DETAILED DESCRIPTION

[0033] In order to make the person skilled in the art better understand the technical scheme of the present application, the technical scheme in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by the person skilled in the art without creative labor should belong to the protection scope of the present application.

[0034] As shown in Figures 1-4 A threading hole cover, comprising a cover plate 1, and a threading cylinder 2 formed below the cover plate 1, a wire clamping cover 3 is arranged at the top opening of the threading cylinder 2, and a flexible adjusting piece 4 is detachably connected to the bottom of the threading cylinder 2, part of the flexible adjusting piece 4 extends obliquely towards the cover plate 1 side away from the outer wall of the threading cylinder 2, and specifically, as an example, the direction shown in Figure 2 The flexible adjusting piece 4 extends obliquely from bottom to top and from inside to outside, so as to form an expansion gap 5 between the outer wall of the threading cylinder 2 and the flexible adjusting piece 4. Under the action of external force, the flexible adjusting piece 4 deforms, and the size of the expansion gap 5 is variable. Specifically, under the extrusion of external force, the flexible adjusting piece 4 rotates clockwise, so that the expansion gap 5 becomes smaller. When the threading hole cover is placed on the desktop or the like, the threading cylinder 2 is inserted into the threading hole of the desktop, and at the same time, the flexible adjusting piece 4 is also extruded into the threading hole. No matter how much larger the inner diameter of the threading hole is than the threading cylinder 2, the flexible adjusting piece 4 can be abutted on the inner wall of the threading hole, so as to realize the stable assembly of the threading hole cover and the desktop threading hole. Since part of the flexible adjusting piece 4 extends obliquely, the expansion gap 5 between the flexible adjusting piece 4 and the outer wall of the threading cylinder 2 has a large range, the deformation of the flexible adjusting piece 4 is large after being extruded by external force, and then the adjustment range of the expansion gap 5 is large, so that the threading hole cover can adapt to threading holes with different sizes, and the installation adaptability of the threading hole cover is high.

[0035] As shown in Figure 4 The flexible adjusting piece 4 comprises a limiting section 41, an installation section 42 and a deformation section 43, the deformation section 43 is a closed U-shaped structure, the deformation section 43 and the installation section 42 form a V-shaped structure, the installation section 42 can be two parallel straight structures or two straight structures with an included angle, and the limiting section 41 is bent from the end of the installation section 42, and specifically, the two limiting sections 41 are bent from the end of the installation section 42 in directions away from each other.

[0036] As shown in Figure 3As shown, the threading cylinder 2 forms a mounting channel 21 and a fixed part, in the embodiment, the mounting channel 21 is located on the inner wall of the threading cylinder 2, the bottom of the mounting channel 21 is open for the elastic adjusting member 4 to be assembled into, and the side of the mounting channel 21 is open and arranged, specifically, the mounting channel 21 is formed by two L-shaped protrusions at a distance, and the open mouths of the two L-shaped protrusions are arranged opposite to each other, and the fixed part is a jack 24 formed by the absence of the part connecting the L-shaped protrusion and the inner wall of the threading cylinder 2, that is, the part section of the L-shaped protrusion is L-shaped, but not the entire length direction section. Of course, the jack 24 can be a hole with a size suitable for the section of the limiting section 41, or a slot larger than the section of the limiting section 41, and the specific limitation is not made.

[0037] When assembled, the limiting section 41 and the mounting section 42 of the elastic adjusting member 4 are inserted into the mounting channel 21 from bottom to top, at this time, an external force can be applied to extrude the two mounting sections 42 to reduce the distance therebetween, so as to facilitate the insertion into the mounting channel 21, once the limiting section 41 moves to the position of the jack 24 and extends into the jack 24, the limiting section 41 and the fixed part-jack 24 form a positioning and mounting cooperation, at this time, the elastic adjusting member 4 will not be separated from the threading cylinder 2.

[0038] In order to detach the elastic adjusting member 4 from the threading cylinder 2, the threading cylinder 2 further forms an unlocking window 23, the limiting section 41 is exposed in the unlocking window 23, so that an external force can be applied to compress the two limiting sections 41 opposite to each other, so as to facilitate the elastic adjusting member 4 to be separated from the mounting channel 21. In the embodiment, the unlocking window 23 is arranged in the area corresponding to the jack 24, in other words, the area of the jack 24 is expanded, so as to facilitate the contact with the limiting section 41 of the elastic adjusting member 4, or in other words, the contact with the limiting section 41 and the mounting section 42 of the elastic adjusting member 4, and then compress the two ends of the elastic adjusting member 4 opposite to each other to make the elastic adjusting member 4 deform.

[0039] In order to make the elastic adjusting member 4 deform more when extruded, the outer wall end face of the threading cylinder 2 forms a notch groove 25, the notch groove 25 extends along the axis direction of the threading cylinder 2, and part of the elastic adjusting member 4 is located in the notch groove 25, specifically, the intersection of the mounting section 42 and the deformed section 43 is located in the notch groove 25, so as to provide sufficient space for the deformed section 43 to deform more.

[0040] In order to better adapt to the desktop threading holes with different inner diameters, the number of the elastic adjusting member 4 can be one, two or more than two, when the number is two, the two are symmetrically arranged on the two sides of the radial direction of the threading cylinder 2, and when the number is three, the three are uniformly and spacedly arranged along the circumferential direction of the threading cylinder 2.

[0041] In order to facilitate processing, in the embodiment, the elastic adjusting member 4 is integrally bent by a steel wire, and has a shape similar to a "j" character.

[0042] As Figures 5-7 shown, different from the above structure, the card line cover 3 and the cover plate 1 are integrally arranged, the installation channel 21 is formed in the wall thickness inside of the threading drum 2, the unlocking window 23 is formed in the outer wall of the threading drum 2, the fixing part corresponding to the position of the unlocking window 23 is formed, which is the boss 22, that is, the fixing part is formed in the position corresponding to the unlocking window 23 of the installation channel 21, specifically, the boss 22 has the inclined guide surface 221 and the clamping surface 222 corresponding to the inclined guide surface 221, so as to Figure 5 As an example, the inclined guide surface 221 extends from bottom to top and from inside to outside, the clamping surface 222 can be a horizontal surface, or an inclined surface extending from top to bottom and from outside to inside, as long as the limiting section 41 can not easily separate from the boss 22, and then not easily separate from the installation channel 21.

[0043] As Figure 6 shown, the elastic adjusting part 4 includes the limiting section 41, the installation section 42 and the deformation section 43, the deformation section 43 is a closed U-shaped, the deformation section 43 and the installation section 42 form a V-shaped, the installation section 42 can be two parallel straight structures, or two straight structures with an included angle, the limiting section 41 is bent from the end of the installation section 42, specifically, two limiting sections 41 are bent from the end of the installation section 42.

[0044] When assembled, the limiting section 41 and the installation section 42 of the elastic adjusting part 4 are inserted into the installation channel 21 from bottom to top, the two limiting sections 41 slide against the inclined guide surface 221 and enter the clamping surface 222, because the distance between the clamping surface 222 and the bottom of the installation channel 21 is approximately equal to the width of the two limiting sections 41 side by side, so that the limiting section 41 is positioned and installed in cooperation with the boss 22, the elastic adjusting part 4 will not easily separate from the installation channel 21, and will not shake.

[0045] As Figure 10 shown, the two limiting sections 41 can not be arranged side by side, but on the same straight line, and the specific assembly is the same as the above embodiment, which will not be repeated here.

[0046] In the above three embodiments, the threading drum 2 is a closed circular ring, as Figure 8 , Figure 9 shown, in this embodiment, the threading drum 2 has an intermittent part 27 in the axial direction.

[0047] As Figure 11 , Figure 12As shown, in this embodiment, the installation channel 21 is formed inside the wall of the threading tube 2, and the unlocking window 23 is formed on the outer wall of the threading tube 2. However, no boss 22 is formed at the position of the unlocking window 23. The fixing part is the insertion hole 24, which is the insertion hole 24 that connects the unlocking window 23 and the installation channel 21.

[0048] During assembly, the limiting section 41 and the mounting section 42 of the elastic adjusting member 4 are inserted into the mounting channel 21 from bottom to top. At this time, external force can be applied to squeeze the two mounting sections 42 to reduce the distance between them, making it easier to insert into the mounting channel 21. Once the limiting section 41 moves to the position of the socket 24 and passes through the socket 24 into the unlocking window 23, the limiting section 41 and the fixing part-socket 24 form a positioning and mounting fit. At this time, the elastic adjusting member 4 will not detach from the threading tube 2.

[0049] Using tools, enter the unlocking window 23 and apply external force to the limiting section 41 to reduce the distance between the two installation sections 42. At the same time, apply external force to pull the elastic adjusting member 4 downward, and the limiting section 41 re-enters the installation channel 21. The elastic adjusting member 4 can then be detached from the threading tube 2.

[0050] like Figures 13-15 As shown, unlike the above embodiment, the limiting section 41 is formed by the wavy bending of the mounting section 42 itself, and the fixing part is the compression chamber 26 formed on the inner wall of the threading tube 2. The internal width of the compression chamber 26 is smaller than the maximum width of the limiting section 41. When an external force is applied to insert the limiting section 41 and the mounting section 42 into the compression chamber 26, the limiting section 41 deforms under the action of the external force. Specifically, the width decreases under the action of the inner wall of the compression chamber 26, so that the limiting section 41 can be forcibly inserted into the compression chamber 26. However, once the external force is stopped, the limiting section 41 returns to its original shape, that is, the limiting section 41 abuts against the inner wall of the compression chamber 26 to form a positioning and installation fit, so that the limiting section 41 and the mounting section 42 are firmly locked in the compression chamber 26, ensuring that the elastic adjusting member 4 will not fall off the threading tube 2.

[0051] When it is necessary to remove the elastic adjustment element 4 from the threading tube 2, an external force is applied to pull the limiting section 41 and the mounting section 42 downwards, so that it is removed from the compression chamber 26.

[0052] The above specific embodiments are used to explain and illustrate the present utility model, and are not intended to limit the present utility model. Any modifications and changes made to the present utility model within the spirit and scope of the claims shall fall within the protection scope of the present utility model.
