit in the sliding groove 11, the trigger buttons 21 of the first limit switch 2 and the second limit switch 3 are located on the moving edge of the trigger component 7 and can be contacted and triggered by the trigger component 7, and locking pieces 4 are arranged on the first limit switch 2 and the second limit switch 3. In the embodiment, the first limit switch 2 and the second limit switch 3 are both travel switches.
Based on the structure, the first limit switch and the second limit switch can slide in the sliding groove 11 to adjust the position, so that the positions of the folding position and the extending position of the push rod can be adjusted as required; the locking piece 4 can lock and fix the adjusted first limit switch and the second limit switch, and the distance between the first limit switch and the second limit switch after locking is the moving range of the push rod; when the push rod drives the trigger part to move to the first limit switch or the second limit switch, the end part of the trigger part is contacted with the corresponding trigger button and triggers the first limit switch or the second limit switch so as to control the motor to stop running in the same direction; therefore, the utility model provides a push rod motor has the stroke adjustable, uses the high characteristics of flexibility.
Specifically, retaining member 4 is the locking bolt, has the body of rod male locating hole that supplies the locking bolt on first limit switch 2 and second limit switch 3, and the cross-section of spout 11 is T type structure. When the first limit switch 2 or the second limit switch 3 needs to be locked, the locking bolt is screwed down, so that the head of the locking bolt is tightly attached to the notch wall of the sliding groove 11; when the positions of the first limit switch 2 and the second limit switch 3 need to be moved, the locking bolt is unscrewed.
