Specific embodiment

With reference to Fig. 1, Fig. 2, a kind of Pneumatic elevation tap, including tap 1, tap 1 time is equipped with movable mandrel 21, work Moving mandrel 21 is inserted in positioning shell 24, movable mandrel 21 can by under the drive of tap 1 in shell 24 is positioned up and down It is mobile；Movable 21 lateral wall of mandrel is equipped with upper sealing ring block 23, and movable 21 lower end outside wall of mandrel is equipped with locating part 27；It is positioning 24 lower end inner wall of shell is equipped with lower seal block 26, and locating part 27 is located at 26 lower section of lower seal block, to avoid when in use Movable mandrel 21 is extracted out from positioning shell 24；It is outer in upper sealing ring block 23, lower seal block 26, movable mandrel 21, positioning Airtight cavity 29 is formed between shell 24, positioning 24 side wall of shell is provided with the venthole 30 connected with airtight cavity 29, makes air can be into Enter in airtight cavity 29, for that can regulate and control to the disengaging of air, check valve 28 is housed on venthole；When upper water lift tap 1 When drive activity mandrel 21 is upward, outside air can be entered by check valve 28 in airtight cavity 29, and ensure that air will not be outer Let out, to ensure that tap 1 is highly fixed, and 1 angle of tap is rotatable, make angle of water can according to needs when using come Adjustment；When need to highly decline tap 1, check valve 28 can be opened by the other manners such as pressing, rotating, make airtight cavity Air in 29 is discharged by check valve 28, so that movable mandrel 21 declines.

To further improve movable mandrel 21 and positioning the working effect that cooperates between shell 24, by movable mandrel 21 from Linkage section 211, closed section 212, the /V section 213 that outer diameter successively decreases are divided under；The outer diameter of linkage section 211 is smaller In positioning 24 internal diameter size of shell, make positioning shell 24 closed in the opposite formation in top, before tap 1 is not promoted, closed chamber Body 29 is located between closed section 212 and positioning shell 24, and after tap 1 is promoted, the airtight cavity 29 is located at by closed section 212nd, enclosed between /V section 213 and positioning 24 three of shell in space；Linkage section 211 is equipped with and coordinates with tap 1 simultaneously External screw thread 201, be threadedly coupled with tap 1；Because linkage section 211 during movable mandrel 21 moves up and down with position shell It rubs between 24 inner walls, to avoid the abrasion of positioning shell 24 inner wall, 211 outer wall of linkage section, is set in positioning 24 upper end inner wall of shell There is wear-resisting ring 22；Sealing ring block 23 is arranged on closed section 212, further to increase the seal of airtight cavity 29, avoids air It is excessive from this, it is not fixed 1 height of tap, meeting automatic descending, to improve the leakproofness of upper sealing ring block 23, using " V " shape Sealing ring；Locating part 27 is arranged on 213 lower end of /V section, other elastic materials such as washer can be used.

Because deflated by check valve 28 tap 1 is declined when, because tap 1 is conducted oneself with dignity larger, closed section of 212 meetings can be made It collides between lower seal block 26, generates abnormal sound, easily causing lower seal block 26 after long-time deforms upon, and influences closed Cavity 29 it is closed, therefore buffer gravity when tap 1 declines by being equipped with cushion pad 25 at the top of lower seal block 26, Mitigate the impact to locating part 29, and improve abnormal sound, and the leakproofness to improve sealing ring block 26, it sets on sealing ring block 26 Fluted 202, " O " shape sealing ring 203 is housed in groove 202.

With reference to Fig. 2, Fig. 3, Fig. 4, the work of check valve 28 is expanded on further, check valve 28 is included in insertion venthole 30 Button spindle 281, the spring 284 being placed on button spindle 281, button spindle 281 are fixed on by clamping nut 283 outside positioning shell 24 It is equipped on wall, on button spindle 281 positioned at clamping nut 283 and positions the sealing ring 282 between shell 24；It is highly needed in tap 1 When rising, by lifting tap 1 upwards, make button spindle 281, sealing ring 282 and spring 284 together to 29 side of airtight cavity To movement；Between button spindle 281 and clamping nut 283, between sealing ring 282 and clamping nut 283, sealing ring 282 with it is fixed Position shell 24 on 30 inner wall of venthole between, spring 284 and positioning shell 24 on 30 inner wall of venthole between, button spindle 281 and positioning shell 24 on 30 inner wall of venthole between form gap so that external air through gap through venthole 30 into Enter into airtight cavity 29, make tap 1 highly fixed.

In 1 highly desirable decline of tap, by pressing or rotating button spindle 281, make button spindle 281, sealing ring 282 With spring 284 continue to 29 direction of airtight cavity move, between button spindle 281 and clamping nut 283, sealing ring 282 with pressure Between 30 inner wall of venthole between tight nut 283, on sealing ring 282 and positioning shell 24, on spring 284 and positioning shell 24 30 inner wall of venthole between, button spindle 281 and positioning shell 24 on 30 inner wall of venthole between form gap, make air from Airtight cavity 29 is discharged to the outside through venthole 30, gap, and after tap 1 is completed to decline, spring 284 is sprung back button spindle 281 reset.

During use is put into practice, this tap 1 has using simple, 1 height fixing-stable of tap, adjustable angle The advantages of.

According to above-mentioned principle, the utility model can also carry out the above embodiment appropriate change and modification.Therefore, The utility model is not limited to specific embodiment disclosed and described above, to some modifications and changes of the utility model It should also be as falling into the scope of the claims of the utility model.
