Description

Technical Field

[0001] This application relates to the field of building construction technology, and in particular to a quick-installation straight thread sleeve tightening tool and its usage method. Background Technology

[0002] In the construction process, the connection between steel bars is usually achieved by first processing the ends of the steel bars into screw heads, and then connecting the two screw heads together through a straight threaded sleeve, which is called a straight threaded connection of steel bars.

[0003] In related technologies, the tightening tools for rebar threaded sleeves are mainly pipe wrenches or wrenches. When using them, workers hold the rebar with a wrench, turn it, then remove it from the rebar and re-insert it, tightening it again, repeating this process. This repeated removal and insertion for tightening results in low installation efficiency. Summary of the Invention

[0009] Preferably, the sliding member includes an adjusting rod hinged to the operating lever and a push spring sleeved on the rack. The hinge axis of the adjusting rod is parallel to the axis of the fixed ring. One end of the adjusting rod near the fixed ring is located on the side of the rack away from the fixed ring and abuts against the side of the rack away from the fixed ring. The end of the adjusting rod near the fixed ring is used to push the rack to slide in a direction closer to the fixed ring. One end of the push spring is disposed on the fixed ring, and the other end is disposed on the side of the rack away from the fixed ring. The push spring is used to push the rack to slide in a direction away from the fixed ring.

[0010] Preferably, a positioning spring is provided between the end of the adjusting rod away from the fixed ring and the operating rod.

A placement block for placing a reinforcing bar is provided on the base. A sliding seat is slidably arranged between the placement block and the fixed platform. The sliding direction of the sliding seat is parallel to the axial direction of the straight threaded sleeve. A guide rail is provided on the sliding seat. The guide rail is arc-shaped and concentric with the straight threaded sleeve. A slider is slidably arranged on the guide rail. The slider is detachably connected to the operating rod. A fixing ring is concentric with the guide rail.

[0012] Preferably, the fixing member includes two clamping plates that are slidably disposed on the fixing platform and a second bidirectional screw that is rotatably disposed on the fixing platform. The two clamping plates are used to clamp or release the straight threaded sleeve. The rotation axis of the second bidirectional screw is parallel to the sliding direction of the clamping plates. The two clamping plates are respectively threaded to both ends of the second bidirectional screw.

[0013] Preferably, two placement blocks are symmetrically arranged along the fixed platform.

[0014] Preferably, the longitudinal section of the clamping block is arc-shaped, and the side of the clamping block near the reinforcing bar is provided with multiple anti-slip patterns.

Then, use the adjusting mechanism to move the two clamping blocks away from each other, disengaging them from the reinforcing bar. Next, move the operating rod in the opposite direction to the appropriate position, and then use the adjusting mechanism again to move the two clamping blocks closer together, clamping the reinforcing bar. Hold the operating rod and continue moving it, causing the two clamping blocks to rotate and continue connecting the reinforcing bar with the straight threaded sleeve. Repeat this process to fix the reinforcing bar with the straight threaded sleeve, eliminating the need to repeatedly remove and insert the sleeve for tightening, thus improving installation efficiency and making the operation quick and convenient.

[0029] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0030] This application discloses a quick-installation tool for tightening straight thread sleeves. (See also...) Figure 1 and Figure 2 The quick-installation straight thread sleeve tightening tool includes a base 10, a fixing ring 1, and an operating rod 2 fixedly connected to the outer wall of the fixing ring 1. A fixing platform 11 is fixedly installed in the middle of the base 10. An installation port 22 is opened on the fixing platform 11. A fixing element 12 for fixing the straight thread sleeve is installed in the installation port 22. A placement block 13 for placing steel bars is fixedly connected to the upper surface of the base 10. Two placement blocks 13 are symmetrically arranged along the fixing platform 11. The longitudinal section of the placement block 13 is a U-shaped block. The fixing platform 11 and the two placement blocks 13 are located on the same straight line.

[0031] Reference Figure 1 and Figure 2 A sliding seat 14 is slidably disposed on the base 10. The sliding seat 14 includes sliding blocks 141 slidably connected to opposite sides of the base 10. The sliding direction of the sliding blocks 141 is parallel to the arrangement direction of the placement block 13 and the fixed platform 11. The sliding seat 14 is located between the placement block 13 and the fixed platform 11. A bracket 18 is hinged to one side of the sliding block 141 of the sliding seat 14. The hinge axis of the bracket 18 is parallel to the arrangement direction of the placement block 13 and the fixed platform 11. A pin 19 is slidably disposed on the side of the bracket 18 away from the hinge axis. The sliding direction of the pin 19 is perpendicular to the hinge axis of the bracket 18. A socket (not shown in the figure) is opened on the sliding block 141 on the other side of the sliding seat 14 to engage with the pin 19. The bracket 18 and the sliding seat 14 are fixed through the engagement between the pin 19 and the socket, so that the bracket 18 is mounted on the base 10. When the pin 19 is engaged with the socket, the guide rail 15 and the straight threaded sleeve are concentric.

[0032] Reference Figure 2 and Figure 3A guide rail 15 is fixedly connected to the side of the bracket 18 away from the fixed platform 11. The longitudinal section of the guide rail 15 is arc-shaped, and the guide rail 15 has a double-rail structure. Slider blocks 16 are slidably connected to both rails of the guide rail 15. The line connecting the two sliders 16 passes through the center of the guide rail 15. The two sliders 16 are detachably connected to the operating rod 2 via a shaped plate 20. In this embodiment, the shaped plate 20 is fixed to the operating rod 2 with bolts. In other embodiments, bolts can be replaced with screws, etc. The fixing ring 1 is tangent to the operating rod 2. When the slider 16 is fixedly connected to the operating rod 2, the guide rail 15 and the fixing ring 1 are concentric, so that when the operating rod 2 moves the slider 16 on the guide rail 15, the fixing ring 1 rotates around the center. A limit block 28 is fixed to one end of the guide rail 15. When the operating rod 2 abuts against the limit block 28, the operating rod 2 is in a horizontal state, making it difficult for the operating rod 2 to fall off the guide rail 15.

[0033] Reference Figure 2 and Figure 3 The fixing ring 1 has a notch 3 on the side away from the operating rod 2 for moving the reinforcing bar in or out. When the operating rod 2 abuts against the limiting block 28, the notch 3 is oriented downwards. Two clamping blocks 4 are slidably arranged inside the fixing ring 1. The sliding direction of the clamping blocks 4 is perpendicular to the axis of the fixing ring 1 and parallel to the length direction of the operating rod 2. The longitudinal section of the clamping blocks 4 is arc-shaped, and the two clamping blocks 4 protrude outwards in a direction away from each other. The two clamping blocks 4 are used to clamp or release the reinforcing bar.

[0034] Reference Figure 3 and Figure 4 A guide rod 21 is fixed inside the fixing ring 1. The guide rod 21 is located on the side of the clamping block 4 away from the notch 3, and the length direction of the guide rod 21 is parallel to the sliding direction of the clamping block 4. A connecting block 27 is fixed on the side of the clamping block 4 near the operating rod 2. The connecting block 27 is slidably sleeved on the guide rod 21, which helps to guide the sliding of the clamping block 4. Multiple anti-slip textures 17 are provided on the sides of the clamping blocks 4 that are close to each other, which helps to enhance the fixing effect of the clamping blocks 4 on the reinforcing bars. The fixing ring 1 is provided with an adjustment mechanism for adjusting the two clamping blocks 4 to move closer or further apart.

[0035] In use, the straight threaded sleeve is fixed to the fixed platform 11 by the fastener 12. Then, the bracket 18 is rotated towards the base 10 to align the pin 19 with the insertion hole. The pin 19 is then inserted into the insertion hole to fix the bracket 18 and the sliding seat 14. At this time, the straight threaded sleeve and the guide rail 15 are concentric. Next, the rebar to be installed is placed on the placement block 13 through the fixing ring 1. The rebar is positioned between the two clamping blocks 4, aligning the rebar with the straight threaded sleeve. Then, the two clamping blocks 4 are driven closer together by the adjustment mechanism, clamping the rebar. At this time, the operating lever 2 is moved, causing the two sliders 16 to move along the guide rail 15. As the operating lever 2 moves circumferentially along the center of the fixing ring 1, the two clamping blocks 4 cause the rebar to rotate, thus rotating the rebar. The rebar is gradually connected to the threaded sleeve via a threaded connection, and the sliding seat 14 allows for lateral movement of the rebar. Then, the adjusting mechanism drives the two clamping blocks 4 away from each other, disengaging them from the rebar. Next, the operating rod 2 is moved in the opposite direction, rotating the fixing ring 1 to a suitable position. Then, the adjusting mechanism drives the two clamping blocks 4 closer together, clamping the rebar. The operating rod 2 is then held and moved further, causing the two clamping blocks 4 to rotate the rebar and continue the threaded connection with the threaded sleeve. This process is repeated to fix the rebar to the threaded sleeve, eliminating the need for repeated removal and tightening, thus improving installation efficiency. Because the tool is symmetrically arranged on both sides, it allows for simultaneous connection of rebars in both threaded sleeves, further improving installation efficiency and making it quick and convenient. Furthermore, the clamping blocks 4 are suitable for rebars of different diameters, making it widely applicable.

[0036] After the reinforcing bar and the straight threaded sleeve are installed, the straight threaded sleeve is loosened by the fixing piece 12. The adjusting mechanism drives the two clamping blocks 4 to move away from each other and disengage from the reinforcing bar. Then, the pin 19 is pulled out of the insertion hole. The operating rod 2 is moved so that the notch 3 faces downward. Then, the bracket 18 is rotated away from the base 10. The bracket 18 drives the operating rod 2 and the fixing ring 1 to rotate, so that the fixing ring 1 is removed from the reinforcing bar. At this time, the installed reinforcing bar and the straight threaded sleeve can be removed from the base 10. Since the operating rod 2 is detachably connected to the two sliders 16, it is easy to remove the operating rod 2 and the fixing ring 1 for separate use. It is highly practical and suitable for different scenarios.

[0037] Reference Figure 1 and Figure 2To facilitate fixing the straight threaded sleeve to the fixing platform 11, the fixing member 12 includes a clamping plate 121 and a second bidirectional screw 122. Two clamping plates 121 are arranged opposite each other, and the two clamping plates 121 are slidably disposed within the mounting opening 22. The sliding direction of the clamping plates 121 is perpendicular to the axial direction of the straight threaded sleeve and is horizontal. The two clamping plates 121 are used to clamp the straight threaded sleeve. The longitudinal section of the clamping plates 121 is arc-shaped, and the two clamping plates 121 protrude outwards in a direction away from each other. Friction surfaces are provided on the sides of the clamping plates 121 that are close to each other. The clamping plate 121 has a protrusion 24 fixed on the groove 23. The bottom wall of the mounting port 22 has a groove 25 that slides with the protrusion 24. The second bidirectional screw 122 is rotatably disposed in the groove 25. The rotation axis of the second bidirectional screw 122 is parallel to the sliding direction of the clamping plate 121. The two protrusions 24 are respectively threaded to the two ends of the second bidirectional screw 122. One end of the second bidirectional screw 122 is rotatably mounted on the fixed platform 11. The end of the second bidirectional screw 122 located outside the fixed platform 11 is fixedly connected to a handle 26 to facilitate the rotation of the second bidirectional screw 122.

[0038] When it is necessary to fix the straight threaded sleeve, place the straight threaded sleeve between the two clamping plates 121, hold the straight threaded sleeve with one hand, and turn the handle 26 with the other hand. The handle 26 drives the second double-direction screw 122 to rotate. The second double-direction screw 122 drives the two protrusions 24 to move the two clamping plates 121 closer together. The two clamping plates 121 clamp the straight threaded sleeve. The friction groove 23 helps to enhance the friction between the clamping plates 121 and the clamped object, so that during installation, there is no need to manually support the straight threaded sleeve, making the operation convenient and improving the installation efficiency. When it is necessary to remove the straight threaded sleeve, turn the handle 26. The handle 26 drives the second double-direction screw 122 to rotate. The second double-direction screw 122 drives the two protrusions 24 to move the two clamping plates 121 away from each other, so that the two clamping plates 121 are disengaged from the straight threaded sleeve, making it convenient to remove the straight threaded sleeve.

[0039] Reference Figure 3 and Figure 4 To facilitate adjustment of the two clamping blocks 4 towards or away from each other, the adjustment mechanism includes a first bidirectional screw 5 and a rotating assembly. The first bidirectional screw 5 is rotatably mounted inside the fixed ring 1, and its rotation axis is parallel to the sliding direction of the clamping blocks 4. The first bidirectional screw 5 is located on the side of the guide rod 21 away from the notch 3. Two connecting blocks 27 are threaded to both ends of the first bidirectional screw 5. The rotating assembly is mounted on the fixed ring 1 and is used to adjust the rotation of the first bidirectional screw 5. Adjusting the rotation of the first bidirectional screw 5 by the rotating assembly helps the first bidirectional screw 5 drive the two connecting blocks 27 to move the two clamping blocks 4 closer or further apart, which helps to clamp the reinforcing bars and facilitates the rotation of the reinforcing bars to connect with the straight threaded sleeve.

[0040] Reference Figure 3 and Figure 4 To facilitate adjustment of the rotation of the first bidirectional screw 5, the rotating assembly includes a gear 6, a rack 7, and a sliding member 8. The gear 6 is fixedly sleeved on the first bidirectional screw 5 and is located between the two connecting blocks 27. The rack 7 slides through the fixed ring 1, located on the side of the fixed ring 1 away from the notch 3. The sliding direction of the rack 7 is perpendicular to the sliding direction of the clamping block 4 and perpendicular to the length direction of the operating rod 2. The rack 7 meshes with the gear 6. The sliding member 8 is set on the operating rod 2 and is used to adjust the sliding of the rack 7. When the rack 7 slides towards the fixed ring 1, the rack 7 drives the gear 6 and the first bidirectional screw 5 to rotate, causing the two connecting blocks 27 and the clamping block 4 to move closer to each other. By adjusting the sliding of the rack 7 through the sliding member 8, the rack 7 drives the gear 6 and the first bidirectional screw 5 to rotate during the sliding process, thereby helping to drive the two connecting blocks 27 to move the two clamping blocks 4 closer or further apart, which helps to clamp the reinforcing bar and facilitates the rotation of the reinforcing bar and connection with the straight threaded sleeve.

[0041] Reference Figure 3 and Figure 4 To facilitate the adjustment of the rack 7's sliding, the sliding component 8 includes an adjusting rod 81 and a pushing spring 82. The adjusting rod 81 is hinged to the side of the operating rod 2 away from the guide rail 15. The hinge axis of the adjusting rod 81 is parallel to the axis of the fixed ring 1. The end of the adjusting rod 81 near the fixed ring 1 is located on the side of the rack 7 away from the fixed ring 1 and abuts against the side of the rack 7 away from the fixed ring 1. The distance from the end of the adjusting rod 81 near the fixed ring 1 to the hinge point is less than the distance from the end of the adjusting rod 81 away from the fixed ring 1 to the hinge point, making the operation more effortless. The end of the adjusting rod 81 near the fixed ring 1 is used to push the rack 7 to slide towards the fixed ring 1. The pushing spring 82 is sleeved on the end of the rack 7 located outside the fixed ring 1. One end of the pushing spring 82 is fixedly connected to the outer wall of the fixed ring 1, and the other end is fixedly connected to the side of the rack 7 away from the fixed ring 1. The pushing spring 82 is used to push the rack 7 to slide towards the direction away from the fixed ring 1. The pushing force of the pushing spring 82 is greater than the frictional force of the rotation of the first bidirectional screw 5. A positioning spring 9 is fixed between the end of the adjusting rod 81 away from the fixed ring 1 and the end of the operating rod 2 away from the fixed ring 1. The extension direction of the positioning spring 9 is perpendicular to the length direction of the operating rod 2. The positioning spring 9 helps to reset the position of the adjusting rod 81, making it less likely for the adjusting rod 81 to rotate unnecessarily.

[0042] When it is necessary to rotate the rebar, hold the end of the operating lever 2 and the adjusting lever 81 away from the fixed ring 1, and rotate the end of the adjusting lever 81 away from the fixed ring 1 toward the operating lever 2. At this time, the end of the adjusting lever 81 near the fixed ring 1 moves closer to the fixed ring 1. The adjusting lever 81 presses the rack 7, causing the rack 7 to move toward the fixed ring 1. Then, the rack 7 drives the gear 6 and the first double-acting screw 5 to rotate. At this time, the first double-acting screw 5 drives the two connecting blocks 27 to move the two clamping blocks 4 closer to each other, which helps to clamp the rebar to be installed. Then move the operating lever 2, and the operating lever 2 drives the two sliders 16 to slide on the guide rail 15. Rod 2 moves circumferentially along the center of the fixed ring 1, causing the two clamping blocks 4 to rotate the reinforcing bar and connect it to the straight threaded sleeve. After the reinforcing bar rotates to a certain angle, the adjusting rod 81 is released, and the adjusting rod 81 is reset under the action of the positioning spring 9. At the same time, the rack 7 slides away from the fixed ring 1 under the action of the pushing spring 82, causing the gear 6 and the first bidirectional screw 5 to rotate in opposite directions, driving the two connecting blocks 27 to move the two clamping blocks 4 away from each other, and the clamping blocks 4 disengage from the reinforcing bar. Then, the operating rod 2 is reversed to the appropriate position, and the operating rod 2 and the adjusting rod 81 are held again to drive the reinforcing bar to rotate. This process is repeated to facilitate the connection between the reinforcing bar and the straight threaded sleeve.

[0043] The implementation principle of this application embodiment is as follows: When in use, the straight threaded sleeve is placed between the two clamping plates 121 of the fixed platform 11. Then, the handle 26 is rotated, and the handle 26 drives the second bidirectional screw 122 to rotate. The second bidirectional screw 122 drives the two protrusions 24 to bring the two clamping plates 121 closer to each other. The two clamping plates 121 clamp the straight threaded sleeve. Then, the bracket 18 is rotated towards the direction close to the base 10 so that the pin 19 is aligned with the insertion hole. The pin 19 is inserted into the insertion hole to achieve relative fixation between the bracket 18 and the sliding seat 14. Then, the steel bar to be installed is placed in the placement block 13 on the corresponding side, and the steel bar passes through the two clamping blocks 4 of the fixed ring 1 and is aligned with the straight threaded sleeve. At this time, the operating rod 2 abuts against the limiting block 28.

[0044] Then move the operating lever 2 upward to a suitable angle. Next, hold the end of the operating lever 2 and the adjusting lever 81 away from the fixed ring 1, and rotate the end of the adjusting lever 81 away from the fixed ring 1 toward the direction closer to the operating lever 2. At this time, the end of the adjusting lever 81 close to the fixed ring 1 presses the rack 7 toward the fixed ring 1, causing the rack 7 to move toward the direction closer to the fixed ring 1. Then, the rack 7 drives the gear 6 and the first bidirectional screw 5 to rotate. At this time, the first bidirectional screw 5 drives the two connecting blocks 27 to drive the two clamping blocks 4 to move closer to each other. The two clamping blocks 4 clamp the steel bar to be installed. Then, move the operating lever 2 toward the direction closer to the limiting block 28. The operating lever 2 drives the two sliders 16 to slide on the guide rail 15. The operating lever 2 moves circumferentially along the center of the fixed ring 1, causing the two clamping blocks 4 to drive the steel bar to rotate. At this time, the steel bar is gradually connected to the straight thread sleeve.

[0045] When the operating lever 2 moves close to the limit block 28, the adjusting lever 81 is released. The adjusting lever 81 returns to its original position under the action of the positioning spring 9. At the same time, the rack 7 slides away from the fixed ring 1 under the action of the pushing spring 82, causing the gear 6 and the first bidirectional screw 5 to rotate. This drives the two connecting blocks 27 to move the two clamping blocks 4 away from each other, and the clamping blocks 4 disengage from the steel bar. Then, the operating lever 2 is reversed to the appropriate position, and the adjusting lever 81 and the operating lever 2 are gripped again so that the two clamping blocks 4 clamp the corresponding parts of the steel bar. By moving the operating lever 2, the steel bar is rotated, so that the steel bar continues to be connected to the straight thread sleeve. This process is repeated until the steel bar is completely connected to the straight thread sleeve, thus eliminating the need to repeatedly remove and insert the steel bar for tightening. This helps to improve installation efficiency and makes the operation quick and labor-saving.

[0046] After the reinforcing bar and the straight threaded sleeve are installed, loosen the adjusting rod 81 to disengage the two clamping blocks 4 from the reinforcing bar. Then move the operating rod 2 so that the notch 3 of the fixing ring 1 faces downward. Then turn the handle 26. The handle 26 drives the second bidirectional screw 122 to rotate, causing the two protrusions 24 to move the two clamping plates 121 away from each other and disengage from the straight threaded sleeve. Then pull the pin 19 out of the insertion hole and rotate the bracket 18 in a direction away from the base 10. The bracket 18 drives the operating rod 2 and the fixing ring 1 to rotate, so that the fixing ring 1 is removed from the reinforcing bar. At this time, the installed reinforcing bar and the straight threaded sleeve can be removed from the base 10.

[0047] This application also discloses a method for using a quick-installation straight thread sleeve tightening tool. The method for using the above-mentioned quick-installation straight thread sleeve tightening tool includes the following steps:

[0048] Step 1: Place the straight threaded sleeve to be installed between the two clamping plates 121 of the fixed platform 11, turn the handle 26 to make the second bidirectional screw 122 rotate and drive the two clamping plates 121 to move closer to each other, and the two clamping plates 121 clamp and fix the straight threaded sleeve to be installed.

[0049] Step 2: Rotate the bracket 18 toward the direction closer to the base 10 so that the pin 19 on the bracket 18 is engaged with the insertion hole. Place the steel bar to be connected on the placement block 13, and align the steel bar between the two clamping blocks 4 of the fixing ring 1 with the straight thread sleeve.

[0050] Step 3: Hold the end of the operating rod 2 and the adjusting rod 81 away from the fixed ring 1, and rotate the end of the adjusting rod 81 away from the fixed ring 1 toward the direction closer to the operating rod 2. The end of the adjusting rod 81 close to the fixed ring 1 presses the rack 7 and moves toward the direction closer to the fixed ring 1. The rack 7 drives the gear 6 and the first bidirectional screw 5 to rotate, driving the two clamping blocks 4 to move closer to each other, so that the two clamping blocks 4 clamp the steel bar. Then hold the operating rod 2 and the adjusting rod 81 and move them to drive the steel bar to rotate, so as to connect the end of the steel bar to the straight thread sleeve.

[0051] Step 4: After rotating a certain angle, release the adjusting rod 81. The positioning spring 9 drives the adjusting rod 81 to reset. The spring 82 pushes the rack 7 to move away from the fixed ring 1, so that the gear 6 and the first bidirectional screw 5 rotate to drive the two clamping blocks 4 away from each other, so that the two clamping blocks 4 are separated from the steel bar. Then move the operating rod 2 in the opposite direction to the appropriate position.

[0052] Step 5: Repeat steps 3-4 until the rebar and the straight threaded sleeve are connected and fixed. Turn the handle 26 to move the two clamping plates 121 away from each other. Then release the adjusting rod 81 to move the two clamping blocks 4 away from each other. Next, move the operating rod 2 to make the notch 3 face downward. Then pull out the pin 19 and turn the bracket 18 away from the base 10 to remove the connected rebar and straight threaded sleeve. Alternatively, move the rebar and straight threaded sleeve horizontally to remove them.

[0053] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application.
