Description

Technical Field

[0001] This application relates to the field of bed technology, specifically to a cot. Background Technology

[0002] Camp beds, as a type of portable folding bed, are widely used in outdoor camping, temporary accommodation, and other scenarios.

[0003] Existing cots typically use pins or buckles for unfolding and folding. When unfolding the cot, the user needs to precisely align the pin with the pin hole or press the buckle firmly into the locking position, which is not very convenient. In addition, more seriously, if the pin is not fully inserted into the pin hole or the buckle is in a loose state, the cot may suddenly fold during use, posing a great safety hazard.

[0004] Therefore, there is room for further improvement in the existing cot technology. Utility Model Content

[0005] In view of this, and in response to the technical problems of the existing cots, such as inconvenient unfolding and folding operations and unreliable locking that may lead to accidental folding, this application provides a cot that is easy to operate and has reliable locking, significantly improving the safety of the cot.

[0006] This application provides a camp bed, comprising: bed surface; A guide lock seat is connected to the bed surface, and a guide groove is provided on the guide lock seat; A support rod has a sliding part at one end, and the sliding part is slidably engaged with the guide groove. A support leg is located below the bed surface, and the support leg is rotatably connected to the end of the support rod away from the sliding part; A limiting groove is provided at the end of the guide groove away from the bed surface. When the sliding part slides into the limiting groove, the position of the support rod is locked.

[0007] Compared with existing technologies, the cot of this application allows the user to easily unfold the cot by simply pressing the bed surface sleeve and bed surface rod or pressing the connecting piece. This causes the sliding part of the support rod to slide along the guide groove and eventually fall into the limiting groove. This process is very convenient and replaces the cumbersome operation of traditional pins that require precise alignment or latches that require forceful pressing. At the same time, when the sliding part slides into the limiting groove, the vertical load borne by the cot during use will directly act on the groove wall. Since the direction of this force is perpendicular to or at a large angle to the direction in which the sliding part needs to move out of the limiting groove, external force cannot directly drive the sliding part to move in the opposite direction and disengage. This forms a stable mechanical self-locking system. This locking method does not depend on the operator's force and fundamentally eliminates the hidden danger of traditional locks accidentally disengaging due to loose locking or incomplete locking under vibration, ensuring absolute stability in the unfolded state.

[0008] Preferred options also include: The operating handle is hinged to the guide lock seat; The operating part is located at the end of the operating handle away from the support rod; A lifting part is provided at one end of the operating handle near the support rod, and is used to abut against and lift the support rod.

[0009] The operating part is provided with an elastic element at one end near the guide lock seat. One end of the elastic element acts on the guide lock seat, and the other end acts on the operating part. The elastic element is used to apply force when the operating part is working.

[0010] In this embodiment, an operating handle is added to the guide lock seat. When the user presses the operating part, the lifting part can easily abut against and lift the support rod, which can quickly unlock and complete the folding, greatly simplifying the operation steps and saving time and effort. At the same time, the elastic element on the operating part ensures that the operating handle always maintains a certain elasticity, so that the operating handle can not only quickly return to its original position during the movement, but also limit the operating handle to stay in the optimal position during the movement.

[0011] Preferred options also include: A hinged seat, one end of which is connected to the guide lock seat, and the other end of which is connected to the support leg; The hinge seat is provided with a receiving cavity, and the end of the support rod away from the sliding part is located in the receiving cavity and is rotatably connected to the hinge seat through the hinge shaft.

[0012] In this embodiment, a new hinge seat is added and a receiving cavity is provided on the hinge seat. The rotating connection end of the support rod can be accommodated in the receiving cavity and a stable connection is achieved through the hinge shaft, so that the movement trajectory of the support rod during the folding and unfolding process is more stable and reliable.

[0013] Preferably, a return spring is provided inside the receiving cavity, and hooks are provided at both ends of the return spring, with the two hooks respectively connecting the support rod and the inner wall of the receiving cavity; The reset spring is used to drive the support rod toward the limiting groove.

[0014] In this embodiment, the return spring ensures that the cot remains stably locked in the unfolded state, preventing accidental loosening. It also helps the support rod to return to its original position after folding, preparing for the next unfolding, greatly improving safety and ease of operation.

[0015] Preferably, the operating part is an arc-shaped arm, and the outer surface of the arc-shaped arm is provided with a plurality of anti-slip protrusions. The plurality of anti-slip protrusions are spaced apart along the length direction of the arc-shaped arm, and the anti-slip protrusions are used to increase the friction when gripping.

[0016] In this embodiment, the operating part is set as an arc-shaped arm, which can increase the user's grip comfort. The anti-slip ridges can increase the friction when the user grips it, thereby effectively avoiding slippage during operation and further improving the safety of the product.

[0017] Preferably, the lifting part is a cylindrical strip that extends along the width direction of the operating handle, and the two ends of the cylindrical strip are respectively hinged to the two side arms at the end of the operating handle.

[0018] In this embodiment, the lifting part is set as a cylindrical strip structure, which can reduce frictional loss with the support rod, thereby increasing the smoothness of operation.

[0019] Preferred options also include: A connector is provided between the folding locking mechanism and the bed surface; One end of the connector is provided with a U-shaped groove, and the other end is provided with a sleeve post; The guide lock seat is also provided with a connecting post; The bed surface is provided with bed surface rod sleeves on both sides along its length, and a bed surface rod is inserted through the bed surface rod sleeve. The U-shaped groove is engaged with the bed surface rod, and the sleeve post is sleeved on the connecting post.

[0020] In this embodiment, a connecting component is further added, with a U-shaped groove at one end engaging with the bed surface rod, and a sleeve post at the other end engaging with the guide lock seat connecting post, thereby enhancing the quick assembly and disassembly and stable connection between the guide lock seat and the bed surface.

[0021] Preferably, the guide lock seat is provided with a gripping part, which is used to provide a gripping force point when the bed surface is unfolded.

[0022] In this embodiment, a gripping part is provided outside the guide lock seat, providing the user with a stable point of force during operation, making operation more convenient.

[0023] Preferably, the gripping part is a recessed structure formed on the guide lock seat, and the recessed structure is symmetrically arranged on both sides of the guide lock seat.

[0024] Preferably, the support leg includes: At least two sets of X-shaped support leg units, each set of X-shaped support leg units being spaced apart along the length of the bed surface; Each X-shaped support leg unit includes two X-shaped support legs, and a crossbar connects the two X-shaped support legs. The hinge base is provided with a connection hole, and the top end of the X-shaped support leg is inserted into the connection hole of the hinge base.

[0025] In this embodiment, the X-shaped legs and crossbars effectively enhance the overall structural strength and stability of the support legs. Attached Figure Description

[0028] To enable those skilled in the art to better understand the technical solutions of this disclosure, the following detailed, clear, and complete description of this disclosure is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this disclosure and are not intended to limit it.

[0029] In the description of this application, the use of "first" and "second" is for the purpose of distinguishing technical features only, and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated or the order of the technical features indicated.

[0030] Those skilled in the art should understand that in the disclosure of this application, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this application.

[0031] The present application will now be described in further detail with reference to the accompanying drawings, see below. Figures 1 to 6 illustrate.

[0032] This application provides a camp bed, such as Figures 1 to 5 As shown, it includes a bed surface 1, a guide lock seat 2, a support rod 3, and a support leg 4. The support leg 4 is located below the bed surface 1 to support the bed surface 1. The guide lock seat 2 is connected to the bed surface 1 and has a guide groove 21. One end of the support rod 3 has a sliding part 31, which slides in cooperation with the guide groove 21. The end of the support rod 3 away from the sliding part 31 is rotatably connected to the support leg 4. The guide groove 21 extends along the length of the bed surface 1, and the end of the guide groove 21 away from the bed surface 1 has a limiting groove 22.

[0033] The cot of this application achieves switching and locking between the unfolded and folded states by sliding the sliding part 31 in the guide groove 21 and engaging it with the limiting groove 22. When the sliding part 31 slides along the guide groove 21 and falls into the limiting groove 22, the position of the support rod 3 is locked, and the cot remains in a stable unfolded state. When an external force is applied to make the sliding part 31 disengage from the limiting groove 22 and slide back along the guide groove 21, the support leg 4 can be retracted, and the cot can be folded.

[0034] Furthermore, such as Figure 3 , Figure 4 As shown, the cot also includes an operating handle 5. The operating handle 5 is hinged to the guide lock seat 2. The operating handle 5 includes an operating part 51, a lifting part 52, and an elastic element 53. The operating part 51 is located at the end of the operating handle 5 away from the support rod 3, for user operation; the lifting part 52 is located at the end of the operating handle 5 near the support rod 3. When the user presses down on the operating part 51, the lifting part 52 lifts the support rod 3 upward, making it easier for the sliding part 31 to disengage from the limiting groove 22, thereby simplifying the folding operation and saving time and effort. At the same time, an elastic element 53 is provided between the operating part 51 and the guide lock seat 2. One end of the elastic element 53 acts on the operating part 51, and the other end acts on the guide lock seat 2, providing a return force for the operating handle 5, so that the operating handle 5 always maintains a certain elasticity, allowing the operating handle 5 to not only quickly return to its original position during movement, but also to limit the operating handle 5 to remain in the optimal position during movement.

[0035] At the same time, such as Figure 3 , Figure 4 As shown, the cot also includes a hinge seat 6. One end of the hinge seat 6 is connected to the guide lock seat 2, and the other end is connected to the support leg 4. The hinge seat 6 has a receiving cavity 61, and the end of the support rod 3 away from the sliding part 31 is located in the receiving cavity 61, and is rotatably connected to the hinge seat 6 through the hinge shaft 32. This structure makes the rotation trajectory of the support rod 3 more stable and reliable.

[0036] In an optional embodiment of this application, such as Figure 3 , Figure 4 As shown, a return spring 62 is provided inside the receiving cavity 61. Hooks 621 are provided at both ends of the return spring 62, and the two hooks 621 are respectively connected to the support rod 3 and the inner wall of the receiving cavity 61. The return spring 62 provides elastic force, driving the support rod 3 to tend to move towards the limiting groove 22, thereby enhancing the self-locking stability of the cot in the unfolded state, and assisting the support rod 3 in returning to its original position after folding.

[0037] Based on any of the above embodiments, the operating handle 5 will be further described. For example... Figure 3 , Figure 4 As shown, the operating part 51 is an arc-shaped arm with multiple anti-slip protrusions 511 on its outer surface. These protrusions are spaced apart along the length of the arc-shaped arm to significantly increase friction when the user grips it, preventing slippage during operation. The lifting part 52 is a cylindrical strip that extends along the width of the operating handle 5, with both ends hinged to the two arms at the ends of the operating handle 5. The cylindrical strip structure effectively reduces frictional wear with the support rod 3, making operation smoother.

[0038] Based on any of the above embodiments, the connection structure is further described. For example... Figure 1, Figure 2 , Figure 6 As shown, the cot also includes a connector 7. The connector 7 is located between the guide lock seat 2 and the bed surface 1. One end of the connector 7 has a U-shaped groove 71, and the other end has a connecting post 72. The guide lock seat 2 has a connecting post 23. Bed surface rod sleeves 11 are provided on both sides along the length of the bed surface 1, and bed surface rods 12 pass through the bed surface rod sleeves 11. During assembly, the U-shaped groove 71 engages with the bed surface rod 12, and the connecting post 72 is sleeved and fixed to the connecting post 23. This connection method enables quick assembly and disassembly and a stable connection between the guide lock seat 2 and the bed surface 1.

[0039] In this application, the guide lock seat 2 is provided with a gripping part 24 to provide a stable gripping point for the user when the bed surface 1 is unfolded. Specifically, the gripping part 24 is a recessed structure formed on the guide lock seat 2 and is symmetrically arranged on both sides of the guide lock seat 2.

[0040] Furthermore, the supporting leg 4 will be described in more detail. For example... Figure 1 , Figure 2 As shown, the support leg 4 includes at least two sets of X-shaped support leg units, each set of X-shaped support leg units being spaced apart along the length of the bed surface 1. Each set of X-shaped support leg units includes two X-shaped support legs 41, with a crossbar 42 connecting the two X-shaped support legs 41, effectively enhancing the overall structural strength and stability of the support leg 4. The hinge seat 6 is provided with a connection hole 63, and the top end of the X-shaped support leg 41 is inserted into the connection hole 63, achieving a reliable connection between the support leg 4 and the hinge seat 6.

[0041] It should be noted that the various embodiments of this application can be arbitrarily combined into new embodiments, provided that the solutions do not conflict and the technical solutions can coexist.

[0042] The present application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present application. The descriptions of the embodiments above are only for the purpose of helping to understand the present application and its core ideas. It should be noted that those skilled in the art can make several improvements and modifications to the present application without departing from the principles of the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.
