Description

Technical Field

[0001] The utility model relates to the technical field of needle suction cups, in particular to a needle suction cup with strong adsorption force. Background Art

[0002] A needle suction cup with strong adsorption force is a device that uses multiple steel needle tips to contact the surface to generate adsorption force, and is usually used to create local vacuum on smooth or irregular surfaces to fix or position objects. Its design includes a knob for adjusting the adsorption force, an air inlet for forming and releasing vacuum, and a sliding component for controlling the lifting of the needle seat to adapt to objects of different thicknesses. With the characteristics of strong adsorption force and quick release, the needle suction cup has a wide range of applications in process processing, device fixing and precision operation and other occasions.

[0003] In the prior art, most of the needle suction cups with strong adsorption force have only one rate. The needle suction cup that cannot adjust the adsorption rate may face problems of limited operability and insufficient adaptability during use. When fine control of the adsorption speed of the suction cup on the object is required, the suction cup with a fixed rate may generate strong adsorption force too quickly, thus damaging fragile objects, or may not provide sufficient control when slow and stable adsorption is needed, resulting in difficult operation and reduced flexibility. Therefore, in view of the above deficiencies, a needle suction cup with strong adsorption force is proposed. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art, and to propose a needle suction cup with strong adsorption force, aiming to improve the problem that the adsorption rate cannot be adjusted according to different needs in the prior art, resulting in reduced flexibility of the device.

[0020] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] Refer to Figure 1 - Figure 3, an embodiment provided by the present utility model: a needle-type suction cup with strong adsorption force, including a housing 12, which is designed to provide a structural basis and protect internal components. An adsorption air inlet 1 is provided at the top right end of the housing 12. This air inlet allows air to enter, thereby forming a negative pressure to generate an adsorption force. A downward pressure chamber 2 is provided inside the top end of the housing 12. This is a specific space for storing air when the piston plate 3 is pressed down. A sliding assembly is provided at the top end of the housing 12. This assembly is a key part of the suction cup function and allows the piston plate 3 to move inside. The sliding assembly includes a piston plate 3, whose outer part is slidably connected to the inner wall of the top end of the housing 12 to ensure smooth movement. The outer part of the piston plate 3 is slidably connected to the inner wall of the top end of the housing 12. A piston connecting rod 6 is fixedly connected to the bottom side of the piston plate 3. This connecting rod transmits the movement of the piston plate 3 to other parts of the suction cup;

[0022] A needle seat stopper 9 is fixedly connected to the bottom side of the sliding assembly. It supports the steel needles 10 and keeps their positions. The outer part of the piston connecting rod 6 is slidably connected to the inner wall of the housing 12, ensuring the stability and accuracy of the connecting rod. The bottom side of the piston connecting rod 6 is fixedly connected to the top side of the needle seat stopper 9. In this way, when the connecting rod moves, the needle seat stopper 9 will also move accordingly. An upward lift chamber 4 is provided at the top of the housing 12. This is a space for storing air when the piston plate 3 is lifted. The outer part of the needle seat stopper 9 is slidably connected to the inner wall of the housing 12, ensuring that the needle seat stopper 9 can move up and down smoothly. The outer part of the piston plate 3 is slidably connected to the inside of the upward lift chamber 4, which allows the piston plate 3 to move between different positions to control the function of the suction cup;

[0023] A release air inlet one 5 is provided at the top right end of the housing 12. This air inlet is used to allow air to enter the inside of the housing 12 when it is necessary to release the adsorption. A quick release air inlet two 7 is provided in the middle right end of the housing 12. This is another air inlet for quickly releasing the adsorption state of the suction cup. A quick release air passage 8 is provided at the bottom right end of the housing 12. This is a passage for quickly discharging the air inside the housing 12 to quickly release the suction cup. A plurality of steel needles 10 are fixedly connected to the bottom side of the needle seat stopper 9. These steel needles 10 are the key parts of the contact surface of the suction cup and generate the adsorption force. An adjustment knob 11 is provided in the middle of the front side of the adsorption air inlet 1. This knob is used to manually adjust the adsorption force of the suction cup to meet different usage requirements.

[0024] Working principle: Compressed air is introduced into the adsorption air inlet 1, and no compressed air is introduced into the release air inlet 1-5. The compressed air enters the lower pressure chamber 2, pushing the piston plate 3 to move downward. The piston plate 3 drives the piston connecting rod 6 and the needle seat block 9 to press down, causing the steel needle 10 to extend and realizing adsorption. The stroke of the steel needle 10 can be controlled by the adjustment knob 11. Compressed air is introduced into the release air inlet 1-5 while the compressed air introduced into the adsorption air inlet 1 is cut off. The compressed air enters the upper lift chamber 4, pushing the piston plate 3 to move upward. The piston plate 3 drives the piston connecting rod 6 and the needle seat block 9 to lift, causing the steel needle 10 to retract and realizing release. For rapid release, compressed air needs to be introduced into the rapid release air inlet 2-7. The compressed air reaches the steel needle 10 through the rapid release air passage 8, realizing rapid release, thereby improving the adsorption effect. Different release rates are faced with different situations, and the release speed of the steel needle 10 is adjusted, thereby improving the flexibility of the device.

[0025] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
