Abstract
The utility model discloses a compression spring which comprises a spiral body. The spiral body comprises a middle arc raised section. An arc recessed section is arranged between the arc raised section and the two ends of the spiral body. A cylinder section is arranged between the arc recessed section and the two ends of the spiral body. Due to the adoption of the technical scheme, the compression spring is suitable for large-area and high-pressure external load.
Description
Technical field
The utility model relates to a kind of pressure spring.
Background technique
Pressure spring is the helical spring that bears to pressure, it is circular that its used material section mostly is, also useful rectangle and multiply steel are entangled and are rolled, pitches such as spring is generally, the shape of pressure spring has: cylindrical, conical, camber and middle concave and a spot of non-circular etc., and to adapt to the demand under the different operating situation.Between the circle of pressure spring and the circle certain clearance is arranged, spring contraction deformation when being subjected to external load stores energy of deformation.But existing spring shape not too adapts to large size, big pressure external load.
The model utility content
Technical problem to be solved in the utility model just provides a kind of pressure spring that adapts to large size, big pressure external load.
For solving the problems of the technologies described above, the utility model adopts following technological scheme: a kind of pressure spring, comprise the spiral body, it is characterized in that: described spiral body comprises the circular arc raised section at middle part, is provided with the circular arc concave section between described circular arc raised section and spiral body two ends.
As preferably, described circular arc concave section is to being cylindrical section between spiral body two ends.
The utility model is owing to adopted technique scheme, pressure spring can adapt to large size, big pressure external load.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is further described:
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, be the embodiment of a kind of pressure spring of the utility model, comprise spiral body 1, described spiral body comprises the circular arc raised section 11 at middle part, is provided with circular arc concave section 12 between described circular arc raised section and spiral body two ends.It is cylindrical section 13 that described circular arc concave section is arrived between spiral body two ends.
Claims (2)
1. a pressure spring comprises spiral body (1), it is characterized in that: described spiral body (1) comprises the circular arc raised section (11) at middle part, is provided with circular arc concave section (12) between described circular arc raised section (11) and spiral body (1) two ends.
2. pressure spring according to claim 1 is characterized in that: described circular arc concave section (12) is to being cylindrical section (13) between spiral body (1) two ends.
