Description

Technical Field

[0001] This utility model relates to the field of barcode scanner technology, and in particular to an anti-slip barcode scanner. Background Technology

[0002] Currently, barcode scanners, used in conjunction with barcodes or QR codes, can quickly and accurately read and save detailed information about items compared to manual data entry. Therefore, barcode scanners are widely used in logistics, warehousing, and retail. When in use, a barcode scanner is typically placed sideways on a table for easy access. However, due to the height difference between the grip and the scanner head, the contact area between the scanner and the table is small, resulting in poor anti-slip properties and making it easy for the scanner to slip off the table even with minor external forces.

[0003] To address the aforementioned technical problems, prior art patent application number 202420221546.9 discloses an anti-slip barcode scanner. This device, through the coordinated use of a support unit, raised strips, support rubber strips, and a support plate, makes the scanner more stable. Simultaneously, the anti-slip strips provide an anti-slip effect, preventing the scanner body from easily moving. However, in the aforementioned prior art, this device is only suitable for wireless scanners. For scanners with external cables on the handle, during use, if the external cable is pulled by external force, the scanner will still slip off the table. Its horizontal stability on the table is relatively low, making it prone to slipping due to external forces. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose an anti-slip barcode scanner to solve the problem that the horizontal stability of the scanner is relatively low when placed on a table and it is easy to slip off due to external force.

[0005] To achieve the above objectives, this utility model provides an anti-slip barcode scanner, including a support base and a groove on the top of the support base. The anti-slip barcode scanner further includes:

[0006] Two connectors located on the barcode scanner handle and two limiting parts located in the groove cooperate to fix the barcode scanner horizontally on the table.

[0007] The connector includes a support post fixed to the barcode scanner grip and a wedge-shaped strip fixed to the end face of the support post.

[0008] The limiting part includes two limiting strips that are slidably disposed in the groove and a strip groove disposed on the opposite surface of the two limiting strips. A linkage is provided between the bottoms of the two limiting strips. The linkage is used to make the two limiting strips move closer to each other or further away when the wedge strip is inserted between the two strip grooves or pulled out from between them.

[0009] Preferably, the shapes of the opposite surfaces of the strip groove and the wedge strip are matched, and the two strip grooves together form a limiting groove, wherein the vertical cross section inside the limiting groove matches the vertical cross section of the wedge strip.

[0010] Preferably, the limiting part further includes two baffles fixed relative to each other in the groove, the baffles being opposite to the end face of the limiting strip, and the limiting strip being located between the two baffles.

[0011] Preferably, the linkage includes two guide strips fixedly fixed in the groove and a rack fixed to the bottom of the limiting strip. One side of the guide strip is slidably connected to the guide groove provided on the rack. The two racks are located between the two guide strips and correspond one-to-one with the guide strips. A gear is rotatably provided in the groove. The two sides of the gear tooth surface mesh with the tooth surfaces of the two racks respectively. An elastic telescopic rod is provided between the end face of one of the racks and the bottom of the groove. The elastic telescopic rod is used to bring the two adjacent limiting strips closer together and reset when the wedge strip is inserted between or pulled out from between the two adjacent limiting strips.

[0012] Preferably, the rack is located between the guide bar and the gear, and the two limiting bars are located on the ends of the two racks on different sides of the top.

[0013] Preferably, the top of the opposite surfaces of two adjacent limiting strips are both inclined surfaces, and the inclined surfaces are located between the boundary of the top of the strip groove and the top of the limiting strip.

[0014] Preferably, the angle between the inclined surface and the vertical surface is greater than 0° and less than 45°, the two inclined surfaces are in an inverted V-shape, and the minimum distance between the two inclined surfaces is greater than the width of the bottom of the wedge strip.

[0015] Preferably, the guide strips are parallel to the baffles, and the two guide strips are located between the two baffles.

[0016] The beneficial effects of this utility model are:

[0017] This invention utilizes the locking and limiting effect between two sets of connectors and limiting parts. Through a flat placement action, the wedge-shaped strip is inserted between the opposing slots on two adjacent limiting strips. The interlocking of the wedge-shaped strip and the opposing slots, along with the limiting and blocking effect of two opposing baffles on both ends of the slots, restricts the scanner's horizontal freedom. This prevents the scanner from slipping off the table due to significant horizontal displacement caused by external force pulling the tail wire, allowing the scanner to be picked up only vertically. This improves the stability and firmness of the scanner on the table. Furthermore, the linkage mechanism allows the scanner's own weight to push the two limiting strips apart when lowering it, ensuring the wedge-shaped strip is stably inserted between them. Picking it up requires only overcoming a small amount of friction and the spring force of the return spring, making the picking and putting-down actions ergonomic and improving the user experience.

[0026] 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.

[0028] like Figures 1 to 5 As shown, an anti-slip barcode scanner includes a support base 1 and a groove 3 on the top of the support base 1. The bottom of the support base 1 is detachably mounted on a table. The anti-slip barcode scanner also includes:

[0029] The two connectors 2 located on the barcode scanner handle and the two limiting parts 4 located in the groove 3 cooperate with each other to fix the barcode scanner horizontally on the table.

[0030] The connector 2 includes a support post 21 fixed to the bar grip of the scanner and a wedge strip 22 fixed to the end face of the support post 21. Both sides of the wedge strip 22 are protrusions. The vertical cross-section of the protrusion is an isosceles trapezoid, and the width of the vertical surface of the protrusion away from the support post 21 is smaller than the width of the connection surface between the protrusion and the support post 21.

[0031] The limiting part 4 includes two limiting strips 41 that are slidably disposed in the groove 3 and strip grooves 42 disposed on the opposing surfaces of the two limiting strips 41. A linkage 43 is provided between the bottoms of the two limiting strips 41. The linkage 43 is used to move the two limiting strips 41 closer to each other or further away when the wedge strip is inserted between or pulled out from between the two strip grooves 42. When the scanner is lowered, after the wedge strip 22 is aligned with the two adjacent limiting strips 41, the scanner can be lowered. Under the action of the scanner's gravity, the inclined surface on the wedge strip 22 abuts against the two opposing boundaries of the top of the two limiting strips 41. When the wedge strip 22 falls between the two, the linkage 43 pushes the two limiting strips 41 together. The positioning bars 41 move away from each other until the wedge-shaped bar 22 falls completely between the two positioning bars 41. Then, under the linkage reset of the linkage member 43, the two positioning bars 41 move closer to each other and reset, thus clamping the wedge-shaped bar 22. The distance between one of the positioning bars 41 and one of the inner walls of the groove 3 in its moving direction is equal to the moving distance of the positioning bar 41, so as to limit the amount of movement of the positioning bar 41 and avoid excessive displacement, which would affect the horizontal positioning effect between the connector 2 and the positioning part 4. In this way, the bar can be prevented from being pulled off the table when the tail wire on the bar grip is pulled by external force, thus improving the stability of the bar when it is placed on the table and effectively preventing the bar from slipping.

[0032] like Figures 1 to 5 As shown, the shapes of the opposite surfaces of the strip groove 42 and the wedge strip 22 are matched, and the two strip grooves 42 together form a limiting groove. The vertical section inside the limiting groove matches the vertical section of the wedge strip 22. With this design, when the tail wire on the barcode scanner handle is pulled by an external force, the convex surface on the wedge strip 22 abuts against the strip groove 42, so that the two form a horizontal interlocking effect, which effectively restrains the freedom of the barcode scanner in the horizontal direction, prevents it from slipping off the table under the pull of an external force, and protects it from being damaged by falling.

[0033] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the limiting part 4 also includes two baffles 44 that are fixed relative to each other in the groove 3. The baffles 44 are opposite to the end face of the limiting strip 41, and the limiting strip 41 is located between the two baffles 44.

[0034] The linkage 43 includes two guide bars 434 fixedly within the groove 3 and a rack 431 fixed to the bottom of the limiting bar 41. One side of each guide bar 434 is slidably connected to a guide groove 433 on the rack 431. The two racks 431 are located between the two guide bars 434 and correspond one-to-one with each guide bar 434. A gear 432 is rotatably mounted within the groove 3. The two sides of the gear 432's tooth surface mesh with the tooth surfaces of the two racks 431 respectively. A groove is provided between the end face of one rack 431 and the bottom of the groove 3. The elastic telescopic rod 435 includes a sleeve that is laterally fixed to the bottom of the groove 3 and a rod inserted into the sleeve. One end of the rod is fixed to the end face of one of the racks 431. A compression spring is provided inside the sleeve. The two ends of the compression spring abut against the end face inside the sleeve and the other end face of the rod, respectively. The elastic telescopic rod 435 is used to bring the two adjacent limit bars 41 closer together and reset when the wedge bar 22 is inserted between or pulled out from between the two adjacent limit bars 41.

[0035] The rack 431 is located between the guide bar 434 and the gear 432, and the two limiting bars 41 are located on the ends of the tops of the two racks 431 on different sides.

[0036] The guide strip 434 is parallel to the baffle 44, and the two guide strips 434 are located between the two baffles 44.

[0037] When the wedge-shaped bar 22 falls into the limiting groove under the weight of the scanner, and the inclined surface at the bottom of the protrusion contacts the boundary opposite to the top of the limiting bar 41, it pushes the limiting bar 41 away from the wedge-shaped bar 22 and simultaneously pushes the elastic telescopic rod 435 to contract and accumulate elastic force. As the scanner continues to fall, when the widest part of the protrusion is completely inside the groove 42, the inclined surface at the top of the protrusion contacts the boundary opposite to the top of the limiting bar 41, and the elastic telescopic rod 435 accumulates elastic force. Under the push of the elastic force, the limiting strip 41 is brought close to the support column 21. After the wedge strip 22 falls completely between the two limiting strips 41, the two limiting strips 41 are completely reset under the push of the elastic force accumulated by the elastic telescopic rod 435, thereby constraining the wedge strip 22 between the two limiting strips 41. Through the interlocking effect of the convex strip and the strip groove 42 in the horizontal direction, the scanner can be prevented from slipping off the table when affected by horizontal external force, thus improving the stability and firmness of the scanner on the table.

[0038] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the top of the opposite surfaces of two adjacent limiting strips 41 are both inclined surfaces, and the inclined surfaces are located between the boundary of the top of the strip groove 42 and the top of the limiting strip 41.

[0039] The angle between the inclined surface and the vertical surface is greater than 0° and less than 45°, and the two inclined surfaces are in an inverted V-shape. The minimum distance between the two inclined surfaces is greater than the width of the bottom of the wedge strip 22. This design reduces the resistance of the wedge strip 22 in pushing the limiting strip 41 when the scanner is lowered or picked up, making it easier to pick up or put down, improving the user experience, and automatically centering the wedge strip 22 to fall between the two limiting strips 41.

[0040] Working principle: When lowering the scanner, the bottom of the wedge 22 is first aligned with the two corresponding limiting strips 41. As the scanner falls, the inclined surfaces at the bottom of the protrusions on both sides of the wedge 22 first abut against the inclined surfaces at the top of the limiting strips 41. This causes the horizontal component of the scanner's weight to push the limiting strips 41 away from the support column 21. With the linkage of the linkage 43, the two limiting strips 41 move away from each other. Simultaneously, the elastic telescopic rod 435 accumulates elastic force. When the widest part of the protrusions on both sides of the wedge 22 is fully within the range of the slot 42, the inclined surfaces at the top of the protrusions gradually engage with the top of the slot 42. During this process, the elastic force accumulated by the elastic telescopic rod 435 pushes the adjacent limiting strips 41 closer to the support column 21. With the power transmission of the gear 432 and rack 431, the two limiting strips 41 are driven to move closer together and reset. This completely clamps the wedge 22 between the two limiting strips. Between 41, and through the interlocking state between the protrusion on the wedge 22 and the strip groove 42, and with the distance between one of the limiting bars 41 and one of the inner walls of the groove 3 in its moving direction being equal to the moving distance of the limiting bar 41, so as to limit the amount of movement of the limiting bar 41, so that when the tail wire on the bar handle is pulled by external force, the bar can be prevented from making large displacements, thus preventing it from slipping off the table and breaking. When the bar is picked up for use, the inclined surface of the top of the protrusion on the wedge 22 first abuts against the inclined surface of the top of the limiting bar 41 and the top of the inside of the strip groove 42. As the bar is picked up, the limiting bar 41 is gradually pushed away from the support column 21. At the same time, the elastic telescopic rod 435 accumulates elastic force until the widest part of the protrusion is completely inserted between the inclined surfaces of the tops of the two limiting bars 41. The elastic force accumulated by the elastic telescopic rod 435 pushes the limiting bar 41 back to its original position, so the bar can be picked up for use easily.
