Description

Technical Field

[0001] This utility model relates to the technical field of household tools, and in particular to a foldable frame with a handle. Background Technology

[0002] For existing folding frames with handles, when the user holds the two handles, there is no effective support between the two handles. This causes the two handles to shift when the user moves or when the fingers apply uneven force to the handles, resulting in the folding frame shaking and discomfort when holding it, especially when it is necessary to carry and walk for a long time.

[0003] In view of this, the inventors specifically designed a foldable frame with a handle, which led to this invention. Utility Model Content

[0004] The purpose of this invention is to provide a foldable frame with a handle, which can reduce the deviation of the handle in the hand, thereby reducing the shaking of the foldable frame and improving the comfort of holding it.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A foldable frame with handles includes a frame, two horizontal plates, two side plates, a base plate, locking components, and a pair of hand-held components. The two horizontal plates are symmetrically arranged along the long axis of the frame, with their upper ends rotatably connected to the lower end of the frame. The two side plates are symmetrically arranged on the sides of the frame, with their upper ends rotatably connected to the lower end of the frame. The lower ends of the horizontal plates and side plates are respectively inserted into the base plate. The inner sides of the locking components pass through both ends of the sides of the base plate, and the ends of the locking components are threadedly connected to the inside of the horizontal plates. The hand-held components are symmetrically arranged on the upper end of the frame, with their lower ends rotatably connected to the frame. Each hand-held component includes a U-shaped rotating frame and support blocks. The lower ends of the rotating frame extend downwards on both sides and are rotatably connected to the frame. The support blocks are fixedly arranged on the horizontal portion of the rotating frame, and the mutual support between the support blocks restricts the upper end of the rotating frame from shifting.

[0007] Furthermore, the lower end of the frame is provided with a protruding edge that extends downward around the edge, and the protruding edge is used to restrict the upper ends of the horizontal plate and the side plate from rotating outward; the lower end of the frame inside the protruding edge is provided with a number of protrusions that extend downward around the circumference; the side of the protrusions is provided with fixing components, there is a certain height difference between the four fixing components, and the two ends of the fixing components are respectively embedded in the horizontal plate or the side plate.

[0008] Furthermore, the fixing assembly includes two connecting posts and a spring; the spring is located between the two connecting posts and its two ends are fixedly connected to the inner side of the connecting posts respectively; the outer side of the connecting posts is embedded in a horizontal plate or side plate.

[0009] Furthermore, the upper ends of the horizontal plate and the side plate are provided with a number of protrusions at intervals, and the protrusions can be embedded between the protrusions; the outer sides of the connecting columns are respectively embedded into the sides of the protrusions.

[0010] Furthermore, locking holes are provided at the lower ends of both sides of the horizontal plate, and the locking holes are used to make threaded connections with the inner side of the locking component after passing through the base plate.

[0011] Furthermore, the support block is elongated.

[0012] Furthermore, the lower end of the support block has a quarter-circle grip portion and an extension portion on the upper inner side of the grip portion; the outer side of the extension portion is fixedly connected to the rotating frame; the inner sides of the support blocks abut against each other.

[0013] Furthermore, the long edge of the base plate is provided with a transverse groove for the lower end of the horizontal plate to be inserted; the side edge of the base plate is provided with a lateral groove for the lower end of the side plate to be inserted; and the two ends of the side edge of the base plate are provided with through holes for the locking element to pass through, the inside of the through holes communicating with the transverse groove.

[0014] After adopting the above technical solution, the present invention has the following beneficial effects:

[0015] The core innovation of this invention lies in the design of a more stable handheld component. The "U"-shaped rotating frame and support block structure reduce the possibility of handle shifting in the hand, thereby reducing uneven force distribution and resulting in shifting. This reduces swaying of the folding frame during transport and improves user comfort. Specifically, the folding frame consists of a frame, horizontal plate, side plates, a base plate, locking components, and the handheld component. The key to the handheld component is its rotating frame and support block design. The support blocks are fixed to the rotating frame, and when the two support blocks abut against each other, they effectively limit the upper part of the rotating frame from shifting.
