Description

A kind of laboratory return wind transom

Technical field

The utility model relates to the technical fields of laboratory ventilation, more particularly, to a kind of laboratory return wind transom.

Background technique

Return air inlet is that return air is used.One timing of indoor load, it is certain for needing the cold blast rate sent to interior.In summer, Indoor wind facies temperature for fresh air is generally lower, mixes into air-conditioning box with a small amount of fresh air so returning some wind using air -return duct Afterwards, be made cold wind be sent into it is indoor, relative to all with fresh air refrigerating wind for, can be effective energy saving.

The Chinese patent of existing Authorization Notice No. CN20513941U discloses a kind of return wind transom that filter effect is good, packet Forms and bottom frame are included, filter device are installed, the filter device is by the first filter screen, the second mistake between the forms and bottom frame Strainer and the adsorption layer composition between the first filter screen and the second filter screen, first filter screen are waveform, and its Both ends are provided with the plug-in card towards third filter screen, and the two sides of the third filter screen are provided with and the matched card slot of plug-in card.

It can adhere to after prior art among the above has the following deficiencies: return wind transom long-time use, on blinds big The dust of amount, the dust on blinds are inconvenient to clear up, and cause the return air effect of return air inlet bad, this problems demand solves.

Utility model content

The purpose of the utility model is to provide a kind of laboratory return wind transom, the work with dust on easy cleaning blinds With.

To achieve the above object, the utility model provides following technical solution:

A kind of laboratory return wind transom, including window frame are provided with blinds in the window frame, and sliding is provided with clear in the window frame The cleaning assemblies of clean blinds, the cleaning assemblies include the first cleansing tablet and link block, and first cleansing tablet is along link block Length direction is uniformly distributed, the link block length direction perpendicular to blinds arragement direction, the first cleansing tablet contact blinds Surface.

By using above-mentioned technical proposal, when accumulating many dusts on return wind transom, link block is first held, it is clear by several first Clean is placed on blinds surface, then pushes link block along blinds length direction, while the first cleansing tablet can follow link block edge Blinds length direction friction blinds, to play the role of blinds convenient for cleaning.

Further, the link block opens up sliding groove along its length, rotates and sets along its length in the sliding groove It is equipped with screw rod, sliding is provided with several second cleansing tablets in the sliding groove, and second cleansing tablet is threaded on screw rod.

By using above-mentioned technical proposal, the upper and lower surfaces of blinds can be infected with dust, in order to clear up simultaneously The upper and lower surface of blinds, rotation screw rod simultaneously drives the second cleansing tablet to draw close to the first cleansing tablet direction, when the first cleansing tablet and the When two cleansing tablets clamp blinds, then mobile link block, link block drives the first cleansing tablet and the second cleansing tablet friction blinds Upper and lower surface, to play the role of while clean blinds upper and lower surfaces.

Further, first cleansing tablet and the opposite one side of the second cleansing tablet are detachably provided with felt.

By using above-mentioned technical proposal, felt can adsorb tiny dust, from playing the role of deep layer cleaning blinds. But felt adsorbs the dust on blinds for a long time, the ability that felt absorbs dust can reach saturation state, felt is caused to adsorb Ability dies down, and is replaced with new felt as long as at this time removing felt, to play the role of that felt is made to continue to bond dust.

Further, it is provided with hook surface velcro on first cleansing tablet and the opposite face of the second cleansing tablet, it is described The one side of felt is provided with hair side velcro.

By using above-mentioned technical proposal, when needing to take off felt from the first cleansing tablet or the second cleansing tablet, It only needs operator to catch felt that firmly hair side velcro tears it down, similarly needs for felt to be mounted on the first cleaning When on piece or the second cleansing tablet, it is only necessary to press felt in the first cleansing tablet or the second cleansing tablet, to play The effect of felt easy to disassemble.

Further, one end that the screw rod stretches out link block is provided with switch block.

By using above-mentioned technical proposal, switch block can provide impetus for smooth screw rod, facilitate rotation to play The effect of screw rod, and then play the role of facilitating and adjust the second cleansing tablet position.

Further, the height that the window frame corresponds to switch block opens up recessing groove, and the recessing groove is opened along blinds length direction If.

By using above-mentioned technical proposal, recessing groove is opened up on window frame, link block may be mounted at the back of return wind transom at this time Face, to play the role of preventing interference personnel from walking.

Further, the link block internal screw thread is equipped with screw rod, and the screw rod is arranged along blinds length direction, shown silk The both ends rotary sleeve of bar, which is equipped with, places block, the one side placed block and be fixed on window frame, and rotation is embedded with snail in the placement block Wheel, the worm gear fixation are set on screw rod, and the worm gear side wall is engaged with worm screw, and the worm screw rotation is threaded through placement block It is interior.

By using above-mentioned technical proposal, when link block is mounted on the inner surface of window frame, when needing mobile link block, only Rotary worm is needed, worm screw drives worm gear rotation, and worm gear drives screw rod rotation, and screw rod drives link block to move along screw rod length direction It is dynamic, thus the convenient effect in window frame front mobile link block.

Further, one end of the worm screw is provided with rocking bar.

By using above-mentioned technical proposal, rocking bar can increase arm of force when worm screw rotation, and the arm of force increases, the drive of rotary worm Power is constant, and the active force being applied on rocking bar can be reduced, to play the role of facilitating rotary worm.

In conclusion the advantageous effects of the utility model are as follows:

1, the first cleansing tablet and link block are used, to generate the effect of easy cleaning blinds；

2, sliding groove, screw rod and the second cleansing tablet are used, to generate while clean the effect of two sides of blinds；

3, worm gear, worm screw, anti-stops and rocking bar are used, to generate the effect for being moved easily cleaning assemblies.
