[0024] In order to make those skilled in the art better understand the technical scheme of the present application, the present application will be further described in detail in combination with the drawings.

[0025] Please refer to Figures 1-8 Please refer to Figures 1 to 7The utility model relates to an automatic retractable outdoor portable quadrat frame device, and its core structure comprises a support column 1. The support column 1 is an important support component of the whole device, and two carefully designed support plates are fixedly connected inside the support column 1. The two support plates play a key role in supporting and positioning in the internal space of the support column 1. Between the two support plates, a connecting rod 4 is connected in a rotating manner, and the connecting rod 4 can rotate freely around the connecting point with the support plates, thereby laying a foundation for the folding function of the device. In particular, a set of locking mechanisms are carefully arranged at the top of the connecting rod 4, which are precisely installed in the upper area inside the support column 1, and the main function is to precisely lock the rotation of the connecting rod 4, ensuring the stability and reliability of the device in different states (such as the unfolded use state or the folded storage state).

[0026] In the locking mechanism of the utility model, a plurality of components work together. The ratchet 8 is fixedly connected to the top end of the connecting rod 4, and has a special toothed structure that can cooperate with other components to achieve a specific locking function. The balance bar 9 is rotatably connected to the upper support plate, and plays an important role in balancing and force transmission in the whole locking mechanism. The ratchet 10 is rotatably connected to the balance bar 9, and one end of the ratchet 10 is precisely engaged with the ratchet 8. When the device is in the unfolded state, the ratchet 10 tightly engages the ratchet 8 under the action of the return spring 12, preventing the connecting rod 4 from rotating accidentally, thereby ensuring the stability of the frame structure and the accuracy of the sampling range; when the device needs to be folded, the operating rod 11 can overcome the elastic force of the return spring 12 to make the ratchet 10 disengage from the ratchet 8, thereby allowing the connecting rod 4 to rotate smoothly and achieving the folding of the device.

[0027] Further, a spring hole is carefully formed on one side of the ratchet 10, and the return spring 12 is fixedly connected inside the spring hole. The return spring 12 is always in a stressed state, and the direction of its elastic force is to keep the ratchet 10 tightly engaged with the ratchet 8. An installation hole is precisely formed on one side of the support column 1, and the operating rod 11 is movably sleeved inside the installation hole. One end of the operating rod 11 is fixedly connected with the return spring 12, and the other end extends to the outside of the support column 1, facilitating the user to operate. When the user needs to adjust the state of the device, he only needs to press or pull the operating rod 11 to indirectly control the engagement relationship between the ratchet 10 and the ratchet 8 through the return spring 12, thereby achieving the locking or unlocking of the rotation of the connecting rod 4.

[0028] Looking at other parts of the device, the outside of the support column 1 is fixedly and regularly connected with a plurality of clamping grooves 13 in an array, which provides important assistance for the wire storage function of the device. The connecting rod 4 is fixedly connected with a winding roller 5, and the outside of the winding roller 5 is tightly wound with a scale tape 6. One end of the scale tape 6 is fixedly connected with the winding roller 5, which ensures that the wire will not fall off during winding. The other end of the scale tape 6 is fixedly connected with a clamping plate 7, which can be accurately sleeved in the inside of the clamping groove 13. After the wire is wound on the winding roller 5, the clamping plate 7 is inserted into the appropriate clamping groove 13, which can effectively fix the position of the wire and prevent the wire from loosening during storage, ensuring the neatness and stability of the storage. One end of the connecting rod 4 is provided with a volute spring, which automatically winds the winding roller 5, so as to drive the connecting rod 4 to rotate after the return spring 12 is loosened, and automatically shrinks the scale tape back to the inside of the support column.

[0029] In addition, the top of the support column 1 is ingeniously provided with a first threaded hole, and a top cover 2 is accurately threaded in the first threaded hole. The outside of the top cover 2 is regularly provided with first anti-skid lines in an array, which can increase the friction between the user's hand and the top cover 2 when rotating the top cover 2, facilitating the opening and closing of the top cover 2. At the same time, the top of the top cover 2 is carefully provided with a marking groove, in which the user can mark the type and purpose of the wire, etc., to facilitate quick identification and use of the required wire. The bottom of the support column 1 is also carefully provided with a second threaded hole, and a support leg 3 is accurately threaded in the second threaded hole. The cross section of the support leg 3 is designed as a cone, which can provide more stable support effect. The support leg 3 is regularly provided with second anti-skid lines in an array, which further enhances the friction between the support leg 3 and the placement plane, ensuring that the device will not easily slide or fall when placed, effectively protecting the wires stored in the device.

[0030] Working principle: in the initial state, the device is in a folded state. When it is needed to be unfolded and used, the folded part is unfolded, and the connecting rod 4 rotates around the connecting point with the support plate. At this time, since the ratchet 10 is tightly engaged with the ratchet wheel 8 under the elastic force of the return spring 12, the reverse rotation of the connecting rod 4 is prevented, so that the device can stably maintain in the unfolded state, forming a stable square frame structure, which is convenient for placing and arranging the wires.

[0031] Specifically, the ratchet 10 forms a movable connection structure with the support plate inside the support column 1 through the balance bar 9. When the connecting rod 4 rotates, the ratchet 8 connected thereto also rotates, and the ratchet 10 always maintains engagement with the ratchet 8 under the action of the return spring 12, preventing reverse rotation and ensuring the stability of the device after deployment.

[0032] First, fix one end of the wire to be stored on the winding roller 5, then manually rotate the winding roller 5 to make the wire evenly wind on the scale tape 6 outside the winding roller 5. The scale tape 6 is similar in structure to a common tape measure, and can flexibly wind the wire as the winding roller 5 rotates, and can automatically adjust the number of layers wound according to the length of the wire.

[0033] When the wire is stored, insert the clamping plate 7 at the other end of the scale tape 6 into the clamping groove 13 at a suitable position outside the support column 1. The array distribution of the clamping groove 13 can adapt to the storage needs of wires of different lengths. By inserting the clamping plate 7 into the clamping groove 13, the clamping groove 13 not only serves to fix the clamping plate 7 during storage, but more importantly serves to receive and fix the clamping plate 7 and the scale tape from other support columns during deployment, which can effectively fix the position of the scale tape 6, prevent the wire from loosening or falling off after storage, and ensure the neatness and stability of the wire storage.

[0034] When the folding device needs to be stored or carried, the user presses or pulls the operating rod 11. The movement of the operating rod 11 stretches the return spring 12, causing the ratchet 10 indirectly connected to the operating rod 11 to rotate against the elastic force of the return spring 12, thereby causing the ratchet 10 to disengage from the ratchet 8.

[0035] At this time, the connecting rod 4 is no longer restricted by the locking mechanism and can rotate freely. The user can rotate the connecting rod 4 to a suitable folding position to make the device fold into a compact shape for easy storage and carrying. During folding, since the wire on the winding roller 5 has been fixed by the clamping plate 7 and the clamping groove 13, the wire will not spread out and will remain neatly stored.

[0036] The top cover 2 is connected to the first threaded hole at the top of the support column 1 by threading. After storing the wire, the top cover 2 is rotated and tightened on the top of the support column 1, which can effectively prevent the wire from falling off from above, and also serves a protective function to prevent foreign matter such as dust from entering the device and affecting the wire.

[0037] The support foot 3 is connected to the second threaded hole at the bottom of the support column 1 by threading. When the device is deployed for use, the support foot 3 provides stable support. The conical cross-section and the second anti-slip pattern on the surface can increase the friction with the placement plane, making the device more stable when placed, preventing the device from tipping over due to accidental impact or other reasons, and thus protecting the stored wire from damage.

[0038] The above merely describes certain exemplary embodiments of the present application by way of illustration, and it is needless to say that the described embodiments can be modified in various ways without departing from the spirit and scope of the present application for those skilled in the art. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the present application.
