Description

[0002] A code reading camera can read the information corresponding to an identification code (for example, a barcode, QR code, etc.) on an object by taking a picture of the identification code, thereby quickly identifying materials, products or storage containers. It is widely used in various scenarios such as warehousing, transportation, sales and production workshops.

[0003] Handheld barcode readers usually have a tail wire connected to the end of the handle to realize the communication and power supply functions of the barcode reader. In order to facilitate the quick connection and removal of the barcode reader and the tail wire, and to ensure the connection strength between the tail wire and the barcode reader handle, a locking structure for fixing the tail wire is usually provided at the end of the handle. When installing the tail wire, first open the tail wire locking structure, then insert the tail wire into the socket, and finally lock the tail wire locking structure to prevent the tail wire from coming out when being pulled or vibrated. When removing the tail wire, it is also necessary to open the tail wire locking structure first so that the tail wire can be pulled out.

[0004] However, the tail wire locking structure of the existing code reading camera is often locked by threads or threaded fasteners. When disassembling the tail wire, it is often necessary to twist the tail wire locking structure or remove or loosen the fasteners of the tail wire locking structure one by one to successfully open or lock the tail wire locking structure, resulting in cumbersome steps for disassembling and assembling the tail wire, affecting the convenience of using and maintaining the product.

DETAILED DESCRIPTION

[0070] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments in the implementation manner are intended to be used to explain the present invention and should not be construed as limiting the present invention.

[0071] References to "one embodiment" or "example" or "example" in this specification mean that a particular feature, structure, or characteristic described in conjunction with the embodiment itself may be included in at least one embodiment disclosed herein. The appearance of the phrase "in one embodiment" in various places in the specification does not necessarily refer to the same embodiment.

[0072] The tail wire locking structure of the existing barcode reading camera includes a slider type and a pressure ring type. Among them, in the slider type design, the tail wire locking structure locks the tail wire through the slider and uses a set screw to lock the position of the slider. Therefore, when the slider needs to be moved to remove the tail wire, it often takes a lot of time to unscrew the set screws one by one. When the slider is used to position the inserted tail wire, it also takes time to tighten the set screws, resulting in low efficiency in disassembling and assembling the tail wire;

[0073] In the compression ring design, the tail wire locking structure locks the tail wire through a threaded compression ring. The actual size of the threaded compression ring is very small and not easy to operate. Therefore, when disassembling and assembling the tail wire, it also takes a lot of time to unscrew the threaded compression ring and screw it into the tail wire installation port. In addition, if the compression ring is not tightened, the tail wire may also become loose under working conditions such as vibration, and the reliability of the tail wire locking structure is low.

[0074] In order to solve the above technical problems, as one aspect of the present invention, a tail wire locking structure is provided, such as Figures 1 to 4 As shown, the tail wire locking structure includes a sealed tail seat 1 and a slider 200, the sealed tail seat 1 has a socket 101 for inserting the tail wire 60, the slider 200 is formed with a clamping opening 211 connected with the socket 101, and the slider 200 has a clamping surface a1 facing the inner side of the sealed tail seat 1 (i.e., the side facing the inside of the handle assembly, which is the upward side in the figure) at the edge of the clamping opening 211, the slider 200 is movably connected to the sealed tail seat 1, and the slider 200 can move along the sliding direction (i.e., Figures 1 to 4 The locking position is such that the engaging surface a1 is moved to a locking position corresponding to the position of the socket 101 (i.e., it enters the projection range of the socket 101 along the extending direction of the socket 101). Figure 4 , Figure 6 As shown, and moved to the open position where the engagement surface a1 is offset from the socket 101 (ie, away from the projection range of the socket 101), as shown Figure 3 , Figure 5 As shown;

[0075] The slider 200 is provided with a first connection portion, and the sealing tailstock 1 is provided with a second connection portion, and the first connection portion and the second connection portion can be connected to each other when the slider 200 is located in the locking position.

[0076] It can be understood that the sealing tailstock 1 is used to be sealed and connected with the tail end of the handle assembly, and the slider 200 can slide along the sliding direction. When the slider 200 is in the open position, the tail wire 60 can freely pass through the snap-in opening 211 and insert or leave the socket 101. When the slider 200 is in the locked position, the snap-in surface a1 on one side of the snap-in opening 211 enters the range of the socket 101, and it can abut against the corresponding surface on the tail wire 60 (such as the back of the plug mating part 62 or the side wall of the snap-in structure on the tail wire 60) to prevent the tail wire 60 from escaping from the socket 101, so as to lock the tail wire 60. The first connecting portion and the second connecting portion can be connected to each other when the slider 200 is in the locked position to fix the slider 200 in the locked position. When the pull-out force received by the slider 200 along the sliding direction is greater than a certain threshold, the first connecting portion is disengaged from the second connecting portion, so that the tail wire locking structure is switched to the open state.

[0077] In the tail wire locking structure provided by the present invention, the slider 200 is movably arranged on the sealing tail seat 1, and can slide to switch positions, so that the engaging surface a1 enters the range of the socket 101 and abuts against the tail wire 60 to prevent the tail wire 60 from falling out, or the engaging surface a1 is staggered with the socket 101, so that the tail wire 60 can freely pass through the engaging opening 211 to achieve plugging and unplugging. In addition, the first connecting portion and the second connecting portion can be connected to each other when the slider 200 is in the locking position to keep the position between the slider 200 and the interface bracket 100 fixed, and only disengage when the slider 200 is subjected to a sufficiently large pulling force, thereby keeping the tail wire locking structure in a locked state during normal use.

[0078] The tail wire locking structure provided by the present invention realizes the position of the fixed slider 200 through the first connecting part and the second connecting part, which can effectively ensure the stability of the tail wire locking structure when it is in the locked state; and, when switching the locking and opening states of the tail wire locking structure, only a pulling force needs to be applied to change the position of the slider 200, and there is no need to disassemble and assemble threaded structures such as screws, so that the locking and opening states can be flexibly switched, thereby improving the convenience of disassembling and assembling the tail wire 60, and ensuring the use and maintenance efficiency of the handle assembly and related products using the tail wire locking structure provided by the present invention.

[0079] As an optional embodiment of the present invention, Figures 1 to 4 As shown, the sealed tailstock 1 includes an interface bracket 100 and a tail cover 300. The interface bracket 100 is located on the inner side of the tail cover 300. The interface bracket 100 has a socket 101. The tail cover 300 has an inlet corresponding to the position of the socket 101. The slider 200 can slide along the gap between the interface bracket 100 and the tail cover 300.

[0080] In the embodiment of the present invention, the tail wire 60 is inserted into the tail wire locking structure along the stacking direction of the interface bracket 100, the slider 200 and the tail cover 300. Therefore, when the tail wire 60 is pulled or vibrated, the slider 200 is mainly subjected to the force perpendicular to its sliding direction, which further ensures the stability of the slider 200 when it is in the locked position, and further ensures the stability of the locked state of the tail wire locking structure.

[0081] In some embodiments of the present invention, the first connecting portion and the second connecting portion may be snap-fit ​​structures, specifically, as Figures 1 to 4 , Figure 7 , Figure 8 As shown, the first connecting portion includes a positioning protrusion 212 formed on the slider 200, and the second connecting portion includes a bayonet 102 formed on the interface bracket 100. The positioning protrusion 212 can be inserted into the bayonet 102 when the slider 200 is in the locking position, and can be removed from the bayonet when the pulling force is greater than or equal to a preset pulling force value.

[0082] In other embodiments of the present invention, the first connecting part and the second connecting part may also be other forms of connecting structures. For example, the first connecting part and the second connecting part may be permanent magnets. When the slider 200 is in the locking position, the positions of the first connecting part and the second connecting part are also aligned with each other, so that the relative position of the slider 200 and the interface bracket 100 is kept fixed by the adsorption effect of the first connecting part and the second connecting part. When the pulling force applied to the slider 200 is greater than the preset pulling force value, the slider 200 overcomes the action force between the first connecting part and the second connecting part and moves, so that the engaging surface a1 moves to be offset from the position of the socket 101.

[0083] Alternatively, one of the first connecting part and the second connecting part can be a permanent magnet and the other can be an electromagnet, and the relative position of the fixed slider 200 and the interface bracket 100 is achieved by the adsorption force between the permanent magnet and the electromagnet; or, both can be electromagnets, and the relative position of the fixed slider 200 and the interface bracket 100 is achieved by the adsorption force between the electromagnets.

[0084] As an optional embodiment of the present invention, Figures 1 to 4 , Figure 7 , Figure 8 As shown, the slider 200 has a positioning protrusion 212 on one side facing the interface bracket 100. Figures 1 to 4 As shown, the interface bracket 100 has a snap-in 102 on a side facing the slide 200 .

[0085] As a preferred embodiment of the present invention, Figure 1 , Figure 2 As shown, the side of the positioning protrusion 212 facing away from the slider 200 has a first inclined surface b1, a top plane b2 and a second inclined surface b3 distributed in sequence along the sliding direction of the slider 200, the first inclined surface b1 and the second inclined surface b3 are respectively connected between the top plane b2 and the surface of the slider 200, and when the slider 200 slides to the locking position, the first inclined surface b1 moves toward the bayonet 102, and the angle between the first inclined surface b1 and the surface of the slider 200 is smaller than the angle between the second inclined surface b3 and the surface of the slider 200.

[0086] In an embodiment of the present invention, the positioning protrusion 212 has a first inclined surface b1 along the side moving toward the bayonet 102, and has a second inclined surface b3 along the side moving away from the bayonet 102, and the slope of the first inclined surface b1 is smaller than the slope of the second inclined surface b3. Thus, while utilizing the inclined surface structure to ensure the smoothness of the positioning protrusion 212 being inserted into and removed from the bayonet 102, it also ensures that the side wall of the bayonet 102 blocks the force of the positioning protrusion 212 leaving the bayonet 102, thereby ensuring the stability of the locking state of the tail wire locking structure.

[0087] As an optional embodiment of the present invention, Figure 2As shown, the side wall of the bayonet 102 has a matching inclined surface c1 corresponding to the second inclined surface b3. When the slider 200 is located at the locking position, the matching inclined surface c1 is in contact with the second inclined surface b3.

[0088] In order to ensure the structural strength of the tail wire locking structure, as a preferred embodiment of the present invention, the slider 200 is made of metal material.

[0089] To further ensure the structural strength of the tail wire locking structure, as a preferred embodiment of the present invention, the tail cover 300 is made of metal material.

[0090] As a preferred embodiment of the present invention, Figures 1 to 4 As shown, the interface bracket 100 includes a bracket body 110 and a positioning member 120, the socket 101 is located in the bracket body 110, the positioning member 120 includes a connecting portion 121 and a deformation portion 122 that are interconnected, the connecting portion 121 is fixedly arranged on the side of the bracket body 110 facing the slider 200, the deformation portion 122 is spaced apart from the bracket body 110, and the deformation portion 122 has a snap-on 102.

[0091] In an embodiment of the present invention, the interface bracket 100 includes a bracket body 110 and a positioning member 120, the positioning member 120 has a deformation portion 122 spaced apart from the bracket body 110, and the bayonet 102 is formed on the deformation portion 122. Therefore, when the material of the bracket body 110 and the slider 200 are both selected as hard metal materials, the elastic deformation of the deformation portion 122 can also ensure that the positioning protrusion 212 can be smoothly inserted into and removed from the bayonet 102.
