Description

Technical Field

[0001] This utility model relates to the field of box technology, and more specifically, to a handle and a safety box having the handle. Background Technology

[0002] Most safety cases widely used in the market are equipped with handles for easy carrying. However, existing handles generally have the following problems: First, traditional handles are usually connected to the safety case via simple pins or bolts. Under frequent lifting or impact, gaps or fatigue damage can easily develop at the connection point, affecting the handle's sturdiness and lifespan. Second, some handles can only rotate in one direction, or lack a reliable limiting structure when lifting or lowering, causing the handle to wobble and collide with the case when not in use, affecting not only the appearance but also easily wearing down structural components. Furthermore, the handle connection structure is complex, requiring additional components such as screws and spring clips for installation, making the process cumbersome and unsuitable for mass assembly or later maintenance.

[0003] Therefore, the existing safety box handles still need improvement in terms of connection stability, rotation limit, and ease of installation. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a lifting handle and a safety box with the lifting handle. The lifting handle and safety box with the lifting handle of this invention have high connection stability, reliable limiting structure, and high installation efficiency.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a handle comprising an integrally connected first rod segment, a second rod segment, and a third rod segment. The first rod segment and the third rod segment are symmetrically disposed at both ends of the second rod segment. Each of the first and second rod segments has a rotatable connecting portion at its end away from the second rod segment. Each of the two rotatable connecting portions includes a limiting block and a fixing groove. The limiting block passes through the first and second rod segments, and the middle of both sides of the limiting block is recessed inward to form a fixing groove. The limiting block includes an arc-shaped segment, and both ends of the arc-shaped segment extend outward to form an extension segment.

[0006] Preferably, the extension section is provided with a movable groove, which extends to the end of the arc-shaped section.

[0007] Preferably, the limiting block protrudes from the first rod segment and the second rod segment at both ends.

[0008] Preferably, both the first and third rod segments have weight-reducing grooves on the side near the extension segment, and the weight-reducing grooves pass through the extension segment near the second rod segment.

[0009] Preferably, the first and third rod segments are provided with a limiting groove at the end away from the second rod segment, and the limiting groove is located on the side close to the extension segment.

[0010] A safety box with a carrying handle.

[0011] Preferably, the safety box further includes a lower box body, an upper box body, a lock, and a latch. The upper box body is hinged to the lower box body, the handle is rotatably connected to the lower box body, there are two locks connected to both ends of the handle, and the latch is located between the lower box body and the upper box body.

[0012] Preferably, the lower housing is provided with two mounting parts for connecting the handle. Each mounting part includes two parallel mounting protrusions, and a connecting protrusion is provided on the side of the two mounting protrusions that are close to each other. The connecting protrusion is rotatably connected in the fixing groove by a limiting block.

[0013] Preferably, a reinforcing plate is provided between the two mounting protrusions.

[0014] Preferably, the lower housing is provided with a limiting strip, which is located above the mounting protrusion and is used to match the limiting groove.

[0015] Preferably, the upper housing is provided with shoulder strap connection structures on both sides.

[0016] Compared with the prior art, the beneficial effects of this utility model's technical solution are:

[0017] This utility model provides a lifting handle that achieves a stable rotational connection through a limiting block and a fixing groove. The limiting block penetrates the handle body and rotates with the connecting protrusion of the safety box mounting part, enabling smooth rotation when lifting and providing reliable axial support in a static state, avoiding the problems of loosening or falling off traditional handles. By setting an arc-shaped section and an extension section, the connection part can produce slight elastic deformation under force, buffering stress concentration and enhancing connection elasticity and impact resistance. By setting a movable groove, the limiting block can deform during installation, achieving self-adaptive assembly and improving the overall connection reliability and assembly convenience of the lifting handle.

[0018] The present invention provides a handle that achieves rotation angle control through the cooperation of a limiting groove and a limiting strip. When the handle is in the lowered state, the limiting groove and the limiting strip are engaged with each other to prevent the handle from swinging freely and effectively protect the appearance and structure of the box.

[0019] The present invention provides a carrying handle that significantly reduces the overall weight while maintaining strength by setting weight-reducing grooves in the first and third rod sections, thereby improving carrying comfort. The weight-reducing grooves penetrate one of the extension sections of the limiting block, dividing one of the extension sections into left and right parts, resulting in better deformation performance. Furthermore, the combination of installing protrusions, connecting protrusions, and reinforcing plates enhances the overall load-bearing capacity.

[0020] The safety box provided by this utility model has a firm and reliable connection through the handle, and precise positioning to avoid shaking and wear. It not only significantly improves service life and safety, but also makes installation simple, has a lightweight structure, and reduces manufacturing and maintenance costs.

[0027] The present invention will be further described below with reference to specific embodiments. The accompanying drawings are for illustrative purposes only, representing schematic diagrams rather than actual physical objects, and should not be construed as limiting the present invention. To better illustrate the embodiments of the present invention, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product dimensions. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0028] Example 1

[0029] like Figure 1-3As shown, this utility model provides a handle, including a first rod segment 1, a second rod segment 2, and a third rod segment 3 integrally connected. The first rod segment 1 and the third rod segment 3 are symmetrically arranged at both ends of the second rod segment 2. Each end of the first rod segment 1 and the third rod segment 3 away from the second rod segment 2 is provided with a rotating connecting part 4. Each of the two rotating connecting parts 4 includes a limiting block 401 and a fixing groove 402. The limiting block 401 passes through the first rod segment 1 and the third rod segment 3. The middle of both sides of the limiting block 401 is recessed inward to form a fixing groove 402. The fixing groove 402 is used to rotatably connect to the connector of the safety box. The limiting block 401 includes an arc-shaped segment 4011. Both ends of the arc-shaped segment 4011 extend outward to form an extension segment 4012.

[0030] The handle provided by this utility model is integrally formed and symmetrically arranged with the first rod segment 1, the second rod segment 2, and the third rod segment 3, so that the handle is evenly stressed when lifted, avoiding the phenomenon of uneven load. The cooperation between the limiting block 401 and the fixing groove 402 achieves a stable rotational connection, which improves the connection firmness. By setting the arc-shaped segment 4011 and the extension segment 4012, the elasticity and impact resistance of the connection are enhanced, thereby improving the overall durability and service life of the handle. During installation, after the safety box connector is inserted from the extension segment 4012 into the arc-shaped segment 4011, the extension segment 4012 adaptively returns to its original shape, allowing the connector to rotate within the arc-shaped segment 4011.

[0031] Furthermore, in another embodiment, a movable groove 403 is provided around the extension section 4012, the movable groove 403 extending to the end of the arc-shaped section 4011. During installation, the extension section 4012 deforms within the movable groove 403 to achieve elastic assembly, simplifying the installation process. At the same time, the deformation absorbs some of the installation stress, preventing structural cracking and improving installation accuracy and overall connection stability.

[0032] Furthermore, in another embodiment, the limiting block 401 protrudes from the first rod segment 1 and the third rod segment 3 at both ends.

[0033] The protruding design at both ends of the limit block 401 effectively increases the contact area with the safety box connector, enhances the structural support, makes the handle more stable when lifting heavy objects, and prevents the limit block 401 from loosening or wearing out during long-term use.

[0034] Furthermore, in another embodiment, both the first rod segment 1 and the third rod segment 3 are provided with a weight reduction groove 101 on the side near the extension segment 4012. The weight reduction groove 101 passes through the extension segment 4012 near the second rod segment 2, and the weight reduction groove 101 extends to the movable groove 403 away from the second rod segment 2. That is, the weight reduction groove 101 is connected to the movable groove 403 away from the second rod segment 2.

[0035] By setting the weight reduction groove 101, the overall weight is effectively reduced while maintaining the structural strength of the handle, thus reducing the carrying burden. In addition, the weight reduction groove 101 is connected to the movable groove 403, which divides one of the extensions 4012 of the limiting block 401 into left and right parts, further enhancing the deformation capability of the limiting block 401 during installation, and making the handle more stable under force, thereby extending its service life.

[0036] Furthermore, in another embodiment, the first rod segment 1 and the third rod segment 3 are provided with a limiting groove 102 at the end away from the second rod segment 2. The limiting groove 102 is located on the side close to the extension segment 4012 and is used to limit the position of the handle rotation.

[0037] The limiting groove 102 effectively limits the rotation range of the handle, preventing the handle from swinging freely when placed and avoiding collisions with the box. When lifting, the limiting groove can also assist in positioning, improving stability and carrying comfort.

[0038] like Figure 4-5 As shown, this utility model provides a safety box with a handle, and also includes a lower box body 5, an upper box body 6, a lock 7 and a latch 8. The upper box body 6 is hinged to the lower box body 5, the handle is rotatably connected to the lower box body 5, there are two locks 7, and the locks 7 are connected to both ends of the handle. The latch 8 is located between the lower box body 5 and the upper box body 6.

[0039] The safety box provided by this utility model features a secure and reliable connection between the handle and the safety box, with precise positioning to prevent wobbling and wear. This significantly improves service life and safety, while also simplifying installation, reducing manufacturing and maintenance costs due to its simple installation, lightweight structure, and lower overall cost. Furthermore, the handle's locking mechanism ensures the safety box remains closed while being pulled, enhancing overall protection and security. The rotating connection structure of the handle also allows users to easily switch between opening and carrying modes.

[0040] Furthermore, in another embodiment, the lower housing 5 is provided with two mounting portions for connecting the handle. Each mounting portion includes two parallel mounting protrusions 501, and a connecting protrusion 502 is provided on the side of each mounting protrusion 501 that is close to each other. The connecting protrusion 502 is rotatably connected to the fixing groove 402 via a limiting block 401. The structure of the parallel mounting protrusions 501 and the connecting protrusion 502 makes the force on the handle connection portion more even, reducing torsional stress; the cooperation between the limiting block 401 and the fixing groove 402 achieves a reliable rotational connection, ensuring that the handle is smooth and flexible when lifted and is not easily detached.

[0041] Furthermore, in another embodiment, a reinforcing plate 503 is provided between the two mounting protrusions 501. The reinforcing plate 503 improves the overall rigidity of the mounting part, making the lower box 5 less prone to deformation or cracking when subjected to lifting force, thereby enhancing the stability and durability of the overall structure of the safety box.

[0042] Furthermore, in another embodiment, the lower housing 5 is provided with a limiting strip 504, which is located above the mounting protrusion 501 and is used to match the limiting groove 102. The cooperation between the limiting strip 504 and the limiting groove 102 can achieve precise positioning when the handle is rotated to a preset position, preventing excessive rotation from causing damage to the components. At the same time, it can also stabilize the placement angle of the handle, improving the overall feel and safety of use.

[0043] Furthermore, in another embodiment, the upper housing 6 is provided with shoulder strap connecting structures 9 on both sides, which are used to connect shoulder straps, further increasing the applicable scenarios of the safety box.

[0044] Working principle:

[0045] This utility model provides a handle and a safety box with the handle. When the user lifts the safety box, the handle, composed of a first rod segment 1, a second rod segment 2, and a third rod segment 3, forms a stable load-bearing structure. The second rod segment 2 serves as the central support segment. The first rod segment 1 and the third rod segment 3 are connected to the mounting portion on the lower box body 5 via rotating connecting portions 4 at both ends, allowing the handle to rotate relative to the box body. When the handle is in the lifting state, the arc-shaped segment 4011 of the limiting block 401 and the extension segment 4012 cooperate to fix the groove 402, allowing the handle to rotate smoothly while maintaining stable support and preventing it from loosening during lifting. The movable groove 403 allows the extension segment 4012 to undergo slight deformation during installation or under stress, thereby improving the buffering performance and durability of the connection. When the handle is placed downwards, the limiting groove 102 cooperates with the limiting strip 504 on the lower box body 5 to limit the rotation angle of the handle, ensuring it is firmly attached to the surface of the box body when not in use, preventing shaking or space occupation. The through-hole design of the weight-reducing groove 101 effectively reduces the overall weight while ensuring the structural strength of the handle, making it easy to carry and reducing the burden on the user.

[0046] In the overall assembly structure, the lower housing 5 is rotatably connected to the handle through the mounting part. The mounting part includes two parallel mounting protrusions 501, and the reinforcing plate 503 between them is used to enhance the overall rigidity of the mounting area and prevent deformation or breakage caused by repeated lifting. The connecting protrusion 502 cooperates with the fixing groove 402 of the limiting block 401, so that the handle can rotate smoothly and maintain a firm installation state, realizing the comprehensive functions of stable carrying, flexible rotation and lightweight durability of the safety box. The structure is reasonable, the operation is simple, and it has good practical effect.
