Description

Technical Field

[0001] The present invention relates to the technical field of stationery products, and in particular to a pull-out and replacement mechanism and a stationery product containing the same. Background Art

[0002] Currently, stationery items that can be stored by pressing a button include correction tape, adhesive tape, or automatic ballpoint pens. For example, the invention patent with the authorization announcement date of January 18, 2006 and the authorization announcement number CN2752073 discloses a button-type storage for correction tape, which includes a back cover, a front cover, and a tape holder. A button is provided at one end of the back cover, a fixing member is fixed inside the back cover, and a back member and a front member are provided at the other end of the button. The back member and the front member are sequentially inserted into the fixing member. One end of the front member pushes a correction tape device provided inside the front cover. One end of the correction tape device is provided with a correction tape applicator, and a spring is provided inside the correction tape device. This button-type storage for correction tape is achieved by the interaction of the button, the back cover, the fixing member, the back member, the front member, and the spring provided inside the correction tape device. Pressing the button for the first time causes the correction tape on the applicator to extend outward from the end of the front cover for use. Pressing the button again causes the applicator with the correction tape to retract into the front cover. When the correction tape device is used up and needs to be replaced, it is necessary to first release the buckle between the rear cover and the front cover, then open the rear cover, take out the used correction tape device from the front cover, then place the new correction tape device into the front cover, and fit the front end of the front piece onto the protrusion on the new correction tape device, and finally buckle the rear cover onto the front cover.

[0003] This type of button-type correction tape storage requires disassembly of the back cover and the front cover to replace the correction tape, which is a cumbersome operation. In addition, the components that constitute the press-and-retract mechanism are usually disassembled and installed in the back cover and the correction tape, and the press-and-retract function is limited by the correction tape; the back part and the front part are usually detachable and installed in the back cover and the button, and they may fall off and be lost due to external force; the spring is usually set in the correction tape that is frequently replaced, which increases the cost of use and also causes unnecessary waste of resources; the spring compression plate and the tape fixing part need to be limited in the pressing direction, otherwise the correction tape may easily be displaced during the pressing process and cause a malfunction, so the spring compression plate usually needs to be engaged with the tape fixing part so that the pressing process is limited, and its structure is usually difficult to assemble. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a pull-out and replacement mechanism and a stationery product containing the pull-out and replacement mechanism. The pull-out mechanism and the stationery product containing the pull-out and replacement mechanism have modular functions, integrated structures, simple and efficient assembly, and convenient and quick replacement.

[0005] In order to solve the above technical problems, the technical solutions adopted by the present invention are as follows:

[0006] A pulling and replacing mechanism, characterized by comprising:

[0007] The accommodating member comprises an accommodating portion, a clutch portion and a locking portion; the accommodating portion comprises an accommodating space for accommodating the functional core member;

[0008] The carrying portion is located in the receiving member and is used to accommodate and carry the functional core member;

[0009] The clutch member has a clamping portion, and the clutch member and the accommodating member are temporarily engaged and fixed through the clamping portion and the locking portion;

[0010] The connecting member is arranged between the clutch member and the accommodating member. The clutch member, the connecting member and the accommodating member together constitute a pull-out assembly. The connecting member and the accommodating member can move relative to each other and can limit the range of movement. The clutch member and the clutch part can move relative to each other and are restricted by the connecting member. A replaceable opening is formed between the connecting member, the clutch member and the accommodating member, the size of the opening of which can be adjusted by pulling.

[0011] After the above-mentioned components are assembled, the above-mentioned connecting piece is movable between the clutch piece and the accommodating piece, and the clutch piece and the connecting piece, as well as the connecting piece and the accommodating piece, are not removable, so that the clutch piece and the accommodating piece are connected through the connecting piece to form a pull-out assembly that is movable and non-detachable after the assembly is completed, and a replaceable opening is formed whose opening size can be adjusted by pulling.

[0012] The clutch component and the clutch portion of the accommodating component are capable of relative movement and are restricted by the connecting component, and the connecting component can be movably pulled and drawn relative to the accommodating component, so that the size of the replacement opening is changeable; when the functional core component is to be replaced, the temporary fixation between the clutch component and the accommodating component is released, the replacement opening becomes larger, and the functional core component will not be restricted by the edge of the replacement opening, so that the functional core component can be easily installed in the load-bearing part or removed from the replacement opening through the replacement opening; when the clutch component and the accommodating component are temporarily fixed, the replacement opening becomes smaller, and the functional core component is restricted by the edge of the replacement opening, so that the functional core component cannot be removed from the replacement opening, so that the functional core component can be firmly installed in the load-bearing part of the accommodating component.

[0013] In a preferred embodiment, the bearing portion is provided with a placement location, and the functional core member is detachably mounted in the placement location; the bearing portion is disposed on the connecting member or the clutch member. Since the bearing portion is disposed on the connecting member or the clutch member, and the functional core member is disposed on the bearing portion, when the connecting member or the clutch member is withdrawn or pulled, the functional core member can be withdrawn or pulled along with the connecting member or the clutch member within the accommodating member.

[0014] Generally, the above-mentioned functional core parts generally refer to replaceable components with specific functions and complete and independent structures, such as replacement pen cores, replacement tape cores, correction tape cores, tape cores, etc. When the functional core parts need to be replaced, the temporary fixation between the engaging portion of the clutch and the locking portion of the accommodating portion can be released first, and the clutch can be pulled out of the accommodating portion, and then a new functional core part can be replaced through the replacement opening for use. This pull-out replacement mechanism is very convenient and fast to replace, and the functional components are connected as one, so that the pull-out replacement mechanism can be reused by replacing relatively cheap and lightweight functional core parts, which saves resources and costs to a certain extent, and can be applied to frequently consumed stationery products such as transfer utensils or writing utensils.

[0015] The present invention also provides a stationery product containing the above-mentioned pull-out and replacement mechanism, which is characterized in that: it includes a functional core member, a telescopic mechanism and the above-mentioned pull-out and replacement mechanism; the telescopic mechanism is movably arranged in the clutch member, and the connecting member abuts and cooperates with the telescopic mechanism; the functional core member is detachably placed on the bearing part, and the functional core member is extended or retracted into the accommodating member through the telescopic mechanism for use or storage, and the functional core member is replaced by the pull-out and replacement mechanism.

[0016] The above-mentioned carrying portion is located in the accommodating component, and the functional core member on the carrying portion is extended or retracted in the accommodating component through a telescopic mechanism, so that the functional core member can be used or stored.

[0017] In a preferred embodiment, the connector includes a locking member and a clutch bracket, the locking member being sleeved on the top of the clutch member; a socket is provided within the clutch member, a first slot is provided at the upper end of the clutch bracket, and an insert is provided at the lower end of the locking member, with a first latching block provided on the insert. The insert passes through the socket, and the first latching block engages with the first slot. The insertion and latching between the locking member and the clutch bracket prevents the clutch member from being separated from the connector.

[0018] In a further preferred embodiment, the clutch portion is located above the accommodating member and is recessed into the outer surface of the accommodating member; the clutch portion is provided with a strip guide groove; the clutch member is sleeved on the clutch portion and engages with the outer surface of the accommodating member; the strip guide groove is located within the clutch member, and the sidewall of the clutch member is shielded from the outer side of the strip guide groove; the clutch bracket is provided with a slider corresponding to the strip guide groove, which slides and limits its position within the strip guide groove. This arrangement enables relative movement between the connector and the accommodating member, and prevents the accommodating member from separating from the connector. Since the clutch member also does not separate from the connector, the clutch member, the connector, and the accommodating member form a movable but non-detachable pull-out assembly after assembly.

[0019] In a further preferred embodiment, a first guide groove is provided on the inner wall of the clutch member, and the clutch portion is provided with a first guide bar corresponding to the first guide groove. The first guide bar is sleeved in the first guide groove and can slide along the first guide groove. The clutch member can slide in a directional and stable manner on the upper portion of the accommodating member through the cooperation of the first guide bar and the first guide groove.

[0020] In a further preferred embodiment, the bearing portion is formed on the clutch bracket, and the functional core component is arranged on the clutch bracket; the lower end of the accommodating component is provided with a tape outlet, and the lower end of the functional core component has a pasting head, which can extend or retract from the tape outlet.

[0021] In a further preferred embodiment, the clutch bracket is provided with two guide plates at its lower portion. A first connecting piece is connected between the front ends of the lower ends of the two guide plates, and a second connecting piece is connected between the rear ends of the two guide plates. The two guide plates, the first connecting piece, and the second connecting piece together constitute the bearing portion. The two guide plates are connected and supported by the first and second connecting pieces provided at the front and rear ends of their lower ends, thereby ensuring a stable and deformable structure of the clutch bracket.

[0022] In a further preferred embodiment, the inner walls of both sides of the container are each provided with a first guide rail and a second guide rail, and the guide plate is movably arranged between the first guide rail and the second guide rail. The two guide plates are inserted between the first guide rail and the second guide rail so that the bearing part can slide in a directional and stable manner in the container.

[0023] In a further preferred embodiment, a second slot is provided at the lower end of the inner wall of the guide plate, a second block is provided at the lower portion of the functional core member to engage with the corresponding second slot, a stopper is provided at the upper portion of the clutch bracket, and a stopper step is provided at the upper portion of the functional core member to correspond to the stopper, and the second slot and stopper together constitute the placement position. Except for the removal direction, the functional core member placed in the placement position is restricted in all directions, ensuring that the functional core member and the clutch bracket cannot move.

[0024] In a further preferred embodiment, the functional core is provided with two outer sides of the central portion thereof, each of which engages with the first guide rail. When the functional core needs to be replaced, the limit blocks are not restricted in the removal direction, thereby allowing the functional core to be removed and replaced. When the clutch member and the receiving member are temporarily fixed, the limit blocks are restricted by the first guide rail, and the functional core is restricted in all directions, allowing the functional core and the supporting portion to move synchronously in the extension and retraction direction.

[0025] In a preferred embodiment, the clutch member is provided with a strip spring sheet at its lower portion, the strip spring sheet is provided with a hook, and the locking portion is provided with a button hole, the hook engaging with the button hole. The clutch member and the accommodating member are temporarily fixed by the hook at the lower portion of the clutch member engaging with the button hole of the accommodating member locking portion.

[0026] In a preferred embodiment, the telescopic mechanism is pressed between the clutch and the connecting member. The clutch and the connecting member limit the telescopic mechanism. When the clutch and the connecting member are able to move, the clutch, the telescopic mechanism and the connecting member are synchronously linked.

[0027] During assembly, first install the locking piece and the telescopic mechanism on the top of the clutch part, and install the clutch bracket on the accommodating part. Then, the clutch part and the accommodating part are connected by means of hooks and buckle holes to form a structural component. Finally, the functional core part is placed and temporarily fixed to complete the installation. The entire assembly process is very simple and efficient.

[0028] When replacing, you can press the strip spring to release the temporary fixation and pull the clutch part, so that the telescopic mechanism, connecting part, and functional core part are linked and limited to separate from the accommodating part. The clutch part and the accommodating part are pulled apart to form a replacement opening, and the functional core part can be disassembled and replaced.

[0029] Compared with the prior art, the present invention has the following advantages:

[0030] In the pull-out and replacement mechanism of the present invention and the stationery containing the same, the clutch part and the accommodating part are movably limited by a connecting part, the clutch part and the accommodating part are indirectly connected, the snap fit between the two is reduced, the mold structure can be greatly simplified, and the product quality is more stable and controllable; the clutch part is sunken in the outer surface of the accommodating part, so that the holes that affect the appearance, such as the strip guide groove, can be covered, and the product appearance is more refined and beautiful.

[0031] The pull-out and replacement mechanism of the present invention and the stationery containing the pull-out and replacement mechanism, the telescopic mechanism and the pull-out and replacement mechanism are integrated into a functionally complete and independent structural component, and the functional core does not contain parts such as elastic metal parts that constitute the structural component, so that the functional operation of the structural component is not restricted by the functional core, and the structure of the functional core is also simpler and lighter; the structural component can be replaced conveniently and quickly, and can be reused by replacing a relatively cheap and lightweight functional core, saving resources and costs to a certain extent.

[0040] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0041] like Figure 1-8 As shown, the pull-out and replacement mechanism in this embodiment includes:

[0042] The accommodating member 1 has an accommodating portion 11, a clutch portion 12 and a locking portion 13; the accommodating portion 11 has an accommodating space 111 for accommodating the functional core member 5;

[0043] The carrying portion 2 is located in the receiving component 1 and is used to accommodate and carry the functional core component 5;

[0044] The clutch member 3 has a snap-fit portion 31, and the clutch member 3 and the accommodating member 1 are engaged or disengaged through the clutch portion, and the clutch member 3 and the accommodating member 1 can be temporarily engaged and fixed through the snap-fit portion 31 and the locking portion 13;

[0045] The connecting member 4 is arranged between the clutch member 3 and the accommodating member 1. The clutch member 3, the connecting member 4, and the accommodating member 1 together constitute a pull-out assembly. The connecting member 4 and the accommodating member 1 can move relative to each other and can limit the range of movement. The clutch member 3 and the clutch part 12 can move relative to each other and are restricted by the connecting member 4. A replaceable opening 6 is formed between the connecting member 4, the clutch member 3 and the accommodating member 1, the size of which can be adjusted by pulling.

[0046] After the above-mentioned components are assembled, the above-mentioned connecting member 4 is movable between the clutch member 3 and the accommodating member 1, and the clutch member 3 and the connecting member 4, as well as the connecting member 4 and the accommodating member 1 are not removable, so that the clutch member 3 and the accommodating member 1 are connected through the connecting member 4 to form a pull-out assembly that is movable and non-detachable after the assembly is completed, and a replaceable opening 6 is formed whose opening size can be adjusted by pulling.

[0047] The clutch 3 and the clutch portion 12 of the receiving component 1 are capable of relative movement and are restricted by the connecting component 4. The connecting component 4 can be pulled and pulled relative to the receiving component 1, so that the size of the replacement opening 6 is changeable; when the functional core component 5 is to be replaced, the temporary fixation between the clutch 3 and the receiving component 1 is released, the replacement opening 6 becomes larger, and the functional core component 5 will not be restricted by the edge of the replacement opening 6, so that the functional core component 5 can be easily installed in the bearing portion 2 or removed from the replacement opening 6 through the replacement opening 6; when the clutch 3 and the receiving component 1 are temporarily fixed, the replacement opening 6 becomes smaller, and the functional core component 5 is restricted by the edge of the replacement opening 6, so that the functional core component 5 cannot be removed from the replacement opening 6, so that the functional core component 5 can be firmly installed in the bearing portion 2 of the receiving component 1.

[0048] The carrying portion 2 is provided with a placement location 21, and the functional core member 5 is detachably mounted in the placement location 21; the carrying portion 2 is disposed on the connecting member 4 or the clutch member 3. Since the carrying portion 2 is disposed on the connecting member 4 or the clutch member 3, and the functional core member 5 is disposed on the carrying portion 2, when the connecting member 4 or the clutch member 3 is withdrawn, the functional core member 5 can be withdrawn and pulled into the accommodating member 1 along with the connecting member 4 or the clutch member 3.

[0049] Typically, the functional core 5 generally refers to a replaceable component with a specific function and a complete and independent structure, such as a replacement pen core, a replacement tape core, a correction tape core, an adhesive tape core, etc. When the functional core 5 needs to be replaced, the temporary fixation between the engaging portion 31 of the clutch 3 and the locking portion 13 of the accommodating portion 1 can be released first, and the clutch 3 can be pulled out of the accommodating portion 1, and then a new functional core 5 can be replaced through the replacement opening 6 for use. This pull-out replacement mechanism is very convenient and quick to replace, and the functional components are connected as one, so that the pull-out replacement mechanism can be reused by replacing the relatively cheap and lightweight functional core 5, which saves resources and costs to a certain extent, and can be applied to frequently consumed stationery products such as transfer utensils or writing utensils.

[0050] This embodiment also provides a stationery item containing the above-mentioned pull-out and replacement mechanism, including a functional core 5, a telescopic mechanism 7 and the above-mentioned pull-out and replacement mechanism; the telescopic mechanism 7 is movably arranged in the clutch 3, and the connecting part 4 is in abutment with the telescopic mechanism 7; the functional core 5 is detachably placed on the bearing part 2, and the functional core 5 is extended or retracted into the accommodating part 1 through the telescopic mechanism 7 for use or storage, and the functional core 5 is replaced by the pull-out and replacement mechanism.

[0051] The carrying portion 2 is located in the accommodating component 1 , and the functional core 5 on the carrying portion 2 is extended or retracted in the accommodating component 1 through the telescopic mechanism 7 , so that the functional core 5 can be used or stored.

[0052] Connector 4 includes a locking member 41 and a clutch bracket 42. Locking member 41 is sleeved on the top of clutch member 3. Clutch member 3 is provided with an insertion hole 32. The upper end of clutch bracket 42 is provided with a first engaging slot 421. The lower end of locking member 41 is provided with an insert 411, which is provided with a first engaging block 412.

The clutch portion 12 is provided with a strip guide groove 121. The clutch member 3 is sleeved on the clutch portion 12 and engages with the outer surface of the accommodating member 1. The strip guide groove 121 is located within the clutch member 3, and the sidewall of the clutch member 3 is shielded from the outer side of the strip guide groove 121. The clutch bracket 42 is provided with a slider 422 corresponding to the strip guide groove 121. The slider 422 slides and limits its position within the strip guide groove 121. This arrangement enables relative movement between the connector 4 and the accommodating member 1, and prevents the accommodating member 1 from separating from the connector 4. Since the clutch member 3 is also not separated from the connector 4, the clutch member 3, the connector 4, and the accommodating member 1 form a movable and non-detachable pull-out assembly after assembly.

[0054] A first guide groove 33 is defined on the inner wall of the clutch member 3, and the clutch portion 12 is provided with a first guide bar 122 corresponding to the first guide groove 33. The first guide bar 122 is sleeved within the first guide groove 33 and is capable of sliding along the first guide groove 33. The clutch member 3 can slide in a directional and stable manner on the upper portion of the accommodating member 1 through the cooperation between the first guide bar 122 and the first guide groove 33.

[0055] The bearing portion 2 is formed on the clutch bracket 42, and the functional core component 5 is arranged on the clutch bracket 42; the lower end of the accommodating component 1 is provided with a tape outlet 14, and the lower end of the functional core component 5 has a pasting head 51, which can extend or retract from the tape outlet 14.

[0056] The clutch bracket 42 is provided with two guide plates 423 at its lower portion. A first connecting piece 424 is connected between the front ends of the lower ends of the two guide plates 423, and a second connecting piece 425 is connected between the rear ends of the two guide plates 423. The two guide plates 423, the first connecting piece 424, and the second connecting piece 425 together constitute the support portion 2. The two guide plates 423 are connected and supported by the first connecting piece 424 and the second connecting piece 425 at the front and rear ends of their lower ends, ensuring the structural stability of the clutch bracket 42.

[0057] The inner walls of both sides of the container 1 are respectively provided with a first guide rail 15 and a second guide rail 16, and the guide plate 423 is movably arranged between the first guide rail 15 and the second guide rail 16. The two guide plates 423 are inserted between the first guide rail 15 and the second guide rail 16, so that the bearing part 2 can slide in the container 1 in a directional and stable manner.

[0058] A second slot 426 is defined at the lower end of the inner wall of the guide plate 423. A second latch block 52 is positioned below the functional core 5, engaging with the corresponding second slot 426. A stopper 427 is positioned above the clutch bracket 42, and a stopper step 53 corresponding to the stopper 427 is positioned above the functional core 5. Together, the second slot 426 and stopper 427 form the resting position 21. The functional core 5 positioned in the resting position 21 is restrained in all directions except the removal direction, ensuring that the functional core 5 and the clutch bracket 42 cannot move.

[0059] Limit blocks 54 are provided on the two outer sides of the central portion of the functional core 5, respectively, and engage with the first guide rail 15. When the functional core 5 needs to be replaced, the limit blocks 54 are not restricted in the removal direction, allowing the functional core 5 to be removed and replaced.

[0060] The clutch member 3 is provided with a strip-shaped spring piece 34 at its lower portion, which is provided with a hook 35. The locking portion 13 is provided with a buckle hole 131, and the hook 35 engages with the buckle hole 131. By engaging the hook 35 at the lower portion of the clutch member 3 with the buckle hole 131 of the locking portion 13 of the accommodating member 1, the clutch member 3 and the accommodating member 1 are temporarily fixed.

[0061] The telescopic mechanism 7 is pressed between the clutch 3 and the connecting member 4. The above-mentioned telescopic mechanism 7 is pressed between the clutch 3 and the connecting member 4. The clutch 3 and the connecting member 4 limit the telescopic mechanism 7. When the clutch 3 and the connecting member 4 are able to move, the clutch 3, the telescopic mechanism 7, and the connecting member 4 are synchronously linked.

[0062] During assembly, first install the locking piece 41 and the telescopic mechanism 7 on the top of the clutch 3, and install the clutch bracket 42 on the accommodating part 1. Then, the clutch 3 and the accommodating part 1 are connected by the hook 35 and the buckle hole 131 to form a structural component. Finally, the functional core 5 is placed and temporarily fixed to complete the installation. The entire assembly process is very simple and efficient.

[0063] When replacing, the strip spring piece 34 can be pressed to release the temporary fixation and the clutch part 3 can be pulled out, so that the telescopic mechanism 7, the connecting part 4, and the functional core part 5 are linked and limited to separate from the accommodating part 1.
