DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] The present utility model provides a Figures 1-4 kind of waterproof and corrosion-resistant coil spring as shown, including a coil spring body 1. One end of the coil spring body 1 is provided with a straight plate 2 for installing the coil spring body 1, and further includes:

[0023] A locking mechanism, which includes a first locking component 3 and a second locking component 4. The first locking component 3 and the second locking component 4 are used to limit the movement of the straight plate 2. The first locking component 3 includes a plug 34, and the second locking component 4 includes a clamping ring 43. The plug 34 and the clamping ring 43 are inserted and connected to each other. The top end of the plug 34 and the bottom end of the clamping ring 43 are respectively provided with a first connecting plate 31 and a second connecting plate 41 for connecting with the straight plate 2. The first connecting plate 31 and the second connecting plate 41 are respectively arranged at the top end and the bottom end of the straight plate 2. The outer wall of the plug 34 is provided with a limiting member for limiting the movement of the plug 34.

[0024] Specifically, one end of the coil spring body 1 is fixedly connected to one end of the straight plate 2. The top end and the bottom end of the other end of the straight plate 2 are respectively fixedly connected to one side of the bottom end of the first connecting plate 31 and one side of the top end of the second connecting plate 41. The other side of the bottom end of the first connecting plate 31 is fixedly connected to a first bending plate 32 for the turning of the plug 34. The other side of the top end of the second connecting plate 41 is fixedly connected to a second bending plate 42 for the turning of the clamping ring 43. The bottom end of the first bending plate 32 is fixedly connected to a connecting strip 33 for connecting with the plug 34. The bottom end of the plug 34 is fixedly connected to the top end of the second bending plate 42.

[0025] Furthermore, the coil spring body 1 and the straight plate 2 constitute an existing stainless steel coil spring, and the straight plate 2 is used to be plugged into the card slot of the mounting column. A slot needs to be opened at the bottom of the mounting column card slot. The slot is a horizontal slot, and the direction of the slot is perpendicular to the card slot. The width of the slot is half the diameter of the mounting column. The number of slots is one, which is used to insert the first connecting plate 31 or the second connecting plate 41. The locking mechanism is made of stainless steel. The first connecting plate 31, the first bending plate 32, the second connecting plate 41, the second bending plate 42 and the limiting strip 35 are all made of thin stainless steel, so that they are easy to bend. The plug block 34 is inserted and connected with the clamping ring 43, so that the straight plate 2, the first connecting plate 31, the first bending plate 32, The second connecting plate 41 and the second bending plate 42 form a rectangular frame, thereby wrapping the outer wall on the side where the slot is opened on the mounting column, so that the rectangular frame cannot be displaced, thereby ensuring the stability of the fixation of the coil spring body 1 and the mounting column. The first connecting plate 31 and the first bending plate 32 are cast as one piece, the second connecting plate 41 and the second bending plate 42 are cast as one piece, the contact portion between the connecting strip 33 and the first bending plate 32 is welded, the contact portion between the connecting strip 33 and the plug block 34 is welded, and the contact portion between the plug slot 44 and the second bending plate 42 is welded. When the first bending plate 32 and the second bending plate 42 are bent, the plug block 34 can be moved to the position of the clamping ring 43.

[0026] Specifically, a plug-in groove 44 for inserting the insertion block 34 is provided on the front side of the clamping ring 43, and a locking groove 45 for inserting the limiting member is provided on the front side of the plug-in groove 44. The vertical cross-section of the plug-in groove 44 is circular, the vertical cross-section of the insertion block 34 is circular, the inner wall of the plug-in groove 44 is a rough surface, the outer wall of the insertion block 34 is a rough surface, and the limiting member includes a limiting strip 35, one end of the limiting strip 35 is fixedly connected to the outer wall of the insertion block 34, and the limiting strip 35 is inserted and connected with the locking groove 45.

[0027] Furthermore, the diameter of the plug-in slot 44 is 1.1 times the diameter of the plug-in block 34, the size of the locking slot 45 is twice the size of the limiting strip 35, two limiting strips 35 are provided, which are respectively provided on both sides of the plug-in block 34, and the limiting strip 35 is provided at one end of the plug-in block 34 away from the connecting strip 33. The limiting strip 35 can be bent. When the plug-in block 34 needs to be inserted into the plug-in slot 44, the limiting strip 35 needs to be bent first, and then the plug-in block 34 is inserted into the plug-in slot 44, and then the bent limiting strip 35 is opened so that the limiting strip 35 is inserted into the locking slot 45 to lock the plug-in block 34 and the snap ring 43, so that the plug-in block 34 cannot be separated from the plug-in slot 44. When the plug-in block 34 and the snap ring 43 need to be separated, because the size of the locking slot 45 is larger than the limiting strip 35, the limiting strip 35 needs to be bent first, and then the plug-in block 34 is moved out of the plug-in slot 44 to complete the unlocking work.

[0028] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
