Description

Technical Field

[0001] This utility model relates to the field of computer key technology, and in particular to a computer key with protective function. Background Technology

[0002] Computer keys are an important tool in power systems to prevent misoperation. They play a key role in practical applications. They mainly receive the operation program from the anti-misoperation host, identify and control the correct unlocking of the coded lock, and transmit the operation sequence back to the anti-misoperation host.

[0003] A search revealed Chinese Patent Publication No. CN205992254U, which discloses a computer key including an unlocking device. The unlocking device includes an unlocking lever and a fixing lever for mounting the unlocking lever. The unlocking lever and fixing lever are detachably connected. Because the unlocking lever on this computer key is detachable, when it is damaged due to prolonged use, improper operation, or accidental drop from a height, it can be quickly replaced by disassembling and reassembling the unlocking lever, improving work efficiency. It also avoids discarding the entire computer key due to unlocking lever damage, extending the key's lifespan and saving costs. Furthermore, it improves reliability and increases safety in the event of sudden emergencies.

[0004] While the aforementioned technology enables the replacement of the unlocking lever, it directly exposes the lever to the outside, which can easily cause bending, wear, contamination, and corrosion, thus affecting its service life. Therefore, a computer key with protective functions is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a computer key with protective function, which aims to improve the problem in the prior art where the unlocking rod is directly exposed to the outside, which is prone to bending, wear, and contamination and corrosion, thus affecting the service life.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a computer key with protective function, comprising a computer key body, a protective groove on the right side of the computer key body, a protective component on the right side inside the protective groove, the protective component including a flip cover, the front and rear ends of the flip cover being rotatably connected to the inner wall of the protective groove, a locking component on the left side of the inner wall of the protective groove, an adjustment component between the front of the computer key body and the inside of the protective groove, the adjustment component including a rotating shaft, the front and rear ends of the rotating shaft being rotatably connected to the inner wall of the protective groove, a pointing handle fixedly connected to the front end of the rotating shaft through the front of the computer key body, and an unlocking rod fixedly connected to the center of the bottom of the rotating shaft.

[0007] As a further description of the above technical solution:

[0008] A sealing plate is fixedly connected to the upper left edge of the flip cover, and locking pins are fixedly connected to the left side of the flip cover and at both ends of the sealing plate. A latch is fixedly connected to the right side of the top of the flip cover.

[0009] As a further description of the above technical solution:

[0010] The locking assembly includes an upper fixed seat and a lower fixed seat. The left sides of both the upper and lower fixed seats are fixedly connected to the left side of the inner wall of the protective groove. A guide rod is fixedly connected between adjacent sides of the upper and lower fixed seats. A movable slide is movably sleeved on the outer periphery of the guide rod.

[0011] As a further description of the above technical solution:

[0012] Locking pins are fixedly connected to both the front and rear ends of the bottom of the movable slide, and a spring is sleeved on the outer periphery of the guide rod and located on the upper edge of the movable slide.

[0013] As a further description of the above technical solution:

[0014] A pull rod is embedded in the top left side of the upper fixed seat, and the bottom end of the pull rod is fixedly connected to the top of the movable slide. The upper fixed seat has locking holes at both the front and rear ends on the right side.

[0015] As a further description of the above technical solution:

[0016] The size of the locking pin connection end is adapted to fit into the inside of the locking hole.

[0017] As a further description of the above technical solution:

[0018] Locking holes are provided at both the front and rear ends of the top of the shaft, and the size of the locking holes is adapted to install locking pins.

[0019] As a further description of the above technical solution:

[0020] The front of the computer key body is fixedly connected to a display screen and control buttons from top to bottom, and an unlocking device is fixedly connected to the center of the top of the computer key body.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, through the locking component and the adjusting component, the movable slide can be pulled by the pull rod to move upward along the guide rod to compress the spring, so that the locking pin at its bottom leaves the lock hole. Then, by rotating the shaft with the pointing handle, the unlocking rod on the shaft can be raised to unlock or folded into the protective groove for sealing and protection. The position of the lock hole of the rotating shaft can be observed by the pointing handle with the pointing mark, and the unlocking rod can be raised or folded for quick locking. The adjustable and foldable unlocking rod structure effectively avoids wear and bending of the unlocking rod and improves the service life of the unlocking rod.

[0023] 2. In this utility model, the protective groove and protective components are engaged with the inside of the card hole by the card pin, so that the flip cover can be closed and sealed by the protective groove, thereby facilitating the use of the waterproof, dustproof, sealed, protective, and unlocking rod.

The latch 63 is fitted into the latch hole 78 by the size of the connecting end of the latch 63, so that the flip cover 61 can be closed to seal the protective groove 5. A pry plate 64 for force to pry open the flip cover 61 is fixedly connected to the right side of the top of the flip cover 61.

[0032] Reference Figures 1-4A locking assembly 7 for locking and fixing the adjusting assembly 8 is provided on the left side of the inner wall of the protective groove 5. The locking assembly 7 includes an upper fixing seat 71 and a lower fixing seat 72 fixedly connected to the left side of the inner wall of the protective groove 5. A guide rod 73 is fixedly connected between adjacent sides of the upper fixing seat 71 and the lower fixing seat 72. A movable slide 74 is movably sleeved on the outer periphery of the guide rod 73. Locking pins 75 for locking the adjusting assembly 8 are fixedly connected to both the front and rear ends of the bottom of the movable slide 74. A retractable spring 76 is sleeved on the outer periphery of the guide rod 73 and on the upper edge of the movable slide 74. A pull rod 77 for adjusting the movement of the movable slide 74 is embedded and connected to the top left side of the upper fixing seat 71. The bottom end of the pull rod 77 is fixedly connected to the top of the movable slide 74. Locking holes 82 are provided at both the front and rear ends of the top of the rotating shaft 81, and the size of the locking holes 82 is adapted to the... Installing the locking pin 75 allows the movable slide 74 to be pulled upwards via the pull rod 77 to compress the spring 76, causing the locking pin 75 at its bottom to disengage from the lock hole 82. This, in turn, rotates the shaft 81, changing the unlocking lever 9 on the shaft 81 to lift it up for unlocking or fold it into the protective groove 5 for sealing and protection. An adjustment component 8 is provided between the front of the computer key body 1 and the inside of the protective groove 5 to drive the unlocking lever 9 to rotate.
