Detailed Description

The present application is described in further detail below with reference to figures 1-2.

The embodiment of the application discloses strain clamp. Referring to fig. 1 and 2, a strain clamp includes an upper holder 1, a lower holder 2, and a fastening bolt 3 for connecting the upper holder 1 and the lower holder 2, wherein the upper holder 1 and the lower holder 2 are provided with a threaded hole for inserting the fastening bolt 3. The cable between the upper holder 1 and the lower holder 2 is fixed by a fastening bolt 3.

Referring to fig. 1 and 2, a fixing rod 4 is fixedly connected to the upper holder 1, an inserting block 5 is fixedly connected to the other end of the fixing rod 4, a connecting block 6 is connected to one end of the lower holder 2, which is far away from the upper holder 1, and a connecting groove 7 for inserting the inserting block 5 is formed in the connecting block 6. By inserting the insertion block 5 into the connection groove 7, a preliminary fixed connection between the upper holder 1 and the lower holder 2 is achieved. Since the end of the insertion block 5 inserted into the connection groove 7 is the circular arc end 15, when the insertion block 5 needs to be inserted into the connection groove 7, the circular arc end 15 guides the insertion block 5 to align with the connection groove 7 so as to facilitate the insertion of the insertion block 5 into the connection groove 7. And fixedly connected with rubber layer 14 on the inner wall of spread groove 7, because the existence of rubber layer 14, insert piece 5 will extrude rubber layer 14, and rubber layer 14 is because elasticity of self can the reconversion and carry out the centre gripping to inserting piece 5, and because the coefficient of friction on the surface of rubber layer 14 is greater than the coefficient of friction of connecting block 6 inside wall, when inserting piece 5 and inserting in spread groove 7 completely, can also increase the frictional force of spread groove 7 inside wall to inserting piece 5 through rubber layer 14, the stability that the reinforcing inserts piece 5 and is located spread groove 7.

Referring to fig. 1 and 2, a limiting component 8 for limiting the insertion block 5 is further disposed on the connection block 6. Spacing subassembly 8 is including spring 9 and stopper 10, spring 9's one end and stopper 10 fixed connection, and spring 9's the other end and connecting block 6 fixed connection open on inserting piece 5 has first spacing groove 11, and connecting block 6 is last to open has the second spacing groove 12 with spread groove 7 intercommunication. The stopper 10 passes through the second limiting groove 12 and is inserted into the connecting groove 7, and even if the spring 9 is pulled to the limit, the stopper 10 is still located in the second limiting groove 12, so that the stopper 10 can not move out of the second limiting groove 12 towards one end of the connecting block 6, and the staff does not need to adjust the alignment relation between the stopper 10 and the second limiting groove 12. Insert the in-process that piece 5 inserted to spread groove 7 at the staff, insert piece 5 and insert the one end that the piece 7 inserted earlier to spread groove 7 and stopper 10 and contact towards the slope end 13 that the one end of spread groove 7 set up, insert the removal in-process of piece 5, insert piece 5 and contact with slope end 13 earlier to through squeezing slope end 13, drive stopper 10 and remove and make spring 9 stretched towards the direction of keeping away from last holder 1. Until insert the piece 5 and insert in connecting groove 7 completely after, first spacing groove 11 aligns with second spacing groove 12, stopper 10 drives stopper 10 and passes first spacing groove 11 in order to insert to second spacing groove 12 under the effort of spring 9 elasticity, realizes connecting block 6 and the relative fixed connection who inserts piece 5 through stopper 10's effect.

Referring to fig. 1 and 2, a rotating block 16 is fixedly connected to one end of the connecting block 6 facing the lower clamping seat 2, a limiting block 17 integrally connected with the rotating block 16 is arranged at one end of the rotating block 16 far away from the connecting block 6, the size of the limiting block 17 is larger than that of the rotating block 16 and can be deformed, a rotating groove 18 for inserting the rotating block 16 and a limiting groove 19 communicated with the rotating groove 18 are formed in the lower clamping seat 2, and the limiting block 17 penetrates through the rotating groove 18 and is inserted into the limiting groove 19. And one end of the limiting block 17 facing the bottom of the limiting groove 19 is conical, so that the limiting block 17 is easy to deform and insert into the limiting groove 19 when contacting with the lower clamping seat 2. Insert limiting block 17 and have the effect of realizing 16 and lower holder 2 relatively fixed of turning block in limiting groove 19, and turning block 16 rotates to be connected and has the effect of realizing connecting block 6 and lower holder 2's rotation and being connected in turning groove 18 to make things convenient for the staff to adjust the direction of spread groove 7, be convenient for find right suitable position make insert block 5 insert to spread groove 7 in. If the lower holder 2 is not flat on the side away from the upper holder 1 due to the connecting block 6, the restricting block 17 is inclined toward the axial line of the rotating block 16 toward the end of the rotating block 16. The staff can press down holder 2 and draw connecting block 6 towards the direction of keeping away from holder 2 down, through the deformation effect of restriction piece 17, makes restriction piece 17 break away from in 19 so as to reach the effect that connecting block 6 and holder 2 separated down.

The embodiment of the application discloses strain clamp's implementation principle does: when the staff need carry out the relative connection with last holder 1 with holder 2 down, only need will insert piece 5 and remove in the direction spread groove 7, make and insert piece 5 and insert in spread groove 7, and insert piece 5 and insert the back in spread groove 7, stopper 10 passes second spacing groove 12 and realizes strengthening the stability of being connected between last holder 1 and lower holder 2 in order to insert to first spacing groove 11.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
