Description

Technical Field

[0001] The invention relates to the technical field of automobile parts hoisting, and in particular to an air bag support arm hook assembly, a hoisting auxiliary tool and a use method. Background Art

[0002] Traditional lifting aids are mainly composed of hooks, chains, hinges and L-shaped hooks. The lifting position is the extension of the two arms of the parts. This lifting method is suitable for lifting symmetrical parts. The airbag support arm is an asymmetrically arranged part with the center of gravity offset to one side of the part. When using traditional lifting aids to lift the airbag support arm, the L-shaped hook is hung on the bottom of the outer wall of the airbag support arm, which is prone to unstable lifting and part overturning, that is, the airbag support arm directly slides off the L-shaped hook, thereby reducing the stability of the airbag support arm lifting.

[0003] CN212503594U relates to a device for hoisting a V-shaped thrust rod of a commercial vehicle, comprising a movable device and a fixing device, wherein the movable device comprises a parent-child ring and an eye hook, the fixing device comprises a support frame and at least two pairs of locking hooks, the locking hook comprises a handle and a semicircular head, the parent-child ring is connected to the handle of the locking hook through a chain, the eye hook is connected to the parent-child ring through a steel wire rope, the locking hook and the support frame are rotatably connected, the connection point between the locking hook and the support frame is close to the head, and a lifting ring is fixed at the geometric center position of the support frame.

[0004] However, the prior art is only for the hoisting of the V-type thrust rod of the automobile, and cannot be applied to the hoisting of the airbag support arm, and cannot solve the problem that the hoisting of the airbag support arm is prone to unstable hoisting and overturning of parts. Summary of the invention

[0005] The purpose of the present invention is to provide an airbag support arm hook assembly, a lifting aid and a use method, which can improve the stability of the airbag support arm lifting and solve the problems of unstable lifting and parts overturning in the prior art.

[0006] The present invention provides the following solution

[0007] An air bag support arm hook assembly includes a lifting handle, which is an L-shaped structure. One end of the lifting handle is provided with a connecting hole, and the other end of the lifting handle is fixedly connected to a connecting sleeve. A plug-in rod is detachably connected to the connecting sleeve. The lifting handle, the connecting sleeve and the plug-in rod together form a U-shaped structure.

[0008] The plug-in rod can be inserted into the hole on the airbag support arm, thereby improving the stability of the hook assembly in lifting the airbag support arm; the overall U-shaped structure of the hook can ensure that the plug-in rod is facing upward during lifting, and the lifted parts are not easy to slip.

[0009] Furthermore, the hook assembly also includes a locking assembly, which is fixedly connected to the bottom surface of the lifting handle, the plug-in rod is slidably connected to the connecting sleeve, and the bottom of the plug-in rod can be vertically plugged into the locking assembly.

[0010] The plug-in rod is installed in the connecting sleeve, and its bottom is vertically plugged into the locking assembly to achieve locking; therefore, when the plug-in rod is bent by the gravity of the airbag support arm or needs to be replaced for airbag support arms of different models or holes of different sizes, the locking assembly can be released to unlock the plug-in rod and directly replace the plug-in rod.

[0011] Furthermore, the locking assembly includes an outer shell, which includes a fixed cylinder and a locking groove; the top surface of the fixed cylinder is fixedly connected to the bottom surface of the lifting handle, and the end of the fixed cylinder close to the connecting sleeve is fixedly connected with a locking groove, and the locking groove is fixedly connected to directly below the connecting sleeve. The top surface of the locking groove is provided with a through hole, which is connected to the connecting sleeve, and the lower part of the plug-in rod can be inserted into the locking groove through the through hole; a locking rod is limitedly sleeved inside the fixed cylinder, and a limit spring is sleeved outside the locking rod, and the locking rod can be vertically plugged into the plug-in rod.

[0012] The locking rod can be vertically plugged into the plug-in rod, so that the installation and replacement of the plug-in rod are more convenient and more efficient.

[0013] Furthermore, a locking hole is provided on the lower side wall of the plug-in rod, and the inner end of the locking rod is the locking end, which can pass through the connecting end surface of the fixing tube and the locking groove and be plugged into the locking hole; a limiting flange is provided in the middle part of the locking rod, and a limiting ring is fixedly connected to the inside of one end of the fixing tube away from the locking groove, and the limiting spring is stopped between the limiting flange and the limiting ring.

[0014] The limit spring can apply an outward elastic force to the locking rod, thereby ensuring the stability of the plugging connection between the locking rod and the plugging rod.

[0015] Furthermore, a handle is fixedly connected to the outer end of the locking rod, and the handle is a strip-shaped structure. The locking assembly also includes a limit block, and the limit block is arranged on the side of the handle away from the fixed tube; the limit block includes a fixing portion and a clamping portion, the fixing portion is fixedly connected to the bottom surface of the lifting handle, and the clamping portion is fixedly connected to the inner side surface of the fixing portion; a clamping groove is provided at a position opposite to the handle and the clamping portion, and the clamping portion can be slidably clamped with the clamping groove.

[0016] The setting of the limit block and the clamping groove can improve the stability of the handle when it is limited by the limit block. Since the handle is a strip structure, the handle can be separated from the limit block by rotating the handle to a horizontal state, and the locking rod can be pulled by the handle.

[0017] Furthermore, the plug-in rod and the connecting sleeve are threadedly connected.

[0018] The hook assembly eliminates the locking assembly and replaces it with a threaded connection, which makes the structure simpler and easier to process.

[0019] An airbag support arm lifting auxiliary tool comprises the airbag support arm hook assembly as described above, and also comprises a hanging ring, the bottom of the hanging ring is nested and connected with a chain, and the end of the chain is nested and connected to the lifting handle of the hook assembly.

[0020] The hanging ring can be conveniently hung on the hook of the lifting equipment, and the chain can be conveniently loaded and unloaded on the hook assembly.

[0021] Furthermore, it also includes a connecting ring, a hinge is pivotally connected in the connecting hole of the lifting handle, and the hanging ring and the chain, as well as the chain and the hinge are nested and connected through the connecting ring.

[0022] The connecting ring can be opened or closed, which is convenient for disassembly and replacement of the chain and the hook; the hinged part is pivotally connected to the lifting handle, which has higher connection strength and makes the hook assembly easier to rotate.

[0023] Furthermore, at least two of the chains are nested and connected on the hanging ring, and one end of each chain is nested and connected to a hook assembly.

[0024] Multiple sets of chains and hook components are nested and connected on the hanging ring, which can lift multiple airbag support arms at the same time, improving the lifting efficiency.

[0025] A method for using an airbag support arm lifting aid, based on the above-mentioned airbag support arm lifting aid, comprises the following steps:

[0026] Select the corresponding plug-in rod according to the lifting hole in the middle of the airbag support arm to be lifted;

[0027] Connect the splice rod to the connecting sleeve and secure it;

[0028] Insert the plug rod into the lifting hole of the airbag support arm, hang the hanging ring on the hook of the lifting equipment, and carry out the lifting work;

[0029] After the lifting is completed, pull the connecting rod out of the lifting hole.

[0030] Compared with the prior art, the present invention has the following advantages:

[0031] The airbag support arm hook assembly, lifting aid and use method provided by the present invention utilize the coordinated use of a hanging ring, a chain and a hook assembly. The hook assembly includes a lifting handle, a plug-in rod, a connecting sleeve and a locking assembly. When the airbag support arm is lifted, the plug-in rod can be plugged into the hole of the airbag support arm, thereby improving the stability of the hook assembly in lifting the airbag support arm; the plug-in rod is easy to disassemble and replace, can be applicable to a variety of vehicle models, and has good versatility; it can also lift multiple airbag support arms at one time, thereby improving lifting efficiency; and solves the problems of unstable lifting and parts overturning that are prone to occur in the prior art.
