Description

Technical Field

[0001] The utility model relates to the technical field of washing machine supports, in particular to a supporting frame for a washing machine box. Background Art

[0002] Washing machines are devices that use the principle of converting electrical energy into mechanical energy to wash clothes. In order to meet the growing needs of users, double-drum washing machines have appeared on the market. That is, a washing machine has two independent drums at the same time. Users can choose a suitable drum to wash clothes according to the type, fabric, color, etc. of the clothes, thereby improving the washing efficiency and washing effect of the clothes. Double-drum washing machines are usually stacked, so in order to ensure their stability, a supporting frame of the washing machine body is usually required.

[0003] For example, the patent specification of an existing Chinese patent (publication number: CN216640004U) discloses a support frame of a washing machine and a washing machine, by forming at least one vertical beam and at least one of a plurality of upper beams and a plurality of lower beams into one piece; and / or, forming at least two middle beams into one piece; the stability of the whole machine can be improved, the assembly process can be effectively reduced, the dimensional accuracy of the support frame can be accurately controlled, the number of parts can be reduced, the riveting equipment and labor can be reduced, and the floor space occupied by the riveting equipment can be reduced.

[0004] However, in the implementation of relevant technologies, it was found that the support frame of the washing machine designed above and the washing machine have the following problems: although the support frame of the washing machine can support and place the washing machine, due to the lack of a structure for positioning the washing machine and the support frame is open, the washing machine may fall off the support frame due to the vibration of the washing machine during actual use, which not only poses a major safety hazard, but may also damage the washing machine body and increase unnecessary maintenance costs. In view of this, a support frame for a washing machine body is provided to overcome the above-mentioned defects. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art and proposes a supporting frame for a washing machine case.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a supporting frame for a washing machine case, comprising a supporting frame body, a placement groove is provided on the front side of the supporting frame body, a partition frame is fixedly installed in the middle of the placement groove, a bidirectional screw rod is rotatably provided in the partition frame, two nuts are symmetrically threaded on the bidirectional screw rod, connecting pieces are provided at the top and bottom of the nuts, a positioning piece is provided at the other end of the connecting piece, the positioning piece is slidably connected to the partition frame, a first bevel gear is fixedly sleeved on the bidirectional screw rod, a driving assembly is also provided in the partition frame, and the driving assembly is transmission-connected to the first bevel gear.

[0007] As a further description of the above technical solution: a cavity is arranged in the partition frame, and limit openings are arranged at the top and bottom of the partition frame, the limit openings are communicated with the cavity, the bidirectional screw rod is rotatably connected in the cavity, the connecting piece is slidably inserted in the limit openings, and the drive assembly is arranged in the cavity.

[0008] As a further description of the above technical solution: the driving assembly includes a motor and a second bevel gear, the motor is fixedly installed in the cavity, the second bevel gear is fixedly sleeved on the driving shaft of the motor, and the second bevel gear is meshed and connected with the first bevel gear.

[0009] As a further description of the above technical solution: a base is arranged under the supporting frame, a spacing is left between the base and the supporting frame, a buffer assembly is arranged in the base, and the buffer assembly includes a slide, a buffer column, a buffer spring and a damping cylinder. The slide is slidably arranged in the base, and the two ends of the buffer column are respectively fixedly connected to the top of the slide and the bottom of the supporting frame, and the buffer spring and the damping cylinder are both arranged at the bottom of the slide, and the other ends of the buffer spring and the damping cylinder are connected to the base. When the double-drum washing machine is in use, the washing machine will produce a large vibration. At this time, the supporting frame will move downward, and the buffer column will drive the slide to slide downward and compress the buffer spring. After the vibration is absorbed by the buffer spring, the damping cylinder will finally cooperate to make the buffer spring rebound slowly. This reciprocating process can firstly buffer the vibration of the washing machine, thereby further improving its stability.

[0010] As a further description of the above technical solution: a sliding cavity and a sliding opening are respectively provided inside and on the top of the base, the sliding member is slidably connected in the sliding cavity, the two ends of the buffer spring and the damping cylinder are respectively fixedly connected to the sliding member and the bottom wall of the sliding cavity, and the buffer column is slidably inserted in the sliding opening.

[0011] As a further description of the above technical solution: there are four buffer components, and the four buffer components are respectively arranged at the four corners between the support frame and the base. The four buffer components can not only improve the buffering effect on the washing machine, but also improve the stability of the support frame when it moves vertically up and down.

[0012] As a further description of the above technical solution: guide rods are symmetrically inserted in the slide, and both ends of the guide rods are arranged in the slide cavity, so that the slide can only move along the direction in which the guide rods are set, which can effectively limit the movement direction of the slide and avoid the problem of tilting and offsetting at both ends of the slide.

[0013] As a further description of the above technical solution: the top and bottom of the partition frame are each provided with a plurality of heat conduction ports, and both sides of the support frame are provided with a plurality of heat exhaust ports. The heat conduction ports, the cavity and the heat exhaust ports are interconnected, so that the heat generated by the washing machine can be conveniently discharged to the outside through the heat conduction ports, the cavity and the heat exhaust ports, thereby improving the heat exhaust capacity of the washing machine.

[0014] As a further description of the above technical solution: the support frame and the partition frame are both made of high-carbon steel. Since high-carbon steel has strong strength, the compression resistance of the support frame can be improved.

[0015] The utility model has the following beneficial effects:

[0016] The supporting frame for the washing machine body designed by the utility model can rotate the second bevel gear and drive the first bevel gear and the bidirectional lead screw to rotate by turning on the motor. During this process, the two nuts drive the connecting piece and the positioning piece to approach each other, so that the double-drum washing machine can be clamped stably, and the problem of tipping over and damage caused by vibration generated when the washing machine is running can be avoided, thereby improving safety.

[0017] The support frame for the washing machine body designed by the utility model can cooperate with the sliding piece, the buffer column, the buffer spring and the damping cylinder when the double-drum washing machine is used and generates a large vibration. At this time, the support frame will drive the buffer column and the sliding piece to slide downward and compress the buffer spring. After the vibration is completely absorbed by the buffer spring, the damping cylinder will finally cooperate to make the buffer spring slowly rebound. This reciprocating process can firstly buffer the vibration of the washing machine, thereby further improving its stability. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] A cavity is provided in the partition frame 3, and limit openings 11 are provided at the top and bottom of the partition frame 3. The limit opening 11 is communicated with the cavity, the bidirectional screw rod 4 is rotatably connected in the cavity, the connecting piece 6 is slidably inserted in the limit opening 11, and the driving assembly is provided in the cavity. The driving assembly includes a motor 9 and a second bevel gear 10. The motor 9 is fixedly installed in the cavity, the second bevel gear 10 is fixedly sleeved on the driving shaft of the motor 9, and the second bevel gear 10 is meshed and connected with the first bevel gear 8.

[0026] During the specific implementation, firstly, the double-drum washing machines are placed in the placement groove 2 so that one of them is located at the top of the partition frame 3, and then the motor 9 is turned on to rotate the second bevel gear 10. Since the second bevel gear 10 is meshed and connected with the first bevel gear 8, the rotation of the second bevel gear 10 can drive the first bevel gear 8 and the bidirectional screw 4 to rotate. In this process, the two nuts 5 drive the connecting piece 6 and the positioning piece 7 to approach each other until the double-drum washing machine is clamped stably, which can avoid the problem of tipping over and damage caused by the vibration generated during the operation of the washing machine, thereby improving safety.

[0027] As a further implementation scheme of the above technical scheme: a base 12 is arranged below the support frame 1, and a spacing is left between the base 12 and the support frame 1, and a buffer assembly is arranged in the base 12, and the buffer assembly includes a slide 13, a buffer column 14, a buffer spring 15 and a damping cylinder 16, the slide 13 is slidably arranged in the base 12, and the two ends of the buffer column 14 are respectively fixedly connected to the top of the slide 13 and the bottom of the support frame 1, the buffer spring 15 and the damping cylinder 16 are both arranged at the bottom of the slide 13, and the other ends of the buffer spring 15 and the damping cylinder 16 are connected to the base 12, and a sliding cavity and a sliding mouth are respectively arranged inside and at the top of the base 12, the slide 13 is slidably connected in the sliding cavity, and the two ends of the buffer spring 15 and the damping cylinder 16 are respectively fixedly connected to the slide 13 and the bottom wall of the sliding cavity, and the buffer column 14 is slidably inserted in the sliding mouth.

[0028] In specific implementation, based on the above embodiment, when the double-drum washing machine is in use, the washing machine will generate a large vibration. At this time, the support frame 1 will move downward, and the buffer column 14 will drive the slide 13 to slide downward in the slide cavity and compress the buffer spring 15. After the vibration is completely absorbed by the buffer spring 15, the damping cylinder 16 will finally cooperate to make the buffer spring 15 slowly rebound. This reciprocating process can firstly buffer the vibration of the washing machine, thereby further improving its stability.

[0029] As a further implementation of the above technical solution: there are four buffer components, and the four buffer components are respectively arranged at the four corners between the support frame 1 and the base 12. The four buffer components can not only improve the buffering effect on the washing machine, but also improve the stability of the support frame 1 when it moves vertically up and down.

[0030] As a further implementation of the above technical solution: a guide rod 17 is symmetrically inserted into the slide 13, and both ends of the guide rod 17 are arranged in the slide cavity. The slide 13 can only move along the direction in which the guide rod 17 is set, which can effectively limit the movement direction of the slide 13 and avoid the problem of tilting and offsetting at both ends of the slide 13.

[0031] As a further implementation of the above technical solution: a plurality of heat conduction ports 18 are provided at the top and bottom of the partition frame 3, a plurality of heat dissipation ports 19 are provided at both sides of the support frame 1, and the heat conduction ports 18, the cavity and the heat dissipation ports 19 are connected. The heat generated by the washing machine can be conveniently discharged to the outside through the heat conduction ports 18, the cavity and the heat dissipation ports 19, thereby improving the heat dissipation capacity of the washing machine.

[0032] As a further implementation scheme of the above technical scheme: the support frame body 1 and the partition frame 3 are both made of high carbon steel. Since high carbon steel has strong strength, the compression resistance of the support frame can be improved.

[0033] In addition, in order to facilitate personnel to control the switch of motor 9, we set a controller on the front side of the partition frame 3, and electrically connect the controller to the motor 9, so that personnel operating the controller can send electrical signals to motor 9 and activate its switch, thereby facilitating personnel to control the switch of motor 9.

[0034] As for the controller, by operating the controller, the controller can send an electrical signal to the motor 9 and activate it, thereby achieving the purpose of conveniently controlling the motor 9. Since the controller is a prior art, it will not be described in detail in this manual.

[0035] Working principle:

[0036] When using the utility model, firstly, the double-drum washing machines are placed in the placement groove 2 so that one of them is located at the top of the partition frame 3, and then the motor 9 is turned on to rotate the second bevel gear 10. Since the second bevel gear 10 is meshed and connected with the first bevel gear 8, the rotation of the second bevel gear 10 can drive the first bevel gear 8 and the bidirectional screw rod 4 to rotate. In this process, the two nuts 5 drive the connecting member 6 and the positioning member 7 to approach each other until the double-drum washing machine is clamped stably, and the washing machine can be positioned. When the double-drum washing machine is in use, the washing machine will produce a large vibration. At this time, the supporting frame 1 will move downward, and the buffer column 14 will drive the slide 13 to slide downward in the slide cavity along the direction set by the guide rod 17 and compress the buffer spring 15. After the vibration is completely absorbed by the buffer spring 15, the damping cylinder 16 is finally cooperated to make the buffer spring 15 slowly rebound. This reciprocating process can firstly buffer the vibration of the washing machine, thereby further improving its stability.
