Detailed Implementation
[0026] 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.
[0027] Please see Figure 1-2 This utility model provides a technical solution: an electromagnetic lock safety switch with a lock head that can be rotated and adjusted at multiple angles, including a housing 1, a cover plate 2 provided at the open end of the housing 1, an insertion hole 3 provided at the middle of the top of the housing 1, a locking component 4 inserted into the inner cavity of the insertion hole 3, a limiting component 5 provided at the top of the inner cavity of the housing 1 for limiting the bottom end of the locking component 4; a locking component 6 inserted into the inner cavity of the limiting component 5, and the top end of the locking component 6 extending into the inner cavity of the locking component 4, a pushing component 7 connected to the bottom end of the locking component 6, and the two side walls of the pushing component 7 connected to the two side walls of the inner cavity of the housing 1, and a circuit board 8 provided on one side of the bottom of the inner cavity of the housing 1;
[0028] The outer casing 1, together with the cover plate 2, can be used to install and protect the limiting component 5, the pushing component 7, and the circuit board 8 installed inside. It can also be used to insert and install the locking component 4 through the insertion hole 3. The limiting component 5 can lock and limit the locking component 4, allowing the locking component 4 to rotate flexibly within the limiting component 5. This allows the orientation of the locking component 4 to be adjusted to facilitate the insertion of external plugs. The circuit board 8 can control the operation of the pushing component 7, which can drive the locking component 6 to move upward, thereby locking and limiting the external plug inserted into the locking component 4 to prevent the external plug from falling out of the locking component 4. Furthermore, by adjusting the rotation of the locking component 4, the device can easily lock and limit external plugs from any angle, thereby improving the convenience and range of use of the electromagnetic lock safety switch.
[0029] See Figures 2-4The engaging component 4 includes a lock head 41, with a locking hole 42 on one side wall of the lock head 41. A guide tube 43 is integrally formed at the bottom end of the lock head 41, extending into the inner cavity of the limiting component 5. An annular groove 44 for engaging the limiting component 5 is formed on the outer wall of the guide tube 43. The limiting component 5 includes a retaining ring 51 disposed at the top of the inner cavity of the outer shell 1. A first internal thread groove 52 is formed on both sides of the surface of the retaining ring 51, and the middle of the two first internal thread grooves 52 communicates with the inner cavity of the retaining ring 51. A limiting screw 53 is rotatably installed in the inner cavity of the two first internal thread grooves 52, and one side of the limiting screw 53 is inserted into the inner cavity of the annular groove 44. Mounting plates 54 are fixedly disposed at the top of both side walls of the retaining ring 51. Mounting screws 55 are inserted into the middle of the bottom surface of the two mounting plates 54, and the top of the mounting screws 55 is connected to the top surface of the inner cavity of the outer shell 1.
[0030] The locking head 41 in the locking assembly 4 allows for easy insertion of an external plug through the locking hole 42, and can also be inserted into the inner cavity of the retaining ring 51 in the limiting assembly 5 through the guide tube 43. By rotating the two limiting screws 53 into the inner cavities of the two first internal thread grooves 52, the two limiting screws 53 can be locked onto both sides of the annular groove 44 on the guide tube 43, thereby achieving the purpose of locking and limiting the guide tube 43 to prevent it from falling out of the inner cavity of the retaining ring 51, while not affecting the rotation of the locking head 41. This allows for flexible adjustment of the orientation of the locking head 41, making it convenient for the locking head 41 to lock and limit external plugs coming from any angle, improving the convenience and range of use of the electromagnetic lock safety switch. Through the mounting plate 54 and mounting screws 55, the retaining ring 51 can be stably and firmly fixed to the top surface of the inner cavity of the outer shell 1, thereby improving the stability of the retaining ring 51 and the locking head 41 in use.
[0031] See Figure 2 , Figure 6 The locking assembly 6 includes a locking pin 61. The bottom end of the locking pin 61 has a second internal thread groove 62 for connecting to the pushing assembly 7. Multiple rotating rods 63 are arranged around the outer wall of the locking pin 61 near the bottom end. The pushing assembly 7 includes a push plate 71. A hollow tube 72 is provided in the middle of the top surface of the push plate 71. A top pin 73 is inserted into the inner cavity of the hollow tube 72. The bottom end of the top pin 73 is connected to the bottom end of the inner cavity of the hollow tube 72 by a spring. A connecting stud 74 for connecting to the second internal thread groove 62 is connected to the top end of the top pin 73. Electric push rods 75 are provided on both sides of the top surface of the push plate 71. A fixing seat 76 is provided in the middle of the two electric push rods 75. The two fixing seats 76 are respectively connected to the two side walls of the inner cavity of the outer shell 1. A lever 77 is provided on the surface of the top pin 73 near the top end.
[0032] By pushing the fixing seat 76 in component 7, it can be fixed to the inner wall of the outer shell 1 and the electric push rod 75 can be installed. When it is necessary to lock and limit the external plug inserted into the lock head 41, the electric push rod 75 can drive the hollow tube 72 to move upward via the push plate 71, thereby synchronously driving the top column 73 to move upward under the elastic force of the spring. Since the bottom end of the locking column 61 is rotatably connected to the connecting stud 74 on the top column 73 via the second internal thread groove 62, when the top column 73 moves upward, it will synchronously drive the locking column 61 to move upward, thus enabling... The locking pin 61 locks and limits the external plug inserted into the lock head 41, preventing the external plug from falling off the lock head 41. When it is necessary to release the external plug, the electric push rod 75 moves downward, which in turn moves the locking pin 61 downward, thus releasing the locking limit of the external plug. When the equipment is powered off or damaged, the user can remove the cover plate 2 and then drive the top pin 73 downward through the lever 77, which will also move the locking pin 61 downward, thus releasing the locking limit of the external plug.
[0033] See Figure 1 , Figure 2 A junction box 9 is provided on one side of the outer wall of the outer casing 1, and the circuit board 8 is electrically connected to the junction box 9 and the push assembly 7, which allows users to easily connect an external power supply or control equipment, thereby enabling users to easily control the operation of the equipment.
[0034] See Figure 1 , Figure 2 Both sides of the outer casing 1 are provided with fixing plates 10, and each fixing plate 10 has fixing holes on its surface. Through the fixing plates 10 and fixing holes, users can easily fix the outer casing 1 in a designated position, thereby improving the stability of the outer casing 1 in use.
[0035] During operation, the outer casing 1, in conjunction with the cover plate 2, can be used to install and protect the limiting component 5, the pushing component 7, and the circuit board 8 installed within it. It can also be used to insert and install the engaging component 4 through the insertion hole 3. The limiting component 5 can engage and limit the engaging component 4, allowing it to rotate flexibly within the limiting component 5 and adjust its orientation to facilitate the insertion of external plugs. The circuit board 8 controls the operation of the pushing component 7, which in turn moves the locking component 6 upwards, locking and limiting the external plug inserted into the engaging component 4 to prevent it from falling out. Furthermore, by adjusting the rotation of the engaging component 4, the device can easily lock and limit external plugs from any angle, thus improving the convenience and range of use of the electromagnetic lock safety switch.
[0036] The locking head 41 in the locking assembly 4 allows for easy insertion of an external plug through the locking hole 42, and can also be inserted into the inner cavity of the retaining ring 51 in the limiting assembly 5 through the guide tube 43. By rotating the two limiting screws 53 into the inner cavities of the two first internal thread grooves 52, the two limiting screws 53 can be locked onto both sides of the annular groove 44 on the guide tube 43, thereby achieving the purpose of locking and limiting the guide tube 43 to prevent it from falling out of the inner cavity of the retaining ring 51, while not affecting the rotation of the locking head 41. This allows for flexible adjustment of the orientation of the locking head 41, making it convenient for the locking head 41 to lock and limit external plugs coming from any angle, improving the convenience and range of use of the electromagnetic lock safety switch. Through the mounting plate 54 and mounting screws 55, the retaining ring 51 can be stably and firmly fixed to the top surface of the inner cavity of the outer shell 1, thereby improving the stability of the retaining ring 51 and the locking head 41 in use.
[0037] By pushing the fixing seat 76 in component 7, it can be fixed to the inner wall of the outer shell 1 and the electric push rod 75 can be installed. When it is necessary to lock and limit the external plug inserted into the lock head 41, the electric push rod 75 can drive the hollow tube 72 to move upward via the push plate 71, thereby synchronously driving the top column 73 to move upward under the elastic force of the spring. Since the bottom end of the locking column 61 is rotatably connected to the connecting stud 74 on the top column 73 via the second internal thread groove 62, when the top column 73 moves upward, it will synchronously drive the locking column 61 to move upward, thus enabling... The locking pin 61 locks and limits the external plug inserted into the lock head 41, preventing the external plug from falling off the lock head 41. When it is necessary to release the external plug, the electric push rod 75 moves downward, which in turn moves the locking pin 61 downward, thus releasing the locking limit of the external plug. When the equipment is powered off or damaged, the user can remove the cover plate 2 and then drive the top pin 73 downward through the lever 77, which will also move the locking pin 61 downward, thus releasing the locking limit of the external plug.
[0038] In summary, this device, through the rotational adjustment of the lock head, can conveniently lock and limit the external plug coming from any angle, thereby improving the convenience and range of use of the electromagnetic lock safety switch.
