Description

Technical Field

[0001] This utility model relates to the field of forklift technology, and in particular to a forklift top guard. Background Technology

[0002] In traditional forklift overhead guard designs, the protective glass is typically fixed directly to the bracket using adhesive. While this method provides some stability, it becomes difficult to adjust or replace after curing, significantly increasing the difficulty of subsequent repairs and maintenance. To address this issue, existing technologies have proposed using multiple removable pressure plates to fix the protective glass. This solution eliminates the need for adhesives, enabling convenient disassembly of the protective glass and improving maintenance ease. However, during assembly, this method struggles to precisely and evenly control the pressure of each pressure plate on the protective glass, leading to unevenness due to uneven clamping force after fixing. Furthermore, applying excessive locking force during assembly (such as over-locking) can cause localized excessive stress on the protective glass, posing a safety hazard of breakage and failure. Utility Model Content

[0003] In view of the above-mentioned shortcomings of the existing technology, the technical problem to be solved by this utility model is to propose a forklift top guard that is simple in structure, has controllable clamping force and high safety.

[0004] The technical solution adopted by this utility model to solve its technical problem is to provide a forklift top guard, comprising:

[0005] A bracket, wherein the bracket has an opening and a mounting edge arranged circumferentially therein, and the mounting edge has at least one mounting hole;

[0006] A protective assembly, disposed on the opening, comprising a protective glass and a sealing structure, the sealing structure surrounding the periphery of the protective glass and abutting against the mounting edge;

[0007] A fixing component, corresponding to the mounting hole, includes a clamping structure, a limiting structure, and a locking member. The clamping structure abuts against the side of the sealing structure away from the mounting edge. One end of the limiting structure abuts against the mounting edge, and the other end abuts against the side of the clamping structure facing the mounting edge. The height of the limiting structure is equal to the thickness of the sealing structure when it is in the clamped state. The locking member is sequentially inserted into the clamping structure and the limiting structure and is threadedly connected to the mounting hole.

[0008] Furthermore, the clamping structure is provided with a first fixing hole that penetrates itself, and the limiting structure is provided with a second fixing hole that penetrates itself, and the first fixing hole, the second fixing hole and the mounting hole are arranged along the same axis.

[0009] Furthermore, the clamping structure includes a first clamping edge and a second clamping edge that are perpendicularly connected to each other, and the first fixing hole is located in the intersection area of ​​the first clamping edge and the second clamping edge.

[0010] Furthermore, the mounting hole is located outside the projected contour of the sealing structure along the installation direction of the protective glass, and the inner diameters of the first fixing hole, the second fixing hole, and the mounting hole decrease sequentially.

[0011] Furthermore, the clamping structure and the limiting structure are either integrally molded or separate designs.

[0012] Furthermore, both the clamping structure and the limiting structure are sheet metal parts.

[0013] Furthermore, the sealing joint includes a snap-fit ​​portion and an elastic portion. The snap-fit ​​portion has a groove that can be detachably snapped onto the periphery of the protective glass. The opening width of the groove is adapted to the thickness of the protective glass. The elastic portion is located on the side of the snap-fit ​​portion facing the mounting edge and abuts against the mounting edge.

[0014] Furthermore, the elastic part has a built-in sealing cavity; when the sealing structure is subjected to force, the sealing cavity is compressed and deformed, and the elastic part and the mounting edge remain in contact at all times.

[0015] Furthermore, the bracket also includes a positioning edge located at the bottom of the opening, the positioning edge being perpendicularly connected to the mounting edge and abutting against the sealing structure and the clamping structure respectively.

[0016] Furthermore, the mounting holes are provided in two or four locations; when there are two mounting holes, they are located at the two opposite corners of the mounting edge; when there are four mounting holes, they are located at the four corners of the mounting edge, and the number of fixing components is equal to the number of mounting holes and corresponds one-to-one.

[0017] Compared with the prior art, the present invention has at least the following beneficial effects:

[0018] 1. In this utility model, the fixing component corresponds to the mounting hole and includes a clamping structure, a limiting structure, and a locking element. The clamping structure abuts against the side of the sealing structure away from the mounting edge. One end of the limiting structure abuts against the mounting edge, and the other end abuts against the side of the clamping structure facing the mounting edge. The height of the limiting structure is equal to the thickness of the sealing structure when it is in the clamped state. The locking element is sequentially inserted into the clamping structure and the limiting structure and is threadedly connected to the mounting hole. This design precisely controls the compression of the sealing structure through the limiting structure, thereby effectively avoiding unevenness or breakage of the protective glass caused by uneven clamping force or over-tightening, improving assembly consistency and structural safety.

[0019] 2. In this utility model, the clamping structure includes a first clamping edge and a second clamping edge that are perpendicularly connected to each other, and the first fixing hole is located at the intersection of the first clamping edge and the second clamping edge. This design, on the one hand, allows the clamping force to be evenly distributed in two directions, effectively enhancing the support stability of the sealing structure and preventing seal failure or protective glass displacement caused by uneven local stress; on the other hand, by placing the first fixing hole in the intersection area, the reliability of the connection is effectively improved while ensuring structural strength.

[0020] 3. In this utility model, the sealing structure includes a snap-fit ​​part and an elastic part. The snap-fit ​​part has a groove for engaging with the protective glass, the opening width of which is equal to the thickness of the protective glass. The elastic part is located on the side of the snap-fit ​​part facing the mounting edge and abuts against the mounting edge. This design not only achieves convenient assembly between the protective glass and the sealing structure, but also enhances the sealing performance and vibration resistance through the buffering effect of the elastic part, ensuring a good sealing state even under external pressure or vibration. In addition, the continuous contact between the elastic part and the mounting edge also improves the overall structure's waterproof and dustproof capabilities, extending its service life.

[0033] like Figures 1 to 5 As shown, in this embodiment, a forklift top guard includes:

[0034] A bracket 100 has an opening 110, and the opening 110 has a mounting edge 120 arranged circumferentially, and the mounting edge 120 has at least one mounting hole 121.

[0035] A protective assembly is provided on the opening 110, which includes a protective glass 200 and a sealing structure 300, the sealing structure 300 surrounding the periphery of the protective glass 200 and abutting against the mounting edge 120.

[0036] The fixing component, corresponding to the mounting hole 121, includes a clamping structure 400, a limiting structure 500, and a locking element (not shown in the figure). The clamping structure 400 abuts against the side of the sealing structure 300 away from the mounting edge 120. One end of the limiting structure 500 abuts against the mounting edge 120, and the other end abuts against the side of the clamping structure 400 facing the mounting edge 120. The height of the limiting structure 500 is equal to the thickness of the sealing structure 300 when it is in the clamped state. The locking element is sequentially inserted into the clamping structure 400 and the limiting structure 500 and is threadedly connected to the mounting hole 121. This design uses the limiting structure 500 to precisely control the compression of the sealing structure 300, thereby effectively avoiding unevenness or breakage of the protective glass 200 caused by uneven clamping force or over-tightening, improving assembly consistency and structural safety.

[0037] Specifically, such as Figures 1 to 5 As shown, in this embodiment, the bracket 100 is assembled from a top frame, a front frame, and a rear frame. The front frame is arranged at an angle and has a rectangular opening 110 that extends through it to accommodate the protective components, ensuring that the user can clearly observe the external environment through the protective components.

[0038] In this embodiment, the opening 110 has a mounting edge 120 arranged circumferentially therein. The mounting edge 120 is U-shaped, extends toward the center line of the opening 110, and remains parallel to the opening 110 to form a mounting base for supporting and positioning the protective components and fixing components.

[0039] In this embodiment, the mounting edge 120 is provided with at least one mounting hole 121 for mounting the fixing component, thereby achieving a stable connection to the protective component. Preferably, the mounting hole 121 is a circular through hole and is machined into a threaded hole, which facilitates the screwing in of the locking member and its connection with the fixing component, thereby improving the stability of the assembly and the reliability of the connection.

[0040] Preferably, in this embodiment, the mounting hole 121 penetrates the mounting edge 120. This design allows for reliable connection of the fixed component even if the internal thread of the mounting hole 121 fails due to long-term use or other reasons, by inserting a locking member into the mounting hole 121 and tightening it with a nut. This effectively improves the reliability of the connection structure under abnormal working conditions, enhances the overall structural safety and maintainability of the forklift top guard, and extends the product's service life.

[0041] In this embodiment, the mounting hole 121 is located outside the projected contour of the sealing structure 300 along the mounting direction of the protective glass 200. This design avoids opening the mounting hole 121 within the coverage area of ​​the sealing structure 300, thereby effectively protecting the integrity of the sealing structure 300 and preventing sealing failure or local stress concentration problems caused by openings. In addition, placing the mounting hole 121 in the external projected area of ​​the sealing structure 300 helps to improve the convenience of assembly operations and provides sufficient installation space for fixing components, further improving the assembly accuracy and connection reliability of the overall structure.

[0042] In this embodiment, the mounting holes 121 are provided in two or four. The specific choice can be made according to actual usage requirements. Preferably, four mounting holes 121 are provided to achieve better structural stability and uniform clamping.

[0043] When there are two mounting holes 121, they are located on two opposite corners of the mounting edge 120, forming a symmetrical fixing structure. This design is suitable for smaller protective components. While ensuring basic fixing strength and assembly stability, it simplifies the overall structure, reduces the number of parts, and helps to reduce manufacturing costs and improve assembly efficiency.

[0044] When there are four mounting holes 121, they are located at the four corners of the mounting edge 120, forming a four-point support structure. This design enables multi-point clamping of the protective component, making the clamping force distribution more uniform. It is especially suitable for large-sized protective components or those with high requirements for sealing and structural strength. It can effectively prevent glass deformation or breakage caused by uneven local stress, and significantly improve the stability, sealing performance and long-term reliability of the overall structure.

[0045] In this embodiment, the protective component is disposed on the opening 110, and includes a rectangular protective glass 200 and a sealing structure 300. The sealing structure 300 is disposed around the periphery of the protective glass 200 and abuts against the mounting edge 120, thereby forming a reliable sealed connection between the protective glass 200 and the bracket 100, effectively preventing moisture, dust and other impurities from the external environment from entering the driving area, and improving the safety and comfort of the forklift operating environment.

[0046] Preferably, in this embodiment, the sealing structure 300 is detachably wrapped around the periphery of the protective glass 200. This design not only facilitates the assembly and replacement of the protective glass 200, but also allows for the separate replacement of the sealing structure 300 when it ages or is damaged due to long-term use, without the need to replace the entire protective component, thus reducing maintenance costs and improving the maintainability of the structure.

[0047] In this embodiment, the protective glass 200 is a transparent flat glass with a predetermined thickness and strength, preferably tempered glass or laminated safety glass, to meet the requirements for visibility and impact resistance during forklift operation.

[0048] In this embodiment, the sealing structure 300 includes a snap-fit ​​portion 310 and an elastic portion 320. The snap-fit ​​portion 310 has a groove that detachably snaps onto the periphery of the protective glass 200. The opening width of the groove is adapted to the thickness of the protective glass 200, allowing the protective glass 200 to be securely embedded within the groove, thereby achieving quick positioning and detachable connection between the sealing structure 300 and the protective glass 200. This design not only improves assembly efficiency but also facilitates later maintenance and replacement, avoiding the problem of needing to replace the entire protective assembly due to damage to the overall structure.

[0049] In this embodiment, the elastic part 320 is provided on the side of the snap-fit ​​part 310 facing the mounting edge 120 and abuts against the mounting edge 120. Under the pressure applied by the pressing structure 400, it generates elastic deformation. This elastic deformation makes the elastic part 320 fit tightly against the surface of the mounting edge 120, thereby improving the sealing performance between the sealing structure 300 and the bracket 100, preventing external moisture, dust and other impurities from seeping in, and ensuring the cleanliness and safety of the driving area.

[0050] In this embodiment, the elastic part 320 has a built-in sealing cavity 321. When the sealing structure 300 is subjected to pressure from the pressing structure 400, the sealing cavity 321 undergoes compression deformation and enhances the adhesion between the elastic part 320 and the mounting edge 120 through its own rebound characteristics, ensuring that the two always remain in contact. Even under complex working conditions such as vibration and temperature changes, a stable sealing effect can still be maintained. This design significantly improves the environmental adaptability and long-term reliability of the sealing structure 300, while also helping to compensate for assembly errors and reduce dependence on the machining accuracy of the mounting surface, thus possessing good engineering practicality.

[0051] To ensure secure installation of the protective components, this embodiment includes fixing components corresponding to the mounting holes 121. Preferably, the number of fixing components is equal to the number of mounting holes 121, with four sets provided, each corresponding one-to-one with a mounting hole 121, to achieve uniform multi-point clamping. This design not only improves the uniformity of the overall clamping force distribution on the protective components but also enhances the stability and vibration resistance of the connection structure under complex working conditions. It is particularly suitable for applications with large-size protective components or high requirements for sealing and structural strength, effectively preventing glass deformation or breakage caused by uneven local stress, thereby improving the safety and service life of the forklift top guard.

[0052] In this embodiment, the fixing component includes a clamping structure 400, a limiting structure 500, and a locking element. The three work together to ensure that the protective component can maintain a good sealing state and structural integrity when it is affected by external vibration, temperature changes, etc.

[0053] In this embodiment, the pressing structure 400 abuts against the side of the sealing structure 300 away from the mounting edge 120, which is used to apply uniform pressure to the sealing structure 300 to ensure a good sealing fit between it and the mounting edge 120.

[0054] In this embodiment, the clamping structure 400 is L-shaped, including a first clamping edge 420 and a second clamping edge 430 that are perpendicularly connected to each other. Preferably, the first clamping edge 420 and the second clamping edge 430 are integrally formed. This design allows the clamping force to be evenly distributed in two directions, effectively enhancing the support stability of the sealing structure 300 and preventing seal failure or displacement of the protective glass 200 caused by uneven local stress. On the other hand, it can better fit the edge contour of the installation area, improving the overall assembly adaptability.

[0055] In this embodiment, the clamping structure 400 is provided with a first fixing hole 410, preferably a circular through hole, for the locking member to pass through and connect to the bracket 100. The first fixing hole 410 is located at the intersection of the first clamping edge 420 and the second clamping edge 430, which improves the guidance and connection reliability of the locking member during the insertion process while ensuring structural strength.

[0056] In this embodiment, one end of the limiting structure 500 abuts against the mounting edge 120, and the other end abuts against the side of the pressing structure 400 facing the mounting edge 120, thereby limiting the compression of the sealing structure 300 and preventing deformation of the sealing structure 300 or breakage of the protective glass 200 due to excessive compression. Furthermore, the height of the limiting structure 500 is set to match the thickness of the sealing structure 300 under pressure, thus achieving precise control over the compression of the sealing structure 300.

[0057] In this embodiment, the limiting structure 500 is cylindrical and has a second fixing hole 510 that passes through it. This hole is also a circular through hole, which facilitates the insertion of the locking component.

[0058] In this embodiment, the first fixing hole 410, the second fixing hole 510 and the mounting hole 121 are arranged along the same axis, and their inner diameters decrease sequentially to achieve gradual guidance and stable connection of the locking parts from the outside to the inside, thereby improving assembly accuracy and connection consistency.

[0059] In this embodiment, the locking element (not shown in the figure) passes sequentially through the first fixing hole 410 of the pressing structure 400 and the second fixing hole 510 of the limiting structure 500, and is finally screwed into the mounting hole 121 to achieve a firm fixation of the protective component. Preferably, the locking element is a screw or bolt, which has good connection strength and ease of disassembly and assembly, and is suitable for modular assembly and subsequent maintenance.

[0060] In this embodiment, the clamping structure 400 and the limiting structure 500 are either integrally molded or separate designs. Preferably, they are separate designs. This design not only facilitates manufacturing and individual replacement of damaged parts, but also improves the flexibility and maintainability of the overall structure.

[0061] In this embodiment, both the clamping structure 400 and the limiting structure 500 are sheet metal parts. They possess good mechanical strength, processing adaptability, and cost advantages, making them suitable for mass industrial production.

[0062] To improve the ease of installation and positioning accuracy of the protective components, in this embodiment, the bracket 100 further includes a positioning edge 130 disposed at the bottom of the opening 110. This positioning edge 130 is located below the protective component and vertically connected to the mounting edge 120, and abuts against the sealing structure 300 and the clamping structure 400 respectively, allowing the protective component to contact and be initially positioned before being fixed. This design not only effectively guides the protective component to be accurately installed in the preset position, but also avoids problems such as poor sealing or insecure fixing caused by assembly misalignment, significantly improving assembly efficiency and consistency.

[0063] In this embodiment, the bracket 100 further includes a U-shaped limiting edge 140, which is perpendicularly connected to the mounting edge 120 and disposed in the edge region of the opening 110. The two ends of the limiting edge 140 are respectively connected to the two ends of the positioning edge 130, and the two together form a square structure, thereby providing all-round limiting and support for the protective component.
