Technical Field
[0001] This utility model relates to the field of luggage technology, specifically to an assembly structure for a quick-release structure of a suitcase handle. Background Technology
[0002] The handles of existing suitcases adopt an assembly structure, including handle strips, handle bases, and bottom plates. The bottom plate is assembled with the suitcase body and has its own mounting groove for the handle base to be installed. The handle base provides assembly connection for the two ends of the handle strip.
[0003] The existing technology has several problems: traditional suitcase handles require specific tools to disassemble, and consumers have varying needs depending on the environment when carrying a suitcase. For example, in hot weather, sweaty palms necessitate breathable and antibacterial handles. Different consumers have different hand sizes, requiring handles of appropriate sizes. Furthermore, besides their functional carrying and moving capabilities, consumers increasingly value stylish designs. In addition to the patterns, shapes, and colors of the suitcase shell, the handle, as an integral part of the suitcase, stands out prominently and becomes a focal point. Therefore, the design of the handle significantly impacts the overall aesthetics of the suitcase.
[0004] As can be seen from the above, if ordinary consumers can easily disassemble and assemble the handles from the suitcase shell without tools, they can not only change the handles according to their own needs to improve the comfort of using the suitcase, but also quickly change the handles with different styles according to aesthetic preferences, thereby changing the overall design of the suitcase. This will enrich the interaction between consumers and the suitcase, and at a low cost of only purchasing handle accessories, personalize and target the functional structural combinations of the suitcase. Utility Model Content
[0005] To address the shortcomings of the aforementioned technologies, this invention provides a quick-release structure for a suitcase handle.
[0006] The technical solution of this utility model is as follows: A quick-release structure for a suitcase handle includes a handle bar, a pair of handle seats, a pair of locks, a base plate, and several pins. The suitcase shell is provided with an installation port and is fixedly connected to the base plate. The base plate includes an installation groove with an opening facing the outside of the shell. The installation groove is provided with an operating port that extends to the inside of the shell. The locks are movably connected in the installation groove and include a locking position, an unlocking position, and an operating protrusion that passes through the operating port. The two ends of the handle bar are respectively hinged to a pair of handle seats.
[0007] The handlebar base includes a hinged end facing the handlebar bar and an assembly end facing the base plate. The assembly end is inserted into the mounting groove and is detachably fixed to the lock. The operating protrusion drives the lock to move to the locking position to engage and lock the handlebar base, or to move to the unlocking position to unlock it separately from the handlebar base.
[0008] Further features of this invention: The hinged end of the handlebar is provided with a slot. The handlebar is provided with at least one pair of locking protrusions and a travel groove extending through the slot on both sides of the handlebar in the length direction. The two ends of the handlebar in the length direction are symmetrically provided with plugs. The plugs are provided in the slots and their widths are adapted to each other. A pin hole is provided at the position corresponding to the travel groove. The pin is axially fixedly connected to the pin hole, and both ends extend into the travel grooves on both sides for sliding engagement.
[0009] The lock has a sliding groove along the length of the handle bar, with the groove opening facing the handle base. At least one pair of limiting protrusions are provided on the two inner sides of the sliding groove opening, corresponding to the number and shape of the locking protrusions. When the lock moves to the unlocking position, the limiting position of the protrusions is offset from the position of the locking protrusions, and the handle base disengages from the sliding groove opening and the mounting groove opening. When the lock moves to the locking position, the limiting protrusions intercept the path of the locking protrusions as they disengage from the mounting groove, thus locking the handle base.
[0010] A further feature of this invention is that an elastic cantilever is provided along the length of the handle bar at the bottom surface of the sliding groove of the lock component facing the bottom plate, and a button part and a first limiting rack part are provided on one end face of the elastic cantilever facing the bottom plate.
[0011] The inner side of the mounting groove of the base plate is provided with a snap-fit strip that abuts against the end face of the sliding groove of the lock. The snap-fit strip restricts the lock from disengaging from the mounting groove and makes sliding engagement with the lock. The bottom of the mounting groove is provided with an elongated hole that penetrates to the inner side of the housing and a second limiting rack that corresponds to and engages with the first limiting rack.
[0012] A further feature of this invention is that the lock has a U-shaped cross-section, and the elastic cantilever has cuts on both sides.
[0013] A further feature of this invention is that the handlebar seat has a number of spaced locking protrusions on its two sides opposite to the length of the handlebar strip. The two inner sides of the sliding groove opening are provided with a number of limiting protrusions corresponding to the number, spacing, and shape of the locking protrusions. The dimensions of the limiting protrusions and locking protrusions corresponding to the length of the handlebar strip are less than or equal to the spacing.
[0014] A further feature of this invention is that the end face of the locking protrusion facing the handle bar is set as a first inclined surface, and the end face of the limiting protrusion facing away from the handle bar is set as a second inclined surface. Both the first and second inclined surfaces include a high point relatively close to the handle bar and a low point relatively far from the handle bar. The locking position is set on the high point side, and the unlocking position is set on the low point side.
[0015] The suitcase shell covers the end face of the mounting groove. A clamping flange is provided on one side of the handle seat slot. When the lock moves to the locking position, the high point of the limiting protrusion abuts against the high point of the locking protrusion, driving the handle seat closer to the base plate. The clamping flange clamps the suitcase shell with the end face of the mounting groove.
[0016] A further feature of this invention is that the end face of the travel groove near the handlebar is an arc surface, which has a high arc point relatively close to the handlebar and a low arc point relatively far from the handlebar. The high arc point is located near the center point of the handlebar.
[0017] The beneficial effects of this utility model are as follows: The handle assembly structure of this application, through its structural design, allows consumers to easily disassemble, replace, and assemble the handle without tools, enriching the combination of suitcases and handles and reducing the cost of personalized suitcase matching for consumers.
[0018] The specific structure is as follows, as shown in the instruction manual. Figure 5 The operation demonstration shows that the handlebar is assembled into a component by means of a connector, a pin, and a travel groove of the handlebar seat. When installing the handlebar, the two handlebar seats in the component are inserted into the two mounting grooves of the base plate. Then, the operating protrusion is pushed to move the locking component to the locking position. The limiting protrusion is intercepted on the path of the locking protrusion disengaging from the mounting groove, locking the handlebar seat and thus completing the fixed connection.
[0019] When the handlebar needs to be replaced, move the locking mechanism to the unlocking position in reverse. The limiting protrusion will allow the locking protrusion to disengage, and the handlebar can then be unlocked from the locking mechanism, pulled out of the mounting slot, and the assembly can be replaced.
[0020] As per the instruction manual Figure 3 As shown in the cross-section, the design of the elastic cantilever, the first limiting rack, and the second limiting rack ensures that when the lock is not driven by an external force, the elastic cantilever always adheres to the bottom surface of the mounting groove due to its elasticity. The mutual meshing of the first limiting rack and the second limiting rack restricts the displacement of the lock without external force, thereby preventing the handle bar from disassembling on its own.
[0021] During disassembly, the consumer presses the button on the flexible cantilever, causing it to bend away from the bottom of the mounting slot and separate from the rack. Simultaneously, the drive operating protrusion moves the locking mechanism. When the button is released, the flexible cantilever automatically returns to its original shape. The consumer can only control the drive operating protrusion and flexible cantilever from the inside of the luggage compartment, avoiding accidental operation from the outside.
[0022] The design of the first and second inclined surfaces that cooperate with each other at the limiting protrusion and the locking protrusion allows the handle seat to be guided close to the base plate by the inclined surfaces when the lock moves to the locking position, and the pressing flange clamps the luggage box shell, effectively covering the assembly gap at the mounting groove of the base plate.

In the absence of conflict, the embodiments and technical features in the embodiments of this application can be combined with each other to obtain new embodiments.
[0034] The present invention will now be described in detail with reference to the accompanying drawings, such as... Figure 1-8 As shown,
[0035] A quick-release structure for a suitcase handle includes a handle bar 1, a pair of handle bases 2, a pair of locks 4, a base plate 3, and several pins 5. The suitcase shell 6 is provided with an installation port and is fixedly connected to the base plate 3. The base plate 3 includes an installation groove 31 with an opening facing the outside of the shell 6. The installation groove 31 is provided with an operating port 35 that extends to the inside of the shell 6. The locks 4 are movably connected in the installation groove 31 and include a locking position, an unlocking position, and an operating protrusion 441 that passes through the operating port 35. The two ends of the handle bar 1 are respectively hinged to a pair of handle bases 2.
[0036] The handle base 2 includes a hinged end facing the handle bar 1 and an assembly end facing the base plate 3. The assembly end is inserted into the mounting groove 31 and is detachably fixed to the lock 4. The operating protrusion 441 drives the lock 4 to move to the locking position to engage and lock the handle base 2, or to move to the unlocking position to unlock it separately from the handle base 2.
[0037] Further features of this invention: The hinged end of the handle base 2 is provided with a slot 21. The handle base 2 is mirror-image of the two sides of the handle bar 1 along its length direction with at least a pair of locking protrusions 23 and a travel groove 22 extending through the slot 21. The two ends of the handle bar 1 along its length direction are symmetrically provided with plugs 11. The plugs 11 are provided in the slot 21 with their widths adapted to each other, and are provided with pin holes corresponding to the positions of the travel grooves 22. The pins 5 are axially fixedly connected to the pin holes, and their two ends extend into the travel grooves 22 on both sides for sliding engagement.
[0038] The locking component 4 is provided with a sliding groove 41 along the length of the handle bar 1. The groove of the sliding groove 41 faces the handle seat 2. The two inner sides of the groove of the sliding groove 41 are provided with at least a pair of limiting protrusions 42 corresponding to the number and shape of the locking protrusions 23. When the locking component 4 moves to the unlocking position, the limiting position of the protrusions is offset from the position of the locking protrusions 23, and the handle seat 2 disengages from the groove of the sliding groove 41 and the groove of the mounting groove 31. When the locking component 4 moves to the locking position, the limiting protrusions 42 intercept the path of the locking protrusions 23 disengaging from the mounting groove 31, thus locking the handle seat 2.
[0039] Further features of this invention: The sliding contact 41 of the lock 4 faces the bottom surface 44 of the base plate 3, and an elastic cantilever 45 is provided along the length of the handle bar 1. The elastic cantilever 45 is provided with a button part 451 and a first limiting rack part 452 on one side of the end face facing the base plate 3.
[0040] The inner side of the mounting groove 31 of the base plate 3 is provided with a locking strip 32 that abuts against the end face of the sliding groove 41 of the lock 4. The locking strip 32 restricts the lock 4 from disengaging from the mounting groove 31 and slides with the lock 4. The bottom surface 44 of the mounting groove 31 is provided with an elongated hole 33 that penetrates to the inner side of the housing 6 and a second limiting rack part 34 that corresponds to and engages with the first limiting rack part 452.
[0041] A further feature of this invention is that the lock 4 has a U-shaped cross-section, and the elastic cantilever 45 has cutouts on both sides.
[0042] A further feature of this invention is that the handlebar seat 2 is provided with a plurality of spaced locking protrusions 23 on its two sides opposite to the length of the handlebar strip 1. The two inner sides of the sliding groove 41 are provided with a plurality of limiting protrusions 42 corresponding to the number, spacing, and shape of the locking protrusions 23. The plurality of limiting protrusions 42 and locking protrusions 23 correspond to the dimensions of the handlebar strip 1 in the length direction, which are less than or equal to the spacing.
[0043] A further feature of this invention is that the end face of the locking protrusion 23 facing the handle bar 1 is set as a first inclined surface 231, and the end face of the limiting protrusion 42 facing away from the handle bar 1 is set as a second inclined surface 421. Both the first inclined surface 231 and the second inclined surface 421 include a high point relatively close to the handle bar 1 and a low point relatively far from the handle bar 1. The locking position is set on the high point side, and the unlocking position is set on the low point side.
[0044] The suitcase shell 6 covers the end face of the mounting groove 31. A clamping flange is provided on one side of the slot 21 of the handle seat 2. The lock 4 moves to the locking position, and the high point of the limiting protrusion 42 abuts against the high point of the locking protrusion 23, driving the handle seat 2 to approach the base plate 3. The clamping flange clamps the suitcase shell 6 with the end face of the mounting groove 31.
[0045] A further feature of this invention is that the end face of the stroke groove 22 near the handlebar bar 1 is an arc surface, which has an arc high point relatively close to the handlebar bar 1 and an arc low point relatively far from the handlebar bar 1. The arc high point is located near the center point of the handlebar bar 1.
[0046] The beneficial effects of this utility model are as follows: The handle assembly structure of this application, through its structural design, allows consumers to easily disassemble, replace, and assemble the handle without tools, enriching the combination of suitcases and handles and reducing the cost of personalized suitcase matching for consumers.
[0047] The specific structure is as follows, as shown in the instruction manual. Figure 5 The operation demonstration shows that the handle bar 1 is assembled into a combination with the travel groove 22 of the handle seat 2 via the plug 11, the pin 5, and the handle bar 1. When installing the handle bar 1, the two handle seats 2 in the combination are inserted into the two mounting grooves 31 of the base plate 3. Then, the operating protrusion 441 is pushed to move the locking part 4 to the locking position. The limiting protrusion 42 intercepts the locking protrusion 23 on the path of disengaging from the mounting groove 31, locking the handle seat 2, thereby completing the fixed connection.
[0048] When the handle bar 1 needs to be replaced, the locking component 4 is moved to the unlocking position by reversing the operation. The limiting protrusion 42 allows the locking protrusion 23 to disengage from the path, and the handle seat 2 can then be unlocked from the locking component 4 and pulled out from the mounting slot 31 for assembly replacement.
[0049] As per the instruction manual Figure 3 As shown in the cross-section, the design of the elastic cantilever 45, the first limiting rack portion 452, and the second limiting rack portion 34 ensures that when the lock 4 is not driven by external force, the elastic cantilever 45 always adheres to the bottom surface 44 of the mounting groove 31 by relying on its elasticity, and the mutual meshing of the first limiting rack portion 452 and the second limiting rack portion 34 restricts the displacement of the lock 4 without external force, thereby preventing the handle bar 1 from disassembling on its own.
[0050] During disassembly, the consumer presses the button 451 of the elastic cantilever 45, causing the elastic cantilever 45 to bend away from the bottom surface 44 of the mounting groove 31, separating the rack portion. Simultaneously, the drive operating protrusion 441 drives the locking piece 4 to slide. When the button 451 is released, the elastic cantilever 45 automatically returns to its original shape. The consumer can only control the drive operating protrusion 441 and the elastic cantilever 45 from the inside of the suitcase, avoiding the problem of accidental operation due to external contact.
[0051] The design of the first inclined surface 231 and the second inclined surface 421 that cooperate with each other at the limiting protrusion 42 and the locking protrusion 23 allows the lock 4 to move to the locking position and guide the handle seat 2 close to the base plate 3 through the inclined surface cooperation, pressing the flange to clamp the luggage box shell 6, effectively covering the assembly gap at the groove of the mounting groove 31 of the base plate 3.
[0052] The technical solution of this application has been described in conjunction with the preferred embodiments shown in the accompanying drawings. Those skilled in the art should understand that the scope of protection of this application is obviously not limited to these specific embodiments. Without departing from the principles of this application, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the scope of protection of this application.
