Description

Technical Field

[0001] This utility model relates to the field of freezer technology, and more specifically, to a novel anti-collision block. Background Technology

[0002] With the increasing demand for commercial display cabinets in China, numerous problems have emerged during actual use. On the one hand, the power cords of display cabinets often lack effective storage methods, and plugs are often not properly placed. This not only affects ease of use but can also lead to tangled and worn power cords, posing safety hazards. For example, in some supermarkets or convenience stores, multiple commercial display cabinets are used together, with power cords intertwined, making management difficult and increasing the risk of damage to the cord sheaths due to trampling or pulling, potentially causing short circuits and other electrical faults, and in severe cases, even fires. On the other hand, when display cabinets are pushed against walls, the back panel is easily damaged by impacts from foreign objects on the wall surface, reducing the cabinet's lifespan and increasing operating costs. During routine handling or repositioning, careless operation can cause the back panel to collide with hard objects such as wall sockets or corners, resulting in dents, scratches, and even damage to the internal insulation layer, affecting the cabinet's cooling performance.

[0003] Currently available anti-collision blocks on the market have relatively limited functions, mostly providing only basic anti-collision capabilities. For example, a collision-resistant component for a horizontal refrigerated display case disclosed in patent CN205503846U achieves basic anti-collision by inserting anti-collision strip plugs into the plug slots of the anti-collision strips and then applying adhesive to the bottom of the buffer body to attach it to the outer liner of the refrigerated display case, but without any additional functions. Furthermore, the installation method is not flexible enough. Some anti-collision blocks are installed on the cabinet body, and if users want to remove them later, they often need to use tools such as screwdrivers, which is inconvenient. For example, an automatic anti-collision and shockproof display case with patent CN211269636U has a relatively fixed connection between its anti-collision structure and the cabinet body; adjusting or removing it requires considerable time and effort. In addition, existing anti-collision blocks generally lack storage functions and cannot be effectively integrated with protective covers, failing to meet the modern user's demand for multifunctional and convenient display cases. In contrast, this new type of anti-collision block not only achieves a highly efficient anti-collision effect, but also integrates functions such as power cord storage, plug placement, and flexible connection with the protective cover through ingenious design, bringing great convenience and practicality to the use of commercial display cabinets. Utility Model Content

[0004] The purpose of this utility model is to provide a new type of anti-collision block to solve the problem mentioned in the background art that when the display cabinet is pushed to the base of the wall, the back panel of the display cabinet is easily damaged by impact due to the presence of foreign objects on the wall surface, which reduces the service life of the display cabinet and increases the cost of use.

[0005] To achieve the above objectives, this utility model provides a novel anti-collision block, comprising an anti-collision block body and a rear cover; the anti-collision block body is detachably connected to the outer side of the rear cover via a snap-fit ​​structure; the anti-collision block body has a plug receiving groove for accommodating the power cord plug of a commercial refrigerator / freezer; the rear cover is fixedly provided with at least one hook for storing the power cord, and the edge of the rear cover away from the anti-collision block body is provided with a mounting hole, in which a fastening bolt is disposed, and the fastening bolt installs the rear cover onto the commercial refrigerator / freezer body.

[0006] This design utilizes a combination of "anti-collision block body + rear cover" to create a "functionally integrated" design logic: First, a snap-fit ​​structure allows for detachable connection between the anti-collision block body and the rear cover, enabling assembly and disassembly without additional tools thanks to the snap-fit's elastic interlocking properties. Second, a plug receiving slot is provided in the anti-collision block body, achieving precise storage by matching the shape of the slot with the plug based on the principle of "shape adaptation." Finally, the rear cover uses a "bolt fixing" principle, with the mounting holes and the threaded engagement of the bolts to stably fix the entire structure to the commercial refrigeration and freezing cabinet, while the power cord is suspended and stored using a hook-based physical support structure.

[0007] Preferably, the shape of the plug receiving groove is adapted to the shape of the power cord plug, and the inner wall of the plug receiving groove is provided with anti-slip protrusions.

[0008] This design is based on a dual design principle of "shape adaptation + friction anti-slip": on the one hand, the shape of the plug receiving slot is adapted to the shape of the power cord plug, and the gap between the plug and the slot is reduced by "contour fitting" to prevent the plug from shaking in the slot; on the other hand, anti-slip protrusions are set on the inner wall of the slot, which increase the contact friction between the plug and the slot. Based on the principle of "friction mechanics", the protrusions offset the impact of external forces such as equipment handling and slight vibration on the plug and prevent the plug from slipping off.

[0009] Preferably, the hooks are spaced apart along the top side of the rear cover.

[0010] This setup follows the principle of "space optimization + orderly storage": hooks are spaced out along the top side of the rear cover. On the one hand, this utilizes the unused space at the top of the rear cover, avoiding the occupation of the surrounding floor or side space of the display case; on the other hand, the spaced layout forms "multi-level storage points". Depending on the length of the power cord, you can choose to hang it with a single hook (short power cord) or hang it with multiple hooks wrapped around it (long power cord), achieving orderly organization of the power cord through physical separation.

[0011] Preferably, the buckle structure includes an elastic hook disposed on the side of the anti-collision block body facing the rear guard, and a locking hole disposed at the corresponding position of the rear guard; the end of the elastic hook is provided with a guide slope, the edge of the locking hole is provided with a mating slope adapted to the guide slope, and the number of elastic hooks is at least two, symmetrically distributed along the length direction of the anti-collision block body.

[0012] This setup is based on the mechanical structure principle of "sloping guide + symmetrical force": First, the guide slope at the end of the elastic hook and the mating slope of the locking hole form a "wedge-shaped guide structure". During installation, the slopes fit together, converting the vertical pressing force into the lateral deformation force of the elastic hook, reducing the locking resistance. Second, at least two elastic hooks are symmetrically distributed along the length of the anti-collision block body. Based on the principle of "force balance", it ensures that the force on both ends of the anti-collision block body is uniform when the buckle is connected, avoiding tilting or loosening caused by unilateral force.

[0013] Preferably, the inner wall of the plug receiving groove is also provided with an insulating buffer layer, which is made of silicone rubber and has a thickness of 0.5-1.5mm.

[0014] This design combines the material properties of "insulation protection + cushioning and shock absorption": First, silicone rubber has excellent electrical insulation properties. Based on the principle of "insulation barrier," a silicone rubber insulating buffer layer is placed on the inner wall of the plug receiving slot to block the conduction path of possible leakage current from the plug to the anti-collision block itself. Second, silicone rubber has good elastic deformation capability. Based on the principle of "buffering and energy absorption," when there is an external collision or the plug is inserted, the buffer layer absorbs the impact force through deformation, reducing the direct force on the plug. At the same time, the 0.5-1.5mm thickness design ensures insulation and cushioning effects while avoiding excessive thickness that would prevent the plug from being inserted smoothly.

[0015] Preferably, the anti-collision block body is made of high-density polyethylene material with a density of 0.94-0.96 g / cm³, and the outer surface of the anti-collision block body is provided with a wear-resistant coating made of polytetrafluoroethylene material with a coating thickness of 0.3-0.8 mm; the thickness of the anti-collision block body is 15-30 mm, the length is 80-150 mm, and the width is 50-100 mm.

[0016] This design is based on a comprehensive principle of "material characteristics + size adaptation": First, high-density polyethylene (density 0.94-0.96g / cm³) has high strength and high toughness, and based on the principle of "impact resistance and energy absorption," it can effectively absorb impact force as the main material of the anti-collision block. Second, the wear-resistant coating of polytetrafluoroethylene has an extremely low coefficient of friction and excellent wear resistance, and based on the principle of "surface protection," it forms a protective layer on the outer surface of the block to resist daily friction. Finally, the thickness of 15-30mm (ensuring anti-collision strength), the length of 80-150mm, and the width of 50-100mm (adapting to most freezer cabinet sizes) are based on the principle of "size matching," balancing the anti-collision effect with the installation space requirements.

[0017] Preferably, after the anti-collision block body is connected to the rear guard, the distance between the outer side of the anti-collision block body and the outer side of the rear guard is 10-25mm; the depth of the plug receiving groove is 20-40mm, the width is 15-30mm, and the length is 30-60mm.

[0018] This design is based on the principle of "priority buffering + space adaptation": First, the outer side of the anti-collision block extends 10-25mm beyond the outer side of the rear guard, forming a "protruding buffer layer." Based on the principle of "priority contact," when the freezer is close to a wall or hard object, the protruding anti-collision block contacts the back panel of the freezer before the rear guard, ensuring that the impact force is completely absorbed by the anti-collision block. Second, the plug receiving slot has a depth of 20-40mm (ensuring the plug is fully inserted), a width of 15-30mm, and a length of 30-60mm (adapting to most commercial power cord plug sizes). Based on the principle of "shape adaptation," this ensures that the plug is not exposed or loose after being inserted.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: This new type of anti-collision block uses high-density polyethylene (0.94-0.96 g / cm³) as its main body. This material has excellent toughness and impact resistance. Combined with a thickness of 15-30 mm, it can effectively absorb the impact force generated when the display case collides with walls or hard objects. Furthermore, after the anti-collision block is connected to the rear cover, its outer surface extends 10-25 mm beyond the outer surface of the rear cover, forming a "priority contact buffer layer." This directly blocks external impacts from affecting the rear panel of the display case, preventing dents, scratches, or damage to the insulation layer. This significantly reduces repair costs caused by impacts and extends the overall lifespan of the equipment.

[0020] The anti-collision block features a plug-receiving groove (20-40mm deep, 15-30mm wide, 30-60mm long) shaped to fit the power cord plug of commercial refrigerated and frozen cabinets, precisely accommodating the plug and preventing loss, damage, or dust accumulation due to careless placement. Simultaneously, anti-slip protrusions on the inner wall of the groove increase friction between the plug and the groove, preventing the plug from slipping during equipment handling or minor vibrations. A 0.5-1.5mm thick silicone rubber insulating buffer layer on the inner wall further secures the plug, isolates current conduction to prevent safety risks caused by plug leakage, and cushions the impact of external collisions, protecting the internal wiring of the plug.

[0021] The hooks spaced apart on the top side of the rear cover allow for flexible adjustment of the storage position according to the length of the power cord. This neatly winds up and hangs long power cords, preventing wear and tear, knots, or breakage and short circuits caused by stepping or pulling. This storage design keeps the space around the display case tidier and facilitates quick wiring inspection by staff, improving equipment maintenance efficiency. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides a novel anti-collision block, such as Figure 1 , Figure 2 , Figure 3 As shown, it includes a crash block body 1 and a rear cover 2; the crash block body 1 is detachably connected to the outer side of the rear cover 2 via a snap-fit ​​structure 3; the crash block body 1 is provided with a plug receiving slot 11 for accommodating the power cord plug of the commercial refrigerator / freezer; at least one hook 21 for storing the power cord is fixedly provided on the rear cover 2; the rear cover 2 is provided with a mounting hole 22 on the edge away from the crash block body 1, and a fastening bolt 23 is provided in the mounting hole 22, which secures the rear cover 2 to the commercial refrigerator / freezer body.

[0025] Breaking away from the limitations of traditional anti-collision blocks that only provide "single-function protection," this design combines the anti-collision block body 1 with the rear cover 2 to simultaneously achieve three major functions: anti-collision protection, plug storage in the plug receiving slot 11, and power cord organization in the hook 21. This addresses the core pain points of commercial refrigerated and frozen cabinets: "easily damaged rear panel, messy power cords, and nowhere to put plugs." The snap-fit ​​structure 3 allows the anti-collision block body 1 to be independently disassembled and installed, enabling users to flexibly operate according to their needs, such as cleaning, replacement, or temporary removal. The fastening bolts 23 and the mounting holes 22 ensure a secure connection between the rear cover 2 and the cabinet, preventing loosening over time. This design provides a basic framework for subsequent optimizations of the plug receiving slot 11, hook 21, and other structures, as well as for material upgrades to the anti-collision block body 1, ensuring the stability and scalability of the overall design.

[0026] In this embodiment, as Figure 1 , Figure 2 , Figure 3 As shown, the shape of the plug receiving groove 11 is adapted to the shape of the power cord plug, and the inner wall of the plug receiving groove 11 is provided with anti-slip protrusions 12.

[0027] The combination of the fitting shape of the plug receiving slot 11 and the anti-slip protrusions 12 ensures that the plug is "precisely positioned and firmly fixed" within the plug receiving slot 11, avoiding the loss, damage, or dust accumulation caused by the traditional random placement of plugs. The plug can be smoothly inserted into the plug receiving slot 11 without repeated adjustments, and can be directly plugged in and unplugged when needed, reducing operation steps, which is especially suitable for high-frequency use scenarios such as supermarkets and convenience stores. The anti-slip protrusions 12 prevent the plug from being worn due to collisions with the inner wall of the plug receiving slot 11 caused by shaking, extending the service life of the plug and reducing the risk of power outages caused by plug damage.

[0028] Specifically, such as Figure 1 , Figure 2 As shown, hooks 21 are spaced apart along the top side of the rear cover 2.

[0029] To prevent power cords from becoming tangled on the ground or under equipment, reducing the risk of damage to the outer sheath and breakage of the power cords due to being stepped on or pulled, thus lowering the safety hazards such as short circuits, the orderly layout of hooks 21 makes the space around the rear cover 2 more organized. The power cords neatly stored on hooks 21 make it easier for staff to quickly troubleshoot line problems without having to untangle tangled cables, saving maintenance time. The spaced hooks 21 can accommodate power cords of different lengths, eliminating the need to adjust the design of the hooks 21 on the rear cover 2 for specific cable lengths, thus improving the product's applicability.

[0030] Furthermore, such as Figure 4 As shown, the buckle structure 3 includes an elastic hook 31 disposed on the side of the anti-collision block body 1 facing the rear guard 2, and a buckle hole 32 opened at the corresponding position of the rear guard 2; the end of the elastic hook 31 is provided with a guide slope 311, and the edge of the buckle hole 32 is provided with a mating slope 321 adapted to the guide slope 311, and the number of elastic hooks 31 is at least two, which are symmetrically distributed along the length direction of the anti-collision block body 1.

[0031] The design of the guide slope 311 and the mating slope 321 allows the anti-collision block body 1 to be installed without the need for precise alignment of the elastic hooks 31 and the locking holes 32. Simply press to engage. When disassembling, gently pry the elastic hooks 31 to separate the anti-collision block body 1 from the rear guard 2. No screwdrivers or other tools are required, making the operation extremely easy. The symmetrically distributed elastic hooks 31 ensure that the anti-collision block body 1 and the rear guard 2 are tightly connected by the buckle structure 3. Even if subjected to impact or vibration, the elastic hooks 31 on one side will not fall off or loosen, ensuring the stability of the anti-collision function of the anti-collision block body 1. The sloped guide reduces mechanical wear when the elastic hooks 31 and the locking holes 32 are engaged. The symmetrical force on the elastic hooks 31 avoids local stress concentration in the anti-collision block body 1, extends the service life of the buckle structure 3, and reduces the frequency of component replacement.

[0032] Furthermore, such as Figure 3As shown, the inner wall of the plug receiving groove 11 is also provided with an insulating buffer layer 111, which is made of silicone rubber and has a thickness of 0.5-1.5mm.

[0033] The insulating buffer layer 111 completely isolates the risk of leakage, making it especially suitable for humid environments with multiple devices using electricity in commercial settings, ensuring the safety of personnel and equipment. Its combination with the anti-collision block body 1 provides more comprehensive protection. The insulating buffer layer 111 reduces the collision and wear between the plug and the inner wall of the plug receiving slot 11, preventing the plug shell from cracking or the internal wiring from loosening, thus extending the plug's service life. The elastic insulating buffer layer 111 allows the plug to fit more snugly when inserted into the plug receiving slot 11 and to be removed more smoothly, while also reducing noise during insertion and removal and improving operational comfort.

[0034] Furthermore, the anti-collision block body 1 is made of high-density polyethylene material with a density of 0.94-0.96 g / cm³, and the outer surface of the anti-collision block body 1 is provided with a wear-resistant coating made of polytetrafluoroethylene material with a coating thickness of 0.3-0.8 mm; the thickness of the anti-collision block body 1 is 15-30 mm, the length is 80-150 mm, and the width is 50-100 mm.

[0035] The high-density polyethylene (HDPE) anti-collision block body 1 is highly tough, ensuring it is not easily broken upon impact. Its 15-30mm thickness provides ample buffer space, effectively protecting the rear panel of the freezer from impact damage. A PTFE (polytetrafluoroethylene) wear-resistant coating covers the outer surface of the anti-collision block body 1, resisting friction and scratches, preventing surface aging and damage, and maintaining appearance and performance even after long-term use, reducing replacement costs. The 180-150mm length and 50-100mm width of the anti-collision block body 1 are compatible with the dimensions of most commercial refrigerated and frozen freezers, allowing for easy assembly and installation of the rear cover 2 and anti-collision block body 1 without customization, thus improving the product's market applicability.

[0036] Furthermore, after the anti-collision block body 1 is connected to the rear guard 2, the distance between the outer side of the anti-collision block body 1 and the outer side of the rear guard 2 is 10-25mm; the depth of the plug receiving groove 11 is 20-40mm, the width is 15-30mm, and the length is 30-60mm.

[0037] The protruding anti-collision block body 1 ensures that the impact force is not transmitted to the rear panel of the freezer, avoiding dents, scratches, or damage to the insulation layer, thus extending the service life of the freezer. The support of the rear cover 2 makes the cushioning of the anti-collision block body 1 more stable. The plug receiving groove 11 with a depth of 20-40mm, a width of 15-30mm, and a length of 30-60mm allows the plug to be fully embedded, avoiding accidental collisions or accidental unplugging caused by exposed plugs, while also reducing the accumulation of dust in the plug receiving groove 11. The outer side of the anti-collision block body 1 extends 10-25mm beyond the outer side of the rear cover 2, ensuring the anti-collision effect while avoiding excessive space occupation, allowing the freezer to be placed close to the wall, saving space in commercial spaces.

[0038] When using the novel anti-collision block of this utility model, first refer to Figures 1 and 2, and attach the rear cover 2 to the preset installation position on the commercial refrigerated and frozen cabinet body, aligning the mounting holes 22 on the edge of the rear cover 2 with the reserved holes on the cabinet body. Then, insert the fastening bolts 23 into the mounting holes 22, and tighten the bolts clockwise using the thread engagement principle until the rear cover 2 is tightly fitted to the cabinet body without any looseness, thus completing the fixation of the basic installation carrier. Referring to Figure 4, hold the anti-collision block body 1 and align the elastic hook 31 on one side with the locking hole 32 on the rear guard 2. Since the end of the elastic hook 31 has a guide slope 311 and the edge of the locking hole 32 has a matching mating slope 321, when the anti-collision block body 1 is pressed, the two slopes fit together, converting the vertical pressure into the lateral deformation force of the elastic hook 31. Continue pressing until the elastic hook 31 is fully engaged in the locking hole 32. At this point, the elastic hook 31 recovers its deformation and forms a mechanical engagement with the locking hole 32, stably connecting the anti-collision block body 1 to the rear guard 2 (the symmetrically distributed elastic hooks 31 ensure balanced force and prevent the anti-collision block body 1 from tilting). After installation, check whether the opening orientation of the plug receiving slot 11 (Figure 3) is convenient for inserting the plug, and whether the hooks 21 (Figure 1, Figure 2) are spaced along the top side of the rear guard 2 and are not deformed, to ensure that the subsequent storage function can be used normally; at the same time, confirm that the outer side of the anti-collision block body 1 extends 10-25mm beyond the outer side of the rear guard 2 to form a "priority buffer area" to prepare for the anti-collision function. When a commercial refrigerated freezer is pushed against a wall or comes into contact with a hard object, the protruding anti-collision block body 1 (rather than the rear panel of the cabinet) will be the first part to impact the wall / hard object. Because the anti-collision block body 1 is made of high-density polyethylene (density 0.94-0.96 g / cm³, thickness 15-30 mm), its high toughness allows it to absorb impact force through its own deformation, preventing the impact force from being directly transmitted to the rear panel of the cabinet. Simultaneously, the polytetrafluoroethylene wear-resistant coating (thickness 0.3-0.8 mm) on the outer surface of the anti-collision block body 1 can resist friction and scratches during collisions, preventing surface damage and ensuring long-term impact protection. If the impact force is large, the rear cover 2, securely connected to the cabinet body by fastening bolts 23, can help disperse the impact force borne by the anti-collision block body 1, further reducing the risk of damage to the rear panel of the cabinet. Plug Storage: After use, align the power cord plug of the commercial refrigerator / freezer with the plug receiving slot 11 (Figure 3) on the anti-collision block body 1 and insert it. Since the shape of the plug receiving slot 11 is adapted to the plug shape (depth 20-40mm, width 15-30mm, length 30-60mm), the plug can be completely embedded in the slot; the anti-slip protrusions 12 (Figure 2) on the inner wall of the slot increase the friction between the plug and the slot wall, preventing the plug from slipping off due to slight vibration of the cabinet or accidental contact; at the same time, the 0.5-1.5mm thick silicone rubber insulating buffer layer 111 (Figure 3) on the inner wall of the slot can wrap the plug, which not only isolates the possible leakage current of the plug (avoiding safety hazards), but also buffers the impact of external collisions on the plug through elastic deformation, protecting the plug shell and internal circuitry. Power cord organization: Hang excess power cords by winding them around hooks 21 (Figures 1 and 2). Short power cords can be hung directly on a single hook 21, while long power cords can be wound sequentially around multiple spaced hooks 21, achieving orderly storage of power cords. This design avoids power cords being piled up messily on the ground or at the bottom of the cabinet, reducing damage to the outer sheath and breakage of the power cords caused by stepping or pulling, while keeping the space around the cabinet tidy and facilitating staff inspection. When it is necessary to clean the surface stains of the bumper block body 1 or replace a damaged bumper block body 1, no tools are required. Simply use your hands to gently pry open the elastic hooks 31 on both sides of the bumper block body 1 (Figure 4) – apply a slight force outward to deform the elastic hooks 31, disengaging them from the locking holes 32, and the bumper block body 1 can be removed from the rear cover 2. After cleaning, re-lock it according to the steps of "Installation Stage 2", or replace it with a new bumper block body 1. The operation is convenient and does not affect the fixed state of the rear cover 2 and the housing. If it is necessary to maintain the hook 21 (such as to correct a deformed hook 21) or check the connection status between the mounting hole 22 and the fastening bolt 23, the fastening bolt 23 can be loosened with a screwdriver, the back cover 2 can be removed for maintenance, and then it can be re-secured with bolts after maintenance.
