Description
Technical Field
[0001] The utility model relates to the field of hanging labor-saving devices, and particularly relates to a backpack anti-falling hanging device. Background Art
[0002] With the development of industry, the weights of some power tools, especially new energy power tools, are getting heavier and heavier. It is very laborious for workers to hold and operate them, and they cannot work continuously. In recent years, some spring balancers have emerged. They are carried on the backs of users for suspension, so as to achieve the purpose of labor saving and can work continuously for a long time. However, the inventor found in the actual use process that the existing backpack-type spring balancers are suspended by a single suspension rope. After suspension, it is impossible to ensure that the power tool will not fall, resulting in the safety of workers not being guaranteed during the work process. Therefore, there is an urgent need to provide a backpack anti-falling hanging device to solve the above problems. Summary of the Invention
[0003] For this reason, it is necessary to provide a backpack anti-falling hanging device with high safety and easy to use.
[0004] To achieve the above object, the inventor provides a backpack anti-falling hanging device, including: a backpack, a support mechanism, and an anti-falling mechanism. One end of the support mechanism is fixedly connected to the backpack. A balancer is arranged in the backpack. The suspension rope in the balancer extends along the support mechanism to the other end of the support mechanism. One end of the anti-falling mechanism is connected to the support mechanism or the backpack.
[0005] As a preferred structure of the utility model, the support mechanism includes a first support rod and a second support rod. One end of the first support rod is fixedly connected to the backpack. The other end of the first support rod is connected to one end of the second support rod. The suspension rope in the balancer extends along the first support rod and the second support rod to the other end of the second support rod. One end of the anti-falling mechanism is arranged on the second support rod.
[0006] As a preferred structure of the utility model, the anti-falling mechanism is an anti-falling rope. One end of the anti-falling rope is connected to the other end of the second support rod.
[0007] As a preferred structure of the utility model, the anti-falling rope is a lock-type anti-falling rope. A fixed beam is arranged at the end of the other end of the second support rod. The lock-type anti-falling rope is connected to the fixed beam through a lock.
[0008] As a preferred structure of the utility model, the support mechanism includes a first support rod, a second support rod, and a support assembly. The other end of the first support rod is movably and detachably connected to one end of the second support rod through the support assembly.
[0009] As a preferred structure of the present utility model, the support assembly includes a pair of clamping plates and fixing pins. The first support rod is vertically arranged on the backpack. The pair of clamping plates are clamped on both sides of the first support rod, and the clamping plates are fixedly connected to the first support rod. The second support plate is horizontally arranged and is fixedly connected to the clamping plates through the fixing pins.
[0010] As a preferred structure of the present utility model, the support assembly further includes a diagonal brace. The diagonal brace is obliquely arranged between the clamping plates and is fixedly connected to the clamping plates. One end of the diagonal brace is connected to the first support rod, and the other end is connected to the second support rod.
[0011] As a preferred structure of the present utility model, a first roller bearing is arranged above the first support rod between the clamping plates, and a second roller bearing is arranged inside one end of the second support rod close to the clamping plate.

[0015] Different from the prior art, the beneficial effects achieved by the above technical solutions are as follows:
[0016] The anti-falling structure of the backpack of this device is set up to effectively facilitate the use by the user and save physical strength. After assembling the support mechanism, namely the first support rod and the second support rod, the user can carry the entire device on the back. Under the action of the balancer, the suspension rope can lift the power tool to perform the operation. During this process, the user does not need to use great strength to lift the power tool anymore. The user only needs to control the operation position and direction of the power tool. Throughout the process, the support mechanism provides the supporting force for lifting the power tool, and the balancer provides the pulling force. Moreover, when the user is using the power tool, if the suspension rope suddenly loosens or breaks, the power tool will suddenly fall, which is very likely to cause injury to the user and damage to the power tool when it hits the ground. The other end of the anti-falling mechanism of this device is connected to the power tool, which can effectively prevent the power tool from falling due to the sudden loosening or breaking of the suspension rope, effectively improving the safety of this device and enabling the user to work continuously in a safe environment.

[0025] To describe in detail the technical content, structural features, achieved objectives and effects of the technical solution, the following will be described in detail with reference to specific embodiments and in conjunction with the accompanying drawings.
[0026] As Figure 1 shown, this embodiment provides a backpack anti-falling suspension device, including: a backpack 1, a support mechanism 2 and an anti-falling mechanism. One end of the support mechanism 2 is fixedly connected to the backpack 1. A balancer 101 is provided in the backpack. The suspension rope in the balancer 101 extends along the support mechanism 2 to the other end of the support mechanism. One end of the anti-falling mechanism is connected to the support mechanism or the backpack.
[0027] In the above embodiment, one end of the anti-falling mechanism can be connected to the support mechanism or the backpack. The support mechanism 2 includes a first support rod 201 and a second support rod 202. One end of the first support rod is fixedly connected to the backpack. The other end of the first support rod is connected to one end of the second support rod. The suspension rope in the balancer extends along the first support rod and the second support rod to the other end of the second support rod. Therefore, one end of the anti-falling mechanism can be connected to the first support rod or the second support rod. In this embodiment, one end of the anti-falling mechanism is provided on the second support rod; that is, as Figure 1 shown, in this embodiment, the anti-falling mechanism uses an anti-falling rope. One end of the anti-falling rope is connected to the other end of the second support rod, and the other end of the anti-falling rope is connected to a handheld tool, thereby avoiding the situation where the suspension rope breaks, causing the handheld tool to fall, damaging the handheld tool, and causing personal injury; of course, in different embodiments, the anti-falling mechanism can also be other structures, such as: anti-falling rods, anti-falling steel wires, anti-falling nets, etc.
[0028] In this embodiment, the anti-falling rope can be a lock-type anti-falling rope. A fixed beam is provided at the other end of the second support rod. The lock-type anti-falling rope is tightly connected to the fixed beam through a lock.
[0029] In the above embodiments, the support mechanism further includes a support assembly 3. In this embodiment, one end of the anti-falling mechanism can also be connected to the support assembly; the other end of the first support rod 201 is movably and detachably connected to one end of the second support rod 202 through the support assembly 3, and the suspension rope in the balancer 101 extends along the first support rod 201 and the second support rod 202 to the other end of the second support rod 202. In the specific implementation process of this embodiment, the backpack-type structure can effectively facilitate the use by the user. After assembling the first support rod and the second support rod during use, the user can carry the entire device on the back through the backpack. The second support rod extends horizontally from above the user's head to the front, and under the action of the balancer, the suspension rope can lift the power tool, which can be a new energy power tool, to perform operations. During this process, the first support rod and the second support rod provide the bearing capacity; and the second support rod in this device is movably and detachably connected to the first support rod through the support assembly, so that it can effectively achieve rotation, folding, and detachment. That is, when not in use, it can be folded or disassembled and then stored, which can greatly reduce the product packaging volume and facilitate transportation and storage.
[0030] As Figure 1 and Figure 2 shown, in the above embodiments, the movable and detachable connection can be: the support assembly 3 includes a pair of clamping plates 301 and a fixing pin 302. The first support rod 201 is vertically arranged on the backpack, and the pair of clamping plates 301 are clamped on both sides of the first support rod 201. The clamping plates are fixedly connected to the first support rod. The second support plate is horizontally arranged and is fixedly connected to the clamping plates 301 through the fixing pin 302. That is, in this embodiment, the movable and detachable connection between the first support rod and the second support rod is realized through the clamping plates and the fixing pin, so as to facilitate the storage and handling of this device; in addition, in this embodiment, the setting of the clamping plates and the fixing pin can not only realize the movable and detachable connection between the first support rod and the second support rod, but also provide a supporting force for the second support rod, thereby increasing the bearing capacity of the second support rod. Of course, in different embodiments, the movable and detachable connection can also be directly realized through a pin shaft or a hinge.
[0031] As Figure 2 shown, in some embodiments, the support assembly 3 further includes a diagonal brace 303. The diagonal brace 303 is inclined between the clamping plates and is fixedly connected to the clamping plates. One end of the diagonal brace 303 is connected to the first support rod, and the other end is connected to the second support rod. The inclined setting of the diagonal brace can further increase the bearing capacity of the second support rod and prevent the second support rod from breaking or bending.
[0032] In certain embodiments, as Figure 2 and Figure 3As shown in the figure, a first roller bearing 401 is provided above the first support rod located between the clamping plates. A second roller bearing 402 is provided inside one end of the second support rod close to the clamping plate. The suspension rope of the balancer 101 passes through the first support rod 201, is successively wound around the first roller bearing 401 and the second roller bearing 402, and passes through the second support rod 202 and extends out of the front end of the second support rod 202. In this embodiment, the settings of the first roller bearing and the second roller bearing can effectively provide a guiding effect on the suspension rope, and make the suspension rope smoother during the working process, avoiding rope jamming and reducing wear.
[0033] In different embodiments, such as Figure 4 and Figure 5 As shown in the figure, a third roller bearing 403 is provided at the front end of the second support rod. After the suspension rope passes through the second support rod 202, it is wound and connected with the third roller bearing 403 and extends out of the second support rod 202. In this embodiment, the setting of the second roller bearing can prevent the front end of the suspension rope from directly contacting the second support rod, thereby avoiding rope jamming and reducing wear.
[0034] In addition, in order to facilitate lifting power tools, such as Figure 4 and Figure 5 As shown in the figure, in some embodiments, a hook 404 is provided at the front end of the suspension rope, and an anti-pinch ball 405 is provided between the hook 404 and the second support rod 202. In this embodiment, the setting of the anti-pinch ball can effectively prevent the hand from being pinched between the hook and the second support rod when the suspension rope is retracted or pulled out, thus avoiding the occurrence of pinching injuries. Since the top end face of the anti-pinch ball is arc-shaped and the contact with the second support rod is point contact, the hand is not easily pinched in the middle.
[0035] Such as Figure 2 and Figure 4 As shown in the figure, in this embodiment, the first support rod 201 is a telescopic rod 5. The telescopic rod 5 structure can adjust the overall height of the machine for workers of different body types, so that the operator can obtain a larger activity space in a narrow space. Specifically: The first support rod 201 includes a mother pipe 501 and a son pipe 502. One end of the son pipe is sleeved inside the mother pipe and is connected by a pin shaft 503. Of course, in different embodiments, the telescopic rod 5 can also be a telescopic rod with driving force, etc.
[0036] Such as Figure 6As shown, a fixing plate 102 is provided inside the backpack. The bottom end of the first support rod is fixedly connected to the fixing plate 102. A wedge block 103 is provided between the fixing plate 102 and the first support rod 201, and the thickness of the wedge block 103 gradually becomes thinner from top to bottom. In this embodiment, the setting of the wedge block 103 and the structure that the wedge block 103 gradually becomes thinner from top to bottom can make the first support rod tilt outward at an appropriate angle from bottom to top. In this way, when the user uses it, it can provide the user's head with the activity space to lean backward, avoiding the collision between the user's head and the first support rod. The setting of this activity space can effectively relieve the user's head fatigue.
[0037] It should be noted that although the above embodiments have been described in this article, the patent protection scope of the present invention is not limited thereby. Therefore, based on the innovative concept of the present invention, the changes and modifications made to the embodiments described in this article, or the equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, directly or indirectly applying the above technical solutions to other related technical fields, are all included in the patent protection scope of the present invention.
