Description

Technical Field

[0001] This application relates to the field of outdoor products, and in particular to a folding tent pole. Background Technology

[0002] Outdoor sports, such as mountaineering, hiking, and camping, are becoming increasingly popular. Folding tent poles, as key equipment for these activities, are widely used in products such as tent poles and photography support poles. Users' core requirements for this equipment are: high reliability and stability in the unfolded state to ensure safety, and the ability to fold and store quickly and conveniently to save carrying space.

[0003] Currently, existing folding tent poles on the market have undergone various attempts in connection and locking structures, but they generally suffer from some common technical challenges. The folding mechanisms of many existing products are not simple or intuitive to operate, failing to achieve rapid unfolding and storage, thus reducing usage efficiency. More importantly, the locking reliability of some structures is insufficient, posing a risk of accidental loosening or folding when subjected to loads or external vibrations and impacts, creating safety hazards for users. Furthermore, some structures exhibit weak connection rigidity and poor stability after unfolding, affecting transmission efficiency and user experience. Utility Model Content

[0004] The purpose of at least one specific embodiment of this utility model is to overcome the defects of the existing technology and provide a folding tent pole.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A folding tent pole, comprising a first pole body and a second pole body; Also includes: The first connector is fixedly connected to the first rod. The second connector is fixedly connected to the second rod and is connected to the first connector via a pivot. Rotary connection of parts; The first connector and the second connector are provided with positioning components that cooperate with each other at their opposite ends. When the first rod and the second rod rotate to the unfolded state, the positioning components engage with each other to prevent the first connector and the second connector from continuing to rotate relative to each other. A locking sleeve that can move axially is provided on the first or second connector. The locking sleeve is driven by an elastic force and is normally held in a first position that covers and locks the positioning component. When the locking sleeve is activated to overcome the spring force and move to a second position that exposes and releases the positioning component, the locking of the positioning component can be released.

[0006] Furthermore, the positioning component includes a positioning recess disposed on one of the first connector and the second connector, and a positioning protrusion disposed on the other and adapted to the positioning recess.

[0007] Furthermore, the positioning recess is a limiting groove, and the positioning protrusion is a limiting block.

[0008] Furthermore, both the locking sleeve and the positioning recess are provided on the first connector. In the first position, the end of the locking sleeve covers the entrance of the positioning recess, forming a mechanical barrier to prevent the positioning protrusion from dislodging from the positioning recess.

[0009] Furthermore, in the second position, the locking sleeve moves axially and avoids the entrance of the positioning recess, providing a path for the positioning protrusion to disengage from the positioning recess.

[0010] Furthermore, the positioning recess includes a limiting surface located at its bottom for abutting against the positioning protrusion to achieve axial positioning, and an opening groove located at its top, the profile of which is adapted to the positioning protrusion for sliding in and out; the locking sleeve covers at least a portion of the opening groove in the first position.

[0011] Furthermore, when the positioning protrusion abuts against the limiting surface, the axes of the first rod and the second rod are confined to the same straight line.

[0012] Furthermore, the locking sleeve is mounted on the first connector, and the elastic force is provided by an elastic element that acts between the locking sleeve and a support portion fixed to the first connector.

[0013] Furthermore, when the first rod and the second rod rotate relative to each other around the pivot to the unfolded state, the positioning protrusion slides into the opening groove of the positioning recess and abuts against the limiting surface; When the first rod and the second rod rotate relative to each other to the folded state, the positioning protrusion slides out of the positioning recess along the opening groove.

[0014] Furthermore, the positioning protrusion is positioned on the second connector at a predetermined radial distance from the axis of the pivot, so that when the positioning protrusion abuts against the limiting surface, a stable mechanical lock is formed.

[0015] Compared with the prior art, the beneficial effects of this application are as follows: 1. This application achieves the function of "one-click unlocking" by setting an axially movable locking sleeve driven by elastic force. Users only need to simply touch (such as pressing or flicking) the locking sleeve to release the locked state and perform folding or unfolding operations. The action is simple and intuitive, which greatly improves the efficiency of state transition and the convenience of operation; 2. The engagement of the positioning components during the unfolding of the rod directly and effectively prevents relative rotation between the first and second connecting parts, ensuring the stability of the unfolded state. Combined with the locking sleeve covering and locking the positioning components under the action of elasticity, a double insurance mechanism is formed, effectively preventing accidental folding caused by vibration, impact, or misoperation, greatly enhancing reliability.

[0028] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] Reference Figure 1 , Figure 2 , Figure 3 This embodiment discloses a folding tent pole 100, which mainly includes a first pole body 10 and a second pole body 20. The two are connected by a connecting mechanism to achieve relative rotation and locking. The angle can be flexibly adjusted according to the usage requirements to achieve the functions of quick folding and stable unfolding.

[0030] The connecting mechanism includes a first connector 30 located at the end of the first rod 10 and a second connector 40 located at the end of the second rod 20. The first rod 10 is typically made of lightweight, high-strength aluminum alloy or composite material, and one end is securely connected to the first connector 30 via mechanical fixing or interference fit. Similarly, the second rod 20 is made of the same material and manufactured using the same process as the first rod, and its corresponding end is fixedly connected to the second connector 40. The first connector 30 and the second connector 40 are connected by a high-strength pivot 60, which ensures durability and reliability under repeated use and heavy loads. This connection method allows the first rod 10 and the second rod 20 to rotate relative to each other around the pivot 60, providing users with convenient angle adjustment and storage capabilities, making it particularly suitable for outdoor applications such as sunshade or tent poles.

[0031] Specifically, refer to Figure 4 , Figure 5 , Figure 6 The first connector 30 includes a first rotating connection portion 301 and a first connecting portion 302, which are integrally formed or separately. Similarly, the second connector 40 includes a second rotating connection portion 401 and a second connecting portion 402. The first rotating connection portion 301 is provided with a precision-formed mounting opening 303, the shape and size of which match the connecting body 403 on the second rotating connection portion 401.

[0032] In the assembled state, the connecting body 403 of the second rotating connecting part 401 extends into the mounting port 303 of the first rotating connecting part 301, and the two are rotated together by the pivot 60 to ensure that the rotation process is smooth and without shaking.

[0033] The first rod 10 is fixed to the first connector 30 by inserting the end of the first rod 10 into the first connector 302 and fastening it with a first fastener 200. The first fastener 200 is preferably a hexagonal socket head cap screw or a screw, providing sufficient clamping force and preventing loosening. Similarly, the second rod 20 is connected to the second connector 40 by inserting the end of the second rod 20 into the second connector 402 and fixing it with a second fastener 300. The second fastener 300 is also preferably a hexagonal socket head cap screw or a screw, providing sufficient clamping force and preventing loosening. To prevent circumferential rotation between the first rod 10 and the first connector 30, the outer wall of the first rod 10 and the inner wall of the first connector 30 are provided with mutually cooperating first limiting planes 10a. These limiting planes are milled or molded to ensure precise fit. Similarly, the outer wall of the second rod 20 and the inner wall of the second connector 40 are provided with a second limiting plane 20a, which effectively suppresses circumferential rotation through planar cooperation, ensuring the stability of the rod posture and the directness of force transmission during use.

[0034] To further define the unfolded state, continue to refer to... Figure 5 To improve the stability and continuity of the unfolding of the first rod 10 and the second rod 20, the first rotating connection portion 301 and the second rotating connection portion 401 are provided with a limiting block 404 and a limiting groove 304, respectively. The limiting block 404 and the limiting groove 304 are constructed as a specific embodiment of a positioning assembly, that is, the positioning assembly includes a positioning recess on one and a positioning protrusion on the other. In this embodiment, the positioning recess is the limiting groove 304, and the positioning protrusion is the limiting block 404.

[0035] In this embodiment, a limiting block 404 is disposed on the second rotating connection portion 401. It is a protruding structure that can be manufactured by stamping, casting, or machining. A limiting groove 304 is located on the first rotating connection portion 301 and extends to the area of ​​the first connecting portion 302. Its contour is complementary to that of the limiting block 404. A limiting surface 304a is provided at the bottom of the limiting groove 304, which can effectively prevent further movement of the limiting block 404. The top of the limiting groove 304 is provided with an opening groove 304b, which facilitates the entry and exit of the limiting block 404. When the first rod 10 and the second rod 20 are fully extended and their axes are on the same straight line, the limiting block 404 is embedded in the limiting groove 304, and the limiting surface 304a abuts against the limiting block 404, preventing it from continuing to rotate, thereby keeping the two rods in a stable straight state. The axes of the first rod 10 and the second rod 20 are limited to the same straight line, and no accidental bending will occur when bearing axial load. Moreover, the positioning protrusion (limiting block 404) on the second connector 40 has a predetermined radial distance from the axis of the pivot 60, so that when the positioning protrusion (limiting block 404) abuts against the limiting surface 304a, a solid mechanical lock is formed, which greatly enhances the stability of the extended state.

[0036] To improve reliability and safety, an elastic element 70 and a locking sleeve 80 are sequentially fitted onto the outside of the first connecting portion 302. A support portion 305 is provided at the end of the first connecting portion 302. This support portion 305 can be fixed to the end as an independent component by a first fastener 200, or it can be integrally formed with the first connecting portion 302. The locking sleeve 80 is typically made of engineering plastic or metal, and its inner wall has a boss 801 for positioning the elastic element 70. The elastic element 70 is typically a stainless steel compression spring or disc spring, which is installed between the locking sleeve 80 and the support portion 305 to provide continuous restoring force.

[0037] Reference Figure 7 , Figure 8 , Figure 9 During assembly, first, the locking sleeve 80 is fitted onto the outside of the first connecting portion 302, then the elastic element 70 is fitted onto the outside, with one end abutting against the boss 801, and finally the support portion 305 is installed to support the other end of the elastic element 70. After assembly, the locking sleeve 80 can slide axially along the first connecting portion 302. In its natural state, the elastic force of the elastic element 70 keeps the locking sleeve 80 in a position covering a portion of the limiting groove 304. That is, the locking sleeve 80 is in the first position covering and locking the positioning assembly. When the tent poles are fully extended, the limiting block 404 is located within the limiting groove 304, and the locking sleeve 80 covers its exterior. Its end covers the entrance (i.e., the opening groove 304b) of the positioning recess (limiting groove 304), forming a mechanical barrier to prevent the positioning protrusion (limiting block 404) from dislodging from the positioning recess (limiting groove 304), thus forming a mechanical lock. This effectively prevents the limiting block 404 from dislodging, avoids accidental folding of the two poles, and greatly improves the safety and reliability of use, especially in steep or slippery environments. Moreover, the locking sleeve 80 always covers the locking component under normal conditions, forming a physical barrier. This not only plays a role in mechanical locking but also prevents mud and sand from entering the limiting groove 304 to a certain extent, improving the product's adaptability to harsh environments and its long-term safe service life.

[0038] Reference Figure 10When the user needs to change the tent pole from the unfolded state to the folded state, they must first touch (e.g., press) the locking sleeve 80 by hand, causing it to slide towards the support part 305. At this time, the elastic element 70 is compressed, and the locking sleeve 80 gradually disengages from the limiting groove 304 area, that is, moves to the second position where the positioning component is exposed and released. In this position, the locking sleeve 80 moves axially and avoids the entrance (opening groove 304b) of the positioning recess (limiting groove 304), providing a path for the positioning protrusion (limiting block 404) to disengage from the positioning recess, thus releasing the covering restriction on the limiting block 404. Subsequently, the user holds the second pole body 20 and rotates it in the first direction W1, causing the first connecting member 30 and the second connecting member 40 to rotate relative to each other around the pivot 60. The positioning protrusion (limiting block 404) slides out of the positioning recess (limiting groove 304) along the opening groove 304b, that is, the limiting block 404 disengages from the opening groove 304b at the top of the limiting groove 304. After the locking sleeve 80 is released, the elastic element 70 rebounds, pushing the locking sleeve 80 back to its original position. At this time, the two rods can rotate freely relative to each other, achieving compact folding, which is convenient for storage and carrying. The entire folding process is simple and intuitive to operate.

[0039] Reference Figure 11 When the tent poles need to be returned to their unfolded state, the user holds the second pole 20 and rotates it in a second direction W2, opposite to the first direction W1. The two poles rotate relative to each other around the pivot 60 until the limiting block 404 approaches the limiting groove 304. At this point, the locking sleeve 80 needs to be touched (e.g., pressed) again to avoid the entrance of the limiting groove 304, allowing the limiting block 404 to smoothly embed into the limiting groove 304. When the axes of the two poles return to the same straight line, the limiting surface 304a prevents the limiting block 404 from continuing to rotate, ensuring that the unfolding angle is 180°. After releasing the locking sleeve 80, the elastic element 70 pushes it back to its original position, re-covering the limiting groove 304 and the limiting block 404, restoring the mechanical locking state and preventing accidental folding. This process is accompanied by a clear sense of completion, providing the user with clear feedback.

[0040] The folding tent pole achieves precise positioning and angle maintenance in its unfolded state through the structural cooperation of the limiting groove and the limiting part. The locking mechanism, consisting of the locking sleeve 80 and the elastic element 70, provides continuous locking force under normal use, effectively preventing accidental folding of the pole due to external impact, vibration, or misoperation, significantly improving the product's safety and reliability. At the same time, the overall structure also considers ease of operation, allowing users to easily complete the state transition.

[0041] In summary, the folding tent pole structure provided by this utility model has a reasonable design, is easy and intuitive to operate, and its folding and unfolding actions are reliable, exhibiting good stability, safety, and durability. It can be widely used in outdoor leisure, sports, and industrial fields such as tent poles, sunshade brackets, and photography support poles, possessing high practical value and market prospects.
