[0002] The ventilation system includes a fume hood, in which a sliding door is a component. The height at which the sliding door moves relative to the cabinet body adjusts the exhaust volume in the fume hood; the wider the sliding door is opened, the greater the exhaust volume.
[0003] Currently, sliding doors are installed on the cabinet using a synchronous belt and counterweight structure. During operation, the experimenters push or pull the sliding door up or down according to their habits to change the exhaust volume of the cabinet. However, in actual use, the experimenters have different operating habits, and the sliding door is often over-opened, resulting in unnecessary large air volume exhaust and energy waste. Utility Model Content
[0004] Based on this, the purpose of this utility model is to provide a sliding door height limiting mechanism and a ventilation device to solve the technical problem in the background art that excessive opening of sliding doors will lead to unnecessary large-volume exhaust and energy waste.

The first limiting component is used to be disposed on one of the sliding door and the cabinet, and the second limiting component is used to be disposed on the other of the cabinet and the sliding door. The first limiting component includes a retractable insertion part and an elastic pressing unit; When pressure is applied to the elastic pressing unit, the insertion component is driven to retract and separate from the second limiting component to release the movement restriction of the sliding door. When the pressure is removed, the elastic pressing unit, under the action of elastic reset, drives the insertion component to extend and engage with the second limiting component to restrict the movement of the sliding door.
[0006] Furthermore, the second limiting component is at least one limiting hole formed on the cabinet body, and the first limiting component is used to be disposed on the sliding door.
[0007] Furthermore, the elastic pressing unit includes at least one pressing area, at least one elastic reset area, and at least one driving area; The driving region is used to drive the insertion component to the pressing region, and the elastic reset region is used to apply an elastic driving force to the driving region, so that the driving region drives the insertion component to move into the limiting hole to restrict the movement of the sliding door. The pressing area is used to apply pressure to the elastic reset area, so that the driving area drives the insertion component to separate from the limiting hole body, thereby releasing the movement restriction of the sliding door.
[0008] Furthermore, the limiting mechanism also includes an assembly housing for mounting on the sliding door and a mounting bracket for mounting within the assembly housing, wherein the elastic pressing unit is mounted on the assembly housing via the mounting bracket.
[0009] Furthermore, the assembly housing is provided with a guide cavity, which is used to guide the insertion component.
[0010] Furthermore, the first limiting component includes two insertion parts and two elastic pressing units; Each of the aforementioned insertion components is respectively provided with a corresponding elastic pressing unit, and the cabinet is provided with two limiting holes corresponding to each of the aforementioned insertion components.
[0011] Furthermore, the two insertion components are symmetrically arranged, and the two elastic pressing units are symmetrically arranged.
[0012] Furthermore, the pressing areas of the two elastic pressing units are integrated to simultaneously drive the two insertion components to move through a single pressing area.
[0013] Furthermore, the driving area is a connecting rod with a bent portion, and a connecting shaft for rotatably connecting one end of the connecting rod to the pressing area; The bent portion is rotatably connected to the mounting bracket, and the end of the connecting rod away from the connecting rod body is connected to the insertion component; In this configuration, the two bent portions in the two driving regions are sequentially overlapped on the connecting shaft, and each connecting rod body has a through hole in a portion of its area near the connecting shaft for the connecting shaft to move.
[0014] Another aspect of this utility model is to provide a ventilation device, including a cabinet, a sliding door, and the aforementioned limiting mechanism.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: In the sliding door height limiting mechanism provided by this utility model, by assembling the limiting mechanism of this application on a ventilation device, and the limiting mechanism including a first limiting component and a second limiting component, the first limiting component is used to be disposed on one of the sliding door and the cabinet, and the second limiting component is used to be disposed on the other of the cabinet and the sliding door, so that when the sliding door moves, the position of the second limiting component can be preset, so that when the sliding door moves to the position opposite to the second limiting component, the first limiting component includes a retractable insertion part and an elastic pressing unit, so that when the elastic pressing unit is not subjected to pressure, the elastic pressing unit drives the insertion part to extend and engage with the second limiting component under the action of elastic reset, thereby restricting the movement of the sliding door. With this setting, the technical problem of excessive opening of the sliding door, which leads to unnecessary large-volume exhaust and energy waste can be solved. At the same time, combined with the fact that when pressure is applied to the elastic pressing unit, the insertion part can be driven to retract and separate from the second limiting component, thereby releasing the movement restriction of the sliding door, and with this setting, the purpose of simple operation can also be achieved.

Several embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0021] First Embodiment Please see Figures 1-4 The figure shows a sliding door height limiting mechanism in one embodiment of the present invention. The limiting mechanism is used to be assembled on a ventilation device. The ventilation device includes a cabinet 200 and a movable sliding door 100. It should be noted that in this example, the ventilation device is not limited to the sliding door 100 and cabinet 200 shown in this example. It may also include other components constituting the ventilation device. Since other components are conventional prior art in this field, they will not be specifically described here.
[0022] To address the technical problem in the prior art where excessive opening of the sliding door 100 leads to unnecessary large-volume exhaust and energy waste, in this embodiment, the limiting mechanism includes a first limiting component 300 and a second limiting component 400. The first limiting component 300 is disposed on one of the sliding door 100 and the cabinet 200, and the second limiting component 400 is disposed on the other of the cabinet 200 and the sliding door 100. The first limiting component 300 includes a retractable insertion part 310 and an elastic pressing unit 320; When pressure is applied to the elastic pressing unit 320, the insertion member 310 is driven to retract and separate from the second limiting component 400 to release the movement restriction of the sliding door 100. When the pressure is removed, the elastic pressing unit 320, under the action of elastic reset, drives the insertion member 310 to extend and engage with the second limiting component 400 to restrict the movement of the sliding door 100.
[0023] In practical implementation, the limiting mechanism shown in this example includes a first limiting component 300 and a second limiting component 400. When the sliding door 100 moves, the position of the second limiting component 400 can be preset. When the sliding door 100 moves to a position opposite to the second limiting component 400, the first limiting component 300 includes a retractable insertion member 310 and an elastic pressing unit 320. When the elastic pressing unit 320 is not under pressure, it elastically resets, causing the insertion member 310 to extend and engage with the second limiting component 400, thus restricting the movement of the sliding door 100. This design solves the technical problem of excessive opening of the sliding door 100, leading to unnecessary large-volume exhaust and energy waste. Furthermore, in conjunction with the application of pressure to the elastic pressing unit 320, the insertion member 310 can retract and separate from the second limiting component 400, releasing the movement restriction on the sliding door 100. This design also simplifies operation.
[0024] Specifically, the second limiting component 400 is at least one limiting hole formed on the cabinet 200, and the first limiting component 300 is used to be disposed on the sliding door 100.
[0025] The elastic pressing unit 320 includes at least one pressing area 321, at least one elastic reset area 322, and at least one driving area 323; The driving region 323 is used to drive the insertion member 310 to the pressing region 321, and the elastic reset region 322 is used to apply an elastic driving force to the driving region 323, so that the driving region 323 drives the insertion member 310 to move into the limiting hole to restrict the movement of the sliding door 100. Pressing area 321 is used to apply pressure to elastic reset area 322, so that driving area 323 drives insertion member 310 to separate from limiting hole body, thereby releasing the movement restriction of sliding door 100.
[0026] Specifically, please refer to Figure 2 As shown, in this example, the elastic reset area 322 can be a spring in the prior art, and the drive area 323 specifically refers to the connecting rod 3231 with a bent part and the connecting shaft 3232 for rotatably connecting one end of the connecting rod 3231 to the pressing area 321. The bent part is rotatably connected to the mounting bracket 340, and the end of the connecting rod 3231 away from the connecting rod 3231 is connected to the insertion part 310.
[0027] In some preferred embodiments, the limiting mechanism further includes an assembly housing 330 for being disposed on the sliding door 100 and a mounting bracket 340 for being disposed within the assembly housing 330, wherein the elastic pressing unit 320 is mounted on the assembly housing 330 via the mounting bracket 340.
[0028] To ensure that the insertion component 310 can be smoothly inserted into the limiting hole, in this example, the assembly housing 330 is provided with a guide cavity 331. The guide cavity 331 is used to guide the insertion component 310, and the normal operation of the insertion component 310 can be ensured by using the guide cavity 331.
[0029] It should be noted that, given that the insertion component 310 is relatively long in actual use, the mounting bracket 340 is used to be set in the middle of the assembly housing 330. Specifically, the first limiting component 300 includes two insertion components 310 and two elastic pressing units 320, wherein each insertion component 310 is respectively provided with a corresponding elastic pressing unit 320, and the cabinet 200 is provided with two limiting holes corresponding to each insertion component 310. Through the arrangement of the two insertion components 310, the two elastic pressing units 320 and the two limiting holes, the two sides of the sliding door 100 can be fixed.
[0030] In addition, the two insertion parts 310 are symmetrically arranged, and the two elastic pressing units 320 are symmetrically arranged. For details, please refer to the following document again. Figure 2 As shown, the pressing areas 321 in the two elastic pressing units 320 are integrated to drive the two insertion parts 310 to move simultaneously through one pressing area 321. The two bent parts in the two driving areas 323 are successively overlapped on the connecting shaft 3232. Each connecting rod 3231 has a through hole 3233 in a part of its area near the connecting shaft 3232 for the connecting shaft 3232 to move.
[0031] In summary, the sliding door height limiting mechanism of this utility model has at least the following beneficial effects: In the sliding door height limiting mechanism provided by this utility model, the limiting mechanism of this application is assembled on a ventilation device, and the limiting mechanism includes a first limiting component 300 and a second limiting component 400. The first limiting component 300 is used to be disposed on one of the sliding door 100 and the cabinet 200, and the second limiting component 400 is used to be disposed on the other of the cabinet 200 and the sliding door 100. This allows the position of the second limiting component 400 to be preset when the sliding door 100 moves, so that when the sliding door 100 moves to a position opposite to the second limiting component 400, the first limiting component 300 includes a retractable insertion part 310 and a spring. The elastic pressing unit 320, when not under pressure, causes the insertion member 310 to extend and engage with the second limiting component 400 under the action of elastic reset, thereby restricting the movement of the sliding door 100. This design solves the technical problem that excessive opening of the sliding door 100 leads to unnecessary large-volume exhaust and energy waste. Furthermore, when pressure is applied to the elastic pressing unit 320, it causes the insertion member 310 to retract and separate from the second limiting component 400, thus releasing the movement restriction on the sliding door 100. This design also simplifies operation.
[0032] Second Embodiment Please see Figures 1-4 The image shows a ventilation device in one embodiment of the present invention, including a cabinet 200, a sliding door 100, and the limiting mechanism in the first embodiment above. It should be noted that in this example, the ventilation device is not limited to the sliding door 100 and the cabinet 200 shown in this example. It may also include other components constituting the ventilation device. Since other components are conventional prior art in this field, they will not be specifically described here.
[0033] In summary, the ventilation device provided in this embodiment has at least the following beneficial effects: In the ventilation device provided by this utility model, a limiting mechanism is assembled on the ventilation device. The limiting mechanism includes a first limiting component 300 and a second limiting component 400. The first limiting component 300 is disposed on one of the sliding door 100 and the cabinet 200, and the second limiting component 400 is disposed on the other of the cabinet 200 and the sliding door 100. This allows the position of the second limiting component 400 to be preset when the sliding door 100 moves. When the sliding door 100 moves to a position opposite to the second limiting component 400, the first limiting component 300 includes a retractable insertion part 310 and an elastic pressing element. The design of element 320 allows the elastic pressing unit 320 to extend and engage with the second limiting component 400 under elastic reset when no pressure is applied, thereby restricting the movement of the sliding door 100. This design solves the technical problem of excessive opening of the sliding door 100 leading to unnecessary large-volume exhaust and energy waste. Furthermore, when pressure is applied to the elastic pressing unit 320, it can retract the insert component 310 and separate it from the second limiting component 400, thereby releasing the movement restriction on the sliding door 100. This design also simplifies operation.
