Description

Technical Field

[0001] The invention relates to the technical field of cable cutting equipment, and in particular to a suspended electric cable cutting device. Background Art

[0002] During the wiring construction, the cable needs to be cut at a fixed length according to the actual wiring length, and the cable cutting operation needs to be implemented through a cutting device. In order to reduce the labor intensity of workers and improve the efficiency of cable cutting, the cutting device is generally set to be electrically driven.

[0003] The existing wire cutting device is generally provided with a component for intercepting, blocking and limiting the cable during the process of cutting the cable. However, these intercepting and limiting components are mostly arranged at the head end of the wire cutting device, which is far away from the hand holding the main part of the wire cutting device. As a result, the hand cannot directly tighten or open and close the intercepting and limiting components when holding and using the wire cutting device as a whole. The hand needs to be moved to be close to the intercepting and limiting components to implement the operation. The operation is relatively troublesome and inconvenient, which indirectly reduces the efficiency of the wire cutting operation of the wire cutting device.

[0004] In addition, in order to prevent the intercepting and limiting components from shifting and loosening during the cutting operation, the wire cutting device is generally equipped with components for positioning the intercepting and limiting components. However, the tightening and loosening operations of these positioning components require additional manual effort before each cutting operation, which is cumbersome to operate and use, further indirectly reducing the cutting operation efficiency of the wire cutting device. Summary of the invention

[0005] In view of this, the present invention provides a suspended electric cable cutting device to solve the problem that the loosening and tightening operation of the components for positioning the interception and limiting components requires additional manual force before and after each cutting operation, which makes the operation more cumbersome.

[0006] The technical solution proposed by the present invention is: a suspended electric cable cutting device, specifically comprising: an electric push rod; a cutter is threadedly fastened on the first end of the telescopic rod of the electric push rod;

[0007] The top part of the electric push rod is fixedly installed with a track frame, and the track frame as a whole is composed of a ring and two vertical track rods symmetrically welded on the ring, and the cable to be cut is clamped between the two vertical track rods; the top parts of the two vertical track rods are slidably penetrated by an interception rod, and the head end of the interception rod is penetrated by a square positioning hole; a sliding ring is slidably installed on the circumferential shell wall of the electric push rod, and an L-shaped driving rod is welded on the circumferential outer ring of the sliding ring, and a group of connecting rods are rotatably connected between the head end of the L-shaped driving rod and the tail end of the interception rod;

[0008] An L-shaped positioning rod is installed on the outer side of the vertical track rod through a spring push and sliding, and the top part of the L-shaped positioning rod is an oblique section structure. When the intercepting rod slides toward the L-shaped positioning rod, the head end abuts against the inclined surface of the oblique section of the top end of the L-shaped positioning rod, and the oblique section of the top end of the L-shaped positioning rod is plugged and matched with the square positioning hole; a U-shaped connecting piece is welded on the outer side of the bottom end of the vertical track rod, and a shaft sleeve is slidably installed on the U-shaped connecting piece, a trapezoidal driving block is welded on the shaft sleeve, and a pull rod is rotatably connected between the shaft sleeve and the L-shaped positioning rod;

[0009] An annular driving frame is slidably mounted on the sliding ring, and the annular driving frame as a whole is composed of two upper and lower sliding rings and a circle of short sliding shafts welded around the two sliding rings, wherein the circle of short sliding shafts penetrates and slides with the sliding ring; an L-shaped force transmission rod is welded to the circumferential outer ring of the upper slip ring, and when the L-shaped force transmission rod slides toward the trapezoidal driving block, the head end of the L-shaped force transmission rod abuts and contacts with the inclined surface of the trapezoidal driving block; a spring is mounted on the circumferential shell wall of the electric push rod, and the head end of the spring abuts and contacts with the ferrule, and the tail end abuts and contacts with the upper slip ring.

[0010] Furthermore,

[0011] The inner sides of the two vertical track rods are provided with strip-shaped sliding grooves, and the two ends of the cutter are correspondingly slidably matched with the two strip-shaped sliding grooves.

[0012] Furthermore,

[0013] A short connecting shaft is welded between the shaft sleeve and the trapezoidal driving block, the head end of the pull rod is rotatably connected to the tail end of the L-shaped positioning rod, and the tail end is rotatably connected to the short connecting shaft.

[0014] Furthermore,

[0015] The ferrule is sleeve-fitted with the top end portion of the electric push rod and is threadedly fastened on the top end portion of the electric push rod.

[0016] Furthermore,

[0017] Under normal conditions, a distance is maintained between the slip ring and the slip ring on the lower side.

[0018] Furthermore,

[0019] A motor is integrated and installed at the bottom end of the electric push rod, and a handle is threadedly fastened to the bottom of the motor. The handle is funnel-shaped and hollow inside.

[0020] Furthermore,

[0021] A detachable rechargeable battery is installed at the bottom end of the handle.

[0022] Furthermore,

[0023] Two button switches are symmetrically mounted on the circumferential shell wall of the bottom end of the handle, and the two button switches respectively control the forward rotation and reverse rotation of the motor.

[0024] The invention provides a suspended electric cable cutting device, which has the following beneficial effects:

[0025] When the present invention is in use, the annular drive frame is slidably mounted on the electric push rod and is close to the handle, which enables the hand holding the handle to position and operate the device as a whole to directly drive the sliding ring to slide up and down through the annular drive frame to control the insertion and opening and closing of the intercepting rod. Compared with the prior art, the intercepting rod can be opened and closed by moving the hand close to the intercepting rod without additional movement of the hand. The operation is more convenient and helps to indirectly improve the cutting efficiency of the wire cutting device.

[0026] In addition, through the power transmission of the L-shaped force transmission rod and the use of the spring on the L-shaped positioning rod, before each cutting operation, when the annular drive frame slides up and down to drive the intercepting rod to be inserted and opened and closed, the L-shaped positioning rod can be driven to slide up and down to loosen or tighten the intercepting rod. Compared with the existing technology, the need for additional manual insertion and extraction of the L-shaped positioning rod to loosen or tighten the intercepting rod before each cutting operation can be eliminated. The operation is convenient and easy to use, which helps to simplify the operating steps of the wire cutting device and can further indirectly improve the cutting operation efficiency of the wire cutting device.

[0027] In addition, since there is a distance between the lower slip ring and the slip ring and the slip ring is not in direct contact with the slip ring, the annular drive frame does not push the slip ring upward in the initial state of upward sliding. This allows the annular drive frame to first use the L-shaped force transmission rod to push the L-shaped positioning rod to slide downward and release the intercepting rod in the initial state of upward sliding. After the L-shaped positioning rod releases the intercepting rod, the lower slip ring contacts the slip ring and pushes the slip ring upward to drive the intercepting rod to be pulled out. This allows the operation of sliding the L-shaped positioning rod down to release the intercepting rod and the operation of pulling out the intercepting rod to open the feeding port to be performed in sequence, avoiding interference between the two steps, resulting in the intercepting rod being unable to be normally pulled out to open the feeding port, affecting the normal use of the wire cutting device.

[0050] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0051] Please refer to Figures 1 to 8 , an embodiment provided by the present invention:

[0052] The present invention proposes a suspended electric cable cutting device, comprising: an electric push rod 1, a motor 2, a handle 3, a rechargeable battery 4, a button switch 5, an annular drive frame 6, an L-shaped force transmission rod 601, a sliding ring 7, an L-shaped drive rod 701, a connecting rod 702, a track frame 8, an intercepting rod 801, a U-shaped connecting piece 802, a shaft sleeve 803, a trapezoidal drive block 804, an L-shaped positioning rod 9, a pull rod 901, and a cutter 10; the cutter 10 is threadedly fastened to the head end of the telescopic rod of the electric push rod 1; the motor 2 is integrated with the bottom end of the electric push rod 1, and the handle 3 is threadedly fastened to the bottom of the motor 2, and the handle 3 is funnel-shaped and hollow inside;

[0053] Among them, the top part of the electric push rod 1 is fixedly installed with a track frame 8, and the track frame 8 as a whole is composed of a ring and two vertical track rods symmetrically welded on the ring, and the cable to be cut is placed between the two vertical track rods; the top parts of the two vertical track rods are slidably penetrated by an interception rod 801, and the head end of the interception rod 801 is penetrated by a square positioning hole; a sliding ring 7 is slidably installed on the circumferential shell wall of the electric push rod 1, and an L-shaped driving rod 701 is welded to the circumferential outer ring of the sliding ring 7, and a group of connecting rods 702 are rotatably connected between the head end of the L-shaped driving rod 701 and the tail end of the interception rod 801;

[0054] When the motor 2 rotates forward, the telescopic rod of the electric push rod 1 is driven to extend upward and the cutter 10 is driven to slide upward, so as to press and cut the cable stuck between the two vertical rail rods. When the motor 2 rotates reversely, the telescopic rod of the electric push rod 1 is driven to retract and the cutter 10 is driven to slide downward and reset, so as to prepare for the next cutting operation.

[0055] An L-shaped positioning rod 9 is installed on the outer side of a vertical track rod through a spring push and sliding, and the top part of the L-shaped positioning rod 9 is an oblique section structure. When the intercepting rod 801 slides toward the L-shaped positioning rod 9, the head end abuts against the inclined surface of the oblique section of the top end of the L-shaped positioning rod 9, and the oblique section of the top end of the L-shaped positioning rod 9 is plugged into the square positioning hole; a U-shaped connecting piece 802 is welded on the outer side of the bottom end of a vertical track rod, and a shaft sleeve 803 is slidably installed on the U-shaped connecting piece 802, and a trapezoidal driving block 804 is welded on the shaft sleeve 803, and a pull rod 901 is rotatably connected between the shaft sleeve 803 and the L-shaped positioning rod 9;

[0056] An annular driving frame 6 is slidably mounted on the sliding ring 7. The annular driving frame 6 as a whole is composed of two upper and lower sliding rings and a circle of short sliding shafts welded around the two sliding rings, wherein the circle of short sliding shafts penetrates and slides with the sliding ring 7; an L-shaped force transmission rod 601 is welded on the circumferential outer ring of the upper side sliding ring, and when the L-shaped force transmission rod 601 slides toward the trapezoidal driving block 804, the head end of the L-shaped force transmission rod 601 abuts against the inclined surface of the trapezoidal driving block 804; a spring is sleeved on the circumferential shell wall of the electric push rod 1, the head end of the spring abuts against the ferrule, and the tail end abuts against the upper side sliding ring;

[0057] The opening between the top parts of the two vertical track rods is the feeding port; a group of connecting rods 702, intercepting rods 801, L-shaped driving rods 701 and sliding rings 7 are connected together to form a crank slider mechanism, through which the upper and lower sliding sliding rings 7 can push and drive the intercepting rod 801 to slide along the top parts of the two vertical track rods to switch the feeding port. When the intercepting rod 801 is pulled out to open the feeding port, the cable can be clamped and released. When the intercepting rod 801 is inserted and blocked to block the feeding port, it can block and limit the cable during the cutting operation, and the cable is intercepted against it for cutting and cutting by the cutter 10; when the intercepting rod 801 is inserted and blocked to block the feeding port, a hanging groove with a rectangular structure is formed around the intercepting rod 801, the two vertical track rods and the cutter 10, and the wire cutting device as a whole can be hung on the cable for use through this hanging groove;

[0058] When the annular driving frame 6 slides upward, it can drive the sliding ring 7 to compress the spring thereon and slide upward. When the sliding ring 7 slides upward, it pushes and drives the intercepting rod 801 to slide in the direction away from the L-shaped positioning rod 9, and the feeding port is opened. When the annular driving frame 6 is released, the spring on the electric push rod 1 can automatically rebound and drive the annular driving frame 6 and the sliding ring 7 to slide downward and reset, and drive and control the intercepting rod 801 to slide and reset toward the L-shaped positioning rod 9, inserting and blocking the feeding port;

[0059] It is worth noting that: when the annular driving frame 6 and the sliding ring 7 slide downward to the lowest end, driving the intercepting rod 801 to slide to the maximum stroke in the direction away from the L-shaped positioning rod 9, the intercepting rod 801 does not separate from the vertical track rod near the connecting rod 702, and the head end of the intercepting rod 801 is retained in the space between the two vertical track rods; two limit blocks are symmetrically welded on the tail end of the intercepting rod 801, and when the intercepting rod 801 slides toward the L-shaped positioning rod 9, the two limit blocks abut against and contact with the vertical track rod near the connecting rod 702;

[0060] The annular drive frame 6 is slidably mounted on the electric push rod 1 and is close to the handle 3, so that the hand holding the handle 3 to position and operate the device as a whole can directly drive the sliding ring 7 to slide up and down through the annular drive frame 6 to control the insertion and opening and closing of the interception rod 801. Compared with the prior art, the interception rod 801 can be opened and closed without moving the hand additionally, and the hand can be moved close to the interception rod 801. The operation is more convenient, which helps to indirectly improve the cutting efficiency of the wire cutting device.

[0061] When the L-shaped positioning rod 9 is pushed and driven to slide downward, the intercepting rod 801 will compress the spring on it and slide downward to the empty position. When the L-shaped positioning rod 9 is pushed and driven to slide downward to the empty position, the intercepting rod 801 will continue to slide toward the L-shaped positioning rod 9. During this process, when the square positioning hole follows the sliding of the intercepting rod 801 and coincides with the L-shaped positioning rod 9, the spring on the L-shaped positioning rod 9 will automatically rebound and push to drive the L-shaped positioning rod 9 to slide upward and plug and cooperate with the square positioning hole. The L-shaped positioning rod 9 can insert and position the intercepting rod 801 in a state of plugging and cooperating with the top parts of the two vertical track rods to implement the use state of blocking the feeding port, so as to avoid the intercepting rod 801 from loosening and shifting during the cutting operation to open the feeding port, thereby losing the blocking and intercepting effect on the cable and affecting the normal and effective cutting operation.

[0062] The L-shaped positioning rod 9, the pull rod 901 and the shaft sleeve 803 are connected together to form a crank slider mechanism. Through this mechanism, the shaft sleeve 803 can be reciprocated along the U-shaped connecting piece 802 to drive the L-shaped positioning rod 9 to slide up and down and to be pulled out or plugged into the square positioning hole to tighten the intercepting rod 801. Through the inclined guide principle of the trapezoidal driving block 804, the L-shaped force transmission rod 601 can push and drive the trapezoidal driving block 804 and the shaft sleeve 803 to slide toward the tail end of the U-shaped connecting piece 802 when sliding upward with the annular driving frame 6, so as to control the compression of the L-shaped positioning rod 9. The spring on it slides downward and is pulled out to release the intercepting rod 801. When the annular driving frame 6 is driven to slide downward and reset, and the L-shaped force transmission rod 601 is separated from the trapezoidal driving block 804, the spring on the L-shaped positioning rod 9 automatically rebounds to drive the L-shaped positioning rod 9 to slide upward and reset and plug and match with the square positioning hole to implement plug-in positioning of the intercepting rod 801. When the L-shaped positioning rod 9 is driven to slide upward and reset, it can drive the control shaft sleeve 803 and the trapezoidal driving block 804 to slide back to prepare for the L-shaped force transmission rod 601 to slide upward again and drive the L-shaped positioning rod 9 to slide down and be pulled out;

[0063] Before each cutting operation, the interception rod 801 needs to be pulled out to open the feeding port, and the cable needs to be clamped and placed between the two vertical track rods, and the interception rod 801 needs to be inserted again to block the feeding port, and the cable needs to be blocked and limited;

[0064] Through the power transmission of the L-shaped force transmission rod 601 and in conjunction with the spring on the L-shaped positioning rod 9, before each cutting operation, when the annular driving frame 6 slides up and down to drive the intercepting rod 801 to be inserted and opened and closed, the L-shaped positioning rod 9 can be driven to slide up and down to loosen or tighten the intercepting rod 801. Compared with the prior art, the need for additional manual insertion and extraction of the L-shaped positioning rod 9 to loosen or tighten the intercepting rod 801 before each cutting operation can be eliminated. The operation is convenient and easy to use, which helps to simplify the operating steps of the wire cutting device and can further indirectly improve the cutting efficiency of the wire cutting device.

[0065] Preferably,

[0066] The inner sides of the two vertical track rods are provided with strip-shaped slide grooves, and the two ends of the cutter 10 are correspondingly slidably matched with the two strip-shaped slide grooves.

[0067] Preferably,

[0068] A short connecting shaft is welded between the shaft sleeve 803 and the trapezoidal driving block 804 . The head end of the pull rod 901 is rotatably connected to the tail end of the L-shaped positioning rod 9 , and the tail end is rotatably connected to the short connecting shaft.

[0069] Preferably,

[0070] The ferrule is inserted and matched with the top end portion of the electric push rod 1 and is threadedly fastened to the top end portion of the electric push rod 1 .

[0071] Preferably,

[0072] Under normal conditions, there is a gap between the lower slip ring and the slip ring 7;

[0073] The annular driving frame 6 pushes the sliding ring 7 upward by pushing the lower side sliding ring, and then the annular driving frame 6 drives the sliding ring 7 to slide upward when the lower side sliding ring slides upward and contacts the sliding ring 7. Since there is a gap between the lower side sliding ring and the sliding ring 7 and the sliding ring 7 is not directly contacted, the annular driving frame 6 does not push the sliding ring 7 upward in the initial state of sliding upward, which makes the annular driving frame 6 push the L-shaped force transmission rod 601 to drive the L-shaped positioning rod in the initial state of sliding upward. 9 slides downward to release the intercepting rod 801, and when the L-shaped positioning rod 9 releases the intercepting rod 801, the lower side slip ring contacts the slip ring 7 and pushes the slip ring 7 upward to drive the intercepting rod 801 to be pulled out. This allows the operation of the L-shaped positioning rod 9 sliding down to release the intercepting rod 801 and the operation of pulling out the intercepting rod 801 to open the feeding port to be performed in sequence, avoiding interference between the two steps, resulting in the intercepting rod 801 being unable to be normally pulled out to open the feeding port, affecting the normal use of the wire cutting device.

[0074] Preferably,

[0075] A detachable rechargeable battery 4 is installed at the bottom end of the handle 3.

[0076] Preferably,

[0077] Two button switches 5 are symmetrically mounted on the circumferential shell wall at the bottom of the handle 3. The two button switches 5 control the forward and reverse rotation of the motor 2 respectively. Electrical components matching the two button switches 5 for controlling the forward and reverse rotation of the motor 2 are mounted inside the handle 3.

[0078] The motor 2 is controlled by two button switches 5 to implement forward and reverse rotation.

[0079] Working principle: The cable to be cut is placed between two vertical rail rods. The motor 2 is controlled by two button switches 5 to rotate forward and reverse. When the motor 2 rotates forward, the telescopic rod of the electric push rod 1 is driven to extend upward and the cutter 10 is driven to slide upward, so as to press and cut the cable stuck between the two vertical rail rods. When the motor 2 rotates reversely, the telescopic rod of the electric push rod 1 is driven to shrink and the cutter 10 is driven to slide downward and reset, so as to prepare for the next cutting operation.

[0080] When the interception rod 801 is pulled out to open the feeding port, the cable can be clamped and released. When the interception rod 801 is inserted to block the feeding port, it can block and limit the cable during the cutting operation, and the cable is intercepted against it for cutting and cutting by the cutter 10.

[0081] Through the power transmission of the L-shaped force transmission rod 601 and in conjunction with the spring on the L-shaped positioning rod 9, before each cutting operation, when the annular driving frame 6 slides up and down to drive the intercepting rod 801 to be inserted and opened and closed, the L-shaped positioning rod 9 can be driven to slide up and down to tighten the intercepting rod 801.
