Description

Technical Field

[0001] This utility model relates to the technical field of three-station one-button sequential control mechanism, specifically a three-station mechanism indicator transmission device. Background Technology

[0002] A conventional three-position one-button sequential control mechanism can complete the closing and opening actions of multiple limit switches under the drive of the drive unit. As shown in the three-position operating mechanism one-button sequential control device in publication number CN218676827U, it can provide feedback on the opening and closing status of the above mechanism through the rotation of the drive unit. However, it usually does not have an external feedback structure, making it difficult for operators to observe the status. Even by reserving an observation window in the housing or setting up indicator lights, it is not easy to provide direct feedback of information. Utility Model Content

[0003] To solve the above problems, this utility model provides a three-station mechanism indicating transmission device.

[0004] The technical solution of this utility model is as follows: A three-position mechanism indicating transmission device includes a one-button sequential control mechanism installed inside a housing. The one-button sequential control mechanism also has a movable plate on one side near the housing, and the movable plate can move synchronously with the drive mechanism of the one-button sequential control mechanism. The housing has one or more rotating seats on the outer surface near the movable plate. The rotating seats have indicator signs on the outer side of the housing. The rotating seats are connected to the movable plate on the inner side of the housing and can be driven to rotate by the movable plate. Furthermore, the rotation direction of the movable plate driving the rotating seat can be reversed.

[0005] Information can be fed back by setting a rotating indicator, and the feedback is achieved by the cooperation of the aforementioned movable plate and drive mechanism. Therefore, the feedback is real-time, and this method makes it easy to observe the opening and closing information directly from outside the housing.

[0006] The movable plate is moved in the following manner: the movable plate includes a movable reference plate, and a rack is provided on the side of the reference plate near the one-key sequential control mechanism. The one-key sequential control mechanism is provided with a driven gear that rotates synchronously with the drive mechanism near the rack, and the driven gear meshes with the rack.

[0007] As a preferred embodiment, the rack can be fixed to the reference plate at multiple positions along the rack's movement direction.

[0008] The rotating seat is driven to rotate by means that an adjusting component is provided at the end of the rotating seat away from the indicator, and the adjusting component has an elongated hole along its length. The movable plate is provided with a column and can move within the elongated hole.

[0009] The column positioning method is that the movable plate is provided with multiple openings for fixing the column.

[0010] To facilitate positioning, multiple openings are provided along the length of the movable plate.

[0011] To enable the driving of various signs, multiple openings are provided in the width direction of the movable plate.

[0012] In order to enable forward and reverse driving of the sign, the opening is provided on both the upper and lower sides of the rotating base.

[0013] To improve adaptability, the rotating base can be fixed in multiple positions on the housing.

[0014] The column is fixed in place by means of an adhesive.

[0015] The beneficial effects of this utility model are as follows: This utility model is a three-position mechanism indicating transmission device. Based on the existing three-position one-key sequential control mechanism, by adding a gear and rack drive structure, it can realize the movement drive of the reference plate. In addition, with the help of the adjustment component, it can realize the drive of the indicator on the outside of the housing. Through the above method, the closing information of the internal one-key sequential control mechanism can be displayed and fed back in real time by the rotation of the indicator. Moreover, the rotation of the indicator can realize forward and reverse rotation and rotation at different angles according to the setting position and setting method of the column on the reference plate and the setting position of the rotating seat, etc., which makes it more adaptable. Attached Figure Description

[0016] The advantages and solutions of this application will become clear to those skilled in the art upon reading the following detailed description of preferred embodiments. The accompanying drawings are for illustrative purposes only and are not intended to limit the scope of this invention.

[0017] In the attached diagram: Figure 1 This is a top view of the structure of this utility model; Figure 2 This is a front view structural diagram of the present invention; Figure 3 for Figure 2 Schematic diagram of a partial structure; Figure 4 This is a schematic diagram of part of the structure of this utility model; The components represented by the various reference numerals in the diagram are: 1. One-button sequential control mechanism; 2. Driven gear; 3. Movable plate; 31. Rack; 32. Reference plate; 33. Column; 4. Rotating seat; 5. Indicator; 6. Adjusting component. Detailed Implementation

[0018] Example like Figure 1 , 2 The three-position mechanism indicating transmission device shown includes a one-button sequential control mechanism 1 set inside the housing. Its structure will not be described in detail. It can trigger switches at multiple positions, and the position can be directly fed back by rotating gears. Therefore, only the rotation angle of the gears is needed to deduce the actual switch state. For this feature, the one-button sequential control mechanism 1 also has a movable plate 3 on one side near the housing. The movable plate 3 can move synchronously with the drive mechanism of the one-button sequential control mechanism 1. Therefore, in this way, the actual state of each switch can be fed back from the movement of the movable plate 3. As the gears rotate, driving the switch to switch states, they also correspondingly drive the movable plate 3 to move. Since the movable plate 3 is located inside the housing and cannot be observed, only the movement information from the movable plate 3 needs to be fed back to obtain the desired feedback information.

[0019] Furthermore, based on the above structure, the housing is further provided with one or more rotating seats 4 on the outer surface near the movable plate 3, and the rotating seats 4 are provided with indicator plates 5 on the outer side of the housing. Different information can be fed back simply by rotating the indicator plates 5. Therefore, it is only necessary for the movable plate 3 to drive the indicator plates 5 to rotate. For this purpose, the rotating seats 4 are connected to the movable plate 3 on the inner side of the housing and can be driven to rotate by the movable plate 3. In this way, the travel distance of the driving unit can be fed back through the indicator plates 5, and the indicator plates 5 can be driven to rotate according to the corresponding rotation angle, thereby realizing the switching of feedback information.

[0020] Furthermore, in order to be suitable for different scenarios, the rotation direction of the movable plate 3 driving the rotating seat 4 can be reversed, that is, the rotation direction of the indicator 5 can be switched. When multiple indicator 5s are set, one can rotate forward and the other can rotate in reverse.

[0021] Based on the above structure, information can be fed back by setting a rotating indicator 5. The feedback information is achieved through the cooperation of the movable plate 3 and the drive mechanism, so the feedback information is real-time. This method also makes it easy to observe the opening and closing information directly from outside the housing. The way to observe the information is also relatively convenient, and the cooperation of the mechanical structure is more stable.

[0022] As a preferred embodiment, such as Figure 3As shown, the movable plate 3 moves as follows: the movable plate 3 includes a movable reference plate 32, and a rack 31 is provided on the side of the reference plate 32 near the one-key sequential control mechanism 1. The one-key sequential control mechanism 1 has a driven gear 2 that rotates synchronously with the driving mechanism near the rack 31, and the driven gear 2 meshes with the rack 31. The feedback of the rotation stroke can be achieved by the synchronous rotation of the driven gear 2 and the driving gear of the one-key sequential control mechanism, and then the driving effect of the reference plate 32 is achieved by the meshing of the rack and the gear. However, it should be noted that, for adaptability considerations, the rack 31 can be fixed with the reference plate 32 at multiple positions along the moving direction of the rack 31. That is to say, the initial position of the reference plate 32 can be adjusted.

[0023] In a preferred embodiment, the rotating base 4 is driven to rotate by means of an adjusting member 6 located at the end of the rotating base 4 furthest from the indicator 5. The purpose of the adjusting member 6 is to work in sync with the movable plate 3 to achieve synchronous movement and to convert the lateral movement into driving the indicator 5 to rotate. The specific arrangement is as follows: Figure 4 As shown, the adjusting member 6 is provided with an elongated hole along its length. The movable plate 3 is provided with a column 33 and can move within the elongated hole. Since the position of the rotating shaft is fixed, the column 33 can move within the elongated hole and push the adjusting member 6 to rotate during the movement of the movable plate 3, thereby achieving the desired driving effect.

[0024] Furthermore, in the above structure, the column 33 is positioned by the movable plate 3 having multiple openings for fixing the column 33. The column 33 is fixed in the openings using adhesive. Alternatively, the openings can be threaded, and the column 33 can be externally threaded for a rotatable connection, thus achieving fixation.

[0025] In order to achieve forward and reverse driving of the indicator 5, the openings are provided on both the upper and lower sides of the rotating base 4. The column 33 moves in the same direction on both the upper and lower sides of the rotating shaft, which will produce driving effects in different directions, and can be selected for application when needed.

[0026] Furthermore, in the above structure, to facilitate positional adaptation, multiple openings are provided along the length of the movable plate 3. And to enable the driving of various indicator signs 5, multiple openings are provided along the width of the movable plate 3. The multiple openings along the width direction allow the adjusting member 6 to rotate at different angles according to the actual stroke of the movable plate 3; therefore, adaptation and adjustment are required based on actual needs.

[0027] Finally, to improve adaptability, the rotating base 4 can be fixed in multiple positions on the housing for easy observation and use.
