The terms "vertical", "horizontal", "left", "right", and similar terms as used herein are for purposes of description only.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in this description, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0023] Referring to Figure 1 , Figure 2 and Figure 3 , the embodiment provides an insertion type anti-rotation buffer support rod, which comprises a guide rod and a guide sleeve, the guide rod is inserted into the guide sleeve, and the guide rod can be limited to slide in the guide sleeve. Specifically, the guide sleeve is divided into a first guide sleeve, a second guide sleeve and a third guide sleeve according to functions, and the first guide sleeve, the second guide sleeve and the third guide sleeve are connected in sequence and integrally formed. The first guide sleeve is the open end of the guide sleeve, and a bushing is arranged in the first guide sleeve. In the embodiment, the bushing is made of PEEK material, a hexagonal bushing limits the turning direction of the hexagonal guide rod, and the diameter of the first guide sleeve is relatively large and the wall thickness is larger, so that the buffer support rod is convenient to install and clamp during use. The diameter of the second guide sleeve is smaller than that of the first guide sleeve, and a ventilation hole is arranged in the middle of the second guide sleeve for ventilation during work. The third guide sleeve is the closed end of the guide sleeve, and a support is arranged in the third guide sleeve, the support is used for connecting a spring, the spring is used for providing support and elastic force for the guide rod during movement, and the movement range of the guide rod is limited. Two O-rings are arranged on the outer surface of the guide rod, and the O-rings are used for the movement of the guide rod in the guide sleeve.

[0024] Referring to Figure 4The buffer support rod is installed in the middle of the connecting plate, the guide sleeve penetrates the connecting plate from below, the third guide sleeve is located above the surface of the connecting plate, the length of the second guide sleeve is the same as the thickness of the second connecting plate, the first guide sleeve is located below the lower surface of the connecting plate, the other end of the guide rod is provided with a suction disc, the outer surface of the third guide sleeve is provided with threads, and a nut cover needs to be installed during use. A filter core can be installed at the bracket position to filter impurities in the gas. The upper end and the lower end of the second guide sleeve are respectively provided with a combined gasket and a nylon gasket for sealing.

[0025] The product is installed on a special mounting plate in a plug-in manner, and is fixed by sealing rings upwards and downwards. The mounting plate is provided with an air pipe in the middle, the air pipe is directly connected to the mounting plate, the air pipe and the buffer support rod are not in direct contact, thereby directly eliminating the influence of the air pipe tension on the buffer support rod, the mounting plate is provided with fixed holes at intervals, and the convenience of positioning of the buffer support rod is improved.

[0026] The inner sleeve is made of PEEK material, the hexagonal sleeve limits the turning direction of the hexagonal guide rod, the double sealing rings in the hexagonal guide rod reduce the friction between the guide rod and the inner wall of the sleeve, and the double sleeve design makes the guide rod have higher concentricity in the movement of the sleeve, and prevents the guide rod from leaking gas during operation. The product has the characteristics of long service life, low noise, low dust emission and low swing amplitude. The sleeve made of PEEK material fixes the product in the upward and downward direction, effectively limits the swing amplitude of the guide rod during sliding, improves wear resistance, and reduces dust emission.

[0027] The product is suitable for working conditions with high precision requirements for repeated positioning and high requirements for dust emission, such as 3C electronics and other industries. The PEEK material sleeve is formed by injection molding, has good consistency, the double O-ring structure of the guide rod makes the guide rod and the guide sleeve fit tightly, the guide type is good, and the swing amplitude of the buffer support rod is effectively reduced. At the same time, the excellent performance of the PEEK material can effectively reduce the dust emission during the friction of the guide rod, and the wear resistance can greatly improve the service life. When the guide rod moves in and out of the guide sleeve, the PEEK sleeve limits the swing amplitude of the guide rod, the double O-ring design makes the product have smaller friction, reduces the loss caused by friction, has higher concentricity, and thus improves the service life and quality of the product.
