Description

Technical Field

[0001] This utility model relates to the field of assembly model technology, and in particular to an assembly model that uses gear transmission to specify the direction. Background Technology

[0002] A gear transmission model is an ingenious mechanical device that uses gears of different sizes, shapes, and numbers of teeth to mesh together, achieving the functions of power transmission, speed variation, and torque conversion. In this model, one or more sets of gears are arranged in a specific pattern. When the driving gear rotates, its power is transmitted to the driven gear through the close contact between the teeth, thus achieving continuous and smooth transmission. This model demonstrates the basic principles of gear transmission, such as the influence of gear ratios on speed and torque, and how complex transmission effects can be achieved through the arrangement and combination of gears. By observing the meshing process of the gears, one can intuitively understand its working principle and appreciate the charm and precision of mechanical transmission.

[0003] Most existing gear transmission models are integrated units, which cannot be quickly adjusted in shape or assembly according to different teaching content. This results in poor overall practicality and fails to meet diverse teaching needs. Therefore, this application provides an assembly model that relies on gear transmission in a specified direction to meet these requirements. Utility Model Content

[0004] The technical problem this invention aims to solve is to provide an assembly model that relies on gear transmission to specify the direction. This addresses the issue that most existing gear transmission models are integrated, making it impossible to quickly adjust the shape of the model and the assembly of different gears according to different teaching content. Consequently, the overall practicality of the device is poor, and it cannot adequately meet the diverse teaching needs.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] An assembly model that uses gear transmission to specify a direction includes a mounting plate. A mounting hole is formed at the top of the mounting plate, and a connecting post is inserted into the mounting hole. A gear model is rotatably mounted on the connecting post. A connecting plate is symmetrically protruding from one end of the mounting plate, and a first connecting groove is symmetrically formed at the other end of the mounting plate. A second connecting groove is formed at the top of the mounting plate. The first and second connecting grooves are internally connected. A positioning hole is formed on the inner side of the first connecting groove. A positioning cavity is formed inside the mounting plate corresponding to one end of the connecting plate. A positioning component is installed in the positioning cavity, and the positioning component is inserted into the positioning hole.

[0007] Optionally, the positioning component includes a positioning block slidably disposed in the positioning cavity, the positioning block being inserted into the positioning hole, an ejection spring for assisting the positioning block to be pushed is installed in the positioning cavity, a sliding groove is provided on the outer side of the mounting plate, a sliding column is slidably disposed in the sliding groove, and a first connecting strip is fixedly connected between the sliding column and the positioning block.

[0008] Optionally, a crossbar is fixed inside the sliding groove, and the sliding column is installed through the crossbar.

[0009] Optionally, the mounting hole has a cross-shaped cross section, the bottom of the plug protrudes to form a plug connector, and the plug connector of the plug is engaged with the mounting hole.

[0010] Optionally, positioning holes are provided on all four sides of the mounting hole, and a fixing cavity is provided inside the plug post. A fixing component that cooperates with the positioning holes for positioning is installed in the fixing cavity.

[0011] Optionally, the fixing assembly includes fixing pins symmetrically slidably disposed in the fixing cavity, an ejector spring for assisting the fixing pins to push is installed in the fixing cavity, the four fixing pins are connected by a second connecting strip, a slide rod is slidably disposed on the insertion post, the bottom of the slide rod is abutted at the center of the second connecting strip, and the top of the slide rod extends out of the insertion post.

[0012] Optionally, a protruding disc is fixed at the top of the plug post, and the top of the slide rod extends through the top of the protruding disc.

[0013] Optionally, a directional arrow is embedded at the top of the gear model, and both ends of the directional arrow are provided with arrowheads.

[0014] Optionally, the gear model has a through hole for the insertion post to pass through, and a ball bearing for auxiliary rolling is embedded in the through hole.

[0015] Optionally, the mounting plate has symmetrically protruding fixing ears on both sides, and the fixing ears have through holes.

[0016] Compared with the prior art, this utility model has at least the following beneficial effects:

[0017] In the above scheme, by the cooperation between the plug plate set on the mounting plate and the first plug slot and the second plug slot, the mounting plate can be positioned and plugged into different positions during operation, thereby forming different shapes. This facilitates the transmission and cooperation of different types of gear models (spur gears, helical gears, bevel gears). The shape of the model and the assembly of different gears can be quickly adjusted according to different teaching content, thereby improving the overall practicality of the device.

[0018] By cooperating with the positioning block and the positioning hole, the sliding column is pulled, which in turn pulls the first connecting belt. As the first connecting belt is pulled, the positioning block is pulled, and as the positioning block is pulled, the push-out spring is compressed. At this time, the plug-in plate is inserted into the first plug-in slot. The sliding column is released, and under the action of the compressed push-out spring, the positioning block is pushed into the positioning hole. This can quickly position and fasten the two mounting plates according to different work requirements, improving the working efficiency between the two mounting plates.

[0019] By setting the fixing components on the gear model and the matching between the mounting holes and positioning sockets, the plug at the bottom of the plug post is inserted into the mounting hole. Pressing down the slide bar pushes the second connecting belt, causing it to move as a whole. During the movement of the second connecting belt, the fixing pin is pulled, thus compressing the ejector spring. At this time, the plug at the bottom of the plug post is stably inserted and fixed into the mounting hole. Releasing the slide bar, the compressed ejector spring pushes the fixing pin into the positioning socket. This allows for quick disassembly and replacement of the gear model before work, depending on the different work requirements. Attached Figure Description

[0034] like Figures 1 to 5 As shown, an embodiment of this utility model provides an assembly model that relies on gear transmission to specify a direction. It includes a mounting plate 1, with symmetrically protruding fixing ears 11 on both sides of the mounting plate 1. The fixing ears 11 can fix the mounting plate 1 in the corresponding position during operation. A receiving hole is provided through the fixing ear 11. A mounting hole 2 is provided at the top of the mounting plate 1. A plug-in post 13 is inserted into the mounting hole 2. A gear model 12 is rotatably mounted on the plug-in post 13.

A second plug-in groove 5 is provided at the top of the mounting plate 1. The first plug-in groove 4 and the second plug-in groove 5 are internally connected. Through the cooperation between the plug-in plate 3 and the first plug-in groove 4 and the second plug-in groove 5 on the mounting plate 1, the mounting plate 1 can be positioned and plugged into different positions during operation, thereby forming different shapes. This facilitates the transmission and cooperation of different types of gear models 12, such as spur gears, helical gears, and bevel gears. The shape of the model and the assembly of different gears can be quickly adjusted according to different teaching content, thereby improving the overall practicality of the device.

[0036] A positioning hole 41 is provided on the inner side of the first insertion slot 4. A positioning cavity is provided inside the mounting plate 1 corresponding to one end of the insertion plate 3. A positioning component 6 is installed in the positioning cavity. The positioning component 6 is inserted into the positioning hole 41. The positioning component 6 includes a positioning block 7 slidably disposed in the positioning cavity. The positioning block 7 is inserted into the positioning hole 41. An ejection spring 8 is installed in the positioning cavity to assist the positioning block 7 in pushing. A sliding groove 101 is provided on the outer side of the mounting plate 1. A sliding post 10 is slidably disposed in the sliding groove 101. A first connecting strip 9 is fixedly connected between the sliding post 10 and the positioning block 7. The cooperation between the positioning block 7 and the positioning hole 41 pulls the sliding column 10. During the pulling of the sliding column 10, the first connecting belt 9 is pulled. During the pulling of the first connecting belt 9, the positioning block 7 is pulled. During the pulling of the positioning block 7, the push-out spring 8 is compressed. At this time, the plug-in plate 3 is inserted into the first plug-in slot 4. The sliding column 10 is released. Under the action of the compressed push-out spring 8, the positioning block 7 is pushed into the positioning hole 41. It can quickly position and fasten the two mounting plates 1 according to different work requirements, improving the working efficiency between the two mounting plates 1.

[0037] A crossbar is fixed inside the sliding groove 101, and the sliding column 10 is installed through the crossbar. The crossbar ensures that the sliding column 10 can be fixed in the sliding groove 101.

[0038] like Figure 1 , Figure 2 and Figure 5As shown, the cross-section of the mounting hole 2 is cross-shaped. The bottom of the plug-in post 13 protrudes to form a plug connector. The plug connector of the plug-in post 13 is inserted into the mounting hole 2. Positioning holes 21 are provided on all four sides of the mounting hole 2. A fixing cavity is provided inside the plug-in post 13. A fixing component 14 is installed in the fixing cavity to cooperate with the positioning holes 21 for positioning. The fixing component 14 includes fixing pins 18 symmetrically slidably disposed in the fixing cavity. An ejector spring 17 is installed in the fixing cavity to assist the fixing pins 18 in pushing. The four fixing pins 18 are connected by a second connecting band 16. A sliding rod 15 is slidably disposed on the plug-in post 13. The bottom of the sliding rod 15 is abutted at the center of the second connecting band 16. The top of the sliding rod 15 extends out of the plug-in post 13. A protruding disc 131 is fixed at the top of the plug-in post 13. The top of the sliding rod 15 extends out through the top of the protruding disc 131.

[0039] By setting the fixing component 14 on the gear model 12 and the cooperation between the mounting hole 2 and the positioning socket 21, the plug at the bottom of the plug post 13 is inserted into the mounting hole 2. Pressing down the slide bar 15 pushes the second connecting belt 16, causing the second connecting belt 16 to move as a whole. During the movement of the second connecting belt 16, the fixing pin 18 is pulled, thus compressing the ejector spring 17. At this time, the plug at the bottom of the plug post 13 is stably inserted and fixed into the mounting hole 2. Releasing the slide bar 15, the fixed pin 18 is pushed into the positioning socket 21 by the compressed ejector spring 17. Before work, the gear model 12 can be quickly disassembled and replaced according to different work requirements.

[0040] The working principle of the technical solution provided by this utility model is as follows:

[0041] When two mounting plates 1 need to be installed horizontally, pull the sliding column 10. During the pulling of the sliding column 10, the first connecting band 9 is pulled. During the pulling of the first connecting band 9, the positioning block 7 is pulled. During the pulling of the positioning block 7, the push-out spring 8 is compressed. At this time, the plug-in plate 3 is inserted into the first plug-in slot 4. Release the sliding column 10. Under the action of the compressed push-out spring 8, the positioning block 7 is pushed into the positioning hole 41, thereby completing the horizontal positioning and fastening of the two mounting plates 1. When it is necessary to fix the mounting plates 1 vertically to each other, the plug-in plate 3 is inserted into the second plug-in slot 5.

[0042] When the gear model 12 needs to be installed, the connector at the bottom of the plug post 13 is inserted into the mounting hole 2. The slide rod 15 is pressed down. During the pressing process, the slide rod 15 drives the second connecting belt 16 to be pushed, thereby moving the second connecting belt 16 as a whole. During the movement of the second connecting belt 16, the fixing pin 18 is pulled, thereby compressing the ejector spring 17. At this time, the connector at the bottom of the plug post 13 is stably inserted and fixed into the mounting hole 2. The slide rod 15 is released, and under the action of the compressed ejector spring 17, the fixing pin 18 is pushed to be inserted into the positioning socket 21, thereby completing the overall positioning and fastening of the gear model 12.

[0043] When it is necessary to determine the direction of transmission for teaching, rotate a gear model 12. Through the meshing transmission between gear models 12 and the pointing arrows 121 set on the gear models 12, the overall rotation sequence of the pointing arrows 121 can be intuitively understood during rotation. Through the arrangement and connection of gear models 12, it is ensured that the model transmits in the predetermined direction, and the types of gears such as spur gears, helical gears, the relationship between the number of teeth and the transmission ratio, and how to achieve rotation in a specific direction through gear combinations can be understood.

Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0045] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
