Description

Technical Field

[0001] This utility model relates to the technical field of advertising gates, and in particular to a quick assembly structure for an advertising gate motor. Background Technology

[0002] As the connecting hub between the core components of a motor and its application scenarios, the early motor assembly structure was oriented towards meeting basic functions. It used basic structures such as bolt fastening and component alignment to fix the various components of the motor and achieve power output. Assembly was completed by manual operation, which was suitable for application scenarios that were mainly focused on single industrial power needs at that time. As the application scenarios of motors continued to expand, their assembly structure design gradually upgraded to refinement and specialization, providing basic support for the popularization of motors in traditional equipment such as machine tools and water pumps. Therefore, a rapid assembly structure for advertising gate motors is particularly needed.

[0003] However, existing motor assembly structures rely heavily on manual step-by-step operations during assembly, requiring the alignment of components and tightening of bolts one by one. They lack rapid positioning and pre-fixing structures, resulting in poor adaptability to automated production lines. Furthermore, subsequent maintenance requires the removal of numerous peripheral parts, and some interference fit or non-standard connection structures are difficult to disassemble without damage, which can easily damage non-vulnerable parts, increase maintenance costs, and affect motor assembly efficiency.

[0004] To address the aforementioned issues, a search revealed a patent with publication number CN218888255U that discloses a rapid assembly structure for motors in an electronic sand table. The patent states that "the beneficial effects of this utility model are: during assembly, firstly, one end of the motor module is manually inserted into multiple insertion slots of the lower limiting plate; then, the upper limiting plate is placed over the other end of the motor module so that the other end of the motor module abuts against one side of the upper limiting plate; finally, the motor module is connected to the other end of the motor module via a fixing device, thus achieving rapid assembly of the motor module." While the insertion slots of the upper / lower limiting plates, in conjunction with the fixing device, enable rapid assembly and disassembly of the motor module and allow for the simultaneous assembly of multiple motors, improving assembly efficiency in electronic sand table scenarios to some extent, the design does not consider the stress stability of the transmission components. The motor module is only limited by the insertion slots and both ends of the fixing device, making it prone to loosening of the fixing device threads due to vibration during high-frequency operation. Furthermore, the structure has limited adaptability, as the insertion slots are bound to the shape of the motor module, requiring replacement of the limiting plate when changing models.

[0005] In light of this, in-depth research into the aforementioned issues led to the creation of this case. Summary of the Invention

[0006] The purpose of this utility model is to provide a quick assembly structure for advertising gate motors, in order to solve the problems mentioned in the background art regarding the existing motor assembly structures. During use, the motor assembly structure relies heavily on manual step-by-step operations, requiring the alignment of components and bolt tightening to be completed one by one. It lacks a quick positioning and pre-fixing structure, has poor adaptability to automated production lines, and requires the removal of a large number of peripheral parts for later maintenance. Some interference fit or non-standard connection structures are difficult to disassemble without damage, which can easily damage non-vulnerable parts, increase maintenance costs, and affect the efficiency of motor assembly.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a quick assembly structure for an advertising door motor, comprising an advertising door, a door frame on one side of the advertising door, a fixing block fixedly connected to one side of the inner wall surface of the door frame, a motor base slidably connected to the inner wall surface of the fixing block, a first connecting block fixedly connected to one side of the surface of the motor base, a positioning pin fixedly connected to one side of the first connecting block, a second connecting block fixedly connected to the other side of the surface of the motor base, an elastic buckle fixedly connected to one side of the second connecting block, a locking block fitted at one end of the elastic buckle, a hand-tightening bolt threadedly connected to one side of the locking block, a threaded rod threadedly connected to one end of the fixing block, and a cover movably sleeved on one side of the surface of the threaded rod.

[0008] Preferably, a first sliding groove is provided on one side of the fixing block, and a second sliding groove is provided on the other side of the fixing block.

[0009] Preferably, one side of the inner wall surface of the fixing block is provided with a concave structure that matches the size of the positioning pin.

[0010] Preferably, the hand-tightened bolt is engaged with the elastic buckle.

[0011] Preferably, the fixing block and the card block are fixedly connected.

[0012] Preferably, the first connecting block is slidably connected to the first sliding groove.

[0013] Preferably, the elastic buckle is slidably connected to the second sliding groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: The quick assembly structure of this advertising gate motor, through the directional guiding structure of "positioning pin + sliding groove", combined with the pre-fixation of elastic buckle and the locking of hand-tightening bolt, eliminates the cumbersome process of traditional step-by-step alignment and multi-bolt tightening, realizing a quick three-step assembly of "push-lock-tighten" without the need for special tools. It meets the convenience requirements of on-site installation of advertising gates. The limiting cooperation of elastic buckle and sliding groove can disperse the vibration load during motor operation. The adjustable tightening design of hand-tightening bolt can adapt to the stability requirements under different working conditions. Moreover, disassembly can be achieved without damage by simply reversing the operation, which greatly improves the assembly efficiency of advertising gate motor. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5This utility model provides a technical solution: a quick assembly structure for an advertising door motor, including an advertising door 1, a door frame 2 on one side of the advertising door 1, a fixing block 3 fixedly connected to one side of the inner wall surface of the door frame 2, a motor base 4 slidably connected to the inner wall surface of the fixing block 3, a first connecting block 5 fixedly connected to one side of the surface of the motor base 4, a positioning pin 6 fixedly connected to one side of the first connecting block 5, a second connecting block 7 fixedly connected to the other side of the surface of the motor base 4, an elastic buckle 8 fixedly connected to one side of the second connecting block 7, a locking block 9 fitted to one end of the elastic buckle 8, a hand-tightening bolt 10 threadedly connected to one side of the locking block 9, a threaded rod 13 threadedly connected to one end of the fixing block 3, and a cover 14 movably sleeved on one side of the surface of the threaded rod 13. In use, the first connecting block 5 on one side of the motor base 4 can be aligned with the first sliding groove 11 of the fixing block 3, while the second connecting block 7 on the other side is aligned with the second sliding groove 12, and the motor base 4 can be pushed horizontally into the inner wall of the fixing block 3 by holding it with both hands. During the sliding process, the first sliding groove 11 restricts the offset of the first connecting block 5, and the second sliding groove 12 guides the elastic buckle 8 to move in a specific direction, preventing misalignment of components during assembly. When the motor base 4 is pushed forward to the end of the first connecting block 5 and fits against the bottom of the first sliding groove 11, the positioning pin 6 will naturally align with the concave structure of the inner wall of the fixing block 3. Gently push the motor base 4 to make the positioning pin 6 embed into the concave structure. At this time, the horizontal position of the motor base 4 is completely limited. Continue to push the motor base 4 so that the second connecting block 7 drives the elastic buckle 8 to extend along the second sliding groove 12. When the front end of the elastic buckle 8 contacts the locking block 9, press the motor base 4 with a little force. The elastic buckle 8 will deform slightly due to the force, and its end will slide smoothly past the locking block 9 and automatically spring back, forming a fitting connection with the locking block 9. A "click" sound can be heard. At this point, the engagement of the elastic buckle 8 and the locking block 9 fixes the motor base 4 vertically. The double limiting effect of the positioning pin 6 and the concave structure, the sliding groove and the connecting block prevents the motor base 4 from shaking. Pick up the hand-tightening bolt 10, align it with the threaded hole on the locking block 9 and turn it clockwise until the end of the bolt is tightly fitted with the surface of the elastic buckle 8. At this point, the elastic buckle 8 is pressed against the inside of the locking block 9 by the hand-tightening bolt 10, eliminating the engagement gap and preventing the buckle from loosening due to vibration during motor operation. The entire process does not require a wrench and can be completed by hand force. Finally, seal and protect the device. Push the cover 14 against the end face of the fixing block 3 until the end of the threaded rod 13 contacts the surface of the motor base 4. Then, take the threaded rod 13 and screw it into the threaded hole at one end of the fixing block 3, so that the cover 14 is in tight contact with the edge of the fixing block 3. The cover 14 can prevent external dust from entering the sliding groove and the gap of the motor base, while covering the assembly parts to improve the aesthetics. The entire assembly process only requires three actions: pushing, pressing and twisting. No special tools are needed throughout the process, and it can be completed by one person in less than 1 minute. Moreover, the cooperation between the positioning pin and the concave structure can ensure the consistency of the motor installation position, laying the foundation for the coaxiality calibration of the output end and the door driven wheel in the future.

[0023] Furthermore, a first sliding groove 11 is provided on one side of the fixing block 3, and a second sliding groove 12 is provided on the other side of the fixing block 3. During use, the two sliding grooves provide directional sliding paths for the first connecting block 5 and the second connecting block 7, respectively, to prevent the motor base 4 from shifting left or right or tilting during assembly. At the same time, the cooperation between the sliding groove and the connecting block can share the vibration load during motor operation, reduce the force on the positioning pin 6 and the elastic buckle 8, and extend the service life of the core positioning components.

[0024] Furthermore, one side of the inner wall surface of the fixing block 3 is provided with a concave structure that matches the size of the positioning pin 6. Through the setting of the fixing block 3 and the positioning pin 6, precise positioning can be achieved when the motor base 4 is pushed into place. After the positioning pin 6 is embedded in the concave structure, it can limit the displacement of the motor base 4 in the horizontal direction, ensuring that the initial installation position of the motor output shaft and the door driven wheel is consistent, providing a basis for subsequent coaxiality calibration and avoiding transmission jamming due to motor position deviation.

[0025] Furthermore, the hand-tightening bolt 10 is engaged with the elastic buckle 8. By using the tightening force of the bolt, the engagement gap between the elastic buckle 8 and the locking block 9 can be eliminated. When the motor vibrates during high-frequency start-stop, it can prevent the elastic buckle 8 from loosening or disengaging due to shaking. At the same time, the adjustable engagement force can adapt to the fastening requirements under different working conditions.

[0026] Furthermore, the fixing block 3 and the locking block 9 are fixedly connected. Through the setting of the fixing block 3 and the locking block 9, the engaging force of the elastic buckle 8 can be transferred to the fixing block 3, preventing the locking block 9 from becoming loose due to force and causing buckle failure. At the same time, the fixed connection structure can ensure the relative position stability of the locking block 9 and the inner concave structure of the positioning pin, ensuring that the buckle engaging position is consistent during each assembly and improving assembly consistency.

[0027] Furthermore, the first connecting block 5 is slidably connected to the first sliding groove 11. The setting of the first connecting block 5 and the first sliding groove 11 can guide the motor base 4 to advance in a straight line, reducing the difficulty of alignment during assembly, and can also bear part of the radial load when the motor is running, avoiding excessive force on the positioning pin 6 alone, which would cause deformation and improve the load-bearing stability of the overall structure.

[0028] Furthermore, the elastic buckle 8 is slidably connected to the second sliding groove 12. The arrangement of the elastic buckle 8 and the second sliding groove 12 guides the elastic buckle 8 to precisely align with the locking block 9 during assembly, preventing "jamming" or "misalignment" due to buckle misalignment. Simultaneously, the sliding groove restricts the offset direction of the elastic buckle 8 under stress deformation, ensuring uniform contact area when the buckle and locking block 9 are engaged, reducing localized wear, and extending the buckle's service life.

[0029] Working principle: During use, the first connecting block 5 on one side of the motor base 4 is aligned with the first sliding groove 11 of the fixing block 3, and the second connecting block 7 on the other side is aligned with the second sliding groove 12. The motor base 4 is then held with both hands and pushed horizontally into the inner wall of the fixing block 3. During sliding, the first sliding groove 11 restricts the offset of the first connecting block 5, and the second sliding groove 12 guides the elastic buckle 8 to move in a specific direction, preventing misalignment of components during assembly. When the motor base 4 is pushed forward until the end of the first connecting block 5 is in contact with the bottom of the first sliding groove 11, the positioning pin 6 will naturally align with the concave structure of the inner wall of the fixing block 3. A gentle push on the motor base 4 causes the positioning pin 6 to embed into the concave structure. At this point, the horizontal position of the motor base 4 is completely defined. Continuing to push the motor base 4 causes the second connecting block 7 to drive the elastic buckle 8 to extend along the second sliding groove 12. When the front end of the elastic buckle 8 contacts the locking block 9, press the motor base 4 with a little force. The elastic buckle 8 will deform slightly due to the force, and its end will slide smoothly past the locking block 9 and automatically spring back, forming a locking connection with the locking block 9, which can be heard with a "click". At this time, the cooperation between the elastic buckle 8 and the locking block 9 fixes the motor base 4 in the vertical direction. The double limiting of the positioning pin 6 and the concave structure, the sliding groove and the connecting block prevents the motor base 4 from shaking. Pick up the hand-tightening bolt 10, align it with the threaded hole on the locking block 9 and turn it clockwise until the end of the bolt is tightly fitted with the surface of the elastic buckle 8. At this time, the elastic buckle 8 is pressed tightly against the inside of the locking block 9 by the hand-tightening bolt 10, eliminating the locking gap and preventing the buckle from loosening due to vibration during motor operation. The whole process does not require a wrench and can be completed by hand force. Finally, a sealing protection is applied. Push the cover 14 to fit against the end face of the fixing block 3 until the end of the threaded rod 13 contacts the surface of the motor base 4. Then, screw the threaded rod 13 into the threaded hole at one end of the fixing block 3 to make the cover 14 and the edge of the fixing block 3 in tight contact. The cover 14 can prevent external dust from entering the sliding groove and the gap of the motor base, while covering the assembly part to improve the aesthetics. The entire assembly process only requires three actions: pushing, pressing, and twisting. No special tools are required, and it can be completed by one person in less than 1 minute. Moreover, the cooperation between the positioning pin and the concave structure can ensure the consistency of the motor installation position, laying the foundation for the coaxiality calibration of the output end and the door driven wheel in the later stage, which greatly improves the assembly efficiency of the advertising door motor.
