DETAILED DESCRIPTION

[0026] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0027] First embodiment

[0028] Please refer to Figure 1 , Figure 2 , Figure 3 ,in, Figure 1 A schematic structural diagram of a first embodiment of an adjustable handlebar for a flatbed vehicle provided by the utility model; Figure 2 for Figure 1 The schematic diagram of the top view of the rotating rod shown; Figure 3 for Figure 1 The enlarged schematic diagram of part A is shown. An adjustable handlebar for a flatbed vehicle comprises: a bottom plate 1;

[0029] Rollers 12, the rollers 12 are rotatably connected to two ends of both sides of the bottom plate 1;

[0030] Support rods 2, the support rods 2 are fixedly mounted on both sides of one end of the top of the bottom plate, the inner thread of the support rod 2 is connected with a threaded rod 21, the top of the outer side of the threaded rod 21 is rotatably connected with a fixing frame 3, and the top of the threaded rod 21 is fixedly mounted with a worm gear 22;

[0031] The rotating rod 4 is arranged on one side of the fixed frame 3, and a worm 45 is fixedly installed on one end of the rotating rod 4. One end of the worm 45 is rotatably connected to one side of the inner side of the fixed frame 3, and the worm 45 is meshed with one side of the worm wheel 22.

[0032] A surrounding plate 11 is fixedly mounted on the top of the base plate 1 .

[0033] A rubber sleeve 41 is fixedly mounted on the middle portion of the outer side surface of the rotating rod 4 .

[0034] Rotating discs 42 are fixedly mounted on both ends of the outer side surface of the rotating rod 4 , and a plurality of rotating handles 43 are fixedly mounted on the sides of the two rotating discs 42 .

[0035] A locking screw 44 is threadedly connected to the inner portion of the rotating disk 42 , and one end of the locking screw 44 is attached to one side of the fixing frame 3 .

[0036] By providing a surrounding plate 11 on the top of the bottom plate 1, when in use, it can play a role of limiting the position of items placed on the top of the bottom plate 1;

[0037] The arrangement of the rotating disk 42 and the rotating handle 43 facilitates the user to rotate the rotating rod 4 during use, and the rubber pad 41 is arranged on the outer side of the rotating rod 4 to increase the friction between the rotating rod 4 and the user's hand.

[0038] By threading the locking screw 44 inside the turntable 42, the height of the handlebar can be limited after it is adjusted to a suitable height, thereby preventing the user from accidentally touching the handlebar and causing the height of the handlebar to move again.

[0039] The working principle of the adjustable handlebar for a flatbed vehicle provided by the utility model is as follows:

[0040] When in use, when the handlebar height of the flatbed cart needs to be adjusted, the user can rotate the locking screw 44 to make one end of the locking screw 44 move away from the fixed frame 3, and then the user rotates the handle 43 to make the handle 43 drive the rotating rod 4 to rotate through the turntable 42, so that the rotating rod 4 drives the worm 45 to rotate, and then the worm 45 and the worm wheel 22 are engaged, thereby driving the worm wheel 22 to rotate, and the worm wheel 22 drives the threaded rod 21 to rotate, so that the threaded rod 21 is threadedly connected inside the support rod 2, thereby adjusting the height of the handlebar. After adjusting to the appropriate height, the user rotates the locking screw 44 to make one end of the locking screw 44 press against the fixed frame 3, thereby limiting the turntable 42 and the rotating rod 4.

[0041] Compared with the related art, the adjustable handlebar for a flatbed vehicle provided by the utility model has the following features:

[0042] Beneficial effects:

[0043] Through the cooperation of structures such as the support rod 2, the threaded rod 21, the worm gear 22, the fixed frame 3, the rotating rod 4 and the worm 45, when using it, the user only needs to rotate the rotating rod 4 to make the threaded rod 21 threadedly connected inside the support rod 2, so as to adjust the height of the handlebar. The user does not need to bend down to operate, and the need for multiple people to cooperate in the operation is avoided, thereby facilitating the use of the user.

[0044] Second embodiment

The second embodiment is only a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0046] Specifically, the difference of the adjustable handlebar for a flatbed cart provided in the second embodiment of the present application is that, in the adjustable handlebar for a flatbed cart, a side plate 5 is fixedly installed at one end of the base plate 1, a threaded sleeve 51 is fixedly installed inside the side plate 5, and a threaded rod 53 is threadedly connected to the inner side surface of the threaded sleeve 51.

[0047] A crank handle 52 is fixedly mounted on the top of the threaded rod 53 , and a pad 54 is fixedly mounted on the bottom of the threaded rod 53 .

[0048] The working principle of the adjustable handlebar for a flatbed vehicle provided by the utility model is as follows:

[0049] After the device is moved to a suitable position, when loading or unloading items, the user can turn the crank 52 to make the crank 52 drive the threaded rod 53 to rotate, so that the threaded rod 53 is threadedly connected to the inner side of the threaded sleeve 51, and then the threaded rod 53 is moved downward, thereby driving the pad 54 to move downward and contact the ground, thereby limiting the device.

[0050] Compared with the related art, the adjustable handlebar for a flatbed vehicle provided by the utility model has the following features:

[0051] Beneficial effects:

[0052] By cooperating with each other through structures such as the side plate 5, the threaded sleeve 51, the crank handle 52, the threaded rod 53 and the pad 54, when in use, the threaded rod 53 is threadedly connected to the inner side of the threaded sleeve 51 and then moves downward, so that the device can be limited to avoid movement when loading and unloading objects.
