Description

Technical Field

[0001] The utility model relates to a bracket, in particular to a jack bracket which is easy to fix. Background Art

[0002] Jack stands, also known as safety stands or insurance stands, are important tools used to ensure safety when repairing or inspecting a vehicle. After the vehicle is lifted using a jack, it is unsafe to rely solely on the jack to support the vehicle because the jack may fail for various reasons. Therefore, it is very necessary to place a jack stand under the vehicle as a second layer of safety.

[0003] After the jack lifts the vehicle, the jack stand needs to be put in, and then the height of the jack stand is adjusted so that the top of the jack stand is against the vehicle, and then the jack stand is fixed. During the process of fixing the jack stand, due to the pressure of the vehicle, the top of the jack stand will fall down, making it difficult to fix, affecting work efficiency. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model aims to provide a jack stand that is easy to fix.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: including a base, a movable jacking pipe and a fixed rod, the movable jacking pipe is vertically slidably arranged on the base, a fixed hole is arranged on the base, a plurality of movable holes opposite to the fixed hole are vertically arranged on the movable jacking pipe, the fixed rod passes through the fixed hole and the movable hole and forms a fixation of the base and the movable jacking pipe, including a fixed pipe, a fixed spring, a fixed block and an unlocking mechanism, a pre-stressing hole is arranged on the base and the pre-stressing hole is opposite to the movable hole, the fixed pipe is arranged on the base and is located at the outer periphery of the pre-stressing hole, the fixed block is slidably arranged in the fixed pipe, the fixed spring is arranged between the fixed pipe and the fixed block and has a pre-fixed state for driving the fixed block to enter the movable hole, and the unlocking mechanism has an unlocking state for driving the fixed block to move out of the movable hole.

[0006] By adopting the above technical scheme, when it is needed, the vehicle is first jacked up by the jack, and then the base with the mobile jacking pipe is placed in, and then the fixing block is withdrawn from the moving hole by the unlocking mechanism, and then the mobile jacking pipe is pulled upward until the top of the mobile jacking pipe is about to collide with the vehicle, and the unlocking mechanism is released. As the mobile jacking pipe continues to move upward, when the next mobile hole is opposite to the fixed pipe, the fixing block enters the mobile hole under the drive of the fixing spring, and the mobile jacking pipe is initially fixed at this time, and the fixed hole is opposite to another mobile hole. Finally, the fixing rod is passed through the fixing hole and another mobile hole to completely fix the mobile jacking pipe and the base. By adding the fixing pipe and the unlocking mechanism, the mobile jacking pipe is initially fixed when it is about to collide with the vehicle, so that the mobile jacking pipe will not fall when the fixing rod is inserted. It is easy to use and has high work efficiency.

[0007] The utility model is further configured as follows: the unlocking mechanism includes an unlocking block and a linkage rod, the unlocking block is arranged on the base, the linkage rod is hinged to the unlocking block, a linkage groove is arranged on the fixed tube and extends to be connected with the fixed block, and the linkage rod is provided with an unlocking part that drives the fixed block to move out of the moving hole.

[0008] By adopting the above technical solution, when unlocking is required, the linkage rod is rotated so that the unlocking part of the linkage rod pushes the fixed block out of the moving hole. At this time, the movable top pipe can move freely, and as long as the linkage rod is pressed continuously, the fixed block cannot enter the moving hole until the top of the movable top rod is about to touch the vehicle, and then the linkage rod is released.

[0009] The utility model is further configured as follows: the base comprises a bottom block and a bottom tube, the bottom tube is vertically arranged on the bottom block, the movable top tube is slidably arranged in the bottom tube, the fixing hole, the fixing tube and the unlocking mechanism are arranged on the bottom tube, a blocking block is arranged in the bottom tube, a matching block is arranged outside the movable top tube and the matching block is located on the relative moving track of the blocking block and constitutes that the movable top tube and the bottom tube do not separate.

[0010] By adopting the above technical solution, the setting of the blocking block and the matching block prevents the movable top pipe from being directly moved out of the bottom pipe.

[0011] The utility model is further configured as follows: a driving spring is arranged between the bottom tube and the movable top tube, the driving spring has a driving state of driving the movable top tube to move upward, a plurality of driving springs are arranged and the plurality of driving springs are staggered with the fixing rod.

[0012] By adopting the above technical solution, the setting of the driving spring can reduce the force of pushing the movable top pipe to move upward, saving effort.

[0013] The utility model is further configured as follows: the top of the movable jacking pipe is provided with a top plate.

[0014] By adopting the above technical solution, the top plate has a large force-bearing area and is convenient for resisting against the vehicle. BRIEF DESCRIPTION OF THE DRAWINGS
