Description

Technical Field

[0001] This utility model relates to the field of large air cannon switch connector technology, and in particular to a large air cannon switch connector that prevents detachment. Background Technology

[0002] A pneumatic wrench is a pneumatic tool powered by compressed air. Its full name is "pneumatic impact wrench". It is named for the strong impact force and obvious "pneumatic noise" that it produces when working, which is similar to the sound of a cannon.

[0003] A large air jet connector is an accessory used in large air jet equipment. It primarily connects the air hose and the large air jet, enabling quick connection and disconnection of the air source and controlling the flow of air. Air jet connectors typically use male and female connectors, with automatic locking achieved through a mechanical snap-fit / spring return mechanism during connection. When the pneumatic wrench is in operation, it will vibrate. The unlocking ring on the outside of the female head, which is elastically connected by a spring, will shake with the vibration of the pneumatic wrench. This will result in poor tightness between the internal steel column and the outer wall groove of the male head. There is a risk that the male and female heads will fall off when the pneumatic wrench is in operation. Utility Model Content

[0004] Therefore, it is necessary to provide a large air gun switch connector that prevents detachment, addressing the problem that the air gun vibrates during operation, causing the unlocking ring to shake with the vibration, resulting in poor tightness between the internal steel column and the outer wall groove of the male connector, and the risk of the male and female connectors falling off.

[0005] A large air cannon switch connector for preventing detachment includes: a connector body, which internally consists of a female head, a male head, and an unlocking ring, wherein the male head is inserted into the end of the female head, and the unlocking ring is sleeved on the outside of the female head; An anti-detachment mechanism includes a fixed ring, a lifting ring, and a rotating ring. The fixed ring is fixedly sleeved on the outer arc surface of the bottom end of the unlocking ring. The rotating ring is rotatably sleeved on the outside of the female head. A threaded ring is sleeved on the outside of the female head above the rotating ring. The lifting ring is sleeved on the outside of the threaded ring. The inner wall of the lifting ring that is in contact with the threaded ring has a threaded groove corresponding to the external thread of the threaded ring. The top end of the lifting ring is provided with multiple top posts for supporting the fixed ring that is fixedly installed on the outside of the bottom end of the unlocking ring.

[0006] In one embodiment, the bottom surface of the fixing ring has a notch corresponding to the top of the top post, and the top of the top post abuts against the inner wall of the notch.

[0018] The following is combined with Figures 1-7 This invention describes the anti-fall-off switch connector for a large air cannon.

[0019] In one embodiment, a large air cannon switch connector for preventing detachment includes: a connector body 100, which is internally composed of a female connector 101, a male connector 102 and an unlocking ring 103, wherein the male connector 102 is inserted into the end of the female connector 101 and the unlocking ring 103 is sleeved on the outside of the female connector 101. Additional notes: The model of the connector body 100 in this application can be: C-type self-locking quick connector series, such as 20SF internal thread NPT1 / 4; It includes, but is not limited to, the following structures: connector body 100, self-locking mechanism, sealing components, and protective collar; The anti-detachment mechanism 200 includes a fixed ring 201, a lifting ring 202, and a rotating ring 203. The fixed ring 201 is fixedly sleeved on the outer arc surface of the bottom end of the unlocking ring 103. The rotating ring 203 is rotatably sleeved on the outside of the female head 101. A threaded ring 205 is sleeved on the outside of the female head 101 above the rotating ring 203. The lifting ring 202 is sleeved on the outside of the threaded ring 205. The inner wall of the lifting ring 202 that is in contact with the threaded ring 205 has a threaded groove 204 corresponding to the external thread of the threaded ring 205. The top end of the lifting ring 202 is provided with multiple top posts 208 for supporting the fixed ring 201 fixedly installed on the bottom end of the unlocking ring 103. like Figure 3 , Figure 4 and Figure 5 As shown, the bottom surface of the fixing ring 201 has a notch 209 corresponding to the top of the top post 208, and the top of the top post 208 abuts against the inner wall of the notch 209. In this embodiment, when the rotating ring 203 rotates and drives the lifting ring 202 to rise, the end of the top post 208 provided at the top of the lifting ring 202 moves toward the bottom of the fixed ring 201, so that the end of the top post 208 abuts against the inner wall of the notch 209 opened on the bottom surface of the lifting ring 202. The top post 208 supports the unlocking ring 103 fixedly installed with the fixed ring 201, so as to prevent the unlocking ring 103 from shaking under the vibration generated by the use of the air gun, which would cause the steel ball inside the female head 101 to fall out of the slot on the side wall of the male head 102, causing the male head 102 and the female head 101 to fall off. like Figure 3 , Figure 4 and Figure 5 As shown, the outer arc surface of the female head 101 is provided with multiple guide grooves 210, and a protrusion 211 is slidably arranged inside the guide groove 210. The protrusion 211 is fixedly installed with the inner wall of the lifting ring 202. The guide groove 210 is located between the unlocking ring 103 and the rotating ring 203. In this embodiment, when the lifting ring 202 is driven to move upward by the rotating ring 203, the protrusion 211 fixedly provided on the inner wall of the lifting ring 202 moves upward along the inside of the guide groove 210. The guide groove 210 guides and limits the protrusion 211 to prevent the lifting ring 202 from rotating along with the rotating ring 203. like Figure 3 and Figure 4 As shown, the outer arc surface of the female head 101 is provided with a groove 206, and the inner wall of the rotating ring 203 that contacts the female head 101 is provided with a retaining ring 207, which is slidably connected to the inner wall of the groove 206. In this embodiment, a groove 206 is provided on the outer arc surface of the female head 101, and a retaining ring 207 provided on the inner wall of the rotating ring 203 is rotatably disposed inside the groove 206. The retaining ring 207 limits the rotation of the rotating ring 203, preventing the rotating ring 203 from moving up and down along the outer arc surface of the female head 101 when it rotates. like Figure 2 , Figure 3 and Figure 4 As shown, the outer arc surface of the rotating ring 203 is provided with several vertical anti-slip strips; In this embodiment, several vertical anti-slip strips are provided on the outer arc surface of the rotating ring 203 to increase the friction between the user's hand and the rotating ring 203; like Figure 6 and Figure 7 As shown, the bottom surface of the rotating ring 203 is located outside the female head 101 and a lower edge ring 212 is provided. The outer arc surface of the lower edge ring 212 is threaded with multiple fastening bolts 213. The end of the fastening bolt 213 that passes through the lower edge ring 212 is provided with a butt 214. The butt 214 is in close contact with the outer arc surface of the female head 101. The outer arc surface of the female head 101 that contacts the abutment 214 is provided with anti-slip texture, and the abutment 214 is made of rubber. In this embodiment, a lower edge ring 212 is provided at the bottom end of the rotating ring 203. A fastening bolt 213 is threaded onto the outer arc surface of the lower edge ring 212. A butt 214 is provided at the end of the fastening bolt 213 that passes through the outer arc surface of the lower edge ring 212. The butt 214 is in close contact with the outer arc surface of the female head 101. The outer arc surface of the female head 101 that contacts the butt 214 is provided with anti-slip texture to increase the friction between the butt 214 and the outer arc surface of the female head 101 and ensure the stability of the fastening bolt 213 when fixing the lower edge ring 212. Working principle: When in use, insert the bottom end of the male head 102 into the top end of the female head 101. The male head 102 is fixed by the snap-fit ​​structure inside the female head 101. Release the unlocking ring 103 so that the unlocking ring 103 is reset under the action of the internal spring. Connect the bottom end of the female head 101 to the air gun and the end of the male head 102 to the pipe. After installation, the user manually rotates the rotating ring 203 to drive the lifting ring 202 to rise, so that the end of the top post 208 on the top surface of the lifting ring 202 is in close contact with the bottom surface of the fixing ring 201. Then, the user stops rotating the rotating ring 203 and uses a tool to tighten the fastening bolt 213 downwards along the ring 212, so that the abutment 214 at the end of the fastening bolt 213 is in close contact with the protective texture on the outer arc surface of the female head 101. The fastening bolt 213 is used to fix the lower ring 212, thereby fixing the rotating ring 203. This ensures that the rotating ring 203 does not rotate due to vibration during the use of the air hammer, and prevents the top post 208 from being in close contact with the bottom surface of the fixing ring 201, thus preventing the unlocking ring 103 from being reinforced and prevented from falling off.
