The "in one embodiment" appearing in different places in the specification does not mean the same embodiment, nor is it an embodiment that is independent of or mutually exclusive with other embodiments.
[0020] Embodiment one:
[0021] Please refer to Figure 1 As shown in the figure, the utility model provides a trampoline quick folding locking device, including trampoline main part 1, the outside of trampoline main part 1 is equipped with steel ring 2 through tension spring, steel ring 2 is composed of two parts, and the connecting part of steel ring 2 is welded with fixed frame 3, fixed frame 3 is composed of two parts, the left and right sides of steel ring 2 are welded with left fixed plate 12 and right fixed plate 13 respectively, the top of right fixed plate 13 is installed with the clamping lug 14, and the inside of left fixed plate 12 is provided with the positioning slot 5 for the installation of clamping lug 14.
[0022] The utility model discloses the application of left fixed plate 12 and right fixed plate 13, when folding and storing the trampoline, the clamping lug 14 connected to the surface of right fixed plate 13 is clamped into the inside of clamping slot 15 to complete the reinforcement of the folding part, avoid being influenced by the inside tension spring and opening by itself, in addition, the internal structure of fixed frame 3 at the connecting part of steel ring 2 can also be split to fold the trampoline and reduce the occupation of ground space.
[0023] Embodiment two:
[0024] On the basis of embodiment one, the utility model discloses as Figure 4 The left side of fixed frame 3 inner chamber is fixedly installed with positioning seat 4, the inside of positioning seat 4 is vertically provided with clamping slot 15, the inside of clamping slot 15 is vertically inserted with positioning card frame 8, and the right end of positioning card frame 8 is welded with adjusting plate 6.
[0025] The technical scheme as Figure 1 Positioning card frame 8 and positioning seat 4 cooperate to connect and assemble the two parts of fixed frame 3, and can reinforce the connecting part of the trampoline to ensure the normal use of the trampoline.
[0026] Secondly, in the technical scheme, high elastic tensile spring 7 is welded on the front and rear sides of the bottom of adjusting plate 6, the lower end of high elastic tensile spring 7 is connected with the bottom of the inner chamber of fixed frame 3, right side fixed installation has the tensile plate 9 on the top of adjusting plate 6, and the upper end of tensile plate 9 extends to the outside of fixed frame 3, the protective cover 10 is clamped and installed on the upper surface of steel ring 2 outside fixed frame 3, and the protective cover 10 is wholly covered outside fixed frame 3 and tensile plate 9.
[0027] It adopts asFigure 1 The technical solution shown has a high-elasticity tension spring 7 with strong tensile properties, which can drive the adjustment plate 6 to remain stable inside the fixed frame 3. It will not be affected by violent vibration during the use of the trampoline, and can prevent the positioning bracket 8 from moving out of the positioning seat 4. The external protective cover 10 can protect the overall structure and prevent children from touching it and getting injured.
[0028] Example 3:
[0029] This utility model is as follows Figures 1-4 As shown, a threaded mounting block 11 is fixedly installed at the bottom of the fixed frame 3, and the support leg at the bottom of the threaded mounting block 11 is threaded with its internal parts; a vertically arranged guide groove is provided on the right side of the inner cavity of the fixed frame 3, and the inside of the guide groove is connected to the right end of the adjustment plate 6 through a guide slider.
[0030] Using the above technical solution, the assembled threaded mounting block 11 can rotate and move together with the folded fixed frame 3, and can also install support legs inside without affecting the support of the trampoline bottom. The guide groove inside the fixed frame 3 cooperates with the guide slider to limit one end of the adjustment plate 6, ensuring balance when moving up and down inside the fixed frame 3.
[0031] The working principle of this utility model is as follows: When folding the trampoline, the protective cover 10 is first removed, and the adjusting plate 6 is moved upward by the stretching plate 9, so that the left end of the positioning bracket 8 is moved out of the positioning groove 5 and then fixed. Then the trampoline can be folded symmetrically. Since the fixing frame 3 is a separate design, it will not affect the folding. When folding, the right-side locking protrusion 14 needs to be inserted into the locking groove 15 inside the left fixing plate 12. In addition, the insertion plate is inserted into the reserved groove on the surface of the locking protrusion 14 to complete the reinforcement. This structure can prevent the trampoline from opening on its own after folding, so as to reduce the occupation of ground space.
