The embodiment of the utility model discloses a length measuring device for a conductive rod.

Referring to fig. 1 and 2, a length measuring device for a conductive rod includes a base 1, and the base 1 is provided with an electronic dial gauge 3. The electronic dial gauge 3 includes a gauge body 31, a connection pipe 32, and a probe 33. The connection tube 32 is fixedly mounted on the watch body 31, and the probe 33 is elastically stretched over the connection tube 32. The elastic expansion and contraction allows the probe 33 to be pressed to retract into the connecting tube 32, and the probe 33 automatically extends out of the connecting tube 32 after the probe 33 is released. The gauge 31 is measured according to the length of the probe 33 contracted in the connection tube 32.

Referring to fig. 1 and 2, two clamping blocks 4 are fixedly mounted on one side wall of the base 1, and clamping grooves 5 in which the connecting pipes 32 are placed are formed in the two clamping blocks 4 facing each other at a time. Both clamping blocks 4 have elasticity, and both clamping blocks 4 are made of plastic or metal with small elasticity.

After the two clamp blocks 4 are spread, the connecting pipe 32 is placed in the two clamp grooves 5. Then the clamping block 4 is loosened, and the connecting pipe 32 is clamped by the clamping block 4 under the action of elastic force, so that the electronic dial indicator 3 is mounted on the base 1. After the electronic dial indicator 3 is powered off, the clamping blocks 4 can be unfolded, then the electronic dial indicator 3 powered off is taken out to be charged, the electronic dial indicator 3 powered on is put into the two clamping blocks 4 again to be clamped, and therefore the situation that the whole length measuring device cannot be used after the electronic dial indicator 3 is powered off is reduced.

Referring to fig. 1 and 2, a bolt 6 is disposed between two clamping blocks 4, through holes 7 through which the bolt 6 passes are formed in both clamping blocks 4, and the positions of the through holes 7 are higher than the positions of the clamping grooves 5. After the two clamping blocks 4 clamp the connecting pipe 32, the bolts 6 are used for screwing after penetrating through the through holes 7, so that the clamping force of the two clamping blocks 4 for clamping the connecting pipe 32 is further improved.

In the embodiment of the utility model, each clamping block 4 is provided with only one clamping groove 5, the conducting rod is tubular, and the wall thickness of the conducting rod is large. The difference in diameter between the different sized conductive rods is typically small, so that for different diameter conductive rods, the probe 33 can be abutted against the end of the conductive rod without inserting the conductive rod.

In another embodiment, each clamping block 4 is provided with at least two clamping grooves 5, the clamping grooves 5 on each clamping block 4 are arranged at intervals along the height direction, and the height of each clamping groove 5 is lower than the height of the through hole 7. By providing a plurality of clip grooves 5, the height of the probe 33 can be easily adjusted. Thereby facilitating the placement of the probe 33 against the ends of different conductive rods.

Referring to fig. 3, a positioning groove 8 for placing a conductive rod is formed on the top side of the base 1, and the positioning groove 8 is disposed along the length direction of the probe 33. When the conducting rod is placed on the base 1, the conducting rod enters the positioning groove 8, so that the conducting rod is aligned with the probe 33 conveniently, and the probe 33 is abutted against the end of the conducting rod conveniently.

The distance between the two opposite side walls of the positioning groove 8 is gradually reduced from the notch of the positioning groove 8 to the bottom of the groove, so that the positioning groove 8 is convenient for the conductive rods with different diameters to enter, and the length measuring device is convenient for measuring the conductive rods with different sizes.

Referring to fig. 3 and 4, a support block 9 is provided on the top side of the base 1, and a slider 10 is fixedly mounted on the bottom side of the support block 9. The base 1 is of a hollow structure, a sliding opening 11 for sliding the sliding block 10 is formed in the bottom of the positioning groove 8, and the sliding opening 11 is communicated with the inside of the base 1. The slide 11 is provided along the length of the probe 33. The probe 33 is directed towards the support block 9, and the slider 10 slides inside the slide opening 11, so that the support block 9 is moved closer to or further away from the probe 33.

Referring to fig. 3 and 4, a stopper 12 is fixedly mounted on one side of the slider 10 away from the supporting block 9, and the stopper 12 abuts against the inner top wall of the base 1. The limiting block 12 is clamped with the inner top wall of the base 1, so that the situation that the sliding block 10 is pulled out from the sliding opening 11 upwards is reduced.

Referring to fig. 3 and 4, the base 1 is provided with a limiting assembly 13, and the limiting assembly 13 includes a nut 131 and a screw 132. The nut 131 is fixedly arranged on the side wall of the base 1 far away from the clamping block 4, and the screw 132 is threaded through the nut 131. The screw 132 also penetrates through the side wall of the base 1 and abuts against the limiting block 12.

By the screw 132 and the nut 131 being engaged, the screw 132 is rotated, thereby adjusting the length of the screw 132 into the inside of the base 1. When the length of the screw 132 extending into the base 1 increases, the screw 132 pushes the limiting block 12 to move towards the clamping block 4, and the limiting block 12 drives the sliding block 10 to slide in the sliding opening 11 and then drives the supporting block 9 to be close to the probe 33. When the length of the screw 132 extending into the base 1 is reduced, the distance between the screw 132 and the stopper 12 is increased, and then the supporting block 9 is directly pushed away from the probe 33. The distance between the supporting block 9 and the probe 33 is adjustable, so that the length measuring device can conveniently detect conductive rods with different sizes.

A positioning block 2 is fixedly arranged on one side of the base 1 close to the probe 33. The conductive rod is placed in the positioning slot 8, after which one end of the conductive rod is aligned with the probe 33 and the other end of the conductive rod is aligned with the positioning block 2. The positioning block 2 is inserted into the conducting rod, so that the condition that the conducting rod rolls on the base 1 is reduced.

The top side of the base 1 is provided with a taking and placing port 14 for the limiting block 12 to enter and exit, the taking and placing port 14 is communicated with the inside of the base 1, and the taking and placing port 14 is communicated with one end, far away from the clamping block 4, of the sliding port 11. When the conducting rods with different diameters are replaced for detection, the positioning blocks 2 with corresponding shapes on the supporting blocks 9 are selected according to the shape and the size of the conducting rods towards one end of the supporting blocks 9. Then the limiting block 12 enters the base 1 from the taking and placing port 14, so that different positioning blocks 2 can be replaced conveniently.

The embodiment of the utility model provides a length measuring device for a conductive rod, which comprises the following implementation principles: according to the shape and the size of the to-be-detected conductive rod towards one end of the supporting block 9, a positioning block 2 with a corresponding shape is selected on the supporting block 9. Then the limiting block 12 enters the base 1 from the taking and placing opening 14, and then the supporting block 9 is pushed to move, and the sliding block 10 enters the sliding opening 11, so that the supporting block 9 is mounted on the base 1.

And then the screw 132 is screwed into the nut 131 to enable the screw 132 to abut against the limiting block 12, so that the supporting block 9 is pushed to be close to the probe 33. When the distance between the probe 33 and the support block 9 is smaller than the standard length of the conductive rod to be detected, the rotation of the screw 132 is stopped. The standard length of the conductive rod is the length of the conductive rod that needs to be produced.

The probe 33 is then pressed to retract inside the connecting tube 32, placing the conductive rod to be inspected inside the positioning groove 8. The conductive rod is then pushed to move toward the supporting block 9, so that the positioning block 2 is inserted into one end of the conductive rod. The condition that the conducting rod rolls on the base 1 is limited through the positioning block 2.

After the positioning block 2 is inserted into one end of the conducting rod, the probe 33 is loosened, and the probe 33 is abutted against one end of the conducting rod far away from the supporting block 9 after extending out of the connecting pipe 32. The length of the conductive rod is displayed by the meter body 31 according to the length of the probe 33 extending out of the connecting pipe 32, so that the difficulty in reading the length of the conductive rod is reduced, and the efficiency in measuring the conductive rod is improved.

The length of the electronic dial indicator 3 measuring the conducting rod has two conditions: one is to initially register in advance to the electronic dial gauge 3 the distance between the support block 9 and the probe 33 when the probe 33 is not retracted in the connection tube 32, after which the gauge body 31 will show the sum of the distance between the support block 9 and the probe 33 not retracted in the connection tube 32 plus the length of the probe 33 retracted in the connection tube 32. The other is that the electronic dial indicator 3 directly displays the length of the retracted connecting tube 32 of the probe 33, and then manually calculates the distance between the supporting block 9 and the probe 33 of the non-retracted connecting tube 32 plus the length of the retracted connecting tube 32 of the probe 33.

The above embodiments are not intended to limit the scope of the present utility model, so: all equivalent changes in structure, shape and principle of the utility model should be covered in the scope of protection of the utility model.
