Description

Technical Field

[0001] The utility model relates to the technical field of sawhorses, in particular to a movable and foldable sawhorse for a bevel cutting machine. Background Art

[0002] When processing strips of wood, it is often necessary to fix the wood to prevent it from sliding during cutting and improve safety. Generally, sawhorses are large in size, heavy in weight, and take up more space, making them inconvenient to move and carry. Therefore, a new solution is proposed to solve this problem. Summary of the invention

[0003] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a movable and foldable miter saw frame, which can be folded by movable connection between a first connecting frame group, a second connecting frame group and a third connecting frame group, so as to facilitate movement and carrying.

[0004] The above-mentioned technical purpose of the utility model is achieved through the following technical solutions: a movable and foldable miter cutting machine saw frame, comprising a supporting frame and supporting plates arranged on both sides of the supporting frame and fixedly connected to the supporting frame, the supporting plates comprising a first connecting frame arranged on the right side of the supporting frame and a second connecting frame arranged on the left side of the supporting frame, the first connecting frame is rotatably connected with a first linkage frame group, the second connecting frame is rotatably connected with a second linkage frame group, the second linkage frame group is movably connected with a third linkage frame group, the second linkage frame group is rotatably folded toward one end of the supporting frame, one end of the second linkage frame group is provided with a telescopic section, and the third linkage frame group is rotatably folded toward one end of the second linkage frame group.

[0005] By adopting the above technical scheme, when folding, the first linkage frame group is folded by rotating the first linkage frame group clockwise toward one end of the supporting platform until the first linkage frame group is in a parallel state with the supporting platform. The second linkage frame group rotatably connected to the first linkage frame group follows the rotation of the first linkage frame group. Since one end of the second linkage frame group is restricted by the second connecting frame, the other end of the second linkage frame group is folded counterclockwise toward the supporting platform. The second linkage frame group is provided with a retractable section to cooperate with the adjustable rotation of the second linkage frame group. Finally, the third linkage frame group rotatably connected to the second linkage frame group is folded counterclockwise, so that the sawhorse is folded and stored as a whole. After folding, the locking card rotatably connected on the second linkage frame group is matched and locked with the positioning column fixedly connected to the first linkage frame group to further limit the connection between the first linkage frame group and the second linkage frame group. The elastic lock buckle rotatably connected on the third linkage frame group is used to limit the second linkage frame group and the third linkage frame group, thereby realizing the locking of the folded state of the sawhorse.

[0006] The utility model is further configured as follows: an adjustment plate is fixedly connected to the second linkage frame group, a plurality of adjustment holes are opened on the adjustment plate in a circumferential array, and connecting through holes corresponding to the adjustment holes are opened through the third linkage frame group, and the adjustment holes and the connecting through holes are fixed by bolts.

[0007] By adopting the above technical solution, the position of the adjustment hole is adjusted by the unfolded or folded state between the second linkage frame group and the third linkage frame group, and the adjustment hole and the connecting through hole are connected by bolts to lock and fix the state of the second linkage frame group and the third linkage frame group.

[0008] The utility model is further configured as follows: a locking card is rotatably provided on the second linkage frame group, a locking slot is provided on the locking card plate, a positioning column is fixedly connected to the first linkage frame group by bolts, and the locking card matches the locking slot.

[0009] By adopting the above technical solution, when the first linkage frame group, the second linkage frame group and the third linkage frame group are in a folded state, the locking clamping plate arranged on the second linkage frame group is rotated so that the locking clamping plate on the second linkage frame group is locked with the bolts correspondingly arranged on the first linkage frame group through the locking groove, thereby restraining the sawhorse in the folded state.

[0010] The utility model is further configured as follows: an elastic lock buckle is rotatably connected to the third linkage frame assembly.

[0011] By adopting the above technical solution, when the first linkage frame group, the second linkage frame group and the third linkage frame group are in a folded state, the position of the third linkage frame group and the second linkage frame group fixed by bolts is restricted by adjusting the position of the elastic lock, so that the folded sawhorse has better stability and is not easy to fall apart.

[0012] The utility model is further configured as follows: auxiliary brackets are arranged at both ends of the support plate, support handrails are slidably connected to the auxiliary brackets, and the support handrails and the auxiliary brackets are fixed by locking bolts.

[0013] The utility model is further configured as follows: a moving wheel is arranged at one end of the second linkage frame assembly away from the second connecting frame.

[0014] By adopting the above technical solution, the movable wheels are provided to facilitate the movement of the sawhorse in an unfolded or folded state as a whole, thereby providing mobility convenience.

[0015] The utility model is further configured as follows: a handle is provided on one end of the second linkage frame assembly which is away from the second connecting frame and extends upward.

[0016] By adopting the above technical solution, the handle is provided to facilitate the operator to move the sawhorse.

[0017] The utility model is further configured as follows: a supporting foot is arranged at the bottom of the third linkage frame group.

[0018] By adopting the above technical solution, the support feet are arranged to increase the friction between the third linkage frame group and the ground, so as to improve the support stability of the overall structure.

[0019] The utility model is further configured as follows: reinforcing ribs are arranged between the first linkage frame group, the second linkage frame group and the third linkage frame group.

[0020] By adopting the above technical solution, the reinforcing ribs are mainly used to improve the supporting strength of the first linkage frame group, the second linkage frame group and the third linkage frame group.

[0021] The utility model is further configured as follows: at least one set of fixing parts is arranged on the support plate, the fixing parts include a fixing frame connected with the support plate bolts, a fixing plate is fixedly connected to the first linkage frame, and the fixing plate and the fixing frame are connected by a latch.

[0022] By adopting the above technical solution, the setting of the fixing piece plays a role of limiting the sawhorse in a supporting state.

[0023] In summary, the utility model has the following beneficial effects:

[0024] 1. The sawhorse can be folded by movable connection between the first connecting frame group, the second connecting frame group and the third connecting frame group, so as to facilitate movement and carrying;

[0025] 2. A movable wheel is provided at one end of the second linkage frame assembly away from the second connecting frame.
