Description
Technical Field
[0001] The utility model belongs to the technical field of hydropower engineering, and particularly relates to an outer footrest structure of a hot melt machine. Background Art
[0002] A hot melt machine is a professional welding tool used to heat and melt thermoplastic pipes and molds and then connect them. The hot melt machine plays a crucial role in the connection of pipes and fittings. In order to ensure the stability of the hot melt machine during use, the hot melt machine needs to be supported by a footrest.
[0003] In order to facilitate carrying and use, the existing hot melt machines usually have a retractable footrest structure at the bottom of the machine shell. When in use, the footrest can be directly rotated out from the bottom of the machine shell. However, most of the existing footrest structures do not have a fixing device and only rely on their own damping for a certain limit. This setting makes the footrest prone to rotation during the retraction and use of the footrest, resulting in low stability during the retraction and use of the footrest.
[0004] In view of the problems in the related art, no effective solution has been proposed yet. Content of the Utility Model
[0005] In view of the problems in the related art, the utility model provides an outer footrest structure of a hot melt machine to overcome the above technical problems existing in the existing related art.
[0006] To solve the above technical problems, the utility model is realized through the following technical solutions:
[0007] The utility model provides an outer footrest structure of a hot melt machine, which includes a machine shell. A rotating disc is arranged at the bottom of the machine shell. A clamping component is arranged between the bottom of the machine shell and the top of the rotating disc. A footrest is fixedly connected to the bottom of the rotating disc. A fixing component is arranged at the top of the rotating disc corresponding to the clamping end of the clamping component. An elastic pulling component is arranged at the top end of the fixing component. A blocking component is arranged inside the footrest.
[0008] Further, the clamping component includes a fixing bolt fixedly connected to the bottom of the machine shell. A clamping cylinder is fixedly connected to the outer surface of the fixing bolt. A clamping groove is formed at the bottom of the clamping cylinder. A clamping block is clamped inside the clamping groove. The clamping block is fixedly connected to the rotating disc. The rotating disc is rotatably connected to the fixing bolt.
[0009] Further, the clamping component further includes a rotating ring. A rotating groove is formed on the inner wall of the rotating ring. A supporting ring is fixedly connected to the outer surface of the fixing bolt. The supporting ring is rotatably connected to the rotating groove. A first spring is fixedly connected between the rotating ring and the rotating disc.
[0010] Further, the fixing component includes a T-shaped fixing rod. A fixing hole is provided at the top of the rotating disk corresponding to the card slot, and the T-shaped fixing rod is movably connected to the fixing hole.
[0011] Further, the elastic pulling component includes a T-shaped pulling rod. The bottom end of the T-shaped pulling rod is fixedly connected to the top end of the T-shaped fixing rod. A second spring is fixedly connected between the inner wall of the machine shell and the top end of the T-shaped fixing rod. A holding groove is provided on the front surface of the machine shell. The top end of the T-shaped pulling rod is located inside the holding groove. A pulling frame is rotatably connected to the outer surface of the T-shaped pulling rod inside the holding groove.
[0012] Further, the blocking component includes a connecting cylinder. One end of the connecting cylinder is fixedly connected to the inner wall of the footrest. A rotating shaft is rotatably connected inside the connecting cylinder, and a blocking plate is fixedly connected to the outer surface of the rotating shaft.
[0013] Further, the blocking component further includes a limiting block. The limiting block is fixedly connected to the rotating shaft. A limiting groove is provided on the inner wall of the connecting cylinder corresponding to the limiting block, and the limiting block is movably connected to the limiting groove.
[0014] The utility model has the following beneficial effects:
[0015] 1. By pulling through the elastic pulling component, the fixing component can be made not to fix the rotating disk anymore, so that the footrest at the bottom of the rotating disk can rotate out from the bottom of the machine shell. When the clamping component is clamped with the rotating disk, a resistance will be encountered when the footrest is rotated at this time, which indicates that the footrest has rotated to the predetermined position. Then, the elastic pulling component is released, so that the elastic pulling component pushes the fixing component and makes the fixing component fix the rotating disk again. The setting of the fixing component enables the rotating disk on the footrest to be fixed whether the footrest is at the bottom of the machine shell or supporting the machine shell, so that the footrest will not rotate randomly during use and storage, thereby improving the overall stability of the footrest.
[0016] 2. The utility model rotates the baffle, so that the baffle drives the rotating shaft to rotate inside the connecting cylinder. At the same time, the limiting block rotates inside the limiting groove driven by the rotating shaft. When the limiting block contacts the inner wall on the other side of the limiting groove, the baffle cannot rotate. At this time, the baffle is perpendicular to the footrest. Coupled with the large damping between the rotating shaft and the connecting cylinder, the baffle will not fall down randomly after standing up. At this time, when the operator steps on the footrest, the baffle can block the operator's foot, so that when using the hot melt machine, the foot stepping on the footrest by the operator will not contact the processing position of the hot melt machine, effectively avoiding the phenomenon that the operator's foot is scalded when using the hot melt machine.
[0017] Of course, it is not necessary for any product implementing the utility model to achieve all the above advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the utility model with reference to the accompanying drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the scope of protection of the utility model.
[0028] In the description of the present utility model, it should be understood that the terms "open hole", "upper", "lower", "top", "middle", "inner", etc. indicating the orientation or position relationship are only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the utility model.
[0029] Please refer to Figures 1-6 As shown in the figure, the present utility model is an external footrest structure of a hot melt machine, including a housing 1. A rotating disk 2 is arranged at the bottom of the housing 1. A clamping component 3 is arranged between the bottom of the housing 1 and the top of the rotating disk 2. A footrest 4 is fixedly connected to the bottom of the rotating disk 2. A fixing component 5 is arranged at the top of the rotating disk 2 corresponding to the clamping end of the clamping component 3. An elastic pulling component 6 is arranged at the top end of the fixing component 5. A blocking component 7 is arranged inside the footrest 4.
[0030] The elastic pulling component 6 pulls the fixing component 5 upward, so that the fixing component 5 no longer fixes and limits the rotating disk 2. At this time, the footrest 4 is directly rotated, and the footrest 4 drives the rotating disk 2 to rotate on the clamping component 3. When the footrest 4 rotates out from the top of the housing 1 and rotates to a predetermined position, the clamping component 3 can clamp the rotating disk 2, and then the elastic pulling component 6 is released. At this time, the fixing component 5 fixes the rotating disk 2 again under the push of the elastic pulling component 6.
[0031] Pulling through the elastic pulling component 6 can make the fixing component 5 no longer fix the rotating disk 2, so that the foot support 4 at the bottom of the rotating disk 2 can rotate out from the bottom of the casing 1. When the clamping component 3 is clamped with the rotating disk 2, there will be resistance when the foot support 4 is rotated at this time, which indicates that the foot support 4 has rotated to the predetermined position. Then release the elastic pulling component 6, so that the elastic pulling component 6 pushes the fixing component 5 and makes the fixing component 5 fix the rotating disk 2 again. The setting of the fixing component 5 enables the rotating disk 2 on the foot support 4 to be fixed whether the foot support 4 is at the bottom of the casing 1 or supports the casing 1, so that the foot support 4 will not rotate randomly during use and storage, thus improving the overall stability of the foot support 4.
[0032] In one embodiment, for the above-mentioned clamping component 3, the clamping component 3 includes a fixing bolt 301, the fixing bolt 301 is fixedly connected to the bottom of the casing 1, a clamping cylinder 302 is fixedly connected to the outer surface of the fixing bolt 301, a clamping groove 303 is formed at the bottom of the clamping cylinder 302, a clamping block 304 is clamped inside the clamping groove 303, the clamping block 304 is fixedly connected to the rotating disk 2, and the rotating disk 2 is rotatably connected to the fixing bolt 301.
[0033] There are two clamping grooves 303 at the bottom of the clamping cylinder 302 corresponding to the two states when the foot support 4 is stored and working. When the foot support 4 is rotated out from the bottom of the casing 1, the rotating foot support 4 can drive the rotating disk 2 to rotate, so that the clamping block 304 on the rotating disk 2 can move out from the inside of the clamping groove 303. When the foot support 4 rotates to the predetermined position, the clamping block 304 on the rotating disk 2 can directly move into the inside of another clamping groove 303. The cooperation between the two clamping grooves 303 and the clamping block 304 on the rotating disk 2 can not only be fixed to a certain extent, but also play a positioning role. In one embodiment, for the above-mentioned clamping component 3, the clamping component 3 further includes a rotating ring 305, a rotating groove 306 is formed on the inner wall of the rotating ring 305, a support ring 307 is fixedly connected to the outer surface of the fixing bolt 301, the support ring 307 is rotatably connected to the rotating groove 306, and a first spring 308 is fixedly connected between the rotating ring 305 and the rotating disk 2.
[0034] When the rotating disc 2 rotates, the rotating disc 2 can drive the rotating ring 305 to rotate together on the outer surface of the fixing bolt 301 through the first spring 308. At the same time, as the clamping block 304 contacts the inner wall of the clamping groove 303, with the continuous rotation of the rotating disc 2, the clamping block 304 presses down on the rotating disc 2 through the clamping groove 303, and the rotating disc 2 presses down on the first spring 308, so that the clamping block 304 can move out of the inside of the clamping groove 303. When the footrest 4 on the rotating disc 2 rotates to a predetermined position, at this time, the clamping block 304 corresponds to another clamping groove 303 up and down, so that the first spring 308 jacks up the rotating disc 2 upward and makes the clamping block 304 directly move into the inside of this clamping groove 303. In summary, the setting of the first spring 308 enables the clamping block 304 to move out of the inside of the clamping groove 303 normally. The setting of the support ring 307 and the rotating groove 306 enables the rotating ring 305 to rotate with the rotating disc 2 under the drive of the first spring 308. This setting enables the first spring 308 to better jack up the rotating disc 2 during rotation.
[0035] In one embodiment, for the above-mentioned fixing component 5, the fixing component 5 includes a T-shaped fixing rod 501. A fixing hole 502 is provided at the top of the rotating disc 2 corresponding to the clamping groove 303, and the T-shaped fixing rod 501 is movably connected to the fixing hole 502.
[0036] There are two fixing holes 502 corresponding to the clamping groove 303. When the footrest 4 is at the bottom of the casing 1, the T-shaped fixing rod 501 can be inside one of the fixing holes 502 to fix the rotating disc 2. When the footrest 4 supports the casing 1, the T-shaped fixing rod 501 can be inside the other fixing hole 502 to fix the rotating disc 2. Since the T-shaped fixing rod 502 vertically penetrates the rotating disc 2 through the fixing hole 502, even if a large external force is applied to the footrest 4 when the footrest 4 on the rotating disc 2 is stored or supports the casing 1, the footrest 4 will not rotate, so that the overall stability of the footrest 4 is improved.
[0037] In one embodiment, for the above-mentioned elastic pulling component 6, the elastic pulling component 6 includes a T-shaped pulling rod 601. The bottom end of the T-shaped pulling rod 601 is fixedly connected to the top end of the T-shaped fixing rod 501. A second spring 602 is fixedly connected between the inner wall of the casing 1 and the top end of the T-shaped fixing rod 501. A holding groove 603 is provided on the front surface of the casing 1. The top end of the T-shaped pulling rod 601 is inside the holding groove 603, and a pulling frame 604 is rotatably connected to the outer surface of the T-shaped pulling rod 601 inside the holding groove 603.
[0038] The second spring 602 can push the T-shaped fixing rod 501 downward under the guidance of the T-shaped pulling rod 601, so that the T-shaped fixing rod 501 can move into the corresponding fixing hole 502. At the same time, when the footrest 4 is rotated, the operator holds the housing 1 through the holding groove 603 and pulls the pulling frame 604 upward. As a result, the pulling frame 604 squeezes the second spring 602 upward through the T-shaped pulling rod 601 and the T-shaped fixing rod 501, causing the T-shaped fixing rod 501 to directly move out of the fixing hole 502. Then, the footrest 4 is rotated, and the pulling frame 604 can be released during the rotation. When the footrest 4 rotates to a predetermined position, the T-shaped fixing rod 501 falls into the corresponding fixing hole 502 under the push of the second spring 602 and fixes the rotating disc 2. The above setting enables the pulling frame 604 to be directly pulled when the footrest 4 is rotated, and the operation is relatively convenient. When the pulling frame 604 is not in use, the pulling frame 604 can be rotated so that the whole pulling frame 604 fits against the inner wall of the holding groove 603. This setting ensures that the pulling frame 604 does not cause any obstruction when the hot melt applicator is in use.
[0039] In one embodiment, for the above-mentioned blocking assembly 7, the blocking assembly 7 includes a connecting cylinder 701. One end of the connecting cylinder 701 is fixedly connected to the inner wall of the footrest 4. A rotating shaft 702 is rotatably connected inside the connecting cylinder 701. A blocking plate 703 is fixedly connected to the outer surface of the rotating shaft 702. The blocking assembly 7 further includes a limiting block 704. The limiting block 704 is fixedly connected to the rotating shaft 702. A limiting groove 705 is formed in the inner wall of the connecting cylinder 701 corresponding to the limiting block 704. The limiting block 704 is movably connected to the limiting groove 705.
[0040] When the baffle 703 is inside the footrest 4, the limiting block 704 is in contact with the inner wall of the limiting groove 705. This setting ensures that when the footrest 4 is being stored, the baffle 703 will not rotate downward. At the same time, the top of the baffle 703 is restricted by the top of the housing 1, so that the baffle 703 will not rotate upward either. This makes the baffle 703 more stable during storage. When using the baffle 703, by rotating the baffle 703, the baffle 703 drives the rotating shaft 702 to rotate inside the connecting cylinder 701. At the same time, the limiting block 704 rotates inside the limiting groove 705 driven by the rotating shaft 702. When the limiting block 704 is in contact with the other inner wall of the limiting groove 705, the baffle 703 cannot rotate. At this time, the baffle 703 is perpendicular to the footrest 4. Coupled with the relatively large damping between the rotating shaft 702 and the connecting cylinder 701, the baffle 703 will not fall down randomly after standing up. At this time, when the operator steps on the footrest, the baffle 703 can block the operator's foot, so that when using the hot melt welder, the foot stepping on the footrest 4 by the operator will not come into contact with the processing position of the hot melt welder, effectively avoiding the phenomenon of the operator's foot being scalded when using the hot melt welder. Moreover, the setting of the limiting block 704 and the limiting groove 705 enables the baffle 703 to stand up better and rotate into the footrest 4.
[0041] Through the above technical solutions: 1. By pulling the elastic pulling component 6, the fixing component 5 can be made not to fix the rotating disk 2 anymore, so that the foot support 4 at the bottom of the rotating disk 2 can rotate out from the bottom of the casing 1. When the clamping component 3 is clamped with the rotating disk 2, there will be resistance when the foot support 4 is rotated at this time, which indicates that the foot support 4 has rotated to the predetermined position. Then, the elastic pulling component 6 is released, so that the elastic pulling component 6 pushes the fixing component 5 and makes the fixing component 5 fix the rotating disk 2 again. The setting of the fixing component 5 enables the rotating disk 2 on the foot support 4 to be fixed whether the foot support 4 is at the bottom of the casing 1 or supporting the casing 1, so that the foot support 4 will not rotate randomly during use and storage, thus improving the overall stability of the foot support 4; 2. By rotating the blocking plate 703, the blocking plate 703 drives the rotating shaft 702 to rotate inside the connecting cylinder 701. At the same time, the limiting block 704 rotates inside the limiting groove 705 under the drive of the rotating shaft 702. When the limiting block 704 contacts the inner wall on the other side of the limiting groove 705, the blocking plate 703 cannot rotate, and at this time, the blocking plate 703 is perpendicular to the foot support 4. Coupled with the large damping between the rotating shaft 702 and the connecting cylinder 701, the blocking plate 703 will not fall down randomly after standing up. At this time, when the operator steps on the foot support, the blocking plate 703 can block the operator's foot, so that when using the hot melt machine, the foot of the operator stepping on the foot support 4 will not contact the processing position of the hot melt machine, effectively avoiding the phenomenon that the operator's foot is scalded when using the hot melt machine.
