Description

Technical Field

[0001] The present application relates to the technical field of handles, and in particular to a handle adjustment mechanism. Background Art

[0002] Handles are needed in many structures or occasions. The handles of doors and windows are generally fixed because there is more space for people to grasp.

[0003] If a handle is installed on the lamp to make it easier for people to hold the lamp, when the lamp is placed in some narrow spaces, the handle on the lamp will also take up some space. In an irregular space, the handle and the lamp may not fit together. If the angle of the handle can be adjusted so that the handle and other items are staggered, it will be convenient to place the lamp.

[0004] The existing handle adjustment mechanism includes a handle and a rotating rod rotatably connected to the handle. The rotating rod is fixed on the lighting lamp. There is a large friction between the handle and the rotating rod, so that the handle does not rotate easily. When the handle needs to be rotated, just turn it hard.

[0005] With respect to the above-mentioned related technologies, when turning the handle with force, if the operating space is limited, it is difficult for the human hand to exert force. Utility Model Content

[0006] In order to facilitate people to adjust the handle angle, the present application provides a handle adjustment mechanism.

[0007] The present application provides a handle adjustment mechanism, which adopts the following technical solution:

[0008] A handle adjustment mechanism, comprising a mounting rod plugged into the handle, the handle being provided with a through hole for the mounting rod to be plugged into, the handle being slidably mounted on the mounting rod, the mounting rod being provided with a sliding unlocking assembly, the handle being rotated or fixed on the mounting rod through the sliding unlocking assembly;

[0009] The sliding unlocking assembly includes a gear coaxially arranged with the mounting rod, and a tooth block arranged in the through hole, the tooth blocks are evenly spaced along the inner wall of the through hole, and a spacing is left between the tooth blocks for accommodating the gear teeth of the gear. The sliding unlocking assembly also includes an elastic member for driving the gear and the tooth block to cooperate.

[0010] By adopting the above technical solution, the handle is unlocked or fixed by sliding on the mounting rod. After the handle is unlocked, it can be rotated on the mounting rod at will, which saves people effort when adjusting the angle of the handle and can better apply force in a relatively narrow space. The matching stroke of the gear and the tooth block is short, so the sliding stroke of the handle is also short, and not much adjustment space is required. When the handle needs to be fixed, the handle is slid to make the gear fit between the two tooth blocks, and the handle is in a fixed state.

[0011] Optionally, the elastic member is a compression spring.

[0012] By adopting the above technical solution and using a compression spring as an elastic member, the necessary preload force is effectively provided for the cooperation between the gear and the tooth block. This design is simple and practical, and can ensure that the gear and the tooth block have sufficient friction when they cooperate, preventing the handle from sliding on its own without the action of external force, thereby further enhancing the stability and reliability of the handle adjustment mechanism.

[0013] Optionally, a mounting groove is provided on a side of the handle facing away from the mounting rod, a compression spring is located in the mounting groove, one end of the mounting rod is inserted into the mounting groove, one end of the compression spring abuts against the handle, and the other end of the compression spring abuts against the mounting rod.

[0014] By adopting the above technical solution, a mounting groove is opened on the side of the handle away from the mounting rod, and the compression spring is placed therein, so that the internal space of the handle is fully utilized and the arrangement of the compression spring is made more compact and reasonable. At the same time, this layout is also convenient for installation and disassembly, reducing maintenance costs.

[0015] Optionally, the mounting rod includes a connecting rod and a main rod that are detachably connected, and the connecting rod is located in the mounting groove.

[0016] By adopting the above technical solution, the connecting rod and the main rod are detachably connected. If the compression spring needs to be replaced, the connecting rod can be directly removed to replace the compression spring.

[0017] Optionally, the connecting rod and the main rod are threadedly connected.

[0018] By adopting the above technical solution, the connecting rod and the main rod are connected by threads. This connection method is not only firm but also easy to disassemble and assemble.

[0019] Optionally, the connecting rod is provided with a step surface, and the step surface abuts against the end of the main rod.

[0020] By adopting the above technical solution, a step surface is provided on the connecting rod and abuts against the end of the main rod. This design effectively prevents excessive rotation or dislocation of the connecting rod and the main rod during the connection process.

[0021] Optionally, one end of the mounting rod extending out of the handle is provided with an external thread.

[0022] By adopting the above technical solution, an end of the mounting rod extending out of the handle is provided with an external thread. This design enables the mounting rod to be fixed to other devices or components by means of threaded connection.

[0023] Optionally, a rotating wheel extends from the lower end surface of the gear, and part of the rotating wheel is located outside the handle.

[0024] By adopting the above technical solution, a rotating wheel is extended from the lower end surface of the gear, so that the user can disassemble the mounting rod through the rotating wheel.

[0025] In summary, the present application includes at least one of the following beneficial effects:

[0026] 1. The sliding unlocking assembly is used to realize the flexible rotation and fixation of the handle on the mounting rod through the cooperation of the gear and the tooth block. If the handle is installed on the lighting lamp, it can meet the requirements of the position and angle of the handle in different usage scenarios of the lighting lamp;

[0027] 2. A compression spring is used as an elastic member, and its elastic force is used to drive the gear and the tooth block to cooperate closely, thereby ensuring the stability of the handle in a rotating or fixed state, while simplifying the structure and reducing the manufacturing cost.

[0035] The following is combined with Figure 1-6 This application is described in further detail.

[0036] The present application embodiment discloses a handle adjustment mechanism. Figure 1 and Figure 2 A handle adjustment mechanism includes a mounting rod 1, a through hole 21 for inserting the mounting rod 1 is provided on one end of a handle 2, the mounting rod 1 is inserted on the handle 2, and the handle 2 can slide back and forth along the axial direction of the mounting rod 1 through the through hole 21. The other end of the handle 2 away from the mounting rod 1 is a hand-held portion, and a sliding unlocking component 3 is provided on the mounting rod 1. After a person holds the hand-held portion of the handle 2, the handle 2 can be selectively rotated or fixed relative to the mounting rod 1 through the sliding unlocking component 3.

[0037] Reference Figure 2 and Figure 3 Specifically, the sliding unlocking assembly 3 includes a gear 31 coaxially arranged with the mounting rod 1, and a tooth block 32 arranged on the inner wall of the through hole 21 of the handle 2 for meshing with the gear 31. The tooth blocks 32 are evenly spaced along the inner peripheral side wall of the through hole 21 of the handle 2, and a spacing is left between two adjacent tooth blocks 32 for the gear teeth of the gear 31 to be inserted.

[0038] Reference Figure 4 In addition, the sliding unlocking assembly 3 is also equipped with an elastic member 33 for ensuring that the gear 31 and the tooth block 32 remain in meshing state.

[0039] The gear teeth on the gear 31 and the tooth blocks 32 are both provided with smooth chamfers, so that the gear teeth on the gear 31 can be easily inserted between the two tooth blocks 32 no matter how the handle 2 is rotated.

[0040] The gear 31 is made of plastic injection molding, and the mounting rod 1 is made of metal material. The mounting rod 1 is placed in the gear 31 injection mold, and the gear 31 is directly fixed on the mounting rod 1 by injection molding, thereby improving the connection strength between the gear 31 and the mounting rod 1.

[0041] Reference Figure 4 In this embodiment, the elastic member 33 is preferably a compression spring. The compression spring has good elasticity and recovery, and can ensure stable cooperation between the gear 31 and the tooth block 32. At the same time, the compression spring is low in cost, easy to obtain and replace, and further reduces the maintenance cost of the handle 2 adjustment mechanism.

[0042] Reference Figure 4 and Figure 5A mounting groove 22 is provided on the side of the handle 2 facing away from the mounting rod 1, and the compression spring is located in the mounting groove 22. The mounting rod 1 includes a main rod 12 and a connecting rod 11 that are detachably connected, wherein the connecting rod 11 is located in the mounting groove 22. An end cap is fixedly connected to one end of the connecting rod 11, one end of the compression spring abuts against the handle 2, and the other end abuts against the end cap, and the compression spring is also sleeved on the connecting rod 11. This arrangement enables the compression spring to stably provide the required elastic force without affecting the normal use of the handle 2, thereby ensuring the reliable matching of the gear 31 and the tooth block 32.

[0043] The split design of the mounting rod 1 is not only convenient for installation and disassembly, but also convenient for replacing the connecting rod 11 of different lengths according to actual needs to meet the needs of different usage scenarios. It is also convenient for replacing the compression spring. If the compression spring is aged or the elastic force is weakened, the connecting rod 11 can be directly disassembled for replacement, and the main rod 12 does not need to be removed from the equipment. At the same time, the connecting rod 11 and the main rod 12 are connected by threads, which further enhances the stability of the structure and the reliability of the connection.

[0044] Reference Figure 4 and Figure 6 In this embodiment, the structure of the connecting rod 11 is further improved. The connecting rod 11 is provided with a step surface 111, and the step surface 111 abuts against the end of the main rod 12. The design of the step surface 111 can ensure that the connecting rod 11 and the main rod 12 can be accurately aligned when connected, and the connecting rod 11 does not over-compress the compression spring.

[0045] Reference Figure 5 One end of the mounting rod 1 extending from the handle 2 is provided with an external thread, so that when the mounting rod 1 is mounted on a lighting lamp or other external equipment, it is convenient to install and remove the mounting rod 1.

[0046] Reference Figure 4 and Figure 5 , the rotating wheel 4 extends from the lower end surface of the gear 31, and the gear 31 and the rotating wheel 4 are integrally injection molded. The rotating wheel 4 is partially located outside the handle 2, and the outer diameter of the portion of the rotating wheel 4 located outside the handle 2 is larger. The portion of the rotating wheel 4 located outside the handle 2 is a rotating portion 41, and the outer peripheral side of the rotating portion 41 is provided with anti-slip grooves 42. The entire mounting rod 1 can also be rotated by the rotating portion 41, which is convenient for disassembly of the mounting rod 1. When the gear 31 and the tooth block 32 are matched, one end surface of the through hole 21 of the handle 2 abuts against the rotating portion 41. The rotating wheel 4 can also limit the handle 2, limiting excessive sliding and disengagement from the gear 31 when the handle 2 is reset in the direction of the gear 31.

[0047] An implementation principle of a handle adjustment mechanism in an embodiment of the present application.

[0048] Under normal conditions, due to the action of the elastic member 33, the gear 31 and the tooth block 32 are in meshing state, and the handle 2 is fixed relative to the mounting rod 1 and cannot rotate. When the user needs to adjust the angle of the handle 2, the user grabs the hand-held portion of the handle 2, places the thumb on the end cap of the connecting rod 11, and slides the handle 2 upward to squeeze the elastic member 33, causing the gear 31 to disengage from the tooth block 32, and the handle 2 can now rotate freely relative to the mounting rod 1. After the adjustment is completed, release the handle 2, and under the action of the elastic member 33, the gear 31 re-engages with the tooth block 32, and the handle 2 is fixed again at the selected position. This design is not only simple in structure, but also labor-saving in operation, and convenient for manual force, which greatly improves the user experience.

[0049] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
