The conventional selections and substitutions made by those skilled in the art under the guidance of the present invention shall be deemed to be within the scope of protection claimed by the present invention.
[0034] Embodiment 1:
[0035] like Figure 1-Figure 3 As shown, the utility model discloses a point drilling pen for pushing out cement, comprising:
[0036] The pen holder 1 has a length direction along the vertical direction, and the lower end of the pen holder 1 is the tip end of the pen holder 1. A vertically extending clay chamber 11 is provided in the pen holder 1, and the clay chamber 11 can be opened and closed. In addition, a clay outlet 12 is provided in the clay chamber 11 at the tip of the pen holder 1;
[0037] A push member 2, which is movably mounted on the pen holder 1 in a vertical direction;
[0038] Clay block 3, which is in the shape of a long strip;
[0039] When the clay chamber 11 is open, the clay block 3 can be inserted into the clay chamber 11 to complete the arrangement of the clay block 3 in the pen holder 1 , and then the clay block 3 in the clay chamber 11 can be squeezed out from the clay outlet 12 downwardly by the push member 2 .
[0040] Therefore, 1. When the extruded clay is taken multiple times and its viscosity decreases, the unused new clay in the clay chamber 11 is squeezed out by the push piece 2, and the old clay will be discharged simultaneously while the new clay is being squeezed out, so that loading and unloading are carried out simultaneously, and the difficulty of discharging is not affected by the size of the clay outlet 12, making the replacement of clay more convenient; 2. The clay block 3 is built into the clay chamber 11 of the pen shaft 1 to be protected by the pen shaft 1, so that the clay is not easily contaminated by dust and cannot be touched, so as to ensure the viscosity of the unused new clay, 3. The configured clay block 3 is a long strip structure, so that when the clay chamber 11 is in the open state, the long strip clay block 3 can be directly inserted into the clay chamber 11, thereby realizing convenient configuration.
[0041] Specifically, the pen body 1 in this embodiment includes a first rod segment 13 and a second rod segment 14 that are detachably connected, wherein the first rod segment 13 is located below the second rod segment 14, and the first rod segment 13 and the second rod segment 14 are disassembled to open the putty chamber 11, and the first rod segment 13 and the second rod segment 14 are assembled to close the putty chamber 11.
[0042] The detachable manners of the first rod segment 13 and the second rod segment 14 include but are not limited to threaded fit, snap fit, etc.
[0043] Among them, the clay outlet 12 is arranged on the first rod segment 13, and the pushing piece 2 is arranged on the second rod segment 14, so that when the clay chamber 11 is open, the clay block 3 can be placed into the clay chamber 11 part in the first rod segment 13 to prevent the pushing piece 2 from interfering with the clay chamber 11 during the process of placing the clay block 3 into the clay chamber 11. After the clay block 3 is placed, the closing of the clay chamber 11 is completed by cooperating with the first rod segment 13 and the second rod segment 14.
[0044] More specifically, the mud chamber 11 in this embodiment includes a feed chamber 111 and a top chamber 112, and the feed chamber 111, the top chamber 112 and the mud outlet 12 are arranged downward in sequence and connected, and the cross-sectional area of the feed chamber 111 is larger than the cross-sectional area of the top chamber 112, wherein the first rod segment 13 and the second rod segment 14 are disassembled to open the feed chamber 111.
[0045] Therefore, when the first rod segment 13 and the second rod segment 14 are separated, the feed cavity 111 is opened, so that the clay block 3 can be inserted into the feed cavity 111 with a larger cross-sectional area. The clay block 3 can then enter the top cavity 112 which is adapted to the shape of the clay block 3 more smoothly under the action of gravity and the guiding action of the feed cavity 111, and the push piece 2 squeezes the clay in the top cavity 112 with a smaller cross-sectional area, so that the clay can be squeezed out more easily. In addition, the top cavity 112 is not divided, so that the inner circumferential wall of the top cavity 112 is continuously arranged. Under the action of the continuous inner circumferential wall of the top cavity 112, the push piece 2 can push the clay block 3 more completely, thereby preventing the clay from entering the non-continuous gap, resulting in problems such as waste of clay and difficulty in cleaning.
[0046] Preferably, a first transition chamber 113 whose shape gradually decreases from the feeding chamber 111 to the top feeding chamber 112 is provided between the feeding chamber 111 and the top feeding chamber 112 in this embodiment, so that the surrounding wall of the first transition chamber 113 can be used to more smoothly guide the clay block 3 from the feeding chamber 111 with a larger cross-sectional area into the top feeding chamber 112 with a smaller cross-sectional area.
[0047] More preferably, the transition chamber and the feed chamber 111 in this embodiment are tangentially connected, and the transition chamber and the top feed chamber 112 are tangentially connected, so that the guiding smoothness is further improved by utilizing the tangential transition between the feed chamber 111, the first transition chamber 113, and the top feed chamber 112.
[0048] Preferably, a second transition chamber 114 is provided between the top material chamber 112 and the clay outlet 12 in this embodiment, and its shape gradually decreases from the top material chamber 112 to the clay outlet 12, so that the surrounding wall of the second transition chamber 114 can be used to deform the clay block 3 with a larger cross-section into a clay of a size suitable for the clay outlet 12 and squeeze it out for use.
[0049] Among them, the lower end of the pushing member 2 in this embodiment is provided with a top 231, so that the top 231 can squeeze the clay block 3 to squeeze out the clay block 3. Specifically, the outer peripheral shape of the top 231 is adapted to the inner peripheral shape of the feeding cavity 111, and both are cylindrical. Among them, the diameter of the top material cavity 112 is D1, 5mm≤D1≤8mm, and the diameter of the top 231 is D2, 4.9mm≤D2≤7.9mm, so that when the top 231 enters the top material cavity 112, the distance between the outer peripheral wall of the top 231 and the inner peripheral wall of the top material cavity 112 is s=(D1-D2) / 2, s≤0.5mm, and s=0.1mm is preferably selected.
[0050] Therefore, the spacing s is such that there is a certain gap between the inner wall of the top material cavity 112 and the outer wall of the top 231 to ensure the smooth sliding of the top 231 in the top material cavity 112, and the smaller s ensures that when the top 231 pushes the glue downward, it prevents excessive glue from being retained in the top material cavity 112 through the spacing s and causing waste of glue.
[0051] Preferably, the shape of the clay block 3 in this embodiment is cylindrical, and the diameter of the clay block 3 is D3, D3 is slightly smaller than D2, or D3=D2.
[0052] Among them, the pushing member 2 in this embodiment is provided with a screw segment 21, and correspondingly, the inner circumference of the upper end of the second rod segment 14 is provided with an internal thread, so that the pushing member 2 can be inserted into the cement cavity 11 from the upper end of the second rod segment 14, and the threaded installation is realized by the cooperation of the internal thread on the screw segment 21 and the second rod segment 14. Therefore, the pushing member 2 can be rotated so that the pushing member 2 can squeeze the cement downward under the action of the screw segment 21.
[0053] Among them, the pushing member 2 in this embodiment includes a rotating member 22 and a push rod 23, the rotating member 22 and the push rod 23 are respectively located at the upper and lower ends of the screw segment 21, and the three are integrally formed, and the top 231 is integrally formed at the lower end of the push rod 23, wherein the rotating member 22 is located on the outer side of the upper end of the pen body 1, and the push rod 23 is located in the clay cavity 11 of the pen body 1.
[0054] Therefore, the screw segment 21 can be rotated relative to the internal thread on the second segment 14 to achieve spiral lifting by controlling the rotating member 22 to rotate, and during the spiral lifting, the push rod 23 pushes the clay block 3 downward.
[0055] Preferably, the rotating member 22 in this embodiment is in a flat heart shape, wherein the thickness direction of the rotating member 22 is arranged horizontally, so that the flat rotating member 22 can better grasp and rotate, making the rotation more labor-saving, and the heart-shaped rotating member 22 has a decorative effect.
[0056] In addition, a cylindrical metal pen tip 4 is provided at the tip of the pen holder 1 in this embodiment, and the inner diameter of the metal pen tip 4 is D4, D4 ≥ 2.2 mm. Specifically, the size of D4 depends on the size of the diamond and is adjusted according to the actual situation. The thickness of the metal pen tip 4 is d, 0.1 mm ≤ d ≤ 0.15 mm. The metal pen tip 4 has a higher strength to bear the force during the use of the drill pen, and the thinner thickness of the metal pen tip 4 makes the drill pen block a smaller area at the place of use, so that the user can see and operate it more clearly.
[0057] The metal pen tip 4 can be fixed to the pen holder 1 by gluing, hot-melt bonding or the like.
[0058] Preferably, a pen gripping portion 15 is provided on the outer periphery of the first rod segment 13 in the present embodiment, and the pen gripping portion 15 is provided with a plurality of separated pen gripping areas 151 along the circumferential direction, so that the pen gripping posture of the human body can be better adapted through zoning, and the pen gripping is more comfortable and convenient.
[0059] Specifically, a circular ring-shaped lower end limiting portion 152 is provided on the pen holding portion 15 , and a plurality of partition bars 153 are circumferentially provided at the upper end of the lower end limiting portion 152 so as to separate the pen holding areas 151 through the partition bars 153 .
[0060] In addition, an inclined transition surface 154 is provided on the side walls of the lower end limit portion 152 and the partition bar 153, so that the pen holding portion 15 can transition to the lower end limit portion 152 and the partition bar 153 more smoothly, thereby making it more comfortable to hold the pen.
[0061] Embodiment 2:
[0062] like Figure 4 As shown, a point drill pen for pushing out glue has the same main structure as that of the first embodiment, except that the glue block 3 is granular, and the granular glue block 3 can be spherical, cylindrical with a small height, etc.
[0063] Embodiment three:
[0064] like Figure 5As shown, a point drill pen for pushing out glue has a main structure that is the same as that of the first embodiment, except that the glue chamber 11 does not distinguish between a feed chamber 111 and a push chamber 112, the inner circumferential shape of the glue chamber 11 is matched with the outer circumferential shape of the top 231, and the first rod segment 13 and the second rod segment 14 are disassembled to open the upper end of the glue chamber 11.
[0065] or Figure 6 As shown, the first rod segment 13 and the second rod segment 14 are disassembled so that the middle portion of the cement chamber 11 is opened.
[0066] in, Figure 5 compared to Figure 6 The inner circumferential wall of the cement cavity 11 is continuously arranged, so that when the pushing member 2 pushes the cement block 3, the cement block 3 is more smoothly and completely extruded downward under the guidance of the inner circumferential wall of the continuous cement cavity 11.
[0067] Embodiment 4:
[0068] like Figure 7 As shown, a drill pen for pushing out glue has a main structure that is the same as that of the first embodiment, except that the pushing member 2 is not provided with a threaded section. Instead, the pushing member 2 is provided with a sliding section 24 in a cylindrical or polygonal shape, and a through hole that is adapted to the shape and size of the sliding section 24 is provided at the upper end of the second rod section 14, so that the sliding section 24 can slide and fit in the through hole to realize the vertical sliding of the sliding section 24 relative to the pen shaft 1.
[0069] In addition, a plurality of first matching parts 241 are arranged along the length direction on the outer periphery of the sliding section 24 , and the pen body 1 is provided with a second matching part 16 which is engaged with the first matching part 241 , so that positioning is performed by engaging the first matching part 241 with the second matching part 16 .
[0070] Therefore, by pushing the pushing member 2 downward to make it move downward and extrude the glue block 3, and in the pushing process, the first snap-fitting part will forcibly cross the second snap-fitting part, and after the glue is extruded, the pushing of the pushing member 2 is stopped, and the pushing member 2 will limit the vertical movement under the cooperation of the first snap-fitting part and the second snap-fitting part.
[0071] Specifically, the first matching portion 241 is an annular arc-shaped groove, and the second matching portion 16 is an annular arc-shaped protrusion.
