Description

Technical Field

[0001] The invention relates to an American box-type transformer, in particular to an American box-type transformer with an anti-theft function. Background Art

[0002] The American box transformer, also known as the American substation, is a compact transformer that contains the transformer in a closed metal box. This transformer has a compact design and a small footprint. It is often used in high-density load areas such as cities and industrial areas, and is also suitable for use in areas that are difficult to access. Due to its compactness and functionality, the American box transformer has become an important part of the modern urban power supply system.

[0003] However, American box-type transformers do not have an anti-theft mechanism, which has a negative effect on their safe operation. Since the transformer contains copper coils and other valuable metal materials, it is often targeted by theft. Theft not only causes direct economic losses, but also causes power outages, which brings great inconvenience to people's production and life. At the same time, the stolen transformer may not be fully restored during the reinstallation process, leaving safety hazards and increasing the difficulty and cost of future maintenance.

[0004] Therefore, the present invention aims to design an American box-type transformer with an anti-theft function to ensure the safe operation of the transformer. Summary of the invention

[0005] In order to overcome the disadvantage that the traditional American box-type transformer has no anti-theft mechanism, which leads to the theft of the transformer's internal materials and even power outages, causing great inconvenience to people's lives, the present invention provides an American box-type transformer with an anti-theft function.

[0006] An American box-type transformer with an anti-theft function comprises a box body, a radiator, a box door, a lock body, a mounting plate, a lock core, a protrusion, a driving gear, a lock piece and an alarm mechanism. A radiator is arranged at the back of the box body, and the box body is provided with box doors which are arranged oppositely and connected by hinge rotation. The left and right sides of the box door are a cover door and an inlaid door respectively, and the connection between the two can be sealed by engaging. The cover door part of the box door is fixedly connected to the lock body, and the inner end of the lock body is butt-jointed with a mounting plate. A lock core is rotatably connected to the lock body, and the lock core is an ordinary lock that needs to be rotated with a matching key. Protrusions are symmetrically fixedly connected to the periphery of the lock core, and the driving gear is rotatably connected to the front end of the mounting plate. The protrusion is slidably engaged in the driving gear. The driving gear is meshed with an alarm mechanism, and the alarm mechanism will be triggered when the driving gear rotates more than 90 degrees. A lock piece is fixedly connected to the mounting plate. After the lock core drives the driving gear to rotate 90 degrees, the lock core can slide into the lock piece, and the lock core can drive the lock piece to rotate and open the box door.

[0007] Furthermore, the lock is composed of a gear set and two locking rods. The gear set is composed of two gears that mesh with each other. One gear is rotatably connected to the mounting plate and is concentric with the driving gear. The inner wall of the gear is provided with a sliding groove that engages with the protrusion. The other gear is rotatably connected to the cover door part of the box door. The two locking rods are respectively rotatably connected to the eccentric parts of the two gears, and the ends of the locking rods can be slidably inserted into the box body.

[0008] Furthermore, the alarm mechanism includes a rack, a contact, a receiver and a buzzer. The rack is vertically slidably connected inside the cover door of the box door, the rack is meshed with the driving gear, a contact is arranged at the lower end of the rack, the receiver is arranged below the rack, the contact can contact the receiver, the buzzer is fixed to the top of the box body, and the buzzer and the receiver are electrically connected.

[0009] Furthermore, it also includes a driven gear, a transmission rod and a sealing plate. When the box door is closed, a straight groove is provided between the box door and the box body, the driven gear is rotatably connected in the box door, the driven gear and the gear set are meshed with each other and are located on both sides thereof, the transmission rod is laterally slidably connected to the box door, one end of the transmission rod is provided with teeth, the transmission rod is meshed with the driven gear through the teeth, and a sealing plate is fixedly connected to the other end of the transmission rod, the sealing plate is slidably connected to the connection between the box door and the box body, that is, in the above-mentioned straight groove, the sealing plate can not only fix the box door to prevent it from rotating to open.

[0010] Furthermore, the sealing plate is made of rubber.

[0011] Furthermore, it also includes a protective cover and a clamping rod. The protective cover is arranged outside the box door, specifically located outside the lock body. The clamping rod is slidably connected in the protective cover. A clamping groove is opened on the side of the rack. The clamping rod can be slidably embedded in the clamping groove to fix the rack.

[0012] Furthermore, it also includes a shift block, which is fixed to the clamping rod. A hole groove is opened at the bottom of the protective cover, and the hole groove is located at a corresponding position of the shift block.

[0013] Furthermore, it also includes a T-shaped control rod, which is slidably connected to the embedded door part of the box door, and a return spring is connected between the T-shaped control rod and the box door. When the cover door is closed, the T-shaped control rod can be pushed to move inward, and the T-shaped control rod will pass over the driven gear, and the driven gear can rotate freely. When the box door is rotated to open, the T-shaped control rod slides forward under the action of the return spring, and the T-shaped control rod can contact the driven gear and brake it.

[0014] The beneficial effects are: 1. When an illegal person turns the lock cylinder to a greater than specified angle without knowing the lock cylinder is open, the lock cylinder drives the rack to move downward through the active gear. After the contact touches the receiver, the buzzer will sound an alarm, and the card rod will be embedded in the rack and fix it. The illegal person cannot reset the rack in the reverse direction, so the buzzer will continue to sound to warn and deter the illegal person.

[0015] 2. The gear set drives the driven gear to rotate, and the driven gear drives the sealing plate to move horizontally through the transmission rod. The sealing plate can not only fix the box door to prevent it from turning and opening, but also improve the sealing performance of the box door.

[0016] 3. The driven gear is braked by the T-shaped control lever so that the sealing plate will not move disorderly when the box door is opened. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0030] Embodiment: An American box-type transformer with anti-theft function, such as Figure 1-Figure 6 As shown, it includes a box body 1, a radiator 101, a box door 2, a lock body 3, a mounting plate 301, a lock core 4, a protrusion 401, a driving gear 5, a lock and an alarm mechanism. The radiator 101 is arranged on the back of the box body 1. The box body 1 is equipped with a box door 2 that is arranged opposite to each other and is rotatably connected by a hinge. The left and right sides of the box door 2 are a cover door and an inlay door respectively. The connection between the two can be sealed by a chimeric way. The cover door part of the box door 2 is fixedly connected to the lock body 3, the inner end of the lock body 3 is connected to the mounting plate 301, and the lock core 4 is rotatably connected in the lock body 3. The lock core 4 is an ordinary lock that needs to be rotated with a matching key. The lock core 4 is symmetrically fixed with protrusions 401 on the periphery. The driving gear 5 is rotatably connected to the front end of the mounting plate 301. The protrusion 401 is slidably engaged in the driving gear 5. The driving gear 5 is meshed with an alarm mechanism. When the driving gear 5 rotates more than a specified angle (90 degrees in this embodiment), the alarm mechanism will be triggered. A lock piece is fixed on the mounting plate 301. After the lock core 4 drives the driving gear 5 to rotate 90 degrees, the lock core 4 can slide into the lock piece, and the lock core 4 can drive the lock piece to rotate to open the door 2.

[0031] like Figure 2-Figure 4 As shown, the lock is composed of a gear set 6 and two locking rods 7. The gear set 6 is composed of two gears meshing with each other, one of which is rotatably connected to the mounting plate 301 and is concentric with the driving gear 5. The inner wall of the gear is provided with a slide groove engaged with the protrusion 401. The other gear is rotatably connected to the cover door part of the box door 2. The two locking rods 7 are rotatably connected to the eccentric parts of the two gears respectively, and the ends of the locking rods 7 can be slidably inserted into the box body 1 to fix the box door 2.

[0032] like Figure 5 and Figure 6 As shown, the alarm mechanism includes a rack 8, a contact 9, a receiver 10 and a buzzer 11. The rack 8 is vertically slidably connected in the cover door of the box door 2. The rack 8 is meshed with the driving gear 5. The lower end of the rack 8 is provided with a contact 9. The receiver 10 is connected in the cover door of the box door 2 and is located below the rack 8. The contact 9 can contact the receiver 10. The buzzer 11 is fixed to the top of the box body 1. The buzzer 11 is electrically connected to the receiver 10. When an illegal person rotates the lock cylinder 4 more than 90 degrees, it will drive the rack 8 to move downward until the contact 9 contacts the receiver 10. At this time, the buzzer 11 will sound an alarm.

[0033] like Figure 2 , Figure 7 and Figure 8As shown, it also includes a driven gear 12, a transmission rod 13 and a sealing plate 14. When the box door 2 is closed, a straight groove is provided between the box door 2 and the box body 1, and the driven gear 12 is rotatably connected to the box doors 2 on both sides. The driven gear 12 is meshed with the gear set 6 and is located on both sides thereof. The transmission rod 13 is slidably connected to the box door 2 laterally. Teeth are provided at one end of the transmission rod 13, and the transmission rod 13 is meshed with the driven gear 12 on the same side through the teeth. A sealing plate 14 is fixedly connected to the other end of the transmission rod 13. The sealing plate 14 is made of rubber material. The sealing plate 14 is slidably connected to the connection between the box door 2 and the box body 1, that is, in the above-mentioned straight groove. The sealing plate 14 can not only fix the box door 2 to prevent it from rotating and opening, but also improve the sealing of the box door 2.

[0034] like Fig. 9 As shown, it also includes a protective cover 16, a lever 15 and a shift block 17. The protective cover 16 is arranged outside the box door 2, specifically outside the lock body 3. The lever 15 is slidably connected to the protective cover 16 and a compression spring is arranged between the two. A slot is provided on the side of the rack 8, and the lever 15 can be slidably embedded in the slot to fix the rack 8. The effect is that when an illegal person rotates the lock cylinder 4 more than 90 degrees, the contact 9 contacts the receiver 10, and then the buzzer 11 alarms. At this time, the lever 15 and the side of the rack 8 are in contact with each other. The card slots are aligned, and under the action of the compression spring, the card rod 15 can be inserted into the card slot to fix the rack 8, so that the rack 8 cannot slide and reset, and the buzzer 11 will continue to sound to deter illegal personnel. The dial block 17 is fixed to the card rod 15, and a hole groove is opened at the bottom of the protective cover 16. The hole groove is located at the corresponding position of the dial block 17. After receiving the alarm, the internal personnel rush to the scene, put their fingers deep into the bottom of the protective cover 16 and then dial the dial block 17 to separate the card rod 15 from the rack 8, thereby removing the alarm of the buzzer 11.

[0035] like Fig.10 and Fig.11 As shown, it also includes a T-shaped control rod 18, which is slidably connected to the embedded door part of the box door 2. A return spring is connected between the T-shaped control rod 18 and the box door 2. When the cover door is closed, the T-shaped control rod 18 can be pushed to move inward, and the T-shaped control rod 18 will pass over the driven gear 12, and the driven gear 12 can rotate freely. When the box door 2 is rotated to open, the T-shaped control rod 18 slides forward under the action of the return spring, and the T-shaped control rod 18 can contact the driven gear 12 and brake it. The effect is that the driven gear 12 will not rotate disorderly after the box door 2 is opened.

[0036] The working principle of the embodiment of the present invention is as follows: the insider inserts the key into the lock cylinder 4 and then rotates it 90 degrees counterclockwise, and then pushes the lock cylinder 4 backward until the protrusion 401 contacts the gear set 6, and rotates it 90 degrees again to drive the lock rod 7 to separate from the box body 1. At the same time, the gear set 6 drives the driven gear 12 to rotate, and the driven gear 12 drives the sealing plate 14 to slide toward each other through the transmission rod 13. At this time, the box door 2 can be rotated to open. If an illegal person attempts to unlock the door, the illegal person rotates the lock cylinder 4 more than 90 degrees without knowing that the lock cylinder 4 is opening, and the lock cylinder 4 drives the driving gear 5 to slide toward the lock cylinder 4. The movable rack 8 moves downward, and the contact 9 contacts the receiver 10, and the buzzer 11 will sound an alarm. At the same time, the card rod 15 will be embedded in the rack 8 and fix it. The illegal personnel cannot reset the rack 8 in the opposite direction, so the buzzer 11 will continue to sound to warn and deter the illegal personnel. After arriving at the scene, the internal personnel can disengage the card rod 15 from the rack 8 by toggling the dial block 17, and the rack 8 moves upward and resets, and the buzzer 11 is closed. When the box door 2 is opened, the T-shaped control rod 18 can limit and fix the driven gear 12 to prevent the driven gear 12 from driving the sealing plate 14 to move disorderly.

[0037] It should be understood that the above description is only for exemplary purposes and is not meant to limit the present invention. Those skilled in the art will appreciate that variations of the present invention will be included within the scope of the claims herein.
