Description

Technical Field

[0001] This utility model relates to the field of mobile phone holders, specifically a thin vacuum holder. Background Technology

[0002] A vacuum phone holder, as a type of holder with suction cups, primarily uses the suction cups to attach the holder to a flat surface such as a table, for supporting and using the phone. (See attached instruction manual.) Figure 6 The structure shown, currently the foldable vacuum holder, mainly includes two rotatably connected support frames, a base 1, a rotating disk 3, and a vacuum suction cup 12. The first support frame 4 and the second support frame 5 are connected by a damping pivot shaft, and the bottom of the first support frame 4 is connected to the base 1 by a damping pivot shaft. The two support frames can rotate vertically. The vacuum suction cup 12 is located at the bottom of the base 1, and the rotating disk 3 is installed on the outside of the base 1. The rotating disk 3 has a lifting plate inside, which moves the lifting plate when the rotating disk 3 rotates, thereby contacting the suction force of the vacuum suction cup 12.

[0003] This type of phone holder has the following disadvantages:

[0004] 1. The rotating disk 3 is located on the outside of the base 1, which makes the overall structure relatively high and back. When the two support frames and the base 1 are folded together, the overall height is relatively thick in the folded state.

[0005] Second: The support frame can only rotate vertically and cannot rotate horizontally on the base 1. After the vacuum suction cup 12 is attached to the flat surface where the lamp is placed, the angle between the support frame and the mobile phone cannot be adjusted on the horizontal plane. If you want to adjust the angle between the support frame and the mobile phone, you need to remove the mobile phone holder and reattach it, which is inconvenient. Utility Model Content

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Please see Figure 1-4 As shown, this embodiment discloses a thin vacuum support, comprising:

[0037] The base 1 has a vacuum suction cup 12 at its bottom, which is made of rubber. An annular mounting groove is provided at the edge of the base 1. Figure 4 As shown;

[0038] Rotating ring 2 is set in the mounting groove and is coaxial with the base 1. Rotating ring 2 can rotate in the mounting groove.

[0039] The support frame is rotatably connected to the edge of the rotating ring 2. The support frame can rotate in the vertical direction and is used to place the mobile phone.

[0040] In this embodiment, as Figure 1 As shown, the support frame includes a first support frame 4 and a second support frame 5, as... Figure 1As shown. One edge of the first support frame 4 is rotatably connected to one edge of the second support frame 5, and the bottom of the first support frame 4 is rotatably connected to the edge of the rotating ring 2. All of the above rotatable connections use damped pivot shafts, a common connection technology for mobile phone holders, which will not be elaborated upon here. Both the first support frame 4 and the second support frame 5 are circular ring structures. A magnet 51 is installed inside the second support frame 5, providing magnetic attraction to hold the mobile phone.

[0041] The inner wall of the rotating ring 2 is provided with evenly distributed limiting teeth, such as... Figure 4 As shown, a support column 10 is fixedly installed at the edge of the base 1. A V-shaped support strip 9 is installed on the support column 10. The two ends of the support strip 9 are wound into mounting holes, which fit around the outside of the support column 10, leaving a gap between them. The V-shaped protrusion of the support strip 9 engages with the limiting teeth to limit the rotation ring 2. When the rotation ring 2 rotates, the support strip 9 disengages from the limiting teeth and deforms inward, allowing the rotation ring 2 to rotate. When the rotation ring 2 rotates, it can synchronously rotate the first support frame 4 and the second support frame 5.

[0042] In this embodiment, a rotating seat 3 is also included, which is rotatably mounted on the upper end of the base 1, and its inner sidewall is provided with evenly distributed locking teeth.

[0043] The pressure ring 8 is fixedly installed on the upper surface of the base 1 and located inside the rotating seat 3. The bottom of the pressure ring 8 contacts the upper surface of the rotating ring 2, but is not connected. The pressure ring 8 limits the upper side of the rotating ring 2 to prevent the rotating ring 2 from falling out of the mounting groove. Figure 2 and Figure 4 As shown.

[0044] The cover plate 6 is fixedly connected to the base 1 using bolts. Specifically, as follows... Figure 4 As shown, two upward-protruding connecting protrusions are fixedly installed on the base 1, while the rotating seat 3 has an arc-shaped through groove through which the connecting protrusions extend upward. The cover plate 6 is connected to the connecting protrusions with screws. Due to the arc-shaped through groove, the connecting protrusions do not affect the rotation of the rotating seat 3.

[0045] A slide rail 7 is fixedly installed on the bottom surface of the cover plate 6. A limiting block 13 matching the locking teeth is slidably installed inside the slide rail 7. A spring (not shown in the figure) is installed between one end of the limiting block 13 and the side wall of the slide rail 7. The other end of the limiting block 13 is engaged with the locking teeth. The spring provides an outward elastic force to the limiting block 13 so that the limiting block 13 is engaged with the locking teeth, thereby limiting the rotation seat 3. When not rotated by hand, the rotation seat 3 remains stationary.

[0046] The base 1 also has a lifting seat 11 inside, such as Figure 3 and Figure 4As shown, a mounting opening for installing the lifting seat 11 is provided at the center of the base 1. The mounting opening is rectangular or square. An upwardly extending portion is fixedly installed in the middle of the lifting seat 11, and the extension portion matches the shape of the mounting opening. The lifting seat 11 is coaxially installed with the base 1. A circular connecting plate is fixedly installed at the bottom of the lifting seat 11, and the connecting plate is fixedly connected to the highest part of the vacuum suction cup 12. A helical spring is installed between the upper surface of the connecting plate and the bottom surface of the base 1, and the helical spring provides a downward elastic force to the connecting plate and the base.

[0047] like Figure 5 As shown, a support ring is fixedly installed at the center of the rotating seat 3. The inner wall of the support ring has a sloping structure, specifically as follows: Figure 5 The structure shown has an upper end of the lifting seat 11 extending into the interior of the support ring, and a pin is inserted into the top of the lifting seat 11 (e.g., Figure 2 As shown, the pin is located inside the support ring and on the ramp structure. When the rotating seat 3 rotates, the ramp structure rotates with the rotating seat 3, causing the pin to rise or fall under the action of the ramp structure, thereby raising or lowering the lifting seat 11. In this application, the size of the through groove matches the arc of rotation of the rotating seat 3 or is slightly larger than the arc of rotation of the rotating seat 3, to ensure that the rotating seat 3 has sufficient rotation path for the lifting seat 11 to rise or fall. When the lifting seat 11 rises or falls, it can deform the vacuum suction cup 12, thereby forming a negative pressure vacuum or near-vacuum state between it and the placement surface, generating an adsorption force to adhere to the placement surface.

[0048] In this embodiment, the inner diameter of the first support frame 4 and the second support frame 5 is at least the same as the diameter of the rotating seat 3. The first support frame 4 and the second support frame 5 can rotate downwards and fit over the outside of the rotating seat 3, that is, when the first support frame 4 and the second support frame 5 rotate to a horizontal state (e.g. Figure 2 (As indicated by the folding direction in the middle arrow), the rotating seat 3 is located exactly within the inner ring of the first support frame 4 and the second support frame 5, which reduces the overall height. In the folded state, the overall height is thinner, as shown in the image. Figure 9 As shown.

[0049] When in use, rotate the first support frame 4 and the second support frame 5 outwards to open them, and attach the mobile phone to the second support frame 5. At the same time, press the base 1 downwards. The base 1 exerts downward pressure on the vacuum suction cup 12, thereby deforming the vacuum suction cup 12, squeezing out the air inside, forming a vacuum negative pressure, and thus attaching it to the placement surface.

[0050] When it is necessary to remove it, simply rotate the rotating seat 3, so that the rotating seat 3 moves the lifting seat 11 upward. The lifting seat 11 can then deform upward with the highest point of the vacuum suction cup 12, gradually creating a gap between it and the adsorption surface, and allowing air to enter. When the negative pressure disappears, the adsorption can be released.

[0051] When storing or carrying, simply rotate the first support frame 4 and the second support frame 5 to a horizontal position and place them over the outside of the rotating base 3.

[0052] It should be noted that when releasing the negative pressure adsorption of the suction cup, the lifting seat 11 must be at the bottom (or near the bottom) of the base 1 in order to move upward and cause the vacuum suction cup 12 to deform.

[0053] In a further embodiment, the inner ring of the first support frame 4 is fixedly equipped with a retaining tooth 41, such as... Figure 7 and Figure 8 As shown, the teeth are symmetrically arranged, as... Figure 7 As shown, the locking teeth are located at the part of the first support frame 4 where the rotating shaft is set. When the first support frame 4 rotates downward to a horizontal state, the locking teeth 41 engage with the locking groove 31. When the rotating ring 2 rotates, the first support frame 4 rotates synchronously with the ring 2, thereby causing the rotating seat 3 to rotate.

[0054] It should be noted that, due to the presence of the locking teeth 41 and the locking slots 31, when the first support frame 4 is rotated downwards, the locking teeth 41 may not be aligned with the locking slots 31. It is necessary to manually rotate and align them before the first support frame can be rotated downwards to a horizontal position.

[0055] Alternatively, when making the locking tooth 41, the bottom of the locking tooth 41 is set as a sloping structure. When it rotates downward toward the first support frame 4, the inclined surface of the locking tooth 41 contacts the locking groove 41 and rotates with the locking groove 31, so that the locking tooth 41 and the locking groove 31 are engaged together.

[0056] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
