Description
Technical Field
[0001] The utility model relates to the technical field of electric power operation equipment, in particular to a vehicle-mounted foldable rain and snow-proof cable splitter box. Background Art
[0002] Due to its good cross-country performance and the ability to adapt to outdoor open-air operations all-weather, electric power operation vehicles have been widely used in occasions such as electric power emergency repair, mobile communication, large-scale conferences, engineering emergency rescue, and military activities.
[0003] As an important device on the electric power operation vehicle, the vehicle-mounted cable splitter box plays a role in quickly restoring power supply when the cable is led out from the vehicle-mounted splitter box to the electrical load during the emergency power supply guarantee process. At the same time, the cable splitter box is also an important device for splitting, branching, connecting, and converting circuits of the cable line.
[0004] There are generally two common types of vehicle-mounted splitter boxes. One type is that the splitter box has an upward-opening door or a flat-opening door, and a cable inlet hole is opened at the bottom, adopting the bottom-inlet method. The other type is that the splitter box has an upward-opening door or a flat-opening door, adopting the door-inlet method. For the first type of splitter box using the bottom-inlet method for the box body, due to a certain bending radius of the external cable, the front and rear thickness dimensions of the cable splitter box need to be larger, so the splitter box will occupy more carriage space, thus reducing the utilization rate of the carriage space; although the second type of splitter box occupies less space in the carriage, the door cannot be closed for operation after the cable is connected, and there is a risk of accidental contact by uninformed personnel. Secondly, in case of rain and snow weather, rain and snow falling on the joint cable will reduce its service life, and there are also potential safety hazards.
[0005] Therefore, there is an urgent need for a vehicle-mounted foldable rain and snow-proof cable splitter box to solve the above technical problems. Content of the Utility Model
[0006] The purpose of the utility model is to overcome the problems in the background art and provide a vehicle-mounted foldable rain and snow-proof cable splitter box. When in use, the thickness of the splitter box can be increased, and when not in use, it can be folded and compressed. Therefore, it not only occupies less carriage space, but also can prevent accidental contact, prevent rain and snow, and ensure the connection safety of the cable during the operation process.
[0007] In order to achieve the above utility model purpose, the technical solution adopted by the utility model is specifically as follows: a vehicle-mounted foldable rain and snow-proof cable splitter box, including a box body, an inlet hole is provided at the rear side of the box body, and it is characterized in that an upward-opening door panel is connected to the upper side of the front end of the box body through an upper hinge, folding doors are respectively arranged on the left and right sides of the front end of the box body, and a limiter is arranged on one of the folding doors; a water flow edge is arranged at the front end of the box body, and the water flow edge is located above the upper hinge.
[0008] When the front end of the tap box is closed, the folding door with a limiter can press another folding door, and at the same time, the upper turning door panel can be locked by the upward turning of the limiter.
[0009] When the front end of the tap box is opened, the two folding doors on both sides can be unfolded together, increasing the front-to-back thickness of the tap box. At the same time, a space is formed that is completely enclosed on all sides except for the bottom inlet.
[0010] Further, the folding door includes a side hinge connected to the front side wall of the box body. The other side of the side hinge is connected with a right-angled trapezoidal door panel, and a rectangular door panel is hinged to the side of the right-angled trapezoidal door panel away from the side hinge.
[0011] Further, the horizontal length of the right-angled trapezoidal door panel should be at least greater than half of the width of the box body, and the horizontal length of the rectangular door panel should be less than the horizontal length of the right-angled trapezoidal door panel.
[0012] Further, when the front end of the tap box is in the open state, magnetic attraction strips are respectively arranged on the sides of the two rectangular door panels close to each other.
[0013] Further, nylon drawstrings are arranged on the outer sides of the right-angled trapezoidal door panel and the rectangular door panel.
[0014] Further, the limiter adopts a 360-degree limiter, which can rotate 90 degrees and is arranged on the outer side of the right right-angled trapezoidal door panel or the left right-angled trapezoidal door.
[0015] Further, limit blocks are respectively arranged on both sides of the upper turning door panel, and the limit blocks are used to limit the outward expansion when the corresponding folding door is unfolded.
[0016] Further, a feed-out panel is arranged in the box body, an output socket is arranged on the feed-out panel, and the output socket is arranged at an acute angle with the ground, preferably at an angle of 30 degrees.
[0017] Further, the right-angled trapezoidal door and the rectangular door are connected by a hinge.
[0018] Further, the magnetic attraction strip is of a Z-shaped structure.
[0019] Compared with the prior art, the beneficial effects of the present utility model are:
[0020] 1. The front end of the tap box is provided with an upward-opening door panel and two folding doors. When the tap box is not in use, the upward-opening door panel and the two folding doors can be folded and compressed together, reducing the front-to-back thickness of the tap box. When the tap box needs to be operated, the two folding doors on both sides can be unfolded and, together with the upward-opening door panel, form an independent operating space protruding from the carriage, thus extending the front-to-back thickness of the tap box. Therefore, this protruding operating space makes it convenient for the staff to operate while minimizing the occupation of the interior space of the carriage, which is conducive to improving the utilization rate of the interior space of the carriage.
[0021] 2. After the front end of the tap box is opened and unfolded, a space is formed that is completely enclosed on all sides except for the bottom inlet. Therefore, it can prevent the misoperation of uninformed personnel and is conducive to improving the safety of the tap box. Secondly, when encountering rainy or snowy weather, the sealed space formed by the two folding doors and the upward-opening door panel at the top can block rain and snow from falling on the cable connectors, thereby increasing the service life of the cable connectors and eliminating potential safety hazards.
[0022] 3. When in the closed state, the upward-opening door panel and the two folding doors of the present utility model can be folded and compressed together and be flush with the carriage surface, which will not affect the normal driving of the vehicle. At the same time, the structure of the present utility model is simple, with low cost, easy to manufacture and process, and light in weight. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] To make the objectives, technical solutions and advantages of the present utility model more clear and understandable, the present utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. Of course, the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.
[0030] Embodiment: As Figures 1-4 shown, this embodiment provides a vehicle-mounted foldable rain and snow-proof cable distribution box, which is composed of a box body 1, a water flow edge 2, a feed-out panel 3, an output socket 4, an upper hinge 5, an upper flip door 6, a left rectangular door 7, a Z-shaped magnetic strip 8, a right rectangular door 9, a nylon pull rope 10, a hinge 11, a left right-angled trapezoidal door 12, a left hinge 13, a right right-angled trapezoidal door 14, a right hinge 15, a 360-degree limiter 16, a limit block 17, etc.
[0031] Among them, the left right-angled trapezoidal door 12, the left rectangular door 7 and the left hinge 13 form a left folding door, and the right right-angled trapezoidal door 14, the right rectangular door 9 and the right hinge 15 form a right folding door.
[0032] The box body 1 is welded by multiple bent plates, and an inlet hole is opened at the lower position of the back of the box body for the access of other power sources such as vehicle-mounted generator sets.
[0033] The feed-out panel 3 adopts a multi-folded form, so that the surface of the feed-out panel 3 where the output socket 4 is fixed forms a 30-degree angle with the ground plane. When an external cable is connected to the distribution box, the force at the coupling of the cable joint and the output socket 4 can be made smaller, and at the same time, it is more smooth for the operator to plug and unplug the cable, and more attention is paid to the ergonomics.
[0034] The output socket 4 can adopt models of different brands and is fixed on the feed-out panel 3 in a bolt-fixed form.
[0035] The upper flip door 6 is welded to one side of the upper hinge 5, and the other side of the upper hinge 5 is welded to the upper edge of the box body 1. The upper flip door 6 can be turned up and down around the upper hinge 5.
[0036] The left folding door is composed of a left right-angled trapezoidal door 12, a left rectangular door 7 and a left hinge 13. The short side of the left right-angled trapezoidal door 12 is fixed to one side of the left rectangular door 7 through a hinge 11. The long side of the left right-angled trapezoidal door 12 is welded to one side of the left hinge 13, and the other side of the left hinge 13 is welded to the left side of the box body 1. In this way, the left rectangular door 7 can rotate around the hinge 11, the left right-angled trapezoidal door 12 can rotate around the left hinge 13, and at the same time, the left rectangular door 7 and the left right-angled trapezoidal door 12 can also be folded together. The Z-shaped magnetic strip 8 is glued to the other side of the left rectangular door 7.
[0037] Among them, the horizontal length of the left right-angled trapezoidal door panel 12 should be at least greater than half of the width of the box body 1, and the horizontal length of the left rectangular door panel 7 should be less than the horizontal length of the left right-angled trapezoidal door panel 12. The same applies to the right folding door.
[0038] The limit blocks 17 are welded at the left and right positions of the upward-opening door panel 6 to prevent outward expansion when the left and right folding doors are unfolded.
[0039] The nylon drawstrings 10 are respectively fixed on the left right-angled trapezoidal door panel 12, the right right-angled trapezoidal door panel 14, the left rectangular door panel 7, and the right rectangular door panel 9 by riveting, which is convenient for the operator to open the folding door during operation.
[0040] The water flow trough 2 is pasted on the front end face of the box body 1 above the upper hinge 5 in a glued form. It can divert rainwater to both sides of the distribution box on rainy days to prevent rainwater from entering the distribution box. The 360-degree limiter 16 is installed on the right rectangular door panel 9 by bolts. After the distribution box door is folded and closed, rotate the 360-degree limiter 16 by 90 degrees to limit the upward flipping of the upward-opening door panel 6, thereby preventing the distribution box door from opening during vehicle driving.
[0041] The distribution box has two states: open and closed. Figure 1 In the fully closed state, when the distribution box is to be opened, rotate the 360-degree limiter 16 by 90 degrees to one side, flip the upward-opening door panel 6 upward around the upper hinge 5, and pull the nylon drawstrings 10 fixed on the left right-angled trapezoidal door panel 12 and the right right-angled trapezoidal door panel 14 on the other side. The left and right folding door panels are respectively opened outward around the left hinge 13 and the right hinge 15, so that the left right-angled trapezoidal door panel 12 and the right right-angled trapezoidal door panel 14 form a 90° angle with the front end face of the box body 1, that is, as Figure 3 shown. The left rectangular door panel 7 and the right rectangular door panel 9 are respectively adsorbed on the left right-angled trapezoidal door panel 12 and the right right-angled trapezoidal door panel 14 through the Z-shaped magnetic strips 8. At this time, the limit blocks 17 welded on the upward-opening door panel 6 play a role in preventing the two right-angled trapezoidal door panels on both sides from continuing to expand outward. The upward-opening door panel 6 fits on the hypotenuses of the left right-angled trapezoidal door panel 12 and the right right-angled trapezoidal door panel 14. Then, insert the external cable obliquely upward into the output socket 4 installed on the outgoing panel 3. Then, by respectively pulling the nylon drawstrings 10 fixed on the left rectangular door panel 7 and the right rectangular door panel 9, the left rectangular door panel 7 and the right rectangular door panel 9 are flipped outward around their respective hinges 11, so that the left rectangular door panel 7 forms a 90-degree angle with the left right-angled trapezoidal door panel 12, and the right rectangular door panel 9 forms a 90-degree angle with the right right-angled trapezoidal door panel. The Z-shaped magnetic strips 8 on both sides are adsorbed together, and the upward-opening door panel 6 fits on the hypotenuses of the left right-angled trapezoidal door panel 12 and the right right-angled trapezoidal door panel 14 and the edges of the left rectangular door panel 7 and the right rectangular door panel 9, thus forming an independent operation space protruding from the carriage with the outgoing panel 3. At this time, the distribution box is completely opened, as Figure 2 shown.
[0042] When the tapping box is to be closed, the Z-shaped magnetic strips 8 fixed on the left rectangular door panel 7 and the right rectangular door panel 9 change from the adsorbed state to the separated state. The left rectangular door panel 7 and the right rectangular door panel 9 respectively turn inward around their respective hinges 11, and finally are respectively adsorbed on the left right-angled trapezoidal door panel 12 and the right right-angled trapezoidal door panel 14 through the Z-shaped magnetic strips 8. Then, the left right-angled trapezoidal door panel 12 turns inward around the left hinge 13 until it is parallel to the front end face of the box body 1, and the right right-angled trapezoidal door panel 14 turns inward around the right hinge 15 and fits on the left right-angled trapezoidal door panel 12. Then, the upward-opening door panel 6 turns downward around the upper hinge 5 and fits on the right right-angled trapezoidal door panel 14. In this way, the upward-opening door panel 6, the left folding door, and the right folding door are folded together and flush with the carriage surface; the 360-degree limiter 16 rotatably mounted on the right right-angled trapezoidal door panel 14 fixes and compresses the upward-opening door panel 6, the left folding door (the left right-angled trapezoidal door panel 12, the left rectangular door panel 7, the left hinge 13), and the right folding door (the right right-angled trapezoidal door panel 14, the right rectangular door panel 9, the right hinge 15) together. At this time, the tapping box is completely closed.
[0043] When the present utility model is in the open state, the operations of the tapping box are all carried out in an independent operation space protruding from the carriage, which is composed of the upward-opening door panel 6, the left folding door (the left right-angled trapezoidal door panel 12, the left rectangular door panel 7, the left hinge 13), and the right folding door (the right right-angled trapezoidal door panel 14, the right rectangular door panel 9, the right hinge 15), without occupying the internal space of the carriage, thereby improving the utilization rate of the internal space of the carriage; at the same time, when the Z-shaped magnetic strips 8 on the left rectangular door panel 7 and the Z-shaped magnetic strips 8 on the right rectangular door panel 9 are completely adsorbed and closed, a space is formed that is completely enclosed on all sides except for the bottom inlet line, which can prevent unauthorized personnel from misoperating; secondly, when encountering rainy or snowy weather, it can block the rain and snow from falling on the cable connectors, thereby increasing the service life of the cable connectors and eliminating potential safety hazards. When the present utility model is in the closed state, the upward-opening door panel 6, the left folding door, and the right folding door are folded together and flush with the carriage surface, without affecting the normal driving of the vehicle. At the same time, the utility model has a simple structure, low cost, is easy to manufacture and process, and is light in weight.
[0044] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
