Description

Technical Field

[0001] The present application relates to the technical field of cutting equipment, and in particular to a reciprocating rotary cutting mechanism made of lean pipe. Background Art

[0002] Currently in our daily production or life, in order to make existing objects usable in a specified environment or space, cutting operations are often performed to make them adapt to the specific space.

[0003] When cutting objects, people usually hold the object in one hand and cut the object with scissors in the other hand.

[0004] The above-mentioned existing technical solutions have the following defects: the human hand is too close to the object to be cut, there is a risk of scratching the fingers, and the safety factor is low. Utility Model Content

[0005] In order to improve the safety of operators when cutting objects, the present application provides a reciprocating rotary cutting mechanism made of lean tubes.

[0006] The above technical objectives of this application are achieved through the following technical solutions:

[0007] A reciprocating rotary cutting mechanism made of lean tube includes a base frame on which an input rod is provided. The input rod can slide back and forth along the length direction of the base frame. An output rod is also provided corresponding to the input rod. The output rod is arranged parallel to the input rod and can rotate around the base frame under the drive of the input rod. A linkage structure is provided between the input rod and the output rod. The linkage structure is used to drive the output rod to rotate around the base frame when the input rod is driven to slide along the base frame. A cutting knife is connected to one end of the output rod.

[0008] By adopting the above solution, the input rod is driven to slide along the bottom frame, which can drive the output rod to rotate under the drive of the linkage structure; because a cutting knife is provided, the cutting knife can complete the lifting and cutting operations under the drive of the output rod, so during the cutting process, the operator's hands can be kept away from the cutting position, thereby improving the safety of the operator.

[0009] Furthermore, the linkage structure includes a rope and a fixed pulley, the fixed pulley is fixedly connected to the bottom frame, one end of the rope is fixedly connected to the side wall of the input rod, and the other end of the rope passes through the fixed pulley and is wound around the output rod.

[0010] By adopting the above solution, because a rope is provided to drive the input rod to slide along the bottom frame, the output rod can be driven to rotate under the drive of the rope. Because a fixed pulley is provided, the fixed pulley can tension the rope, making it convenient to transmit the tension on the rope to the output wheel and thereby drive the output wheel to rotate.

[0011] Furthermore, an elastic member is provided at one end of the output rod away from the cutting knife, and both ends of the elastic member are fixedly connected to the bottom frame and the output rod respectively; the elastic member can drive the output rod to rotate under its own elastic action.

[0012] By adopting the above solution, the elastic member can drive the output rod to rotate under the action of its own elasticity, and the rotation of the output rod can drive the cutting knife to cut the object.

[0013] Furthermore, a limiting ring is provided on the bottom frame, and two limiting rings are provided. The two limiting rings are respectively used to limit the sliding amount of the input rod sliding toward both sides along the bottom frame.

[0014] By adopting the above solution, the limiting ring can limit the sliding amount of the input rod, and then the rotation amount of the output rod can be controlled through the rope, thereby controlling the rotation amount of the cutting knife.

[0015] Furthermore, a toggle rod is fixedly connected to the input rod, and the toggle rod is arranged between the two limiting rings. The toggle rod is used to drive the input rod to slide along the bottom frame.

[0016] By adopting the above solution, the setting of the toggle rod facilitates driving the input rod to slide along the bottom frame.

[0017] Furthermore, the input rod is T-shaped as a whole.

[0018] By adopting the above solution, the T-shaped setting makes it easier for people to hold the toggle lever.

[0019] Furthermore, a limiting member is provided on the fixed pulley, and the limiting member is U-shaped as a whole, with both ends of the limiting member fixedly connected to both sides of the fixed pulley respectively, and the limiting member is used to limit the rope passing through the fixed pulley.

[0020] By adopting the above solution, the setting of the limiting member is used to limit the rope passing through the fixed pulley.

[0021] Furthermore, the bottom frame is fixedly connected to a sleeve corresponding to the input rod, and there are at least two sleeves, which are respectively arranged near the two sides of the bottom frame; the input rod is inserted into the two sleeves and is slidingly connected to the two sleeves; each sleeve is provided with a protrusion, and a groove is opened inward on the input rod corresponding to the protrusion, and the groove is plugged into the protrusion.

[0022] By adopting the above solution, the projection is plugged into and matched with the groove, so that when the input rod slides along the sleeve, relative rotation between the input rod and the sleeve is avoided.

[0023] In summary, this application has the following technical effects:

[0024] 1. By setting up this mechanism, the input rod is driven to slide along the bottom frame, which can drive the output rod to rotate under the drive of the linkage structure. Because the cutting knife is set, the cutting knife can complete the knife lifting and cutting operations under the drive of the output rod. Therefore, during the cutting process, the operator's hands can be kept away from the cutting position, achieving the effect of improving the operator's safety.

[0025] 2. By providing an elastic member, the elastic member can drive the output rod to rotate under its own elastic action, and the rotation of the output rod can drive the cutting knife to cut the object;

[0026] 3. By providing a protrusion, the protrusion is plugged into and matched with the groove, so that when the input rod slides along the sleeve, relative rotation between the input rod and the sleeve is avoided. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The present application is further described in detail below with reference to the accompanying drawings.

[0031] Reference Figure 1 , this embodiment provides a reciprocating rotary cutting mechanism made of lean tube, including a base frame 1, an input rod 2, an output rod 3, a linkage structure 4 and a cutting knife 8. One side of the base frame 1 is used to abut against the work; the input rod 2 is arranged on the upper surface of the base frame 1, and the input rod 2 is slidably connected to the base frame 1, and the input rod 2 can slide back and forth along the length direction of the base frame 1; the output rod 3 is arranged on the same side as the input rod 2, the output rod 3 and the input rod 2 are parallel to each other, and the input rod 2 is rotatably connected to the base frame 1; the cutting knife 8 is fixedly connected to one end of the output rod 3; the linkage structure 4 is located between the input rod 2 and the output rod 3, and the linkage structure 4 is used to drive the output rod 3 to rotate when the input rod 2 moves along the length direction of the base frame 1, and the output rod 3 drives the cutting knife 8 to cut the object.

[0032] Reference Figure 1In this embodiment, the base frame 1 is a frame structure composed of several lean tubes, and the overall shape is I-shaped. The output rod 3 is rotatably connected to the base frame 1 as follows: a rotating cylinder 12 is fixedly connected to the base frame 1. In this embodiment, two rotating cylinders 12 are provided, and a distance is left between the two rotating cylinders 12; the output rod 3 is inserted into the rotating cylinder 12, and the output rod 3 is rotatably connected to the rotating cylinder 12.

[0033] Reference Figure 1-Figure 2 The specific way in which the input rod 2 is slidably connected to the bottom frame 1 is as follows: two sleeves 11 are fixedly connected to the bottom frame 1, with a gap left between the two sleeves 11, and the input rod 2 is inserted into the sleeves 11. The two sleeves 11 of the input rod 2 are slidably connected, so that the input rod 2 can slide back and forth along the length direction of the bottom frame 1; the inner wall of each sleeve 11 is fixedly connected with a convex strip 111, and the input rod 2 is provided with an inwardly concave groove corresponding to the convex strip 111, and the groove is plugged into the convex strip 111. When the input rod 2 slides along the sleeve 11, the convex strip 111 and the groove slide relative to each other. This arrangement can prevent the input rod 2 from rotating along the sleeve 11.

[0034] Reference Figure 1 The linkage structure 4 includes a fixed pulley 41 and a rope 42, one end of the rope 42 is fixedly connected to the side wall of the input rod 2 away from the cutting knife 8 and close to the output rod 3, the fixed pulley 41 is fixedly connected to the bottom frame 1, and the other end of the rope 42 passes through the fixed pulley 41 and is sleeved on the output rod 3; the setting of the fixed pulley 41 makes the rope 42 use the fixed pulley 41 as the dividing point, and the rope 42 between the input rod 2 and the fixed pulley 41 and the rope 42 between the output rod 3 and the fixed pulley 41 are perpendicular to each other; when the input rod 2 is driven to slide along the sleeve 11, the other end of the rope 42 passes through the fixed pulley 41 to drive the output rod 3 to rotate around the rotating cylinder 12, thereby controlling the angle between the cutting knife 8 and the working surface.

[0035] Reference Figure 1 An elastic member 5 is provided at the end of the output rod 3 close to the end facing away from the cutting knife 8. One end of the elastic member 5 is fixedly connected to the side wall of the output rod 3, and the other end of the elastic member 5 is fixedly connected to the bottom frame 1. The arrangement of the elastic member 5 enables the elastic member 5 to drive the output rod 3 to rotate under the elastic action of itself in the absence of external force, so that the cutting knife 8 cuts the object. In this embodiment, the elastic member 5 is preferably used as a spring.

[0036] Reference Figure 1 A limiting member 411 is provided on the fixed pulley 41. The limiting member 411 is U-shaped as a whole. The two ends of the limiting member 411 are fixedly connected to the two sides of the fixed pulley 41 respectively. The limiting member 411 is used to limit the rope 42 passed through the fixed pulley 41.

[0037] Reference Figure 1A toggle rod 7 is provided on the input rod 2, and the toggle rod 7 is located between the two sleeves 11. The toggle rod 7 is T-shaped as a whole. The toggle rod 7 is fixedly connected to the input rod 2. The setting of the toggle rod 7 facilitates the sliding of the input rod 2 along the sleeve 11; a limit ring 6 is provided on both sides of the toggle rod 7, and the two limit rings 6 are located on the side where the two sleeves 11 are close to each other; each sleeve 11 is slidably connected to the input rod 2 and is fixedly connected to the bottom frame 1. The limit ring 6 is used to limit the maximum sliding range of the input rod 2 reciprocating along the sleeve 11.

[0038] The specific implementation principle of the reciprocating rotary cutting mechanism made of a lean tube in the embodiment of the present application is as follows: driving the toggle rod 7 to move toward the end away from the cutting knife 8, and the toggle rod 7 drives the input rod 2 to move along the sleeve 11; the input rod 2 drives the rope 42 to move, and the other end of the rope 42 passes around the fixed pulley 41 to drive the output rod 3 to rotate, and the rotation of the output rod 3 drives the cutting knife 8 to be lifted at an angle relative to the working surface; and the rotation of the output rod 3 will drive the elastic member 5 to contract and be wound around the output rod 3; then the object to be cut is placed on the working surface, and the toggle rod 7 is released; the elastic member 5 rebounds under the action of its own elasticity, thereby driving the output rod 3 to rotate, and the output rod 3 drives the cutting knife 8 to rotate in the direction close to the working surface, thereby completing the cutting of the object.

[0039] This specific embodiment is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but as long as they are within the scope of the claims of the present application, they are protected by the patent law.
