Description

Technical Field

[0001] This application relates to the field of fastener technology, and in particular to a locking structure and a telescopic canopy pole. Background Technology

[0002] As one of the main sheltering equipment in outdoor camping, awnings are widely used for sunshade, sun protection, and rain protection, effectively improving the comfort of the camping environment. The construction of awnings typically relies on awning poles for support. These poles not only need good strength and stability but also need to be telescopic and adjustable to adapt to different terrains and usage needs. Existing awning pole adjustment methods mostly achieve this through rotation locking or pin positioning. For example, Chinese Utility Model Publication CN219754214U discloses an external locking pole for awnings, where the locking relationship between two adjacent poles is achieved by a switch body set on the pole. Users can control the engagement state between the limiting post and the limiting hole on the other side by pressing one side of the plate buckle on the switch body, thereby adjusting or locking the awning pole. However, this structure has the following problems:

[0003] 1. When the plate buckle is subjected to accidental collision or impact, the limiting post is very likely to come out of the limiting hole, causing the two adjacent rods to unexpectedly contract under the action of external force, lose support, and pose a safety hazard;

[0004] 2. When adjusting the length of the canopy pole, the user needs to press the buckle along the radial direction of the pole with their thumb. This operation can easily lead to thumb fatigue and soreness, affecting the comfort of use. Summary of the Invention

[0005] This application provides a locking structure and a telescopic canopy rod. The locking structure according to this application can overcome at least one or more problems existing in the prior art.

[0006] A first aspect of this application provides a locking structure, including a housing, a lock head, a push plate, and a retainer. The retainer is used to maintain the push plate's tendency to move towards the head of the lock head, and the movement of the push plate can drive the lock head to rotate relative to the housing.

[0007] When the push plate moves toward the head of the lock cylinder, the head of the lock cylinder rotates downwards.

[0008] When the push plate moves toward the tail of the lock head, the lock head rotates upward.

[0009] In one possible implementation, the retainer is elastic and disposed between the push plate and the housing, capable of driving the push plate to move toward the lock head: when the push plate moves away from the lock head under the action of an external force, the retainer is compressed; after the external force is removed, the retainer pushes the push plate to move toward the lock head to reset.

[0010] In one possible implementation, the lock head is bent in the middle, with the middle side rotatably connected to the housing; when the tail of the lock head approaches the housing, the head of the lock head is in a raised position.

[0011] In one possible implementation, the lock includes a plug, a rocker arm, and a shaft. The plug and rocker arm are angled together, and the shaft is located on the side of their connection point. The shaft is rotatably connected to the housing, and the bottom of the plug has a pin that mates with a limiting hole on the canopy pole.

[0012] When the rocker arm moves towards the housing, the pin is located outside the limiting hole on the canopy pole; when the plug is pressed down, causing the rocker arm to tilt, the pin enters the limiting hole on the canopy pole.

[0013] In one possible implementation, the housing includes a sleeve and a groove. The sleeve is cylindrical and is fitted around the outer periphery of one side of the canopy pole. The groove is provided on the outside of the sleeve. A lock head, a push plate, and a retainer are installed inside the groove. A through hole is provided between the sleeve and the groove to allow a pin on the lock head to pass through.

[0014] In one possible implementation, the push plate has a recess on the side facing the retainer, the retainer is a spring and is inserted into the recess, and the outer end of the spring abuts against the inner wall of the recess.

[0015] In one possible implementation, the bottom surface of the push plate facing the lock head is sloped and remains pressed against the lock head.

[0016] In one possible implementation, the top of the tank is provided with a cover, which has a window that allows the top of the push plate to pass through and move within it.

[0017] In a second aspect, this application also provides a telescopic canopy pole, which includes the aforementioned locking structure. The locking structure is disposed on one side of the pole body and is used to constrain the positional relationship between the pole body and adjacent pole bodies.

[0018] Compared with the prior art, the present invention has the following advantages: the user can hold one section of the rod with four fingers, hook the push plate of the locking structure with the thumb, and pull the other unrestrained rod with the other hand. The thumb does not need to apply extra pressure, but only needs to keep it in a bent state, which provides a good user experience and avoids thumb fatigue and soreness.

[0019] This locking mechanism is an externally pushed locking mechanism, which avoids the risk of the locking mechanism flipping and failing due to external impact.

[0020] It should be noted that any of the possible implementations of any of the above aspects can be combined, provided that the solutions do not contradict each other. Attached Figure Description

[0027] The present application will now be described with reference to the accompanying drawings, which illustrate several embodiments of the present application. However, it should be understood that the present application can be presented in many different ways and is not limited to the embodiments described below; in fact, the embodiments described below are intended to make the disclosure of the present application more complete and to fully illustrate the scope of protection of the present application to those skilled in the art. It should also be understood that the embodiments disclosed herein can be combined in various ways to provide more additional embodiments.

[0028] On the one hand, embodiments of this application provide a locking structure, which can be referred to in conjunction with the following: Figure 1 and Figure 3 The system includes a housing 10, a lock head 20, a push plate 30, and a retainer 40. The retainer 40 is used to maintain the push plate 30 in a tendency to move towards the head of the lock head 20. Movement of the push plate 30 can drive the lock head 20 to rotate relative to the housing 10.

[0029] When the push plate 30 moves toward the head of the lock cylinder 20, the head of the lock cylinder 20 rotates downward.

[0030] When the push plate 30 moves toward the tail of the lock head 20, the head of the lock head 20 rotates upward.

[0031] Specifically, the retainer 40 is elastic and is disposed between the push plate 30 and the housing 10, used to drive (push or pull) the push plate 30 to move towards the lock head 20. When the push plate 30 moves away from the head of the lock head 20 under the action of external force, the retainer 40 is compressed by force; after the external force is removed, the retainer 40 relies on its own elastic restoring force to push the push plate 30 to move back to the lock head 20 and reset.

[0032] As described above, the lock head 20 is bent in the middle, and the middle side is rotatably connected to the housing 10; when the tail of the lock head 20 is against the housing 10, the head of the lock head 20 is in a raised state, and at this time it cannot form a constraint relationship with the limiting hole on the rod.

[0033] Please refer to the following for details. Figure 2 and Figure 3 The lock cylinder 20 includes a plug 21, a rocker arm 22, and a shaft 23, all three being integrally formed. Both the plug 21 and the rocker arm 22 are plate-shaped structures, set at a certain angle. A shaft 23 is located on the side of the connection between the two, and the shaft 23 is rotatably connected to the housing 10. A pin (which can be integrally formed with the plug 21) is located at the bottom of the plug 21, for engaging with a limiting hole on the shaft.

[0034] When the rocker arm 22 approaches the housing 10, the pin is located outside the limiting hole of the rod body; when the plug 21 is pressed down, causing the rocker arm 22 to tilt up, the pin enters the limiting hole of the rod body.

[0035] Specifically, the housing 10 includes a sleeve 11 and a groove 12. The sleeve 11 has a cylindrical structure and is fitted around the outer periphery of one side of the canopy pole. The groove 12 is provided on the outside of the sleeve 11, and the interior of the groove 12 is used to install the lock head 20, the push plate 30, and the retainer 40. A through hole 13 is provided between the sleeve 11 and the groove 12, which allows the pin on the lock head 20 to pass through.

[0036] Specifically, the push plate 30 has a recess 31 on the side facing the retainer 40, and the retainer 40 is a spring inserted into the recess 31. The outer end of the spring abuts against the inner wall of the groove 12, which further stabilizes the spring; the bottom surface of the push plate 30 facing the lock head 20 has a pressing head 32 with an inclined surface, which is used to press against the lock head 20 to prevent the push plate 30 from getting stuck when it moves towards the head of the lock head 20.

[0037] In practical applications, the top of the tank 12 is provided with a cover 50 to protect the internal components. The cover 50 has a window that allows the top of the push plate 30 to pass through and move within it.

[0038] Embodiments of this application also provide a telescopic awning pole, which includes the aforementioned locking structure. Please refer to... Figure 4The locking structure is located on one side of the primary pole 60 of the canopy pole and is used to constrain the positional relationship between it and the adjacent secondary pole 70, thereby enabling the lock head 20 to lock or release the two adjacent poles.

[0039] In use, the locking structure of this application is pre-set on the part of the primary rod 60 that connects to the secondary rod 70. When adjusting the extension / retraction, the user only needs to pull the push plate 30 backward, causing it to press against the tail of the lock head 20, thus disengaging the pin at the head of the lock head 20 from the limiting hole of the secondary rod 70. At this time, the user can hold the rod with four fingers, hook the push plate 30 backward with their thumb, and pull the secondary rod 70 with their other hand. Throughout the operation, the thumb does not need to exert force; it only needs to be held in a bent state, providing a good user experience and avoiding thumb fatigue and soreness. After adjusting to the appropriate position, the push plate 30 is released. Under the elastic restoring force of the retainer 40, the push plate 30 moves towards the head of the lock head 20, and the pin re-inserts into the limiting hole of the secondary rod 70, completing the locking process.

[0040] Furthermore, this locking structure improves upon the traditional flip-locking mechanism in the prior art by replacing it with an external push-type locking mechanism, thus avoiding the risk of the locking mechanism failing due to external impact.

[0041] While exemplary embodiments of this application have been described, those skilled in the art will understand that various changes and modifications can be made to the exemplary embodiments of this application without departing from the spirit and scope thereof. Therefore, all changes and modifications are included within the scope of protection of this application as defined by the claims. This application is defined by the appended claims, and equivalents of those claims are also included.
