Description

Technical Field

[0001] The utility model relates to the technical field of neck hanging readers, in particular to a detachable neck hanging reader. Background Art

[0002] A neck reader is a device that hangs around the user's neck for easy reading. It's typically equipped with a magnifying lens or Fresnel lens to visually magnify the text being read. Some users also use it to magnify needle holes for easier threading. Compared to traditional handheld magnifiers, it allows users to use their hands free, making it more convenient.

[0003] Many structures, such as the Chinese utility model "Neck-hanging desktop handheld three-in-one magnetic magnifier" with announcement number CN219105275U, use a magnetic connection structure and a neck-hanging design, making it easy for users to carry and use. When the magnifier is removed, it can be used for both handheld and desktop support, meeting the needs of use in different scenarios, providing convenience for users and effectively reducing the purchase and use costs of magnifiers. However, when used as a neck-hanging device, the magnetic structure is relatively easy to remove and install, but it can easily cause the magnifier to detach from the neck-hanging bracket (flexible iron bracket), causing damage to the magnifier if it accidentally falls, which needs to be improved. Utility Model Content

[0004] In order to overcome the above-mentioned shortcomings, the present invention aims to provide a technical solution that can solve the above-mentioned problems.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a detachable neck-hanging reader, comprising a neck-hanging bracket, a lens bracket detachably connected to the neck-hanging bracket, a reading lens mounted on the lens bracket, a connector connected to the lens bracket, a plug-in fitting connected to the neck-hanging bracket, a plug-in recess formed on the plug-in fitting for inserting at least part of the connector; a mounting groove is formed on the outer side surface of the connector, a lock bead and an elastic member for elastically pressing the lock bead in the direction of disengaging the mounting groove are mounted on the mounting groove; a locking arc surface that partially cooperates with the lock bead is formed on the inner side surface of the plug-in recess.

[0006] As a further solution of the present invention: an insertion guide groove that cooperates with the locking ball part is formed on an inner side surface of the plug-in recess having a locking arc surface, and the insertion guide groove is formed between the locking arc surface and the external insertion port of the plug-in recess along the plug-in direction of the connector on the plug-in recess.

[0007] As a further solution of the present invention: the inner side surface of the plug-in recess having the locking arc surface is further formed with a connecting groove that connects the insertion guide groove to the external insertion port of the plug-in recess.

[0008] As a further solution of the present invention: a locking block is formed on the inner side surface of the plug-in recess having the locking arc surface and is located between the insertion guide groove and the locking arc surface.

[0009] As a further solution of the present invention, a guiding inclined surface corresponding to the insertion guide groove is formed on the locking block.

[0010] As a further solution of the present invention: the matching width of the insertion guide groove and the locking bead is gradually increased from the external insertion port of the plug-in recess to the locking arc surface.

[0011] Compared with the existing technology, the beneficial effects of this technical solution are: through the plug-in cooperation between the plug-in component and the plug-in matching component, and when plugging in, the lock bead is pressed against the locking arc surface by the elastic component to form an elastic lock, so that the lens bracket is not easily separated from the neck bracket.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1-4 A detachable neck-hanging reader includes a neck-hanging bracket 1 and a lens holder 2 detachably connected to the neck-hanging bracket 1. A reading lens 3 is mounted on the lens holder 2. A connector 4 is connected to the lens holder 2. A mating connector 5 is connected to the neck-hanging bracket 1. The mating connector 5 has a recess 6 formed therein to accommodate at least a portion of the connector.

[0022] The outer surface of the connector 4 is formed with a mounting groove 7, which houses a locking bead 8 and an elastic member 9 for elastically pressing the locking bead 8 out of the mounting groove 7. The inner surface of the insertion recess 6 is formed with a locking arc 8 that partially mates with the locking bead 8. The connector 4 is mated with the mating component 5, and during mating, the elastic member 9 presses the locking bead 8 against the locking arc 10, creating an elastic lock that prevents the lens holder 2 from being easily separated from the neck halter 1.

[0023] In some embodiments, the reading lens 3 may be a convex magnifying lens or a Fresnel lens.

[0024] like Figure 2 、 3 As shown, in some embodiments, the main body formed by the lens holder 2 and the connector 4 is obtained by joining two half shells. When joining, the reading lens 3, the elastic member 9, and the locking bead 8 can be installed in corresponding positions.

[0025] The mounting groove 7 passes through one of the half shells, and the mounting groove 7 is configured as a constriction on the outer side of the penetrated half shell to prevent the locking ball 8 from falling out of the mounting groove 7 under the elastic action of the elastic member 9 .

[0026] In some embodiments, the neck-hanging bracket 7 is a bracket that can be shaped after being bent accordingly, such as a neck-hanging bracket including a flexible wire or a flexible tube. When the user hangs the neck-hanging reader around the neck, the user can quickly and conveniently adjust the angle of the reading lens.

[0027] In some embodiments, the elastic member 9 is a compression spring, one pressing end of the compression spring abuts against the inner top wall of the installation groove 7 , and the other pressing end of the compression spring abuts against the locking bead 8 .

[0028] In the embodiment of the present invention, an insertion guide groove 11 is formed on an inner side surface of the plug-in recess 6 having a locking arc surface, which cooperates with the locking bead 8. The insertion guide groove 11 is formed between the locking arc surface 10 and the outer insertion opening of the plug-in recess 6 along the plug-in direction of the plug-in connector 4 plugged into the plug-in recess 6. When plugging, the insertion guide groove 11 cooperates with the locking bead 8 to form a guide during insertion, making plugging more convenient.

[0029] A connecting groove 12 is formed on the inner side surface of the plug-in recess 6 having the locking arc surface 10 so that the insertion guide groove 11 is connected to the external insertion port of the plug-in recess 6 .

[0030] A locking block 13 is formed on the inner side of the insertion recess 6, which has a locking arc, and is positioned between the insertion guide groove 11 and the locking arc 10. A guiding slope 14 is formed on the locking block 13, corresponding to the insertion guide groove 11. The provision of the locking block 13 and the guiding slope 14 not only prevents the lens holder 2 from being separated from the neck holder 1 during elastic locking, but also facilitates insertion.

[0031] like Figure 4 As shown, further, the fitting width between the insertion guide groove 11 and the locking ball 8 is gradually increased from the external insertion opening of the plug-in recess 6 to the locking arc surface 10. When the locking ball 8 enters the insertion guide groove 11 and fits with the insertion guide groove 11, the change in the fitting width of the insertion guide groove 11 is set so that: under the pressure of the elastic member 9, the locking ball 8 has a "stress tendency to move from a position with a small fitting width to a position with a large fitting width on the insertion guide groove 11". That is, when the locking ball 8 is closer to the external insertion opening of the plug-in recess 6 on the insertion guide groove 11, the space on the insertion guide groove 11 that can accommodate the locking ball 8 becomes smaller and smaller (i.e., the fitting width becomes smaller and smaller), forcing the locking ball 8 to move toward entering the installation groove 7, that is, the elastic member 9 is pressed more and more tightly by the locking ball 8. On the contrary, when the locking ball 8 is closer to the locking block 13 on the insertion guide groove 11, the elastic pressure of the elastic member 9 can be gradually released and restored. As a result, when the connector 4 is inserted into the insertion recess 6 and the locking bead 8 enters the insertion guide groove 11, under the action of the insertion guide groove 11, the locking bead 8 and the elastic member 9, the connector 4 has a force tendency toward the insertion direction, making it easier to insert and less likely to fall out.

[0032] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
