The utility model is achieved in that

A kind of lamp bracket is made of base plate, lamppost, connector, fixed head, and described lamppost is a pipe, is fixed on the base plate; Connector is oppositely " L " type, and pipe is fixed in one in its posterior end, and interior pipe box is gone in the lamppost, between dog screw is set; A transverse tube is installed on the described connector, and fixed head is installed in two ends of transverse tube.

One lateral aperture is arranged at the preceding bottom of described connector, and a connecting bolt bar passes this hole and cooperates with adjusting nut, and the other end of connecting bolt bar is fixed a transverse tube sleeve, between connecting bolt bar and connector dog screw is set; Transverse tube is enclosed within the transverse tube sleeve, and the transverse tube dog screw is set therebetween; The two ends of described transverse tube are equipped with the fluorescent tube fixed sleeving, are provided with the fluorescent tube adjustment screw between fluorescent tube fixed sleeving and the transverse tube; Fixed head is fixed on the fluorescent tube fixed sleeving; Switch base is installed on the connector.

One tight loop is set between described lamppost and the connector, between tight loop and the interior pipe tight loop dog screw is set; Between described lamppost and the base plate reinforcement is set; A substrate is set below the described base plate, base plate and substrate is connected and fixed with connecting bolt; One middle side part of base plate is fixed a base plate sleeve, and the endoporus of base plate sleeve is shaped on screw thread, and a substrate sleeve is fixed at the two ends of substrate same side respectively, and two bolts pass threads engaged in the hole of substrate sleeve and base plate sleeve respectively.

The utlity model has following advantage:

1, can adjust the height of lamp bracket, the position and the angle in space easily.

2, mounting or dismounting are convenient, improved operating efficiency, are adapted to various demands.

The specific embodiment

Shown in Fig. 1-2, the utility model mainly is made of base plate 2, lamppost 4, interior pipe 5, dog screw 6, connector 9, fixed head 10, transverse tube 11 etc.Base plate 2 fixes on the ground, and lamppost 4 is a pipe, is vertically fixed on the base plate 2, for gaining in strength, 3 reinforcements 18 is set between lamppost 4 and base plate 2.Connector 9 is oppositely " L " type, the one end is fixed in one and is managed 5, and interior pipe 5 is inserted in the lamppost 4, can move up and down therein, with height and the rotation therein of adjusting lamp bracket, to adjust the level angle of lamp bracket, screwed in place screw 6, the fixedly position of lamp bracket, a transverse tube 11 is installed on the connector 9, two ends of transverse tube 11 are separately installed with fixed head 10, and the lamp of explosion-proof lamp, fluorescent lamp and other kinds can be installed on the fixed head 10, so the scope of application of lamp bracket is wide.As in inflammable and explosive environment, using explosion-proof lamp, with switch base screw 17 switch base 16 is installed on the connector 9, the switch of explosion-proof lamp is placed on the switch base 16.During use, electric wire enters from the centre bore on the base plate 2, by lamppost 4, interior pipe 5, passes with the explosion-proof lamp switch from connector 9 and hole on interior pipe 5 relative positions and to join.

For using and adjust lamp bracket more easily, in the preceding bottom of connector 9 lateral aperture is set, as shown in Figure 2, a connecting bolt bar 21 passes this hole, cooperates with adjusting nut 20, and the other end of connecting screw rod 21 is fixed a transverse tube sleeve 14, as shown in Figure 4.Transverse tube 11 is enclosed within the transverse tube sleeve 14, when transverse tube 11 needs as shown in Figure 5, to adjust adjusting nut 20 with spanner when vertical direction is adjusted angle, drives transverse tube 11 and rotates, and adjusting finishes, and the dog screw of tightening between connecting bolt bar 21 and the connector 9 25 gets final product.Transverse tube 11 can move in transverse tube sleeve 14 and rotate, and it is fixing that transverse tube hold-down screw 15 is set therebetween.The two ends of transverse tube 11 are equipped with fluorescent tube fixed sleeving 12, and transverse tube 11 can move and rotate along fluorescent tube fixed sleeving 12,13, two explosion-proof lamp fixed heads 10 of fluorescent tube adjustment screw are set therebetween are separately fixed on the fluorescent tube fixed sleeving 12.

For dynamics and the reliability that increases adjustment, a tight loop 7 is set between lamppost 4 and connector 9, between tight loop 7 and the interior pipe 5 tight loop dog screw 8 is set.For the ease of mounting or dismounting and maintenance, a substrate 1 is set below base plate 2, one middle side part of base plate 2 is fixed a base plate sleeve 24, and the endoporus of base plate sleeve 24 is shaped on screw thread, and a substrate sleeve 23 is fixed at the two ends of the same side of substrate 1 respectively, two bolts 19 pass threads engaged in the hole of substrate sleeve 23 and base plate sleeve 24 respectively, then base plate 2 is a hinge with bolt 19, around substrate 1 rotation, during work, substrate 1 fixes on the ground, with connecting bolt 3 base plate 2 is fixed on the substrate 1.When mounting or dismounting or maintenance, connecting bolt 3 can be pulled down, base plate 2 can be around substrate 1 rotation, and then lamppost 4 tilts easy access and threading.As bolt 19 is pulled down, then lamp bracket integral body can be taken away, so mounting or dismounting, use, easy to adjust.Be provided with a through hole 22 is convenient to electric wire and passes in the bottom of lamppost 4.
