Abstract
The utility model relates to a kind of belt stretchers, belong to technical field of mechanical transmission.The belt stretcher includes the hinged belt wheel mounting plate in rack in one end, the other end support tensioning pulley and middle part and one end of tensioning spring hook of the belt wheel mounting plate connect, the other end of the tensioning spring and one end of adjusting rod hook and connect, the shaft of the adjusting rod passes through the adjustment seat gear hole for being fixed on rack, the card slot that there are the gear hole at least two constraint adjusting rods to change tensioning spring length.In this way, pull rod only need to be manually changed in the position of adjusting seat card slot when needing to adjust the rate of tension of driving belt, change tensioning spring in turn draws high length, the adjustment to driving belt rate of tension can be completed without using tool, rapid and convenient is beneficial to guarantee the smooth operation of equipment.
Description
Technical field
The utility model relates to a kind of tensioning apparatus, especially a kind of belt stretcher belongs to mechanical transmissioning technology neck
Domain.
Background technique
Tensioning apparatus is the common component of transmission device in various mechanical equipments.Current tensioning apparatus some can not adjust
Tensioning degree；Though some are adjustable, need to operate comparatively laborious using tool.
Summary of the invention
The purpose of this utility model is that: for the above disadvantage of the existing technology, propose one kind without using tool
It can complete the belt stretcher adjusted to driving belt rate of tension.
In order to reach the goals above, the belt stretcher of the utility model includes that the hinged belt wheel in rack in one end is installed
Plate, the other end support tensioning pulley and middle part and one end of tensioning spring hook of the belt wheel mounting plate connect, the tensioning
The other end of spring and one end of adjusting rod hook and connect, and the shaft of the adjusting rod passes through the adjustment seat gear for being fixed on rack
Hole, the card slot that there are the gear hole at least two constraint adjusting rods to change tensioning spring length.
In this way, when needing to adjust the rate of tension of driving belt, pull rod need to be only manually changed in the position of adjusting seat card slot,
Change tensioning spring in turn draws high length, can complete the adjustment to driving belt rate of tension without using tool, quickly just
Victory is beneficial to guarantee the smooth operation of equipment.
The utility model further improves, and the adjusting rod is in T shape, by the shaft and horizontal handle of vertical cylinder
Hand is constituted.
The utility model further improves, and the adjustment seat is in angle steel shape, by vertical mounting plate and level
Gear plate is constituted.
The utility model further improve is, the gear hole in the middle part of the gear plate have five at card slot, described five
Place's card slot includes the dislocation card slot held position card slot and be distributed in gear hole two sides.
Detailed description of the invention
The utility model will be further described below with reference to the accompanying drawings.

Specific embodiment
Embodiment one
The present embodiment belt stretcher is as depicted in figs. 1 and 2, passes through the hinged belt wheel in rack of spacer 8 including one end
Mounting plate 4, the tensioning pulley 1 that the other end support of the belt wheel mounting plate 4 matches with transmission belt to be tensioned, and the hook in the middle part of it
Hole and one end of tensioning spring 5, which hook, to be connected, and the other end of the tensioning spring 5 and the lower end of adjusting rod 6 hook and connect.
The specific structure of adjusting rod 6 is as shown in Figure 3 and Figure 4, is in T shape, by the shaft 6-2 and horizontal handle of vertical cylinder
Hand 6-1 is constituted, and shaft 6-2 passes through 7 gear hole of adjustment seat for being fixed on rack, specific structure combination Fig. 5 of adjustment seat 7 when assembly
With shown in Fig. 6, in angle steel shape, it is made of vertical mounting plate 7-2 and horizontal gear plate 7-1, the gear in the middle part of gear plate 7-1
Hole has the card slot of constraint adjusting rod 6 change 5 length of tensioning spring at five, in addition to the card slot of the end of one end position, remaining four card slot
For be respectively distributed to gear hole two sides staggered positions dislocation card slot, such gear shift operation is very convenient.
After equipped with corresponding belt gear, when needing to adjust the rate of tension of driving belt, it need to only be stirred with hand
Pull rod changes it in the position of adjusting seat card slot as one sees fit, i.e., changeable tensioning spring draws high length, to realize driving belt
The adjusting of rate of tension, without using tool, rapid and convenient.
