Referring to fig. 1, the present embodiment provides a thimble-side pin front maintenance LED display screen box 200. Referring to fig. 8, the case 200 is configured to be mounted on the back frame 300, and in particular, to be in contact with the elastic pieces 301 on the back frame 300, thereby forming an LED display screen.
Referring to fig. 2, the case 200 includes a frame 2, an LED module 3, a side latch device 4, and a side latch device 5.
In the present embodiment, the frame 2 is used for fixing the LED module 3, the side latch device 4 and the side latch device 5. The LED module 3 is used for displaying information. The side latch means 4 and the side latch means 5 are both adapted to contact the resilient plate 301 of the back frame 300, thereby mounting the box 200 on the resilient plate 301 of the back frame 300. The side bolt device 4 and the side spring pin device 5 are both fixed on the frame 2 and are respectively positioned on different sides of the frame 2; specifically, the side bolt device 4 and the side spring pin device 5 are respectively located on two opposite edges of the frame 2, so that the side bolt device 4 on one edge can be installed firstly, and then the side spring pin device 5 on the opposite edge is installed, so that the operation is convenient.
Referring to fig. 1, each case 200 includes at least one LED module 3. In the present embodiment, the housing 200 includes four LED modules 3. The front surface of at least one LED module 3 is provided with a through hole 30. The through hole 30 is used to detach the case 200 in front of the LED display screen. In the present embodiment, the front surfaces of the four LED modules 3 are provided with one through hole 30. In other embodiments, the front surface of the LED module 3 is provided with a plurality of through holes 30.
Referring to fig. 3, the side latch device 4 includes a knock pin 41, a side latch 42, and a latch holder 43.
Referring to fig. 4, the top pin 41 and the side pin 42 are movably inserted into the pin seat 43; specifically, the pin holder 43 is provided with two through holes in which the knock pin 41 and the side pin 42 are respectively placed. The first end 41A of the knock pin 41 is in elastic contact with the pin holder 43; specifically, the first end portion 41A is in contact with one surface of the latch base 43 through an elastic member. The first end 41A of the knock pin 41 is aligned with the through hole 30 so that the knock pin 41 can be touched by a tool in front of the LED display screen. The middle part 41M of the top pin 41 is inserted into the side bolt 42; specifically, the side latch 42 is provided with a hole, and the middle part 41M of the top latch 41 is located in the hole; the first end 41A and the second end 41B of the knock pin 41 are located on both sides of the side plug pin 42, respectively. The first end 42A of the side latch 42 is exposed from the latch seat 43 and is used for contacting with the elastic sheet 301 on the back frame 300, so as to fix the box body 200 on the elastic sheet 301 of the back frame 300. The second end 42B of the side latch 42 is in elastic contact with the latch seat 43; specifically, the second end portion 42B is in contact with one surface of the latch base 43 through an elastic member.
The middle portion 41M of the knock pin 41 is provided with a first-stage pin body 411 and a second-stage pin body 412. Referring to fig. 5, the side latch 42 has a first pin hole 421, a second pin hole 422 and a sinking platform 423; referring to fig. 4, since the two pin holes are communicated, the middle portion 41M of the knock pin 41 is movable between the first pin hole 421 and the second pin hole 422. The first section pin body 411 moves from the second section pin hole 422 to the first section pin hole 421, and meanwhile, the first end 42A of the side latch pin 42 retracts under the action of elastic force; of course, the side pin 42 moves at this time, and therefore, the first pin 411 moves from the second pin hole 422 to the first pin hole 421 relative to the side pin 42. The second pin body 412 may be positioned within the second pin bore 422 to maintain the first end 42A of the side pin 42 in an extended position. In this manner, extension and retraction of first end 42A of side latch 42 in latch seat 43 is accomplished. The platform 423 is used for receiving the second section pin 412, so that the second section pin 412 can be located in the side latch 42 when the first section pin 411 is located in the first section pin hole 421.
Referring to fig. 6, the side latch device 5 includes a latch 51, a positioning member 52, and a latch holder 53. In the present embodiment, the positioning element 52 is a combination screw.
Referring to fig. 7, the elastic pin 51 may move in the elastic pin holder 53 and the first end 51A of the elastic pin 51 may be extended by an elastic force. The retainer 52 is used to keep the latch 51 in an extended state; that is, the retainer 52 may catch the latch 51. The first end 51A is provided with a guide portion 5a1 for contacting the elastic sheet 301 on the back frame 300. The guide portion 5a1 contacts the resilient piece 301 on the back frame 300 so that the first end 51A of the resilient pin 51 retracts. In the present embodiment, the guide portion 5a1 is a slope.
Referring to fig. 8, in the present embodiment, the back frame 300 is a rectangular frame formed by bending and welding sheet metal. Referring to fig. 2 and 8, during installation, the side of the box body 200 provided with the side latch device 4 is contacted with the elastic sheet 301 on the side of the back frame 300, so that the elastic sheet 301 on the side of the back frame 300 is positioned between the first end portion 42A of the side latch 42 in the extending state and the front surface of the box body 200, that is, the elastic sheet 301 on the side of the back frame 300 is squeezed between the first end portion 42A and the front surface of the box body 200, and the first end portion 42A of the side latch 42 is positioned on the back surface of the elastic sheet 301 on the back frame 300. Then, one side of the box body 200 provided with the side edge spring pin device 5 is contacted with the spring plate 301 on the other side of the back frame 300, and the guide part 5A1 of the first end part 51A of the spring pin 51 in the extending state is contacted with the spring plate 301 on the back frame 300. Due to the pressing of the elastic pieces 301 on the back frame 300, the elastic pin 51 is retracted into the elastic pin base 53 under the guiding action of the guide portion 5a 1. The box 200 is pushed further, and the first end 51A of the elastic pin 51 contacts the elastic sheet 301 of the back frame 300. When the first end 51A of the elastic pin 51 is separated from the elastic sheet 301 on the back frame 300, the first end 51A extends under the action of the elastic force, and the first end 51A is also located on the back surface of the elastic sheet 301 on the back frame 300, so that the elastic sheet 301 on the back frame 300 on the other side is also located between the first end 51A of the elastic pin 51 in the extending state and the front surface of the box body 200. Thus, the installation of the LED display screen is completed.
Referring to fig. 4, in the pre-maintenance of the LED display panel, a tool is inserted into the through hole 30 of the LED module 3 on the front surface of the LED display panel to press the first end 41A of the knock pin 41. Since the first end 41A is elastically contacted with the pin seat 43 and the knock pin 41 is movably inserted into the pin seat 43, the knock pin 41 is pressed and moved in a direction defined by the pin seat 43, so that the second pin body 412 is separated from the second pin hole 422, the first pin body 411 is moved into the second pin hole 422, and the protruding state of the first end 42A of the side pin 42 is released. Since the second end 42B of the side plug 42 is elastically contacted with the plug seat 43, the side plug 42 moves along the position defined by the plug seat 43 under the action of the elastic force, the first segment pin body 411 moves into the first segment pin hole 421, and the first end 42A of the side plug 42 also retracts into the plug seat 43. At this time, one side of the case 200 is released from the contact with the elastic piece 301 of one side of the back frame 300, and the other side of the case 200 is also released from the contact with the elastic piece 301 of the other side of the back frame 300 by pulling the one side of the case 200 forward. Thus, the case 200 can be detached from the front of the back frame 300 for maintenance.
According to the above, when the box body 200 is installed, the first end portion 42A of the side latch 42 in the extended state is firstly contacted with the elastic sheet 301 on one side of the back frame 300, then the guide portion 5a1 of the first end portion 51A of the elastic pin 51 in the extended state is contacted with the elastic sheet 301 on the other side of the back frame 300, and finally, the side latch 42 and the elastic pin 51 are both located on the back of the elastic sheet 301 on the back frame 300, thereby completing the fixing of the box body 200. When the case 200 is detached, the first end 41A of the knock pin 41 is pressed by inserting a tool into the through hole 30 of the LED module 3. The knock pin 41 moves along the pin holder 43 so that the second pin body 412 leaves the second pin hole 422 and the first pin body 411 moves into the second pin hole 422, thereby retracting the first end 42A of the side pin 42 in the extended state and contacting the striking plate 301 of the back frame 300. Thus, the case 200 is disconnected from the elastic pieces 301 of the back frame 300. The case 200 can be quickly disassembled in front of the LED display screen, and the case 200 can be easily and conveniently mounted.
Because the elastic sheet 301 is elastic, it will deform when being squeezed by the side latch device 4 or the side latch device 5, which is convenient for installing the box body 200. Referring to fig. 8 to 10, the elastic sheet 301 includes a fixing portion 3011 and a deforming portion 3012. The fixing portion 3011 is connected to the back frame 300 such that the deformation portion 3012 is located in the inner ring 300A of the back frame 300 and can be in contact with the side latch means 4 or the side latch means 5.
In other embodiments, one side of the case 200 provided with the side latch means 4 is in direct contact with one side of the back frame 300, and one side of the case 200 provided with the side latch means 5 is in direct contact with the other side of the back frame 300.
Referring to fig. 2, the back of the frame 2 is hollowed out and provided with ribs 21. In this way, the module 3 can be fixed on the frame 2 by glue filling.
Referring to fig. 4, the cross-sectional area of the first segment pin body 411 is smaller than the cross-sectional area of the second segment pin body 412. Thus, if the second pin body 412 is located in the second pin hole 422, the first pin body 411 is also located in the second pin hole 422. Specifically, the first pin 411 and the second pin 412 are cylindrical, and the outer diameter of the first pin 411 is smaller than the outer diameter of the second pin 412.
Referring to fig. 5, the first pin hole 421 and the second pin hole 422 are both through holes. The first pin hole 421 is a U-shaped hole, the second pin hole 422 is a through hole communicating with the first pin hole 421, and the cross section of the first pin hole 421 is a circular part. The length direction of the first section pin hole 421 extends along the axial direction of the side pin 42, and the width of the first section pin hole 421 is smaller than the diameter of the cross section of the second section pin hole 422. Such an arrangement facilitates processing. The outer diameter of the first pin body 411 is smaller than the width of the first pin hole 421 so that the first pin body 411 can move from the second pin hole 422 into the first pin hole 421.
Referring to fig. 7, the elastic pin 51 includes a first segment elastic pin body 511 and a second segment elastic pin body 512; specifically, the first section of the spring pin body 511 and the second section of the spring pin body 512 are both cylinders, and the outer diameter of the first section of the spring pin body 511 is larger than that of the second section of the spring pin body 512. The first segment of the latch body 511 is provided with a long waist hole 510. The retainer 52 is mounted in the latch holder 53 with a portion exposed. An exposed portion of the retainer 52 is positioned in the long waist hole 510 so as to maintain the elastic pin 51 in an extended state and prevent the elastic pin 51 from being released. The positioning member 52 is slidable in the long waist hole 510 to the left and right with respect to the elastic pin 51.
Referring to fig. 5, the aforementioned guide portion 5a1 is provided at the end of the first stage latch body 511. The second section of elastic pin body 512 is elastically connected with the elastic pin base 53; specifically, the second segment spring body 512 is connected to the spring pin seat 53 via a spring. When the guide portion 5a1 is pressed, the latch 51 compresses the elastic member, thereby effecting retraction of the latch 51.
Referring to fig. 4, the first end portion 41A of the knock pin 41 includes a first elastic member 41A1, a first flap 41A2, and a first fastener 41A 3. In the present embodiment, the first elastic member 41a1 is a spring. The first end portion 41A of the knock pin 41 is elastically contacted with the latch base 43 by the first elastic member 41A 1. The first fastener 41A3 detachably fixes the first flap 41A2 to the tip of the knock pin 41 so that the first elastic piece 41A1 is located between the latch base 43 and the first flap 41A2, achieving elastic contact of the first end portion 41A with the latch base 43. The size of the outer contour of the first catch 41A2 is larger than the size of the hole in the pin seat 43 for placing the top pin 41, so that when the top pin 41 moves in the direction defined by the pin seat 43, the first catch 41A2 prevents the first end 41A of the top pin 41 from passing through the inside of the pin seat 43, thereby achieving the function of limiting the position. The knock pin 41 can be removed from the latch base 43 by removing the first flap 41a 2.
Referring to fig. 4, the second end 42B of the side latch 42 includes a second resilient member 42B1, a second catch 42B2, and a second fastener 42B 3. In this embodiment, the second elastic member 42B1 is also a spring. The second end 42B of the side latch 42 is elastically contacted with the latch base 43 by the second elastic member 42B 1. The second fastener 42B3 detachably secures the second catch 42B2 to the end of the side latch 42 such that the second resilient member 42B1 is positioned between the latch seat 43 and the second catch 42B2 to provide resilient contact of the second end 42B with the latch seat 43. The outer dimension of the second stopping piece 42B2 is larger than the dimension of the hole in the pin seat 43 for placing the side pin 42, so that when the side pin 42 moves in the direction defined by the pin seat 43, the second stopping piece 42B2 prevents the second end 42B of the side pin 42 from passing through the inside of the pin seat 42, thereby serving as a limit. The side latch 42 can be removed from the latch base 43 by removing the second flap 42B 2.
In the present embodiment, the front surface of the LED module 3 is a plane. Referring to fig. 4 and 7, the top pin 41 is axially perpendicular to the front surface of the LED module 3, the side pin 42 is axially parallel to the front surface of the LED module 3, and the elastic pin 51 is axially parallel to the front surface of the LED module 3. Thus, the processing and installation are convenient. In other embodiments, the axial direction of the top pin 41 is at other angles with respect to the front surface of the LED module 3, the axial direction of the side pin 42 intersects with the front surface of the LED module 3, and the axial direction of the elastic pin 51 intersects with the front surface of the LED module 3.
Referring to fig. 2, the cabinet 200 further includes a support 6 provided at a lower portion of the frame 2. The support 6 is used to support the case 200 together with the bottom of the frame 2, ensuring stability. The support member 6 is rotatable to an operative condition for supporting.
In other implementations, the guide portion 5a1 may also be a cambered or spherical surface.
