Detailed Description

Exemplary embodiments of the present invention will be described below with reference to the accompanying drawings. It should be noted that the described embodiments are only examples of the present invention, and are not intended to limit the present invention. All other embodiments that can be obtained by a person skilled in the art without any inventive step based on the described embodiments also fall within the scope of protection of the present invention.

Embodiments of the present invention are described below with reference to the drawings. Aiming at avoiding or omitting the use of screws for fastening the wire outlet cover plate, technicians try some solutions, for example, fixing a rotating shaft of the wire outlet cover plate on a component body, and fixing two wrenches on two sides of the wire outlet cover plate and far away from the rotating shaft end, namely, one end close to a wire outlet hole. The wrench clamping pin which is flush with the outlet hole is positioned on the component body and can be occluded by a wrench to form locking of the outlet cavity. However, the design of the outlet hole is greatly affected by the position of the detent pin which is flush with the outlet hole.

For example, the outlet holes are generally arranged in parallel, the number of the outlet holes and the interval between the outlet holes are limited due to the fixed width of the outlet cavity, and particularly, the inner wall of the outlet hole needs to be provided with an adhesive tape to realize sealing, so that the outlet holes need to occupy larger space. For another example, in order to fix the locking pin 205 more firmly outside the outlet cavity, it is preferable to use a screw to extend from the inner wall of the outlet hole closest to the locking pin, which not only complicates the structure, but also may affect the tightness of the rubber strip in the outlet hole. In order to avoid the influence to the wire hole overall arrangement, the utility model provides a do not need fastening screw just can realize being qualified for the next round of competitions the cavity seal's concrete embodiment as follows equally.

Referring to fig. 1 to 2, an embodiment of the present invention provides an outlet cover plate device for realizing the tightness of the outlet cavity 10 formed between the outlet cover plate 40 and the component body 20. The device comprises a wire outlet cavity cover plate 40, a wire outlet cavity cover plate rotating shaft 50 and a cover plate locking device 30. When the outlet cavity cover plate 40 is closed and locked by the locking and clamping device 30, the sealing of the outlet cavity 10 can be provided. As can be seen in fig. 1, the wire outlets are located at opposite ends of the cover plate pivot 50, and the cables extend outwardly through the wire outlets. Due to the locking of the locking device, the waterproof and impurity-proof rubber strips and other substances on the inner side of the wire outlet hole can realize the sealing of the position of the wire outlet hole.

Fig. 2 shows the details of the structure of the cover latch device. The cover latching device 30 includes a latching body and a latching pin 31. The latch pin 31 is arranged on the outer side of the outlet cavity cover plate 40 close to the outlet end. The locking body comprises a locking rotating shaft 35 and a hook-shaped locking tongue 32 which can rotate along with the locking rotating shaft. The hook-shaped latch 32 is used for locking the latch pin 31 into a hook after rotation, so that the outlet cavity cover plate 40 is locked with the component body 20. The locking rotating shaft 35 is arranged on the component body 20 and is positioned on the other side of the wire outlet hole relative to the wire outlet cavity cover plate. As can be seen from a plurality of figures, for example, fig. 1 and 3, the latch body spans the wire outlet from the latch root fixed on the fastener body below the wire outlet to the hook-shaped latch tongue above the wire outlet corresponding to the latch pin fixed on the outer side of the wire outlet cavity cover plate, and the latch tongue and the pin are locked to tightly press the upper and lower surfaces of the wire outlet, thereby sealing the position of the wire outlet.

In fig. 2, the position of the lock latch spindle 35 after installation is shown by the spindle latching hole 21B, and the spindle latching hole on the other side, i.e., the inner side of the screen, is not shown. The latch shaft 35 penetrates the two shaft engaging holes fixed to the member body, and has a diameter such that sufficient support can be provided for the latch shaft and the latch shaft 35 can freely rotate therein. Therefore, the locking rotating shaft 35 and the wire outlet hole are arranged in a staggered mode, so that the layout of the wire outlet hole is not influenced as much as possible. It will be appreciated by those skilled in the art that the latch spindle 35 can be positioned on one side of the outlet opening fastener body 20 (below the outlet opening as shown in fig. 2), i.e., on the other side of the outlet housing cover 40, by other means than the spindle capture hole 21B shown.

In one embodiment, the lock catch shaft 35 is circular in cross-section at least at the location relative to the shaft detent hole 21B, and the shaft detent hole 21B is also circular so that the lock catch shaft 35 can freely rotate therein. In one embodiment, lock latch spindle 35 has a circular cross-section in its middle section until the proximal tip assumes a particular shape as desired.

In one embodiment, lock latch spindle 35 has a polygonal cross-section at both ends near the

distal tips

35A, 35B. The shape of the hook-shaped latch is matched with the shape of the

root holes

32A and 32B of the hook-shaped latch, so that when the position close to the

ends

35A and 35B is sleeved into the

root holes

32A and 32B, the hook-shaped latch 32 can rotate along with the rotation of the lock latch rotating shaft 35. The proximal ends 35a,35b of latch pivot 35 shown in fig. 2 are hexagonal in cross-section, although other shapes will occur to those of skill in the art to accomplish this function.

In order to prevent the lock-latch rotating shaft 35 from sliding left and right after being sleeved in the rotating shaft clamping hole 21B, the position near the tip of the lock-latch rotating shaft 35 is not dislocated with the

root holes

32A and 32B of the hook-shaped latch, and a positioning nut 34 can be screwed at the tip of the lock-latch rotating shaft 35. The locking shaft 35 is externally threaded (not shown) at the end thereof for engaging the retaining nut 34. Furthermore, a resilient washer 33 may be positioned between the retainer nut 34 and the location that engages the hook

latch root holes

32A,32B to enable the retainer nut to more permanently and securely retain the latch pivot 35 relative to the location of the hook

latch root holes

32A, 32B.

In one embodiment, the number of the hook-shaped latch 32 is two, and the two latch are respectively positioned at the left side and the right side of the outlet hole. The air tightness of the wire outlet cavity can be realized only by arranging a hook-shaped clamping tongue and a corresponding locking pin on one side of the wire outlet hole. In order to achieve a better sealing effect, the embodiments and the embodiment drawings mentioned in the present invention are all described by respectively setting a pair of locking pins (and setting on the firmware body) at both sides of the wire outlet cavity cover plate, and the description is omitted later.

In one embodiment, as shown in fig. 3, a bar is connected between the two hook-shaped latches 32, and the bar is close to the root of the hook-shaped latches, i.e., is located below the outlet hole without affecting the arrangement. The cross bar between the two hook-shaped latch tongues 32 can enhance the firmness of the latch, so that the two hook-shaped latch tongues as a whole fix the outlet chamber cover plate 40 on the component body 20. Furthermore, from the operation angle of installation and maintenance personnel, the locking and unlocking of the two sides can be completed only by rotating the hook-shaped clamping tongue once.

In one embodiment, the hook-shaped latch 32 projects inwardly near the tip of the latch, as shown in FIG. 4A, such that a section of the latch near the tip of the latch widens. The rotating radius of the hook-shaped latch at the protrusion is slightly smaller than the distance between the lock rotating shaft 35 and the lock pin corresponding to the lock rotating shaft, and the lock rotating shaft corresponding to the lock pin is based on the corresponding position 35B of the rotating shaft clamping hole 21B where the rotating shaft is located. When the hook-shaped latch tongue 32 latches the latch pin at the corresponding position into the hook, a certain interference fit is generated due to passing through the protrusion, and the latch tongue passes over the protrusion when being completely latched in place, so that the interference disappears, and the fastening at the wire outlet is ensured by the rebound force of the sealing rubber strip instead. If the lock is unlocked again, the pin still needs to pass through the bulge of the hook-shaped clamping tongue through interference fit to be separated from the hook-shaped clamping tongue, so that the lock clamp is prevented from loosening caused by extreme weather or environmental influences such as earthquakes, typhoons, sudden temperature changes and the like. In addition, due to the interference fit, the hook-shaped clamping tongue is difficult to be pulled open manually without an external tool to open the wire outlet cavity, and the wire outlet cavity can be prevented from being damaged manually.

It will be appreciated that the avoidance of human damage is merely an additional effect of the above described embodiment, the more secure locking created under the interference fit, in itself already providing a further benefit. The embodiments to be described below focus primarily on the structure for engaging an external tool to effect locking and unlocking of the hook-shaped latch. It will be appreciated by those skilled in the art that the primary object of the invention is also achieved by a grippable extension of a hook-like latch provided on a body of a component, such as a wrench, and that further advantages are provided by further improvements in certain embodiments described above.

In one embodiment, the latch spindle 35 has a polygonal bore at one end, shown in FIG. 2 as the spindle outboard end, also shown in FIG. 2 as a hexagon. The shape of the inner hole enables the lock clamping rotating shaft 35 to be driven to rotate through the shaking of the rocking handle after the external rocking handle is inserted. At this point, the inner end of the shaft 35 is still externally threaded and engaged with the retaining nut 34. The positioning of the hook-shaped clamping

tongue root holes

32A and 32B on the

rotating shafts

35A and 35B can also be realized by using the positioning nut 34 on one side of the rotating shaft 35. As shown in FIG. 2, spindle 35 is assembled by inserting the externally threaded distal segment (i.e., near the end 35A) through the bore 32B and threading through 32A and tightening retaining nut 34. At this time, the end with polygonal inner hole is clamped outside the hook-shaped latch root hole 32B, and the hook-shaped

latch root holes

32A and 32B are matched with the action of the positioning nut 34 to realize the positioning of the

rotating shafts

35A and 35B.

The external handle shown in fig. 2 is a right angle hexagonal stick 61. As shown in fig. 4, the short end of the right-angled hexagonal rod 61 is inserted into the inner hole, and as shown in fig. 4A, the long end of the hexagonal rod is rotated to rotate the locking and locking rotating shaft 35, so as to rotate the hook-shaped locking tongue 32 around the locking and locking rotating shaft 35 (and simultaneously the locking and locking rotating shaft 35 is rotated), and the locking and locking pin 31 is locked into the hook or released from the hook. Particularly, when the outlet cavity is opened, the right-angle hexagonal rod provides a longer force arm, so that the hook-shaped clamping tongue in interference fit can be driven to be separated from the locking and clamping pin only by a small force.

In another embodiment as shown in fig. 5, a fixed sleeve hole 36 is extended from the back of the hook-shaped latch 32, and the extending direction of the fixed sleeve hole is tangential to the rotating direction of the hook-shaped latch 32, and the hook-shaped latch 32 can be rotated after an external handle is inserted into the sleeve hole, wherein the external handle is a crow bar 62. By turning the crow bar 62 along the movement locus of the hook-shaped latch about the latch rotating shaft 35 (and simultaneously turning the latch rotating shaft 35), the locking and unlocking of the hook-shaped latch 32 with respect to the pin 31 can be realized in a labor-saving manner. In this embodiment, it is not necessary to provide a polygonal inner hole at one end of the locking/locking shaft 35, and the positioning nut 34 (or a washer may be added) may be used at both ends of the locking/locking shaft 35, or the positioning nut 34 may be used only at one end and the other end may have a cross section with a diameter larger than the diameter of the hook-shaped latch root holes 32a and 32b.

The above two embodiments only provide two structures that the cooperation is independent of the instrument outside the apron locking device 30 to lock and unlock the apron, and the person skilled in the art can think that other structures that need not fix the external tool on the locking device with the help of itself and can realize the locking and unlocking of apron are all within the scope of protection of the utility model.

The locked wire outlet cavity cover plate is not easy to loosen due to the interference fit during rotation locking, but on the other hand, the pin 31 arranged on the outer side of the cover plate and the wire outlet cavity cover plate 40 are required to be combined more firmly during rotation locking and unlocking, so that the pulling force caused by the interference fit can be borne, and the pin 31 cannot be bent at a weak position after being rotated for multiple times. In one embodiment, the pin structure of the cover locking device shown in fig. 2 includes not only the pin 31, but also a pin sleeve 31' disposed on the pin 31. In order to be integral and not easy to bump, after assembly is completed, the pin 31 extending out of the cover plate 40 and the pin sleeve 31' sleeved on the pin 31' are positioned in the groove on the outer side of the cover plate, and the outer edge of the sleeve 31' is flush with the edge of the cover plate. After rotating with the hook-shaped latch 32, the pin 31 is latched into the hook, and at the moment, the latch is in pressing contact with the pin sleeve 31 'to drive the pin sleeve 31' to rotate on the pin 31.

Because the rolling friction between the inner side of the hook-shaped latch 32 and the pin sleeve 31' is more labor-saving than the sliding friction between the hook of the hook-shaped latch and the pin 31, the requirement on the bonding strength between the pin 31 and the wire outlet cavity cover plate 40 can be reduced. From another perspective, the addition of the pin sleeve 31' that can roll on the pin 31 also increases the useful life of the cover plate, avoiding the pin breaking at its weak points (mostly at the points where it is inserted into and fixed to the side wall of the outlet chamber cover plate).

For the sake of simplicity, the component body provided in the above embodiment drawings belongs to the base station remote equipment, such as the base station antenna unit, the remote rf unit, etc., and the component body shown in fig. 1 to 5 is a part of the heat dissipation fin of the base station outdoor equipment. Those skilled in the art will appreciate that the components of the outlet cover device in the above embodiments may be disposed outside other electronic and electrical devices where appropriate. The structure can be used for realizing the screwless locking of the cover plate when the wire outlet cavity which needs to be closed and is positioned on the outer surface is provided, and the influence on the arrangement of wire outlet holes is not needed to be considered.
