Description

Technical Field

[0001] This utility model belongs to the field of folding handcart technology, and in particular relates to a new type of telescopic mop and folding handcart. Background Technology

[0002] Folding trolleys are convenient tools for short-distance transport of items or luggage. With their good load-bearing capacity and small space-saving design when folded, they are increasingly being used by people for daily transport and outdoor activities.

[0003] Currently, folding strollers on the market offer a variety of functions. For example, utility model patent application number 2024201153361 mentions a safety stroller with anti-tipping features. This stroller mainly includes a folding frame and an anti-tipping handle assembly (telescopic mop). The anti-tipping handle assembly includes a first link, a second link, and a handle. The first link is mounted on the folding frame, and the second link is telescopically and rotatably mounted inside the first link and fixed to the handle. A limiting component is also installed on the second link. During use, the handle is gripped to pull out the second link, which is then stopped by the limiting component against the first link. In the event of a tipping over, the handle and the second link rotate circumferentially relative to the first link, preventing injury to the user's wrists and hands from the tipping over and improving safety. However, during use, the following problems have been found: Firstly, the second link can only rotate normally relative to the first link and thus have the anti-rollover function when it is fully extended. During the extension or retraction of the second link, or after it is fully retracted, the second link is difficult to rotate and lose the anti-rollover function, so there is still a certain degree of danger.

[0004] Secondly, when retracting the second link, the user needs to press the limiting part from the side of the second link, which is more troublesome. Also, when the second link rotates with the first link, it is easy to wear the second link and the limiting part, resulting in a reduced service life. Utility Model Content

Detailed Implementation

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this application. It is understood that the accompanying drawings are provided for reference and illustration only, and are not intended to limit this application. The connection relationships shown in the accompanying drawings are only for clear description and do not limit the connection method.

[0020] See appendix Figure 1 - Appendix Figure 2 and attached Figure 5 - Appendix Figure 14A novel telescopic mop includes a telescopic rod 1 and a locking mechanism 2. The telescopic rod 1 includes an outer rod 11, an inner rod 12, and a handle 13. The outer rod 11 has a first locking hole 111 on its side wall. The inner rod 12 is slidably installed inside the outer rod 11. The handle 13 is rotatably installed at the top of the inner rod 12 and has a button 131. The locking mechanism 2 includes a lock 21 and a drive bar 22. The lock 21 is installed at the bottom of the inner rod 12 and has a locking block 210. The lock 21 is capable of driving the locking block 210 to insert. The first card hole 111 is in its initial state, and the card block 210 is in a pressed state, which causes the first card hole 111 to disengage from the first card hole 111. One end of the drive bar 22 abuts against the button 131, and the other end of the drive bar 22 extends slidably into the inner rod 12 and connects to the lock 21. Pressing the button 131 can drive the drive bar 22 to move down and apply pressure to the lock 21 so that the lock 21 is in a pressed state. Releasing the button 131 will switch the lock 21 back to its initial state, thereby driving the drive bar 22 and the button 131 to move up and reset.

[0021] Specifically, before use, the locking block 210 disengages from the first locking hole 111 and the inner rod 12 is fully retracted inside the outer rod 11, while the handle 13 can rotate normally relative to the inner rod 12. During use, hold the handle 13 and pull the inner rod 12 out from inside the outer rod 11 until the locking block 210 aligns with and engages with the first locking hole 111, thus putting the lock 21 in its initial state. At this time, the handle 13 can also rotate normally relative to the inner rod 12. After use, press the button 131 to move the drive bar 22 down and apply pressure to the lock 21, so that the lock 21 switches to the pressed state where the locking block 210 disengages from the first locking hole 111. At this time, the restriction on the inner rod 12 is released, allowing the inner rod 12 to retract along the outer rod 11. During the retraction process, the handle 13 can still rotate normally relative to the inner rod 12. After the inner rod 12 is fully retracted inside the outer rod 11, release the button 131.

[0022] In summary, this telescopic mop simplifies operation and improves ease of use by using a button 131 on the handle 13 to control the switching of the locking mechanism 21's usage state. Since the inner rod 12 cannot rotate during use, wear on the inner rod 12 and locking mechanism 21 is reduced, extending the lifespan of related components. Furthermore, because the handle 13 remains rotatably connected to the inner rod 12 throughout use, it provides an anti-tipping function, significantly reducing the possibility of wrist injuries and effectively improving safety.

[0023] It should be noted that the outer rod 11 of this telescopic mop can be connected to regular strollers, baby carriages, folding strollers and other vehicles. Due to the variety of vehicles, this utility model does not impose any restrictions on this.

[0024] See appendix Figure 6 - Appendix Figure 10The locking component 21 includes a slide block 211, a linkage block 212, and a first spring 213. The slide block 211 is installed at the bottom end of the inner rod 12. The linkage block 212 is slidably installed on the slide block 211 and fixed to the drive bar 22. The linkage block 212 is provided with an inclined groove 212h. The locking block 210 is slidably installed on the slide block 211 and is provided with a sliding post 210h that slides with the groove 212h. The first spring 213 is installed inside the slide block 211, and the two ends of the first spring 213 abut against the inner wall of the slide block 211 and the locking block 210, respectively.

[0025] Specifically, when the button 131 is pressed, the drive bar 22 moves downward to apply pressure to the linkage block 212. The sliding column 210h of the locking block 210 moves upward along the sliding groove 212h of the linkage block 212, causing the locking block 210 to disengage from the first locking hole 111 and compress the first spring 213. At this time, the user can slide the inner rod 12 normally for extension and retraction. When the inner rod 12 is fully extended, the button 131 is released, and the first spring 213 releases its energy to drive the locking block 210 to move towards the first locking hole 111. During this process, the sliding column 210h of the locking block 210 moves downward along the sliding groove 212h of the linkage block 212, causing the linkage block 212 to move upward. The upward-moving linkage block 212 will drive the button 131 to move upward and reset through the drive bar 22 for easy operation next time.

[0026] It should be noted that the slide block 211 can be fixed to the bottom end of the inner and outer rods 11 by snap-fit, glue bonding, or even directly by screw installation. The above installation methods can facilitate the disassembly and replacement of related components, improve maintenance convenience, and since there are various related installation methods, this utility model does not limit this. On the other hand, in addition to the above structure, the locking component 21 can also adopt other structures to achieve the corresponding functions. For example, a screw motor, cylinder or other driving component can be installed at the bottom end of the inner rod 12 to push the locking block 210, and the button 131 can be set as a control button 131 for controlling the start and stop of the driving component. Since there are various related structures of the locking component 21, this utility model does not limit this either.

[0027] As attached Figure 15 As shown, in another embodiment, the outer rod 11 may be provided with symmetrical first locking holes 111 on both sides of the outer rod 11, the linkage block 212 is provided with two symmetrical sliding grooves 212h, the locking block 210 is provided with two and symmetrically arranged on the slide block 211, and the sliding post 210h of the two locking blocks 210 slides in cooperation with the two sliding grooves 212h respectively, and the two ends of the first spring 213 abut against the two locking blocks 210 respectively.

[0028] Specifically, when button 131 is pressed, causing drive bar 22 to move linkage block 212 downward, the sliding pins 210h of the two locking blocks 210 slide upward synchronously along the two sliding grooves 212h, so as to drive the two locking blocks 210 to move closer to each other and squeeze the first spring 213; when button 131 is released, the first spring 213 is released and restored, and drives the two locking blocks 210 to move away from each other, so that the sliding pins 210h of the two locking blocks 210 slide upward synchronously along the two sliding grooves 212h, thereby driving linkage block 212 and drive bar 22 to move upward and reset button 131.

[0029] Therefore, the combined use of the two locking blocks 210 and the two first locking holes 111 can increase the connection stability between the bottom end of the inner rod 12 and the top end of the outer rod 11, thereby reducing the shaking of the inner rod 12 during use and further improving the user experience; while the combined use of the two sliding columns 210h and the two sliding grooves 212h can enable smooth transmission between the locking blocks 210 and the linkage block 212, thereby increasing the operational stability of the lock 21.

[0030] See appendix Figure 5 - Appendix Figure 7 A limiting block 110 is installed at the top of the outer rod 11. When the inner rod 12 slides inside the outer rod 11 and the slide block 211 abuts against the limiting block 110, the locking block 210 aligns with the first locking hole 111.

[0031] Specifically, the design of the limiting block 110 can prevent the bottom end of the inner rod 12 from disengaging from the outer rod 11, while the auxiliary locking block 210 aligns with the first locking hole 111, further improving the ease of operation.

[0032] It should be noted that the limiting block 110 can be fixed to the top of the outer rod 11 by snap-fit, glue bonding, or even by direct screw installation. The above installation methods can facilitate the disassembly and replacement of related components, improve maintenance convenience, and since there are various related installation methods, this utility model does not limit them.

[0033] See appendix Figure 5 - Appendix Figure 7 The outer rod 11 has multiple first locking holes 111 arranged in the length direction, and the bottom of the outer rod 11 is also provided with a second locking hole 112. When the inner rod 12 is completely retracted into the outer rod 11, the locking block 210 is inserted into the second locking hole 112.

[0034] Specifically, before use, the inner rod 12 is fully retracted inside the outer rod 11, and the locking block 210 is inserted into the second locking hole 112, so that the lock 21 is in its initial state, and the handle 13 can rotate normally relative to the inner rod 12. When using, first hold the handle 13 and press the button 131 to switch the lock 21 to the pressed state, so that the locking block 210 disengages from the second locking hole 112. Then pull the inner rod 12 out from the outer rod 11 until the locking block 210 is aligned with the first locking hole 111. Then release the button 131 to allow the locking block 210 to be inserted into the first locking hole 111, so that the lock 21 is switched to the initial state. At this time, the handle 13 can also rotate normally relative to the inner rod 12. Since there are multiple first locking holes 111, during the sliding of the inner rod 12, the locking block 210 can be aligned and engaged with different first locking holes 111 to fix the inner rod 12 in the current position, and then the appropriate telescopic length can be adjusted for use.

[0035] Therefore, the design of the second locking hole 112 can not only make the inner rod 12 more stably locked with the outer rod 11 when it is fully retracted, but also ensure that the locking member 21 is in the initial state when the inner rod 12 is fully retracted, so as to reduce the burden on the locking member 21; while the design of multiple first locking holes 111 makes it convenient for users to adjust the telescopic length according to their needs, and ensures that the anti-tipping function is available at any telescopic length, further improving the user experience.

[0036] See appendix Figure 5 - Appendix Figure 8 The top of the inner rod 12 is equipped with a first fastening block 120 with a rotating shaft 1200. The handle 13 is rotatably connected to the rotating shaft 1200. The handle 13 is also equipped with a second spring 132 with a drive bar 22 sleeved inside. The two ends of the second spring 132 abut against the button 131 and the rotating shaft 1200 respectively.

[0037] Specifically, when button 131 is pressed, the drive bar 22 causes the linkage block 212 to move downward, compressing the second spring 132. When button 131 is released, the second spring 132 releases its energy and returns to its original position, thus resetting button 131. Therefore, the design of the second spring 132 ensures that button 131 is easier to reset and also improves the operating feel. On the other hand, during use, since the handle 13 is rotatably connected to the pivot 1200 and the drive bar 22 cannot interfere with the rotation of button 131, the inner rod 12 does not affect the normal rotation of the telescopic handle 13. Furthermore, the pivot 1200 can provide a force point for the second spring 132 and facilitate the independent installation of the handle 13.

[0038] It should be noted that the first fastening block 120 can be fixed to the top of the inner rod 12 by snap-fit, glue bonding, or even by direct screw installation. The above installation methods can facilitate the disassembly and replacement of related components, improve maintenance convenience, and since there are various related installation methods, this utility model does not limit them.

[0039] See appendix Figure 6 - Appendix Figure 8 The button 131 has a first groove 1311 inside, the rotating shaft 1200 has a second groove 1201 inside, and the two ends of the second spring 132 abut against the inner wall of the first groove 1311 and the inner wall of the second groove 1201 respectively; the inner wall of the first groove 1311 also has a notch 1312, and the end of the drive bar 22 is placed in the notch 1312 and abuts against the inner wall of the notch 1312.

[0040] Specifically, the first groove 1311 and the second groove 1201 can provide installation space for both ends of the second spring 132, respectively, to prevent the second spring 132 from deviating during use; while the notch 1312 can provide placement space for the end of the drive bar 22, to prevent the drive bar 22 from deviating from the button 131 during use; therefore, the above structures are all designed to further improve the structural stability of the relevant components and effectively reduce the damage rate.

[0041] See appendix Figure 5 Appendix Figure 11 - Appendix Figure 14 The telescopic rod 1 also includes a fixed base 14, a connecting block 15, a lever 16, a pressure block 17, and a third spring 18; the fixed base 14 is mounted on the outer rod 11 and has a fixed cavity 140 with a movable groove 141; the connecting block 15 is mounted in the fixed cavity 140 and has a vertically arranged through hole 151 and a horizontally arranged movable groove 152, and the through hole 151 connects the movable groove 141 and the movable groove 152; the lever 16 is movably mounted inside the front side of the movable groove 152, and the lever 16 has a connecting post 161 that penetrates the inner wall of the movable groove 152; the third spring 18 is sleeved on the connecting post 161, and the third The two ends of the spring 18 abut against the inner wall of the moving groove 152 and the lever 16 respectively; the pressure block 17 is movably installed inside the back side of the moving groove 152 and fixed to the connecting column 161, and the pressure block 17 is also provided with a buckle 171; the outer rod 11 can pass through the movable groove 141 and the moving groove 152 to the outside in sequence, and the bottom end of the outer rod 11 is equipped with a second fastening block 113 with a locking position 1130; when the third spring 18 is in the initial state, the buckle 171 engages with the locking position 1130 to lock the outer rod 11, and when the lever 16 is pressed to disengage the buckle 171 from the locking position 1130 and release the outer rod 11, the third spring 18 deforms and stores energy.

[0042] Specifically, when the telescopic mop is not in use, the inner rod 12 is fully retracted into the outer rod 11, causing the limiting block 110 to abut against the fixed seat 14. Meanwhile, the bottom end of the outer rod 11 moves away from the fixed seat 14, causing the buckle 171 to disengage from the locking position 1130 and compress the third spring 18, thereby ensuring that the telescopic rod 1 is in a fully retracted state. When the telescopic mop needs to be used, first move the outer rod 11 along the movable groove 141. After the buckle 171 aligns with the locking position 1130, the third spring 18 releases its energy and moves the lever 16 away from the outer rod 11. The lever 16 then moves the pressure block 17 closer to the outer rod 11 through the connecting column 161 until the buckle 171 engages with the locking position 1130 to restrict the movement of the outer rod 11. At this point, press the button 131 and pull the handle 13 to unfold the inner rod 12, allowing the telescopic rod 1 of the telescopic mop to be fully unfolded for use.

[0043] After use, press and push the handle 13 to retract the inner rod 12, then press the lever 16 to bring it closer to the outer rod 11. The lever 16, through the connecting column 161, drives the pressure block 17 away from the outer rod 11, causing the buckle 171 to disengage from the locking position 1130. Then continue to push the handle 13 to move the outer rod 11 along the movable groove 141 until the bottom of the outer rod 11 moves away from the fixed seat 14 and the limiting block 110 abuts against the fixed seat 14 again, so that the telescopic rod 1 of this telescopic mop can be fully retracted again.

[0044] Therefore, the coordinated use of the fixed base 14, connecting block 15, lever block 16, pressure block 17 and third spring 18 ensures that the telescopic rod 1 of this telescopic mop has a two-stage telescopic function. In this case, when this telescopic mop is installed on a regular stroller, baby stroller, folding stroller and other vehicles via the fixed base 14, it has a larger telescopic range and can be extended to a larger extent or retracted to a smaller extent, further meeting the user's needs and improving portability.

[0045] It should be noted that the fixing seat 14 can be fixed to the bottom end of the outer rod 11 by snap-fit, glue bonding, or even directly by screw installation; the connecting block 15 can be installed in the fixing cavity 140 of the fixing seat 14 by snap-fit, glue bonding, or even directly by screw installation; and the second fastening block 113 can be fixed to the bottom end of the outer rod 11 by snap-fit, glue bonding, or even directly by screw installation. The above installation methods can facilitate the disassembly and replacement of the telescopic rod 1, improve the convenience of maintenance, and since there are various related installation methods, this utility model does not limit them.

[0046] See appendix Figure 1 - Appendix Figure 7A folding trolley includes a folding frame 3 and a telescopic mop. When the telescopic mop does not include a fixed seat 14, an outer rod 11 is connected to the folding frame 3 so that the telescopic mop is mounted on the folding frame 3. When the telescopic mop includes a fixed seat 14, the fixed seat 14 is connected to the folding frame 3 so that the telescopic mop is mounted on the folding frame 3.

[0047] Specifically, under normal circumstances, the folding frame 3 is in a folded state, while the telescopic rod 1 of the telescopic mop is fully retracted to minimize the overall size and ensure portability. When in use, the folding frame 3 is expanded and the telescopic rod 1 of the telescopic mop is unfolded, allowing the user to pull or push the folding frame 3 by holding the handle 13. Since this folding stroller uses this telescopic mop, it also has advantages such as full anti-tipping, easy operation, and long service life. For related information, please refer to the above text, which will not be repeated here.

[0048] See appendix Figure 1 - Appendix Figure 7 The folding frame 3 includes a center seat 31, support columns 32, and side frames 33. At least four support columns 32 are provided and distributed at the four corners of the center seat 31, and casters 34 are installed at the bottom of each support column 32. Four base rods 311 are hinged to the center seat 31, and each of the four base rods 311 is hinged to one of the four support columns 32. The side frames 33 are located between two adjacent support columns 32, and each side frame 33 includes at least one set of X-shaped folding frames 331. The upper end of one side of the X-shaped folding frame 331 connecting to the support column 32 is hinged to the corresponding support column 32, and its lower end is slidably hinged to the corresponding support column 32. Two swing rods 142 are hinged to both sides of the fixed base 14, and the two swing rods 142 are respectively hinged to two adjacent support columns 32. A coil spring 143 is installed at the hinge point between the swing rod 142 and the support column 32.

[0049] Specifically, when in use, pulling the four support columns 32 will simultaneously drive the side frames 33 and the four base rods 311, thereby folding or expanding the folding frame 3.

[0050] During the expansion of the folding frame 3, multiple casters 34 contact the ground and remain sliding to provide support for the folding frame 3. The swing arms 142 on both sides of the fixed base 14 also swing accordingly. After the folding frame 3 is fully expanded, the swing arms 142 on both sides of the fixed base 14 swing to their maximum amplitude. At this time, the user first swings the telescopic mop to deform the coil spring 143, and then fully unfolds the telescopic rod 1 of the telescopic mop. The user can then hold the handle 13 to pull or push the folding frame 3. During the folding of the folding frame 3, multiple casters 34 contact the ground and remain sliding to provide support for the folding frame 3. The swing arms 142 on both sides of the fixed base 14 also swing accordingly. After the folding frame 3 is fully folded, the swing arms 142 on both sides of the fixed base 14 swing to their minimum amplitude. At this time, the user first fully retracts the telescopic rod 1, and then releases the handle 13. The coil spring 143 releases energy to restore the telescopic mop, making the overall volume as small as possible for carrying.

[0051] Therefore, the above-mentioned structural design not only facilitates the use of the folding frame 3 and the telescopic mop, but also has strong structural stability. In addition to the above-mentioned structure, the folding frame 3 can also adopt other structures. Since there are many types of related structures and they are relatively common in the field, this utility model does not impose any restrictions on them.

[0052] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
