[0009] A second worm is rotatably connected inside the mounting base, and the second worm is meshingly connected with a second worm wheel. The second worm wheel is welded to the bottom of the chassis as a whole via a shaft that runs through the axis center thereof.

[0010] Further preferably, the surfaces of the fixing ring and the adjusting ring are respectively provided with threaded grooves, and the fixing ring and the adjusting ring are connected by bolts, and the adjusting ring forms an elastic reset structure through a spring, and the adjusting ring slides and retracts in the cavity on one side of the fixing ring through the spring.

DETAILED DESCRIPTION

[0026] The mounting frame assembly 2 is welded between the brackets 1 through the fixing ring 201 provided thereon. An adjusting ring 202 is provided on one side of the fixing ring 201 . A spring 203 is welded at one end of the adjusting ring 202 . One end of the spring 203 is welded to the inside of the fixing ring 201 .

[0027] The dust cover 3 includes an outer frame 301 and an inner frame 302. The bottom of the outer frame 301 is glued to the edge of the top of the fixing ring 201. The inner wall of the outer frame 301 is provided with a track 303. The inner frame 302 is slidably connected to the track 303 through a slider provided thereon.

[0028] The first worm 601 and the first worm wheel 602 are rotatably connected inside the chassis 6. The first worm 601 is meshedly connected to one side of the first worm wheel 602. A bevel gear 603 is provided above the first worm wheel 602, and the bevel gear 603 is meshedly connected to the bottom of the bevel gear 5.

[0029] A second worm 701 is rotatably connected inside the mounting base 7 , and a second worm wheel 702 is meshingly connected to the second worm 701 . The second worm wheel 702 is welded to the bottom of the chassis 6 via a shaft that runs through the axis center thereof.

[0030] In this embodiment, Figure 3As shown, the surfaces of the fixing ring 201 and the adjusting ring 202 are respectively provided with thread grooves, and the fixing ring 201 and the adjusting ring 202 are connected by bolts, and the adjusting ring 202 forms an elastic reset structure through the spring 203, and the adjusting ring 202 slides and retracts in the cavity on one side of the fixing ring 201 through the spring 203; currently, many projector bodies 4 and the mounting frames fixing them are mostly integrated, and when the projector body 4 fails, it needs to be disassembled as a whole, which will cause inconvenience. By adding the mounting frame assembly 2, the projector body 4 and the mounting base 7 fixed to the wall are made into a split structure, and the elastic telescopic structure of the fixing ring 201 and the adjusting ring 202 makes the projector body 4 have good compatibility and convenience during the installation process.

[0031] In this embodiment, Figure 2 As shown, the top and the middle of the outer frame 301 and the inner frame 302 are respectively hollowed out, and the outer frame 301 and the inner frame 302 are respectively provided with protective plates made of tempered glass at the hollowed out parts, and the outer frame 301 and the inner frame 302 are respectively connected by bolts through threaded grooves opened on their surfaces, and the outer frame 301 is attached to and slidably connected to the inner wall of the outer frame 301; by adding the dust cover 3, the surface of the projector body 4 can be effectively protected from the influence of the external environment such as dust, water vapor, etc., so as to effectively avoid such pollutants from entering the interior of the projector body 4 and causing damage to its internal optical elements. At the same time, the sliding opening and closing structure presented by the outer frame 301 and the inner frame 302 allows it to be easily opened and closed while providing protection, so that maintenance personnel can inspect, clean or maintain the internal projector body 4 conveniently, which helps to reduce maintenance time and cost and improve the availability of the equipment.

[0032] In this embodiment, Figure 4 As shown, the bevel gears 603 are horizontally distributed, and the axis point of the first worm gear 602 is located on the vertical line of the midpoint between the bevel gears 603, and the first worm gear 602 and the bevel gear 603 respectively form a transmission structure through a belt 604 running through the surface of the shaft at its axis; by adding two sets of bevel gears 603, a stable support is provided for the subsequent bracket 1 to drive the projector body 4 to rotate.

[0033] In this embodiment, Figure 3 and Figure 4As shown, the bevel gears 5 are respectively perpendicular to the surfaces of the bevel gears 603, and the bevel gears 5 form a transmission structure through the bevel gears 603; when the first worm 601 is driven by the servo motor, the first worm wheel 602 rotates, and the rotation of the first worm wheel 602 causes the shaft at its axis to drive the bevel gears 603 on both sides to rotate simultaneously through the belt 604, thereby driving the transmission of the upper bevel gear 5. Through the transmission structure of the bevel gear 5 in the vertical direction along the bevel gear 603, the bracket 1 drives the internal projector body 4 to be tilted 180° in the vertical direction. In some specific industrial environments, it is necessary to project warning signals to positions of different heights to ensure that all personnel can see them. The vertical tilt adjustment can meet this requirement, so that the projector body 4 can adapt to work scenes of different heights, thereby enhancing the applicability and practicality of the warning signal, which helps to ensure that each work area can be adequately warned and protected, thereby reducing the occurrence of accidents.

[0034] In this embodiment, Figure 1 and Figure 5 As shown, the second worm gear 702 forms a rotating structure inside the mounting base 7 through the second worm 701, and the chassis 6 forms a rotating structure on the surface of the mounting base 7 through the second worm gear 702, and a plurality of mounting through holes are opened at the bottom of the mounting base 7; the chassis 6 is rotated in the horizontal direction through the transmission structure of the second worm gear 702 through the second worm 701, and then the projector body 4 can rotate 360° in the horizontal direction, so that it can cover all directions on the entire horizontal plane, which can ensure that the warning signal can be seen in different directions, thereby enhancing the effectiveness and visibility of the warning.

[0035] The use method and advantages of the utility model: The road sign projector which is easy to adjust at multiple angles, when in use, has the following working process:

[0036] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, it should be noted that the projector body 4 contains a light source system inside, and it is an electrically connected control subject to the outside. The control system is used to control the operation of the light source, optical components and projection device. The control subject will change the icon that the projector body 4 needs to project according to the visual system electrically connected to the light source system inside it. It is a prior art. When the device is in use, it is fixed to a fixed wall or top surface of an industrial plant through the mounting through hole at the bottom of the mounting base 7. When it is necessary to adjust the projection range of the projector body 4, the servo motor drives the second worm 701 to engage the second worm wheel 702 to rotate, and the chassis 6 connected coaxially will rotate horizontally along the surface of the mounting base 7 accordingly, thereby achieving the projector body 4 can rotate 360° in the horizontal direction, and when the servo motor drives the first worm 601 to rotate, the first worm wheel 602 engaged on one side thereof rotates accordingly, and the belt 6 on the surface of the shaft at the axis of the first worm wheel 602 is 04, the bevel gears 603 on both sides rotate accordingly, and then the conical gear 5 is transmitted in the vertical direction along the surface of the bevel gear 603, so that the projector body 4 can be tilted 180° in the vertical direction. Through the electrical connection between the external control system and the servo motor, the projector body 4 can cover multiple surface areas from different heights and angles, ensuring that the warning signal can be seen in different directions, thereby enhancing the effectiveness and visibility of the warning. At the same time, when maintenance or disassembly is required, the bolts on the surface of the outer frame 301 and the inner frame 302 are removed in advance, and the inner frame 302 is slid toward the inner wall of the outer frame 301 to open the channel for maintaining the projector body 4. If the projector body 4 needs to be disassembled as a whole, after the bolts on the surface of the fixing ring 201 and the adjusting ring 202 are removed, under the elastic structure of the spring 203, one end of the adjusting ring 202 will be reset and slide to the inner cavity of the fixing ring 201, reserving a larger operating space for taking the projector body 4.

[0037] The above shows and describes the basic principle, main features and advantages of the utility model. Technical staff in this industry should understand that the utility model is not limited by the above embodiments.
