Description

Technical Field

[0001] The present application relates to the technical field of drawbars, and particularly to a drawbar assembly and a container. Background Art

[0002] In order to achieve the purpose of being durable and reliable after loading, most of the drawbars of toolboxes on the market are customized two-stage drawbars. Although such drawbars can be made as thick and strong as possible and have a small shaking amplitude, the overall height of the drawbar is relatively high and cannot be accommodated in some cases due to insufficient space. Especially for users who need to work while moving, most of the toolboxes with drawbars on the market now cannot be placed in the trunk of a vehicle, such as the trunk of a pickup truck.

[0003] Currently, although some drawbars can be detached from the toolbox, during the process of detaching and installing the drawbar, manual unlocking and manual locking are required, and the disassembly and assembly steps are cumbersome, time-consuming and laborious. Summary of the Utility Model

[0004] In view of this, the present application provides a drawbar assembly with simple operation, time-saving and labor-saving.

[0005] In order to achieve the above purpose, the present application provides the following technical solutions:

[0006] A drawbar assembly includes a fixing part, a connecting rod inserted into the fixing part, and a drawbar inserted into the connecting rod, and further includes a locking structure. The locking structure is arranged on the fixing part and the connecting rod. The locking structure has a locked state and an unlocked state. When the locking structure is in the locked state, the fixing part is fixedly connected to the connecting rod. When the locking structure is in the unlocked state, the fixing part is allowed to be separated from the connecting rod, and the locking structure can automatically remain in the locked state.

[0007] Optionally, the drawbar assembly further includes a holding structure. The holding structure includes a first clamping part and a second clamping part. The first clamping part is arranged on the locking structure and can move with the locking structure. When the first clamping part and the second clamping part are clamped with each other, the locking structure remains in the unlocked state.

[0008] Optionally, the second clamping part is arranged on the connecting rod. When the connecting rod is inserted into the fixing part and the locking structure remains in the unlocked state, the first clamping part and the second clamping part are clamped.

[0009] Optionally, the holding structure further includes a first elastic member. The first elastic member is arranged between the first clamping part and the locking structure, or between the second clamping part and the connecting rod.

[0010] Optionally, when the latch structure moves in the unlocking direction, the first engaging portion crosses the second engaging portion by overcoming the elastic force of the first elastic member.

[0011] Optionally, the first engaging portion includes two telescopic heads slidably connected to the latch structure, and the first elastic member is disposed on the latch structure and between the two telescopic heads to drive the two telescopic heads to protrude from the latch structure.

[0012] Optionally, the connecting rod is provided with a first opening and a second opening that communicate with each other. The width of the first opening is smaller than the width of the first engaging portion to form the second engaging portion at the side of the first opening; the width of the second opening is greater than or equal to the width of the first engaging portion to allow the first engaging portion to pass through the second opening.

[0013] Optionally, the latch structure includes:

[0014] A locking groove provided on the connecting rod;

[0015] A locking member movably disposed on the fixing portion and locking and cooperating with the locking groove. When the latch structure is in the locked state, the locking member interferes with the locking groove. When the latch structure is in the unlocked state, the locking member does not interfere with the locking groove;

[0016] A second elastic member located between the locking member and the fixing portion and capable of driving the locking member to move to interfere with the locking groove so that the latch structure automatically remains in the locked state.

[0017] Optionally, the locking member includes:

[0018] An operating member movably disposed on the fixing portion;

[0019] A locking tongue provided on the operating member and capable of extending into the locking groove under the action of the second elastic member to limit the connecting rod from protruding from the fixing portion;

[0020] Wherein, the locking tongue has a straight surface portion and an inclined surface portion. The straight surface portion abuts against the locking groove so that the latch structure is in the locked state; the connecting rod abuts against the inclined surface portion to drive the latch structure to move in the unlocking direction.

[0021] A container includes the pull rod assembly as described in any one of the above.

[0022] In the drawbar assembly and container of the present application, since the latch structure can be automatically locked, when the connecting rod is inserted into the fixing part, the locking connection between the connecting rod and the fixing part can be automatically achieved. When it is necessary to disassemble the drawbar assembly, only need to manually switch the latch structure to the unlocked state, and then the connecting rod can be pulled out from the fixing part. The operation is simple, time-saving and labor-saving. Description of the Drawings

[0039] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0040] As Figures 1-11 shown, the embodiment of the present application provides a link assembly, including a fixed portion 2, a link rod 3, and a pull rod 4. The link rod 3 is inserted into the fixed portion 2, the pull rod 4 is inserted into the link rod 3, the link rod 3 is detachably connected to the fixed portion 2, and the pull rod 4 can be telescoped relative to the link rod 3 to realize the telescoping of the pull rod 4 relative to the fixed portion 2. Among them, the fixed portion 2 can be set as a fixed rod and fixed or integrally formed on the container, and the container can be set as a suitcase or a toolbox.

[0041] The link assembly further includes a locking structure, which is arranged on the fixed portion 2 and the link rod 3 and is used to lock the link rod 3 on the fixed portion 2; for example, the locking structure is arranged on the side walls of the fixed portion 2 and the link rod 3, or on the ends of the fixed portion 2 and the link rod 3. The locking structure has a locked state and an unlocked state, and the locking structure can be switched between the locked state and the unlocked state through its own actions. When the locking structure is in the locked state, the link rod 3 is fixedly connected to the fixed portion 2 to prevent the link rod 3 from extending out of the fixed portion 2. When the locking structure is in the unlocked state, the connection between the link rod 3 and the fixed portion 2 is cancelled to allow the link rod 3 to extend out of the fixed portion 2. Moreover, the locking structure can automatically remain in the locked state. When the locking structure is not stressed, the locking structure can automatically act in the locking direction to automatically switch the locking structure from the unlocked state to the locked state, thereby realizing the automatic locking of the link rod 3 and the fixed portion 2 by the locking structure.

[0042] Thus, since the buckle structure can be automatically locked, when the connecting rod 3 is inserted into the fixing part 2, the locking connection between the connecting rod 3 and the fixing part 2 can be automatically realized. When the connecting rod assembly needs to be disassembled, only need to manually switch the buckle structure to the unlocked state, and then the connecting rod 3 can be pulled out from the fixing part 2. The operation is simple, time-saving and labor-saving.

[0043] In a preferred solution, the buckle structure includes a locking member 1 and a locking groove 33. The locking groove 33 is arranged on the connecting rod 3. Specifically, the connecting rod 3 is a hollow structure, and the locking groove 33 is a through hole penetrating the side wall of the connecting rod 3. The locking member 1 is arranged on the fixing part 2, and the locking member 1 can move relative to the fixing part 2 (this movement can be set as rotation or sliding, that is, the locking member 1 is rotationally connected or slidably connected to the fixing part 2), so that the locking member 1 can extend into and out of the locking groove 33. When the buckle structure is in the locked state, the locking member 1 extends into the locking groove 33. When the buckle structure is in the unlocked state, the locking member 1 extends out of the locking groove 33. By the locking member 1 extending into and out of the locking groove 33, the switching between the unlocked state and the locked state of the buckle structure is realized. Since the fixing part 2 is arranged as a hollow structure, for the convenience of operation, the locking member 1 is arranged on the outside of the fixing part 2, and the side wall of the fixing part 2 is provided with a through hole for the locking member 1 to extend into the through hole and the locking groove 33 in sequence, so as to realize the clamping between the locking member 1 and the locking groove 33.

[0044] Moreover, the buckle structure further includes a second elastic member 13. The second elastic member 13 is connected between the locking member 1 and the fixing part 2 and can drive the locking member 1 to move relative to the fixing part 2, so that the locking member 1 moves to interfere with the locking groove 33 (that is, the locking member 1 extends into the locking groove 33), and then the buckle structure is automatically kept in the locked state. When the connecting rod 3 is connected to the fixing part 2 and the buckle structure is in the locked state, manually operate the locking member 1 to overcome the elastic force of the second elastic member 13, so that the locking member 1 extends out of the locking groove 33, thereby switching the buckle structure to the unlocked state.

[0045] In this solution, the connecting rod assembly further includes a holding structure. The holding structure includes a first clamping part 11 and a second clamping part 34. The first clamping part 11 is arranged on the buckle structure and can move with the buckle structure. Specifically, the first clamping part 11 is arranged on the locking member 1, and when the locking member 1 moves relative to the fixing part 2, the first clamping part 11 moves relative to the fixing part 2. When the buckle structure moves in the unlocking direction, the first clamping part 11 moves with the buckle structure until the buckle structure moves to the unlocked state. At this time, the first clamping part 11 is clamped with the second clamping part 34 and prevents the buckle structure from moving in the locking direction, thereby keeping the buckle structure in the locked state. Thus, through the arrangement of the first clamping part 11 and the second clamping part 34 in the holding structure, there is no need to manually keep the buckle structure in the unlocked state, which is convenient for disassembling and assembling the connecting rod 3 and the fixing part 2, time-saving and labor-saving, and the operation is simple.

[0046] The second clamping portion 34 is provided on the connecting rod 3. For example, the second clamping portion 34 is a bayonet provided on the side wall of the connecting rod 3. When the connecting rod 3 is inserted into the fixing portion 2, when the locking structure moves in the unlocking direction, the locking member 1 drives the first clamping portion 11 to pass through the side walls of the fixing portion 2 and the connecting rod 3 in sequence, and makes the first clamping portion 11 and the second clamping portion 34 clamp each other, thereby keeping the locking structure in the unlocked state.

[0047] It can be understood that the side wall of the fixing portion 2 is provided with a first through hole 21 and a second through hole 22. When the locking structure moves in the unlocking direction, the locking member 1 drives the first clamping portion 11 to extend into the first through hole 21 so that the first clamping portion 11 cooperates with the second clamping portion 34 on the connecting rod 3. When the locking structure moves in the locking direction, the locking member 1 extends into the second through hole 22 and makes the locking member 1 cooperate with the locking groove 33 on the connecting rod 3.

[0048] In another solution, the second clamping portion 34 can also be provided on the fixing portion 2. When the locking structure drives the first clamping portion 11 to move to be clamped with the second clamping portion 34, the second clamping portion 34 restricts the first clamping portion 11 from moving in the locking direction along with the locking structure, so as to keep the locking structure in the unlocked state.

[0049] In some preferred solutions, the holding structure further includes a first elastic member 12. The first elastic member 12 is provided between the locking structure and the first clamping portion 11. Specifically, the first elastic member 12 is provided between the locking member 1 and the first clamping portion 11 so that the first clamping portion 11 can elastically displace relative to the locking member 1. When a force is applied to make the locking structure move in the unlocking direction, the first clamping portion 11 first moves to abut against the second clamping portion 34. At this time, when the force is continuously applied, the first clamping portion 11 compresses the first elastic member 12 and then displaces relative to the second clamping portion 34 so that the first clamping portion 11 crosses over the second clamping portion 34. After the force application is cancelled, the first elastic member 12 drives the first clamping portion 11 to return to its original position, and the first clamping portion 11 and the second clamping portion 34 clamp each other, thereby preventing the locking structure from moving in the locking direction.

[0050] In addition, the first elastic member 12 can also be provided between the connecting rod 3 and the second clamping portion 34. When a force is applied to make the locking structure move in the unlocking direction, the first clamping portion 11 first moves to abut against the second clamping portion 34. At this time, when the force is continuously applied, the second clamping portion 34 compresses the first elastic member 12 and then displaces relative to the first clamping portion 11 so that the first clamping portion 11 crosses over the second clamping portion 34. After the force application is cancelled, the first elastic member 12 drives the second clamping portion 34 to return to its original position, and the first clamping portion 11 and the second clamping portion 34 clamp each other, thereby preventing the locking structure from moving in the locking direction.

[0051] Thus, when the locking structure moves in the unlocking direction, the first clamping portion 11 can cross over the second elastic member 13 by overcoming the elastic force of the first elastic member 12, which can improve the stability and service life of the structure, and the structure moves smoothly, facilitating user operation.

[0052] Of course, in the case where the first elastic member 12 is not provided, the first clamping portion 11 or the second clamping portion 34 can also be made of an elastic material or an elastic structure, and the first clamping portion 11 and the second clamping portion 34 can be misaligned and crossed over through the elastic deformation of the first clamping portion 11 or the second clamping portion 34 itself.

[0053] In a specific solution, as Figures 3-5 shown, the first clamping portion 11 includes two telescopic heads. An installation hole is provided on the locking member 1, and both telescopic heads are slidably connected in the installation hole. The first elastic member 12 is arranged as a compression spring and abuts between the two telescopic heads to drive the two telescopic heads to displace in a direction protruding from the installation hole, and this displacement direction is perpendicular to the displacement direction of the locking member 1. Moreover, the ends of the two telescopic heads protruding from the installation hole are spherical. When the spherical surface of the telescopic head abuts against the second clamping portion 34, the second clamping portion 34 can apply a force to the telescopic head to make the telescopic head extend into the installation hole, so that the telescopic head is misaligned with the second clamping portion 34.

[0054] In other solutions, as Figure 8 、 Figure 11 shown, the first clamping portion 11 is connected to the locking member 1 through the first elastic member 12. Specifically, the first elastic member 12 is arranged as a spring piece, and the first clamping portion 11 is a block arranged on the spring piece. For example, the first clamping portion 11, the first elastic member 12, and the locking member 1 are integrally formed, and the elastic connection between the first clamping portion 11 and the locking member 1 is realized through the elasticity of the material itself.

[0055] In this solution, a first opening 31 and a second opening 32 are provided on the connecting rod 3. The first opening 31 and the second opening 32 are adjacent and communicate with each other. The width of the first opening 31 is smaller than the width of the first clamping portion 11, and a second clamping portion 34 is formed on the side of the first opening 31, so that the first clamping portion 11 and the second clamping portion 34 can be clamped with each other. Moreover, the width of the second opening 32 is greater than or equal to the width of the first clamping portion 11, that is, the width of the first opening 31 is smaller than the width of the second opening 32, so that the first opening 31 and the second opening 32 form a convex-shaped opening. When the latch structure moves in the unlocking direction, the first clamping portion 11 can cross the first opening 31 and be clamped with the side portion (the second clamping portion 34) of the first opening 31, so that the latch structure is maintained in the unlocked state. When the connecting rod 3 is withdrawn from the fixing portion 2, the first clamping portion 11 is displaced from the first opening 31 to the second opening 32, and the first clamping portion 11 and the second clamping portion 34 are misaligned. The first clamping portion 11 moves along the locking direction with the latch structure and extends out from the second opening 32, so that the first clamping portion 11 will not block the continuous withdrawal of the connecting rod 3; it should be noted that when the first clamping portion 11 extends out from the second opening 32, the locking member 1 and the locking groove 33 are misaligned.

[0056] In some preferred solutions, the locking member 1 includes an operating member and a locking tongue 15. The operating member is provided on the fixing portion 2, and the operating member can move relative to the fixing portion 2 (this movement can be set as rotation or sliding, that is, the operating member is rotatably connected or slidably connected to the fixing portion 2). Specifically, the middle part of the operating member is hinged to the fixing portion 2 through a hinge shaft 14, and this hinged position is between the first through hole 21 and the second through hole 22 on the fixing portion 2. By rotating the operating member relative to the fixing portion 2, the first end and the second end of the operating member can alternately approach the fixing portion 2. Here, a first clamping portion 11 is provided at the first end of the operating member. The first clamping portion 11 is close to the first through hole 21 and can pass through the first through hole 21 to be clamped with the second clamping portion on the connecting rod 3. A locking tongue 15 is provided at the second end of the operating member. The locking tongue 15 is close to the second through hole 22 and can pass through the second through hole 22 to be clamped with the locking groove 33 on the connecting rod 3. The second elastic member 13 is set as a compression spring and abuts between the operating member and the fixing portion 2. This abutting position is between the middle part and the first end of the operating member. Through the elasticity of the second elastic member 13, the first clamping portion 11 on the operating member can move away from the first through hole 21, and the locking tongue 15 on the operating member can move close to the second through hole 22, thereby realizing the automatic locking of the latch structure.

[0057] Among them, the locking tongue 15 has a straight surface portion and an inclined surface portion. In the extending direction of the operating member, the straight surface portion and the inclined surface portion are respectively located on two opposite sides of the locking tongue 15. When the connecting rod 3 is inserted into the corresponding position in the fixing portion 2, the straight surface portion of the locking tongue 15 abuts against the locking groove 33 on the connecting rod 3, so that the buckle structure is in a locked state, thereby preventing the connecting rod 3 from being pulled out of the fixing portion 2. During the process of inserting the connecting rod 3 into the fixing portion 2, the end portion of the connecting rod 3 abuts against the inclined surface portion of the locking tongue 15 and drives the locking tongue 15 to move in the unlocking direction, so that the end portion of the connecting rod 3 passes over the locking tongue 15 until the locking tongue 15 is aligned with the locking groove 33, and the buckle structure is automatically locked. In this way, through the design of the locking tongue 15, the connecting rod 3 can be inserted into the fixing portion 2 without unlocking the buckle structure, and at the same time, automatic locking is completed after the connecting rod 3 is inserted into the fixing portion 2, with simple operation, saving time and effort.

[0058] As Figures 10-11 shown, a sliding groove is provided on the operating member, and the locking tongue 15 is slidably arranged in the sliding groove. A third elastic member 16 (such as a compression spring) is arranged between the locking tongue 15 and the bottom of the sliding groove. Under the action of the third elastic member 16, the locking tongue 15 can displace in the direction away from the operating member. In this way, through the arrangement of the third elastic member 16, the locking tongue 15 can elastically abut against the locking groove 33, improving the locking reliability.

[0059] The present application also provides a container, which can be set as a trolley case or a toolbox, etc. The container includes the connecting rod assembly in the above embodiment. In this way, when the connecting rod 3 is inserted into the fixing portion 2, the locking connection between the connecting rod 3 and the fixing portion 2 can be automatically realized. When it is necessary to disassemble the connecting rod assembly, only need to manually switch the buckle structure to the unlocking state, and then the connecting rod 3 can be pulled out of the fixing portion 2, with simple operation, saving time and effort.
