Description

Technical Field

[0001] The invention belongs to the field of daily necessities, and in particular relates to a writing tool with a sealing device. Background Art

[0002] With the continuous improvement of living standards, we can usually see different kinds of writing tools in office areas. After using the writing tools, in order to prevent the ink inside from being exposed to the air and affecting the writing effect, high requirements are often placed on the sealing device. In the prior art, most writing tools only retract the pen core into the pen case after use. The writing tools lacking sealing devices cause the ink to leak or evaporate easily. Even if the writing tools are provided with sealing devices, the sealing devices often fail to completely isolate the pen core from the external environment, resulting in the loss of ink, thereby affecting the smoothness of the writing of the pen core. In view of this, it is necessary to design a writing tool with a sealing device. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a writing tool with a sealing device in view of the current status of the prior art.

[0004] The technical solution adopted by the present invention to solve the above technical problems is: to provide a writing tool with a sealing device, comprising: a pen shell and a pen core arranged in the pen shell, and also comprising:

[0005] A rotating shield is movably disposed in the pen housing and close to the outlet end of the pen housing;

[0006] A sealing block, which movably abuts against the rotating shield, and one end of the sealing block is connected to a tightening spring;

[0007] A moving assembly is arranged in the pen housing and connected to the pen core, and a moving plate is provided on the moving assembly, one end of the moving plate is movably connected to the rotating shielding plate, and the other end of the moving plate is fixedly connected to the holding spring;

[0008] When the movable plate moves, the rotating shield plate can be driven to rotate, and when the rotating shield plate reaches a preset position, the pen core can extend out of the pen housing.

[0009] In the above-mentioned writing tool with a sealing device, mounting blocks are symmetrically arranged in the pen housing, mounting posts are symmetrically arranged on the rotating shield, and the mounting posts are movably abutted against the mounting blocks.

[0010] In the above-mentioned writing tool with a sealing device, a fixed block is provided on the rotating shield plate, a mounting groove is formed in the fixed block, and a switch block is provided at the end of the movable plate, and the switch block is used to extend into the mounting groove.

[0011] In the above-mentioned writing tool with a sealing device, a limiting block is arranged in the pen housing, and a protruding block is arranged on the sealing block, and the protruding block abuts against the limiting block.

[0012] In the above-mentioned writing tool with a sealing device, an ink storage shell is movably provided on the moving component, and a compression spring is connected between the ink storage shell and the moving plate.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] (1) The rotating shutter can abut against the sealing block when not opened, preventing the ink loss caused by the contact between the pen core and the outside air, thereby ensuring the smoothness of writing after the pen core is extended out of the pen housing;

[0015] (2) One end of the sealing block is connected to a pressing spring, which can give the sealing block a force against the rotating shield, thereby ensuring that the sealing block and the rotating shield are tightly fitted, thereby making the writing tool have better sealing performance;

[0016] (3) The mounting grooves formed in the movable plate and the fixed block can realize the opening and closing of the rotating shutter, which is convenient for the use of the writing tool and can also ensure that the rotating shutter isolates the pen core from the external environment;

[0017] (4) A compression spring is connected between the ink storage housing and the movable plate. When the ink storage housing moves, the compression spring can provide a buffering force to the movable plate, thereby opening the rotating shutter, thereby ensuring smoothness when the writing tool is used;

[0018] (5) Compared with the sealing device in the prior art, the rotating shutter in the present invention can be opened and closed by only pushing the fixed block on the rotating shutter. The structure is relatively simple and the manufacturing cost is low. The rotation and sealing effects can ensure that the ink will not be lost, thereby improving the economic benefits brought by the writing tool. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0026] like Figures 1 to 5 As shown, a writing tool with a sealing device comprises: a pen case 1 and a pen core 2 arranged in the pen case 1, and also comprises: a rotating shield plate 3, which is movably arranged in the pen case 1 and close to the outlet end of the pen case 1; a sealing block 4, which movably abuts against the rotating shield plate 3, and one end of the sealing block 4 is connected to a tightening spring 5; a moving component, which is arranged in the pen case 1 and connected to the pen core 2, and a moving plate 6 is provided on the moving component, one end of the moving plate 6 is movably connected to the rotating shield plate 3, and the other end of the moving plate 6 is fixedly connected to the tightening spring 5; when the moving plate 6 moves, it can drive the rotating shield plate 3 to rotate, and when the rotating shield plate 3 reaches a preset position, the pen core 2 can extend out of the pen case 1.

[0027] The rotating shutter 3 is located near the outlet end of the pen case 1, and the sealing block 4 movably abuts against the rotating shutter 3. One end of the sealing block 4 is connected to a tightening spring 5, which is used to ensure that the sealing block 4 always abuts against the rotating shutter 3, thereby improving the sealing performance of the pen core 2 when not in use, and ensuring the smoothness of the pen core 2 when writing. Because the rotating shutter 3 is movably arranged in the pen case 1, the movable plate 6 in the movable assembly is required to drive the rotating shutter 3 to rotate. Therefore, when the writing tool is not in use, the rotating shutter 3 and the sealing block 4 abut against each other, thereby isolating the pen core 2 in the movable assembly from the external environment. When the movable plate 6 drives the rotating shutter 3 to rotate and reaches the preset position, the movable assembly can extend the pen core 2 out of the pen case 1 for writing.

[0028] A mounting block 7 is symmetrically arranged in the pen housing 1 , and a mounting column 8 is symmetrically arranged on the rotating shielding plate 3 , and the mounting column 8 is movably pressed against the mounting block 7 .

[0029] The mounting block 7 symmetrically arranged in the pen housing 1 is used to install the rotating shield 3. The rotating shield 3 is symmetrically provided with mounting columns 8. The mounting block 7 is provided with a mounting arc surface. The mounting columns 8 can be movably abutted against the mounting arc surface, thereby ensuring that the movable plate 6 drives the rotating shield 3 to rotate on the mounting arc surface.

[0030] A fixing block is provided on the rotating shield plate 3 , and a mounting groove 9 is formed in the fixing block. A switch block 10 is provided at the end of the movable plate 6 , and the switch block 10 is used to extend into the mounting groove 9 .

[0031] A mounting groove 9 is formed in the fixed block on the rotating shutter 3, and the switch block 10 at the end of the movable plate 6 extends into the mounting groove 9, thereby ensuring that the movable plate 6 can drive the rotating shutter 3 to rotate when it moves. It should be noted that the fixed block includes an opening fixed block 11 and a closing fixed block 12, and the end of the opening fixed block 11 is provided with a transition arc surface 13, and a sealing plane 14 and a locking arc surface are provided on the rotating shutter 3. An arc-shaped limiting surface 16 is provided at a position close to the outlet end of the pen shell 1. When the movable plate 6 pushes the opening fixed block 11, the rotating shutter 3 will rotate around the axis of the mounting column 8. When it rotates to a certain angle, the locking arc surface will abut against the pen On the arc limiting surface 16 on the shell 1, the rotating shutter 3 stops rotating at this time, and because the moving block still has the force to drive forward, the switch block 10 will stop after passing through the transition arc surface 13 and leaving the mounting groove 9 for a distance. The design of the transition arc surface 13 ensures that there will be no interference between the switch block 10 and the opening fixed plate when the two move. After use, it is necessary to retract the pen core 2 and reset the rotating shutter 3. The moving plate 6 moves by pushing the closing fixed block 12, thereby driving the rotating shutter 3 to rotate. When the moving plate 6 reaches the initial position, the sealing plane 14 on the rotating shutter 3 will also seal the pen core 2 again.

[0032] A limiting block 17 is arranged in the pen housing 1 , and a protruding block 18 is arranged on the sealing block 4 , and the protruding block 18 abuts against the limiting block 17 .

[0033] When the rotating shutter 3 is in a sealed state, the pressing spring 5 will make the sealing block 4 press against the rotating shutter 3. It should be noted that when the rotating shutter 3 is in a sealed state, the sealing plane 14 on the rotating shutter 3 presses against the side of the sealing block 4 close to the outlet end of the pen shell 1, and under the pressing effect of the pressing spring 5 on the sealing block 4, the sealing block 4 and the rotating shutter 3 completely seal the pen core 2 in the moving component, ensuring that the ink will not contact with the outside and cause outflow, and the raised block 18 on the sealing block 4 and the limit block 17 on the pen shell 1 are to ensure that during the movement of the moving component, the sealing block 4 is prevented from moving to the inside of the rotating shutter 3, and the rotating shutter 3 placed horizontally with the sealing block 4 and the limit block 17 presses against each other to achieve a good sealing effect.

[0034] An ink storage housing 19 is movably provided on the moving component, and a compression spring 20 is connected between the ink storage housing 19 and the moving plate 6 .

[0035] The end of the ink storage shell 19 is connected to the pen core 2, and a compression spring 20 is provided between the ink storage shell 19 and the movable plate 6. When the ink storage shell 19 is squeezed and moves, a compression force is applied to the compression spring 20, and then the compression spring 20 applies a driving force to the movable plate 6, so that the movable plate 6 drives the rotating shutter 3 to rotate and open during the movement. When the rotating shutter 3 reaches the preset position, the ink storage shell 19 is not yet in the preset position, so it still needs to move forward until it drives the pen core 2 to extend out of the pen shell 1.

[0036] It should be noted that the process of extending and retracting the refill 2 in the present invention is consistent with the prior art and does not fall within the scope of protection of the present invention. The main part of the present invention lies in the sealing device designed for the refill 2 of the writing tool, so that the refill 2 can achieve good sealing when not in use.

[0037] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0038] In addition, in the present invention, descriptions such as "first", "second", "one", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0039] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.
