Description

Technical Field

[0001] The utility model relates to the technical field of building aluminum alloy doors and windows, in particular to a handle fork connecting device. Background Art

[0002] In the prior art, the handle fork connection device is an important component of the window system, which is used to connect the handle and the fork to achieve the locking and opening of the window. The conventional connection method between the handle connector and the handle fork has certain defects, which are mainly reflected in the following aspects:

[0003] The overlap between the conventional handle connector and the handle fork is small. When the window sash is large or a multi-locking point design is adopted, the handle fork is subjected to a large force when the window sash is locked, which can easily cause the fork to bend and deform, affecting the normal use and life of the window. The overlap gap between the conventional handle connector and the handle fork is large, which can easily cause the handle to get stuck during the locking and opening process, affecting the customer's operating experience and the overall performance of the window.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figures 1 to 5The utility model provides a technical solution: a handle fork connecting device, including a handle fork connecting frame 1, a movable sleeve core 2 is movably inserted on the handle fork connecting frame 1, and a sleeve groove 21 is provided on the movable sleeve core 2. The sleeve groove 21 can be used for the insertion of the handle fork, and slots 12 are provided on both sides of the handle fork connecting frame 1. An extension plate 3 is slidably inserted on the slot 12, and an extension sleeve core 4 is fixedly connected to one side of the extension plate 3.

[0022] A positioning socket 31 is provided on the extension plate 3, and threaded holes 11 are provided on both sides of the handle fork connecting frame 1. A top screw 5 is screwed on the threaded hole 11, and the end of the top screw 5 is inserted into the positioning socket 31. The top screw 5 can be used to adjust the left and right displacement of the extension sleeve 4, which is convenient for on-site installation. By screwing it on the threaded hole 11 and inserting it into the positioning socket 31, the extension plate 3 and the handle fork connecting frame 1 are fixedly connected.

[0023] Both sides of the movable sleeve core 2 are extended and adapted to the frame of the handle fork connecting frame 1. Both sides of the movable sleeve core 2 are provided with through grooves 22, and the ends of the extension plates 3 are slidably inserted into the through grooves 22 to achieve the positioning of the extension plates 3 on both sides and the movable sleeve core 2.

[0024] The end of the extension plate 3 is fixedly connected with a support spring 6, and the model and specifications of the support spring 6 can be selected according to the actual working conditions. The end of the support spring 6 is fixedly connected with a clamping block 7, which has a "T"-shaped block structure and an inclined surface structure on one side of the end. The clamping block 7 is inserted into the through groove 22, and the end of the clamping block 7 extends to the inside of the sleeve groove 21.

[0025] The handle fork is not shown in the attached drawings, and predetermined grooves are provided on both sides of its end. The handle fork is inserted into the sleeve groove 21, and the end face of the handle fork squeezes the end inclined surface of the block 7, so that the end of the block 7 can be accommodated in the slot 12. When the end of the block 7 corresponds to the predetermined groove, due to the elastic force of the support spring 6, the end of the block 7 is inserted into the corresponding predetermined groove, thereby realizing the clamping connection between the entire handle connector and the handle fork, which is convenient for the rapid installation of the entire handle connector and the handle fork.
