[0024] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
[0025] like Figures 1 to 7 As shown, a safety device for an electric fabric cutter includes an upper locking body 1 and a lower locking body 2. The upper locking body 1 and the lower locking body 2 are connected by a rotating shaft 3. Specifically, the upper locking body 1 has mounting grooves 4 at both ends of its side wall, and the lower locking body 2 has a corresponding connecting block 5. The connecting block 5 is inserted into the mounting groove 4 and connected by the rotating shaft 3.
[0026] An installation cavity 6 and a blade protection cavity 7 are formed between the upper locking body 1 and the lower locking body 2. The blade protection cavity 7 is located on one side of the upper locking body 1 and the lower locking body 2. The blade protection cavity 7 can completely cover the blade 8 of the electric fabric cutter. A fingerprint module 9, a controller 10, an electromagnetic lock core 11, a latch 12 and a battery 13 are installed in the installation cavity 6. The controller 10 is electrically connected to the fingerprint module 9 and the electromagnetic lock core 11. The battery 13 supplies power to the fingerprint module 9, the controller 10 and the electromagnetic lock core 11.
[0027] The fingerprint module 9 is used for fingerprint information collection, and its top surface is the collection surface 901, which is exposed on the surface of the lock body 1; the controller 10 has a built-in memory (not shown in the figure), which is used to store the fingerprint information obtained by the fingerprint module 9.
[0028] The electromagnetic lock core 11 is disposed on the inner wall of the upper lock body 1, and the latch 12 is disposed on the inner wall of the lower lock body 2. A first compression spring 14 is installed between the upper lock body 1 and the lower lock body 2. Specifically, a spring mounting hole is provided in the mounting cavity 6 corresponding to the mounting groove 4. The spring mounting hole is a blind hole, and the first compression spring 14 is installed in the spring mounting hole.
[0029] The electromagnetic lock cylinder 11 includes a lock housing 111, a coil 112, a movable lock cylinder 113, and a second spring 114. The coil 112 is installed inside the lock housing 111. The movable lock cylinder 113 is movably fitted at the end of the lock housing 111, with its rear end opposite to the coil 112 and its front end having a latch 115. The second spring 114 is fitted onto the movable lock cylinder 113, and a limiting ring 116 is provided at the end of the movable lock cylinder 113 to limit the movement of the second spring 114. The top surface of the latch 115 is a downward-sloping surface. The latch 12 has a lock hole 121, and the latch 115 extends into or retracts from the lock hole 121 to lock or unlock the upper lock body 1 and the lower lock body 2.
[0030] The working principle of this utility model:
[0031] The fingerprint module 9 acquires the fingerprint information of authorized personnel through the collection surface. The controller 10 compares the fingerprint information with the fingerprint information stored in the memory. If they match, the controller 10 controls the electromagnetic lock cylinder 11 to be energized through the relay. After the coil 112 is energized, it generates a magnetic field, which pulls the movable lock cylinder 113 into the lock housing 111, causing the bolt 115 to exit from the lock hole 121. At this time, the first compression spring 14 installed in the upper lock body 1 pushes the lower lock body 2 to rotate around the rotating shaft 3, thereby opening a gap in the blade protection cavity 7, and the safety device can be removed from the blade 8 of the electric fabric cutter.
[0032] When installing this safety device, simply insert the blade 8 of the electric fabric cutter into the blade protection cavity 7, press the upper locking body 1 and the lower locking body 2, so that the latch 12 gradually approaches the latch tongue 115, and the bottom end of the latch 12 contacts the top surface of the latch tongue 115. Since the top surface is a slope, as the latch 12 is continuously squeezed, the latch tongue 115 is forced to move backward, and the second spring 114 is compressed. When the latch tongue 115 corresponds to the lock hole 121, under the action of the second spring 114, the latch tongue 115 is pushed into the lock hole 121, thereby completing the locking of the upper locking body 1 and the lower locking body 2, and thus completely enclosing and locking the blade 8 of the electric fabric cutter in the blade protection cavity 7.
[0033] The blade protection cavity of this utility model can completely seal and lock the blade, thereby avoiding safety accidents such as cuts. The fingerprint lock combined with the opening and closing structure makes opening and closing very convenient and easy to inspect and maintain. It is especially suitable for high-frequency, multi-person collaborative clothing processing or industrial cutting scenarios.
