DETAILED DESCRIPTION

[0027] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] See also Figure 1-6 As shown, the utility model is a combined multi-purpose door handle, comprising a fixed core 1, and a block 2 is provided on the surface of the fixed core 1. A connecting rod 3 is detachably provided on the surface of the fixed core 1 through the block 2. The shape of the connecting rod 3 is L-shaped, and two connecting rods 3 are provided on the surface of the square fixed core 1. A sliding groove 31 is provided on the surface of each connecting rod 3. The shape and position of the sliding groove 31 are adapted to the blocks 2 on both sides of the fixed core 1. A threaded hole 32 is provided at one end of the connecting rod 3, and the setting direction of the threaded hole 32 is parallel to the direction of the setting end. A threaded through hole 33 is provided at the other end of the connecting rod 3, and the direction of the threaded through hole 33 is perpendicular to the direction of the setting end. The threaded through hole 33 is opened on both sides of the connecting rod 3. A first positioning hole 34 is provided at one end of the connecting rod 3 where the threaded through hole 33 is provided, and the first positioning hole 34 is parallel to the nearby threaded through hole 33.

[0029] The end of the connecting rod 3 with the threaded through hole 33 is detachably mounted with a handle structure 4. A connecting end 43 is fixedly mounted on the bottom of the handle body 41 of the handle structure 4, with a buffer groove 42 disposed between the handle body 41 and the connecting end 43. A second positioning hole 44 is disposed on the outer surface of the connecting end 43, oriented perpendicularly to the direction of the connecting end 43. The connecting rod 3 and the handle structure 4 are secured together by a connector 5. A positioning end 51 is fixedly mounted on the surface of the connector 5, and its shape corresponds to the shapes of the first and second positioning holes 34 and 44. A positioning platform 52 is positioned in the middle of the connector 5, which is higher than the connector 5 and has a mounting hole 53 defined on its surface. The connector 5 can be connected to the handle structure 4 and the connecting rod 3 via the connecting end 43. The mounting hole 53 of the positioning platform 52 in the middle of the connector 5 coincides with the threaded through hole 33 of the connecting rod 3. Fixing bolts 6 are then installed in the mounting hole 53 and the threaded through hole 33 for reinforcement.

[0030] When using this combined multi-purpose door handle, the connecting rods 3 are snap-fitted to the inner core. The number of connecting rods 3 is selected based on the weight of the door being used. When the door is too heavy and the handle is required to provide a large force, two connecting rods 3 are installed on the door core. At this point, the threaded holes 32 and threaded through-holes 33 of the two connecting rods 3 overlap, and the connecting rods 3 and handle structure 4 are fixed together via the connector 5. The positioning ends 51 of the connector 5 extend into the first positioning hole 34 and the second positioning hole 44, respectively. At this point, the setting hole 53 of the intermediate positioning platform 52 of the connector 5 overlaps with the threaded through-hole 33 of the connecting rod 3. The fixing bolt 6 is inserted into the setting hole 53, and one end of the fixing bolt 6 enters the threaded through-hole 33 and the threaded hole 32, threadedly connecting with the inner wall. The fixing bolt 6 simultaneously positions the connector 5 and the two connecting rods 3, securing the two connecting rods 3 to the surface of the fixed core 1. At the same time, the fixing bolt 6 presses the connector 5 tightly, strengthening the connection between the positioning end 51, the connecting rod 3, and the handle structure 4. The connecting member 5 is arranged on the outside of the handle structure 4 and the connecting rod 3 to facilitate the staff to install and fix it.

[0031] Working principle of the present invention: A combined multi-purpose door handle of the present invention is provided with a connecting rod 3 and a fixed core 1. The surface of the fixed core 1 is detachably provided with two connecting rods 3. The number of the connecting rods 3 can be changed according to the corresponding door type, and can be freely adjusted to achieve the effect of saving costs and convenient installation; by providing a connecting piece 5, the connecting piece 5 can position and connect the handle structure 4 and the connecting rod 3; at the same time, the setting hole 53 on the surface of the connecting piece 5 coincides with the threaded holes 32 and the threaded through holes 33 of the two connecting rods 3, so that a fixing bolt 6 is provided inside, and the fixing bolt 6 fixes the two connecting rods 3 and the connecting piece 5 at the same time; the fixing bolt 6 can press the connecting piece 5 tightly, so that the positioning end 51 presses the handle structure 4 on the inner wall of the door body for fixation.

[0032] The above describes an embodiment of the present invention in detail. However, the above content is only a preferred embodiment of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent application of the present invention.
