Description
Technical Field
[0001] This utility model relates to the field of cleaning and disinfection equipment technology, specifically to a limiting structure and a cleaning and disinfection conveying device. Background Technology
[0002] Decontamination refers to the measures taken to disinfect and eliminate contamination of personnel, equipment, materials, fortifications, roads, etc., contaminated with toxic agents, biological warfare agents, or radioactive materials. Existing decontamination equipment consists of a decontamination preparation station, a decontamination station, and a decontamination evacuation station. Objects to be decontaminated are transferred from the decontamination preparation station to the decontamination station via a conveyor system. Decontamination is then performed on the objects, and the decontamination-completed objects are removed from the decontamination evacuation station. The decontamination equipment is equipped with limiting components to isolate each station, allowing each station to operate independently and in an orderly manner. For example, if an object at a decontamination station has not yet been decontaminated, the object at the decontamination preparation station is blocked by the limiting component. Once the object at the decontamination station has been decontaminated, the limiting component releases it, allowing the next object to enter the decontamination station.
[0003] However, existing decontamination equipment still has shortcomings. For example, the limiting component of the decontamination equipment is an electric check valve. Electric check valves are not only expensive, but they also cannot be used normally when there is a circuit failure, resulting in a high frequency of maintenance. Utility Model Content
[0004] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose a limiting structure and a washing and disinfection conveying device to solve the technical problem that the limiting component of the existing washing and disinfection equipment is an electric one-way valve, which is not only expensive, but also cannot be used normally when there is a circuit failure, and has a high maintenance frequency.
[0005] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution: This utility model provides a limiting structure, including: Frame; and A limiting assembly includes a limiting plate, a rotating shaft, and a limiting strip. The limiting plate is connected to the rotating shaft, and the limiting plate is located at a first part and a second part on both sides of the rotating shaft, respectively. The rotating shaft is rotatably connected to the frame, and the limiting strip is disposed on the frame and can limit the first part or the second part when the limiting plate rotates.
[0006] In some embodiments, the width of the first portion is smaller than the width of the second portion, and the limiting strip is located directly below the rotating shaft.
[0007] In some embodiments, two of each of the rotating shafts and the limiting strips are provided. The two rotating shafts are respectively rotatably disposed on both sides of the frame. The two sides of the limiting plate are respectively connected to the two rotating shafts. The two limiting strips are respectively disposed on both sides of the frame and can simultaneously abut against the limiting plate.
[0008] In some embodiments, the width of the first portion is equal to the width of the second portion, and the limiting component further includes a counterweight disposed on the second portion.
[0009] In some embodiments, the second part has a plurality of slots, each of which can be detachably inserted into the counterweight.
[0010] In some embodiments, the limiting structure further includes a guide roller, which is rotatably connected to the frame, and the rotation axis of the guide roller is parallel to the rotation axis of the rotating shaft.
[0011] In some embodiments, the frame has a support surface, and when the limiting strip abuts against the first part or the second part, the limiting plate extends beyond the support surface.
[0012] Secondly, this utility model also provides a washing and disinfection conveying device, including a first station, a second station, a third station, and the aforementioned limiting structure. The limiting structure is provided between the first station and the second station, and the limiting structure is provided between the second station and the third station for self-testing.
[0013] In some embodiments, the limiting structure is detachably connected to the second workstation and the third workstation via an interference fit.
[0014] In some embodiments, both the first station and the second station are provided with drive rollers, which are used to drive the object to be cleaned and disinfected to move and pass through the limiting structure.
[0015] Compared with existing technologies, the limiting structure provided by this utility model can be applied to decontamination equipment, isolating each workstation and allowing each workstation to operate independently. The limiting structure features a limiting plate rotatably connected to the frame via a rotating shaft. When rotated, the limiting plate's first or second part abuts against the limiting strip, thus limiting its movement. The side of the limiting plate facing away from the limiting strip is not limited, allowing objects on that side to step over it and move to the other side. The side of the limiting plate facing the limiting strip is limited, preventing objects on that side from stepping over it to reach the other side. Therefore, operators can rotate the limiting plate to the appropriate side as needed to achieve the limiting effect on the target side. This utility model's limiting structure is purely mechanical, requires no electricity, is low-cost, virtually eliminates malfunctions, and requires minimal maintenance. Attached Figure Description

Detailed Implementation
[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0018] To address the technical problems of existing decontamination equipment using electric check valves as the limiting components, which are not only costly but also prone to failure and frequent maintenance in case of circuit malfunctions, this invention provides a limiting structure that enables the decontamination equipment to be zoned and isolated, allowing each station to operate independently. Furthermore, the limiting structure is purely mechanical, requires no electricity, is virtually malfunction-free, and requires minimal maintenance.
[0019] It should be noted that the limiting structure described in this utility model is used in, but not limited to, decontamination conveying devices. For ease of explanation, this utility model only uses the application of the limiting structure in a decontamination conveying device as an example. The principle of the limiting structure applied in other types of equipment is essentially the same as that applied in a decontamination conveying device, and will not be described in detail here.
[0020] Please see Figure 1 , Figure 1This is a schematic diagram of the limiting structure in one embodiment of the present invention. The limiting structure 100 includes a limiting component 1 and a frame 2. The limiting component 1 includes a limiting plate 11, a rotating shaft 12, and a limiting strip 13. The limiting plate 11 is connected to the rotating shaft 12, and the rotating shaft 12 is rotatably connected to the frame 2, so that the limiting plate 11 is rotatably connected to the frame 2 through the rotating shaft 12, and the limiting plate 11 can rotate relative to the frame 2 through the rotating shaft 12. The limiting plate 11 has a first part 111 and a second part 112 on both sides of the rotating shaft 12, which can be understood as the rotating shaft 12 connecting the two ends of the limiting plate 11 in the width direction, and the rotating shaft 12 dividing the limiting plate 11 into upper and lower parts. Figure 1 In the embodiment shown, the portion of the limiting plate 11 above the rotating shaft 12 is the first portion 111, and the portion of the limiting plate 11 below the rotating shaft 12 is the second portion 112.
[0021] The limiting strip 13 is provided on the frame 2 and can limit the first part 111 or the second part 112 when the limiting plate 11 rotates. Figure 1 In the embodiment shown, the limiting strip 13 is currently abutting against the second part 112. At this time, the limiting plate 11 can only rotate counterclockwise and cannot rotate clockwise. The limiting plate 11 can... Figure 1 The device is positioned to the right to limit the movement of objects on frame 2, preventing them from moving to the right.
[0022] The operator can manually rotate the limiting plate 11 counterclockwise 180° so that the first part 111 faces downwards and the second part faces upwards. The first part 111 abuts against the limiting strip 13, and the second part 112 disengages from the limiting strip 13. At this time, the limiting plate 11 can only rotate clockwise and cannot rotate counterclockwise. The limiting plate 11 can... Figure 1 The device is positioned to the left to prevent objects on frame 2 from moving to the left.
[0023] The limiting structure 100 in this embodiment can be applied to a decontamination conveying device to isolate multiple stations within the device. The limiting structure 100 can be installed between adjacent stations. By rotating the limiting plate 11, the limiting direction of the limiting plate 11 can be switched to limit objects moving in the target direction, thereby isolating adjacent stations. For example, if an object to be decontaminated flows from the first station to the second station, and the object at the second station has not yet completed decontamination, the limiting plate 11 can be switched to a limiting state to prevent the next object to be decontaminated at the first station from moving to the second station via the limiting structure 100. When the object at the second station has completed decontamination, the limiting plate 11 can be rotated to a free-flowing state, allowing the object at the first station to step over the limiting plate 11 and move to the second station for decontamination.
[0024] In one embodiment, please refer to Figure 2The width of the first part 111 is smaller than the width of the second part 112, and the limiting strip 13 is located directly below the rotating shaft 12. Figure 1 In the illustrated embodiment, the rotating shaft 12 is not connected to the middle of the limiting plate 11 in the width direction, but rather to a position slightly above the limiting plate 11. This can be understood as an eccentric connection between the rotating shaft 12 and the limiting plate 11. The portion of the limiting plate 11 below the rotating shaft 12, i.e., the second portion 112, has a greater weight than the first portion 111. Figure 1 The second part 112 in the illustrated embodiment abuts against the limiting strip 13 by its own weight. When the object to be decontaminated is... Figure 1 When the object moves from right to left in the illustrated embodiment, the limiting plate 11 does not restrict its movement; the object can press against the limiting plate 11. The limiting plate 11 rotates to a horizontal position, and the object moves smoothly to the left along the horizontal limiting plate 11. After the object completely passes over the limiting plate 11, the limiting plate 11 automatically rotates under its own weight to re-engage with the limiting strip 13, completing its reset. Then, the limiting plate 11 is rotated 180° counterclockwise so that the first part 111 engages with the limiting strip 13, blocking the next object to be cleaned on the right side of the limiting plate 11 and preventing it from entering the left side of the limiting plate 11. This embodiment, by eccentrically setting the limiting plate 11 and the rotating shaft 12, allows the limiting plate 11 to automatically reset and can be switched between both sides of the limiting strip 13.
[0025] In one embodiment, please refer to Figure 1 Two rotating shafts 12 and two limiting strips 13 are provided. The two rotating shafts 12 are respectively rotatably located on both sides of the frame 2. The two sides of the limiting plate 11 are respectively connected to the two rotating shafts 12, and the two limiting strips 13 are respectively located on both sides of the frame 2 and can simultaneously abut against the limiting plate 11. In this embodiment, by using two limiting strips 13 to simultaneously abut against the limiting plate 11, a more stable limiting effect can be achieved. Using two rotating shafts 12 to simultaneously support the limiting plate 11 allows the limiting plate 11 to rotate more stably.
[0026] In one embodiment, please refer to Figure 3 The width of the first part 111 is equal to the width of the second part 112, and the limiting component 1 also includes a counterweight 14 disposed on the second part 112. The difference between this embodiment and the previous embodiment is that in this embodiment, the rotating shaft 12 is connected to the middle position in the width direction of the limiting plate 11. When the limiting plate 11 rotates to switch its position, the counterweight can function, for example... Figure 1 In the state shown, the counterweight can increase the weight of the second part 112 so that the second part 112 can automatically reset by gravity to abut against the limit bar 13.
[0027] Further, please refer to Figure 2The second part 112 has multiple slots 113, and each slot 113 can be detachably connected to a counterweight 14. According to actual needs, a counterweight 14 can be selectively installed in one or more slots 113 so that the second part 112 can automatically reset in time, which helps to improve its response speed.
[0028] In one embodiment, please refer to Figure 1 The limiting structure 100 also includes a guide roller 3, which is rotatably connected to the frame 2. The rotation axis of the guide roller 3 is parallel to the rotation axis of the rotating shaft 12. In this embodiment, by setting the guide roller 3, the object to be decontaminated can continue to move along the guide roller 3 after passing the limiting plate 11. The guide roller 3 provides support and guidance for the object to be decontaminated, allowing it to move smoothly. Furthermore, the number of guide rollers 3 is not limited; one or more can be provided. Figure 1 The illustrated embodiment has two guide rollers 3, which can provide a larger support area.
[0029] In one embodiment, please refer to Figure 1 The frame 2 has a support surface 21. When the limiting strip 13 abuts against the first part 111 or the second part 112 of the limiting plate 11, the limiting plate 11 extends beyond the support surface 21. In addition to supporting components such as the limiting plate 11 and the guide roller 3, the frame 2 in this embodiment can also provide a support surface for the object to be cleaned and disinfected. For example, during the movement of the object to be cleaned and disinfected, it can contact the support surface 21 at the top of the frame 2 so that the object to be cleaned and disinfected can slide along the support surface 21.
[0030] Secondly, please refer to Figure 4 This utility model also provides a washing and disinfection conveying device 200, including a first station 4, a second station 5, a third station 6 arranged sequentially, and the aforementioned limiting structure 100. There are two limiting structures 100, one located between the first station 4 and the second station 5, and the other located between the second station 5 and the third station 6. Each of the first station 4, the second station 5, and the third station 6 is equipped with a drive roller 7. The object to be washed and disinfected 8 is placed on top of the drive roller 7. The drive roller 7 is connected to a corresponding motor, which drives the drive roller 7 to rotate, so that the drive roller 7, through friction, drives the object to be washed and disinfected to pass sequentially through the first station 4, the second station 5, and the third station 6.
[0031] Please see Figure 5When the limiting plate 11 is located between the limiting strip 13 and the first station 4, the object 8 to be cleaned and disinfected at the first station 4 can drive the limiting plate 11 to rotate and pass over the limiting plate 11 to reach the second station 5. However, the limiting plate 11 has a limiting effect on the object at the second station 5, which can restrict the object at the second station 5 from moving back to the first station 4, thereby preventing the object that has been cleaned and disinfected at the second station 5 from moving back to the first station 4 and causing contamination of the object.
[0032] Please see Figure 6 At this time, the limiting plate 11 is located between the second station 5 and the third station 6. Due to the limiting effect of the limiting strip 13, the limiting plate 11 can restrict the object in the second station 5 from entering the third station 6. The second station 5 is equipped with a decontamination component (not shown in the figure) for decontaminating the object. Figure 6 The limiting plate 11 restricts the object from moving out of the second station 5, so that the object can stably complete the decontamination at the second station 5. When the object has completed decontamination at the second station 5, the limiting plate 11 can be manually rotated 180° clockwise. The limiting plate 11 will release the object from the restriction, and the decontamination-completed object can step on the limiting plate 11 and move to the third station 6 for recycling.
[0033] In one embodiment, please refer to Figure 2 The connection method between the aforementioned limiting structure 100 and the second station 5 and the third station 6 is not limited. It can be fixedly connected by welding or detachably connected by plugging. In this embodiment, an interference fit is preferred. Specifically, the frame 2 of the limiting structure 100 is inserted into the second station 5 and the third station 6 with an interference fit, which makes it easy to assemble and disassemble the limiting structure 100.
[0034] To better understand this utility model, the following is combined with... Figures 1 to 6 The technical solution of this utility model is described in detail below: The limiting structure provided by this utility model can be applied to decontamination equipment, isolating each workstation and allowing each workstation to operate independently. The limiting structure 100 has a limiting plate 11 rotatably connected to the frame 2 via a rotating shaft 12. When rotating, the limiting plate 11's first part 111 or second part 112 abuts against the limiting strip 13, thus limiting the position of the limiting plate 11. The side of the limiting plate 11 facing away from the limiting strip 13 is not limited, allowing objects on that side to step over the limiting plate 11 and move to the other side. The side of the limiting plate 11 facing the limiting strip 13 is limited, preventing objects on that side from stepping over the limiting plate 11 to reach the other side. Therefore, operators can rotate the limiting plate 11 to a suitable side as needed to achieve the limiting effect on the target side. The limiting structure of this utility model is a purely mechanical structure, requiring no electricity, has low cost, virtually eliminates malfunctions, and requires minimal maintenance.
[0035] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
