Abstract
Description
Technical Field
[0001] This utility model relates to the field of barcode scanner technology, and in particular to a barcode scanner fixing mechanism. Background Technology
[0002] By combining barcode scanners with barcodes or QR codes, users can scan the corresponding barcodes or QR codes on each item to retrieve detailed information about the item. This greatly improves the efficiency of data retrieval when items are put into storage, taken out of storage, or sold. As a result, it is widely used in industries that require reading a large amount of item information, such as logistics, warehousing, and physical retail stores.
[0003] When using existing barcode scanners, users either pick up the scanner while it is upright or place it upright on the holder. During this process, the standing user needs to press down on their wrist and bend their fingers to hold it horizontally. This causes the muscles in the wrist to become tense, and over time, this can lead to significant discomfort in the wrist. Utility Model Content
[0004] In view of this, the purpose of this utility model is to propose a barcode scanner fixing mechanism to solve the problem that when a standing user picks up a barcode scanner or places it upright on a barcode holder, they need to press down on their wrist and bend their fingers to hold it horizontally, which causes tension in the wrist muscles. Over time, this can lead to significant discomfort in the wrist.
[0005] To achieve the above objectives, this utility model provides a barcode scanner fixing mechanism, including a support column and a mounting base disposed at the bottom of the support column. The fixing mechanism further includes:
[0006] A mounting base fixed to the top of a support column and a mounting slot provided on the mounting base, the mounting slot being used to place the scanner.
[0007] A limiting part is provided outside the support base. The limiting part includes a bushing fixed to the outside of the support base and a horizontal shaft rotating inside the bushing. Limiting rods are fixed at both ends of the horizontal shaft. An actuating rod is fixed at one end of the horizontal shaft along its horizontal radial direction. A torsion spring is provided between the outside of the horizontal shaft and the bushing. When the scanning gun is placed horizontally into the support groove, the downward-moving scanning gun will cause the actuating rod to deflect downward and drive the limiting rod to deflect synchronously towards the scanning gun, so that the scanning gun is limited and fixed in the support groove.
[0008] Preferably, the fixing mechanism further includes a through groove connecting the outside of the support base and the inside of the support groove, the through groove being located on both sides of the support groove opposite to the limiting part, the through groove being used to hold the barcode scanner in a horizontal position and pick it up.
[0009] Preferably, the slot is located between the two end faces of the shelf, and the slot corresponds to the user's right hand.
[0010] Preferably, the fixing mechanism further includes a support bracket fixed to the bottom of one end face of the support base, the support bracket being located below the trigger rod, the support bracket being used to support the head of the scanner when the scanner is placed horizontally in the support slot.
[0011] Preferably, the curvature of the limiting rod matches the outside of the bar grip of the scanner, and the free ends of the limiting rod and the trigger rod point upward and laterally, respectively.
[0012] Preferably, the mounting base includes a base and a threaded post fixed to the top of the base. A vertical through hole is connected between the top and bottom of the threaded post. A connecting rod is inserted into the vertical through hole. The top of the connecting rod is fixed to the bottom of the support post. The bottom of the base has a cavity. A suction cup membrane is fixed between the bottom of the cavity and the boundary of the bottom of the base. The bottom of the connecting rod is fixed at the midpoint of the top of the suction cup membrane. A threaded sleeve is threaded onto the outer thread of the threaded post.
[0013] Preferably, the diameter of the base is greater than or equal to the total length of the barcode scanner, so that the vertical projection of the barcode scanner is located within the range of the base.
[0014] Preferably, the threaded sleeve is located between the bottom of the support column and the top of the base, and the diameter of the threaded sleeve is smaller than the diameter of the bottom of the support column.
[0015] The beneficial effects of this utility model are:
[0016] This invention features vertically positioned limiting rods at both ends of a horizontal axis and a horizontally positioned trigger rod at one end of the horizontal axis. The trigger rod and one of the limiting rods together form a V-shape. The scanner is simply placed horizontally in the slot. Before scanning, as it falls into the slot, it first contacts the trigger rod, causing the trigger rod to deflect downwards under the weight of the scanner. The trigger rod then drives the two limiting rods to deflect horizontally from above, pressing them against the outside of the scanner and horizontally fixing it in the slot. This allows for easy, natural wrist movement to pick up the scanner, making the picking and placing actions more ergonomic and comfortable. Furthermore, by twisting the threaded sleeve, the connecting rod can be raised or lowered to increase or decrease the negative pressure between the suction cup and the table, facilitating quick and easy installation or removal of the base and allowing for convenient changes to the base's position.

[0025] 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.

[0027] like Figures 1 to 5 As shown, a barcode scanner fixing mechanism includes a support column 1 and a mounting base 7 disposed at the bottom of the support column 1. The fixing mechanism also includes:
[0028] The support base 2 is fixed to the top of the support column 1 and the support groove 3 is provided on the support base 2. The support groove 3 is used to place the scanner.
[0029] A limiting part 5 is provided outside the shelf 2. The limiting part 5 includes a bushing 51 fixed to the outside of the shelf 2 and a horizontal shaft 52 rotating inside the bushing 51. Limiting rods 54 are fixed at both ends of the horizontal shaft 52. The outer side of the limiting rods 54 is fixedly covered with an anti-slip layer. An actuating rod 55 is fixed at one end of the horizontal shaft 52 along its horizontal radial direction. A torsion spring 53 is provided between the outer side of the horizontal shaft 52 and the bushing 51. When the scanner is placed horizontally into the shelf groove 3, the downward movement of the scanner will cause the actuating rod 55 to deflect downward and drive the limiting rod 54 to deflect synchronously towards the scanner, so that the scanner is limited and fixed in the shelf. The groove 3 allows standing users to grip the scanner handle from a more comfortable height, maintaining a natural vertical wrist position, and then pick it up. This makes the entire placement and picking-up action more ergonomic, improving the comfort of placement and retrieval. The two limiting rods 54 can also limit and fix the scanner in the groove 3. Furthermore, the friction between the protective layer on the limiting rods 54 and the scanner restricts the scanner's freedom of movement in directions other than vertically upward, improving the stability and firmness of the scanner after placement and preventing it from easily falling due to external impact.
[0030] like Figure 1 and Figure 3 As shown, the fixing mechanism also includes a through groove 4 connecting the outside of the support 2 and the inside of the support groove 3. The through groove 4 is located on both sides of the support groove 3 opposite to the limiting part 5. The through groove 4 is used to hold the barcode scanner in a horizontal position and pick it up.
[0031] The slot 4 is located between the two end faces of the shelf slot 3, and the slot 4 corresponds to the user's right hand. This design allows the standing user to naturally lower their wrist to grasp the scanner placed horizontally in the shelf slot 3, rather than holding the scanner upright with their wrist bent upwards. The former is more in line with the human dynamics of a standing person, improving the comfort of picking up the scanner. Furthermore, the horizontal placement also makes it easy for the user to place the scanner into the shelf slot 3 without having to precisely align it and place it upright on the matching scanner holder, which also improves the ease of placing the scanner.
[0032] like Figures 1 to 4 As shown, the fixing mechanism also includes a support bracket 6 fixed to the bottom of one end face of the mounting base 2. The support bracket 6 is located below the trigger rod 55. The support bracket 6 is used to support the head of the scanning gun when the scanning gun is placed horizontally in the mounting slot 3, so as to avoid the problem of unstable center of gravity when the scanning gun is placed horizontally, and also to improve the stability of the scanning gun after placement.
[0033] like Figure 3 and Figure 4 As shown, the curvature of the limiting rod 54 matches the outside of the bar grip of the scanner, and the free ends of the limiting rod 54 and the trigger rod 55 point upward and laterally, respectively. This design allows the scanner to press against the trigger rod 55 when it is placed into the mounting slot 3, causing it to deflect downward under the pressure of its own weight. This deflection is then synchronously driven by the horizontal axis 52 to the two limiting rods 54 from top to horizontal. Finally, after the scanner is completely placed in the mounting slot 3, the limiting rod 54 presses against the scanner, thus fixing it in place. There is no additional resistance when picking up the scanner, improving the ease of handling. Furthermore, the torsion of the torsion spring 53 causes the limiting rod 54 and the trigger rod 55 to reset synchronously.
[0034] like Figures 3 to 5 As shown, the mounting base 7 includes a base 71 and a threaded post 74 fixed to the top of the base 71. A vertical through hole 75 is connected between the top and bottom of the threaded post 74. A connecting rod 76 is inserted into the vertical through hole 75. The top of the connecting rod 76 is fixed to the bottom of the support post 1. The bottom of the base 71 is provided with a cavity 72. A suction cup membrane 73 is fixed between the bottom of the cavity 72 and the boundary of the bottom of the base 71. The bottom of the connecting rod 76 is fixed at the midpoint of the top of the suction cup membrane 73. A threaded sleeve 77 is threaded onto the outside of the threaded post 74.
[0035] The diameter of the base 71 is greater than or equal to the total length of the barcode scanner, so that the vertical projection of the barcode scanner is within the range of the base 71.
[0036] The threaded sleeve 77 is located between the bottom of the support column 1 and the top of the base 71, and the diameter of the threaded sleeve 77 is smaller than the diameter of the bottom of the support column 1.
[0037] This design allows the base 71 to be pressed firmly against the tabletop. By twisting the threaded sleeve 77, the connecting rod 76 can be moved up or down, pulling the suction cup membrane 73 upwards and causing it to elastically deform. This expands the cavity volume between the suction cup membrane 73 and the tabletop, increasing the negative pressure suction between them and fixing the base 71 to the tabletop. Alternatively, when the threaded sleeve 77 moves downwards, the connecting rod 76 moves downwards under the elastic force of the suction cup membrane 73, reducing the cavity volume between the suction cup membrane 73 and the tabletop, thus reducing the negative pressure suction. This facilitates quick and easy installation or removal of the base and makes it convenient to change the fixed position of the base.
[0038] Working principle: When the scanner is placed horizontally in the mounting slot 3, the downward movement of the scanner will cause the trigger rod 55 to deflect downwards, which in turn drives the two limiting rods 54 to deflect synchronously from top to horizontal through the horizontal axis 52. After the scanner is completely in the mounting slot 3, the limiting rods 54 press against the scanner, fixing it in place within the mounting slot 3. Combined with the significant friction between the protective layer on the limiting rods 54 and the scanner, this restricts the scanner's freedom of movement in all directions except vertically upwards, improving its stability and resistance to external forces. This prevents it from easily falling due to external influences. Furthermore, when picking up the scanner, a standing user only needs to let their wrist hang naturally to grasp and lift it, making operation simple and efficient. Furthermore, it conforms to human ergonomics when a person is standing, making the action of grasping and placing the scanner comfortable and easy. The base 71 is pressed firmly against the table, and by twisting the threaded sleeve 77 up and down, the connecting rod 76 can be raised or lowered, causing it to pull the suction cup membrane 73 upward and cause it to elastically deform, expanding the cavity volume between the suction cup membrane 73 and the table. This increases the negative pressure suction between the suction cup membrane 73 and the table, thus fixing the base 71 to the table. Alternatively, when the threaded sleeve 77 moves down, the connecting rod 76 moves downward under the elastic force of the suction cup membrane 73, reducing the cavity volume between the suction cup membrane 73 and the table, thereby reducing the negative pressure suction between the two. This facilitates quick and easy installation or removal of the base, and makes it convenient to change the fixed position of the base.
