Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0022] As Figures 1 to 3 shown, the present utility model provides a projection lamp angle adjustment device, including a projection lamp 1 and an angle adjustment base 2. The angle adjustment base 2 includes a base 21 connected to the bottom of the projection lamp 1, a positioning sleeve 22, an adjustment positioning component 23, and a connecting rod 24. The adjustment positioning component 23 is encapsulated between the base 21 and the positioning sleeve 22. The projection lamp 1 is connected to the adjustment positioning component 23 through the connecting rod 24. One end of the adjustment positioning component 23 abuts against the base 21, and the other end of the adjustment positioning component 23 abuts against the positioning sleeve 22;

[0023] The adjustment positioning component 23 includes an adjustment positioning shaft 231 movably installed between the base 21 and the positioning sleeve 22. A positioning block 232 is provided on the outer surface of the adjustment positioning shaft 231 close to the positioning sleeve 22. The positioning block 232 abuts against the inner wall of the positioning sleeve 22; due to the setting of the positioning block 232, under the elastic force of the positioning spring 215, the positioning block 232 can be firmly inserted into the anti-slip sleeve 223, so that the adjustment positioning shaft 231 cannot rotate, thereby achieving the effect of preventing the angle of the projection lamp 1 from changing due to accidental collision.

[0024] Among them, the base 21 includes a fixed seat 211 connected to the bottom of the positioning sleeve 22. A positioning cavity 212 is opened at the top of the fixed seat 211. A bolt is provided inside the positioning cavity 212. The fixed seat 211 is fixedly installed through the bolt inside the positioning cavity 212.

[0025] Among them, a connecting ring 213 is provided at the top of the fixed seat 211 outside the positioning cavity 212. The positioning sleeve 22 is fixedly connected to the fixed seat 211 through the connecting ring 213.

[0026] Among them, a positioning pressure ring 214 is arranged inside the positioning cavity 212. The top of the positioning pressure ring 214 is in movable contact with the outer surface of the adjusting positioning shaft 231. A positioning spring 215 is arranged inside the positioning cavity 212 at the bottom of the positioning pressure ring 214. The positioning spring 215 is conical. The lower end of the positioning spring 215 abuts against the bottom of the inner cavity of the positioning cavity 212, and the upper end of the positioning spring 215 is connected to the bottom of the positioning pressure ring 214;

[0027] The top and bottom of the adjusting positioning shaft 231 are both arc surfaces. The top arc surface of the adjusting positioning shaft 231 contacts the positioning sleeve 22, and the bottom arc surface of the adjusting positioning shaft 231 contacts the positioning pressure ring 214; due to the arc-shaped structure at the bottom of the adjusting positioning shaft 231, it is not only convenient for stable abutment with the positioning pressure ring 214, but also when the swing projection lamp 1 changes its angle, the positioning spring 215 can always stably press the adjusting positioning shaft 231 through the positioning pressure ring 214, so that the positioning block 232 at its top is inserted into the anti-slip sleeve 223.

[0028] Among them, the positioning sleeve 22 includes a press-fitting ring 221 connected to the top of the fixed seat 211. The press-fitting ring 221 is fixedly connected to the fixed seat 211 through a connecting ring 213. A through hole 222 is opened at the top of the press-fitting ring 221;

[0029] The bottom of the press-fitting ring 221 is an arc-shaped cavity, and the arc-shaped cavity is communicated with the through hole 222. The connecting rod 24 is arranged inside the through hole 222.

[0030] Among them, an anti-slip sleeve 223 is fixedly attached inside the arc-shaped cavity at the bottom of the press-fitting ring 221. The bottom of the anti-slip sleeve 223 is adapted to the top arc of the adjusting positioning shaft 231. The bottom of the anti-slip sleeve 223 contacts the top of the adjusting positioning shaft 231. The positioning block 232 at the top of the adjusting positioning shaft 231 is inserted into the anti-slip sleeve 223; due to the setting of the anti-slip sleeve 223, the movement of the positioning block 232 can be restricted, thereby restricting the accidental movement of the adjusting positioning shaft 231 to prevent the accidental change of the angle of the projection lamp 1; and because the anti-slip sleeve 223 is made of rubber structure and has elasticity, when it expands, under the elastic force of the anti-slip sleeve 223, through the adjusting positioning shaft 231, the connecting rod 24, etc., it can provide buffering for the impact of the projection lamp 1, achieving the effect of reducing the intensity of collision damage.

[0031] The working principle and usage process of the present utility model:

[0032] Fix the fixed seat 211 through bolts, then connect the press-fitting ring 221 to the fixed seat 211 through the connecting ring 213, and press-fit the adjusting positioning shaft 231, the positioning spring 215, etc. into the positioning cavity 212 between the fixed seat 211 and the press-fitting ring 221. Finally, fixedly connect the projection lamp 1 to the connecting rod 24 to complete the installation;

[0033] When it is necessary to adjust the angle of the projection lamp 1, first press the connecting rod 24 through the projection lamp 1, which can push the adjusting positioning shaft 231 to move downward, and then the adjusting positioning shaft 231 moves downward along the inside of the positioning cavity 212. Since the movement of the adjusting positioning shaft 231 can cause the positioning block 232 on its surface to disengage from the anti-slip sleeve 223, and at the same time, under the cooperation of the positioning pressing ring 214, the positioning spring 215 is compressed to increase the recovery strength of its elastic force. At this time, rotating the projection lamp 1 can drive the connecting rod 24, the adjusting positioning shaft 231 and the positioning block 232 on its surface to move, so as to adjust the angle of the projection lamp 1;

[0034] During daily use, when the projection lamp 1 is accidentally touched, since the positioning block 232 is inserted into the inside of the anti-slip sleeve 223, its movement is restricted, which can prevent the adjusting positioning shaft 231 from moving, thus preventing the situation of accidentally changing the angle of the projection lamp 1.

[0035] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device.
