Description

Technical Field

[0001] This invention relates to the field of folding tent parts technology, specifically a center lock for folding tents. Background Technology

[0002] A tent typically consists of a foldable tent frame and a tent fabric. The tent frame includes a canopy frame and multiple support legs. The support legs support the canopy frame, while the tent fabric covers the canopy frame, providing shade, rain protection, or wind protection. Folding tents use a locking mechanism to lock the tent in its unfolded state. Currently, the existing locking mechanism is mainly a button-type unlocking structure. This type of unlocking structure uses a button and an elastic element that applies elastic force to the button to lock the tent. However, this structure not only makes the entire unfolding and locking mechanism relatively complex, but also requires additional buttons and other structures during the unlocking process, affecting the overall appearance and resulting in poor unlocking stability. Summary of the Invention

[0003] The purpose of this invention is to provide a center lock for folding tents to solve the problems of complex unlocking structures and low unlocking stability mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a center lock for a folding tent, comprising a locking rod, a top plate, a base, and a rotating seat. The upper end of the locking rod is fixedly connected to the top plate, and a locking platform is integrally provided at the bottom of the locking rod. The base has a central hole for the locking rod to pass through, and a locking disc is attached to the bottom of the base. The locking disc has a locking groove adapted to the locking platform, and an elastic locking member with a latch is provided at the corresponding position of the locking groove. After the locking rod passes through the central hole, the latch, and extends into the locking groove, the elastic locking member abuts against and locks the latch. The rotating seat is rotatably connected to the base, and an opening arm is integrally provided on the rotating seat. The locking disc has a travel groove corresponding to the opening arm, allowing the opening arm to move with the rotation of the rotating seat. The opening arm extends from the travel groove into the latch, and by rotating the rotating seat, the opening arm opens the latch, causing the locking platform to disengage from the latch and unlock.

[0005] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention uses an elastic locking element to abut against the locking rod's locking platform to lock the platform in the locking groove, thereby locking the tent in its unfolded state; then, it employs a structure of a rotating seat, an opening arm on the rotating seat, and the opening arm extending into the locking slot of the elastic locking element, so that rotating the rotating seat causes the opening arm to move and open the elastic locking element, thereby achieving the disengagement and unlocking of the platform from the elastic locking element. The overall structure is simple, and the elastic locking element and the opening arm cooperate stably, resulting in high unlocking stability.

[0006] Preferably, the chassis base is integrally provided with limiting posts, the ends of the elastic locking members are respectively sleeved on each limiting post, and the locking disc is respectively connected with screws at each limiting post. The bottom of each limiting post is respectively opened with corresponding screw holes. The locking disc is fixedly connected to the chassis base by screws and limiting posts. The limiting posts can limit the elastic locking members and prevent them from shifting with the movement of the opening arm, thus affecting the stability of unlocking.

[0007] Preferably, the elastic element includes two parallel locking rods forming a latch between them. Simultaneously, the same end of the two locking rods is connected and closed to form a buffer head. The other end of each locking rod is integrally formed with a torsion spring structure. The buffer head can buffer damage to the locking rods during deformation. Furthermore, the torsion spring structure can improve the elasticity of the locking rods. When the opening arm opens the latch, the torsion spring structure can convert the force generated by the deformation of the locking rods into the torsional elastic force of the torsion spring structure, preventing the locking rods from deforming under stress after prolonged use, protecting the locking rods, and further improving the service life of the elastic element.

[0008] Preferably, the buffer head includes an arc-shaped rod, the two ends of which are integrally connected to the ends of the locking rod, and the limiting posts are respectively inserted inside the torsion spring structure.

[0009] Preferably, the buffer head includes two arc-shaped rods, two arc-shaped transition rods, and a connecting rod. The arc-shaped rods are respectively located on one side of the two locking rods. One end of the arc-shaped rod is integrally connected to the locking rod through the transition rod. The other ends of the two arc-shaped rods are integrally connected through the connecting rod. The limiting posts are respectively inserted inside the two sides of the buffer head and inside the torsion spring structure.

[0010] Preferably, the elastic element includes two parallel locking rods forming a latch between them. Simultaneously, one end of one locking rod and the opposite end of the other locking rod are integrally formed with a torsion spring structure. This torsion spring structure is sleeved on the corresponding limiting post. The torsion spring structure can convert the force generated by the deformation of the locking rod into the elastic force of the torsion spring structure, preventing the locking rod from deforming under stress after prolonged operation, protecting the locking rod, and further improving the service life of the elastic element.

[0011] Preferably, the torsion spring structure includes a sleeve and a torsion arm, which forms an angle with the locking rod, and the end of the torsion arm abuts against the inner wall of the chassis seat. The torsion spring structure generates elastic force when the locking rod deforms due to the abutment between the torsion arm and the inner wall of the chassis seat, thus protecting the locking rod.

[0012] Preferably, the distance between the two parallel locking rods is smaller than the size of the card table, which is beneficial for the elastic card to lock the card table.

[0013] Preferably, there is one opening arm, and the locking platform abuts and locks with one of the locking rods. By rotating the rotating seat towards the locking platform that abuts the locking rod, the opening arm opens the corresponding locking rod, so that the locking rod separates from the locking platform and achieves the unlocking effect.

[0014] Preferably, the rotating base is integrally provided with two symmetrical opening arms, and the locking platform is locked to the two locking rods. The travel groove is symmetrically arranged on both sides of the locking groove corresponding to the opening arms. That is, the opening arms are located on both sides of the locking groove. Therefore, whether the rotating base is rotated clockwise or counterclockwise, the locking slot can be quickly opened at the locking platform, so that the locking rod is separated from the locking platform, achieving a quick unlocking effect.

[0015] Preferably, the lower end face of the locking platform is spherical, which facilitates the locking rod to quickly enter the locking groove from the elastic locking member and be locked by the elastic locking member against the locking platform.

[0016] Preferably, a trapezoidal locking block is integrally formed on the top of the spreading arm, and the two ends of the bottom of the trapezoidal locking block form a limiting part between the spreading arm and the bottom of the spreading arm, so that the elastic locking piece can be prevented from disengaging from the spreading arm whether the rotating seat rotates clockwise or counterclockwise, thereby improving the stability of unlocking.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Specific Implementation Example 1

[0028] Please see Figure 1-4 This invention provides a technical solution: a center lock for a folding tent, comprising a locking rod 1, a top plate 2, a base plate 3, and a rotating base 4, wherein the upper end of the locking rod 1 is fixedly connected to the top plate 2, and the lower end of the locking rod 1 is detachably connected to the base plate 3. Specifically, to enable the center lock to maintain the tent in its unfolded state, the following is adopted:

[0029] The bottom of the locking rod 1 is integrally formed with a locking platform 1-1, the bottom end face of which is spherical. The base 3 is integrally provided with a central hole post 3-1 that can accommodate the locking rod 1. The bottom of the base 3 is fixedly connected with a locking plate 5. The locking plate 5 has a locking groove 5-1 below the central hole post 3-1 that is adapted to the locking platform 1-1. Furthermore, the locking plate 5 is provided with an elastic locking member 6 at the corresponding position of the locking groove 5-1. The elastic locking member 6 has a locking opening 6-1. The locking rod 1 passes through the central hole post 3-1 and the locking opening 6-1 in sequence and then extends into the locking groove 5-1. At this time, the elastic locking member 6 and the locking platform 1-1 are abutted and difficult to disengage. The elastic locking member 6 locks the locking rod 1. Moreover, the spherical shape of the locking platform 1-1 facilitates the locking rod 1 to enter the locking groove 5-1 from the elastic locking member 6 and is abutted and locked by the elastic locking member 6 and the locking platform 1-1.

[0030] The chassis base 3 is integrally provided with a limiting post 3-2. The end of the elastic locking member 6 is respectively sleeved on each limiting post 3-2, and the locking disc 5 is respectively connected with screws 7 at each limiting post 3-2. The bottom of each limiting post 3-2 is respectively opened with a corresponding screw hole 3-3. The locking disc 5 is fixedly connected to the chassis base 3 by screws 7 and limiting posts 3-2. The limiting post 3-2 can limit the elastic locking member 6 and prevent the elastic locking member 6 from shifting with the movement of the spreading arm 4-1, thus affecting the stability of unlocking.

[0031] The elastic element includes two parallel locking rods 6-2, forming a latch 6-1 between them. To ensure that the elastic latch 6 can reach the latch strip and lock in place, the distance between the two parallel locking rods 6-2 is less than the size of the latch platform 1-1. Simultaneously, the same end of the two locking rods 6-2 is connected and closed to form a buffer head 6-3. The other ends of the two locking rods 6-2 are integrally formed into torsion spring structures 6-4. The buffer head 6-3 includes an arc-shaped rod 6-3-1, the two ends of which are respectively connected to the locking rods 6-2. -2 The ends are integrally connected, and the limiting posts 3-2 are respectively inserted inside the torsion spring structure 6-4. The buffer head 6-3 can buffer the damage generated by the deformation of the locking rod 6-2. At the same time, the torsion spring structure 6-4 can improve the elasticity of the locking rod 6-2. When the spreading arm 4-1 spreads open the latch 6-1, the torsion spring structure 6-4 can convert the force generated by the deformation of the locking rod 6-2 into the torsional elastic force of the torsion spring structure 6-4, so as to avoid the locking rod 6-2 from being deformed after long-term operation, protect the locking rod 6-2, and further improve the service life of the elastic clip 6.

[0032] Furthermore, the torsion spring structure 6-4 includes a sleeve portion 6-4-1 and a torsion arm 6-4-2. The torsion arm 6-4-2 forms an angle with the locking rod 6-2, and the end of the torsion arm 6-4-2 abuts against the inner wall of the chassis base 3. The torsion spring structure 6-4 generates elastic force when the locking rod 6-2 deforms due to the abutment between the torsion arm 6-4-2 and the inner wall of the chassis base 3, thus protecting the locking rod 6-2.

[0033] In addition, a trapezoidal locking block 4-2 is integrally formed on the top of the spreading arm 4-1. The two ends of the bottom of the trapezoidal locking block 4-2 form a limiting part between the spreading arm 4-1, so that the rotating seat 4 can prevent the elastic locking piece 6 from disengaging from the spreading arm 4-1 whether it rotates clockwise or counterclockwise, thus improving the stability of unlocking.

[0034] To achieve a stable unlocking effect, the rotating seat 4 is rotatably connected to the bottom of the chassis seat 3. The outer wall of the rotating seat 4 is evenly provided with anti-slip texture 4-3. The rotating seat 4 is provided with a supporting arm 4-1. The locking disc 5 is provided with a travel groove 5-2 corresponding to the supporting arm 4-1, which can accommodate the supporting arm 4-1 to move with the rotating seat 4. The supporting arm 4-1 extends into the bayonet 6-1 from the travel groove 5-2. By rotating the rotating seat 4, the supporting arm 4-1 is driven to open the bayonet 6-1, so that the locking platform 1-1 is disengaged from the bayonet 6-1 and unlocked, thereby achieving the unlocking effect.

[0035] In this specific embodiment, two symmetrical opening arms 4-1 are integrally provided on the rotating base 4. The locking platform 1-1 is engaged with two locking rods 6-2. The travel groove 5-2 is symmetrically arranged on both sides of the locking groove 5-1 corresponding to the opening arms 4-1. That is, the opening arms 4-1 are located on both sides of the locking groove 5-1. Therefore, whether the rotating base 4 is rotated clockwise or counterclockwise, the locking slot 6-1 can be quickly opened at the locking platform 1-1, so that the locking rod 1 is separated from the locking platform 1-1, achieving a quick unlocking effect.

[0036] In addition, the bottom end face of the rotating base 4 is integrally formed with a snap-fit ​​part, and a hook 8 is snapped into the bottom end face of the rotating base 4 through the snap-fit ​​part, which facilitates user assembly and unlocking. Specific Implementation Example 2

[0038] like Figure 5 As shown, the difference between this specific embodiment and specific embodiment 1 is that the buffer head 6-3 of the elastic element includes two arc-shaped rods 6-3-1, two arc-shaped transition rods 6-3-2, and a connecting rod 6-3-3. The arc-shaped rods 6-3-1 are respectively located on one side of the two locking rods 6-2. One end of the arc-shaped rod 6-3-1 is integrally connected to the locking rod 6-2 through the transition rod 6-3-2. The other ends of the two arc-shaped rods 6-3-1 are integrally connected through the connecting rod 6-3-3. The limiting post 3-2 is respectively inserted inside the two sides of the buffer head 6-3 and inside the torsion spring structure 6-4. Specific Implementation Example 3

[0040] like Figure 6-7As shown, the difference between this specific embodiment and specific embodiment 1 is that the elastic element includes two parallel locking rods 6-2, forming a bayonet 6-1 between the two locking rods 6-2. Simultaneously, one end of one locking rod 6-2 and the opposite end of the other locking rod 6-2 are integrally formed with a torsion spring structure 6-4. The torsion spring structure 6-4 includes a sleeve portion 6-4-1 and a torsion arm 6-4-2. The torsion arm 6-4-2 forms an angle with the locking rod 6-2, and the end of the torsion arm 6-4-2 abuts against the inner wall of the chassis base 3. Limiting posts 3-2 are respectively inserted through the sleeve portion 6-4-1 for limiting movement. The torsion spring structure 6-4 can prevent the locking rod 6-2 from bending or deforming, protecting the locking rod 6-2 and further improving the service life of the elastic clamp 6. Specific Implementation Example 4

[0042] like Figure 8 As shown, the difference between this specific embodiment and specific embodiment 1 is that the number of the opening arm 4-1 is one, and the locking platform 1-1 is locked to one of the locking rods 6-2. By rotating the rotating seat 4 toward the locking platform 1-1 that is abutting the locking rod 6-2, the opening arm 4-1 is driven to open the corresponding locking rod 6-2, so that the locking rod 6-2 is separated from the locking platform 1-1, thereby achieving the unlocking effect.
