[0002] In the processes of machining, product inspection, and assembly and debugging, a large number of tooling fixtures are required to reliably clamp and position the workpiece. Meeting the leveling accuracy requirements is a basic requirement for leveling tooling. The leveling of the working plane of many tooling fixtures is accomplished by adjusting the adjusting screws or adjustable supports on the tooling. Due to the need to adjust different support points and the existence of manufacturing errors during the leveling process, different leveling directions on the same plane will affect and interfere with each other, i.e., leveling coupling.

[0003] Publication No. CN 205446698 U discloses an automatic leveling structure, including a panel, a support base, a sealing ring, and a sealing cover. The panel is provided with a movable groove, the support base is movably disposed in the movable groove, the sealing cover is rotatably connected to the support base, and the sealing cover is sealed to the panel through the sealing ring.

[0004] When in use, the sealing cap can only be automatically leveled by swinging the left and right ends and moving up and down, but the front and back ends cannot be swinged. During installation, deviations are unavoidable in the leveling structure, which cannot achieve automatic leveling and better sealing effect. In order to solve the above problems, an automatic leveling structure for sealing caps is proposed. Utility Model Content

[0005] The purpose of this invention is to provide an automatic leveling structure for sealing caps to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An automatic leveling structure for a sealing cap includes a panel. A sealing cap is disposed on the top of the panel. Connecting ears are symmetrically fixedly connected to both ends of one side of the sealing cap. A support base is disposed between the connecting ears. A first shoulder screw is passed through the connecting ears and is fixedly connected to the support base. The smooth surface of the first shoulder screw is rotatably connected to the connecting ear. A mounting groove is opened at the top of the panel directly below the support base. A rotating strip is movably disposed in the mounting groove. A connecting sleeve is fixedly installed at the top of the panel on one side of the rotating strip. A connecting pin passes through the connecting sleeve. The end of the connecting pin is fixedly connected to the side wall of the rotating strip and is rotatably connected to the connecting sleeve. A sliding groove is opened at the top of the rotating strip. The bottom of the support base is engaged in the sliding groove of the rotating strip and is slidably connected to the sliding groove. Countersunk holes are symmetrically opened on the support base. A second shoulder screw is passed through the countersunk hole. The bottom end of the second shoulder screw passes through the support base to the sliding groove of the rotating strip and is fixedly connected to the rotating strip.

[0008] As a further embodiment of this utility model: an annular groove is provided on the outer side of the opening at the top of the panel, and a sealing ring is provided in the annular groove.

[0009] As a further improvement of this utility model: a groove is provided between the connecting ears on the bottom side of the sealing cover near the bracket seat.

[0010] As a further improvement of this utility model, the length of the groove is greater than the length of the rotating bar.

[0011] As a further improvement of this utility model: the top of the sealing cover has an observation port, tempered glass is installed inside the observation port, and a fixing ring is set above the tempered glass inside the observation port. Multiple bolts are evenly arranged around the circumference of the fixing ring, and the bolts pass through the fixing ring and are fixedly connected to the sealing cover.

[0012] As a further improvement of this utility model, a rubber ring is fixedly connected to the bottom of the fixing ring.

[0013] As a further improvement of this utility model, a handle is fixedly connected to the top of the sealing cover on the side away from the support base.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. When this utility model is used, when it is attracted by an external force, the entire sealing cover will squeeze the sealing ring and sink down. Both ends of the sealing cover will sink normally, and the bracket will move with the sealing cover in the groove opened in the rotating strip. Under the action of the force transmitted by the sealing cover, the bracket will carry the rotating strip under the joint action of the connecting pin and the connecting sleeve to rotate in the installation groove, so that the sealing cover can be leveled more flexibly and achieve a better sealing effect.

[0016] 2. In use, this utility model allows workers to easily observe the stirring status of the stirring device through the observation port. The tempered glass prevents the mixture from splashing out, and if the tempered glass is damaged, the fixing ring can be removed from the sealing cover by loosening the bolts on the fixing ring, making it easy to replace the tempered glass.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-3In this embodiment of the present invention, an automatic leveling structure for a sealing cap includes a panel 1. A sealing cap 2 is disposed on the top of the panel 1. An annular groove 17 is formed on the outer side of the opening at the top of the panel 1, and a sealing ring 18 is disposed in the annular groove 17. The sealing ring 18 increases the sealing performance between the sealing cap 2 and the panel 1. Connecting ears 7 are symmetrically fixedly connected to both ends of one side of the sealing cap 2. A bracket seat 9 is disposed between the connecting ears 7. A first shoulder screw 8 is disposed through the connecting ears 7 and is fixedly connected to the bracket seat 9. The smooth surface of the first shoulder screw 8 is rotatably connected to the connecting ears 7. An installation groove 12 is formed at the top of the panel 1 directly below the bracket seat 9. A rotating strip 13 is movably disposed in the installation groove 12. A connecting sleeve 10 is fixedly installed at the top of the panel 1 on one side of the rotating strip 13. A connecting pin 11 is disposed through the connecting sleeve 10. The end of the connecting pin 11 is fixedly connected to the side wall of the rotating bar 13, and the connecting pin 11 is rotatably connected to the connecting sleeve 10. The top of the rotating bar 13 is provided with a sliding groove 14. The bottom of the bracket seat 9 is engaged in the sliding groove 14 of the rotating bar 13, and the bracket seat 9 is slidably connected to the sliding groove 14. The bracket seat 9 is symmetrically provided with countersunk holes 20. A second shoulder screw 19 is provided through the countersunk hole 20. The bottom end of the second shoulder screw 19 passes through the bracket seat 9 to the sliding groove 14 of the rotating bar 13, and the second shoulder screw 19 is fixedly connected to the rotating bar 13. The upward movement of the bracket seat 9 is the distance from the bottom of the countersunk hole 20 to the bottom of the cap of the second shoulder screw 19. The downward movement of the bracket seat 9 is the distance from the bottom of the bracket seat 9 to the bottom of the inner wall of the sliding groove 14. The rotation range of the rotating bar 13 is the range when both ends of the rotating bar 13 contact the bottom of the mounting groove 12.

[0023] When this utility model is installed on the equipment, when the sealing cover 2 is closed, when it is attracted by an external force, the entire sealing cover 2 will press the sealing ring 18 and sink. The two ends of the sealing cover 2 will sink normally. This is because the bracket 9 will move with the sealing cover 2 in the sliding groove 14 opened in the rotating bar 13. Under the action of force, the bracket 9 will carry the rotating bar 13, which is under the joint action of the connecting pin 11 and the connecting sleeve 10, to rotate in the mounting groove 12, so that the sealing cover 2 can be leveled more flexibly. Similarly, when it is not attracted by an external force, the entire sealing cover 2 will rise normally, and the rising distance is the same as the falling distance.

[0024] The bottom of the sealing cover 2 is provided with a groove 16 between the connecting ears 7 on the side near the bracket base 9. The length of the groove 16 is greater than the length of the rotating bar 13. The groove 16 is provided to avoid interfering with the rotation of the rotating bar 13.

[0025] The sealing cover 2 has an observation port 5 at its top, and a tempered glass 6 is installed inside the observation port 5. A fixing ring 4 is set above the tempered glass 6 inside the observation port 5. Multiple bolts are evenly arranged around the circumference of the fixing ring 4. The bolts pass through the fixing ring 4 and are fixedly connected to the sealing cover 2. During use, the operator can easily observe the stirring status of the stirring device through the observation port 5. The tempered glass 6 prevents the mixture from splashing out. When the tempered glass 6 is damaged, the fixing ring 4 can be removed from the sealing cover 2 by loosening the bolts on the fixing ring 4, making it easy to replace the tempered glass 6.

[0026] A rubber ring 15 is fixedly connected to the bottom of the fixing ring 4. The rubber ring 15 isolates the fixing ring 4 from the installed tempered glass 6, thereby protecting the tempered glass 6.

[0027] A handle 3 is fixedly connected to the top of the sealing cover 2 on the side away from the bracket 9, allowing the user to easily open the sealing cover 2 using the handle 3.

[0028] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
