Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of industrial protective tools, in particular to a foldable funnel. Background Art
[0002] Electric welding is a common construction operation that can quickly connect two materials together. When welding, sufficient solder must be present to ensure weld quality and avoid cold joints. Excess solder will form slag.
[0003] Welding slag can reach temperatures exceeding 1000°C. The slag splashed during welding can easily ignite surrounding combustibles, leading to fire accidents. Therefore, flammable and combustible materials must be kept away from welding areas, and fire extinguishers must be available.
[0004] However, welding operations must sometimes be performed in production workshops, where slag splashing onto equipment can easily damage it. To prevent disruptions to production, equipment cannot be moved during welding, nor can fire blankets or panels be used to cover the equipment. Therefore, a detachable, readily removable slag prevention tool is needed that does not affect equipment operation. Utility Model Content
[0005] The utility model aims at the deficiencies in the prior art and provides a foldable funnel, which can prevent welding slag from falling onto equipment during electric welding in a workshop.
[0006] In order to solve the above technical problems, the present invention is solved by the following technical solutions:
[0007] A foldable funnel comprising
[0008] A plurality of fireproof panels, wherein two adjacent fireproof panels are rotatably connected so as to be rotatably overlapped; and
[0009] The connecting device includes a first unit and a second unit that cooperate with each other. The first unit and the second unit are respectively arranged on the two outermost fireproof boards. When all the fireproof boards are unfolded and the first unit is cooperated and connected with the second unit, a funnel-shaped main body is formed.
[0010] In the above solution, preferably, the hypotenuses of all the fireproof boards are equal.
[0011] In the above solution, preferably, all the fireproof panels are trapezoidal in shape, so as to form a discharge port for discharging waste in the middle when they are unfolded.
[0012] In the above solution, preferably, a fireproof cloth is provided on the upper surface and / or lower surface of the fireproof board.
[0013] In the above solution, preferably, a hole is opened at the bottom corner of the outer end of the fireproof board, and when two adjacent fireproof boards are rotated and superimposed, the two holes at least partially overlap.
[0014] In the above solution, preferably, the first unit is a hook fixed on the fireproof board, and the second unit is a through hole opened on the fireproof board.
[0015] In the above solution, preferably, the first unit and the second unit are two magnet blocks that are magnetically attracted to each other.
[0016] In the above solution, preferably, the first unit and the second unit are snap fasteners.
[0017] The beneficial effects of the utility model are:
[0018] After unfolding, the utility model is placed under the welding place to prevent welding slag from falling onto the equipment during electric welding, and the welding slag and other garbage can be collected by falling through the central discharge port of the device; the fireproof board can be folded together by cross-folding forward and backward, which is convenient for storage and transportation;
[0019] The holes on the fireproof board can be matched with the hooks to position the funnel when unfolded. When folded, all the fireproof boards can be limited by the rope for storage. At the same time, the rope can also serve as a carrying handle.
[0020] Fireproof cloth is set on the upper and lower surfaces of the fireproof board to extend the service life of the funnel and improve its aesthetics. BRIEF DESCRIPTION OF THE DRAWINGS
[0021] Figure 1 This is a schematic diagram of the utility model in the unfolded assembly state.
[0022] Figure 2 This is a schematic diagram of the utility model in the expanded and separated state.
[0023] Figure 3 This is a schematic diagram of the utility model in a folded state. DETAILED DESCRIPTION
[0024] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments:
[0025] See also Figure 1-Figure 3 A foldable funnel includes several fireproof panels 1 and a connecting device. The fireproof panels 1 are arranged in sequence. Two adjacent fireproof panels 1 are rotated and connected. The connection can be flipped 180 degrees so that the two can be rotated and overlapped.
[0026] In this embodiment, the fireproof board 1 has equal hypotenuses and a trapezoidal shape. Figure 1 、 Figure 2As shown, after it is unfolded, the upper ends of all the fireproof panels 1 are surrounded to form a discharge port 2 for discharging waste, which is also the middle position of the funnel formed by the unfolded fireproof panels.
[0027] The fireproof board 1 is made of non-combustible material, and welding slag falling onto the fireproof board 1 will not cause combustion. In order to further enhance the fireproof effect, extend the service life of the funnel, and improve the aesthetics, in this embodiment, a fireproof cloth is provided on the upper surface and / or lower surface of the fireproof board 1, and the fireproof cloth can be fixed to the fireproof board by glue, nails, etc.
[0028] As for the connecting device, it includes a first unit 31 and a second unit 32 that cooperate with each other, wherein, in the component composed of the above-mentioned fireproof board 1, the two fireproof boards 1 at the outermost ends have only one oblique edge that is rotatably connected to the other fireproof boards 1, and the other oblique edge is used to set the connecting device, such as Figure 2 As shown, a first unit 31 is provided on one of the two fireproof panels 1 at the outermost end, and a second unit 32 is provided on the other. The two fireproof panels 1 at the outermost end are connected together by connecting and cooperating with the first unit 31 and the second unit 32. Figure 1 As shown, this is the funnel in use.
[0029] The specific structures of the first unit 31 and the second unit 32 can be in various forms, including:
[0030] First, the first unit 31 is a hook fixed to the fireproof board 1, and the second unit 32 is a through hole opened in the fireproof board 1. The two fireproof boards are connected by hanging the hook on the through hole. Furthermore, the hook can be a spring hook, which has a spring and a hook portion, the inner end of the hook portion is connected to one end of the spring, and the other end of the spring is fixed to the fireproof board, or a connecting block is fixed to the fireproof board, and the other end of the spring is fixed to the connecting block.
[0031] Secondly, the first unit and the second unit are both magnet blocks, and are two magnet blocks that are magnetically attracted to each other, and the two fireproof panels are connected by magnetic attraction.
[0032] Third, the first unit and the second unit are snap fasteners, which connect the two fireproof panels by buckling them together.
[0033] In this embodiment, a hole 11 is opened at the bottom corner of the outer end of the fireproof board 1. When two adjacent fireproof boards 1 are rotated and overlapped, the two holes 11 are aligned.
[0034] When in use, a hook can be set on the hole 11 on the fireproof board 1, and the funnel can be hung below the welding point. An iron bucket can be placed at the bottom of the funnel (below the discharge port 2) to collect garbage such as solder, used welding rods, and rust.
[0035] After use, the connecting device at the edge of the fireproof board 1 is removed so that the funnel can be unfolded and laid flat on a flat surface, and then the fireproof board 1 is folded together by folding forward and backward for easy storage and transportation.
[0036] After folding, the holes 11 at the bottom corners of the long sides of the fireproof board 1 are aligned, and a rope 4 can be passed through these holes 11 to achieve storage. At the same time, the rope 4 can serve as a carrying handle (the rope ends are knotted). At this time, the connecting devices can also be connected to improve the storage effect.
