Description

Technical Field

[0001] The utility model relates to the technical field of barcode scanners, in particular to a connection structure of a barcode scanner wire. Background Art

[0002] At present, the widely used wired barcode scanners on the market are generally equipped with interfaces adapted to standard RJ45 connectors. The connector is connected to the end of the connecting wire, and the interface is used for the connector to be connected to achieve the wired transmission of the barcode scanner data. Such connectors have an anti-detachment structure, effectively ensuring the stability and reliability during connection. However, this anti-detachment structure also has certain limitations. Mainly, when the connector is inserted into the interface of the barcode scanner, it cannot be conveniently disassembled, and special tools are often required to complete the disassembly work, bringing a lot of inconvenience to users. Content of the Utility Model

[0003] The utility model provides a connection structure of a barcode scanner wire to solve the problem of inconvenient disassembly of the connecting wire of the barcode scanner in the prior art.

[0004] The utility model provides a connection structure of a barcode scanner wire, including:

[0005] A barcode scanner handle with an insertion interface provided at the bottom, and the insertion interface is communicated with the inside of the barcode scanner handle;

[0006] A wire with a plug-in part, and the plug-in part is plugged into the insertion interface;

[0007] A clamping mechanism is provided at the bottom of the barcode scanner handle and on one side of the insertion interface, and the clamping mechanism abuts against the plug-in part to prevent the plug-in part from falling off the insertion interface.

[0008] According to a connection structure of a barcode scanner wire provided by the utility model, the plug-in part includes a connector, a connecting member and an extension member. The connector is electrically connected to the wire. The connecting member is sleeved on the wire, the first end of the connecting member is connected to the connector, and the second end of the connecting member is connected to the extension member. The extension member is sleeved on the wire.

[0009] According to a connection structure of a barcode scanner wire provided by the utility model, the cross-sectional dimension of the connecting member is larger than the cross-sectional dimensions of the connector and the extension member.

[0010] According to a connection structure of a barcode scanner wire provided by the utility model, a plurality of waterproof rings are spacedly sleeved on the connecting member. The outer diameter of the waterproof ring is larger than the inner diameter of the insertion interface. The waterproof ring is made of soft rubber material, so that when the connecting member is located in the insertion interface, the outer wall of the waterproof ring extrudes the inner wall of the insertion interface to achieve the waterproof function.

[0011] According to a connection structure of a scanning gun wire provided by the present utility model, the engaging mechanism includes a blocking block and a compression spring. An installation groove is formed at the bottom of the scanning gun handle. The compression spring is located in the installation groove, and the first end of the compression spring is connected to the inner wall of the installation groove. The blocking block is slidably arranged at the bottom of the scanning gun handle. A connecting column is arranged on one side of the blocking block facing the installation groove. The second end of the compression spring is sleeved on the connecting column. Under the action of the compression spring, one end of the blocking block abuts against the extension part to prevent the connecting part from falling off from the insertion interface.

[0012] According to a connection structure of a scanning gun wire provided by the present utility model, a through groove is formed in the middle of the blocking block. A limit screw is arranged at the bottom of the scanning gun handle. The limit screw penetrates through the through groove, and the through groove is slidably connected with the limit screw.

[0013] According to a connection structure of a scanning gun wire provided by the present utility model, a notch adapted to the outer contour of the extension part is formed at one end of the blocking block close to the extension part, and the notch abuts against the outer wall of the extension part.

[0014] For a connection structure of a scanning gun wire provided by the present utility model, by arranging a plugging part on the wire and an engaging mechanism at the bottom of the scanning gun handle, when wiring the scanning gun, the blocking block of the engaging mechanism can be toggled to the side away from the insertion interface, and then the plugging part is plugged into the insertion interface, so that the crystal head is connected to the corresponding interface inside the scanning gun to complete the installation of the data wire. Then, the blocking block is released, and the blocking block abuts against the extension part of the plugging part under the action of the compression spring. At the same time, the blocking block blocks the possibility of the connecting part detaching from the insertion interface, further ensuring the connection stability of the plugging part. When it is necessary to pull out the plugging part from the insertion interface, the blocking block of the engaging mechanism is toggled to the side away from the insertion interface again, and then the plugging part can be pulled out. The cooperation between the plugging part and the engaging mechanism makes the disassembly and assembly of the wire more convenient and fast. In addition, several waterproof rings made of soft rubber materials are sleeved on the connecting part of the plugging part. By the extrusion of the outer wall of the waterproof ring on the inner wall of the insertion interface of the scanning gun, water flow can be prevented from entering the insertion interface.

[0028] To make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions in the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the present utility model. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0029] The following is combined with Figures 1 - 6 Describe a scanning gun wire connection structure of the present utility model, including a scanning gun handle 100, a wire 200 and an engaging mechanism 400.

[0030] A socket 101 is provided at the bottom of the scanning gun handle 100;

[0031] The wire 200 has a plug-in part 300, and the plug-in part 300 is plugged into the socket 101;

[0032] The engaging mechanism 400 is disposed at the bottom of the scanning gun handle 100 and on one side of the insertion port 101. The engaging mechanism 400 abuts against the insertion portion 300 to prevent the insertion portion 300 from falling off the insertion port 101.

[0033] Among them, the insertion portion 300 includes an RJ45 connector 301, a connecting member 302, and an extension member 303. The RJ45 connector 301 is a standard RJ45 connector, which consists of a plastic shell and connecting contacts. The gold plating thickness of the contact three-prong spring is 50μm, meeting the transmission standard of Category 5e. Among the eight pins inside, four are used for sending and receiving data, and the other four may be used for power supply or other transmissions. The RJ45 connector supports a transmission rate of up to 10Gbps and is a key component to achieve electrical continuity between network devices (such as computers, routers, switches, etc.).

[0034] The RJ45 connector 301 is electrically connected to the wire 200. The connecting member 302 is sleeved on the wire 200. The first end of the connecting member 302 is connected to the RJ45 connector 301, and the second end of the connecting member 302 is connected to the extension member 303. The extension member 303 is sleeved on the wire 200.

[0035] Furthermore, the cross-sectional dimension of the connecting member 302 is larger than the cross-sectional dimensions of the RJ45 connector 301 and the extension member 303. A plurality of waterproof rings 304 are spacedly sleeved on the connecting member 302. The outer diameter of the waterproof ring 304 is larger than the inner diameter of the insertion port 101. The waterproof ring 304 is made of soft rubber, so that when the connecting member 302 is located in the insertion port 101, the outer wall of the waterproof ring 304 presses against the inner wall of the insertion port 101 to achieve the waterproof function.

[0036] To prevent current leakage or breakage at the connection between the wire 200 and the insertion portion 300, the material of the extension member 303 is usually selected from heat-resistant, wear-resistant, and corrosion-resistant materials such as PVC (polyvinyl chloride), PE (polyethylene), or TPU (thermoplastic polyurethane rubber) to protect the connection of the wire 200 and extend the service life of the wire 200.

[0037] In this embodiment, as Figure 4 shown, when the insertion portion 300 of the wire 200 is inserted into the insertion port 101 at the bottom of the scanning gun handle 100, the internal structures of the insertion portion 300 and the insertion port 101 are tightly connected, and the blocking block 401 of the engaging mechanism 400 makes the insertion portion 300 inserted into the insertion port 101 under the action of the compression spring 402 and will not fall off easily.

[0038] In terms of specific structure, the crystal head 301 is connected to the corresponding parts inside the scanner handle 100. Since the internal structure of the plug interface 101 does not have an interface that can fix the crystal head 301 in a buckled position, the buckle of the crystal head 301 is naturally straightened, so there is no need for the buckle function of the crystal head 301 to stabilize the connection between the wire 200 and the plug interface 101.

[0039] The locking mechanism 400 includes a blocking block 401 and a compression spring 402. The bottom of the scanner handle 100 is provided with a mounting groove 102. The compression spring 402 is located in the mounting groove 102, and the first end of the compression spring 402 is connected to the inner wall of the mounting groove 102. The blocking block 401 is slidably arranged at the bottom of the scanner handle 100. The blocking block 401 is provided with a connecting column 403 on the side facing the mounting groove 102. The second end of the compression spring 402 is sleeved on the connecting column 403. Under the action of the compression spring 402, one end of the blocking block 401 abuts against the extension member 303 to prevent the connecting member 302 from falling off from the plug interface 101. Among them, the bottom of the scanner handle 100 is provided with two mounting grooves 102, so that the blocking block 401 is stably stressed and slides naturally without jamming.

[0040] In a specific embodiment, when the blocking block 401 is pushed away from the plug port 101, the compression spring 402 gradually overcomes the spring resistance and continuously compresses to increase the elastic force. When the blocking block 401 is released, the blocking block 401 returns to the edge of the plug port 101 under the elastic force of the compression spring 402.

[0041] Furthermore, a through slot 404 is provided in the middle of the blocking block 401, and a limit screw 103 is provided at the bottom of the scanner handle 100. The limit screw 103 passes through the through slot 404, and the through slot 404 is slidably connected to the limit screw 103. The limit screw 103 is used to limit the sliding range of the blocking block 401 to prevent the blocking block 401 from falling off from the mounting slot 102 under the elastic force of the compression spring 402 and the gravity inertia. The limit screw 402 has a guiding function, so that the blocking block 401 slides in a fixed direction, and when sliding along the fixed direction, it is more stable.

[0042] Further, the blocking block 401 is provided with a notch 405 adapted to the outer contour of the extension member 303 at one end close to the extension member 303, and the notch 405 abuts against the outer wall of the extension member 303. A limiting block is arranged outside the insertion interface 101, and its main function is to limit the excessive sliding of the blocking block 401 towards the insertion interface 101 side, so as to prevent the blocking block 401 from excessively squeezing the extension member 303, thereby avoiding adverse effects on the connection between the plugging part 300 and the insertion interface 101. The limiting block is arranged outside the insertion interface 101 to ensure that the notch 405 of the blocking block 401 can abut against the extension member 303 with appropriate force, and at the same time ensure that the blocking block 401 can effectively prevent the connecting member 302 from falling off from the insertion interface 101.

[0043] In this embodiment, as Figures 5 - 6 shown, an insertion interface 101 is provided at the bottom of the scanning gun handle 100, and a latching mechanism 400 is configured on one side of the insertion interface 101. Among them, the notch 405 on one side of the blocking block 401 matches the outer contour of the extension member 303, so as to make a firm abutment, effectively preventing the crystal head 301 from accidentally falling off and ensuring the stability of the connection. When the blocking block 401 is toggled in a direction away from the insertion interface 101, it means that the latching mechanism 400 is in an open state at this time; when the blocking block 401 is released, the blocking block 401 returns to the insertion interface 101 under the action of the compression spring 402, and the notch 405 slightly fits the outer contour of the extension member 303 and abuts against the extension member 303. At this time, it means that the latching mechanism 400 is in a closed state. When the user wants to insert the plugging part 300 of the wire 200 into the insertion interface 101, it is necessary to open the latching mechanism 400, that is, toggle the blocking block 401 in a direction away from the insertion interface 101; when the plugging part 300 is plugged into the insertion interface 101, the latching mechanism 400 is in a closed state at this time, that is, the blocking block 401 abuts against the extension member 303 and the notch 405 fits the outer contour of the extension member 303. The shell material of the insertion interface 101 limits the buckle area of the crystal head 301 to be naturally straightened, so that the original anti-disengagement buckle function is temporarily invalid. However, due to the action of the blocking block 401, the compression spring 402 and the limiting block, the blocking block 401 can prevent the connecting member 302 from falling off from the insertion interface; when the user needs to disassemble the plugging part 300, it is necessary to open the latching mechanism 400 again, that is, slide the blocking block 401 in a direction away from the insertion interface 101, and then the plugging part 300 can be easily pulled out. Subsequently, the blocking block 401 will automatically reset with the help of the compression spring 402, which is convenient and fast, greatly improving the user experience.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
