Detailed Description

The utility model is further described below with reference to examples, but not to be construed as being limited thereto, and any number of modifications which can be made by anyone within the scope of the claims are also within the scope of the claims.

Referring to fig. 1-2, the door handle painting fixing device of the utility model comprises a plug 1. A mounting cavity 2 is formed in the plug 1, a sliding plate 3 is slidably mounted in the mounting cavity 2, and a reset component is mounted on one side of the sliding plate 3 and used for resetting the elastic sheet 4. Four shell fragment 4 of evenly arranging are installed to the opposite side of sliding plate 3, and shell fragment 4 extends to the outside of installation cavity 2, and the thickness of shell fragment 4 is by the one end of sliding plate 3 toward the other end gradual change increase for steel ball 5 is at the in-process that moves backward, and shell fragment 4 can effectually be propped greatly, thereby makes its pore wall contact with the mounting hole, and the tensioning is in the mounting hole, realizes the centre gripping to the doorknob. A sliding cavity is defined by the four elastic sheets 4, steel balls 5 are arranged in the sliding cavity, the steel balls 5 are in contact connection with the side walls of the elastic sheets 4, and a limiting plate 6 is arranged on one side of each steel ball 5 to limit the inserting depth of the elastic sheets 4. And a driving assembly is arranged on one side of the limiting plate 6, and the driving end of the driving assembly is fixedly connected with the steel ball 5 and used for driving the steel ball 5 to move.

Specifically, the reset assembly comprises a first spring 7 and a telescopic rod 8. One end of the telescopic rod 8 is fixedly connected with the bottom of the mounting cavity 2, the other end of the telescopic rod 8 is fixedly connected with the sliding plate 3, and the first spring 7 is sleeved on the periphery of the telescopic rod 8. When the steel ball 5 moves towards the direction of the limit plate 6, the first spring 7 is stretched; when the steel ball 5 moves towards the direction of the plug connector 1, the elastic sheet 4 is reset under the action of the elastic force of the first spring 7.

Preferably, the telescopic rod 8 comprises an inner tube and an outer tube. One end of the inner pipe is fixedly connected with the bottom of the mounting cavity 2, one end of the outer pipe is fixedly connected with the sliding plate 3, the inner pipe is inserted into the outer pipe, and the inner pipe is inserted with a second spring extending into the outer pipe. In order to avoid the problem that the first spring 7 is easily stretched in continuous work to cause insufficient elasticity, the second spring is arranged in the telescopic rod 8 in the embodiment. Through the combined action of two springs, the risk that the spring is elongated can be effectively reduced, and the service life of the fixing device is prolonged.

Preferably, the end of the plug 1 is hemispherical to facilitate insertion into the mounting hole.

Preferably, shell fragment 4 is the arc form, and the height at shell fragment 4 middle part is greater than the height at its both ends to make steel ball 5 at the in-process that removes, can more effectually strut shell fragment 4, do benefit to the quick fixation to the door handle.

Preferably, the port department of installation cavity 2 is equipped with chamfer 9, and the junction of chamfer 9 and 1 outer wall of bayonet joint is equipped with the fillet to the removal of shell fragment 4 in installation cavity 2 reduces its damage to installation cavity 2 lateral wall. The round angle is arranged to avoid the sharp position at the end of the installation cavity 2 and reduce the risk of hurting people.

The drive assembly of this embodiment includes a protective housing 11, a lead screw motor 12, and a hand grip 13. Protection casing 11 installs in the one side that shell fragment 4 was kept away from to limiting plate 6, and lead screw motor 12 installs in protection casing 11, lead screw one end and the 5 fixed connection of steel ball of lead screw motor 12, and handheld handle 13 is installed in the one side that limiting plate 6 was kept away from to protection casing 11, has seted up adaptation chamber 14 in handheld handle 13, and adaptation chamber 14 is linked together with protection casing 11, and the lead screw other end of lead screw motor 12 is pegged graft in adaptation chamber 14. The end of the handle 13 is provided with a hanging lug 15.

The working principle of the utility model is as follows: in operation, the plug 1 and the spring plate 4 are plugged into the mounting hole of the door handle through the hand-held handle 13. Then, the screw motor 12 is started to drive the steel balls 5 to move towards the limiting plate 6. The sliding cavity enclosed by the elastic sheet 4 is narrower the closer to the side of the limit plate 6, so the elastic sheet 4 will be expanded during the moving process of the steel ball 5. And in the process that the elastic sheet 4 is expanded, the sliding plate 3 moves outwards, the spring is stretched, and the elastic sheet 4 is continuously moved out of the installation cavity 2 so as to adapt to the self deformation process. And after the elastic sheet 4 is tightly supported in the mounting hole, stopping the screw rod motor 12, and hanging the hanging lug at the end part of the handheld handle 13 on the steel wire.

When the door handle is disassembled, the steel ball 5 is driven to move towards the direction of the plug-in connector 1 only through the screw rod motor 12, and the spring and the elastic sheet 4 are reset to loosen the clamping of the door handle.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that those skilled in the art can make various changes and modifications without departing from the structure of the utility model, which will not affect the effect of the utility model and the practicability of the patent.
