Description

Technical Field

[0001] This utility model relates to the field of auxiliary components for parts cabinets, specifically to the support structure of parts cabinets. Background Technology

[0002] Parts cabinets are commonly used storage devices in industrial production and daily life, mainly used to store parts, tools, and other items of various specifications, facilitating the classification, management, and retrieval of these items. The supporting structure, as a crucial component of the parts cabinet, directly affects its performance and safety due to its stability and load-bearing capacity.

[0003] Currently, the common support structures for parts cabinets on the market typically employ a simple support leg design, with the support legs directly fixed to the bottom of the cabinet. However, this type of support structure has the following drawbacks: Firstly, it has poor stability, and when heavy parts are placed inside, the cabinet is prone to tilting or even tipping over, posing a safety hazard. Secondly, it has limited load-bearing capacity, and under long-term heavy loads, the support legs are prone to deformation or damage, shortening the lifespan of the parts cabinet. In addition, the height of the support structure is fixed and cannot be adjusted, making it unsuitable for placement on uneven ground, causing the parts cabinet to wobble and affecting the user experience. Utility Model Content

[0004] The purpose of this utility model is to provide a parts cabinet support structure to solve the above problems, as detailed below.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] The parts cabinet support structure provided by this utility model includes two side supports, which are located on both sides and arranged symmetrically. A level body is installed on the outer surface of each side support to support the bottom two sides of the parts cabinet.

[0007] Several counter-pull connection components are combined and arranged between the bottom of the side supports on both sides, so as to adjust the distance between the two side supports so that the two side supports can support parts cabinets with different lateral length dimensions.

[0008] Bottom support components are assembled and installed at both the front and rear positions of the bottom of the side support, which are used to raise and support the parts cabinet.

[0009] The side support is equipped with corner limiting components at both the front and rear external positions to limit and prevent movement of the parts cabinet at the corners.

[0010] Preferably, the side supports are all L-shaped plates arranged longitudinally and have an L-shaped cross-section along the transverse vertical plane, and the level body is a bubble level.

[0011] Preferably, each of the pull-tab connection assemblies includes a pull-tab connecting seat and a pull-tab screw. Several pull-tab connecting seats are vertically fixed on the bottom surface of each side support. The number of pull-tab connecting seats on both sides corresponds and is horizontally aligned. Each pull-tab connecting seat has a mating hole in the horizontal direction. The pull-tab screw is inserted horizontally between each set of horizontally aligned mating holes in a sliding fit manner. At the same time, several limiting nuts are coaxially engaged with the part of the pull-tab screw extending outward from the corresponding pull-tab connecting seat.

[0012] Preferably, the outer surfaces of the pull rods are all Don threads, the number of limiting nuts at the outer ends of the pull rods are two and the directions of rotation are opposite, and the outer ends of the pull rods are all equipped with anti-dislodgement caps in a coaxial threaded manner.

[0013] Preferably, each of the bottom support components includes a support sleeve and a support stud. The support sleeve is vertically fixed at both the front and rear positions of the bottom of the side support. The bottom of the support sleeve is open and the support stud is coaxially installed with the support sleeve by means of threaded engagement. At the same time, the bottom end of each support stud is coaxially fixed with a support end plate with an outer diameter larger than the outer diameter of the support stud.

[0014] Preferably, the bottom surface of the support end plate is coaxially covered and fixed with a non-slip pad of buffer material, and the top surface of the support end plate is coaxially fixed with an external hexagonal force-applying end at the position of the outer periphery of the bottom end of the support stud.

[0015] Preferably, the portion of the support stud extending beyond the bottom end of the support sleeve is coaxially engaged with a locking nut.

[0016] Preferably, each of the corner limiting components includes a mating sleeve and an L-shaped limiting plate. The mating sleeve is fixedly installed longitudinally at the front and rear positions of the outer side of the side support. The number of L-shaped limiting plates corresponds to the number of mating sleeves, and each L-shaped limiting plate slides longitudinally with the corresponding mating sleeve. Each mating sleeve has a mounting hole opened laterally on its outer end face. The mounting holes are all through holes, and each mounting hole has a clamping stud inserted coaxially in a threaded manner. At the same time, each clamping stud can be pressed against the outer surface of the corresponding L-shaped limiting plate.

[0017] Preferably, the horizontal cross-sectional shape of the L-shaped limiting plate is L-shaped, the lateral portions of the L-shaped limiting plates on both sides are close to each other, and the end faces of the lateral portions of the L-shaped limiting plates at the front and rear positions are covered and fixed with buffer plates.

[0018] Preferably, the outer ends of the clamping studs are all coaxially fixed with a gripping end for easy force application and holding, and the inner ends of the clamping studs are all coaxially fixed with an elastic pressure block with an outer diameter smaller than the outer diameter of the clamping stud.

[0019] In practical use, the aforementioned parts cabinet support structure features several counter-pull coupling assemblies arranged between the bottom of the side supports on both sides. Simultaneously, bottom support assemblies are arranged at the front and rear of the bottom of each side support. By using the locking nuts of the counter-pull coupling assemblies to move axially along the support studs, the two side supports can be adjusted to support the bottom sides of the parts cabinet, thus providing elevated support for the cabinet. Simultaneously, the distance between the two side supports can be adjusted, allowing them to adapt to supporting parts cabinets of different lateral lengths, thereby increasing their height. To enhance usability, the support studs and support sleeves of the bottom support assembly are threaded together, allowing for adjustment of the overall vertical dimension of the bottom support assembly. This ensures that the bottom ends of all the bottom support components are grounded, guaranteeing stable placement on uneven surfaces and preventing shaking of the parts cabinet. Furthermore, the external level of the side supports facilitates easy observation and adjustment to a level position, improving the flexibility of the bottom support assembly. The corner limiting components are also integrated at the front and rear positions of the side supports, further enhancing their usability. After securing the bottom side of the parts cabinet, the L-shaped limiting plate of the corner limiting assembly slides longitudinally along the mating sleeve. By tightening the clamping studs, the outer surface of the L-shaped limiting plate is pressed against the bottom corner of the parts cabinet, thus providing corner protection and preventing movement. This enhances the stability of the parts cabinet during use and allows for adjustment of the L-shaped limiting plate's extension position, ensuring the corner limiting assembly can accommodate parts cabinets with varying longitudinal widths, further improving usability. Furthermore, the L-shaped limiting plate of the corner limiting assembly... The method of longitudinally sliding with the fitting sleeve and laterally tightening the clamping stud allows the L-shaped limiting plate and the fitting sleeve to be detachably combined. At the same time, by simply loosening the clamping stud, the L-shaped limiting plate can slide longitudinally and separate from the fitting sleeve, thus enabling the L-shaped limiting plate and the fitting sleeve to be separated. The combination and separation of the L-shaped limiting plate and the fitting sleeve is simple and easy to implement. It facilitates the quick combination of the L-shaped limiting plate and the fitting sleeve to limit and protect the bottom corners of the parts cabinet, and also facilitates the smooth lifting of the parts cabinet away from the side supports on both sides after the L-shaped limiting plate and the fitting sleeve are separated.

[0020] The beneficial effects are as follows: 1. This utility model has several counter-pull connection components combined between the bottom of the side supports on both sides, and bottom support components are combined at the front and rear of the bottom of the side supports. By using the locking nut of the counter-pull connection components to move along the axial direction of the support stud, the two side supports can be adjusted to support the bottom side of the parts cabinet respectively, thereby raising and supporting the parts cabinet with the help of the bottom support components. At the same time, the distance between the two side supports can be adjusted, so that the two side supports can adapt to support parts cabinets with different lateral lengths, thus improving the applicability.

[0021] 2. By using the threaded engagement of the support studs and support sleeves of the bottom support components, the overall vertical dimensions of the bottom support components can be adjusted to extend or retract. This allows the bottom ends of multiple bottom support components to be adjusted to the ground, ensuring stable placement on uneven surfaces and preventing the parts cabinet from shaking during use. At the same time, the external level of the side supports facilitates intuitive observation and adjustment of the side supports to a level position, improving the flexibility of the bottom support components in use.

[0022] 3. Corner limiting components are combined and installed at both the front and rear positions of the side supports. After the side supports support the bottom side of the parts cabinet, the L-shaped limiting plate of the corner limiting component slides longitudinally along the mating sleeve and is tightened by tightening the clamping studs. This allows the outer side of the L-shaped limiting plate to be attached to the bottom corner of the parts cabinet, thus limiting and preventing movement at the corners of the parts cabinet. This helps to improve the stability of the parts cabinet during use. At the same time, the extension position of the L-shaped limiting plate can be adjusted forward and backward to ensure that the corner limiting component can adapt to parts cabinets with different longitudinal widths, further improving its applicability.

[0023] 4. By using the L-shaped limiting plate of the corner limiting component to slide longitudinally with the mating sleeve and tighten the clamping stud laterally, the L-shaped limiting plate and the mating sleeve can be detachably combined. At the same time, by simply loosening the clamping stud, the L-shaped limiting plate can slide longitudinally and separate from the mating sleeve. This allows the L-shaped limiting plate and the mating sleeve to be separated from each other. The combination and separation of the L-shaped limiting plate and the mating sleeve are simple and easy to implement. It is convenient to quickly combine the L-shaped limiting plate and the mating sleeve to limit and protect the bottom corners of the parts cabinet. It is also convenient to separate the L-shaped limiting plate and the mating sleeve to smoothly lift the parts cabinet away from the side supports on both sides. Attached Figure Description

[0036] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0037] See Figures 1-9 As shown, this utility model provides a parts cabinet support structure, including two side supports 2, which are symmetrically arranged on both sides. A level body 3 is mounted on the outer surface of each side support 2 to support the bottom sides of the parts cabinet. Several counter-pull connecting components 4 are combined between the bottoms of the two side supports 2 to adjust the distance between them, allowing the two side supports 2 to support parts cabinets of different lateral lengths. Specifically, each counter-pull connecting component 4 includes a counter-pull connecting seat 404 and a counter-pull screw 402. Several counter-pull connecting seats 404 are vertically fixed to the bottom surface of each side support 2, with the number of counter-pull connecting seats 404 on both sides corresponding to the number of counter-pull connecting seats 404. Furthermore, each of the horizontally aligned tie-down connectors 404 has a mating hole 405, and each set of horizontally aligned mating holes 405 has a tie-down screw 402 inserted horizontally in a sliding fit. At the same time, the portion of the tie-down screw 402 extending outward from the corresponding tie-down connector 404 is coaxially engaged with several limiting nuts 403. The purpose of this arrangement is that, by using the locking nut 502 of the tie-down connection assembly 4 to move axially along the support stud 503, the two side supports 2 can be adjusted to support the bottom side of the parts cabinet, thereby using the bottom support assembly 5 to elevate and support the parts cabinet. At the same time, the distance between the two side supports 2 can be adjusted so that the two side supports 2 can adapt to support parts cabinets with different horizontal length dimensions.

[0038] See Figures 1-8As shown, bottom support components 5 are assembled and installed at both the front and rear positions of the bottom of the side support 2 to elevate and support the parts cabinet. Specifically, each bottom support component 5 includes a support sleeve 501 and a support stud 503. The support sleeve 501 is vertically fixed at both the front and rear positions of the bottom of the side support 2. The bottom of the support sleeve 501 is open and the support stud 503 is coaxially installed with it by means of threaded engagement. At the same time, the bottom end of the support stud 503 is coaxially fixed with a part with an outer diameter larger than that of the support stud 503. The purpose of the diameter support end plate 505 is to allow the overall vertical dimension of the bottom support assembly 5 to be adjusted by means of the threaded engagement between the support stud 503 of the bottom support assembly 5 and the support sleeve 501. This ensures that the bottom ends of multiple bottom support assemblies 5 are all in contact with the ground, ensuring stable placement on uneven surfaces and preventing the parts cabinet from shaking during use. At the same time, in conjunction with the level body 3 outside the side support 2, it is also convenient to visually observe and adjust the side support 2 to a horizontal state.

[0039] See Figures 1-9 As shown, corner limiting components 1 are assembled at the front and rear external positions of the side support 2 to limit and prevent movement of the parts cabinet at the corners. Specifically, each corner limiting component 1 includes a mating sleeve 103 and an L-shaped limiting plate 101. The mating sleeve 103 is fixedly installed longitudinally at the front and rear external positions of the side support 2. The number of L-shaped limiting plates 101 corresponds to the number of mating sleeves 103, and each L-shaped limiting plate 101 slides longitudinally with the corresponding mating sleeve 103. The outer end face of each mating sleeve 103 has a mounting hole 105 opened laterally. The mounting holes 105 are all through holes, and each mounting hole 105 is threaded to the mating sleeve 103. The shaft is inserted with clamping studs 106, and each clamping stud 106 can be clamped onto the outer surface of the corresponding L-shaped limiting plate 101. The reason for this arrangement is that by sliding the L-shaped limiting plate 101 of the corner limiting assembly 1 longitudinally along the mating sleeve 103 and tightening the clamping studs 106, the outer surface of the L-shaped limiting plate 101 can be attached to the bottom corner of the outer perimeter of the parts cabinet. Thus, the corner limiting assembly 1 can be used to limit and prevent movement of the parts cabinet at the corner position. At the same time, the extension position of the L-shaped limiting plate 101 can be adjusted back and forth to ensure that the corner limiting assembly 1 can adapt to parts cabinets with different longitudinal width dimensions.

[0040] See Figures 1-9As shown, the following optimizations have been made to this application. Specifically, the side supports 2 are all L-shaped plates arranged longitudinally, and the cross-sectional shape of the horizontal vertical plane is L-shaped. The level body 3 is a bubble level. This arrangement firstly makes it easier for the design style of the side supports 2 to meet the usage requirements, and secondly, it makes it easier for the level body 3 to be visually observed by the staff. Further optionally, the outer surface of the tie rod 402 is all Tang-style threaded. The number of limiting nuts 403 at the outer end of the tie rod 402 is two and the rotation direction is opposite. The outer end of the tie rod 402 is equipped with anti-loosening caps 401 in a coaxial threaded manner. This arrangement firstly facilitates the Tang-style anti-loosening thread structure formed by the limiting nuts 403 and the tie rod 402, ensuring that the limiting nuts 403 will not loosen accidentally after being tightened and pressed against the surface of the tie rod connecting seat 404. At the same time, the anti-loosening caps 401 prevent the limiting nuts 403 from accidentally detaching and being lost from the end of the tie rod 402.

[0041] See Figures 1-9 As shown, a cushioning anti-slip pad 506 is coaxially covered and fixed to the bottom surface of the support end plate 505. A hexagonal force-applying end 504 is coaxially fixed to the top surface of the support end plate 505 at the outer periphery of the bottom end of the support stud 503. This design facilitates good anti-loosening by allowing the anti-slip pad 506 to directly contact the ground, and also allows for easy tightening of the support stud 503 by using a wrench or other tools to clamp the force-applying end 504. Alternatively, the portion of the support stud 503 extending beyond the bottom end of the support sleeve 501 may be coaxially engaged with a locking nut 502. This prevents the support stud 503 from rotating naturally by tightening the locking nut 502 onto the bottom surface of the support sleeve 501 after the support stud 503 has been tightened until the anti-slip pad 506 is in close contact with the ground.

[0042] See Figures 1-9As shown, the horizontal cross-sectional shape of the L-shaped limiting plate 101 is L-shaped. The lateral portions of the L-shaped limiting plates 101 on both sides are close to each other, and the opposite end faces of the lateral portions of the L-shaped limiting plates 101 at the front and rear positions are covered and fixed with buffer plates 102. The advantage of this arrangement is that the buffer plates 102 can buffer and protect the bottom corners of the parts cabinet by means of the bottom corners of the outer perimeter of the parts cabinet. Optionally, the outer ends of the clamping studs 106 are coaxially fixed with a gripping end 104 for easy force application, and the inner ends of the clamping studs 106 are coaxially fixed with an elastic pressure block 107 with an outer diameter smaller than the outer diameter of the clamping stud 106. This arrangement facilitates the rotation of the clamping studs 106 by hand-tightening the gripping end 104, and also facilitates the stable anti-movement locking of the L-shaped limiting plate 101 by directly pressing the elastic end against the surface of the L-shaped limiting plate 101. Furthermore, the corner limiting component 1 also has the advantage that, through the longitudinal sliding engagement of the L-shaped limiting plate 101 and the mating sleeve 103 and the transverse tightening of the clamping stud 106, the L-shaped limiting plate 101 and the mating sleeve 103 can be detachably combined together. At the same time, by simply loosening the clamping stud 106, the L-shaped limiting plate 101 can slide longitudinally and separate from the mating sleeve 103, thereby enabling the L-shaped limiting plate 101 and the mating sleeve 103 to be separated from each other. The combination and separation of the L-shaped limiting plate 101 and the mating sleeve 103 are simple and easy to implement.

[0043] With the above structure, in practical use, several counter-pull connecting components 4 are combined and arranged between the bottom of the side supports 2 on both sides. At the same time, bottom support components 5 are combined and arranged at the front and rear of the bottom of the side supports 2. By using the locking nuts 502 of the counter-pull connecting components 4 to move axially along the support studs 503, the two side supports 2 can be adjusted to support the bottom side of the parts cabinet respectively. Thus, the bottom support components 5 are used to raise and support the parts cabinet. At the same time, the distance between the two side supports 2 can be adjusted, so that the two side supports 2 can adapt to support parts cabinets with different lateral lengths, thus improving the applicability. The threaded engagement between the support stud 503 and the support sleeve 501 of the bottom support component 5 allows for the adjustment of the overall vertical dimension of the bottom support component 5. This ensures that the bottom ends of all the bottom support components 5 are grounded, guaranteeing stable placement on uneven surfaces and preventing the parts cabinet from wobbling. Furthermore, the external level 3 of the side supports 2 facilitates easy observation and adjustment to a level position, enhancing the flexibility of the bottom support component 5. Since corner limiting components 1 are installed at both the front and rear positions of the side supports 2, after the side supports 2 support the bottom sides of the parts cabinet, the corner limiting components... The L-shaped limiting plate 101 of component 1 slides longitudinally along the mating sleeve 103 and, by tightening the clamping stud 106, ensures that the outer surface of the L-shaped limiting plate 101 is attached to the bottom corner of the parts cabinet. This allows the corner limiting component 1 to provide corner protection and prevent movement of the parts cabinet, improving stability during use. It also allows for adjustment of the extended position of the L-shaped limiting plate 101, ensuring that the corner limiting component 1 can accommodate parts cabinets with different longitudinal widths, further enhancing its applicability. Furthermore, the longitudinal sliding engagement and transverse... By tightening the clamping stud 106, the L-shaped limiting plate 101 and the mating sleeve 103 can be detachably combined. At the same time, by simply loosening the clamping stud 106, the L-shaped limiting plate 101 can slide longitudinally and separate from the mating sleeve 103. This allows the L-shaped limiting plate 101 and the mating sleeve 103 to be separated from each other. The combination and separation of the L-shaped limiting plate 101 and the mating sleeve 103 are simple and easy to implement. It is convenient to quickly combine the L-shaped limiting plate 101 and the mating sleeve 103 to limit and protect the bottom corners of the parts cabinet. It is also convenient to separate the L-shaped limiting plate 101 and the mating sleeve 103 to smoothly lift the parts cabinet away from the side supports 2 on both sides.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should 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.
