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.

The utility model provides an energy-saving explosion-proof torch as shown in figures 1-4, which comprises a barrel body 1, one end of the barrel body 1 is fixedly connected with a first long tube 4 which is used as an original grab handle of the explosion-proof torch, the inner cavity is a hollow structure for installing a storage battery and a lead, one side of the outer wall of the first long tube 4 is embedded with a USB charging interface 10 which is electrically connected with the storage battery in the inner cavity of the first long tube 4 so as to charge the storage battery for continuous use of the explosion-proof torch, the outer wall of the first long tube 4 is slidably sleeved with a second long tube 5, the outer wall of the first long tube 4 is sleeved with the second long tube 5, thereby the length of shortening the handle area of the explosion-proof torch is increased by utilizing the expansion between the second long tube 5 and the first long tube 4, one end of the first long tube 4 is fixedly connected with a reset spring 6, after the first long tube, thereby produce an elastic restoring force, be convenient for behind first long tube 4 and the 5 unblocks of second long tube, supplementary promotion second long tube 5 pops out, external thread groove 9 has been seted up to 4 tip outsides of first long tube, internal thread groove has been seted up to the tip of the inner wall of second long tube 5, second long tube 5 passes through internal thread groove and 9 threaded connection of the external thread groove of 4 tip of first long tube, the setting of internal thread groove 9 and external thread groove, can be convenient for lock through clockwise or anticlockwise rotation between first long tube 4 and the second long tube 5 and fix or the unblock is not hard up, reset spring 6's one end and the one end of the 5 inner walls of second long tube are equipped with slide mechanism.

Slide mechanism includes circular slab 7, one side of circular slab 7 and reset spring 6's one end fixed connection, circular slab 7 opposite side has seted up annular raceway 13, and annular raceway 13's inner chamber sliding clamping has a plurality of balls 8, when second long tube 5 rotates, drive a plurality of balls 8 through the inner wall of second long tube 5 and roll in annular raceway 13 on circular slab 7, thereby it is rolling friction to rotate the sliding friction between 5 inner walls of second long tube and reset spring 6, reduce the wearing and tearing of second long tube 5, the rotation of the second long tube 5 of being convenient for simultaneously.

The other end threaded connection of barrel 1 has protective cover 2, and the tip joint of the protective cover 2 inner chamber has transparent protection piece 3, plays the effect of a protection, prevents that the circuit board and the lamp holder of barrel 1 tip from exposing, improves the security that explosion-proof torch used.

One end fixedly connected with latch closure 11 of second long tube 5, one side cover of latch closure 11 is equipped with nylon fag end 12, and nylon fag end 12 covers in user's wrist department during the use, prevents that explosion-proof torch from dropping, is convenient for hang on the couple of wall when depositing, improves the convenience of use, and elastic silica gel cover 14 is equipped with to one pot head of second long tube 5, plays the effect of a buffering protection, prevents that second long tube 5 from producing the collision when popping out and causing the damage with the human body.

This practical theory of operation: when using explosion-proof torch, if need increase explosion-proof torch's grab handle district length, the user only needs manual anticlockwise rotation second long tube 5, make the internal thread groove of 5 inner walls of second long tube and the external screw thread groove 9 of 4 outer walls of first long tube separate gradually, internal thread groove separates the back with external screw thread groove 9 completely again, reset spring 6 is by the automatic stretching of compression state and resets, it stretches out the expansion from first long tube 4 to drive second long tube 5, thereby increase explosion-proof torch district length, when needing to shorten, the user only needs to promote second long tube 5, make the outside at first long tube 4 of second long tube 5 cover established, reset spring 6 compresses simultaneously, clockwise rotation second long tube 5 again, make the internal thread groove of 5 inner walls of second long tube and the external screw thread groove 9 threaded connection of 4 outsides of first long tube, realize fixing between first long tube 4 and the second long tube 5.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications and variations can be made in the embodiments or in part of the technical features of the embodiments without departing from the spirit and the scope of the invention.
