[0030] The following description of the present invention, with reference to the accompanying drawings, is provided to facilitate a more comprehensive understanding of the various embodiments of the present invention as defined in the claims and their equivalents. The description includes various specific details to assist understanding, but these details should be construed as merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications may be made to the various embodiments described herein without departing from the scope and spirit of the present invention.

[0031] In the description of the present invention, descriptions of directions, such as up, down, front, back, left, right, etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as a limitation on the present invention.

[0032] It will be understood that when one element (e.g., a first element) is “connected” to another element (e.g., a second element), the element may be directly connected to the other element or an intervening element (e.g., a third element) may be present between the element and the other element.

[0033] The embodiment of the present invention provides a retractable handle, such as Figures 1-5 As shown, the telescopic handle includes a hollow outer rod 410, a hollow inner rod 420, a movable member 440 and a limit assembly 450. The outer rod 410 is sleeved on the outer side of the lower end of the inner rod 420 and can slide along the length direction of the inner rod 420. The length of the entire telescopic handle is mainly determined by the outer rod 410 and the inner rod 420. Therefore, when the outer rod 410 and the inner rod 420 slide relative to each other, the length of the entire telescopic handle changes. When the two slide in a direction away from each other, as shown in FIG. Figure 1 As shown, the outer rod 410 and the inner rod 420 are unfolded, and the entire retractable handle is long enough for normal use by the user. When the two slide toward each other, as shown in FIG. Figure 2 As shown, the outer rod 410 and the inner rod 420 are relatively retracted, and the length of the entire retractable handle is shorter, which can reduce space occupation and facilitate storage and carrying.

[0034] The upper end of the inner rod 420 is connected to a grip 430 for the user to grasp. The user can grasp the grip 430 to pull or push the entire handle. The movable member 440 and the limit assembly 450 are both located inside the inner rod 420. The movable member 440 includes a toggle member 441 at its upper end and a transmission member 442 at its lower end. A portion of the toggle member 441 extends outside the inner rod 420 and can move along the length of the inner rod 420. Naturally, the inner rod 420 needs to have a corresponding slot for the toggle member 441 to extend. Since the toggle member 441 extends outside the inner rod 420, it is convenient for the user to operate the toggle member 441 from the outside.

[0035] The limiting assembly 450 includes a limiting member 451 and an elastic member 452. A through-hole 401 is provided on the side of the inner rod 420 to match the limiting member 451. A plurality of limiting holes 411 are provided on the side of the outer rod 410, distributed along the length of the inner rod 420 and matching the limiting member 451. The plurality of limiting holes 411 are provided, which is equivalent to forming multiple gears, allowing the limiting member 451 to be retracted within the through-hole 401. That is, the limiting member 451 can extend out of the through-hole 401 to extend to the outside of the inner rod 420, or retract into the through-hole 401 so as not to protrude from the inner rod 420. The elastic member 452 abuts against the limiting member 451 and applies an elastic force to the limiting member 451. This force causes the limiting member 451 to remain in a locked state extending out of the through-hole 401. When the limiting hole 411 is aligned with the through-hole 401, the limiting member 451 extending out of the through-hole 401 can be inserted into the limiting hole 411, thereby restricting the inner rod 420 from sliding relative to the outer rod 410, thereby locking the inner rod 420 and the outer rod 410 together. When the toggle member 441 moves along the length of the inner rod 420, the transmission member 442 can drive the limiting member 451 to overcome the force of the elastic member 452 and move to an unlocked state retracted into the limiting hole 451. The limiting member 451 no longer protrudes from the inner rod 420 and does not restrict the inner rod 420 from sliding relative to the outer rod 410.

[0036] When using the handle of this embodiment, the user can manually move the toggle member 441, thereby driving the transmission member 442 to move, and the transmission member 442 then drives the limiting member 451 to retract the limiting hole 451, and the inner rod 420 can slide relative to the outer rod 410. The user can expand or contract the entire handle according to his or her needs. When the inner rod 420 and the outer rod 410 have been adjusted to a suitable position, the limiting hole 411 is connected to the through-hole 401, and then the toggle member 441 is released. Under the action of the elastic device 452, the limiting member 451 extends outward and is inserted into the limiting hole 411, and the inner rod 420 and the outer rod 410 can maintain the adjusted position and are difficult to slide easily, thereby ensuring that the user can use the handle normally.

[0037] In some embodiments, as Figures 4-6 As shown, the transmission member 442 is provided with a first inclined surface 443, and the limiting member 451 is provided with a second inclined surface 453 adapted to the first inclined surface 443. The heights of the first inclined surface 443 and the second inclined surface 453 gradually increase in the direction in which the limiting member 451 extends from the through-hole 401. The first inclined surface 443 is located below and abuts against the second inclined surface 453.

[0038] When the entire movable part 440 moves upward, the first inclined surface 443 slides along the second inclined surface 453, which generates a lateral thrust. This thrust enables the limiting part 451 to overcome the force of the elastic device 452 and shrink inward, and the limiting part 451 can be retracted into the through hole 401.

[0039] Further, the transmission member 442 is provided with a transmission groove 444, both side walls of the transmission groove 444 are provided with a first protrusion 445, and the first inclined surface 443 is arranged on the top of the first protrusion 445. The limiting member 451 is arranged in the transmission groove 444, both sides of the limiting member 451 are provided with a second protrusion 454, and the second inclined surface 453 is arranged on the bottom of the second protrusion 454.

[0040] Since the limiting member 451 is arranged in the transmission groove 444, the side wall of the transmission groove 444 can laterally limit the limiting member 451, and during the movement, the limiting member 451 will not tilt to the left and right sides, thereby ensuring that the limiting member 451 can be stretched and contracted along the through hole 401. Meanwhile, the first inclined surface 443 and the second inclined surface 453 are both provided with two, and when the entire movable member 440 moves upward, a horizontal thrust can be generated from both sides of the limiting member 451, so that the limiting member 451 can be kept balanced, and further prevent the limiting member 451 from tilting.

[0041] In some embodiments, as shown in Figures 4-6 The transmission member 442 is provided with a limiting through groove 446 extending along the length direction of the inner rod 420, and the limiting assembly 450 further includes a limiting plate 455 which is inserted into the limiting through groove 446 and can move along the limiting through groove 446. When the transmission member 442 moves along the length direction of the inner rod 420, if the limiting plate 455 abuts against the lower end or the upper end of the limiting through groove 446, the limiting plate 455 will limit the transmission member 442 from continuing to move, which limits the stroke of the transmission member 442 moving along the length direction of the inner rod 420, avoids the transmission member 442 from moving upward or downward too far to be separated from the limiting assembly 450, and ensures that the entire mechanism can work stably and for a long time.

[0042] Further, the limiting assembly 450 further includes a backstop 456 connected with the limiting plate 455, and the backstop 456 is located at the back side of the limiting member 451 in the direction in which the limiting member 451 extends out of the through hole 401. Both ends of the elastic member 452 abut against the backstop 456 and the limiting member 451 respectively, so as to provide an elastic force to the limiting member 451.

[0043] The limiting plate 455 and the backstop 456 can be integrally formed and can be substantially in the shape of an "L". The elastic member 452 can be a spring, a spring sheet or other elastic member.

[0044] In some embodiments, as shown in Figures 4-6 The limiting assembly 450 includes a mounting seat 457 which is fixed in the inner rod 420. The mounting seat 457 is provided with a mounting groove, and the limiting member 451 and the elastic member 452 are arranged in the mounting groove, and the transmission member 442 extends into the mounting groove.

[0045] The mounting seat 457 provides necessary mounting space for the limiting piece 451 and the elastic device 452, so that the limiting piece 451, the elastic device 452 and the transmission piece 442 can be organically assembled together, instead of being in a discrete state. Meanwhile, the limiting piece 451 and the elastic device 452 can be mounted in the mounting groove first, the transmission piece 442 is inserted into the mounting groove, and then the mounting seat 457 is fixed into the inner rod 420, so as to facilitate overall assembly.

[0046] The mounting seat 457 can be fixed in the inner rod 420 through various detachable modes such as buckle connection and screw fixing, so as to facilitate later maintenance.

[0047] Further, the limiting plate 455 and the back plate 456 of the above-mentioned embodiments are also mounted in the mounting groove.

[0048] In some embodiments, as shown in Figure 3 , Figure 4 and Figure 7 , the inner rod 420 includes an inner rod body 421 and a sleeve joint 422, the sleeve joint 422 is sleeved and fixed at the upper end of the inner rod body 421, the outer rod 410 is sleeved outside the lower end of the inner rod body 421 and can slide along the length direction of the inner rod body 421, the movable piece 440 and the limiting assembly 450 are both arranged inside the inner rod body 421. The side surfaces of the inner rod body 421 and the sleeve joint 422 are both provided with grooves 423 which are in abutment with each other, the poking piece 441 passes through the grooves 423 of the inner rod body 421 and the sleeve joint 422 and extends to the outside of the sleeve joint 422, so that the user can operate the poking piece 441 outside. The sleeve joint 422 can block the upper end opening of the inner rod body 421, avoiding the exposure of the movable piece 440, and plays a protective role for the movable piece 440, and meanwhile, the sleeve joint 422 provides space for the mounting of the holding piece 430.

[0049] In some embodiments, the sleeve joint 422 has a clamping hole 424, the holding piece 430 is a holding rod clamped in the clamping hole 424, and the holding rod can extend in the transverse direction, so as to facilitate the user to grasp.

[0050] The embodiments of the utility model also provide an outdoor cart, as shown in Figure 8 , comprising a cart body 10 and the telescopic handle of any one of the above-mentioned embodiments, and the outer rod 410 is mounted on the cart body 10. When the user needs to use the handle, the inner rod 420 can be pulled out upwards to increase the overall length of the handle, so as to facilitate the user to grasp. When the user does not use the outdoor cart, the inner rod 420 can be retracted downwards to reduce the overall length of the handle, so as to reduce the space occupation, and facilitate storage and carrying.
