Pin is inserted into connection elongated hole, and the upper and lower adjustable inserting for making guiding vertical rod be formed in axial direction with guide thimble part connects
Connect.
Preferably：Lower position positioned at annular relief on base is provided with multiple connecting ribs, multiple dowels
Plate is uniform along the circumferencial direction of guide thimble part.
The utility model has the advantages and positive effects that：
Using this hold-down gear, after to holddown spring pre-pressing, with the size of thrust, holddown spring can be free
Change decrement, with the compression or elongation of holddown spring, contact roller support member will drive contact roller and spring to move together,
Automatically adjusting for compacted position is realized, contact roller is tightly pressed at all the time on the transmission chain or conveyer belt being compacted, so,
Hold-down gear will automatically adjust compaction degree with the tensioning of driving chain or transmission belt is compacted with lax, it is not necessary to which equipment is stopped
Only run, so as to improve the run time of equipment and improve the operating efficiency of equipment.

Specific embodiment
For the content of the invention of the present utility model, feature and effect can be further appreciated that, following examples are hereby enumerated, and coordinate
Accompanying drawing describes in detail as follows：
Refer to Fig. 1-5, for driving chain or the automatic adjustable hold-down gear of transmission belt, mainly include contact roller 1,
Contact roller support member 2 and base 3.For contact roller, when this hold-down gear is compressed for driving chain, contact roller is preferred
Using the chain sprocket structure that can form cooperation, and when this hold-down gear is compressed for driving belt, contact roller uses common light
Wheel construction.
The contact roller support member is made up of guiding vertical rod 2-2 two parts of U-shaped support 2-1 and the U-shaped support base of connection.
Wheel shaft 2-3 is installed on two sides of U-shaped support, the contact roller is supported on wheel shaft by rotating connectors such as bearings
On, with wheel shaft formation turnable connection along the circumferential direction.The outer surface of contact roller forms pressure with driving chain or transmission belt
Close contact.
The base mainly includes fixed bottom parts 3-1 and the fairlead pipe portion being vertically fixed on bottom parts
Divide 3-2.The bottom parts are connected by bolt part with the support of equipment.Near the position at middle part on the guide thimble part
Annular relief 3-2-1 is installed.The guide thimble part forms inserting and is connected with the guiding upright part, in fairlead
Be set with holddown spring 4 outside tube portion, the two ends of holddown spring respectively with convex annular on the bottom surface of U-shaped cradle portion and guide thimble
