Description

Technical Field

[0001] This utility model relates to the field of support equipment technology, and in particular to a magnetic lock support foot and an electric fan. Background Technology

[0002] Currently, household appliances often use support frames to facilitate height adjustment, with tripods being the most common. Tripods on the market typically consist of a base and three support legs. The base has three connecting slots on its perimeter, allowing the support legs to rotatably insert into these slots. However, during use, these tripods are prone to the support legs rotating and changing their contact angle with the ground when subjected to external forces.

[0003] Although some mechanical locking devices are provided in the existing technology, these mechanical locking devices are subject to wear and tear during operation, have a short service life, and also generate noise, causing great inconvenience to users. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a magnetic lock support frame.

[0005] A magnetic lock support frame, comprising:

[0006] Support feet;

[0007] A rotating assembly having a rotating shaft whose axis extends horizontally;

[0008] Connecting base; one end of the support leg is placed at an angle on a horizontal surface, and the other end is mounted on the connecting base through the rotating assembly and can rotate around the rotating axis; when the support leg is opened at a certain angle, it is attracted and fixed to the connecting base by a magnetic sheet.

[0009] The magnetic lock support frame described in this utility model limits the support feet by using magnetic plates to attract them, so that the support feet can maintain a stable opening angle. At the same time, the magnetic attraction fixation method is not prone to friction, has a long service life, and avoids noise during use.

[0010] Furthermore, the connecting seat includes a main body and mounting slots; the number of mounting slots corresponds to the number of supporting legs, and includes a top plate and two side plates. One side of the top plate is connected to the main body and is inclined relative to the horizontal plane. The two side plates are connected to both sides of the top plate, and the side plates on the same side are connected between the top plate and the main body, forming a connecting space with the top plate. The supporting legs are installed into the connecting space through a rotating assembly.

[0011] The top plate has a magnet mounting groove, and the magnet piece is disposed in the magnet mounting groove.

[0012] Through the above technical solution, the magnet attracts and fixes the support foot in the connection space, and the top plate and side plates can limit the support foot in three directions.

[0013] Furthermore, a magnet cover is provided on the side of the magnet mounting groove away from the magnet piece.

[0014] Through the above technical solution, the magnetic cover can isolate the magnetic sheet from the external environment, preventing the magnetic sheet from losing magnetism due to the influence of the external environment, thereby reducing its service life.

[0015] Furthermore, the support leg includes a support tube and a rubber foot sleeve; one end of the support tube is connected to the rotating assembly and installed in the connection space, and the rubber foot sleeve is fitted onto the end of the support tube away from the rotating assembly.

[0016] With the above technical solution, a rubber foot sleeve is fitted on the end of the support leg that contacts the ground. This not only enhances stability but also prevents wear on the support leg tube. Furthermore, the rubber foot sleeve is easy to replace.

[0017] Furthermore, the rotating assembly includes a foot tube connector and two rotating shaft sleeves; one end of the foot tube connector is connected to the foot tube, and the other end is provided with a rotating shaft; the two rotating shaft sleeves are fixed in the connecting space and are close to the two side plates respectively; the two ends of the rotating shaft are respectively inserted into the two rotating shaft sleeves.

[0018] Through the above technical solution, the support leg can be rotatably installed into the connection space by the cooperation between the support leg tube and the support leg tube connector, and the support leg tube connector and the rotating shaft sleeve.

[0019] Furthermore, a through hole is provided at one end of the support tube near the support tube connector, and a first threaded hole is provided at the end of the support tube connector that is connected to the support tube. The first threaded hole communicates with the through hole for screw connection and fixation.

[0020] The above technical solution uses screws and through holes and first threaded holes to connect and fix the foot tube and foot tube connector.

[0021] Furthermore, each of the rotating bushings has a second threaded hole on both sides of its radial direction, with the axis extending vertically. The top plate has four connecting posts extending vertically into the connecting space. One end of each connecting post is fixed to the top plate, and the other end has a third threaded hole. The third threaded hole communicates with the second threaded hole for screw connection.

[0022] The above technical solution uses screws and the cooperation of the second and third threaded holes to fix the rotating sleeve in the connection space.

[0023] Furthermore, the support leg is made of iron and its alloys.

[0024] Through the above technical solution, the support foot is made of magnetic metal, which can be fixed by magnetic plates. At the same time, iron and its alloys have a certain mass, which can ensure wind and earthquake resistance.

[0025] An electric fan includes the aforementioned support frame, connecting rod, and fan body, wherein the fan body is mounted on one end of the connecting rod, and the end of the connecting rod away from the fan body is inserted into the connecting seat.

[0026] Furthermore, the connecting seat also includes a locking element; the locking element includes a knob bolt and a locking nut, the knob bolt passing through the connecting seat in a horizontal direction, being threadedly connected to the locking nut and abutting against the connecting rod.

[0038] During its research on existing support frames, the applicant discovered that the reason the support legs easily rotate under external force is that, in existing support frames, the legs are only fixed by friction between the legs and the rotating shaft when open, lacking a limiting device. Based on this, the applicant proposes a support frame with a magnetic plate on the connecting seat, and the support legs are made of a metal that can be attracted by a magnet. When the support legs approach the magnetic plate, the magnetic plate limits their movement, reducing friction and preventing reduced lifespan due to wear. Furthermore, the frame operates without noise, making it convenient for users.

[0039] To better understand and implement this invention, the following detailed description is provided in conjunction with specific embodiments and accompanying drawings.

[0040] Please refer to Figures 1 to 9 , Figure 1 A three-dimensional structural diagram of the magnetic lock support frame provided by this utility model; Figure 2 The front view of the magnetic lock support frame provided by this utility model projected along the vertical direction; Figure 3 for Figure 1 Enlarged section view along the AA direction; Figure 4 A three-dimensional structural diagram of the support foot provided by this utility model; Figure 5 A three-dimensional structural diagram of the connector provided by this utility model; Figure 6 The front view of the connecting seat provided by this utility model projected along the vertical direction; Figure 7 An exploded view of the connecting seat provided by this utility model; Figure 8 A three-dimensional structural diagram of the connecting component provided by this utility model; Figure 9 An exploded view of the connecting component provided by this utility model.

[0041] This utility model provides a magnetic lock support frame, including several support legs 1, connecting seats 2, and a rotating assembly 3. The support legs 1 are placed at an angle on a horizontal surface such as a table or the ground, and their upper ends are rotatably mounted on the connecting seats 2 via the rotating assembly 3. Projected along a direction perpendicular to the horizontal plane, each support leg 1 is evenly distributed along the outer periphery of the connecting seat 2, and the included angle between the center lines of each support leg 1 is equal. In this embodiment, there are three support legs 1, and the included angle between the center lines of each support leg 1 is 120°.

[0042] The support leg 1 includes a support tube 11 and a rubber foot sleeve 12. The support tube 11 is a hollow frame with an opening at the top, and a through hole 111 for inserting screws is provided on the side of the upper end of the support tube 11 near the opening. The support leg 1 is a metal part that can be attracted by a magnet. The rubber foot sleeve 12 is fitted onto the end of the support tube 11 away from the through hole 111. The rubber foot sleeve 12 serves to prevent slippage and shock absorption, allowing the magnetic lock support frame to stand stably. At the same time, the rubber foot sleeve 12 can also prevent wear and scratches caused by direct contact between the bottom of the support tube 11 and the ground or other hard objects, thereby extending the service life of the magnetic lock support frame.

[0043] The connecting seat 2 includes a main body 21, a mounting groove 22, and a locking element 23.

[0044] The main body 21 is a hollow cylinder with its axis perpendicular to the horizontal plane. The mounting grooves 22 are connected to the outer circumferential surface of the main body 21, projected along the axial direction of the main body 21. The mounting grooves 22 are evenly distributed circumferentially around the main body 21, and their number corresponds to the number of support feet 1. Each mounting groove 22 includes a top plate 221 and two side plates 222. The top plate 221 is inclined relative to the axial direction of the main body 21, with one end abutting against the outer circumferential surface of the main body 21 and the other end extending outwards away from the main body 21. The two side plates 222 are connected to opposite sides of the top plate 221, with the side plate 222 on the same side connecting the top plate 221 and the main body 21, forming a connecting space 223 with the side of the top plate 221 facing the main body 21. The overall cross-section is an inverted U-shape. The support feet 1 are installed into the connecting space 223 via the rotating assembly 3, with the left and right sides of the support feet 1 close to the two side plates 222. The top plate 221 and the side plate 222 surround the three sides of the support foot 1, thereby limiting the support foot 1 from three directions.

[0045] In this embodiment, the rotating assembly 3 includes a leg tube connector 31 and two rotating bushings 32. The rotating bushings 32 are fixed within the connecting space 223 and close to the side plates 222, with their axial directions perpendicular to the side plates 222. One end of the leg tube connector 31 is connected to the support leg 11, and the other end is provided with a cylindrical rotating shaft 311, the axial direction of which is parallel to the axial direction of the rotating bushings 32. Both ends of the rotating shaft 311 are respectively inserted into the two rotating bushings 32, and the rotating shaft 311 is capable of rotating relative to the rotating bushings 32.

[0046] Specifically, the foot tube connector 31 has a first threaded hole 312 at one end away from the rotating shaft 311, which is threaded to engage with a screw. The first threaded hole 312 communicates with the through hole 111, so that the screw can install the foot tube connector 31 and the rotating assembly 3 together. The rotating bushing 32 has second threaded holes 321 at both ends in the radial direction for threaded connection with screws. The axis of the second threaded hole 321 extends vertically. The top plate 221 has four connecting posts 224 protruding from it and extending vertically into the connecting space 223. One end of each connecting post 224 is fixed to the top plate 221, and the other end has a third threaded hole 2241, which communicates with the second threaded hole 321.

[0047] During assembly, one end of the leg tube connector 31 with a first threaded hole 312 is inserted into one end of the opening of the leg tube 11. A first screw 41 is inserted into the through hole 111 and threaded into the corresponding first threaded hole 312 to connect the leg tube 11 and the leg tube connector 31. Furthermore, four second screws 42 are respectively inserted into the second threaded hole 321 and the third threaded hole 2241 and threaded to fix the rotating bushing 32 within the connecting space 223. Then, both ends of the rotating shaft 311 are respectively inserted into the rotating bushing 32, thereby allowing the support leg 1 to be rotatably mounted onto the connecting seat 2.

[0048] In other embodiments, the rotating shaft sleeve 32 can be fixed on the support foot 1, and the rotating shaft 311 can be fixed in the connecting space 223. The rotating shaft sleeve 32 is sleeved on both ends of the rotating shaft 311, which also allows the support foot 1 to be rotatably installed on the connecting seat 2, and is not limited to this.

[0049] Furthermore, a magnet mounting groove 2211 is provided on the top plate 221, and a magnet piece 43 is disposed in the magnet mounting groove. The magnet piece 43 is the same size as the magnet mounting groove 2211. Since the support foot 1 is made of magnetic metal, as the support foot 1 opens to approach the top plate 221, it is attracted by the magnet piece 43, thereby maintaining a stable opening angle. Preferably, the cross-section of the support foot 1 is rectangular, and the front side connecting the left and right sides can fit against the top plate 221, thereby giving the magnet piece 43 a better adsorption and fixing effect. Preferably, a magnet cover 2212 is also provided on the magnet mounting groove 2211. The magnet cover 2212 isolates the magnet piece 43 from the outside, preventing the external environment from affecting the magnetic force of the magnet piece 43, thereby improving the service life of the magnet piece 43.

[0050] The connecting seat 2 is connected to the mounting device via the connecting rod 50. Specifically, the main body 21 has a mounting through hole 211, the axis of which is perpendicular to the horizontal plane. The mounting device is installed at one end of the connecting rod 50, and the end of the connecting rod 50 away from the mounting device is inserted into the mounting through hole 211.

[0051] The locking member 23 is used to fix the position of the connecting rod 50. In this embodiment, the locking member 23 includes a knob bolt 231 and a locking nut 232. The knob bolt 231 can pass through the body 21 in a horizontal direction and is threadedly connected to the locking nut 232 before abutting against the connecting rod 50. In use, rotating the knob bolt 231 releases the pressure of the knob bolt 231 on the connecting rod 50, thereby adjusting the installation height of the connecting rod 50. Similarly, when it is necessary to fix the connecting rod 50, the knob bolt 231 is rotated in the opposite direction to make it abut against the connecting rod 50 and fix it.

[0052] Furthermore, in this embodiment, the magnet 43 is mounted on the top plate 221, and the support foot 1 is made of magnetic metal for adsorption and fixation. However, depending on actual needs, the magnet 43 can be mounted on the front side of the support foot 1, and the top plate 221 can also be made of magnetic metal to achieve the same adsorption and fixation effect; it is not limited to this.

[0053] This utility model also provides an electric fan, which includes the tripod support frame, connecting rod 50 and fan body as described above. The fan body is installed at one end of the connecting rod 50, and the end of the connecting rod 50 away from the fan body is inserted into the connecting seat 2.

[0054] This invention provides a magnetic lock support frame and an electric fan. The magnetic lock support frame has a simple structure and is easy to install. It also uses magnets to ensure the stability of the support leg opening angle and has strong anti-interference capabilities. When the electric fan is supported by this magnetic lock support frame, the opening angle of the support legs does not easily change under external force, maintaining a stable working state and ensuring safe and reliable use.

[0055] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and this utility model also intends to include these modifications and variations.
