Abstract

The utility model discloses a screen cloth fastening structure. The screen cloth fastening structure mainly comprises an upper ring and a lower ring, wherein a first-level step and a second-level step are formed on the upper ring, a first-level step and a second-level step are correspondingly formed on the lower ring, a tip portion is formed on the second-level step of the upper ring, a groove is correspondingly formed in the first-level step of the lower ring, the tip portion is inserted into the groove, and the second-level step of the lower ring and the first-level step of the upper ring are buckled. According to the screen cloth fastening structure, extra manpower used for tensioning screen cloth and carrying out fixation is not needed, manpower is saved, and efficiency is improved; the tensioning degree of the screen cloth can be conveniently adjusted as needed; meanwhile, when the screen cloth is locked, a certain adjusting space can be reserved; after the screen cloth is used for some time and becomes loose, the screen cloth can be tensioned again only by locking bolts again, so that frequency of disassembly is reduced.

Description

A kind of screen cloth fastening structure

Technical field

The utility model relates to a kind of auxiliary equipment of rubber processing, refers in particular to a kind of screen cloth fastening structure.

Background technology

As shown in Figure 1, a kind of screen cloth fastening structure 100 of prior art, is comprised of pressed on ring 101, lower ring 102 and bolt 103, and bolt 103 is locked screen cloth through pressed on ring 101 and lower ring 102 successively.When locking screen cloth, pressed on ring 101 and lower ring 102 are directly to pressing, and it is all horizontal plane to pressure surface.Its defect is, screen cloth is comparatively difficult for tensioning, needs manually by after screen cloth tensioning, just can fix by above bolt, and, due to screen cloth stressed after its wire side easily lax, the effect that makes to sieve is influenced; On the other hand, when the lax fastening again of screen cloth, clamping screw after necessary completely knocked down re-tensioning screen cloth, wastes time and energy, and cannot carry out according to need degree of tightness adjustment.

As shown in Figure 2, the another kind of screen cloth fastening structure 200 of prior art, is comprised of upper latch notch 201 and the lower bayonet socket 202 of permanent deformation, and screen cloth is fastened between upper latch notch 201 and lower bayonet socket 202.This screen cloth fastening structure is tensioning screen cloth face better, yet owing to adopting permanent deformation bayonet socket, therefore, uses after a period of time, and screen cloth face cannot carry out tensioning when lax again, also cannot carry out according to need degree of tightness adjustment.

In view of the above-mentioned defect of prior art screen cloth fastening structure, the inventor develops a kind of screen cloth fastening structure that overcomes above-mentioned defect, and this case produces thus.

Utility model content

The purpose of this utility model is to provide a kind of and saves manpower and raise the efficiency and screen cloth fastening structure easy to use.

For reaching above-mentioned purpose, solution of the present utility model is:

A fastening structure, is mainly comprised of pressed on ring and lower ring, and pressed on ring forms one-level step and two stage steps, and lower ring also forms one-level step and two stage steps accordingly; In pressed on ring two stage steps, form tip, and on lower ring one-level step, form accordingly groove, groove is inserted in tip; And the one-level step of the two stage steps of lower ring and pressed on ring fastens.

Further, also comprise bolt, screw bolt passes pressed on ring tip and lower circular groove groove are by pressed on ring and lower ring pressing.

Further, both sides, pressed on ring tip form plane, and the corresponding plane that forms in lower circular groove groove both sides.

Adopt after such scheme, when the utility model is used, screen cloth is placed between pressed on ring and lower ring, and then, the groove of lower ring is inserted in the tip of pressed on ring, and meanwhile, the one-level step of the two stage steps of lower ring and pressed on ring fastening, by screen cloth tensioning and install.Compared with prior art, have the following advantages:

One, by the tip of pressed on ring and the groove of lower ring, by screen cloth tensioning, without a large amount of manpowers of cost, go tensioning screen cloth to be fixed again, save manpower and raise the efficiency.

Two, by the tip of pressed on ring and the groove of lower ring, coordinate tensioning screen cloth, its tensioning degree can regulate as required.

Meanwhile, when locking screen cloth, can reserve certain adjusting space, after screen cloth is used a period of time to occur relaxing, as long as clamping screw can, to screen cloth tensioning again, reduce the frequency of dismounting once again.

The specific embodiment

Below in conjunction with drawings and the specific embodiments, the utility model is elaborated.

Consult shown in Fig. 3 to Fig. 6, a kind of screen cloth fastening structure that the utility model discloses, is mainly comprised of pressed on ring 1 and lower ring 2.

Pressed on ring 1 forms one-level step 11 and two stage steps 12, and lower ring 2 also forms one-level step 21 and two stage steps 22 accordingly.In the present embodiment, the material of pressed on ring 1 and lower ring 2 is all aluminium.

In pressed on ring 1 two stage steps 12, form tip 13, and on lower ring 2 one-level steps 21, form accordingly groove 23, groove 23 is inserted in tip 13, and meanwhile, the two stage steps 22 of lower ring 2 fastens with the one-level step of pressed on ring 1 11.

As shown in Figure 6, the utility model also comprises bolt 3, and bolt 3 passes pressed on ring 1 tip 13 and lower ring 2 grooves 23 successively by pressed on ring 1 and lower ring 2 pressings.

In the present embodiment, 13 both sides, pressed on ring 1 tip form plane, and the lower ring 2 corresponding planes that form in groove 23 both sides.

As shown in Figures 5 and 6, during fastening screen cloth, directly screen cloth 4 is divided on lower ring 2, pressed on ring 1 is directly placed on lower ring 2, and tip 13 is inserted groove 23 and by screen cloth 4 tensionings, then locked bolt 3.Due to coordinating of groove 23 and tip 13, when pressed on ring 1 presses down, force screen cloth 4 to form bending states, now, pressed on ring 1 tip is pressed in screen cloth 4 bending places for 13 times, and tip 13 and the frictional force of screen cloth 4 are increased.Meanwhile, 13 both sides, pressed on ring 1 tip form plane, and lower ring 2 groove 23 both sides are the corresponding plane that forms also, and along with the compression of pressed on ring 1, the plane of the plane of 13 both sides, tip and groove 23 both sides fastens, and screen cloth 4 is produced to larger tension.Further, the two stage steps 22 of lower ring 2 fastens with the one-level step of pressed on ring 1 11, screen cloth 4 is lengthened in the length of pressed on ring 1 and 2 windings of lower ring, and form the tension to screen cloth.

The foregoing is only an embodiment of the present utility model, the not restriction to this case design, all equivalent variations of doing according to the design key of this case, all fall into the protection domain of this case.
