[0023] The specific implementation of the present invention is described in detail below. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0024] In the present invention, unless otherwise stated, the directional words such as "upper" and "lower" usually refer to the orientation in the assembled state. "Inside" and "outside" refer to the inside and outside relative to the outline of each component itself.

[0025] It should be noted that the terms "first", "second", etc. in the specification and claims of the utility model and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so as to describe the embodiments of the utility model described here. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0026] The utility model provides a lamp, which includes an upper cover body 11, a connecting tube 5 is sealed at a line inlet on the top of the upper cover body 11, the connecting tube 5 is provided with a first opening 12 communicated with the internal cavity of the upper cover body 11, the first opening 12 extends vertically and a clamping mechanism is installed inside the first opening 12, the clamping mechanism is provided with a cable channel for the cable to pass through, and the clamping mechanism is configured to be able to clamp the cable passed through the cable channel.

[0027] Specifically, after the cable is installed, the cable extends from the internal cavity of the upper cover 11 to the outside of the upper cover 11 through the cable channel of the clamping mechanism, and the clamping mechanism can clamp the cable passing through the cable channel. The deformation generated by the clamping mechanism can clamp the cable passing through the cable channel, and the outside of the deformed clamping mechanism can also be tightly attached to the inner wall of the connecting tube 5. Through the deformation of the clamping mechanism, the sealing between the cable and the clamping mechanism, and the sealing between the clamping mechanism and the connecting tube are achieved, that is, the sealing at the line inlet of the lamp is achieved, thereby preventing the explosion of the lamp caused by poor sealing at the line inlet of the lamp.

[0028] In some embodiments, the clamping mechanism includes a clamping cylinder, the diameter of which gradually decreases from top to bottom, and the cable channel vertically penetrates the clamping cylinder. The connecting cylinder 5 is configured to be conical barrel-shaped, and the outer side surface of the clamping cylinder is threadedly connected to the inner side surface of the connecting cylinder 5. Three slits are provided at the bottom of the clamping cylinder, and the three slits evenly divide the bottom of the clamping cylinder into three parts, and the three parts are spaced around the axis of the cable channel. After the cable is inserted into the cable channel, the clamping cylinder is rotated to rotate the clamping cylinder toward the upper cover body 11. During the process of the clamping cylinder rotating and moving toward the upper cover body 11, the connecting cylinder 5 will squeeze the lower part of the clamping cylinder, so that the width of the three slits gradually decreases, and then the lower diameter of the clamping cylinder gradually decreases, thereby clamping and sealing the cable. The connecting cylinder 5 will squeeze the lower part of the clamping cylinder, so that the clamping cylinder and the connecting cylinder 5 are sealed. Of course, the clamping mechanism can also be any other structural form that can achieve the above-mentioned technical effects, and the utility model is not limited.

[0029] In some embodiments of the utility model, the clamping mechanism includes an extrusion cylinder 1 and a clamping cylinder 2. The extrusion cylinder 1 is provided with a first passage 3 for the cable to pass through, and the extrusion cylinder 1 is threadedly connected to the top of the first opening 12 so that the extrusion cylinder 1 can be lifted and lowered along the axis of the first opening 12, and the extrusion cylinder 1 is provided with a first passage 3 for the cable to pass through. The clamping cylinder 2 is movably installed in the first opening 12, and the clamping cylinder 2 is located between the extrusion cylinder 1 and the upper cover 11, and the clamping cylinder 2 is provided with a second passage 4 for the cable to pass through, and the first passage 3 and the second passage 4 are connected to form a cable passage.

[0030] Among them, an internal thread is provided on the top hole wall of the first opening 12, and an external thread is provided on the outer peripheral wall of the extrusion cylinder 1, and the external thread and the internal thread are matched. Of course, the internal thread has a sufficient depth to ensure that the extrusion cylinder 1 has a sufficient range of movement, so that the extrusion cylinder 1 can produce sufficient deformation. For example, the depth of the internal thread can be 1 / 3-1 / 2 of the depth of the first opening 12. In this embodiment, the extrusion cylinder 1 is rotated to move the extrusion cylinder 1 toward the upper cover body 11, and the extrusion cylinder 1 will squeeze the clamping cylinder 2, and the clamping cylinder 2 will produce radial inward deformation, and the inner diameter of the clamping cylinder 2 will be reduced, thereby clamping and sealing the cable.

[0031] In some embodiments of the utility model, in order to facilitate the installation of the cable and reduce the damage of the cable caused by bending during use, the axis of the first opening 12, the axis of the first channel 3 and the axis of the second channel 4 coincide and pass through the center of the upper cover 11 together.

[0032] In some embodiments of the present invention, the chuck 2 is made of an elastic organic polymer material, such as a rubber material or plastic material with good thermal stability and corrosion resistance, etc. Preferably, a composite material of rubber and carbon black, or soft polyvinyl chloride is used.

[0033] like Figure 3 As shown, in some embodiments of the present invention, a partition 13 which can be pierced by the cable is provided at the bottom of the cartridge 2 , and the partition 13 seals the bottom of the second channel 4 of the cartridge 2 .

[0034] Specifically, when the partition 13 is not punctured, the partition 13 can form a seal for the second channel 4, preventing water vapor from entering the interior of the upper cover 11 and damaging the electrical components therein. When installing the cable, the cable punctures the partition 13, and a breach that only allows the cable to pass through is formed on the partition 13, and the edge of the breach contacts the cable and forms a seal, thereby preventing water vapor from entering the upper cover 11. Preferably, for a good sealing effect and ease of installation, the thickness of the partition 13 should be set to 0.5-1 times the thickness of the cable jacket of the cable.

[0035] In some other embodiments, a smooth surface is provided on the inner wall of the clamp 2. After the clamp 2 clamps the cable, the frosted surface can enhance the sealing between the clamp 2 and the cable, further improving the sealing of the lamp as a whole.

[0036] like Figure 2As shown, in some embodiments of the present invention, an annular extrusion ring 7 is provided at the bottom of the extrusion cylinder 1, the bottom surface of the extrusion ring 7 contacts the top surface of the chuck 2, the inner diameter of the extrusion ring 7 is larger than the diameter of the second channel 4, and the outer diameter of the extrusion ring 7 is larger than the outer diameter of the chuck 2. That is, when the extrusion cylinder 1 descends, the extrusion ring 7 is pressed on the outer ring portion of the top surface of the chuck 2, so as to cause the top of the chuck 2 to deform radially outward, and at the same time, cause the middle portion of the chuck 2 to deform radially inward.

[0037] like Figure 2 As shown, in some embodiments of the utility model, the top surface of the upper cover body 11 is provided with an annular support block 6, the bottom surface of the support block 6 contacts the bottom surface of the chuck 2, the inner diameter of the support block 6 is larger than the inner diameter of the chuck 2, and the outer diameter of the support block 6 is larger than the outer diameter of the chuck 2. That is to say, when the extrusion cylinder 1 descends, the support block 6 supports the outer ring part of the bottom surface of the chuck 2, so that the bottom of the chuck 2 is deformed radially outward, and the middle part of the chuck 2 is deformed radially inward.

[0038] In addition, the extrusion ring 7 and the support block 6 extrudes the clamp 2 in opposite directions, so that the top and bottom of the clamp 2 are deformed radially outward. While the top and bottom of the clamp 2 are deformed, the middle of the clamp 2 is deformed radially inward due to the pressure of the extrusion tube 1. When the middle of the clamp 2 contacts the cable, the clamp 2 can clamp and fix the cable. The radial outward deformation of the top and bottom of the clamp 2 causes the top and bottom of the clamp 2 to press against the inner wall of the connecting tube 5, thereby achieving a seal between the clamp 2 and the connecting tube 5; the middle of the clamp 2 clamps and fixes the cable, thereby achieving a seal between the clamp 2 and the cable, thereby achieving a seal at the cable inlet of the lamp.

[0039] like Figure 5 As shown, in some embodiments of the present invention, the outer periphery of the cartridge 2 is provided with an annular groove 9 distributed around the axis of the second channel 4, the annular groove 9 is located in the middle of the cartridge 2, and the annular groove 9 is recessed from the outer peripheral wall of the cartridge 2 to the inner peripheral wall of the cartridge 2. The annular groove 9 reduces the structural strength of the cartridge 2. Since the annular groove 9 is arranged in the middle of the cartridge 2, when the cartridge 2 is squeezed, the top and bottom of the cartridge 2 are deformed radially outward, and the middle of the cartridge 2 is deformed radially inward in accordance with the recessed direction of the annular groove 9. The middle of the cartridge 2 gradually shrinks and can eventually clamp and seal the cable.

[0040] like Figure 5As shown, in some embodiments of the utility model, the inner circumference of the chuck 2 is provided with an annular protrusion 8 distributed around the axis of the second channel 4, the annular protrusion 8 is located in the middle of the chuck 2, and the annular protrusion 8 protrudes from the inner circumferential wall of the chuck 2 toward the axis of the second channel 4. The annular protrusion 8 is arranged in the chuck 2, so that the inner diameter of the chuck 2 is reduced, and when the chuck 2 is squeezed to produce radial inward deformation, the annular protrusion 8 can clamp the cable as soon as possible. That is, when the chuck 2 is subjected to the pressure of the extrusion tube 1, it is easier to produce radial inward deformation in the middle of the chuck 2, and radial outward deformation at the top and bottom of the chuck 2. By providing the annular protrusion 8, on the one hand, the inner diameter of the middle of the chuck 2 is reduced, and on the other hand, the radial inward deformation of the middle of the chuck 2 is accelerated, and the chuck 2 can quickly clamp and seal the cable.

[0041] like Figure 4 As shown, in some embodiments of the present invention, an annular cavity 10 is provided in the middle of the cartridge 2 , and the annular cavity 10 is distributed around the axis of the second channel 4 .

[0042] Specifically, the provision of the annular cavity 10 separates the wall of the chuck 2 into two layers, which are a first sublayer facing the connecting tube 5 and a second sublayer facing the axis of the chuck 2. The provision of the annular cavity 10 reduces the structural strength of the middle portion of the chuck 2. Moreover, when the chuck 2 is squeezed by the squeezing tube 1, the first sublayer of the wall of the chuck 2 is deformed toward the connecting tube 5 so that the chuck 2 can be clamped in the connecting tube 5; the second sublayer of the wall of the chuck 2 is deformed toward the axis to clamp and seal the cable.

[0043] In other embodiments, a plurality of cavities are arranged in the middle of the clamp 2 and are distributed around the axis of the second channel 4. Similarly, when the clamp 2 is squeezed, the outer side of the clamp 2 can be clamped in the connecting tube 5, and the inner side of the clamp 2 can clamp and seal the cable.

[0044] In some embodiments of the present invention, the hardness of the top of the collet 2 and the hardness of the bottom of the collet 2 are greater than the hardness of the middle of the collet 2. Specifically, the hardness of the middle of the collet 2 is relatively small. When the collet 2 is squeezed, the middle of the collet 2 is more likely to deform radially, thereby guiding the middle of the collet 2 to clamp and seal the cable. In addition, since the hardness of the middle of the collet 2 is smaller, the collet 2 is in flexible contact with the middle of the cable, which helps to prevent damage to the cable jacket of the cable. Of course, those skilled in the art can flexibly set the hardness of the top of the collet 2, the hardness of the bottom of the collet 2, and the hardness of the middle of the collet 2 according to the on-site conditions, and the present invention does not limit this.

[0045] On the other hand, the utility model provides a lighting lamp, which includes an electrical component with a light-emitting component, a light-transmitting panel and the lamp housing in the above embodiment, wherein the light-transmitting panel is sealed and installed at the opening of the internal cavity of the upper cover body 11, and the electrical component is fixedly installed in the internal cavity of the upper cover body 11, and the light-emitting component of the electrical component faces the light-transmitting panel. The electrical component with the light-emitting component is installed in the upper cover body 11 of the lamp housing, and when in use, the light-emitting component of the electrical component can emit light, and the light is illuminated through the light-transmitting panel. The lighting lamp uses the above-mentioned lamp housing, and can also clamp and seal the cable at the inlet position through the clamping mechanism of the upper cover body, thereby preventing the explosion problem caused by the poor sealing at the inlet of the lighting lamp.

[0046] Preferably, the lighting lamp can be an explosion-proof lamp.
