All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] Depend on Figure 1 , Figure 2 and Figure 3 This invention discloses a tensile testing device for rigging. A double-ended screw 101 is rotatably connected to the left and right side walls of the inner cavity of a test chamber 100. The double-ended screw 101 facilitates the movement of two sets of movable frames 102 towards or away from each other. The right end of the double-ended screw 101 penetrates the right side wall of the test chamber 100 and is equipped with a handle, which facilitates the rotation of the double-ended screw 101. Movable frames 102 are screwed to both the left and right sides of the outer wall of the double-ended screw 101. The movable frames 102 facilitate the rotation of connecting rods 103. The movable frames 102 move along the bottom wall of the inner cavity of the test chamber 100 to prevent deflection. Connecting rods 103 are rotatably connected to the top of each movable frame 102. The lifting plate 104 is easily moved up and down by the connecting rod 103. The inner wall of the test chamber 100 is slidably connected to the lifting plate 104. The lifting plate 104 facilitates the lifting and lowering of the fixed hook 105 and the test mechanism 106. The top of the lifting plate 104 is evenly provided with through holes to facilitate the flow of liquid. The other end of the connecting rod 103 is provided on the bottom wall of the lifting plate 104. The left side of the top wall of the lifting plate 104 is fixedly connected to the fixed hook 105 to facilitate the installation of rigging. The test mechanism 106 is installed on the right side of the top of the lifting plate 104. The front side wall of the test chamber 100 is provided with a drain outlet to facilitate the discharge of liquid.

[0021] In this embodiment: Water is injected into the inner cavity of the test chamber 100. The rigging to be tested is hung on the fixed hook 105 and the test mechanism 106. The double-headed screw 101 is rotated by turning the handle. The double-headed screw 101 drives the two sets of moving frames 102 to move towards each other or the pressure plate to move. The moving frames 102 drive the connecting rod 103 to rotate. The rotation of the connecting rod 103 facilitates the movement of the lifting plate 104. When the lifting plate 104 moves down, it drives the fixed hook 105 and the test mechanism 106 to move. The fixed hook 105 and the test mechanism 106 drive the rigging to be tested to move down. The water in the test chamber 100 flows out from the through hole until the rigging is submerged. The test mechanism 106 tests the tensile force of the rigging. The lifting plate 104 is raised above the water surface to facilitate tensile force testing in the air. This device can be used to test the tensile force of rigging in liquids or in the air, making it more applicable and improving the practicality of the device.

[0022] The testing mechanism 106 includes a fixed frame 107. The left and right side walls of the inner cavity of the fixed frame 107 are rotatably connected to a lead screw 108, which facilitates the movement of the traction frame 109. The traction frame 109 is screwed to the outer wall of the lead screw 108. The fixed frame 107 limits and guides the movement of the traction frame 109. The traction frame 109 facilitates the movement of the tensile testing element 110. The tensile testing element 110 is fixedly connected to the left side wall of the traction frame 109. In the underwater tensile testing of the rigging, the tensile testing element 110 plays a key role. The resistance strain gauge works based on the strain effect of metal or semiconductor materials. When the rigging is subjected to tensile force and deforms, the strain gauge attached to the surface of the rigging will also deform, causing its resistance value to change. By measuring the change in resistance value, and through the corresponding conversion circuit and calculation, the magnitude of the tension that the rigging can be determined. The test end of the tension testing element 110 is fixedly connected to a pull hook 111, and the other end of the rigging is installed through the pull hook 111.

[0023] In this embodiment: the traction frame 109 is moved by rotating the lead screw 108, the tension testing element 110 is moved by the traction frame 109, the tension testing element 110 is moved by the tension hook 111, and the tension testing of the rigging is performed by moving the tension hook 111. This makes it easier to pull the rigging and perform tension testing on the rigging, which is beneficial for measuring tension data in air and water.

[0024] The right end of the lead screw 108 passes through the right side wall of the fixed frame 107 and is fixedly connected to the first bevel gear 112. The first bevel gear 112 facilitates the rotation of the lead screw 108. The right side of the top wall of the lifting plate 104 is fixedly connected to the connecting frame 113, which facilitates the support of the motor 114. The top wall of the connecting frame 113 is equipped with the motor 114, which facilitates the rotation of the second bevel gear 115. The top wall of the inner cavity of the connecting frame 113 is fixedly connected to the second bevel gear 115, which facilitates the rotation of the first bevel gear 112. The second bevel gear 115 is fixedly connected to the output end of the motor 114.

[0025] In this embodiment: the motor 114 facilitates the rotation of the second bevel gear 115, which in turn drives the first bevel gear 112 to rotate, and the first bevel gear 112 drives the lead screw 108 to rotate. This facilitates the transmission of the device. The connecting frame 113 supports the motor 114 and supports it, preventing it from coming into contact with liquid and causing corrosion, which is beneficial to the practicality of the device.

[0026] The left and right side walls of the inner cavity of the test chamber 100 are fixedly connected with slide bars 116. The slide bars 116 facilitate the limiting and guiding of the movement of the lifting plate 104. The left and right side walls of the lifting plate 104 are provided with slide grooves, and the slide bars 116 are located in the inner cavity of the slide grooves.

[0027] In this embodiment, the slide bar 116 is set to limit and guide the movement of the lifting plate 104, prevent the lifting plate 104 from deflecting, facilitate the translation and lifting of the lifting plate 104, and facilitate the lifting and moving of the rigging.

[0028] The top wall of the lifting plate 104 is uniformly fixedly connected with a blocking cap 117. The blocking cap 117 is used to block the sprayed water flow. The outer wall of the blocking cap 117 is uniformly provided with liquid outlet grooves. The blocking cap 117 is located at the through hole.

[0029] In this embodiment, the blocking cap 117 is used to block the liquid sprayed from the through hole, preventing the sprayed liquid from spraying out of the inner cavity of the test chamber 100, making it easier to immerse the rigging in the liquid and improving the practicality of the device.
