Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0025] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that can be included in at least one implementation manner of the present utility model. The appearances of "in one embodiment" in different places in this specification do not all refer to the same embodiment, nor are they separate or alternative embodiments that exclude other embodiments.

[0026] Embodiment 1

[0027] Refer to Figures 1 to 3 , which is the first embodiment of the present utility model. This embodiment provides a fastening device. By setting the locking assembly 100 and the pressing assembly 200, the advantage of such a setting is to prevent the light bulb from falling off due to the influence of vibration on the lighting lamp, thereby preventing the reduction of the brightness of the tunnel.

[0028] Specifically, the locking assembly 100 includes a bolt 103, a first fixing member 101 provided on the bolt 103, and a second fixing member 102 provided on the bolt 103; and, the pressing assembly 200 includes a telescopic member 201, a pressing member 202 provided on the telescopic member 201, and a lighting hood 203 provided on the telescopic member 201; wherein, the first fixing member 101 and the second fixing member 102 can be clamped to the lighting hood 203 and limited by the thread of the bolt 103.

[0029] Wherein, the first fixing member 101, the second fixing member 102 and the pressing member 202 form a triangular stable structure to prevent the first fixing member 101 and the second fixing member 102 from loosening.

[0030] The first fixing member 101, the second fixing member 102 and the bolt 103 form a set to constitute the locking assembly 100, and each set of locking assemblies 100 can be installed together in a row.

[0031] One end of the telescopic member 201 close to the tunnel can be inserted into the fixing hole of the tunnel.

[0032] In summary, by setting the locking assembly 100 and the pressing assembly 200, after the worker clamps the first fixing member 101 and the second fixing member 102 on the lighting hood 203, the first fixing member 101 and the second fixing member 102 are limited by the thread of the bolt 103, and then by adjusting the length of the telescopic member 201, the ends of the lighting hood 203 are made to be on the same straight line. The advantage of this setting is to prevent the light bulb from falling off due to the influence of vibration on the lighting lamp, thereby preventing the brightness of the tunnel from decreasing.

[0033] Embodiment 2

[0034] Refer to Figures 1 to 3 , which is the second embodiment of the present utility model. Different from the previous embodiment, by setting the first fixing member 101, the second fixing member 102, the bolt 103, the telescopic member 201 and the pressing member 202, the advantage of this setting is to prevent the light bulb from falling off due to the influence of vibration on the lighting lamp, thereby preventing the brightness of the tunnel from decreasing.

[0035] Specifically, the first fixing member 101 includes a first limiting block 101b, one end of the first limiting block 101b is provided with a first convex block 101a, and a third screw hole adapted to the bolt 103 is provided on the first convex block 101a.

[0036] One end of the first limiting block 101b away from the first convex block 101a is provided with a first groove 101e adapted to the first convex block 101a, and a first screw hole 101c penetrating through the first limiting block 101b is provided on the inner wall of the top of the first groove 101e, and the first screw hole 101c is adapted to the bolt 103.

[0037] The bottom of the first limiting block 101b is provided with a first clamping hole 101d, and the second fixing member 102 includes a second limiting block 102b. The top of the second limiting block 102b is provided with a second clamping hole 102d.

[0038] One end of the second limiting block 102b is provided with a second convex block 102a, and a fourth screw hole adapted to the bolt 103 is provided on the second convex block 102a.

[0039] One end of the second limiting block 102b away from the second convex block 102a is provided with a second groove 102e adapted to the second convex block 102a. The inner wall of the bottom of the second groove 102e is provided with a second screw hole 102c penetrating through the second limiting block 102b, and the second screw hole 102c is adapted to the bolt 103.

[0040] Wherein, the first convex block 101a and the second convex block 102a of the first locking assembly 100 can be inserted into the first groove 101e and the second groove 102e of the second locking assembly 100.

[0041] The inner diameters of the first clamping hole 101d and the second clamping hole 102d are larger than the outer diameter of the lighting lamp cover 203, and can be adapted to lighting lamp covers 203 of various different sizes.

[0042] In summary, by providing the first fixing member 101, the second fixing member 102, the bolt 103, the telescopic member 201 and the extrusion member 202, the worker clamps the first clamping hole 101d on the first fixing member 101 and the second clamping hole 102d of the second fixing member 102 on the first lighting lamp cover 203, and then inserts the bolt 103 of the first locking assembly 100 into the third screw hole and the fourth screw hole by means of threaded rotation to fix the first fixing member 101 and the second fixing member 102. Then, after the worker clamps the first fixing member 101 and the second fixing member 102 of the second locking assembly 100 on the second lighting lamp cover 203, the first convex block 101a and the second convex block 102a of the second locking assembly 100 are inserted into the first groove 101e and the second groove 102e of the first locking assembly 100, and the bolt 103 of the second locking assembly 100 is inserted into the first screw hole 101c, the second screw hole 102c, the third screw hole and the fourth screw hole of the first locking assembly 100 by means of threaded rotation, so as to connect the first locking assembly 100 and the second locking assembly 100. And so on, to form a row.

[0043] Then the worker fixes one end of the fixed shell 201c to the lighting lampshade 203, and then adjusts the length of the plug rod 201a to adapt to the distance from the tunnel wall to the lighting lampshade 203, so that the side of the lighting lampshade 203 away from the tunnel wall is in the same straight line, and then inserts the end of the plug rod 201a away from the lighting lampshade 203 into the socket on the tunnel wall for fixed connection or fixed connection with the outer wall of the tunnel wall. The advantage of this arrangement is to prevent the lighting lamp from being affected by vibration and causing the bulb to fall off, thereby preventing the brightness of the tunnel from being reduced.

[0044] Example 3

[0045] Reference Figures 1 to 3 , which is the third embodiment of the utility model, is different from the previous embodiment in that, by providing a telescopic member 201 and an extruding member 202, the clamping and fastening of the lighting lampshade 203 by the first fixing member 101 and the second fixing member 102 through the bolt 103 is enhanced to prevent the lighting lampshade 203 from loosening.

[0046] Specifically, a circular protrusion is disposed on the top of the first limiting block 101 b and a circular protrusion is disposed on the bottom of the second limiting block 102 b , and the telescopic member 201 includes a fixed shell 201 c fixedly connected to the lighting lampshade 203 .

[0047] The insert rod 201a is slidably sleeved in the fixing shell 201c, and a through hole is opened on the fixing shell 201c, and a tightening rod 201b is threadedly sleeved in the through hole.

[0048] The extrusion member 202 includes a sleeve block 202b fixedly sleeved with the insertion rod 201a, and a pressing rod 202a abutting against the circular protrusion is arranged on the sleeve block 202b.

[0049] The distance between the two ends of the insertion rod 201 a is longer than the distance between the two ends of the fixing shell 201 c , and the pressing rod 202 a is inclined in a direction away from the locking assembly 100 .

[0050] Among them, the top of the first limit block 101b and the bottom of the second limit block 102b are both provided with circular protrusions, and the circular protrusions improve the tolerance of the pressing rod 202a.

[0051] A torsion spring is provided between the insertion rod 201a and the sleeve block 202b. When the sleeve block 202b is closer to the lighting lampshade 203, the angle at which the pressing rod 202a is opened by the circular protrusion becomes larger, and the pressing rod 202a is pressed more strongly on the circular protrusion under the deformation force of the torsion spring.

[0052] In summary, by providing the telescopic member 201 and the pressing member 202, when a worker aims to align the ends of the lighting lamp cover 203 in a straight line, the insertion rod 201a is slid within the fixed housing 201c and the tightening rod 201b is rotated threadedly to cause the bottom end of the tightening rod 201b to press against the outer wall of the insertion rod 201a for limiting. Since the distance from the wall surface to the lighting lamp cover 203 is shorter, the vibration frequency acting on the telescopic member 201 during tunnel vibration is faster. This means that the first fixing member 101 and the second fixing member 102 are more likely to become loose under the influence of vibration when clamping the lighting lamp cover 203 through the bolt 103. Therefore, when the insertion rod 201a slides and contracts in the direction closer to the lighting lamp cover 203, the pressing rod 202a that abuts and presses against the circular protrusion exerts a greater pressure on the circular protrusion under the action of the torsion spring, enhancing the clamping and fastening of the first fixing member 101 and the second fixing member 102 to the lighting lamp cover 203 through the bolt 103 and preventing the lighting lamp cover 203 from loosening.
