Description

Technical Field

[0001] This utility model relates to the field of gripping device technology, and in particular to a gripping device that protects the tiger's mouth. Background Technology

[0002] In daily life and work, people frequently use devices that require gripping and applying force, such as knives, tool handles, and fitness equipment. However, traditional grip devices have design shortcomings; their handles are usually simple cylindrical or other shapes without a structure specifically designed to fit the web of the hand. When users grip or exert force for extended periods, the web of the hand is easily subjected to significant pressure and friction, leading to fatigue, soreness, and even injury. Furthermore, the unscientific application of force and the resulting lack of smooth force application also affect operational efficiency and the user experience. Utility Model Content

[0003] In view of this, the present invention aims to provide a thumb-and-shoulder protection and gripping device to solve or alleviate the technical problems existing in the prior art, or at least provide a beneficial alternative.

[0004] The technical solution of this utility model embodiment is implemented as follows:

[0005] A thumb-and-shoulder protection grip device includes a blade body, a grip component mounted on the blade body, and a fixing component mounted on the end of the grip component.

[0006] in:

[0007] The grip component is used to protect the user's thumb and forefinger and assist in efficient force application.

[0008] The fixing component is used to fix the gripping component to the blade body;

[0009] The grip assembly includes a grip piece inserted into the tail of the blade, with a protrusion fixed to one end of the grip piece near the blade, and the protrusion having a curved profile that conforms to the web of the hand.

[0010] The fixing component includes a screw threaded through both the grip and the tail of the blade, with a connecting piece fixed to the end of the screw.

[0011] Preferably, the gripping component has several sets of anti-slip protrusions evenly distributed at its upper and lower positions.

[0012] Preferably, a hanging ring is fixed to the end of the connecting piece.

[0013] Preferably, the gripping member is provided with several sets of fixing pins evenly distributed on it.

[0014] Preferably, the curvature of the curved surface profile ranges from 30° to 80°.

[0015] Preferably, the height of the anti-slip protrusion is 3-6mm, and the distance between two adjacent sets of anti-slip protrusions is 1-2mm.

[0016] Preferably, the screw has a length of 100-150 mm and a diameter of 5-10 mm.

[0017] Preferably, the grip is made of a high-strength material.

[0018] The present invention has the following advantages due to the adoption of the above technical solution:

[0019] I. In response to the problem that traditional gripping devices do not have a structure specifically designed to fit the web of the hand, which leads to fatigue, soreness, or even injury of the web of the hand when the user holds it for a long time or exerts force, this utility model uses a curved contour on the protrusion of the gripping component to fit the web of the hand tightly, dispersing the pressure on the web of the hand, thereby effectively protecting the web of the hand and solving the problem of easy fatigue of the web of the hand.

[0020] Second, in response to the problem that traditional gripping devices suffer from uneven force application and reduced operating efficiency due to unscientific force application points, the curved contour of this utility model provides a stable support point for force application. Combined with anti-slip protrusions to increase friction, it can assist users in applying force efficiently, solve the problem of uneven force application, and improve operating efficiency.

[0021] Third, traditional gripping devices may become loose during use, affecting stability and safety. However, the fixing component of this utility model uses screws to stably fix the gripping component to the blade body, ensuring the stability and safety of the device during use.

[0022] Fourth, traditional gripping devices are inconvenient to store and manage. The hanging ring at the end of the connecting piece of this utility model facilitates the hanging and storage of the device and saves storage space.

[0023] Fifth, the handle structure of traditional gripping devices lacks stability and is prone to deformation and damage after long-term use. The fixing pins on the gripping part of this utility model enhance the structural stability of the gripping part itself, prevent it from deforming or being damaged during long-term use, and extend the service life of the device.

[0024] The above overview is for illustrative purposes only and is not intended to be limiting in any way. In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features of the present invention will become readily apparent from the accompanying drawings and the following detailed description.

[0034] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0035] like Figure 1-4 The present invention provides a thumb-and-shoulder protection and assistive grip device, including a blade body 1, a grip component 2 mounted on the blade body 1, and a fixing component 3 mounted on the end of the grip component 2.

[0036] in:

[0037] As a core functional component, the grip component 2 is designed to address the pain points of traditional grip tools, such as hand fatigue and difficulty in applying force. Through in-depth research into ergonomic principles and a rational structural design, it protects the user's hand and assists in efficient force application. When the user grips the tool, the structure that conforms to the hand's grip allows the force applied to the hand to better conform to the laws of mechanical transmission, reducing energy loss and improving the convenience and comfort of operation.

[0038] The fixing component 3 plays a key role in connection and stabilization, and is used to securely fix the gripping component 2 to the blade body 1. This ensures that the gripping component 2 will not be displaced relative to the blade body 1 in long-term, high-frequency gripping and force application scenarios, thus guaranteeing the overall stability and reliability of the device.

[0039] The grip assembly 2 includes a grip piece 4 inserted into the tail of the blade body 1. As a component that directly contacts the hand, the grip piece 4 has a carefully designed shape and structure. A protrusion 5 is fixed to one end near the blade body 1. The existence of the protrusion 5 is adapted based on the physiological characteristics of the human hand opening. The protrusion 5 has a curved contour 6 that conforms to the hand opening. This curved contour 6 is optimized through a large amount of human hand size data collection and simulation experiments. It can closely fit the hand opening, distribute the pressure on the hand opening, and avoid fatigue and damage caused by excessive local pressure.

[0040] The fixing component 3 includes a screw 7 that is threaded through both the gripper 4 and the tail of the blade 1. A connecting piece 8 is fixed to the end of the screw 7. The screw 7 is connected by a threaded connection, which has the advantages of high connection strength and convenient assembly and disassembly. The connecting piece 8 can increase the force-bearing area at the end of the screw 7, making the fastening effect of the screw 7 on the gripper 4 and the tail of the blade 1 more uniform and stable, ensuring long-term reliable fixing effect.

[0041] In this embodiment, specifically, the grip 4 is provided with several sets of anti-slip protrusions 9 evenly distributed at its upper and lower positions.

[0042] From a functional perspective, the anti-slip protrusion 9 can effectively increase the friction between the grip 4 and the hand. Whether used in a dry environment or in a wet, oily or slippery working environment, it can make the user hold the grip more firmly, prevent operational errors caused by hand slippage, and thus improve the safety and efficiency of operation, and ensure that the force application process is stable and controllable.

[0043] The end of the connecting piece 8 is fixed to the hanging ring 10. The hanging ring 10 provides a convenient solution for the storage and carrying of the device. It can be easily hung on tool racks, hooks, etc., which is convenient for storage and organization, saves storage space, and is also convenient for use in outdoor work, fitness training and other scenarios, improving the convenience of use.

[0044] The grip 4 is evenly provided with several sets of fixing nails 11. The fixing nails 11 strengthen the integrity of the grip 4 itself from the structural level. Under the condition that the grip 4 is subjected to external impact or long-term repeated gripping and force, it can effectively prevent the grip 4 from cracking, deforming and other damage, extend the service life of the grip 4, and ensure the long-term stable use of the device.

[0045] In this embodiment, specifically, the curvature range of the curved surface contour 6 is 40°-80°. This curvature range was determined through extensive testing and mechanical simulation analysis of the human hand's web shape. It can adapt to the physiological structure of the web of most people. During use, it allows the web of the hand to fit perfectly with the curved surface contour 6. On the one hand, it maximizes the distribution of pressure on the web of the hand, reducing fatigue. On the other hand, it can create a stable fulcrum for force application, allowing users to exert force more smoothly and efficiently, thus improving the operating experience and work efficiency.

[0046] The height of the anti-slip protrusions 9 is 3-6mm, and the spacing between two adjacent sets of anti-slip protrusions 9 is 1-2mm. These dimensional parameters are determined by comprehensively considering factors such as the tactile feel of the human hand, friction requirements, and grip comfort. A reasonable height and spacing ensures sufficient anti-slip performance, preventing the hand from slipping during gripping, while avoiding excessively high or dense protrusions that could cause a noticeable foreign body sensation or pressure, thus guaranteeing comfort during extended use.

[0047] The screw 7 has a length of 100-150mm and a diameter of 5-10mm. This screw specification can adapt to the connection requirements between the tail of the cutter body 1 and the gripper 4. The length can ensure that the screw 7 can effectively penetrate and provide sufficient thread engagement length to ensure connection strength. The diameter can ensure that the screw 7 itself has sufficient rigidity and shear resistance. When subjected to various stresses generated by gripping force, it is not easy to deform or break, thus ensuring the reliability of the fixing component 3.

[0048] The grip 4 is made of high-strength material. It combines good mechanical properties with ergonomic fit. Its strength is sufficient to withstand external forces during gripping, making it less prone to breakage. At the same time, it has a certain degree of toughness, so that it will not put excessive pressure on the hand due to the hard material. It is also wear-resistant and corrosion-resistant, and can be used for a long time in various environments (such as the humid environment of the kitchen, the outdoor tool use environment, etc.), ensuring the performance and life of the grip 4. It can also be easily processed into complex shapes that fit the hand and have various functional structures (such as anti-slip protrusions, fixing nail installation positions, etc.) through injection molding and other processes, which facilitates product manufacturing.

[0049] When this utility model is in operation:

[0050] In normal use, the grip component 2 is stably mounted on the blade body 1 by the fixing component 3, eliminating the need for frequent disassembly and allowing for immediate use.

[0051] When the user needs to use the knife for cutting or other operations, they can simply grip the handle 4 mounted on the knife body 1. At this time, the hand naturally conforms to the handle 4, and the curved contour 6 on the protrusion 5 fits snugly against the web of the hand. Since the curvature of the curved contour 6 ranges from 30° to 80°, it can well adapt to the shape of most people's web of the hand, effectively distributing the pressure on the web of the hand during force application, preventing fatigue and soreness caused by excessive localized force, thus protecting the web of the hand. Simultaneously, the curved contour 6 provides a stable support point for force application, and together with several sets of anti-slip protrusions 9 evenly distributed at the top and bottom of the handle 4, it increases the friction between the hand and the handle 4, preventing slippage and making the user's force application smoother and more efficient, improving the efficiency and accuracy of cutting and other operations.

[0052] During long-term use of the device, the screw 7 in the fixing component 3 is threaded through both the gripping component 4 and the tail of the blade body 1, which can firmly fix the gripping component 2 to the blade body 1, ensuring that the gripping component 2 will not shift relative to the blade body 1, thus guaranteeing stability and safety during use. The gripping component 4 is made of high-strength nylon material and has several sets of fixing pins 11 evenly distributed on it. This gives the gripping component 4 high structural stability and strength, enabling it to withstand various stresses from long-term gripping, preventing deformation and damage, and extending the service life of the device.

[0053] When the knife is not in use, since the end of the connecting piece 8 is fixed with the hanging ring 10, the knife body 1 with the gripping device installed can be suspended in a suitable position through the hanging ring 10, which is convenient for storage and management, saves storage space, and also makes it easy to quickly retrieve when used next time.

[0054] In summary, this device improves operational comfort: the curved contour 6 that conforms to the web of the hand and the mechanically optimized grip shape allow the user's web of the hand to naturally adapt and distribute force evenly, avoiding fatigue and soreness caused by unreasonable force distribution during prolonged gripping, and adapting to the needs of different hand shapes and force application habits; it improves work efficiency: the integrated grip component 2 has the functions of protecting the web of the hand and assisting force application, eliminating the need for users to adjust their grip posture or overcome hand discomfort to apply force. The fixing component 3 enables quick and stable assembly, and the anti-slip protrusions 9 and fixing nails 11 on the grip 4 ensure grip stability and the durability of its own structure, reducing the time wasted on operation interruptions and repeated adjustments due to grip problems, making operation more efficient and convenient; it enhances equipment applicability: the grip 4 is made of high-strength material, and the screw 7, connecting piece 8, etc. are adapted to the tail structure of different blades 1 for installation. The hanging ring 10 facilitates storage and management, making it suitable for various scenarios requiring gripping and force application, such as knives, tool handles, and fitness equipment.

[0055] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
