Technical Field

[0001] This utility model belongs to the field of hydraulic equipment technology and relates to a quick-release handle mechanism that is compatible with multiple ring diameters. Background Technology

[0002] In fields such as fire-fighting engineering machinery, hydraulic shears, hydraulic electric demolition equipment, and small and medium-sized hydraulic equipment, hydraulic cylinders are important power devices. When using the equipment, handles are installed on the hydraulic cylinders for users to carry and perform various operations.

[0003] However, in existing equipment, the handle design is usually customized for a specific model or size of hydraulic cylinder. This means that each model of hydraulic cylinder needs to be matched with a handle of the corresponding size. These handles are usually connected to the hydraulic cylinder by bolts, nuts or other fixing devices. When it is necessary to adapt to hydraulic cylinders of different sizes, the entire handle must be disassembled and replaced. This process often requires the use of tools and is relatively time-consuming. In emergency situations, such as fire rescue, complex disassembly and assembly may lead to low rescue efficiency. At the same time, the customized design of the handle means that multiple handles need to be prepared for different hydraulic cylinders, which greatly increases the variety of materials and inventory costs.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A quick-release handle mechanism compatible with multiple ring diameters includes a main handle and a connecting ring. The main handle has a ring hole. The connecting ring includes an inner ring for connecting with a hydraulic cylinder and an outer ring for connecting with the ring hole. The outer ring and the ring hole are respectively provided with a groove and a buckle for forming abutments in the radial direction. The two ends of the outer ring are respectively provided with a wire snap ring and a limiting step for abutting the ring hole in the axial direction.

[0007] Furthermore, the slot is disposed at the axial front end of the outer wall of the outer ring, and an opening is formed at the front end of the outer ring for the buckle to enter axially, and the buckle protrudes from the inner circumference of the ring hole.

[0008] Furthermore, both the slots and the buckles are provided in multiples and distributed along a circular array.

[0009] Furthermore, the front end of the outer ring is provided with a circumferentially recessed groove, and the wire snap ring is engaged in the groove.

[0010] Furthermore, the annular groove and the card slot are intersecting and connected.

[0011] Furthermore, the inner ring is sleeved on the outer circumference of the oil cylinder, the connecting ring is fixedly connected to the oil cylinder by screws, and the inner ring is formed to a set size that is adapted to the oil cylinder by machining process.

[0012] Furthermore, the limiting step is radially protruding from the rear end of the outer ring, and the rear end of the ring hole is provided with a step groove for the limiting step to be inserted.

[0013] In summary, the advantages of this utility model are as follows:

[0014] This utility model adopts a split design of main handle and connecting ring. By adapting the outer ring of the main handle to the outer ring of the connecting ring, and adapting the inner ring of the connecting ring to different specifications of hydraulic cylinders, one main handle can be adapted to be installed on a variety of different specifications of hydraulic cylinders. This reduces the need to purchase and store multiple special handles for different equipment, reduces costs, and improves the flexibility of parts use.

[0015] The use of a slot structure and a steel wire spring stepped structure forms a stable radial and axial limit, ensuring a secure connection between the main handle and the connecting ring, effectively preventing shaking or detachment during operation, and increasing operational safety.

[0016] The quick-release structure of the wire snap ring and buckle greatly reduces the difficulty of operation, reduces the time and labor intensity required to replace the handle, significantly improves the user experience and work efficiency, and the compactness and portability brought by the quick-release structure make the parts easy to carry and operate, making it highly applicable to various scenarios, especially suitable for occasions that require on-site or field operations.

[0027] This embodiment provides a quick-release handle mechanism that is compatible with multiple ring diameters, refer to... Figure 1 and Figure 2 It includes a main handle 2 and a connecting ring 3. The main body of the connecting ring 3 is a ring structure, which is installed on the hydraulic cylinder 1 and forms a fixed connection with the hydraulic cylinder 1. The connecting ring 3 is designed to be compatible with various models and specifications of hydraulic cylinder 1. The main handle 2 and the connecting ring 3 are connected through a detachable structure. When the main handle 2 and the connecting ring 3 are connected, they form a fixed relationship and are used by the user to perform various operations on the hydraulic cylinder 1.

[0028] The connecting ring 3 includes an inner ring and an outer ring. The connecting ring 3 cooperates with the oil cylinder 1 through the inner ring. The ring is sleeved on the oil cylinder 1 and fixed by the screw 5. For different models of oil cylinder 1, the connecting ring 3 can be adapted to different models of oil cylinder 1 by adjusting the size and specifications of the inner ring.

[0029] Preferably, the outer ring of the connecting ring 3 adopts a uniform structural size, and the inner ring of the connecting ring 3 can be machined using a machining process to produce an inner ring size and specification that matches the model and specifications of the hydraulic cylinder 1.

[0030] The main handle 2 has a ring hole in the middle, and the inner circumference of the ring hole is fitted with the outer ring of the connecting ring 3 for installation. (Refer to...) Figure 4 The detachable structure includes a buckle 2-1 protruding from the inner circumferential wall of the annular hole, preferably located at the front end of the annular hole in the axial direction. A groove 3-1 is recessed on the outer wall of the outer ring, preferably located at the front end of the outer ring in the axial direction, and forming an open opening at the front end of the outer ring in the axial direction for the buckle 2-1 to enter. The main handle 2 and the connecting ring 3 are assembled in a coaxial direction, so that the buckle 2-1 enters the groove 3-1 in the front-back direction. When the buckle 2-1 is located in the groove 3-1, it limits the main handle 2 and the connecting ring 3 in the radial direction.

[0031] Preferably, the number of buckles 2-1 can be set to multiple, and they are distributed in a ring array on the inner peripheral wall of the ring hole. The number of slots 3-1 is also set to multiple, and they are distributed in a ring array on the outer wall of the outer ring, thereby improving the fit strength between the main handle 2 and the connecting ring 3.

[0032] The detachable structure also includes a wire snap ring 4, which is a ring structure. The ring is sleeved on the outside of the outer ring. The outer wall of the outer ring is recessed in the circumferential direction with a ring groove 3-3, so that the wire snap ring 4 can be embedded in the ring groove 3-3 and fixed with the outer ring. The ring groove 3-3 is located at the front end of the outer ring in the axial direction. The wire snap ring 4 is engaged in the ring groove 3-3, so that the wire snap ring 4 abuts against the front end of the ring hole, thus limiting the main handle 2 in the axial direction.

[0033] The front end or middle part of the slot 3-1 can also intersect with the annular groove 3-3 to form a connection. When the wire snap ring 4 is installed in the annular groove 3-3, the wire snap ring 4 blocks the open opening of the slot 3-1, so that the buckle 2-1 located in the slot 3-1 is also blocked by the wire snap ring 4 and cannot move axially. Through the slot 3-1 and the wire snap ring 4 respectively limiting the radial rotation and axial movement of the buckle 2-1, the main handle 2 and the connecting ring 3 form a stable fixed connection.

[0034] Furthermore, refer to Figure 3 The outer ring has a radially protruding limiting step 3-2 at the rear end. The inner circumference of the rear end of the ring hole has a stepped groove 2-2 that mates with the limiting step 3-2. When the main handle 2 and the connecting ring 3 are installed, the limiting step 3-2 is embedded in the stepped groove 2-2 and abuts against the rear end of the stepped groove 2-2, forming an axial limit on the rear end of the ring hole. Combined with the axial limit at the front end provided by the wire snap ring 4, the main handle 2 and the connecting ring 3 are tightly fitted to prevent loosening or movement.

[0035] During disassembly, the main handle 2 can be removed from the connecting ring 3 by removing the wire snap ring 4 from the ring groove 3-3, thus achieving quick disassembly.

[0036] In some embodiments, the detachable structure may also be a magnetic component, which is respectively disposed on the connecting ring 3 and the main handle 2, so that a magnetic connection is formed between the connecting ring 3 and the main handle 2, which provides faster connection and disassembly speed while further reducing mechanical wear and extending service life.

[0037] In some embodiments, the detachable structure may also be a slide rail connection structure, which enables the main handle 2 and the connecting ring 3 to be quickly connected and disconnected through relative sliding.

[0038] In some embodiments, the detachable structure is a torsion locking structure. By setting a latch on the main handle 2 or the connecting ring 3, the main handle 2 and the connecting ring 3 are locked together by relative rotation, and the latch is operated to unlock and detach.

[0039] In some embodiments, the detachable structure is a spring-pressing structure, including a spring button and a lock hole respectively provided on the main handle 2 and the connecting ring 3. The main handle 2 and the connecting ring 3 are locked together by operating the spring button so that it is engaged in the lock hole, and the main handle 2 and the connecting ring 3 are removed and detached by pressing the spring button so that it is disengaged from the lock hole.

[0040] Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort should fall within the protection scope of this utility model.
