DETAILED DESCRIPTION

[0017] The technical solution is now further described in conjunction with the drawings in the above specification, and the specific description is as follows: In this embodiment, directional words such as top and bottom are only for the convenience of description and are not intended to limit it.

[0018] See Figures 1 to 4As shown, a bulb structure with an adjustable angle of a lamp holder includes a lamp holder 2 and a lampshade 1, and a light source board is arranged in the lampshade. In this embodiment, the light source board is a conventional structure of the prior art, so it is not described in detail, and in actual application, the inner wall of the bottom surface of the lampshade is provided with a mounting ring groove 9 for the light source board and the light-transmitting surface cover. The light source board and the light-transmitting surface cover can be installed after installation. An arc-shaped opening 3 is provided on the top of the lampshade 1, and a locking boss 4 is integrally formed on the symmetrical inner wall of the lamp holder. The two locking bosses are located on both sides of the arc-shaped opening. In this embodiment, the distance between the locking bosses is less than the width of the arc-shaped opening, and in actual application, the lamp holder, the lampshade and the light source board arranged in the lampshade are all plastic structures.

[0019] The middle of the positioning boss is provided with a mounting cavity 5. The lamp holder seat 2 includes a swinging sphere 21 and a lamp holder connection threaded hole 22 at the top of the swinging sphere. A wire through hole 23 is provided at the center of the threaded hole connecting the swinging sphere and the lamp holder. A plane 24 is provided on the symmetrical side of the swinging sphere. In actual application, the distance between the two planes on the swinging sphere is the same as the distance between the two positioning bosses. A magnet positioning hole 25 is provided at the center of the plane. A magnet 27 is provided in the magnet positioning hole through a fixed iron sleeve 26. An iron piece 28 is movably provided in the mounting cavity.

[0020] In this embodiment, the position of the magnet positioning hole and the installation cavity are matched. After installation, the two planes are respectively pressed and connected with the two locking bosses. At the same time, the iron piece is sucked out of the installation cavity by the action of the magnet to connect the limit, so that the lampshade and the swinging sphere in the lamp holder are connected together. The magnet is in a fixed iron sleeve, which can protect the magnet from being fragile and enhance the resistance of the magnet, so as to achieve the effect of using a smaller magnet to generate greater resistance. In addition, since the lampshade and the swinging sphere generate resistance through magnetic attraction, the relative rotation between the two must overcome the magnetic attraction force, and the magnetic attraction force is constant, so the force used to rotate the swinging sphere to each position can be regarded as constant. As long as the magnetic force does not disappear, the force used by the swinging sphere is the same no matter how many times it rotates. Therefore, the overall structure is more stable, which is conducive to improving the service life, and will not affect the angle adjustment operation, and it is highly practical.

[0021] The installation cavity and the magnet positioning hole both include a central circular hole 6 and at least one limiting slot 7 on the side wall of the central circular hole. The fixed iron sleeve 26 includes a torus 261 and a convex strip 262 integrally formed on the outer side of the torus. The magnet is cylindrical and is positioned in the torus, and limiting protrusions 8 are integrally formed at both ends of the iron piece. The convex strip of the fixed iron sleeve and the limiting protrusion of the iron piece are inserted into the limiting slot for limiting.

[0022] In actual application, in order to prevent the lamp holder from falling off from the lampshade, the diameter of the swinging sphere is smaller than the width of the arc-shaped opening. Since the diameter of the swinging sphere is smaller than the width of the arc-shaped opening, the swinging sphere will not fall off from the arc-shaped opening after installation. At the same time, the length of the arc-shaped opening is larger than the diameter of the lamp holder connecting threaded hole, so that the angle adjustment can be achieved, and the lamp holder connecting threaded hole can be moved in the arc-shaped opening. During installation, the lamp holder is inserted from the bottom of the lampshade, the swinging sphere is buckled between the two locking bosses, and the magnet is magnetically connected to the iron piece to limit the position, and the lamp holder connecting threaded hole extends out of the arc-shaped opening.

[0023] The installation principle is briefly described as follows: During installation, insert the lamp holder from the bottom of the lampshade and move upward so that the plane of the swinging sphere is buckled between the positioning bosses. The magnet in the swinging sphere sucks out the left and right iron parts of the lampshade through magnetic force, so that the speaker cover and the top swinging sphere are connected together by pins. A fixed iron sleeve is installed in the swinging sphere to protect the magnet from being fragile and enhance the resistance of the magnet, so as to achieve greater resistance with a smaller magnet. The left and right iron parts of the lampshade have convex columns to prevent the iron parts from rotating when the swinging sphere rotates, thereby fixing the pins. Since the lampshade and the swinging sphere generate resistance through magnetic attraction, the relative rotation between the two must overcome the magnetic attraction force, and the magnetic attraction force is constant, so the force used by the swinging sphere to rotate to each position can be regarded as constant. As long as the magnetic force does not disappear, the force used by the swinging sphere is the same no matter how many times it rotates. Therefore, this structure is stable, has a long service life, and is highly applicable.

[0024] The utility model has reasonable structural arrangement and a more stable overall structure, which is beneficial to improving the service life and will not affect the angle adjustment operation. The utility model is stable and reliable to use and has strong practicality.

[0025] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification can also be directly processed according to existing technical common sense. At the same time, the connection method of each component adopts the mature conventional means in the prior art, and the machinery, parts and equipment all adopt the conventional models in the prior art, so no specific description will be given here.

[0026] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, and are not intended to limit the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. However, these obvious changes or modifications derived from the essential spirit of the present invention still belong to the protection scope of the present invention.
