Description

Technical Field

[0001] The utility model relates to the technical field of motor mounting structures, in particular to a fall-resistant motor mounting structure for a scissors machine. Background Art

[0002] The scissors machine is a handheld electric tool that uses an electric motor as its power and drives the working head through a transmission mechanism to perform shearing operations. The scissors machine consists of a motor, a casing, a reduction gearbox, an eccentric shaft-connecting rod mechanism, a switch, a non-rewirable plug and a cutter. During use, the worker will connect the power supply to the scissors machine, take the scissors machine and put the items to be cut into the scissors machine, and press the switch to cut the target.

[0003] However, since the scissors machine has many internal parts and is heavy, workers will put it in a convenient position after use in their daily work. Workers may accidentally touch the scissors machine during work, causing the scissors machine to fall. Due to its own mass, it will generate a large impact force when it falls to the ground, causing irreversible damage to the motor inside the scissors machine. To this end, we propose a motor installation structure for scissors machine that is resistant to falling. Utility Model Content

[0004] The utility model aims to provide a fall-resistant motor mounting structure for a scissors machine, which solves the problem of significant damage to the scissors machine motor when the scissors machine falls accidentally.

[0005] The utility model achieves the above-mentioned purpose through the following technical solutions:

[0006] A fall-resistant motor mounting structure for a scissors machine, the mounting structure being arranged between the scissors machine motor and its external shell, and characterized in that the mounting structure comprises two groups of buffer assemblies symmetrically arranged on the inner wall of the shell, the buffer assembly comprising a first spring fixedly arranged on the inner wall of the shell, the end of the first spring being fixedly connected to a push plate, vertical plates being respectively arranged at both ends of the push plate, the two vertical plates being fixedly connected to the inner wall of the shell, the upper ends of the two vertical plates being arranged with inclined plates, the surfaces of the two inclined plates being slidably connected with arc plates, and the arc plates in the two groups of buffer assemblies being in extrusion contact with the scissors machine motor from opposite sides.

[0007] A further improvement is that the surfaces of the two vertical plates are provided with sliding grooves, and the two ends of the push plate are arranged in the sliding grooves.

[0008] A further improvement is that rectangular grooves are provided inside both ends of the arc plate, the inner wall of the rectangular groove is provided with a second spring, one end of the second spring is fixedly connected to a first trapezoidal block, and the first trapezoidal block is slidably connected to the inner wall of the arc plate.

[0009] A further improvement is that a second trapezoidal block is fixedly provided on the inner wall of the arc plate, a trapezoidal groove is provided on the surface of the first trapezoidal block, the second trapezoidal block is used to be inserted into the trapezoidal groove to generate resistance to the sliding of the first trapezoidal block, and the trapezoidal groove is slidably connected to the second trapezoidal block.

[0010] A further improvement is that the second spring and the first trapezoidal block are located on a side of the inner wall surface of the rectangular groove close to the second trapezoidal block, and a gap is left between a side of the first trapezoidal block away from the second trapezoidal block and the inner wall of the rectangular groove.

[0011] A further improvement is that an inner wall of the inclined plate is provided with an inclined groove, and the first trapezoidal block is slidably connected to the surface of the inclined groove.

[0012] The beneficial effect of the utility model is that the motor mounting structure of the scissors machine can reduce the impact force on the scissors machine motor. When the scissors machine falls accidentally, the scissors machine motor can move downward together with the arc plate to absorb the kinetic energy of the scissors machine motor when it falls, thereby reducing the damage to the scissors machine motor when the scissors machine falls, which is beneficial to maintaining the normal operation of the scissors machine motor when it is impacted and improving the fall resistance of the scissors machine motor.

DETAILED DESCRIPTION

[0018] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0019] Combination Figure 1-4As shown, a fall-resistant motor mounting structure for scissors machine is provided, the mounting structure is arranged between the scissors machine motor 2 and its external shell 1, and is characterized in that the mounting structure includes two groups of buffer components 3 symmetrically arranged on the inner wall of the shell 1, the buffer component 3 includes a first spring 4 fixedly arranged on the inner wall of the shell 1, the end of the first spring 4 is fixedly connected with a push plate 5, the two ends of the push plate 5 are respectively provided with vertical plates 6, the two vertical plates 6 are fixedly connected to the inner wall of the shell 1, the upper ends of the two vertical plates 6 are provided with inclined plates 7, the surfaces of the two inclined plates 7 are slidably connected with arc plates 8, and the arc plates 8 in the two groups of buffer components 3 are squeezed and contacted with the scissors machine motor 2 from opposite sides.

[0020] In actual use, when a worker uses the scissors machine in daily work and accidentally causes the scissors machine to fall from a height, the scissors machine shell will first contact the ground and generate a corresponding impact force, and the scissors machine motor 2 inside the shell 1 will also be impacted. At this time, the scissors machine motor 2 will continue to move downward on the inner wall of the shell 1 and squeeze the push plate 5 and the first spring 4, thereby leaving space for buffering when the scissors machine motor 2 falls, slowing down the kinetic energy of the scissors machine motor 2, and dispersing the impact force received by the scissors machine motor 2, thereby protecting the scissors machine from damage to the mounting structure of the scissors machine motor 2 on the inner wall of the shell 1 when the scissors machine falls, which is beneficial to enhancing the stability of the scissors machine motor 2 and the mounting structure inside the scissors machine.

[0021] Preferably, the surfaces of the two vertical plates 6 are provided with sliding grooves 9, and the two ends of the push plate 5 are arranged in the sliding grooves 9, so that the push plate 5 can move in the sliding grooves 9 on the surfaces of the two vertical plates 6, limiting the movement range of the push plate 5, and at the same time keeping the first spring 4 in a compressed state, so that the push plate 5 remains stationary when it does not move in the sliding grooves 9.

[0022] Preferably, rectangular grooves 10 are provided inside both ends of the arc plate 8, and the inner wall of the rectangular groove 10 is provided with a second spring 11. One end of the second spring 11 is fixedly connected to a first trapezoidal block 12, and the first trapezoidal block 12 is slidably connected to the inner wall of the arc plate 8. When the scissors machine does not fall, the first trapezoidal block 12 and the second trapezoidal block 13 remain in a stationary state, and the second spring 11 is in a compressed state. When the scissors machine falls, the first trapezoidal block 12 will move along the inner wall of the rectangular groove 10 and squeeze the second spring 11, thereby absorbing the kinetic energy of the scissors machine motor 2 and reducing the impact force of the scissors machine motor 2.

[0023] Preferably, a second trapezoidal block 13 is fixedly provided on the inner wall of the arc plate 8, and a trapezoidal groove 14 is provided on the surface of the first trapezoidal block 12. The second trapezoidal block 13 is used to be inserted into the trapezoidal groove 14 to generate resistance to the sliding of the first trapezoidal block 12. The trapezoidal groove 14 is slidably connected to the second trapezoidal block 13. When the scissors machine falls, the scissors machine motor 2 drives the arc plate 8 to move downward, so that the first trapezoidal block 12 slides into the trapezoidal groove 14, and at the same time, the trapezoidal groove 14 and the second trapezoidal block 13 are squeezed against each other. When the impact force of the scissors machine falling is greater than the friction force between the trapezoidal groove 14 and the second trapezoidal block 13, the first trapezoidal block 12 drives the trapezoidal groove 14 to slide on the surface of the second trapezoidal block 13, so that the first trapezoidal block 12 moves into the trapezoidal groove 14 and squeezes the second spring 11. Similarly, under the reverse push of the second spring 11, the second trapezoidal block 13 contacts the trapezoidal groove 14 again.

[0024] Preferably, the second spring 11 and the first trapezoidal block 12 are located on the side of the inner wall surface of the rectangular groove 10 close to the second trapezoidal block 13, and a gap is left between the side of the first trapezoidal block 12 away from the second trapezoidal block 13 and the inner wall of the rectangular groove 10, so that when the trapezoidal blocks move along the surface of the second trapezoidal block 13, the first trapezoidal block 12 continues to move toward the inside of the rectangular groove 10 while moving above the second trapezoidal block 13.

[0025] Preferably, an inclined groove 15 is provided on the inner wall of the inclined plate 7, and the first trapezoidal block 12 is slidably connected to the surface of the inclined groove 15, so that the arc plate 8 can move along the surface of the inclined groove 15 and limit the movement range of the arc plate 8. At the same time, the inclined surface of the first trapezoidal block 12 will be squeezed against the surface of the inclined groove 15, so that the first trapezoidal block 12 moves toward the inside of the rectangular groove 10.

[0026] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
