Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides an embodiment:

a lighting lamp holder for road construction comprises a lamp holder disc 1, a plurality of lamp holder legs 2 are hinged to the bottom end of the lamp holder disc 1 in a circumferential array mode, the lamp holder legs 2 are hinged to the lamp holder disc 1 through first hinges 13, the bottom ends of the lamp holder legs 2 are hinged to a lamp holder base 3 through another hinge, the lighting lamp holder base 3 is used for adjusting the angle of the lamp holder base 3 to guarantee the stability of device support, connecting rods 4 are mounted at the middle and lower ends of the inner sides of the lamp holder legs 2, connecting blocks 5 are arranged above the connecting rods 4, the connecting blocks 5 and the connecting rods 4 and the lamp holder legs 2 are hinged and connected through second hinges 12, first threaded holes 14 are formed in the connecting blocks 5, positioning rods 6 are connected with the first threaded holes 14 in a threaded mode, external threads matched with the first threaded holes 14 are formed in the positioning rods 6, the top ends of the positioning rods 6 penetrate through the lamp holder disc 1, and trays 8 are fixed at the, the lamp holder disc 1 is provided with a through hole 15 matched with the positioning rod 6, and the positioning rod 6 is rotatably arranged in the through hole 15 through a bearing.

The inside of locating lever 6 is formed with first recess 11 (first recess 11 is laid along the axial direction of locating lever 6, vertical setting promptly), and the inside of first recess 11 is inserted and is equipped with dead lever 7, it is fixed through bolt 9 between dead lever 7 and the locating lever 6, locating lever 6 and dead lever 7 with one side respectively seted up with bolt 9 mutually supporting second screw hole 16 and second recess 10 (all be formed with on the cell wall of second screw hole 16 and second recess 10 and match in the internal thread of bolt 9), the size of dead lever 7 matches each other with the size of first recess 11, guarantee better axiality between dead lever 7 and the locating lever 6. When the lamp holder legs 2 are in the original position (namely when not unfolded), the length of the fixed rod 7 is larger than the length of the bottom end of the positioning rod 6 to the ground; in practical use, the bolt 9 is in threaded connection with the second threaded hole 16 and the second groove 10 and then is pressed against the bottom of the second groove 10, so that the fixed rod 7 is prevented from moving in the radial direction in the using process; the bottom of dead lever 7 sets up to the point form, the distance size between the top of dead lever 7 point form part is greater than the size that normal people's hand held the fist height and is used for when turning out bolt 9 apart from the size between 6 bottoms of locating lever, through holding the distance between dead lever 7 and the 6 bottoms of locating lever, make the steady roll-off of dead lever 7 from first recess 11 prick ground, ensure that the device is placed and is fixed to it when the comparatively soft position of soil property, can see according to description figure 4, the spout has been seted up on the left side inner wall of locating lever 6, the left side of dead lever 7 is fixed with the slider (do not mark in the picture) of mutually supporting with the spout, its effect is for guaranteeing that dead lever 7 steadily slides in locating lever 6, and can not change the slip direction, make things convenient for later stage bolt 9's fixed.

The working principle is as follows: when placing the lighting lamp holder, rotate lighting lamp holder tray 8 earlier for the locating lever 6 with 8 bottom fixed connection of lighting lamp holder tray rotates together, and the cover is established at connecting block 5 of 6 surfaces of locating lever and is driven the downstream at the screw thread, and connecting rod 4 expandes under the effect of second hinge 12, adjusts suitable angle, and lighting lamp holder leg 2 and lighting lamp holder base 3 can prop up whole lighting lamp holder structure under the effect of first hinge 13.

When the soil is soft, the bolt 9 is firstly rotated out, so that the bolt 9 is separated from the second groove 10, at the moment, the fixing rod 7 does not have a locking device in the positioning rod 6, the fixing rod 7 moves downwards from the first groove 11 under the action of gravity until one end of the fixing rod 7, which is far away from the positioning rod 6, is inserted into the ground, and then the bolt 9 is reversely rotated to realize the relocking of the fixing rod 7 and the positioning rod 6; then the lamp bracket tray 8 is rotated to realize the synchronous expansion of the lamp bracket legs 2, the placement of the lighting lamp bracket is completed, and finally the lighting lamp is placed on the lamp bracket tray 8.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
