Detailed Description

The following describes embodiments of the present invention in further detail with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.

In the description of the present invention, "a plurality" means two or more unless otherwise specified; the terms "upper", "lower", "left", "right", "inner", "outer", "front", "rear", "head", "tail", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are merely for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention. In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "connected" and "connected" are to be interpreted broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; may be directly connected or indirectly connected through an intermediate. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

The utility model discloses a fastener of high stability, including lower plate 1 and punch holder 2, punch holder 2 and lower plate 1 are connected through bolt assembly 3, all are provided with storage tank 4 that is used for the holding cable on punch holder 2 and the lower plate 1, in order to increase the utility model discloses an overall structure stability increases the bonding strength between punch holder 2 and the lower plate 1, the utility model discloses make following improvement:

as shown in fig. 1-5, the lower clamp plate 1 is provided with a first boss 5 for limiting the rotation of the upper clamp plate 2, the width of the top of the first boss 5 is the same as that of the bottom of the first boss, and the upper clamp plate 2 is provided with a first groove 6 matching with the first boss 5.

In this embodiment, when punch holder 2 and lower plate 1 cooperation pressed from both sides tight cable, first boss 5 card is gone into in first recess 6, can effectually prevent punch holder 2 and lower plate 1 relative rotation, and the top width of first boss 5 is the same rather than the bottom width, and the clearance between punch holder 2 and the lower plate 1 homoenergetic is when the high range of first boss 5 can make the inseparable cooperation of first boss 5 and first recess 6, great increase the utility model discloses an overall structure stability.

The height of first boss 5 is not less than 20 millimeters, avoids making punch holder 2 and lower plate 1 can not adapt to the phenomenon emergence of thick cable because the highly undersize of first boss 5, increases the utility model discloses an adaptability.

In a preferred embodiment, as shown in fig. 2, the upper clamping plate 2 is provided with a second boss 7 and a second groove 8 matching with the second boss 7 at two ends.

In this embodiment, when the punch holder 2 sets up when a plurality ofly, second boss 7 on one of them punch holder 2 can cooperate with the second recess 8 on the adjacent punch holder 2, further increase the joint strength of punch holder 2 and lower plate 1, even if because the tight cable of clamp is too thick, first boss 5 can not cooperate with first recess 6, under the cooperation of second boss 7 and second recess 8, can restrict and produce relative rotation between punch holder 2 and the lower plate 1, further increase the utility model discloses an overall structure stability.

As shown in fig. 2, the second groove 8 runs through both sides of the upper clamping plate 2, so that there is a height difference between two adjacent upper clamping plates 2, and the installation accuracy of the utility model is increased.

As shown in fig. 1 and 5, the lower clamp plate 1 is provided with a third boss 9 in cooperation with the bolt assembly 3.

In this embodiment, the setting that third boss 9 is relative is in bolt assembly 3's both sides, and bolt assembly 3 is mobilizable as for between two third bosses 9, and two third bosses 9 can restrict bolt assembly 3 rotatory, have increased the utility model discloses convenience during the installation.

Be provided with rib 10 in the storage tank 4, great increase the utility model discloses and the bonding strength between the cable that fastens.

The utility model discloses a theory of operation: the utility model is provided with a first boss 5 with the same width at the top and the bottom on the lower splint 1, and a first groove 6 matched with the first boss 5 is correspondingly arranged on the upper splint 2, the first boss 5 can slide in the first groove 6 to a certain extent, when the fastened cable is thick, the first boss 5 can still be matched with the first groove 6, thereby greatly increasing the stability of the utility model, can effectively avoid the relative rotation between the upper splint 2 and the lower splint 1, increases the stability of the utility model, and the adjacent two upper clamping plates 2 are matched with each other through the second lug bosses 7 and the second grooves 8, so that the combination of the upper clamping plates 2 and the lower clamping plates 1 is more stable, even if the first boss 5 and the first groove 6 are separated, the upper clamping plate 2 and the lower clamping plate 1 can be effectively prevented from rotating relatively under the action of the second boss 7 and the second groove 8.

The embodiments of the present invention have been presented for purposes of illustration and description, and are not intended to be exhaustive or limited to the invention in the form disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art.
