Abstract

This utility model discloses a wire cutting device for fingerprint lock assembly, belonging to the field of fingerprint lock assembly technology. It includes a fixing rod with a marking component at one end and a length-fixing component inside. The device uses the length-fixing component to move a side rod towards the periphery of a cavity. This movement causes a T-shaped rod and a winding tape to move away from the positioning groove and cavity, respectively. The winding tape also rotates the winding shaft. One end of the connecting wire is then placed against the side wall of the side rod, and the connecting wire is moved to adhere to the upper surface of the winding tape. The size of the connecting wire can be determined by the scale lines on the winding tape. Once the connecting wire reaches the required length, the side rod is stopped, and a finger is pressed onto the connecting wire at the corresponding length scale line position. This facilitates the length-fixing operation of the wire, thereby enabling the length-fixed cutting operation of the wire.

Description

Technical Field

[0001] This utility model belongs to the field of fingerprint lock assembly technology, specifically relating to a wire cutting device for fingerprint lock assembly. Background Technology

[0002] A fingerprint lock is an intelligent lock that uses fingerprints as its identification medium. It represents the perfect fusion of computer information technology, electronic technology, mechanical technology, and modern hardware craftsmanship. A fingerprint lock generally consists of two parts: electronic identification and control, and a mechanical linkage system.

[0003] Existing wire cutting tools make it difficult for workers to determine the size of the cut wires when using a cutter, which in turn affects the wiring connection effect in fingerprint lock assembly. Utility Model Content

[0004] To address the problems mentioned in the background section, this invention provides a wire cutting device for fingerprint lock assembly, featuring fixed-length cutting and fixed-point marking.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a wire cutting device for fingerprint lock assembly, comprising a fixed rod, a marking component at one end of the fixed rod, a length-fixing component inside the fixed rod, a movable rod rotatably connected to the other end of the fixed rod, a cutter fixedly connected to the side of the movable rod and the fixed rod that are close to each other, and a peeling mechanism provided between the movable rod and the fixed rod and on the side of the cutter. The fixed-length component includes a cavity, and a take-up belt is disposed inside the cavity. The side wall of the take-up belt is provided with scale lines.

[0006] Preferably, a take-up shaft is rotatably connected inside the cavity and at one end of the take-up belt, and a limit member is provided between the take-up belt and the fixing rod.

[0007] Preferably, the limiting member includes a side rod, the side wall of which is provided with a positioning groove, and a T-shaped rod is fixedly connected to the side wall of the fixing rod and located inside the positioning groove.

[0008] Preferably, magnetic sheets are fixedly connected to the sides of the T-shaped rod and the positioning groove that are close to each other.

[0009] Preferably, the marking component includes a connecting block, and a placement tube is fixedly connected to the side wall of the connecting block, with a marking pen inserted inside the placement tube.

[0010] Preferably, a threaded cylinder is fixedly connected to the outer wall of the placement cylinder, and a rotating screw is threadedly connected to the inside of the threaded cylinder.

[0011] Preferably, a rubber pad is fixedly connected to the end of the rotating screw near the marker pen.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model is equipped with a length-fixing component. The side rod moves to the periphery of the cavity. The movement of the side rod causes the T-shaped rod and the winding tape to move away from the positioning groove and the cavity, respectively. The movement of the winding tape causes the winding shaft to rotate. Then, one end of the connecting line is attached to the side wall of the side rod, and the connecting line is moved to be attached to the upper surface of the winding tape. At the same time, the size of the connecting line attached to the winding tape can be judged by the scale lines on the winding tape. When the connecting line reaches the required length, the side rod is stopped, and the finger is pressed on the connecting line at the corresponding length scale line position, which facilitates the length-fixing operation of the line, and thus facilitates the length-fixed cutting operation of the line.

[0013] 2. This utility model features a marking component. A marking pen is placed inside the placement cylinder, and then a rotating screw is rotated to move it along the threaded cylinder. The rotating screw causes a rubber pad to rotate, pushing the marking pen along the placement cylinder. Once the marking pen is in contact with the inner wall of the placement cylinder, the rotating screw is stopped to secure the marking pen. When using a winding tape to cut the connecting line to a fixed length, the corresponding length position on the connecting line is pressed onto the marking pen, facilitating the fixed-length marking operation. The connecting line is then placed between the movable rod and the fixed rod, with the marking point positioned between the two cutters, facilitating the marking operation and subsequently the fixed-length cutting operation.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0017] Please see Figure 1-4 The present invention provides the following technical solution: a wire cutting device for fingerprint lock assembly, including a fixed rod 3, a marking component 6 is provided at one end of the fixed rod 3, a fixed length component 5 is provided inside the fixed rod 3, a movable rod 1 is rotatably connected to the other end of the fixed rod 3, a cutter 4 is fixedly connected to the side of the movable rod 1 and the fixed rod 3 that are close to each other, and a peeling mechanism 2 is provided between the movable rod 1 and the fixed rod 3 and on the side of the cutter 4; The fixed-length component 5 includes a cavity 51, inside which a take-up belt 52 is disposed, and scale lines are disposed on the side wall of the take-up belt 52.

[0018] Specifically, a take-up shaft 53 is rotatably connected inside the cavity 51 and at one end of the take-up belt 52, and a limit member 54 is provided between the take-up belt 52 and the fixing rod 3. By adopting the above technical solution, when the take-up belt 52 is not needed, the take-up shaft 53 is rotated, and the take-up shaft 53 rotates to drive the take-up belt 52 to be wound into the cavity 51. The end of the take-up belt 52 is limited by the limiting member 54, which makes it easy to store and place the take-up belt 52.

[0019] Specifically, the limiting member 54 includes a side rod 541, a positioning groove 543 is provided on the side wall of the side rod 541, and a T-shaped rod 542 is fixedly connected to the side wall of the fixing rod 3 and located inside the positioning groove 543. By adopting the above technical solution, the winding tape 52 moves, causing the side rod 541 to move, and the positioning groove 543 moves accordingly. When the positioning groove 543 moves to fit the outer periphery of the T-shaped rod 542, the side rod 541 is blocked and stops moving, thereby preventing the winding tape 52 from continuing to move, which makes it easier to take the winding tape 52 out for use later.

[0020] Specifically, magnetic sheets are fixedly connected to the sides of the T-shaped rod 542 and the positioning groove 543 that are close to each other. By adopting the above technical solution, after the positioning groove 543 moves to fit the periphery of the T-shaped rod 542, the two magnetic pieces attract and fix each other, ensuring the stability of the insertion of the side rod 541 and the T-shaped rod 542.

[0021] In this embodiment, during the fingerprint lock assembly process, when it is necessary to cut the connecting wires, first move the side rod 541 to the periphery of the cavity 51. The movement of the side rod 541 causes the T-shaped rod 542 and the winding tape 52 to move away from the positioning groove 543 and the cavity 51, respectively. The movement of the winding tape 52 causes the winding shaft 53 to rotate. Then, place one end of the connecting wire against the side wall of the side rod 541 and move the connecting wire against the upper surface of the winding tape 52. At the same time, the size of the connecting wire against the winding tape 52 can be judged by the scale lines on the winding tape 52. When the connecting wire reaches the required length, stop moving the side rod 541 and press the corresponding finger. The connecting line is placed between the movable rod 1 and the fixed rod 3 at the length scale line position, and the pressing position of the connecting line is between the two cutters 4. Then the movable rod 1 is pressed down, and the movable rod 1 moves down, causing the upper cutter 4 to move down. With the help of the lower cutter 4, the connecting line can be cut. When it is necessary to peel off the outer skin of the cut connecting line, the cut connecting line is placed between the movable rod 1 and the fixed rod 3, and then the peeling mechanism 2 is used to peel off the connecting line. Then the cut and peeled connecting line is used to connect the components of the fingerprint lock, which facilitates the assembly of the fingerprint lock. Example 2

[0022] The difference between this embodiment and Embodiment 1 is that the marking component 6 includes a connecting block 66, a placement cylinder 63 is fixedly connected to the side wall of the connecting block 66, and a marking pen 65 is inserted into the interior of the placement cylinder 63. Specifically, a threaded cylinder 62 is fixedly connected to the outer wall of the placement cylinder 63, and a rotating screw 61 is threadedly connected to the inside of the threaded cylinder 62. By adopting the above technical solution, the rotating screw 61 is rotated to move along the threaded cylinder 62. The rotating screw 61 moves and pushes the marking pen 65 along the placement cylinder 63. When the marking pen 65 moves and fits against the inner wall of the placement cylinder 63, the rotating screw 61 is stopped to facilitate the clamping and fixing of the marking pen 65 and ensure the stability of the placement of the marking pen 65.

[0023] Specifically, a rubber pad 64 is fixedly connected to one end of the rotating screw 61 near the marker pen 65. By adopting the above technical solution, the rotating screw 61 rotates and moves, causing the rubber pad 64 to move and fit against the side wall of the marker pen 65. Under the action of the rubber pad 64, friction between the rotating screw 61 and the marker pen 65 can be avoided, thereby preventing the marker pen 65 from wearing out.

[0024] In this embodiment, the marking pen 65 is placed inside the placement cylinder 63, and then the rotating screw 61 is rotated to move along the threaded cylinder 62. The rotation of the rotating screw 61 causes the rubber pad 64 to rotate, and the rubber pad 64 pushes the marking pen 65 along the placement cylinder 63. When the marking pen 65 moves to fit against the inner wall of the placement cylinder 63, the rotating screw 61 is stopped to secure the marking pen 65. When the winding tape 52 is used to perform a fixed-length operation on the connecting line, the corresponding length position on the connecting line is pressed onto the marking pen 65 to facilitate the fixed-length marking operation on the connecting line. Then the connecting line is placed between the movable rod 1 and the fixed rod 3, so that the marking point is located between the two cutters 4 to facilitate the marking operation on the connecting line, and thus facilitate the fixed-length cutting operation on the connecting line.

[0025] The structure and principle of the peeling mechanism 2, which consists of a notch, a second through hole, a storage groove, a lifting hole, a lifting rod, a peeling blade, a limiting rod, and a limiting hole, have been disclosed in a line cutting tool disclosed in Chinese patent application number 202222426847.9. Its working principle is as follows: a notch is provided above the fixed rod 3; a storage groove is provided on the side wall of the movable rod 1 at the position corresponding to the notch; a lifting hole is provided on the side wall of the storage groove; a lifting rod is threadedly connected inside the lifting hole; and a peeling blade is slidably connected inside the storage groove. The peeling blade is close to... Limiting rods are connected to both sides of one end of the storage slot. Limiting holes are opened on the side wall of the storage slot at the positions corresponding to the limiting rods. In use, the line is placed on the notch and the movable rod 1 is pressed down. Then, the lifting rod is rotated. The lifting rod controls the stripper to move down through the thread in the lifting hole. The contact position between the stripper and the lifting rod is a rotatable connection to prevent the stripper from rotating. The limiting holes in the storage slot and the limiting rods on the stripper cooperate to prevent the stripper from rotating. The stripper moves down according to the thickness of the coating to avoid damaging the internal copper core.

[0026] The working principle and usage process of this utility model are as follows: The marking pen 65 is placed inside the placement cylinder 63. Then, the rotating screw 61 is rotated, causing it to move along the threaded cylinder 62. The rotation of the rotating screw 61 drives the rubber pad 64 to rotate, pushing the marking pen 65 along the placement cylinder 63. When the marking pen 65 moves to fit against the inner wall of the placement cylinder 63, the rotating screw 61 is stopped to secure the marking pen 65. During the fingerprint lock assembly process, when it is necessary to cut the connecting wires, the side rod 541 is first moved towards the periphery of the cavity 51. The movement of the side rod 541 causes the T-shaped rod 542 and the winding tape 52 to move away from the positioning groove 543 and the cavity 51, respectively. The movement of the winding tape 52 drives the winding shaft 53 to rotate. Then, one end of the connecting wire is placed against the side wall of the side rod 541, and the connecting wire is moved to fit against the upper surface of the winding tape 52. Simultaneously, the markings on the winding tape 52 can be observed. The size of the connecting line on the reel 52 is determined by the line. When the connecting line reaches the required length, the side rod 541 is stopped, and the corresponding length position on the connecting line is pressed onto the marker pen 65 to facilitate the fixed-length marking operation of the connecting line. Then, the connecting line is placed between the movable rod 1 and the fixed rod 3, so that the marking point is located between the two cutters 4 to facilitate the marking operation of the connecting line, and then to facilitate the fixed-length cutting operation of the connecting line. The movable rod 1 is then pressed down, and the movable rod 1 moves down, driving the upper cutter 4 to move down. With the help of the lower cutter 4, the connecting line can be cut. When it is necessary to peel off the outer skin of the cut connecting line, the cut connecting line is placed between the movable rod 1 and the fixed rod 3, and then the peeling mechanism 2 is used to peel off the connecting line. Then, the cut and peeled connecting line is used to connect the components of the fingerprint lock to facilitate the assembly operation of the fingerprint lock.
