Description
Technical Field
[0001] This utility model belongs to the field of mining lamp technology, and in particular relates to an explosion-proof LED mining lamp. Background Technology
[0002] Explosion-proof LED mining lamps are devices that provide lighting for miners. They are compact and can be installed on the buckle of a safety helmet to assist workers in lighting. Their sealed lamp body design ensures good explosion-proof safety, making them one of the important safety tools in mining operations.
[0003] Existing explosion-proof mining lamps include components such as mounting bases and lamp bodies. The mounting base and lamp body are an integrated structure. When mounted on a safety helmet, its angle can only move with the safety helmet and cannot be adjusted as needed. Miners need to frequently change positions underground (such as bending over, tilting their heads back, and turning to the side). Fixed-angle mining lamps cannot meet the lighting needs of different postures. Some products use fixing bolts and other components to achieve the purpose of angle adjustment, but this adjustment method relies on both hands to operate. It requires both hands to adjust and fix, which cannot meet the needs of rapid angle adjustment underground. Utility Model Content

[0005] In view of this, the present invention provides an explosion-proof LED mining lamp, including a connecting base, a conical cylinder fixedly installed on one side of the connecting base, a fixed cylinder fixedly installed at one end of the conical cylinder, a rolling ball installed inside the fixed cylinder, and a fixed tube connected inside the rolling ball; One end of the fixed tube is detachably connected to an explosion-proof lamp body, and an insert rod is slidably connected inside the fixed tube. A positioning plate is slidably connected to the outer surface of the insert rod. A spring is fixedly installed on the inner wall of the fixed tube, and a fixing rope is slidably connected to the inner wall of the fixed tube.
[0006] In this technical solution, the fixed tube can rotate with the rolling ball, and the rotation of the rolling ball and the fixed tube can be used to adjust the angle of the explosion-proof lamp body. The spring can push the insertion rod to move, and the insertion rod can enter the interior of the positioning plate. The connection between the insertion rod and the positioning plate can fix the fixed tube. By pulling the fixing rope, the insertion rod can be controlled to disengage from the positioning plate.
[0007] In the above technical solution, both the conical cylinder and the fixed tube are hollow inside, the fixed tube is made of high-strength alloy material, and the rolling ball can rotate inside the fixed cylinder.
[0008] In this technical solution, the rotation of the rolling ball can control the rotation of the fixed tube, thereby adjusting the angle of the explosion-proof lamp body.
[0009] In the above technical solution, the outer surface of the positioning plate is fixedly installed with the inner wall of the conical cylinder, and multiple sets of positioning holes are opened inside the positioning plate. The multiple sets of positioning holes are distributed in a divergent manner, and all the positioning holes have the same center. The outer surface of the insertion rod is slidably connected to the inside of the positioning plate.
[0010] In this technical solution, the fixing tube is fixed by the contact between the insertion rod and the positioning hole, and each set of fixed tubes after the angle is adjusted has a corresponding set of positioning holes.
[0011] In the above technical solution, a movable plate is fixedly installed at one end of the insertion rod, and the outer surface of the movable plate is slidably connected to the inner wall of the fixed tube.
[0012] In this technical solution, the movable plate can push the insertion rod to move, and the position of the insertion rod can be controlled.
[0013] In the above technical solution, the other end of the spring is fixedly installed on the outer surface of the movable plate, and the spring pushes the movable plate to move to the outside of the fixed tube.

[0016] In this technical solution, the movement of the insertion rod can be controlled by a fixed rope, which can make contact with the connection between the insertion rod and the positioning hole.
[0017] In the above technical solution, the explosion-proof lamp body is further provided with a protective cylinder detachably connected to the outside, and the outer surface of the fixing rope is slidably connected to the inside of the protective cylinder.
[0018] In this technical solution, the protective cylinder supports one end of the pull ring and the fixing rope, facilitating operation.
[0019] The beneficial effects of this utility model are: 1. This explosion-proof LED mining lamp, through the cooperation of the insert rod, positioning plate, and rolling ball, allows the fixed tube to rotate with the rolling ball. The rotation of the rolling ball and the fixed tube enables rapid adjustment of the angle of the explosion-proof lamp body. During adjustment, the movement of the fixed rope controls the movement of the insert rod. When the insert rod enters the interior of the positioning plate, the angle of the fixed tube is fixed; conversely, the angle of the fixed tube can be adjusted. Adjustment can be performed with one hand, making it more convenient and realizing the function of quickly adjusting the angle of the mining lamp, which is beneficial to meeting the needs of rapid adjustment in mine operations.
[0020] 2. This explosion-proof LED mining lamp, by setting springs and other components, can push the moving plate and the insertion rod to move. Multiple sets of positioning holes correspond to the angle after the insertion rod is rotated. Under the push of the spring, the inserted rod after rotation can enter the positioning holes with different tilt angles, thereby fixing the angle of the explosion-proof lamp body.

[0023] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.
[0024] In this application, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "middle," "vertical," and "horizontal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.
[0025] Example 1: This example provides an explosion-proof LED mining lamp, including a connecting base 1, a conical cylinder 2 fixedly installed on one side of the connecting base 1, a fixed cylinder 3 fixedly installed at one end of the conical cylinder 2, a rolling ball 4 installed inside the fixed cylinder 3, and a fixed tube 5 connected inside the rolling ball 4. One end of the fixed tube 5 is detachably connected to the explosion-proof lamp body 6. The inside of the fixed tube 5 is slidably connected to the insertion rod 7, and the outer surface of the insertion rod 7 is slidably connected to the positioning plate 8. A spring 9 is fixedly installed on the inner wall of the fixed tube 5, and a fixing rope 10 is slidably connected to the inner wall of the fixed tube 5.
[0026] Among them, the fixed tube 5 can rotate with the rolling ball 4, and the rotation of the rolling ball 4 and the fixed tube 5 can be used to adjust the angle of the explosion-proof lamp body 6. The spring 9 can push the insertion rod 7 to move, and the insertion rod 7 can enter the interior of the positioning plate 8. The connection between the insertion rod 7 and the positioning plate 8 can be used to fix the fixed tube 5. By pulling the fixing rope 10, the insertion rod 7 can be controlled to disengage from the positioning plate 8. The diameter of the rolling ball 4 is larger than the inner diameter of the fixed cylinder 3, so the rolling ball 4 will not lose contact with the inside of the fixed cylinder 3 and can still rotate. The spring 9 can generate a pushing force on the insertion rod 7 to move outward of the fixed tube 5. When the insertion rod 7 is not connected to the inside of the positioning plate 8, the angle can be adjusted by directly rotating the explosion-proof lamp body 6. At this time, the fixed rope 10 can be pulled with one hand to adjust. After adjusting the angle, the spring 9 pushes the insertion rod 7 into the inside of the positioning plate 8. The positioning plate 8 is used to fix one end of the fixed tube 5, realizing the quick fixation of the explosion-proof lamp body 6. The entire explosion-proof lamp body 6 is connected to the external power supply through the connecting line.
[0027] Example 2: This example provides an explosion-proof LED mining lamp. In addition to the technical solutions of the above examples, it also has the following technical features: the interiors of the conical cylinder 2 and the fixed tube 5 are hollow, the fixed tube 5 is made of high-strength alloy material, and the rolling ball 4 can rotate inside the fixed cylinder 3.
[0028] Among them, the rotation of the rolling ball 4 can control the rotation of the fixed tube 5, thereby adjusting the angle of the explosion-proof lamp body 6; The high-strength alloy structure of the fixing tube 5 provides stable support for the explosion-proof lamp body 6, while the rolling ball 4 provides relatively stable rotation and support for the alloy material.
[0029] Example 3: This example provides an explosion-proof LED mining lamp. In addition to the technical solutions of the above examples, it also has the following technical features: the outer surface of the positioning plate 8 is fixedly installed on the inner wall of the conical cylinder 2; multiple sets of positioning holes 11 are opened inside the positioning plate 8; the multiple sets of positioning holes 11 are distributed in a divergent manner; all positioning holes 11 have the same center; and the outer surface of the insertion rod 7 is slidably connected to the inside of the positioning plate 8.
[0030] The fixing of the fixed tube 5 is achieved by the contact between the insertion rod 7 and the positioning hole 11. Each set of fixed tubes 5 after the angle is adjusted has a corresponding set of positioning holes 11. When multiple sets of positioning holes 11 extend in a straight line, they intersect at a point. This intersection point is the same as the center of the rolling ball 4, ensuring that when the fixed tube 5 rotates to different angles, a set of positioning holes 11 is aligned with the center line of the fixed tube 5, which is suitable for various angle adjustments.
[0031] Example 4: This example provides an explosion-proof LED mining lamp. In addition to the technical solutions of the above examples, it also has the following technical features: a movable plate 12 is fixedly installed at one end of the insertion rod 7, and the outer surface of the movable plate 12 is slidably connected to the inner wall of the fixed tube 5.
[0032] Among them, the movable plate 12 can push the insertion rod 7 to move and can control the position of the insertion rod 7; The movable plate 12 can move linearly inside the fixed tube 5. When controlling the insertion rod 7, only the position of the movable plate 12 needs to be adjusted. At the same time, the movable plate 12 can also limit the insertion rod 7 from disengaging from the inside of the fixed tube 5.
[0033] Example 5: This example provides an explosion-proof LED mining lamp. In addition to the technical solutions of the above examples, it also has the following technical features: the other end of the spring 9 is fixedly installed on the outer surface of the moving plate 12, and the spring 9 pushes the moving plate 12 to move to the outside of the fixed tube 5.
[0034] Among them, the spring 9 can push the insertion rod 7 to move and control the insertion rod 7 to enter the interior of the positioning hole 11; Spring 9 can generate a pushing force on the insertion rod 7 to move outward of the fixed tube 5. Under the push of spring 9, the insertion rod 7 enters the interior of the positioning hole 11. The positioning plate 8 has a thickness. Since the center of the insertion rod 7 is aligned with the center of the contacting positioning plate 8, the positioning plate 8 will not easily detach from the positioning plate 8 when it enters the interior of the positioning hole 11.
[0035] Example 6: This example provides an explosion-proof LED mining lamp. In addition to the technical solutions of the above examples, it also has the following technical features: the other end of the fixing rope 10 is fixedly installed on the outer surface of the moving plate 12, and a pull ring 13 is fixedly installed on the other end of the fixing rope 10.
[0036] The fixed rope 10 can control the movement of the insertion rod 7 and make contact with the connection between the insertion rod 7 and the positioning hole 11; Pull ring 13 is set on the outside of fixed pipe 5. By pulling pull ring 13, one end of fixed rope 10 can be moved. When adjusting the angle of explosion-proof lamp body 6, pull ring 13 and control the rotation of explosion-proof lamp body 6. It can be operated with one hand, which is convenient and quick and meets the needs of rapid operation in mines.
[0037] Example 7: This example provides an explosion-proof LED mining lamp. In addition to the technical solutions of the above examples, it also has the following technical features: a protective cylinder 14 is detachably connected to the outside of the explosion-proof lamp body 6, and the outer surface of the fixing rope 10 is slidably connected to the inside of the protective cylinder 14.
[0038] The protective cylinder 14 supports one end of the pull ring 13 and the fixing rope 10, making it convenient to operate; The protective cylinder 14 can limit the position of the pull ring 13, making it convenient for the operator to directly grab and pull the pull ring 13.
[0039] Working principle: When adjusting the angle of the explosion-proof lamp body 6, pulling the pull ring 13 moves the lamp body 6. At this time, the pull ring 13 can control one end of the fixing rope 10 to move. The fixing rope 10 controls the insertion rod 7 to move into the interior of the fixing tube 5. At this time, the insertion rod 7 can disengage from the positioning hole 11, and then the angle of the explosion-proof lamp body 6 can be adjusted. By rotating the explosion-proof lamp body 6, the fixing tube 5 and the rolling ball 4 can be rotated. At this time, the angle of the other end of the fixing tube 5 changes. After the adjustment is completed, the spring 9 can push the insertion rod 7 into the positioning hole 11 at its position to fix the fixing tube 5.
