Description

Technical Field

[0001] This utility model relates to the field of sun hat technology, and in particular to a sun hat with a heat dissipation channel. Background Technology

[0002] A hat is a garment worn on the head, usually covering the entire top of the head. Hats are primarily used to protect the head, and some have protruding brims to block sunlight. Hats serve multiple purposes, including sun protection, decoration, warmth, and protection, and therefore come in many varieties, requiring careful selection. Sun hats are summer hats used for sun protection. They are commonly made of cloth, straw, or plastic. Sun hats provide protection from wind on cloudy days and from the sun on sunny days, making them an indispensable daily item for men, women, and children of all ages. According to patent document CN221044341U, a sun hat designed to prevent it from being blown off by the wind is disclosed. The hat includes a sun hat body, a brim movably mounted on one side of the body, fans symmetrically mounted inside the brim, a first fixing block fixedly mounted on one side of the body, and a second fixing block fixedly mounted on one side of the first fixing block and located on the same side of the body. The first fixing block, the second fixing block, and the brim are rotatably connected. An adjustment component is provided inside the second fixing block. A fixing buckle is fixedly mounted on one side of the body, and an adjustment strap is movably mounted inside the buckle. The adjustment strap is fixedly connected to the other side of the body.

[0003] Currently, traditional sun hats with ventilation channels are simple in structure and have limited function. As times change and people's functional needs for hats increase, common sun hats lack eye protection, which can cause significant damage to the eyes when the sun is strong. They also only provide sun protection for the face, leaving the neck area unprotected from the sun. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned problems by providing a sun hat with a heat dissipation channel.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A sun hat with a heat dissipation channel includes a hat top; ventilation grooves are provided on both sides of the upper end of the hat top, a brim is provided at the front end of the hat top, side plates are fixedly connected to both sides of the lower end of the brim, a disassembly and assembly mechanism is detachably connected to the side of the two side plates that are close to each other, a fixing plate is fixedly connected to both bottom sides of the hat top, an installation hole is opened at the upper end of the fixing plate, a sunshade mechanism is fixedly connected to the lower end of the fixing plate, the disassembly and assembly mechanism includes a fixing shell, one side of the fixing shell is fixedly connected to one side of the side plate, a slot is provided on the inner wall of the fixing shell, a limit groove is provided on both sides of the inner wall of the slot, a rod is inserted into the inner wall of the slot, an end cap is bolted to the upper end of the rod, a spring is fixedly connected to one side of the inner wall of the rod, a limit block is fixedly connected to the other side of the spring, a connecting plate is fixedly connected to the lower end of the rod, a rotating rod is fixedly connected to one side of the connecting plate, and a sun protection glasses are rotatably connected to one end of the rotating rod.

[0006] The beneficial effects of this utility model are as follows: Ventilation slots for air circulation are provided on both sides of the upper part of the hat top to ensure effective heat dissipation for the head. Simultaneously, a brim for sun protection is provided at the front of the hat top. Side panels are securely connected to both sides of the lower end of the brim. These two side panels are detachably connected on their adjacent sides by a disassembly mechanism, allowing the user to easily adjust or disassemble them as needed. Furthermore, fixing plates are securely connected to the bottom of both sides of the hat top. These fixing plates have mounting holes at their upper ends for connecting mounting bases, while their lower ends are securely connected to a sunshade mechanism to enhance the sunshade effect. [Further details about the fixing plate and side panels are needed for accurate translation.] The connection is robust. The inner wall of the fixed shell has a slot, and the inner wall of the slot also has limit grooves on both sides to ensure the stability of the plug-in components. A plug rod is inserted into the inner wall of the slot. The upper end of the plug rod is connected to an end cap by bolting. A spring is firmly connected to one side of the inner wall of the plug rod, and a limit block is firmly connected to the other side of the spring to control the extension and retraction of the plug rod. The lower end of the plug rod is firmly connected to a connecting plate, and a rotating rod is firmly connected to one side of the connecting plate. A pair of sun protection glasses is connected to one end of the rotating rod by a rotating connection. Users can flexibly rotate and use the sun protection glasses as needed, thereby achieving a multi-functional sun protection and heat dissipation effect.

[0007] 1. This utility model, through its disassembly and assembly mechanism, allows the device to flexibly adjust the installation and disassembly of sun protection glasses according to different usage scenarios and user needs. When sun protection glasses are needed for eye protection, the user only needs to insert the plug into the slot inside the fixed shell. The limiting block is locked into the limiting groove under the action of the spring, which can achieve quick installation. When sun protection glasses are not needed, the user can press the end cover to make the limiting block disengage from the limiting groove, and then pull the plug out of the slot to complete the disassembly. This detachable setting not only improves the practicality of the sun hat, but also meets the personalized needs in a variety of scenarios. 2. This utility model, through its sunshade mechanism, allows the device to flexibly adjust the installation and angle of the sunshade cloth according to different ambient light conditions and user needs. When enhanced sunshade effect is required, the sunshade cloth can be inserted into the mounting slot of the mounting base and secured with bolts through the through holes and nuts to ensure the sunshade cloth is stable and does not fall off. When reduced sunshade area or ventilation is required, the nuts can be loosened to adjust the angle of the sunshade cloth or completely disassemble it. This flexible sunshade mechanism not only improves the applicability of the sun hat but also effectively protects the user's face and neck from ultraviolet radiation, further enhancing the product's protective performance.

[0008] Furthermore, the inner wall of the fixed shell is embedded and connected to the outer wall of the slot, and the two sides of the inner wall of the slot are embedded and connected to one side of the limiting groove.

[0009] The beneficial effects of the above-mentioned further solution are: the inner wall of the fixed housing and the outer wall of the slot are tightly connected by an embedded connection, ensuring the stability and consistency between the two. At the same time, the two sides of the inner wall of the slot and one side of the limiting groove are also connected by an embedded connection. This setting not only enhances the stability of the overall structure, but also effectively limits the movement range of objects in the slot during use, thereby improving the safety and reliability of the entire device. Through this structural setting, the close cooperation and efficient operation between various components are ensured.

[0010] Furthermore, the number of limiting grooves is set to five, and their shape is adapted to the limiting block.

[0011] The beneficial effects of the above-mentioned further solution are: the number of limiting slots is carefully set to five. This setting is intended to ensure the stability of the structure and the diversity of functions. At the same time, the shape of these limiting slots is set so that they are perfectly adapted to the limiting blocks, thereby achieving seamless connection during installation and use. This ensures that the limiting blocks can be smoothly embedded in the slots to achieve the expected limiting effect and improve the safety and reliability of the overall device.

[0012] Furthermore, the sunshade mechanism includes a mounting base, the upper end of which is bolted to the lower end of the fixing plate. The mounting base has a mounting groove in the middle of its inner wall, and bolts are provided on both sides of the mounting base. A sunshade cloth is detachably connected to the inner wall of the mounting groove. Through holes are provided on both sides of the upper end of the sunshade cloth, and nuts are threaded to the ends of the bolts.

[0013] The beneficial effects of the above-mentioned further solution are as follows: the upper part of the mounting base is tightly connected to the lower part of the fixing plate by bolting, ensuring the stability of the entire sunshade mechanism. In the internal structure of the mounting base, a mounting groove is set in the middle of its inner wall. This mounting groove plays a crucial role, mainly used for the installation and fixing of subsequent components. In addition, bolts are symmetrically arranged on both sides of the mounting base. These bolts not only serve a fixing function but also facilitate subsequent disassembly and adjustment. A sunshade cloth can be flexibly and detachably connected to the inner wall of the mounting groove. This setting makes the replacement and maintenance of the sunshade cloth extremely convenient. The sunshade cloth has through holes on both sides of its upper end. These through holes correspond to the positions of the bolts, ensuring that the sunshade cloth can be firmly fixed to the mounting base. Finally, the ends of the bolts are connected to nuts by threads. This threaded connection method not only ensures the firmness of the connection but also facilitates fine-tuning in actual use, ensuring that the tension of the sunshade cloth is moderate, thereby achieving the best sunshade effect.

[0014] Furthermore, the inner wall of the mounting base is embedded and connected to the outer wall of the mounting groove, and the two sides of the mounting groove are inserted into the outer wall of the bolt.

[0015] The beneficial effects of the above-mentioned further solution are: the middle part of the inner wall of the mounting base is tightly connected to the outer wall of the mounting groove by embedding, ensuring the stability and consistency between the two. At the same time, the two side edges of the mounting groove are combined with the outer wall surface of the bolt by plugging. This setting not only facilitates installation and disassembly, but also effectively improves the stability and reliability of the overall structure, ensuring that there will be no loosening or falling off during actual use.

[0016] Furthermore, the bolt extends into the nut through the through hole in the mounting base and the sunshade cloth.

[0017] The beneficial effect of the above-mentioned further solution is that the bolt, through a precise installation process, first passes through the set mounting seat, then continues to extend, passes through the pre-set through hole inside the sunshade cloth, and finally precisely reaches and screws into the nut, ensuring the stability and reliability of the entire structure.

[0018] Furthermore, the outer wall of the ventilation slot is connected through to both sides of the upper end of the hat top, and the rear end of the brim is fixedly connected to the front end of the hat top.

[0019] The beneficial effects of the above-mentioned further solution are: the outer wall of the ventilation channel is connected to the upper two sides of the top of the hat in a through-type connection, which ensures the stability and integrity between the ventilation channel and the top of the hat. At the same time, the rear end of the brim is fixed to the front end of the top of the hat in a strong connection method. This connection method not only enhances the bonding strength between the brim and the top of the hat, but also ensures the stability and durability of the overall structure.

[0022] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0023] Example 1 like Figure 1-4As shown, a sun hat with a heat dissipation channel includes a hat top 1; ventilation slots 2 are provided on both sides of the upper end of the hat top 1, a brim 3 is provided at the front end of the hat top 1, and side plates 4 are fixedly connected to both sides of the lower end of the brim 3. A disassembly and assembly mechanism 5 is detachably connected to the side of the two side plates 4 that are close to each other. Fixing plates 6 are fixedly connected to the bottom of both sides of the hat top 1. The upper end of the fixing plate 6 has a mounting hole 7, and the lower end of the fixing plate 6 is fixedly connected to a sunshade mechanism 8. The disassembly and assembly mechanism 5 includes a fixing shell 51, one side of the fixing shell 51 is fixedly connected to one side of the side plate 4, and the inner wall of the fixing shell 51 is... The slot 52 is provided, and the inner wall of the slot 52 is provided with limit grooves 53 on both sides. The inner wall of the slot 52 is inserted into the rod 54, and the upper end of the rod 54 is bolted with an end cap 55. A spring 56 is fixed to one side of the inner wall of the rod 54, and a limit block 57 is fixed to the other side of the spring 56. A connecting plate 58 is fixed to the lower end of the rod 54, and a rotating rod 59 is fixed to one side of the connecting plate 58. A sun protection glasses 510 is rotatably connected to one end of the rotating rod 59. The outer wall of the ventilation slot 2 is connected through to the upper two sides of the top of the hat 1, and the rear end of the brim 3 is fixed to the front end of the top of the hat 1.

[0024] The inner wall of the fixed shell 51 is embedded and connected to the outer wall of the slot 52, and the two sides of the inner wall of the slot 52 are embedded and connected to one side of the limiting groove 53.

[0025] The number of limiting grooves 53 is set to five, and their shape is adapted to the limiting block 57.

[0026] The working principle or usage method of this embodiment is as follows: In actual use, the user first puts the sun hat on their head. The ventilation slots 2 set on both sides of the upper end of the hat top 1 can effectively promote air circulation on the head, achieve good heat dissipation, and avoid the head from feeling stuffy due to wearing the hat for a long time. When encountering strong sunlight, the brim 3 can shade most of the face area and reduce direct sunlight. At the same time, the disassembly and assembly mechanism 5, which is detachably connected to the side plates 4 on both sides of the lower end of the brim 3, plays an important role. The user can adjust or use the sun protection glasses 510 by operating the disassembly and assembly mechanism 5 as needed. The insertion rod 54 moves in the slot 52, the spring 56 is compressed, and the limiting block 57 disengages from the current limiting groove 53. When the insertion rod 54 moves to the appropriate position, the limiting block 57 is embedded in the corresponding limiting groove 53 under the action of the spring 56, realizing the positioning of the insertion rod 54. At this time, the rotation The sun protection glasses 510, which are rotatably connected to one end of the rod 59, can be rotated to a suitable position to provide sun protection for the eyes and effectively prevent sunlight from damaging the eyes. Moreover, when the sun protection glasses 510 are not needed, they can also be stored away by operating the disassembly mechanism 5. In addition, the fixing plates 6 fixed to the bottom of both sides of the hat top 1, and the sunshade mechanism 8 fixed to the lower end of their fixing plates 6, can also provide users with a more comprehensive sunshade effect. The upper end of the mounting base 81 is bolted to the lower end of the fixing plate 6. The mounting groove 82 in the middle of the inner wall of the mounting base 81 is detachably connected to the sunshade cloth 84. Users can install or remove the sunshade cloth 84 according to actual needs. When installing, align the through holes 85 on both sides of the upper end of the sunshade cloth 84 with the bolts 83 on both sides of the mounting base 81, and then use the nuts 86 to firmly fix the sunshade cloth 84 to the mounting base 81. The sunshade cloth 84 can provide sun protection for the neck and other parts of the body, further improving the practicality of the sun hat.

[0027] Example 2 like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a sun hat with a heat dissipation channel includes a sunshade mechanism 8 including a mounting base 81. The upper end of the mounting base 81 is bolted to the lower end of the fixing plate 6. A mounting groove 82 is provided in the middle of the inner wall of the mounting base 81. Bolts 83 are provided on both sides of the mounting base 81. A sunshade cloth 84 is detachably connected to the inner wall of the mounting groove 82. Through holes 85 are opened on both sides of the upper end of the sunshade cloth 84. Nuts 86 are threaded to the ends of the bolts 83.

[0028] The inner wall of the mounting base 81 is embedded and connected to the outer wall of the mounting groove 82, and the two sides of the mounting groove 82 are inserted into the outer wall of the bolt 83.

[0029] Bolt 83 extends through the through hole 85 in the mounting base 81 and the sunshade cloth 84 to the nut 86.

[0030] The working principle or usage method of this embodiment is as follows: First, the user correctly wears the sun hat on their head. The ventilation slots 2 on both sides of the hat top 1 then begin to function, continuously promoting air circulation around the head, keeping the head relatively dry and comfortable while wearing the hat, preventing stuffiness and discomfort from prolonged wear. When in a strong sunlight environment, the brim 3 effectively blocks most of the face, reducing direct sunlight exposure. The fixing plates 6 fixedly connected to the bottom of both sides of the hat top 1, with their lower ends connected to the sunshade mechanism 8, also play a crucial role at this time. The upper end of the mounting base 81 is tightly bolted to the lower end of the fixing plate 6. A sunshade cloth 84 is installed in the mounting groove 82 in the middle of the inner wall of the mounting base 81. Users can decide whether to install the sunshade cloth 84 based on actual sunlight conditions. If installation is required, simply align the through holes 85 on both sides of the upper end of the sunshade cloth 84 with the bolts 83 on both sides of the mounting base 81, then screw the nuts 86 onto the ends of the bolts 83. The sunshade cloth 84 is then securely fixed to the mounting base 81 via threaded connection. Once fixed, the sunshade cloth 84 effectively provides sun protection for the neck and other areas. To prevent sunburn on the neck area, when the sunshade 84 is no longer needed, simply unscrew the nut 86 and remove the sunshade 84. The operation is very convenient. Simultaneously, the disassembly and assembly mechanism 5, where the side panels 4 on both sides of the lower end of the brim 3 are close together, can also be used flexibly. When the sunlight is too strong and the eyes feel irritated, the user lowers the connecting plate 58, the insert 54 moves within the slot 52, the spring 56 is compressed, and the limiting block 57 disengages from the current limiting slot 53. When the insert 54 moves to a position where the sun protection glasses 510 can be used comfortably, the limiting block 57 is engaged with the spring 56. The rod 54 is positioned by embedding itself into the corresponding limiting groove 53. At this time, the sun protection glasses 510 connected to one end of the rotating rod 59 can be rotated to a suitable position to provide good sun protection for the eyes and prevent sunlight from damaging the eyes. When the sun protection glasses 510 are no longer needed, the connecting plate 58 is lowered again to move the rod 54, so that the limiting block 57 is disengaged from the limiting groove 53 and the sun protection glasses 510 can be stored away. Through this structure, the sun hat achieves a multi-functional sun protection and heat dissipation effect, meeting the needs of users in different environments.

[0031] In this embodiment, anti-slip textures can also be provided on the end cap 55, making it easier for the user to apply force when pressing the end cap 55, reducing the risk of slippage and improving the accuracy and convenience of operation. At the same time, the shape and size of the ventilation slot 2 can be varied. The size of the ventilation slot 2 can be adjusted according to different usage scenarios and needs to better achieve air circulation and heat dissipation for the head. In terms of the material selection for the sunshade cloth 84, a lighter, more breathable material with better sun protection can be selected to further improve the performance of the sunshade cloth 84 and make the user more comfortable when wearing the sun hat. In addition, the lenses of the sun protection glasses 510 can be made of lenses with multiple functions such as UV protection and anti-glare to enhance the protection of the eyes and improve the versatility and practicality of the sun hat.
