Description

Technical Field

[0001] This application relates to the field of luggage technology, and more specifically, to a handle connection structure. Background Technology

[0002] Luggage, as a convenient travel tool, has been widely used. The common structure of a suitcase consists of a main body with handles, which are fixed to the main body during the initial production process. With the emergence of consumer demand for customized luggage, luggage with easily detachable components has become a rising demand in this field. Traditional luggage is assembled as a whole at the time of purchase, which increases transportation costs and storage space requirements. Therefore, how to provide stable and easily detachable handles without affecting the actual user experience has become a problem that needs to be solved. Utility Model Content

[0003] In view of the deficiencies in the prior art, the purpose of this application is to provide a handle connection structure that enables quick disassembly and easy installation of casters without tools.

[0004] According to the handle connection structure provided in this application, the assembly includes a mounting body having at least two mounting holes; a handle assembly including a handle body having a snap-fit ​​end, and further including a pair of mounting seats having a stop portion for limiting the displacement of the handle body, the stop portion having a positioning hole for inserting the snap-fit ​​end, and a mounting portion extending into the mounting hole; a pair of locking seats slidably disposed on the inner wall side of the mounting body, and slidably connected to the mounting seats through a first guide member and a second guide member that cooperate with each other; a switch disposed on the locking seats; when the locking seats slide along the mounting seats to the locking position, operating the switch can fix the locking seats and the mounting seats relative to each other, thereby realizing the assembly of the handle assembly; when operating the switch to unlock and push the locking seats to slide, the handle assembly and the mounting seats can be completely detached from the mounting body.

[0005] Furthermore, the mating surfaces of the first guide member and the second guide member are wedge-shaped guide surfaces, which causes the locking seat and the mounting seat to generate a clamping force during the sliding process.

[0006] Furthermore, the switching switch includes a switch hole disposed on the locking seat; and a switch body having an elastic limiting part, the elastic limiting part being assembled inside the switch hole.

[0007] Furthermore, the elastic limiting part is provided with a guide structure, and the locking seat is provided with a corresponding guide rod; the cooperation between the guide structure and the guide rod is used to limit the locking and unlocking stroke of the switching switch.

[0008] Furthermore, the switching switch includes a switch hole on the locking seat and a switch body with a locking head, the locking head being used to engage with the locking part on the mounting base.

[0009] Furthermore, the first guide member is provided on the outer side of the mounting portion of the mounting base, and the first guide member and the second guide member are configured as guide rails, and the locking base is slidably connected through the second guide member.

[0010] Furthermore, the snap-fit ​​end is fitted into the positioning hole in conjunction with the pin, preventing the handle body from coming out.

[0011] Furthermore, the locking seat and the mounting seat form a receiving space when locked; the snap-fit ​​end has elastic deformation capability and can move telescopically within the receiving space to achieve the switching between the hidden / use state of the handle body.

[0012] Compared with the prior art, this application has the following beneficial effects:

[0013] 1. The handle connection structure provided in this application achieves quick locking / unlocking of the mounting base and the locking base through the cooperation of the sliding locking seat and the switch. The handle assembly and disassembly can be completed without auxiliary tools, improving operational efficiency. The sliding positioning and switch fixation ensure that the handle is stable after assembly, and there is no risk of loosening or falling off during long-term use.

[0014] 2. The handle connection structure provided in this application has a wedge-shaped guide surface for the mating surfaces of the first guide member and the second guide member. During the sliding process, a radial clamping force is automatically generated, which makes the locking seat and the mounting seat tightly press against the installed body, eliminates the installation gap, and improves the vibration resistance.

[0015] 3. The handle connection structure provided in this application has a switch with an elastic limiting part that can be easily embedded in the switch hole of the locking seat, which reduces the complexity of the parts and has a high assembly fault tolerance rate.

[0016] 4. The handle connection structure provided in this application can completely fix the mounting seat and the locking seat by locking the head and mounting seat, preventing them from separating due to vibration.

[0017] 5. The handle connection structure provided in this application can provide clear locking feedback through the guide rod of the locking seat and the guide structure of the switching switch. Moreover, the locking state is irreversible without external force operation, thus ensuring locking reliability.

[0018] 6. The handle connection structure provided in this application has the first guide member and the second guide member configured as guide rails, which can avoid installation offset through linear sliding and improve the smoothness of operation.

[0019] 7. The handle connection structure provided in this application restricts the handle from coming off by engaging with the sales terminal, thereby limiting the handle's freedom of movement and preventing it from accidentally falling off.

[0020] 8. The handle connection structure provided in this application allows the snap-fit ​​end to elastically deform and extend within the accommodating space, thus occupying less space in the stored state, improving aesthetics, and facilitating operation during use. Furthermore, the elastic deformation structure of the snap-fit ​​end can buffer tensile impact and improve the fatigue resistance of the handle. Attached Figure Description

Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, all directional indications (such as up, down, left, right, front, back, bottom, etc.) in this application are only used to explain the relative positional relationships and movements between components in a specific orientation (as shown in the figures). If the specific orientation changes, the directional indication will also change accordingly. Furthermore, descriptions involving "first," "second," etc., in this application are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated.

[0035] like Figure 1-5 As shown, this embodiment provides a handle connection structure, including a housing 10 and a handle assembly. The handle assembly is securely connected during use and easy to assemble and disassemble. The housing 10 has two handle mounting holes. The handle assembly includes a handle 20, a pair of mounting seats 30, and a pair of locking seats 40. The handle 20 has a snap-fit ​​end 21 and a pin inserted therein. The mounting seat 30 has a stop portion 31 and a mounting portion 32. The stop portion 31 has a positioning hole. The handle 20 enters the positioning hole through the snap-fit ​​end 21 and the pin is inserted, making the handle 20 unable to come out.

[0036] like Figure 2-3As shown, the mounting part 32 is inserted into the mounting hole of the housing 10. The size of the stop part 31 is within the mounting hole. A first guide rail 33 is provided on the outer side of the mounting part 32, and a rack part 34 is provided on the inner side. The locking seat 40 is provided on one side of the inner wall of the housing 10. The locking seat 40 is provided with a second guide rail 41. The second guide rail 41 of the locking seat 40 is slidably connected to the first guide rail 33 of the mounting seat 30. A toggle switch 50 is provided on the locking seat 40. When the locking seat 40 slides to the fixed position, the toggle switch 50 is turned off, and the locking seat 40 is fixed relative to the mounting seat 30. The handle 20 is fixed to the housing 10 and cannot be removed. When it is necessary to remove the handle 20, the toggle switch 50 is turned on, and the locking seat 40 is pushed out relative to the mounting seat 30, so that the handle 20 and the mounting seat 30 can be removed from the housing 10 together.

[0037] Regarding the setting of toggle switch 50, such as Figure 5 As shown, in this embodiment, the locking seat 40 has a switch hole, and the toggle switch 50 has two elastic retaining plates 51. The upper end of the elastic retaining plate 51 is configured as a guide with an inclined surface, which can facilitate the toggle switch 50 to be inserted into the switch hole and stop the switch. The end of the elastic retaining plate 51 is configured as a retaining head 52. When the locking seat 40 and the mounting seat 30 are in the same state, the retaining head 52 can engage with the rack portion 34 of the mounting seat 30, thereby fixing the locking seat 40 and the mounting seat 30.

[0038] In other embodiments not shown, the rack portion of the mounting base can be replaced with a locking / locking structure with locking function, such as multiple slots, as long as the mounting base and the locking base can be locked relative to each other when the toggle switch is turned.

[0039] In this embodiment, the elastic plate 51 of the toggle switch 50 is also provided with two guides 53, and the locking seat 40 is provided with a guide rod 42. The guide rod 42 and the guides 53 cooperate during installation to limit the locking and unlocking position travel of the toggle switch 50, and it is not easy to unlock due to vibration or other reasons when locked.

[0040] In other embodiments not shown, the guide and guide rod may be omitted, and the relative stability of the toggle switch position may be achieved through interference fit or other means.

[0041] like Figure 3-4 As shown, regarding the arrangement of the locking seat 40 and the mounting seat 30, the first guide rail 33 of the mounting seat 30 and the second guide rail 41 of the locking seat 40 are wedge-shaped guide rails. When the locking seat 40 is inserted into the mounting seat 30, the locking seat 40 and the mounting seat 30 move closer to each other and press tightly against the housing 10 as guided by the wedge-shaped surface, so that the locking seat 40 and the mounting seat 30 can be firmly installed on the housing 10.

[0042] When the handle is locked, a receiving space is formed between the locking seat 40 and the mounting seat 30. The locking end 21 of the handle 20 is elastic and can move in the receiving space, so that the locking end 21 of the handle 20 is hidden when not in use, and when in use, the locking end 21 is pulled out from the mounting seat 30 to provide the user with a gripping space and cushioning.

[0043] In other embodiments not shown, the handle assembly can be used on non-suitcase structures, such as backpacks, handbags, or other packaging containers.

[0044] The specific embodiments of this application have been described above. Based on the above description, those skilled in the art can make various changes and modifications without departing from the technical concept of this application.
