Description

Technical Field

[0001] The present invention relates to the technical field of advertising machines, and specifically relates to a connection structure and a connection method for an advertising machine frame. Background Art

[0002] Existing advertising machines generally include an outer frame, an outer housing, and an inner housing. The outer frame, the outer housing, and the inner housing are connected through a connection structure. After retrieval, a patent with the authorization number CN208225464U in China discloses a connection structure for an advertising machine frame, which includes a rectangular outer frame, an inner housing of the advertising machine, an outer housing of the advertising machine, and corner codes. The inner housing of the advertising machine is framed inside the outer housing of the advertising machine. The outer housing of the advertising machine and the inner housing of the advertising machine are detachably connected through fasteners. The outer frame is provided with an inwardly concave annular inner concave card slot, and the inner housing of the advertising machine is snap-fitted with the inner concave card slot. Although the structure is simple, convenient for disassembly and assembly, and has high precision, in order to make the connection between the outer housings of the advertising machine have high tightness, a sealing strip is usually provided at the connection. However, as the use time becomes longer, the sealing strip will be affected by temperature and aging during use, resulting in deformation of the sealing strip. As a result, the sealing strip cannot be closely attached to the housing, and further leads to a decrease in the tightness of the connection structure. Summary of the Invention

[0003] Aiming at the deficiencies of the prior art, the present invention provides a connection structure and a connection method for an advertising machine frame, which solves the problem that in order to make the connection between the existing advertising machine outer shell frames have high tightness, a sealing strip is usually provided at the connection. However, as the use time becomes longer, the sealing strip will be affected by temperature and aging during use, resulting in deformation of the sealing strip. As a result, the sealing strip cannot be closely attached to the housing, and further leads to a decrease in the tightness of the connection structure.

[0004] To achieve the above purposes, the present invention is realized through the following technical solutions: A connection structure and a connection method for an advertising machine frame, including a device main body, a frame, a sealing strip, and a card slot. The card slot is welded inside the device main body. The card slot is snap-fitted with a card block. The card block is welded to the bottom surface of a lifting rod. Circular holes are opened at both ends of the lifting rod, and the inner walls of the circular holes at both ends of the lifting rod are threadedly connected to the outer wall of a threaded rod. A limiting block is welded to one end of the bottom of the threaded rod. One end of the top of the threaded rod is welded to the bottom of a turntable. A knob is welded to the top of the turntable. The turntable is embedded inside a back plate. The back plate is provided with a frame around it. The ends of adjacent frames are in contact with each other. A fixing frame is sleeved outside the frame. The fixing frame is connected to the frame through a fastening bolt. A sealing strip is provided between the frame and the device main body.

[0005] Preferably, the cross-section of the card slot is in a C-shaped structure, and the card slots are distributed on the four end surfaces of the device body. Each card slot corresponds to a card block, and one end of the bottom of the card block is in an arc-shaped convex structure. The engagement of the four card slots and the card blocks is conducive to firmly connecting the four ends of the device body and the four ends of the back plate.

[0006] Preferably, the sealing strip is in a rectangular structure, and the sealing strip is sleeved on the outer side of the top of the device body. A groove is formed on the side surface of the sealing strip, and a support strip is embedded in the groove. The support strip is made of stainless steel. Embedding the support strip on the outer side of the sealing strip is conducive to reducing the deformation of the sealing strip.

[0007] Preferably, both ends of the frame are cut at a 45-degree angle, and the ends of adjacent frames are spliced into a right angle, and the inner side of the right angle is closely attached to the outer side of the back plate, which is conducive to keeping the frame and the back plate sealed around.

[0008] Preferably, two bolts are welded on the inner side of the frame. The cross-section of the bolt is in a rectangular structure. The bolt is inserted into the slot. The slot is opened on the side surface around the back plate. By removing the bolt on one side of the frame from the slot, the frame can be quickly disassembled, repaired and replaced.

[0009] Preferably, the four frames are spliced into a rectangular structure with each other, and the outer side of the rectangular structure formed by the frames is closely attached to the inner side of the fixed frame. Support blocks are welded on the outer side of the fixed frame at equal intervals. The support blocks are in a triangular structure. The fixed frame is conducive to fixing the four frames, thereby improving the overall firmness.

[0010] Preferably, the outer sides around the top of the device body are in a slope shape, and the outer sides around the top of the device body fit with the slope-shaped surface on the inner side of the frame. By continuously fitting the frame and the slope around the top of the device body, a high sealing performance is achieved between the frame and the device body.

[0011] Preferably, the steps are as follows:

[0012] S1: Align and insert the two bolts on the inner side of the frame into the slots on the side surface of the back plate, insert the four side frames in sequence, connect the four frames end to end, make the 45-degree angle cut surfaces at the ends of each frame fit with each other, then sleeve the fixed frame on the outside of the rectangular frame formed by the frames, and insert fastening bolts into the hole slots at the four ends of the fixed frame, so that the bottom of the fastening bolt is threadedly connected to the end of the frame, thereby completing the connection of the frames;

[0013] S2: Embed the support strip into the groove on the outer side of the sealing strip, sleeve the sealing strip on the outer side of the top of the device body, align the outer side of the frame with the outer side of the device body, and press down to make the card block under the back plate engage with the card slot of the device body, thereby completing the connection of the back plate and the device body;

[0014] S3: By rotating the knob at the top of the backplate, the knob can drive the threaded rod to rotate through the turntable. When the threaded rod rotates, it can drive the lifting rod to move upward through the thread on the outer wall. Then the lifting rod will drive the clamping block to move, making the clamping block away from the surface of the device body. While the clamping block is moving, it remains in snap connection with the card slot. Thus, the device body and the backplate are continuously fitted and approached. At the same time, the frame will continuously fit with the slopes around the top of the device body, thereby ensuring the sealing performance inside the device body. While the frame and the device body are continuously fitting with each other, they continuously squeeze the sealing strip, so that the sealing strip can fully fit with the frame and the surface of the device body, thereby further improving the sealing performance inside the device body through the sealing strip, and then completing the connection of the advertising machine frame.

[0015] The present invention provides a connection structure and a connection method for an advertising machine frame. It has the following beneficial effects:

[0016] (1) For the connection structure and the connection method of the advertising machine frame, when the sealing strip of the connection structure deforms after long-term use and there is a gap between it and the housing, by rotating the knob at the top of the backplate, the knob can drive the threaded rod to rotate through the turntable. When the threaded rod rotates, it can drive the lifting rod to move upward through the thread on the outer wall. Then the lifting rod will drive the clamping block to move, making the clamping block away from the surface of the device body. While the clamping block is moving, it remains in snap connection with the card slot. Thus, the device body and the backplate are continuously fitted and approached. At the same time, the frame will continuously fit with the slopes around the top of the device body, thereby ensuring the sealing performance inside the device body. While the frame and the device body are continuously fitting with each other, they continuously squeeze the sealing strip, so that the sealing strip can fully fit with the frame and the surface of the device body, thereby eliminating the gap between the sealing strip and the housing.

[0017] (2) For the connection structure and the connection method of the advertising machine frame, align the outside of the frame with the outside of the device body and press it downward, so that the clamping block below the backplate is engaged with the card slot of the device body, so that the backplate and the device body can be quickly connected. When it is necessary to disassemble the backplate, the backplate can be pulled outwards through the gap between the backplate and the device body, so that the buckle is disengaged from the clamping block, which is beneficial for convenient disassembly.

[0018] Therefore, it solves the problem that in order to make the connection between the frames of the existing advertising machine housing have high sealing performance, a sealing strip is usually set at the connection. However, as the use time becomes longer, the sealing strip will be affected by temperature and aging during use, resulting in deformation of the sealing strip. As a result, the sealing strip cannot be closely attached to the housing, and further the sealing performance of the connection structure decreases. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Embodiment 1:

[0029] Please refer to Figure 1-7, an embodiment of the present invention provides a technical solution: a connection structure of an advertising machine frame, including a device main body 1, a frame 2, a sealing strip 10 and a card slot 13. A card slot 13 is welded inside the device main body 1. The card slot 13 is engaged with a card block 7. The card block 7 is welded to the bottom surface of the lifting rod 6. Circular holes are provided at both ends of the lifting rod 6, and the inner walls of the circular holes at both ends of the lifting rod 6 are threadedly connected to the outer wall of the threaded rod 5. A limiting block 17 is welded to one end of the bottom of the threaded rod 5. One end of the top of the threaded rod 5 is welded to the bottom of the turntable 8. A knob 9 is welded to the top of the turntable 8. The turntable 8 is embedded inside the back plate 12. A frame 2 is provided around the back plate 12. The ends of adjacent frames 2 are in contact with each other. A fixing frame 3 is sleeved outside the frame 2. The fixing frame 3 is connected to the frame 2 by a fastening bolt 4. A sealing strip 10 is provided between the frame 2 and the device main body 1. The sealing strip 10 is in a rectangular structure and is sleeved outside the top of the device main body 1. A groove is provided on the side surface of the sealing strip 10, and a support strip 11 is embedded inside the groove. The support strip 11 is made of stainless steel. When the sealing strip 10 of the connection structure is deformed after long-term use and there is a gap with the housing, by rotating the knob 9 at the top of the back plate 12, the knob 9 can drive the threaded rod 5 to rotate through the turntable 8. When the threaded rod 5 rotates, it can drive the lifting rod 6 to move upward through the thread on the outer wall. Then the lifting rod 6 will drive the card block 7 to move, making the card block 7 away from the surface of the device main body 1. While the card block 7 is moving, it remains engaged with the card slot 13. Then the device main body 1 and the back plate 12 are continuously brought closer and closer. At the same time, the frame 2 will continuously fit with the slopes around the top of the device main body 1, so as to ensure the sealing inside the device main body 1. While the frame 2 and the device main body 1 continuously fit with each other, they continuously squeeze the sealing strip 10, so that the sealing strip 10 can fully fit with the surfaces of the frame 2 and the device main body 1, thus eliminating the gap between the sealing strip 10 and the housing.

[0030] Embodiment 2:

[0031] Both ends of the frame 2 are cut at a 45-degree angle, and the ends of adjacent frames 2 are spliced at a right angle. The inner side of the right angle is closely attached to the outer side of the back panel 12. Two pins 16 are welded inside the frame 2. The cross-section of the pin 16 is rectangular. The pin 16 is inserted into the inside of the slot 15. The slot 15 is opened on the four side surfaces of the back panel 12. The four frames 2 are spliced with each other to form a rectangular structure, and the outer side of the rectangular structure formed by the splicing of the frames 2 is closely attached to the inner side of the fixed frame 3. Support blocks 14 are welded on the outer side of the fixed frame 3 at equal intervals. The support blocks 14 are triangular in structure. The outer sides of the four corners of the top of the device body 1 are sloped, and the outer sides of the four corners of the top of the device body 1 fit with the sloped surface of the inner side of the frame 2. By removing the pin 16 on one side of the frame 2 from the inside of the slot 15, the frame 2 can be quickly disassembled, repaired and replaced. The fixed frame 3 is beneficial to fix the four frames 2, thereby improving the overall firmness. Through the continuous fitting of the frame 22 and the slopes of the four corners of the top of the device body 11, the frame 2 and the device body 1 have a high sealing performance. Align the outer side of the frame 2 with the outer side of the device body 1 and press down to make the latch 7 below the back panel 12 engage with the slot 13 of the device body 1, so that the back panel 12 and the device body 1 can be quickly connected. When the back panel 12 needs to be disassembled, the back panel 12 can be pulled outwards through the gap between the back panel 12 and the device body 1, so that the buckle disengages from the latch 7, which is beneficial to facilitate disassembly.

[0032] Embodiment 3:

[0033] A connection method for an advertising machine frame is as follows:

[0034] S1: Align and insert the two pins 16 inside the frame 2 with the slots 15 on the side of the back panel 12, and insert them into the four side spans in turn. Connect the four frames 2 end to end so that the 45-degree angle cut surfaces at the ends of each frame 2 are mutually attached. Then, put the fixed frame 3 on the outside of the rectangular frame formed by the frames 2, and insert fastening bolts 4 into the four end holes of the fixed frame 3 so that the bottom of the fastening bolts 4 is threadedly connected to the ends of the frames 2, thus completing the connection of the frames 2;

[0035] S2: Install the support strip 11 in the groove on the outer side of the sealing strip 10, and put the sealing strip 10 on the outer side of the top of the device body 1. Align the outer side of the frame 2 with the outer side of the device body 1 and press down to make the latch 7 below the back panel 12 engage with the slot 13 of the device body 1, thus completing the connection of the back panel 12 and the device body 1;

[0036] S3: By rotating the knob 9 at the top of the back plate 12, the knob 9 can drive the threaded rod 5 to rotate through the turntable 8. When the threaded rod 5 rotates, it can drive the lifting rod 6 to move upward through the thread on the outer wall. Then the lifting rod 6 will drive the clamping block 7 to move, making the clamping block 7 away from the surface of the device body 1. While moving, the clamping block 7 remains in snap connection with the clamping groove 13. Thus, the device body 1 and the back plate 12 are continuously fitted and approached. At the same time, the frame 2 will continuously fit with the slopes around the top of the device body 1, so as to ensure the sealing inside the device body 1. While the frame 2 and the device body 1 are continuously fitting with each other, they continuously squeeze the sealing strip 10, so that the sealing strip 10 can fully fit with the surface of the frame 2 and the device body 1, thereby further improving the sealing inside the device body 1 through the sealing strip 10, and then completing the connection of the advertising machine frame.
