[0002] This application claims priority to Chinese Patent Application No. 202510069674.5, filed on January 16, 2025, entitled “Support Frame and Tent”, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of mechanical structure technology, and more specifically, to a support frame and a tent. Background Technology

[0004] Support frames, as an important load-bearing structure, are widely used in various scenarios, such as tent support, billboard fixing, and stage equipment support. In emergency rescue and field medical fields, support frames play a crucial supporting role in tent structures, determining the tent's setup efficiency, stability, and wind resistance. However, related support frames still face many technical bottlenecks in practical applications, especially in terms of insufficient performance in complex environments.

[0005] Most current frame tents employ foldable support frame structures to improve portability and ease of use. Taking the tent frame disclosed in patent number CN202211130595.3 as an example, this type of support frame used to support the tent fabric to form the tent is typically based on a scissor-joint assembly design, connecting two gantry frames via the scissor-joint assembly. The first connecting end of the scissor-joint assembly is hinged to the gantry, while the second connecting end is slidably connected to the gantry. During folding and unfolding, the second connecting end of the scissor-joint assembly slides on the gantry, causing a change in the distance between the hinge point and the sliding point on the same gantry. Specifically, during unfolding, as the distance between the gantry frames increases, the distance between the first and second connecting ends on the gantry gradually decreases, resulting in a reduced supporting range of the scissor-joint assembly on the gantry, thus reducing the overall stability of the support frame. Furthermore, due to distance limitations, the tent frame spacing is restricted, requiring an increase in the number of gantry frames to achieve the same tent frame length. In addition, the unfolded scissor-joint assembly is prone to deformation under external forces, especially in strong winds or heavy-load environments, making it difficult to provide sufficient support.

[0006] The shortcomings of the existing support frames in terms of structural stability and wind resistance affect the safety of tents in complex environments. Meanwhile, traditional unlocking mechanisms are cumbersome, time-consuming, and labor-intensive to set up and dismantle tents, requiring a high level of user skill and failing to meet the rapid deployment needs of emergency rescue scenarios. Although some technologies have improved this through lightweight materials and modular design, the problems of poor tent stability and operational complexity remain unresolved.

[0007] Therefore, there is an urgent need to develop a new type of frame support structure. By optimizing the design of connecting components and folding mechanisms, the stability, portability, and ease of operation of the tent support system can be improved, thereby meeting the actual needs of rapid deployment and reliable load-bearing in special scenarios such as emergency rescue and field medical care. Summary of the Invention

[0008] The purpose of this application is to provide a support frame and tent, which connects a first gantry and a second gantry via a folding assembly. Based on the extendability of the first and second telescopic rods in the folding assembly, the stability of the support frame can be significantly improved. Furthermore, when the support frame is configured as a tent frame, the span of the tent frame can be increased; that is, with a fixed tent frame length, fewer gantry frames are required, optimizing the design and reducing manufacturing costs. Simultaneously, the overall weight is reduced and the space occupied is minimized, making it suitable for scenarios requiring high portability, such as mobile hospitals. In addition, by improving the uniformity of the cross-distribution of the folding assembly, the uniformity of tent fabric support is further improved, enhancing the overall snow load resistance of the tent. Moreover, since the support frame does not require locking or unlocking, the operation steps are simplified, and the convenience of storage and deployment is improved. This application achieves a comprehensive improvement in the stability, convenience, and economy of the support frame, and has the advantage of high reliability.

[0009] In a first aspect, this application provides a support frame, including a first gantry, a second gantry, and a folding assembly; the first gantry includes at least two first support rods, and the second gantry includes at least two second support rods; the folding assembly includes a first telescopic rod and a second telescopic rod; the first telescopic rod and the second telescopic rod intersect and are coplanar with the first support rod; the plane in which the first telescopic rod, the second telescopic rod, and the first support rod are located is a support surface; a first connecting end of the first support rod is rotatably connected to one end of the first telescopic rod, and a second connecting end of the first support rod is rotatably connected to one end of the second telescopic rod; a third connecting end of the second support rod located on the support surface is rotatably connected to the other end of the first telescopic rod, and a fourth connecting end of the second support rod located on the support surface is rotatably connected to the other end of the second telescopic rod.

[0010] In the aforementioned support frame, because both the first and second telescopic rods in the folding assembly are extendable, during the support frame's folding process (i.e., the process of the first and second gantry frames moving closer together), the first and second telescopic rods only need to shorten their respective lengths, without any connecting end on the folding assembly sliding on the first or second support rod. This prevents changes to the distance between the two connection points between the folding assembly and the first or second support rod. Consequently, the situation where the support frame's support range decreases as the unfolded portion of the frame expands, leading to decreased stability, is avoided, thus improving the stability of the support frame.

[0011] In conjunction with the first aspect, optionally, the first telescopic rod and the second telescopic rod are rotatably connected; wherein the rotatable connection is located at the intersection of the first telescopic rod and the second telescopic rod.

[0012] The aforementioned support frame, by rotating the first and second telescopic rods together at their intersection, creates two fixed triangles formed by the first telescopic rod, the first support rod, and the second support rod, while maintaining the same length of both. Due to the stability of triangles, no relative movement will occur between any two of the first telescopic rod, the first support rod, and the second support rod. This further improves the stability of the support frame. Furthermore, during the deployment of the support frame (the process of the first and second masts moving away from each other), the relative movement between the first and second masts is constrained to linear movement.

[0013] In conjunction with the first aspect, optionally, the first telescopic rod includes a first head section rod, a first middle section rod, and a first tail section rod; one end of the first middle section rod is telescopically connected to the first head section rod, and the other end of the first middle section rod is telescopically connected to the first tail section rod; the second telescopic rod includes a second head section rod, a second middle section rod, and a second tail section rod; one end of the second middle section rod is telescopically connected to the second head section rod, and the other end of the second middle section rod is telescopically connected to the second tail section rod; the first middle section rod and the second middle section rod are rotatably connected.

[0014] The aforementioned support frame, through the telescopic connection between multiple segments to form the first and second telescopic rods, not only achieves the telescopic nature of the first and second telescopic rods but also simplifies their structure.

[0015] In conjunction with the first aspect, optionally, the first telescopic rod further includes a first limiting mechanism and a second limiting mechanism; the first limiting mechanism is configured to restrict the telescopic movement between the first middle section rod and the first first section rod when the first middle section rod and the first first section rod are extended to their longest states; the second limiting mechanism is configured to restrict the telescopic movement between the first middle section rod and the first last section rod when the first middle section rod and the first last section rod are extended to their longest states; the second telescopic rod further includes a third limiting mechanism and a fourth limiting mechanism; the third limiting mechanism is configured to restrict the telescopic movement between the second middle section rod and the second first section rod when the second middle section rod and the second first section rod are extended to their longest states; the fourth limiting mechanism is configured to restrict the telescopic movement between the second middle section rod and the second last section rod when the second middle section rod and the second last section rod are extended to their longest states.

[0016] The aforementioned support frame, by configuring a first limiting mechanism and a second limiting mechanism on the first telescopic rod, and a third limiting mechanism and a fourth limiting mechanism on the second telescopic rod, achieves locking of the first and second telescopic rods in their longest states, thereby further improving the stability of the support frame in the deployed state.

[0017] In conjunction with the first aspect, optionally, the first connecting end and the second connecting end are located at the two ends of the first support rod; the third connecting end and the fourth connecting end are located at the two ends of the second support rod.

[0018] The aforementioned support frame maximizes the supporting range of the folding component on the gantry by defining the first and second connecting ends as the two ends of the first support rod, and the third and fourth connecting ends as the two ends of the second support rod. This, in turn, maximizes the stability of the support frame in the unfolded state.

[0019] In conjunction with the first aspect, optionally, the first telescopic rod and the second telescopic rod each have a retracted state when retracted to their shortest length; in the retracted state, the length of the first telescopic rod does not exceed the distance between the first connecting end and the second connecting end; in the retracted state, the length of the first telescopic rod does not exceed the distance between the third connecting end and the fourth connecting end; in the retracted state, the length of the second telescopic rod does not exceed the distance between the first connecting end and the second connecting end; in the retracted state, the length of the second telescopic rod does not exceed the distance between the third connecting end and the fourth connecting end.

[0020] The aforementioned support frame, by limiting the distance relationships between the first and second telescopic rods and the first and second connecting ends, as well as the distance relationships between the first and second telescopic rods and the third and fourth connecting ends in the retracted state, allows the first and second gantry frames to be brought as close as possible, thereby enabling the support frame to be folded to the maximum extent.

[0021] In conjunction with the first aspect, optionally, at least one of the first connecting end and the fourth connecting end is provided with a first connecting portion; the first connecting portion extends along the support surface and is located between the first support rod and the second support rod; at least one of the second connecting end and the third connecting end is provided with a second connecting portion; the second connecting portion extends along the support surface and is located between the first support rod and the second support rod.

[0022] The aforementioned support frame, by providing a first connecting part and a second connecting part on the first telescopic rod and / or the second telescopic rod respectively, when the first gantry and the second gantry are maximally close to the ground, the first connecting part and the second connecting part are located between the first support rod and the second support rod, thereby limiting the zero-distance contact between the first support rod and the second support rod. That is, even when the support frame is in the folded state, there is still a gap between the first support rod and the second support rod, thus preventing the operator from having their hand pinched by the first support rod and the second support rod during the operation of folding the support frame.

[0023] In conjunction with the first aspect, optionally, a connecting rod is also included; one end of the connecting rod is detachably connected to the first gantry, and the other end of the connecting rod is detachably connected to the second gantry.

[0024] The aforementioned support frame, by providing a detachable connecting rod between the first gantry and the second gantry, further ensures the stability of the distance maintained between the first gantry and the second gantry in the unfolded state, thereby further improving the stability of the support frame in the unfolded state.

[0025] In conjunction with the first aspect, optionally, the first gantry further includes a first rotary connection mechanism; the two connecting ends of the first rotary connection mechanism are respectively connected to the ends of the two first support rods, and are configured to realize folding and unfolding between at least two first support rods; the second gantry further includes a second rotary connection mechanism; the two connecting ends of the second rotary connection mechanism are respectively connected to the ends of the two second support rods, and are configured to realize folding and unfolding between at least two second support rods.

[0026] The aforementioned support frame achieves folding and unfolding between the two first support rods on the first gantry through a first rotary connection mechanism, and folding and unfolding between the two second support rods on the second gantry through a second rotary connection mechanism, thus realizing the foldability of the first and second gantry themselves. This allows the support frame to be folded not only by using the folding assembly to bring the first and second gantry closer together, but also by utilizing the foldability of the first and second gantry themselves, further reducing the space occupied by the support frame in the folded state.

[0027] Secondly, this application provides a tent, including a tent fabric and a support frame as described.

[0028] The aforementioned tent has the same beneficial effects as the first aspect, which will not be elaborated here.

[0029] In summary, the support frame and tent provided in this application connect the first and second gantry frames respectively through intersecting folding components. Since both the first and second telescopic rods in the folding components are telescopic, as the first and second gantry frames approach each other, the first and second telescopic rods only need to shorten their own lengths accordingly, without any connection end on the folding component sliding on the first or second support rod. This prevents changes in the distance between the two connection points between the folding component and the first or second support rod. Consequently, the stability of the support frame is improved, as the support frame expands further and the supporting range of the folding component on the gantry decreases. By rotating the first and second telescopic rods at their intersection, while keeping their lengths constant, the first telescopic rod, the first support rod, and the second support rod form two fixed triangles. This prevents relative movement between any two of the first telescopic rod, the first support rod, and the second support rod, further enhancing the stability of the support frame. By defining the first and second connecting ends as the two ends of the first support rod, and the third and fourth connecting ends as the two ends of the second support rod, the supporting range of the folding component on the gantry is maximized, thereby maximizing the stability of the support frame in the unfolded state. By providing the first and second connecting parts on the first and / or second telescopic rods respectively, the operator's hands are prevented from being pinched by the first and second support rods during the folding process of the support frame.

Detailed Implementation

[0040] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0041] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0042] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0043] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of the invention is in use. They are used 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, they should not be construed as limitations on this application. In addition, the terms "first," "second," and "third," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0044] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0046] Please refer to Figure 1, which is a first perspective view of the support frame 100 provided in this embodiment. The support frame 100 provided in this embodiment may include a first gantry 110, a second gantry 120, and a folding assembly 130. The first gantry 110 may include at least two first support rods 111, and the second gantry 120 may include at least two second support rods 121. The folding assembly 130 may include a first telescopic rod 131 and a second telescopic rod 132. The first telescopic rod 131 and the second telescopic rod 132 may be arranged intersectingly, and the structure in which the first telescopic rod 131 and the second telescopic rod 132 are intersecting may be coplanar with the first support rod 111. The plane in which the first telescopic rod 131, the second telescopic rod 132, and the first support rod 111 are located may be a support surface. The first connecting end 1111 of the first support rod 111 may be rotatably connected to one end of the first telescopic rod 131, and the second connecting end 1112 of the first support rod 111 may be rotatably connected to one end of the second telescopic rod 132. The third connecting end 1211 of the second support rod 121 located on the support surface can be rotatably connected to the other end of the first telescopic rod 131, and the fourth connecting end 1212 of the second support rod 121 located on the support surface can be rotatably connected to the other end of the second telescopic rod 132.

[0047] The first gantry 110 and the second gantry 120 can be frames similar in shape to door frames. The first gantry 110 and the second gantry 120 are spaced apart and connected by a scissor assembly or a folding assembly 130 as described in the embodiments of this application. The first gantry 110, the second gantry 120, and the folding assembly 130 or the scissor assembly form a support frame 100 or a part of a support frame 100. The support frame 100 or a part of the support frame 100 can be configured to support items such as tent fabric, billboards, or stage lighting.

[0048] It should be understood that the support frame 100 provided in this application embodiment may also include a third gantry, a fourth gantry, and a fifth gantry, etc. Those skilled in the art can determine the number of gantry according to actual needs. Furthermore, the first gantry 110 and the second gantry 120 can be connected by a folding assembly 130 or by multiple folding assemblies 130.

[0049] The first telescopic rod 131 can be a rod formed by at least two rods or pipes sleeved together. Similarly, the second telescopic rod 132 can also be a rod formed by at least two rods or pipes sleeved together.

[0050] Since the first telescopic rod 131, the second telescopic rod 132, and the first support rod 111 are coplanar, the axis of rotation connecting any two of these rods is typically perpendicular to the support surface. Correspondingly, the second support rod 121 is also located on the support surface and is connected to both the first telescopic rod 131 and the second telescopic rod 132. The axis of rotation connecting any two of these rods is also perpendicular to the support surface. To ensure that the first telescopic rod 131, the second telescopic rod 132, the first support rod 111, and the second support rod 121 are coplanar, the rotational connections among them can be hinged to restrict the axis of rotation from being perpendicular to the support surface. A rotating pin can also be inserted at the intersection of the first telescopic rod 131 and the second telescopic rod 132 to ensure that the first telescopic rod 131, the second telescopic rod 132, the first support rod 111, and the second support rod 121 are coplanar. The length direction of the inserted rotating pin is perpendicular to the support surface.

[0051] In the aforementioned folding assembly 130, both the first telescopic rod 131 and the second telescopic rod 132 that intersect can extend and retract. Therefore, during the process of folding the support frame 100 (that is, the process of the first gantry 110 and the second gantry 120 approaching each other), the first telescopic rod 131 and the second telescopic rod 132 only need to shorten their own lengths accordingly, without any connecting end on the folding assembly 130 sliding on the first support rod 111 or the second support rod 121. The connection position between the folding assembly 130 and the first support rod 111 and the second support rod 121 will not change. Consequently, the situation where the support frame 100's support effect on the gantry decreases as the degree of unfolding increases will not occur, thereby improving the stability of the support frame 100 after unfolding.

[0052] Please refer to Figure 2, which is a partial perspective view of the connection between the gantry and the folding assembly 130 in the support frame 100 provided in this embodiment. In some optional embodiments, the first telescopic rod 131 can be rotatably connected to the second telescopic rod 132. The rotatable connection between the first telescopic rod 131 and the second telescopic rod 132 can be located at the intersection of the first telescopic rod 131 and the second telescopic rod 132.

[0053] Similarly, the rotatable connection at the intersection of the first telescopic rod 131 and the second telescopic rod 132 can be achieved by inserting a rotating pin at the intersection. Of course, those skilled in the art can also adopt other methods from the relevant technologies in the field according to actual application needs. For example, a rotating pin can be fixedly provided on the first telescopic rod 131, protruding towards the second telescopic rod 132. A pin hole is provided on the second telescopic rod 132, the position, size, and shape of which are adapted to the protruding rotating pin on the first telescopic rod 131. The protruding rotating pin is accommodated in the pin hole and can rotate, thereby allowing the first telescopic rod 131 and the second telescopic rod 132 to be rotatably engaged.

[0054] The first telescopic rod 131 and the second telescopic rod 132 are rotatably connected at their intersection. With the lengths of both the first telescopic rod 131 and the second telescopic rod 132 remaining constant, the first telescopic rod 131, the second telescopic rod 132, the first support rod 111, and the second support rod 121 form two fixed triangles. Due to the stability of triangles, no relative movement will occur between any two of the first telescopic rod 131, the second telescopic rod 132, the first support rod 111, and the second support rod 121. This further improves the stability of the support frame 100 and also ensures that during the deployment of the support frame 100 (the process of the first gantry 110 and the second gantry 120 moving away from each other), the relative movement between the first gantry 110 and the second gantry 120 is constrained to linear movement.

[0055] Referring to Figure 2, in some optional embodiments, the first telescopic rod 131 may include a first head rod 1311, a first middle rod 1312, and a first tail rod 1313. One end of the first middle rod 1312 may be telescopically connected to the first head rod 1311, and the other end of the first middle rod 1312 may be telescopically connected to the first tail rod 1313. The second telescopic rod 132 may include a second head rod 1321, a second middle rod 1322, and a second tail rod 1323. One end of the second middle rod 1322 may be telescopically connected to the second head rod 1321, and the other end of the second middle rod 1322 may be telescopically connected to the second tail rod 1323. The first middle rod 1312 may be rotatably connected to the second middle rod 1322.

[0056] The first initial rod 1311 and the first final rod 1313 can be inner sleeve rods, the first middle rod 1312 can be an outer sleeve rod, and the first telescopic rod 131 can be structured such that both ends of the first middle rod 1312 are respectively sleeved outside the first initial rod 1311 and the first final rod 1313. Conversely, the first initial rod 1311 and the first final rod 1313 can be outer sleeve rods, the first middle rod 1312 can be an inner sleeve rod, and the first telescopic rod 131 can be structured such that both ends of the first middle rod 1312 are respectively sleeved inside the first initial rod 1311 and the first final rod 1313. Furthermore, the structure of the first telescopic rod 131 can also be such that the first head section rod 1311 is sleeved on one end of the first middle section rod 1312, and the other end of the first middle section rod 1312 is sleeved on the first tail section rod 1313; or, the first tail section rod 1313 is sleeved on one end of the first middle section rod 1312, and the other end of the first middle section rod 1312 is sleeved on the first head section rod 1311.

[0057] The first middle section 1312 can be a fixed-length rod, or it can be a telescopic rod formed by connecting multiple sections of rod through a connection relationship similar to that described above. That is, when the first middle section 1312 is a fixed-length rod, the first telescopic rod 131 is usually composed of three sections of rod. When the first middle section 1312 is a telescopic rod formed by connecting multiple sections of rod through a connection relationship similar to that described above, the first telescopic rod 131 is usually composed of four or more sections of rod.

[0058] The structure of the second telescopic rod 132 can be similar to that of the first telescopic rod 131 described above. Further details will not be provided here.

[0059] The aforementioned first telescopic rod 131 and second telescopic rod 132 are formed by a multi-segment telescopic connection, which not only allows for free extension and retraction but also simplifies the structure of the first telescopic rod 131 and the second telescopic rod 132. Referring to Figure 2, in some optional embodiments, the first telescopic rod 131 may further include a first limiting mechanism 1314 and a second limiting mechanism 1315. The first limiting mechanism 1314 may be configured to restrict the extension and retraction between the first middle segment rod 1312 and the first first segment rod 1311 when they are extended to their longest state. The second limiting mechanism 1315 may be configured to restrict the extension and retraction between the first middle segment rod 1312 and the first last segment rod 1313 when they are extended to their longest state.

[0060] The second telescopic rod 132 may further include a third limiting mechanism 1324 and a fourth limiting mechanism 1325. The third limiting mechanism 1324 may be configured to restrict the telescopic movement between the second middle section rod 1322 and the second first section rod 1321 when the second middle section rod 1322 and the second first section rod 1321 are extended to their longest positions. The fourth limiting mechanism 1325 may be configured to restrict the telescopic movement between the second middle section rod 1322 and the second last section rod 1323 when the second middle section rod 1322 and the second last section rod 1323 are extended to their longest positions.

[0061] The first limiting mechanism 1314, the second limiting mechanism 1315, the third limiting mechanism 1324, and the fourth limiting mechanism 1325 can all be mechanisms known to those skilled in the art for locking the length of a telescopic rod. For example, annular protrusions are provided at corresponding positions of the first telescopic rod 131 and the second telescopic rod 132 as limits.

[0062] By configuring a first limiting mechanism 1314 and a second limiting mechanism 1315 on the first telescopic rod 131, the first telescopic rod 131 is locked in its longest state. By configuring a third limiting mechanism 1324 and a fourth limiting mechanism 1325 on the second telescopic rod 132, the second telescopic rod 132 is locked in its longest state, further improving the stability of the support frame 100 in the unfolded state.

[0063] Referring to Figures 1 and 2, in some optional embodiments, the first connecting end 1111 and the second connecting end 1112 can be located at both ends of the first support rod 111, respectively. The third connecting end 1211 and the fourth connecting end 1212 can be located at both ends of the second support rod 121, respectively. By defining the first connecting end 1111 and the second connecting end 1112 as the two ends of the first support rod 111, and by defining the third connecting end 1211 and the fourth connecting end 1212 as the two ends of the second support rod 121, the supporting range of the folding assembly 130 on the gantry is maximized, thereby maximizing the stability of the support frame 100 in the unfolded state.

[0064] Referring to Figure 2, in some optional embodiments, the first telescopic rod 131 and the second telescopic rod 132 may each have a retracted state when retracted to their shortest length. In the retracted state, the length of the first telescopic rod 131 does not exceed the distance between the first connecting end 1111 and the second connecting end 1112. In the retracted state, the length of the first telescopic rod 131 does not exceed the distance between the third connecting end 1211 and the fourth connecting end 1212. In the retracted state, the length of the second telescopic rod 132 does not exceed the distance between the first connecting end 1111 and the second connecting end 1112. In the retracted state, the length of the second telescopic rod 132 does not exceed the distance between the third connecting end 1211 and the fourth connecting end 1212.

[0065] With both the first telescopic rod 131 and the second telescopic rod 132 in the retracted state, the support frame 100 is in a folded state. In the folded state, the first mast 110 and the second mast 120 are closest to each other. If the length of the first telescopic rod 131 in the retracted state exceeds the distance between the first connecting end 1111 and the second connecting end 1112, or if the length of the second telescopic rod 132 in the retracted state exceeds the distance between the first connecting end 1111 and the second connecting end 1112, then the first mast 110 and the second mast 120 cannot be brought as close as possible, meaning the support frame 100 cannot be folded to its maximum extent.

[0066] By limiting the distance relationships between the first telescopic rod 131 and the second telescopic rod 132 in the retracted state and the first connecting end 1111 and the second connecting end 1112, as well as the distance relationships between the third connecting end 1211 and the fourth connecting end 1212, the first gantry 110 and the second gantry 120 can be brought as close as possible, thereby enabling the support frame 100 to be folded to the maximum extent.

[0067] Please refer to Figures 3 to 6. Figure 3 is a partial enlarged view of point A in Figure 1; Figure 4 is a partial enlarged view of point B in Figure 1; Figure 5 is a partial enlarged view of point C in Figure 1; and Figure 6 is a partial enlarged view of point D in Figure 1. In some optional embodiments, at least one of the first connecting end 1111 and the fourth connecting end 1212 may be provided with a first connecting portion 1113. The first connecting portion 1113 extends along the support surface and may be located between the first support rod 111 and the second support rod 121. At least one of the second connecting end 1112 and the third connecting end 1211 may be provided with a second connecting portion 1213. The second connecting portion 1213 may extend along the support surface and may be located between the first support rod 111 and the second support rod 121.

[0068] In other words, the first connecting part 1113 may be a protrusion on the first telescopic rod 131 or the second telescopic rod 132, and / or the second connecting part 1213 may be a protrusion on the first telescopic rod 131 or the second telescopic rod 132.

[0069] By providing a first connecting part 1113 and a second connecting part 1213 on the first telescopic rod 131 and / or the second telescopic rod 132 respectively, when the first mast 110 and the second mast 120 are brought as close as possible, the first connecting part 1113 and the second connecting part 1213 are located between the first support rod 111 and the second support rod 121, thereby limiting the zero-distance contact between the first support rod 111 and the second support rod 121. That is, even when the support frame 100 is in the folded state, there is still a gap between the first support rod 111 and the second support rod 121, which prevents the operator from having their hand pinched by the first support rod 111 and the second support rod 121 during the folding process of the support frame 100.

[0070] Please refer to Figures 7 and 8. Figure 7 is a second perspective view of the support frame 100 provided in an embodiment of this application; Figure 8 is a third perspective view of the support frame provided in an embodiment of this application. In some optional embodiments, the support frame 100 provided in an embodiment of this application may further include a connecting rod 140. One end of the connecting rod 140 may be detachably connected to the first gantry 110, and the other end of the connecting rod 140 may be detachably connected to the second gantry 120.

[0071] The detachable connection between the connecting rod 140 and the first mast 110 and the second mast 120 can be a snap-fit, screw-fit, or other method. Correspondingly, when the support frame 100 includes a third mast, a fourth mast, and a fifth mast, these masts can also be connected using the connecting rod 140. When the support frame 100 is unfolded, the connecting rod 140 can be assembled onto the mast. When the support frame 100 needs to be folded, the connecting rod 140 can be removed first, and then the first mast 110 and the second mast 120 can be brought closer together to achieve the folding of the support frame 100.

[0072] The support frame 100 shown in Figures 7 and 8 can both be configured as a tent frame. Among them, when the support frame 100 shown in Figure 8 is configured as a tent frame, it can be used as a triangular tent frame because its gantry is triangular.

[0073] The aforementioned detachable connecting rod 140 between the first gantry 110 and the second gantry 120 further ensures that the distance between the first gantry 110 and the second gantry 120 does not change when the support frame 100 is in the unfolded state, thereby further improving the stability of the support frame 100 in the unfolded state.

[0074] Referring to Figure 7, in some optional embodiments, the first gantry 110 may further include a first rotary connecting mechanism 112. The two connecting ends of the first rotary connecting mechanism 112 may be connected to the ends of two first support rods 111 respectively, and may be configured to achieve folding and unfolding between at least two first support rods 111. The second gantry 120 may further include a second rotary connecting mechanism 122. The two connecting ends of the second rotary connecting mechanism 122 may be connected to the ends of two second support rods 121 respectively, and may be configured to achieve folding and unfolding between at least two second support rods 121.

[0075] The first rotary connecting mechanism 112 can be any component or assembly in the related art capable of rotatably connecting two first support rods 111 together. The second rotary connecting mechanism 122 can be any component or assembly in the related art capable of rotatably connecting two second support rods 121 together.

[0076] The first rotary connecting mechanism 112 enables the folding and unfolding of the two first support rods 111 on the first gantry 110, and the second rotary connecting mechanism 122 enables the folding and unfolding of the two second support rods 121 on the second gantry 120, thus achieving the foldability of the first gantry 110 and the second gantry 120. During the folding process of the support frame 100, in addition to bringing the first gantry 110 and the second gantry 120 closer together via the folding assembly 130, folding can also be achieved through the inherent foldability of the first gantry 110 and the second gantry 120 themselves, further reducing the space occupied by the support frame 100 in the folded state.

[0077] Based on the same concept, this application also provides a tent, which may include tent fabric and the support frame 100 described above.

[0078] The tent fabric can be made of nylon, polyester, polyethylene, or cotton, etc. The tent fabric can be laid on the support frame 100 to form a tent.

[0079] The above implementation process is the same as that of the support frame 100 described above, and will not be repeated here.

[0080] In summary, the support frame 100 and tent provided in this application embodiment are connected to the first gantry 110 and the second gantry 120 respectively through the folding assembly 130. Since both the first telescopic rod 131 and the second telescopic rod 132 in the folding assembly 130 can be extended and retracted, when the first gantry 110 and the second gantry 120 approach each other, the first telescopic rod 131 and the second telescopic rod 132 only need to shorten their own length accordingly, without any connecting end on the folding assembly 130 sliding on the first support rod 111 or the second support rod 121. The connection position between the folding assembly 130 and the first support rod 111 and the second support rod 121 will not change. Accordingly, the situation where the support frame 100's support effect on the gantry decreases as the degree of unfolding increases will not occur, thereby improving the stability of the support frame 100 after unfolding. The first telescopic rod 131 and the second telescopic rod 132 are rotatably connected at their intersection. With the lengths of both the first telescopic rod 131 and the second telescopic rod 132 remaining constant, the first telescopic rod 131, the second telescopic rod 132, the first support rod 111, and the second support rod 121 form two fixed triangles. This prevents any two of the first telescopic rod 131, the second telescopic rod 132, the first support rod 111, and the second support rod 121 from moving relative to each other, thus further improving the stability of the support frame 100. By defining the first connecting end 1111 and the second connecting end 1112 as the two ends of the first support rod 111, and by defining the third connecting end 1211 and the fourth connecting end 1212 as the two ends of the second support rod 121, the supporting range of the folding assembly 130 on the gantry is maximized, thereby maximizing the stability of the support frame 100 in the unfolded state. By providing a first connecting part 1113 and a second connecting part 1213 on the first telescopic rod 131 and / or the second telescopic rod 132 respectively, the operator's hand is prevented from being pinched by the first support rod 111 and the second support rod 121 during the operation of folding the support frame 100.

[0081] In traditional support frames, especially those used in tents, the scissor assemblies between the gantry frames are fixed at one end and slidably connected at the other. This connection method affects the deployment range of the support frame, significantly increasing the material consumption for a support frame with the same deployment range. For example, the support rods in the gantry are typically designed to be around 1800mm long for ease of operation, while the length of the scissor assemblies can only be less than 1700mm (excluding the joint). When two gantry frames are deployed, the distance can only be pulled apart to about 1500mm. A 6m long tent would then require a total of 5 gantry frames. However, in the support frame provided in this application, the distance between two adjacent gantry frames can be extended to 2000mm, thus requiring only 4 gantry frames to achieve a tent length of 6m.

[0082] In traditional tent support frames, during deployment, the end of the scissor-mounted assembly that is slidably connected to the gantry tends to slide towards the end that is fixedly connected to the gantry. This results in a lack of support for the tent fabric on the sliding end, leading to a reduction in the snow load capacity of the tent fabric of the same thickness and strength. However, the support frame 100 provided in this embodiment, when configured as a tent support frame, increases the distance between the gantry frames and improves the uniformity of the distribution of the folding components 130 between the gantry frames. This enhances the evenness of the tent fabric support and improves the tent's snow load capacity.

[0083] Traditional support frames require a sliding locking and unlocking structure because one end of the scissor lift assembly slides when unfolding or folding, making operation more complicated. The support frame 100 provided in this embodiment eliminates the locking and unlocking operation and ensures better stability with the connecting rod 140.

[0084] Because the support frame 100 provided in this application embodiment can reduce the number and volume of gantry frames while maintaining the same tent length, it is more advantageous for various usage scenarios, especially mobile hospitals. Furthermore, it reduces manufacturing costs, which is beneficial for widespread application.

[0085] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application. Industrial applicability

[0086] In summary, this application provides a support frame and tent with a simple overall structure, low cost, and adaptability to various usage scenarios.
