Abstract

The utility discloses a wheel device of a dehumidifier. The wheel device comprises a wheel and a plurality of positioning rods limiting the wheel circumferentially, the wheel is arranged between an upper aluminum cover and a lower aluminum cover, the upper and lower ends of the positioning rods are fixed to the upper and lower aluminum covers, the lower ends of the positioning rods are provided with threaded portions. The threaded portions penetrate through the lower aluminum cover and are clamped and fixed on the lower aluminum cover through two nuts with gaskets. The lower aluminum cover is firmly clamped through the nuts with gaskets, and two fastened surfaces of the lower aluminum cover are provided with sufficient fixing sides. Cost is reduced, processing period is shortened, performance of the positioning rods can be developed sufficiently, and the service life of the wheel device is prolonged.

Description

The rotary wheel device of dehumidifier

Technical field

The utility model relates to dehumidifier, is specifically related to the rotary wheel device of dehumidifier.

Background technology

Each part of the internal portion of low dew point dehumidifying unit requires sealing relatively strict, and it is no exception as its sealing of runner of rotary dehumidifier internal core, dehumidifying unit vertical runner is except the use encapsulant seals, runner is also very crucial with the concentric fit of retaining element up and down, and it is suitable important that the location of runner just seems.

As shown in Figure 1, in existing dehumidifier rotary wheel device, runner 1 is arranged between the upper and

lower aluminium lid

11,12, adopt 2 pairs of runners of four backstays 1 of circumferential arrangement quadrate to carry out circumferentially spacing, runner 1 is spacing following 11,12 and four backstays 2 of upper and lower aluminium lid, rotates around its axle center.

Usually, backstay 2 be designed to a round bar, compartment of terrain is set with on it, lower bearing 21, and pass through jump ring 22 respectively with bearing fixing, the upper end of backstay 2 pass aluminium lid 11 and utilize spring 23 and nut fastening, the lower end of backstay 2 be fixed on down on the aluminium lid 12 and need thereon below be fixedly clamped, see also Fig. 2 again, at present backstay 2 with the fixing means of following aluminium lid 12 is: at the external part of backstay 2 nut of screwing on, iron hoop 3 of welding is perhaps fixed an iron hoop 3 with a pin 4 on the upper surface of following aluminium lid 12, and this scheme has increased the metal cutting amount of parts, prolonged the process-cycle, in addition, the electric welding meeting causes iron hoop 3 changes to be quenched, and bearing capacity descends, under the situation that runner 1 moves repeatedly, iron hoop 3 is cracked easily, makes backstay 2 can not obtain effectively fastening and positioning action, runner 1 off normal occurred, thereby make be mated on, following

aluminium lid

11,12 dislocation do not reach the effect of sealing.

The utility model content

Technical problem to be solved in the utility model is the fixed form complexity that solves backstay in the dehumidifier rotary wheel device, processing cost height, the problem that service life is short.

In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted provides a kind of rotary wheel device of dehumidifier, comprise runner and described runner is carried out circumferentially spacing a plurality of backstays, described runner is arranged between the upper and lower aluminium lid, the upper and lower end of described backstay is separately fixed on the described upper and lower aluminium lid, it is characterized in that, the lower end of described backstay is provided with the threaded portion, and described threaded portion is run through described aluminium lid down and is with the nut clip of pads to fasten on described aluminium lid down by two.

In the rotary wheel device of above-mentioned dehumidifier, described nut and pad are as a whole.

The rotary wheel device of the dehumidifier that the utility model provides, to descend aluminium lid to clamp firmly by the nut of band pad, and on two fastening faces of following aluminium lid, enough stationary planes are arranged, when having reduced cost and having shortened the process-cycle, the performance of backstay has been given full play to, prolonged its service life.

Description of drawings

Fig. 1 is existing dehumidifier rotary wheel device structural representation;

Fig. 2 is the A portion enlarged drawing among Fig. 1;

The dehumidifier rotary wheel device structural representation that Fig. 3 provides for the utility model;

Fig. 4 is the B portion enlarged drawing among Fig. 3.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is made detailed explanation, in the following introduction, adopted identical label with parts identical in the rotary wheel device of Fig. 1, existing dehumidifier shown in Figure 2.

As shown in Figure 3, Figure 4, the rotary wheel device of the dehumidifier that the utility model provides, comprise runner 1 and runner 1 is carried out circumferentially spacing a plurality of backstays 2, backstay 2 is four and along the circumferential uniform setting of runner 1 in the present embodiment, the compartment of terrain is set with upper and lower bearing 21 on the backstay 2, and passes through jump ring 22 respectively with bearing fixing.Runner 1 is arranged between the upper and

lower aluminium lid

11,12, the upper end of backstay 2 pass aluminium lid 11 and utilize spring 23 and nut fastening, the lower end of backstay 2 is provided with the threaded portion, aluminium lid 12 is down run through in the threaded portion, and be fixedly clamped on following aluminium lid 12 by two nuts 5, be respectively equipped with pad 6 between nut 5 and the following aluminium lid 12.Obviously, can nut 5 and pad 6 can adopt integrative-structure.

The rotary wheel device of the dehumidifier that the utility model provides, nut 5 by band pad 6 will descend aluminium lid 12 to clamp firmly, and on two fastening faces of following aluminium lid, enough stationary planes are arranged, iron hoop and electric welding have been saved, simplified processing technology, when having reduced cost and having shortened the process-cycle, the performance of backstay 2 has been given full play to, prolonged service life.

The utility model is not limited to above-mentioned preferred forms, and anyone should learn the structural change of making under enlightenment of the present utility model, every with the utlity model has identical or close technical scheme, all fall within the protection domain of the present utility model.

Claims
