Referring to fig. 1-13, the pressing pen of the present embodiment includes a barrel 1, a pressing portion 2 and a refill 3, where the pressing portion 2 is connected with the refill 3 to realize that the refill 3 stretches back and forth in the barrel 1, and a cap 4 is movably turned over at the front end or the rear end of an opening 1001 of a nib 10 of the barrel 1, so that an initial position of the cap 4 is attached to an end face of a cavity end under an unstressed condition, and a cavity of the barrel 1 at the rear end of the cap 4 is sealed relatively.
The pressing part 2 presses forward to the pen holder barrel 1, so that the pen core 3 is driven to push the cap 4 open the opening 1001 of the pen point 10; the pressing part 2 rebounds reversely towards the pen holder barrel 1 to drive the pen core 3 to retract into the cavity of the rear end of the cap 4 of the pen holder barrel 1.
The pen holder barrel 1 is cylindrical, a circular cavity corresponding to the pen core 3 is arranged in the pen holder barrel, one end of the cavity is connected with the opening 1001 of the pen point 10, the other end of the cavity is connected with the pressing part 2, and when a user needs to use the pen, the pen core 3 can be driven to move forwards along the cavity by pressing the pressing part 2 with the thumb, and the cap 4 is pushed open to extend out of the opening 1001 of the pen point 10; when a user does not need to use a pen, the pressing part 2 can be pressed again, and the pen is similar to a common pressing pen in structure, the pen core 3 is driven to move backwards along the cavity through the telescopic locking mechanism, the pen core is retracted into the cavity of the rear end of the pen holder barrel 1 at the back end of the cap 4, meanwhile, the pen core is attached to the end part of the cavity of the pen holder barrel 1 through the cap 4 to form a relatively sealed state, the head end of the pen core 3 is protected, the air drying of the pen core 3 can be effectively prevented, the service life of the pen core 3 is prolonged, the pen core 3 can adopt a neutral pen, a marking pen, a mark pen and the like, and the air drying prevention effect can be realized through the structure.
One end of the cap 4 is hinged to the side wall of the cavity end, the movable overturning of the cap 4 is set in a coil spring 5 mode or in a magnetic adsorption mode, and the two setting conditions are contained according to the difference of the setting positions of the cap 4:
Setting mode one: the cap 4 is arranged at the front end of the pen point 10, and the movable overturning structure of the cap 4 is formed by magnetically adsorbing the inner side end surface of the cap 4 and the end surface of the opening 1001 of the pen point 10. The position of the cap 4 is at the end of the opening 1001 of the nib 10, as shown in fig. 3, the pen core 3 is driven by the pressing part 2 to eject the cap 4 and contact with the cap 4 through the side part of the pen core 3 to fully eject one side, at this time, the head end of the nib 10 extends out to be higher than the end part of the cap 4, in this embodiment, the end surface of the opening 1001 of the nib 10 is in an inclined surface, and the movable turnover structure of the cap 4 adopts the magnetic adsorption of the inner end surface of the cap 4 and the end surface of the opening 1001 to perform the covering or adopts the connection mode of resetting the cap 4 through the coil spring 5 to perform the covering;
Setting mode II: the cap 4 set up in the vice cavity 1011 of trompil 1001 rear end of nib 10, the activity flip structure of cap 4 adopt the inboard terminal surface of cap 4 to pass through magnetism absorption lid with cavity outside terminal surface and close (specifically be provided with little magnet at the inboard terminal surface of cap 4, be provided with annular magnet at the first barrel 101 inside wall that is close to the top of cap 4), cap 4 set up in the vice cavity 1011 of trompil 1001 rear end of nib 10, as shown in fig. 6, at this moment, activity flip structure can adopt the outside terminal surface of cap 4 and the lateral wall face of vice cavity 1011 in the side of cap 4 expansion to reset through magnetism repulsion setting or with cap 4 through coil spring 5 connected mode and carry out the lid and close.
Further, in order to obtain a larger overturning restoring force of the cap 4, a magnet may be disposed on a side wall surface of the sub-cavity 1011 on the deployment side of the cap 4, and the magnet is disposed to magnetically repel the outer side end surface of the cap 4. The proposal is only a technical proposal with more optimized effect, but can also cause side effect of higher cost, and can be selected to be used or not used according to actual needs.
Further, the end of the refill 3 is magnetically repulsive to the inner end surface of the cap 4, and the end of the refill 3 is adjacent to the end of the cap 4, the repulsive force is larger than the restoring force of the cap 4 to the end surface of the cavity in the initial state (the restoring force refers to the force of the cap 4 being attached to the end surface of the cavity in the unstressed state, and the force can be provided by the coil spring 5 or magnetic attraction), if the coil spring 5 is adopted, the restoring force is the elastic force of the coil spring 5 and is proportional to the rigidity and the deformation of the coil spring 5, and if the magnetic attraction is adopted, the restoring force is the attractive force between the magnets and is inversely proportional to the magnetism and the distance of the magnets.
In the above-mentioned propping-up mode, the head end of the pen core 3 is generally propped up by contacting the cap 4, and the long-term use may shorten the service life of the head end of the pen core 3, and oil leakage or incapability of writing occurs, so the embodiment provides the following modes: based on two setting positions of the cap 4, an annular magnet is sleeved on the head end of the pen core 3, the annular magnet repels with a small magnet arranged on the inner end surface of the cap 4, the head end of the pen core 3 is close to the end part of the cap 4, and the repulsive force is larger than the elastic force of the coil spring 5 or the repulsive force of the cap 4 and the side wall surface of the auxiliary cavity 1011, so that the repulsive force generated between the annular magnet and the small magnet sets up to enable the head of the pen core 3 to push the cap 4 to the side part to turn over the angle after the pen core 3 is not contacted with the cap 4, and then the side part of the pen core 3 (namely the position of the magnetic part 6) is contacted with the cap 4 to continuously push the cap 4 to be turned over until the pen core 3 stretches out of the opening 1001 of the pen point 10, as shown in fig. 3-5 (which shows the working principle of the first setting mode of the cap 4), and fig. 6-8 (which shows the working principle of the first setting mode of the cap 4).
It should be noted that, in fig. 3-8, the arrangement of the coil spring 5 and the magnet (the source of restoring force) is shown (in which the magnet is covered by a shadow or filled by a blank), and the coil spring and the magnet may be selected in the actual production process. Thus, according to the arrangement mode (arrangement mode one or arrangement mode two) of the cap 4 and the source of restoring force (rebound of the coil spring 5 or magnetic attraction of the magnet), four different kinds of pressing pens can be manufactured for distinguishing: matching one: the cap 4 is arranged in a mode of one spring 5 rebound; collocation II: the cap 4 is selected to be provided with a second mode and is magnetically attracted by a magnet; and (3) matching three: the cap 4 is arranged in a second mode and the coiled spring 5 rebounds; and (4) matching: the cap 4 is arranged in a mode of two+magnetic attraction of the magnet.
The repulsive force of the head of the pen core 3 is obtained by adopting the magnetic piece 6, the pen core 3 is driven by the pressing part 2 to move downwards, under the action of repulsive force, the cap 4 is turned to the side part by a part angle under the condition of not contacting the cap 4, and then the cap 4 is continuously pushed up by the side part of the pen core 3 to be turned over until the pen core 3 stretches out of the opening 1001 of the pen point 10.
