Description

Technical Field

[0001] The utility model relates to the technical field of protective equipment, in particular to a position adjustment mechanism of a strap fixing frame for protective glasses and the protective glasses. Background Art

[0002] Protective glasses can be used to prevent wind, sand, smoke, external impact, chemicals or optical radiation from damaging the wearer's eyes. There are many types of protective glasses, such as snow goggles, windproof goggles, etc.

[0003] In order to ensure the protective effect of protective glasses, protective glasses are generally connected with straps so that users can wear the protective glasses stably without holding the hands.

[0004] However, due to differences in head shape and facial features among different users, the protective glasses are not effectively fixed on the user's head by straps. Utility Model Content

[0005] In order to solve at least one of the above technical problems, the inventors adjusted the structure of protective glasses and found that the main reason for the poor performance of protective glasses when they are fixed to the user's head with straps is that the general straps are directly fixed to the frame of the protective glasses, without an adjustment mechanism, and thus poor applicability. Based on the above findings, the inventors conceived the idea of ​​introducing a position adjustment mechanism on the frame of the protective glasses, and the straps are set on the frame of the protective glasses through the position adjustment mechanism. Thus, the position of the straps relative to the frame can be adjusted by the position adjustment mechanism to adapt to different users and improve the performance. To this end, according to one aspect of the utility model, a position adjustment mechanism for a strap fixing frame for protective glasses is provided.

[0006] The position adjustment mechanism of the strap fixing frame for protective glasses includes a frame body, which is used to be connected to the strap and is configured to be able to move between a first position and a second position relative to the frame of the protective glasses; and a locking structure, which is configured to be able to lock or unlock the frame body moving between the first position and the second position relative to the frame.

[0007] Therefore, when the strap is set on the frame of the protective glasses through the strap fixing frame position adjustment mechanism, the position of the frame relative to the frame can be adjusted between the first position and the second position when the locking structure unlocks the frame relative to the frame, so that the strap can better adapt to different users; and after the position of the frame relative to the frame is adjusted to an appropriate position, the frame can be locked relative to the frame through the locking structure to ensure a stable use effect.

[0008] In some embodiments, the locking structure includes at least two first slots provided on the frame; and a buckle provided on the frame body, movable between a first set position adapted to fit the first slots and a second set position located outside the first slots. Thus, the frame body and the frame can be locked by engaging the first slots with the buckle; and the frame body and the frame can be unlocked by removing the buckle from the first slots. Furthermore, the locking structure formed by the first slots and the buckle allows for quick locking and unlocking of the frame body and the frame without the need for external tools, resulting in convenient operation.

[0009] In some embodiments, based on the locking structure being implemented as a first slot and a buckle, the frame is provided with a restraining structure that provides resistance to the buckle's movement when it moves between the first and second positions. Thus, compared to other positions, the buckle can be more stably positioned in the first and second positions, and will not easily switch between the first and second positions, thereby ensuring the stability of the locking structure in locking the frame to the frame.

[0010] In some embodiments, on the basis of the restriction structure provided on the frame, a first channel is provided on the frame to provide a guide for the buckle to move between the first set position and the second set position; the first channel includes a first mating segment and a second mating segment corresponding to the first set position and the second set position of the buckle, respectively, and adapted to the buckle, and a connecting segment connecting the first mating segment and the second mating segment; the restriction structure is implemented so that the width of the connecting segment is smaller than the width of the buckle, and its side wall can produce elastic deformation.

[0011] Therefore, by setting the first channel on the frame to include a first mating segment and a second mating segment adapted for the buckle, and a connecting segment connecting the first mating segment and the second mating segment and having a width smaller than the width of the buckle, the first channel can provide guidance for the movement of the buckle between the first set position and the second set position while also preventing the buckle from moving arbitrarily between the first set position and the second set position, thereby simplifying the structure of the restriction structure.

[0012] In some embodiments, in addition to providing a restricting structure on the first channel that guides the movement of the buckle, a second channel is provided on both sides of the frame in the guiding direction of the connecting section, and the frame is made of a plastic material to enable elastic deformation of the side walls of the connecting section. Thus, the side walls of the connecting section can be elastically deformed while maintaining a simple frame structure. And / or, in addition to implementing the locking structure as a first slot and a buckle, a wrench is provided on the side of the buckle facing away from the first slot, and the wrench extends out of the surface of the frame. Thus, the buckle can be moved between the first set position and the second set position by turning the wrench without affecting the engagement of the buckle with the first slot.

[0013] In some embodiments, in addition to the wrench provided on the buckle, the outer surface of the frame is further provided with a third channel, arranged along the guide direction of the first channel and adapted to accommodate the wrench. Thus, an operator can move the third channel according to the guidance of the third channel, thereby driving the buckle to move between the first and second set positions. Alternatively, the frame may include a first body and a second body; the first and second channels are provided on the first body, and together form a guide channel; a guide block is connected to the buckle; and the guide channel provides the same guidance to the guide block as the first channel, thereby facilitating the buckle to move between the first and second set positions relative to the frame.

[0014] In some embodiments, in addition to the locking structure being implemented as a first slot and a buckle, the frame is further provided with a blocking portion for limiting the movement of the frame between the first position and the second position. Thus, the blocking portion on the frame can quickly determine the first and second positions of the frame, thereby improving operator efficiency.

[0015] In some embodiments, the locking structure is implemented as a first slot and a buckle, and the frame is hinged to the frame to enable movement relative to the frame, with the hinge axis between the frame and the frame being approximately vertical. Thus, by rotating the frame relative to the frame, the angle between the frame and the frame can be adjusted, thereby achieving the purpose of adjusting the strap.

[0016] In some embodiments, the frame is hinged to the frame to enable movement relative to the frame, and at least two first latching slots are distributed along the circumference of the hinge axis between the frame and the frame. Thus, the frame can be locked relative to the frame after being rotated a certain angle relative to the frame by snapping into different first latching slots distributed along the circumference of the hinge axis between the frame and the frame, thereby stably adjusting the angle between the frame and the frame.

[0017] According to another aspect of the present invention, protective glasses are provided, comprising a frame and the aforementioned strap fixing frame position adjustment mechanism for protective glasses, wherein the frame of the strap fixing frame position adjustment mechanism is disposed on the frame.

[0018] Therefore, when the locking structure unlocks the frame relative to the frame, the position of the frame relative to the frame can be adjusted between the first position and the second position, so that the strap can better adapt to different users; and after the position of the frame relative to the frame is adjusted to a suitable position, the frame can be locked relative to the frame by the locking structure to ensure a stable use effect.

[0032] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are 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.

[0033] Figures 1 to 8 The figure schematically shows a position adjustment mechanism of a strap fixing frame for protective glasses according to an embodiment of the present invention.

[0034] like Figures 3 to 6 As shown, the position adjustment mechanism of the strap fixing frame for protective glasses includes a frame 20 and at least two first slots 51 integrally formed or processed on the frame 40 of the protective glasses. The frame 20 is used to connect with the strap 30. Figure 1 and Figure 2 As shown, the frame 20 is hinged to the frame 40 via a hinge shaft 42, and can move between a first position and a second position in a manner that it can swing relative to the frame 40. Figure 3 、 Figure 4 、 Figure 7 and Figure 8As shown, the position adjustment mechanism of the strap fixing frame for protective glasses further includes a buckle 52, which is movably provided on the frame 20 between a first setting position and a second setting position relative to the frame 20, and when the buckle 52 is in the first setting position, the buckle 52 is adapted to the first card slot 51 to achieve the engagement of the buckle 52 with the first card slot 51; when the buckle 52 is in the second setting position, the buckle 52 is located outside the first card slot 51 to achieve the separation of the buckle 52 from the first card slot 51. At least one first card slot 51 is configured so that when the buckle 52 is engaged therewith, the frame 20 is locked in the first position relative to the frame 40, as shown in FIG. Figure 2 As shown; at least one first card slot 51 is configured so that when the buckle 52 is engaged with it, the frame 20 is locked in the second position relative to the frame 40; at least one first card slot 51 can also be provided between the two first card slots 51 as needed to achieve the locking of the frame 20 relative to the frame 40 between the first position and the second position.

[0035] Therefore, when the strap 30 is set on the frame 40 of the protective glasses through the strap fixing frame position adjustment mechanism, the frame 20 and the frame 40 can be unlocked by moving the buckle 52 out of the first slot 51, so as to adjust the position of the frame 20 relative to the frame 40 between the first position and the second position, so that the strap 30 can better adapt to different users; after the position of the frame 20 relative to the frame 40 is adjusted to an appropriate position, the frame 20 and the frame 40 can be locked by engaging the first slot 51 with the buckle 52 to ensure a stable use effect; moreover, the operation process is convenient and does not require the aid of external tools.

[0036] In some embodiments, as Figure 3 and Figure 4 As shown, the first slot 51 and the buckle 52 constitute a locking structure 50 of an embodiment of the present invention, which can lock or unlock the frame 20 moving between the first position and the second position relative to the frame 40.

[0037] As another embodiment of the locking structure 50, the locking structure 50 includes positioning holes provided on the frame 40 and the frame 20, and a pin capable of passing through the positioning holes in the frame 40 and the frame 20. The number of positioning holes in at least one of the frame 40 and the frame 20 is at least two, so that when the pin passes through different positioning holes in the frame 40 and the frame 20, the frame 20 can be locked relative to the frame 40 when the frame 20 moves to different positions relative to the frame 40. In some preferred embodiments, at least two positioning holes in the frame 40 and / or the frame 20 are distributed along the circumference of the hinge axis 42 between the frame 20 and the frame 40. Thus, by inserting the pin into different positioning holes distributed along the circumference of the hinge axis 42 between the frame 20 and the frame 40, the frame 20 can be locked relative to the frame 40 after being rotated a certain angle relative to the frame 40, thereby stably adjusting the angle between the frame 20 and the frame 40.

[0038] In some preferred embodiments, Figure 8 As shown, the frame 20 is integrally formed or processed with a first channel 211 that provides a guide for the buckle 52 to move between the first set position and the second set position. As one preferred embodiment of the first channel 211, continue to refer to Figure 8 As shown, the first channel 211 includes a first matching segment 2111 corresponding to the first setting position of the buckle 52 and adapted to the buckle 52, a second matching segment 2112 corresponding to the second setting position of the buckle 52 and adapted to the buckle 52, and a connecting segment 2113 connecting the first matching segment 2111 and the second matching segment 2112; the width of the connecting segment 2113 is smaller than the width of the buckle 52, and its side wall can produce elastic deformation to provide resistance for the buckle 52 to move between the first setting position and the second setting position. As a result, the first channel 211 can provide guidance for the movement of the buckle 52 between the first setting position and the second setting position, while also preventing the buckle 52 from moving between the first setting position and the second setting position at will, so as to ensure the stability of the locking structure 50 in locking the frame 20 on the frame 40. As one of the specific embodiments in which the side wall of the connecting segment 2113 can produce elastic deformation, as shown in FIG. Figure 8 As shown, second channels 212 are provided on both sides of the guide direction of the connecting section 2113 of the frame 40, and the frame body 20 is made of plastic material so that the side walls of the connecting section 2113 can produce elastic deformation. Thus, the side walls of the connecting section 2113 can produce elastic deformation while ensuring the simplicity of the structure of the frame body 20.

[0039] In some embodiments, as Figure 8 As shown, the connecting section 2113 whose side wall can generate elastic deformation constitutes the limiting structure 60 (also called the shifting structure) of one embodiment of the present invention, so as to obtain a limiting structure 60 with a simplified structure.

[0040] In some preferred embodiments, Figure 3 and Figure 4 As shown, on the basis of the locking structure 50 being implemented as a first slot 51 and a buckle 52, a wrench 53 is further provided on the side of the buckle 52 facing away from the first slot 51, and the wrench 53 extends out of the surface of the frame 20. Thus, the buckle 52 can be moved between the first set position and the second set position by pulling the wrench 53 without affecting the engagement of the buckle 52 with the first slot 51. Further preferably, as Figure 1 and Figure 2 As shown, the outer surface of the frame body 20 is further provided with a third channel 221 arranged along the guide direction of the first channel 211 and adapted to the wrench 53. Thus, the operator can pull the third channel 221 according to the guide direction of the third channel 221, thereby driving the buckle 52 to move between the first set position and the second set position.

[0041] In some preferred embodiments, Figure 2 、 Figure 5 and Figure 6 As shown, the frame 40 is also integrally formed, processed, or connected with a blocking portion 41 for limiting the movement of the frame 20 between the first position and the second position. Therefore, the blocking portion 41 on the frame 40 can quickly determine the first position and the second position of the frame 20, thereby improving the operator's operating efficiency.

[0042] In some preferred embodiments, the hinge axis 42 connecting the frame 20 and the eyeglass frame 40 is approximately vertical. In this application, "vertical" refers to the vertical position of the eyeglass frame 40 during normal use. Thus, by rotating the frame 20 relative to the eyeglass frame 40, the angle between the frame 20 and the eyeglass frame 40 can be adjusted, thereby achieving the purpose of adjusting the strap 30.

[0043] In some preferred embodiments, Figure 5 and Figure 6 As shown, at least two first latching slots 51 are distributed along the circumference of the hinge axis 42 between the frame 20 and the frame 40. Thus, the frame 20 can be locked relative to the frame 40 after being rotated a certain angle relative to the frame 40 by engaging the buckles 52 in different first latching slots 51 distributed along the circumference of the hinge axis 42 between the frame 20 and the frame 40, thereby stably adjusting the angle between the frame 20 and the frame 40.

[0044] In some preferred embodiments, in order to facilitate the realization of the buckle 52 in the first setting position and the second setting position relative to the frame 20, as shown in FIG. Figure 4 and Figure 5As shown, the frame 20 includes a first body 21 and a second body 22; the first channel 211 and the second channel 212 are integrally formed or processed on the first body 21; the third channel 221 is integrally formed or processed on the second body 22; the first body 21 and the second body 22 together form a guide channel 23, and a guide block 54 is connected to the buckle 52, and the guide channel 23 provides the guide block 54 with the same guiding function as the first channel 211. In some specific implementations, the guide channel 23 is implemented in the following way: a first sink 222 is integrally formed or processed on the second body 22, and the first body 21 and the second body 22 are connected and cover the opening of the first sink 222 to form the guide channel 23 in the first sink 222, thereby ensuring the flatness of the surface of the formed frame 20. One of the connection methods of the first body 21 and the second body 22 is: detachable connection, for example, the buckle 52 is interference fit with the first channel 211; for example, Figure 10 As shown, the first body 21 and the second body 22 are connected by screws. In some specific embodiments, a through hole 213 can be machined or integrally formed on the first body 21, and a screw hole that is compatible with the through hole can be machined or integrally formed at a position corresponding to the first body 21 on the second body 22. The screw 24 passes through the through hole 213 on the first body 21 and then screws into the screw hole on the second body 22 to achieve a detachable connection between the first body 21 and the second body 22, thereby improving the stability and firmness of the connection between the first body 21 and the second body 22. Another connection method between the first body 21 and the second body is to achieve a non-detachable connection between the first body 21 and the second body 22, for example, the first body 21 and the second body 22 are fixedly connected by ultrasonic welding; for example, the first body 21 and the second body 22 are fixedly connected by gluing.

[0045] Figure 9 Schematically shows a pair of protective glasses according to an embodiment of the present invention. Figure 9 As shown, the protective glasses include a frame 40 and the aforementioned strap fixing frame position adjustment mechanism for protective glasses. The frame 20 of the strap fixing frame position adjustment mechanism is disposed on the frame 40. Thus, when the locking structure 50 unlocks the frame 20 relative to the frame 40, the position of the frame 20 relative to the frame 40 can be adjusted between a first position and a second position, thereby enabling the strap 30 to better adapt to different users. Furthermore, after the frame 20 is adjusted to a suitable position relative to the frame 40, the locking structure 50 can be used to lock the frame 20 relative to the frame 40 to ensure stable use.

[0046] In the present invention, connection or installation, unless otherwise specified, refers to a fixed connection. Fixed connections can be implemented as either removable or non-removable connections commonly used in the prior art. Removable connections can be implemented using existing technologies, such as threaded connections or key connections. Non-removable connections can also be implemented using existing technologies, such as welding or gluing.

[0047] The above descriptions are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, and these all fall within the scope of protection of the present invention.
