DETAILED DESCRIPTION

[0022] The present invention is further described below through specific implementation methods.

[0023] like Figures 1 to 6 As shown, a connection tensioner described in the utility model comprises at least one fixing component 1 and at least one tensioning component 2.

[0024] In one embodiment, two ends of the steel wire rope 4 can be connected using a fixing component 1 and a tensioning component 2 respectively, and the fixing component 1 and the tensioning component 2 are respectively arranged on two mounting columns 3.

[0025] In another embodiment, one tensioning assembly 2 can be used to connect both ends of the steel wire rope 4 , and two tensioning assemblies 2 are respectively disposed on two mounting posts 3 .

[0026] The fixing assembly 1 includes a first mounting buckle 12 and a crimping rod 11 fixedly crimped to one end of the steel wire rope 4. The crimping rod 11 is installed on the corresponding mounting column 3 through the first mounting buckle 12. In addition, the crimping rod 11 can be made of metal material, such as stainless steel or aluminum.

[0027] The first mounting buckle 12 is in the shape of a ram's horn and has a first C-shaped connecting hole 121 formed in the middle thereof. A first notch 122 communicating with the first connecting hole 121 is provided in the middle of the outer circumferential surface of the first mounting buckle 12. First countersunk holes 123 are provided at both ends of the first mounting buckle 12, so that the first mounting buckle 12 can be locked and fixed to the corresponding mounting column 3 at the first countersunk holes 123 using self-tapping screws. One end of the crimping rod 11 is in the shape of a hammer head and has a first cylindrical connecting shaft 111. The first connecting shaft 111 is adapted to the first connecting hole 121 and can be rotatably installed in the first connecting hole 121. Inside, the other end of the crimping rod 11 is a light rod 112, and one end of the light rod 112 passes through the first notch 122, thereby facilitating the stable installation of the crimping rod 11 on the first mounting buckle 12, and after installation, the installation position of the crimping rod 11 can be flipped relative to the first mounting buckle 12 to better adapt to the installation of the wire rope 4 with different inclined installation angles, and a first crimping cavity 1121 is provided in the light rod 112, thereby, one end of the wire rope 4 can pass through the first crimping cavity 1121, and then the light rod 112 is crimped, so as to achieve a stable connection between the crimping rod 11 and the wire rope 4.

[0028] The tensioning assembly 2 includes a second mounting buckle 24, a locking nut 25, a connecting piece 21, a tensioning sleeve 22 and a crimping sleeve 23 fixedly crimped to one end of the wire rope 4. The connecting piece 21 is installed on the corresponding mounting column 3 through the second mounting buckle 24. In addition, the crimping sleeve 23 can be made of metal material, such as stainless steel or aluminum.

[0029] The tensioning sleeve 22 is provided with a tensioning cavity 221 passing through both ends thereof, the connecting piece 21 is threadedly connected to one end of the tensioning sleeve 22, the crimping sleeve 23 is detachably sleeved in the tensioning cavity 221 and clamped on the other end of the tensioning sleeve 22, and the tensioning sleeve 22 is provided with a rotating operating part 223. Preferably, the rotating operating part 223 is a through hole, and the through hole passes through the outer peripheral surface of the tensioning sleeve 22. In this way, a first fastening tool can be inserted into the through hole of the tensioning sleeve 22 to easily and conveniently perform a subsequent rotation operation on the tensioning sleeve 22.

[0030] The second mounting buckle 24 is in the shape of a ram's horn and has a second C-shaped connecting hole 241 formed in the middle thereof. A second notch 242 communicating with the second connecting hole 241 is provided in the middle of the outer circumferential surface of the second mounting buckle 24. Second countersunk holes 243 are provided at both ends of the second mounting buckle 24, so that the second mounting buckle 24 can be locked and fixed to the corresponding mounting column 3 at the second countersunk holes 243 using self-tapping screws. One end of the connecting member 21 is in the shape of a hammer head and has a cylindrical second connecting shaft 211. The second connecting shaft 211 is adapted to the second connecting hole 241 and can be rotatably installed in the second connecting hole 241. The other end of the connecting member 21 is a screw 212. One end of the screw rod 212 passes through the second notch 242, thereby facilitating the stable installation of the connecting member 21 on the second mounting buckle 24, and after installation, the installation position of the connecting member 21 can be flipped relative to the second mounting buckle 24 to better adapt to the installation of the wire rope 4 with different inclined installation angles. An external thread section 2121 is provided on the outer peripheral surface of the screw rod 212, and an internal thread section 224 matched with the external thread section 2121 is provided on the inner surface of one end of the tightening cavity 221 of the tightening sleeve 22, so as to realize the threaded connection between the connecting member 21 and the tightening sleeve 22, thereby facilitating the tightening of the wire rope 4 by tightening the tightening sleeve 22.

[0031] The locking nut 25 is threadedly connected to the external threaded section 2121 of the screw rod 212. After the wire rope 4 is pulled to a suitable pound through the tensioning sleeve 22, the locking nut 25 can be tightened to lock and fix the tensioning sleeve 22 to stabilize the pound of the wire rope 4. Specifically, the locking nut 25 is located between the second connecting shaft 211 and the tensioning sleeve 22. The locking nut 25 can fix the screw-in distance between the tensioning sleeve 22 and the external threaded section 2121 of the screw rod 212, thereby further controlling the length and locking degree of the wire rope 4.

[0032] The crimping sleeve 23 includes a crimping section 231, an annular protrusion 232 fixedly arranged on the outer surface of one end of the crimping section 231, and an operating section 233 fixedly connected to one end of the crimping section 231 provided with the annular protrusion 232. The crimping section 231 is provided with a second crimping cavity 2311 penetrating both ends thereof, so that one end of the steel wire rope 4 can be inserted into the second crimping cavity 2311, and then the crimping section 231 of the crimping sleeve 23 is crimped. In this way, a stable connection between the crimping sleeve 23 and the steel wire rope 4 is achieved. An annular stopper 222 is fixedly arranged on the inner surface of one end of the tightening cavity 221 of the tightening sleeve 22. The outer diameter of the annular stopper 232 is larger than the inner diameter of the annular stopper 222, and the outer diameter of the annular stopper 232 is smaller than the inner diameter of the tightening cavity 221. In this way, a stable connection between the crimping sleeve 23 and the tightening sleeve 22 can be achieved, so that the crimping sleeve 23 and the tightening sleeve 22 are stably connected. The sleeves 22 are rigidly connected to ensure the tensioning force of the wire rope 4. At the same time, the crimping section 231 of the crimping sleeve 23 can be stably located in the tensioning cavity 221 of the tensioning sleeve 22, so that the crimping portion between the crimping sleeve 23 and the wire rope 4 is well hidden in the tensioning sleeve 22. In addition, the operating section 233 passes through the tensioning cavity 221 of the tensioning sleeve 22, and a cavity 2331 is provided in the operating section 233 which runs through both ends and communicates with the second crimping cavity 2311. Two symmetrically arranged operating planes 2332 are provided on the outer peripheral surface of the operating section 233. Therefore, the second fastener is clamped on the two operating planes 2332 of the crimping sleeve 23 to play a corresponding positioning role for the crimping sleeve 23, so as to effectively prevent the crimping sleeve 23 and the wire rope 4 from rotating with the rotation of the tensioning sleeve 22 when the tensioning sleeve 22 is rotated.

[0033] By adopting this design method, the length of the wire rope 4 can be better controlled and the tension of the wire rope 4 can be adjusted. The overall structure and size of the wire rope 4 connected to the tensioner can be made smaller, the number of parts can be reduced, which is beneficial to reducing the overall processing cost and material cost, and the crimping part between the crimping sleeve 23 and the wire rope 4 can be well hidden in the tensioning sleeve 22, making the overall appearance more beautiful.

[0034] The method for using the connection tensioner described in the utility model is as follows:

The second connecting shaft 211 is installed in the second connecting hole 241 of the second mounting buckle 24, and the screw rod 212 of the connecting member 21 is passed through the second notch 242 of the second mounting buckle 24. The second mounting buckle 24 is locked and fixed on the mounting column 3 using a self-tapping screw, and the locking nut 25 is screwed onto the screw rod 212. After determining the length of the wire rope 4, the other end of the wire rope 4 is inserted into the first crimping cavity 1121 of the crimping rod 11, and the wire rope 4 is crimped. The first connecting shaft 111 of 11 is installed in the first connecting hole 121 of the first mounting buckle 12, and the bare rod 112 of the crimping rod 11 is passed through the first notch 122 of the first mounting buckle 12, and the first mounting buckle 12 is locked and fixed on the mounting column 3 using a self-tapping screw, and the tensioning sleeve 22 is preliminarily threadedly connected with the external threaded section 2121 of the screw rod 212 through the internal threaded section 224, and then, the first fastening tool is inserted into the through hole of the tensioning sleeve 22, and is clamped on the two operating planes 2332 of the crimping sleeve 23 through the second fastener, and then the tensioning sleeve 22 is driven to rotate by the first fastening tool, thereby tightening the tensioning sleeve 22 and tightening the wire rope 4. After tightening the wire rope 4, the locking nut 25 is tightened to lock and fix the tensioning sleeve 22 to stabilize the poundage of the wire rope 4, thereby controlling the length and tension of the wire rope 4 by adjusting the tensioning sleeve 22 and the locking nut 25.

[0037] In another embodiment, two ends of the steel wire rope 4 are connected to two mounting posts 3 respectively using two tensioning assemblies 2, and both ends of the steel wire rope 4 can be tensioned.

[0038] During installation, one end of the steel wire rope 4 is passed through the tensioning cavity 221 of the tensioning sleeve 22 of one of the tensioning components 2, and then passed into the second crimping cavity 2311 of the crimping sleeve 23 and crimped with the steel wire rope 4 at the crimping section 231, and then the crimping sleeve 23 is placed in the tensioning cavity 221 of the tensioning sleeve 22, and the annular protrusion 232 of the crimping sleeve 23 is abutted against the annular limit block 222 of the tensioning sleeve 22, and the operating section 233 of the crimping sleeve 23 passes through the tensioning sleeve 22, and the second connecting shaft 211 of the connecting member 21 is installed in the second connecting hole 241 of the second mounting buckle 24 , and make the screw 212 of the connecting member 21 pass through the second notch 242 of the second mounting buckle 24, use the self-tapping screw to lock and fix the second mounting buckle 24 on the mounting column 3, and screw the locking nut 25 onto the screw 212. After determining the length of the wire rope 4, insert the other end of the wire rope 4 into the tightening cavity 221 of the tightening sleeve 22 of another tightening component 2, and then insert it into the second crimping cavity 2311 of the crimping sleeve 23 and crimp the wire rope 4 at the crimping section 231, then put the crimping sleeve 23 into the tightening cavity 221 of the tightening sleeve 22, and make the annular shape of the crimping sleeve 23 The protrusion 232 abuts against the annular stop block 222 of the tension sleeve 22, and the operating section 233 of the crimping sleeve 23 passes through the tension sleeve 22, the second connecting shaft 211 of the connecting member 21 is installed in the second connecting hole 241 of the second mounting buckle 24, and the screw 212 of the connecting member 21 passes through the second notch 242 of the second mounting buckle 24, the second mounting buckle 24 is locked and fixed on the mounting column 3 with a self-tapping screw, and the locking nut 25 is screwed onto the screw 212, and the tension sleeves 22 of the two tensioning components 2 are connected to the outer thread section 224 of the screw 212.
