Abstract

The present invention discloses an intelligent lead lock for a meter box, comprising a steel wire rope, a lock body, a locking button, a rotary fork, a locking module, and a driving module. The driving module is used to drive the locking button to axially displace so that the locking button contacts or moves away from one end of the rotary fork. The locking module comprises a lock core and an upper sleeve. One end of the steel wire rope passes through the lock core, and the other end of the steel wire rope passes through the outside of the lock body. The other end of the rotary fork contacts or is provided with a gap with the lock core. When the steel wire rope pulls the lock core to displace it so that it is engaged in the upper sleeve, the lock core and the steel wire rope are radially engaged, and the locking button contacts the rotary fork. When the rotary fork drives the lock core to displace it, it is separated from the upper sleeve, the lock core and the steel wire rope are in a gap, and the locking button moves away from the rotary fork. The present invention realizes effective locking of the meter box by providing a structure in which the steel wire rope cooperates with the movable lock core.

[0027] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the present invention.

[0028] like Figure 1 As shown, the present invention provides an intelligent lead lock for a meter box, which includes a steel wire rope 1, a lock body 2, and a locking button 3, a rotary fork 4, a locking module 5, a driving module 6, a torsion spring 7, a wireless power supply module 8 and a sensor 9 arranged in the lock body 2.

[0029] A lock hole is provided on one side wall of the lock body 2 , one end of the steel wire rope 1 is connected to the outer shell of the meter box, and the other end is a free end that can be inserted into the lock hole and connected to the locking module 5 inside the lock body 2 .

[0030] The lock body 2 is a rectangular box structure, the locking module 5 is arranged on one side of the interior thereof, and the locking button 3 is located beside the locking module 5, and the axis of the locking button 3 and the axis of the locking module 5 are perpendicular to each other. The rotary fork 4 is arranged between the locking button 3 and the locking module 5. The rotary fork 4 is provided with a first driving arm 41 corresponding to the position of the locking button 3 and a second driving arm 42 corresponding to the position of the locking module 5. The first driving arm 41 and the second driving arm 42 are perpendicular to each other. The rotary fork 4 is provided with a driving arm for driving the rotary fork 4 along the locking button 3. Figure 1 The torsion spring 7 rotates clockwise, and the locking button 3 rotates along the rotating fork 4. Figure 1 The torsion spring 7 is mounted on the middle portion of the rotary fork 4, and one end of the torsion spring 7 abuts against the end surface of the spring seat 53, and the other end abuts against the lower surface of the first drive arm 41 of the rotary fork 4.

[0031] like Figure 2 、 Figure 3 As shown, the locking module 5 includes a lock core 51 , an upper sleeve 52 and a spring seat 53 .

[0032] The end of the locking button 3, distal from the first actuating arm 41, extends outward from the lock body 2. The actuating module 6 is disposed below the locking button 3. The lock core 51 comprises a head 511 at its front end, a second lever 512 in its center, and a through-hole 513 within it for the flexible wire rope 1 to pass through. The flexible wire rope 1 passes through the upper sleeve 52 and fits within the through-hole 513 with a clearance. (The size of this clearance must be designed to ensure that the flexible wire rope can pull the lock core 51 and, to ensure sufficient displacement, the flexible wire rope 1 must extend into the lock core 51). The head 511 is conical, with at least three radially arranged mounting holes. A steel ball 514 is mounted in each mounting hole. The steel ball 514 fits within the mounting hole with a clearance, allowing it to extend toward the through-hole 513 when a radial external force is applied. The second lever 512 is perpendicular to the axial direction of the main structure of the lock core 51.

[0033] The upper sleeve 52 is fitted with the spring seat 53. The upper sleeve 52 has a tapered hole on one end facing the spring seat 53 that matches the head 511. The spring seat 53 has a slideway 531. The tapered hole is connected to the slideway 531, and the lock core 51 is slidably arranged therein. The spring seat 53 is also provided with a slot for the second lever 512 to extend out. Figure 1 As shown, the second driving arm 42 is adapted to the second shifting rod 512 on the side close to the upper sleeve 52 .

[0034] like Figure 1As shown, the drive module 6 includes a motor 61, an unlocking wheel 62, a steel ball 63, and a cam 64. The cam 64 has a large diameter and a small diameter. The cam 64 is arranged on the end face of the motor 61 where the motor shaft is provided. The small diameter of the cam 64 is used to limit the rotation of the unlocking wheel 62.

[0035] The motor shaft of the motor 61 is connected to the unlocking wheel 62, which is provided with two first grooves 621 adapted to the steel ball 63, and the locking button 3 is provided with a second groove 31 adapted to the steel ball 63. The unlocking wheel 62 is provided with a first lever 622 adapted to the minor diameter of the cam 64.

[0036] A wireless power supply module 8 is provided below the motor 61 , and the wireless power supply module 8 can drive the motor 61 to rotate forward and reverse.

[0037] The locking button 3 is capable of horizontal axial displacement. When it contacts the first drive arm 41 of the rotary fork 4, the steel ball 63 is positioned in the second groove 31 and abuts the outer wall of the unlocking wheel 62. The engagement of the steel ball 63 with the second groove 31 defines the axial position of the locking button 3. Consequently, the compressive force applied by the locking button 3 on the first drive arm 41 is greater than the elastic force of the torsion spring 7, preventing the second drive arm 42 from contacting the second lever 512. Alternatively, contact can be achieved without applying a thrust. At this point, the steel cord 1 pulls the lock core 51 toward the upper sleeve 52, causing the tapered head 511 to extend into the tapered hole of the upper sleeve 52. As the tapered aperture gradually decreases, the inner wall of the tapered hole simultaneously pushes the steel ball 514 radially outward, abutting and compressing the steel cord 1 within the through hole 513, thereby locking the lead lock.

[0038] If the lead lock needs to be released, a signal is sent to the wireless power supply module 8 to drive the motor 61 to rotate. When the first lever 622 abuts the side wall of the small diameter circle of the cam 64, the steel ball 63 is located in the first groove 621. At this time, the steel ball 63 is spaced apart from the locking button 3. After the locking button 3 is unconstrained, the pressure on the first drive arm 41 is less than the elastic force of the torsion spring 7, causing the rotary fork 4 to rotate clockwise under the action of the torsion spring 7, causing the second drive arm 42 to contact the second lever 512, pushing the lock core 51 toward the spring seat 53. At this time, the tapered hole of the upper sleeve 52 and the steel ball 514 are spaced apart, releasing the pressure on the steel ball 514, thereby releasing the pressure on the steel cord 1, allowing the steel cord 1 to be pulled out of the lock hole of the lock body 2, and releasing the lead lock.

[0039] The wireless power supply module 8 is connected to the motor 61 and can realize forward and reverse rotation under the control of the circuit to control the rotation of the unlocking wheel 62.

[0040] The sensor 9 is arranged in the lock body 2 and is located on the side of the lock button 3 away from the driving module 6. The sensor 9 is used to sense the action of the lock button 3 and send a signal to the handheld device.

[0041] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
