Description

Technical Field

[0001] The utility model relates to a handle quick adjustment structure, in particular to a handle quick adjustment structure for a hand-over bucket truck. Background Art

[0002] A dump truck is a special vehicle with a tiltable bucket for short-distance material transportation. A "bucket"-shaped container is installed on the body of the vehicle, which can be flipped over to facilitate unloading. It is suitable for short-distance transportation of various bulk materials such as sand, gravel, earth, coal, ore, etc. It usually has a mechanical bucket return function. During the construction process, hand-overturned dump trucks are generally used to transport the mixed cement mortar.

[0003] At present, a large number of hand-overturned dump trucks are used on construction sites. Due to the particularity of their structure, long handles are indispensable for hand-overturned dump trucks. However, when the truck is fully loaded and parked, the two long and strong handles often hinder people from walking. Especially when the truck is full of goods, an elevator cannot be used to transport the goods because the handles and the truck body are too long together, making it inconvenient for staff to use. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a handle quick adjustment structure for a hand-over bucket truck to solve the technical problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a quick adjustment structure of a handle for a hand-over dump truck, comprising a fixed plate and a rotating ring, a central axis is fixedly installed on one side of the fixed plate, and a gear plate is fixedly installed on one side of the central axis, a connecting rod is fixedly installed on one end of the rotating ring, and a limiting rod is movably installed in the connecting rod, a spring is fixedly installed on one end of the limiting rod, and a limiting groove is provided on one side of the limiting rod, and a limiting ring is movably installed on one end of the connecting rod.

[0006] By adopting the above technical solution, after the handle is adjusted to the desired position, the grip rod can be rotated again to re-limit and lock the position of the limit rod and the grip rod, thereby reducing the space required for the hand-over trolley during placement or transportation, which will not affect the normal use of the hand-over trolley. At the same time, it is adapted to the usage habits of the staff, has a relatively simple structure, and is easy to use.

[0007] The utility model is further configured that one side of the limiting ring is provided with an internal thread matched with the limiting groove, and one end of the limiting ring is fixedly installed with a clamping block.

[0008] By adopting the above technical solution and installing a clamping block, the limiting operation of the limiting rod is realized, so that the limiting groove releases or locks the position relationship between the limiting rod and the toothed disc according to the rotation angle of the limiting ring, thereby realizing multi-stage adjustment of the overall height of the handle.

[0009] The utility model is further configured that one end of the connecting rod is provided with an external thread matched with the internal thread, and one end of the connecting rod is provided with a through hole matched with the clamping block.

[0010] By adopting the above technical solution and providing a through hole, the rotation position of the limit ring is guided, which facilitates the limiting operation of the limit ring on the limit rod and avoids position deviation of the limit ring.

[0011] The utility model is further configured that a handle rod is movably mounted on one end of the connecting rod, a guide slot is provided on the inner side of the handle rod, and the rotating ring is movably sleeved on the central axis.

[0012] By adopting the above technical solution, a guide slot is provided, which can be used in conjunction with a limit ring to facilitate multi-end adjustable limit locking of the handle rod when the limit ring expands its diameter, thereby allowing the handle of the hand-over bucket truck to be appropriately adjusted in different locations.

[0013] The utility model is further configured that protrusions matching with the guide slots are fixedly installed at both ends of the limit ring, and one end of the limit rod is configured with a cone angle matching with the toothed disc.

[0014] By adopting the above technical solution and installing the protrusion, the movement of the handle rod is guided and limited, thereby achieving stable horizontal telescopic displacement of the handle rod along the protrusion.

[0015] The utility model is further configured that a gap is arranged on the side of the limiting ring, and the side of the limiting ring can expand outward, and one end of the limiting ring is configured with a cone angle matched with the guide slot.

[0016] By adopting the above technical solution and providing a gap, a certain amount of room is provided for the change in caliber caused by the rotation of the clamping block, thereby preventing the limit ring from being locked and damaged by excessive squeezing and contraction force of the grip rod.

[0017] In summary, the utility model mainly has the following beneficial effects:

[0018] The utility model provides a limit ring, a limit rod, a spring, etc., and by rotating the handle rod, the limit ring rotates along the external thread and shrinks the diameter, thereby releasing the limit on the handle rod, so that the handle rod can be telescopically operated under the action of the protrusion, and the clamping block moves along the limit groove to release the limit on the limit rod, so that the handle rod can be rotated around the central axis, and then can be reset again under the action of the spring. When the handle is adjusted to the position, the handle rod can be rotated again to limit and lock the position of the limit rod and the handle rod again, thereby reducing the space position of the hand-over bucket cart during the placement process or transportation, and will not affect the normal use of the hand-over bucket cart. At the same time, it adapts to the usage habits of the staff, has a relatively simple structure, and is easy to use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0025] The following describes an embodiment of the utility model based on its overall structure.

[0026] A handle quick adjustment structure for a hand-over bucket truck, such as Figure 1-4As shown, it includes a fixed plate 1 and a rotating ring 2. A central axis 14 is fixedly installed on one side of the fixed plate 1, and a toothed disk 5 is fixedly installed on one side of the central axis 14. A connecting rod 4 is fixedly installed on one end of the rotating ring 2, and a limiting rod 11 is movably installed in the connecting rod 4. A spring 10 is fixedly installed on one end of the limiting rod 11, and a limiting groove 12 is provided on one side of the limiting rod 11. A limiting ring 7 is movably installed on one end of the connecting rod 4. The handle rod 3 is rotated to make the limiting ring 7 rotate along the external thread 8 and shrink the caliber, thereby releasing the limit on the handle rod 3, so that the handle rod 3 can be horizontally telescopic under the action of the protrusion 16 to adjust the handle length. At the same time, the block 13 moves along the limiting groove 12 to release the limit on the limiting rod 11, so that the limiting rod 11 can be movable, and the cone angle end of the handle rod 3 slides in cooperation with the toothed disk 5, so that the handle rod 3 can be rotated with the central axis 14 as the axis.

[0027] See also Figure 4 An internal thread 15 matching the limiting groove 12 is provided on one side of the limiting ring 7, and a clamping block 13 is fixedly installed at one end of the limiting ring 7. By installing the clamping block 13, the limiting operation of the limiting rod 11 is realized, so that the limiting groove 12 releases or locks the position relationship between the limiting rod 11 and the toothed disc 5 according to the rotation angle of the limiting ring 7, thereby realizing multi-stage adjustment of the overall height of the handle.

[0028] See also Figure 4 One end of the connecting rod 4 is provided with an external thread 8 that matches the internal thread 15, and one end of the connecting rod 4 is provided with a through hole 9 that matches the block 13. By providing the through hole 9, the rotation position of the limit ring 7 is guided, which facilitates the limiting operation of the limit ring 7 on the limit rod 11 and avoids position displacement of the limit ring 7.

[0029] See also Figure 2 A handle rod 3 is movably mounted at one end of the connecting rod 4, and a guide slot 6 is provided on the inner side of the handle rod 3. The rotating ring 2 is movably sleeved on the central axis 14. By providing the guide slot 6, the guide slot 6 can be used in conjunction with the limit ring 7 to facilitate multi-end adjustable limit locking of the handle rod 3 when the caliber of the limit ring 7 expands, thereby allowing the handle of the hand-over bucket car to be appropriately adjusted in different venues.

[0030] See also Figure 3 , protrusions 16 matching the guide slots 6 are fixedly installed at both ends of the limit ring 7, and one end of the limit rod 11 is set with a cone angle matching the toothed disc 5. By installing the protrusion 16, it plays a guiding and limiting role for the movement of the handle rod 3, thereby realizing stable horizontal telescopic displacement of the handle rod 3 along the protrusion 16.

[0031] See also Figure 4A gap is set on the side of the limit ring 7, and the side of the limit ring 7 can expand outward. One end of the limit ring 7 is set with a cone angle that matches the guide slot 6. By setting the gap, a certain amount of activity space is given to the caliber change caused by the rotation of the block 13, thereby avoiding the limit ring 7 from being locked and damaged by excessive squeezing and contraction force of the handle rod 3.

[0032] When the handle is in a suitable position, the handle bar 3 can be rotated in the opposite direction, so that the limiting ring 7 can be locked to the limiting rod 11 again through the blocking block 13, and the limiting ring 7 can be expanded through the internal thread 15 and the external thread 8, so that the limiting ring 7 can be locked to the limiting rod 11 again through the blocking block 13, and the internal thread 15 can be locked to the limiting rod 11 again through the external thread 8, so that the limiting ring 7 can be expanded through the internal thread 15 and the external thread 8, so that the limiting ring 7 can be locked to the limiting rod 11 through the blocking block 13, and the limiting ring 7 can be expanded through the internal thread 15 and the external thread 8, so that the limiting ring 7 can be locked to the limiting rod 11 tightly through the blocking block 13.

[0033] Although an embodiment of the utility model has been shown and described, this specific embodiment is merely an explanation of the utility model and is not a limitation of the utility model. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contributions as needed without departing from the principles and purpose of the utility model.
