Adjustable device used for being connected with floor spring

Abstract

The invention relates to an adjustable device used for being connected with a floor spring. The adjustable device is arranged on a foundation and comprises a horizontal position adjustment unit and an angle adjustment unit, wherein the horizontal position adjustment unit comprises an installation base and a sliding unit combined with the installation base, and the installation base and the sliding unit relatively slide in the horizontal plane so that a rotating shaft of the floor spring can move forward, backward, leftward and rightward relative to the foundation. The angle adjustment unit is combined with the horizontal adjustment unit, the rotating shaft of the floor spring is arranged on the adjustable device, and therefore the rotation angle of the axis of the rotating shaft of the floor spring can be adjusted. According to the adjustable device used for being connected with the floor spring, the floor spring is arranged on the adjustable device, and therefore vertical pivot eccentricity and front-back dislocation which are caused in the construction process can be effectively eliminated, construction convenience is greatly improved, and all-dimensional adjustment of the products in the construction process is facilitated.

Description

technical field [0001] The invention relates to the field of door closers, in particular to an adjustable device used for connecting with a floor spring. Background technique [0002] The floor spring is a hydraulic door closer, and the floor spring can be used for two-way opening of the door. Chinese invention patent 201310234570.2 discloses a pit-free double-stage speed-regulating floor spring. On the basis of ensuring the original function, it can be fixed on the ground with an adjustable base for installing the floor spring. In the actual construction and installation process, due to the imprecise operation of the construction personnel or the uneven ground, when installing the floor spring, there will be problems such as eccentricity of the upper and lower door shafts and front and rear misalignment. These problems make installation inconvenient and require strong professionalism. Existing It is difficult to overcome the current situation that the current adjustable fl...
