Description

TECHNICAL FIELD

[0001] The utility model relates to a heavy-duty cart folding beveling machine frame. BACKGROUND

[0002] The beveling machine frame is mainly used for profile processing, such as wood, board and the like. During profile processing, the profile needs to be fixed first, and the profile is more stable during cutting, thereby improving production quality and ensuring safety. Generally, the beveling machine frame is large in size, and occupies a large space.

[0003] The present application provides a foldable and stable structure to solve this problem. SUMMARY

[0004] In view of the deficiencies in the prior art, the utility model discloses a heavy-duty cart folding beveling machine frame, which realizes stable storage of the overall structure through the cooperation of the first folding frame and the second folding frame arranged in a staggered manner and rotationally connected and the fixing assembly.

[0005] The utility model discloses a heavy-duty cart folding beveling machine frame, which comprises a profile fixing frame, a fixing plate frame clamped on the profile fixing frame, an extension frame arranged below the profile fixing frame, and a first folding frame and a second folding frame arranged in a staggered manner below the extension frame. The first folding frame and the second folding frame are rotationally connected. A fixing rod is arranged between the first folding frames. A first supporting rod and a fixing assembly fixed on the first supporting rod and matched with the fixing rod are arranged between the second folding frames. The fixing assembly comprises a group of connecting pieces. A T-shaped fixing rod is rotationally arranged between the connecting pieces. One end of the T-shaped fixing rod is provided with a screw thread and is fixed by a nut. A torsional spring is sleeved on the T-shaped fixing rod. One end of the torsional spring is fixedly connected with the inner wall of the connecting piece. The other end of the torsional spring is fixedly connected with a fixing hook piece. The fixing hook piece is rotationally connected with the T-shaped fixing rod. The fixing hook piece is clamped with the fixing rod.

[0006] Through the above technical scheme, the fixing plate frame is clamped on the profile fixing frame by a buckle connection to fix the profile. The extension frame is arranged to extend. The profile fixing frame is matched with the profile fixing frame to support and fix profiles of various sizes. When the first folding frame and the second folding frame are in a storage state, the fixing hook piece arranged on the second folding frame is clamped on the fixing rod arranged between the first folding frames to connect the first folding frame and the second folding frame. When the storage state is released, the tail end of the fixing hook piece is stressed to swing downward around the T-shaped fixing rod as the center axis. Under the action of the lever, the head of the fixing hook piece swings upward to lift up, thereby realizing disengagement from the fixing rod and releasing the connection between the fixing rod and the fixing assembly. The overall structure is stable in the storage state, and the occupied space is reduced.

[0007] The present invention is further configured such that a foot pedal is provided on the fixed hook plate.

[0008] By adopting the above technical solution, when the connection between the fixing rod and the fixing component between the first folding frames is released, by stepping on the pedal, the tail end of the fixing hook plate is subjected to force and swings downward around the T-shaped fixing rod as the center axis. Under the action of the lever, the head of the fixing hook plate swings upward and is lifted to disengage from the fixing rod, thereby releasing the connection between the fixing rod and the fixing component.

[0009] The present invention is further configured such that a limiting piece is fixedly connected to the connecting piece.

[0010] By adopting the above technical solution, the position of the limiting piece is used to limit the position of the front end of the fixing hook piece and to support the position of the fixing hook piece.

[0011] The present invention is further configured such that: a support frame is provided at the bottom of the first folding frame, the support frame is U-shaped, and a protective corner piece is provided at the bottom of the support frame.

[0012] By adopting the above technical solution, the upright frame is arranged in a U-shape, so that when the first folding frame and the second folding frame are in the storage state, the upright frame can play a supporting role, thereby improving the placement stability of the overall structure.

[0013] The present invention is further configured such that the profile fixing frame and the extension frame are slidably connected.

[0014] The present invention is further configured such that: the profile fixing frame is provided with symmetrical sliding grooves on both sides, the extension frame includes a sliding rod and a handrail that are slidably connected to the sliding grooves, and the profile fixing frame is provided with a positioning bolt for fixing.

[0015] By adopting the above technical solution, the sliding rod can slide in the slide groove by unscrewing the positioning bolts on the profile fixing frame. According to the actual use, the sliding rod can slide out to both sides relative to the profile fixing frame. After sliding out, the positioning bolts are tightened again to fix the sliding rod. The sliding rod is cylindrical, which makes its surface smoother and reduces scratches.

[0016] In summary, this utility model has the following beneficial effects:

[0017] The first and second folding frames, which are arranged in an overlapping and rotatably connected manner, work together with a fixing component to achieve stable storage of the overall structure. Attached Figure Description
