Description

Technical Field

[0001] This utility model relates to the field of voice acquisition equipment technology, and in particular to a portable voice acquisition terminal. Background Technology

[0002] With the increasing demand for mobile work and on-site interviews, voice recording terminals are widely used in scenarios such as news media, meeting minutes, and law enforcement evidence collection. To ensure recording quality, these devices are usually equipped with windproof and dustproof mesh covers, and data cables are essential for data transmission or charging.

[0003] However, existing voice acquisition terminals often neglect portability and ease of maintenance in their structural design. On the one hand, data cables are usually directly connected to the device, lacking an integrated storage structure. During transport, the long data cables are easily tangled and knotted, not only taking up space but also prone to internal breakage or loosening of the connectors due to pulling, affecting their lifespan. On the other hand, dust covers, as easily soiled components, need to be disassembled and cleaned regularly to prevent dust blockage from affecting sound reception. However, existing dust covers are mostly fixed with screws or interference-fit clips, often requiring screwdrivers or other auxiliary tools, or considerable force to pull them out. The operation is cumbersome and laborious, especially when working outdoors, where maintenance becomes difficult without the right tools.

[0004] Therefore, this utility model proposes a portable voice acquisition terminal to address the shortcomings of the prior art. Utility Model Content

[0005] In view of the problems of existing portable voice acquisition terminals, such as the need for tools to disassemble and maintain the dust cover, which is cumbersome to operate, and the lack of an integrated storage structure for the data cable, which makes it inconvenient to carry and prone to tangling, this utility model aims to provide a portable voice acquisition terminal with an improved structure that can effectively solve the above problems.

One end of the data cable is fixed to the main body of the acquisition terminal, and the other end extends into the cable take-up box and is connected to the cable reel. By rotating the cable management knob, the cable reel is rotated to take in the data cable.

[0008] Preferably, in order to achieve tool-free quick disassembly of the dust cover, one end of the limiting pin that engages with the locking hole is provided with a guide arc surface or a guide slope, and a corresponding mating slope is provided at the opening of the locking hole. The guide arc surface or guide slope slides in contact with the mating slope. This structure is used to convert the pulling force into a component force that drives the limiting pin to slide into the spring hole when the dust cover is subjected to a pulling force in the disengagement direction, thereby automatically unlocking.

[0009] Preferably, in order to accurately limit the stroke of the limiting pin, the spring hole is constructed as a stepped blind hole, which includes a small diameter section near the opening and a large diameter section near the bottom. The baffle is slidably fitted in the large diameter section, and the outer diameter of the baffle is larger than the inner diameter of the small diameter section. The side of the baffle away from the telescopic spring abuts against the stepped surface between the small diameter section and the large diameter section.

[0010] Preferably, in order to enhance the shear resistance stability of the take-up box after installation, the iron block protrudes from the top plane of the take-up box, the cross-sectional shape of the iron block is adapted to the cross-sectional shape of the magnetic hole, the iron block is embedded in the magnetic hole and fits against the surface of the magnet to form an embedded positioning fit.

[0011] Preferably, in order to protect the cable and guide the cable in, the side wall of the take-up box is provided with an inlet for the data cable to pass through, and the data cable is wound around the outer periphery of the winding spool after passing through the inlet.

[0015] This utility model has the following beneficial effects: 1. In this utility model, by setting a limiting pin driven by a telescopic spring on the top of the acquisition terminal body, and cooperating with the snap-fit ​​hole and guide slope structure on the dust cover, the problem of cumbersome dust cover fixing method and the need for additional tools for disassembly and maintenance in the prior art is solved. It achieves the technical effect of automatically locking the dust cover by pressing and quickly separating it by pulling without any tools, which greatly improves the convenience of users to disassemble and clean the dust cover.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0020] Example: Please refer to Figures 1 to 4 This utility model provides a portable voice acquisition terminal, which aims to solve the structural defects of the prior art, such as the need for additional tools and cumbersome operation for dust cover disassembly and maintenance, and the lack of storage structure for data cables, which makes them inconvenient to carry and easy to get tangled.

[0021] like Figure 1 , Figure 2 and Figure 3 As shown, the main structure of the portable voice acquisition terminal includes the acquisition terminal body 1, data cable 2, dust cover 3, and cable retractor 4. The dust cover 3 is detachably attached to the top of the acquisition terminal body 1 by means of an elastic buckle mechanism to prevent external dust from entering the device and protect the precision components. The cable retractor 4 is detachably installed at the bottom of the acquisition terminal body 1 by means of magnetic adsorption to wind and store the data cable 2 to improve the overall portability of the device. One end of the data cable 2 is fixedly connected to the side wall of the acquisition terminal body 1, and the other end extends into the inside of the cable retractor 4 and is connected to the internal winding mechanism.

[0022] Specifically, regarding the quick-release connection structure between the data acquisition terminal body 1 and the dust cover 3, a spring hole 6 is vertically inwardly opened on the top surface of the data acquisition terminal body 1. The number of spring holes 6 is preferably two and symmetrically distributed on opposite sides of the top of the data acquisition terminal body 1 to ensure that the dust cover 3 is balanced and fixedly stable. Each spring hole 6 is slidably fitted with a limit pin 5. The limit pin 5 is the main locking component. One end of the limit pin 5 located inside the spring hole 6 is fixedly connected to a baffle 8. The outer circumferential surface of the baffle 8 is tightly fitted with the inner wall of the spring hole 6 and can slide back and forth along the depth direction of the hole. At the same time, a telescopic spring 7 is provided inside the spring hole 6. One end of the telescopic spring 7 abuts against the inner bottom wall of the spring hole 6, and the other end abuts against the surface of the baffle 8. The telescopic spring 7 is always in a compressed or pre-tightened state to provide a continuous outward elastic restoring force. This elastic restoring force drives the limit pin 5 to tend to push outward from the spring hole 6.

[0023] Correspondingly, a snap-fit ​​hole is provided on the side wall of the dust cover 3 at the position of the limiting pin 5. The snap-fit ​​hole is a blind hole or a through hole structure. When the dust cover 3 is installed in place, the end of the limiting pin 5 away from the baffle 8 extends out of the spring hole 6 under the action of the telescopic spring 7 and snaps into the snap-fit ​​hole, thereby realizing a stable snap-fit ​​fixation between the dust cover 3 and the data acquisition terminal body 1. This structure uses the principle of spring-driven pin snap-fit, abandoning the traditional screw fixing method, so that the dust cover 3 can be quickly separated when it needs to be cleaned or replaced.

[0024] For the magnetic connection structure between the acquisition terminal body 1 and the take-up box 4, a magnetic hole 9 is provided at the center or symmetrical position of the bottom of the acquisition terminal body 1. A magnet 10 is fixedly embedded inside the magnetic hole 9 by adhesive bonding or interference fit. The magnet 10 is preferably a neodymium iron boron strong magnet to ensure sufficient adsorption force. An iron block 11 is fixedly provided on the top of the take-up box 4. The iron block 11 is made of stainless steel or industrial pure iron. The position of the iron block 11 corresponds strictly to the position of the magnetic hole 9, and the iron block 11 protrudes from the top plane of the take-up box 4. Its cross-sectional shape is adapted to the cross-sectional shape of the magnetic hole 9. When the take-up box 4 is close to the bottom of the acquisition terminal body 1, the iron block 11 is embedded in the magnetic hole 9 and closely adheres to the surface of the magnet 10. The two are connected by magnetic adsorption, which not only realizes the quick assembly and disassembly of the take-up box 4, but also uses the cooperation between the iron block 11 and the magnetic hole 9 to play a role in positioning and preventing the take-up box 4 from sliding laterally.

[0025] To solve the above-mentioned technical problems, the portable voice acquisition terminal also includes a cable management knob 12 and a cable reel located inside the cable take-up box 4. Furthermore, the cable management knob 12 forms a specific linkage and connection relationship with the aforementioned cable take-up box 4 and data cable 2.

[0026] Please refer to the following carefully. Figure 3 and Figure 4 The cable management knob 12 has a disc-shaped or cylindrical structure that is easy to grip and rotate with fingers, and its outer circumference is preferably provided with anti-slip texture to increase friction. The cable management knob 12 is rotatably connected to the outside of the side wall of the cable take-up box 4. Its rotating shaft passes through the side wall of the cable take-up box 4 and extends into the hollow inner cavity of the cable take-up box 4. The end extending into the inner cavity is fixedly connected to one end of the winding shaft or integrally formed. The winding shaft runs horizontally inside the cable take-up box 4 and can rotate around its own axis. Its function is to provide a support carrier for winding and storing the data cable 2 and to transmit rotational torque.

[0027] Meanwhile, a cable inlet is provided on the side wall of the cable take-up box 4 for the data cable 2 to pass through. The end of the data cable 2 away from the main body 1 passes through the cable inlet and enters the inside of the cable take-up box 4, where it is wound and fixed to the outer circumference of the winding spool. In the assembled state, turning the external cable management knob 12 will drive the internal winding spool to rotate synchronously, thereby orderly winding and storing the long data cable 2 exposed to the outside into the inner cavity of the cable take-up box 4. This structure of external knob driving internal winding spool ensures that the data cable 2 can be completely hidden and stored when not in use, avoiding tangling and knotting of the cable, and greatly improving the cleanliness and portability of the device.

[0028] In addition, to achieve smooth pressing-locking and pulling separation between the dust cover 3 and the limit pin 5, please refer to... Figure 2 The end of the limiting pin 5 inserted into the dust cover 3 is not a flat structure, but is machined with a smooth guide arc surface or guide slope. Correspondingly, the snap-fit ​​hole on the dust cover 3 is also chamfered at the hole opening position with a mating slope that matches the shape of the pin head. When the dust cover 3 is subjected to an upward separation pull, the mating slope presses the guide arc surface or guide slope at the end of the limiting pin 5. Through the principle of slope force component, the vertical pull is converted into a horizontal thrust, driving the limiting pin 5 to overcome the elastic force of the telescopic spring 7 and retract into the spring hole 6, thereby realizing automatic unlocking and separation without tools.

[0029] Based on the above embodiments, the present invention also includes the following preferred technical solutions: As a preferred embodiment, in order to prevent the limiting pin 5 from accidentally dislodging from the spring hole 6 under the elastic force of the telescopic spring 7 and to ensure smooth sliding, the spring hole 6 is machined into a stepped blind hole structure. This stepped blind hole is composed of a small diameter section near the external opening and a large diameter section located deep inside, which are coaxially connected. The outer diameter of the baffle 8 is larger than the inner diameter of the small diameter section but smaller than the inner diameter of the large diameter section, so that the baffle 8 can only slide axially within the large diameter section. When the limiting pin 5 is ejected outward to the limit position, the side end face of the baffle 8 away from the telescopic spring 7 directly abuts against the stepped surface at the junction of the small diameter section and the large diameter section, thereby forming a rigid mechanical limit.

[0030] As another preferred embodiment, in order to enhance the shear resistance of the take-up box 4 after installation and prevent it from sliding laterally relative to the acquisition terminal body 1, the iron block 11 is designed as a protrusion structure protruding from the top plane of the take-up box 4, and the cross-sectional profile of the iron block 11 is adapted to the cross-sectional profile of the magnetic hole 9. When the take-up box 4 is installed in place, the protruding iron block 11 is directly embedded in the magnetic hole 9 until the top surface of the iron block 11 is tightly attracted to the magnet 10 at the bottom of the magnetic hole 9. This embedded fit uses the contact between the hole wall and the side wall of the iron block to limit the horizontal displacement.

[0031] As another preferred embodiment, in order to facilitate the smooth entry of the data cable 2 into the inside of the take-up box 4 without damaging the cable, the side wall edge of the take-up box 4 is provided with an inlet notch for the data cable 2 to pass through. After the data cable 2 is led out from the acquisition terminal body 1, it is directly inserted into the inlet notch and enters the inner cavity of the take-up box 4. The edge of the inlet notch is rounded to prevent wear on the cable sheath. After the data cable 2 enters the inner cavity, it is wound around the outer circumference of the winding spool to ensure a smooth and unobstructed take-up process.

[0032] As another preferred embodiment, in order to further improve the sealing and positioning accuracy of the connection between the dust cover 3 and the data acquisition terminal body 1, the bottom edge of the dust cover 3 extends downward to form a closed or segmented positioning flange. The top edge of the data acquisition terminal body 1 is provided with a positioning groove whose shape and depth match the positioning flange. When the dust cover 3 is closed, the positioning flange is tightly inserted into the positioning groove. This concave-convex fit structure forms a labyrinth-like sealing structure while assisting the limiting pin 5 in fixing, effectively preventing dust from entering.

[0033] As another preferred embodiment, in order to ensure the force balance and stability of the connection structure, the number of limiting pins 5 and spring holes 6 is set to two, and the two spring holes 6 are symmetrically distributed on the left and right sides of the top surface with the central axis of the acquisition terminal body 1 as the reference, to ensure that the dust cover 3 is subjected to uniform force and avoid shaking or tilting caused by single-point fixing.

[0034] As another preferred embodiment, in order to improve the feel and force efficiency of the user when operating the cable management knob 12, the outer circumferential surface of the cable management knob 12 is rolled with anti-slip texture, such as straight lines or mesh patterns, to increase the friction when the fingers pinch it. At the same time, the overall outer contour size of the cable take-up box 4 is designed to be less than or equal to the bottom outer contour size of the acquisition terminal body 1, to ensure that the overall radial volume of the device will not be increased after the cable take-up box 4 is installed, and to maintain the integrity of the appearance.

[0035] Working principle: When the dust cover 3 needs to be installed to protect the top interface of the equipment, the operator presses the dust cover 3 down on the top of the acquisition terminal body 1. The inner wall of the dust cover 3 first contacts and squeezes the guide slope or guide arc surface at the top of the limit pin 5. As the pressing action continues, the vertical pressure is converted into a horizontal thrust through the slope, which overcomes the elasticity of the telescopic spring 7 and forces the limit pin 5 together with the baffle 8 to retract and slide into the spring hole 6 until the dust cover 3 is completely covered. At this time, the snap-fit ​​hole on the side wall of the dust cover 3 is precisely aligned with the position of the limit pin 5. Under the action of the elastic restoring force accumulated by the telescopic spring 7, the limit pin 5 pops out instantly and snaps into the snap-fit ​​hole, completing the automatic locking and fixing of the dust cover 3.

[0036] When it is necessary to remove the dust cover 3 for cleaning or maintenance, simply hold the dust cover 3 and apply a pulling force outward. At this time, the mating inclined surface of the locking hole presses against the guide surface at the end of the limiting pin 5, converting the pulling force along the disengagement direction into a component force that drives the limiting pin 5 to slide inward. This component force then drives the limiting pin 5 to compress the telescopic spring 7 and retract into the spring hole 6, thereby releasing the mechanical lock of the limiting pin 5 on the dust cover 3 and achieving quick disassembly without the need for additional tools such as screwdrivers.

[0037] When you need to take the device out or store long cables, place the cable retractor 4 close to the bottom of the data acquisition terminal body 1. Under the action of the magnetic field, the iron block 11 on the top of the cable retractor 4 will automatically align with and embed into the magnetic hole 9 at the bottom of the data acquisition terminal body 1 until the iron block 11 and the magnet 10 deep in the magnetic hole 9 are tightly attracted, completing the quick assembly and positioning of the cable retractor 4. Then, insert the loose data cable 2 into the cable retractor 4 through the cable inlet. The user pinches and rotates the cable management knob 12 on the side with their fingers. The cable management knob 12 drives the internal winding shaft to rotate synchronously, orderly winding and storing the external data cable 2 in the inner cavity of the cable retractor 4, effectively avoiding the cable from getting tangled and knotted, greatly improving the portability and neatness of the device.

[0038] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
