DETAILED DESCRIPTION
[0025] The present invention is further described below through specific implementation methods.
[0026] like Figures 1 to 4 As shown, the adjustable tensioner described in the utility model comprises a supporting member 1, a sleeve 2 and a fixing rod 3.
[0027] The abutment member 1 includes an operating abutment section 11 and a first threaded connection section 12, the sleeve 2 includes a second threaded connection section 21 and a rotation connection section 22, the fixing rod 3 is used to be connected to the cable 5 and is rotatably connected to the rotation connection section 22 in a separable manner, the first threaded connection section 12 is threadedly connected to the second threaded connection section 21, and the operating abutment section 11 is used to play a role of abutment limiting and is used to operate and drive the abutment member 1 to rotate.
[0028] Correspondingly, the first threaded connection section 12 is cylindrical and has an external thread 121 on its outer surface, the second threaded connection section 21 is cylindrical and has a connecting hole 211 therein, and the inner surface of the connecting hole 211 is provided with an internal thread 212 that is compatible with the external thread 121, thereby facilitating the threaded connection between the first threaded connection section 12 and the second threaded connection section 21.
[0029] In addition, the operating abutment section 11 is in the shape of a stepped boss and includes an abutment circular plate 111 and an embedded circular plate 112. The center of the outer end surface of the abutment circular plate 111 is provided with an operating slot 1111, so that it is convenient to use a corresponding tool to insert the operating slot 1111 and drive the abutment member 1 to rotate. Preferably, the operating slot 1111 is in the shape of a plum blossom slot, so that when the abutment member 1 is rotated, it is less likely to slip. The outer diameter of the abutment circular plate 111 is greater than The outer diameter of the embedded circular plate 112 is consistent with the outer diameter of the sleeve 2. In addition, the outer diameter of the embedded circular plate 112 and the outer diameter of the sleeve 2 are also adapted to the inner diameter of the mounting hole 61 of the column 6, so that when the adjustable tensioner is installed in the mounting hole 61 of the column 6, the abutting circular plate 111 can abut against the outer surface of the column 6 to cooperate with the tensioning of the cable 5, so that the adjustable tensioner can be stably installed on the column 6. In addition, the embedded circular plate 112 can be embedded in the mounting hole 61 to further improve the stability during installation.
[0030] The rotating connecting section 22 is semi-cylindrical and has an open accommodating cavity 221 formed therein for accommodating the fixing rod 3. Two symmetrical convex shafts 31 are fixedly provided on the outer surface of one end of the fixing rod 3. The rotating connecting section 22 is provided with two symmetrical grooves 222 on both sides of the accommodating cavity 221. The grooves 222 are provided on the rotating connecting section 22 at one end away from the second threaded connecting section 21. The two convex shafts 31 correspond to the two grooves 222 one by one. The convex shafts 31 are detachably and rotatably provided in the corresponding grooves 222, thereby facilitating the detachable rotating connection between the fixing rod 3 and the sleeve 2.
[0031] Preferably, the groove 222 includes a circular rotating hole 2221 and a square entrance 2222 which are connected to each other. The convex shaft 31 is in the shape of a square column. The width of the convex shaft 31 is matched with the width of the square entrance 2222. In this way, the convex shaft 31 is allowed to rotate in the circular rotating hole 2221, and the convex shaft 31 is allowed to enter the circular rotating hole 2221 through the square entrance 2222. At the same time, when the convex shaft 31 is rotated by an appropriate angle, since the diagonal length of the convex shaft 31 is greater than the width of the square entrance 2222, the convex shaft 31 can be effectively prevented from escaping from the circular rotating hole 2221.
[0032] The rotating connecting section 22 is provided with two symmetrical planar cut surfaces 223 on the outer surface of one end away from the second threaded connecting section 21. The two planar cut surfaces 223 can be clamped in cooperation with a clamping tool so that the clamping tool is clamped on the two planar cut surfaces 223, thereby stably clamping the sleeve 2 to effectively prevent the sleeve 2 from rotating following the rotation of the abutment member 1.
[0033] The outer surface of the rotating connecting section 22 at one end away from the second threaded connecting section 21 is provided with a notch 224 for the cable 5 to pass through, so as to effectively prevent the cable 5 from interfering with the sleeve 2 when the cable 5 is installed at an angle.
[0034] The fixing rod 3 is provided with a threading hole 32 for the cable 5 to pass through, and the fixing rod 3 is provided with a locking mechanism 4 for locking and fixing the cable 5. The locking mechanism 4 includes at least one locking screw 41. The outer circumferential surface of the fixing rod 3 is provided with at least one locking hole 42 that communicates with the threading hole 32. The locking screw 41 is detachably threadedly connected to the locking hole 42. Preferably, there are three locking holes 42. In other embodiments, the number of the locking holes 42 can also be 1, 2 or 4. The three locking holes 42 are spaced apart along the circumference of the fixing rod 3, and two adjacent locking holes 42 are arranged along the circumference of the fixing rod 3. The circumference of the fixing rod 3 is arranged at 90 degrees or 180 degrees to each other, and the distances from the three locking holes 42 to the end of the fixing rod 3 are increased successively. In addition, the spacing between two adjacent locking holes 42 is equal. Therefore, when one end of the cable 5 is inserted into the threading hole 32 of the fixing rod 3, the three locking screws 41 can be tightened in the corresponding locking holes 42 respectively, and the cable 5 can be squeezed, and the cable 5 inserted in the threading hole 32 is made S-shaped to ensure its locking and fixing effect, thereby ensuring the stability and reliability of the connection between the fixing rod 3 and the cable 5. At the same time, it is easy to disassemble and assemble and can be reused.
[0035] Preferably, the locking screw 41 is of a hexagonal head type, so that the thread slipping problem is less likely to occur when the locking screw 4121 is disassembled and assembled.
[0036] In addition, the threading holes 32 pass through both ends of the fixing rod 3 .
[0037] A guardrail comprises a cable 5, at least two posts 6 and at least one adjustable tensioner as described in any one of the above items, wherein the post 6 is provided with at least one mounting hole 61 penetrating through the end faces on both sides thereof, at least one end of the cable 5 is connected to the corresponding adjustable tensioner, and the adjustable tensioner penetrates into the mounting hole 61 of the post 6 and is installed in the post 6 and tensions the cable 5.
[0038] Preferably, the cable 5 is a steel wire rope or a cable 5 made of other materials.
[0039] In this embodiment, there is one adjustable tensioner, one end of the cable 5 is connected to the adjustable tensioner to adjust the tension of the cable 5 from one end thereof, and the other end of the cable 5 can be connected to the cable holder 7, which can be applied to horizontal scenes or stair inclined scenes. When applied to stair inclined scenes, the inclination angle of the cable 5 can be set according to actual needs. The cable holder 7 is only used to connect and fix the other end of the cable 5, and can adopt the structure in the prior art, so that the adjustable tensioner can be used in conjunction with different cable holders 7. In other embodiments, there are two adjustable tensioners, and both ends of the cable 5 are respectively connected to the corresponding adjustable tensioners, which can be applied to horizontal scenes.
[0040] The locking mechanism 4 is used to lock and fix the cable 5 inserted into the threading hole 32 of the fixing rod 3, which can effectively ensure the stability and reliability of the connection between the cable 5 and the fixing rod 3. There is no need to use an additional pressing tool to crimp the fixing rod 3 and the cable 5 to compress the cable 5. At the same time, the adjustable tensioner can be reused and is easy to install and disassemble. After the adjustable tensioner is installed, the abutment member 1, the sleeve 2 and most of the structures of the fixing rod 3 are located in the inner cavity of the column 6, so as to play a corresponding hiding role, effectively ensuring the aesthetic appearance of the overall appearance of the adjustable tensioner after installation; by driving the abutment member 1 to rotate, the sleeve 2 can be moved relative to the abutment member 1, and the fixing rod 3 can be driven to move together, so as to facilitate the tightening or loosening of the cable 5; by setting the fixing rod 3 to be detachably connected to the sleeve 2, the inclination angle of the fixing rod 3 can be adjusted to adapt to the installation of cables 5 with different inclination angles, which can be applied to horizontal scenes or stair inclination scenes.
[0041] The method of using the adjustable tensioner and the guardrail described in the utility model is as follows:
[0042] Insert one end of the cable 5 into the threading hole 32 of the fixing rod 3;
[0043] Use the locking screw 41 to tighten into the corresponding locking hole 42 on the fixing rod 3 to lock and fix one end of the cable 5;
[0044] Place the fixing rod 3 in the accommodating cavity 221 of the sleeve 2, and make the two protruding shafts 31 on the fixing rod 3 respectively fit into the two grooves 222 of the sleeve 2, and make the central axis of the fixing rod 3 nearly coincide with the central axis of the sleeve 2;
[0045] Insert the sleeve 2 together with the fixing rod 3 from one end of the mounting hole 61 on the column 6 into the cavity of the column 6, and insert the abutting member 1 from the other end of the mounting hole 61 on the column 6 into the cavity of the column 6, and then make the first threaded connection section 12 of the abutting member 1 and the second threaded connection section 21 of the sleeve 2 preliminarily threadedly connected, and make the embedded circular plate 112 embedded in the mounting hole 61, and make the abutting circular plate 111 abut against the outer surface of the column 6, at the same time, according to the inclination angle requirement of the cable 5, the fixing rod 3 can be adaptively rotated to a suitable inclination angle;
[0046] Use the corresponding clamping tool to clamp on the two flat cut surfaces 223 of the sleeve 2, so as to stably clamp the sleeve 2 and prevent it from rotating. Then use the L-shaped plum blossom hexagonal wrench to insert into the operating slot 1111 of the abutment 1, and drive the abutment 1 to rotate, so that the sleeve 2 moves relative to the abutment 1 toward the side of the abutment 1, and drives the fixing rod 3 to move together, so as to achieve the tightening of the cable 5.
[0047] It should be understood that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made and that such a development effort may be complex and time-consuming, but will be a routine task of design, manufacturing, and production for those of ordinary skill having the benefit of this disclosure without undue experimentation.
[0048] The above are only some specific implementation methods of the utility model, but the design concept of the utility model is not limited to this. Any non-substantial changes to the utility model using this concept shall be deemed as an infringement of the protection scope of the utility model.
