Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present.

Examples

Referring to fig. 1 to 4, the adjusting bolt assembly of the present embodiment includes a worm 10, a threaded sleeve 20, an expansion member 30, a first bevel gear 40, and a second bevel gear 50.

Referring to fig. 1, the worm 10 is made of metal or hard plastic, has high strength, and cannot be easily bent after being subjected to surface smoothing;

further, an annular body is fixed on the outside of one end of the worm 10, a threaded sleeve 20 is sleeved on the outside of one end of the worm 10, the threaded sleeve 20 is tightly attached to the annular body, and specifically, the threaded sleeve 20 and the worm 10 are in interference fit.

Referring to fig. 2 and 3, an expansion member 30 is detachably fixed to the outside of one end of the worm 10 close to the threaded sleeve 20; in particular, the expansion element 30 is snap-fitted to the worm 10, so as to increase the sealing effect.

Referring to fig. 3, further, the exterior of the expansion member 30 is connected to the first bevel gear 40 by snap fit, and the second bevel gear 50 is located above the worm 10 and is engaged with the first bevel gear 40 to form a bevel gear structure.

Furthermore, the buckles are all inner buckles which are not disassembled after being assembled so as to ensure the characteristic of assembly tightness,

wherein, the thread bush 20 is made of rubber; the material of the expansion piece 30 is plastic; and after the threaded sleeve 20 and the expansion piece 30 form interference fit outside the worm 10, the clearance can be eliminated, and the sealing effect is achieved.

When the lamp is used, in the scheme, when the worm 10 needs to have the adjusting function, the second bevel gear 50 is used as a force application part, the worm 10 is driven to rotate by means of the meshing of the second bevel gear 50 and the first bevel gear 40, so that the lamp is adjusted, the axial force application direction of the worm 10 is changed into the radial force application direction by adding the bevel gear structure formed by meshing the first bevel gear 40 and the second bevel gear 50, and the installation and adjustment are facilitated by adjusting the force application position; the product utilizes the interference fit formed by the expansion piece 30 and the threaded sleeve 20 at the outer side of the end of the worm 10 to achieve the sealing effect.
