Detailed Description
The present utility model will be further described with reference to the accompanying drawings and detailed description, wherein it is to be understood that, on the premise of no conflict, the following embodiments or technical features may be arbitrarily combined to form new embodiments.
Examples
Referring to fig. 1 to 3, two different embodiments of the negative pressure suction cup of the present utility model are shown, each of which includes a suction cup cover 100, a check valve 200, a pressing telescopic mechanism 300, and a trigger lever 400. The suction cup cover body 100 is provided with an opening end, and the opening end is provided with a sealing skirt edge 110 for preventing gas from leaking from the opening end after the suction cup cover body 100 is contacted with an object, and two fluid channels penetrating through the suction cup cover body 100 body are arranged in the suction cup cover body 100, namely a first channel 120 and a second channel 130; the check valve 200 is installed in the first passage 120 to control the fluid in the suction cup housing 100 to flow unidirectionally to the outside of the suction cup housing 100; the telescopic end of the push telescopic mechanism 300 can extend into and out of the second channel 130; the trigger lever 400 is used for triggering the telescopic end of the pressing telescopic mechanism 200 to stretch, so as to control the telescopic end of the pressing telescopic mechanism 300 to stretch into and stretch out of the second channel 130, and control the switch of the second channel 130.
The suction cup housing 100 deforms and abuts against an object after being squeezed, which is a conventional configuration of suction cup devices, and many specific embodiments are not described in detail herein.
The push retraction mechanism 300 of the present utility model is well known in the art, such as a conventional ball point pen retraction mechanism, and many embodiments are possible and will not be described in detail herein.
When the sucker cover body 100 is used, firstly, the sucker cover body 100 is contacted with an object, then, the trigger rod 400 is used for pressing the pressing telescopic mechanism 300, so that the telescopic end of the pressing telescopic mechanism 200 stretches into the second channel 130 to close the second channel 130, as shown in fig. 2, in the process, the sucker cover body 100 is deformed, the volume of a cavity between the sucker cover body 100 and the object is reduced, and the gas in the cavity is discharged through the first channel 120, so that the sucker cover body 100 and the object are connected into a whole; after reaching the target position, the pressing telescopic mechanism 300 is pressed again by the trigger lever 400, so that the telescopic end of the pressing telescopic mechanism 200 is separated from the second channel 130, as shown in fig. 1, thereby opening the second channel 130, and then gas enters the cavity between the suction cup cover 100 and the object from the second channel 130, and the suction cup cover 100 is separated from the object, thereby unloading the object. In the whole process, only the pressing operation of the trigger lever 400 is needed, different valves do not need to be opened in a circulating way, and the operation is very simple and convenient.
In one embodiment of the present utility model, the trigger lever 400 may be fixedly connected to the pressing end of the pressing telescopic mechanism 300, as shown in fig. 3, and moving the trigger lever 400 may drive the object absorbed by the suction cup cover 100 to move.
In one embodiment of the present utility model, the present utility model further includes a guide cylinder 500 fixedly connected to the suction cup cover 100, and the trigger lever 400 is slidably connected to the guide cylinder 500 via a guide mechanism for guiding the trigger lever 400 to move axially along the guide cylinder 500. The specific guiding mechanism may be a cross-shaped frame fixed on the outer wall of the triggering lever 400, and of course, the triggering lever 400 and the guiding cylinder 500 may also be directly connected in a spline manner. In addition, the guide cylinder 500 is also provided with a limiting mechanism 600, and the limiting mechanism 600 may be a baffle ring in threaded connection with the inner wall of the guide cylinder 500, so as to limit the range of movement of the trigger lever 400 along the axial direction of the guide cylinder 500, and prevent the trigger lever 400 from being separated from the guide cylinder 500.
