Detailed Description

The present invention will be further described with reference to the accompanying drawings. A door closer with a buffer is characterized in that: it includes

base

1, and 1 both sides of base are provided with main support 2 and buffer frame 3 perpendicularly, and spiro union fixed mounting has connecting plate 4 on the buffer frame 3, and the top activity hinge of connecting plate 4 installs sliding seat 5, and last articulated pull rod 6 of installing of still of sliding seat 5, guide pulley 7 are installed to the other end of pull rod 6, and guide pulley 7 is located the guide way 8 on connecting plate 4 and slides, buffer frame 3 on the spiro union install buffering jar support 9, the cylinder body part 10 of buffer is fixed on buffering jar support 9, the piston rod part 11 of buffer is fixed on pull rod 6, pull rod 6 and base 1 within a definite time still be provided with extension spring 12, extension spring 12 is through 6 pulling sliding seat 5 of pull rod all the time to base 1 direction beat.

The base 1, the main support 2 and the buffer frame 3 are integrally formed by bending metal plates, and the three are distributed in an n shape.

The tail of the main support 2 is provided with a positioning groove 13, the head of the main support 2 is provided with a bracket 14, a positioning block 15 arranged at the tail of the connecting plate 4 is inserted in the positioning groove 13 to be fixed, and the front end of the connecting plate 4 is supported above the bracket 14.

The connecting plate 4 and the main support 2 are both provided with a first positioning hole 16, and a fixing screw or a rivet penetrates through the first positioning hole 16 to fix the two into a whole.

The buffer frame 3 and the buffer cylinder bracket 9 are provided with second positioning holes 17, and fixing screws or rivets pass through the second positioning holes 17 to fix the two into a whole.

The buffer cylinder support 9 is provided with an accommodating area 18, the accommodating area 18 is formed by bending and enclosing a body material of the buffer cylinder support 9, and the cylinder body part 10 of the buffer is fixed in the accommodating area 18.

The pull rod 6 is provided with a plurality of spring holes 19 which are longitudinally distributed, one end of the tension spring 12 is hooked in the spring holes 19, and the other end is hooked on the base 1 according to the requirement of elasticity.

The working principle is as follows: in the present application, the door closer is installed on an oven as an example, when the door closer is used, the base portion is fixed on the box body, the movable seat portion is installed on the box door, and the door closer is generally installed in pairs left and right for use.

When the box door is closed, the movable seat rotates around a hinged point between the movable seat and the connecting plate, and the closing of the box door is realized. In the present case, in order to realize that the chamber door self-closing, and have certain pressure of closing the door after closing and keep the chamber door closed state, still articulated pull rod 6 of installing on sliding seat 5 in the present case, guide pulley 7 is installed to the other end of pull rod 6, and guide pulley 7 is located the guide way 8 on connecting plate 4 and slides.
