Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Refer to fig. 1 to 2. Novel exempt from to dig formula window closer, including main part 1, rotating device 2 and support arm 3, support arm 3 rotates with main part 1 through rotating device 2 and is connected, and main part 1 is square pipe, and support arm 3 is located one side of main part 1, and the one end of main part 1 is equipped with tail-hood 4, and the outside of tail-hood 4 is equipped with mounting hole 41, and mounting hole 41 is located the outside of main part 1, and tail-hood 4 is connected for rotating with main part 1. During actual installation, the installation direction of the main body 1 is adjusted according to the opening direction of the window sash; if the window sash is opened leftwards, the tail cover 4 is rotated, so that the mounting hole 41 is rotated to one side of the window frame and is locked by penetrating through the mounting hole through a screw, and the main body 1 and the window frame are locked and fixed; if the casement opens to the right, the window closer is overturned for the direction of support arm 3 is the same as the installation direction of the window frame, then tail-hood 4 is rotated, the position of installation hole 41 is adjusted, and the rotation is to one side of the window frame, the installation hole is penetrated through by a screw to lock, and the locking and fixing of main body 1 and the window frame are realized. Therefore, when the window sash is integrally installed, the window sash can adapt to window sashes in different installation directions, products in different installation directions do not need to be distinguished, and the universality of the whole window sash is greatly improved. Wherein, the support arm 3 is fixedly connected with the window sash, and the window sash rotates to drive the support arm to rotate.

One end of tail-hood 4 is equipped with connecting rod 42, and connecting rod 42 is equipped with on the connecting rod 42 and rotates the groove 43 in stretching into main part 1, and the inner wall of main part 1 is equipped with arch 11, and arch 11 cooperatees with rotating the groove 43. Wherein, the bulge 11 is formed by pressing the peripheral outer wall of the main body 1 inwards, and the bulge 11 and the main body 1 are in an integrated structure. The protrusion 11 is snapped into the rotation groove 43, so that the connection rod 42 can rotate and keep the tail cap 4 engaged with the main body 1 under the limit action of the protrusion 11.

The other end of the tail cover 4 is provided with a tail plate 44, the tail plate 44 and the tail cover 4 are of an integrated structure, the mounting hole 41 is located on the tail plate 44, and the tail plate 44 is flush with the bottom end of the tail cover 4. The four end surfaces of the tail plate 44 are respectively flush with the four corresponding end surfaces of the main body 1; therefore, when the tail cover 4 is rotated and the main body needs to be fixed on the window frame, the tail plate 44 can be flush with the corresponding side of the main body, so that the mounting hole 41 can be tightly attached to the window frame, and the locking and fixing of the screw are facilitated. Wherein, the tail plate 44, the tail cover 4 and the connecting rod 42 are of an integrated structure.

The rotating device 2 comprises a rack 21, an accommodating cavity 12 is arranged in the main body 1, the rack 21 is arranged in the accommodating cavity 12, one end of the support arm 3 is provided with a rotating tooth 31, and the rotating tooth 31 is matched with the rack 21. Wherein the accommodating chamber 12 penetrates along the length direction of the main body 1. In the actual use process, an opening is formed in the first side 11 of the main body 1, so that the rotating teeth 31 can be conveniently matched with the rack 2 after passing through the opening.

The novel excavation-free window closer further comprises a spring 5, wherein the spring 5 is arranged in the accommodating cavity 12, and one end of the spring 5 is abutted against the rack 21.

When the window frame is used, the supporting arm 3 rotates together with the window sash when the window sash is pushed to rotate by external force. When the arm 3 rotates, the rotating teeth 31 at one end of the arm 3 drive the rack 21 engaged therewith to move, so that the rack 21 moves in the accommodating cavity 11. Specifically, in the opening process of the window sash, the rack 21 matched with the rotating teeth of the support arm 3 gradually compresses the spring 5, and the moving speed of the rack 21 is reduced under the action of the rebound force of the spring 5, so that the opening speed of the window sash is reduced; on the contrary, when the window sash is closed, the rack 21 can be pushed to move reversely by the resilience of the spring 5, so that the support arm 3 can rotate reversely, and the purpose of quickly closing the window sash is achieved.

This novel exempt from to dig formula window closer still includes accent power device 6, and accent power device 6 is including accent power board 61 and accent power screw 62, and the one end at main part 1 is established to tail-hood 4 lid, and in accent power board 61 located holding chamber 12, the other end and the accent power board 61 looks butt of spring 5, and accent power screw 62 runs through behind the tail-hood 4 and transfers power board 61 looks butt.

The tail cover 4 is provided with a threaded hole, and the force adjusting screw 62 is in threaded fit with the tail cover.

Specifically, when the weight of the window sash is large or the opening speed of the window sash needs to be reduced, the force adjusting screw 53 is screwed, so that the force adjusting screw 53 moves towards one side of the spring 5, the force adjusting plate 61 is pushed to gradually press towards the spring 5, the compression degree of the spring 5 is increased, and the rebound force of the spring is favorably improved. On the contrary, when the weight of the window sash is smaller or the requirement on the opening speed of the window sash is not high, the force adjusting screw 62 is screwed reversely, and finally the compression degree of the spring is reduced and the rebound force of the spring is reduced.

One side of the main body 1 is provided with a positioning sleeve 7, one end of the support arm 3 is arranged in the positioning sleeve 7, and the rotating teeth 31 on the support arm 3 are positioned in the positioning sleeve 7. Therefore, the positioning sleeve 7 can be integrally formed with the main body 1, or fixed on one side of the positioning sleeve 7 by welding. The mounting position of the support arm 3 can be conveniently limited through the positioning sleeve 7, and the meshing of the rotary teeth and the racks is ensured; meanwhile, the rotary teeth can be protected.

The novel digging-free window closer further comprises a rivet 8, the rivet 8 is arranged on the positioning sleeve 7, and the support arm 3 is connected with the positioning sleeve 7 through the rivet 8. The rivet 8 penetrates through the support arm 3, so that the support arm 3 can rotate around the rivet 8 conveniently.

The novel digging-free window closer also comprises an end cover 9, and the end cover 9 is covered at the other end of the main body 1.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various changes and modifications can be made without departing from the inventive concept of the present invention, and these changes and modifications are all within the scope of the present invention.
