Embodiment

Understand for technical characteristics of the present utility model, purpose and effect being had more clearly, now contrast description of drawings embodiment of the present utility model.

As Fig. 1～shown in Figure 4, a kind of spring clamp 1, the handle 12 that described spring clamp 1 includes a pedestal 11 and articulates with this pedestal 11, be provided with a connecting rod 13 that articulates with described handle 12 rear portions between described pedestal 11 and handle 12, described connecting rod 13 front portions are provided with a coupler body that can move forward and backward 14.Described spring clamp 1 also includes a plate 2, and described connecting plate 2 is provided with the hook portion 21 that can be established by described coupler body 14 hooks.In the present embodiment, described pedestal 11 is fixedly connected on the one first object (not shown); Described connecting plate 2 is fixedly installed on the position of relative pedestal 11 on the one second object (not shown) of desiring to connect with first object.Thus, can two articles be bound up apace by described spring clamp.

In a better embodiment of the present utility model, as Fig. 1, shown in Figure 4, described pedestal 11 is made of the lug 112 of a substrate 111 and both sides thereof, described handle 12 is a tabular component, this tabular component rear end is provided with extension part 121 to down either side, the lug 112 of described correspondence and extension part 121 articulate (adopting as shown in Figure 3, two rivets 15 in the present embodiment) by rivet 15 respectively.

As Fig. 5, shown in Figure 6, in a better embodiment of the present utility model, described connecting rod 13 is a U-shaped structure, and its opening end correspondence is provided with two through holes 131, is worn by a bearing pin 16 on the extension part 121 that is connected in described handle 12 rear ends (as shown in Figure 4); The closed end of described U-shaped structure is provided with a screw (not shown), and described coupler body 14 comprises screw rod of being located in the described screw 141 and the clasp joint body 142 of being located at screw rod 141 front portions, also is provided with a lock screw 143 on the described screw rod 141.

Further, as Fig. 1, Fig. 4, shown in Figure 6, described lock screw 143 is positioned at the place ahead of U-shaped structure closed end, between this lock screw 143 and closed end screw, also be provided with a hasp 17, this hasp 17 is set on the described screw rod 141, hasp 17 tops are provided with a flexible clamping portion 171, and this flexible clamping portion 171 is a crotch-shaped; Be provided with a draw-in groove 122 that connects with described flexible clamping portion 171 relative positions on the described handle 12.

Above-mentioned spring clamp 1 in use, at first connecting plate 2 is welded on the side of second object, again pedestal 11 is welded on the opposite side-edge of first object, unclamp lock screw 143, the screw rod 141 of rotation coupler body 14 is to adjust the position of clasp joint body 142 and connecting plate hook portion 21, after clasp joint body 142 hooks connecting plate hook portion 21, lock screw 143 tightened screw rod 141 is fixed in the screw of connecting rod 13; At this moment, handle 12 to pedestal 11 directions pushings, is made the flexible clamping portion 171 of hasp 17 pass the draw-in groove 122 on the handle 12 and is fastened on the edge of draw-in groove 122; Like this, just first object and second object have been linked together apace (as Fig. 7, shown in Figure 8).Because in the utility model, after the spring clamp clamping, pass the draw-in groove 122 on the handle 12 and be fastened on the edge of draw-in groove 122 by the flexible clamping portion 171 of hasp 17, so that handle 12 lockings are lived, therefore, the wedging position accidental release can be prevented, the more firm of spring clamp clamping can be made.

In the time first object will being separated with second object, promote earlier the flexible clamping portion 171 of hasp 17, make itself and the edge disengagement of draw-in groove 122, with handle 12 to opening away from pedestal 11 directions, clasp joint body 142 and connecting plate hook portion 21 are separated, first object can be separated apace with second object.

From the above mentioned, spring clamp of the present utility model has simple in structure, easy to operate, characteristics efficiently, can realize quick connection or separation between two objects.

The above only is the schematic embodiment of the utility model, is not in order to limit scope of the present utility model.Any those skilled in the art, equivalent variations of having done under the prerequisite that does not break away from design of the present utility model and principle and modification all should belong to the scope that the utility model is protected.
