Description

Technical Field

[0001] This utility model relates to the field of barcode scanner technology, and in particular to a barcode scanner data cable assembly structure. Background Technology

[0002] As a data acquisition and identification terminal, a barcode scanner can identify detailed information about an item by scanning barcodes or QR codes attached to it. It is widely used in logistics, retail, and warehousing. Wired barcode scanners typically have an external cable at the bottom of the handle. A cylindrical, anti-breakage rubber sleeve is usually installed at the connection point between the external cable and the scanner handle. This sleeve has two circumferentially opposite semi-circular grooves, and multiple sets are arranged side-by-side along the axial direction of the sleeve. Adjacent sets of semi-circular grooves are offset by 90° circumferentially. This design improves the tensile and breakage resistance of the cable end while also providing good flexibility. However, the rubber sleeve is prone to circumferential rotation and axial movement during later use.

[0003] To address the aforementioned technical problems, existing patent 202122023690.0 discloses a barcode scanner data cable assembly structure and a barcode scanner. During data cable assembly, a first fixing block is inserted into the handle through a bone hole, and the data cable is rotated 90°, causing the first fixing block to engage between two locking components. This, combined with a second fixing block located outside the handle on the data cable, restricts the axial and circumferential degrees of freedom of the data cable, improving the connection strength between the data cable and the handle. In the aforementioned prior art, because the first and second fixing blocks are located closer to the handle on the data cable compared to the rubber sleeve, and the only connection between the first and second fixing blocks is the outer rubber sleeve of the data cable, the rubber material of the outer sleeve is prone to breakage due to excessive material fatigue from repeated tightening during later maintenance and repair. Therefore, the number of tightening operations significantly affects its service life. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a data cable assembly structure for a barcode scanner to solve the problem that the number of times it is turned has a significant impact on its service life.

[0005] To achieve the above objectives, this utility model provides a barcode scanner data cable assembly structure, including a collar fixed to the bottom of the handle, wherein the collar and the cable threading hole at the bottom of the handle are coaxial, and the assembly structure further includes:

[0006] Two grooves are provided on the inner wall of the collar, and a limiting part is provided in the groove.

[0007] The limiting part includes a connecting arm fixed in the groove and a latch that is horizontally rotatable on the connecting arm.

[0008] A torsion spring is sleeved on the connecting arm, and the two ends of the torsion spring are respectively fixed on the connecting arm and the buckle.

[0009] The limiting element located between the inside of the latch and the inner wall of the groove triggers the two limiting elements and releases their obstruction of the two latches during the process of the rubber sleeve being inserted into the collar. This causes the free ends of the two latches to deflect towards each other under the torque of the two torsion springs and lock into the two ends of the same semi-circular groove on the rubber sleeve.

[0010] Preferably, the latch is L-shaped in the horizontal direction, and the initial position of the latch is located between the inner wall of the groove and the limiting member. At this time, the free end of the latch is located inside the groove.

[0011] Preferably, the connecting arm includes a horizontal support arm fixed on the arc-shaped inner wall of the groove and a vertical support column fixed to one end of the horizontal support arm.

[0012] Preferably, one end of the latch is rotatably connected to one end of the outside of the vertical support, and the torsion spring is sleeved on the remaining end of the outside of the vertical support.

[0013] Preferably, the limiting member includes an upper support sleeve radially fixed to the inner wall of the groove and a stop bar vertically inserted into the upper support sleeve. The top of the stop bar is radially fixed with an upper retaining bar, and an upper tension spring is sleeved on the top of the outside of the stop bar. The two ends of the upper tension spring are respectively fixed to the bottom of the upper retaining bar and the top of the upper support sleeve.

[0014] Preferably, the upper bar is fixedly disposed on the top of the stop bar along the radial direction of the collar, and one end of the upper bar extends through the inside of the groove into the inside of the collar.

[0015] Preferably, the limiting part further includes a one-way limiting member disposed between the connection between the buckle and the connecting arm and the arc-shaped inner wall of the groove, the one-way limiting member being used to constrain the free end of the buckle to deflect only toward the inside of the collar.

[0016] Preferably, the one-way limiting component includes a ratchet fixed to one end of the latch, the ratchet being rotatably sleeved on the outside of the connecting arm, a lower support sleeve being fixedly provided on the arc-shaped inner wall of the groove along the radial direction of the collar, a slanted insert rod being inserted through one end of the lower support sleeve, the top of the slanted insert rod being an inclined surface, the circumferential orientation of the inclined surface being opposite to the deflection direction of the latch, a pull-down spring being sleeved on the bottom end of the slanted insert rod, the two ends of the pull-down spring being fixedly provided on the outside of the slanted insert rod and on the lower support sleeve, respectively.

[0017] The beneficial effects of this utility model are:

[0018] This invention, during the process of inserting the rubber sleeve at the end of the data cable into the collar, triggers a limiting component and releases its circumferential deflection limit on the latch. This causes the free ends of the two latches to deflect towards each other under the torque of two torsion springs, so that the free ends of the two latches are engaged in the same semi-circular groove on the rubber sleeve. Combined with the one-way limiting component restricting the deflection direction of the latches, the data cable is fixed and assembled. For disassembly, first pull down the two angled plugs to release the circumferential rotation restriction on the ratchet, and then use a flathead screwdriver to pry the latches out of the semi-circular groove to complete the disassembly. This greatly reduces the impact of the number of disassemblies or installations during maintenance on the lifespan of the data cable, improves the fixing firmness of the data cable, and reduces the impact of external forces on the fixing effect of the data cable.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0029] like Figures 1 to 5 As shown, a barcode scanner data cable assembly structure includes a collar 1 fixed to the bottom of the handle. The collar 1 and the cable threading hole at the bottom of the handle are coaxial. The assembly structure also includes:

[0030] Two grooves 2 are provided on the inner wall of the collar 1, and a limiting part 3 is provided in the groove 2.

[0031] The limiting part 3 includes a connecting arm 31 fixed in the groove 2 and a latch 32 that is horizontally rotatably provided on the connecting arm 31.

[0032] A torsion spring 33 is sleeved on the connecting arm 31, and the two ends of the torsion spring 33 are respectively fixed on the connecting arm 31 and the latch 32.

[0033] The limiting members 35, located between the inside of the latch 32 and the inner wall of the groove 2, are triggered during the insertion of the rubber sleeve into the collar 1. This releases the two limiting members 35 from obstructing the two latches 32, causing the free ends of the two latches 32 to deflect towards each other under the torque of the two torsion springs 33, and then snap into place at both ends within the same semi-circular groove on the rubber sleeve. This completes the data cable fixing operation. At this point, the mutual cooperation and limiting between the two latches 32 and the semi-circular groove constrains the circumferential and axial degrees of freedom of the data cable, improving the overall strength of the assembled data cable. In terms of resistance to external forces, during disassembly, simply insert a flathead screwdriver between the latch 32 and the rubber sleeve, then move the latch 32 away from the rubber sleeve and twist the torsion spring 33 to cause elastic deformation and accumulate torque until the free end of the latch 32 separates from the semi-circular groove and completely enters the interior of the groove 2. At this point, the data cable can be removed by pulling it down along the axis of the data cable. This prevents the data cable from being subjected to large external forces during installation or disassembly, avoiding mechanical fatigue damage and extending the service life of the data cable.

[0034] like Figures 2 to 5 As shown, the latch 32 is L-shaped in the horizontal direction, and its initial position is between the arc-shaped inner wall of the groove 2 and the limiting member 35. At this time, the free end of the latch 32 is located inside the groove 2. This design allows the distance between the two latches 32 to be greater than the diameter of the rubber sleeve on the data cable, making it easier to smoothly insert the rubber sleeve on the data cable into the collar 1 axially. This prevents the latch 32 from blocking the rubber sleeve from entering the collar 1 and contacting the limiting member 35, thus smoothly triggering the limiting member 35 and releasing the circumferential deflection restriction of the limiting member 35 on the latch 32. Under the elastic torque of the torsion spring 33, the free end of the latch 32 deflects into the collar 1, thereby bringing the free ends of the two latches 32 closer together and locking into the two ends of the same semi-circular groove on the rubber sleeve. This achieves circumferential and axial constraint of the data cable's degree of freedom, improving the fixing effect and stability of the data cable.

[0035] like Figures 2 to 5 As shown, the connecting arm 31 includes a horizontal support arm fixed on the arc-shaped inner wall of the groove 2 and a vertical support column fixed to one end of the horizontal support arm.

[0036] One end of the latch 32 is rotatably connected to one end of the outside of the vertical support column, and the torsion spring 33 is sleeved on the remaining end of the outside of the vertical support column. This design allows the latch 32 to deflect horizontally under the elastic torque of the torsion spring 33, so that the deflection surface of the latch 32 can be horizontally aligned with the inside of the semi-circular groove on the rubber sleeve, thereby allowing the latch 32 to be accurately fastened into the semi-circular groove.

[0037] like Figures 1 to 5As shown, the limiting member 35 includes an upper support sleeve 351 radially fixed to the arc-shaped inner wall of the groove 2 and a stop bar 352 vertically inserted into the upper support sleeve 351. An upper blocking bar 354 is radially fixed to the top of the stop bar 352, and an upper tension spring 353 is sleeved on the top of the outside of the stop bar 352. The two ends of the upper tension spring 353 are respectively fixed to the bottom of the upper blocking bar 354 and the top of the upper support sleeve 351.

[0038] The upper bar 354 is fixedly mounted on the top of the stop bar 352 along the radial direction of the collar 1, and one end of the upper bar 354 extends through the inside of the groove 2 into the inside of the collar 1.

[0039] like Figures 1 to 5 As shown, the limiting part 3 also includes a one-way limiting member 34 disposed between the connection between the latch 32 and the connecting arm 31 and the arc-shaped inner wall of the groove 2. The one-way limiting member 34 is used to constrain the free end of the latch 32 to deflect only into the collar 1.

[0040] The one-way limiting component 34 includes a ratchet 341 fixed to one end of the latch 32. The ratchet 341 is rotatably sleeved on the outside of the connecting arm 31. A lower support sleeve 342 is fixed on the radial side of the collar 1 on the arc-shaped inner wall of the groove 2. A beveled insert 343 is inserted through one end of the lower support sleeve 342. The top of the beveled insert 343 is an inclined surface, and the orientation of the inclined surface in the circumferential direction is opposite to the deflection direction of the latch 32. A pull-down spring 344 is sleeved on the bottom end of the beveled insert 343. The two ends of the pull-down spring 344 are respectively fixed on the outside of the beveled insert 343 and the lower support sleeve 342. When the data cable is installed, under the one-way limiting effect of the one-way limiting component 34, the latch 32 can only deflect under the elastic torque of the torsion spring 33, and its free end is engaged in one end of the semi-circular groove on the rubber sleeve, and is then connected by two locks. The free ends of the latch 32 are interlocked in the same semi-circular groove to form a circumferential interlocking effect. Combined with the inner wall of the semi-circular groove, the latch 32 is fixed in the axial direction of the data cable, thus restricting the axial and circumferential freedom of the data cable and improving the fixation and stability of the data cable. When disassembling, simply pull down the two angled rods 343 simultaneously to disengage their tops from the teeth of the ratchet 341, so that a flathead screwdriver can be used to pry the free end of the latch 32 out of the semi-circular groove and return it to its initial position. Then, pull out the data cable. When the rubber sleeve is pulled out of the collar 1, the spring force of the upper tension spring 353 causes the stop bar 352 to move down and reset, blocking and fixing the latch 32, so that the free end of the latch 32 is completely located in the groove 2, so that the limiting member 35 can be triggered when reinstalling.

[0041] Working principle: During installation, the rubber sleeve on the data cable is inserted circumferentially into the collar 1 from the outside. The top of the rubber sleeve pushes the upper bar 354 and the stop lever 352 upwards simultaneously until the stop lever 352 separates from the latch 32. This releases the stop lever 352 from obstructing the circumferential deflection of the latch 32. Under the elastic torque of the pre-tensioned torsion spring 33, the free end of the latch 32 deflects inwards towards the collar 1. Thus, the free ends of the two latches 32 approach each other and lock together. The two ends of a semi-circular groove are synchronously inserted into the rubber sleeve, so that the two latches 32 and the semi-circular groove form a circumferential interlocking effect. In conjunction with the semi-circular groove's limiting effect on the latches 32 along the axial direction of the data cable, the axial and circumferential degrees of freedom of the data cable are simultaneously constrained. During this process, under the constraint of the one-way limiting member 34 of the latches 32, only the free end of the latches 32 can deflect inward toward the inside of the collar 1, and when the free end of the latches 32 abuts against the end face inside the semi-circular groove, it is fixed. At this point, the position and state of the latch 32 are sufficient to complete the installation of the data cable, making the installation operation simple and efficient. When disassembling the data cable, simply pull down the two angled plugs 343 simultaneously, causing their tips to disengage from the teeth of the ratchet 341. This allows a flathead screwdriver to be used to pry the free end of the latch 32 out of the semi-circular groove and return it to its initial position. Then, pull out the data cable. When the rubber sleeve is pulled out of the collar 1, the spring force of the upper tension spring 353 causes the stop lever 352 to move down and reset, blocking and fixing the latch 32. This ensures that the free end of the latch 32 is completely located in the groove 2, so that the limiting member 35 can be triggered during reinstallation. In this way, external force is prevented from directly acting on the data cable during disassembly or installation, thereby preventing excessive mechanical fatigue and irreversible damage to the data cable. This improves the service life of the data cable and reduces the impact of the number of times the data cable is disassembled or installed during later maintenance and repair on the service life of the data cable.
