Description

Technical Field

[0001] This utility model relates to the field of aviation model technology, and in particular to an aircraft model. Background Technology

[0002] Airplane models are often used as tools to popularize aviation knowledge and cultivate aviation science and technology talents. With the development of society, airplane models have gradually entered the toy field, making their use more accessible to the general public.

[0003] In related technologies, the aircraft model includes a fuselage and wings located on both sides of the fuselage, and the fuselage and wings are connected by threaded fasteners.

[0004] However, for some more realistic aircraft models, the overall size and weight are larger. During the disassembly of the fuselage and wings, it is often necessary for one worker to support the wings while another worker disassembles the threaded connections between the fuselage and wings. The disassembly of the fuselage and wings in the aircraft model requires the assistance of multiple workers, and the disassembly and assembly operations between the fuselage and wings are extremely inconvenient. Utility Model Content

The fuselage has mounting holes with through holes on the walls of the mounting holes, and a locking structure is also provided on the fuselage. The wings are provided with mounting protrusions, which are slidably inserted into the mounting holes. A first connecting structure is provided on the mounting protrusions. The locking module includes an elastic connector and a locking member. The locking member has a second connecting structure for detachable connection with the first connecting structure. The locking member is slidably disposed in the through holes and has a locked state and a loosened state. The elastic connector is connected to the locking member and the fuselage respectively and is used to provide elastic force to switch the locking member from the loosened state to the locked state. When the locking member is in the locked state, the first connecting structure is connected to the second connecting structure.

Since the fuselage is provided with a locking structure, when the locking component is in the loose state, the locking structure can connect with the locking component to prevent the locking component from automatically switching from the loose state back to the locked state under the elastic force of the elastic connector. At this time, the operator can grab the wings with both hands and smoothly pull the mounting protrusions on the wings out of the mounting holes, thereby realizing the disassembly between the wings and the fuselage. Thus, a single operator can complete the disassembly between the fuselage and the wings, reducing the difficulty of disassembling the fuselage and wings in the aircraft module.

[0012] According to the aircraft model described in this embodiment of the present invention, the locking part has an abutting slope at one end near the mounting hole opening, and the mounting protrusion can push the locking part back into the insertion hole through the abutting slope.

[0013] According to the aircraft model described in the embodiment of this utility model, the wall of the through hole is provided with a guide groove, which extends along the axial direction of the through hole.

[0036] The following is for reference. Figures 1 to 8 The aircraft model described in this application is described in detail.

[0037] It should be noted that the aircraft model includes a fuselage 10 and wings 20. There are two wings 20, which are located on the left and right sides of the fuselage 10 respectively. The following description mainly uses the fuselage 10 and the left wing 20 as examples to illustrate the aircraft model of this application.

[0038] refer to Figures 1 to 8 According to an embodiment of the present invention, an aircraft model includes a fuselage 10, a wing 20, and a locking module 100. The fuselage 10 has a mounting hole 211, and the wall of the mounting hole 211 has an insertion hole 221. The fuselage 10 also has a locking structure. The wing 20 is disposed on a mounting protrusion 21, which is slidably disposed within the mounting hole 211. The mounting protrusion 21 has a first connecting structure. The locking module 100 includes an elastic connector 110 and a locking member 120. The locking member 120 has a second connecting structure for detachably connecting with the first connecting structure. The locking member 120 is slidably disposed on the... Within the insertion hole 221, the locking member 120 has a locked state and a loosened state. The elastic connector 110 is connected to the locking member 120 and the body 10 respectively, and is used to provide the elastic force that switches the locking member 120 from the loosened state to the locked state. When the locking member 120 is in the locked state, the first connecting structure is connected to the second connecting structure. When the locking member 120 is in the loosened state, the first connecting structure is separated from the second connecting structure, and the locking structure is connected to the locking member 120 to prevent the locking member 120 from automatically switching from the loosened state to the locked state under the elastic force of the elastic connector 110.

[0039] For example, such as Figures 1 to 8 As shown, the aircraft model includes a fuselage 10, wings 20, and a locking module 100. The left end of the fuselage 10 has a mounting hole 211 extending laterally, and the wall of the mounting hole 211 has a through hole 221 extending longitudinally. The fuselage 10 also has a locking structure. The right end of the wing 20 has a mounting protrusion 21 extending laterally, and the mounting protrusion 21 has a first connecting structure. The locking module 100 includes an elastic connector 110 and a locking member 120. The locking member 120 is slidably disposed within the through hole 221 in the longitudinal direction. The locking member 120 has a second connecting structure at its front end. The elastic connecting member 110 is connected to the locking member 120 and the body 10 respectively, and is used to provide the elastic force to keep the locking member 120 moving forward. When the locking member 120 is in the locked state, the second connecting structure of the locking member 120 is connected to the first connecting structure of the mounting protrusion 21. When the locking member 120 is in the loosened state, the locking member 120 retracts into the insertion hole 221, the first connecting structure is disconnected from the second connecting structure, and the locking structure is connected to the locking member 120.

[0040] Furthermore, during the installation of the wing 20 and the fuselage 10, the operator can insert the mounting protrusion 21 into the mounting hole 211. At this time, under the elastic force of the elastic connector 110, the locking member 120 moves forward, so that the second connecting structure on the locking member 120 approaches and connects with the first connecting structure on the mounting protrusion 21. At this time, the locking member 120 can lock and fix the mounting protrusion 21, preventing the mounting protrusion 21 from disengaging from the mounting hole 211, thereby realizing the connection between the wing 20 and the fuselage 10. During the disassembly of the wing 20 and the fuselage 10, the operator can overcome the elastic force of the elastic connector 110. The locking member 120 is driven to move backward so that it retracts into the insertion hole 221. At this time, the first connecting structure and the second connecting structure are separated, and the locking member 120 releases its locking fixation on the mounting protrusion 21. When the locking member 120 moves forward until the locking structure connects with the locking member 120, the locking structure locks the locking member 120 to prevent the locking member 120 from automatically moving forward under the elastic force of the elastic connector 110 to lock the mounting protrusion 21 again. At this time, the operator can drive the wing 20 to pull the mounting protrusion 21 out of the mounting hole 211, thereby realizing the disassembly between the wing 20 and the fuselage 10.

[0041] Understandably, the elastic connector 110 is designed so that when the locking member 120 is in the locked state, the locking member 120 can be stably kept in the locked state under the action of the elastic connector 110, thereby reducing the probability that the locking member 120 will automatically release its own locking state, and thus improving the stability of the connection between the fuselage 10 and the wing 20.

[0042] Understandably, the mounting protrusion 21 and mounting hole 211 are designed so that when the locking device 120 switches from the locking state to the loose state, the mounting protrusion 21 can still pass through the mounting hole 211, so that the wing 20 can still be normally connected to the fuselage 10, and the wing 20 will not immediately detach from the fuselage 10 after the locking device 120 switches to the loose state, so that the staff can grab the wing 20 and stably separate the wing 20 from the fuselage 10.

[0043] Understandably, the locking structure allows the locking member 120 to switch from the locked state to the released state under the action of the locking structure. Under this action, the locking member 120 can overcome the elastic force of the elastic connector 110 and remain in the released state. In this case, the operator does not need to apply a pushing force to the locking member 120 all the time, so that the operator can free up his hands to remove the wing 20 from the fuselage 10.

[0044] In some embodiments of this utility model, reference is made to Figure 7 and Figure 8The locking structure is a protrusion 232 on the body 10, and the locking member 120 is provided with a positioning hole 122a that is adapted to the protrusion 232.

[0045] Furthermore, when the operator drives the locking member 120 to switch from the locked state to the loose state, the protrusion 232 on the machine body 10 can be inserted into the positioning hole 122a on the locking member 120. At this time, under the abutment of the protrusion 232, the locking member 120 can balance the elastic force of the elastic connector 110, so that the locking member 120 can remain in the loose state. When the operator needs to switch the locking member 120 from the loose state to the locked state, the operator can drive the locking member 120 to move backward a certain distance so that the protrusion 232 disengages from the positioning hole 122a. At this time, under the elastic force of the elastic connector 110, the locking member 120 can automatically switch to the locked state.

[0046] Understandably, the protrusion 232 and the positioning hole 122a have a simple structure and are easy to manufacture.

[0047] In a further embodiment of the present invention, the wall of the insertion hole 221 is provided with a connecting hole 231 that communicates with the outside. The locking member 120 includes a locking pin 121 and a handle 122 connected to each other. The locking pin 121 is slidably inserted into the insertion hole 221, the handle 122 is inserted into the connecting hole 231 and extends to the outside. The positioning hole 122a is provided on the handle 122, and the protrusion 232 is provided on the wall of the connecting hole 231.

[0048] For example, such as Figures 4 to 8 As shown, the upper wall of the through hole 221 is provided with a vertically extending connecting hole 231. The connecting hole 231 extends upward to the outside of the through hole 221. The locking member 120 includes a locking pin 121 and a handle 122. The locking pin 121 is slidably inserted into the through hole 221 in the front-back direction. The handle 122 is slidably inserted into the connecting hole 231 in the front-back direction and extends upward to the outside. The handle 122 is provided with a positioning hole 122a. The wall of the connecting hole 231 is provided with a protrusion 232.

[0049] Furthermore, by driving the handle 122 to move in the front-to-back direction, the operator can move the entire locking component 120 in the front-to-back direction, so that the locking component 120 can switch between a locked state and a loose state. When the locking component 120 is in the loose state, the protrusion 232 passes through the positioning hole 122a on the handle 122 to lock and fix the locking component 120. When the locking component 120 is in the locked state, the locking pin 121 approaches the mounting protrusion 21 under the elastic force of the elastic connector 110, so that the second connecting structure on the locking pin 121 connects with the first connecting structure on the mounting protrusion 21, thereby achieving the locking and fixing of the mounting protrusion 21.

[0050] Understandably, the handle 122 is designed so that operators can switch the entire locking component 120 between the locked and unlocked states by driving the handle 122.

[0051] In some embodiments of this utility model, protrusions 232 are provided on the two opposite walls of the connecting hole 231, and positioning holes 122a are provided on the handle 122 corresponding to each protrusion 232.

[0052] For example, such as Figure 7 As shown, each of the left and right walls of the connecting hole 231 is provided with a protrusion 232, and each of the left and right ends of the handle 122 is provided with a positioning hole 122a. When the locking member 120 is in a loose state, the two protrusions 232 are respectively inserted into the two positioning holes 122a.

[0053] It is understandable that by setting multiple sets of matching protrusions 232 and positioning holes 122a, the locking member 120 can be more stably kept in the loose state after switching from the locked state to the loose state, so as to reduce the probability that the locking member 120 will automatically switch from the loose state to the locked state under the action of the elastic connector 110.

[0054] In some other embodiments of this utility model, the locking structure can also be a magnetic element. The locking element 120 is provided with a magnetic element for magnetic attraction with the magnetic element. In this case, when the locking structure is in a loose state, the magnetic element and the magnetic element are attracted to each other, so that the locking element 120 can be stably kept in the loose state.

[0055] In some other embodiments of this utility model, the locking structure can also be a suction head. In this case, when the locking structure is in a loose state, the suction head adsorbs the locking member 120 so that the locking member 120 can be stably kept in the loose state.

[0056] In some embodiments of this utility model, the first connecting structure is a locking part 123, and the second connecting structure is a locking hole 21a on the mounting protrusion 21. When the locking member 120 is in the locked state, the locking part 123 is plugged into and pulled into the hole wall of the locking hole 21a.

[0057] For example, such as Figure 3 and Figure 8 As shown, the front end of the locking pin 121 has a locking part 123, and the rear side of the mounting protrusion 21 has a locking hole 21a. When the mounting protrusion 21 passes through the mounting hole 211, the locking hole 21a on the mounting protrusion 21 is aligned with the through hole 221. At this time, under the elastic force of the elastic connector 110, the locking pin 121 can move forward so that the locking part 123 passes through the locking hole 21a, thereby realizing the locking pin 121 to lock and fix the mounting protrusion 21.

[0058] Understandably, the locking part 123 and the locking hole 21a have a simple structure and are easy to manufacture.

[0059] It should be noted that when the mounting protrusion 21 is not inserted into the mounting hole 211, the locking part 123 will extend out of the insertion hole 221 and be inserted into the mounting hole 211 under the elastic force of the elastic connector 110. In this case, the locking part 123 will interfere with the mounting protrusion 21 during the process of the mounting protrusion 21 being inserted into the mounting hole 211.

[0060] Based on the above problems, in a further embodiment of this utility model, referring to Figure 8 The locking part 123 has an abutting slope 123a at one end near the opening of the mounting hole 211. The mounting protrusion 21 can push the locking part 123 back into the insertion hole 221 through the abutting slope 123a.

[0061] Understandably, the setting of the abutting slope 123a allows the mounting protrusion 21 to contact the abutting slope 123a on the locking part 123 during the process of the mounting protrusion 21 passing through the mounting hole 211. The abutting slope 123a pushes the locking part 123 back into the insertion hole 221. At this time, the locking part 123 avoids the mounting protrusion 21, and the mounting protrusion 21 can pass smoothly into the mounting hole 211. After the mounting protrusion 21 is completely passed into the mounting hole 211, the locking hole 21a on the mounting protrusion 21 is aligned with the insertion hole 221. Under the elastic force of the elastic connector 110, the locking part 123 can automatically insert into the locking hole 21a to achieve locking and fixing of the mounting protrusion 21.

[0062] In some other embodiments of this utility model, the first connecting structure and the second connecting structure can both be magnetic components. In this case, when the locking member 120 is in the locked state, the first connecting structure and the second connecting structure can be magnetically attracted to each other to achieve locking and fixing of the locking member 120 to the mounting protrusion 21.

[0063] In some embodiments of this utility model, the wall of the through hole 221 is provided with a guide groove 222, which extends along the axial direction of the through hole 221. The locking member 120 is provided with a guide protrusion 125, which is slidably inserted into the guide groove 222.

[0064] For example, such as Figure 6 and Figure 8 As shown, the insertion hole 221 extends in the front-to-back direction, and the wall of the insertion hole 221 is provided with a guide groove 222 extending in the front-to-back direction. The locking member 120 is provided with a guide protrusion 125, which is slidably inserted in the guide groove 222 in the front-to-back direction.

[0065] It is understandable that by setting the guide groove 222 and the guide protrusion 125, the guide protrusion 125 can move accurately in the front-back direction under the guidance of the groove wall of the guide groove 222, so that the entire locking member 120 can slide accurately in the front-back direction within the insertion hole 221.

[0066] In a further embodiment of this utility model, reference is made to... Figure 6 and Figure 8 The left and right sides of the insertion hole 221 are provided with guide grooves 222 extending forward and backward, and the left and right ends of the locking member 120 are provided with guide protrusions 125. The two guide protrusions 125 are slidably inserted into the two guide grooves 222 respectively.

[0067] It is understandable that by setting two guide grooves 222 and correspondingly setting two guide protrusions 125, the movement of the locking member 120 in the front and back directions is more precise, thereby further reducing the probability of the locking member 120 deviating during the sliding process.

[0068] In some embodiments of this utility model, the elastic connector 110 is a spring, the through hole 221 is provided with a first positioning post 223 on the hole wall opposite to the mounting hole 211, the locking member 120 is provided with a second positioning post 124, and the opposite ends of the spring are respectively sleeved on the first positioning post 223 and the second positioning post 124.

[0069] For example, such as Figure 6 and Figure 8 As shown, the elastic connector 110 is a spring, and the rear wall of the through hole 221 is provided with a first positioning post 223 extending back and forth. The rear end of the locking member 120 is provided with a second positioning post 124 extending back and forth. The rear end of the spring is sleeved on the first positioning post 223, and the front end of the spring is sleeved on the second positioning post 124.

[0070] It is understandable that the arrangement of the first positioning post 223 and the second positioning post 124 enables the spring to deform stably in the front-back direction, so that the spring can stably apply a rearward thrust to the locking member 120.

[0071] Understandably, the spring is more securely installed because its two ends are respectively fitted onto the first positioning post 223 and the second positioning post 124.

[0072] In some embodiments of this utility model, reference is made to Figure 1 , Figure 5 and Figure 6 The body 10 includes a body 300 and a connecting module 200. The connecting module 200 is detachably mounted on the body 300. The mounting hole 211, the insertion hole 221 and the locking structure are all mounted on the connecting module 200.

[0073] Understandably, since the mounting hole 211, the insertion hole 221 and the locking structure are all located on the connecting module 200, and the connecting module 200 and the main body 300 are detachably connected, the connecting module 200 can be manufactured separately and then installed on the main body 300, which reduces the manufacturing difficulty of the entire main body 10.

[0074] In a further embodiment of this utility model, reference is made to... Figure 5 and Figure 6 The connection module 200 includes a connection shell 210, a mounting shell 220, and a cover plate 230. The connection shell 210 is provided with a receiving groove 212 and a mounting hole 211. The mounting hole 211 communicates with the receiving groove 212. The mounting shell 220 is installed in the receiving groove 212. An insertion hole 221 is formed on the mounting shell 220. The cover plate 230 is located at the opening of the receiving groove 212 and is detachably connected to the connection shell 210. A locking structure is provided on the cover plate 230.

[0075] Understandably, when manufacturing the connection module 200, the connection shell 210, the mounting shell 220, and the cover plate 230 can be manufactured separately. Then, the operator can install the mounting shell 220 into the receiving groove 212 and install the cover plate 230 into the slot of the receiving groove 212 to form the entire connection module 200. Since the connection shell 210, the mounting shell 220, and the cover plate 230 can be manufactured independently, the manufacturing difficulty of the entire connection module 200 is reduced.

[0076] In a specific embodiment of this utility model, reference is made to Figures 5 to 7 The connecting hole 231 is provided on the cover plate 230, and the wall of the through hole 221 is provided with an opening that communicates with the connecting hole 231.

[0077] In some embodiments of this utility model, for ease of manufacturing of the mounting shell 220, reference is made. Figure 6 The mounting housing 220 includes a first housing 224 and a second housing 225, which are detachably connected and together define an insertion hole 221.

[0078] In some embodiments of this utility model, in order to improve the connection strength between the fuselage 10 and the wing 20, reference is made to... Figure 1 The fuselage 10 includes two connecting modules 200 distributed front and rear, and each connecting module 200 is equipped with a locking module 100; the wing 20 is provided with two mounting protrusions 21 distributed front and rear.
