[0030] Specifically, the first steering structure 30 and the second steering structure 40 both use a gear transmission device and a reset fixing device to achieve the purpose of rotating and fixing the lamp body 10. The gear transmission device can effectively transmit thrust and rotational motion. When the gear rotates to the required position, the reset fixing device is used to reset the gear to fix it, so as to achieve the effect of precise control and positioning of the rotation. The gear transmission device and the reset fixing device (such as a spring) are both mechanical systems with simple structures, good stability and reliability, and long service life. Compared with other steering structures currently available on the market, such as: universal joint steering structure, the combination of the gear transmission device and the reset fixing device is more reliable in position fixation; the sliding bearing structure, the combination of the gear transmission device and the reset fixing device is simpler in structure and has strong feasibility; the hydraulic steering structure and the electric steering structure, the combination of the gear transmission device and the reset fixing device has a lower cost and is more suitable for people's daily use.

[0031] Specifically, the L-shaped lamp arm 50 can provide users with a better holding and operating experience, making it easier for users to control and adjust the light output direction and angle of the spotlight, thereby increasing convenience and comfort of use.

[0032] Compared with the prior art, the spotlight proposed in this embodiment has the first steering structure 30 that realizes the free rotation of the spotlight around the vertical axis through a gear transmission device and the fixation of the rotation position of the spotlight through a reset fixing device, and the second steering structure 40 that realizes the free rotation of the spotlight around the horizontal axis through a gear transmission device and the fixation of the rotation position of the spotlight through a reset fixing device. The spotlight combines the first steering structure 30 and the second steering structure 40 to realize the rotation and fixation of the lamp body around the vertical axis and around the horizontal axis, so that the illumination range of the spotlight light is larger, the angle adjustment range is wider, and a more flexible and accurate light adjustment effect is achieved, and the user experience is better.

[0034] When the lamp body 10 rotates around its own vertical axis due to thrust, the rotating lamp body 10 drives the lamp arm 50 to rotate, and the rotating lamp arm 50 drives the first machine tooth 302 to rotate through the mutual cooperation of the upper tooth pattern 501 and the lower tooth pattern, and the rotating first machine tooth 302 stretches the first spring 303; when the lamp arm 50 is stationary because the lamp body 10 is not subjected to thrust, the stationary lamp arm 50 releases the first machine tooth 302 through the mutual engagement of the upper tooth pattern 501 and the lower tooth pattern, and the released first machine tooth 302 causes the first spring 303 to reset and be resisted by the reset first spring 303.

[0035] Specifically, the first steering structure 30 includes a first screw 301, a first gear 302, a first spring 303 and a first nut 304. The first screw 301 and the first nut 304 are used for fixed connection, the first gear 302 is used to receive the thrust from the lamp arm 50 and control the rotation direction, and the first spring 303 is used to provide fixed support. These components cooperate with each other to realize the rotation fixing function of the first steering structure 30. The first steering structure 30 can be used to allow the lamp body 10 to be rotated and fixed around the vertical axis, thereby adjusting the horizontal position of the lamp body 10 to adjust the lighting range and angle to meet different lighting needs.

[0036] Specifically, a first washer 305 may be provided between the first screw rod 301 and the lamp arm 50. By selecting the first washer 305 of appropriate thickness, the gap between the first screw rod 301 and the lamp arm 50 may be adjusted to achieve an optimal matching state, thereby improving the stability and precision of the first steering structure 30.

[0037] In some embodiments of the present application, the first machine tooth 302 is a hollow cylinder, and at least one protrusion and at least one recess are disposed on the outer side of the hollow cylinder.

[0038] Specifically, the first machine tooth 302 can effectively prevent the first spring 303 from sliding or falling off by providing a protrusion, thereby ensuring the stability and safety of the first steering structure 30. In addition, the protrusion can also serve as a reinforcing rib to increase the structural strength and stability of the hollow cylinder, thereby improving the durability and service life of the first machine tooth 302. The first machine tooth 302 can improve the comfort of holding by providing a pit, making it more convenient for the user to install, adjust or move the first machine tooth 302, thereby improving installation efficiency and convenience.

[0039] In some embodiments of the present application, the second steering structure 40 includes a second screw rod 401, a second spring 402, a second machine tooth 403 and a second nut 404; wherein, the top of the lamp arm 50 is provided with a second screw hole for passing through the second screw rod 401 and a second installation position for installing the second spring 402, and the lamp body 10 is provided with a second through hole for passing through the second screw rod 401, and the outer periphery of the second through hole is provided with an outer tooth pattern on a side facing the stud head of the second screw rod 401, and the second machine tooth 403 is provided with an inner tooth pattern on a side facing the thread tip of the second screw rod 401, and the outer tooth pattern and the inner tooth pattern are engaged with each other, and the second machine tooth 403 is fixedly connected to the second spring 402 on a side facing the stud head of the second screw rod 401, and the second spring 402 is provided at the second installation position, and the second screw rod 401 passes through the second spring 402, the second machine tooth 403, the second screw hole and the second through hole in sequence, and is fixedly connected to the lamp body 10 through the second nut 404;

[0040] When the lamp body 10 rotates around its own horizontal axis due to thrust, the rotating lamp body 10 drives the second machine teeth 403 to rotate through the mutual cooperation of the outer tooth pattern and the inner tooth pattern, and the rotating second machine teeth 403 stretch the second spring 402; when the lamp body 10 is stationary due to no thrust, the stationary lamp body 10 releases the second machine teeth 403 through the mutual engagement of the outer tooth pattern and the inner tooth pattern, and the released second machine teeth 403 cause the second spring 402 to reset and be resisted by the reset second spring 402.

[0041] Specifically, the second steering structure 40 includes a second screw 401, a second machine tooth 403, a second spring 402 and a second nut 404. The second screw 401 and the second nut 404 are used for fixed connection, the second machine tooth 403 is used to receive the thrust from the lamp body 10 and control the rotation direction, and the second spring 402 is used to provide fixed support. These components cooperate with each other to realize the rotation fixing function of the second steering structure 40. The second steering structure 40 can be used to allow the lamp body 10 to be rotated and fixed around the horizontal axis, thereby adjusting the vertical position of the lamp body 10 to adjust the lighting range and angle to meet different lighting needs.

[0042] Specifically, the relative positions of the second machine teeth 403 and the second spring 402 in the second steering structure 40 are opposite to the relative positions of the first machine teeth 302 and the first spring 303 in the first steering structure 30. It can be seen that in actual application, the structural forms of the gear transmission device and the reset fixing device adopted by the first steering structure 30 and the second steering structure 40 can be adjusted accordingly according to the structural characteristics of the lamp body 10, the lamp holder 20 and the lamp arm 50 of the spotlight, as long as the effect of rotating and fixing the lamp body 10 can be achieved. For example, corresponding to the second steering structure 40, the stretching degree and strength of the second spring 402 can be changed by adjusting the elastic coefficient of the second spring 402, thereby affecting the rotation speed and damping effect of the lamp body 10; the shape and size of the second machine teeth 403 can also be adjusted to affect the bite degree and rotation effect of the machine teeth and the external tooth pattern; the shape and number of the external tooth pattern and the inner tooth pattern can be changed to adjust the bite degree and rotation stability between them; the length of the second screw 401 can be adjusted to change the distance between the parts, thereby affecting the range and flexibility of rotation; finally, the design and material of the second nut 404 can be adjusted to affect the friction and fixing effect between the second nut 404 and the second screw 401. In actual application, by adjusting these parts, the spotlight can not only achieve the purpose of rotation and fixation, but also can be customized according to the specific application scenario to meet the needs of various specific occasions. Of course, the above adjustment method is also applicable to the first steering structure 30, and no further examples are given here.

[0043] Specifically, a second washer 405 may be further provided between the second screw 401 and the lamp arm 50. The second washer 405 may help disperse the pressure exerted by the second screw 401 on the lamp arm 50, reduce local pressure concentration, and thus reduce the risk of wear and deformation of the second steering structure 40. The second washer 405 may also reduce the friction between the second screw 401 and the lamp arm 50, reduce the friction coefficient, and make the second screw 401 rotate more smoothly, thereby extending the service life.

[0044] In some embodiments of the present application, the second machine tooth 403 is a hollow cylinder, and the outer side of the hollow cylinder is provided with at least one protrusion and at least one pit.

[0045] In some embodiments of the present application, two grooves are disposed on the inner side of the lamp arm 50 .

[0046] Specifically, the two grooves provided on the inner side of the lamp arm 50 can increase the friction of the lamp arm 50, so that the user can hold the lamp arm 50 more firmly, avoid slipping or loss of control, and improve the safety and stability of operation. The two grooves can also provide a better grip, making it easier for the operator to control and rotate the lamp arm 50, thereby improving the accuracy and comfort of the rotation operation of the lamp body 10.

[0047] In some embodiments of the present application, the lamp holder 20 is a frustum, and two or four screw holes 201 are correspondingly arranged on the side of the frustum.

[0048] Specifically, the lamp holder 20 is provided with two or four screw holes 201, which is conducive to the stable installation of the spotlight. By fixing with screws, the lamp holder 20 can be ensured to be firmly installed in the required position, avoiding the shaking of the lamp holder 20, and improving the overall safety and stability of the spotlight.

[0049] In some embodiments of the present application, the spotlight further includes a pointed cone 60, and the wide portion of the pointed cone 60 is detachably connected to the bottom of the frustum.

[0050] Specifically, the pointed cone 60 is also called a ground rod, which is detachably connected to the lamp holder 20. When necessary, the spotlight can be installed with a ground rod at the bottom of the lamp holder 20, so that the spotlight can be more easily inserted into the soil or other soft ground to be installed in outdoor places such as gardens and lawns, thereby increasing the flexibility and applicability of the spotlight and providing a wider lighting range.

[0051] In some embodiments of the present application, the spotlight further includes a power input line 70 , and a plug 80 is disposed at the bottom of the lamp body 10 , and the power input line 70 and the plug 80 are detachably connected.

[0052] Specifically, the power input line 70 and the plug 80 are detachably connected, which is convenient for the user to install and maintain. The user can easily connect or disconnect the power input line 70 and the plug 80, making the installation and replacement of the spotlight more convenient and flexible.

[0053] In some embodiments of the present application, the spotlight further includes a 5W LED lamp, and the LED lamp is electrically connected to the plug 80 .

[0054] Specifically, LED lamps generally have higher energy efficiency and can convert electrical energy into light energy more efficiently than traditional bulbs. The use of LED lamps in the spotlights can effectively reduce energy consumption and improve energy-saving performance. At the same time, LED lamps have a long life and low power consumption, which can significantly reduce the frequency of bulb replacement and maintenance costs.

[0055] The spotlight provided in this embodiment can realize rotation fixation with two degrees of freedom, vertically and horizontally, greatly improving the adjustable range of light irradiation and angle, and has a simple structure and strong feasibility.

[0056] It should be noted that the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0057] The above description is only a partial or preferred embodiment of the present invention. Neither the text nor the drawings can limit the scope of protection of the present invention.
