[0032] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0033] like Figures 1-6 As shown, it illustrates a safety-type plastic base for household appliances in one embodiment of the present invention, comprising: a base plate 1, on which an installation groove 5 is provided, and two sets of fixing mechanisms 4 are slidably connected to the installation groove 5, the two sets of fixing mechanisms 4 being symmetrically arranged; by setting the fixing mechanisms 4, it is convenient to fix the bottom of the appliance, which is beneficial to maintaining the stability of the appliance;

[0034] Height adjustment mechanism 2 is fixedly connected to the four corners of the bottom end of the base plate 1. Each set of height adjustment mechanism 2 can be adjusted independently. Setting up height adjustment mechanism 2 helps to improve the stability of the base plate 1 and prevent the uneven ground from affecting the stability of electrical appliances.

[0035] The moving mechanism 3 is fixedly connected to the middle of the bottom end of the base plate 1, and the moving mechanism 3 is used to move the entire equipment;

[0036] The height adjustment mechanism 2 includes a housing 201, a threaded rod 202 threadedly connected to the housing 201, a support block rotatably connected to the bottom end of the threaded rod 202, and a U-shaped mounting plate 203 fixedly connected to the housing 201. By rotating the threaded rod 202, the threaded rod 202 can be moved along the housing 201 to adjust the height of the height adjustment mechanism 2.

[0037] Two sets of first reciprocating screws 205 are rotatably connected to the U-shaped mounting plate 203. Two sets of arc-shaped clamping blocks 208 are threadedly connected to each set of first reciprocating screws 205. The two sets of arc-shaped clamping blocks 208 are symmetrically arranged and slidably connected to the U-shaped mounting plate 203. The internal threads of the two sets of arc-shaped clamping blocks 208 are symmetrically arranged. By rotating the first reciprocating screws 205, the two sets of arc-shaped clamping blocks 208 are driven to move closer or further away from each other to fix the threaded rod 202, which helps to improve the stability of the threaded rod 202.

[0038] The front and rear ends of the U-shaped mounting plate 203 are respectively fixedly connected to telescopic sleeves 204. One end of the telescopic sleeve 204 passes through the U-shaped mounting plate 203 and is fixedly connected to the arc-shaped clamping block 208. The telescopic sleeve 204 is used to improve the stability of the movement of the arc-shaped clamping block 208.

[0039] Both sets of first reciprocating lead screws 205 are fixedly connected to sprockets 206, and both sets of sprockets 206 are meshed with chains 207 on their outer walls. One end of one set of first reciprocating lead screws 205 passes through a U-shaped mounting plate 203 and is fixedly connected to a torsion block. By rotating the torsion block, the first reciprocating lead screw 205 is driven to rotate. The rotation of the first reciprocating lead screw 205 drives the sprocket 206 to rotate. The sprocket 206 meshes with the chain 207 to rotate, so that the two sets of first reciprocating lead screws 205 rotate synchronously.

[0040] For example, such as Figure 4 As shown, rotating the torsion block drives the first reciprocating screw 205 to rotate, which in turn drives the sprocket 206 to rotate. The sprocket 206 meshes with the chain 207 to rotate, causing the two sets of first reciprocating screws 205 to rotate synchronously. This drives the two sets of arc-shaped clamps 208 to move closer or further apart to fix the threaded rod 202, which helps to improve the stability of the threaded rod 202. The telescopic sleeve 204 is provided to improve the stability of the movement of the arc-shaped clamp 208. Rotating the threaded rod 202 facilitates the movement of the threaded rod 202 along the outer shell 201, which adjusts the height of the height adjustment mechanism 2, making it easier to keep the base plate 1 level and prevent uneven ground from affecting the stability of the electrical appliances.

[0041] like Figures 1-3As shown, this invention illustrates a safety-type plastic base for household appliances according to one embodiment of the present invention. The moving mechanism 3 includes a cylinder 301, with a fixed plate 302 fixedly connected to the bottom end of the cylinder 301. Universal wheels 303 are fixedly connected to the four corners of the bottom end of the fixed plate 302. Guide rods 304 are respectively arranged around the cylinder 301. One end of each guide rod 304 is fixedly connected to the base plate 1, and the other end passes through the fixed plate 302 and is fixedly connected to a limit block. The guide rods 304 and the fixed plate 302 are slidably connected. The cylinder 301 is a conventional device known to those skilled in the art and can be selected or customized according to actual needs. In this patent, we only use it without improving its structure and function. Its setting method, installation method, and electrical connection method are not modified. For those skilled in the art, the debugging and operation can be carried out simply by following the instructions in the user manual, and will not be elaborated further here. The cylinder 301 is equipped with a matching control switch. The installation position of the control switch can be selected according to the actual use requirements to facilitate the operation and control by the operator. By driving the cylinder 301, the fixed plate 302 is driven to slide along the guide rod 304, which drives the caster wheel 303 to move closer to or away from the ground. When it is necessary to move the electrical appliance, the cylinder 301 drives the caster wheel 303 to move closer to the ground, so that the height adjustment mechanism 2 is away from the ground, which facilitates the movement of the electrical appliance. After moving to the position that needs to be fixed, the cylinder 301 drives the caster wheel 303 to move in the vertical direction, which drives the caster wheel 303 away from the ground until the height adjustment mechanism 2 is close to the ground to support it, which helps to improve the stability of the base plate 1 and prevent it from moving.

[0042] A second reciprocating screw 6 is rotatably connected to the mounting slot 5. The second reciprocating screw 6 is threadedly connected to the fixing mechanism 4. The fixing mechanism 4 includes a threaded block 401. A rotating block 405 is rotatably connected to the threaded block 401. A gear 406 is fixedly connected to the rotating block 405. The top and bottom ends of the gear 406 are respectively meshed with a first rack 402 and a second rack 407. Rotating the rotating block 405 drives the gear 406 to rotate. The gear 406 rotates and meshes with the first rack 402 and the second rack 407 to move in opposite directions. Rotating the second reciprocating screw 6 drives the two sets of fixing mechanisms 4 to move closer or further apart, which is convenient for adjustment according to the length of the electrical appliance.

[0043] One end of the first rack 402 and the second rack 407 is fixedly connected to the limiting block, and the other end of the first rack 402 and the second rack 407 is fixedly connected to the clamping plate 404. A rubber pad is fixedly connected to one end of the clamping plate 404 near the threaded block 401. A rubber pad is fixedly connected to the threaded block 401. Limiting rods 403 are fixedly connected to both ends of the threaded block 401. The limiting rods 403 are slidably connected to the clamping plate 404. The rubber pad helps to prevent damage to the outer shell of the appliance when the device is fixed to the bottom. The limiting rods 403 help to improve the stability of the movement of the clamping plate 404. The clamping plate 404 can be adjusted according to the width of the appliance, so that the device can fix appliances of various sizes.

[0044] For example, such as Figure 2 As shown, the drive cylinder 301 drives the caster 303 closer to the ground, moving the height adjustment mechanism 2 away from the ground, facilitating the movement of the electrical appliance. After moving to the desired fixed position, the drive cylinder 301 drives the caster 303 to move vertically, moving it away from the ground until the height adjustment mechanism 2 is close to the ground for support, improving the stability of the base plate 1 and preventing it from moving. Rotating the second reciprocating screw 6 moves the two sets of fixing mechanisms 4 closer or further apart, facilitating adjustment according to the length of the electrical appliance. Rotating the rotating block 405 drives the gear 406 to rotate, and the gear 406 meshes with the first rack 402 and the second rack 407, moving them in opposite directions and causing the clamping plate 404 to slide along the limiting rod 403, facilitating adjustment according to the width of the electrical appliance. This allows the device to fix electrical appliances of various sizes.

[0045] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
