Description
Technical Field
[0001] The utility model relates to the technical field of lifting equipment, in particular to a triangular jack lifting frame. Background Art
[0002] A jack is a light and small lifting device that uses a rigid lifting piece as a working device to lift heavy objects through a small stroke of the top support or bottom claws. Jacks are mainly used in factories, mines, transportation and other departments for vehicle repairs and other lifting and supporting work. Its structure is light and strong, flexible and reliable, and can be carried and operated by one person.
[0003] Although the traditional jack can meet the basic lifting needs, it has shortcomings in terms of stability and convenience of height adjustment. Especially in situations where precise height control and stable structure are required, the traditional jack is difficult to meet the needs. Therefore, it is particularly important to design a triangular jack lifting frame that is both stable and easy to adjust the height. Utility Model Content
[0004] The purpose of the utility model is to provide a triangular jack lifting frame to solve the problems raised in the above background technology.
[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a triangular jack lifting frame, comprising a supporting mechanism, a fixing mechanism is arranged on one side of the supporting mechanism, and an adjusting mechanism is arranged on the top of the supporting mechanism;
[0006] The support mechanism comprises a bracket, one end of the bracket is fixedly connected to an outer cylinder, the bottom of the bracket is fixedly connected to an anti-sliding block, and one side of the bracket is fixedly connected to a connecting frame;
[0007] The fixing mechanism comprises a first circular ring, a connecting chain is sleeved on the surface of the first circular ring, a second circular ring is sleeved on one end of the connecting chain away from the first circular ring, and a latch is arranged on the surface of the second circular ring.
[0008] Furthermore, the triangular jack lifting frame is placed under the object that needs to be lifted, ensuring that the anti-slip block at the bottom of the bracket is in close contact with the ground or supporting surface to increase stability, and the floor jack is used to lift the vehicle high enough to lift the vehicle to a higher height and position as required, and then the triangular jack lifting frame is placed under the vehicle that needs to be lifted, and one end of the pin is passed through the through holes on the outer tube and the lifting column to ensure the stability and safety of the fixing mechanism, and the lifting column is rotated or operated to move up and down in the slide groove at the top of the outer tube to adjust the height of the lifting platform according to actual needs. When the required height is reached, the pin is used to pass through the corresponding through hole to fix the lifting column and the outer tube together to prevent it from sliding down on its own, and the object that needs to be supported or lifted is placed on the lifting platform. The design of the anti-slip pad helps to increase friction and prevent objects from sliding. Users can easily adjust the support height to meet support requirements in different scenarios.
[0009] Preferably, three of the brackets and the connecting frames are provided, and the three brackets and the connecting frames form a tripod structure.
[0010] Furthermore, the number of the brackets and the connecting frames are three, and they are connected to each other in a triangular manner. The triangular structure is very stable mechanically because it can disperse and resist forces from all directions, thereby ensuring that the jack will not tip over or deform when bearing a heavy object.
[0011] Preferably, a first connecting groove is provided on the surface of the connecting frame, and the first ring is movably connected in the first connecting groove provided on the surface of the connecting frame.
[0012] Furthermore, a first connecting groove is provided on the connecting frame for accommodating and fixing the first ring, so that the first ring can rotate or move within a certain range to adapt to different fixing requirements. At the same time, it also ensures a firm connection between the first ring and the connecting frame to prevent it from falling off or loosening during use.
[0013] Preferably, a second connecting groove is provided at one end of the latch, and the second ring is movably connected in the second connecting groove provided at one end of the latch.
[0014] Furthermore, the latch serves as a locking component, and one end of the latch is designed with a second connecting groove for movably connecting with the second ring, so that when the latch is inserted into the through holes of the outer tube and the lifting column, it can remain connected with the second ring at the same time. In this way, when the latch is fully inserted and locked, the second ring is also firmly fixed in place, thereby enhancing the overall stability and reliability of the fixing mechanism.
[0015] Preferably, the adjustment mechanism comprises a lifting column, a lifting platform is fixedly connected to the top of the lifting column, and an anti-slip pad is arranged on the top of the lifting platform.
[0016] Preferably, a slide groove is provided at the top of the outer cylinder, and the lifting column is movably connected in the slide groove provided at the top of the outer cylinder. A plurality of through holes adapted to the latch are provided on the surface of the outer cylinder and the surface of the lifting column.
[0017] Furthermore, the slide groove on the top of the outer cylinder provides a track and space for the lifting column to move up and down. At the same time, multiple through holes compatible with the latches are opened on the surfaces of the outer cylinder and the lifting column. These through holes are used to insert the latches to lock the lifting column when it reaches the required height. The insertion of the latch will prevent the lifting column from continuing to move, thereby maintaining the current height unchanged.
[0018] Preferably, one end of the latch passes through a through hole formed on the surface of the outer tube and the surface of the lifting column and extends to the outside of the outer tube.
[0019] Furthermore, one end of the latch needs to pass through the through holes on the surface of the outer tube and the lifting column, which means that the length of the latch must be long enough to pass through the through holes on these two components at the same time, ensuring that the latch can firmly lock the position of the lifting column in the outer tube. Through this penetration and extension design of the latch, the triangular jack can maintain extremely high safety and stability during the jacking process.
[0020] Compared with the prior art, the beneficial effects achieved by the utility model are:
[0021] First, the utility model places the triangular jack lifting frame under the object to be lifted, ensures that the anti-slip block at the bottom of the bracket is in close contact with the ground or supporting surface to increase stability, uses the floor jack to lift the car high enough, lifts the vehicle to a certain height and position as required, and then places the triangular jack lifting frame under the vehicle to be lifted, passes one end of the pin through the through holes on the outer cylinder and the lifting column to ensure the stability and safety of the fixing mechanism, rotates or operates the lifting column to move up and down in the slide groove at the top of the outer cylinder, and adjusts the height of the lifting platform according to actual needs. When the required height is reached, uses the pin to pass through the corresponding through hole to fix the lifting column and the outer cylinder together to prevent them from sliding down on their own, places the object to be supported or lifted on the lifting platform, and the design of the anti-slip pad helps to increase friction and prevent the object from sliding. The user can easily adjust the support height to meet the support needs in different scenarios. BRIEF DESCRIPTION OF THE DRAWINGS
