Abstract
The utility model aims at providing a spiral spring easily connected. Multiple springs can be connected so as to change the overall length of the springs, and therefore the application range of the springs is enlarged. The spiral spring easily connected is structurally characterized in that a top plate is fixed at the top end of the spiral spring, and a bottom plate is welded and fixed to the bottom end of the spiral spring, and threaded through holes which are corresponding in position are formed in the top plate and the bottom plate. When the spiral spring easily connected is used, two or more spiral springs can be stacked, a bolt is used for penetrating through the threaded through holes to connect and fix top plates with base plates which are adjacent, and therefore the two or more spiral springs are connected mutually and the length of the springs is changed. Spiral springs with a certain length do not need to be customized according to a specific application occasion, cost is saved, and a period is shortened.
Description
Technical field
The utility model belongs to field of mechanical technique, specially refers to a kind of helical spring.
Background technique
Spring is a kind of mechanical parts that utilize elasticity to carry out work, in order to motion, the mitigation of controlling parts, impacts or shakes, stores up the size of energy, measuring force etc., is widely used in machine, instrument.Traditional helical spring has a variety of length specifications, uses the spring of different length according to different occasions.But in some occasion, just be difficult to search out the spring of appropriate length, can only customize, increased cost and cycle.
The model utility content
The purpose of this utility model is the helical spring that proposes a kind of easy connection, by a plurality of springs being coupled together to change the entire length of spring, thereby increases its Applicable scope.
The helical spring structure of easy connection of the present utility model is as follows: helical spring top is welded with top board, and bottom is welded with base plate, and described top board and base plate are provided with tapped through hole corresponding to position.
In use, two or more helical springs can be gathered into folds, and utilize bolt to pass tapped through hole, adjacent top board and base plate are connected and fixed, thereby two or more helical springs are interconnected, change the length of spring.So just, without the helical spring according to concrete application customization given length, saved cost, and shortened the cycle.
Further, described top board and base plate are circle, and described tapped through hole has three at least, and are uniformly distributed on top board and base plate.Can guarantee that so upper and lower helical spring is on the same axis, be unlikely to tilt.
The helical spring structure of easy connection of the present utility model is simple, convenient to be made, and the mode that can connect by a plurality of springs changes length, applied widely.
The accompanying drawing explanation
Fig. 1 is the helical spring structural representation of easy connection of the embodiment 1.
Fig. 2 is the distribution schematic diagram of tapped through hole in embodiment 1.
Fig. 3 is two structural representations that helical spring connects in embodiment 1.
Embodiment
Below contrast accompanying drawing, by the description to embodiment, embodiment of the present utility model is described in further detail as the effect of the mutual alignment between the shape of each related member, structure, each several part and annexation, each several part and working principle etc.
Embodiment 1:
As shown in Figure 1, 2, the structure of the helical spring 1 of the easy connection of the present embodiment is as follows: the top of helical spring 1 is welded with top board 2, and bottom is welded with base plate 3, and described top board 2 and base plate 3 are provided with tapped through hole corresponding to position 4.
Top board 2 and base plate 3 are circle, and described tapped through hole 4 is three, and is uniformly distributed on top board 2 and base plate 3.Can guarantee that so upper and lower helical spring is on the same axis, be unlikely to tilt.
As shown in Figure 3, in use, two helical springs 1 can be gathered into folds, and utilize bolt 5 through tapped through hole 4, adjacent top board 2 and base plate 3 are connected and fixed, thereby two helical springs are interconnected, change the length of spring.So just, without the helical spring according to concrete application customization given length, saved cost, and shortened the cycle.
After adopting the helical spring of the present embodiment, just, without the helical spring according to concrete application customization given length, saved cost, and shortened the cycle.
Claims (2)
1. the helical spring easily connected, is characterized in that described helical spring top is welded with top board, and bottom is welded with base plate, and described top board and base plate are provided with tapped through hole corresponding to position.
