Description

Technical Field

[0001] This utility model relates to the field of lifting handle technology, specifically to a concealed lifting handle that is easy to use. Background Technology

[0002] Currently, the commonly available external lifting handles for cases on the market include normal fixed types and hinged types that automatically swing and fit the case body without external force. The hinged type further features a concealed lifting handle structure that is exposed on the surface of the case body and embedded in the case body wall. In the existing technology, this type of hinged lifting handle can swing at multiple angles during use, making it convenient for workers to lift and grip.

[0003] Existing hinged lifting handles, while capable of swinging and flipping, lack a retaining structure. After the operator releases the handle, it swings along the hinge axis and adheres to the case based on its own weight. While this design facilitates the automatic adhesion of the lifting handle when not in use, reducing its footprint and preventing deformation or damage from collisions, it also leads to inconvenience in certain situations. For example, when the operator needs to swing it up to retain it, this swinging motion can be convenient when the operator has lifted the case for too long, needs to release their grip, or needs to use external force to hook the lifting rope. Utility Model Content

[0004] The purpose of this utility model is to provide a convenient concealed lifting handle structure. By setting a limiter, it realizes the swing restriction and release of the restriction at multiple swing angles set on the lifting handle, making it easy to store and use.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a concealed lifting handle that is easy to use, including a mounting component and a handle hinged to the mounting component via a hinge shaft. The handle is provided with a limiting component, which includes a movable component, a spring, and a limiting slider. The mounting component is provided with an arc groove and a limiting groove. The limiting slider is slidably disposed between the arc groove and the limiting groove. The spring is used to drive the movable component to pop out relative to the handle and to drive the limiting slider to engage with the limiting groove.

[0006] Preferably, the movable member includes a pressure part and an extension rod, and the limiting slider is located at the end of the extension rod away from the pressure part.

[0007] Preferably, the mounting component is further provided with a hinged buckle plate, the hinged buckle plate is provided with a mounting groove, the inner wall of the mounting groove is provided with a hinge groove, the hinge shaft includes a hinge part and a mounting part, the hinge part passes through the handle from the mounting groove, and the rear end of the mounting part abuts against the hinged buckle plate.

[0008] Preferably, the mounting component is further provided with a cushioning pad, which is positioned directly opposite the handle.

[0009] Preferably, the mounting component is provided with a receiving groove, the size of the handle is matched with the receiving groove, and the mounting component is provided with a beveled part, the inclination angle of the beveled part being set relative to the maximum swing angle of the handle.

[0010] Beneficial effects: The concealed lifting handle of this utility model, through the setting of a limiting structure, allows it to swing and position itself, automatically maintaining the swing angle after swinging up. This makes it convenient for users to grip again after releasing their hand, avoiding the inconvenience caused by the common hinged lifting handles that automatically reset after losing lifting force and repeatedly resetting to fit against the box. Furthermore, this retaining structure not only maintains the swing limit of the lifting handle itself, but also automatically releases the restriction under external force greater than the automatic gravity, allowing it to swing and fit against the box, thus avoiding damage to the lifting handle caused by external impacts and collisions.

Detailed Implementation

[0016] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, where there is no conflict, the embodiments and features described in these embodiments can be combined with each other.

[0017] like Figure 1-4The illustrated concealed lifting handle includes a mounting component 1 and a handle 2 hinged to the mounting component 1 via a hinge shaft 3. The handle 2 is provided with a limiting component 4, which includes a movable component 41, a spring 42, and a limiting slider 43. The mounting component 1 is provided with an arc groove 11 and a limiting groove 12. The limiting slider 43 is slidably disposed between the arc groove 11 and the limiting groove 12. The spring 42 is used to drive the movable component 41 to pop out relative to the handle 2 and to drive the limiting slider 43 to engage with the limiting groove 12.

[0018] As a further provision of the above solution, the movable member 41 includes a pressing part 44 and an extension rod 45, and the limiting slider 43 is located at the end of the extension rod 45 away from the pressing part 44.

[0019] As a further provision of the above solution, the mounting component 1 is also provided with a hinged buckle plate 15, the hinged buckle plate 15 is provided with a mounting groove 16, the inner wall of the mounting groove 16 is provided with a hinge groove 17, the hinge shaft 3 includes a hinge part 31 and a mounting part 32, the hinge part 31 passes through the handle 2 through the mounting groove 16, and the rear end of the mounting part 32 abuts against the hinged buckle plate 15.

[0020] As a further feature of the above solution, the mounting component 1 is also provided with a buffer pad 19, which is positioned directly opposite the handle 2.

[0021] As a further feature of the above solution, the mounting component 1 is provided with a receiving groove 10, the size of the handle 2 is matched with the receiving groove 10, and the mounting component 1 is provided with a beveled surface 13, the tilt angle of the beveled surface 13 being relative to the maximum swing angle of the handle 2. Example

[0022] refer to Figure 1 The concealed pull handle of this embodiment shown has a main body including a mounting part 1 with several screw holes. The mounting part 1 is fixed to the pre-drilled slots in the box or cabinet through the screw holes. Its front is flush with the outer wall of the box, so that the main body is embedded below the surface of the box, reducing the risk of being bumped or scratched.

[0023] Further reference Figure 2 , Figure 3 and Figure 4The main body of the mounting component 1 is provided with a hinge plate 15, which is used for the installation and removal of the hinge shaft 3. The specific structure includes a mounting groove 16 below the hinge plate 15 when it is fastened, and hinge grooves 17 on both sides of the mounting groove 16. When installing, the hinge shaft 3 is inserted from the mounting groove 16, passes radially through the hinge groove 17 and the corresponding hole on the handle 2, and then the end is inserted into the hole on the mounting component 1 to complete the hinged installation of the handle 2 relative to the mounting component 1. The hinge shaft 3 is divided into a mounting part 32 and a hinge part 31. The diameter of the mounting part 32 is larger than that of the hinge groove 17 to prevent the hinge shaft 3 from coming out from the inside. The rear end is held by the hinge plate 15 which is reset by hinge swing. The hinge shaft 3 can be easily installed before the hinge plate 15 is given a swing force. The hinge plate 15 can be used to maintain a normally closed state by means of magnetic attraction or interference fit.

[0024] Further reference Figure 2 As shown, the mounting part 1 is also provided with an arc groove 11 and a limiting groove 12. It is worth noting that the handle 2 is also provided with a limiting part 4. The limiting part 4 is composed of a movable part 41 located inside it and a spring 42 located in the inner cavity of the handle 2 that pushes the movable part 41 to slide outward. A limiting slider 43 is also provided at the end of the movable part 41. When the user lifts the handle 2 outward, the movable part 41 is pressed into the handle 2. At this time, the spring 42 is in a compressed state. At the same time, the limiting slider 43 enters the arc groove 11 from the limiting groove 12. The handle 2 swings relative to the mounting part 1. When the user releases it, the handle 2 will swing downward and reset with its own weight.

[0025] However, after the above swing, if the swing angle is appropriate, the spring 42 will elastically reset upon release, driving the movable part 41 to extend outward. When the radial groove 11 is provided at the current position of the limiting slider 43, the limiting slider 43 will be driven by the extension of the movable part 41, and then enter the limiting groove 12 from the groove 11. Once it enters the limiting groove 12, it will cooperate with the hinge shaft 3 to limit the swing of the handle 2, thereby forming a swing holding. That is, when it swings to a certain position, the limiting part 4 will prevent the handle 2 from falling due to its own weight, thus forming a swing holding. It is worth noting that the spring 42 needs to have a certain strength to allow the movable part 41 to extend quickly, but the elastic force should not be too large. If it is too large, it will easily make it difficult for the limiting slider 43 to enter the groove 11 during use.

[0026] Furthermore, it is worth noting that in this embodiment, the limiting slider 43 is fitted onto a rotating rod extending from the side of the extension rod 45 of the movable member 41, so that its cooperation with the limiting groove 12 has a certain degree of mobility. The purpose of this design is that when the handle 2 is in the swinging use state, if the user temporarily releases it, the handle 2 will be held in place by the spring 42, so that it will not swing back under its own weight. However, once an external force is involved, such as a collision, if the collision force is greater than its holding force, the limiting slider 43 will slide under the pressure of the external force, and react on the movable member 41, thereby compressing the spring 42 and causing the limiting slider 43 to roll into the arc groove 11. The handle 2 will swing back to the receiving groove 10 to fit against the box for storage, which not only ensures the swinging and holding, but also protects the handle 2 from damage such as collisions, and is convenient to use.

[0027] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of this utility model and its equivalents, this utility model also intends to include these modifications and variations.
