As shown in fig. 1, taking a connection device as an example, the male connector 100 may be installed in the middle of the LED box a, and correspondingly, the female connector 200 is also installed in the middle of the LED box B. When the LED boxes A and B are spliced, the male end connecting piece 100 on the LED box A and the female end connecting piece 200 on the LED box B are aligned, and then the male end connecting piece 100 and the female end connecting piece 200 are connected with each other, so that the connection of the LED boxes A and B is realized.
The structures of the male and female connectors according to the embodiments of the present invention will be described in detail.
Specifically, referring to fig. 3 to 5, the male connector 100 includes a male base 11, a driving assembly 12, and a lock cylinder 13.
For example, the male end base 11 may include a bearing portion 111 and a protrusion 112 extending from a side of the bearing portion 111, the protrusion 112 being provided with a screw hole 11a.
The drive assembly 12 includes a first shaft 121, a second shaft 122, a first gear 123, and a second gear 124. Wherein the first rotation shaft 121 and the first gear 123 are fixed, that is, the first gear 123 is fixed on the first rotation shaft 121, and the first rotation shaft 121 serves as a driving shaft such that the first gear 123 rotates with the rotation of the first rotation shaft 121. The second rotating shaft 122 is fixed to the second gear 124, that is, the second rotating shaft 122 is used as an output shaft, and is fixed to the second gear 124, so that the second rotating shaft 122 rotates along with the rotation of the second gear 124. The first gear 123 and the second gear 124 are meshed.
Further, for ease of operation, the drive assembly 12 may also include a first connecting arm 125, a second connecting arm 126, and a handle 127. Wherein, one end of the first connecting arm 125 is connected with one end of the first rotating shaft 121, the other end of the first connecting arm 125 is connected with one end of the handle 127, one end of the second connecting arm 126 is connected with the other end of the first rotating shaft 121, and the other end of the second connecting arm 126 is connected with the other end of the handle 127. Thus, when the first shaft 121 needs to be rotated, the handle 127 may be used to operate, for example, as shown in fig. 5, when the first shaft 121 needs to be rotated in the direction of the dashed arrow EF, the handle 127 may be pushed in the direction of the lock head 13, so that the first shaft 121 rotates in the direction of EF, thereby facilitating the operation.
In addition, the drive assembly 12 may also include a protective housing 128. The protective shell 128 is fixed on the male end base 11, specifically can be fixed on the bearing part 111 by a screw connection or the like, and covers the first gear 123 and the second gear 124, so that not only can the protection function be achieved, but also the male end connector 100 can be more attractive.
The lock cylinder 13 includes a screw 131 and a lock head 132 connected to each other. The screw 131 and the locking head 132 may be integrally formed, or may be separate components. When the screw 131 and the lock cylinder 132 are separate components, they may be coupled together by screwing, riveting, welding, or the like. The screw 131 has a hollow cavity inside, and the outer surface of the hollow cavity is provided with threads 1311 matching with the threaded hole 11 a. The end of the screw member 131 far away from the lock head 132 is opened, so that the screw member 131 is sleeved on the second rotating shaft 122, as shown in fig. 5, that is, the second rotating shaft 122 is inserted into the hollow cavity of the screw member 131 from the opening end of the screw member 131, and at this time, the second rotating shaft 122 is clamped with the inner wall of the screw member 131.
For example, as shown in fig. 4, a bar-shaped groove 12a extending along the length direction of the second rotating shaft 122 may be disposed on the second rotating shaft 122, correspondingly, a bar-shaped bump is disposed on the inner wall of the threaded member 131, and when the second rotating shaft 122 is inserted into the threaded member 131, the bar-shaped groove 12a of the second rotating shaft 122 is clamped with the bar-shaped bump of the threaded member 131, so that when the second rotating shaft 122 rotates, the threaded member 131 can be driven to rotate, and the whole lock cylinder 13 can be rotated. In other embodiments, a bump may be disposed on the second rotating shaft 122, and a groove may be disposed on an inner wall of the screw member 131, so as to implement the locking between the second rotating shaft 122 and the screw member 131.
Wherein at least part of the screw member 131 is inserted into the screw hole 11a such that at least part of the threads on the outer surface of the screw member 131 can be screwed with the threads in the screw hole 11 a.
Wherein, in order to facilitate the installation of the driving assembly 12 and make the product more beautiful, a mounting groove may be provided on the bearing portion 111 of the male end base 11 to place the driving assembly 12. For example, mounting grooves 11b, 11c, 11d may be provided on the bearing portion 111 of the male end base 11, wherein the mounting groove 11b is used for placing the first rotation shaft 121, the mounting groove 11c is used for placing the first gear 123, and the mounting groove 11d is used for placing the second gear 124. Wherein, the positions of the mounting groove 11c and the mounting groove 11d are configured such that the first gear 123 and the second gear 124 are meshed when the first gear 123 and the second gear 124 are placed in the mounting groove 11c and the mounting groove 11d, respectively.
When the male end connector 100 is assembled, the first gear 123 may be fixed on the first rotating shaft 121, the second rotating shaft 122 may be fixed on the second gear 124, and then the lock cylinder 13 may be sleeved on the second rotating shaft 122 through the screw member 131, and the elongated groove 12a on the second rotating shaft 122 may be engaged with the elongated protrusion on the inner wall of the screw member 131. Thereafter, the locking head 132 of the lock cylinder 13 is inserted into the screw hole 11a, and with the insertion of the locking head 132, at least part of the screw member 131 is also inserted into the screw hole 11a until the second gear 124 can be placed in the mounting groove 11d, and then the first rotation shaft 121 and the first gear 123 are also placed in the corresponding mounting grooves. Thereafter, the protective case 128 is covered on the male terminal base 11, and the first connecting arm 125, the second connecting arm 126, and the handle 127 are mounted, whereby the male terminal connector 100 can be assembled.
In this embodiment, with reference to fig. 2, the working principle of the male connector 100 is as follows: when the handle 127 is required to be connected with the female end connector 200, the handle 127 can be pushed continuously in the direction of the lock cylinder 13, and the first rotating shaft 121 rotates in the EF direction, so that the first gear 123 is driven to rotate, the first gear 123 can drive the second gear 124 to rotate, and the second rotating shaft 122 is driven to rotate. Under the cooperation of the second rotating shaft 122 and the threaded member 131, the threaded member 131 rotates in the threaded hole 11a along with the rotation of the second rotating shaft 122, so that the threaded member 131 moves in the threaded hole 11a continuously towards the direction of the female end connecting member 200, thereby pushing the tapered end 132 of the lock cylinder 13 to extend continuously towards the female end connecting member 200 and further connect with the female end connecting member 200, and at this time, the threaded member 131 is fixed in the threaded hole 11a through the threads of the outer surface, so that the locking of the connecting device can be realized.
When the handle 127 is required to be separated from the female connector 200, the handle 127 can be pushed in the opposite direction of the lock cylinder 13, so that the first rotating shaft 121 rotates in the FE direction, and the threaded member 131 can be driven to continuously move in the opposite direction of the female connector 200, so that the lock head 132 is retracted, the lock head 132 is separated from the female connector 200, and the locking of the connecting device can be released, so that the connecting device is in a non-locking state.
Wherein, an operation identifier may be set on the male connector 100, for example, as shown in fig. 3, an operation identifier of "LOCK" and "UNLOCK" may be set on the protrusion 112 of the male base 11, and when the handle 127 is pushed in the direction indicated by "LOCK", the locking of the connection device may be achieved, and when the handle 127 is pushed in the direction indicated by "UNLOCK", the locking of the connection device may be released.
In one embodiment, the locking head 132 may be secured to the female base by a securing assembly.
In particular, referring to fig. 6-8, the female connector 200 may include a female base 21 and a securing assembly 22. The female end base 21 is provided with a first lock hole 21a, and further, the female end base 21 includes a carrying portion 211 and a side plate 212 extending vertically from a side edge of the carrying portion 211, wherein the first lock hole 21a is disposed on the side plate 212.
The fixing assembly 22 includes a fixing piece 221, a locking piece 222, an elastic member 223, and a housing 224. The fixing piece 221 is provided with a second locking hole 22a, and the locking piece 222 is provided with a third locking hole 22b. The housing 224 includes a bottom 2241 and a side wall 2242 that surrounds the bottom 2241. The fixing piece 221 is fixed on the side wall 2242 of the housing 224, for example, by screwing or riveting, so that the fixing piece 221 and the housing 224 jointly enclose a containing space, and the locking piece 222 is placed in the containing space.
Wherein, the locking piece 222 is provided with an operation portion 2221, and the operation portion 2221 protrudes from the accommodating space to facilitate operation.
As shown in fig. 8, the elastic member 223 may be a spring or a spring piece, etc., and the elastic member 223 is pressed between the lock piece 222 and a side wall 2242 of the housing 224, and based on the view shown in fig. 8, the side wall 2242 is a bottom wall of the housing 224, thereby generating elastic force in the NM direction to the lock piece 222, so that the lock piece 222 is pressed against another opposite side wall 2242 of the housing 224, based on the view shown in fig. 8, the other opposite side wall 2242 is a top wall of the housing 224, thereby fixing the lock piece 222 between the bottom wall and the top wall of the housing 224.
The housing 224 may further include a cover 2243. The bottom 2241 of the housing 224 extends outwards to form a groove 2244, the cover 2243 is also in a groove structure, and one side of the opening of the groove of the cover 2243 is inserted into the groove 2244, and a fourth lock hole 22c is formed in the bottom of the cover 2243 corresponding to the third lock hole 22 b.
Wherein, referring to fig. 4, the top of the tapered end 132 of the lock cylinder 13 is a tapered body, the shape of the third lock hole 22b is similar to that of the bulb, the upper end opening area is larger, the lower end opening area is smaller, and the shape of the lower end opening area is matched with that of the tapered end 132. Of course, the third lock hole 22b may have the same size and shape as the second lock hole. The tip of the lock head 132 may be a cylinder or the like, and is not limited thereto.
When the elastic member 223 applies an elastic force to the locking piece 222 along the NM direction, such that when the locking piece 222 abuts against the top wall of the housing 224, a part of the opening area of the third locking hole 22b is communicated with a part of the opening area of the second locking hole 22a, other part of the opening area of the third locking hole 22b is blocked by the fixing piece 221, and other part of the opening area of the second locking hole 22a is blocked by the locking piece 222.
The fixing assembly 22 is located on the carrying portion 211, wherein the fixing piece 221 is located on a side adjacent to the side plate 212, and the first locking hole 21a and the second locking hole 22a are correspondingly disposed, that is, the second locking hole 22a and the first locking hole 21a are aligned in position, and the sizes and shapes of the two locking holes can be the same. The housing 224 is fixed to the side plate 212, i.e., the fixing piece 221 and the locking piece 222 are located between the side plate 212 and the housing 224.
The lock head 132 is larger than the partial opening area of the third lock hole 22b, that is, the opening area of the third lock hole 22b, which is in communication with the second lock hole 22a, and the lock head 132 is provided with a slot 1321. When the locking head 132 is driven to protrude toward the female connector 200 by the driving assembly 12, the locking head 132 sequentially passes through the above-described partial opening areas of the first locking hole 21a, the second locking hole 22a, and the third locking hole 22b as the locking head 132 is continuously moved. Since the size of the locking piece 132 is larger than the above-mentioned partial opening area of the third locking hole 22b, when the locking piece 132 passes through the partial opening area, the pressing locking piece 222 is moved toward the MN direction, so that more opening area of the third locking hole 22b can be aligned with the second locking hole 22a, and the shielded opening area is reduced, so that the locking piece 132 can pass through the third locking hole 22b. When the top of the cone located in front of the slot 1321 in the lock 132 passes through the third lock hole 22b, the lock piece 222 is not pressed by the lock 132, and the lock piece 222 moves along the NM direction under the elastic force of the elastic member 223, so as to be clamped in the slot 1321 of the lock 132, and further fix the lock 132 on the female end base 21.
The top of the tapered end 132 located in front of the slot 1321 passes through the third lock hole 22b and then penetrates into the fourth lock hole 22c of the cover 2243 to perform a limiting function.
In the above manner, the locking head 132 may be fixed to the female connector 200 to achieve connection of the male connector 100 and the female connector 200.
More specifically, when two LED housings are to be spliced, the handle 127 of the driving assembly 12 is pushed in the direction indicated by "LOCK" on the protrusion 112 to drive the locking head 132 to move toward the female connector 200 until sequentially passing through the first locking hole 21a, the second locking hole 22a and the third locking hole 22b on the female connector 200, and after the top of the cone located in front of the locking groove 1321 in the locking head 132 passes through the third locking hole 22b, the locking piece 222 is clamped in the locking groove 1321 of the locking head 132 under the elastic force of the elastic member 223, so that the locking head 132 can be fixed on the female base 21, and the screw member 131 of the locking post 13 is fixed in the threaded hole 11a through the external screw thread thereof, thereby splicing the two LED housings together.
When the two LED cases need to be detached, the operation portion 2221 of the locking piece 222 is pressed along the MN direction, so that the locking piece 222 is not clamped in the clamping groove 1321 on the locking head 132 any more, so as to release the clamping restriction on the locking head 132, and then the handle 127 is pushed along the direction indicated by "UNLOCK", so as to drive the locking head 132 to retract toward the male connector 100 and disengage from the female connector 200, thereby detaching the two LED cases.
In other embodiments, the locking head may be fixed in the first locking hole through the cooperation of the locking head and the first locking hole instead of using the fixing component, for example, the first locking hole may be configured as a threaded hole, and the outer surface of the locking head is provided with threads matched with the first locking hole, so that when the locking head is inserted into the first locking hole, the locking head is fixed in the first locking hole through the threads on the outer surface of the locking head.
Therefore, by the connecting device provided by the embodiment of the application, the splicing and the splitting of the two LED boxes can be realized by pushing the handle 127 to rotate the first rotating shaft 121, so that the disassembly and the assembly between the boxes can be realized quickly, time and labor are saved, and the tool-free operation can be realized.
The embodiment of the invention also provides an LED display screen, which comprises a plurality of LED boxes and a connecting device for connecting the LED boxes, wherein the connecting device is the connecting device in any embodiment.
The foregoing is only the embodiments of the present application, and therefore, the patent scope of the application is not limited thereto, and all equivalent structures or equivalent processes using the descriptions of the present application and the accompanying drawings, or direct or indirect application in other related technical fields, are included in the scope of the application.
