Detailed Description
Example 1
As shown in fig. 1 to 3, the present utility model discloses a spring elastic force adjusting device on a door closer, which adopts the technical scheme that a spring adjusting seat 8 is installed outside a central shaft 10, a cylinder 81 is fixed at the upper end of the spring adjusting seat 8, threads are arranged outside the cylinder 81, a spring adjusting nut 11 is installed outside the cylinder 81 through threads, a pressure spring 9 is positioned above the spring adjusting nut 11, a stop screw installation slot 3 and a tool insertion slot 2 are respectively arranged on the outer side surface of the spring adjusting seat 8, a cylinder barrel 1 is arranged outside the spring adjusting seat 8, the stop screw installation slot 3 and the tool insertion slot 2 are exposed outside through a notch 5 on the cylinder barrel 1, a stop screw 7 is installed in the stop screw installation slot 3, a first bearing 6 is arranged between the lower part of the spring adjusting seat 8 and the central shaft 10, a support 4 is arranged below the spring adjusting seat 8, and a second bearing 13 is installed between the support 4 and the central shaft 10.
A gasket 12 is arranged between the outer wall of the spring adjusting nut 11 and the inner wall of the cylinder 1. The washer 12 has the function of increasing the friction between the spring adjusting nut 11 and the cylinder 1, when the spring adjusting seat 8 is shifted, the spring adjusting nut 11 is against the friction between the spring adjusting nut and the cylinder 1, and the friction is increased under the pressure of the pressure spring 9, so that the spring adjusting nut 11 does not rotate along with the spring adjusting seat 8, but moves up and down under the action of the threads.
The first bearing 6 is a planar thrust bearing, and the second bearing 13 is a tapered roller bearing.
The working principle of the utility model is as follows: when in use, the installation mode of the spring elastic force adjusting device is the same as that of the existing corresponding spring structure. The tool insertion slot 2 may have two or more rows. At ordinary times, the stop screw mounting slot 3 is internally arranged in the stop screw 7, and the outer end of the stop screw 7 is higher than the outer wall of the spring adjusting seat 8, so that the spring adjusting seat 8 can be blocked and prevented from rotating. When the spring force is adjusted, the stop screw 7 is firstly rotated to move inwards, the column spring adjusting seat 8 is not blocked, then an adjusting tool, such as a spanner with a protruding head, is inserted into the tool inserting slot hole 2, then the spring adjusting seat 8 is driven to rotate clockwise by the tool, the screw thread on the cylinder 81 at the upper end of the spring adjusting seat 8 drives the spring adjusting nut 11 to move upwards, so that the pressure spring 9 is extruded, and the spring force of the pressure spring 9 is increased. The door closer has a greater door closing force and a faster door closing speed. After the spring force is adjusted in place, the adjusting tool is removed, the stop screw 7 is rotated again to extend outwards, and the spring adjusting seat 8 is blocked again by the cylinder 1. Typically, the stop screw 7 protrudes 1-3mm from the outer wall of the spring adjustment seat 8. When the spring force adjustment is reduced, the spring adjustment seat 8 is rotated reversely.
The mechanical connection according to the utility model is a customary practice adopted by the person skilled in the art, and the technical teaching can be obtained by a limited number of tests, which belongs to the common general knowledge.
The components not described in detail herein are prior art.
Although the specific embodiments of the present utility model have been described in detail, the present utility model is not limited to the above embodiments, and various changes and modifications without inventive labor may be made within the scope of the present utility model without departing from the spirit of the present utility model, which is within the scope of the present utility model.
