Abstract
The utility model provides a locking and fixing device fixed on the periphery of an embedded light fixture with a fixing frame. The locking and fixing device includes a screw penetrating into from the lower end of the fixing frame and out from the upper end of the fixing frame. The locking and fixing device also comprises a spring sheet situated in the fixing frame and movably sleeved on the screw, and a locknut situated above the fixing frame and sleeved on the screw. The locking and fixing device further comprises a limiting baffle plate and a guiding rib situated on the external side of the screw, wherein the limiting baffle plate and the guiding rib are adjacent and perpendicular to each other. The limiting baffle plate has an inclined side, and the guiding rib has an inclined surface. The locking and fixing device is firm and reliable, and is convenient for installation.
Description
Technical field
The utility model relates to a kind of locking and fixing device.
Background technology
Traditional locking and fixing device that is used for recessed light fixture utilizes screw thread to regulate the stroke of stator.This structure is for the article of concealed installation, and stator is run out easily, causes installing inconvenient.When particularly dismantling, the stator of horizontal direction might also be in mounted state, may cause cannot take out article.
Therefore, be necessary to design a kind of new locking and fixing device, to improve above-mentioned defective.
The utility model content
The purpose of this utility model provides a kind of solid and reliable, easy for installation locking and fixing device.
The purpose of this utility model is achieved through the following technical solutions: a kind of locking and fixing device, be fixed in the outer rim of a recessed light fixture, described recessed light fixture has a fixed frame, described locking and fixing device comprises a screw rod, described screw rod penetrates from the lower end of described fixed frame and passes from the upper end of described fixed frame, an and shell fragment, described shell fragment is positioned at described fixed frame and movable being sheathed on the described screw rod, an and stop nut, described stop nut is positioned at described fixed frame top and is sheathed on described screw rod, described locking and fixing device comprises that further a postive stop baffle and a guiding rib are positioned at the outside of described screw rod, vertical and the adjacent setting of described postive stop baffle and described guiding rib, described postive stop baffle has an inclined lateral side, and described guiding rib has an inclined plane.
Further, when described shell fragment was positioned at described fixed frame, described guiding rib was between described shell fragment and described screw rod.
Further, when described shell fragment was positioned at described fixed outer frame, described shell fragment was between the sidewall of described guiding rib and described fixed frame.
The utility model locking and fixing device has following advantage:
(1) because described postive stop baffle and described guiding rib are set, thereby when mounting and dismounting described recessed light fixture, described postive stop baffle and described guiding rib can impel described shell fragment to be in place smoothly and dismounting smoothly, and described postive stop baffle can prevent that described shell fragment from arbitrarily changeing toward described fixed outer frame, thereby easy for installation.
Description of drawings
Fig. 1: the schematic diagram when not installing for the utility model locking and fixing device;
Fig. 2: be the schematic diagram of the utility model locking and fixing device installation process;
Fig. 3: the schematic diagram that installs for the utility model locking and fixing device.
The implication of each Reference numeral sees the following form among the figure:
The specific embodiment
Below in conjunction with accompanying drawing technical solutions of the utility model are described further:
As Figure 1-3, the utility model locking and fixing device is used for installing and fixing of article (recessed light fixture etc.), utilizes screw thread to regulate the stroke of shell fragment, increases a postive stop baffle and guiding rib thereof.
Described locking and fixing device is fixed in the outer rim of a recessed light fixture 1, described recessed light fixture has a fixed frame 11, described locking and fixing device comprises a screw rod 2, described screw rod 2 penetrates from the lower end of described fixed frame 11 and passes from the upper end of described fixed frame 11, an and shell fragment 3, described shell fragment 3 is positioned at described fixed frame 11 and movable being sheathed on the described screw rod 2, an and stop nut 4, described stop nut 4 is positioned at described fixed frame 11 tops and is sheathed on described screw rod 2, described locking and fixing device comprises that further a postive stop baffle 5 and a guiding rib 6 are positioned at the outside of described screw rod 2, described postive stop baffle 5 and the 6 vertical and adjacent settings of described guiding rib, described postive stop baffle 5 has an inclined lateral side 51, and described guiding rib 6 has an inclined plane 61.
When described recessed light fixture 1 is not also installed, counterclockwise twisting described screw rod 2 impels described shell fragment 3 up to move, described shell fragment will will received in described fixed frame 11 under the effect of described postive stop baffle 5, twist motionless up to described screw rod 2, be in state shown in Figure 1, the described shell fragment 3 of this moment will can not run outward.
When described recessed light fixture 1 is installed, clockwise direction is twisted described screw rod 2 and is impelled described shell fragment 3 to move down, described shell fragment 3 is changeing outside described fixed frame 11 under the effect of described inclined plane 61 and self friction power, move down (see figure 2) to contacting and carry over described inclined lateral side 51 with described postive stop baffle 5, until the following end in contact firm (see figure 3) of described shell fragment 3 with described fixed frame 11, described shell fragment 3 is positioned at described fixed frame 11 when outer, and described shell fragment 3 is between the sidewall of described guiding rib 6 and described fixed frame 11.
When dismantling described recessed light fixture 1, counterclockwise twisting described screw rod 2 impels described shell fragment 3 to move up, described shell fragment 3 is being received in described fixed frame 11 under the effect of described postive stop baffle 5, tighten fully until described screw rod 2, this moment, described shell fragment 3 was completely retracted in the described fixed frame 11, got back to the state of Fig. 1.When described shell fragment 3 was positioned at described fixed frame 11, described guiding rib 6 was between described shell fragment 3 and described screw rod 2.Because the setting of described postive stop baffle 5 and described guiding rib 6 makes when the described recessed light fixture of installation and removal, and is solid and reliable, easy for installation.
To sum up, the utility model locking and fixing device has following advantage:
(1) because described postive stop baffle and described guiding rib are set, thereby when mounting and dismounting described recessed light fixture, described postive stop baffle and described guiding rib can impel described shell fragment to be in place smoothly and dismounting smoothly, and described postive stop baffle can prevent that described shell fragment from arbitrarily changeing toward described fixed outer frame, thereby easy for installation.
It is emphasized that: above only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did.
