Description

Technical Field

[0001] The utility model relates to the technical field of floating floor installation, in particular to a floating floor damping spring shock absorber. Background Art

[0002] A floating floor is a floor system that is installed on the ground instead of being fixed directly to the ground. It is usually composed of several layers, including a bottom sound insulation pad, a middle composite wood layer or high-density fiberboard, a surface layer, etc. During the installation of the floating floor, a damping spring shock absorber needs to be fixed at its bottom to reduce vibration.

[0003] During use, the existing floating floor damping spring shock absorber performs shock absorption by installing multiple groups of damping spring shock absorbers at equal distances at the bottom of the floating floor. However, during use, the shock absorbing springs in the damping spring shock absorbers are prone to tilt during compression due to uneven force, which affects the elasticity of the springs and reduces the service life of the shock absorbers. Utility Model Content

[0005] The purpose of the utility model can be achieved by adopting the following technical solutions:

[0006] A floating floor damping spring shock absorber comprises a bottom frame, a top frame is arranged above the bottom frame, a shock absorbing mechanism is installed in the middle of the bottom end of the bottom frame, a connecting mechanism is installed in the middle of the top frame, arc grooves are symmetrically arranged on the inner side walls of the top frame, guide grooves are symmetrically opened on the inner side walls of the bottom frame, a guide mechanism is slidably connected in the guide groove, the guide mechanism comprises a sliding block slidably connected to the guide groove, a connecting rod is installed on one side of the sliding block, a guide plate is fixed at one end of the connecting rod, the outer side of the guide plate is in an inclined structure, and a ball is rollingly connected to the side of the guide plate facing the shock absorbing mechanism.

[0007] Preferably, the shock absorbing mechanism comprises a fixing seat mounted on the base frame, and a shock absorbing spring is installed in the fixing seat.

[0008] Preferably, the connecting mechanism includes a screw rod installed in the middle of the top frame, and a connecting seat is slidably connected to the outer side below the screw rod, and the connecting seat is matched with the shock-absorbing spring.

[0009] Preferably, a clamping bolt is fixed to the top of the connecting seat, and the clamping bolt is threadably connected to the screw rod.

[0010] Preferably, a limiting plate is fixed on the outer side above the screw rod, a fixing bolt is arranged above the top frame, and the fixing bolt is connected to the screw rod thread.

[0011] Preferably, shock-absorbing pads are installed at the distal ends of the bottom frame and the top frame, and the shock-absorbing pads are bonded to the bottom frame and the top frame.

[0012] Preferably, the bottom frame is in a concave shape, and the top frame is in a convex shape.

[0013] The beneficial technical effects are:

[0014] By arranging the arc groove, the guide groove and the guide mechanism, when the shock absorber is compressed, the top frame can move downward through the arc groove to press the guide plate in the guide mechanism. At this time, the guide plate is forced to move horizontally in the guide groove through the connecting rod, and then the two groups of guide plates move synchronously toward the middle. The synchronous movement of the two groups of guide plates can limit the compressed shock-absorbing spring to avoid tilting of the shock-absorbing spring when it is compressed, and the contact between the ball and the shock-absorbing spring can ensure the normal expansion and contraction of the shock-absorbing spring, thereby avoiding affecting the elasticity of the shock-absorbing spring and improving the service life of the shock absorber.
