Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of outdoor activity equipment, and in particular to a desktop extension module and desktop component. Background Technology
[0002] Outdoor activities are becoming increasingly popular, and spider stoves are a common piece of equipment used during these activities. However, how to safely and securely restrain spider stoves has become a pressing issue that needs to be addressed in practical use.
[0003] Traditionally, the spider stove is simply placed on a regular tabletop. This method has significant drawbacks: regular tabletops lack dedicated support structures, making the spider stove prone to sliding or even tipping over due to external forces or uneven surfaces. This not only affects the user experience but also potentially leads to safety accidents such as burns. Therefore, existing technologies urgently need improvement to address these issues.

[0004] The purpose of this invention is to provide a desktop expansion module and desktop components to solve the problem of unstable device placement during outdoor activities.
[0005] To solve the above-mentioned technical problems, this utility model provides a desktop extension module and desktop components.
[0006] The desktop extension module of this utility model includes: The connector is used to connect to the desktop; At least two parallel spaced support rails are provided, the support rails are fixedly connected to the connecting part, each support rail is provided with a slider and a stop, the stop is fixedly set on the support rail, the slider is guided and slidably set on the support rail, and the slider is used to cooperate with the stop to fix the constrained object; Constraints are used to constrain the position of sliders to fix the constrained object.
[0007] Furthermore, a first slot for limiting the constrained object is formed between the stop block and the support guide rail, and a second slot for limiting the constrained object is formed between the slider and the support guide rail.
[0008] Furthermore, the constraint element is a spring, which is used to bring the slider closer to the stop to fix the constrained object.
[0009] Furthermore, the spring is a tension spring, with one end fixedly connected to the slider and the other end fixedly connected to the stop.
[0010] Furthermore, the spring is a compression spring, with one end of the compression spring fixedly connected to the slider and the other end fixedly connected to the connecting part.
[0011] Furthermore, it also includes a guide rod, one end of which is fixedly connected to the connecting part and the other end of which is fixedly connected to the support guide rail. The compression spring is sleeved on the guide rod, and the slider has a through hole through which the guide rod passes.
[0012] Furthermore, the slider is provided with a pulley groove, and a guide pulley that rolls along the support rail is provided in the pulley groove.
[0013] The desktop component of this utility model includes a desktop and a desktop extension module as described in any of the above technical solutions, wherein the desktop extension module is connected to the desktop.
[0014] Furthermore, the desktop extension module is fixedly connected to the desktop via a connector.
[0015] Furthermore, the desktop has a guide groove extending in the horizontal direction, and the connecting part has a guide block adapted to the guide groove. The guide groove is used to support the connecting part in the vertical direction and to allow the guide block to slide in the horizontal direction.
[0016] Compared with the prior art, the present invention has at least the following beneficial effects: By cooperating with the adjustable slider and fixed stop, this device can accommodate objects of different sizes, such as spider stoves, high-altitude gas canisters and burners, or water pumps. It can also be used for other items with leg structures, such as portable gas stoves and portable gas cooktops. Furthermore, it can be used to secure outdoor audio equipment, portable projectors, small toolboxes, and other items that may slide due to external forces, as long as their bottom structure (such as legs, frames, etc.) matches the constraint mechanism of this application. In use, the object to be constrained is placed on the support rail, and the slider is slid to clamp and fix the object together with the stop. The parallel rail design increases support stability and is suitable for scenarios requiring horizontal fixation. The constraint provides continuous pressure to prevent the slider from shifting, thereby preventing the object from tipping over. Compared to directly placing the object on a table, this structure provides a more reliable fixation method, solving the problem of unstable equipment placement during outdoor activities.

It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.
[0024] The following is in conjunction with the instruction manual appendix. Figure 1 To be continued Figure 12 This paper introduces the desktop extension module and desktop components of this utility model.
[0025] like Figure 1 , Figure 2 and Figure 3As shown, the desktop extension module of this application includes a connecting part 10, a support rail 20, and a constraint member. The connecting part 10 is used to connect to the desktop 30. The support rail 20 is fixedly connected to the connecting part 10. Each support rail 20 is provided with a slider 40 and a stop 50. The stop 50 is fixedly disposed on the support rail 20, and the slider 40 is guided and slidably disposed on the support rail 20. The slider 40 is used to cooperate with the stop 50 to fix the constrained object. The constraint member is used to constrain the position of the slider 40 to fix the constrained object.
[0026] By cooperating with the adjustable slider 40 and the fixed stop 50, it can accommodate constrained objects of different sizes, such as the spider furnace 70, or... Figure 4 The high-altitude gas cylinder 71 and stove 72 shown are, or as... Figure 5 The water pump 73 shown needs to be used with a clamp 74 that can support the high-altitude gas tank 71 or the water pump 73. Other items with support legs, such as portable gas stoves or portable gas cooktops, can also be used. Furthermore, it can be used to secure outdoor audio equipment, portable projectors, small toolboxes, and other items that may slide due to external forces, as long as their bottom structure (such as legs, frames, etc.) is compatible with the constraint mechanism of this application.
[0027] In use, the object to be constrained is placed on the support rail 20, and the sliding slider 40, together with the stop block 50, clamps and fixes the object. The parallel rail design increases support stability and is suitable for scenarios requiring horizontal fixation. The constraint provides continuous pressure to prevent the slider 40 from shifting, thereby preventing the object from tipping over. Compared to placing the object directly on the tabletop 30, this structure provides a more reliable fixing method, solving the problem of unstable equipment placement during outdoor activities.
[0028] Furthermore, in some of these embodiments, such as Figure 1 As shown, a first slot 21 for limiting the constrained object is formed between the stop block 50 and the support guide rail 20, and a second slot 22 for limiting the constrained object is formed between the slider 40 and the support guide rail 20.
[0029] Specifically, the first slot 21 is formed by the gap between the stop 50 and the support rail 20, the size of which matches the thickness of the constrained object, allowing the constrained object to be stably engaged within it. The second slot 22 is formed by the gap between the slider 40 and the support rail 20, the gap also matching the thickness of the constrained object. As a preferred embodiment, the opening directions of the first slot 21 and the second slot 22 are opposite, thereby limiting the constrained object from two directions. Furthermore, the inner surface of the slots can be provided with anti-slip textures or rubber pads to increase friction and prevent the constrained object from sliding.
[0030] By setting up the first and second locking slots 21 that cooperate with each other, the constrained object can be limited from multiple directions, effectively preventing displacement or loosening of the constrained object during the fixing process. Specifically, in fixing the spider furnace 70, by simultaneously locking the legs of the spider furnace 70 into the first and second locking slots 21, the risk of tipping over due to external force can be avoided, ensuring safety during use.
[0031] Furthermore, in some embodiments, the constraint element is a spring, which is used to bring the slider 40 closer to the stop 50 to fix the constrained object.
[0032] The automatic reset and clamping function of slider 40 is achieved by using the elastic force of a spring, which solves the problems of inconvenience in manually adjusting the position of slider 40 and difficulty in maintaining a stable clamping force. Using a spring as a constraint component simplifies the operation steps, improves the reliability and consistency of clamping, and is simple in structure, easy to implement and maintain.
[0033] Preferably, in some of these embodiments, such as Figure 1 and Figure 2 As shown, the spring is a tension spring 61, one end of which is fixedly connected to the slider 40, and the other end is fixedly connected to the stop block 50.
[0034] Specifically, the tension spring 61, acting as an elastic constraint, is fixed at both ends to the slider 40 and the stop 50, respectively. When the slider 40 slides along the support guide rail 20, the tension spring 61 is stretched and generates an elastic restoring force. This restoring force causes the slider 40 to move towards the stop 50, thereby firmly fixing the constrained object to the support guide rail 20. In a preferred embodiment, the tension spring 61 can be made of stainless steel, with its two ends connected to the connecting holes on the slider 40 and the stop 50 via hooks or retaining rings, respectively. Furthermore, the elastic coefficient of the tension spring 61 can be adjusted according to the weight of the constrained object to ensure that the slider 40 can stably fix objects of different weights. For example, a tension spring 61 with a larger elastic coefficient can be used for heavier objects, while a tension spring 61 with a smaller elastic coefficient can be used for lighter objects.
[0035] The elasticity of the tension spring 61 allows the slider 40 to automatically approach the stop 50, thus firmly fixing the constrained object to the support rail 20. This solution has a simple structure, is easy to install, and can adapt to the fixing needs of objects of different weights. Specifically, the elasticity of the tension spring 61 allows the slider 40 to automatically adjust its position without manual operation, improving ease of use and safety. Furthermore, since the tension spring 61 is always in a stretched state, it can continuously provide constraint force, ensuring that the constrained object remains stable when subjected to external forces.
[0036] In other embodiments, such as Figure 6 As shown, the constraint can also be an elastic rope 64, that is, the tension spring 61 is replaced by an elastic rope 64, one end of the elastic rope 64 is fixedly connected to the slider 40, and the other end is fixedly connected to the stop block 50.
[0037] Preferably, in some of these embodiments, such as Figure 7 As shown, the spring is a compression spring 62, one end of which is fixedly connected to the slider 40, and the other end is fixedly connected to the connecting part 10.
[0038] The compression spring 62 is a compression spring that generates elastic force through compression deformation. Specifically, the compression spring 62 can adopt a helical spring structure, and the elastic coefficient can be adjusted according to the weight of the constrained object. As a preferred embodiment, the compression spring 62 is made of stainless steel to provide good corrosion resistance.
[0039] The elastic force of the compression spring 62 causes the slider 40 to tend to move towards the connecting part 10. When the constrained object is placed between the slider 40 and the stop block 50, the elastic force of the compression spring 62 pushes the slider 40 to press the constrained object, thereby achieving a stable fixation. By adjusting the pre-compression amount of the compression spring 62, the clamping force on the constrained object can be flexibly adjusted to meet the fixing needs of objects of different sizes.
[0040] In other embodiments, the constraint member may also be a set screw provided on the slider 40, that is, after the slider 40 moves into place, the set screw is used to press against the support guide rail 20 to prevent the slider 40 from sliding.
[0041] Furthermore, in some of these embodiments, such as Figure 7 As shown, it also includes a guide rod 63, one end of which is fixedly connected to the connecting part 10 and the other end is fixedly connected to the support guide rail 20. The compression spring 62 is sleeved on the guide rod 63, and the slider 40 has a through hole through which the guide rod 63 passes.
[0042] The guide rod 63 can be made of metal, such as stainless steel or aluminum alloy, and its diameter matches the inner diameter of the compression spring 62 to ensure stable mounting of the compression spring 62. A perforation is machined into the slider 40, with the hole diameter slightly larger than the diameter of the guide rod 63 to allow the slider 40 to slide axially along the guide rod 63. In a preferred embodiment, both ends of the guide rod 63 are fixed to the connecting part 10 and the support guide rail 20 respectively by threaded connections, and anti-loosening washers can be provided at the threaded connections to prevent loosening. The surface of the guide rod 63 can be polished to reduce frictional resistance when the slider 40 slides. The preload of the compression spring 62 is controlled by adjusting the fixed positions at both ends of the guide rod 63, thereby adapting to the fixing requirements of objects of different sizes.
[0043] By adding a guide rod 63, the extension and retraction of the compression spring 62 is always along a predetermined axis, effectively preventing the slider 40 from jamming due to the spring 62's skewness. The guide rod 63 also serves as the sliding track for the slider 40, forming a dual guiding system with the support guide rail 20, significantly improving the stability of the slider 40's movement. The clearance between the perforation and the guide rod 63 is precisely calculated to ensure smooth sliding while preventing radial wobble. Therefore, the fixing process of the constrained object is more reliable, especially suitable for scenarios requiring frequent position adjustments, such as the rapid positioning and fixing of portable gas stoves in outdoor activities.
[0044] In other embodiments, the slider 40 can also clamp the constrained object by the mutual repulsion of two magnets. Specifically, as... Figure 8 and Figure 9 As shown, a first magnet 65 is provided on the side of the slider 40 adjacent to the connecting part 10, and a second magnet 66 is provided on the side of the connecting part 10 adjacent to the slider 40. The first magnet 65 and the second magnet 66 have opposite polarities. Under the action of magnetic repulsion, the slider 40 clamps the constrained object.
[0045] Furthermore, in some embodiments, the slider 40 is provided with a pulley groove, and a guide pulley that rolls along the support rail 20 is provided in the pulley groove.
[0046] Specifically, the pulley groove is a recessed structure formed inside the slider 40, the shape of which matches the shape of the guide pulley. The guide pulley is rotatably mounted in the pulley groove via bearings or pins, and the outer circumferential surface of the pulley contacts the surface of the support guide rail 20. As a preferred embodiment, the guide pulley can be made of metal or engineering plastic.
[0047] The rolling contact between the guide pulley and the support rail 20 effectively reduces the frictional resistance of the slider 40 during movement. Compared to traditional sliding friction, rolling friction makes the movement of the slider 40 smoother and requires less effort. Simultaneously, the guide pulley prevents the slider 40 from tilting during movement, ensuring that it always moves smoothly along the axial direction of the support rail 20.
[0048] This application also proposes a desktop component, such as... Figure 10 , Figure 11 and Figure 12 As shown, it includes a desktop 30 and a desktop extension module as described in any of the above technical solutions, wherein the desktop extension module is connected to the desktop 30.
[0049] The desktop 30 component of this application, by connecting the desktop expansion module to the desktop 30, enables the fixation of constrained objects, such as the spider furnace 70, or as... Figure 4The high-altitude gas cylinder 71 and stove 72 shown are, or as... Figure 5 The water pump 73 shown needs to be used with a clamp 74 that can support the high-altitude gas tank 71 or the water pump 73. Other items with support legs, such as portable gas stoves or portable gas cooktops, can also be used to secure outdoor audio equipment, portable projectors, small toolboxes, and other items that may slide due to external forces, as long as their bottom structure (such as legs, frames, etc.) is compatible with the constraint mechanism of this application.
[0050] In use, the object to be constrained is placed on the support rail 20, and the sliding slider 40, together with the stop block 50, clamps and fixes the object. The slider 40 and stop block 50 of the desktop extension module work together to adjust the fixing position, accommodating objects of different sizes. The parallel rail design increases support stability, suitable for scenarios requiring horizontal fixation. The constraint provides continuous pressure to prevent the slider 40 from shifting, thus preventing the object from tipping over. Compared to directly placing the object on the desktop 30, this structure provides a more reliable fixing method, solving the problem of unstable equipment placement during outdoor activities.
[0051] Furthermore, in some embodiments, the desktop extension module is fixedly connected to the desktop 30 via a connector.
[0052] Specifically, such as Figure 10 As shown, the connector is a bolt assembly 67, which is fixed by using bolts to pass through and lock the connection through corresponding threaded holes provided on the desktop 30 and the connecting part 10. Furthermore, the installation position of the connector can be set at the edge of the desktop 30 or a preset installation area according to actual needs. The installation area can be prefabricated with a reinforcing structure to improve the connection strength. In other embodiments, such as... Figure 11 As shown, the connector can also be a table clip 68, which is fixedly connected to the connecting part 10 of the desktop extension module and the table clip 68, and then the table clip 68 is fixed to the edge of the desktop 30.
[0053] In other embodiments, the desktop expansion module and the desktop 30 can be fixedly connected by magnetic attraction. Specifically, magnets are fixed at the connection part 10 of the desktop expansion module and the installation area of the desktop 30, respectively. By attracting each other, the pressure between the connection part 10 and the installation area is increased, thereby increasing the frictional resistance when the two move, and preventing the connection part 10 from leaving the installation area.
[0054] The use of connectors ensures a stable installation of the desktop expansion module, solving the problem of devices such as portable gas stoves tipping over due to insecure connections to the desktop 30 during outdoor use. Mechanical fixing effectively resists lateral force interference, and the connector structure is simple and reliable, facilitating quick installation and disassembly. In practice, the selection and installation method of the connectors can be adapted to different desktop 30 materials and load-bearing requirements, offering high practicality and scalability.
[0055] Furthermore, in some of these embodiments, such as Figure 12 As shown, the desktop 30 has a guide groove 31 extending in the horizontal direction, and the connecting part 10 has a guide block adapted to the guide groove 31. The guide groove 31 is used to support the connecting part 10 in the vertical direction and to allow the guide block to slide in the horizontal direction.
[0056] The guide groove 31 can adopt a T-groove or dovetail groove structure to effectively prevent the guide block from dislodging. The guide block can be made of nylon, aluminum alloy, or engineering plastic, with nylon having self-lubricating properties. The clearance between the guide groove 31 and the guide block is controlled within the range of 0.1-0.5mm to ensure smooth sliding while avoiding excessive wobble. Furthermore, the friction between the guide block and the guide groove 31 can be further reduced by embedding ball bearings in the guide block. A dust cover can be installed on the guide groove 31 to prevent foreign objects from entering and affecting sliding.
[0057] The guide groove 31 and guide block work together to achieve flexible horizontal adjustment and stable vertical support for the desktop extension module. The guide groove 31 bears all the vertical load of the connecting part 10, avoiding the drawbacks of traditional bolt connections that require repeated adjustments and tightening. The sliding resistance of the guide block within the groove can be optimized through material selection and clearance control, ensuring both positioning stability and ease of manual operation. Compared to direct fixing, this structure allows users to quickly adjust the position of the extension components according to actual needs, making it particularly suitable for outdoor activities where frequent layout changes are required.
[0058] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
