Description

Technical Field

[0001] The invention relates to the technical field of multifunctional rod bodies, and in particular to an electrical appliance door structure and a rod body structure. Background Art

[0002] Hollow poles such as lamp poles and communication poles are common outdoor equipment structures. They realize different functions such as lighting, communication, and smart device carrying through built-in electrical components such as lines and equipment. In order to facilitate the installation and maintenance of various electrical components, the hollow pole body needs to be provided with a door panel structure with opening and closing functions. The electrical components in the existing hollow pole body are generally set at the top of the pole body, which is located at a higher position. The control part of the electrical component is set at a lower position in the pole body and is connected by wires laid from top to bottom. The door panel structure is generally set within the height range of the human body to facilitate maintenance personnel to repair the control part of the electrical components above at the door panel structure and reduce the risk of climbing.

[0003] However, it was found during use that since the existing door panel has a simple structure and is generally connected to the hollow rod body by connecting parts such as bolts or screws, the connecting parts are not only easily loosened by vibration but also easily damaged by human beings. They are also easily lost after being removed by maintenance personnel during maintenance, resulting in poor protection of the door panel structure, requiring increased inspection frequency and reservation of accessories, and high subsequent maintenance costs, which affects the normal use of electrical components built into the hollow rod body. At the same time, the cables laid from top to bottom in the hollow rod body are generally freely suspended under the action of gravity. During use, water enters the top of the hollow rod body and flows along the cables to the control part, causing damage to the control part and shortening the service life of the electrical components. In addition, since the cable itself is heavy, the connection position with the electrical components is prone to loosening, which is also easy to cause This may cause damage to electrical components. During installation and maintenance, if the wires are disturbed under the hollow pole body, the wires are likely to fall and need to be repaired at a height, which increases the installation cost and maintenance cost of the cables in the hollow pole body, and increases the risk of climbing for maintenance and repair of electrical components in the hollow pole body. In addition, with the passage of time, the probability of installing additional equipment on an existing hollow pole body increases. For example, when adding smart equipment to a lighting pole, since there is no installation location for smart equipment on the hollow pole body, the existing solution is to replace the entire hollow pole body or re-drill holes in the hollow pole body. However, the cost of replacing the entire hollow pole body is extremely high, and re-drilling holes in the hollow pole body will affect the anti-corrosion layer on the surface of the hollow pole body and the overall waterproofness of the pole body, resulting in a shortened service life of the hollow pole body. Summary of the invention

[0004] The purpose of the present invention is to provide an electrical door structure and a rod body structure to address the technical problems of high maintenance and repair costs, short service life and difficulty in secondary installation of existing hollow rod bodies.

[0005] In order to achieve the above object, the technical solution adopted by the present invention is:

[0006] The electrical door structure includes a door frame and a door panel. One side of the door panel is movably connected to the door frame around the periphery, and a non-detachable connection device is provided on the other side. The non-detachable connection device includes a screw, a rotating block, a wing plate and a limit block. The non-detachable connection device can cooperate with the door frame to limit the position, and an expansion equipment limit mounting plate is provided on the inner circle of the door frame.

[0007] In the appliance door structure of the present invention, the door frame is a separately prepared metal structural member, which is used to be welded and connected to the corresponding door opening to achieve the position fixation of the appliance door structure; the movable connection is used to maintain the relative movement between the door panel and the door frame in the connected state, including rotational connection, plug-in connection, etc.; the captive connection device is used for the cooperative connection between the door panel and the door frame, when the captive connection device is connected to the door frame, the door panel is in a closed state, and when the captive connection device is disconnected from the door frame, the door panel is in an openable or open state; the extension equipment limit mounting plate is used to connect with the extension equipment through the holes reserved on the mounting plate after the door panel is removed, thereby providing convenience for secondary installation.

[0008] The appliance door structure of the present invention, by providing a door frame, has an overall high strength and is not easy to be damaged, which is beneficial to increasing the service life of the appliance door structure. At the same time, by providing a non-loose connection device, the appliance door structure has no loose parts after opening, thereby reducing the probability of loss of parts and reducing the cost of use and maintenance. At the same time, by reserving an expansion device limit installation plate in the door frame, the appliance door structure can be used as the installation position of the expansion device for later use, avoiding drilling and installation of the expansion device during the later use of the appliance door, providing convenience for secondary installation, and the expansion device limit installation plate can also further increase the overall strength of the appliance door structure.

[0009] As a preferred embodiment of the present invention, the non-loose connection device includes a screw, a rotating block and a limiting block, wherein the limiting block is arranged on the back of the door panel, the screw is passed through the door panel, the rotating block is limitedly rotated on the screw, a door-shaped structural member is arranged on the inner ring of the door frame to form a through hole, the door panel is provided with an extension section adapted to the through hole, the extension section is connected to the limiting member after passing through the through hole, and a grounding indicator is arranged on the door-shaped structural member. The limited rotation is to limit the rotating block to be able to rotate only within the range of the screw; the door-shaped structural member includes a vertical plate arranged on the inner side of the door frame and a horizontal plate used to connect the vertical plate, the horizontal plate and at least two of the vertical plates are detachably connected to form the door-shaped structural member; the extension section is a plate-shaped structure or a rod structure integrally formed with the door panel, one end or one side of the extension section after passing through the through hole is connected to the limiting member, so as to realize the movable connection between the door panel and the door frame.

[0010] As a preferred solution of the present invention, a box is provided on the back of the door panel, the door panel is provided with a plurality of first ventilation holes connected to the box, a plurality of second ventilation holes are provided on a side of the box near the top edge of the door panel, and a filter element is provided in the box to form a ventilation and dust filtering structure. The airflow outside the door panel enters the box from the first ventilation hole and then outputs from the second ventilation hole on the top of the box, so that the airflow passes through the airflow channel with bends and turns, reducing dust, moisture, etc. in the airflow after passing through the electrical door structure. The filter element is selected according to the actual application situation, and can be a structural member made of steel wool, asbestos, etc., to improve the thermal insulation and fire-retardant effects of the electrical door structure while achieving the ventilation and dust filtering effects.

[0011] The rod body structure comprises a rod body, on which at least one electrical appliance door structure as described above is arranged.

[0012] The rod body structure of the present invention, by arranging the above-mentioned electrical appliance door structure on the rod body, the electrical appliance door structure itself is not easy to be damaged and has a long service life, which is beneficial to extending the service life of the rod body and reducing the maintenance cost of the rod body. At the same time, the electrical appliance door structure provides an installation position for the installation of subsequent expansion equipment, and provides great convenience for the secondary installation of the existing rod body without affecting the overall structure of the rod body, forming a multifunctional rod body, and avoiding damage to the rod body by secondary installation, thereby extending the service life of the rod body. When installing the expansion equipment, it is only necessary to remove the door panel as a whole and install the expansion equipment on the expansion equipment limit installation plate of the electrical appliance door structure, thereby shortening the installation period and installation cost of the expansion equipment and expanding the functionality of the rod body.

[0013] As a preferred solution of the present invention, an electric control box is arranged in the rod body corresponding to the electrical door structure, and the electric control box includes a top plate and an installation box for installing electric control elements, the top plate is fixedly connected to the inner wall of the rod body, the installation box is arranged at the bottom of the top plate, and the side of the installation box facing the door plate is arranged as an open structure, and a plurality of cables are connected to the electric control elements after being wrapped around the back and bottom of the installation box to form a drip ring. The electric control box is suspended in the rod body through the lateral support of the top plate and the hanging installation of the installation box. The blocking effect of the top plate on the top of the electric control box improves the overall waterproof effect of the installation box, ensures the normal use of the electric control elements, and reduces the maintenance and repair frequency. At the same time, the cable installation structure in which the cable wraps around the installation box to form a drip ring makes the rainwater above the rod body along the cable drip from the bottom of the drip ring to avoid water accumulation from entering the installation box, further improving the overall waterproof effect of the electric control box.

[0014] As a preferred solution of the present invention, a waterproof structure mounting plate is provided at the edge of the top plate, and the waterproof structure mounting plate is provided with a hanging hole adapted to the mounting box or is connected with the mounting box by snapping. The waterproof structure mounting plate is formed by bending the edge of the top plate to further improve the shielding, water blocking and protection effect of the mounting box below. The mounting box is not easy to enter water due to the cooperation of the special bending structure of the top and the cable, so that it can be set as an open-mouth structure to facilitate the installation and maintenance of various electronic control components.

[0015] As a preferred solution of the present invention, a guide rail is longitudinally arranged on the outer wall of the rod body, a wire port cover can be detachably connected to the guide rail to form a wire arrangement space, a wire hole is arranged on the rod body to communicate with the wire arrangement space, a wire passing mechanism is arranged on the wire hole, and the electric control box is located below the wire passing hole. The cables are arranged from the outer wall of the rod body, which reduces the number of cables in the rod body and facilitates the longitudinal position limitation of the cables on the outer wall of the rod body. At the same time, it is convenient to open the wire port cover later and maintain and repair the cables outside the rod body, which overcomes the existing situation of installing and repairing cables inside the rod body, too small space, difficulty in fixing and limiting the cables in the longitudinal direction, and messy cable arrangement.

[0016] As a preferred embodiment of the present invention, the wire-passing mechanism includes a wire-clamping mechanism, which is adaptably connected to the wire-passing hole, and a plurality of wire-passing tubes are arranged on the wire-clamping mechanism, and the wire-passing tubes are elastic material structural members, and the wire-clamping mechanism is integrally formed with all the wire-passing tubes. After the wire-clamping mechanism is connected to the wire-passing hole, a setting plane is provided for all the wire-passing tubes, and the wire-passing hole has a sealing effect, thereby improving the sealing performance of the rod body. When in use, the cable passes through the wire-passing tube, and is affected by the elastic deformation of the wire-passing tube, and is constrained and stabilized, thereby preventing the cable from uncontrollable displacement along the longitudinal direction of the rod body, so that the wire-passing mechanism not only has the function of a wire-passing hole, but also has the function of limiting the position of the cable.

[0017] As a preferred solution of the present invention, all the wire tubes are inclined toward the inner bottom of the rod body, and one end of the wire tube away from the wire hole is set as a closed end. The inner diameter of the wire tube gradually decreases along the wire hole to the closed end, and the closed end is cut off and removed when the wire is threaded. The inclined setting state of the wire tube makes the wire tube have a certain guiding effect. On the one hand, it is adapted to the cable arrangement direction, so that the cable is arranged obliquely downward after passing through the wire tube, avoiding large angle bending, ensuring the safe arrangement and installation of the cable and long-term use. On the other hand, it is adapted to the direction of water flow such as rainwater entering the rod body, avoiding water accumulation at the wire hole. At the same time, the conical tube structure of the wire tube enables the wire tube to be adapted to the fixing of cables of different models, and has a wide range of adaptability. In addition, the closed end is reserved during the preparation of the wire tube, and the structure setting for cutting on site enables the wire tube to cut the length according to the actual situation of the cable on site, thereby improving the adaptability of the wire passing mechanism.

[0018] As a preferred solution of the present invention, a wire clamping ring is inserted into the wire hole, the wire clamping mechanism is clamped and connected with the wire clamping ring, the wire clamping mechanism is provided with sealing ridges on both axial sides of the wire clamping ring to form an annular sealing groove ring, and the wire clamping mechanism, the wire passing tube and the sealing ridges are integrally formed parts of elastic materials. The provision of the wire clamping ring increases the extension length of the wire hole, avoids the cable from being scratched and peeled at the wire hole, ensures the service life of the cable, and avoids the increase in maintenance and repair costs caused by cable damage. At the same time, it is also conducive to improving the waterproof effect at the wire hole, and cooperates with the wire clamping mechanism to form two sealing ridges located inside and outside the rod body, which avoids water ingress into the rod body to the greatest extent, ensures the service life of the electrical components in the rod body, and reduces the later maintenance and repair costs of the rod body.

[0019] As a preferred solution of the present invention, the cable arrangement space is provided with a plurality of cable fixing rings, which are symmetrically distributed on both sides of the wire hole, and the cable fixing rings are provided with fixing parts. The cable fixing rings and fixing parts are provided to fix the cables in the horizontal direction, and the cable passing tube is used to fix the cables in the vertical direction, so as to ensure the stability of the position of the cables in the cable arrangement space to the greatest extent, and avoid the increase of maintenance and repair costs caused by the cables falling off.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0021] 1. The electrical appliance door structure of the present invention has a door frame, so that the overall strength of the electrical appliance door structure is high and not easily damaged, which is beneficial to prolonging the service life of the electrical appliance door structure;

[0022] 2.

[0023] 3. The electrical appliance door structure of the present invention can be used as the installation position of the expansion device in the later use by reserving the expansion device limit installation plate in the door frame, so as to avoid drilling holes to install the expansion device in the later use of the electrical appliance door, and provide convenience for secondary installation. The expansion device limit installation plate can also further increase the overall strength of the electrical appliance door structure;

[0050] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0051] Example 1

The door panel 2 is movably connected to the door frame 1 on one side around the circumference, and a non-detachable connecting device 22 is provided on the other side. The non-detachable connecting device 22 can cooperate with the door frame 1 in a limiting manner. The inner circle of the door frame 1 is provided with an expansion equipment limiting mounting plate 11.

[0053] The appliance door structure of this embodiment is characterized in that the door frame 1 is a separately prepared quadrilateral metal frame structural member, which is welded and connected to the corresponding door opening when in use to form a reinforced appliance door structure; the door panel 2 is a plate-type metal structural member adapted to the inner cavity structure of the door frame 1, and can be embedded in the door frame 1 to achieve the closure of the appliance door structure; the expansion device limit mounting plate 11 is a plate-like structural member welded in the door frame 1, parallel to the door panel 2 in the closed state, and installation holes are reserved on the expansion device limit mounting plate 11 according to actual conditions.

[0054] The appliance door structure of the present embodiment has a non-detachable connecting device 22 provided on the inner side of the door panel 2 near the top, an extension section 24 of a plate-like structure is welded to one side of the bottom of the door panel 2, a through hole is provided in the door frame 1 at a position corresponding to the bottom of the door panel 2, the non-detachable connecting device 22 comprises a screw rod 221, a rotating block 222 and a limit block 224, the screw rod 221 is passed through the door panel 2, the rotating block 222 rotates within the range of the screw rod 221, the limit block 224 is a metal plate structure, welded at a position close to the screw rod 221, and is used to block the wing plate 223 provided on the rotating block 222, thereby limiting the rotation range of the rotating block 222.

[0055] Specifically, Figure 1 As shown, the preferred limit block 224 is a metal plate bending part having two outer surfaces set at an angle, which can specifically limit the rotation range of the rotating block 222 through the angle between the two outer surfaces, so as to achieve control of the tightness of the connection between the door panel 2 and the door frame 1 when the screw 221 is rotated clockwise and counterclockwise.

When the door panel 2 is installed, after the extension section 24 is passed through the through hole 12, a limit piece is set on the extension section 24 to prevent the extension section 24 from being disconnected from the through hole 12, thereby realizing the movable connection between the door panel 2 and the door frame 1.

[0057] Specifically, Figure 3 As shown, according to actual conditions, a stop plate 13 is provided on the door frame 1 at a position corresponding to the non-detachable connection device 22 to cooperate with the rotating block 222 in a limiting manner.

[0063] Specifically, a filter element can be set in the box according to actual conditions. The filter element material is selected according to actual application conditions. It can be a structural member made of steel wool, asbestos and other materials. While achieving ventilation and dust filtering effects, it also improves the thermal insulation and fire-retardant effects of the appliance door structure.

[0064] Example 3

[0065] like Figure 7-Figure 8 As shown, the rod body structure includes a hollow rod body 3, and at least one electrical appliance door structure as described above is arranged on the rod body 3.

[0066] The rod body structure of the present embodiment is provided with the above-mentioned electrical door structure on the hollow rod body 3. The electrical door structure itself is not easy to be damaged and has a long service life, which is beneficial to prolonging the service life of the rod body 3 and reducing the maintenance cost of the rod body. At the same time, the electrical door structure provides an installation position for the installation of later expansion equipment. Without affecting the overall structure of the rod body, it provides great convenience for the secondary installation of the existing rod body and avoids the influence of the secondary installation on the service life of the rod body 3. When installing the expansion equipment, it is only necessary to remove the door panel 2 as a whole and install the expansion equipment on the expansion equipment limit installation plate 11 of the electrical door structure, thereby shortening the installation period and installation cost of the expansion equipment. At the same time, after the door panel 2 of the electrical door structure is closed, the external airflow passes through the first ventilation hole 21, the box body 23, and the second ventilation hole 231, and enters the rod body 3 of the towering structural member, forming a chimney effect, realizing ventilation and cooling of the equipment in the rod body, and providing support for the normal use of the rod body in high temperature and harsh outdoor environment.

At the same time, Fig.13As shown, when the cables are connected, after the cables are wrapped around the back and bottom of the installation box 5, they are connected to the electronic control components 6 in the installation box 5 from bottom to top, so that each cable forms a drip ring 7, so that rainwater entering the upper part of the rod body 3 along the cable drips from the bottom of the drip ring 7, avoiding accumulated water from entering the installation box 5, thereby further improving the overall waterproof effect of the installation box 5.

[0071] Specifically, the top plate 41 and the waterproof structure mounting plate 411 can be adjusted in shape, inclination, and size according to actual conditions to improve the waterproof effect of the mounting box 5 .

The wire port cover 82 is shielded on the guide rail 81 and is detachably connected to the rod body 3 to form a wire arrangement space 8 on the outer wall of the rod body 3.

[0076] Specifically, Figure 19-21 As shown, the cross section of the rod body 3 can be nearly circular or polygonal, and can also be adjusted according to actual conditions. According to actual conditions, the guide rail 81 and the wire passing port 82 can be respectively set on one side or multiple sides of the rod body 3.

[0077] Preferably, Fig.17As shown, the wire hole 31 is located at the end position of the wire arrangement space 8, and the electric control box 4 is located in the rod body below the wire hole 31. After the cable passes through the wire arrangement space 8 from the equipment above the rod body 3, it enters the rod body 3 from the wire hole 31, and then passes around the back and bottom of the electric control box 4, and then penetrates from the bottom of the electric control box 4, and is connected with the electric control element 6 in the electric control box 4 to form a drip ring 7.

[0078] In the rod structure of the present embodiment, the cables are arranged from the outer wall of the rod body 3. Compared with the conventional rod structure, the length of each cable passing through the rod body 3 is reduced, and the threading process in a narrow space is changed to laying without space restriction on the outer wall of the rod body 3, which is convenient for limiting the position of the cables on the outer wall of the rod body 3 in the longitudinal direction, greatly reducing the difficulty and engineering workload of laying cables in the rod structure. At the same time, each cable forms a drip ring 7, and the moisture intruding from the upper part of the rod structure is discharged from the outer wall of the rod body 3 along the cable. Even if it penetrates into the interior of the rod body 3 from the wire hole 31, it can be collected at the bottom of the drip ring 7 without affecting the use of the electric control box 4, thereby improving the waterproof effect of the electric control box 4. At the same time, it is convenient to open the wire port cover 82 at a later time and maintain and repair the cables outside the rod body 3, overcoming the existing situation of cable installation and maintenance in the rod body 3, too small space, difficulty in fixing and limiting the cables in the longitudinal direction, and scattered cable arrangement.

[0079] Example 6

[0080] like Figure 14-Figure 21 As shown, the rod structure of this embodiment is the same as that of embodiment 4, with the difference that: the wire passing mechanism 9 includes a wire clamping mechanism 91, and the wire clamping mechanism 91 is adaptably connected to the wire passing hole 31, and a plurality of wire passing tubes 92 are arranged on the wire clamping mechanism 91, and the wire passing tubes 92 are elastic material structural parts, and the wire clamping mechanism 91 and all the wire passing tubes 92 are integrally formed.

[0081] The rod body structure of this embodiment, the wire clamping mechanism 91 is a silicone material structural member, which can be connected to the wire passing hole 31 through elastic deformation or shape matching. A plurality of wire passing tubes 92 are integrally formed on the wire clamping mechanism 91, and at least one cable can pass through each wire passing tube 92. In this embodiment, the wire clamping mechanism 91 provides a setting plane for all wire passing tubes 92, and has a sealing effect on the wire passing hole 31, thereby improving the sealing performance of the rod body 3. When in use, the cable passes through the wire passing tube 92, is affected by the elastic deformation of the wire passing tube 92, is constrained and stabilized, and avoids uncontrollable displacement of the cable along the longitudinal direction of the rod body 3, so that the wire passing mechanism 9 not only has the function of the wire passing hole 31, but also has the function of limiting the position of the cable.

[0082] Preferably, all the wire passing tubes 92 are inclined toward the inner bottom of the rod body 3, and one end of the wire passing tube 92 away from the wire passing hole 31 is set as a closed end 921. The inner diameter of the wire passing tube 92 gradually decreases along the wire passing hole 31 to the closed end 921, and the closed end 921 is cut off and removed by the wire passing tube 92 when threading.

[0083] Specifically, the inclined setting state of the wire tube 92 makes the wire tube 92 have a certain guiding effect. On the one hand, it guides the cable arrangement direction so that the cables are arranged obliquely downward after passing through the wire tube 92, avoiding large-angle bending, thereby ensuring the safe arrangement, installation and long-term use of the cables. On the other hand, it guides the direction of water flow such as rainwater entering the rod body 3, avoiding water accumulation in the wire hole 31. At the same time, the conical tube structure setting of the wire tube 92 not only further improves the guiding effect, but also enables the wire tube 92 to be adapted to the binding and fixation of cables of different types, with a wider range of adaptability. In addition, the closed end 921 is reserved for the wire tube 92 during preparation, and the structural setting and use method for intercepting on site enable the wire tube 92 to be cut in length according to the actual situation of the cable on site, thereby improving the use range of the wire passing mechanism 9.

[0084] Preferably, a wire clamping ring 32 is inserted into the wire hole 31, and the wire clamping mechanism 91 is clamped and connected with the wire clamping ring 32. The wire clamping mechanism 91 is provided with sealing ridges 93 on both axial sides of the wire clamping ring 32 to form an annular sealing groove ring. The wire clamping mechanism 91, the wire tube 92 and the sealing ridges 93 are integrally formed parts of elastic material. In this embodiment, the wire clamping ring 32 is a metal ring welded in the wire hole 31. The provision of the wire clamping ring 32 increases the length of the wire hole 31, increases the contact area between the cable and the wire hole 31, avoids the cable from being scratched and peeled at the wire hole 31, ensures the service life of the cable, and avoids the increase of maintenance and repair costs caused by cable damage.

[0085] Preferably, in this embodiment, the shape of the wire clamping mechanism 91 is adapted to the wire clamping ring 32, sealing ridges 93 are provided at both axial ends of the wire clamping mechanism 91, and an annular sealing groove ring adapted to the wire clamping ring 32 is formed on the outer wall of the wire clamping mechanism 91. The wire clamping mechanism 91 is arranged in the wire clamping ring 32, and the sealing ridges 93 at both ends are used to limit and seal, so as to further improve the waterproof effect of the wire hole 31, avoid water ingress into the rod body 3 to the greatest extent, ensure the service life of the electrical components in the rod body 3, and reduce the later maintenance and repair costs of the rod body 3.

[0086] Example 7

[0087] like Figure 14-18As shown, the rod structure of this embodiment is the same as that of embodiment 6, except that: the wiring space 8 is provided with a plurality of cable fixing rings 10, and the cable fixing rings 10 are symmetrically distributed on both sides of the wire hole 31, and the cable fixing rings 10 are provided with fixing parts 20.

[0088] The rod body structure of this embodiment is based on embodiment 6, and cable fixing rings 10 are respectively provided on the left and right sides of one side of the wire hole 31 close to the outer wall of the rod body 3. The cable fixing ring 10 is used to pass the fixing member 20, and the cable is stably connected to the rod body 3 through the fixing member 20, so as to achieve the fixation of the cable in the lateral direction, and cooperate with the wire tube 92 to fix the cable in the vertical direction, so as to ensure the stability of the position of the cable in the wiring space to the greatest extent, and avoid the increase of maintenance and repair costs caused by the cable falling off.

[0089] Specifically, the fixing member 20 is preferably a cable tie, and the cable fixing ring 10 is preferably a metal ring washer.
