Detailed implementation manners

[0032] The following combines the drawings and embodiments to further describe the detailed implementation manners of the present utility model. The following embodiments are only used to more clearly illustrate the technical solutions of the present utility model, and cannot be used to limit the protection scope of the present utility model.

[0033] As Figures 1-11 shown, the ventilation and heat dissipation device of the communication integrated box body of the present utility model includes:

[0034] A ventilation shell, which is used to be installed at the ventilation opening of the communication integrated box body and is in fit connection with the communication integrated box body. The ventilation shell includes a front cover 1 and a rear cover 2 that are rotatably connected to each other. The front cover 1 and the rear cover 2 are connected with a locking component for locking the two to enclose a ventilation cavity. The front cover 1 and the rear cover 2 are respectively provided with a front vent 11 and a rear vent 21 that are both communicated with the ventilation cavity;

[0035] A filter, which is arranged in the ventilation cavity;

[0036] A heat dissipation component 4, which is arranged on the side of the rear cover 2 away from the front cover 1. The heat dissipation component 4 includes a heat dissipation motor 43 and a heat dissipation fan 44. The heat dissipation fans 44 are annularly arrayed with the axis line of the output shaft of the heat dissipation motor 43 as the center line.

[0037] This device is mainly used to be installed at the ventilation opening of the communication integrated box body. During installation, the side of the rear cover 2 of the ventilation shell away from the front cover 1 is in fit with the outer side wall of the communication integrated box body, and the heat dissipation component 4 enters the interior of the communication integrated box body through the ventilation opening of the communication integrated box body; when the communication integrated box is running, the heat dissipation motor 43 in the heat dissipation component 4 starts, driving the heat dissipation fan 44 to rotate, generating an air flow, guiding the air inside the communication integrated box body and the external air to exchange and flow, so as to realize the ventilation and heat dissipation inside the communication integrated box body, ensure the safe and stable operation of the internal facilities. During the ventilation and heat exchange process, when the air flows between the front vent 11, the ventilation cavity and the rear vent 21, the filter can filter impurities such as dust particles and water vapor in the air, thereby ensuring the cleanliness of the internal environment of the communication integrated box body and avoiding affecting the ventilation and heat dissipation effect.

[0038] Compared with the prior art, in the present utility model, the ventilation housing mainly consists of a front cover 1 and a rear cover 2. The front cover 1 and the rear cover 2 are rotatably connected, and a locking assembly is connected between them. Through the locking assembly, the front cover 1 and the rear cover 2 can be locked and connected, so that the front cover 1 and the rear cover 2 enclose a ventilation cavity, that is, the inner cavity of the ventilation housing. Therefore, there is no need for a structure-assisted unlocking part, and the number of components of the ventilation housing is correspondingly reduced, thus simplifying the structure and being beneficial to reducing the production cost of the device.

[0039] The specific structure of the front cover 1 of the present utility model is as Figure 6 and Figure 7 shown. The front cover 1 includes a square frame 14. On the side of the frame 14 facing away from the rear cover 2, there is a square outer frame 15. The circumferential outer edge of the outer frame 15 is flush with the circumferential outer edge of the frame 14. The length of the circumferential inner wall of the outer frame 15 is less than the length of the circumferential inner wall of the frame 14. On the side of the outer frame 15 away from the frame 14, there is a louver 16. The louver 16 includes strip-shaped window plates 161 distributed at intervals. The two ends of the window plate 161 are flush with two opposite side walls of the outer frame 15. After the ventilation and heat dissipation device is installed, the window plates 161 extend in the horizontal direction and are distributed at intervals in the vertical direction. The top surface of the window plate 161 is inclined downward, which is convenient for rainwater to fall on the outside of the communication integrated box along the inclined top surface of the window plate 161 when it rains outdoors, avoiding entering the ventilation cavity. Inside the frame 14, there are limiting strips 17 extending in the vertical direction and distributed at intervals in the horizontal direction. The two ends of the limiting strips 17 are respectively fixedly connected to the inner bottom wall and the inner top wall of the frame 14; the louver 16, the limiting strips 17 and the outer frame 15 enclose the front ventilation opening 11 of the front cover 1.

[0040] The specific structure of the rear cover 2 of the present utility model is as Figure 8 and Figure 9 shown. The rear cover 2 includes a square inner frame 26. At one end of the inner frame 26 adjacent to the front cover 1, there is a second flanging 27. When the front cover 1 and the rear cover 2 are locked and connected, the circumferential outer edge of the second flanging 27 is hermetically connected to the circumferential inner wall of the frame 14 and the second flanging 27 abuts against the side of the limiting strip 17 away from the louver 16 to ensure the stable connection of the front cover 1 and the rear cover 2; at one end of the inner frame 26 away from the front cover 1, a ventilation wire mesh frame 28 is fixed. The mesh holes on the ventilation wire mesh frame 28 form the rear ventilation opening 21 of the rear cover 2.

[0041] In order to facilitate the fixed connection between the ventilation housing and the communication integrated box, at the four corners of the second flanging 27, second nuts 29 are also fixedly arranged. When the device is installed, by drilling holes in the side wall of the communication integrated box and drilling holes from the inside of the communication integrated box, and screwing screws into the holes to be threadedly connected with the second nuts 29, the fixed connection of the ventilation and heat dissipation device on the communication integrated box can be completed.

[0042] A further improvement is that the locking assembly includes a clamping protrusion 22 and a clamping hook 12 which are clamped and matched with each other. Among the clamping protrusion 22 and the clamping hook 12, one is arranged on the front cover 1 and the other is arranged on the rear cover 2. Among the front cover 1 and the rear cover 2, one is provided with a slot 13 and the other is provided with an insertion strip 23. The front cover 1 and the rear cover 2 are rotatably connected through the slot 13 and the insertion strip 23. The relative rotation axis of the front cover 1 and the rear cover 2 and the locking assembly are respectively arranged on opposite sides of the ventilation shell.

[0043] Specifically, as Figures 5-9 shown, among them, the slot 13 is arranged on the inner bottom wall of the frame 14. The slot 13 extends along the length direction parallel to the window pane 161 and is spaced apart in two along its own length direction. There are two insertion strips 23, corresponding to the two slots 13 one by one. The insertion strips 23 are spaced apart along their own length direction and are integrally formed at the bottom of the second flange 27. The length of the insertion strip 23 is slightly less than the length of the slot 13, the width of the insertion strip 23 is slightly less than the width of the slot 13, and the thickness of the insertion strip 23 is slightly less than the depth of the slot 13. In this way, it is convenient for the insertion strip 23 to be inserted into the slot 13. Through the insertion strip 23 and the slot 13, it is convenient for the rear cover 2 to rotate with its bottom side wall as the axis line. The width of the second flange 27 of the rear cover 2 is the same as the inner width of the frame 14, ensuring that before the locking assembly locks the front cover 1 and the rear cover 2, the front cover 1 and the rear cover 2 can have a stable relative rotational connection.

[0044] There are four clamping hooks 12 and four clamping protrusions 22, which are spaced apart along the length direction parallel to the window pane 161 and are grouped in pairs. Specifically, two notches 141 spaced apart along the length direction parallel to the window pane 161 are arranged on the surface of the frame 14 adjacent to the rear cover 2 at the top. Two clamping hooks 12 are integrally formed on the inner sides of the two notches 141. The clamping hooks 12 are L-shaped. The clamping hook 12 includes a connecting arm 121 and a clamping arm 122. The clamping arm 122 is integrally connected to the inner bottom wall of the notch 141 through the connecting arm 121, so that the clamping arm 122, the connecting arm 121 and the notch 141 form a clamping groove. The clamping protrusion 22 is integrally formed on the top of the second flange 27. The clamping protrusion 22 is a right-angled triangular prism. One right-angled surface coincides with the plane of the side wall of the top of the second flange 27, and this right-angled surface is the connecting surface. The other right-angled surface coincides with the plane of the surface of the second flange 27 away from the front cover 1, and this right-angled surface is the clamping surface. In this way, when the front cover 1 and the rear cover 2 are rotatably connected and not locked, the inclined surface of the right-angled triangular prism-shaped clamping protrusion 22 faces the clamping arm 122 of the clamping hook 12, which is convenient for the clamping protrusion 22 to be clamped into the clamping groove.

[0045] To further ensure the fixed connection effect between the front cover 1 and the rear cover 2 after snap connection, the snap protrusion 22 is clamped between two opposite side walls of the snap groove. Specifically, the width dimension of the right-angle surface is the same as the distance between the snap arm 122 and the inner bottom wall of the notch 141, so that the side of the connection surface away from the snap surface abuts against the inner bottom wall of the notch 141, and the snap surface fits against the surface of the snap arm 122 facing the inner bottom wall of the notch 141. In this way, the locking connection effect between the front cover 1 and the rear cover 2 is ensured, preventing loosening.

[0046] A further improvement is that an elastic sealing ring 24 is provided on the surface of the ventilation shell that fits with the communication integrated box body, and the sealing ring 24 is used to surround the outside of the ventilation opening.

[0047] Specifically, the sealing ring 24 is a rubber ring and is fixed to the surface of the second flanging 27 away from the front cover 1. By providing the elastic sealing ring 24, after the ventilation and heat dissipation device is safely completed, the sealing ring 24 is clamped between the outer side wall of the communication integrated box body and the second flanging 27, filling the gap between the second flanging 27 and the communication integrated box body, thereby preventing water vapor and dust from entering the ventilation opening and ensuring the sealing effect while realizing safe ventilation and heat dissipation inside the communication integrated box body.

[0048] A further improvement is that the filter is a filter cotton 3.

[0049] Through the filter cotton 3, impurities such as water vapor and dust particles in the external air can be filtered, ensuring the dryness and cleanliness inside the communication integrated box body, which is beneficial to the safety of ventilation and heat dissipation.

[0050] A further improvement is that the heat dissipation component 4 further includes a heat dissipation cylinder 41 and bolts 42. The heat dissipation motor 43 and the heat dissipation fan 44 are both arranged inside the heat dissipation cylinder 41, and the heat dissipation cylinder 41 is connected to the ventilation shell through the bolts 42; at least two groups of first nuts 25 for threaded connection with the bolts 42 are provided on the ventilation shell, and the connection lines of the first nuts 25 in each group of first nuts 25 enclose an installation area, and the installation areas corresponding to each group of first nuts 25 have different sizes.

[0051] The specific structure of the heat dissipation component 4 is as Figure 10 and Figure 11As shown in the figure, the heat dissipation cylinder 41 is a cylinder, and square first flanges 411 are integrally connected to both ends. The housing of the heat dissipation motor 43 is fixedly connected to the circumferential inner wall of the heat dissipation cylinder 41, and the output shaft faces the ventilation housing and is fixedly connected to the heat dissipation fan 44. A dust-proof net 45 is further provided at one end of the heat dissipation cylinder 41 away from the ventilation housing to prevent dust particles and impurities from entering the heat dissipation cylinder 41 and ensure the safe operation of the heat dissipation motor 43. Bolts 42 are respectively passed through the four corners of the first flange 411, and the bolts 42 are passed through the end of the dust-proof net 45; a connection component is fixed on the ventilation network frame 28, and the connection component includes first nuts 25 that are threadedly connected to the four bolts 42 one by one. Through the connection of the bolts 42 and the first nuts 25, the dust-proof net 45 and the heat dissipation cylinder 41 are fixed on the ventilation network frame 28.

[0052] Three connection components are provided on the ventilation network frame 28. Each of the three connection components includes four first nuts 25. The connection lines of the four first nuts 25 form a square installation area. The centers of the installation areas corresponding to the three connection components are the same, and the side length directions are parallel. In this way, three installation areas are formed on the ventilation network frame 28, and the sizes of the three installation areas are different. Therefore, according to the size of the ventilation opening of the communication integrated box, the heat dissipation component 4 of the corresponding size type can be selected, so as to expand the applicable range of the device, avoid the installation failure caused by the too small size of the ventilation opening of the communication integrated box and the inability to pass through the heat dissipation cylinder 41, and avoid the too large size of the ventilation opening, resulting in the relatively small size of the heat dissipation cylinder 41 and affecting the ventilation and heat dissipation effect.

[0053] The above is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and retouches can still be made, and these improvements and retouches should also be regarded as the protection scope of the present invention.
