[0031] The following further elaborates on this application Figures 1-3 in conjunction with the accompanying drawings.
[0032] An embodiment of this application discloses a steel bar connecting sleeve.
[0033] Referring to Figures 1-3 , a steel bar connecting sleeve includes Sleeve 1, Sleeve 2 is installed inside Sleeve 1, Steel bar 1 is installed at one end of Sleeve 1, Steel bar 2 is installed at one end of Sleeve 2, a sliding plate 5 is slidably arranged on Sleeve 1, connectors 6 are fixedly connected to one ends of Steel bar 1 and Steel bar 2 respectively, the connector 6 on one side of Steel bar 1 is threadedly connected to Sleeve 1, the connector 6 on one side of Steel bar 2 is threadedly connected to Sleeve 2, and an anti-slip pattern 15 is arranged on the outer wall of the sliding plate 5.
[0034] When using the device, first take out Sleeve 1, rotate the connector 6 on one side of Steel bar 1 into Sleeve 1, then take out Sleeve 2, rotate the connector 6 on one side of Steel bar 2 into Sleeve 2, thereby fixing Steel bar 1 to Sleeve 1 and Steel bar 2 to Sleeve 2. After the fixing is completed, insert Sleeve 2 into Sleeve 1, and through the operation of the sliding plate 5, fix Sleeve 1 and Sleeve 2, thereby connecting Steel bar 1 and Steel bar 2 to each other. Without using tools such as bolts, the two steel bars can be quickly connected and fixed, making the operation simple and convenient, reducing the construction difficulty of the operators, greatly improving the construction efficiency, accelerating the construction progress, and having a very stable connection and reliable quality.
[0035] Referring to Figures 1-3A limiting groove 7 is provided on the sleeve 1, and a spring 8 is fixedly connected in the limiting groove 7. A plurality of circular grooves are provided through the sleeve 1, and a plurality of balls 9 are arranged in the plurality of circular grooves. The diameter of the plurality of balls 9 is larger than the diameter of the circular groove. The plurality of balls 9 are located in the limiting groove 7. The sleeve 2 is slidably connected inside the sleeve 1, and a plurality of arc grooves 10 are provided on the sleeve 2. The shape and size of the plurality of arc grooves 10 are consistent with those of the balls 9. A limiting block 11 is fixedly connected inside the sliding plate 5, and the limiting block 11 is located inside the limiting groove 7. One end of the spring 8 is fixedly connected to one side of the limiting block 11, and one side of the limiting block 11 is arc-shaped.
[0036] When using the device, first rotate the connector 6 on one side of the steel bar 3 into the inside of the sleeve 1, and then rotate the connector 6 on the side of the steel bar 2 4 into the inside of the sleeve 2 2. After the fixation is completed, pull the sliding plate 5 to drive the limit block 11 to move in the limit groove 7. While the limit block 11 moves, the spring 8 is squeezed to shrink, and then the sleeve 2 2 is inserted into the sleeve 1. When the sleeve 2 2 continues to enter the sleeve 1, the outer wall of the sleeve 2 2 fits tightly with the inner wall of the sleeve 1, thereby squeezing the ball 9 on the sleeve 1 to move toward the limit groove 7. Because the diameter of the ball 9 is larger than the diameter of the circular groove, the ball 9 will not leave the circular groove. When the arc groove on the sleeve 2 When 10 reaches below the ball 9, the ball 9 loses pressure and falls into the arc groove 10, so that the sleeve 2 is limited by the cooperation of the ball 9 and the arc groove 10, and the sleeve 2 is fixed inside the sleeve 1, and then the sliding plate 5 is released, and according to the rebound of the spring 8, the limit block 11 is driven to move inside the limit groove 7 until it moves to the top of the ball 9, and the top of the ball 9 is limited and intercepted by the cover of the limit block 11 to prevent the ball 9 from separating from the sleeve 1, so that the connection between the sleeve 1 and the sleeve 2 is more stable, and the two steel bars can be quickly connected and fixed without using tools such as bolts through the cooperation of the ball 9 and the arc groove 10;
[0037] Secondly, when disassembly and replacement are required, it is only necessary to pull the sliding plate 5 again to squeeze the spring 8 to release the limit block 11 on the top of the ball 9. At this time, one end of the steel bar 2 4 can be pulled to separate the ball 9 and the arc groove 10, so that the sleeve 2 2 is pulled out from the inside of the sleeve 1, and the steel bar 1 3 and the steel bar 2 4 can be separated more quickly and conveniently.
[0038] Reference Figures 1-3 A fixing plate 12 is fixedly connected inside the sleeve 1, and a slot 13 is opened on one side of the fixing plate 12. The connecting head 6 on one side of the steel bar 13 is fitted with one side of the fixing plate 12. A clamping block 14 is fixedly connected to one end of the sleeve 22, and one end of the sleeve 22 is fitted with one side of the fixing plate 12. The clamping block 14 is located inside the slot 13.
[0039] When installing, first rotate the connector 6 on one side of the steel bar 3 into the inner part of the sleeve 1, so that one end of the connector 6 is closely attached to one side of the fixing plate 12. Then rotate the connector 6 on one side of the steel bar 4 into the inner part of the sleeve 2. Subsequently, insert the sleeve 2 into the inner part of the sleeve 1, so that the clamping block 14 at one end of the sleeve 2 enters the inner part of the clamping groove 13. Through the cooperation of the clamping groove 13 and the clamping block 14, the sleeve 2 is fixed more stably in the sleeve 1, avoiding shaking during use. At the same time, by closely attaching the two connectors 6 to both sides of the fixing plate 12, the insertion depth of the two connectors 6 can be ensured, greatly improving the connection efficiency of the steel bars and enhancing safety.
[0040] The implementation principle of a steel bar connecting sleeve in this embodiment is as follows: When using the device, first take out the sleeve 1 and rotate the connector 6 on one side of the steel bar 3 into the inner part of the sleeve 1, so that one end of the connector 6 is closely attached to one side of the fixing plate 12. Then take out the sleeve 2 and rotate the connector 6 on one side of the steel bar 4 into the inner part of the sleeve 2, thereby fixing the steel bar 3 to the sleeve 1 and the steel bar 4 to the sleeve 2. After the fixing is completed, pull the sliding plate 5 to drive the limiting block 11 to move inside the limiting groove 7. While the limiting block 11 is moving, the spring 8 is compressed and contracted. Subsequently, insert the sleeve 2 into the inner part of the sleeve 1, so that the clamping block 14 at one end of the sleeve 2 enters the inner part of the clamping groove 13. Through the cooperation of the clamping groove 13 and the clamping block 14, the sleeve 2 is fixed more stably in the sleeve 1, avoiding shaking during use. At the same time, by closely attaching the two connectors 6 to both sides of the fixing plate 12, the insertion depth of the two connectors 6 can be ensured, greatly improving the connection efficiency of the steel bars and enhancing safety;
[0041] Secondly, when the sleeve 2 continues to enter the inner part of the sleeve 1, the outer wall of the sleeve 2 is closely attached to the inner wall of the sleeve 1, thereby squeezing the ball 9 on the sleeve 1 to move towards the limiting groove 7. When the arc-shaped groove 10 on the sleeve 2 reaches below the ball 9, the ball 9 loses pressure and falls into the arc-shaped groove 10. Through the cooperation of the ball 9 and the arc-shaped groove 10, the sleeve 2 is limited, and the sleeve 2 is fixed in the sleeve 1. Then release the sliding plate 5. According to the rebound of the spring 8, drive the limiting block 11 to move inside the limiting groove 7 until it moves to the top of the ball 9. The top of the ball 9 is limited and intercepted by the covering of the limiting block 11, avoiding the separation of the ball 9 from the sleeve 1, making the connection between the sleeve 1 and the sleeve 2 more stable. Through the cooperation of the ball 9 and the arc-shaped groove 10, the two steel bars can be quickly connected and fixed without using tools such as bolts, making the operation simple and convenient, reducing the construction difficulty of the operators, greatly improving the construction efficiency, accelerating the construction progress, and the connection is very firm and the quality is stable and reliable;
[0042] In addition, when disassembly and replacement are required, simply pull the sliding plate 5 again to squeeze the spring 8, and the limit on the top of the ball 9 by the limit block 11 can be released. At this time, one end of the second steel bar 4 can be pulled to separate the ball 9 from the arc groove 10, so that the second sleeve 2 can be withdrawn from the first sleeve 1, and the first steel bar 3 and the second steel bar 4 can be separated more quickly and conveniently.
