Description

Technical Field

[0001] This utility model relates to the field of home appliance positioning feet technology, specifically to a home appliance positioning foot. Background Technology

[0002] Home appliances refer to all kinds of electrical and electronic appliances used in homes and similar places. With the diversification of modern family lifestyles, the placement requirements for home appliances are becoming increasingly complex. To meet specific placement needs, it is often necessary to use appliance positioning legs for support.

[0003] However, the legs of existing appliance stands have a relatively simple function, mainly providing support. Their anti-slip properties are generally insufficient, making it difficult to effectively fix the placement of appliances, thus significantly affecting the stability of the appliance placement. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the above-mentioned technical difficulties and provide a positioning foot for home appliances, which can adjust the height of home appliances and can be further attached to the placement surface, greatly improving the stability of placement.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a positioning foot for a household appliance, including a support foot, a support base fixedly connected to the lower end of the support foot, a support sleeve slidably sleeved on the upper end of the support foot, an mounting plate rotatably connected to the upper end of the support sleeve, a movable slot provided on the side wall of the support foot, a positioning piece slidably inserted into the movable slot, multiple positioning holes arranged along the height direction on both outer walls of the support sleeve, a positioning spring cooperating with the positioning piece fixedly connected in the movable slot; a fixing groove provided on the bottom surface of the support base, a positioning suction cup fixedly connected to the lower end of the fixing groove, a control cavity provided on the lower end of the support foot, a connecting hole provided between the fixing groove and the control cavity, a pull bar extending into the control cavity fixedly connected at the upper axis of the positioning suction cup, and a pulling mechanism for driving the pull bar to slide in the control cavity.

[0006] As an improvement, the pulling mechanism includes a strip-shaped lifting hole located on one side of the support foot and communicating with the control cavity. A rotating shaft is rotatably inserted into the strip-shaped lifting hole. A rotating ring is fixedly connected to the upper end of the pull bar. The rotating ring is rotatably sleeved on the outer wall of the rotating shaft. Support cams located on both sides of the pull bar are fixedly connected to the outer wall of the rotating shaft. A knob is fixedly connected to one end of the rotating shaft extending to the strip-shaped lifting hole.

[0007] As an improvement, one end of the positioning piece is provided with a guide groove.

[0008] As an improvement, the upper end of the mounting plate is threaded with at least one mounting bolt.

[0009] As an improvement, a support spring located inside the support sleeve is fixedly connected to the upper end of the support foot.

[0010] The advantages of this utility model compared with the prior art are as follows: the fixed suction cup is adsorbed on the table surface, and the height of the support sleeve for the appliance can be adjusted by the positioning plate and positioning hole. The pulling mechanism is activated to drive the pull bar to slide into the control cavity. The pull bar pulls the suction cup upward to deform, causing the suction cup to stretch and deform, and stably adsorbing the suction cup on the table surface, which greatly improves the stability of the appliance placement.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0018] like Figures 1 to 5As shown, a positioning foot for a household appliance includes a support foot 1. A support base 2 is fixedly connected to the lower end of the support foot 1. A support sleeve 3 is slidably sleeved on the upper end of the support foot 1. A support spring 15 located inside the support sleeve 3 is fixedly connected to the upper end of the support foot 1. A mounting plate 4 is rotatably connected to the upper end of the support sleeve 3. At least one mounting bolt 16 is threadedly connected to the upper end of the mounting plate 4. A movable slot 18 is provided on the side wall of the support foot 1. A positioning piece 5 is slidably inserted into the movable slot 18. A guide groove 17 is provided at one end of the positioning piece 5. Multiple positioning holes 7 are provided on both outer walls of the support sleeve 3 along the height direction. A positioning spring 6 that cooperates with the positioning piece 5 is fixedly connected in the movable slot 18.

[0019] The bottom surface of the support base 2 is provided with a fixing groove 19. A positioning suction cup 20 is fixedly connected to the lower end of the fixing groove 19. The lower end of the support foot 1 is provided with a control cavity 14. A connecting hole is provided between the fixing groove 19 and the control cavity 14. A pull bar 8 extending into the control cavity 14 is fixedly connected to the upper axis of the positioning suction cup 20. A pulling mechanism for driving the pull bar 8 to slide is provided in the control cavity 14. The pulling mechanism includes a strip-shaped lifting hole 13 located on one side of the support foot 1 and communicating with the control cavity 14. A rotating shaft 10 is rotatably inserted into the strip-shaped lifting hole 13. A rotating ring 9 is fixedly connected to the upper end of the pull bar 8. The rotating ring 9 is rotatably sleeved on the outer wall of the rotating shaft 10. Support cams 11 located on both sides of the pull bar 8 are fixedly connected to the outer wall of the rotating shaft 10. A knob 12 is fixedly connected to one end of the rotating shaft 10 extending into the strip-shaped lifting hole 13.

[0020] In practical use, the mounting plate 4 is fixed to the bottom of the appliance using mounting bolts 16. When the height of the appliance needs to be adjusted, the positioning piece 5 is manually pressed to slide into the movable slot 18. The positioning spring 6 is compressed and deformed. At the same time, the guide groove 17 is located inside the support sleeve 3. The support sleeve 3 is rotated to make the positioning hole 7 press against the guide groove 17 of the positioning piece 5, so that the positioning piece 5 is fully inserted into the movable slot 18. The support sleeve 3 is adjusted to slide up and down. After adjusting to a suitable height, the support sleeve 3 is rotated so that the positioning piece 5 is inserted into the positioning hole 7 on one side under the restoring force of the support spring 15, thus realizing the height adjustment and fixation of the appliance.

[0021] Turning the knob 12 drives the rotating shaft 10 to rotate. The rotating shaft 10 drives the support cams 11 at both ends to rotate, so that the support cams 11 abut against the lower end of the control cavity 14, causing the rotating shaft 10 to slide upward along the strip-shaped lifting hole 13. The rotating shaft 10 pulls the pull bar 8 to slide upward along the connecting hole. The pull bar 8 pulls the positioning suction cup 20 to undergo stretching deformation, so that the bottom surface of the fixed suction cup is stably attached to the table surface, which greatly improves the stability of the placement of home appliances.
