Description

Technical Field

[0001] This utility model relates to a rolling suitcase, and more specifically, to a rolling rod with a pop-out hidden support and a bag using the rolling rod. Background Technology

[0002] A rolling suitcase is a type of luggage with a handle and wheels. Due to its convenience in storing and carrying items, it has become an essential item for business trips and travel.

[0003] As a key feature of rolling suitcases, the pull rod is an important target for improvement in this type of product. With continuous optimization and improvement, a design concept of adding hooks to the handle of the pull rod has emerged in the market. Its main function is to serve as a hanging support for the bag or as a stand for electronic products (mobile phones, tablets).

[0004] For example, a luggage handle assembly disclosed in Chinese Patent Publication No. CN221179650U has the following technical features: it includes a fixed rod, a handle, and a movable rod. A top fixing frame is fitted on the outer side of the top of the fixed rod. A locking structure is provided on one side of the top of the top of the top fixing frame. Suspension structures are provided on both sides of the handle. The suspension structure includes a limiting groove, a torsion spring, a hook, a hook groove, and a rotating shaft. The limiting groove is fixed on both sides of the handle, and a rotating shaft is fixed inside the limiting groove.

[0005] The above-mentioned technical solution provides hooks and also features an automatic reset and storage mechanism. However, in practical applications, such as when a user is holding an electronic product or a handbag in one hand and only has one free hand to operate the hooks, or even needs to operate two hooks simultaneously, it is quite inconvenient to use. Based on these application scenarios, the inventor believes that the existing technology lacks the function of one-click hook deployment, which means that hook deployment is not convenient enough. Therefore, a new solution is needed to solve this problem. Utility Model Content

[0006] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a pull rod with a pop-up hidden bracket and a one-click unfolding function for the hook, effectively improving the convenience of actual use.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a pull rod with a pop-out hidden bracket, including a fixed base, a lower handle cover, an upper handle cover, and a hook. The hook is hinged to the lower handle cover, and the upper handle cover is provided with a storage cavity for the hook to flip and retract. A hook unlocking component is provided between the lower handle cover and the upper handle cover. The hook unlocking component has a vertical range of motion and is connected to an elastic component that drives it to maintain an upward movement tendency. The hook unlocking component is provided with a locking step. The hook is provided with a torsion spring that forces it to unfold, and the hook is provided with a hook portion that cooperates with the locking step.

[0008] By adopting the above technical solution, under normal conditions, the hook flips up and is embedded in the storage cavity, thereby reducing the risk of the hook breaking during luggage check-in or placement. When the user needs to use the hook, force is applied to the hook unlocking part, forcing it to slide downwards. In this state, the hook's holding part is separated from the locking step, and the hook flips outwards to the unfolded state under the elastic potential energy of the torsion spring, thus providing the user with a hanging position or a support position for electronic products. In summary, this application provides a one-click unfolding function for the hook, effectively improving the convenience of actual use.

[0009] The present invention is further configured such that: the hook is provided with a pin hole, a pin is inserted into the pin hole with a gap, and the lower cover of the handle is interference-fitted with an inner pressure member, the inner pressure member cooperating with the lower cover of the handle to fix the two ends of the pin.

[0010] The present invention is further configured such that both the hook and the lower cover of the handle are provided with torsion spring mounting positions centered on the pin.

[0011] The present invention is further configured such that: the hook unlocking component is provided with a force-applying part; the lower cover and upper cover of the handle are both provided with a concave receiving position for accommodating and exposing the force-applying part; a sliding mounting groove is formed between the force-applying part and the main body of the hook unlocking component; and the concave receiving position is provided with a sliding mounting position for sliding connection of the sliding mounting groove.

[0012] The present invention is further configured such that the elastic element is a compression spring, which is compressed between the hook unlocking element and the handle cover.

[0013] The present invention is further configured such that both the hook and the locking step are provided with inclined mating surfaces, and the inclined mating surfaces of the two cooperate with each other to generate a component force that pushes the hook unlocking component downward.

[0014] The present invention is further configured such that: the fixing seat is provided with a protruding plate within the vertical projection of the hook, and the protruding plate is in surface-fitting connection with the hook in the vertical state.

[0015] The present invention is further configured such that: the handle cover has a top mounting position, and the top mounting position has a telescopic rod control button; the telescopic rod control button and the hook unlocking component are vertically slidably attached to each other.

[0016] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a bag that uses a pop-up hidden bracket pull rod, which ensures that the handle and the fixed base can be completely retracted into the assembly position, making it convenient for the bag to be transported or placed.

[0017] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a bag using a pop-out hidden bracket pull rod, including a bag body, the bag body being provided with an assembly position, the fixing seat being fitted into the assembly position, and the fixing seat being provided with an assembly stud for bolting to the bag body.

[0018] By adopting the above technical solution, the fixing seat is embedded in the assembly position and fastened with bolts. When the bag needs to be transported or placed, the handle assembly consisting of the lower handle cover and the upper handle cover is embedded in the fixing seat, thereby ensuring that the handle assembly and the fixing seat can be completely retracted into the assembly position, which facilitates the transport or placement of the bag.

[0019] The present invention is further configured such that: a telescopic rod mounting hole is provided through the assembly position and the fixing seat, and a telescopic rod is fixed in the telescopic rod mounting hole.

[0020] In summary, the pull rod provided by this utility model has the following beneficial effects: it provides a one-click unfolding function for the hook, effectively improving the convenience of actual use; through the rotational insertion and cooperation of the pin hole and the pin, the hook and the lower cover of the handle are hinged, which has the technical effect of convenient assembly; the torsion spring mounting position provides sufficient space for the installation of the torsion spring, ensuring that the torsion spring has a sufficient number of coils to store elastic potential energy; the flipping and retraction of the hook and the downward retraction of the entire handle are linked, which not only improves the convenience of use for users, but also avoids the hidden danger of forgetting to flip and retract the hook, effectively preventing the hook from breaking during pushing; and it achieves the technical requirement of setting two sets of control components in the small space of the handle.

[0021] The bag provided by this utility model has the following beneficial effects: it ensures that the handle and the fixing base can be fully retracted into the assembly position, which facilitates the transport or placement of the bag. Attached Figure Description

[0032] The present invention will be further described in detail below with reference to the accompanying drawings.

[0033] Example 1: A pull rod with a pop-up hidden bracket, such as Figure 1 , Figure 2 As shown, it includes a fixed base 5, a lower handle cover 3, an upper handle cover 7, and a hook 1. The hook 1 is hinged to the lower handle cover 3. The upper handle cover 7 is provided with a storage cavity 7-2 for the hook 1 to flip and retract. A hook unlocking component 4 is provided between the lower handle cover 3 and the upper handle cover 7. The hook unlocking component 4 has a vertical range of motion and is connected to an elastic component 10 that drives it to maintain an upward movement tendency. The hook unlocking component 4 is provided with a locking step 4-3. The hook 1 is provided with a torsion spring 9 that forces it to unfold. The hook 1 is provided with a hook part 1-1 that cooperates with the locking step 4-3.

[0034] In its normal state, the hook 1 is flipped up and embedded in the storage cavity 7-2, thereby reducing the risk of the hook 1 breaking during baggage check-in or placement. When the user needs to use the hook 1, force is applied to the hook unlocking part 4, forcing it to slide downward. In this state, the hook holding part 1-1 of the hook 1 separates from the locking step 4-3, so that the hook 1 flips outward to the unfolded state under the elastic potential energy of the torsion spring 9, thus providing the user with a hanging position or a support position for electronic products.

[0035] Hook 1 is hinged to the lower cover 3 of the handle in the following manner, such as... Figure 2 , Figure 3 , Figure 4As shown, the hook 1 is integrally formed with pin holes 1-2, and a pin 8 is inserted into the pin holes 1-2 with a gap. The handle cover 3 is interference-fitted with an inner pressure member 2. The inner pressure member 2 cooperates with the handle cover 3 to fix the two ends of the pin 8. The handle cover 3 cooperates with the inner pressure member 2 to fix the two ends of the pin 8. Thus, the hook 1 and the handle cover 3 are hinged through the rotational insertion and cooperation of the pin holes 1-2 and the pin 8, which has the technical effect of convenient assembly.

[0036] It should be noted that, as Figure 3 , Figure 4 As shown, both the hook 1 and the handle cover 3 are provided with torsion spring mounting positions 1-3 centered on the pin 8, thus providing sufficient space for the installation of the torsion spring 9 and ensuring that the torsion spring 9 has a sufficient number of coils to store elastic potential energy.

[0037] The hook unlocking component 4 is positioned between the lower handlebar cover 3 and the upper handlebar cover 7 in the following manner: Figure 2 , Figure 4 , Figure 5 As shown, the hook unlocking component 4 is provided with a force-applying part 4-1. Both the lower handle cover 3 and the upper handle cover 7 are provided with recessed receiving positions 3-4 for accommodating and exposing the force-applying part 4-1. On the one hand, users can directly apply force to the force-applying part 4-1 with their fingers to ensure the convenience of one-click unfolding of the hook 1. On the other hand, it avoids the force-applying part 4-1 from protruding from the side of the handle assembly composed of the lower handle cover 3 and the upper handle cover 7, so as not to affect the user's grip comfort. A sliding mounting groove 4-2 is formed between the force-applying part 4-1 and the main body of the hook unlocking component 4. The recessed receiving position 3-4 is provided with a sliding mounting position 7-3 for sliding connection of the sliding mounting groove 4-2. Thus, by utilizing the cooperation between the sliding mounting groove 4-2 and the sliding mounting position 7-3, the movement of the hook unlocking component 4 is restricted, so that it only has the longitudinal sliding movement, ensuring the stability of the hook unlocking component 4 in use.

[0038] In this embodiment, the elastic element 10 is a compression spring, which is compressed between the hook unlocking element 4 and the handle lower cover 3, thereby directly pushing the hook unlocking element 4 upward; in other embodiments, the elastic element 10 can also be a tension spring, that is, it is set between the hook unlocking element 4 and the handle upper cover 7, applying an upward pulling force to the hook unlocking element 4.

[0039] To facilitate the flipping and retraction of hook 1, as follows: Figure 3 , Figure 5As shown, both the hook part 1-1 and the locking step 4-3 are provided with inclined mating surfaces 4-4. The inclined mating surfaces 4-4 of the two cooperate to generate a component force that pushes the hook unlocking member 4 downward. When it is necessary to flip and retract the hook 1, the user directly applies force to the hook 1. Thus, with the cooperation of the two inclined mating surfaces 4-4, the hook unlocking member 4 is first pushed downward. When the hook 1 is in the fully retracted state, the two inclined mating surfaces 4-4 are misaligned. At this time, the elastic member 10 releases elastic potential energy and pushes the hook unlocking member 4 upward, thereby completing the hook connection between the hook part 1-1 and the locking step 4-3.

[0040] To further improve user convenience, such as Figure 1 , Figure 2 As shown, the fixed base 5 has a protruding plate 5-3 integrally formed within the vertical projection of the hook 1. The protruding plate 5-3 is in face-fitting connection with the hook 1 in the vertical state. When the user pushes the handle assembly consisting of the lower handle cover 3 and the upper handle cover 7 back to the fixed base 5, the protruding plate 5-3 applies force to the hook 1, forcing it to flip and retract. When the handle assembly is fully retracted, the hook 1 directly completes the hook-locking connection with the hook unlocking component 4. In summary, the flipping and retraction of the hook 1 is linked with the downward retraction of the handle assembly, which not only improves the user's convenience but also avoids the hidden danger of forgetting to flip and retract the hook 1, effectively preventing the hook 1 from breaking during pushing.

[0041] In this embodiment, the telescopic rod is controlled using a conventional steel cable control buckle structure. This is a standard design in the prior art, and the cited documents in the background art have already provided sufficient information, so it will not be repeated here. The design focus of this application is that the structures controlling the telescopic rod 11-3 and the hook 1 both need to be located between the upper handle cover 7 and the lower handle cover 3, requiring high space utilization. Therefore, as follows... Figure 6 , Figure 7 As shown, the handle top cover 7 is provided with a top mounting position 7-1, and the top mounting position is provided with a telescopic rod control button 6. The telescopic rod control button 6 and the hook unlocking component 4 are vertically slidably attached to each other. Thus, the handle top cover 7 provides the main assembly space for the telescopic rod control button 6, and the handle bottom cover 3 provides the main assembly space for the hook unlocking component 4. The hook unlocking component 4 and the telescopic rod control button 6 are vertically offset, thereby achieving the technical requirement of setting two sets of control components in the small space of the handle.

[0042] Example 2: A type of bag using a pop-up hidden support rod, such as... Figure 8 , Figure 9As shown, the bag includes a main body 11, which has an assembly position 11-1. A fixing seat 5 is fitted into the assembly position 11-1, and the fixing seat 5 is provided with an assembly stud 5-1 for bolting to the main body 11. When the bag needs to be transported or placed, the handle assembly consisting of the lower handle cover 3 and the upper handle cover 7 is embedded in the fixing seat 5, thereby ensuring that the handle assembly and the fixing seat 5 can be completely retracted into the assembly position 11-1, which facilitates the transport or placement of the bag.

[0043] In this embodiment, the specific installation method of the telescopic rod 11-3 is as follows: a telescopic rod mounting hole 11-2 is provided through the assembly position 11-1 and the fixed seat 5. The telescopic rod 11-3 is fixed in the telescopic rod mounting hole 11-2, so that the fixed section of the telescopic rod 11-3 is installed in the fixed seat 5 and hidden in the main body 11 of the bag. The top of the movable section of the telescopic rod 11-3 is fixed to the handle cover 3.

[0044] The specific embodiments are merely explanations of this utility model and are not intended to limit it. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this utility model.
