Description

Technical Field

[0001] This utility model relates to the field of handle technology, specifically to a concealed telescopic handle buckle. Background Technology

[0002] Handles are core operating components in industrial settings such as industrial equipment, heavy-duty enclosures, and battery boxes. They are widely used in lifting operations such as equipment handling and component opening and closing. The rationality of their structure directly affects the convenience, safety, and efficiency of industrial operations.

[0003] In existing technologies, handles used in the industrial field generally adopt a fixed length design, that is, the grip section of the handle and the mounting base are an integrated fixed structure, or are rigidly connected by bolts, welding or other methods. The overall length of the handle cannot be adjusted according to actual operating needs after installation. However, fixed-length handles often have certain shortcomings when dealing with complex industrial lifting needs. For example, in industrial production, operators often need to wear heavy cut-resistant gloves, insulating gloves, or non-slip gloves to ensure safety (such as in machining, power maintenance, heavy assembly, and other scenarios). Since the grip space and length of fixed handles are fixed, heavy gloves will increase the grip size of the hand, making it difficult for operators to smoothly put their hands into the handle grip area, or to apply stable pulling force after gripping. This not only reduces operating efficiency, but also easily leads to safety hazards such as equipment falling and parts being damaged due to hand slippage. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a hidden telescopic handle buckle.

[0005] The technical solution adopted by this utility model to solve its technical problem is: A concealed telescopic handle buckle includes a handle, characterized in that: the handle has a concealed cavity, and the outside of the handle has two retraction ports communicating with the concealed cavity; the concealed cavity has a telescopic belt and an elastic retraction mechanism for retracting the telescopic belt into the concealed cavity by elastic force when the handle is not pulled by external force; the middle part of the telescopic belt is wound around the elastic retraction mechanism; the two ends of the telescopic belt extend out of the handle from the two retraction ports respectively; and both ends of the telescopic belt are connected to connecting components located outside the handle.

[0006] In this utility model, the elastic recovery mechanism includes a recovery base and at least one elastic recovery module. The recovery base is provided with a recovery cavity and at least one recovery guide structure. Each recovery guide structure is equipped with an elastic recovery module. The telescopic belt is wound around the elastic recovery module.

[0007] In this utility model, the recycling guide structure includes a first guide groove and a second guide groove provided on the wall of the recycling chamber, and the recycling chamber is provided with inlet and outlet at both ends; The elastic recovery module includes a recovery spring, a first rod, and a second rod. The first rod is guided and engaged with a first guide groove, and the second rod is guided and engaged with a second guide groove. The first and second rods are connected in conjunction with the recovery spring; The telescopic belt is wound around the first rod and / or the second rod, with its two ends extending from the two inlets and outlets of the recovery chamber and passing through the two recovery ports respectively; When the recovery base is pulled, the two ends of the telescopic belt remain stationary due to the constraint of the connecting components and the length extending out of the recovery chamber increases. At the same time, it drives the first rod to move along the first guide groove and the second rod to move along the second guide groove, so that the recovery spring stores energy. When the retrieval base is released, the retrieval spring releases energy and unfolds to push the first and second rods back to their original positions, and drives both ends of the telescopic belt to retract into the retrieval cavity, shortening the extended length to achieve the retrieval action.

[0008] In this invention, there are two elastic recovery modules, which are arranged vertically adjacent to each other. In the two vertically adjacent elastic recovery modules, the first rod of one elastic recovery module corresponds to the second rod of the other elastic recovery module, and the second rod of one elastic recovery module corresponds to the first rod of the other elastic recovery module. One end of the telescopic belt extends from one of the inlets and outlets of the recovery chamber, and the other end passes sequentially around the second rod of one elastic recovery module, the first rod of one elastic recovery module, the first rod of the other elastic recovery module, and the second rod of the other elastic recovery module before extending from the other inlet and outlet of the recovery chamber.

[0009] In this utility model, a support rod is fixedly installed on the first rod, and an avoidance hole is provided on the second rod for the support rod to pass through. The retraction spring is fitted on the support rod, and the two ends of the retraction spring abut against the first rod and the second rod respectively.

[0010] In this invention, at least one inlet and outlet of the recovery chamber is provided with a guide rod, the guide rod is fixed on the recovery base, and the telescopic belt extends out from the inlet and outlet after being wrapped around the guide rod.

[0011] In this utility model, the connecting component includes a connecting seat connected to the telescopic belt and a locking mechanism installed on the connecting seat. The locking mechanism is controlled by the connecting seat connected to it. The telescopic belt is configured to unlock itself when the telescopic belt extends to its limit position, thereby driving the connecting seat to activate the locking mechanism.

[0012] In this utility model, the locking mechanism includes a locking seat, a locking spring, and a movable locking buckle. The movable locking buckle is slidably guided and connected to the locking seat. A linkage shaft is provided on the connecting seat. A limiting seat is provided at the end of the linkage shaft away from the connecting seat, which abuts against the movable locking buckle. The connecting seat, the linkage shaft, and the limiting seat form an unlocking linkage mechanism that links the movable locking buckle to move in the unlocking direction when the telescopic belt extends to its limit position. The locking spring is located between the locking seat and the movable locking buckle. The locking spring is configured to push the movable locking buckle to move and reset in the upward locking direction by elastic force.

[0013] In this utility model, the locking spring is fitted outside the linkage shaft, and the two ends of the locking spring abut against the locking seat and the movable locking buckle, respectively.

[0014] In this utility model, the movable latch includes a latch body and a latch hook integrally formed on the latch body, and the latch hook is provided with an unlocking direction movement guide.

[0015] The beneficial effects of this utility model are as follows: This utility model is equipped with a telescopic belt and an elastic recovery mechanism on the handle. The telescopic belt is connected to a connecting component. When the handle is pulled, since the connecting component is installed on the equipment part, the weight of the equipment part overcomes the elastic force of the elastic recovery mechanism, and the handle moves away from the connecting component. This causes the telescopic belt to be pulled out synchronously under the action of the elastic recovery mechanism, thereby increasing the distance between the handle and the equipment part, making it easier for workers to grip the handle and enabling extended use of the handle to meet the needs of opening or lifting. When the worker releases the handle and the external force is eliminated, the elastic recovery mechanism uses its elasticity to retract the telescopic belt into the hidden cavity, and the handle moves closer to the connecting component to reset. The handle returns to its initial state. The overall structure is compact, the operation is smooth, and the ease of use of the handle buckle is effectively improved.

[0016] In addition, the connecting assembly includes a connecting seat connected to the telescopic belt and a locking mechanism mounted on the connecting seat. The locking mechanism is used to cooperate with the device locking groove of the device body to lock the device component onto the device body. The locking mechanism is controlled by the connecting seat connected to it. The telescopic belt is configured to drive the connecting seat to activate the locking mechanism to unlock when the telescopic belt extends to its limit position. The locking mechanism can ensure the installation stability of the device component on the device body, and the locking mechanism is unlocked by the telescopic belt, which effectively improves the convenience of use.

[0017] In summary, this utility model has a reasonable structural design, the handle is easy and labor-saving to operate, and the locking mechanism is automatically unlocked and reset by pulling out and retracting the telescopic belt. This not only ensures that the equipment parts are locked when not in use, but also improves the operating efficiency when opening. It has good practicality and promotional value.

[0023] Reference Figure 1-7 A concealed telescopic handle buckle is used for installation on equipment component 100. The concealed telescopic handle buckle includes a handle 1. The handle 1 has a concealed cavity 11 inside, and two retraction ports 12 communicating with the concealed cavity 11 are provided on the outside of the handle 1. The concealed cavity 11 is provided with a telescopic belt 2 and an elastic retraction mechanism 3 for retracting the telescopic belt 2 into the concealed cavity 11 by elastic force when the handle 1 is not pulled by external force. The middle part of the telescopic belt 2 is wound around the elastic retraction mechanism 3. The two ends of the telescopic belt 2 extend out of the handle 1 from the two retraction ports 12 respectively. Both ends of the telescopic belt 2 are connected to a connecting component 4 located outside the handle 1. The connecting component 4 is used to cooperate with the equipment component 100.

[0024] When handle 1 is pulled, since connecting component 4 is installed on equipment component 100, the weight of equipment component 100 overcomes the elastic force of elastic recovery mechanism 3, and handle 1 moves away from connecting component 4. This causes telescopic belt 2 to be pulled out synchronously under the action of elastic recovery mechanism 3, thereby increasing the distance between handle 1 and equipment component 100, making it easier for workers to hold handle 1 and extend its use to meet opening or lifting needs. When the worker releases handle 1 to eliminate the external force, elastic recovery mechanism 3 uses its elastic force to retract telescopic belt 2 into hidden cavity 11, and handle 1 moves closer to connecting component 4 to reset. Handle 1 returns to its initial state. The overall structure is compact, the action is smooth, and the ease of use of the handle buckle is effectively improved.

[0025] In this embodiment, the elastic recovery mechanism 3 includes a recovery base 31 and at least one elastic recovery module. The recovery base 31 is provided with a recovery cavity 311 and at least one recovery guide structure. Each recovery guide structure corresponds to one elastic recovery module. The telescopic belt 2 is wound around the elastic recovery module. The recovery guide structure includes a first guide groove and a second guide groove provided on the cavity wall of the recovery cavity 311. The two ends of the recovery cavity 311 are provided with inlet and outlet 312. The elastic recovery module includes a recovery spring 32, a first rod 33 and a second rod 34. The first rod 33 is guided and engaged with the first guide groove and can slide along the first guide groove. The second rod 34 is guided and engaged with the second guide groove and can slide along the second guide groove. The first rod 33 and the second rod 34 are connected to the recovery spring 32. The telescopic belt 2 is wound around the first rod 33 and / or the second rod 34, with its two ends extending from the two inlets and outlets 312 of the recovery cavity 311 and passing through the two recovery ports 12 respectively. When the recovery base 31 is pulled, the two ends of the telescopic belt 2 are constrained by the connecting component 4 and remain stationary, while the length extending out of the recovery cavity 311 increases. At the same time, it drives the first rod 33 to move along the first guide groove and the second rod 34 to move along the second guide groove, so that the recovery spring 32 stores energy. When the recovery base 31 is released, the recovery spring 32 releases energy and unfolds to push the first rod 33 and the second rod 34 to reset, and drives the two ends of the telescopic belt 2 to retract into the recovery cavity 311, so that the extension length shortens to realize the recovery action.

[0026] In this embodiment, there are two elastic recovery modules, arranged vertically adjacent to each other. In the two adjacent elastic recovery modules, the first rod 33 of one elastic recovery module corresponds to the second rod 34 of the other elastic recovery module, and vice versa. One end of the telescopic belt 2 extends from one of the inlet / outlet 312 of the recovery chamber 311, and the other end sequentially passes around the second rod 34, the first rod 33, the first rod 33, and the second rod 34 of one elastic recovery module before extending from the other inlet / outlet 312 of the recovery chamber 311. The portion of the telescopic belt 2 within the recovery chamber 311 forms an S-shape. By using two elastic recovery modules, the handle 1 is not made too large, which would affect the worker's grip. At the same time, increasing the length of the telescopic belt 2 allows the telescopic belt 2 to extend further during use, making it easier for the worker to grip the handle 1. Of course, it is not limited to two elastic recovery modules. In other embodiments, the number of elastic recovery modules is two or more, and each elastic recovery module is arranged sequentially from top to bottom. After the telescopic belt 2 is wound around the first rod 33 and the second rod 34 of each elastic recovery module, the part located in the recovery cavity 311 forms a continuous S-shape, which can be referred to the winding method of the telescopic belt 2 when there are two elastic recovery modules.

[0027] In this embodiment, the first guide groove includes two first guide elongated holes 313 respectively disposed on the two inner walls of the recovery chamber 311. Both ends of the first rod 33 extend into the two first guide elongated holes 313 and can slide along them, thereby achieving the guided installation of the first rod 33. The second guide groove includes two second guide elongated holes 314 respectively disposed on the two inner walls of the recovery chamber 311. Both ends of the second rod 34 extend into the two second guide elongated holes 314 and can slide along them, thereby achieving the guided installation of the second rod 34. Furthermore, the first guide elongated holes 313 and the second guide elongated holes 314 extend in the same direction, thereby ensuring that the telescopic belt 2 can smoothly slide on the outer circumferential surface of the first rod 33 and / or the second rod 34 when it extends or retracts. Even further, the length of the first guide elongated hole 313 is greater than the length of the second guide elongated hole 314, so that the first rod 33 has a larger range of travel during movement.

[0028] In this embodiment, a support rod 35 is fixedly installed on the first rod 33 by a threaded connection, and a clearance hole 341 is provided on the second rod 34 for the support rod 35 to pass through. The retraction spring 32 is fitted on the support rod 35, and the two ends of the retraction spring 32 abut against the first rod 33 and the second rod 34 respectively, thereby providing elastic restoring power when the telescopic belt 2 is retracted, and at the same time, the first rod 33 and the second rod 34 of the same elastic recovery module can share a retraction spring 32. Specifically, the retraction spring 32 is a compression spring. When the handle 1 is pulled, the retraction spring 32 is compressed to store energy; when the handle 1 is released, the retraction spring 32 extends to release energy.

[0029] In this embodiment, at least one inlet / outlet 312 of the recovery chamber 311 is provided with a guide rod 36. The guide rod 36 is fixed on the recovery base 31. The telescopic belt 2 is wrapped around the guide rod 36 and extends out from the inlet / outlet 312, thereby reducing the probability of friction between the telescopic belt 2 and the recovery base 31 during telescopic movement.

[0030] In this embodiment, the surfaces of the first rod 33, the second rod 34, and the guide rod 36 are all smooth surfaces, and the first rod 33, the second rod 34, and the guide rod 36 are all cylindrical.

[0031] In this embodiment, the handle 1 includes a first half-shell 101 and a second half-shell 102, which are connected and fixed by bolts. The inner cavity of the first half-shell 101 and the inner cavity of the second half-shell 102 form the hidden cavity 11. After the first half-shell 101 and the second half-shell 102 are connected and fixed, the recycling base 31 is clamped and fixed in the hidden cavity 11. The first half-shell 101 and the second half-shell 102 are each provided with two hidden slots, which correspond one-to-one to form two recycling ports 12. Alternatively, the first half-shell 101 and the second half-shell 102 are respectively fixed on both sides of the recycling base 31 by bolts, thus realizing the installation of the recycling base 31 at the same time.

[0032] In this embodiment, the connecting component 4 includes a connecting seat 41 connected to the telescopic belt 2 and a locking mechanism mounted on the connecting seat 41. The locking mechanism is used to cooperate with the device locking groove 201 of the device body to lock the device component 100 onto the device body. The locking mechanism is controlled by the connecting seat 41 connected to it. The telescopic belt 2 is configured to drive the connecting seat 41 to activate the locking mechanism to unlock when the telescopic belt 2 extends to its limit position. The locking mechanism can ensure the installation stability of the device component 100 on the device body. At the same time, the locking mechanism is unlocked by the telescopic belt 2, which effectively improves the convenience of use.

[0033] In this embodiment, the locking mechanism includes a locking seat 42, a movable locking buckle 43, and a locking spring 44. The locking seat 42 is connected to the equipment component 100. The movable locking buckle 43 is slidably guided to the locking seat 42. A linkage shaft 411 is provided on the connecting seat 41. A limiting seat 45 abuts against the movable locking buckle 43 at the end of the linkage shaft 411 away from the connecting seat 41. The connecting seat 41, the linkage shaft 411, and the limiting seat 45 form an unlocking linkage mechanism that moves the movable locking buckle 43 in the unlocking direction when the telescopic belt 2 extends to its limit position. The locking spring 44 is located between the locking seat 42 and the movable locking buckle 43. The locking spring 44 is configured to push the movable locking buckle 43 to move and reset in the upward locking direction by elastic force.

[0034] In this embodiment, the locking seat 42 is provided with a first linkage guide hole, and the movable locking buckle 43 is provided with a second linkage guide hole. The end of the linkage shaft 411 away from the connecting seat 41 passes through the first linkage guide hole and the second linkage guide hole in sequence and is then fitted with the limiting seat 45 to improve the quality of the linkage shaft 411 in linkage with the movable locking buckle 43. Furthermore, the connecting seat 41 and the linkage shaft 411 are integrally formed and connected. The linkage shaft 411 is provided with a shaft retaining groove, and the limiting seat 45 is engaged in the shaft retaining groove. Preferably, the limiting seat 45 is a retaining spring with its inner ring engaged in the shaft retaining groove.

[0035] In this embodiment, the locking spring 44 is fitted outside the linkage shaft 411, and the two ends of the locking spring 44 abut against the locking seat 42 and the movable locking buckle 43 respectively, thereby positioning and installing the locking spring 44 to ensure that the locking spring 44 can continuously provide the movable locking buckle 43 with a return force in the locking direction.

[0036] In this embodiment, the telescopic belt 2 is a woven belt, and both ends of the telescopic belt 2 are provided with belt loops 21. The connecting seat 41 is provided with two fixing parts 412 that are respectively inserted into the belt loops 21 from both ends, so as to realize the combined connection between the telescopic belt 2 and the connecting seat 41.

[0037] In this embodiment, the latch seat 42 is provided with a latch sliding cavity 421 and a latch sliding groove. The movable latch 43 is at least partially located within the latch sliding cavity 421. The movable latch 43 is provided with a latch guide portion that slides in the latch sliding groove. The movable latch 43 can slide along the guide of the latch sliding groove, thereby improving the quality of the movable latch 43 when moving in the locking and unlocking directions. At the same time, when the latch guide portion is guided and engaged with the latch sliding groove, the movable latch 43 cannot be rotated relative to the latch seat 42. Specifically, the latch sliding groove is composed of two latch sliding elongated holes 422 respectively provided on opposite sides of the latch sliding cavity 421. The latch guide portion includes two latch flat guide blocks 431, which slide in the two latch sliding elongated holes 422 respectively to achieve guidance.

[0038] In this embodiment, the latch seat 42 includes an integrally formed latch body 423 and two latch side plates 424. The two latch side plates 424 are respectively connected to the same side of the latch body 423 and are spaced apart. The latch body 423 and the two latch side plates 424 together form the latch sliding cavity 421. The first linkage guide hole is provided on the latch body 423, and the two latch sliding elongated holes 422 are respectively provided on the two latch side plates 424 and communicate with the latch sliding cavity 421. Furthermore, the latch flat guide block 431 is provided with a chamfer 432 to facilitate the engagement and entry into the latch sliding elongated hole 422. The chamfer 432 is provided on the end of the latch flat guide block 431 near the connecting seat 41, so that when the movable latch 43 is assembled on the latch seat 42, the chamfer 432 can guide the latch flat guide block 431 to slide smoothly into the latch sliding elongated hole 422, thereby improving assembly efficiency.

[0039] In this embodiment, the movable latch 43 includes a latch body 433 and a latch hook portion 434 integrally formed on the latch body 433. The latch flat guide block 431 is integrally formed on the latch body 433 and / or the latch hook portion 434. The latch hook portion 434 is provided with an unlocking direction movement guide portion, which is an inclined guide slope 435. When the device lock groove 201 acts on the guide slope 435 of the movable latch 43, the guide slope 435 can smoothly contact the device lock groove 201 and guide the movable latch 43 to slide along the unlocking direction. At this time, the movable latch 43 pushes the latch spring 44, causing the latch spring 44 to store force. After the guide slope 435 separates from the device lock groove 201 and the external force is removed, the latch spring 44 releases the stored energy and drives the movable latch 43 to reset along the locking direction until the device component 100 is in place. The movable latch 43 is then locked onto the device lock groove 201, realizing automatic springback locking.

[0040] For example, in this embodiment, the device component 100 connected to the concealed telescopic handle buckle is a lithium battery box. The lithium battery box is used to fit inside the battery compartment of the electrical device 200. The device locking groove 201 is set inside the battery compartment of the electrical device 200. When the lithium battery box is installed into the battery compartment of the electrical device 200, the movable locking buckle 43 of the concealed telescopic handle buckle is guided to slide along the unlocking direction by the guide slope 435 cooperating with the device locking groove 201. When the lithium battery box is inserted into the battery compartment, the movable locking buckle 43 is engaged by the locking spring 44. Under the elastic reset action, it automatically moves along the locking direction, so that the latch hook 434 is engaged in the equipment lock groove 201, thereby locking the lithium battery box; when it is necessary to replace or remove the lithium battery box, the handle 1 is pulled by external force. The handle 1 drives the movable latch 43 to overcome the elastic force of the latch spring 44 and slide along the unlocking direction through the telescopic belt 2 and the unlocking linkage mechanism, so that the latch hook 434 is disengaged from the equipment lock groove 201, thereby releasing the lock on the lithium battery box. At this time, the lithium battery box can be directly lifted out of the battery compartment by the handle 1, thereby realizing the disassembly and replacement of the lithium battery box.

[0041] The above description is only a preferred embodiment of the present utility model. Any technical solution that achieves the purpose of the present utility model by essentially the same means shall fall within the protection scope of the present utility model.
