Description

Technical Field

[0001] The utility model relates to a writing tool, in particular to a push-type writing tool with a movable cover for sealing. Background Art

[0002] A press-type writing tool is a writing tool that switches between the two states of press-to-extend and press-to-retract through the cooperation of a pressing action and an actuator structure. This type of writing tool does not require an additional pen cap for use, making it more convenient to use and carry.

[0003] However, this type of push-type writing tool has a defect. Since the ink outlet of the inner core of the writing tool is directly exposed to the air, it is easy to cause the ink outlet to dry out and become blocked, resulting in unsmooth writing.

[0004] This kind of problem is particularly evident in writing tools such as pens. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a push-type writing tool with a movable cover for sealing, which can alleviate the problem of drying of the ink outlet and the problem of clogging of the ink outlet caused by ink drying, so that writing can be maintained smoothly every time it is used.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: A push-type writing tool with a movable cover for sealing, comprising a pen barrel, an actuating mechanism arranged in the pen barrel, and a refill arranged in the pen barrel, the actuating mechanism cooperates with the refill to drive the refill to extend and retract, a cover is rotatably provided at a position corresponding to the nib in the pen barrel, the refill cooperates with the cover, when the tip of the refill extends out of the nib, the cover is opened after being rotated to allow the nib to extend, and when the tip of the refill is retracted, the cover is closed after being rotated.

[0007] As a further improvement of the present invention, a linkage member is arranged in the pen barrel, the linkage member is linked with the pen core, and the linkage member is slidably arranged in the pen barrel along the axial direction of the pen barrel. The linkage member slides in cooperation with the pen core and drives the cover to rotate and open as the pen core is extended.

[0008] As a further improvement of the present invention, a damping block is arranged on the linkage member, and a slider is arranged on the refill at a position corresponding to the damping block, and the slider cooperates with the damping block to form damping, so as to drive the linkage member to slide through the extension and retraction of the refill.

[0010] As a further improvement of the present invention, the damping block and / or the slider are elastic. When the pen core is in a retracted state, the slider is located above the damping block, and through the cooperation between the slider and the damping block, the linkage part is driven to move toward the pen tip when the pen core is extended, and when the linkage part moves into place, the cover is flipped open, and as the pen core continues to extend, the slider moves to below the damping block, and the tip of the pen core is extended; when the pen core is in an extended state, the slider is located below the damping block, and as the pen core is retracted, the slider cooperates with the damping block to move the linkage part toward a position away from the pen tip, and when the linkage part moves into place and the pen core continues to move, the slider moves above the damping block.

[0011] As a further improvement of the present invention, a sealing ring is further provided in the pen holder at a position corresponding to the pen tip, and the sealing ring cooperates with the cover to seal.

[0024] The present invention will be further described below with reference to the embodiments given in the accompanying drawings.

[0025] Reference Figure 1-8 As shown,

[0026] A push-type writing tool with a movable cover for sealing comprises a pen barrel 1, an actuating mechanism 2 arranged in the pen barrel 1, and a refill 3 arranged in the pen barrel 1. The actuating mechanism 2 cooperates with the refill 3 to drive the refill 3 to move telescopically. A cover 4 is rotatably arranged at a position corresponding to a nib 11 in the pen barrel 1. The refill 3 cooperates with the cover 4. When a nib 31 of the refill 3 extends out of the nib 11, the cover 4 is rotated to open so that the nib 11 can be extended, and when the nib 31 of the refill 3 is retracted, the cover 4 is rotated to close.

[0027] First of all, it needs to be explained that the actuator mechanism 2 is currently a mature mechanical structure for a press-type writing tool, which cooperates with a spring to realize the functions of press-lock and press-unlock and pop-up. We will not go into details here. Those skilled in the art can refer to the spring in the figure and implement it in coordination with the actuator mechanism 2, or they can choose a conventional actuator mechanism 2 for implementation.

[0028] The pen holder 1 serves as a shell and can be held by a user.

[0029] When the refill 3 in this solution is extended with the cooperation of the movable structure, it can work by means of the linkage cover 4. When the refill 3 is extended, the cover 4 is driven to rotate and open, so that the refill 3 can be smoothly extended for the user to write. When the refill 3 is retracted with the cooperation of the movable mechanism 2 again, the cover 4 is driven to rotate again, so that it is in the closed state again, which can shield the refill 3, alleviate or slow down the problem of the nib 31 of the refill 3 drying, and improve the writing experience.

[0030] The cooperation between the pen core 3 and the cover 4 in the above structure can be linked by pushing open the cover 4 when the pen core 3 is extended, and the cover 4 can be equipped with a torsion spring, which is used to maintain the movement trend toward the cover. When the pen core 3 is retracted, the cover 4 is restored by the elastic force of the torsion spring and is in the closed state again.

[0031] The specific linkage structure of the cover 4 can be as follows: a linkage part 5 is arranged in the pen body 1, and the linkage part 5 is linked with the pen core 3, and the linkage part 5 is slidably arranged in the pen body 1 along the axial direction of the pen body 1, and the linkage part 5 slides with the pen core 3, and drives the cover 4 to rotate and open as the pen core 3 extends.

[0032] The linkage member 5 itself can slide inside the pen body 1. The pen core 3 is moved with the linkage member 5, and the linkage member 5 is used to drive the cover 4 to open or close. This can reduce the impact on the pen core 3, allowing the pen core 3 to be extended normally for writing, and avoiding the pen core 3 and the pen tip 31 from directly contacting the cover 4 to affect the service life.

[0033] In order to optimize the matching state between the refill 3 and the linkage member 5, a damping block 51 is provided on the linkage member 5, and a slider 32 is provided at a position corresponding to the damping block 51 on the refill 3. The slider 32 cooperates with the damping block 51 to form damping, so as to drive the linkage member 5 to slide through the extension and retraction of the refill 3.

[0034] The cooperation between the slider 32 and the damping block 51 can form a linkage, so that when the pen core 3 extends downward, damping is generated between the slider 32 and the damping block 51, and then the linkage member 5 moves downward, and the linkage member 5 is used to open the cover 4.

[0035] The linkage member 5 can be reset by means of a spring. For example, when the refill 3 is pressed down, the spring connected to the linkage member 5 can be compressed and linked with the damping block 51. When the refill 3 is restored, the linkage member 5 can also be reset. The damping block 51 and the slider 32 cooperate to facilitate installation. The writing tool is made of plastic material and has a certain elasticity, making it more convenient to install.

[0036] Of course, further optimization can be performed to further save installation costs and increase installation efficiency. The cover 4 is rotatably connected to the linkage member 5, and a limit slot 12 is provided at the position of the pen tip 11 of the pen holder 1. One end of the cover 4 corresponding to the limit slot 12 is located in the limit slot 12, and the other end switches between the closed and open states by rotation; when the linkage member 5 moves downward, it moves with the cover 4, and cooperates with the limit slot 12 to drive the cover 4 to rotate.

[0037] The limiting groove 12 can be achieved by setting a groove on the part of the pen mouth 11, and then installing the pen mouth 11 to the pen body 1 in a detachable manner (such as threaded connection, interference fit, snap connection, etc.). After installation, the groove cooperates with the inside of the pen body 1 to form the limiting groove 12. This cooperation method is simpler to install and convenient for the installation of the linkage part, allowing the linkage part 5 to more conveniently form a cooperation relationship with the limiting groove 12.

[0038] The cover 4 is rotatably connected to the linkage 5, so that the cover 4 can be opened or closed when the pen core 3 moves with the linkage 5. Since the cover 4 is rotatably connected to the linkage 5, for example, rotatably connected via a rotating shaft, one end of the cover 4 is located in the limiting groove 12. Therefore, during the extension and retraction of the linkage 5, one end of the cover 4 is limited by the limiting groove 12, and the other end can switch between the open and closed states.

[0039] It should be noted that the state of opening the cover 4 needs to be before the pen core 3 contacts the cover 4, and the state of closing the cover 4 needs to be after the pen core 3 is retracted.

[0040] In order to better achieve this effect, the damping block 51 and / or the slider 32 are elastic. When the refill 3 is in the retracted state, the slider 32 is located above the damping block 51, and through the cooperation between the slider 32 and the damping block 51, the linkage member 5 is driven to move toward the nib 11 when the refill 3 is extended, and when the linkage member 5 moves into place, the cover 4 is flipped open, and as the refill 3 continues to extend, the slider 32 moves below the damping block 51, and the tip 31 of the refill 3 is extended; when the refill 3 is in the extended state, the slider 32 is located below the damping block 51, and as the refill 3 is retracted, the slider 32 cooperates with the damping block 51 to move the linkage member 5 toward a position away from the nib 11, and when the linkage member 5 moves into place and the refill 3 continues to move, the slider 32 moves above the damping block 51.

[0041] By utilizing the elastic force and sliding action between the damping block 51 and the slider 32, when the pen core 3 is extended, the slider 32 and the damping block 51 cooperate to drive the linkage member 5. During this process, the linkage member 5 cooperates with the limiting groove 12 to open the cover 4. Then, as the pen core 3 continues to move, the slider 32 will slide down to the bottom of the damping block 51. At this time, the damping action of the damping block 51 is released, and the pen core 3 extends out from the pen mouth 11 after the cover 4 is opened. When the pen core 3 is retracted, the pen core 3 moves upward until the slider 32 cooperates with the damping block 51, and moves the linkage member 5 upward. During this process, the linkage member 5 cooperates with the limiting groove 12 to cover the cover 4 until the linkage member 5 moves into place and the pen core 3 continues to move upward. At this time, the slider 32 returns to the top of the damping block 51.

[0042] The above structure allows the pen tip 31 to be extended before the cover 4 is opened, and allows the pen tip 31 to be retracted before the cover 4 is closed, which can further protect the pen tip 31 and prevent the pen tip 31 from being damaged and affecting the writing effect.

[0043] The problem of ink drying can be alleviated by opening and closing the cover 4. In order to further improve the effect of isolating air, the following method can be selected for optimization: a sealing ring 6 is further provided at the position corresponding to the pen tip 11 in the pen barrel 1. The sealing ring 6 cooperates with the cover 4 for sealing. When the cover 4 is in the closed state, the cover 4 abuts against the sealing ring 6 to form a seal. The sealing ring 6 is used to cooperate with the cover 4 for closing, which can improve the sealing effect, make it more difficult for air to circulate, and further slow down the drying speed of the ink.

[0044] In the preferred structure, the linkage member 5 is cylindrical, the refill 3 is inserted into the hollow position of the linkage member 5 , and the sealing ring 6 is located inside the linkage member 5 , and the outer edge of the sealing ring 6 is connected to the inner wall of the linkage member 5 .

[0045] The cylindrical linkage member 5 is convenient for installing the sealing ring 6, and the sliding is more stable. It is also convenient for processing and installation. It can be quickly installed as long as the size is corresponding. At the same time, it can also facilitate the matching of the two sliders 32 and the damping block 51, and the matching state is more stable.

[0046] As an implementation method that can make the sliding of the linkage part 5 more stable, a sliding groove extending along the axial direction of the pen shaft 1 is provided on one side of the inner wall of the linkage part 5 corresponding to the pen shaft 1, and a guide block is provided at the position of the pen shaft 1 corresponding to the sliding groove. The guide block is located in the sliding groove and forms a sliding connection with the sliding groove.

[0047] The cooperation between the slide groove and the guide block can produce a guiding effect, which can make the sliding of the linkage member 5 more stable, and thus make the operation of the cover 4 more stable.

[0048] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
