fig. 3 is a schematic structural diagram of a fixing member according to an embodiment of the present invention;
wherein: the rear panel 1, the fixing piece 2, the sealing piece 3, the screw hole 11, the bump 21, the fixing ring 22, the notch 23, the shielding part 31, the connecting part 32 and the retaining ring 33.
Detailed Description
The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.
The screw hole 11 sealing structure of a door lock panel of this embodiment, as shown in fig. 1, includes rear panel 1, mounting 2 and sealing 3, be equipped with screw hole 11 on the rear panel 1, mounting 2 is the cyclic annular structure, mounting 2 inserts in the screw hole 11, the outer wall extrusion of mounting 2 is in the inboard of screw hole 11, sealing 3 includes shielding portion 31 and connecting portion 32, shielding portion 31 set up in the one end of connecting portion 32, the other end of connecting portion 32 inserts the inboard of mounting 2.
The outer wall of the fixing piece 2 is squeezed at the inner side of the screw hole 11, and a large friction force is generated between the screw hole 11 and the outer wall of the fixing piece 2, so that the fixing piece 2 is firmly fixed in the screw hole 11; the connecting part 32 of the sealing piece 3 is inserted into the fixing piece 2, the sealing piece 3 is fixed in the screw hole 11 through the friction force between the fixing piece 2 and the connecting part 32, and the shielding part 31 shields the screw hole 11 to play a role in beauty; when the sealing piece 3 needs to be detached, the sealing piece 3 only needs to be taken down from the fixing piece 2, and even if the sealing piece 3 is frequently detached, the screw hole 11 cannot be damaged; when the inside of mounting 2 appears damaging, only need take out mounting 2 from screw hole 11, change new mounting 2 can, not only the cost is lower, and it is very convenient to maintain.
As shown in fig. 1 and 3, a plurality of projections 21 are uniformly provided on the outer wall of the fixing member 2, and the outer ends of the projections 21 are pressed against the inner side of the screw holes 11.
Compared with the deformation which is easier to occur on the smooth outer wall, the lug 21 can conveniently load the fixing piece 2 into the screw hole 11, and the deformation generated by the lug 21 can extrude the outer wall of the fixing piece 2, so that a larger friction force is generated between the fixing piece 2 and the screw hole 11, and the fixing piece 2 is firmly fixed in the screw hole 11.
As shown in fig. 2 and 3, the fixing member 2 is made of an elastic plastic material, a fixing ring 22 is disposed on the inner side of the fixing member 2, at least two notches 23 are uniformly disposed on the fixing ring 22, a fastening ring 33 is disposed on the connecting portion 32 of the sealing member 3, the fastening ring 33 passes through the fixing ring 22, and the fixing ring 22 presses the fastening ring 33 in the fixing member 2.
When the sealing piece 3 needs to be installed in the screw hole 11, the sealing piece 3 only needs to be inserted into the fixing piece 2, when the retaining ring 33 presses the fixing ring 22, the fixing ring 22 is stressed and deforms and opens through the gap 23, then the retaining ring 33 passes through the fixing ring 22, and the fixing ring 22 presses the retaining ring 33 in the fixing piece 2; similarly, when it is desired to remove the closure 3, the closure 3 is simply pulled out with force, and the securing ring 22 is forced and deformed open through the gap 23, whereupon the retaining ring 33 can be removed from the securing member 2.
As shown in fig. 3, the projection 21 is disposed along the axial direction of the fixing member 2.
When the fixing part 2 is inserted into the screw hole 11, the projection 21 can play a role in guiding, and the fixing part 2 can be more easily installed into the screw hole 11 along the direction of the projection 21; on the contrary, if the projection 21 is formed to be perpendicular to the axial direction of the fixing member 2, a large resistance is applied to the fitting of the fixing member 2 into the screw hole 11, so that the fitting of the fixing member 2 into the screw hole 11 becomes difficult, and a friction force between the fixing member 2 and the screw hole 11 becomes too large to cause a problem that the removal of the fixing member 2 from the screw hole 11 becomes difficult.
The rear panel 1 is made of metal, and the sealing piece 3 is made of the same material as the rear panel 1.
The metal material has higher strength, protects the lock body by the back panel 1, and enables the back panel 1 to have better texture and better user experience by the metal; the sealing piece 3 is made of the same material as the rear panel 1, so that the integrity of the rear panel 1 is better, and the consistency of appearance and color is high.
The maximum outer diameter of the fixing member 2 is 2-3.5mm larger than the inner diameter of the screw hole 11.
The outer diameter of the fixing piece 2 is larger than the inner diameter of the screw hole 11, so that the fixing piece 2 can be fixed in the screw hole 11 through deformation and extrusion, and the fixing piece 2 is more firmly installed; if the difference between the maximum outer diameter of the fixing member 2 and the inner diameter of the screw hole 11 is smaller than 2mm, the friction force between the fixing member 2 and the screw hole 11 is insufficient, and the fixing member 2 is easily dropped out of the screw hole 11; when the difference between the maximum outer diameter of the fixing member 2 and the inner diameter of the screw hole 11 is larger than 3.5mm, the fixing member 2 is not only difficult to be fitted into the screw hole 11 but also difficult to be taken out of the screw hole 11 after being fitted into the screw hole 11, which causes inconvenience in subsequent maintenance.
The door lock with the screw hole 11 sealing structure of the door lock panel is an intelligent door lock.
The technical principle of the present invention is described above with reference to specific embodiments. The description is made for the purpose of illustrating the principles of the invention and should not be construed in any way as limiting the scope of the invention. Based on the explanations herein, those skilled in the art will be able to conceive of other embodiments of the present invention without any inventive effort, which would fall within the scope of the present invention.
