Description

Technical Field

[0001] This utility model relates to the field of cable tensile testing technology, and in particular to a cable tensile testing device. Background Technology

[0002] Cable tensile testing involves applying axial tension to a cable using specific equipment and methods to determine its performance under different tensile forces, including the maximum tensile force it can withstand and the elongation during the stretching process. This allows for the assessment of the cable's strength, toughness, and whether it meets relevant quality standards and usage requirements.

[0003] A patent document with publication number CN206683958U discloses a cable tensile testing device, including a testing base. A display device is mounted on the upper end of the testing base. A fixed clamping plate is mounted on the testing base next to the display device, and a movable clamping plate is mounted on the testing base on the side of the fixed clamping plate away from the display device. The fixed and movable clamping plates are arranged opposite each other and both have cable fixing holes along the same straight line in the same horizontal plane. A locking handle is mounted on each cable fixing hole. A testing cable is connected to the cable fixing hole between the fixed and movable clamping plates. During testing, a cylinder provides tensile force. When the cable cannot withstand the tensile force and suddenly breaks, the movable clamping plate quickly moves towards the cylinder mounting seat. Through the setting of a buffer spring and a buffer plate, the impact force of the movable clamping plate is quickly dissipated, preventing damage to the testing device and improving the service life of the equipment.

[0004] The above and existing technologies have the following defects: when the cable breaks during the tensile test, the broken cable fragments are scattered, which damage the surrounding instruments and cause obvious scratches on the surface of the instruments. In severe cases, the protective coating or paint layer on the surface may even be worn away, affecting the appearance of the instruments.

[0005] Therefore, a cable tensile testing device is proposed. Utility Model Content

[0006] The purpose of this invention is to address the problem that when a cable breaks during a tensile test, the broken cable fragments scatter and damage surrounding equipment, causing obvious scratches on the surface of the equipment.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a cable tensile testing device, comprising a base plate, an output box mounted on the surface of the base plate, a buffer mounted on the surface of the output box, a tensioner mounted on the surface of the buffer, a cable wire mounted on the surface of the tensioner, an operation box mounted on the surface of the base plate, a protective device provided on the surface of the tensioner, the protective device comprising a groove, the groove being formed on the surface of the tensioner, a slider slidably connected to the surface of the groove, a lead screw rotatably connected to the surface of the slider, a screw hole rotatably connected to the arc surface of the lead screw, the screw hole being formed on the surface of the tensioner, and a telescopic plate fixedly connected to the surface of the slider, the telescopic plate being adapted to the size of the cable wire.

[0008] The effect achieved by the above components is as follows: by setting up a protective device, and utilizing the cooperation between the groove, slide bar, lead screw, screw hole and telescopic plate, the cable to be tested can be protected in real time, avoiding the moment when the cable breaks during the tensile test. The broken cable will splash out and damage the surrounding instruments, causing obvious scratches on the surface of the instruments. In severe cases, it may even wear away the protective coating or paint layer on the surface, affecting the appearance of the instruments, thus improving the protection effect on the surrounding instruments.

[0009] Preferably, the surface of the slider is rotatably connected to a ball bearing, and the ball bearing is slidably connected to the groove.

[0010] The effect achieved by the above components is that the slider will drive the ball to roll along the surface of the groove, at which time the ball can reduce the friction between the slider and the groove.

[0011] Preferably, a sealing gasket, which is a rubber gasket, is fixedly connected to the surface of the telescopic plate.

[0012] The effect achieved by the above components is that the telescopic plate will drive the sealing gasket to move. At this time, the rubber sealing gasket can increase the sealing between the two telescopic plates when they come into contact.

[0013] Preferably, a handle is fixedly connected to one end of the lead screw, and the cross-section of the handle is in the shape of a straight line.

[0014] The effect achieved by the above components is that when the handle is turned, the handle will drive the lead screw to rotate along the screw hole, and at this time the handle can easily rotate the lead screw.

[0015] Preferably, the surface of the operating box is provided with an auxiliary device, the auxiliary device including a fixing plate, the fixing plate being fixedly connected to the operating box, a pin being slidably connected to the surface of the fixing plate, a limit plate being slidably connected to the arc surface of the pin, a baffle being fixedly connected to the surface of the limit plate, and an observation plate being fixedly connected to the surface of the baffle.

[0016] The effect achieved by the above components is as follows: by setting up auxiliary devices, and by using the cooperation between the fixing plate, the pin, the limiting plate, the cover and the observation plate, the buttons on the control box can be blocked, so as to avoid accidentally touching the buttons on the control box during the cable tension test, which would cause the test data to deviate and improve the data accuracy during the cable tension test.

[0017] Preferably, a spring is fitted onto the arc surface of the pin, and the two ends of the spring are fixedly connected to the fixing plate and the pin, respectively.

[0018] The effect achieved by the above components is that the pin will drive one end of the spring to move, and at the same time the spring itself will generate a retracting force, which will help the pin to quickly return to its original position.

[0019] Preferably, one end of the pin is fixedly connected to a pointed cone, which is a stainless steel cone.

[0020] The effect achieved by the above components is that the pin will drive the cone to move, at which time the cone can easily pass through the limiting plate.

[0030] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0031] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0032] like Figures 1-5 As shown, this utility model provides a cable tensile testing device, including a base plate 1, an output box 2 mounted on the surface of the base plate 1, a buffer 3 mounted on the surface of the output box 2, a tensioner 4 mounted on the surface of the buffer 3, cable wires 5 mounted on the surface of the tensioner 4, an operation box 6 mounted on the surface of the base plate 1, a protective device 7 provided on the surface of the tensioner 4, and an auxiliary device 8 provided on the surface of the operation box 6.

[0033] The specific settings and functions of its protective device 7 and auxiliary device 8 will be described in detail below.

[0034] like Figures 2-4As shown, the protective device 7 includes a groove 71, which is formed on the surface of the tensioner 4. A slider 72 is slidably connected to the surface of the groove 71, and a lead screw 73 is rotatably connected to the surface of the slider 72. A screw hole 74 is rotatably connected to the arc surface of the lead screw 73, which is formed on the surface of the tensioner 4. A telescopic plate 75 is fixedly connected to the surface of the slider 72, and the telescopic plate 75 is adapted to the size of the cable wire 5. A ball bearing 76 is rotatably connected to the surface of the slider 72, and the ball bearing 76 is slidably connected to the groove 71. The slider 72 will drive the ball bearing 76 to roll along the surface of the groove 71. At this time, the ball bearing 76... 6 can reduce the friction between the slider 72 and the groove 71. A sealing gasket 77 is fixedly connected to the surface of the telescopic plate 75. The sealing gasket 77 is a rubber gasket. The telescopic plate 75 will drive the sealing gasket 77 to move. At this time, the rubber sealing gasket 77 can increase the sealing between the two telescopic plates 75 when they are in contact. A handle 78 is fixedly connected to one end of the screw 73. The cross-section of the handle 78 is I-shaped. When the handle 78 is rotated, the handle 78 will drive the screw 73 to rotate along the screw hole 74. At this time, the handle 78 can easily rotate the screw 73.

[0035] like Figure 2 and Figure 5 As shown, the auxiliary device 8 includes a fixed plate 81, which is fixedly connected to the operation box 6. A pin 82 is slidably connected to the surface of the fixed plate 81. A limit plate 83 is slidably connected to the arc surface of the pin 82. A cover 84 is fixedly connected to the surface of the limit plate 83. An observation plate 85 is fixedly connected to the surface of the cover 84. A spring 86 is sleeved on the arc surface of the pin 82. The two ends of the spring 86 are fixedly connected to the fixed plate 81 and the pin 82, respectively. The pin 82 will drive one end of the spring 86 to move. At the same time, the spring 86 itself will generate a retraction force. At this time, the spring 86 can help the pin 82 to quickly reset. A pointed cone 87 is fixedly connected to one end of the pin 82. The pointed cone 87 is a stainless steel cone. The pin 82 will drive the pointed cone 87 to move. At this time, the pointed cone 87 can facilitate the pin 82 to pass through the limit plate 83.

[0036] The overall working principle is as follows: When it is necessary to protect the cable wire 5 being tested, the handle 78 can be rotated. The handle 78 will then drive the lead screw 73 to rotate along the screw hole 74. At this time, the handle 78 can easily rotate the lead screw 73. Then, the lead screw 73 will move towards the tensioner 4 using its own thread. Then, the lead screw 73 will drive the slider 72 to slide along the surface of the groove 71. At the same time, the slider 72 will drive the ball 76 to roll along the surface of the groove 71. At this time, the ball 76 can reduce the friction between the slider 72 and the groove 71. Then, the slider 72 will drive the arc-shaped telescopic plate 75 to move towards the cable wire 5. Then, the telescopic plate 75 will drive the sealing... The pad 77 moves, and the rubber sealing pad 77 increases the sealing between the two telescopic plates 75 when they come into contact. Then the tensioner 4 can be activated to test the tension of the cable 5. By setting up the protective device 7, and utilizing the cooperation between the groove 71, slide rod, lead rod 73, screw hole 74 and telescopic plate 75, the cable 5 to be tested can be protected in real time. This avoids the cable 5 from breaking at the moment of breakage during the tension test. The broken cable 5 would splash and damage the surrounding instruments, causing obvious scratches on the surface of the instruments. In severe cases, it may even wear away the protective coating or paint layer on the surface, affecting the appearance of the instruments and improving the protection effect on the surrounding instruments.

[0037] When it is necessary to click the button on the control box 6, the pin 82 can be pulled away from the fixed plate 81. The pin 82 will then move one end of the spring 86, and the spring 86 will generate a retraction force. At this time, the spring 86 can help the pin 82 quickly return to its original position. Then the pin 82 will disengage from the limiting plate 83 along the fixed plate 81. Then the cover 84 can be moved away from the control box 6. Next, the cover 84 will move the observation plate 85. When the cover 84 is no longer in contact with the control box 6, the button on the control box 6 can be operated. When it is necessary to block the button, the cover 84 can be pressed towards the control box 6. The cover 84 will then move the limiting plate 83. Then the limiting plate 85 will move away from the control box 6. When the position of the fixed plate 81 coincides with that of the fixed plate 81, the spring 86 can be released. Then, the spring 86 will use its own tension to move the pin 82 towards the limit plate 83. At the same time, the pin 82 will drive the cone 87 to move. At this time, the cone 87 can facilitate the pin 82 to pass through the limit plate 83. When the pin 82 passes through the limit plate 83, the position of the limit plate 83 and the fixed plate 81 can be restricted. By setting the auxiliary device 8, the buttons on the operation box 6 can be blocked by the cooperation between the fixed plate 81, the pin 82, the limit plate 83, the cover 84 and the observation plate 85. This avoids accidentally touching the buttons on the operation box 6 during the tension detection of the cable 5, which would cause the detection data to deviate and improve the data accuracy during the tension detection of the cable 5.

[0038] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
