Abstract

The utility model discloses a drop prevention structure for a clamp, which is primarily provided with a seat body; a fixing part is arranged at the top edge of the seat body; a first clamping part and a second clamping part which are formed downward are arranged at the bottom edge of the seat body; the first clamping part is provided with a positioning rod; the second clamping part is provided with a screw hole to thread a bolt which is connected with a handgrip, forming a clamp, and the positioning rod and the bolt can clamp a PC board immersed in electroplating liquid or other object to be processed. After the bolt threads through the screw hole of the second clamping part, a fastener with proper elasticity clamps a threaded spacer segment at a proper position of the bolt, so when the bolt is drawn back by the clamp due to the vibration during the operation, the fastener can retain the screw threads of the second clamping part of the seat body to prevent the drop of the bolt.

Description

The anti-drop structure of anchor clamps
Technical field
The utility model relates to a kind of anti-drop structure of anchor clamps, relates in particular to a kind of anchor clamps that prevent and cause the anchor clamps anti-drop structure of bolt falling because of vibration in operation.
Background technology
Be used for generally that the PC plate is electroplated or for the clamp structure of other objects to be processed of clamping (as luminous plate etc.), usually as shown in Figure 1, be provided with a pedestal 1, below pedestal 1, be provided with to formed first clamping part 11 of lower recess and second clamping part 12, this first clamping part 11 is provided with a positioning rod 111,12 of this second clamping parts are provided with a screw 121, for wearing a bolt 13 that is connected in lever, make PC plate or other object clampings to be processed between backstay 111 and bolt 13.Existing anchor clamps are in plating or other operation process, often need anchor clamps are vibrated, as: when electroplating, the PC plate needs to make medicament evenly be applied in welding hole by vibration, therefore cause bolt 13 often to retreat because of vibration, cause coming off in the plating tank, carve inspection and lock new bolt 13 again so take, not only cause the consume of material, and influence operating efficiency.The applicant in view of this, it adheres to this business experience for many years of being engaged in, and through constantly studying, test, improving, so that make anchor clamps can prevent coming off of bolt, makes its operation more convenient.
Summary of the invention
Main purpose of the present utility model promptly is to provide a kind of anti-drop structure of anchor clamps, with prevent anchor clamps in operation because of vibration causes bolt falling, and then avoid the improper consume of material, improve operating efficiency.
The anti-drop structure of aforesaid anchor clamps, be provided with a pedestal, be provided with fixed part at the pedestal apical margin, the pedestal root edge is provided with to formed first clamping part of lower recess and second clamping part, this first clamping part is provided with a positioning rod, this second clamping part then is provided with a screw, for wearing a bolt that is connected in lever, to constitute anchor clamps, make backstay and bolt be dipped in the PC plate of electroplating liquid medicine for inserting and putting, or other object to be processed, wherein, this bolt has the screw thread spacer that suitable elastic fastener is folded in the bolt appropriate location with one behind the screw that wears second clamping part, thereby when anchor clamps retreat bolt because of the vibration in the operation, be able to prevent coming off of bolt in the screw thread of pedestal second clamping part by fastener backstop.
The anti-drop structure of aforesaid anchor clamps, wherein this is folded in the fastener of the screw thread spacer of bolt appropriate location, for having suitable elastic C shape ring, is beneficial to insert and put operation.
By the anti-drop structure of above-mentioned anchor clamps, the utility model has been realized following useful technique effect: prevented anchor clamps in operation because of vibration causes bolt falling, and then avoid the improper consume of material, improved operating efficiency.

Embodiment
Please consult Fig. 2,3 simultaneously, and cooperation Fig. 4, main as the existing anchor clamps of the utility model, be provided with a pedestal 2, be provided with for the fixed part 21 that is fixed in mechanical means at pedestal 2 apical margins, pedestal 2 root edges are provided with first clamping part 22 and second clamping part 23 of downward formation, this first clamping part 22 is provided with a positioning rod 221,23 of this second clamping parts are provided with a screw 231, are connected in the bolt 24 of lever 241 for wearing one, thereby constitute anchor clamps;
This bolt 24 has the screw thread spacer that suitable elastic fastener 3 is folded in bolt 24 appropriate locations with one behind the screw 231 that wears second clamping part 23, wherein, this fastener 3 is for having suitable elastic C shape ring;
The anchor clamps that constitute by aforementioned components, backstay 221 and bolt 24 by pedestal 2 must be dipped in plating liquid medicine for inserting and putting the PC plate in use, or for the object to be processed that inserts and puts other, thereby when anchor clamps retreat bolt 24 because of the vibration in the operation, be able to by the screw 231 of this fastener 3 backstops, to prevent coming off of bolt 3 in pedestal 2 second clamping parts 23.
Please consult Fig. 4 and Fig. 5 simultaneously, the utility model in use, for the fixed part 21 with pedestal 2 apical margins is fixed on mechanical means, by the backstay 221 of pedestal 2 and the screw-in of bolt 24, be dipped in plating liquid medicine for inserting and putting the PC plate, or be used for different processing operations for the object to be processed that inserts and puts other.With PC plate electroplating activity is example, by making medicament evenly be applied in welding hole by vibration at need, therefore, make bolt 24 often retreat because of vibration, bolt 24 of the present utility model screw thread spacer in position, be gripped with suitable elastic fastener 3, therefore, when bolt 24 often retreats position to this fastener 3 because of vibration, this fastener 3 will backstop in the screw 231 of pedestal 2 second clamping parts 23, make bolt 24 can not continued to retreat, to prevent bolt 24 whole coming off by backstop, avoid the improper consume of material, and then improve efficiency of operation.
In sum, the utility model utilization constitutes the anti-drop structure of anchor clamps for being folded in the fastener of bolt, with prevent anchor clamps in operation because of vibration causes bolt falling, and then avoid the improper consume of material, improved operating efficiency.
