Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.Note, the aspects described below in conjunction with the drawings and specific embodiments is only exemplary, and should not be understood to carry out any restriction to protection domain of the present utility model.
Fig. 1 shows the schematic diagram of the vent cabinet 100 that can adopt door switch mechanism of the present utility model.As shown in Figure 1, the side (show in figure for just to the side of reader) of vent cabinet 100 is provided with door 110, such as glass door.Door 110 is installed on vent cabinet 110 in the mode moved up and down.Thus, door 110 is opening the door and is moving up respectively at closing time and moving down the opening and closing of the inner space realizing vent cabinet 110.
Due to glass door heavier mass, when not adopting electric open-door, it is very painstaking that experimenter opens the door; Even if use electronic mode to open the door, need to overcome gravity acting owing to opening the door at every turn, therefore, very power consumption.
For this reason, according to one side of the present utility model, provide a kind of door switch mechanism of improvement.The schematic diagram of the door switch mechanism 200 according to one side of the present utility model is showed in Fig. 2.Those skilled in the art understand, although this door switch mechanism 200 is described the glass door switch control rule of the vent cabinet 100 commonly used for laboratory, door switch mechanism of the present utility model is also applicable to the control that other all employings move up and down the door of switch designs.
As shown in Figure 2, door switch mechanism 200 can comprise the first counterweight 201 and the second counterweight 202.The weight of the first counterweight 201 equals the weight sum of door 110 and the second counterweight 202.One end that first counterweight 201 connects at least one drag rope 203 is suspended in midair to be pulled rope 203.Drag rope 203 guides by multiple rope guide 205 other end hanging door 110 making drag rope 203.
First counterweight 201 is also connected to one end of drag rope 203, and namely except drag rope 203, the first counterweight 201 is also pulled rope 204 simultaneously and suspends in midair.Drag rope 204 guides to make the other end of drag rope 204 suspend the second counterweight 202 in midair by least one rope guide 206.
In example as shown in Figure 2, rope guide 205 and rope guide 206 can be arranged on the top of cabinet 120, thus the first counterweight 201 and the second counterweight 202 are suspended to the side of cabinet 120.As shown in the figure, the first counterweight 201 can be suspended to the back side side relative with door 110 with the second counterweight 202.
In example as shown in Figure 2, the first counterweight 201 can be connected to two drag ropes 203, and each root in these two drag ropes guides to door 110 respectively by 3 rope guide 205.Particularly, the both sides of door 110 are respectively provided with a hook 111, and more preferably, this hook 111 can be arranged on the lower end of the side of door 110.Be positioned at the top of cabinet 120 directly over these two hooks 111 and have a rope guide 205 respectively.Two drag ropes 203 are directed to vertically downward to tie up on hook 203 respectively by these two rope guide 205.
In example as shown in Figure 2, drag rope 204 is guided by two rope guide 206, and one end of drag rope 204 connects the first counterweight 201 to suspend the first counterweight 201 in midair, and the other end connects the second counterweight 202 to suspend the second counterweight 202 in midair.Rope guide 205 and rope guide 206 can be pulleys.
Under this design, weight due to the first counterweight 201 equals the weight sum of the second counterweight 202 and door 110, first counterweight 201, second counterweight 202 and the stressed of door 110 reach equilibrium state, and door 110 can pull like a cork up and down, and can rest on optional position.In other words, even manually switch gate 110, experimenter also just can be able to operate when spending minimum strength, and door 110 can rest on any position of desired stop.
Further, door switch mechanism 200 also can comprise electric motor 207.In this example, rope guide 206 can be sprocket wheel 206, and correspondingly drag rope 204 can be the chain 204 with the gear teeth meshing on each sprocket wheel.Now, electric motor 207 can drive sprocket 206 clockwise or be rotated counterclockwise, correspondingly drive the first counterweight 201 to move up or down.When sprocket wheel 206 rotates clockwise under electric motor 207 drives, chain 204 pulls the first counterweight 201 to rise, and under gravity, the second counterweight 202 and door 110 decline, thus realize motor-driven operation of closing the door.When sprocket wheel 206 rotates counterclockwise under electric motor 207 drives, chain 204 pulls the second counterweight 202 to rise, and under gravity, the first counterweight 201 declines, and under the effect of drag rope 203, door 110 rises, thus realizes the operation of motor-driven enabling.
In an embodiment as illustrated in figure 2, sprocket wheel 206 is on the right side furnished with electric motor 207, but those skilled in the art understand, and the sprocket wheel 206 of the side that also can be designed to keep left configures electric motor 207.
Under this design, adopt electric motor 207 with flexibly mode switch door, owing to not needing the gravity acting overcoming whole door 110, therefore, can under the condition of minimum power consumption drive motors motor 207, dramatically saves on electric power.
According to the maneuver autopilot of routine, electric motor 207 can be subject to enabling signal trigger and be rotated counterclockwise, and turning clockwise, or stop operating by stop signal triggering by closing gate signal triggering.
Further, door switch mechanism 200 also can comprise at least one and there is inductor 208.As understood by those skilled in the art, exist when inductor 208 senses target object in its sensing range and export triggering signal.There is door 110 side that inductor 208 can be installed in cabinet 120, as shown in Figure 1, whether to have people before induction door.When sensing that someone exists in front of the door, export enabling signal to trigger electric motor 207.
In one example, door switch mechanism 200 also can comprise the photoelectric sensor 209 on the lower edge being arranged on door 110 whether to have obstruction under induction door.As those skilled in the art understand, when photoelectric sensor 209 senses object in induction range, export triggering signal.Therefore, sense that there is object a below at photoelectric sensor 209, such as, during obstruction, export stop signal to trigger electric motor 207.
When adopting maneuver mode to open the door, also can be provided with control panel 210 to control the operation of whole vent cabinet 100, comprising some necessity realizing door switch mechanism 200 automatically controlled, rotating speed of such as electric motor etc.
According to one side of the present utility model, even need when not configuring motor drive mechanism manually switch gate, experimenter also just can be able to operate when spending minimum strength, and door can rest on any position of desired stop.
According to another aspect of the present utility model, when being configured with motor drive mechanism, also can improve the power consumption of power driven system, saving suitable electric power.
Description before providing is to make any technician in this area all can put into practice various aspects described herein.But should be appreciated that, protection domain of the present utility model should be as the criterion with claims, and should not be defined to concrete structure and the assembly of above explained orally embodiment.Those skilled in the art, in spirit and scope of the present utility model, can carry out various variation and amendment to each embodiment, and these variations and amendment also drop within protection domain of the present utility model.
