Description

Technical Field

[0001] This utility model relates to a mobile phone holder, specifically a rotatable, angled-top vacuum mobile phone holder. Background Technology

[0002] A phone stand is an auxiliary tool used to stably support a mobile phone. Its main function is to free up the hands, allowing users to use their phones more comfortably and safely in different scenarios.

[0003] Existing phone holders have a complex and poorly designed structure. To attach the phone to a flat surface, the user must forcefully squeeze the suction cups to expel air. Releasing the phone requires considerable manual force to pull the suction cups away from the surface, making the process inconvenient. Furthermore, the phone holder provides no noticeable feedback when rotated, resulting in a poor user experience. Additionally, the screws on existing phone holders are exposed, which is unsightly. Therefore, the inventor has improved the structure of the phone holder. Utility Model Content

[0004] The purpose of this utility model is to provide a rotatable, angled-top vacuum phone holder. This phone holder has a simple structure and reasonable design. By squeezing the two locking blocks, the base can automatically adhere to a smooth surface without the need to squeeze the suction cup. Unlocking can be easily completed by pushing the unlocking block, and there is no need to stretch the suction cup. The adsorption and desorption operations are very simple and convenient, improving the user experience. The rubber ring set on the main cover plate can cover multiple locking screws, making the overall phone holder more aesthetically pleasing. This solves the problems mentioned in the above-mentioned technical background.

The device is placed on a chassis, and the locking blocks can only move unidirectionally on the chassis. Each locking block includes an operating handle and two guide posts fixed to the upper end of the operating handle. The guide posts pass through the binding groove from bottom to top and are set in the binding groove. A first inclined surface is provided at the end of the two operating handles that are close to each other. An inclined top block is located between the two locking blocks, and the two ends of the inclined top block are respectively in contact with the two locking blocks. The inclined top block includes a support frame, and a second inclined surface is formed at both ends of the support frame. The two first inclined surfaces are respectively in contact with the two second inclined surfaces. A positioning screw is provided through the inclined top block from top to bottom. The positioning screw is installed on the base and the inclined top block is fixed to the base by the positioning screw. The base is fixed at the center of the upper end of the chassis, and the base includes a seat body and multiple positioning pins fixed on the seat body. Multiple grooves are formed around the upper end of the seat body, and two adjacent grooves are connected. The suction cup body also includes a limiting spring, and the limiting spring is in contact with the inner wall of the spring limiting groove.

[0006] Preferably, a support arm is fixed to the upper surface of the main cover plate, and a recessed groove is provided on the side of the main cover plate away from the support arm. Multiple locking screws are installed through the recessed groove from top to bottom. All locking screws are installed on the chassis. A rubber ring is provided in the recessed groove to completely cover the multiple locking screws. The cover can be fixed to the chassis by the multiple locking screws. The rubber ring is used to cover the multiple locking screws, making the main cover plate more aesthetically pleasing.

[0007] Preferably, both the limiting strip and the limiting groove are in the shape of a straight line, and there are two of each.

[0008] Preferably, the limiting spring includes a central rod and restraining sleeves symmetrically arranged at both ends of the central rod. The end of the central rod near the arrow body is provided with an arc-shaped outer wall, so that the central rod can better contact the arrow body and allow the unlocking block to move.

[0009] Preferably, both restraint sleeves are C-shaped, and both restraint sleeves have grooves formed on their inner sides. Both grooves have fixing posts on their inner sides, and both fixing posts are fixed to the upper end face of the chassis. The two fixing posts are used to limit the two ends of the limiting spring, so that the central rod can push the arrow body.

[0010] Preferably, it also includes a support component, which includes a support rod and a mobile phone placement component. One end of the support rod is movably connected to the main cover plate via a support arm, and the other end is movably connected to the mobile phone placement component.

[0011] Preferably, the mobile phone placement component includes a support base movably connected to a support rod. A magnet mounting groove is formed on the edge of the support base along its circumferential direction. A pad is provided in the magnet mounting groove. A magnet is laid on top of the pad. A magnet cover is provided above the magnet. The magnet cover covers the magnet mounting groove and completely covers the magnet. The support base is solid or hollow.

[0012] Preferably, two spring mounting slots are symmetrically arranged on the upper end face of the support frame. Each slot contains a return spring, with the end of each spring furthest from the support frame connected to the main cover plate. One end of each spring is connected to the main cover plate, and the other end is connected to a friction ball. The tops of the two friction balls are respectively engaged in the two slots, and the bottoms are respectively positioned in the two grooves. The support frame also has multiple positioning holes, with multiple positioning posts inserted into them. When the user squeezes the two operating handles and brings them closer together, the guide post on each operating handle moves from one corner position in the restraint groove to the center position. At this time, the limit spring automatically pushes the unlocking block to move, causing the unlocking block to move a short distance away from the limit spring, and thus allowing each operating handle to move closer together. The guide pins on the handles move to another corner position within the restraint groove. At this point, the guide pins on the two handles cannot return to their original positions, thus locking the two handles. When the two handles approach each other, they simultaneously press the two ends of the inclined block with the help of the cooperation of the two first inclined surfaces and the two second inclined surfaces. This causes the positioning screw to pull the base upward a short distance, thus lifting the center position of the chassis and allowing the chassis to automatically adhere to a smooth surface, such as a glass surface. Subsequently, when the unlocking block is pressed towards the position of the limit spring, the guide pin on each handle moves from the edge of the restraint groove to the center position of the restraint groove. At this time, the support frame automatically presses the two handles, causing them to return to their original positions. The chassis separates from the smooth surface, completing the unlocking process.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model provides a rotatable angled vacuum mobile phone holder, which includes a suction cup body. The overall structure is simple and reasonably designed. The suction cup body includes a base and a cover on the base. An unlocking block, a locking block, and an angled block are provided between the base and the cover. The unlocking block includes a central body and an arrow body fixed to the central body. An upper positioning block and a lower positioning block are fixed at the end of the arrow body away from the central body. A spring limiting groove is formed between the upper and lower positioning blocks. L-shaped binding grooves are provided at both ends of the central body. Two locking blocks are provided. Each locking block includes an operating handle and two guide posts fixed to the upper end face of the operating handle. The guide posts pass through the binding groove from bottom to top and are set in the binding groove. A first inclined surface is provided at the end of the two operating handles that are close to each other. Located between two locking blocks, with both ends of the inclined top block contacting and connecting to the two locking blocks respectively, the inclined top block includes a support frame, with a second inclined surface formed at both ends of the support frame. The two first inclined surfaces are respectively attached to the two second inclined surfaces. A positioning screw is installed through the inclined top block from top to bottom, and the positioning screw is installed on the base. The suction cup body also includes a limiting spring, which is in contact with the inner wall of the spring limiting groove. When the user squeezes the two operating handles and brings them closer together, the two ends of the inclined top block are simultaneously squeezed by the cooperation of the two first inclined surfaces and the two second inclined surfaces, which causes the positioning screw to pull the base upward a short distance. This lifts the center position of the chassis upward, allowing the chassis to automatically adhere to the smooth surface. This eliminates the trouble of manually pressing the suction cup for adsorption, improves the user experience, and is highly practical.

[0015] 2. The support frame of this utility model has two spring mounting slots symmetrically arranged on its upper end face. Each of the two spring mounting slots is equipped with a return spring. One end of each return spring is connected to the main cover plate, and the other end is connected to a friction ball. The top of each friction ball is respectively engaged in the two slots. The base includes a base body and multiple positioning pins fixed on the base body. The upper end face of the base body forms multiple grooves arranged in a circle. Two adjacent grooves are connected. The bottoms of the two friction balls are respectively set in the two grooves. The support frame is also provided with multiple positioning holes. The multiple positioning pins are respectively inserted into the multiple positioning holes. The return spring is used to squeeze the friction balls so that the friction balls can generate friction with the grooves. When the support assembly is rotated, it drives the structure above the chassis to rotate as well. Therefore, it will drive the two friction balls to rotate continuously in the multiple grooves and generate friction, thereby producing a "clicking" sound, giving the user obvious feedback and achieving the effect of decompression.

[0016] 3. When using this utility model, if unlocking is required, press the unlocking block toward the position of the limiting spring. The guide post on each operating handle moves from the edge of the binding groove to the center of the binding groove. At this time, the support frame will automatically press the two operating handles, causing the two operating handles to return to their original positions. The chassis separates from the smooth surface, and unlocking can be easily completed. The operation of adsorption and desorption of the entire mobile phone holder is very simple and convenient, so it is suitable for widespread use.

[0017] 4. In this utility model, a support arm is fixed to the upper end of the main cover plate, and a recessed groove is provided on the side of the main cover plate away from the support arm. Multiple locking screws are installed through the recessed groove from top to bottom. All locking screws are installed on the chassis. A rubber ring is provided in the recessed groove to completely cover the multiple locking screws. The cover can be fixed to the chassis by the multiple locking screws. The rubber ring is used to cover the multiple locking screws, making the entire mobile phone holder more aesthetically pleasing. Attached Figure Description

[0049] Please refer to it again. Figures 1-12In use, when the user squeezes the two operating handles 141 and brings them closer together, the guide post 142 on each operating handle 141 moves from one corner position in the restraint groove 137 to the center position in the restraint groove 137. At this time, the limiting spring 18 automatically pushes the unlocking block 13 to move, causing the unlocking block 13 to move a short distance away from the limiting spring 18, and causing the guide post 142 on each operating handle 141 to move to the other corner position in the restraint groove 137. At this time, the guide post 142 on the two operating handles 141 cannot return to its original position, so the two operating handles 141 are locked. When the two operating handles 141 are close to each other, they are secured by the two first inclined surfaces 143 and the two second inclined surfaces 144. With the cooperation of 52, both ends of the inclined top block 15 are simultaneously squeezed, and the support frame 151 moves upward a short distance, causing the positioning screw 16 to pull the base 17 upward a short distance as well. This lifts the center position of the chassis 11, allowing the chassis 11 to automatically adhere to a smooth surface, such as a glass surface. Subsequently, when the person presses the unlocking block 13 toward the position of the limit spring 18, the guide post 142 on each operating handle 141 moves from the edge of the restraint groove 137 to the center position of the restraint groove 137. At this time, the support frame 151 will automatically squeeze the two operating handles 141, causing the two operating handles 141 to return to their original positions, and the base 17 to return to its original position, allowing the chassis 11 to separate from the smooth surface, thus completing the unlocking.

[0050] Example 2:

[0051] Please see Figures 13-15 This embodiment is basically the same in structure as Embodiment 1, except that: two spring mounting slots 153 are symmetrically arranged on the upper end face of the support frame 151. Each of the two spring mounting slots 153 contains a return spring 154. One end of each return spring 154 is connected to the main cover plate 121, and the other end is connected to a friction ball 155. The tops of the two friction balls 155 are respectively engaged in two slots 156, and the bottoms of the two friction balls 155 are respectively disposed in two grooves 173. The return springs 154 are used to compress the friction balls 155, allowing the friction balls 155 to generate friction with the grooves 173. The support frame 151 is also provided with multiple positioning holes 157, and multiple positioning posts 172 are respectively inserted into the multiple positioning holes 157. During adsorption, both ends of the support frame 151 are subjected to pressure, causing the support frame 151 to move upward a short distance. The two return springs 154 will be compressed. During unlocking, the two return springs 154 will pop downward a short distance under the action of the main cover plate 121, and generate a downward thrust on the support frame 151, so that the base 17 can return to its original position more smoothly and quickly to complete the unlocking. Other parts not described in this embodiment refer to Embodiment 1, and will not be repeated here.

[0052] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
