Description

Technical Field

[0001] The utility model relates to the field of springs, in particular to a spring which is easy to fix. Background Art

[0002] A spring is a mechanical part made of spring steel that has an energy storage function. The spring structure is relatively simple. When installing the spring, some springs only need to be compressed and generally the spring is placed between two plates and fixed by screws and nuts. When it needs to be stretched, some tension springs can be connected by hooks at the upper and lower ends, but they are not suitable for compression. In order to be able to stretch and compress the spring and ensure that the ends are firmly fixed, welding is usually used. After the spring is used for a long time or is subjected to a large force, it is difficult to replace the spring alone, which increases the loss. For this reason, we designed a spring that is easy to fix. Utility Model Content

[0003] In order to solve the technical problem of being able to quickly install and replace a spring, the utility model provides a spring that is easy to fix.

[0004] The utility model is implemented by the following technical scheme: a spring that is easy to fix, comprising a spring and a mounting plate, wherein the upper and lower ends of the spring are both spirally bent inwardly to form an abutment portion, two mounting plates are provided, and a fixed pressure plate is installed on the inward side surface of the two mounting plates, a clamping cavity is formed by a gap between the fixed pressure plate and the mounting plate, the fixed pressure plate is inserted into the inward side surface of the abutment portion, and the fixed pressure plate is in close contact with the surface of the abutment portion.

[0005] As a further improvement of the above scheme, the spiral inner circles of the abutting parts on the upper and lower sides of the spring are respectively designed to be vertically upward and downward to form connecting sections, and the top ends of the connecting sections are bent to form connecting rings with circular structures. The design of the abutting parts enables the upper and lower ends of the spring to have force points, and the connecting rings are provided so that the spring can be directly hung like a tension spring, and the connecting rings also enable the spring to be compressed.

[0006] As a further improvement of the above scheme, the multiple spiral parts of the abutment parts on the upper and lower sides are all on the same horizontal plane, and the abutment parts have elastic deformation capabilities, which facilitates the installation of the abutment parts and the contact with the surface of the mounting part, increases the force-bearing area, and facilitates its compression.

[0007] As a further improvement of the above solution, a circular plug-in hole is opened at the center of the mounting plate, and the connecting section and the connecting ring of the spring extend into the plug-in hole, which facilitates the placement of the connecting section and the connecting ring of the spring;

[0008] The abutment portion of the spring contacts the inner surface of the mounting plate, and the smallest inner circle of the abutment portion is larger than the inner diameter of the plug hole. The abutment portion can be placed on the upper surface of the mounting plate, thereby providing effective support.

[0009] As a further improvement of the above scheme, the mounting plate is formed with mounting screw holes at the front and back, and the mounting screw holes are connected to the plug-in holes. The mounting screw holes are threadedly connected to a hanging rod, and the hanging rod is sleeved on the connecting ring of the spring, which can further fix the connecting ring and improve the connection strength.

[0010] As a further improvement of the above scheme, a fixed arc block is provided at the lower end of the fixed pressure plate, and the fixed arc block is screwed to the mounting plate, and the front half of the fixed pressure plate is integrated with an arc portion, and the size of the arc portion is larger than the outer diameter of the inner circle of the abutment portion, which facilitates the installation and disassembly of the fixed pressure plate, and thus enables quick installation and disassembly of the spring.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. The utility model integrates abutment parts at the upper and lower ends of the spring, and cooperates with a fixed pressure plate arranged on the mounting plate. The fixed pressure plate can be inserted into the gap between the abutment part and the end of the spring, and the abutment part is firmly fixed on the mounting plate, so that the spring can be quickly installed and disassembled;

[0013] 2. A connecting section is also provided on the abutting portion, and the connecting section is bent to form a connecting ring, which can be directly used to hang with the connecting piece, so that the spring can be quickly hung and installed without an installation disk, and the abutting portion with a spiral disk-shaped design increases the force-bearing area and facilitates its compression.

[0019] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0020] Example:

[0021] Please combine Figure 1-Figure 3 A spring that is easy to fix in this embodiment includes a spring 1 and a mounting plate 2. The upper and lower ends of the spring 1 are both spirally bent inward to form an abutment portion 11. Two mounting plates 2 are provided, and a fixed pressure plate 3 is installed on the inner side surface of the two mounting plates 2. A clamping cavity is formed by a gap between the fixed pressure plate 3 and the mounting plate 2. The fixed pressure plate 3 is inserted into the inner side surface of the abutment portion 11, and the fixed pressure plate 3 is in close contact with the surface of the abutment portion 11.

[0022] The spiral inner circles of the abutment parts 11 on the upper and lower sides of the spring 1 are respectively designed to be vertically upward and downward to form connecting sections 12, and the top of the connecting section 12 is bent to form a connecting ring 13 with a circular structure. The design of the abutment part 11 enables the upper and lower ends of the spring 1 to have force points, and the connecting ring 13 is provided so that the spring 1 can be directly hung like a tension spring, and the connecting ring 13 also enables the spring 1 to be compressed.

[0023] The multiple spiral parts of the upper and lower abutment parts 11 are all on the same horizontal plane, and the abutment parts 11 have elastic deformation ability, which is convenient for the installation of the abutment parts 11 and the contact with the surface of the mounting part, increases the force-bearing area, and facilitates its compression.

[0024] A circular plug hole 21 is provided at the center of the mounting plate 2, and the connecting section 12 and the connecting ring 13 of the spring 1 extend into the plug hole 21, so as to facilitate the placement of the connecting section 12 and the connecting ring 13 of the spring 1;

[0025] The abutment portion 11 of the spring 1 contacts the inner surface of the mounting plate 2, and the smallest inner circle of the abutment portion 11 is larger than the inner diameter of the insertion hole 21. The abutment portion 11 can be placed on the upper surface of the mounting plate 2, thereby providing effective support.

[0026] The mounting plate 2 is formed with mounting screw holes 22 at the front and back, and the mounting screw holes 22 are connected to the plug-in holes 21. The mounting screw holes 22 are internally threaded with a hanging rod 4, which is sleeved on the connecting ring 13 of the spring 1, and can further fix the connecting ring 13, thereby improving the connection strength.

[0027] A fixed arc block 32 is provided at the lower end of the fixed pressure plate 3, and the fixed arc block 32 is fixed on the mounting plate 2 by screws, and an arc portion 31 is integrally provided on the front half of the fixed pressure plate 3. The size of the arc portion 31 is larger than the outer diameter of the inner circle of the abutment portion 11, which is convenient for the installation and disassembly of the fixed pressure plate 3, and the spring 1 can be quickly installed and disassembled.

[0028] The implementation principle of a spring that is easy to fix in the embodiment of the present application is as follows: in actual use, firstly, the connecting sections 12 and the connecting ring 13 at the upper and lower ends of the spring 1 are extended into the plug-in holes 21 of the mounting plate 2, and then the hanging rod 4 is screwed into the mounting screw hole 22 and plugged into the connecting ring 13 (the hanging rod 4 is a screw rod). At this time, the initial fixation of the mounting plate 2 and the spring 1 can be completed, and then the fixed pressing plate 3 is plugged into the gap between the abutment portion 11 and the end of the spring 1, and finally the fixed pressing plate 3 is fixed to the mounting plate 2 by screws. At this time, the fixed pressing plate 3 will be pressed against the abutment portion 11, so that it is not easy to deform, so that the spring 1 can be stretched and compressed accordingly;

[0029] By integrally forming the abutment portion 11 at the upper and lower ends of the spring 1, and cooperating with the fixed pressure plate 3 arranged on the mounting plate 2, the fixed pressure plate 3 can be inserted into the gap between the abutment portion 11 and the end of the spring 1, and the abutment portion 11 is firmly fixed on the mounting plate 2, so that the spring 1 can be quickly installed and removed;

[0030] A connecting section 12 is also provided on the abutting portion 11, and the connecting section 12 is bent to form a connecting ring 13. The connecting ring 13 can be directly used to hang with the connecting piece, so that the spring 1 can be quickly hung and installed without the installation disk 2. The abutting portion 11 with a spiral disk-shaped design increases the force-bearing area and facilitates its compression.

[0031] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
