Description

Technical Field

[0001] This application relates to the field of welding equipment technology, and in particular to a windproof device. Background Technology

[0002] With the rapid development of China's railway industry and the continuous increase in heavy-haul freight volume, the pressure to prevent railway line breakage in mountainous areas has increased. Gas pressure welding is an important maintenance method for restoring seamless tracks on heavy-haul railways in mountainous areas, and ensuring the safety and improving the quality of gas pressure welding is crucial. During gas pressure welding operations, wind can change the position of the heating torch flame. Therefore, in windy weather, direct wind should be avoided during preheating, welding, and normalizing of the area to be welded to prevent a decline in welding quality or even welding defects. However, currently available welding windproof devices are complex in structure and time-consuming and labor-intensive to install and disassemble, seriously affecting welding efficiency. Utility Model Content

[0003] Therefore, it is necessary to provide a windproof device that is easy to install and remove to address the aforementioned technical problems.

[0004] An embodiment of the first aspect of this application provides a windproof device, including a windproof mechanism and a connector. The number of windproof mechanisms is two. Each windproof mechanism includes a receiving tube, a windproof curtain, and a roller. The receiving tube is hollow to form a receiving cavity. The receiving tube has an opening communicating with the receiving cavity. The roller is located in the receiving cavity and is rotatably connected to the receiving tube. One end of the windproof curtain is wound around the roller and connected to the roller, and the other end extends out of the receiving cavity from the opening. The connector detachably connects the two windproof mechanisms. When the connector is connected to the two windproof mechanisms, the extending directions of the receiving tubes in the two windproof mechanisms intersect.

[0005] In one embodiment, the connector includes a substrate and a first limiting opening and a second limiting opening located on the substrate. The first limiting opening penetrates the substrate along a first direction, and the second limiting opening penetrates the substrate along a second direction. The first direction and the second direction are intersecting. When two windproof mechanisms are connected to the connector, the receiving tube in one windproof mechanism is at least partially located within the first limiting opening and is limited by the side wall of the first limiting opening, and the receiving tube in the other windproof mechanism is at least partially located within the second limiting opening and is limited by the side wall of the second limiting opening.

[0006] In one embodiment, when at least a portion of the receiving tube is located within the first limiting opening and is limited by the side wall of the first limiting opening, the extending direction of the receiving tube is parallel to the first direction; when at least a portion of the receiving tube is located within the second limiting opening and is limited by the side wall of the second limiting opening, the extending direction of the receiving tube is parallel to the second direction.

[0007] In one embodiment, the first direction is parallel to the thickness direction of the substrate, and the second direction intersects the thickness direction of the substrate.

[0008] In one embodiment, the substrate includes a first segment and a second segment connected to each other, a first limiting opening is located in the first segment, a second limiting opening is located in the second segment, and the thickness direction of the first segment intersects the thickness direction of the second segment.

[0009] In one embodiment, a first limiting opening is formed by enclosing a portion of the substrate, and the first limiting opening is configured as a notch recessed inward from the contour edge of the substrate; a second limiting opening is formed by enclosing a portion of the substrate, and the second limiting opening is configured as a notch recessed inward from the contour edge of the substrate.

[0010] In one embodiment, the windproof mechanism further includes a magnetic element disposed on the windproof curtain.

[0011] In one embodiment, the windproof curtain is rectangular in shape and is wound on a roller along its length. Multiple magnetic components are spaced apart on the windproof curtain along its length to form a magnetic assembly. Each windproof curtain is provided with two sets of magnetic assemblies spaced apart along its width.

[0012] In one embodiment, the windproof mechanism further includes a winding member that connects the windproof curtain and the roller, and the winding member applies a force to the windproof curtain as it is wound around the roller.

[0013] In one embodiment, the windproof mechanism also includes a hook that is connected to the receiving tube.

[0014] The windproof device provided in this application, by setting up a windproof mechanism including a receiving tube, a windproof curtain, and a roller, allows the windproof curtain to be pulled out from an opening in the receiving tube to shield the welding position, improving welding quality and efficiency. The windproof curtain can also be rolled up on the roller to reduce its volume, facilitating the transport of the windproof mechanism and thus improving its convenience. By connecting two windproof mechanisms with a connector, and with the two receiving tubes intersecting when connected, a V-shaped structure is formed between the two windproof curtains, improving the windproof performance of the device and further enhancing welding quality and efficiency. By including a connector and two windproof mechanisms, the device has a simple structure, is easy to assemble and disassemble, and allows users to quickly change the welding environment by extending and retracting the windproof curtain, further improving the convenience of the windproof device.

[0029] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0030] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0031] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0032] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0033] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0034] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0035] The windproof device and endoscope provided in the embodiments of this application will be described below with reference to the accompanying drawings. It should be noted that the x-direction in the drawings is the first direction, and the y-direction is the second direction. In the drawings, for ease of drawing, the dimensions are not necessarily proportional to the actual dimensions.

[0036] Please refer to Figures 1 to 3 , Figure 1 This is a schematic diagram of the structure of a windproof device according to some embodiments of this application. Figure 2 A schematic diagram of an example windproof mechanism is shown. Figure 3 A schematic diagram of an example connector is shown.

[0037] like Figures 1 to 3 As shown, this application provides a windproof device, including a windproof mechanism 10 and a connector 20. There are two windproof mechanisms 10, each including a receiving tube 100, a windproof curtain 200, and a roller (not shown). The receiving tube 100 is hollow, forming a receiving cavity (not shown). The receiving tube 100 has an opening (not shown) communicating with the receiving cavity. The roller is located inside the receiving cavity and rotatably connected to the receiving tube 100. One end of the windproof curtain 200 is wound around the roller and connected to it, while the other end extends out of the receiving cavity from the opening. The connector 20 detachably connects the two windproof mechanisms 10. When the connector 20 is connected to both windproof mechanisms 10, the extending directions of the receiving tubes 100 in the two windproof mechanisms 10 intersect.

[0038] The windproof curtain 200 can be made of windproof cloth, flexible metal film, or polymer material, etc.

[0039] It should be noted that the extension direction of the receiving tube 100 refers to its axial direction. When the windproof curtain 200 is pulled out of the receiving cavity by an external force, the pulling direction intersects with the extension direction of the receiving tube 100. When the connector 20 is connected to the two windproof mechanisms 10, the included angle between the extension directions of the receiving tubes 100 in the two windproof mechanisms 10 can be an acute angle, a right angle, or an obtuse angle. The two windproof curtains 200 extending from the openings of the two receiving tubes 100 form a V-shaped structure. While improving the windproof performance of the windproof device, the sharp corner of the V-shaped structure formed between the two windproof curtains 200 serves as the windward surface, reducing the wind resistance of the windproof device and thus improving the stability of the windproof device in windy weather.

[0040] It's easy to understand that during welding and preheating, it's necessary to ensure the welding position is protected from wind. However, after welding, when performing air-cooling normalizing on the welded area, it's necessary to increase the airflow velocity at the welding position to maintain the cooling rate of the welding material within a suitable range. The windproof mechanism of this application, through the inclusion of a receiving tube, a windproof curtain 200, and a roller, allows the user to pull the windproof curtain 200 out of the opening in the receiving tube 100 during preheating and welding to shield the welding position, improving welding quality and efficiency. When normalizing is required after welding, the user can roll the windproof curtain 200 onto the roller to expose the welding position, increasing the airflow velocity at that location. When changing welding sites, the user simply removes the connector 20 and rolls the windproof curtain 200 onto the roller, reducing the size of the windproof device and facilitating its transport, thus improving its convenience.

[0041] The windproof device of this embodiment includes a windproof mechanism 10, comprising a receiving tube 100, a windproof curtain 200, and a roller. The windproof curtain 200 can be pulled out from the opening in the receiving tube 100 to shield the welding position, improving welding quality and efficiency. The windproof curtain 200 can also be wound onto the roller to reduce its size, facilitating the transport of the windproof mechanism 10 and improving its convenience. Two windproof mechanisms 10 are connected by a connector 20, and when connected, the extension directions of the two receiving tubes 100 intersect, forming a V-shaped structure between the two windproof curtains 200. This improves the windproof performance of the device, further enhancing welding quality and efficiency. By including the connector 20 and two windproof mechanisms 10, the windproof device has a simple structure, is easy to assemble and disassemble, and allows users to quickly change the welding environment by extending and retracting the windproof curtain 200, further improving its convenience.

[0042] Please refer to Figures 3 to 5 , Figure 4 A partial top view schematic diagram of an example windproof device is shown. Figure 5 A partial top view of another example of a windproof device is shown.

[0043] like Figures 3 to 5 As shown, in some embodiments, the connector 20 includes a substrate 21 and a first limiting opening 201 and a second limiting opening 202 located on the substrate 21. The first limiting opening 201 extends through the substrate 21 along a first direction (x direction in the figure), and the second limiting opening 202 extends through the substrate 21 along a second direction (y direction in the figure). The first direction x and the second direction y intersect. When two windproof mechanisms 10 are connected to the connector 20, the receiving tube 100 in one windproof mechanism is at least partially located within the first limiting opening 201 and is limited by the side wall of the first limiting opening 201, while the receiving tube 100 in the other windproof mechanism 10 is at least partially located within the second limiting opening 202 and is limited by the side wall of the second limiting opening 202.

[0044] The shapes and dimensions of the first limiting opening 201 and the second limiting opening 202 correspond to the cross-sectional shape and dimensions of the receiving tube 100, allowing the receiving tube 100 to be confined within the first limiting opening 201 and the second limiting opening 202. In this embodiment, the cross-sectional shape of the receiving tube 100 is a circular tube, and the shapes of the first limiting opening 201 and the second limiting opening 202 are approximately circular, as an example for illustration.

[0045] When at least a portion of the receiving tube 100 is located within the first limiting opening 201 and is limited by the side wall of the first limiting opening 201, the extending direction of the receiving tube 100 is parallel to the first direction x. When at least a portion of the receiving tube 100 is located within the second limiting opening 202 and is limited by the side wall of the second limiting opening 202, the extending direction of the receiving tube 100 is parallel to the second direction y. This results in the extending directions of the two receiving tubes 100 in the two windproof mechanisms 10 connected by the connector 20 intersecting, thus forming a V-shaped structure between the two windproof curtains 200.

[0046] The windproof device of this application embodiment uses a first limiting opening 201 and a second limiting opening 202 on the substrate 21 to fix the receiving tube 100, thereby realizing the function of the connector 20 connecting the two windproof mechanisms 10.

[0047] like Figure 4 As shown, in some embodiments, the first direction x is parallel to the thickness direction of the substrate 21, and the second direction y intersects the thickness direction of the substrate 21.

[0048] In this embodiment, the substrate 21 is a flat plate. The first limiting opening 201 penetrates the substrate 21 along the thickness direction of the flat plate, while the second limiting opening 202 penetrates the substrate 21 along the direction of the thickness direction of the inclined flat plate, so that the axes of the first limiting opening 201 and the second limiting opening 202 intersect, thereby realizing that the extension directions of the two receiving tubes 100 in the two windproof mechanisms 10 connected by the connector 20 intersect, so that a V-shaped structure is formed between the two windproof curtains 200.

[0049] Of course, in other embodiments, the first limiting opening 201 and the second limiting opening 202 both penetrate the substrate 21 along the thickness direction of the inclined substrate 21, except that the axes of the first limiting opening 201 and the second limiting opening 202 also intersect.

[0050] like Figure 5 As shown, in some embodiments, the substrate 21 includes a first segment 203 and a second segment 204 that are connected to each other. A first limiting opening 201 is located in the first segment 203, and a second limiting opening 202 is located in the second segment 204. The thickness direction of the first segment 203 intersects the thickness direction of the second segment 204.

[0051] Optionally, when the connector 20 connects two windproof mechanisms 10, the thickness direction of the first segment 203 is parallel to the first direction x, and the thickness direction of the second segment 204 is parallel to the second direction y.

[0052] The windproof device of this application embodiment makes the base plate 21 a V-shaped plate, with the first limiting opening 201 and the second limiting opening 202 located on the two sections of the V-shaped plate, so that when the connector 20 connects the two windproof mechanisms 10, the extension directions of the two receiving tubes 100 in the two windproof mechanisms 10 intersect, so that a V-shaped structure is formed between the two windproof curtains 200.

[0053] In some embodiments, a first limiting opening 201 is partially enclosed by a substrate 21, and the first limiting opening 201 is configured as a notch recessed inward from the contour edge of the substrate 21. A second limiting opening 202 is partially enclosed by a substrate 21, and the second limiting opening 202 is configured as a notch recessed inward from the contour edge of the substrate 21.

[0054] Wherein, when the first limiting opening 201 and the second limiting opening 202 are in the receiving tube 100, the notches on the first limiting opening 201 and the second limiting opening 202 are used to allow the windproof curtain 200 to be smoothly pulled out or retracted from the opening on the receiving tube 100 without being obstructed by the side walls of the first limiting opening 201 and the second limiting opening 202.

[0055] Optionally, the substrate 21 may be made of materials such as metals, metal oxides, or polymers. The substrate 21 possesses a certain degree of elasticity, allowing the first limiting opening 201 to expand when subjected to external force, facilitating the entry of the receiving tube 100 into the first limiting opening 201. After the receiving tube 100 enters the first limiting opening 201, the substrate 21 rebounds under the influence of elastic potential energy, and the notch of the first limiting opening 201 returns to its initial size, thus limiting the receiving tube 100 to the sidewall of the first limiting opening 201. The second limiting opening 202 operates similarly and will not be described further here.

[0056] like Figure 2 As shown, in some embodiments, the windproof mechanism 10 further includes a magnetic suction element 300, which is disposed on the windproof curtain 200.

[0057] Optionally, the windproof curtain 200 is rectangular in shape and is wound on a roller along its length. Multiple magnetic components 300 are spaced apart along the length of the windproof curtain 200 to form magnetic assemblies. Each windproof curtain 200 has two sets of magnetic assemblies spaced apart along its width. This can be understood as the two sets of magnetic assemblies being arranged along the long side of the windproof curtain 200. When the connector 20 connects the two windproof mechanisms 10, the magnetic assemblies on the two windproof curtains 200 that are close to each other can be magnetically connected, forming a V-shaped structure. This improves the stability of the windproof device and reduces the probability of strong winds blowing from the sharp corner of the V-shaped structure to the welding position, reducing air leakage and further improving the windproof capability of the device. Furthermore, when the windproof device is used for welding in locations such as railway tracks, the user can use the magnetic attachment 300 on the side of the windproof curtain 200 away from the receiving tube 100 to fix the side of the windproof curtain 200 away from the receiving tube 100 to the railway track, thereby ensuring the stability of the windproof curtain 200. Of course, the windproof device can also produce the same technical effect when used for welding in other locations where metal is arranged.

[0058] In other embodiments, the magnetic element 300 may also be two magnetic strips located on the long side of the windproof curtain 200.

[0059] In some embodiments, the windproof mechanism 10 further includes a winding member (not shown) that connects the windproof curtain 200 and the roller, and the winding member applies a force to the windproof curtain 200 as it is wound around the roller.

[0060] The winding component can be a torsion spring, which uses a principle similar to a measuring tape to enable the windproof curtain 200 to automatically wind onto the roller when there is no external force, further improving the convenience of the windproof device.

[0061] In some embodiments, the windproof mechanism 10 also includes a hook 400 connected to the receiving tube 100.

[0062] Optionally, the hook 400 is located outside the receiving cavity, and the opening on the hook 400 and the receiving tube 100 are located on different sides of the receiving tube 100. The user can conveniently suspend both windproof mechanisms 10 above the welding position using the hook 400, and then connect the two receiving tubes 100 at a suitable angle using the connector 20. Afterwards, pull down the two windproof curtains 200 and connect their adjacent long sides using the magnetic 300. After welding or preheating, pulling down the windproof curtains 200 will automatically retract and wind them onto the reel under the action of the winding component, exposing the welding position. Finally, to remove the windproof device, simply remove the connector 20 and detach the hook 400 to conveniently pack and transport the connector 20 and the two windproof mechanisms 10.

[0063] Of course, a hook can also be provided on the short side of the windproof curtain 200 away from the roller to fix the windproof curtain 200 after it is pulled open. This is suitable for welding scenarios where there is no suitable metal material as a fixing base for the magnetic part 300.

[0064] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this application.

[0065] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this application should be determined by the appended claims.
