DETAILED DESCRIPTION
[0028] The utility model will be further explained in detail below by combining with the drawings and through the embodiment, the following embodiment is the explanation of the utility model and the utility model is not limited to the following embodiment.
[0029] Referring to Figures 1-7 , the embodiment of a push type pen, including pen barrel 1 and push cap 2, the pen barrel 1 is two-end opening structure, and the cavity of pen barrel 1 is slidably provided with pen core 3, and the bottom end of pen core 3 is provided with spring 31 between pen barrel 1, and the two ends of spring 31 are respectively stopped on the bottom end of pen core 3 and pen barrel 1, and push cap 2 is slidably connected on the top end of pen barrel 1 and cannot rotate, and the side surface of pen barrel 1 is provided with first clamping hole 41 and second clamping hole 42 arranged in sequence along the axial direction of pen barrel 1, and first clamping hole 41 is located above second clamping hole 42, and push cap 2 is provided with elastic strip 5 that can be elastically bent, and elastic strip 5 is provided with clamping block 51 matched with first clamping hole 41 and second clamping hole 42, and the side surface of pen barrel 1 is provided with sliding hole 43 for sliding clamping block 51, and first clamping hole 41 and second clamping hole 42 are communicated through sliding hole 43.
[0030] The top and bottom ends of the first snap-fit hole 41, the top end of the second snap-fit hole 42, and the sides of the top end of the sliding hole 43 are all provided with arc-shaped structures 61. The top and bottom ends of the snap-fit block 51 are provided with first inclined structures 62 at positions opposite to the arc-shaped structures 61. The two first inclined structures 62 are arranged diagonally. The first snap-fit hole 41 is located diagonally above the second snap-fit hole 42. The bottom surface of the snap-fit block 51 is provided with a second inclined structure 63.
[0031] When the pen is in the retracted state of the pen refill 3, the locking block 51 is located inside the first locking hole 41 (e.g., Figure 4 (As shown in the diagram). When the pen refill 3 needs to switch from the retracted state to the extended state, press the snap cap 2 so that the snap cap 2 extends into the pen barrel 1 and pushes the pen refill 3 out of the pen barrel 1. At this time, the spring 31 is compressed, and during this process, the locking block 51 moves along the axial direction of the pen barrel 1 and enters the sliding hole 43 from the first locking hole 41 under the guidance of the arc surface structure 61 at the bottom end of the first locking hole 41 and the first inclined surface structure 62 at the bottom end of the locking block 51. At this time, the elastic strip 5 bends elastically.
[0032] During the sliding of the locking block 51 along the sliding hole 43, when the locking block 51 moves to the connection between the second locking hole 42 and the sliding hole 43, the locking block 51 enters the second locking hole 42 from the sliding hole 43 under the force of the elastic strip 5 returning to its original state, so that the snap cap 2 and the pen barrel 1 are locked, and the pen core 3 on the pen is in the extended state.
[0033] When the pen refill 3 needs to be switched back to the retracted state, press the snap cap 2 again, causing the bottom end of the locking block 51 to abut against the pen barrel 1. Guided by the second inclined structure 63 on the locking block 51, the elastic strip 5 bends towards the snap cap 2, thereby disengaging the locking block 51 from the second locking hole 42 and entering the cavity of the pen barrel 1. The elastic strip 5 then returns to its original state. When the snap cap 2 is stopped, the pen refill 3 extends into the pen barrel 1 under the force of the spring 31 returning to its original state. At the same time, the snap cap 2 extends out of the pen barrel 1 under the push of the pen refill 3. During this process, when the locking block 51 moves to the connection between the cavity of the pen barrel 1 and the first locking hole 41, the force of the elastic strip 5 returning to its original state causes the locking block 51 to enter the first locking hole 41 from the cavity of the pen barrel 1, locking the snap cap 2 and the pen barrel 1. At this time, the pen refill 3 on the pen is in the retracted state.
[0034] As the locking block 51 continues to move after entering the first locking hole 41 from the cavity of the pen barrel 1, when the locking block 51 abuts against the pen barrel 1, the arc surface structure 61 at the top of the first locking hole 41 and the sliding hole 43, together with the first inclined surface structure 62 at the top of the locking block 51, guides the elastic strip 5 to return to its original shape, thereby ensuring the normal use of the pen.
[0035] Referring to Figure 1 , the side of the bottom of the pen barrel 1 is provided with a plurality of finger pinch portions 11 in a recessed manner, each of the finger pinch portions 11 is arranged at an equal angle around the central axis of the pen barrel 1, which ensures the stability of the user holding the pen, improves the control of the pen, and thus ensures the quality of writing.
[0036] Referring to Figure 1 , Figure 2 , the bottom end of the pen barrel 1 is integrally connected with a sharp sleeve 12, which ensures the viewing field of the user when writing.
[0037] Referring to Figure 2 , Figure 3 , the top end of the press cap 2 is provided with a pen clip 7, which facilitates the pen to be carried with the pen clip 7. The top end of the pen clip 7 is provided with a connecting block 72, one end of the connecting block 72 is integrally connected to the pen clip 7 and the other end of the connecting block 72 penetrates through the slot hole 71 and is integrally connected to the side of the press cap 2, which reduces the influence of the setting of the pen clip 7 on the press cap 2 on the sliding of the press cap 2 relative to the pen barrel 1 under pressure.
[0038] Referring to Figures 4-6 , the press cap 2 is provided with a limiting block 8 capable of limiting the bending of the elastic strip 5 towards the press cap 2. When the pen core 3 switches from the retracted state to the extended state, the limiting block 8 can limit the bending direction of the elastic strip 5 during the process of the clamping block 51 entering the sliding hole 43 from the first clamping hole 41, thereby preventing the clamping block 51 from entering the cavity of the pen barrel 1 and affecting the use state switching of the pen core 3, and ensuring the effectiveness of the switching operation of the pen core 3.
[0039] Referring to Figure 5 , Figure 6 , the bottom end of the press cap 2 is provided with a receiving groove 21, and the bottom surface of the press cap 2 is provided with a through hole 22 for the top end of the pen core 3 to penetrate through, the through hole 22 is in communication with the receiving groove 21, which ensures the stability of the press cap 2 driving the pen core 3 to extend out of the pen barrel 1, and the bottom end of the through hole 22 is in the shape of a circular truncated cone 23, which guides the top end of the pen core 3 into the through hole 22.
[0040] Referring to Figures 5-7 , the cavity of the pen barrel 1 is provided with protrusions 91 at two opposite positions, and the side of the press cap 2 is provided with sliding grooves 92 matched with the protrusions 91, which ensures the stability of the sliding of the press cap 2 relative to the pen barrel 1.
