Description

WIRE OUTPUT CAVITY COVER PLATE DEVICE, BASE STATION REMOTE APPARATUS AND ELECTRONIC APPARATUS INCLUDING THE SAME

CROSS-REFERENCE TO RELATED APPLICATION

This application claims the benefit of Chinese Utility Model Application No. 202221229848.8 filed on May 19, 2022 in the China National Intellectual Property Administration, the whole disclosure of which is incorporated herein by reference.

TECHNICAL FIELD

The present disclosure relates to a cover plate locking technology, and in particular, to a wire output cavity cover plate device and a base station remote apparatus including such device.

BACKGROUND

Many electronic and/or electrical apparatuses have a wire output cavity located on its outer surface. For example, power cords, optical fibers, network cables, and so on extend out of the wire output cavity and are connected with other apparatuses. These wires may also be regulated in advance within the wire output cavity, making the wires exposed outside more concise. For example, in the communication field, the base station antenna unit, the remote radio frequency unit and other outdoor apparatuses, need to be connected with each other through wires and then connected with the indoor baseband unit. At this time, good sealing of the wire output cavity can provide effective protection for these outdoor apparatuses.

At present, most of the sealing of the wire output cavity cover plate adopts screw fastening method. For example, after the cover plate on the wire output cavity is covered, using the screws to lock the cover plate and the machine component, and wires such as power supply wires, optical fibers and so on are outputted from the small hole of the wire output cavity. The sealing of the wire output cavity is realized by means of the waterproof and impurity-proof structure such as waterproof adhesive tape.

This screw fastening structure usually needs a plurality of screws, so that the screws shall be installed and fastened one by one manually during in-field installation, which not only consumes too much time but also is not easy to operate, and thus the probability of unreliable screw fastening is also high. When it needs to maintain such as inspecting or replacing the wiring and thus opening the cover, it is also faced with the steps to unscrew multiple screws and then fasten them after operation. Especially in harsh environments, or during aloft work (such as for remote apparatus on the iron tower) , the installation and disassembly of multiple screws not only are inefficient and have low operating safety factor, but also are more likely to cause operational errors.

DETAILED DESCRIPTION

Exemplary embodiments of the present disclosure will be described below with reference to the accompanying drawings. It should be noted that the described embodiments are only some examples of the present disclosure, and are not intended to limit the present disclosure. All other embodiments which are available for those skilled in the art based on the described embodiment without creative labor fall within the protection scope of the present disclosure also.

Embodiments of the present disclosure are described below with reference to the accompanying drawings. Aiming at avoiding or omitting screws for fastening the wire output cover plate, the technicians have tried some solutions. For example, the rotation shaft of the wire output cover plate is fixed on the component main body, and two spanners can be fixed on two sides of the wire output cover plate and pivoted far away from the rotation shaft end, namely close to the end of the wire output holes. Spanner clamping pin flush in position with the wire output holes are located on the component main body, and can be engaged by the spanner, forming the locking to the wire output cavity. However, because the clamping pin is located at the position flush with the wire output holes, the design for the wire output holes is greatly affected.

For example, as the wire output holes are generally arranged in parallel and the wire output cavity has a fixed width, the number of the wire output holes and the intervals between the wire output holes are limited due to the arrangement of locking pins on both sides. Especially, the inner walls of the wire output holes need to be equipped with adhesive tapes to achieve the sealing property, and thus the wire output holes need to occupy a larger space. For example, in order to firmly fix the clamping pin 205 to outside of the wire output cavity, preferably using screw to protrude from the inner wall of the nearest wire output hole, which not only renders a complex structure, but also can affect the sealing of the adhesive tapes of the wire output holes. In order to avoid the influence on the layout of the wire output holes, the present disclosure provides the following specific embodiments that can also realize the sealing of the wire output cavity without screws for fastening.

Referring to FIG. 1 and FIG. 2, one embodiment of the present disclosure provides a wire output cavity cover plate device for using with a component main body 20. The wire output cavity cover plate device and the component main body 20 can form a sealing wire output cavity therebetween. The wire output cavity cover plate device may include a wire output cavity cover plate 40, a wire output cavity cover plate rotation shaft 50 and a cover plate locking device 30. The wire output cavity cover plate 40 includes a first end and a second end opposite to each other, and is pivotably connected with the component main body 20 through the wire output cavity cover plate rotation shaft 50 disposed at the first end of the wire output cavity cover plate 40. When the wire output cavity cover plate 40 is closed and locked by the locking device 30, the wire output cavity 10 can be sealed.

In the embodiment as shown in FIG. 1, the wire output cavity 10 may include at least one wire output hole. The wire output holes in FIG. 1 are shown to be located at the second end of the wire output cavity cover plate 40, and several wires pass through the wire output holes and extend outwards. Due to the locking of the locking device, materials such as waterproof and impurity-proof adhesive tapes on the inner sides of the wire output holes can realize the sealing of the position where the wire output holes are.

FIG. 1 illustrates that the wire output hole 37 is formed by a part of the second end of the wire output cavity cover plate 40 and a part of the component main body 20. For example, the second end of the wire output cavity cover plate 40 has a first cove with a semi-circle shape, as a half wire output hole, and the component main body 20 has a second cove with a semi-circle shape, as a half wire output hole. When the wire output cavity cover plate 40 is closed to the component main body 20, they define a circle wire output hole 37. It is appreciated that the wire output hole 37 may be defined by the wire output cavity cover plate 40 together with the component main body 20, and however, it is not necessary to be the same case as what is shown in FIG. 1. In another embodiment, the first cove of the wire output cavity cover plate 40 may have a circle cove, and the component main body 20 may have no the second cove. Those skilled in the art could configure the first cove and the second cove of the respective wire output cavity cover plate 40 and component main body 20 for providing the wire output hole 37.

FIGS. 6-7 show another embodiment of the present disclosure. In the embodiment, the wire output hole 37 is located in a side, extending between the first end and the second end, of the wire output cavity cover plate 40, and close to the first end.

In another embodiment, the wire output hole 37 is located in a side, extending between the first end and the second end, of the wire output cavity cover plate 40, and close to the second end or the middle segment.

FIG. 2 shows the details of the construction of the cover plate locking device. The cover plate locking device 30 includes a locking portion and a locking pin 31. The locking pin 31 is arranged on the outer side of the wire output cavity cover plate 40 close to the wire output end. The locking portion includes a locking rotation shaft 35 and a hook-shaped clamping knuckle 32 pivotable along with the locking rotation shaft. The hook-shaped clamping knuckle 32 is configured for clamping the locking pin 31 in its hook shape after pivoting so as to lock the wire output cavity cover plate 40 with the component main body 20. The locking rotation shaft 35 is disposed on the component main body 20 and located at the other side of the wire output holes relative to the wire output cavity cover plate. From a plurality of drawings, such as FIG. 1 and FIG. 3, it can be seen that, the locking portion is from a locking root and cross plate below the wire output hole and fixed to the component main body, across the wire output hole, and to the hook-shaped clamping knuckle that is above the wire output hole and corresponds to the locking pin fixed to the outer side of the wire output cavity cover plate. Upper and lower two sides of the wire output hole are pressed by the locking of the clamping knuckle and the pin, providing the sealing at the position of the wire output hole.

In FIG. 2, the position of the locking rotation shaft 35 after being mounted is shown by the rotation shaft hole 21B, and the other rotation shaft hole, namely the one close to the back side of the paper, is not shown. The locking rotation shaft 35 passes through the two rotation shaft holes fixed on the component main body, and the holes are each sized to provide enough support to the locking rotation shaft and to allow the locking rotation shaft 35 to rotate freely therein. Therefore, the locking rotation shaft 35 and the wire output holes are staggered so that the layout of the wire output holes is not affected. Those skilled in the art can also think of using other manners than the illustrated rotation shaft locking holes 21B to realize that the locking rotation shaft 35 is placed on the side of the component main body 20 close to the wire output hole (below the wire output hole as shown in FIG. 2) , namely the opposite side of the wire output cavity cover plate 40.

In one embodiment, the cross section of the locking rotation shaft 35, at least at the position relative to the rotation shaft hole 21B, is circular, and the rotation shaft hole 21B is also circular, so that the locking rotation shaft 35 can rotate freely in it. In one embodiment, the cross section of the middle section of the locking rotation shaft 35 is circular, while the cross section at its tip presents a specific shape according to needs.

In one embodiment, two ends of the locking rotation shaft 35 close to the tips 35A, 35B have a cross section of polygonal. This shape is matched with the shape of the root holes 32A, 32B of the hook-shaped clamping knuckle, such that, when the tips 35A, 35B are sleeved into the root holes 32A, 32B, the hook-shaped clamping knuckle 32 can pivot with the rotation of the locking rotation shaft 35. The cross section of the locking rotation shaft 35 shown in FIG. 2 close to the tips 35A, 35B is a hexagon, and other shapes that can realize this function can be obtained by those skilled in the art.

In order to make the locking rotation shaft 35 after sleeved in the rotation shaft hole 21B is not easy to slide left and right, so that the tips of the locking rotation shaft 35 and the root holes 32A, 32B of the hook-shaped clamping knuckle of the root hole are not out of match, the tips of the locking rotation shaft 35 can be screwed with a positioning nut 34. Cooperating with the positioning nut 34, it is necessary to have an outer screw thread (not shown in the figure) at the tips of the locking rotation shaft 35. Further, an elastic gasket 33 can be disposed between the positioning nut 34 and the root holes 32A, 32B of the hook-shaped clamping knuckle, so that the positioning nut can more permanently and stably lock the position of the locking rotation shaft 35 relative to the root holes 32A, 32B of the hook-shaped clamping knuckle.

In one embodiment, as shown by FIGS. 1-5, the hook-shaped clamping knuckle 32 includes a first hook-shaped clamping knuckle head 321 and a second hook-shaped clamping knuckle head 322, which are respectively located at the left and right sides of the wire output hole and respectively clamp the locking pin 31, thereby firmly fastening the wire output cavity cover plate 40 to the component main body 20. In an embodiment, the hook-shaped clamping knuckle includes only one hook-shaped clamping knuckle head 321 or 322, and a corresponding locking pin is disposed at a side of the wire output hole corresponding to the hook-shaped clamping knuckle head. With that configuration, the sealing between the wire output cavity cover plate 40 and the component main body 20 can be also achieved. All the embodiments as well as the accompanying drawings of the present disclosure are described with the engagement between a pair of locking pins and the first and second clamping knuckle heads (provided on the component main body) , which will not be repeated in the followings. However, it is appreciated that only one clamping knuckle head may be provided in another embodiment of the present disclosure.

In one embodiment, as shown in FIG. 3, the clamping knuckle 32 may have a shape of “U” , that is, include a cross plate 323 between the first clamping knuckle head 321 and the second clamping knuckle head 322. The cross plate 323 is close to the root of the “U” shape of the hook-shaped clamping knuckle, namely located below the wire output holes and thus will not affect the arrangement of the wire output holes. The cross plate 323 between the first and second hook-shaped clamping knuckle heads 321, 322 can strengthen the firmness of the locking connection, so that the hook-shaped clamping knuckle 32 act as a whole to fix the wire output cavity cover plate 40 on the component main body 20 by the first and second hook-shaped clamping knuckle heads 321, 322. Furthermore, due to rigidity of the cross plate 323 and thus brought cross rigidity between the first and second hook-shaped clamping knuckle heads 321, 322, the clamping knuckle 32 can strengthen a lateral rigidity of the wire output cavity cover plate 40 and thus an integral engagement strength of the wire output cavity cover plate 40 and the component main body 20, providing improved sealing of the wire output cavity. Further, from the perspective of installation and maintenance personnel, only one time rotating the hook-shaped clamping knuckle to finish the locking and unlocking on both sides.

In one embodiment, the first clamping knuckle head 321 and the second clamping knuckle head 322 each are protruded inwards near the knuckle tip, as shown in FIG. 4A, such that the segment of the first clamping knuckle head 321 and the second clamping knuckle head 322 near the knuckle tip is enlarged in size. A pivoting radius, about the locking rotation shaft 35, of the hook-shaped clamping knuckle at the enlarged segment is slightly less than a distance between the locking rotation shaft 35 and its corresponding lock pin. The locking rotation shaft corresponding to the lock pin is based on the corresponding position 35B of the rotation shaft locking hole 21B where the rotation shaft is located. When the hook-shaped clamping knuckle 32 snaps the lock pin at the corresponding position into the hook shape, a certain interference fit is generated due to the enlarged segment, and the protrusion has been passed over when the lock pin is completely locked in place, so that the interference fit disappears, and the rebound force of the sealing tapes is provided, replacing that, to ensure the fastening of the wire output hole. If a re-unlocking is required, it still needs to pass the pin over the protrusion of the hook-shaped clamping knuckle by interference fit to decouple it from the hook-shaped clamping knuckle, thereby avoiding loosening/disengagement brought by extreme weather or environment influence caused by earthquake, typhoon, temperature sudden change and so on. Moreover, because the interference fit makes it difficult to manually decouple the hook-shaped clamping knuckle and open the wire output cavity without using of the external tool, it can also ensure the wire output cavity to be not subject to man-made damage.

It can be understood that avoiding man-made damage is only the additional effect of the above embodiment, the more stable locking formed under the interference fit itself provides the further beneficial effect. Hereinafter, the embodiments to be described will mainly emphasize the structure of locking and unlocking the hook-shaped clamping knuckle by cooperating with an external tool. Within the scope of those skilled in the art can think of, a grippable extension part of the hook-shaped clamping knuckle provided on the component main body, such as a spanner, also can realize the main purpose of the present disclosure, and a further improvement through the certain embodiments provides a further beneficial effect.

In one embodiment, one side tip of the locking rotation shaft 35 is provided with a polygonal inner hole, and FIG. 2 shows the tip of the rotation shaft close to the outer side, in which it is also shown as a hexagon. The inner hole is shaped so that the locking rotation shaft 35 is driven to pivot by means of swinging a rocking handle 61 after the rocking handle 61 is inserted into the inner hole. At this time, the tip of the rotation shaft 35 close to the inner side is still disposed with outer screw thread and the positioning nut 34 matched therewith. Provision of the positioning nut 34 at a single side of the rotation shaft 35 also can realize the positioning of the root holes 32A, 32B of the hook-shaped clamping knuckle to the rotation shafts 35A, 35B. As to the rotation shaft 35 shown in FIG. 2, when assembling, its tip with outer screw thread (namely the one close to the end 35A) is inserted from the hole 32B, passes through the hole 32A, and then, is screwed with the positioning nut 34. At this time, the tip with the polygonal inner hole is blocked outside the root hole 32B of the hook-shaped clamping knuckle 32. Cooperating with the role of the positioning nut 34, the positioning of the rotation shafts 35A, 35B by the root holes 32A, 32B of the hook-shaped clamping knuckle 32 is realized.

The external rocking handle shown in FIG. 2 is a right-angled hexagonal stick 61. As shown in FIG. 4, the short end of the right-angled hexagonal stick 61 is inserted into the inner hole. As shown in FIG. 4, by rotating the long end of the hexagonal stick 61 to drive the locking rotation shaft 35 to rotate, the hook-shaped clamping knuckle 32 is driven to pivot around the locking rotating shaft 35 (the locking rotating shaft 35 also rotates at the same time) , so that the locking pin 31 is clamped into the hook shape, or get out of the hook shape. Especially when opening the wire output cavity, since the right-angled hexagonal stick provides a longer arm of force, it only needs small force to disengage the hook-shaped clamping knuckle under the interference fit from the locking pin.

In another embodiment shown in FIG. 5, a protrusion, having a sleeve hole 36 therein, is provided on a back of the hook-shaped clamping knuckle 32 protruded towards away from the component body 20. The sleeve hole 36 is configured to allow insertion of an external handle 62 to pivot the hook-shaped clamping knuckle 32 around the locking rotation shaft 35 by the external handle 62. For example, in the embodiment as shown in FIG. 5, the extending direction of the sleeve hole 36 is tangent with the rotating direction of the hook-shaped clamping knuckle 32. However, the extending direction of the sleeve hole 36 may be a direction different from the direction as shown. After inserting the external handle into the sleeve hole, rotation of the hook-shaped clamping knuckle 32 can be realized. The external handle may be a crowbar 62. By pulling the crowbar 62 to pivot around the locking rotating shaft 35 (the locking rotating shaft 35 also rotates at the same time) along the movement track direction of the hook-shaped clamping knuckle, the locking and unlocking of the hook-shaped clamping knuckle 32 relative to the pin 31 can be realized in a labour-saving manner. In this embodiment, there is no need to provide a polygonal inner hole at a side of the tip of the locking rotation shaft 35. The positioning nuts 34 (or with additional gaskets) are adopted at both tips of the locking rotation shaft 35, or else, on the tip at only one side the positioning nut 34 is adopted and on the tip at the other side a hole having a size greater than the cross section of the root holes 32A, 32B of the hook-shaped clamping knuckle is adopted.

The above two embodiments only provide two kinds of structure in which the tool independent of the cover plate locking device 30 is used for locking and unlocking the cover plate. Those skilled in the art can think of other structures that need to use external tools that are not fixed on the locking device to realize the locking and unlocking of the cover plate, all of which are within the protection scope of the present disclosure.

The interference fit when rotating and locking can make the locked wire output cavity cover plate not easy to loosen, but on the other hand, when rotating to lock and unlock, it is necessary to make the combination between the locking pin 31 arranged on the outer side of the cover plate and the wire output cavity cover 40 stronger, so that it can withstand the pulling force brought by the interference fit and will not bend the locking pin 31 at a weak point after multiple rotations. In one embodiment, the pin structure of the cover plate locking device as shown in FIG. 2, includes not only a locking pin 31, but also a pin sleeve 31' disposed on the locking pin 31. For the sake of integrity and not easy to bump, after assembling, the locking pin 31 protruding from the cover plate 40 and the pin sleeve 31' sleeved on the locking pin 31 are in the groove on the outer side of the cover plate, with the outer edge of the sleeve 31' being flush with the edge of the cover plate. After rotating with the hook-shaped clamping knuckle 32, the locking pin 31 is clamped in the hook shape, at this time, the clamping knuckle 32 is pressed into contact with the pin sleeve 31', which drives the pin sleeve 31' to rotate on the locking pin 31.

When the hook-shaped knuckle 32 pivots, the rolling friction between the inside of the hook and the pin sleeve 31' is more labor-saving than the sliding friction between the hook and the locking pin 31 directly, so the combination strength requirements of the locking pin 31 and the outlet cavity cover 40 can also be lowered. From another point of view, addition of the pin sleeve 31' that can roll on the locking pin 31 can also increase the service life of the cover plate, avoiding the pin is broken at its weak point (mostly the position where it is inserted and fixed on the side wall of the outlet cavity cover plate) .
