[0024] 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.

[0025] like Figures 1 to 5As shown, the present invention provides a pen with a drop-proof protective cover, including a pen barrel 1, a pen tip 2 and a protective cover 3. The protective cover 3 is threadedly connected to the surface of the pen barrel 1, the pen tip 2 is fixedly installed at the bottom of the pen barrel 1, a sealing block 4 is provided at the bottom inside the protective cover 3, a limit block 5 is fixedly connected to the bottom of the sealing block 4, and quick fixing mechanisms 6 are provided on the left and right sides of the surface of the sealing block 4.

[0026] refer to Figure 2 , Figure 4 and Figure 5 The quick-fixing mechanism 6 includes a telescopic groove 61, which is opened on the left and right sides of the surface of the sealing block 4. A locking block 62 is slidably connected inside the telescopic groove 61. A locking groove 63 is opened at the bottom of the inner wall of the protective sleeve 3. The locking groove 63 is used in conjunction with the locking block 62. A clamping component 65 is fixedly connected to the top and bottom of the inner side of the locking block 62. An unlocking component 66 is fixedly connected to the front and back of the locking block 62.

[0027] As a technical optimization of this utility model, by setting up a quick fixing mechanism 6, when the sealing block 4 is needed to seal the protective sleeve 3, the operator inserts the sealing block 4 into the protective sleeve 3. During the gradual insertion process, the locking block 62 will be released by the elastic force of the pressing component 65 and stick tightly to the inner wall of the protective sleeve 3. When it moves to the locking groove 63 position, the elastic force will drive the locking block 62 to move outward through the telescopic groove 61, so that the locking block 62 is stuck inside the locking groove 63, thereby completing the quick fixing of the sealing block 4 and ensuring the convenience of the operator to seal the protective sleeve 3.

[0028] refer to Figure 2 , Figure 4 and Figure 5 The clamping component 65 includes a spring 651, which is fixedly connected to the top and bottom of the inner side of the locking block 62. The end of the spring 651 away from the locking block 62 is fixedly connected to a support block 652, and the top of the support block 652 is fixedly connected to the sealing block 4.

[0029] As a technical optimization of this utility model, by setting the clamping component 65, the spring 651 applies pressure to the locking block 62 through the support of the support block 652, so that the locking block 62 can be tightly fixed in the locking groove 63, preventing the sealing block 4 from being opened accidentally.

[0030] refer to Figure 2 , Figure 4 and Figure 5The unlocking component 66 includes an unlocking block 661, which is fixedly connected to the front and back of the locking block 62. An unlocking bracket 662 is slidably connected to the surface of the unlocking block 661. Unlocking slots 663 are provided on the left and right sides of the front and the left and right sides of the back of the unlocking bracket 662. The two unlocking slots 663 are arranged in a V-shape. The unlocking block 661 is located inside the unlocking slot 663. An unlocking pull rod 664 is fixedly connected to the bottom of the unlocking bracket 662. The bottom end of the unlocking pull rod 664 passes through a through hole and extends to the outside of the limiting block 5.

[0031] As a technical optimization of this utility model, by setting the unlocking component 66, when it is necessary to pull out the sealing block 4 to open the protective sleeve 3, the operator pulls down the unlocking lever 664, causing the unlocking lever 664 to drive the unlocking frame 662 to move downward, thereby causing the unlocking frame 662 to drive the unlocking rod to move inward through the unlocking groove 663, and then causing the unlocking rod to drive the locking block 62 to retract inward and disengage from the locking groove 63, so that the operator can quickly remove the sealing block 4 from the protective sleeve 3.

[0032] refer to Figure 2 , Figure 4 and Figure 5 The top of the sealing block 4 is covered with a protective pad 7, which is made of natural rubber.

[0033] As a technical optimization of this utility model, by setting a protective pad 7, when the sealing block 4 forms a seal on the protective sleeve 3, the protective pad 7 will wrap around the pen tip 2, thereby further protecting the pen tip 2 and improving the protective effect of the pen tip 2.

[0034] refer to Figure 2 , Figure 4 and Figure 5 The top of the pen barrel 1 is fixedly connected to a placement insertion hole 8, the diameter of which is adapted to the diameter of the unlocking lever 664.

[0035] As a technical optimization of this utility model, by setting a placement insertion hole 8, when the operator pulls out the sealing block 4, the unlocking lever 664 can be inserted into the placement insertion hole 8, thereby enabling the pen 1 to provide a placement point for the sealing block 4 and reducing the possibility of the sealing block 4 being lost.

[0036] refer to Figure 2 , Figure 4 and Figure 5 Figure 2 Figure 4 Figure 5 The outer end of the locking block 62 is set as an inclined surface.

[0037] As a technical optimization of this utility model, by setting the outer end of the locking block 62 as an inclined surface, the operator can insert the sealing block 4 more smoothly.

[0038] The working principle and usage process of this utility model are as follows: When the operator does not need to use the pen, they rotate the protective sleeve 3, causing it to move downwards via the threads. This protects the pen tip 2 from injury. Then, the operator inserts the sealing block 4 into the bottom of the protective sleeve 3. During insertion, the spring 651, supported by the support block 652, applies pressure to the locking block 62. The locking block 62 is released by the spring force of the spring 651 and adheres tightly to the inner wall of the protective sleeve 3. When it moves to the locking groove 63, the spring force causes the locking block 62 to move outwards through the telescopic groove 61, locking it inside the locking groove 63. This quickly fixes the sealing block 4, thereby securing the sealing block 4 and the limiting block. 5. The exposed protective cover 3 is sealed to prevent impurities and other particles from entering the pen tip 2 and causing blockage or damage. When the operator needs to use the pen, the operator pulls down the unlocking lever 664, which moves the unlocking bracket 662 downward. This causes the unlocking bracket 662 to move the unlocking rod inward through the unlocking groove 663, which in turn causes the unlocking rod to retract the locking block 62 inward and disengage it from the locking groove 63. This allows the operator to quickly remove the sealing block 4 from the protective cover 3 and write conveniently. When the operator pulls out the sealing block 4, the unlocking lever 664 can be inserted into the placement insertion hole 8, so that the pen barrel 1 can provide a placement point for the sealing block 4, reducing the possibility of the sealing block 4 being lost.

[0039] In summary, this pen with a drop-proof protective sleeve, by setting a sealing block 4, allows the operator to insert the sealing block 4 into the bottom of the protective sleeve 3 when the protective sleeve 3 is protecting the pen tip 2. This seals the exposed bottom of the protective sleeve 3, preventing the pen tip 2 from being clogged by impurities. At the same time, the limiting block 5 at the bottom of the sealing block 4 ensures that the insertion of the sealing block 4 will not contact the pen tip 2, preventing the pen tip 2 from rubbing against the sealing block 4. This solves the problem that when the protective sleeve is protecting the pen tip, its bottom is exposed, which means that impurities or larger particles may enter the pen tip surface through this exposed part during the process of carrying the pen.
