Technical Field

[0001] This utility model relates to the field of power tool technology, specifically to an electric pick that facilitates the disassembly and assembly of the motor. Background Technology

[0002] Currently, the durability of large electric hammer motors is a common problem in the market, requiring motor replacement after a certain period of use. Traditionally, replacing the motor involves opening the left handle, loosening the switch screw, pulling the switch lead out of the handle to separate it, loosening the Allen screw, removing the rear cover of the housing, and finally removing the motor housing from the casing to access the motor that needs replacement.

[0003] The aforementioned technical method involves a complex disassembly and assembly process. The motor is installed inside the housing, with the outer casing and handle sequentially mounted on the outside. To remove the motor, the handle and outer casing must be disassembled first. During installation, after inserting the motor, the outer casing and handle must be reassembled. This results in a cumbersome disassembly and assembly process, adding unnecessary component removal and assembly steps, wasting time, and reducing work efficiency. Utility Model Content

Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-4This utility model provides an embodiment of an electric pick that facilitates motor disassembly and assembly, comprising: a housing 1, a motor compartment 2 at the bottom of the housing 1, a fixing frame 3 and a motor 4 at the bottom of the motor compartment 2, and a base 7 at the bottom of the motor compartment 2; a knob 5 rotatably disposed at the middle position of the top of both sides of the base 7, and a locking structure 6 disposed at the middle position of the top of one side of the base 7, the knob 5 being connected to the locking structure 6, the user can release the locking structure 6 by rotating the knob 5, allowing the user to remove the base 7 from the bottom of the motor compartment 2, and then release the engagement between the motor compartment 2 and the fixing frame 3 by rotating the fixing frame 3, thus disassembling the motor 4 from the motor compartment 2, allowing the user to quickly replace the motor 4, and finally, the user can reverse the operation to install the motor 4 inside the motor compartment 2.

[0031] In this embodiment, a locking block is provided at the middle position of both ends inside the motor compartment 2. The fixing frame 3 is sleeved with the motor 4. The motor compartment 2 is locked with the fixing frame 3 through the locking block. The user can lock the fixing frame 3 inside the motor compartment 2 by using the locking block. The user can release the locking between the motor compartment 2 and the fixing frame 3 by rotating the fixing frame 3, so that the fixing frame 3 can be removed from the motor compartment 2, thereby allowing the motor 4 to be disassembled.

[0032] In this embodiment, slots are provided at the middle position of the bottom of both sides of the motor compartment 2. The size of the slots on the motor compartment 2 is compatible with the size of the knob 5. The slots on the motor compartment 2 facilitate the installation of the motor compartment 2 and the base 7.

[0033] In this embodiment, the motor compartment 2 and the base 7 are connected together. Both ends of the motor compartment 2 are provided with abutments. The top of the base 7 overlaps with the abutments. The abutments on the motor compartment 2 cooperate with the locking structure 6 on the base 7 so that the base 7 can be locked on the motor compartment 2 and prevent the base 7 from falling off the motor compartment 2.

[0034] In this embodiment, the locking structure 6 includes a bidirectional threaded rod 60. Movable parts 61 are provided on both sides of the outer surface of the bidirectional threaded rod 60. Connecting rods 62 are rotatably provided at both ends of the movable parts 61. A first mounting plate 63 and a second mounting plate 64 are provided at the end of the connecting rod 62 away from the movable parts 61. When the user rotates the bidirectional threaded rod 60, the movable parts 61 move, thereby moving the connecting rods 62, so that the first mounting plate 63 and the second mounting plate 64 can move within the base 7. The locking structure 6 cooperates with the abutment block to ensure that the base 7 can be stably and firmly installed on the motor compartment 2.

[0035] In this embodiment, a threaded hole is provided on one side of the movable part 61, and the movable part 61 is threadedly connected to the bidirectional threaded rod 60 through the threaded hole. Movable parts are provided at both ends of the movable part 61 and at the end of the connecting rod 62 away from the movable part 61. When the bidirectional threaded rod 60 rotates, the movable part 61 can move on the bidirectional threaded rod 60 through the threaded hole.

[0036] In this embodiment, both sides of the first mounting plate 63 and the second mounting plate 64 near the moving part 61 are provided with sliding grooves. The sliding grooves of the first mounting plate 63 and the second mounting plate 64 are provided with sliding rods. The movable part of the connecting rod 62 is provided with a sliding hole on one side. The movable part of the connecting rod 62 is slidably connected to the sliding rod of the first mounting plate 63 and the second mounting plate 64 through the sliding hole. When the moving part 61 moves along the bidirectional threaded rod 60, the connecting rod 62 can move accordingly. Through the cooperation of the movable part, the first mounting plate 63 and the second mounting plate 64 can move within the base 7.

[0037] In this embodiment, both ends of the top of the connecting rod 62 are provided with connecting holes, and the connecting rod 62 is rotatably connected to the movable part through the connecting holes. Both ends of both sides of the base 7 are provided with sliding grooves, and both sides of the first plate 63 and the second plate 64 are provided with sliders. The first plate 63 and the second plate 64 are slidably connected to the base 7 through the sliders and sliding grooves. The sliding groove on the base 7 cooperates with the sliders on the first plate 63 and the second plate 64, so that the first plate 63 and the second plate 64 can move within the base 7, and the sliding groove on the base 7 can play a limiting role.

[0038] Working principle: By rotating knob 5, the user rotates the bidirectional threaded rod 60, which in turn moves the moving part 61 within the bidirectional threaded rod 60, thereby moving the connecting rod 62. This allows the first mounting plate 63 and the second mounting plate 64 to move within the base 7. The locking structure 6 engages with the stop block, facilitating easy assembly and disassembly between the base 7 and the motor compartment 2. Then, by rotating the fixing bracket 3, the user can release the latch between the motor compartment 2 and the fixing bracket 3, allowing the motor 4 to be removed from the motor compartment 2 for quick replacement. Finally, the user can reverse the operation to install the motor 4 inside the motor compartment 2.
