Description

Technical Field

[0001] The utility model relates to the technical field of blade installation structures, in particular to a blade quick installation structure which is easy to disassemble. Background Art

[0002] The rotary blade mounting structure is used for cutting equipment such as cutting machines or lawn mowers. The traditional rotary blade mounting structure consists of a gear box, a lower pressure piece and an upper pressure piece. Since the lower pressure piece is rotatably connected to the mounting plate on the gear box, when the staff installs or removes the blade, the staff needs to fix the lower pressure piece to prevent the lower pressure piece from rotating when the rotary blade is installed or removed, so that the rotary blade can be removed from between the lower pressure piece and the upper pressure piece. Since the lower pressure piece needs to be fixed, the staff has to fix the lower pressure piece with one hand through the fixing rod and remove it with the other hand, which makes the staff easy to get injured when disassembling or installing, and makes the installation or removal of the rotary blade very inconvenient. Utility Model Content

[0003] The purpose of the present invention is to provide a quick installation structure for a blade that is easy to disassemble, so as to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a quick installation structure for a blade that is easy to disassemble, comprising:

[0006] A rotating rod, the rotating rod being rotatably connected to the working head gear box mounting plate;

[0007] A gear box dust cover, wherein the gear box dust cover is sleeved with a limiting ring;

[0008] A spring clamp, the spring clamp being arranged on one side inside the gear box dust cover;

[0009] A pressing member, the pressing member being engaged with the rotating rod;

[0010] An upper pressing piece, the top of which is arranged on the lower pressing piece;

[0011] A protective cover is arranged on the top of the outer surface of the rotating rod.

[0012] By adopting the above technical solution, the staff places the rotating blade between the lower pressure piece and the upper pressure piece, and then the user clamps the lower pressure piece through the spring clamp to prevent the lower pressure piece from rotating. Then the staff fixes the lower pressure piece, the rotating blade and the upper pressure piece between the gear box dust cover and the protective cover through the nut. If the staff needs to remove the rotating blade, the staff can also limit the rotation of the lower pressure piece by pressing the spring clamp to prevent the lower pressure piece from rotating with the nut, which makes it easier for the staff to remove the nut from the rotating rod, so that the rotating blade can be removed.

[0013] Preferably, the spring clamp includes a mounting member, a pressing block is slidably mounted on one side of the mounting member, a clamping block is mounted on the other side of the pressing block, and a spring is mounted on the outer surface of the clamping block.

[0014] By adopting the above technical solution, the staff presses the pressing block to drive the spring to squeeze, and the pressing block can drive the card block to move, so that the card block extends. When the pressing block is not squeezed, the rebound of the spring can drive the card block to move in the opposite direction.

[0015] Preferably, a snap ring is provided at the middle position of the top inner portion of the pressing member, a slot is provided at the bottom of the outer surface of the rotating rod, and the pressing member is snap-connected with the rotating rod via the snap ring and the slot.

[0016] By adopting the above technical solution, the pressing member rotates with the rotation of the rotating rod through the clamping ring and the clamping groove, thereby driving the rotation of the rotating blade.

[0017] Preferably, the lower pressing member, the upper pressing member and the protective cover are sleeved with the rotating rod.

[0018] Preferably, a thread is provided on the top of the outer surface of the rotating rod, and the rotating rod is threadably connected to the nut through the thread.

[0019] By adopting the above technical solution, the gear box dust cover, the lower pressing piece, the upper pressing piece and the protective cover can be restricted between the working head gear box mounting plate and the nut through the nut.

[0020] Preferably, a circular hole is provided on one side of the pressing member, a groove is provided on one side of the top of the limiting ring, and the clamping block is clamped with the pressing member through the circular hole and the groove.

[0021] By adopting the above technical solution, the circular hole on the pressing part is prevented from rotating by the clamping block on the spring clamp, and the groove on the limiting ring can further support the clamping block pressed out on the spring clamp, thereby preventing the spring clamp from being damaged due to excessive force applied by the staff.

[0022] Compared with the prior art, the beneficial effects of the present invention are: the blade quick installation structure that is easy to disassemble is equipped with a spring clip inside the gear box dust cover. When the user disassembles or installs the rotating blade, he only needs to align the hole on the pressing part with the spring clip, and the staff can manually disassemble or install the rotating blade. Since there is no need to use a fixing rod, the staff can avoid injury when installing or disassembling the rotating blade, and the installation or disassembly of the rotating blade is convenient.

Then the staff fixes the lower pressure piece 6, the rotating blade and the upper pressure piece 7 between the gear box dust cover 4 and the protective cover 8 through the nut 9. If the staff needs to remove the rotating blade, the staff can also limit the rotation of the lower pressure piece 6 by pressing the spring clamp 5 to prevent the lower pressure piece 6 from rotating with the nut 9, making it easier for the staff to remove the nut 9 from the rotating rod 3, so that the rotating blade can be removed.

[0039] In this embodiment, the spring clamp 5 includes a mounting member 50, a pressing block 51 is slidably installed on one side of the mounting member 50, a clamping block 52 is installed on the other side of the pressing block 51, and a spring 53 is installed on the outer surface of the clamping block 52. The staff presses the pressing block 51 to drive the spring 53 to be squeezed, and the pressing block 51 can drive the clamping block 52 to move, so that the clamping block 52 extends. When the pressing block 51 is not squeezed, the rebound of the spring 53 can drive the clamping block 52 to move in the opposite direction.

[0040] In this embodiment, a retaining ring is provided at the middle position of the top inner portion of the lower pressure member 6, and a retaining groove is provided at the bottom of the outer surface of the rotating rod 3. The lower pressure member 6 is connected to the rotating rod 3 through the retaining ring and the retaining groove.
