Description

Technical Field

[0001] The utility model relates to the technical field of springs, in particular to a non-deformable special-shaped spring. Background Art

[0002] A special-shaped spring is a spring of a special shape, and its main function is to provide elastic support and vibration control in a mechanical system. It consists of a spring body, a spring material, and an end connection. The spring body is usually designed to be cylindrical, conical, or corrugated to meet different application requirements and space constraints. The spring material generally uses spring steel or high-strength alloy to ensure its long-term stable elastic properties and durability. The end connection methods are diverse, which can be spring eye connection, hook connection, or a customized special connection method, which is selected according to installation and functional requirements; such as a non-deformable special-shaped spring disclosed in the authorization announcement number CN215487362U, including a support cotton, a blocking rod is provided at the side wall of the support cotton, and a clamping mechanism is connected through the outer wall of the support cotton, and the inside of the clamping mechanism includes a movable column, and the movable column is connected through the inner wall of the support cotton, and a special-shaped wire is connected through the inner wall of the special-shaped wire, and a U-shaped rod is connected through the middle of the inner wall of the special-shaped wire, and a triangular block is connected through the middle of the side wall of the U-shaped rod. The outer wall of the U-shaped rod is squeezed against the side wall of the triangular block. Since the side wall of the triangular block is triangular in shape, it can be rotated outward to lie on the inner wall of the movable column. When the bending force on the upper and lower ends of the elastic spring disappears, the upper and lower side walls of the elastic spring become shorter and their width increases. However, during the collapse of the spring body in this technical solution, if there is no external guide to support the spring, the spring body itself is prone to deflection and distortion, and does not move in the radial straight line direction. At this time, the special-shaped spring may be difficult to provide the expected elastic support or vibration control, thereby affecting the overall performance and stability of the mechanical system. Utility Model Content

[0003] The utility model aims to provide a special-shaped spring which is not easy to deform. The special-shaped spring is composed of a spiral equidistant spring and a tapered spring with a variable diameter. The top end of the tapered spring is integrally formed with a vertical guide rod extending downward in the direction of the central axis of the spring. The vertical guide rod enables the spiral equidistant spring and the tapered spring to stably extend and retract on a radial straight line, so as to solve the problems raised in the above-mentioned background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a special-shaped spring that is not easy to deform, comprising a chassis and a special-shaped spring installed on the top of the chassis, the special-shaped spring consisting of a helical equidistant spring and a conical spring connected in sequence at the head and tail ends, an L-shaped double-rod frame installed on the top of the conical spring, and the tail end of the L-shaped double-rod frame extends downwardly and obliquely toward the central axis of the helical equidistant spring and the conical spring and is integrally formed with a diagonal tie rod, a vertical guide rod colinear with the central axis of the helical equidistant spring and the conical spring is installed on the bottom end of the diagonal tie rod, a support column is installed at the center position of the top of the chassis, and the bottom end of the vertical guide rod extends to the interior of the support column and slidably cooperates with the support column.

[0005] Preferably, a plurality of equally spaced arc-shaped hollow portions are provided at the edge of the chassis surface.

[0006] Preferably, a front convex column is integrally formed at the tail end of the conical spring, and the top end of the front convex column is fixedly connected to the head end of the L-shaped double-rod frame.

[0007] Preferably, the pitch of the helical equidistant spring is 10 mm to 40 mm, and the number of turns of the helical equidistant spring 2 is 5 to 8 turns.

[0008] Preferably, the pitch of the conical spring is 10 mm to 40 mm, the number of turns of the conical spring is 5 to 8 turns, and the taper angle of the conical spring is 15 degrees to 20 degrees.

[0009] Preferably, a cylindrical cavity having an outer diameter equal to that of the vertical guide rod is provided inside the support column.

[0010] Compared with the prior art, the beneficial effect of the utility model is that the special-shaped spring which is not easy to deform is provided with a vertical guide rod and an L-shaped double rod frame and other structures which cooperate with each other. The vertical guide rod and the support column guide the spring to maintain radial linear motion during compression and extension. Therefore, without the need for an external guide structure, the spiral equidistant spring and the conical spring can be effectively prevented from swinging, twisting or rotating during movement, thereby ensuring that their radial telescopic movement is consistent with the design requirements of the equipment. This can effectively reduce the generation of load vibration and noise in high-frequency vibration or high-speed operation environments, thereby improving the stability and reliability of the system.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-5 The utility model provides an embodiment: a non-deformable special-shaped spring, comprising a chassis 1 and a special-shaped spring installed on the top of the chassis 1, the special-shaped spring is composed of a spiral equidistant spring 2 and a conical spring 3 connected in sequence at the head and tail ends, the cross-sectional shape of the spiral equidistant spring 2 and the conical spring 3 is a regular hexagon, and the regular hexagonal cross-sectional shape has a larger area and a higher sectional inertia moment than a circular cross-sectional shape, so that the spiral equidistant spring 2 and the conical spring 3 have higher strength and stiffness when bearing loads, and can better resist deformation and damage;

[0019] An L-shaped double-rod frame 4 is installed at the top of the conical spring 3, and the tail end of the L-shaped double-rod frame 4 extends downwardly in an inclined manner toward the central axis of the spiral equidistant spring 2 and the conical spring 3 and is integrally formed with a diagonal tie rod 5. A vertical guide rod 6 colinear with the central axis of the spiral equidistant spring 2 and the conical spring 3 is installed at the bottom end of the diagonal tie rod 5. Through the connection between the L-shaped double-rod frame 4 and the diagonal tie rod 5, space can be effectively utilized to achieve a compact assembly structure. A support column 7 is installed at the center position of the top of the chassis 1, and the bottom end of the vertical guide rod 6 extends to the inside of the support column 7 and slidably cooperates with the support column 7.

[0020] The L-shaped double-rod frame 4 and the vertical guide rod 6 are connected by the inclined tie rod 5, so that the action pressure generated by the L-shaped double-rod frame 4 is transmitted to the vertical guide rod 6 through the inclined tie rod 5, reducing the vibration and lateral displacement generated by the spiral equidistant spring 2 and the conical spring 3 when subjected to external loads, ensuring that the spring can stably bear and transmit the load;

[0021] A plurality of equally spaced arc-shaped hollow portions 101 are provided at the edge of the surface of the chassis 1;

[0022] The tail end of the conical spring 3 is integrally formed with a front convex column 301, and the top end of the front convex column 301 is fixedly connected to the head end of the L-shaped double rod frame 4;

[0023] The pitch of the helical equidistant spring 2 is 10 mm to 40 mm, the number of turns of the helical equidistant spring 2 is 5 to 8 turns, the pitch of the conical spring 3 is 10 mm to 40 mm, the number of turns of the conical spring 3 is 5 to 8 turns, and the taper angle of the conical spring 3 is 15 degrees to 20 degrees;

[0024] The conical spring 3 can provide a more linear elastic response and a wider working range. The helical equidistant spring 2 is used to bear larger static loads and vibration shocks. Through the structural design of the helical equidistant spring 2 and the conical spring 3, the special-shaped spring can evenly distribute different types of loads to various parts of the spring, thereby reducing local stress concentration, extending the service life of the spring, and improving its performance.

[0025] A cylindrical cavity 701 with the same outer diameter as the vertical guide rod 6 is arranged inside the support column 7. During the relative sliding of the vertical guide rod 6 and the support column 7, the cylindrical cavity 701 serves as an up and down sliding cavity of the vertical guide rod 6 to ensure the sliding stability of the vertical guide rod 6 and the support column 7.

[0026] When the embodiment of the present application is in use, the staff first installs the chassis 1 at the bottom end of the helical equidistant spring 2 and the L-shaped double-rod frame 4 at the top end of the conical spring 3 to two load ends that can move toward each other, and the load end causes the conical spring 3 and the helical equidistant spring 2 to collapse. During this process, the load connected to the L-shaped double-rod frame 4 can generate an extrusion force on the L-shaped double-rod frame 4, the inclined rod 5 and the conical spring 3, so that the helical equidistant spring 2 and the conical spring 3 collapse toward the chassis 1, and during this process, the vertical guide rod 6 will slide relatively inside the support column 7. The vertical guide rod 6 and the support column 7 guide the spring to maintain radial linear motion during compression and extension, so that without the need for an external guide structure, the helical equidistant spring 2 and the conical spring 3 can be effectively prevented from swinging, twisting or rotating during movement, ensuring that their radial telescopic movement is consistent with the design requirements of the equipment. This can effectively reduce the generation of load vibration and noise in an environment of high-frequency vibration or high-speed operation, thereby improving the stability and reliability of the system.

Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
