Abstract

The utility model discloses a coating liquid filter end-cover locking fastener. A screw is arranged in the center of a handle. An upper cam is arranged on the outer wall of an upper sleeve and a lower cam is arranged on the outer wall of a lower sleeve. The corresponding outer wall of the lower cam on the lower sleeve is an inwardlydished arc surface and the inner hole of the lower sleeve is the bolt hole. Two ends of a connection rod are respectively hinged with the upper cam and the lower cam by two pin axles. The screw passes through the through hole of the upper sleeve and screwed in the screw hole of the lower sleeve. When the locking fastener is arranged in a closed filter and the end-cover is conveniently disassembled and assembled and the filter vat is conveniently cleaned. The circle of the end-cover is uniformly strained. The end-cover seal is good and the coating liquid is prevented from being leaked in the filter.

Description

Masking liquid filter end cap tight locking button

Technical field

The utility model relates to a kind of masking liquid filter end cap tight locking button.

Background technique

For obtaining good coating, general masking liquid need filter through filter, goes small amount of impurities in the masking liquid with worry, as the insulation coating on electric steel surface, as without filtration, then may produce the holiday phenomenon, has a strong impact on the electrical steel product quality.

Usually can fix by plain bolt and nut between filter and the end cap, consider that operator need online switching to clean the self-filtering bucket and be coated with liquid filter, and shorten and simplification filter dismounting time and difficulty, filter end cap and filter fixedly select the complete use of wing nut fitted bolt for use, wing nut is than the plain nut dismounting of being more convenient for.But in actual use thereafter, still there are defective in wing nut and bolt, mainly show as wing nut and tighten difficulty, do not have supporting special tool; The control of end cap periphery impacting force is bad, often causes end caps to leak masking liquid; End cap periphery wing nut is fastening when inhomogeneous, causes end cap inner seal rings unbalance stress and ruptures, and causes masking liquid to overflow.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of masking liquid filter end cap tight locking button, this tight locking button can conveniently be implemented the dismounting of end cap in close filter, made things convenient for the cleaning of filter vat, the end cap periphery is stressed evenly, end bracket enclosed is good, has avoided the leakage of masking liquid in the filter.

For solving the problems of the technologies described above, the utility model masking liquid filter end cap tight locking button comprises handle, screw rod, upper bush, lower sleeve, upper protruding block, lower protruding block, connecting rod and two bearing pins, described screw rod is vertical at described handle center, described upper protruding block is located at described upper bush outer wall, described lower protruding block is located at described lower sleeve outer wall, the corresponding outer wall that described lower sleeve is provided with lower protruding block is the arc surface of indent, the endoporus of described lower sleeve is a screw, described connecting rod two ends are articulated in described upper protruding block and lower protruding block respectively by described two bearing pins, and described screw rod is twisted in the screw of described lower sleeve after passing the through hole of described upper bush.

Stressed evenly for the dismounting and the feel that make things convenient for this tight locking button, above-mentioned handle adopts quincunx handle.

Because the utility model masking liquid filter end cap tight locking button has adopted technique scheme, be that screw rod is located at handle center, the upper bush outer wall is provided with upper protruding block, the lower sleeve outer wall is provided with lower protruding block, the corresponding outer wall that lower sleeve is provided with lower protruding block is that the arc surface and the lower sleeve endoporus of indent is screw, the connecting rod two ends are articulated in upper protruding block and lower protruding block respectively by two bearing pins, and screw rod is twisted in the screw of lower sleeve after passing the upper bush through hole; This tight locking button can conveniently be implemented the dismounting of end cap in close filter, made things convenient for the cleaning of filter vat, and the end cap periphery is stressed, and evenly end bracket enclosed is good, has avoided the leakage of masking liquid in the filter.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and embodiments:

Fig. 1 is the structural representation of the utility model masking liquid filter end cap tight locking button,

Fig. 2 is the schematic representation of this tight locking button locking filter end cap.

Embodiment

As shown in Figure 1, the utility model masking liquid filter end cap tight locking button comprises handle 1, screw rod 2, upper bush 3, lower sleeve 4, upper protruding block 5, lower protruding block 6, connecting rod 7 and two bearing pins 8, described screw rod 2 is vertical at described handle 1 center, described upper protruding block 5 is located at described upper bush 3 outer walls, described lower protruding block 6 is located at described lower sleeve 4 outer walls, the corresponding outer wall that described lower sleeve 4 is provided with lower protruding block 6 is the arc surface 42 of indent, the endoporus of described lower sleeve 4 is screws 41, described connecting rod 7 two ends are articulated in described upper protruding block 5 and lower protruding block 6 respectively by described two bearing pins 8, and described screw rod 2 is twisted in the screw 41 of described lower sleeve 4 after passing the through hole of described upper bush 3.

Stressed evenly for the dismounting and the feel that make things convenient for this tight locking button, above-mentioned handle 1 adopts quincunx handle.

As shown in Figure 2, when close filter end cap 12, upper edge 11 with the interior concaved circular cambered surface applying filter cylinder 10 of the lower sleeve 4 of this tight locking button, upper bush 3 is positioned on the end cap 12, screw rod is twisted in the screw of lower sleeve 4 after penetrating endoporus, end cap 12 through holes and filter cylinder bead 11 through holes of upper bush 3, and utilize plum blossom handle 1 to screw screw rod, screw rod drives plum blossom handle 1 and exerts pressure to upper bush 3, because upper bush 3 is hinged by connecting rod 7 with lower sleeve 4, the pressure of upper bush 3 lower sleeve 4 against under act on the end cap 12 and make filter airtight; Can all establish three or four these tight locking buttons at end cap 12 peripheries, screw screw rod by handle 1 and end cap 12 can be anchored on the filter cylinder 11 also by the seal ring close filter; Owing to adopt plum blossom handle 1 turn screw rod, the stressed degree of perception screw rod preferably makes end cap 12 stressed evenly, under the prerequisite that guarantees end bracket enclosed, has avoided seal ring stressed irregular and damage; When the dismounting end cap, screw out screw rod by plum blossom handle 1 and can open end cap 12, made things convenient for the cleaning of filter inner filtration bucket.This tight locking button has overcome the defective of wing nut, makes the end cap dismounting more convenient, efficient, under the prerequisite that guarantees the filter sealing, has avoided the damage of seal ring.
