Description

Technical Field

[0001] This utility model belongs to the field of RFID technology, specifically relating to a lightweight RFID reader / writer on a desktop. Background Technology

[0002] In existing small and medium-sized work scenarios, such as offices, reception desks, and small warehouse receiving and dispatching stations, the verification of single or small quantities of items with RFID tags usually relies on operators holding lightweight RFID readers. During use, operators need to constantly move around the object to be tested and adjust the angle of their hands to find the best signal reading position. This process is particularly cumbersome for objects that need to read tags from multiple directions, which not only increases the labor intensity of operators but also leads to low overall reading efficiency. Moreover, the handheld operation method depends entirely on the stability of the operator's grip. In actual work, due to factors such as operational negligence, fatigue, or accidental external collisions, the RFID reader is very likely to slip from the hand, causing irreversible physical damage such as broken casing and damage to internal electronic components. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a lightweight RFID reader / writer on a desktop, comprising a desktop and table legs. The table legs are symmetrically arranged on the bottom left and right sides of the desktop. Fixing frames are provided on the top left and right sides of the desktop. An inner plate is connected between the bottom of the fixing frames. A sliding groove is formed between the inner plate and the desktop. A connecting rod is slidably arranged in the sliding groove. A push plate is provided on the top of the connecting rod. An RFID reader / writer is installed on the top of the push plate. A first slide rail is fixedly connected between the upper parts of the table legs. An extension rod is connected to the bottom of each table leg. A second slide rail is connected between the tops of the extension rods. A main roller is connected to the upper part of the connecting rod. Two auxiliary rollers are rotatably connected to the middle of the connecting rod through a clamping plate.

[0005] Preferably, the main roller is slidably embedded inside the first slide rail, and the auxiliary roller is slidably embedded inside the second slide rail.

[0006] Preferably, both the first and second slide rails are racetrack-shaped cylinders.

[0007] Preferably, the connecting rod is hollow.

[0008] Preferably, the RFID reader is connected to a power cord at its bottom, and the power cord is pulled downwards via the connecting rod.

Detailed Implementation

[0021] 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, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] like Figures 1 to 4 The illustrated lightweight RFID reader / writer on a desktop includes a desktop 1 and table legs 2. The table legs 2 are symmetrically arranged on the bottom left and right sides of the desktop 1. Fixing frames 6 are located on the top left and right sides of the desktop 1. An inner plate 7 is connected between the bottom of the fixing frames 6, forming a sliding groove 8 between the inner plate 7 and the desktop 1. A connecting rod 9 slides within the sliding groove 8. A push plate 10 is located at the top of the connecting rod 9, and an RFID reader / writer 15 is mounted on the top of the push plate 10. A first slide rail 3 is fixedly connected between the upper parts of the table legs 2. Extension rods 4 are connected to the bottom inner sides of each table leg 2, and a second slide rail 5 is connected between the tops of the extension rods 4. The upper part of the connecting rod 9 is connected to the main roller 12, which is located below the desktop plate 1; the middle part of the connecting rod 9 is rotatably connected to two auxiliary rollers 14 through a clamping plate 13; the main roller 12 is slidably embedded in the inner side of the first slide rail 3, and the auxiliary rollers 14 are slidably embedded in the inner side of the second slide rail 5; the first slide rail 3 and the second slide rail 5 are both racetrack-shaped cylinders; the connecting rod 9 is hollow; the bottom of the RFID reader 15 is connected to a power cord 16, which is pulled out downward through the connecting rod 9; a stop block 17 is provided in the slide groove 8; auxiliary grooves 18 are provided on both the left and right sides of the push plate 10; and ball bearings 11 are provided at the bottom of the push plate 10.

[0024] This invention features a reader / writer structure that slides within an annular groove 8. Operators do not need to hold the device or walk around objects; they can simply push the push plate 10 to make the RFID reader / writer 15 scan around the object in the center of the table, reducing labor costs while enabling multi-directional tag reading and effectively improving detection efficiency. The reader / writer is securely restrained within the groove 8 by the push plate 10 and connecting rod 9, and connected to a stable support system consisting of a main roller 12, a secondary roller 14, and double slide rails. This avoids the risk of the device falling due to hand instability, fatigue, or accidental collisions, protecting the reader / writer from physical damage and extending its lifespan. Furthermore, the hollow connecting rod 9 design houses the power cord 16, which extends from its bottom, making the power cord 16 more organized as the device moves. The stop block 17 within the groove 8 effectively limits the reader's rotational stroke, preventing the power cord 16 from tangling, knotting, or being excessively pulled during repeated rotation.

[0025] Example 2

[0026] like Figures 1 to 4 The illustrated RFID reader / writer is a lightweight desktop unit. Its structure mainly includes a desktop panel 1 and symmetrically arranged table legs 2 at its bottom. Fixtures 6 are mounted on the top left and right sides of the desktop panel 1, and an inner plate 7 is horizontally connected between the bottoms of the two fixtures 6. A groove 8 is formed between the inner plate 7 and the upper surface of the desktop panel 1. The groove 8 is designed as a closed loop structure similar to an athletic track, with a connecting rod 9 sliding inside. The top of the connecting rod 9 is fixedly connected to a push plate 10. The push plate 10 limits the movement of the connecting rod 9, allowing it to slide smoothly within the groove 8. Multiple ball bearings 11 are embedded in the bottom of the push plate 10, enabling it to achieve low-resistance, flexible reciprocating motion within the groove 8 through the coordinated action of the ball bearings 11 and the connecting rod 9. After the RFID reader 15 is installed on the top of the push plate 10, the user can place the object to be detected on the table and then push the push plate 10 to make the reader move around the object along the slide 8, thereby realizing flexible scanning and identification of the object in different positions.

[0027] Furthermore, auxiliary grooves 18 are provided on both the left and right sides of the push plate 10. The auxiliary grooves 18 match the shape of human fingers and the curvature of human fingers, so that users can get a comfortable and stable force application feeling whether they push the push plate 10 from the left or the right, thus making it easier to control the movement of the reader.

[0028] To maintain the flexibility of the connecting rod 9 while enhancing its stability during operation, the device has been further optimized in structure: a first slide rail 3 is fixedly connected between the upper parts of the two table legs 2, and height-adjustable extension rods 4 are installed on the inner bottom of the table legs 2. A second slide rail 5 is horizontally connected between the tops of these extension rods 4. A main roller 12 is mounted on the upper part of the connecting rod 9, located below the tabletop 1 and sliding within the inner side of the first slide rail 3. Two auxiliary rollers 14 are rotatably connected to the middle of the connecting rod 9 via a set of clamps 13, and these auxiliary rollers 14 slide along the outer side of the second slide rail 5. Both the first slide rail 3 and the second slide rail 5 adopt a racetrack-shaped cylindrical structure. This design of double slide rails and rollers significantly improves the guidance and overall stability of the connecting rod 9 during movement, effectively preventing swaying and deviation.

[0029] The bottom of the RFID reader 15 is connected to a power cord 16. For ease of wiring and movement, the connecting rod 9 has a hollow design, allowing the power cord 16 to pass through and extend downwards to connect to an external power source, thus powering the reader. To prevent the power cord 16 from becoming tangled or knotted due to continuous rotation of the reader within the slide 8, a stop block 17 is installed inside the slide 8. This stop block 17 limits the movement range of the push plate 10 and the reader, ensuring that their travel within the slide 8 does not exceed one revolution. This fundamentally eliminates the problem of the power cord 16 becoming tangled due to excessive rotation, ensuring the long-term reliability and safety of the equipment.
