Description

Technical Field

[0001] This utility model relates to the field of auxiliary fixing technology for equipment, and in particular to a plastic clamping device and wired controller for electronic devices such as wired controllers and headphones. It is suitable for fixing wired controllers / headphones / controllers to clothing (such as collars and cuffs) to improve ease of use. Background Technology

[0002] In daily life and electronic device usage scenarios, wired remotes, headphones, or small controllers (such as Bluetooth remotes) often swing around freely due to the lack of a fixing device, which can easily cause cables to become tangled or the device to fall off. To solve this problem, existing technologies mostly use a combination structure of "back clip + pin + spring" to achieve fixation. Its working principle is that the spring provides clamping force, and the pin connects the back clip and the clamping arm.

[0003] However, the above-mentioned traditional structure has obvious defects:

[0004] The number of parts is large: it requires three or more parts, such as back clips, pins, and springs, which not only increases the material procurement cost but also increases the complexity of inventory management.

[0005] The assembly process is cumbersome: it requires completing three core steps in sequence: "inserting the pin through the back clamp and clamping arm → spring sleeve on the pin → fixing the end of the pin". Each assembly takes about 30 seconds, resulting in low production efficiency.

[0006] Poor stability: Springs are prone to fatigue failure (such as elasticity decay and breakage) after long-term use, and the pins are prone to loosening due to vibration, resulting in failure of the clamping function and shortening the service life of the equipment.

[0007] Some existing improvement solutions attempt to adopt a simplified structure of "plastic back clip + plastic face cover". Although it has the advantages of fewer parts, simple assembly and stable quality, it does not clearly disclose the specific connection method between the two, the material selection of the elastic component and the structural compatibility. It cannot form a feasible technical solution and is difficult to meet the market's demand for low-cost and high-reliability clamping devices. Utility Model Content

[0008] Therefore, the purpose of this utility model is to provide a plastic clamping device to solve the problems of multiple clamping structure parts, complicated assembly, and easy failure in the prior art.

[0009] Another objective of this invention is to provide a wired control device that includes the above-mentioned clamping device, enabling the wired control device to have convenient and reliable wearing and fixing capabilities.

[0010] To achieve the above objectives, the present invention adopts the following technical solution:

[0011] A plastic clamping device includes a faceplate and a clamping piece; the faceplate is provided with a bearing seat; the clamping piece has an integrally formed pivot at one end, the pivot being rotatably engaged with the bearing seat, allowing the clamping piece to rotate relative to the faceplate; the clamping piece also has an integrally formed elastic portion, which, in its natural state, elastically biases the other end of the clamping piece toward the faceplate, thereby forming a clamping gap between the clamping piece and the faceplate for clamping an item.

[0012] Furthermore, the faceplate has a plurality of first clamping teeth protruding on the side facing the clamping piece in the area corresponding to the clamping gap, and the clamping piece has a plurality of second clamping teeth protruding on the side facing the faceplate in the position corresponding to the first clamping teeth. The first clamping teeth and the second clamping teeth are staggered in a direction perpendicular to the clamping surface, so that when the clamping gap is closed, the tooth tips of the first clamping teeth and the tooth tips of the second clamping teeth intersect each other to enhance the clamping firmness.

[0013] Furthermore, the side of the clamp away from the cover is integrally formed with anti-slip texture to facilitate the user to apply force to open the clamping device.

[0014] Furthermore, the elastic part is made of a high-molecular elastic material such as polypropylene or nylon, and the elastic part and the clip are integrally formed by injection molding, ensuring the overall structural strength and elastic performance.

[0015] Furthermore, the elastic part is designed in an "X" shape, which provides excellent elastic deformation capability and a longer service life within a limited space.

[0016] A wired remote control includes a remote control body and the aforementioned clamping device; the cover is fixedly connected to the remote control body, so that the clamping device and the remote control body form an integrated structure. The fixed connection method includes, but is not limited to, bonding, welding, screw connection, or injection molding.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. Extremely simplified structure and significantly reduced cost: By integrally molding the pivot and elastic part onto the clamping plate and directly snapping it onto the bearing seat of the cover, a clamping device consisting of only two core plastic parts is realized, completely eliminating the traditional pins and independent springs, and greatly reducing material and assembly costs.

[0019] 2. Revolutionary improvement in assembly efficiency: The assembly process is simplified to simply snapping the rotating shaft of the clamp into the bearing seat of the cover. This "one-step" assembly greatly improves production efficiency and is suitable for automated mass production.

[0020] 3. Enhanced reliability and durability: The elastic part is made of polymer materials (such as PP and nylon), which avoids the fatigue and corrosion problems of metal springs and has a longer service life; the overall plastic structure has no risk of loosening and the clamping force is stable.

[0021] 4. Enhanced user experience: The overall structure is lightweight and thin, with no hard metal parts, making it comfortable to wear; the anti-slip texture and staggered clamping teeth design make operation convenient and the grip secure. Attached Figure Description

[0030] The accompanying drawings have illustrated specific embodiments of the present invention, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the present invention in any way, but rather to illustrate the concept of the present invention to those skilled in the art through reference to specific embodiments. Detailed Implementation

[0031] 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, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0032] To make the technical solution and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0033] Please see Figures 1-5 As shown, the plastic clamping device provided by this utility model mainly consists of two parts: a faceplate 1 and a clamping piece 2. Both can be molded by injection molding, and engineering plastics such as polypropylene (PP), nylon (PA), or ABS are preferred.

[0034] like Figure 2 and Figure 3 As shown, the cover 1 is generally a plate-like structure, with at least one bearing seat 12 on one side. In this embodiment, the bearing seat 12 consists of two opposing vertical walls, each with a circular hole or a U-shaped latch. The clamping piece 2 is a long strip-shaped plate with a rotating shaft 22 integrally formed at one end by injection molding. The rotating shaft 22 is preferably cylindrical, and its diameter matches the circular hole or U-shaped latch on the bearing seat 12. During assembly, the rotating shaft 22 is pressed or latched between the two bearing seats 12 by slight elastic deformation, forming a rotating connection. This "clamping" method requires no additional connecting parts, achieving extremely simple assembly.

[0035] The core innovation lies in the fact that the clamping piece 2, near the pivot 22, has an integrally molded elastic portion 24. In its natural state (i.e., without external force), the internal stress of this elastic portion 24 forces the other end (the free end) of the clamping piece 2 to continuously bias towards the cover 1. This continuous biasing force creates a clamping gap with a constant clamping force between the free end of the clamping piece 2 and the cover 1. When it is necessary to clamp an item (such as clothing), the user simply pulls the free end of the clamping piece 2 outwards, places the item into the gap, and releases it; the rebound force of the elastic portion 24 firmly clamps it in place.

[0036] In a preferred embodiment, as shown in the accompanying drawings, the elastic portion 24 is designed in an "X" shape. This structure, like a miniature plastic spring, provides a uniform and smooth elastic force when the clip 2 opens and closes, and the stress distribution is more reasonable, resulting in significantly better fatigue resistance than a simple sheet cantilever beam structure.

[0037] To enhance the clamping effect, multiple parallel first clamping teeth 11 are protruding on the side of the cover 1 facing the clamping piece 2, corresponding to the area of ​​the clamping gap. Correspondingly, multiple parallel second clamping teeth 21 are also protruding on the side of the clamping piece 2 facing the cover 1. These first clamping teeth 11 and second clamping teeth 21 are staggered in position. When the clamping gap is closed, the tips of the first clamping teeth 11 and the tips of the second clamping teeth 21 interlock, like the teeth of two combs interlocking. This "interlocking" structure effectively prevents the clamped clothing from slipping off, greatly enhancing the reliability of the clamping.

[0038] In addition, such as Figure 2 As shown, anti-slip texture 23 is integrally formed on the outer surface of the clip 2 away from the cover 1. These textures can be wavy, dotted, or striped, and their function is to increase the friction between the user's fingers and the clip 2, so that the user can apply force more easily and stably to open the clamping device.

[0039] This utility model also protects a wired controller that integrates the above-mentioned clamping device. For example... Figure 5 As shown, the wired remote control includes a wired remote control body 3 and the aforementioned clamping device. The back side of the cover 1 (i.e., the side away from the clamping piece 2) is fixed to the housing of the wired remote control body 3 by means of adhesive, ultrasonic welding, screws, or integral molding during the injection molding of the wired remote control housing. Thus, the clamping device and the wired remote control body 3 form a compact and functionally integrated whole, allowing users to easily clip it to a collar, pocket edge, or backpack strap, etc.

[0040] In summary, this utility model, through its ingenious integrated structural design, achieves a stable and reliable clamping function with the fewest possible parts, bringing significant improvements in cost, efficiency, and reliability.
