Description

Technical Field

[0001] This application relates to a throttle unlocking structure. Background Technology

[0002] A stroller in the current technology is a tool vehicle designed to facilitate infants' outdoor activities. It serves as a means of transportation for babies when going out and is an essential item for infant care. Currently, most strollers on the market are foldable for easy storage and transportation. There are many types of foldable strollers available, with varying folding principles and methods, but they often include a locking mechanism between two or more rotating parts, which is unlocked via an unlocking component. Currently, most unlocking components on the market are operated by pressing, sliding, or rotating. However, during use, accidental unlocking can easily occur due to accidental contact, thus safety needs improvement. Summary of the Invention

[0003] The purpose of this application is to provide a simple throttle unlocking structure that can effectively prevent accidental unlocking.

[0004] The technical solution of this application is: a throttle unlocking structure, including a connecting pipe, a locking component disposed inside the connecting pipe and retractable relative to it to control whether it is locked or not, and a throttle component disposed in the middle of the connecting pipe and which can be unlocked by rotating the locking component. The throttle component is provided with a limiting member that can slide laterally relative to it, and a first reset member is provided between the limiting member and the throttle component. The limiting member has a protrusion on its inner side, and the middle of the connecting pipe has a limiting step opposite to the protrusion and limiting the protrusion when the locking component is in the locked state, and a guide groove that allows the protrusion to slide when the throttle component is rotated. The limiting step and the guide groove are located at different axial positions of the connecting pipe and are arranged adjacent to each other. The limiting member can switch its protrusion between the limiting step and the guide groove by sliding.

[0005] When the locking component is in the locked state, the limiting member pops out under the elastic action of the first reset member so that its protruding part abuts against the limiting step. At this time, the throttle assembly cannot rotate relative to the connecting tube, thereby realizing the unlocking operation of the locking component.

[0006] When the locking component needs to be unlocked, the sliding limit piece causes its protruding part to move laterally into the guide groove, thereby releasing the limit lock on the throttle assembly. At this time, the throttle assembly can rotate relative to the connecting pipe, thus realizing the unlocking operation of the locking component.

[0007] As a preferred technical solution, a fixing seat is provided in the middle of the connecting pipe, and the limiting step and the guide groove are both formed on the fixing seat.

[0008] As a preferred technical solution, the throttle assembly includes a rotating component sleeved in the middle of the connecting tube and a throttle handle that covers the rotating component and is fixedly fitted thereto. The rotating component has an opening for the fixed seat to be inserted and rotated.

[0009] As a preferred technical solution, the rotating component has a sliding groove that slides with the limiting component, and the throttle has a through groove for the limiting component to pass through; the first reset component is disposed between the limiting component and the throttle, and when the protrusion abuts against the limiting step, both ends of the limiting component protrude from the through groove of the throttle to form a pressing part.

[0010] As a preferred technical solution, the protrusion of the limiting member is formed in its central position and consists of two arc-shaped blocks arranged at intervals; the fixing base has two corresponding limiting steps and three guide grooves, with the two limiting steps spaced between the three guide grooves. This design allows the limiting member to release the locking limit on the throttle assembly regardless of whether it moves to the left or right, making the unlocking operation more convenient.

[0011] As a preferred technical solution, the throttle includes a throttle sleeve fitted over the rotating component and a grip extending to one side from the throttle sleeve.

[0012] As a preferred technical solution, the locking assembly includes a locking tongue disposed at both ends of the connecting tube and slidable relative to its axial direction, a second reset member disposed between the locking tongue and the connecting tube, and a traction cable connecting the locking tongue and the rotating member.

[0013] Compared with the prior art, this application has the following advantages:

[0014] This application achieves locking between the connecting tube and other components of the frame by the telescopic sliding of a locking component, and unlocks the locking component by rotating the throttle assembly. To prevent accidental unlocking due to accidental contact with the throttle assembly, a limiting member is used to lock the throttle assembly on the connecting tube when it is in use (locking component is locked), preventing unlocking. To unlock, the limiting member must first be slid to release the limiting member's lock on the throttle assembly before the throttle assembly can be rotated to unlock it. This design is simple, safe, reliable, and effectively prevents accidental unlocking. Attached Figure Description

[0033] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the described embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. It is understood that, without conflict, some technical means of the various embodiments described herein can be substituted for or combined with each other.

[0034] In the description of this application and the claims, the terms "first," "second," etc., are used only to distinguish the described objects and have no sequential or technical meaning. Therefore, objects specified with "first," "second," etc., may explicitly or implicitly include one or more of those objects. Furthermore, the words "one" or "a" do not indicate a quantity limitation, but rather indicate the presence of at least one, while "multiple" indicates not less than two.

[0035] In the description of this application and the claims, the terms "connection," "installation," "fixation," and "reception," unless otherwise specified, should be interpreted broadly. For example, "connection" can mean a separate connection or an integral connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean a non-detachable connection or a detachable connection. As another example, "reception" does not necessarily mean complete containment; this concept also includes the containment of a portion that protrudes externally. Those skilled in the art can understand the specific meaning of the aforementioned terms in this application based on the specific circumstances.

[0036] In the description of this application and the claims, if terms such as "above," "below," or "horizontal" indicate orientation or positional relationships based on the orientation or positional relationships shown in the drawings, they are only for the purpose of clearly and simply describing this application, and do not indicate or imply that the elements referred to must have a specific orientation or be constructed and operated in a specific orientation. These directional terms are relative concepts used for relative description and clarification, and may change accordingly depending on the orientation of the components in the drawings. For example, if the device in the drawings is flipped, an element described as "below" other elements will be positioned "above" other elements.

[0037] In the description of this application specification and claims, the term "if" is generally interchangeable with "when," "at," "in response to determination," or "in response to detection," depending on the context.

[0038] In the description of this application and the claims, if there is a "direction" of motion, including motion with a directional component, the term "in direction" is not necessarily understood as motion only in that one direction. Those skilled in the art can understand the specific meaning of the aforementioned terms in this application according to the specific circumstances.

[0039] like Figures 1 to 11 As shown, a throttle unlocking structure includes a connecting pipe 1, a locking component 2 disposed within the connecting pipe and extendable relative to it to control whether it is locked or not, and a throttle component 3 disposed in the middle of the connecting pipe 1 and which can be unlocked by rotating the locking component 2. The throttle component 3 is provided with a limiting member 4 that can slide laterally relative to it, and a first reset member 5 is provided between the limiting member 4 and the throttle component 3. The limiting member 4 has a protrusion 401 on its inner side. The middle of the connecting pipe 1 has a limiting step 101 opposite to the protrusion 401 and limiting the protrusion 401 when the locking component 2 is in the locked state, and a guide groove 102 that allows the protrusion 401 to slide when the throttle component 3 is rotated. The limiting step 101 and the guide groove 102 are located at different axial positions of the connecting pipe 1 and are arranged adjacent to each other. The limiting member 4 can switch its protrusion 401 between the limiting step 101 and the guide groove 102 by sliding.

[0040] In this embodiment, a fixing seat 103 is provided in the middle of the connecting pipe 1 and fixed thereto. The limiting step 101 and the guide groove 102 are both formed on the fixing seat 103.

[0041] In this embodiment, the throttle assembly 3 includes a rotating component 301 sleeved in the middle of the connecting pipe 1 and a throttle 302 covering the rotating component 301 and fixedly engaged with it. The rotating component 301 has an opening 3011 for the fixed seat 103 to be inserted and rotated.

[0042] In this embodiment, the rotating member 301 has a sliding groove 3012 that slides with the limiting member 4, and the throttle 302 has a through groove 3021 for the limiting member 4 to pass through; the first reset member 5 is disposed between the limiting member 4 and the throttle 302, and when the protruding part 401 abuts against the limiting step 101, both ends of the limiting member 4 are exposed in the through groove 3021 of the throttle 302 to form a pressing part 402.

[0043] In this embodiment, the protrusion 401 of the limiting member 4 is formed in its central position and consists of two arc-shaped blocks arranged at intervals; the fixing base 103 has two corresponding limiting steps 101 and three guide grooves 102, with the two limiting steps 101 spaced apart between the three guide grooves 102. This design allows the limiting member 4 to release the locking limit on the throttle assembly 3 regardless of whether it moves to the left or right, making the unlocking operation more convenient.

[0044] In this embodiment, the throttle 302 includes a throttle sleeve 3022 sleeved on the rotating member 301 and a grip 3023 extending to one side from the throttle sleeve 3022.

[0045] In this embodiment, the locking assembly 2 includes a locking tongue 201 disposed at both ends of the connecting pipe 1 and slidable relative to it axially, a second reset member 202 disposed between the locking tongue 201 and the connecting pipe 1, and a traction cable 203 connecting the locking tongue 201 and the rotating member 301. The fixed base 103 and the rotating member 301 each have grooves for the traction cable 203 to pass through.

[0046] The working principle of this application is as follows:

[0047] like Figures 1 to 6 As shown, when the locking component 2 is in the locked state, the handle 3023 of the throttle component 3 is arranged downwards. The limiting member 4 pops out under the elastic action of the first reset member 5, so that its protruding part 401 abuts against the lower part of the limiting step 101. The upper rear edge of the rotating member 301 abuts against the upper rear edge of the fixed base 103. At this time, the throttle component 3 cannot rotate relative to the connecting pipe 1, thereby realizing the unlocking operation of the locking component 2.

[0048] like Figures 7 to 11As shown, when the locking component 2 needs to be unlocked, the sliding limit member 4 causes its protruding part 401 to move laterally from the limit step 101 into the guide groove 102, thereby releasing the limit lock on the throttle assembly 3. At this time, the throttle assembly 3 can rotate relative to the connecting pipe 1, thus realizing the unlocking operation of the locking component 2. In this embodiment, the unlocking operation is to rotate the throttle assembly 3 upward. If the throttle assembly 3 is rotated upward at this time, the protruding part 401 of the limit member 4 slides in the guide groove 102, and the rotating part 301 pulls the locking tongue 201 inward through the traction cable 203 to exit the corresponding locking groove, thereby releasing the lock on other parts of the stroller.

[0049] If it is necessary to lock other parts of the stroller again, the other parts are unfolded or moved to the position of the locking tongue 201 corresponding to their locking groove. At this time, the locking tongue 201 pops out and automatically locks into the locking groove under the reset action of the second reset member 202, so that the locking component 2 enters the locked state. At this time, the traction cable 203 releases the rotating member 301, and the throttle assembly 3 rotates downward under its own weight. When the protrusion 401 of the limiting member 4 slides in the guide groove 102 to one side of the limiting step 101, the limiting member 4 is reset under the reset action of the first reset member 5, so that its protrusion 401 abuts against the limiting step 101. At this time, the throttle assembly 3 cannot rotate relative to the connecting pipe 1 to achieve the unlocking operation of the locking component 2, so that the locking component remains in the locked state.

[0050] This application achieves locking or unlocking between the connecting tube 1 and other components of the frame through the telescopic sliding of the locking component 2, and unlocks the locking component 2 by rotating the throttle assembly 3. To prevent accidental unlocking due to accidental contact with the throttle assembly 3, a limiting member 4 is used to limit and lock the throttle assembly 3 on the connecting tube 1 when it is in use (locking component 2 is in the locked state), preventing it from unlocking the locking component 2. When unlocking is required, the limiting member 4 must be slid to release the limiting member 4 from the limiting lock on the throttle assembly 3 before the throttle assembly 3 can be rotated to unlock the locking component 2. This design is simple, safe, reliable, and effectively prevents accidental unlocking.
