Although such a setting allows the scaffolding to have two usage states, there are defects, which are mainly reflected in the support seat that adjusts the use height by an electric telescopic rod. The electric telescopic rod is mainly based on the process of converting the rotational motion of the motor into linear motion, so it needs to be connected to electricity at the construction site. This results in the scaffolding requiring prior conditions when in use, and it cannot be used in an environment without power supply. At the same time, there is a risk of motor failure, so it cannot be used when a failure occurs. Utility Model Content

The principle of the utility model is that the climbing frame body 1 has two use states: stop state and moving state. When in the stop state, the inclination angle between the first swing arm 5, the second swing arm 6 and the first support rod 3, the second support rod 4 needs to be less than 90°, so that the universal wheel cannot contact the ground, and the first support rod 3, the second support rod 4 is in contact with the ground; when in the moving state, the inclination angle between the first swing arm 5, the second swing arm 6 and the first support rod 3, the second support rod 4 needs to be equal to 90°, and the combination of the locking member 8 and the locked member 7 maintains the angle, so that the universal wheel contacts the ground, and the first column 3, the second column 4 cannot contact the ground, and it is easy to operate, only need to step on the second swing arm 6 (moving state) or lift the first swing arm 5 (stop state) by foot, compared with the traditional method that needs to rely on driving components such as electric telescopic rods, it is more convenient and has low cost of use, and also makes up for the defect that the driving components need to be connected to electricity and cannot be used after a failure.

[0020] The first swing rod 5 is swingably connected to the first support rod 3 through a hinge structure, and has a locking base surface 51 located at the top, a first mounting base surface 52 located at the outer end, and a first horizontal positioning base surface 53 located at the bottom. The locking base surface 51 contacts the second swing rod 6 when the locked member 7 and the locking member 8 are combined. The first mounting base surface 52 is used to set the locked member 7. The first horizontal positioning base surface 53 is used to set the universal wheel and can be used as a reference surface for setting the universal wheel position of the second swing rod 6. The first swing rod 5 is rectangular in configuration, so that the locking base surface 51, the first mounting base surface 52, and the first horizontal positioning base surface 53 are all planes. The plane is not only convenient for setting the locked member 7 and the hinge structure, but also does not have a contact gap when contacting the second swing rod 6, that is, the contact area is large. The first mounting base surface 52 is located at the outer end to facilitate operators to observe the combination of the locked member 7 and the locking member 8. The first horizontal positioning base surface 53 serves as a reference surface to keep the universal wheel on the second swing rod 6 and the universal wheel on the first swing rod 5 at the same level.

[0021] The second swing rod 6 is swingably connected to the second support rod 4 through a hinge structure, and has a locking mating surface 61 located at the bottom and a second mounting base surface 62 located at the outer end. The locking mating surface 61 contacts the locking base surface 51 after the locking element 8 and the locked element 7 are combined, and is provided with a downwardly extending protrusion 51-a. The protrusion 51-a has a second horizontal positioning base surface 51-a1 maintained at the same level as the first horizontal positioning base surface 53. The second horizontal positioning base surface 51-a1 is used to set the universal wheel, and the second mounting base surface 62 is used to set the locking element 8. The configuration and function of the second mounting rod 6 are consistent with those of the first mounting rod 5. The only difference between the two is that the length of the second mounting rod 6 is longer than that of the first mounting rod 5. Since the second mounting rod 6 is The mounting rod 6 is located above the first mounting rod 5, so the height difference is compensated by the protrusion 51-a, so that the second horizontal positioning base surface 51-a1 and the first horizontal positioning base surface 53 are maintained at the same level, so that the universal wheels installed on the corresponding positioning base surfaces can also be maintained at the same level, so that when the climbing frame body 1 is in a moving state, each universal wheel can maintain contact with the ground, and at the same time, the locking mating surface 61 and the locking base surface 51 are both flat, so that when the climbing frame body 1 is in a working state, the first swing rod 5 and the second swing rod 6 can be superimposed together, so that the first support rod 3 and the second support rod 4 are stably supported on the ground, and the second mounting base surface 62 is located at the outer end to facilitate the operator to observe the combination of the locked component 7 and the locking component 8.

[0022] The fourth assembly base surface 61-a is located at the front end of the second mounting rod 61 and is used to set the lock 8, which makes it convenient for the operator to observe the combination of the locked part 7 and the lock 8. The locking mating surface 61-c is located at the upper end of the second mounting rod 61 and is used to set the hinge structure, and the combination of the locked part 7 and the lock 8 is in contact with the locking contact surface 51-b. The fifth assembly base surface 61-b is located at the lower end of the second mounting rod 61 and is used to set the extension rod 61-b1. The extension rod 61-b1 is used to set the universal wheel, and the horizontal position of the universal wheel of the second wheel frame 6 can be consistent with the horizontal position of the universal wheel of the first wheel frame 5, so that there will be no unevenness when the universal wheel contacts the ground.

[0023] The locked member 7 is configured as a column with a length, and the locking member 8 is configured as a sheet with a thickness, which is axially connected to the shaft member 9 arranged on the second mounting base surface 62, and the lower end has an extension sheet 81 extending toward the locked member 7, and a step-shaped snap-in structure 81-a is obtained through the extension sheet 81, and the snap-in structure 81-a is snap-fitted with the locked member 7. Such a configuration enables the locked member 7 and the locking member 8 to be matched in a snap-fit ​​manner, that is, the combination of the snap-in structure 10 and the locked member 7 is utilized, and the locked member 7 also exists as a preventing component on the rotation path of the locking member 8, that is, the locked member 7 and the locking member 8 are prevented from separating after the combination by limiting the rotation amplitude of the locking member 8, so that the inclination angles between the first swing arm 5 and the first support rod 3, and the second swing arm 6 and the second support 4 are maintained at 90°, and the universal wheel is kept in contact with the ground at all times.

[0024] An inclined surface 10 is provided between the extension piece 81 and the locking piece 8. The inclined surface 10 plays a guiding role, that is, when the second swing rod 6 swings downward, the locking piece 8 will also swing downward, and because the first swing rod 5 is located below the second swing rod 6, it also drives the first swing rod 5 to swing downward. When following the downward swing, the locking piece 8 first contacts the locked piece 7 through the inclined surface 10, and generates a squeezing force when contacting. The squeezing force allows the locking piece 8 to rotate along the inclined trajectory of the inclined surface 10, so that the clamping structure 81-a is moved to the bottom of the locked piece 7 and combined with the locked piece 7.

[0025] A first connecting column 20 is provided on one side of the shaft 9 of the second mounting base surface 62, and a second connecting column 30 is provided on the locking member 8, and a tension spring 40 is provided between the first connecting column 20 and the second connecting column 30. Such a configuration enables the locking member 8 to have the ability to self-lock when the second swing rod 6 swings toward the positioning direction, that is, the tension spring 40 can be compressed and deformed when the locking member 8 is squeezed by the locked member 7, and the tension spring 40 is reset after the locking member 8 is separated from the extension piece 81, so that the locking member 8 rotates to achieve self-reset, so that the locking member 8 can combine with the locked member 7 by itself, that is, the clamping structure 81-a is clamped and cooperated with the locked member 7. In this process, the operator only needs to apply the downward pressure generated by stepping on the second swing rod 6.

[0026] The upper end of the lock 8 has a bent piece 82 obtained by bending, and a first synchronization rod 50 is arranged between the two bent pieces 82. Such an arrangement enables the two locks 8 to swing synchronously, avoiding the tediousness of operating one by one, thereby improving the convenience of use.

[0027] A second synchronization rod 60 is provided between the two first swing rods 5 and between the two second swing rods 6. Such a configuration enables the two first swing rods 5 and the two second swing rods 6 to swing synchronously, avoiding the tediousness of one-by-one operation, thereby improving the convenience of use.

[0028] Although the present invention has been shown and described with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein within the scope of the claims.
