Detailed description of the invention
In order to make those skilled in the art person understand technical scheme of the present invention better, be described in further detail below in conjunction with drawings and Examples.
The present invention installs and removes the push-pull device at fixed of light fixture from the slope of thread principle of drawing horse, in conjunction with the factor such as practical set environment of special lamp, is integrated into have employed each Function in Order in a device.Maintenance personal only needs turning handle, just can extract wick out 20CM by the power of 5 kilograms, completes and opens the most difficult step of light fixture.
The present invention installs and removes the structure of the push-pull device at fixed embodiment of light fixture as shown in Figure 1, and figure comprises catching 6, bearing cylinder 5, screw rod 4, rotary handle 3 and suspension assembly 7.Fig. 2 is the stereogram of embodiment, and Fig. 3 is the explosive view of embodiment.
In figure, the upper end of catching 6 is hinged on the hypomere of the outer wall of bearing cylinder 5 by bearing pin 8, the endoporus of bearing cylinder 5 is provided with rectangle internal thread, and screw rod 4 is provided with the rectangle external screw thread matched with the internal thread of bearing cylinder 5, and the rotary handle 3 with the axes normal of screw rod 4 is crossed on the top of screw rod 4.Suspension assembly 7 is suspended on the lower end of screw rod 4 and can rotates around the axis of screw rod 4.The hanging tool that suspension assembly 7 can be changed comprises the hook 72 for tractive, and for the addendum cone 75 that pushes and push rod 76.
As shown in Figure 4, suspension assembly 7 comprises hangoff receptacle 71 in the structural representation of the suspension assembly 7 with hook 72 of the push-pull device at fixed embodiment of mounting or dismounting light fixture, pulling force or thrust that the lower end of screw rod 4 is connected with the top of hangoff receptacle 71 for accepting hangoff receptacle 71.The pulling force that the bottom of hangoff receptacle 71 can be connected for accepting hook 71 with the top of hook 72, the thrust that the bottom of hangoff receptacle 71 can also be connected for accepting addendum cone or push rod with the top of addendum cone 75 or push rod 76.Fig. 5 is the explosive view of the suspension assembly 7 with hook 72.
In figure, the lower end of screw rod 4 is the step cutting pattern 41 of inverted T shape rotary body; The top of hangoff receptacle 71 is provided with the round stepped hole 711 of the inverted T shape matched with the step cutting pattern 41 of screw rod 4 lower end.Wherein hangoff receptacle 71 can rotate relative to pulling force screw rod 4 within the scope of 360 degree.
The bottom of hangoff receptacle 71 is provided with the T-slot 712 can installing hanging tool, comprises the narrow groove 7122 of rectangle below rectangle sipes 7121 and rectangle sipes 7121.The top of hook 72 is provided with the T-shaped rectangular step 721 matched with the T-slot 712 of hangoff receptacle 71 bottom.The both sides of the narrow groove 7122 of the T-slot 712 of hangoff receptacle 71 bottom are respectively arranged with the locating hole 713 for installing elastic positioning member 74, and two sides linking up with the narrow portion of the rectangular step 721 on 72 tops are provided with the positioning pit 722 corresponding with elastic positioning member 74.
Hangoff receptacle 71 comprises and to be locked two the somatotype bodies be integrated by bolt 73, its die joint through circle stepped hole 711 axis and overlap with the cross section at T-slot 712 center.Circle stepped hole 711 is blind hole, and the die joint of the seat 71 that is draped is divided into the semicircular step groove of two lower end closed.Locating hole 713 is also blind hole, the semicircular elongated slot that the die joint of the seat 71 that is also draped is divided into two outer ends to close.Four angles of a somatotype body of hook base 71 are provided with screwed hole 714, and correspondence four angles of another somatotype body are provided with bolt hole and and the counterbore 715 of through hole outer end receive bolts head.The step cutting pattern 41 of screw rod 4 lower end, when locking two somatotype bodies of hangoff receptacle 71, is placed in two semicircular step grooves.Elasticity location group 74 comprises steel ball 741, spring 742; Steel ball 741, spring 742, when locking two somatotype bodies of hangoff receptacle 71, are placed in two semicircular elongated slots.
As shown in the figure, the two ends of the T-slot 712 of hangoff receptacle 71 bottom are not closed, and the T-shaped rectangular step 721 on the top of hook 72 can insert in the T-slot 712 of hangoff receptacle 71 bottom.After being in place, the positioning pit 722 that steel ball 74 falls into hook 72 top automatically clamps.After T-shaped rectangular step 721 inserts T-slot 712, oppress steel ball 741 two-point locating by spring 742, obtain relatively fixing.When retrieving and change hook 72, need release hook 71 from the side, steel ball 741 will unclamp.
The bottom of catching 6 is provided with the coupler body 61 for catching on lamp casing; The lower surface of catching 6 is provided with projection for being supported on lamp casing end face or indenture.Catching 6 is three, is distributed on three directions of bearing cylinder 5 outer wall.Make straight line quiet pulling force during work, convenient and labor-saving, stable performance.
Install and remove the embodiment of the push-pull device at fixed of light fixture for dismantling explosion-proof lamp, as shown in Figure 6.With the mode that screw rod 4 spiral of trapezoidal thread pulls out, the structure of pulling back that coordination hinge supports in three catchings 6 at the adjustable folding angle of bearing cylinder 5 outer wall bottom.During use, adopt the lower surface of catching 6 to withstand the bead of lamp casing, the handle ring or the cover that the hook 72 of suspension assembly 7 are caught on light fixture inner core are fixedly fastened, and screw handle 3, then light fixture inner core can be pulled out.By regulating the Support Position of catching 6 on the housing of light fixture, the needs of different lamps dismounting can be met.
If the hook 72 being used for tractive is replaced by addendum cone for pushing or push rod by the push-pull device at fixed of mounting or dismounting light fixture, also can inner core be reinstalled in the housing of light fixture reverse operating, similar common function of drawing horse.
The push-pull device at fixed that the present invention installs and removes light fixture efficiently solves the problem of uncapping of the maintenance of special lamp, the especially sealing cover of IIC class light fixture, and extracts the inner core comparatively difficult problem of light fixture out.Light fixture significantly can reduce the maintenance time of light fixture by coordinating this device, increases light fixture maintainability, thus avoids the economic loss that client cannot dismantle because of light fixture, will bring greatest benefit to user.
The present invention will improve explosion-proof lamp opening speed, especially coordinate IIC place explosion-proof lamp to safeguard and will use, adopt specialized designs, and performance and function have and improve greatly.
The advantage that the present invention installs and removes the push-pull device at fixed of light fixture has: 1, size is little portable, but the scope of application is large, is suitable for all cylindrical parts light fixtures of diameter 50mm ~ 4mm scope; 2, there is various catching 6 to match, be matched with various flange bead; 3, adopt the helical rotation of screw rod 4, the pulling force of generation is large, and good reliability is make the quiet pulling force of straight line, convenient and labor-saving, stable performance during work.
Foregoing, is only preferred embodiment of the present invention, not carries out scope restriction to the present invention.Those skilled in the art, according to central scope of the present invention and spirit, can carry out corresponding flexible or amendment very easily.Therefore protection scope of the present invention should be as the criterion with the covering scope of claim.
