DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] In order to clearly and completely describe the purpose, technical solution of the present utility model and make the advantages more clear, the following further details the embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present utility model, rather than all embodiments, and are only used to explain the embodiments of the present utility model, not to limit the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present utility model.

[0020] Embodiment 1: Please refer to Figures 1 to 4 , the present utility model provides a technical solution: a portable precision drawing instrument storage box, including: a box body 1, a box cover 2 is arranged on the surface of the box body 1, one end of the box body 1 is hinged to the box cover 2, a locking assembly is arranged at the other end of the box body 1 and the box cover 2, a key ring 15 is arranged at the top end of the box body 1, a key ring mounting seat 14 is fixed at the top end of the box body 1, one end of a rotating buckle 5 is rotatably connected to the surface of the key ring mounting seat 14, and the other end of the key ring 15 is rotatably connected to the rotating buckle 5.

[0021] During actual use, when the user wants to carry the portable precision drawing instrument storage box for movement, first use the locking assembly to lock the box body 1 and the box cover 2 together to prevent the instrument from falling out of the box body 1, and then hang it on the edge of the belt or pocket through the key ring 15 at the top end of the box body 1, and the portable precision drawing instrument storage box can be carried very conveniently without being held by hand, thus increasing the portability. At the same time, with the help of the key ring mounting seat 14 and the rotating buckle 5, the angle between the key ring 15 and the box body 1 can also be changed, making the end of the box body 1 away from the box cover 2 close to the body, and the box body 1 and the box cover 2 can also be prevented from being lifted too high, further increasing the portability.

[0022] Embodiment 2: On the basis of Embodiment 1, in order to achieve the convenient operation of the locking assembly, the locking assembly includes: a lock rod 3 and a lock seat 4, the lock rod 3 is fixed on the surface of the box cover 2, the box body 1 is fixed on the surface of the lock seat 4, the lock seat 4 is in a "U"-shaped plate structure, the lock rod 3 is rotatably connected between the two cross bars of the lock seat 4, a limiting groove 6 is opened on the surface of the lock rod 3, a limiting rod mounting groove 7 is opened on the surface of the lock seat 4, one end of a limiting rod 8 is movably inserted into the limiting rod mounting groove 7, the other end of the limiting rod 8 is movably inserted into the limiting groove 6, a spring 9 is fixed between the end of the limiting rod 8 extending into the limiting rod mounting groove 7 and the inner wall of the limiting rod mounting groove 7, a lever groove 10 is opened on the surface of the lock seat 4, the lever groove 10 communicates with the limiting rod mounting groove 7, a lever 11 is slidably connected in the lever groove 10, one end of the lever 11 is fixed on the surface of the limiting rod 8, and the other end of the lever 11 extends out of the lever groove 10.

[0023] When it is necessary to release the locking component, the lever 11 is toggled in a direction away from the lid 2. The lever 11 slides in the lever slot 10, driving the limit rod 8 to move in the same direction, causing the limit rod 8 to withdraw from the limit slot 6 and fully retract into the limit rod mounting slot 7. Then, the lid 2 can be rotated to withdraw the locking rod 3 from between the two cross bars of the lock base 4, and the locking is released. When it is necessary to restore the locking component, the lever 11 is toggled again in a direction away from the lid 2 to fully retract the limit rod 8 into the limit rod mounting slot 7, compressing the spring 9. Then, the lid 2 is rotated to return the locking rod 3 between the two cross bars of the lock base 4. At this time, the limit slot 6 is aligned with the limit rod mounting slot 7. Then, the lever 11 is released, and the spring 9 pushes one end of the limit rod 8 into the limit slot 6 under its elastic action, and the other end of the limit rod 8 stays in the limit rod mounting slot 7, and the locking is restored.

[0024] Embodiment 3: On the basis of Embodiment 2, in order to prevent sundries and dust from entering the limit rod mounting slot 7 and affecting the movement of the limit rod 8, a dust-proof plate receiving groove 12 is formed on the inner wall of the lever slot 10. One end of a dust-proof plate 13 is movably inserted into the dust-proof plate receiving groove 12, and the other end of the dust-proof plate 13 is fixed to the surface of the lever 11.

[0025] A dust-proof plate receiving groove 12 is formed on the inner wall of the lever slot 10. One end of a dust-proof plate 13 is movably inserted into the dust-proof plate receiving groove 12, and the other end of the dust-proof plate 13 is fixed to the surface of the lever 11, so that the dust-proof plate 13 seals the lever slot 10 to prevent sundries, dust, etc. from entering the limit rod mounting slot 7. When the lever 11 is toggled, the length of the dust-proof plate 13 inserted into the dust-proof plate receiving groove 12 is adjustable, so as to prevent the dust-proof plate 13 from affecting the toggling of the lever 11.

[0026] In actual use, when the user wants to carry the portable precision drawing instrument storage box for movement, first use the locking component to lock the box body 1 and the box cover 2 together to prevent the instrument from falling out of the box body 1. Then, hang it on the edge of the belt or pocket through the key ring 15 at the top of the box body 1. Thus, it is very convenient to carry the portable precision drawing instrument storage box without holding it by hand, which increases the portability. At the same time, with the help of the key ring mounting seat 14 and the rotating buckle 5, the angle between the key ring 15 and the box body 1 can also be changed, making the end of the box body 1 away from the box cover 2 close to the body, and it can also prevent the box body 1 and the box cover 2 from being lifted too high, further increasing the portability. When it is necessary to release the locking component, move the lever 11 in the direction away from the box cover 2. The lever 11 slides in the lever slot 10, driving the limit rod 8 to move in the same direction, so that the limit rod 8 withdraws from the limit slot 6 and completely retracts into the limit rod mounting slot 7. Then, the box cover 2 can be rotated to make the locking rod 3 withdraw from between the two cross bars of the lock seat 4, and the locking is released. When it is necessary to restore the locking component, move the lever 11 in the direction away from the box cover 2 again to make the limit rod 8 completely retract into the limit rod mounting slot 7, so that the spring 9 is compressed. Then, rotate the box cover 2 to make the locking rod 3 return between the two cross bars of the lock seat 4. At this time, the limit slot 6 is aligned with the limit rod mounting slot 7. Then, release the lever 11, and the spring 9 will push one end of the limit rod 8 into the limit slot 6 under the elastic action, and the other end of the limit rod 8 stays in the limit rod mounting slot 7, and the locking is restored. A dust-proof plate storage slot 12 is formed on the inner wall of the lever slot 10. One end of a dust-proof plate 13 is movably inserted into the dust-proof plate storage slot 12, and the other end of the dust-proof plate 13 is fixed on the surface of the lever 11. Thus, the dust-proof plate 13 seals the lever slot 10 to prevent sundries, dust, etc. from entering the limit rod mounting slot 7. When the lever 11 is moved, the length of the dust-proof plate 13 inserted into the dust-proof plate storage slot 12 is adjustable, so as to prevent the dust-proof plate 13 from affecting the movement of the lever 11.

[0027] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
