Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of insulation operation, in particular to a gripping device. BACKGROUND

[0002] High-voltage insulating gloves are key protective equipment for the safety of operating personnel during live-line work in the power industry. Its basic function is to isolate current and prevent electric shock. In actual operation, operating personnel need to wear such gloves to grip and operate various tools or insulating rods. Therefore, in addition to excellent insulation performance, the anti-slip performance of the gloves is also crucial, directly related to the operation efficiency and safety.

[0003] At present, common anti-slip insulating gloves mostly use the method of making uniform distribution of anti-slip protrusions or textures on the surface of the gloves to increase friction. However, this uniform distribution design has obvious limitations: first, it does not take into account the differences in muscle thickness, force exertion method and contact pressure of different areas when the hand grips, resulting in insufficient anti-slip force at the main force exertion point, while the texture in the non-contact area or joint bending area may affect the flexibility and comfort of the hand, and long-time operation may cause muscle fatigue. Second, such texture mainly relies on physical friction, and the anti-slip effect will decrease significantly in the working conditions of sweaty palms, rainy and humid weather, or contact with oil stains, etc., which may cause the tool to slip and pose a safety hazard. Although some technologies have tried to improve, such as thickening the coating at certain finger positions, but overall, they have not broken through the idea of uniform distribution of anti-slip structures, and cannot fundamentally improve the stability of gripping. SUMMARY

[0004] Therefore, the present application provides a gripping device, which is mainly aimed at solving the technical problems of insufficient anti-slip force at the main force exertion point of the existing anti-slip insulating gloves, affecting the flexibility and comfort of the hand, and the anti-slip effect will decrease significantly in the working conditions of sweaty palms, rainy and humid weather, or contact with oil stains, etc., which may cause the tool to slip and pose a safety hazard.

[0005] The present application provides a gripping device, which comprises: a glove body, the glove body comprising a palm part and a finger part; a plurality of suction cup assemblies, the suction cup assemblies being provided on the glove body.

[0006] In a feasible implementation, the palm part comprises: a first sub-area corresponding to the thenar eminence when the glove body is worn on a human hand; a second sub-area corresponding to the hypothenar eminence when the glove body is worn on a human hand.

They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0021] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0022] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0023] In ergonomics and biomechanics, the human hand is an extremely precise organ for grasping and manipulating. Its structure comprises multiple bones, numerous joints, a complex system of muscles and tendons, and the skin covering its surface. The palm mainly includes the carpal bones, metacarpal bones, and well-developed thenar and hypothenar muscles, which provide the primary power and support for grasping. The fingers are connected by multiple phalanges through interphalangeal and metacarpophalangeal joints, enabling them to perform fine movements such as flexion, extension, opposition, adduction, and abduction. The skin covering the bones and muscles, especially in the fingertips and the thenar and hypothenar eminences, has abundant tactile receptors and unique skin textures to enhance friction and sensation. Simultaneously, the palmar skin is relatively firm at the palmar aponeurosis, while redundant folds at the major joint creases accommodate grasping movements. This complex structure works in concert, allowing the human hand to perform both powerful grips and extremely delicate operations, with significant differences in the force, contact state, and functional requirements of different areas during grasping movements. However, existing gripping device designs often treat the hand as a uniform contact surface, with anti-slip structures arranged in uniform or simple zones. This fails to adequately consider and adapt to the anatomical characteristics of the hand's bones, joints, and muscles, as well as the mechanical and functional differences in skin across different areas. This results in room for improvement in gripping performance, operational flexibility, and long-term wearing comfort. This application aims to address the problem of smooth surfaces and insufficient gripping force in existing insulating gloves. By mimicking the suction cup structure of octopus tentacles, and considering that the size and distribution of the suction cups are closely related to the muscle distribution in the human hand, this application overcomes the limitation of the "uniform distribution" of anti-slip textures in traditional insulating gloves. Through analysis of the muscle exertion heat map of the human hand when gripping high-voltage electrical tools, a "muscle group-suction cup" mapping model is established. Based on the muscle thickness, exertion characteristics, and movement trajectory of different hand areas, the size, depth, and arrangement density of the suction cups are differentiated, providing a high-voltage insulating glove with dual anti-slip functions of physical friction and negative pressure adsorption.

[0024] See Figure 1 The diagram shows a structural schematic of a gripping device provided in an embodiment of this application, comprising: The glove body includes the palm and fingers; There are multiple types and quantities of suction cup components, which are installed on the glove body.

[0025] In the above embodiments, the glove body forms the basis of the gripping device. It is made of rubber material that meets high-voltage insulation requirements and is shaped to fit the hand, including a palm portion covering the palm and a finger portion covering the five fingers. The suction cup assembly comprises numerous suction cup units of various types and sizes, arranged on the palm side of the glove body for contacting the tool. Each suction cup unit has a concave cup-shaped or annular protrusion structure, with the edges bulging outwards and the center concave inwards, forming a negative pressure chamber. When the glove contacts an object surface and is squeezed, air is expelled from the suction cup; when the grip is relaxed or maintained, a vacuum negative pressure is formed inside the suction cup, thereby generating suction force.

[0026] This application combines the principle of biomimetic adsorption with personal protective equipment, so that the gloves not only rely on traditional friction and anti-slip, but also generate additional adsorption force through suction cups when in contact with tool surfaces, thus providing stable and reliable grip force even in harsh working conditions such as wet and oily conditions, thereby fundamentally improving work safety.

[0027] Furthermore, the palm portion includes: First section 1, the first section 1 is located at the part of the thenar eminence when the glove body is worn on a person's hand; The second section 2 is located at the part of the hypothenar eminence when the glove body is worn on a person's hand.

[0028] In the above embodiment, the palm is further divided into two key regions. The first region 1 corresponds precisely to the thenar eminence of the palm, that is, the area with abundant muscle at the base of the thumb. The second region 2 corresponds to the hypothenar eminence of the palm, that is, the area with abundant muscle at the base of the little finger.

[0029] Based on the analysis of human hand grip mechanics, this application divides the palm surface into a primary force support area and an auxiliary support area, providing a precise positioning basis for subsequent differentiated functional structure settings, enabling targeted improvements to the technical solution that conform to ergonomic principles.

[0030] Furthermore, the finger portion includes: The third section 3 is located at the part corresponding to the distal phalanx of the thumb when the glove body is worn on the human hand; Section 4 is located at the proximal joints of the thumb, index finger, middle finger, ring finger, and little finger when the glove is worn on the hand.

[0031] In the above embodiment, the finger area is also subdivided. The third section 3 corresponds to the thumb tip area, that is, the area covered by the distal phalanx of the thumb. The fourth section 4 corresponds to the first phalanx area of ​​all five fingers near the palm, that is, the area covered by the proximal phalanx of each finger.

[0032] This application identifies the unique role of the thumb tip in fine manipulation such as pinching and pressing, as well as the important role of the proximal joints of each finger in overall grasping and force application. This helps to customize the design according to the functional needs of different finger joints, thereby balancing overall grip strength and local operation precision.

[0033] Furthermore, the finger area also includes: The fifth section 5 is located at the part corresponding to the middle joint of the index, middle, ring, and little fingers when the glove is worn on a person's hand; Section 6 is located at the distal joints of the index, middle, ring, and little fingers when the glove is worn on the hand.

[0034] In the above embodiment, the division of the fingers is further refined. The fifth section 5 corresponds to the middle phalanx area of ​​the index, middle, ring, and little fingers, that is, the middle phalanx bone coverage area. The sixth section 6 corresponds to the fingertip area of ​​the index, middle, ring, and little fingers, that is, the distal phalanx bone coverage area.

[0035] This application refines the atlas of the functional areas of the entire finger, particularly clarifying the different roles of the middle and distal phalanges of the four fingers. The middle phalanx often participates in flexion and assists in force generation, while the distal phalanx is the most sensitive tactile part and the direct site for fine manipulation, providing a clear basis for implementing differentiated surface treatments in these areas.

[0036] Furthermore, the suction cup assembly includes: The first suction cup group is located in the first partition 1; The second suction cup group is located in the second partition 2.

[0037] In the above embodiment, the suction cup assembly specifically includes two sets of designs for the palm. The first suction cup set is centrally located in the first partition 1, i.e., the thenar eminence area. The second suction cup set is located in the second partition 2, i.e., the hypothenar eminence area.

[0038] By independently setting suction cup groups in the two main support areas of the palm, the size, density, and arrangement of the suction cups can be independently designed according to the different pressures and functions that these two areas bear in actual gripping, thereby achieving optimized distribution of gripping force in the palm area and providing the strongest anti-slip protection for the main load-bearing areas.

[0039] Furthermore, the suction cup assembly also includes: The third suction cup group is located in the third partition 3. The fourth suction cup group is located in the fourth partition 4.

[0040] In the above embodiment, the suction cup assembly further includes designs targeting the thumb and the base of the fingers. A third suction cup group is disposed in the third section 3, i.e., the tip of the thumb. A fourth suction cup group is disposed in the fourth section 4, i.e., the proximal phalanx of all fingers.

[0041] This application extends the suction function to the fingers. The suction cup at the tip of the thumb helps to secure the grip, while the suction cups on the proximal phalanges of all the fingers play a crucial anchoring role when holding cylindrical tools, preventing the tools from rolling or slipping out of the hand and enhancing the stability of multi-finger coordinated grip.

[0042] Furthermore, the suction cup assembly also includes: The fifth suction cup group is located in the fifth section 5; The sixth suction cup group is located in the sixth section 6.

[0043] In the above embodiments, the definition of the suction cup assembly is further supplemented to cover all finger areas. A fifth suction cup assembly is located in the fifth section 5, i.e., the middle phalanx of the four fingers. A sixth suction cup assembly is located in the sixth section 6, i.e., the distal phalanx of the four fingers.

[0044] This application ensures continuous and comprehensive suction across the entire gripping surface, from the palm to the fingertips. The suction cup on the middle fingertip provides auxiliary suction force during a full grip, while the micro-suction cup on the distal fingertip adds an extra micro-suction effect while ensuring precise tactile feedback and operational flexibility, thus enhancing the delicacy and control of the operation.

[0045] Furthermore, the suction cups of the first suction cup group are larger than those of the third suction cup group, the suction cups of the third suction cup group are larger than those of the second suction cup group, the suction cups of the second suction cup group are larger than those of the fourth suction cup group, the suction cups of the fourth suction cup group are larger than those of the fifth suction cup group, and the suction cups of the fifth suction cup group are larger than those of the sixth suction cup group.

[0046] In the above embodiments, the size relationship of the suction cups in the six suction cup groups is clearly defined. The suction cups in the first suction cup group are the largest, followed by the suction cups in the third suction cup group, then the second, fourth, and fifth suction cup groups, while the suction cups in the sixth suction cup group are the smallest.

[0047] This gradient design in size is not arbitrary, but strictly follows the pressure distribution, contact area, and functional requirements of different areas of the hand during gripping. The thenar eminence and thumb tip are the core of force output, so large suction cups are used to provide maximum adhesion; medium-sized suction cups are used in areas such as the hypothenar eminence and finger base to balance functionality and dexterity; the middle and distal phalanges of the fingers, especially the fingertips of the fourth finger, require delicate touch, so high-density small suction cups are used. This differentiated design allows anti-slip performance to be enhanced where needed and dexterity to be taken into account where it is required, thus achieving the best balance between gripping efficiency and hand comfort overall.

[0048] Furthermore, the palm area also includes: Section 7 is located at the part of the palmar aponeurosis when the glove body is worn on the human hand, and folds are provided on section 7.

[0049] In the above embodiment, the palm portion also includes a seventh section 7, which is located in the middle region covering the palmar aponeurosis when the glove is worn. Unlike the aforementioned sections, the seventh section 7 does not have a suction cup structure, but instead has folds that adapt to hand movements.

[0050] The palmar aponeurosis region is where the skin of the palm forms major folds when the hand is clenched, requiring high flexibility. By incorporating folds instead of suction cups in this area, ample fabric allowance is provided for hand flexion and extension, ensuring that the glove does not cause excessive restriction or pulling during frequent hand gripping and stretching movements. This significantly improves wearing comfort and adaptability for extended work periods.

[0051] Furthermore, the finger area also includes: Section 8 is located at the metacarpophalangeal joints and fingertip joints of the thumb, index finger, middle finger, ring finger and little finger when the glove is worn on the hand. Section 8 has pleats.

[0052] In the above embodiment, joint mobility was also considered for the fingers, and an eighth section 8 was defined. This section corresponds to the location of the metacarpophalangeal joints and fingertip joints of all fingers. Similar to the seventh section 7, the eighth section 8 also has adaptive folds.

[0053] These key joints are the core areas for finger flexion and extension movements. The glove fabric is specially designed with pleats in these locations to ensure that the fingers can bend freely with the joints when gripping tools and performing various operations. This avoids restricting the range of motion of the fingers or accelerating fatigue due to tight fabric, thus ensuring the flexibility and precision of hand movements.

[0054] This application differs from existing technologies that use mechanically distributed anti-slip textures, creatively utilizing ergonomic and kinetic principles. By placing the large suction cup at the point of strong force exertion of the thenar eminence muscle, a vector superposition of muscle contraction force and suction cup negative pressure is achieved, significantly improving grip stability under extreme loads. Simultaneously, the avoidance design for joint creases enhances grip flexibility while meeting 10kV insulation thickness requirements, effectively mitigating the risk of hand muscle strain for workers performing high-altitude power operations. Its main zones are as follows: Zone 1: The thenar eminence strong anchoring zone, corresponding to the thickest muscle group at the base of the thumb (abductor pollicis brevis, opponens pollicis, etc.), is the main source and fulcrum of hand gripping power, and also the area with the greatest contact pressure with the tool. A single, large-diameter, deep-cavity main suction cup is installed here, utilizing the abundant fleshy pads of the thenar eminence as a natural backing, allowing the large suction cup to generate maximum deformation during gripping, forming a core fixed-point suction force and preventing axial slippage of the tool under high torque operation.

[0055] Section 2: The hypothenar eminence auxiliary support area, corresponding to the muscle group on the little finger side of the palm, mainly provides lateral support and prevents rolling during gripping. It is equipped with a group of suction cups with medium diameter and arranged in an arc to provide lateral friction resistance, balance the lever effect, and prevent the insulated rod or heavy tool from rotating in the palm.

[0056] Section 6: Finger-tactile feedback area. The fingertips have a high density of nerves and few muscles, but high flexibility, responsible for fine-tuning. It employs a high-density, micro-pore, matrix-arranged array of small suction cups. These numerous small suction cups can adapt to irregular curved surfaces such as nuts and knobs, much like insect legs. The thin walls of the small suction cups maximize the transmission of tactile signals, addressing the numbness experienced with thick insulating gloves.

[0057] Section 7: Palmar aponeurosis area, located in the center of the palm. The subcutaneous tissue is mostly aponeurosis. When gripping a cylinder, this area often feels suspended, creating a hollow space in the palm. No suction cups are used, or only very shallow drainage textures are provided, to avoid wasting material in non-primary contact areas. The depression in this area serves as a convergence point for drainage / venting channels, preventing the suction cups from becoming submerged and failing due to water accumulation.

[0058] Section 8: Flexion and Wrinkle Avoidance Zone, corresponding to the flexion points of the fingers, is the area where skin folds most frequently. Strictly leave gaps at all joint creases, without any suction cup structures. This eliminates stress concentration, reduces resistance when workers clench their fists, and solves the problem of wrinkles forming at joints in traditional full-textured gloves, leading to finger stiffness and fatigue.

[0059] Section 3: The thumb power zone, which makes it easy for the most powerful thumb to exert force.

[0060] This application provides a schematic diagram of a gripping device, including: a glove body comprising a palm and fingers; and multiple suction cup assemblies of various types, mounted on the glove body. The gripping device provided in this application utilizes suction cups of different sizes and distributions at different locations on the glove body to provide stronger grip in the main force-generating areas of the palm, maintain good tactile feedback in the fine-tuning areas of the fingers, and provide sufficient folds at joint movement points to avoid restriction. This significantly enhances grip stability, especially in sweaty or damp environments, while ensuring hand flexibility and comfort, thereby improving overall work safety and operational efficiency.
