Detailed Description of the Embodiment

[0019] The following further describes the present application in detail with reference to the Figures 1-3 drawings.

[0020] The embodiment of the present application discloses an anti-blocking short oil needle. Refer to Figures 1-3, A clog - proof short oil needle, comprising an installation base 1 and a needle body 2. A connecting pipe 3 is fixedly connected to the top end of the installation base 1. A pair of limiting grooves 10 are provided on the connecting pipe 3; a pair of clamping grooves 4 are provided on the connecting pipe 3, and the two clamping grooves 4 are respectively communicated with the limiting grooves 10. The clamping grooves 4 and the limiting grooves 10 are on the same horizontal plane. A sealing groove 9 is provided inside the connecting pipe 3, and a pair of internal grooves 8 are provided on the inner wall of the connecting pipe 3; further comprising a connecting mechanism, the connecting mechanism is installed on the needle body 2 through a sleeving ring 11 in the connecting mechanism for stably connecting the installation base 1 and the needle body 2.

[0021] In this embodiment, as Figures 1 to 3 shown, the connecting mechanism further comprises a screwing cap 5 sleeved on the needle body 2. The outer surface of the connecting pipe 3 is provided with threads that are screwed with the screwing cap 5. The screwing cap 5 can slide on the needle body 2. A pair of second clamping blocks 7 are fixed to the bottom of the sleeving ring 11. External threads that match the threads on the connecting pipe 3 are provided on both of the two second clamping blocks 7. The second clamping blocks 7 are adapted to the limiting grooves 10. An internal block 12 is fixedly connected to the bottom of the second clamping block 7. The internal block 12 is adapted to the internal groove 8. A pair of first clamping blocks 6 are fixed to the outer surface of the needle body 2. By translating or rotating the sleeving ring 11, the first clamping blocks 6 can be made to fit or separate from the second clamping blocks 7.

[0022] The first clamping blocks 6 are adapted to the clamping grooves 4. An internal block 12 is fixedly connected to the bottom of the first clamping block 6. The clamping grooves 4, the first clamping blocks 6, the second clamping blocks 7, the internal grooves 8 and the internal blocks 12 are all arc - shaped structures. An embedding pipe 14 is fixedly connected to the bottom end of the needle body 2. The embedding pipe 14 can be inserted into the central cavity of the installation base 1. The diameter of the embedding pipe 14 is smaller than the diameter of the needle body 2. A sealed connection part 13 is formed at the connection part between the embedding pipe 14 and the needle body 2. The sealed connection part 13 is adapted to the sealing groove 9.

[0023] During installation and connection, since the sleeving ring 11 is slidably connected to the needle body 2, pull up the sleeving ring 11 and the screwing cap 5, and then make the two first clamping blocks 6 respectively embed at the bottom of the limiting grooves 10. At this time, the embedding pipe 14 is inserted into the central cavity of the installation base 1. Subsequently, rotate the needle body 2 clockwise. During the rotation process, the first clamping blocks 6 slide in the limiting grooves 10, and the internal blocks 12 slide in the internal grooves 8, so that the first clamping blocks 6 are embedded and hermetically connected in the clamping grooves 4. At this time, pull down the sleeving ring 11 and make the second clamping blocks 7 embed in the limiting grooves 10. At this time, the internal blocks 12 on the second clamping blocks 7 are embedded in the internal grooves 8, and moreover, the external threads on the second clamping blocks 7 are engaged with the threads on the connecting pipe 3. Pull down the screwing cap 5 and screw it clockwise to fix it. The operation is simple and convenient to use.

The special components or slots in this embodiment can be obtained through market purchase or customization.

[0025] The implementation principle of an anti-blocking short oil needle in an embodiment of this application is as follows: during installation and connection, since the sleeved ring 11 is slidably connected to the needle body 2, pull up the sleeved ring 11 and the screwing cap 5, and then make the two first clamping blocks 6 respectively embed in the bottom of the limiting groove 10. At this time, the embedding tube 14 is inserted into the central cavity of the installation base 1. Subsequently, rotate the needle body 2 clockwise. During the rotation process, the first clamping block 6 slides in the limiting groove 10, and the internal block 12 slides in the internal groove 8, so that the first clamping block 6 embeds and is hermetically connected in the clamping groove 4. At this time, pull down the sleeved ring 11 and make the second clamping block 7 embed in the limiting groove 10. At this time, the internal block 12 on the second clamping block 7 is embedded in the internal groove 8, and moreover, the external thread on the second clamping block 7 fits with the thread on the connecting tube 3. Pull down the screwing cap 5 and fix it by screwing clockwise. The operation is simple and convenient to use.
