[0034] Please see Figures 1-6 As shown, this utility model is a manual pressing device for a cable filler rope traction machine, including a fixed base 1. A support assembly 2 and a limiting assembly 3 are respectively provided on the fixed base 1. A second roller 4 is rotatably connected to the top of the fixed base 1. A fixed frame 5 is connected to the top of the fixed base 1. A rubber handle 6 is rotatably connected to the inner side of the fixed frame 5. One end of the rubber handle 6 is connected to a main bevel gear 7. A secondary bevel gear 8 is rotatably connected to the inner side of the top of the fixed frame 5.

[0035] The main bevel gear 7 is in meshing connection with the secondary bevel gear 8, the bottom end of the secondary bevel gear 8 is connected with the adjusting screw rod 9, the surface of the adjusting screw rod 9 is connected with the adjusting block 10 through screw nut thread, the inner wall of the fixed frame 5 is connected with the connecting frame 11, one side of the connecting frame 11 is in rotary connection with one side of the second roller body 4;

[0036] The surface of the supporting assembly 2 is connected with the inner side of the fixed seat 1, so as to drive the supporting assembly 2 to make lifting adjustment in the vertical direction through the elastic contraction effect;

[0037] The surface of the limiting assembly 3 is connected with the inside of the fixed seat 1, so as to limit the supporting assembly 2.

[0038] Firstly, when the supporting assembly 2 needs to be manually compressed, the operator holds the rubber handle 6 and rotates the rubber handle 6, so as to drive the main bevel gear 7 and the secondary bevel gear 8 to rotate in meshing, and then drive the adjusting screw rod 9 to drive the adjusting block 10 to descend, through the elastic contraction effect of the supporting assembly 2 itself, the supporting assembly 2 itself has a vertical downward driving force, so that the operator can press the supporting assembly 2 according to the required compression force, which is relatively easy, after adjusting the compression force, in order to prevent the supporting assembly 2 and the adjusting block 10 from moving upward and resetting, the limiting assembly 3 is driven to work, through the translational movement of the limiting assembly 3 and the supporting assembly 2, the supporting assembly 2 is positioned, avoiding the contraction effect of the supporting assembly 2 again, and then avoiding the upward movement of the supporting assembly 2 and the adjusting block 10, so that the compression force is fixed and has good stability, similarly, when the supporting assembly 2 needs to move upward under strong compression force, after rotating the rubber handle 6 to drive the supporting assembly 2 to move upward, the limiting assembly 3 can position the supporting assembly 2.

[0039] By rotating the rubber handle 6, the main bevel gear 7 and the secondary bevel gear 8 in meshing connection are driven to rotate, the adjusting block 10 and the supporting assembly 2 are vertically moved up and down to adjust the compression force through the adjusting screw rod 9, the contraction effect of the supporting assembly 2 improves the smoothness of the operator when pressing down, reduces the resistance feeling when compressing, and the limiting assembly 3 positions the supporting assembly 2, avoids the supporting assembly 2 from being affected by the contraction effect force to continuously press down, and avoids affecting the compression force of the operator manually adjusting, without worrying about the rotation of the rubber handle 6 due to external force impact, which helps to improve the stability of the cable filling rope traction processing.

[0040] In one embodiment, the support assembly 2 includes two fixed rods 21, four first hinge seats 23, four second hinge seats 25, and four composite contraction springs 29. The two fixed rods 21 are disposed inside the fixed seat 1, and two sliders 22 are slidably connected to the surfaces of the two fixed rods 21. The four first hinge seats 23 are respectively disposed at the top ends of the four sliders 22, and hinge rods 24 are hinged to the surfaces of the four first hinge seats 23. The four second hinge seats 25 are respectively hinged to the four hinge rods 24. A fixed frame 26 is connected to the top end of every two second hinge seats 25. A first roller 27 is rotatably connected to the inner side of one of the fixed frames 26. Two connecting rods 28 are connected between the two fixed frames 26. Every two composite contraction springs 29 are respectively sleeved on the surface of each fixed rod 21, and the two ends of the four composite contraction springs 29 are respectively connected to one side of the four sliders 22 and the inner wall of the fixed seat 1.

[0041] First, when it is necessary to manually press down the contact force between the first roller 27 and the second roller 4, the operator holds the rubber handle 6 and rotates it, thereby driving the main bevel gear 7 and the secondary bevel gear 8 to mesh and rotate. Then, through the threaded adjusting screw 9, the adjusting block 10 is driven to descend. At this time, through the elastic contraction action of the corresponding compound contraction spring 29 and the hinge action of the first hinge seat 23 and the second hinge seat 25, the hinge rod 24 tilts under the elastic tension of the compound contraction spring 29. Then, under the connection action of the four symmetrically arranged second hinge seats 25, the first roller 27 will descend vertically. Through the compound contraction spring 29, the first roller 27... It inherently possesses a vertically downward driving force, making it easier for the operator to press down the first roller 27 according to the required clamping force. After adjusting the clamping force, in order to prevent the first roller 27 and the adjusting block 10 from moving upward and resetting, the limiting component 3 is driven to operate. The limiting component 3 moves horizontally to fit against the slider 22, thereby positioning the slider 22 and preventing the first roller 27 from shifting due to continuous strong elastic contraction. This ensures that the clamping force is fixed and has good stability. Similarly, when the clamping force is strong and the first roller 27 needs to move upward, the rubber handle 6 is rotated to move the first roller 27 upward, and then the limiting component 3 positions the slider 22.

[0042] The hinging of the first hinging seat 23 and the second hinging seat 25 facilitates the corresponding inclination of the hinging rod 24 when the first roller body 27 is subjected to the downward pressing force, the rotation of the rubber handle 6 facilitates the rotation of the meshed main bevel gear 7 and the auxiliary bevel gear 8, the vertical up-and-down movement of the adjusting block 10 and the first roller body 27 by the adjusting screw rod 9 facilitates the adjustment of the pressing force, and the first roller body 27 itself has the downward pressing force due to the contraction force of the composite contraction spring 29, thereby improving the smoothness of the operator when pressing down and reducing the resistance when pressing; the limiting assembly 3 facilitates the positioning of the sliding block 22, avoids the influence of the continuous downward pressing of the first roller body 27 due to the contraction force on the manually adjusted pressing force of the operator, and avoids the rotation of the rubber handle 6 due to the external force collision, thereby improving the stability of the traction processing of the cable filling rope.

[0043] In one embodiment, for the above-mentioned fixed seat 1, the surface of the fixed seat 1 and the inner side of the other fixed frame 26 are connected with a second driving source 12, and the two power output ends of the second driving source 12 are connected with the surface of the first roller body 27 and the surface of the second roller body 4, thereby facilitating the rotation of the first roller body 27 and the second roller body 4 to convey the cable filling rope.

[0044] In one embodiment, for the above-mentioned adjusting block 10, one side of the adjusting block 10 is rotationally connected with the surface of the first roller body 27, and the first roller body 27 is located directly above the second roller body 4, thereby avoiding the deviation of the conveying force of the cable filling rope by the first roller body 27 and the second roller body 4.

[0045] In one embodiment, for the above-mentioned limiting assembly 3, the limiting assembly 3 comprises a first driving source 31, the first driving source 31 is arranged on the inner side of the fixed seat 1, the power output ends of the first driving source 31 at both ends are power-connected with connecting lead screws 32, and the surfaces of the two connecting lead screws 32 are threadedly connected with connecting blocks 33, thereby facilitating the positioning of the sliding block 22 and avoiding the change of the set pressing force.

[0046] In one embodiment, for the above-mentioned connecting lead screw 32, the thread directions of the two connecting lead screws 32 are opposite, the surface of each connecting block 33 is respectively fitted with the surface of each two sliding blocks 22, and the surface of the sliding block 22 and the surface of the connecting block 33 are slidably fitted with the inner side of the fixed seat 1, thereby improving the stability of the horizontal movement of the connecting block 33 and the stability of the positioning of the sliding block 22.

[0047] In one embodiment, for the aforementioned adjusting screw 9, the bottom end of the adjusting screw 9 is rotatably connected to the top end of the fixed seat 1 via a bearing, and the other side of the adjusting block 10 is slidably attached to the inner wall of the fixed frame 5, thereby improving the stability when the adjusting block 10 drives the first roller 27 to press downward.

[0048] In summary, using the above-mentioned technical solution of this utility model, when it is necessary to manually press down the contact force between the first roller 27 and the second roller 4, the operator holds the rubber handle 6 and rotates the rubber handle 6, thereby driving the main bevel gear 7 and the secondary bevel gear 8 to mesh and rotate. Then, through the threaded adjustment screw 9, the adjustment block 10 is driven to descend. At this time, through the elastic contraction action of the corresponding composite contraction spring 29 and the hinge action of the first hinge seat 23 and the second hinge seat 25, the hinge rod 24 tilts under the elastic tension of the composite contraction spring 29. Then, under the connection action of the four symmetrically arranged second hinge seats 25, the first roller 27 will be driven to descend vertically. Through the composite contraction spring 29, the first roller 27 itself has a vertically downward driving force. The operator adjusts the pressing force according to the required adjustment. When pressing down the first roller 27, it will be easier. After adjusting the clamping force, in order to prevent the first roller 27 and the adjusting block 10 from moving upward and resetting, the first drive source 31 is driven to operate. The first drive source 31 drives the two connecting screws 32 with opposite thread directions to rotate, which in turn drives the two connecting blocks 33 to move towards each other. At this time, the connecting blocks 33 need to be moved to fit against the slider 22, so as to position the slider 22 and prevent the first roller 27 from being displaced due to the strong elastic contraction of the composite contraction spring 29. At the same time, it also prevents the rubber handle 6 from rotating arbitrarily, so that the clamping force is fixed and has good stability. Similarly, when the clamping force is strong and the first roller 27 needs to be moved upward, the same operation is performed to rotate the rubber handle 6 to move the first roller 27 upward, and then the slider 22 is positioned by the connecting block 33.

[0049] Through the technical scheme, 1, through the hinging action of the first hinging seat 23 and the second hinging seat 25, the hinging rod 24 is inclined correspondingly when the first roller body 27 is subjected to the downward pressing force, the rubber handle 6 is rotated to drive the main bevel gear 7 and the auxiliary bevel gear 8 connected in engagement to rotate, the adjusting screw 9 is driven to drive the adjusting block 10 and the first roller body 27 to move vertically up and down to adjust the pressing force, and the first roller body 27 has the downward pressing force by the contraction force of the composite contraction spring 29, thereby improving the smoothness of the operator when pressing down and reducing the resistance feeling when pressing; 2, the connecting block 33 is driven to move towards each other through the connecting screw 32, the sliding block 22 is positioned through the abutment of the connecting block 33 and the sliding block 22, the pressing force of the operator is not affected by the continuous downward pressing of the first roller body 27 due to the contraction force, the rubber handle 6 is not rotated due to the external force collision, and the stability of the cable filling rope in the traction process is improved.
