Detailed implementation manners

[0021] In combination with the drawings and specific embodiments, the present utility model will be further described. It should be understood that these embodiments are only used to illustrate the present utility model and not to limit the scope of the present utility model. In addition, it should be understood that after reading the content taught by the present utility model, those skilled in the art can make various changes or modifications to the present utility model, and these equivalent forms also fall within the scope defined by this application.

[0022] The standard parts used in the present utility model can all be purchased from the market. The special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part all adopt conventional means such as bolts, rivets, welding, and pasting that are mature in the prior art. At the same time, in order to clearly express the connection relationship and working principle between the components, the drawings in the specification are sorted and drawn in the form of a simplified diagram of the mechanism movement, which will not be elaborated here.

[0023] As Figure 1 shown, a fixing clip for a ladder eaves gutter includes a fixed clip body 1. The fixed clip body 1 includes a side fixing bracket 2, a first clamping member 3, and a second clamping member 4. The side fixing bracket 2 is a symmetric structure. The first clamping member 3 is fixedly arranged on both sides of the bottom of the side fixing bracket 2. The second clamping member 4 is arranged at the bottom of the side fixing bracket 2 through bolts. The second clamping member 4 is rotatably connected to the handle 6 through a rotating shaft piece 5. The handle 6 is fixed to the middle of the side fixing bracket 2 through a fixed shaft. A torsion spring 7 is arranged in the middle gap of the handle 6. The second clamping member 4 can move between open and closed relative to the first clamping member 3. One end of the torsion spring has a torsion rod crossbar on the top of the middle gap of the handle, and the other end has a crossbar on the upper part of the first clamping member. The movement of the first clamping member is realized through the torsion spring and the rotating shaft piece. The torsion spring mainly plays the functions of elasticity and reset.

[0024] Specifically, the first pliers 3 and the second pliers 4 extend to the rear of the fixing clamp body, and the second pliers 4 can move between open and closed relative to the first pliers 3, so that the first pliers 3 and the second pliers 4 are farther apart from each other when open than when closed. The first pliers 3 and the second pliers 4 are used to clamp the edge gutter of the building. When the first pliers 3 and the second pliers 4 are moved from the open state to the closed state, the fixing clamp body 1 can be fixed on the edge gutter of the building.

[0025] A release device is provided on the handle 6, which includes a safety lock 8, a trigger 9 and a locking tongue 10, which can releasably cooperate with the shoulder hole 11 on the side fixing frame 2 to releasably lock the handle on the rear end of the side fixing frame 2 and lock the pliers when closed. The handle is operated to connect the first pliers so that when the handle is pivoted and lifted, the first and second pliers are in an open state, and when the handle is swung down to a lower position, close to the first pliers, the first and second pliers are in a closed state.

[0026] It can be seen that Figure 1 As shown, the rotation of the first pliers 3 is achieved by a handle 6, which is fixed around the axis on both sides of the side fixing frame and is easy to reset by a torsion spring. Figure 2 The locking tongue and shoulder hole lock the pliers effectively before the handle is released.

[0027] Specifically, such as Figure 3 As shown, this device is used to stabilize a ladder with horizontal rungs and vertical rails, in which case the ladder is close to a horizontal eave or gutter at the edge of a building. Figure 3 The U-shaped tubular structure shown is the edge of a building (not shown) with a drainage ditch. At the same time, the device includes a first clamp 3 and a second clamp 4. When used, the first clamp 3 and the second clamp 4 are fixed to the horizontal eaves or drainage ditch. The fixing hook is as shown in FIG. Figure 3 As shown, it is suitable for being fixed on the ladder track. When the device is used in the designated use position, it limits the relative movement of the ladder and the fixing clamp body, thereby achieving the effect of fixing the ladder.

[0028] Grooves 12 are symmetrically provided on the front of the side fixing frame 2, and a fixing seat 13 is provided between the symmetrical grooves 12. Sliding seats 15 are provided in the slide grooves 14 on both sides of the fixing seat 13, wherein the sliding seat 15 is a bilaterally symmetrical structure, and fixing grooves 16 are symmetrically provided on the corners of the sliding seat 15. A fixing plate 17 is provided on the fixing groove 16. The fixing plate 17 is triangular in shape, and a fixing hook 18 is provided at the center of the fixing plate 17 and extends to the outside through the fixing seats 13, the sliding seat 15 and the side fixing frame 2 on both sides. The fixing hooks 18 respectively include a right-angle fixing hook 181 and a circular fixing hook 182. A positioning bolt 19 is provided at the bottom of the fixing seat 13, and the positioning bolt 19 passes through the bottom of the sliding seat 15 and is fixed by the adjustment assembly 20.

[0029] Further, the side fixing bracket 2 includes a lower main body portion 21, and the second clamp member 3 is installed on the upper side of the lower main body portion 21.

[0030] Further, a telescopic spring 22 is provided between the fixed seat 13 and the sliding seat 15. The telescopic spring 22 is sleeved on the positioning bolt 19, and the positioning bolt is located in the middle of the sliding seat. The lifting mechanism of the sliding seat is loaded by the telescopic spring, and the sliding seat can adjust its height as the adjusting component rotates.

[0031] Further, the portion of the side fixing bracket 2 where the fixed hook 18 is provided is provided with an inclined hole slot 23. The adjusting component 20 can rotate to raise and lower the fixed seat 13. The sliding seat can be raised or lowered and fixed at the corresponding position, so that the fixed hook can be adjusted up and down to adapt to ladders with different rail widths. The fixed hook can clamp both round-leg ladders and square-leg ladders.

[0032] Further, friction strips are provided at the heads of the first clamp member 3 and the second clamp member 4 to increase the friction between the first clamp member and the second clamp member and the eaves trough of the building edge being clamped.

[0033] Further, the right-angle fixed hook 181 can be used to fix square ladders, and the round fixed hook 182 can be used to fix round ladders. This feature makes the utility model more comprehensive in adapting to the range of ladders.

[0034] For the more detailed operating steps of the preferred embodiment, when the fixing clip body is in the closed position, the first clamp member and the second clamp member are juxtaposed and in contact at the friction strip. The first clamp member and the handle will rotate around their connection points. The first clamp member and the handle form two connection and installation points. The first clamp member and the handle are biased by a torsion spring. Therefore, releasing the handle will cause the first clamp member to open.

[0035] The safety lock inside the trigger body is biased to the main trigger position to prevent accidental operation. The safety lock can prevent the movement of the trigger body. Only by sliding down the safety lock can the trigger be pressed and the locking tongue at its distal end be moved. This structure of moving the locking tongue is a commonly used control structure in the prior art. According to the above operation, the locking tongue disengages from the shoulder hole on the side fixing bracket, so that the first clamp member can be driven by turning the handle. Then the handle rotates through the rotating shaft piece, and the handle can be closed in the shoulder hole again through the locking tongue.

[0036] According to the above steps, further turning the handle forces the rotating shaft piece to move downward and press against the first clamp member. This force causes the first clamp member to rotate, and then the first clamp member and the second clamp member can clamp the drainage ditch at the building edge. The adjusting component can drive the sliding seat to rise or fall. The telescopic spring can make the sliding seat rise as the adjusting component rises. Its movement mode is obvious from the drawings and the foregoing description and is self-evident in any case.

[0037] Although the described and illustrated apparatus is highly effective in achieving the objects of the invention, it is to be understood that the described embodiments are merely exemplary and that there may be many construction details and design modifications that will be obvious to those skilled in the art without departing from the broad scope and spirit of the invention.
