Description

Technical Field

[0001] The present invention relates to the technical field of mining lamps, and in particular to a mining lamp protective cover. Background Art

[0002] During the mining process, lighting is required in the mine, mainly using mining lamps. When using the mining lamps, protective covers are required to protect them.

[0003] The existing mining lamp protective cover mainly protects the lamp body of the mining lamp through a wire cover to prevent mining tools and equipment from contacting the lamp beads; the existing mining lamp protective cover is connected to the lamp body by bolts, which makes maintenance and disassembly relatively complicated. At the same time, when the wire cover collides with the side of an external object, the bolt connection cannot unload the force, and the wire cover is easily damaged.

[0004] Therefore, the present application provides a mining lamp protective cover, which can improve the safety of the mining lamp. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a mining lamp protective cover to solve the problem that the mining lamp protective cover in the prior art described in the background art is difficult to disassemble and repair and is easily damaged.

[0006] In order to solve the above problems, the present invention provides the following technical solutions: a mining lamp protective cover, comprising

[0007] Positioning sleeve, outer periphery of lamp holder;

[0008] A mounting ring, a fixed sleeve arranged on the outer wall of the positioning sleeve;

[0009] The rotating cover is rotatably connected to the outer circumferential wall of the positioning sleeve through a bearing;

[0010] A positioning ring, a fixed sleeve is arranged on the outer circumferential wall of the rotating cover at one end away from the positioning sleeve;

[0011] A plurality of arc-shaped steel wire rods, one end of which is detachably connected to the positioning ring and the other end is fixedly connected to the connecting plate;

[0012] The positioning ring has positioning grooves at positions corresponding to the steel wire rods, and the inner sidewalls of the positioning grooves have clamping grooves. The sidewall of the steel wire rod extending into the positioning grooves has a clamping protrusion that is clamped into the clamping grooves.

[0013] The transparent cover is detachably connected to the inner wall of one end of the rotating cover away from the positioning sleeve.

[0014] Preferably, a plurality of first heat sinks arranged in an annular shape are fixedly connected to the outer circumferential wall of the rotating cover.

[0015] Preferably, a plurality of second heat sinks are fixedly connected to the outer circumferential wall of the positioning sleeve.

[0016] Preferably, the open end of the transparent cover is fixedly connected with an external threaded sleeve, and the inner wall of the rotating cover is further provided with a threaded groove at a position corresponding to the external threaded sleeve, and the external threaded sleeve is connected to the threaded groove through threads.

[0017] The advantages of adopting the above technical solution are:

[0018] In this application, the locking protrusion on the steel wire rod engages with the locking groove in the positioning groove, so that the steel wire rod can be easily removed from the positioning ring on the rotating cover. At the same time, when external force contacts the side of the steel wire rod, the steel wire rod can drive the rotating cover to rotate on the positioning sleeve through the positioning ring, and the lateral impact force is released through rotation, which can reduce damage to the rotating cover.

DETAILED DESCRIPTION

[0026] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0027] like Figure 1-5 In the first embodiment, a mining lamp protective cover includes

[0028] Positioning sleeve, outer periphery of lamp holder;

[0029] The mounting ring 30 is fixedly mounted on the outer wall of the positioning sleeve 20. The mounting ring 30 and the positioning sleeve 20 are integrated to increase the connection strength.

[0030] The rotating cover 10 is rotatably connected to the outer circumferential wall of the positioning sleeve 20 through a bearing;

[0031] A positioning ring 60 is fixedly mounted on the outer circumferential wall of the rotating cover 10 at one end away from the positioning sleeve 20. The positioning ring is integrated with the rotating cover to increase the connection strength.

[0032] Several steel rods 50 are arc-shaped, one end of which is detachably connected to the positioning ring 60 and the other end is fixedly connected to the connecting plate 51. The connecting plate 51 is made of iron and is welded to the steel rods 50;

[0033] The positioning ring 60 has positioning grooves 61 at positions corresponding to the steel rod 50. The inner sidewall of the positioning groove 61 has a clamping groove 62. The sidewall of the steel rod 50 extending into the positioning groove 61 has a clamping protrusion 52 that is clamped into the clamping groove 62. The clamping protrusion 52 is integral with the steel rod 50. The outer wall of the steel rod 50 is also fixedly sleeved with a retaining ring 53.

[0034] The transparent cover 40 is detachably connected to the inner wall of the rotating cover 10 at one end away from the positioning sleeve 20 .

[0035] This embodiment is implemented as follows:

[0036] When the present application is in use, when an external force laterally impacts the side wall of the cover body formed by the steel wire rod 50, the steel wire rod 50 will be subjected to the impact force, a part of which is converted into a rotational force. The steel wire rod 50 drives the rotating cover 10 to rotate through the positioning ring 60, so that the rotating cover 10 rotates on the positioning sleeve 20. The rotation of the rotating cover 10 causes the cover body formed by the steel wire rod 50 to rotate, and the lateral external force will be gradually removed by the rotating steel wire rod 50, thereby playing a role in protecting the steel wire rod 50.

[0037] At the same time, the locking protrusion 52 on the steel wire rod 50 in the present application can enter the positioning groove 61 and be locked in the locking groove 62, which is very convenient when it needs to be removed or installed, avoiding the traditional bolt connection method.

[0038] As an optimization solution for this embodiment, a plurality of annularly arranged first heat sinks 11 are fixedly connected to the outer circumferential wall of the rotating cover 10. The first heat sinks 11 and the rotating cover 10 are both made of aluminum alloy and are integrally formed. The first heat sinks 11 enhance heat dissipation, as aluminum alloy has excellent heat dissipation properties.

[0039] The outer circumferential wall of the positioning sleeve 20 is fixedly connected to a plurality of second heat sinks 21. The first heat sink 21 and the rotating cover 20 are both made of aluminum alloy and are integrated. The second heat sink can improve the heat dissipation effect, and the aluminum alloy has a good heat dissipation effect.

[0040] As an optimization solution of this embodiment, the open end of the transparent cover 40 is fixedly connected to an externally threaded sleeve 41. The externally threaded sleeve 41 and the transparent cover 40 are integral. The inner wall of the rotating cover 10 is also provided with a thread groove 42 at a position corresponding to the externally threaded sleeve 41. The externally threaded sleeve 41 and the thread groove 42 are connected by threads. This connection between the externally threaded cover 41 and the thread groove 42 makes the transparent cover 40 easy to remove and replace.

[0041] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the present invention, which all fall within the scope of protection of the present invention.
