Abstract
Description
Technical Field
[0001] This utility model relates to the field of handle technology, and in particular to an improved handle structure. Background Technology
[0002] Mortise locks, as one of the most widely used types of door locks on the market, typically consist of three parts: a handle, a lock cylinder, and a lock body. Due to their structural stability and security, they are widely installed on various types of doors, including interior doors and security doors, and are a core component for door opening and closing control in both residential and commercial settings. As the door and window industry continues to demand higher assembly efficiency and cost control, the traditional assembly methods for mortise lock handles and door core strips, due to their cumbersome processes and high requirements for component compatibility, are gradually becoming insufficient to meet the needs of mass production and rapid installation. Therefore, quick-installation designs for handles and door core strips have become an important direction for technological improvement in the industry. To address the pain points of traditional assembly, optimized solutions for quick-installation handle structures have emerged in existing technologies. For example, Chinese Utility Model Patent No. CN217080022U discloses a quick-installation structure for handles and door / window handles. Through the cooperation between the locking part of the elastic locking member and the tapered adjustment part, the door core strip is locked. At the same time, it solves the problems of needing to process the door core strip and identify the direction when assembling the door core strip in existing technologies, thereby further improving the assembly efficiency of the handle and reducing the cost of the handle.
[0003] However, the existing quick-release structure still has the following drawbacks in practical applications: 1. In this quick-release structure, the elastic locking element needs to be equipped with at least one locking part, and the locking part needs to be precisely matched with the tapered adjustment part of the inner cavity of the guide mounting sleeve. This results in a complex structure and high processing difficulty, leading to high production costs for the parts and hindering large-scale mass production; 2. When disassembling, the flat end needs to be inserted into the disassembly hole and applied to the locking part. By pressing on the locking part, the locking part is unlocked from the door core strip. The principle is to use the tapered surface of the locking part to decompose the pressure applied to it into a thrust that forces the elastic locking element to move inward, thereby overcoming the elasticity of the element and unlocking it. However, in this process, the decomposition efficiency of pressure into thrust is low, and the actual thrust that can drive the elastic locking element to move is small, resulting in the user needing to apply a large amount of pressure to complete the unlocking operation, thus causing inconvenience in operation. Utility Model Content
[0004] The purpose of this invention is to provide a handle with an improved structure to solve the problems mentioned in the background art.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an improved handle, including a handle tube body, a sleeve sleeved inside the handle tube body, a handle head provided at the bottom end of the sleeve sleeve, and the handle head inserted and fixed to the handle tube body. A guide hole is provided on the handle head, a door core strip is sleeved in the guide hole, a stop block is sleeved on the door core strip, and the stop block is fixedly connected to the sleeve sleeve. A locking block is provided at the top end of the handle head, a locking hole is provided on the locking block at the position corresponding to the door core strip, and the door core strip is sleeved in the locking hole. A support block is fixedly connected to the lower surface of the locking block. A positioning groove is provided on the handle head at the position corresponding to the support block, and the support block is set in the positioning groove. An inclined surface is provided on the upper surface of the locking block. A spring is sleeved on the door core strip, with one end of the spring set on the inclined surface and the other end set on the stop block.
[0006] Preferably, a second through hole is provided on the sleeve at the position corresponding to the locking block, and a first through hole is provided on the handle tube at the position corresponding to the second through hole.
[0007] Preferably, the handle head has a first groove, and the sleeve is inserted and fixed in the first groove.
[0008] Preferably, a flange is fixedly connected to the handle head, and the flange is located at the bottom end of the handle tube.
[0009] Preferably, the stop block has a second groove, and one end of the spring is disposed in the second groove.
[0010] Preferably, the stop block has a limiting hole, and the door core strip is sleeved in the limiting hole.
[0011] The improved handle provided by this utility model has the following advantages: This utility model applies elastic force to the locking block through a spring, causing the locking block to deflect around the support block as a fulcrum, and achieves stable locking of the door core strip with the help of the locking hole. The locking block has a simple structure and low requirements for processing precision, which can effectively reduce the cost of parts; when disassembling the door core strip, no large pressure is required. Only a tool is needed to directly push the locking block through the through hole to make it deflect around the support block to unlock. The operation is simple and labor-saving, while taking into account the locking reliability and ease of use, and is more suitable for the actual production and maintenance needs of mortise lock handles.

[0018] Please see the appendix Figure 1 -Appendix Figure 3This utility model provides an embodiment of an improved handle, comprising a handle tube 1, a sleeve 2 fitted inside the handle tube 1, a handle head 3 at the bottom end of the sleeve 2, and the handle head 3 being inserted and fixed to the handle tube 1. A guide hole 32 is provided on the handle head 3, a door core strip 7 is fitted inside the guide hole 32, a stop block 6 is fitted on the door core strip 7, and the stop block 6 is fixedly connected inside the sleeve 2. A locking block 4 is provided at the top end of the handle head 3, and a locking hole 41 is provided on the locking block 4 at a position corresponding to the door core strip 7. 7 is fitted into the locking hole 41. A support block 42 is fixedly connected to the lower surface of the locking block 4. A positioning groove 34 is opened on the handle head 3 at the position corresponding to the support block 42, and the support block 42 is set in the positioning groove 34. An inclined surface 43 is provided on the upper surface of the locking block 4. A spring 5 is fitted onto the door core strip 7, with one end of the spring 5 set on the inclined surface 43 and the other end set on the stop block 6. The tube sleeve 2 is used to accommodate the handle head 3, the locking block 4, the spring 5 and the stop block 6. The handle head 3 guides the door core strip 7 through the guide hole 32. The stop block 6 The spring 5 and the door core strip 7 are used to limit the movement of the spring 5 and the door core strip 7. The spring 5 acts on the inclined surface 43 to provide a reset force for the locking block 4. The support block 42 is the fulcrum for the deflection of the locking block 4. The positioning groove 34 is used to accommodate the support block 42. A second through hole 21 is opened on the sleeve 2 at the position corresponding to the locking block 4. A first through hole 11 is opened on the handle tube 1 at the position corresponding to the second through hole 21. The second through hole 21 and the first through hole 11 serve as disassembly holes to accommodate disassembly tools. A first stepped groove 33 is opened on the handle head 3, and the sleeve 2 is inserted and fixed. The first groove 33 is fixed in the first groove 33, which is used to accommodate the sleeve 2; a flange 31 is fixedly connected to the handle head 3, and the flange 31 is set at the bottom end of the handle tube 1. The flange 31 is used to limit the handle head 3 during the insertion of the handle tube 1; a second groove 62 is opened on the stop block 6, and one end of the spring 5 is set in the second groove 62, which is used to accommodate the spring 5; a limiting hole 61 is opened on the stop block 6, and the door core strip 7 is sleeved in the limiting hole 61, which is used to limit the door core strip 7.
[0019] Working principle: When using this utility model, the stop block 6 is installed inside the sleeve 2, and the spring 5, locking block 4, and handle head 3 are sequentially installed into the sleeve 2, so that one end of the spring 5 abuts in the second groove 62 and the other end abuts on the inclined surface 43. The support block 42 is installed in the positioning groove 34, and the sleeve 2 is installed in the first groove 33 of the handle head 3, thus completing the assembly of the quick-release assembly. Then, the assembled quick-release assembly is installed into the handle tube 1 until it is blocked by the flange 31, and the first through hole 11 is aligned with the second through hole 21. Then, the door core strip 7 is inserted into the guide hole 32, and the door core strip 7 will push the locking block 4, which in turn supports the block 4. 2 is the pivot point for deflection, and the spring 5 is compressed. When the locking hole 41 is deflected to the horizontal state, it is aligned with the end of the door core strip 7. The door core strip 7 passes through the locking hole 41 until it is blocked by the limiting hole 61. Under the action of the spring 5, the locking block 4 presses tightly against the door core strip 7 through the locking hole 41, thereby locking the door core strip 7. If it is necessary to remove the door core strip 7, a tool with a diameter smaller than the diameter of the first through hole 11, such as a flathead screwdriver, can be used. Insert the flathead screwdriver into the second through hole 21 through the first through hole 11 and push the locking block 4. The locking block 4 deflects with the support block 42 as the pivot point, and the locking hole 41 deflects accordingly and is no longer pressed tightly against the door core strip 7, so the door core strip 7 can be removed.
