Detailed Embodiments

[0021] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings and embodiments. It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the terms "bottom surface" and "top surface", "inner" and "outer" refer to the directions towards or away from the geometric center of a specific component respectively.

[0022] Such as Figures 1-5As shown in the figure, the present utility model provides a spot lamp with adjustable focal length, which includes a lamp body 2, a lamp head 1, a lens 4 and a ball plunger machine screw 3. The lens 4 is arranged inside the lamp head 1. The lamp body 2 is provided with a plurality of focusing grooves 14. The lamp head 1 is connected to the focusing grooves 14 through the ball plunger machine screw 3. The lamp head 1 moves relative to the lamp body 2 in the horizontal direction, and one focusing groove 14 corresponds to one focusing angle.

[0023] As an embodiment of the present utility model, the lamp body 2 is provided with a guide rail 13, and a plurality of the focusing grooves 14 are arranged in the guide rail 13. The ball plunger machine screw 3 moves in the horizontal direction along the guide rail 13.

[0024] As another embodiment of the present utility model, the lamp head 1 is provided with a mounting hole 12, and the ball plunger machine screw 3 is installed in the mounting hole 12.

[0025] As another embodiment of the present utility model, there are three focusing grooves 14, which respectively correspond to the focusing angles of 30°, 60° and 90°.

[0026] The spot lamp is divided into two parts: the lamp head 1 and the lamp body 2. The lamp is made of aluminum alloy material, with a long service life and environmental protection. The cylindrical lamp body 2 is convenient for the general domestic die-casting machine / CNC machining. The lamp body 2 and the middle light source bearing part have an integral bone position connection structure, with good heat dissipation. The lamp head 1 and the lamp body 2 are connected by means of setting the guide rail 13. An installation hole 12 is designed in the lamp head 1 to fixedly install the ball plunger machine screw 3. A concave guide rail 13 is designed in the lamp body 2, and a plurality of semi-circular focusing grooves 14 corresponding to the ball plunger machine screw 3 are designed inside the guide rail 13. When an external force is used to stretch the lamp head 1 outwards, the ball plunger machine screw 3 will sink inwards. When the position of the ball plunger machine screw 3 moves to the focusing groove 14, the ball will pop out and get stuck at the position of the focusing groove 14, thus forming a sense of jerk. And digital scale marks are also printed on the focusing groove 14, so that the user can clearly know the current focusing angle, making it more convenient and clear for the user to use. In the embodiment of the present utility model, there are three focusing grooves 14, which respectively correspond to the focusing angles of 30°, 60° and 90°.

[0027] As another embodiment of the present utility model, a silica gel sleeve 5 is sleeved outside the lens 4, and the silica gel sleeve 5 is clamped inside the lamp head 1.

[0028] As another embodiment of the present utility model, a pressing plate 6 for pressing the lens 4 is further arranged inside the lamp head 1, and the pressing plate 6 abuts against the silica gel sleeve 5.

[0029] As another embodiment of the utility model, it further includes a lamp board 7 , which is arranged inside the lamp body 2 , and is connected to a power module arranged inside the lamp body 2 .

[0030] As another embodiment of the utility model, it further comprises an O-ring 8, which is sleeved in a groove on the outer surface of the lamp body 2, and is disposed between the lamp body 2 and the lamp holder 1. The lamp body 2 is waterproofed by using a double-layered silica gel O-ring 8, and can be installed and used indoors and outdoors, with a wide range of uses and high cost performance.

[0031] As another embodiment of the present utility model, the tail end of the lamp body 2 is locked with the wire 9 by means of screws, and the wire 9 is connected to the power module.

[0032] As another embodiment of the utility model, it further comprises a bracket 10 , and two ends of the bracket 10 are respectively connected to mounting blocks 11 arranged on two sides of the lamp body 2 .

[0033] The lamp assembly process is as follows: the wire 9 is locked at the tail of the lamp body 2 through a waterproof screw and connected to the power module; the lamp board 7 is coated with thermal paste and then screwed inside the lamp body 2 and connected to the power module, and the power module provides power to the lamp board 7; the two O-rings 8 are inserted into the grooves specified in the lamp body 2; the lens 4 is covered with the silicone sleeve 5, placed inside the lamp head 1, and clamped by the structure inside the lamp head 1; the pressing plate 6 is rotated to press the lens 4; the lamp head 1 is lubricated with vaseline, and the lamp head 1 is inserted into the lamp body 2; the ball screw 3 is locked in the mounting hole 12 of the lamp head 1; the bracket 10 is installed on the mounting block 11 on the lamp body 2, and the locking screw is used. After the above steps are completed, the lamp assembly is completed.

[0034] When the lamp is in use, the lamp head 1 is pulled to move away from the lamp body 2, and the distance between the lens 4 and the lamp board 7 will change, causing the focusing angle to change. The bead-shaped screw 3 will move in the guide rail 13, and when encountering the focusing groove 14, the bead-shaped screw 3 will fall into the groove, giving the user an obvious sense of frustration. The user can know the current focusing angle by observing the numbers exposed on the lamp body 2. Continue to pull the lamp head 1. Due to the nature of the bead-shaped screw 3 itself, the bead-shaped screw 3 will break away from the focusing groove 14 and return to the guide rail 13, and move to the next focusing groove 14, thereby adjusting the focusing angle. The lamp head 1 and the lamp body 2 can reciprocate relative to each other, and the focusing angle can be repeatedly adjusted and tested to achieve the best light output effect.

[0035] Most spotlights on the market do not have accurate positioning points to correspond to the light-emitting angle and can only be evaluated by feeling. The structure of the present utility model adopts the cooperation of the guide rail 13 and the ball plunger machine screw 3. When the ball plunger machine screw 3 falls into the concave groove position, an obvious sense of jerk will be generated, enabling the user to more clearly understand what the current light-emitting angle is. The overall design of the lamp is novel, and the outer shape structure adopts a bevel structure design. The distance between the lamp head 1 and the lens 4 is relatively deep. When a person walks by, the light will not cause dizziness to the human eye due to the deep lamp head, playing a role in anti-glare. The lamp adopts a double-layer silicone ring waterproof structure and can be used both outdoors and indoors. It has stable and reliable performance and a wide range of applications.

[0036] The above content is a further detailed description of the present utility model in combination with specific preferred embodiments, and it cannot be determined that the specific implementation of the present utility model is only limited to these descriptions. For those of ordinary skill in the technical field to which the present utility model belongs, without departing from the concept of the present utility model, several simple deductions or substitutions can be made, and all should be regarded as belonging to the protection scope of the present utility model.
