[0016] Compared with the prior art, the beneficial effect of the present invention is that when the cylinder anti-loosening locking ring with a self-locking structure is in use, the cylinder assembly to be locked can be inserted into the positioning ring, and the clamping block is squeezed by the cylinder assembly, and the clamping block will cooperate with the sleeve and the telescopic rod to shrink, and at the same time, the movable spring is squeezed by the telescopic block. When the cylinder assembly is completely docked in the positioning ring, the clamping block will be reset by the movable spring, so that the clamping block can clamp the cylinder assembly in the positioning ring, and thus has the effect of self-locking the cylinder assembly. This is the use feature of the cylinder anti-loosening locking ring with a self-locking structure.

[0017] 1. The cylinder anti-loosening locking ring with a self-locking structure can be inserted into the middle of the positioning ring when the cylinder assembly needs to be self-locked. When the cylinder assembly is inserted, the clamping block is squeezed by the cylinder assembly, which will drive the sleeve and the telescopic block to shrink inside the fixed ring and squeeze the movable spring in the groove of the positioning ring.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] See also Figure 1 , Figure 2 and Figure 4 The present invention provides a technical solution: a cylinder anti-loosening locking ring with a self-locking structure, comprising a mounting seat 1 and a clamping block 5, a positioning ring 2 is installed on the top of the mounting seat 1 through a slide groove, a sleeve 3 is connected to the inside of the positioning ring 2, a telescopic rod 4 is connected to the middle of the sleeve 3, and the clamping block 5 is installed on one side of the telescopic rod 4;

[0032] A fixing ring 6 is installed on the outer side of the positioning ring 2, a wedge block 7 is installed on one side of the sleeve 3, a roller 8 is arranged on the inner side of the wedge block 7, a connecting ring 9 is connected to one side of the roller 8, a pull rod 10 passing through the fixing ring 6 is connected to one side of the connecting ring 9, telescopic blocks 11 are installed on both sides of the sleeve 3 through protrusions, a movable spring 12 is connected between the telescopic block 11 and the groove of the positioning ring 2, and the connecting ring 9 is sleeved on the outer side of the positioning ring 2.

[0033] When the cylinder assembly needs to be self-locked, the cylinder assembly to be fixed can be inserted into the positioning ring 2. During the process of inserting the cylinder assembly, the cylinder assembly squeezes the inclined surface of the clamping block 5. Since the telescopic rod 4 is connected to the sleeve 3 through the rack 13 and the tooth block 21, when the clamping block 5 is squeezed by the cylinder assembly, the sleeve 3 will be driven to shrink into the groove of the fixing ring 6, and the telescopic blocks 11 on both sides of the sleeve 3 will squeeze the movable spring 12 in the groove of the positioning ring 2. When the cylinder assembly is completely installed in the positioning ring 2, the clamping block 5 is not squeezed by the cylinder assembly, and the sleeve 3 will be reset through the movable spring 12 and the telescopic block 11, and the clamping block 5 is driven to dock into the groove of the cylinder assembly through the telescopic rod 4 at one end of the sleeve 3. When it is blocked by the clamping block 5, the cylinder assembly can be self-locked in the positioning ring 2, thereby having a self-locking effect.

[0034] On the contrary, the pull rod 10 on one side of the fixed ring 6 can be rotated. Since the pull rod 10 passes through the fixed ring 6 and is connected to one side of the connecting ring 9, the pull rod 10 will drive the connecting ring 9 to rotate. A roller 8 is connected to one side of the connecting ring 9. When the connecting ring 9 rotates, it will drive the roller 8 to rotate. A wedge block 7 is provided on one side of the roller 8, and the wedge block 7 is installed on one side of the sleeve 3. When the roller 8 rotates, it will squeeze the wedge block 7 on one side, so that the wedge block 7 drives the sleeve 3 to shrink toward the inside of the fixed ring 6 again. When the sleeve drives the clamping block 5 to shrink toward the inside of the fixed ring 6 through the telescopic rod 4, the clamping block 5 does not limit the clamping of the cylinder assembly, so that the cylinder assembly can be quickly separated from the positioning ring 2.

[0035] See also Figure 2 , Figure 4 , Figure 8 and Fig. 9 It can be seen that during use, the cylinder assembly can be inserted into the middle of the positioning ring 2 according to the requirements of use. When the cylinder assembly is inserted, the cylinder assembly will squeeze the clamp block 5, and the clamp block 5 will be squeezed and contracted toward the inside of the fixing ring 6 through the sleeve 3. When the cylinder assembly is completely docked with the positioning ring 2, the clamp block 5 will drive the sleeve 3 and the clamp block 5 to reset through the reset action of the movable spring 12, so that the cylinder assembly can be self-locked in the positioning ring 2.

[0036] A rack 13 is installed on one side of the telescopic rod 4, and a connecting gear 14 is meshedly connected to one side of the rack 13. An inner gear ring 15 is installed on the outer side of the connecting gear 14, and the inner gear ring 15 is slidably connected to the inner wall of the fixed ring 6. A rotating shaft 16 that passes through the fixed ring 6 is connected in the middle of the connecting gear 14, and a connecting block 17 is connected to one end of the rotating shaft 16. A first screw 18 is penetrated and connected to one side of the connecting block 17, and one end of the first screw 18 is inserted into a circular groove 19 on one side of the fixed ring 6. A clamping block 20 is installed inside the circular groove 19. A tooth block 21 is set on one side of the rack 13, and a second screw 22 that passes through the sleeve 3 and the fixed ring 6 is connected to one side of the tooth block 21 through a bearing. The connecting gear 14 is symmetrically installed in three groups about the center line of the positioning ring 2.

[0037] In specific implementation, the cylinder anti-loosening locking ring with a self-locking structure only needs to rotate the second screw 22 when the self-locking position of the clamping block 5 needs to be adjusted. Since the second screw 22 is connected to the tooth block 21 through a bearing, and the second screw 22 is threadedly connected to the sleeve 3, and the tooth block 21 can only be extended and retracted along the groove of the sleeve 3, the second screw 22 can be rotated to make the second screw 22 drive the tooth block 21 to move, and the tooth block 21 is separated from the rack 13 on one side of the telescopic rod 4. At this time, the telescopic rod 4 can drive the clamping block 5 to freely extend and retract along the sleeve 3;

[0038] At the same time, the first screw 18 is rotated. Since the screw and the connecting block 17 are threadedly connected, rotating the first screw 18 will drive the connecting block 17 to move, and the first screw 18 will be separated from the block 20 in the circular groove 19 on the side of the fixing ring 6. Without the first screw 18 limiting the rotating shaft 16 through the connecting block 17, the rotating shaft 16 can be rotated, so that the rotating shaft 16 drives the connecting gear 14 to rotate. Since half of the connecting gear 14 is meshed with the rack 13 and the other half is meshed with the inner gear ring 15, and the inner gear ring 15 is slidably connected to the inside of the fixing ring 6, when the connecting gear 14 rotates, it will drive the inner gear ring 15 to rotate. The gear ring 15 rotates, and the inner gear ring 15 meshes with the other two groups of connecting gears 14, and the other two groups of connecting gears 14 are respectively connected to the corresponding racks 13, so the connecting gear 14 will drive the rack 13 to move when it rotates, and the rack 13 is installed on one side of the telescopic rod 4. At this time, the rack 13 will make the telescopic rod 4 move along the sleeve 3, and cooperate with the connecting gear 14 and the rack 13 to make the telescopic rod 4 drive the three groups of clamping blocks 5 to move closer to each other or move away from each other. By adjusting the positions of the three groups of clamping blocks 5, cylinder assemblies of different sizes can be locked, thereby meeting the different usage requirements of users;

[0039] After the position of the clamping block 5 is adjusted, the second screw 22 is rotated in the opposite direction so that the second screw 22 drives the tooth block 21 to dock with the rack 13 on one side of the telescopic rod 4. At this time, the telescopic rod 4 and the sleeve 3 are an integral whole with each other, so as not to affect the normal use of the clamping block 5. Then, the first screw 18 is rotated in the opposite direction so that the first screw 18 docks with the circular groove 19 on the side of the fixing ring 6 and docks with the block 20 in the circular groove 19. At this time, the position of the rotating shaft 16 can be fixed, so that the rotating shaft 16 is not easily rotated at will.

[0040] See also Figure 2-Figure 5 and Figure 7-Figure 9 It can be seen that when in use, the second screw 22 and the first screw 18 can be rotated in sequence according to the size of the cylinder assembly. At this time, the rotating shaft 16 can drive the connecting gear 14 to rotate. When the connecting gear 14 rotates, it will drive the clamping block 5 to move through the rack 13 and the telescopic rod 4. By adjusting the position of the clamping block 5, the cylinder assemblies of different sizes can be limited and locked, thereby meeting the different usage requirements of users.

[0041] A transmission shaft 23 is connected through the top of the mounting seat 1, and a first bevel gear 24 is connected to the bottom of the transmission shaft 23. The bottom of the first bevel gear 24 is meshed with a second bevel gear 25. A bidirectional screw rod 26 is connected through the middle of the second bevel gear 25. A screw sleeve 27 is sleeved on the outer side of the bidirectional screw rod 26. The top of the screw sleeve 27 is connected to a connecting rod 28 through a rotating shaft. The top of the connecting rod 28 is connected to a rotating block 29 through a rotating shaft. One end of the rotating block 29 is connected to the groove of the mounting seat 1 through a rotating shaft. A pressure block 30 is installed on one side of the rotating block 29. A retaining ring 31 is provided at the bottom of the pressure block 30. The retaining ring 31 is installed on both sides of the fixing ring 6. Two groups of rotating blocks 29 are installed symmetrically about the center line of the bidirectional screw rod 26.

[0042] In specific implementation, the cylinder anti-loosening locking ring with a self-locking structure can rotate the transmission shaft 23 when the angle of the entire positioning ring 2 needs to be adjusted. Since the bottom of the transmission shaft 23 is connected to the first bevel gear 24, and the first bevel gear 24 and the second bevel gear 25 are meshed with each other, and the middle of the second bevel gear 25 is connected with a bidirectional screw rod 26, when the transmission shaft 23 rotates, the bidirectional screw rod 26 will be driven to rotate through the first bevel gear 24 and the second bevel gear 25. Two sets of screw sleeves 27 are respectively sleeved at both ends of the bidirectional screw rod 26, and the tops of the two sets of screw sleeves 27 are connected to the connecting rod 28 through the rotating shaft, and the connecting rod 28 The other end is connected to the bottom of the rotating block 29 through a rotating shaft. When the two-way screw rod 26 drives the two sets of screw sleeves 27 to slide away from each other, the connecting rod 28 will rotate, and the connecting rod 28 will drive the rotating block 29 to rotate upward through the rotating shaft between the groove of the mounting seat 1. When the rotating block 29 rotates, it will simultaneously drive the pressure block 30 on one side to rotate upward. At this time, the pressure block 30 does not squeeze the snap ring 31 on the outside of the fixing ring 6. Then the positioning ring 2 can be rotated, so that the positioning ring 2 can slide along the slide groove of the mounting seat 1 through the outer fixing ring 6 and the snap ring 31, so as to facilitate the adjustment of the locking position of the clamping block 5 on the cylinder assembly;

[0043] When the angle of the positioning ring 2 is adjusted, the transmission shaft 23 is rotated in the opposite direction, and the bidirectional screw rod 26 is driven to rotate in the opposite direction through the first bevel gear 24 and the second bevel gear 25. When the bidirectional screw rod 26 rotates in the opposite direction, the screw sleeve 27 drives the rotating block 29 to rotate in the opposite direction through the connecting rod 28. At this time, the pressing block 30 will squeeze the retaining ring 31. The retaining ring 31 is squeezed by the pressing block 30 and cannot drive the positioning ring 2 to slide along the mounting seat 1, so that the position of the positioning ring 2 can be fixed.

[0044] See also Figure 2 and Figure 6It can be seen that when in use, the transmission shaft 23 can be rotated according to the limit position of the clamp block 5, and the transmission shaft 23 will drive the bidirectional screw 26 to rotate through the first bevel gear 24 and the second bevel gear 25, and at the same time cooperate with the screw sleeve 27 and the connecting rod 28 to drive the rotating block 29 and the pressing block 30 to rotate upward. At this time, the pressing block 30 does not squeeze the retaining ring 31, so that the positioning ring 2 can rotate along the mounting seat 1, which is convenient for adjusting the limit locking position of the clamp block 5 on the cylinder assembly.

[0045] To sum up, when the cylinder anti-loosening locking ring with a self-locking structure is in use, the mounting base 1 can be placed in a stable position, and then the cylinder assembly to be locked can be inserted into the positioning ring 2, and the clamping block 5 can be squeezed by the cylinder assembly so that the clamping block 5 can be extended and retracted through the sleeve 3. When the cylinder assembly is completely docked in the positioning ring 2, the movable spring 12 will cooperate with the clamping block 5 to stably limit the cylinder assembly in the positioning ring 2, thereby preventing the cylinder assembly from loosening during use. This is the use feature of the cylinder anti-loosening locking ring with a self-locking structure. The content not described in detail in this description belongs to the existing technology known to professional and technical personnel in this field.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
