Detailed Implementation
[0019] 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.
[0020] Please see Figure 1-3 This utility model provides a housing structure for a power adapter, including an adapter body 1;
[0021] Anti-theft component 2 is installed on one side of the outer wall of adapter body 1; anti-theft component 2 includes anti-theft box 21, cover plate 22, and lock cylinder 23;
[0022] The anti-theft box 21 is installed on one side of the outer wall of the adapter body 1 by means of bolt fixing or snap connection, forming a closed accommodating space inside. The opening design on one side of the outer wall of the anti-theft box 21 provides a mounting base for the hinge of the cover plate 22, and the outer wall has a through hole for the ratchet 4 to be inserted and operated.
[0023] The cover plate 22 is hinged to the edge of the opening on the outer wall of the anti-theft box 21 via a hinge, and can rotate flexibly around the hinge axis to completely close or open the opening. When the cover plate 22 is closed, its edge fits tightly against the edge of the opening of the anti-theft box 21, and together with the lock cylinder 23, it can form a complete closed structure, completely protecting the internal fastener 3 and the ratchet 4 connection part. When it is necessary to operate the ratchet 4, such as winding or unwinding it, the internal structure can be exposed by opening the cover plate 22. After the operation is completed, the cover plate 22 is closed and locked, which can restore the protective state.
[0024] The lock cylinder 23 is embedded through the cover plate 22, and its bolt can be slidably inserted into the corresponding lock hole of the anti-theft box 21. When the lock cylinder 23 is locked, the bolt and the lock hole are tightly engaged, restricting the rotation of the cover plate 22, thereby closing the opening of the anti-theft box 21 and preventing unauthorized personnel from opening the cover plate 22 and operating the internal structure. Only by inserting the matching key into the lock cylinder 23 and turning it can the bolt be driven to retract and the cover plate 22 be unlocked.
[0025] Fixing element 3 is installed on cover plate 22;
[0026] The ratchet 4 has one end set on the other side of the outer wall of the adapter body 1, and the other end can slide through the anti-theft component 2 for connection to the fastener 3.
[0027] The fastener 3 is used to fix the ratchet 4, which can be wrapped around an external object to fix the adapter body 1.
[0028] Specifically, refer to Figure 2 The fastener 3 includes a mounting shell 31, a ratchet block 32, and a spring 33;
[0029] The mounting housing 31 is fixed to the inner wall of the cover plate 22. Its interior is hollow, providing space for the ratchet block 32 and the spring 33 to be installed and moved. The outer wall of the mounting housing 31 has a through hole for the ratchet block 32 to pass through. The size of the through hole matches the cross-section of the ratchet block 32, which can not only ensure the smooth sliding of the ratchet block 32, but also guide it and prevent the ratchet block 32 from deviating during the movement.
[0030] The ratchet block 32 has a ratchet structure at one end that matches the ratchet rack 4, and a smooth plate-like structure at the other end. The ratchet block 32 can slide axially along the through hole of the mounting shell 31. When the ratchet end engages with the teeth on the ratchet rack 4, the one-way locking characteristic of the ratchet can be used to restrict the downward movement of the ratchet rack 4 and prevent the ratchet rack 4 from loosening from the fixed position. When the ratchet block 32 slides and disengages from the ratchet rack 4, the ratchet rack 4 can move freely. Compared with the ordinary snap-fit fixing structure, the engagement between the ratchet block 32 and the ratchet rack 4 has higher locking strength and stability, can withstand greater tensile force without loosening, and is more convenient and quick to fix.
[0031] Spring 33: One end is set on the rod-shaped part of the ratchet block 32 located inside the mounting housing 31, and the other end abuts against the inner wall of the mounting housing 31; In the natural state, spring 33 is in a compressed state, and pushes the ratchet block 32 towards the ratchet rack 4 through elastic force, so that the ratchet end of the ratchet block 32 always remains engaged with the ratchet rack 4, and the lock can be maintained without additional operation.
[0032] Specifically, refer to Figure 2 The mounting shell 31 has a U-shaped cross-section, which facilitates the sliding of the ratchet block 32 inside it and also guides and limits the ratchet block 32 to prevent it from deviating during sliding. The outer wall of the ratchet block 32 is provided with two limiting blocks 5 that can slide inside the mounting shell 31. When the ratchet block 32 slides inside the mounting shell 31, the limiting blocks 5 contact the inner wall of the mounting shell 31, limiting the sliding range of the ratchet block 32 and preventing it from falling out of the mounting shell 31, thus ensuring the integrity and reliability of the fastener 3 structure.
[0033] Specifically, refer to Figure 3 The adapter body 1 has a mounting bracket 6 on one side; one end of the ratchet 4 is connected to a T-shaped head 7 that can slide through the mounting bracket 6; a fixing screw 8 is set on the outer wall of the mounting bracket 6 and is used to fix the T-shaped head 7. After the T-shaped head 7 passes through the mounting bracket 6, the fixing screw 8 is tightened so that its end abuts against the T-shaped head 7, thereby fixing the T-shaped head 7 and realizing the detachable connection between the ratchet 4 and the adapter body 1; in this way, when different lengths of ratchet 4 are needed, the fixing screw 8 can be loosened, the T-shaped head 7 can be pulled out, a ratchet 4 of appropriate length can be replaced, and then it can be fixed again.
[0034] Working principle
[0035] In the initial state or when the adapter body 1 needs to be fixed, the ratchet block 32 in the fixing member 3 engages with the ratchet rack 4 under the elastic force of the spring 33, fixing the position of the ratchet rack 4; at this time, the cover plate 22 in the anti-theft component 2 is closed, and the lock cylinder 23 is inserted into the anti-theft box 21 and locked; if the adapter body 1 is to be fixed to an external object, use a key or other tools to open the lock cylinder 23 and unfold the cover plate 22. At this time, the fixing member 3 rotates with the cover plate 22 to disengage the ratchet block 32 from the ratchet rack 4, and the ratchet rack 4 can move freely. After the ratchet rack 4 is wrapped around the external object;
[0036] When the adapter body 1 is not needed, unfold the cover plate 22 to separate the fixing part 3 from the ratchet 4. The ratchet 4 can be retracted or moved, and the adapter body 1 returns to a freely movable state. When the ratchet 4 needs to be replaced, use the fixing screw 8 on the fixing bracket 6 to loosen and pull out the T-head 7, replace the new ratchet 4, and then tighten the fixing screw 8 to fix it, thus completing the replacement.
[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
