Description

Technical Field

[0001] This utility model belongs to the field of mobile phone case technology, and in particular relates to a mobile phone case with an adjustable wristband. Background Technology

[0002] Currently, smartphone use is often inseparable from phone cases, and many types of phone cases have appeared on the market. Most of these phone cases simply serve to enhance the phone's appearance or protect its casing. However, some phone users often hold their phones while resting on public transportation, and due to momentary inattention, the phone may slip from their hand and fall to the ground, sometimes even causing damage. To address this, some phone case manufacturers have incorporated wrist straps into their cases for drop protection.

[0003] For example, Chinese Patent Application No. 202420454503.5 discloses a wristband phone case, including a housing and a wristband, wherein the wristband is disposed on the housing; the housing is provided with a sliding groove; the wristband has a first end and a second end opposite to each other, and the first end and / or the second end is provided with or formed with a sliding member adapted to the sliding groove, the sliding member being embedded in the sliding groove so that the first end and / or the second end can slide relative to the housing; when the first end and the second end are close to each other, a wearing space is formed between the wristband and the housing.

[0004] In the above solution, the position of the wristband on the phone case is restricted by the sliding groove, and the wristband cannot meet the different usage requirements of users. Utility Model Content

[0005] To address the shortcomings of existing technologies, a phone case is provided that allows users to freely change the position of the wristband on the phone case, thereby meeting different user requirements.

[0006] This utility model is achieved using the following technical solution: a mobile phone case with an adjustable wristband, comprising:

[0007] The housing includes a back surface for accommodating a mobile phone and a perimeter surrounding the edge of the back surface, wherein the back surface has a plurality of fastening holes arranged in an array, the fastening holes forming at least two adjustment areas extending in different directions on the back surface;

[0008] A wristband includes a strap body, wherein at least both ends of the strap body are provided with fastening protrusions, the fastening protrusions being freely selectable to fasten with buckle holes at different positions to adjust the position of the wristband on the housing.

[0009] In use, the user can freely select the fastening of the fastening protrusion with the fastening hole in different positions according to needs, so that the wristband has different functions. For example, when the two ends of the wristband are fastened relatively close, the wristband forms an arc-shaped protrusion similar to an arch bridge, and a "Ω" shaped protrusion. At this time, if the wristband is arranged at the middle position of the mobile phone shell, it can be used as a support point of the mobile phone shell, so as to support the mobile phone in an inclined manner. When the user needs to hold the mobile phone, the two ends of the wristband can be fastened relatively far apart, so that the wristband is flat, thereby facilitating the fingers to stretch in. The overall trend of the wristband can be vertical, horizontal, diagonal, etc., and the fastening area is very free, thereby meeting the different use requirements of the user.

[0010] Wherein, how the fastening protrusion is fastened with the fastening hole: 1. The fastening protrusion has elasticity and deforms as a whole to enter the fastening hole and tightly fit with the fastening hole; 2. The fastening hole has elasticity and deforms to make the fastening protrusion enter and tightly fit with the fastening protrusion; 3. The fastening protrusion has a size greater than the fastening end of the fastening hole, and a neck portion with a size comparable to the fastening hole, when the fastening end passes through the fastening hole, the axial position of the fastening protrusion is limited.

[0011] As a preferred, the fastening protrusion comprises a fastening end arranged at the end thereof and a neck portion connecting the fastening end with the band body, the radial size of the fastening end is greater than the hole diameter of the fastening hole, and the radial size of the neck portion is adapted to the hole diameter of the fastening hole;

[0012] The fastening end has elastic deformation ability, and when an axial pressure is applied, the fastening end is radially contracted to be smaller than the hole diameter of the fastening hole, and after passing through the fastening hole, the deformation is restored, so that the fastening end is axially limited by the lower edge of the fastening hole.

[0013] The radial size of the fastening end is greater than the hole diameter of the fastening hole, so that after the fastening end passes through the fastening hole, the fastening protrusion and the fastening hole are axially limited and matched, so that the wristband is not easy to fall off.

[0014] As a preferred, the hole edge of the fastening hole and / or the head circumference of the fastening end is provided with a guide structure, and the guide structure comprises a circumferentially arranged inclined guide surface or an arc-shaped transition surface.

[0015] When the fastening end is inserted into the fastening hole under pressure, the guide structure guides the fastening end to produce radial contraction deformation.

[0016] As a preferred, the back surface is provided with a mesh-shaped reinforcing structure, and the mesh-shaped reinforcing structure comprises:

[0017] A first reinforcing rib group extends along a first direction and is arranged in parallel and uniform spacing;

[0018] A second reinforcing rib group extends along a second direction and is arranged in parallel and uniform spacing;

[0019] The first direction and the second direction have an included angle and are staggered, and the first reinforcing rib group and the second reinforcing rib group jointly form a mesh structure having a plurality of closed grid cells; and the buckle holes are arranged in the closed grid cells.

[0020] Some buckle holes are special in shape, such as rhombus. When the rhombus-shaped buckle holes are arranged in a matrix, the strength of the back surface can be weak, and the back surface can be torn. Therefore, by arranging the reinforcing ribs, the groove frame is formed by the horizontal reinforcing ribs and the vertical reinforcing ribs, and the buckle holes are arranged in the groove frame, so that the strength of the back surface can be increased.

[0021] As a preferred embodiment, the band of the wristband is made of an elastic supporting material. When the distance between the two ends of the buckle is less than the natural length of the band, the band is self-supporting and curved under the compression in the longitudinal or transverse direction, forming a raised supporting structure that can support the mobile phone.

[0022] The band of the wristband is made of an elastic supporting material, which can be rubber material or cowhide material, etc., so that the wristband can be raised to support the mobile phone.

[0023] As a preferred embodiment, the circumferential inner edge of the buckle hole is circular, rectangular, cross-shaped or rhombus-shaped in cross-section.

[0024] As a preferred embodiment, the circumferential outer edge of the buckle is circular, rectangular, cross-shaped or rhombus-shaped in cross-section.

[0025] As a preferred embodiment, the back surface is further provided with an avoidance groove for avoiding the camera.

[0026] Compared with the prior art, the utility model has the advantages that the position of the wristband on the mobile phone shell can be freely changed, thereby meeting different use requirements of users. BRIEF DESCRIPTION OF DRAWINGS

The buckle end head 41 has elastic deformation capability, and when axial pressure is applied, the buckle end head 41 is subjected to radial contraction to be smaller than the hole diameter of the buckle hole 3, and after passing through the buckle hole 3, the deformation is restored, so that the buckle end head 41 is axially limited with the lower edge of the buckle hole 3. In this embodiment 1, the circumferential outer edge of the buckle end head 41 is provided with a guiding structure of the arc-shaped transition surface 6. When the buckle end head 41 is inserted into the buckle hole under pressure, the arc-shaped transition surface 6 guides the buckle end head 41 to produce radial contraction deformation, facilitating the buckle end head 41 to pass through the buckle hole 3.
