Description

Technical Field

[0001] The utility model relates to a push-type toy pen. Background Art

[0002] Currently, a type of pen with movable toys on the market is very popular among children and young people. For example, a gyroscope pen (CN213261732U) disclosed in a Chinese utility model patent document includes a writing pen body (i.e., a pen holder). A bearing groove is opened on the top of the writing pen body, and a bearing is fixedly connected to the middle part of the inner wall of the bearing groove. The outer ring of the bearing is fixedly connected to a rotating part (i.e., a rotating body). The rotating part is rotatably connected to the writing pen body through the bearing. The user can drive the rotating part to rotate quickly, thereby achieving the effect of playing with the pen and relieving stress, which increases the fun of using the pen.

[0003] In the above-mentioned toy pen, the rotating body is arranged at the rear end of the pen barrel. For a push-type pen, that is, a pen in which the pen core is driven to achieve telescopic movement by an operating component arranged at the rear end of the pen, in order to avoid interference between the rotating body and the operating component of the pen, a through hole needs to be provided in the rotating body so that the operating component can extend backward from the rear end of the rotating body to enable a pressing operation. This imposes certain restrictions on the structure and installation position of the rotating body itself. For example, it must adopt a front-to-back through-structure, and it cannot be arranged at the very rear end of the pen. Since the rotating body and the operating component are relatively independent, the structure is not compact.

[0004] Furthermore, in the aforementioned patent solution, the bearing is simply sleeved into the bearing slot of the writing pen body, and the rotating unit is sleeved and fixed on the outside of the bearing. This connection method utilizes a tight sleeve fit between the components, which requires high precision in the fit between the components. If it is too tight, it will be difficult to assemble the components, while if it is too loose, there will be large gaps between the bearing and the writing pen body, and between the rotating unit and the bearing, which will easily shake or fall off, affecting the stability during use.

[0005] Traditional push-action pens usually include a pen holder, a refill inside the pen holder, a spring, and a telescopic locking mechanism. An operating component is movably provided at the rear end of the pen holder, the telescopic locking mechanism is provided between the rear end of the refill and the operating component, and the spring is provided between the front end of the refill and the pen holder.

[0006] The telescopic locking mechanism usually includes a pressure rod, a guide rail, and a locking member. The pressure rod is connected to the operating member and is driven forward by the operating member. The front end of the locking member cooperates with the pen core support. The guide rail is a plurality of vertical ribs arranged on the inner side of the pen barrel at circumferential intervals. The guide rail is integrally formed on the pen barrel. The pressure rod and the guide rail, as well as the locking member and the guide rail, all form an anti-rotation fit, so that the pressure rod and the locking member can only move along the front and back direction of the pen barrel. When the pressure rod moves forward, it can push the locking member forward, thereby pushing the pen core out, and at the same time making the locking member and the guide rail The anti-rotation cooperation is released, and the locking piece is driven to rotate by the helical teeth at the contact point between the locking piece and the pressure rod piece. When the helical teeth of the locking piece rotate, they are driven by the spring to abut against the front end of the guide rail piece, thereby keeping the locking piece in a state where the pen lead is extended forward; when the pressure rod piece moves forward again, it can push the locking piece forward, causing the locking piece to rotate again. When the spring drives the locking piece to move backward, the front end positions of the locking piece and the guide rail piece change, and the abutment limiting effect is no longer produced, so that the locking piece can move backward a greater distance, allowing the pen lead to be retracted into the pen barrel. Summary of the Invention

[0007] The utility model provides a push-type toy pen, the rear end of which is provided with a rotating body which can be driven to rotate by a user. The rotating body can also be used as an operating component to drive the refill to move in a telescopic manner. The overall structure is compact and has high stability.

[0008] The utility model discloses a push-type toy pen, which includes a pen barrel, a pen core, a spring, and a telescopic locking mechanism. The rear end of the pen barrel is movably provided with an operating mechanism, and the operating mechanism can be driven by hand to move along the axial direction of the pen. The telescopic locking mechanism is arranged between the rear end of the pen core and the operating mechanism, and the spring is arranged between the front end of the pen core and the pen barrel. The telescopic locking mechanism and the operating mechanism are connected, and the pen core can be linked to realize telescopic movement by pressing the operating mechanism. The operating mechanism includes a connecting sleeve, a rotating sleeve, a rotating body, and a bearing, wherein the connecting sleeve is connected to the telescopic locking mechanism, the front end of the connecting sleeve is movably sleeved on the outer side of the rear end of the pen barrel, the rotating sleeve is arranged on the outer side of the rear end of the connecting sleeve, and the rotating body is arranged at the rear end of the rotating sleeve. The connecting sleeve and the rotating sleeve form a circular cavity, and the bearing is arranged in the cavity. The arrangement of the bearing can reduce the friction between the rotating sleeve and the connecting sleeve during relative rotation, and improve the rotation effect of the rotating body. The rear end of the connecting sleeve includes a convex column that is engaged with the inner ring of the bearing. The connecting sleeve has a first annular step surface at the root of the convex column, and the first annular step surface constitutes the front side wall of the cavity. The inner hole of the rotating sleeve is engaged with the outer ring of the bearing, and the inner side of the rotating sleeve has a second annular step surface, and the second annular step surface constitutes the rear side wall of the cavity. The bearing sleeve is arranged on the convex column, and the first annular step surface and the second annular step surface are used to achieve limited fit with the front and rear sides of the bearing, which can reduce the shaking of the bearing and improve the installation effect of the bearing.

[0009] Furthermore, the rotating body and the rotating sleeve are two separately arranged components, and the rotating body and the rotating sleeve form an axial plug-in positioning fit, which makes assembly more convenient. This also enables the rotating body to be produced and processed separately, and the variety of toy pens can be enriched by configuring rotating bodies of different shapes.

[0010] Furthermore, the rotating body has a plurality of blades evenly distributed along the circumference of its rotating axis, so that the rotating body can be rotated by airflow. When the user blows air at the rotating body with his mouth, the rotating body can also be driven to rotate, thereby increasing the fun of the toy pen.

[0011] Furthermore, the rear end of the pen shaft is provided with an opening, and the rear end of the pressure rod of the telescopic locking mechanism extends backward from the opening at the rear end of the pen shaft, and forms an axial plug-in positioning fit with the center hole of the boss, thereby realizing the connection and fit between the connecting sleeve and the telescopic locking mechanism. When the connecting sleeve is driven to move axially forward, it can also push the pressure rod to move forward.

[0012] Further, the first annular step surface includes a first annular mating surface and a first annular recess, the first annular recess is arranged at the radially outer position of the first annular mating surface, the first annular mating surface is abutted and limited with the inner ring of the bearing, and the first annular recess is arranged at a position corresponding to the outer ring of the bearing; the second annular step surface includes a second annular mating surface and a second annular recess, the second annular recess is arranged at the radially outer position of the second annular mating surface, the second annular mating surface is abutted and limited with the outer ring of the bearing, and the second annular recess is arranged at a position corresponding to the inner ring of the bearing.

[0013] In the above scheme, the first annular mating surface and the second annular mating surface are respectively abutted and limited with the front end of the inner ring of the bearing and the rear end of the outer ring, thereby improving the positioning effect of the bearing and reducing the shaking of the bearing. The first annular recess and the second annular recess are respectively arranged at the corresponding positions of the front end of the outer ring of the bearing and the rear end of the inner ring. This can first avoid contact between the first annular step surface and the outer ring of the bearing, and between the second annular step surface and the inner ring of the bearing, thereby reducing friction. The inner and outer rings of the bearing can also give way when they move axially relative to each other, thereby improving the operation effect of the bearing.

[0014] Furthermore, the outer side of the rear end of the pen barrel includes an annular notch, and the front end of the connecting sleeve is movably arranged at the notch at the rear end of the pen barrel. The setting of the notch helps to reduce the width of the toy pen (at the connecting sleeve), making the structure of the toy pen more compact and beautiful.

[0015] Furthermore, the rotating sleeve includes a connecting hole that rotates with the boss at the rear end of the connecting sleeve. The connecting hole is provided with an opening at the rear end of the rotating sleeve. The end of the boss includes a limiting portion that axially limits the boss and the rear end of the rotating sleeve, thereby preventing the boss from falling out of the connecting hole of the rotating sleeve.

[0016] Furthermore, the boss includes at least two elastic claw arms uniformly spaced along the circumference of its axis, and there is a gap between the elastic claw arms for them to deform and shrink toward the center of the boss. The outer sides of the ends of the elastic claw arms are provided with the limiting parts, and the limiting parts are wedge-shaped blocks. When the boss is inserted and installed along the connecting hole, the wedge-shaped blocks cause these elastic claw arms to deform and shrink toward the axis, thereby facilitating the insertion of the boss. When the wedge-shaped blocks are extended along the opening, these elastic claw arms expand and reset under their own elastic action, so that the wedge-shaped blocks and the rear end of the connecting sleeve form a limiting fit, which facilitates the assembly of the connecting sleeve and the rotating body.

[0017] The beneficial effects of this utility model are as follows: the rotating body at the rear end of the push-action toy pen can be driven by the user's hand or by blowing air, providing a playful and stress-relieving effect, thereby enhancing the fun of the toy pen. Furthermore, the rotating body is an integral part of the operating mechanism; by pressing the rotating body, the user can drive the toy pen's refill to extend and retract. Compared to existing technologies, the toy pen has a more compact and aesthetically pleasing structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The embodiment of the utility model of the push-type toy pen is as follows: Figure 1-6 As shown: it includes a pen body 1, a pen core 2, a spring 3, and a telescopic locking mechanism are arranged inside the pen body 1, an operating mechanism is movably arranged at the rear end of the pen body 1, and the operating mechanism can be driven by hand to move along the axial direction of the pen, the telescopic locking mechanism is arranged between the rear end of the pen core 2 and the operating mechanism, the spring 3 is arranged between the front end of the pen core 2 and the pen body 1, the telescopic locking mechanism and the operating mechanism are connected, and the pen core 2 can be linked to realize telescopic movement by pressing the operating mechanism.

[0027] The specific structure and principle of the telescopic locking mechanism are relatively common in existing push-type pens and belong to the existing technology. The telescopic locking mechanism usually includes a pressure rod 41, a guide rail 42, and a locking member 43. The pressure rod 41 is connected to the operating mechanism and is driven forward by the operating mechanism. The front end of the locking member 43 is supported and matched with the pen core 2. The guide rail 42 is a plurality of vertical ribs arranged on the inner side of the pen body 1 at intervals in the circumference. The guide rail 42 is integrally formed on the pen body 1. The pressure rod 41 and the guide rail 42 as well as the locking member 43 and the guide rail 42 all form an anti-rotation fit, so that the pressure rod 41 and the locking member 43 can only move along the front and back direction of the pen body 1. When the pressure rod 41 moves forward, it can push the locking member 43 forward, thereby pushing the pen core 2 out, and at the same time making the locking member 43 and The anti-rotation cooperation of the guide member 42 is released, and the helical teeth at the contact point of the locking member 43 and the pressure rod member 41 are used to drive the locking member 43 to rotate. After the helical teeth of the locking member 43 rotate, they are driven by the spring 3 to abut against the front end of the guide member 42, thereby keeping the locking member 43 in a state where the pen core 2 is extended forward; when the pressure rod member 41 moves forward again, it can push the locking member 43 to move forward, causing the locking member 43 to rotate again. When the spring 3 drives the locking member to move backward, due to the change in the front end position of the locking member 43 and the guide member 42, the abutment limiting effect is no longer produced, so that the locking member 43 can move backward a greater distance, allowing the pen core 2 to be retracted into the pen body 1.

[0028] The operating mechanism includes a connecting sleeve 51, a rotating sleeve 52, a rotating body 53, and a bearing 54, wherein the connecting sleeve 51 is connected to the telescopic locking mechanism, the front end of the connecting sleeve 51 is movably sleeved on the outer side of the rear end of the pen barrel 1, the rotating sleeve 52 is rotatably sleeved on the outer side of the rear end of the connecting sleeve 51, and the rotating body 53 is arranged at the rear end of the rotating sleeve 52. A circular chamber 50 is formed at the sleeve joint of the connecting sleeve 51 and the rotating sleeve 52, and the bearing 54 is arranged in the chamber 50. The arrangement of the bearing 54 can reduce the friction between the rotating sleeve 52 and the connecting sleeve 51 during relative rotation, improve the rotation effect of the rotating body 53, and the rear of the connecting sleeve 51 The end includes a boss 511 that cooperates with the inner ring 54a of the bearing 54. The connecting sleeve 51 has a first annular step surface at the root of the boss 511 (that is, the front end corresponding to the direction of the pen tip). The first annular step surface constitutes the front side wall of the chamber 50. The inner hole of the rotating sleeve 52 cooperates with the outer ring 54b of the bearing 54. The inner side of the rotating sleeve 52 has a second annular step surface, and the second annular step surface constitutes the rear side wall of the chamber 50. The bearing 54 is sleeved on the boss 511, and the first annular step surface and the second annular step surface are used to achieve limited fit with the front and rear sides of the bearing 54, which can reduce the shaking of the bearing 54 and improve the installation effect of the bearing 54.

[0029] The rotating body 53 and the rotating sleeve 52 are two separate components. They form an axially pluggable and positioned fit, making assembly easier. This reduces the difficulty of manufacturing the rotating body 53 and allows the rotating body 53 to be manufactured separately. By configuring rotating bodies 53 of different shapes, the variety of toy pens can be expanded. In other embodiments, the rotating body 53 and the rotating sleeve 52 can also be integrally formed.

[0030] In this embodiment, if Figures 1 to 4 As shown, the rotating body 53 adopts a regular wheel-shaped structure and has good stability when rotating. Figure 7 、 8 As shown, the rotating body 53 has a plurality of blades 531 evenly distributed along the circumference of its rotating axis, so that the rotating body 53 can be rotated by air flow. When the user blows air at the rotating body 53 with his mouth, the rotating body 53 can also be driven to rotate, thereby increasing the fun of the toy pen.

[0031] like Figure 4 As shown, the rear end of the pen shaft 1 is provided with an opening 10, and the rear end of the pressure rod 41 of the telescopic locking mechanism extends backward from the opening 10 at the rear end of the pen shaft 1, and forms an axial plug-in positioning fit with the center hole of the boss 511, thereby realizing the connection and fit between the connecting sleeve 51 and the telescopic locking mechanism. When the connecting sleeve 51 is driven to move axially forward, it can also push the pressure rod 41 to move forward.

[0032] like Figure 5 As shown, the first annular step surface includes a first annular mating surface 5121 and a first annular recess 5122, the first annular recess 5122 is arranged at the radially outer position of the first annular mating surface 5121, the first annular mating surface 5121 is abutted and limited with the inner ring 54a of the bearing 54, and the first annular recess 5122 is arranged at a position corresponding to the outer ring 54b of the bearing 54; the second annular step surface includes a second annular mating surface 5131 and a second annular recess 5132, the second annular recess 5132 is arranged at the radially outer position of the second annular mating surface 5131, the second annular mating surface 5131 is abutted and limited with the outer ring 54b of the bearing 54, and the second annular recess 5132 is arranged at a position corresponding to the inner ring 54a of the bearing 54.

[0033] In the above scheme, the first annular mating surface 5121 and the second annular mating surface 5131 are respectively abutted and limited with the front end of the inner ring 54a and the rear end of the outer ring 54b of the bearing 54, thereby improving the positioning effect of the bearing 54 and reducing the shaking of the bearing 54. The first annular recess 5122 and the second annular recess 5132 are respectively arranged at the corresponding positions of the front end of the outer ring 54b and the rear end of the inner ring 54a of the bearing 54. This can first avoid contact between the first annular step surface and the outer ring 54b of the bearing and between the second annular step surface and the inner ring 54a of the bearing, thereby reducing friction. The inner and outer rings of the bearing 54 can also give way when they move axially relative to each other, thereby improving the operation effect of the bearing 54.

[0034] The outer side of the rear end of the pen body 1 includes an annular notch 11. The front end of the connecting sleeve 51 is movably set at the notch 11 at the rear end of the pen body 1. The setting of the notch 11 helps to reduce the width of the toy pen (the width at the connecting sleeve 51), making the structure of the toy pen more compact and beautiful.

[0035] The rotating sleeve 52 includes a connecting hole that rotates with the boss 511 at the rear end of the connecting sleeve 51. The connecting hole is provided with an opening 521 at the rear end of the rotating sleeve 52. The end of the boss 511 includes a limiting portion 514 that forms an axial limiting fit with the rear end of the rotating sleeve 52, which can prevent the boss 511 from falling out of the connecting hole of the rotating sleeve.

[0036] The boss 511 is composed of two elastic claw arms 511a spaced evenly along its axis. A gap exists between the elastic claw arms 511a, allowing them to deform and contract toward the center of the boss 511. The ends of the elastic claw arms 511a are each provided with a stopper 514, a wedge-shaped block. When the boss 511 is inserted and installed through the connecting hole, the wedge blocks cause the elastic claw arms 511a to deform and contract toward the axis, thereby facilitating the insertion of the boss 511. When the wedge blocks extend through the opening, the elastic claw arms expand and return to their original position under their own elastic action, forming a stoppered fit between the wedge blocks and the rear end of the connecting sleeve 51, thereby facilitating the assembly of the connecting sleeve 51 and the rotating body 53. In other embodiments, a greater number of elastic claw arms 511a may also be provided.

[0037] The above embodiment is only one preferred embodiment of the present invention. Common changes and substitutions made by those skilled in the art within the scope of the technical solution of the present invention are all included in the protection scope of the present invention.
