Description

The upper cover of the stack shell improved opens fixed structure

Technical field

The utility model refers to that a kind of upper cover of stack shell of improvement opens fixed structure, and wherein, this filter is that stack shell is provided with the technical field of opening rear fixing hypsokinesis angle for upper cover.

Background technology

First, refer to notification number: " No. M284433 ", patent name: shown in " filter cover structural improvement "; Wherein, description: refer to Fig. 3, Fig. 4, that there is above a cartridge filter 1 several locking bolt 4 and the round-meshed pin joint seat 2 of a tool, it also has that capping 20 closes, and capping 20 has several sealed seat 21 for sealed with locking bolt 4 and have the shape of falling L pin joint seat 22 for coordinating axle center 6 and combining with pin joint seat 2 pivot of cartridge filter 1; It is characterized in that: this capping 20 pin joint seat 22 is set as has strip hole 23, strip hole 23 for wear group axle center 6 and with cartridge filter 1 pin joint seat 2 pivot group one, this capping 20 pin joint seat 22 bottom is set as has longer oblique protuberance 24.

When opening capping 20: as Fig. 4 (A), be that each locking bolt 4 is loosened, and angle rotatable departing from capping 20, allowing capping 20 according to its pin joint seat 22 and the anglec of rotation, the open mode departing from cartridge filter 1 can be formed.And, following effect, advantage must be had: because capping 20 pin joint seat 22 is provided with longer oblique protuberance 24, therefore when capping 20 rotates over 90 degree, namely oblique protuberance 24 can conflict cartridge filter 1 stack shell, formation makes capping 20 in nearly plumbness, and do not have the problem excessively opened, therefore can obtain effect of " revolution space that reduction is opened is convenient to small space and opens ", " accidentally not making capping clash into stack shell because excessively opening ".

When covering capping 20: as Fig. 4 (B), capping 20 can be rotated and be covered on cartridge filter 1, then make locking bolt 4 be sleeved on sealed seat 21 to give locking.Above-mentioned, there is following effect, advantage: because capping 20 pin joint seat 22 establishes strip hole 23 to wear group axle center 6, therefore strip hole 23 is " vertically " state when covering, therefore, when locking locking bolt 4, make capping 20 in declining again vertically downward, and be decline simultaneously vertical in circle, therefore the effect all sealed can be pressed.

But this capping 20 coordinates according to oblique protuberance 24: pin joint seat 22 and strip hole 23 are organized axle center 6 and controlled capping 20 and maintain in capping 20 and lift rear position with wearing.Then, use with use after cartridge filter 1 in press all bigger than normal, therefore, capping 20 all requires that weight lays particular stress on making because of intensity, and the strip hole 23 of capping 20 organizes the sliding combo in axle center 6 and connect with wearing, cause, wear group axle center 6 and must bear capping 20 weight simultaneously, and the fail in shear that capping 20 weight is brought, and sliding friction destruction of joining, it can thus be appreciated that, wear group axle center 6 inevitable restricted lifetime in this implements, and coordinate the associated components wearing group axle center 6 also to have bigger than normal, waste material and resource situation.

In view of this, the present inventor deeply probes into for wearing group axle center 6 association area that can increase the service life, and after continuous research and development and amendment, the phase is to solve the problem.

In view of the above, learn that existing to wear group axle center be only that service life is limited, therefore, impel the present inventor towards the direction research and development that increase the service life, and in many ways to think deeply via inventor, then think and, be best mode according to connecing without sliding combo.

Utility model content

Technical problem underlying to be solved in the utility model is, overcomes the above-mentioned defect that prior art exists, and provides a kind of upper cover of stack shell of improvement to open fixed structure, and this filter is provided with stack shell to open rear fixing hypsokinesis angle for upper cover.

The utility model solves the technical scheme that its technical problem adopts:

The upper cover of the stack shell of improvement opens a fixed structure, have a room, and stack shell top side has the upper cover of closed room in the stack shell that this filter uses; Then, on rear side of stack shell, be provided with directed lug, there is on rear side of directed lug an abutting part; Upper cover outside back is provided with and pastes the upper cover ear of directed lug, upper cover ear upper limb is flat to be had one and revolves relying part, then, on be placed on the spin axis that upper cover ear is equipped with the directed lug of pivot joint, and upper cover integrally has the pulling part protracted, and pulling part is used for that upper cover opens, hypsokinesis departs from stack shell top side, make room remove close, meanwhile, the upper cover opened contact for revolving relying part according to abutting part fixed position and the angle of stack shell, control upper cover slightly hypsokinesis on rear side of stack shell.

Wherein, directed lug arranged side by side is equipped with again on rear side of this stack shell, directed lug has crossed the first pivot hole, in addition, directed lug left and right side again and post this upper cover ear, upper cover ear has additional the second pivot hole of corresponding first pivot hole, and the first pivot hole and the second pivot hole are equipped with this spin axis, then, flat between upper cover ear and another upper cover ear have this and revolve relying part, revolve and be separately formed with one with the upper cover ear of left and right side on rear side of relying part and revolve relying part groove, revolve that relying part groove opens in upper cover, hypsokinesis time to splice directed lug; Again when the abutting part fixed position of the upper cover opened according to stack shell contacts for revolving relying part with angle, accordingly, control upper cover hypsokinesis and stack shell top side keep the fixed angle position between 95 ° to 135 °.

So as to upper setting, the utility model filter runs through upper cover ear and directed lug in spin axis, moreover, the upper cover opened contacts for revolving relying part with angle according to the abutting part fixed position of stack shell, and accordingly, control upper cover hypsokinesis and stack shell top side keep the fixed angle position between 95 ° to 135 °, this spin axis only wears merely upper cover ear and directed lug, therefore without the need to existing disappearance of worrying, in addition, upper cover can utilize the abutting part of small size and revolve the benefit that relying part controls hypsokinesis angle.

The beneficial effects of the utility model are, this filter is provided with stack shell to open rear fixing hypsokinesis angle for upper cover.
