Description

Technical Field

[0001] The invention relates to a constant-temperature metering box and a use method thereof, belonging to the field of metering boxes. Background Art

[0002] In the northern region, the temperature difference between the four seasons is large. Although the meter box installed outdoors is equipped with heat dissipation holes for heat dissipation in summer, in winter, the outside cold air can also enter the meter box through the heat dissipation holes, causing the internal temperature to be too low, affecting the service life of the internal components. In addition, the dustproof effect of the common meter boxes on the market is not ideal, so it is necessary to improve it. Summary of the invention

[0003] The purpose of the present invention is to solve the above problems existing in the background technology and to provide a constant temperature metering box and a method of using the same.

[0004] The present invention achieves the above-mentioned purpose by adopting the following technical solutions:

[0005] A constant temperature metering box, comprising a door and a box body; the box body comprises an outer box body and an inner box body fixedly connected to the inner part of the outer box body; a U-shaped gap is left between the outer box body and the inner box body; a door is hinged on the side of the outer box body; a U-shaped groove is provided on the door; a movable device, a transmission device and a sliding device are symmetrically provided in the groove; an air inlet I is provided at the bottom end of the side of the outer box body; an air inlet II is provided at the top end of the side of the inner box body, and a dustproof net is provided on the air inlet II.

[0006] A method for using a constant temperature metering box, characterized in that the method comprises the following steps:

[0007] Step 1: Rotate the door, and drive the rotating plate connected to it to rotate through the door, so that the movable device, the transmission device and the sliding device move into the gap, and then rotate another rotating plate to make it close to the door, and then lock it;

[0008] Step 2: When the external wind force cannot blow the slider, the external air enters the gap through the air inlet I, then moves to the top of the slider through the gap left by the slider arc surface, and finally passes through the dustproof net and the air inlet II into the inner box to cool down;

[0009] Step 3: When the external wind blows the slider upward, the slider drives the transmission block II to move through the plug rod, thereby connecting the perforations I and II, so that the external air enters the gap through the air inlet I, moves upward, then passes through the gap left by the slider arc surface, and finally is discharged from the exhaust hole. When it flows through the air inlet II, due to the high flow rate in the gap, the hot air in the inner box is extracted to cool down.

[0010] Step 4: In winter, insert the rod into the through hole at the top. When the slider moves upward due to the external wind, the rod drives the transmission block II to move, thereby connecting the perforations I and II, so that the outside air enters the gap through the air inlet I, moves upward, then passes through the gap left by the slider arc surface, and finally is discharged from the exhaust hole. The slider blocks the air inlet II to prevent internal heat loss.

[0011] Compared with the prior art, the present invention has the following beneficial effects: the present invention not only has a heat preservation effect, maintains a constant temperature, and avoids affecting the service life of components, but also has the function of cleaning dust on the dustproof net, avoiding clogging of the dustproof net and affecting heat dissipation.

Obviously, the described embodiments are only part of the embodiments of the invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0025] When the door 1 is closed, the movable device 3 , the transmission device 4 and the sliding device 5 are all located in the gap 28 .

[0026] The movable device 3 includes a fixed plate 36 and a movable plate 33; the fixed plate 36 is fixedly connected at the corner of the groove 11, and a perforation Ⅰ37 is provided on the fixed plate 36; the movable plate 33 is arranged at the lower end of the fixed plate 36, and the side of the movable plate 33 away from the corner of the groove 11 is fixedly connected to the elastic telescopic rod 32; the fixed end of the elastic telescopic rod 32 is fixedly connected to the fixed plate 31; the fixed plate 31 is fixedly connected in the groove 11; the movable plate 33 is provided with an inclined surface on the side close to the corner of the groove 11, and a T-shaped slide groove 35 is provided on the inclined surface, and a perforation Ⅱ34 is also provided on the movable plate 33; when the door 1 is closed, the fixed plate 36 and the movable plate 33 separate the vertical space of the gap 28 from the horizontal space. The top of the gap 28 forms a sealed cavity, which is beneficial to keep the temperature constant.

[0027] The transmission device 4 includes a transmission rod 41; a transmission block I 42 is fixedly connected to the lower end of the transmission rod 41, a transmission block II 45 is fixedly connected to the upper end of the transmission rod 41, and two horizontal through holes 44 are also provided on the transmission rod 41; a plug rod 43 is provided in the through hole 44 to slide with it; the transmission block II 45 contacts the inclined surface on the movable plate 33, and a T-shaped slider 46 is fixedly connected to the side of the transmission block II 45 close to the inclined surface to slide with the T-shaped slide groove 35. By adjusting the position of the plug rod 43, the air flow mode during heat dissipation can be changed in summer or the heat loss can be reduced in winter, which is easy to remove dust and helps to keep the temperature constant in winter.

[0028] The sliding device 5 includes a slider 51; a vertical slideway Ⅰ57 is provided on the slider 51 to slide with the transmission rod 41, and a transmission block Ⅰ42 is located at the lower end of the slider 51; the slider 51 slides with the gap 28 and the groove 11; one end corner of the slider 51 is set to be arc-shaped, and an airbag 52 is fixedly connected to the upper end of the slider 51, and a vertical slideway Ⅱ is also provided on the slider 51; a connecting rod 54 is provided in the slideway Ⅱ to slide with it; a quadrangular pyramid-shaped pressing block 53 is fixedly connected to the upper end of the connecting rod 54, and a flat plate 55 is fixedly connected to the lower end of the connecting rod 54; a slot 56 is provided at the lower end of the slider 51 to slide with the flat plate 55. When the door 1 is opened, the flat plate 55 and the transmission block Ⅰ42 are placed on the lower end surface of the groove 11. Affected by the wind, the flat plate 55 moves upward first, reducing the contact between the airbag 52 and the inner box 25, thereby reducing the friction between the two. Then the slider 51 moves upward. When moving downward, the pressure block 53 pushes the airbag 52 to deform, increasing the friction between the inner box 25 and the airbag 52, and slowing down the falling speed.

[0029] A plurality of partition plates 22 are fixedly connected to the bottom of the gap 28 between the outer box 21 and the inner box 25; a notch is provided on the side of the outer box 21, and a rotating plate 24 is hinged at the notch, one of the rotating plates 24 being hinged to the door 1. The bottom of the gap 28 also forms a sealed cavity, and the arrangement of the rotating plate 24 facilitates the installation of the movable device 3, the transmission device 4 and the sliding device 5 into the gap 28 when the door 1 is closed, and when the door 1 is opened, the movable device 3, the transmission device 4 and the sliding device 5 are separated from the gap 28 together with the door 1, so that the movable device 3, the transmission device 4 and the sliding device 5 can be maintained or the dust screen 26 can be manually cleaned.

[0030] An exhaust hole 29 is disposed at the top of the outer box body 21 ; when the fixing plate 36 is located inside the gap 28 , the through hole I 37 is connected to the exhaust hole 29 .

[0031] When the transmission block II 45 moves upward, it pushes the movable plate 33 to compress the elastic telescopic rod 32 and connects the through hole II 34 with the through hole I 37 .

[0032] The arc portion of the slider 51 allows gas to circulate, and when the slider 51 moves to the position of the air inlet II 27 , the slider 51 seals the air inlet II 27 .

[0033] A method for using a constant temperature metering box, characterized in that the method comprises the following steps:

[0034] Step 1: Rotate the door 1, and drive the rotating plate 24 connected thereto to rotate, so that the movable device 3, the transmission device 4 and the sliding device 5 move into the gap 28, and then rotate another rotating plate 24 to make it close to the door 1, and then lock it;

[0035] Step 2: When the external wind force cannot blow the slider 51, the external air passes through the air inlet I 23 into the gap 28, then passes through the gap left by the curved surface of the slider 51 to move to the top of the slider 51, and finally passes through the dustproof net 26 and the air inlet II 27 to enter the interior of the inner box 25 to cool down;

[0036] Step 3: When the external wind blows the slider 51 upward, the slider 51 drives the transmission block II 45 to move through the insertion rod 43, thereby connecting the perforations I 37 and II 34, so that the external air enters the gap 28 through the air inlet I 23, moves upward, then passes through the gap left by the arc surface of the slider 51, and finally is discharged from the exhaust hole 29. When it flows through the position of the air inlet II 27, due to the high flow rate in the gap 28, the hot air in the inner box 25 is extracted to cool down;

[0037] Step 4: In winter, insert the rod 43 into the through hole 44 at the top. When the slider 51 is moved upward by the external wind, the transmission block Ⅱ45 is driven to move by the rod 43, thereby connecting the perforations Ⅰ37 and Ⅱ34, so that the outside air enters the gap 28 through the air inlet Ⅰ23, moves upward, and then passes through the gap left by the arc surface of the slider 51, and finally is discharged from the exhaust hole 29. The slider 51 blocks the air inlet Ⅱ27 to prevent internal heat loss.

[0038] The working principle of the present invention is: when using the device, the door 1 is rotated, and the rotating plate 24 connected thereto is driven to rotate by the door 1, so that the movable device 3, the transmission device 4 and the sliding device 5 are moved into the gap 28, and then another rotating plate 24 is rotated to make it close to the door 1, and then the rotating plate 24 is connected to the door 1 through the lock buckle and the lock tongue;

[0039] When used in summer, the insertion rod 43 is inserted into the through hole 44 below;

[0040] When the external wind force is weak and cannot blow the slider 51, the external air enters the gap 28 through the air inlet Ⅰ 23, then passes through the gap between the curved surface of the slider 51 and the inner box 25 to move to the top of the slider 51, and finally passes through the dustproof net 26 and the air inlet Ⅱ 27 to enter the inner box 25 to cool down.

[0041] When the external wind force increases and blows the slider 51 upward, the flat plate 55 is blown upward into the card slot 56 by the wind, and the pressure block 53 is driven upward by the connecting rod 54, so that the pressure block 53 no longer squeezes the air bag 52, and the air bag 52 returns to its original state and only contacts with the outer wall of the inner box body 25 to reduce friction. Then the slider 51 moves upward, and after moving to contact with the insertion rod 43, the transmission rod 41, the transmission block I 42, and the transmission block II 45 are driven upward by the insertion rod 43. The transmission block II 45 moves upward and pushes the inclined surface of the movable plate 33, so that the movable plate 33 moves horizontally and compresses the elastic telescopic rod 32, thereby connecting the perforation I 37 and the perforation II 34. At this time, the slider 51 is located below the air inlet II 27. After the external air enters the gap 28 through the air inlet I 23, it moves upward, and then passes through the gap left between the arc surface of the slider 51 and the inner box body 25, and is finally discharged from the exhaust hole 29. Since the gap between the arc surface of the slider 51 and the inner box body 25 is smaller than The cross-section of the gap 28 increases the flow rate of the gas, and then when the air flows through the position of the air inlet Ⅱ27, the pressure in the gap 28 is reduced, and then the hot air in the inner box 25 is extracted to cool down; at the same time, because the hot air of the inner box 25 flows into the gap 28 at this time, the dust attached to the outside of the dustproof net 26 can be driven to separate from the dustproof net 26, thereby reducing the dust on the dustproof net 26 and reducing blockage; after the wind stops, the pressing block 53 moves downward under the action of gravity, causing the airbag 52 to deform, and then fully contact with the outer wall of the inner box 25, increasing the friction force and slowing down the downward movement speed. When the wind blows the slider 51 upward, the moving stroke of the slider 51 is reduced, so that the perforation Ⅰ37 and the perforation Ⅱ34 can be quickly connected, avoiding the situation that when the perforation Ⅰ37 and the perforation Ⅱ34 are not connected, the strong wind from the outside carries a large amount of dust and blows it into the inner box 25, causing a large amount of dust to adhere to the dustproof net 26, increasing the probability of clogging the dustproof net 26;

[0042] In winter, the rod 43 is inserted into the through hole 44 located at the top. When the slider 51 is moved upward by the strong wind from the outside, it contacts the rod 43 located at the high position, and drives the transmission block II 45 to move through the rod 43, thereby connecting the through hole I 37 and the through hole II 34, so that the outside air enters the gap 28 through the air inlet I 23, moves upward, and then passes through the gap left by the arc surface of the slider 51, and finally is discharged from the exhaust hole 29. The slider 51 blocks the air inlet II 27 to prevent a large amount of internal heat from being lost.

[0043] When the wind is weak in winter, when the slider 51 moves slightly upward or does not move upward at all, heat is dissipated in accordance with the above-mentioned summer heat dissipation method to keep the internal temperature of the inner box 25 constant.

[0044] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other forms of assembly without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-restrictive, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations within the meaning and range of equivalents of the claims be included in the invention.
