[0016] Figure 3 This is the front view of the device. DETAILED DESCRIPTION
[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.
[0018] Figures 1 to 3As shown, a distribution box anti-theft lock structure includes a fixed base 1 made by stamping a plate, and the fixed base 1 is divided into two separate parts: a main fixed base 1-1 and a secondary fixed base 1-2. A connecting hole 2 is provided on the fixed base 1, a lock hole 3 is provided on one side of the fixed base 1, a lock core is provided in the lock hole 3, and a torsion connecting plate 4 is connected to one side of the lock core. When the lock core is twisted by the key, the torsion connecting plate 4 rotates synchronously with the twisting of the lock core. A connecting rod 5 is connected to the torsion connecting plate 4 through a pin shaft, and the other end of the connecting rod 5 is connected to a lock tongue mounting plate 6 through another pin shaft. A lock tongue 7 is fixedly provided on one side of the lock tongue mounting plate 6. In this embodiment, the number of the lock tongues 7 is three, and these lock tongues 7 are arranged parallel to each other. When the device is installed in the distribution box, the three lock tongues 7 are arranged in sequence from top to bottom, which increases the connection strength between the box door and the box body.
[0019] The fixed base 1 is also provided with a vertical plate 8. Further optimized, the lock hole 3 is provided on the secondary fixed base 1-2, and the vertical plate 8 is provided on the main fixed base 1-1. Such a setting is conducive to installation and adjustment, and improves the convenience and accuracy of installation.
[0020] A guide structure is provided between the vertical plate 8 and the bolt mounting plate 6. In this embodiment, the guide structure is a guide hole 9 provided on the vertical plate 8 and a guide rod 10 fixed at one end on the bolt mounting plate 6, and the other end of the guide rod 10 is inserted into the guide hole 9. There are two guide holes 9 on the vertical plate 8, and there are also two guide rods 10 on the bolt mounting plate 6, and each guide hole 9 is penetrated by a corresponding guide rod 10. Further optimization, a limiting hole 11 is also provided on the vertical plate 8, and the connecting rod 5 passes through the limiting hole 11. In this embodiment, the connecting rod 5 is in the shape of a long strip, and the limiting hole 11 is in the shape of a strip, so the limiting hole 11 limits the connecting rod 5. Through these guide structures and limiting structures, the operation of the bolt mounting plate 6 is more accurate, and the structural strength is higher, which improves the anti-theft level. In other implementations, the guide structure can also be replaced by a slide groove or a slider.
[0021] For further optimization, the vertical plate 8 and the lock tongue mounting plate 6 are also provided with a push-pull mechanism, which is a compression spring 12 sleeved on the guide rod 10, and the two ends of the compression spring 12 are respectively against the plate surface of the vertical plate 8 and the lock tongue mounting plate 6. The push-pull structure applies a force to the lock tongue mounting plate 6, and this force makes the lock tongue tend to the lock tongue hole matching it, even if the device is in a locked state.
[0022] Further optimization, the right end of the fixed base 1 is also provided with an ear edge 13 perpendicular to its plate surface, and the ear edge 13 is provided with a lock tongue retaining hole 14, and the lock tongue passes through the lock tongue retaining hole 14.
[0023] The device can be fixed by passing bolts through the connection holes 2 on the fixed base 1, or it can be directly welded to the box door. The anti-theft lock structure of the distribution box is a mechanical connecting rod structure with high structural strength and low failure rate. In addition, a series of limiting structures such as multiple lock tongues and lock tongue holes are adopted to increase the overall strength of the structure, which can effectively prevent the door of the distribution box from being stolen or damaged by profiteering, and ensure the normal operation and safety of the oil field wellhead. It is fixed by spot welding studs on the inside of the door panel or directly welded as a whole, which is easy to install, can be modularly produced, and has high production efficiency. When a proprietary lock core is installed in the lock hole, the anti-theft ability is further enhanced and it is not easy to be copied or unlocked.
