Description

Technical Field

[0001] The utility model relates to an adjustable upward flip door support, in particular to an adjustable upward flip door support with double springs. Background Art

[0002] The up-flip door supports currently on the market all use springs and hydraulic buffers as power, and the folding arms and the power unit are connected and transmitted using a direct connection structure. When adjusting the power, the size of the hydraulic oil circuit is mainly controlled by the adjusting needle of the hydraulic buffer device. Since the size of the adjustment oil circuit is subject to design limitations, the structure will be more complicated when designing a large adjustment range. Therefore, it is generally not used in hydraulic buffer devices of small products such as up-flip door supports, which makes the adjustment of the up-flip door support not flexible and convenient. In addition, the folding arm and the power unit are directly connected, which is prone to cause component wear during the long-term use of the up-flip door support. Summary of the invention

[0003] The purpose of the utility model is to provide an adjustable flip-up door support, which adopts a hydraulic buffer and a flip-up thrust device to work separately and independently, so that the travel force distance adjustment and the buffer force adjustment of the folding arm can be adjusted independently, providing a more convenient and flexible adjustment method for the adjustment and installation of the flip-up door support.

[0004] The technical solution of the utility model is a shell, a folding arm, an arm-folding pulley, a supporting pulley, a supporting seat, an upward-turning thrust device, and a hydraulic buffer. The utility model is characterized in that the upward-turning thrust device is installed at the bottom of the shell, the pushing head at the top of the arm-folding thrust device can be telescoped up and down, the supporting seat is installed in the shell and is located above the upward-turning thrust device, the left end of the supporting seat is hinged to the inside of the shell, the right end bottom of the supporting seat is hinged to the pushing head of the upward-turning thrust device, the supporting pulley is installed at the middle of the top of the supporting seat, the tail section of the folding arm is hingedly installed in the shell and is located above the supporting seat, the arm-folding pulley is installed at the bottom of the tail section of the folding arm, the arm-folding pulley is opposite to the supporting pulley up and down, and the arm-folding pulley and the supporting pulley are in contact with each other when the folding arm is in a folding action, and the right end of the supporting seat is forced to swing downward.

[0005] The support seat described in the utility model is composed of a seat body, an adjusting screw and an adjusting head. The supporting pulley is installed in the middle of the top of the seat body. The left end of the seat body is hinged to the outer shell. An open groove is arranged at the bottom of the right end of the seat body. An adjusting screw is arranged in the open groove. The adjusting head is installed on the adjusting screw through a thread. Rotating the adjusting rod can make the adjusting head move left and right. The adjusting head is hinged to the pushing head of the upward thrust device.

[0006] The upward turning thrust device of the utility model is composed of a push head, a spring and a fixing seat. The fixing seat is installed at the bottom of the shell. The left and right ends of the bottom of the push head are respectively provided with springs, and the bottom end of the push head and the spring are inserted into the fixing seat.

[0007] The working principle of the folding arm and the support seat of the utility model is that the folding arm pulley and the support pulley are contacted for transmission, so that the mechanical friction between the folding arm and the support seat is minimized when working, and the adjusting screw of the rotating support seat drives the adjusting head to move, so that the hinged position of the adjusting head and the push head on the top of the upward thrust device moves, thereby adjusting the contact distance between the folding arm pulley and the support pulley to complete the adjustment. When the folding arm reaches a certain folding range during folding, it starts to be stressed, thereby making the hydraulic buffer and the folding arm adjustment independent, making the upward flip door support adjustment more flexible.

[0008] The utility model has the advantages of simple structure, stable operation, flexible and fast adjustment and long service life. BRIEF DESCRIPTION OF THE DRAWINGS
