Description

Technical Field

[0001] The present invention relates to the technical field of goggles, and more particularly to a goggles film rolling system. Background Art

[0002] Goggles, which serve as eye windows, are generally made of high-strength resin materials, which can withstand the impact of external objects, and can prevent fogging and visual misleading. Specifically, they can change the intensity and spectrum of transmitted light to prevent radiation light from causing damage to the eyes. Professional goggles usually have an important design - the adhesive strip layer, which is usually fixed by the film knob on the lens and can be torn off and replaced at any time. Its main function is that when the outside of the lens is affected by dust or rain and other foreign objects, the wearer can tear it off to get a clear view again. One end of the film is usually rolled up with a small round hole, which makes it easy for drivers wearing thick gloves to tear it off. In addition, this film usually has more than one layer, and the driver can tear it off multiple times to get a clear view. Taking into account the traditional film-hanging method of tearing off and replacing, the efficiency of the film is completely determined by the number of attached layers before use, and the convenience of subsequent replacement is largely limited by the tearing method of the film. As a result, existing film-hanging and goggles are usually combined with a semi-automatic film-hanging replacement structure to solve the problem of difficulty in replacing the film when wearing goggles. However, in the use scenario of goggles, when the film is exhausted, the goggles and the film-hanging structure need to be disassembled and replaced.

[0003] The entire disassembly process is cumbersome and the replacement of gloves worn outdoors is difficult and restrictive, which greatly limits the use scenarios and convenience of the existing goggles roll film structure; Based on this, the present invention provides an effective solution to the problems of low convenience in assembly and use of the existing goggles' roll film and poor roll film utilization.

[0008] A further preferred solution is that the film roll end, the sliding step and the film strip opening are angular crossing structures with arched surfaces, and the film strip opening is slightly higher than the sliding step surface.

[0009] A further preferred solution is that a pull handle linked to the clockwork mechanism is arranged outside the wire drum, the pull handle and the clockwork mechanism are connected by a wire rope, and the clockwork mechanism is drivingly connected to the winding shaft.

DETAILED DESCRIPTION

[0018] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, Figure 1-Figure 10 The present invention is further described in detail with specific embodiments. The following embodiments are only examples for implementing the present invention. It must be pointed out that the disclosed embodiments do not limit the scope of the present invention. On the contrary, changes and modifications made without departing from the scope of the present invention are all within the scope of patent protection of the present invention.

[0019] The goggles film rolling system comprises a main frame 1, the main frame 1 is a frame body that fits the curvature of the goggles frame, and the middle of the main frame 1 is hollowed out to form a viewport; A pair of film roll bins 8 are symmetrically fixed to the flanges on both sides of the main frame 1, and the film roll bins 8 are semicircular tubular structures, and a relatively smaller inner tube 9 of a semicircular structure is clamped therein, and a reel 13 is rotatably arranged between the film roll bins 8 and the inner tube 9, and a film roll 6 is wound in the film roll bin 8 on one side, and the head end of the film roll 6 passes through the film roll bin 8, the main frame 1, and is fixed to the reel 13 in the film roll bin 8 on the other side in sequence, so that the film roll 6 is horizontally placed in the viewport in the main frame 1; The outer ends of the film roll bins 8 on both sides are clamped with another semicircular tube bin 2 matching the tube structure, and the inner half of the tube bins 2 on both sides are protruding with an integrally formed mounting seat 3, and the surface opening of the mounting seat 3 is provided with a bolt opening for fixing with the goggles frame; The outer half of the film roll bin 8 and the tube bin 2 is provided with matching wrench clamps 10 and wrench openings, and the main frame 1 and the film roll bin 8 are installed and disassembled with the tube bin 2 through the wrench clamps 10; A wire drum 4 is fixed at the bottom of the tube bin 2 on one side, and a semi-automatic clockwork mechanism is arranged in the wire drum 4; The film rolling system mainly uses the mounting seat 3 as the mounting part with the goggles structure, such as Figure 1 , 2 As shown, a bolt hole is reserved on the front of the goggles structure to assemble and fix the mounting seat 3 with bolts, and then the main frame 1 is assembled on the mounting seat 3 by snapping and fixing, so that the curved frame body of the main frame 1 fits with the edge of the goggles window, and the hollow viewport therein corresponds to the goggles window. The same is true for disassembly, and only the main frame 1 needs to be disassembled to load the film 6; like Figure 2 As shown, matching jaws 10 and jaws are provided on the outer half of the roll film bin 8 and the tube bin 2. The assembly and fastening of the roll film bin 8 and the tube bin 2 are mainly achieved through the integrally formed jaws 10 and the reserved jaws to complete the single-sided fastening and fixing of the roll film bin 8 and the tube bin 2. The jaws 10 can be separated from the jaws of the tube bin 2 by simply pressing them inward, which facilitates the disassembly and assembly operations of the structure when replacing the roll film 6.

[0020] In the film roll system, the film roll 6 is usually packaged as a consumable material and bundled with the reel 13 in an integrated manner. Figure 4 , 5As shown, the two ends of the winding shaft 13 are buckled into the axial hole ends of the inner tube 9 by means of an interlocking and fixing method. The rolled film needs to be loaded into the tube bin 2 that is not connected to the wire drum 4, and the rolled film 6 is pulled through the rolled film bin 8 and the main frame 1 during installation to be wound and fixed with the winding shaft 13 in the rolled film bin 8 on the other side, so that the film surface of the rolled film 6 is placed in the viewport in the middle of the main frame 1. At the same time, since the tube bins 2 for filling on both sides correspond to the curved surface of the main frame 1, the rolled film 6 is in a planar tensioned state in the main frame 1. At the same time, since the winding shafts 13 in the tube bins 2 on both sides are active, in the process of buckling the main frame 1 together with the rolled film 6 to the mounting seat 3, the rolled film 6 can maintain the maximum tension to ensure the complete fit with the mirror surface of the goggles, and at the same time, the rotation of the winding shafts 13 on both sides is used to cooperate with the tension of the rolled film 6 during the bonding process. The change improves the fitting effect and consistency with the goggles when filling and replacing the roll film 6; compared with the existing semi-automatic film replacement method, this method stores the roll film consumables through the main frame 1 and the roll film bin 8, and when the roll film is exhausted, it only needs to be simply disassembled and separated, and the exhausted roll film 6 together with the main frame 1 and the goggles structure can be separated, and the main frame 1 and the roll film bin 8 structure loaded with new roll film 6 can be replaced again, which greatly facilitates the convenience of the entire roll film system when used, and avoids the existing semi-automatic film replacement structure. When the film is exhausted, the goggles and the film structure need to be disassembled and replaced. The whole disassembly process is cumbersome and the replacement of gloves outdoors is difficult and restricted. The practicality of the roll film system is improved. Through the cooperation of various structures, users can replace the roll film more simply and efficiently. The whole set of accessories with roll film can be easily assembled and disassembled. Even people who have never used the system can easily and effectively replace it correctly. The winding film system can be prefabricated to meet quality standards without waste or damage; like Figure 5 As shown, the inner side of the inner tube 9 is concavely provided with a tube opening for the roll film 6 to pass through, the inner side of the mounting seat 3 is convexly provided with a sliding step 18 matching the tube opening step surface, and the outer end of the mounting seat 3 is concavely provided with a film strip warehouse opening 19 for the roll film 6 to pass through. Considering the smoothness of the left and right ends of the roll film passing through the mirror surface of the goggles when rewinding and replacing the new roll film 6, the single-sided tube opening formed by the inner tube 9 is provided for the roll film to pass through, and cooperates with the internally protruding sliding step 18 to raise the height of the end of the roll film 6 to move outward, so that the roll film 6 can slide out of the film strip warehouse opening 19 from the step surface of the sliding step 18 at the minimum inner angle, ensuring the smoothness of the roll films 6 at both ends when passing through the mounting seat 3, and ensuring the stability of the rewinding activity of the rewinding shaft 13; like Figure 6As shown, the end of the film roll 6, the slide step 18 and the film strip opening 19 are an angular intersection structure with an arch surface, and the film strip opening 19 is slightly higher than the step surface of the slide step 18. The port angle of the film strip opening 19 matches the starting angle of the curved surface of the main frame 1, so that when the film roll 6 is reeled in and replaced with a new one, the end of the film roll 6 entering and exiting the film strip opening 19 can effectively fit with the curved surface of the main frame 1 and the curvature of the goggles, thereby reducing the gap and ensuring the smoothness of the lateral movement of the film roll 6 on the goggles.

[0021] A slide buckle strip 7 is inserted into the inner side of the mounting seat 3, and an inverted flange that can only be locked by longitudinal buckling is formed on the inner edge of the slide buckle strip 7, and a buckling portion matching the slide buckle strip 7 is formed at the relative position of the film roll bin 8, and an axially limited limiting shaft 22 is passed through the slide buckle strip 7 and the mounting seat 3, and a slot for longitudinal sliding adjustment of the limiting shaft 22 is slotted on the mounting seat 3, and the slot has two limiting heights, and the slide buckle strip 7 is opened and closed with the buckling portion of the film roll bin 8 by changing the up and down sliding position of the limiting shaft 22; like Figure 8 As shown, in the film rolling system, the buckling action of the main frame 1 and the mounting seat 3 is further locked by the sliding buckle strip 7 provided on the mounting seat 3, and the sliding buckle strip 7 is axially limited with the card slot on the mounting seat 3 through the limiting shaft 22, and the card slot is provided with two buckling points for the sliding buckle strip 7 to move up and down, and the main frame 1 is mainly completed by the covering action to complete the buckling and fixing of the buckling part with the mounting seat 3, and the undercut flange formed on the inner edge of the sliding buckle strip 7 will limit the corresponding position of the main frame 1 to cover the mounting seat 3 in the initial position. On the seat 3, it is necessary to press the protruding end of one end of the sliding buckle bar 7 to move the limit shaft 22 to the buckle point of the slot, and then make the inverted flanges at both ends of the sliding buckle bar 7 misaligned with the corresponding positions of the main frame 1, so that the main frame 1 can be buckled on the mounting seat 3, and finally, reset the limit shaft 22 by pressing the protruding end of the other end of the sliding buckle bar 7, so that the inverted flanges at both ends of the sliding buckle bar 7 are embedded in the main frame 1, and the main frame 1 and the mounting seat 3 are locked. This structure is used to further strengthen the assembly strength of the roll film system.

[0022] In the film winding system, the pull handle 5 outside the wire drum 4 is manually operated to exert an outward traction force on the pull handle 5 and the wire rope, and the wire rope is wound outside the clockwork mechanism, and the winding shaft 13 is driven to rotate by axial stretching, and then the winding shaft 13 on one side is axially rotated to pull the film 6 on the other side into it; Specifically, the clockwork mechanism includes a toothed disc 14, a clockwork roller 15 and a scroll spring 16. The clockwork roller 15 is fixed to the wire drum 4. The toothed disc 14 is rotatably arranged on the clockwork roller 15. The scroll spring 16 is embedded between the toothed disc 14 and the clockwork roller 15. The head end of the scroll spring 16 is clamped with the clockwork roller 15, and the tail end is tied and fixed with the wire rope of the pull handle 5. The inner edge of the toothed disc 14 is concave with inner teeth, and the stretching direction of the tail end of the scroll spring 16 is relatively distributed with the inner teeth direction of the toothed disc 14. On the basis of the above, as Figure 4 , 10 As shown, the wire rope is mainly pulled out by the outward pulling action of the pull handle 5. Since the wire rope is coiled outside the spiral spring 16, the wire rope will synchronously pull the spiral spring 16 to expand outward along the spring roller 15, and since the inner teeth of the toothed disc 14 are opposite to the tail end of the spiral spring 16, the curling activity of the spiral spring 16 will synchronously utilize the engagement between its tail end and the inner teeth to synchronously drive the toothed disc 14 to rotate relative to the spring roller 15, thereby realizing the transmission with the winding shaft 13. Conversely, after the pull handle 5 is released, the wire rope and the pull handle 5 are reset by the resilience of the spiral spring 16, and due to the spiral The reset direction of the spring 16 is consistent with the inner tooth direction of the toothed disc 14. The reset of the spiral spring 16 will not brake and change the toothed disc 14, that is, it will not drive the reel 13 to rotate in the opposite direction, so that the user can repeatedly pull the pull handle 5, release the pull handle 5 to reset it, and pull the pull handle 5 to rewind the reel 13 and the film 6. The entire operation method is simple and efficient, and the movable structure is stable. Compared with the traditional tearing and replacing film method, the gripping and pulling of the pull handle 5 is easier to wear gloves for immediate film replacement operation, which improves the practicality and operation convenience of the film rolling system. like Figure 5 , 6 As shown in Figures 7 and 8, the connecting end of the tube warehouse 2 and the wire drum 4 is provided with an integrally formed bearing disk 17, the toothed disk 14 is rotatably matched with the bearing disk 17, and the toothed disk 14 extends to the inner end of the bearing disk 17 with a shaft connection opening 20, and the winding shaft 13 extends to the end of the bearing disk 17 with a type of gear shaft 21, and the type of gear shaft 21 is engaged with the shaft connection opening 20. The winding shaft 13 is driven and matched with the toothed disk 14 through the type of gear shaft 21. In order to facilitate the replacement and use of the winding shaft 13 and the roll film 6, the transmission of the winding shaft 13 and its wire drum 4 is The connection structure can realize the snap-fitting and plug-in action with the winding shaft 13. After the end of the winding shaft 13 is snap-fitted and assembled with the tube bin 2, its transmission connection end is mainly connected with the shaft connection port 20 on the bearing plate 17 through a type of gear shaft 21 extending from the outer end, that is, when the pull handle 5 operates the gear plate 14 to rotate, the gear plate 14 rotates axially between the spring roller 15 and the bearing plate 17, and the shaft connection port 20 and the type of gear shaft 21 are connected to realize the transmission of the gear plate 14 and the winding shaft 13; On the basis of the above, a seesaw 11 is axially arranged at one end of the winding shaft 13 relative to a type of gear shaft 21, and one end of the seesaw 11 is in abutment with the winding shaft 13. A limit bin 12 plugged with the seesaw 11 is formed in the film winding bin 8, and a spring member is filled between the limit bin 12 and the seesaw 11. A step surface is formed between the bearing disk 17 and the shaft connecting port 20, and the edges of the type of gear shaft 21 and the shaft connecting port 20 are chamfered. Considering the assembly action of the assembly tube bin 2 and the main frame 1, a seesaw 11 is arranged at the assembly end of the winding shaft 13 relative to the type of gear shaft 21 and the shaft connecting port 20, and the seesaw 11 is subjected to the elastic top force of the spring member in the limited bin 12, so that under normal conditions, the winding shaft 13 will continue to be affected by the pressing action of the seesaw 11. That is, in the process of snapping together and assembling the tube warehouse 2 and the main frame 1, the type-one gear shaft 21 at the other end of the winding shaft 13 will move along the surface of the bearing disk 17 to the step surface of the shaft connecting port 20 as the snapping action deepens, and use the step surface height outside the shaft connecting port 20 to lift up the winding shaft 13 to compress the seesaw 11 and the spring member at the other end. After the type-one gear shaft 21 slides into the axial position of the shaft connecting port 20, the seesaw 11 will cooperate with the rebound of the elastic member to quickly push the type-one gear shaft 21 into the shaft connecting port 20, thereby ensuring the reliability of the transmission structure connection between the shaft connecting port 20 and the type-one gear shaft 21 before and after installation. At the same time, the type-one gear shaft 21 and the shaft connecting port 20 that have been chamfered can be laterally separated from the type-one gear shaft 21 and the shaft connecting port 20 during disassembly.
