[0082] Reference Figures 1 to 5 According to a first aspect of the present invention, the handle structure includes: a handle body 1, a telescopic mechanism, and a flipping mechanism.

[0083] The handle body 1 includes an operating part 11 and an execution part 12. The execution part 12 is disposed on one or both sides of the operating part 11 and is disposed at the mounting position 2 of the handle structure. The handle structure is rotatably mounted at the mounting position 2. The operating part 11 is provided with a rotatable sleeve 311 and a fixed sleeve 3112 for rotating the sleeve 311. The sleeve 311 is fitted with a pipe fitting 13, and the fixed sleeve 3112 is fitted onto the pipe fitting 13 and abuts against both ends of the sleeve 311. The pipe fitting 13 is provided with a plurality of snap-fit ​​holes 1331, and the mounting position 2 is provided with a first snap-fit ​​groove 2a. A telescopic mechanism is disposed on the handle body 1. The telescopic mechanism includes a first operating component 21 and a first moving part 22. The first operating component 21 is connected to the first action component 22. The first operating component 21 is disposed on the sleeve 311. The first action component 22 is disposed in the execution part 12. The telescopic mechanism is used to control the telescopic extension and retraction of the handle body 1. The flipping mechanism is disposed on the handle body 1. The flipping mechanism includes a second operating component 31 and a second action component 32. The second operating component 31 is connected to the second action component 32. The second operating component 31 is disposed in the sleeve 311 and located on one side of the first operating component 21. The inner side of the sleeve 311 is engaged with the second operating component 31. The second action component 32 is disposed in the execution part 12. The flipping mechanism is used to flip the handle body 1.

[0084] The first actuation component 22 includes a slidable first locking tongue 221, which can be engaged in the engagement hole 1331. The first operation component 21 is connected to the first locking tongue 221 and drives the first locking tongue 221 to engage in the engagement hole 1331. The second actuation component 32 includes a movable engagement block 3231, which can be engaged in the first engagement groove 2a. The second operation component 31 is connected to the engagement block 3231. Rotating the sleeve 311 drives the second operation component 31 to drive the engagement block 3231 to separate from the first engagement groove 2a.

[0085] In some embodiments, execution units 12 can be provided on both sides of the operation unit 11. A first operation component 21 and a second operation component 31 are provided on both sides of the operation unit 11 to control the first action component 22 and the second action component 32. Therefore, the movement of the execution units 12 on both sides of the operation unit 11 can be controlled, thereby achieving simultaneous extension, retraction, or folding of the execution units 12. Similarly, in other embodiments, the execution unit 12 can be provided on one side of the operation unit 11. In this case, the key component is also located on the side corresponding to the execution unit 12. For example, in some single-pole trolleys, the extension, retraction, and / or folding can be achieved by controlling the execution unit 12 in the tube 13 of the single-pole trolley.

[0086] Specifically, the operating part 11 is provided with a rotating sleeve 311 and a fixed cylinder 3112 for rotating the sleeve 311. Both ends of the sleeve 311 are rotatably mounted on the fixed cylinder 3112. Therefore, the first operating component 21 and the second operating component 31 mounted on the sleeve 311 can control the first action component 22 and the second action component 32 by operating the sleeve 311 or by directly operating themselves. It should be noted that in some embodiments, both ends of the sleeve 311 can be directly mounted on the pipe fitting 13, that is, the sleeve 311 is rotatably fitted onto the pipe fitting 13. By driving the rotation of the sleeve 311 or the components of the first operating component 21 and the second operating component 31, the first action component 22 and the second action component 32 are driven to perform extension and retraction and folding actions, respectively.

[0087] More specifically, during the extension and retraction of the handle body 1, the first operating component 21 on the operating part 11 drives the first locking tongue 221 on the first actuation component 22. The first operating component 21, in conjunction with the sleeve 311, drives the first locking tongue 221 to extend and retract into the locking hole 1331 on the pipe fitting 13, thus the first locking tongue 221 can be locked into the locking hole 1331 on the pipe fitting 13. When the first locking tongue 221 retracts into the pipe fitting 13, the first locking tongue 221 disengages from the locking hole 1331, and the pipe fitting 13 can then extend and retract; and when the first locking tongue 221 extends out of the pipe fitting 13, the first locking tongue 221 can be locked into the locking hole 1331 on the pipe fitting 13, thereby fixing the length of the pipe fitting 13. Therefore, it is understandable that the fitting 13 has a series of snap-fit ​​holes 1331 arranged on it. Depending on the position of the snap-fit ​​holes 1331, the handle structure has different lengths, thus giving the handle structure a telescopic function.

[0088] Similarly, during the flipping and folding or unfolding of the handle body 1, the second operating component 31 on the operating part 11 drives the locking block 3231 on the second action component 32. The second operating component 31, in conjunction with the sleeve 311, drives the first locking groove 2a that is movable in the installation position 2. Thus, the locking block 3231 can be locked in the first locking groove 2a or can be released from the locking constraint of the first locking groove 2a. Therefore, the purpose of fixing the position of the pipe 13 can be achieved by the constraint of the installation position 2, or the purpose of flipping the position of the pipe 13 can be achieved by releasing the constraint of the installation position 2. That is, the handle structure can flip its own position through the rotation connection of the actuator 12, thereby giving the handle structure the function of flipping and folding. Therefore, if it is necessary to fold the handle structure, the handle structure should be shortened by the telescopic mechanism before the handle structure can be flipped and folded by the flipping mechanism.

[0089] Therefore, in summary, the user can operate the first operating component 21 and the second operating component 31 on the sleeve 311 with one hand, and control the extension, retraction and folding of the handle structure by rotating the sleeve 311. Therefore, the handle structure proposed in this embodiment of the invention is convenient for the user to use and facilitates the user to fold the trolley.

[0090] Reference Figure 6 In some embodiments of the present invention, the pipe fitting 13 specifically includes a U-shaped pipe 131, and the first operating component 21 is disposed in the middle of the U-shaped pipe 131. It can be understood that the handle structure in this embodiment is provided with two actuators 12 and respectively disposed at both ends of the operating component 11. Therefore, the first operating component 21 controls the first action component 22 on the actuators 12 at both ends respectively.

[0091] More specifically, the first operating component 21 may include a pressing block 211 and a first traction member 212. The pressing block 211 is movably disposed in the sleeve 311, with a portion of the pressing block 211 located on the outside of the sleeve 311 for user pressing. The first traction member 212 is disposed in the channel inside the tube 13 and located on both sides of the pressing block 211. One end of the first traction member 212 is connected to one side of the pressing block 211, and the other end of the first traction member 212 is connected to the first actuation component 22. When the user presses the pressing block 211 exposed on the outside of the sleeve 311, the pressing block 211 on the inside of the sleeve 311 is driven toward the inside of the U-shaped tube 131, thereby pulling the first traction member 212 inward. Finally, the first actuation component 22, which is pulled by the other end of the first traction member 212, is activated, causing the first locking tongue 221 on the first actuation component 22 to engage in the locking hole 1331. The pulled first locking tongue 221 disengages from the snap-fit ​​hole 1331 on the tube 13, thereby allowing the tube 13 to extend and retract. It should be noted that the first traction member 212 in this embodiment can be a common flexible steel rope, or a general flexible but inelastic rope, etc., and is not limited in this invention. It should also be noted that, in order to reset the pressing block 211, an elastic member (not shown in the figure) for reset is provided between the pressing block 211 and the U-shaped tube 131. One end of this elastic member abuts against the pressing block 211, and the other end abuts against the inner U-shaped tube 131. Therefore, it can be understood that when the user releases the pressing block 211, the pressing block 211 resets under the action of the elastic member, facilitating the next pressing use.

[0092] Reference Figure 6 Furthermore, in some embodiments of the present invention, the first operating component 21 may further include a first tensioning wheel 213. The first tensioning wheel 213 is disposed on one side of the pressing block 211 and located in the sleeve 311. The first traction members 212 on both sides are respectively arranged around the periphery of the first tensioning wheel 213. The first tensioning wheel 213 is used to tension the first traction members 212. The periphery of the first tensioning wheel 213 may be provided with a recessed groove. Placing the first traction member 212 in the groove can prevent the first traction member 212 from sliding out from both ends of the first tensioning wheel 213 when sliding. Therefore, it can be understood that the first tensioning wheel 213 can tension the first traction member 212, thereby facilitating the pulling of the first operating component 22. However, it should be noted that one end of the pressing block 211 connected to the first traction member 212, that is, the inner side of the pressing block 211, should be higher than the height of the first tensioning wheel 213, so that the tensioning effect of the first tensioning wheel 213 can be better. At the same time, the different heights of the first tensioning wheel 213 and the traction end of the first traction member 212 can make the traction stroke of the first traction member 212 larger and the traction effect better.

[0093] Reference Figure 6 Furthermore, in some embodiments of the present invention, the first operating component 21 further includes a support plate 214, which is disposed in the channel inside the U-shaped tube 131. The support plate 214 has through holes at both ends for the first traction member 212 to pass through. Therefore, it can be understood that the first traction member 212 enters the channel inside the U-shaped tube 131 through the connecting holes, and simultaneously passes through the through holes at both ends of the support plate 214 from bottom to top, then passes towards the first actuating components 22 on both sides. Since the support plate 214 is located inside the U-shaped tube 131, its height is higher than the height of the first tensioning wheel 213. Therefore, the support plate 214, in conjunction with the first tensioning wheel 213, can effectively tension the first traction member 212, thereby facilitating the first traction member 212 to pull the first actuating component 22.

[0094] Reference Figure 6 In some embodiments of the present invention, the pressing block 211 mentioned above may be provided with a first mounting hole 2111 and a first mounting groove 2112 on both sides. The first mounting hole 2111 is used to install the first locking head at the end of the first traction member 212, and the first mounting groove 2112 is used to avoid the traction portion 2114 of the first traction member 212. In order to facilitate the rapid assembly of the first operating component 21, the first traction member 212 may include a first locking head and a traction portion 2114 connected to the first locking head. Therefore, by quickly installing the first locking head in the first mounting hole 2111, a rapid connection can be achieved, and the first traction member 212 can be easily disassembled. In addition, the first mounting groove 2112 on the pressing block 211 can be used to avoid the traction portion 2114 of the first traction member 212, thereby facilitating the traction of the traction portion 2114 and preventing the pressing block 211 from wearing down the traction portion 2114 of the first traction member 212.

[0095] Reference Figures 1 to 3 as well as Figure 7 In some embodiments of the present invention, the fitting 13 further includes a connecting pipe 132 and a telescopic pipe 133. One end of the connecting pipe 132 is connected to both ends of the U-shaped pipe 131, and the other end of the connecting pipe 132 can be inserted into the telescopic pipe 133. A plurality of snap-fit ​​holes 1331 are provided on one side of the telescopic pipe 133, and the first actuating component 22 is provided at the end of the connecting pipe 132. When the first actuating component 21 drives the first locking tongue 221 to retract from the snap-fit ​​holes 1331 arranged on the telescopic pipe 133, the connecting pipe 132 can extend and retract in the telescopic pipe 133, while simultaneously driving the first actuating component 22 to shuttle in the telescopic pipe 133 until the first locking tongue 221 slides to the next snap-fit ​​hole 1331, at which point it pops out and snaps into the snap-fit ​​hole 1331, thereby realizing the extension, retraction, and fixation of the handle body.

[0096] Reference Figures 7 to 10In some embodiments of the present invention, the first actuating component 22 further includes a first housing 222, a first driving block 223, and a first elastic member 224. The first housing 222 is inserted into one end of the connecting pipe 132, and a first sliding groove 2221 is provided inside the first housing 222. The first driving block 223 is slidably disposed in the first sliding groove 2221, and one end of the first driving block 223 is connected to the first operating component 21. The first operating component 21 drives the first driving block 223 to slide in the first sliding groove 2221. The first elastic member 224 is disposed in the first sliding groove 2221 and located in the first driving block 223. One end of the first elastic member 224 abuts against the inner wall of the first sliding groove 2221, and the other end of the first elastic member 224 abuts against the inner wall of the first driving block 223.

[0097] The first locking tongue 221 is slidably disposed in the first housing 222. One end of the first locking tongue 221 can extend out of the outside of the first housing 222. The other end of the first locking tongue 221 is provided with a second elastic member 225. One end of the second elastic member 225 abuts against the inner wall of the first housing 222, and the other end of the second elastic member 225 abuts against the other end of the first locking tongue 221. The other end of the first driving block 223 passes through the middle of the first locking tongue 221. The middle of the first locking tongue 221 is provided with a first driving inclined surface 2211. The first driving block 223 is provided with a guide inclined surface that matches the first driving inclined surface 2211 at the position corresponding to the first driving inclined surface 2211.

[0098] Specifically, the first traction member 212 of the first operating component 21 is connected to the first action component 22. The first operating component 21 can be connected to the first driving block 223 of the first action component 22 through the first traction member 212, so that the first driving block 223 slides along the direction of the groove of the first slide 2221. The specific direction is the axial direction of the connecting pipe 132, that is, the traction direction of the first traction member 212. One end of the first driving block 223 passes through the middle of the first locking tongue 221. Furthermore, the middle of the first locking tongue 221 is provided with a first driving inclined surface 2211. At the same time, the first driving block 223 is provided with a guide inclined surface that matches the first driving inclined surface 2211 at the position corresponding to the first driving inclined surface 2211. Therefore, it can be understood that when the first traction member 212 pulls the first driving block 223 upward in the first slide groove 2221, it drives the guide inclined surface that matches the first driving inclined surface 2211 to move upward, thereby causing the first driving inclined surface 2211 on the first locking tongue 221 to slide in the horizontal direction of the inclined surface. This causes the end of the first locking tongue 221 that extends out of the first outer shell 222 to retract into the first outer shell 222, and finally disengages the first locking tongue 221 from the snap hole 1331, thereby allowing the first action component 22 to slide in the telescopic tube 133.

[0099] It should be noted that, since a first elastic element 224 is provided between the first slide groove 2221 and the first driving block 223, it is conceivable that when the user operates the first operating component 21, it drives the first driving block 223 to move upward, thereby compressing the first elastic element 224, so that the first elastic element 224 stores the elastic potential energy of the reset. At the same time, a second elastic element 225 is provided between the first locking tongue 221 and the first outer shell 222. Therefore, when the user operates the first operating component 21, the first locking tongue 221 retracts and compresses the second elastic element 225, so that the second elastic element 225 stores the elastic potential energy of the reset. Due to the elastic potential energy of the first operating component 21, when the user releases the first operating component 21, the first latch 221 slides to the next engagement hole 1331. The first driving block 223 can rebound downwards under the reset action of the first elastic element 224, while the first latch 221 extends towards the first housing 222 under the reset action of the second elastic element 225. Alternatively, the first driving block 223 and the first latch 221 can be reset by the first driving inclined surface 2211 and the matching guide inclined surface, so that the first latch 221 engages in the next engagement hole 1331, while facilitating the user to control the first operating component 21 to control the next extension and retraction. At the same time as the first driving block 223 resets, the first traction element 212 can also pull the pressing block 211 to reset it.

[0100] It should be noted that both the first elastic element 224 and the second elastic element 225 are springs, or they can be elastic rubber parts, etc. It should also be noted that, in order to allow the pressing block 211 to quickly reset, an eighth elastic element (not shown in the figure) can be provided on the side of the pressing block 211 that abuts against the tube 13. One end of the eighth elastic element abuts against the inner side of the inner pressing block 211, while the other end abuts against the outer side of the tube 13. Thus, when the user releases the pressing block 211, it can be reset via the eighth elastic element.

[0101] Furthermore, in some embodiments of the present invention, the first actuating component 22 further includes a first limiting pin 226, which is disposed on the first housing 222 and passes through the first limiting oblong hole 2231 of the first driving block 223. Since one end of the first driving block 223 passes through the middle of the first latch 221, and the extension and retraction of the first latch 221 are achieved by the inclined driving method, in order to ensure that the first driving block 223 slides in the middle of the first latch 221 and to prevent the first driving block 223 from falling out of the first latch 221, a first limiting pin 226 is provided on the first housing 222. At the same time, the first limiting pin 226 passes through the first limiting oblong hole 2231 of the first driving block 223, thus restricting the first driving block 223 to the middle of the first latch 221.

[0102] Reference Figure 6In some embodiments of the present invention, the sleeve 311 is rotatably sleeved on the outside of the operating part 11, and the second operating component 31 includes two fixing blocks 312, a traction block 313 and a second traction member 314.

[0103] Two fixing blocks 312 are respectively disposed on the outer side of the U-shaped tube 131, and the two fixing blocks 312 are arranged opposite each other. The inner side of the fixing block 312 is attached to the outer side of the U-shaped tube 131. One of the fixing blocks 312 has a first slide rail 3121, which passes through the fixing block 312. The traction block 313 is slidably disposed in the first slide rail 3121. The upper end of the traction block 313 is provided with a first protrusion 3131, which is located on the first guide inside the sleeve 311. In the rail (not shown in the figure), the rotating sleeve 311 drives the first protrusion 3131 to slide along the direction of the first guide rail; the second traction member 314 is set in the pipe inside the pipe fitting 13. One end of the second traction member 314 is connected to one end of the traction block 313, and the other end of the second traction member 314 is connected to the second action component 32. The rotating sleeve 311 drives the traction block 313 to move, and the traction block 313 drives the second traction member 314 to pull the locking block 3231 of the second action component 32.

[0104] As can be seen from the previous embodiments, the execution unit 12 is provided on one or both sides of the operation unit 11, so correspondingly, the traction block 313 can also be provided with one or two blocks. This embodiment takes the example of having one execution unit 12 on one side of the operation unit 11 to further illustrate the second operation component 31:

[0105] To facilitate the sliding of the traction block 313 to drive the second traction member 314, fixing blocks 312 are provided on the upper and lower sides of the U-shaped tube 131. A first slide rail 3121 for sliding the traction block 313 is provided on the fixing block 312, and the direction of the first slide rail 3121 is the traction direction of the second traction member 314. In this embodiment, only one traction block 313 slides within the first slide rail 3121. Therefore, the first protrusion 3131 at the upper end of the traction block 313 is located in the first guide rail inside the sleeve 311. Since the sleeve 311 rotates around the central axis of the U-shaped tube 131, the first guide rail is spiral-shaped. Therefore, when the sleeve 311 rotates, the first protrusion 3131 at the upper end of the traction block 313 can slide in the first guide rail. However, the traction block 313 is restricted in the first slide groove 2221. Therefore, the traction block 313 slides along the direction of the first slide groove 2221, thereby driving the second traction member 314 to pull the second action component 32.

[0106] In other embodiments of the present invention, execution units 12 are provided on both sides of the operation unit 11, so correspondingly, two traction blocks 313 can also be provided. In this embodiment, two traction blocks 313 are provided, and both traction blocks 313 are slidably disposed in the first slide rail 3121. The first protrusions 3131 are both located in the first guide rail inside the sleeve 311. Rotating the sleeve 311 causes the first protrusions 3131 to slide along the direction of the first guide rail, and the two traction blocks 313 can slide relative to each other in the first slide rail 3121. Correspondingly, two second traction members 314 are provided. One end of the second traction member 314 is respectively connected to the two opposite ends of the traction blocks 313, and the other end of the second traction member 314 is respectively connected to the second action components 32 on both sides. Rotating the sleeve 311 causes the traction blocks 313 to move, and the traction blocks 313 cause the second traction members 314 to pull the locking block 3231 of the second action component 32.

[0107] As can be seen from the embodiment described above with only one traction block 313, when two traction blocks 313 are provided, the first guide rail inside the sleeve 311 can be provided with two threaded tracks with opposite helical directions, or it can be a guide ramp with opposite directions. Therefore, it can be understood that when the sleeve 311 rotates, it drives the first guide rail of the two threaded tracks with opposite helical directions to rotate, which in turn drives the first protrusion 3131 to slide relative to each other in the first guide rail, thereby driving the two traction blocks 313 to move relative to each other. And the traction blocks 313 sliding towards each other can drive the traction of the second action components 32 in the two actuators 12.

[0108] Furthermore, in some embodiments of the present invention, one traction block 313 is provided with a guide hole 3132, and the other traction block 313 is provided with a guide post 3133. A seventh elastic element (not shown in the figure) is sleeved on the outer side of the guide post 3133. One end of the seventh elastic element abuts against the bottom of the guide hole 3132, and the other end of the seventh elastic element abuts against the traction block 313. The guide post 3133 can be inserted into the guide hole 3132. When the two traction blocks 313 move relative to each other, the traction block 313 with the guide post 3133 drives the guide post 3133 to insert into the other traction block 313 with the guide hole 3132. This can prevent the two traction blocks 313 from flipping over, which would be detrimental to the cooperation and transmission between the first protrusion 3131 and the first guide rail. At the same time, the elastic potential energy stored in the seventh elastic element can be used for reset, which then acts on the sleeve 311 to make it rotate and reset, so as to facilitate the next rotation and folding.

[0109] Reference Figures 9 to 12Furthermore, in some embodiments of the present invention, the second action component 32 further includes a first unlocking component 321, a linkage component 322, and a second unlocking component 323. The first unlocking component 321 is disposed at one end of the connecting tube 132 and located in the telescopic tube 133, and includes a second locking tongue 3211. The linkage component 322 is slidably disposed in the telescopic tube 133 and located at the end of the telescopic tube 133 away from the connecting tube 132. The first unlocking component 321 is connected to the linkage component 322 through the second locking tongue 3211, and the first unlocking component 321 is used to drive the linkage component 322 to move. The second unlocking component 323 is disposed at the end of the telescopic tube 133 and is connected to the linkage component 322. The second unlocking component 323 includes a locking block 3231 and a second locking groove 3232a. The linkage component 322 drives the locking block 3231 to engage in the second locking groove 3232a so that the telescopic tube 133 can be flipped.

[0110] Specifically, when the user controls the first operating component 21, the connecting tube 132 can slide within the telescopic tube 133, so the first unlocking member 321 located at the end of the connecting tube 132 can slide within the telescopic tube 133. When the handle structure needs to retract, the connecting tube 132 slides towards the linkage member 322 during the extension and retraction process until the second locking tongue 3211 on the first unlocking member 321 engages with the linkage member 322; and the second unlocking member 323 is located at the end of the telescopic tube 133 and is connected to the linkage member 322. Therefore, it can be conceivable that the second operating component 31 drives the second traction member 314 to pull the first unlocking member 321, and the first unlocking member 321 can then engage with the linkage member 322 via the second locking tongue 3211, and by engaging with the linkage member 322, it drives the second unlocking member 323 connected to the linkage member 322. Since the second unlocking component 323 includes a snap-fit ​​block 3231 and a second snap-fit ​​groove 3232a, the first unlocking component 321 slides towards the end of the connecting tube 132 away from the installation position 2 under the traction of the second traction member 314, thereby driving the linkage component 322 away from the installation position 2. The linkage component 322 can then drive the second unlocking component 323, which can then drive the snap-fit ​​block 3231 to disengage from the first snap-fit ​​groove 2a and snap into the second snap-fit ​​groove 3232a, so that the snap-fit ​​block 3231 is freed from the constraint of the first snap-fit ​​groove 2a at the installation position 2 and is accommodated in the second snap-fit ​​groove 3232a at one end of the telescopic tube 133. Finally, the telescopic tube 133 can be freed from the constraint of the installation position 2 and can be flipped.

[0111] Reference Figures 7 to 10In some embodiments of the present invention, specifically, the first unlocking component 321 includes: a second outer shell 3212, a second driving block 3213, and a locking tongue sleeve 3215. The second outer shell 3212 is disposed at one end of the connecting pipe 132 and inserted into the telescopic pipe 133. A second sliding groove 3212a is provided inside the second outer shell 3212, and a second driving inclined surface 3212b is provided on the inner side of the second outer shell 3212. The second driving block 3213 is slidably disposed in the second sliding groove 3212a. A third elastic member 3214 is disposed between the second driving block 3213 and the second outer shell 3212. The third elastic member 3214 is located in the second sliding groove 3212a, with one end abutting against one end of the second driving block 3213 and the other end abutting against the inner wall of the second sliding groove 3212a. The second driving block 3213 is connected to the second operating component 31. The second operating component 31 drives the second driving block 3213 to slide in the second slide groove 3212a; the locking tongue sleeve 3215 is slidably disposed in the second driving block 3213, and the locking tongue sleeve 3215 is disposed through the second driving block 3213. A fourth elastic member 3216 is disposed between the locking tongue sleeve 3215 and the second driving block 3213. The fourth elastic member 3216 is located inside the second driving block 3213. One end of the fourth elastic member 3216 abuts against the locking tongue sleeve 3215, and the other end of the fourth elastic member 3216 abuts against the inside of the second driving block 3213. The outside of the locking tongue sleeve 3215 is provided with a guide slope that cooperates with the second driving slope 3212b. A second protrusion provided at one end of the locking tongue sleeve 3215 can be inserted into the linkage component 322.

[0112] Specifically, the second drive block 3213 is connected to the second operating component 31, that is, one end of the second traction member 314 in the second operating component 31 is connected to the second drive block 3213. The second traction member 314 can pull the second drive block 3213 to slide up and down in the second slide groove 3212a in the second housing 3212, specifically in the axial direction of the connecting pipe 132, i.e., the traction direction of the second traction member 314. A locking tongue sleeve 3215 is provided in the second drive block 3213, allowing it to slide up and down. It should be noted that a second driving inclined surface 3212b is provided on the inner side of the second housing 3212, and at the corresponding position, a guide inclined surface is provided on the outer side of the locking tongue sleeve 3215 to cooperate with the second driving inclined surface 3212b. The second driving inclined surface 3212b and the guide inclined surface can cooperate to abut against each other. When the second driving block 3213 moves the locking tongue sleeve 3215 upward, the locking tongue sleeve 3215 can be pushed outward of the second housing through the second driving inclined surface 3212b, thereby pushing the second locking tongue 3211 to the outside of the second housing 3212, which facilitates the second locking tongue 3211 to engage with the linkage member 322. It should be noted that in some embodiments, the outer side of the locking tongue sleeve 3215 is provided with a protrusion that can act as the second locking tongue 3211 to engage with the linkage member 322, thereby achieving the engagement.

[0113] It should also be noted that a third elastic element 3214 is provided between the second driving block 3213 and the second outer shell 3212. The third elastic element 3214 is located in the second sliding groove 3212a. One end of the third elastic element 3214 abuts against one end of the second driving block 3213, and the other end of the third elastic element 3214 abuts against the inner wall of the second sliding groove 3212a. Therefore, when the second driving block 3213 slides upward, it can compress the third elastic element 3214, so that the third elastic element 3214 stores the elastic potential energy for reset. At the same time, the locking tongue sleeve 3215 and A fourth elastic element 3216 is provided between the second driving blocks 3213. The fourth elastic element 3216 is located inside the second driving block 3213. One end of the fourth elastic element 3216 abuts against the locking tongue sleeve 3215, and the other end of the fourth elastic element 3216 abuts against the inside of the second driving block 3213. When the second driving block 3213 slides upward, the locking tongue sleeve 3215 is pushed outward by the second driving inclined surface 3212b. At the same time, the locking tongue sleeve 3215 compresses the fourth elastic element 3216, so that the fourth elastic element 3216 stores the elastic potential energy for reset. Therefore, when the user releases the second operating component 31, the third elastic element 3214 and the fourth elastic element 3216 can rebound, thereby causing the second driving block 3213 to slide downwards, and the locking tongue sleeve 3215, driven by the fourth elastic element 3216, slides towards the inside of the second outer shell 3212, that is, the second locking tongue 3211 retracts into the second outer shell 3212, thereby achieving the disconnection from the linkage component 322.

[0114] Furthermore, referring to Figure 8 In other embodiments of the present invention, the second latch 3211 is slidably disposed in the latch sleeve 3215, and the second latch 3211 and the latch sleeve 3215 are separable. A fifth elastic member 3217 can be provided between the second latch 3211 and the latch sleeve 3215. One end of the fifth elastic member 3217 abuts against the inside of the latch sleeve 3215, and the other end of the fifth elastic member 3217 abuts against the other end of the second latch 3211. A portion of the second latch 3211 protrudes beyond the outside of the second outer shell 3212, and the protruding portion of the second latch 3211 can be inserted into the linkage member 322. The fifth elastic member 3217 can push the second latch 3211 out to the outside of the latch sleeve 3215, ensuring that the second latch 3211 can be engaged with the linkage member 322.

[0115] It should be noted that the third elastic element 3214, the fourth elastic element 3216, and the fifth elastic element 3217 mentioned above can all be springs or elastic rubber parts. Similar to the first elastic element 224 and the second elastic element 225, no specific limitations are made in this embodiment.

[0116] Reference Figure 8 In some embodiments of the present invention, the first unlocking member 321 further includes a second limiting pin, which is disposed on the second driving block 3213 and passes through the second limiting oblong hole 3215a of the latch sleeve 3215. The first unlocking member 321 also includes a third limiting pin 3219, which is disposed on the second latch 3211 and passes through the third limiting oblong hole of the latch sleeve 3215. Similar to the principle of the first limiting pin 226 and the first limiting oblong hole 2231, the second limiting pin is set on the second driving block 3213 and passes through the second limiting oblong hole 3215a of the locking tongue sleeve 3215 to prevent the locking tongue sleeve 3215 from disengaging from the second driving block 3213. The third limiting pin 3219 is set on the second locking tongue 3211 and passes through the third limiting oblong hole of the locking tongue sleeve 3215 to prevent the second locking tongue 3211 from disengaging from the locking tongue sleeve 3215.

[0117] Reference Figures 9 to 10In some embodiments of the present invention, a locking hole 3221 is further provided at one end of the linkage member 322, and a second locking tongue 3211 can be inserted into the locking hole 3221 to engage with one end of the linkage member 322. Since the second locking tongue 3211 engages with the locking hole 3221 of the linkage member 322, the second traction member 314 can drive the linkage member 322 to slide within the telescopic tube 133 via the first unlocking member 321. Therefore, it can be understood that a second slide rail is provided inside the telescopic tube 133, and the linkage member 322 slides within the second slide rail. The second slide rail prevents the linkage member 322 from rotating within the telescopic tube 133, which would hinder engagement with the second locking tongue 3211 fixed in the first unlocking member 321.

[0118] Furthermore, in some embodiments of the present invention, the linkage member 322 further includes a fourth limiting pin 3222, which is disposed on the telescopic tube 133 and passes through the fourth limiting oblong hole 3223 of the linkage member 322. The fourth limiting pin 3222 can restrict the linkage member 322 to one end near the telescopic tube 133, thus ensuring the connection between the linkage member 322 and the second unlocking member 323.

[0119] Reference Figures 10 to 12 In some embodiments of the present invention, the second unlocking member 323 further includes: a third housing 3232, a support frame 3234, and a third traction member 3235. The third housing 3232 is disposed at one end of the telescopic tube 133 and located on one side of the installation position 2. The third housing 3232 is rotatably disposed on one side of the installation position 2. A second snap-fit ​​groove 3232a is provided inside the third housing 3232, the shape of which matches the shape of the snap-fit ​​block 3231. The support frame 3234 snaps onto the inside of the third housing 3232. The snap-fit ​​block 3231 is located on one side of the support frame 3234. A sixth elastic member 3236 is provided between the support frame 3234 and the snap-fit ​​block 3231. The sixth elastic member 3236... One end of the sixth elastic member 3236 abuts against the support frame 3234, and the other end of the sixth elastic member 3236 abuts against the snap-fit ​​block 3231; the third traction member 3235 is disposed in the third housing 3232 and wound around the support frame 3234, one end of the third traction member 3235 is disposed on the linkage member 322, and the other end of the third traction member 3235 is connected to the snap-fit ​​block 3231, and the linkage member 322 drives the snap-fit ​​block 3231 to snap into the second snap-fit ​​groove 3232a through the third traction member 3235; wherein, part of the snap-fit ​​block 3231 snaps into the first snap-fit ​​groove 2a of the installation position 2.

[0120] Specifically, the third outer shell 3232 is disposed at one end of the telescopic tube 133 and located on one side of the installation position 2. The third outer shell 3232 is rotatably disposed on one side of the installation position 2, so the telescopic tube 133 can rotate with the third outer shell 3232 at the installation position 2, thereby realizing the folding of the handle structure. It should be noted that a second snap-fit ​​groove 3232a is provided on the inner side of the third outer shell 3232. The shape of the second snap-fit ​​groove 3232a matches the shape of the snap-fit ​​block 3231, so the snap-fit ​​block 3231 can be disposed in the second snap-fit ​​groove 3232a on the inner side of the third outer shell 3232. It should also be noted that part of the snap-fit ​​block 3231 is snapped into the first snap-fit ​​groove 2a of the installation position 2. Therefore, it can be understood that when the handle structure is locked, part of the locking block 3231 is engaged in the first locking groove 2a on the mounting position 2, and the other part of the locking block 3231 is engaged in the second locking groove 3232a. Thus, the locking block 3231 simultaneously engages the mounting position 2 and the third outer shell 3232, thereby fixing the third outer shell 3232, i.e., fixing the handle structure. When the second operating component 31 drives the second action component 32, the locking block 3231 can be disengaged from the first locking groove of the mounting position 2, so that the locking block 3231 is fully engaged in the second locking groove 3232a of the third outer shell 3232. That is, the locking connection between the third outer shell 3232 and the mounting position 2 is lost, thereby allowing the third outer shell 3232 and the mounting position 2 to be rotatably connected, and thus the handle structure can be flipped and closed.

[0121] More specifically, in order to drive the sliding of the latching block 3231 and move it between the first latching slot 2a and the second latching slot 3232a, the third traction member 3235 can be pulled by the linkage member 322 to move the latching block 3231. When the second traction member 314 in the second operating component 31 pulls the first unlocking member 321 in the second action component 32 to move, it will then drive the linkage member 322 to move through the second locking tongue 3211. Finally, the linkage member 322 pulls the latching block 3231 through the third traction member 3235, thereby changing the position of the latching block 3231.

[0122] It should be noted that a sixth elastic element 3236 is provided between the support frame 3234 and the locking block 3231. One end of the sixth elastic element 3236 abuts against the support frame 3234, and the other end abuts against the locking block 3231. Therefore, it can be understood that when the second operating component 31 is driven by the sleeve 311 to control the movement of the locking block 3231 of the second action component 32, the locking block 3231 is lifted, thereby compressing the space between the support frame 3234 and the locking block 3231. The sixth elastic element 3236 stores elastic potential energy for resetting the locking block 3231. Therefore, when the second operating component 31 is released, the locking block 3231 loses the effect of external force. Under the elastic potential energy, the sixth elastic element 3236 pushes the locking block 3231 out of the second locking groove 3232a in the third housing 3232, so that part of the locking block 3231 is re-locked back into the first locking groove 2a of the installation position 2, thereby locking the handle structure.

[0123] It should also be noted that the support frame 3234 provided between the snap-fit ​​block 3231 and the inner side of the third housing 3232 can support the third traction member 3235, thereby changing the traction direction of the third traction member 3235, and thus lifting the snap-fit ​​block 3231 so that the snap-fit ​​block 3231 can disengage from or snap into the first snap-fit ​​groove 2a of the installation position 2; in addition, the support frame 3234 can also abut against the sixth elastic member 3236, so that the snap-fit ​​block 3231 can be reset and snapped into the first snap-fit ​​groove 2a by the sixth elastic member 3236.

[0124] Furthermore, in some embodiments of the present invention, a second tensioning wheel 3234a is provided on the support frame 3234, and a third traction member 3235 is wound around the periphery of the second tensioning wheel 3234a. The second tensioning wheel 3234a is used to tension the third traction member 3235. The second tensioning wheel 3234a is consistent with the first tensioning wheel 213 in principle, both facilitating the winding of the traction portion 2114 of the traction member and facilitating the sliding of the traction portion 2114.

[0125] Reference Figure 6In some embodiments of the present invention, one of the fixing blocks 312 is also provided with a clearance hole 3122. That is, the fixing block 312 located on one side of the first operating component 21 is provided with a clearance hole 3122 for accommodating the pressing block 211. Moreover, the pressing block 211 includes an action part 2113 and a traction part 2114. The action part 2113 can be inserted into the sleeve 311. The action part 2113 is used for pressing by the user and is the outer part of the pressing block 211 mentioned above. The traction part 2114... 14 is provided in the sleeve 311. The end of the actuating part 2113 and the traction part 2114 that abut against each other is provided with a matching arc surface 2113a. Therefore, the actuating part 2113 and the traction part 2114 can be slidably connected relative to each other through the arc surface 2113a. Furthermore, the arc surface 2113a of the actuating part 2113 can fit against the outer surface of the fixing block 312. Pressing the actuating part 2113 will cause the traction part 2114 to be engaged in the clearance hole 3122. Therefore, it can be understood that when the user... When the actuating part 2113 of the pressing block 211 is pressed towards the inside of the pipe fitting 13, the actuating part 2113 pushes the traction part 2114 inward. Once pushed into place, the arc surface 2113a on the actuating part 2113 fits against the arc surface 2113a on the outside of the fixing block 312. Therefore, the actuating part 2113 and the fixing block 312 can slide relative to each other, while the traction part 2114 is completely accommodated in the clearance hole 3122 of the fixing block 312. Therefore, it can also be understood that when the user... Pressing the pressing block 211 allows the extension and retraction of the tube 13 of the handle body 1. At the same time, since the arc surface 2113a on the action part 2113 is in contact with the arc surface 2113a on the outside of the fixing block 312, the action part 2113 and the fixing block 312 can slide relative to each other. Only then can the sleeve 311 be rotated. The sleeve 311 can drive the action part 2113, which is inserted therein, to rotate around the center of the tube 13, thereby controlling the second action component 32 to fold the handle body 1.

[0126] When folding the handle structure, the user should first press the pressing block 211 into place to retract the tube 13 before rotating the sleeve 311. The sleeve 311 controls the second operating component 31 to control the second action component 32 to achieve the flipping and folding of the handle structure.

[0127] Furthermore, in some embodiments of the present invention, in order to prevent the sleeve 311 from shifting axially, a guide block 3123 can be provided on the fixed block 312, and a second guide rail 3111 matching the guide block 3123 is provided on the inner side of the sleeve 311. The guide block 3123 is disposed in the second guide rail 3111, and the sleeve 311 can rotate along the extending direction of the guide block 3123. When the sleeve 311 rotates, the axial shift of the sleeve 311's rotational position can be prevented by the guidance of the second guide rail 3111 and the cooperation of the guide block 3123.

[0128] Reference Figure 6 In some embodiments of the present invention, a rotating groove 3114 is provided at one end of the fixed cylinder 3112. The rotating groove 3114 is annular and surrounds the periphery of the fixed cylinder 3112. Rotating blocks 3113 are provided at both ends of the sleeve 311, and the rotating blocks 3113 are slidably disposed in the rotating groove 3114. When the sleeve 311 rotates, the rotating blocks 3113 rotate in the rotating groove 3114. Therefore, it can be understood that the rotating groove 3114 can limit the rotation angle of the sleeve 311 and prevent the sleeve 311 from excessively pulling the traction block 313, thereby damaging the second traction member 314.

[0129] According to a second aspect embodiment of the present invention, the trolley includes a handle structure as described in any of the embodiments of the first aspect. The trolley is provided with a mounting position 2, and the handle structure is rotatably mounted on the mounting position 2. The handle structure is telescopic and foldable onto the trolley, facilitating its unfolding and use as well as its folding and storage by the user.

[0130] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
