As shown in fig. 8 and 9, the locking mechanism 32 includes an elastic round pad 321, a button 322 and a fixed block 326, the front end surface of the button 322 is fixedly connected with a connecting rod 323, one end of the connecting rod 323, which deviates from the button 322, penetrates through the elastic round pad 321 and is fixedly connected with the rear end surface of the fixed block 326, two groups of adjusting grooves are formed in the front end surface of the elastic round pad 321, two groups of extrusion pads 324 are arranged outside the elastic round pad 321, two groups of filling blocks 325 are fixedly connected with the rear end surface of the fixed block 326, and a second spring 327 is arranged on the front end surface of the fixed block 326.
Further, two sets of squeeze pads 324 are inserted into the two sets of penetrating holes 33, two sets of filling blocks 325 are respectively fitted with two sets of adjusting grooves, and the push button 322 is exposed from the upper end surface of the locking seat 31.
Specifically, by pressing the button 322 to make the fixed block 326 move down, the filling block 325 is withdrawn from the inside of the adjusting slot, the cable 2 is extruded to squeeze the pad 324 when passing through the inside of the penetrating hole 33, the pad 324 is extruded to squeeze the elastic round pad 321 to make the adjusting slot shrink, thereby the cable 2 is convenient to pass through the inside of the penetrating hole 33, the button 322 is released, the second spring 327 is recovered to deform to push the fixed block 326 to move up, the filling block 325 is made to enter the inside of the adjusting slot, the pad 324 enters the inside of the penetrating hole 33 to lock the cable 2 by squeezing, and the convex ring outside the cable 2 can further improve the locking effect.
It should be noted that the pressing pad 324 can rotate, that is, the pressing pad 324 rotates under the action of friction force when the cable 2 is pulled out, and the top of the filling block 325 is hemispherical.
Working principle: when the cable 2 is pulled out to a proper length, the button 322 is loosened, the cable 2 is locked, heat generated during the working of the power supply body can be stored by the heat storage layer 22, then the heat is dissipated through the cable 2 outside the power supply shell 1, after the working of the emergency power supply is finished, the button 322 is pressed down again, the cable 2 can be wound outside the winding roller 1231 under the action of the spring 1232, and dirt on the surface of the cable 2 is filtered by the sealing ring 1123 in the winding process of the cable 2, so that the cable 2 is kept in a clean state after being wound.
The invention provides an LED lamp emergency power supply assembly which comprises: through battery case 11 and assembly shell 12 cooperation installation, make the power supply body have a relatively sealed environment in power supply case 1 inside, copper and aluminum alloy compound's heat storage layer 22 has the heat accumulation effect, can absorb the heat that the power supply body during operation produced, and then make the power supply body can keep in a relatively suitable ambient temperature for a long time, cable 2 rolling is outside wind-up roll 1231 simultaneously, after wind-up roll 1231 outside wind-up roll cable 2, its holistic external diameter can become big, wind-up roll 1231 after the external diameter grow can extrude the inner chamber wall of assembly shell 12 for spring one takes place pulling force deformation, wind-up roll 1231 removes to power supply body one side, reach better effect that maintains power supply body ambient temperature.
Secondly, through setting up cable 2, cable 2 is pulled out the back, and cable 2 of accessible pull-out part dispels the heat, guarantees power supply body's operation effect, and 2 is pulled the back, and the whole external diameter of wind-up roll 1231 diminishes, and under spring one's effect, wind-up roll 1231 removes to deviating from power supply body one side for open environment area increases around the power supply body, improves heat dispersion.
Moreover, through setting up seal assembly 112, wherein seal assembly 112 outside has seted up guide way 1122, and guide way 1122 inside fixedly connected with a plurality of sets of sealing washer 1123 that set up at intervals for cable 2 passes guide way 1122, and the protruding circle can extrude sealing washer 1123 for gas can't get into battery case 11 inner chamber because of cable 2's tensile, and when cable 2 retrieves by cable receive the subassembly 123 and wind, sealing washer 1123 also can filter the filth on cable 2 surface, keeps cable 2 to be in clean state after being rolled up.
And, through setting up cable locking subassembly 3, wherein cable locking subassembly 3 inside is provided with locking mechanism 32, press button 322, fixed block 326 moves down, filling block 325 is from the inside withdrawal of adjustment tank, can extrude extrusion pad 324 when cable 2 passes through from permeating hole 33 inside, extrusion pad 324 extrudees elasticity circular pad 321 for the adjustment tank reduces, thereby cable 2 is convenient for pass through from permeating hole 33 inside, loosen button 322, spring two 327 can resume deformation and can promote fixed block 326 and move up, make filling block 325 get into the adjustment tank inside, extrusion pad 324 gets into and passes through hole 33 inside and locks cable 2 through the extrusion, the outside bulge loop of cable 2 can further improve the locking effect.
