Description

A kind of laser connecting rod

Technical field

The utility model belongs to field of mechanical technique, and in particular to a kind of laser connecting rod.

Background technology

Existing laser fixed link is overall fixed structure, after the installation site fixation of laser, it is impossible to adjust, can only Again laser is installed, the needs of to meet at different moments, so swashing every time in the movement of underworkings driving face Special labor intensive during light device, and installation laser difficulty is big, the time of consumption is long, how efficiently to adjust and fixed sharp Light device position is a urgent problem.

The content of the invention

To solve the above-mentioned problems, the utility model provides a kind of laser connecting rod, the utility model is designed reasonably, Pass through setting.

To reach above-mentioned purpose, a kind of laser connecting rod described in the utility model includes the first strut, described first The adjustable connector of axial location is arranged with bar, the second strut of fixed laser is fixedly connected with connector.

Spring card mat and location nut are also arranged with first strut, up-small and down-big cone is provided with spring card mat Face and the opening through spring card mat axial direction, connector inner side is provided with internal thread and step is raised, is set in location nut There is the external screw thread engaged with the internal thread of connector, the step of connector is raised to connect with the conical surface of spring card mat, connector Bottom surface connects with the upper end of location nut.

Clip and location nut are also arranged with first strut, connector is provided with internal thread, connector and positioning Nut thread connects, and clip is arranged on below location nut, for limiting the position of location nut.

The connector and the second strut are threadedly coupled.

The first strut upper end is provided with screw thread.

The height of first strut is 500mm, and the length of the second strut is 200mm.

Compared with prior art, the utility model at least has technique effect beneficial below, and the utility model is equipped with upper The lower adjustable connector in position, connector outside are fixedly connected with the second strut of fixed laser, pass through adjustable connector Setting, realize the effect for conveniently adjusting fixed laser, greatly saved manpower and time.

Further, by spring card mat, location nut and connector three mutual cooperation or pass through clip, positioning Nut and the mutual cooperation of connector three

Further, adjustable for height function of the connector on the first strut is realized,.

Further, connector and the second strut are threadedly coupled, convenient dismounting.

Further, the first strut upper end is provided with screw thread, convenient to be connected with anchor pole.

Embodiment

The utility model is described in detail with reference to the accompanying drawings and detailed description.

Embodiment 1

Referring to figs. 1 to Fig. 2, a kind of laser connecting rod includes the first strut 1, and 3 He of connector is arranged with the first strut 1 Location nut 5, connector 3 and 5 and first strut 1 of location nut are clearance fit, and location nut 5 is step shaft-like, connection Threaded hole is provided with device 3, the second strut 2 is connected with threaded hole, the second strut 2 and the first strut 1 are mutually perpendicular to, laser It is fixed on the second strut 2,3 lower end of connector is provided with internal thread, and location nut 5 is provided with external screw thread, connector 3 and fixed Position nut 5 is threadedly coupled, and 1 upper end of the first strut is provided with screw thread, which is used to be connected with the threaded hole on anchor pole, easy to incite somebody to action Whole device is installed on below anchor pole.

With reference to Fig. 3, be arranged with spring card mat 4 on the first strut 1, spring card mat 4 by a up-small and down-big taper surface and Cylinder, which connects, to be formed, and the diameter of taper bottom surface is more than the diameter of cylinder, and offers in spring card mat 4 and opened through upper and lower Mouthful, which makes spring card mat 4 have elasticity, and 4 upper end of spring card mat is caught in inside connector 3, and lower end is caught in location nut 5 In endoporus, connector 3 is internally provided with step protrusion, when needing fixed connection device 3 in the position on the first strut 1, twists The tightly screw thread between connector 3 and location nut 5, at this time, the conical surface of spring card mat 4 are raised by the step of the inner side of connector 3 Downwards and the power to central shaft, while by the upward active force of location nut 5, power of the spring card mat 4 in above three direction Act under shed and shrink locking the first strut 1, while limit moving up and down for connector 3 and location nut 5, when needing the company of adjustment When connecing the position of device 3, the screw thread between connector 3 and location nut 5 is unclamped, is then moved up connector 3, at this time spring The no longer stress of card mat 4, also just no longer limits the movement of location nut 5, and connector 3 is moved to target position according to being actually needed Postpone and again fill in 4 upper end of spring card mat in connector 3, then running fix nut 5 is until upper end and the bullet of location nut 5 The lower end of 4 taper surface of spring card mat connects.

Preferably, the height of the first strut 1 is 500mm, and the length of the second strut 2 is 200mm, is ensureing as far as possible big tune While adjusting range, other work are not influenced as far as possible.

Embodiment 2

With reference to Fig. 4, the present embodiment and the difference of embodiment 1 are, remove spring card mat 4, add clip 6, card Hoop 6 is arranged on the lower section of location nut 5, tightening and unclamps fixed or adjusting connector 3 on the first strut by clip 6 Position.

This practicality is installed for laneway laser, and laser is placed on the second strut 2, with second behind the adjustment position of left and right Strut 2 is fixed, thus makes laser accurately direction, has object to block laser in case of in front of, can loosen First strut location nut 5, tightens location nut 5 after adjusting good position up and down, is installed and adjusted laser using this covering device Easily, the substantial amounts of time is saved.
