Description

Technical Field

[0001] This utility model relates to the field of wind-resistant frame technology, specifically to a press lock for a wind-resistant frame. Background Technology

[0002] The application of displays is becoming increasingly widespread in outdoor advertising, exhibitions, and large-scale events. These scenarios often face complex environmental conditions, especially the impact of wind, which can cause displays to tilt, sway, or even collapse, seriously affecting safety and display effects. To increase the stability of displays, the industry standard practice is to install windproof frames on the back of the displays. Meanwhile, considering the convenience of moving and storing displays, foldable windproof frames have emerged.

[0003] However, current foldable windproof frames on the market have significant design flaws. Existing folding structures typically contain multiple complex mechanical parts, and the connection and locking mechanisms between these parts are cumbersome, resulting in complicated operation. Users need at least two hands to operate the windproof frame when unfolding and folding it, making single-handed operation difficult. When users are carrying a lot of items or working in confined spaces, the drawbacks of two-handed operation become apparent. The inconvenience not only wastes time and energy but also increases the risk of accidents.

[0004] In addition, the complex folding structure also means higher production costs and maintenance difficulties, which not only increases the product price and the economic burden on users, but also makes the repair work more complicated in the event of a failure, increasing the repair time and cost.

[0028] The present invention will be further described in conjunction with the following embodiments.

[0029] Depend on Figures 1 to 5 As can be seen, the push-lock for a wind-resistant frame described in this embodiment includes a positioning rod 1; the top of the positioning rod 1 is provided with an upper positioning pin 2; the bottom of the positioning rod 1 is provided with a lower positioning pin 3; the middle of the positioning rod 1 is provided with a trigger seat 4; the trigger seat 4 is provided with a push-button handle 5.

[0030] A linkage component is provided between the pressing handle 5, the upper positioning pin 2, the lower positioning pin 3, and the trigger seat 4;

[0031] The linkage assembly includes an upper lever 61, a lower lever 62, an upper pull rod 71, and a lower pull rod 72;

[0032] The middle part of the upper lever 61 is hinged to the trigger seat 4; one end of the upper lever 61 abuts against the pressing handle 5; the other end of the upper lever 61 is connected to the upper positioning pin 2 through the upper pull rod 71.

[0033] The lower lever 62 is hinged to the trigger seat 4 at its middle part; one end of the lower lever 62 abuts against the pressing handle 5; the other end of the lower lever 62 is connected to the lower positioning pin 3 through the pull rod 72.

[0034] Specifically, the push lock for the windproof frame described in this embodiment allows the windproof frame to be folded, unfolded, or have its angle changed when the windproof frame needs to be folded, unfolded, or have its angle changed. By pressing the push handle 5 inward toward the trigger seat 4, the push handle 5 moves one end of the upper lever 61 and one end of the lower lever 62, causing the other end of the upper lever 61 to move downward and the other end of the lower lever 62 to move upward. Then, the upper pull rod 71 and the lower pull rod 72 drive the upper positioning pin 2 and the lower positioning pin 3 to retract, thereby unlocking the windproof frame. This makes it easy to fold, unfold, or change the angle of the windproof frame.

[0035] This embodiment, by setting up an upper lever 61, a lower lever 62, an upper pull rod 71, and a lower pull rod 72, allows the user to control the windproof frame to be in an unlocked state by pressing the handle 5 with one hand. At this time, it is convenient to fold, unfold, or change the angle of the windproof frame, making it convenient for the user to use.

[0036] This embodiment describes a push-button lock for a wind-resistant frame. The top of the positioning rod 1 is provided with an upper limit seat 81; the upper limit seat 81 is provided with an upper limit groove 82; and the upper positioning pin 2 is telescopically movably disposed in the upper limit groove 82. Specifically, the above-mentioned arrangement can limit the telescopic movement of the upper positioning pin 2.

[0037] The push-lock for a windproof frame described in this embodiment includes an upper positioning pin 2 with an upper limit ring 21; an upper limit spring 22 is provided between the bottom of the upper limit ring 21 and the upper limit groove 82. With this configuration, in its natural state, under the action of the upper limit spring 22, the upper positioning pin 2 protrudes out of the upper limit groove 82, thereby locking the windproof frame.

[0038] The push-button lock for a wind-resistant frame described in this embodiment has an upper sliding seat 91 at the top of the upper limit seat 81; the upper sliding seat 91 has an upper channel 92 extending through it; and the upper positioning pin 2 protrudes from the upper channel 92. This configuration facilitates the movement of the driving positioning rod 1.

[0039] This embodiment describes a push-button lock for a wind-resistant frame. The bottom of the positioning rod 1 is provided with a lower limit seat 83; the lower limit seat 83 is provided with a lower limit groove 84; and the lower positioning pin 3 is telescopically movably positioned within the lower limit groove 84. Specifically, this configuration limits the telescopic movement of the lower positioning pin 3.

[0040] The push-lock for a windproof frame described in this embodiment includes a lower positioning pin 3 with a lower limiting ring 31; a lower limiting spring 32 is provided between the top of the lower limiting ring 31 and the lower limiting groove 84. With this configuration, in its natural state, under the action of the lower limiting spring 32, the lower positioning pin 3 protrudes out of the lower limiting groove 84, thereby locking the windproof frame.

[0041] The push-lock for a wind-resistant frame described in this embodiment has a lower sliding seat 93 at the bottom of the lower limit seat 83; the lower sliding seat 93 has a lower channel 94 extending through it; and the lower positioning pin 3 protrudes from the lower channel 94. This configuration facilitates the movement of the driving positioning rod 1.

[0042] The push-button lock for a wind-resistant frame described in this embodiment includes a trigger seat 4 with a guide groove 41 and a push-button handle 5 with a guide post 51. The guide post 51 is slidably disposed in the guide groove 41. This configuration guides and limits the movement of the push-button handle 5, and in its natural state, under the action of the upper limit spring 22 and the lower limit spring 32, the push-button handle 5 is in an extended position.

[0043] This embodiment describes a push-button lock for a wind-resistant frame. The push-button handle 5 is provided with a fixing pin 52; the fixing pin 52 is provided with a positioning block 53; the trigger seat 4 is provided with a positioning groove 42; and the positioning block 53 is slidably disposed in the positioning groove 42. This design prevents the push-button handle 5 from falling off the trigger seat 4.

[0044] This embodiment describes a push-button lock for a wind-resistant frame. The push-button handle 5 has an upper push-button post 54 and a lower push-button post 55. The upper push-button post 54 abuts against one end of the upper lever 61; the lower push-button post 55 abuts against one end of the lower lever 62. This arrangement facilitates the rotation of the upper lever 61 and the lower lever 62.
