Description

Technical Field

[0001] The utility model relates to the technical field of mobile phone holders, in particular to a waist-bundling type mobile phone holder. Background Art

[0002] With the rapid development of information technology, smart phones have become increasingly indispensable in modern society. Especially in industries such as logistics and food delivery, smart phones have become the core tools for practitioners in their daily work and life. However, this high dependence has also caused a series of problems, especially in terms of the carrying safety and usage convenience of mobile phones.

[0003] Currently, practitioners in the logistics and food delivery industries usually use smart phones by placing them in their trouser pockets, handbags, car mounts or directly holding them. However, these methods have obvious deficiencies and safety hazards in their working environments where they frequently use mobile phones and need to carry other items at the same time.

[0004] First of all, non-fixed mobile phone storage methods, such as trouser pockets and handbags, are extremely likely to cause the mobile phone to be lost or dropped due to personal negligence or external factors, thus damaging the mobile phone or its screen and affecting its normal use. Secondly, although car mounts can fix the mobile phone, they limit the usage range and flexibility of the mobile phone and are not applicable in non-driving states. Finally, although holding the mobile phone by hand provides high flexibility, when other items need to be operated simultaneously, it is easy to distract attention, reduce work efficiency, and long-term holding of the mobile phone is also likely to cause hand fatigue.

[0005] Although there are some solutions for wearable mobile phone holders in the prior art, most of them are applicable to the field of outdoor live broadcasts and are not applicable to industries such as food delivery and express delivery. For example, in the Chinese utility model patent with the document number CN 215453007U and the name of a portable wearable mobile phone holder for live broadcasts, it does provide the convenience of wearing the mobile phone holder on the body. However, the horizontal telescopic rod and the longitudinally telescopic rod hinged thereto of this patent are locked by a locking knob. This locking method is actually not convenient for opening or closing the longitudinal telescopic rod with one hand. When the user needs to close the longitudinal telescopic rod in time when entering and leaving crowded places, he has to adjust the angle by turning the locking knob, so that the longitudinal telescopic rod is perpendicular to the horizontal telescopic rod, thereby closing the longitudinal telescopic rod. It can be seen that the design of this locking knob is not convenient for one-handed operation and does not really free both hands, so it is not suitable for the food delivery industry.

[0006] Therefore, to solve the above problems, improve the work efficiency of employees in the logistics and food delivery industries, and reduce the risk of mobile phone damage, it is necessary to develop a new type of wearable mobile phone holder device. This device should be easy to wear and allow users to operate with one hand when using it, especially when entering crowded places such as elevators and exhibition halls, and easily adjust the opening and closing of the support arm to ensure that the entire device has good stability and flexibility.

It should be noted that the connecting block can be fixedly connected to the support plate 1, 1a through a fastening bolt 23 or integrally connected with the support plate 1, 1a.

[0043] In some embodiments, as Figure 3 , Figure 5 , Figure 6 shown, the power output device includes: an L - shaped tension spring 5, a first cross - beam 21, a second cross - beam 31 and a hinge part. Among them, the first cross - beam 21 is arranged on the connecting block 2, the second cross - beam 31 is arranged on the support arm 3, and the connecting block 21 and the support arm 3 are hinged through the hinge part; an L - shaped inflection point 51 is provided on the L - shaped tension spring 5. One end of the provided L - shaped inflection point 51 is hooked on the first cross - beam 21, and the other end is hooked on the second cross - beam 31. When needed, the support arm 3 can be hinged relative to the connecting block 2 to a suitable position. The suitable position can be the position where the L - shaped inflection point and the hinge part are coupled. At this time, the L - shaped inflection point and the hinge part act together, so that a fixed angle is formed between the support arm and the connecting block. Specifically, the hinge part is the hinge part as shown in Figure 4 or Figure 9 shown in the figure.

[0044] Among them, the hinge part as shown in Figure 4 shown includes: a first hinge hole 320 provided on the support arm 3, a hinge column 220 provided on the connecting block 2, and an arc - shaped groove 35 located at the first hinge hole 320. The connecting block 2 and the support arm 3 are hinged through the hinge column 220 and the first hinge hole 320. When the support arm 3 is hinged relative to the connecting block 2 to a suitable position, the L - shaped inflection point 51 and the arc - shaped groove 35 act together, so that a fixed angle is formed between the support arm 3 and the connecting block 2.

[0045] As Figure 9 shown, the hinge part includes: a second hinge hole 321 provided on the support arm 3 and a hinge shaft 221 provided on the connecting block 2; the connecting block 2 and the support arm 3 are hinged through the hinge shaft 221 and the second hinge hole 321. When the support arm 3 is hinged relative to the connecting block 2 to a suitable position, the L - shaped inflection point 51 and the hinge shaft 221 act together, so that a fixed angle is formed between the support arm and the connecting block.

[0046] In some embodiments, as Figures 12 - 14As shown, the output device mainly includes the following components: the engaging surface 2a1 of the connecting block, the engaging surface 3a1 of the support arm, the telescopic spring 2a2, the accommodating cavity 2a3, and the screw stopper 2a4. Among them, an accommodating cavity 2a3 is provided on the connecting block 2a. One end of the screw stopper 2a4 is installed inside the accommodating cavity 2a3, and the other end thereof penetrates through the support arm 3a. The telescopic spring 2a2 is also arranged in the accommodating cavity 2a3, and its main function is to ensure that the screw stopper 2a4 can be reset. It should be noted that the number of the telescopic springs 2a2 can be one or two. As Figure 10 shown, the design of using two telescopic springs 2a2 is adopted. In addition, the engaging surface 2a1 of the connecting block and the engaging surface 3a1 of the support arm are respectively arranged on the connecting block 2a and the support arm 3a. After the screw stopper 2a4 is reset, these two engaging surfaces can engage with each other, so that a fixed included angle is formed between the support arm 3a and the connecting block 2a. As Figure 12 shown, the screw stopper 2a4 can be composed of a screw with nuts threadedly connected at both ends.

[0047] As Figure 13 shown, the side surface of the output device is the mounting surface. When in use after installation, the support arm 3a needs to be pulled outward. At this time, the support arm 3a will drive the screw stopper 2a4 to move outward together, resulting in the compression of the telescopic spring 2a2. During the process of pulling the support arm 3a outward, the included angle between the support arm 3a and the connecting block 2a can be adjusted back and forth. After the adjustment is completed, the pulling force on the support arm 3a is released. At this time, the telescopic spring 2a2 will return to its original state and drive the screw stopper 2a4 to reset, thereby making the engaging surface 2a1 of the connecting block and the engaging surface 3a1 of the support arm engage with each other, so as to fix the adjusted included angle. The engaging surface 2a1 of the connecting block and the engaging surface 3a1 of the support arm can be mutually cooperating rack engaging surfaces, or mutually cooperating buckle engaging surfaces, or magnet engaging surfaces.

[0048] In some embodiments, the support plate is the support plate as shown in Figure 10 or the support plate 1a as shown in Figure 11 . In the support plate shown in Figure 11 , the belt hole is composed of the middle groove 111 and the two side edge grooves 112 of the support plate 1, and the middle groove 111 and the edge groove 112 have the same height. In the support plate shown in Figure 10 , the belt hole is the belt gap 1a1 provided on both sides of the support plate. At the same time, Figure 10 and Figure 11 the support plates are both provided with ventilation holes 1a2 / 12. The back surface of the support plate may be provided with an accommodating space, and the back surface is the reverse side of the side of the support plate where the connecting block is provided.

[0049] In some embodiments, the clamping device includes a bolt mobile phone clip 4 or a spring mobile phone clip that realizes the mobile phone clamping function through a spring. As Figure 7 shown, the bolt mobile phone clip 4 includes a main clamping plate 41 and a side clamping plate 42. A first side clamping jaw 431 is arranged on the outer side of the main clamping plate 41, and a second side clamping jaw 432 is arranged on the outer side of the side clamping plate 42. The first side clamping jaw 431 and the second side clamping jaw 432 cooperate with each other to form a clamping space. A positioning column 44 is connected between the main clamping plate 41 and the side clamping plate 42. The adjusting bolt 45 passes through the side clamping plate 42 and is connected to the main clamping plate 41. The adjusting bolt 45 is used to adjust and lock the relative position between the main clamping plate 41 and the side clamping plate 42. Anti-slip textures or rubber pads are arranged on the inner sides of the first side clamping jaw 431 and the second side clamping jaw 432.

[0050] In some embodiments, the waist-style mobile phone holder of the present invention may further include a fastening device, and the fastening device is used to movably connect the clamping device to the support arm. The fastening device may specifically be a square U-shaped buckle or an arc-shaped U-shaped buckle, or other fasteners that can movably connect the clamping device to the support arm. As Figure 8 shown, a bolt hole is provided at the middle position of the square U-shaped buckle 6, and a hand-tightening bolt 61 is arranged thereon. During use, the buckle can be integrally connected or fixed to the back of the clamping device by screws, and the buckle is sleeved on the support arm 3, and then the position of the buckle in the vertical direction of the support arm 3 is adjusted by rotating the hand-tightening bolt 61.

[0051] In some embodiments, a first receiving groove 33 and a second receiving groove 34 are further provided on the support arm. As Figure 3 、 Figure 4 and Figure 9 shown, the first receiving groove 33 is used to receive the L-shaped tension spring, so that the cooperation between the support arm 3 and the connecting block is better. The second receiving groove 34 is mainly used to receive the hand-tightening bolt 61, so that the U-shaped buckle and the clamping device have better stability.

[0052] The dimensions of the waist-style mobile phone holder of the present invention are preferably:

[0053] Name Dimensions (cm) Support Plate Height * Width 16.5 * 13 Connecting Block Length * Width * Height 6 * 3 * 3 Support Arm Length * Width * Thickness 12 * 2.8 * 2.8 Clamping Device Length * Width * Thickness 8 * 8 * 1.5 Middle Groove Width of the middle groove is 5.5, 6 from the upper edge and 5 from the lower edge

[0054] The dimensions of the waist-style mobile phone holder are obtained through the applicant's creative experiments. The size of the upper edge is larger than the size of the lower edge, so that the whole device is more easily fixed by the belt during use. At the same time, the mobile phone holder made according to this size has good practical effects.

[0055] The working process of the present invention:

[0056] As Figure 1When the shown waist-binding mobile phone holder is in use, the support plate 1 can be fixed to the waist by tying the waist-binding belt at the positions of the middle groove 111 and the edge groove 112 of the support plate 1. Since an L-shaped tension spring 5 is connected between the support arm 3 and the connecting block 2, when it is necessary to open the support arm, the support arm 3 can be toggled forward with one hand. At this time, the support arm 3 is hinged forward relative to the connecting block 2. When it moves to a suitable position, the L-shaped inflection point 51 of the L-shaped tension spring 5 is coupled to the hinge axis 221 or the arc-shaped groove 35. At this time, the support arm 3 forms a fixed angle relative to the connecting block 2. This fixed angle is an appropriate visible angle, which is convenient for browsing the mobile phone interface set in the bolt mobile phone clip 4. When it is not necessary to browse the mobile phone interface, the support arm 3 can be toggled back with one hand. When the toggling force is greater than the coupling force between the L-shaped inflection point 51 and the hinge axis 221 or the arc-shaped groove 35, the L-shaped inflection point 51 is separated from the hinge axis 221 or the arc-shaped groove 35. Under the action of the L-shaped tension spring 5, the support arm 3 immediately closes. The closing of the support arm refers to the position of the support arm 3 when it is almost perpendicular to the top surface of the support block. As Figure 2 shown in the closed state of my support arm. When the support arm 3 is closed, the bolt mobile phone clip 4 can be closely attached to the body or the support plate. At this time, when the wearer enters the elevator or a crowded place, this waist-binding mobile phone holder is not likely to collide with the surrounding people and has good flexibility. In addition, the user can adjust the position of the bolt mobile phone clip 4 on the support arm according to his own usage habits and comfort, so as to obtain the best viewing or operating angle.

[0057] It should be noted that when the support arm 3 is opened, the L-shaped inflection point 51 of the L-shaped tension spring 5 may not be coupled to the hinge axis 221 or the arc-shaped groove 35. The applicant has proved through experiments that even if the L-shaped inflection point 51 is not coupled to the hinge axis 221 or the arc-shaped groove 35, the support arm 3 can still form a fixed angle relative to the connecting block 2.

[0058] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
