Description

Technical Field

[0001] This utility model relates to the field of piston rod technology, specifically to an anti-deformation piston rod. Background Technology

[0002] Piston rods are commonly used connecting and transmission components in mechanical engineering. They are mainly used to connect pistons and connecting rods to transmit power and motion. There are many types of piston rods, each with different characteristics and applications. Selecting the appropriate piston rod type according to specific needs can improve mechanical performance and service life.

[0003] Some piston rods also have some problems, such as: the piston rod is prone to deformation after long-term use, and there is no effective support for the inside of the piston rod, which can easily affect the service life of the piston rod.

[0004] Therefore, we propose an anti-deformation piston rod to improve the above-mentioned problems. Utility Model Content

[0005] The purpose of this invention is to provide a deformation-resistant piston rod to solve the problem mentioned in the background art that the piston rod is not effectively supported internally and is prone to deformation after long-term use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an anti-deformation piston rod, comprising a piston rod body, wherein a threaded rod is fixedly connected to the bottom end of the piston rod body, and an anti-deformation structure for easy support is provided inside the piston rod body;

[0007] The anti-deformation structure includes a reinforcing block, a support frame, and reinforcing rods. The support frame is installed inside the piston rod body. Reinforcing rods are fixedly connected to the left and right sides inside the support frame. A reinforcing block is fixedly connected to the outside of the support frame. A support plate is fixedly connected to the side of the reinforcing block closest to the outside.

[0008] As a further technical solution of this utility model, the support plate is disposed on the inner side wall of the piston rod body, and the reinforcing rods are arranged in an alternating pattern.

[0009] As a further technical solution of this utility model, the support plate and the reinforcing block are respectively provided in six groups, and the reinforcing block is distributed in a ring outside the support frame.

[0010] As a further technical solution of this utility model, a threaded block is fixedly connected to the top end of the piston rod body, a piston body is provided at the top end of the piston rod body, and an installation sleeve is fixedly connected to the bottom end of the piston body. An installation groove is provided inside the installation sleeve.

[0011] As a further technical solution of this utility model, the inside of the mounting groove is machined with internal threads, and the outside of the threaded block is machined with external threads.

[0012] As a further technical solution of this utility model, the mounting sleeve is installed on the outside of the threaded block through the mounting groove, and the piston body is installed on the top of the piston rod body through the mounting sleeve and the threaded block.

[0013] As a further technical solution of this utility model, a protective layer is provided on the outside of the piston rod body, and a wear-resistant coating and a high-temperature resistant coating are provided on the inside of the protective layer.

[0014] As a further technical solution of this utility model, the high-temperature resistant coating is applied to the outside of the piston rod body, and the wear-resistant coating is applied to the outside of the high-temperature resistant coating.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the anti-deformation piston rod not only facilitates the internal support of the piston rod and the installation of the piston body, but also provides surface protection for the piston body;

[0016] (1) By setting a high temperature resistant coating, a support plate, a support frame and a reinforcing rod, the support frame is installed inside the piston rod body. The support plate and reinforcing block on the outer wall of the support frame can support the inside of the piston rod body, thereby supporting the inside of the piston rod body and preventing the piston rod body from bending during use. The reinforcing rod can support the support frame and increase the strength of the support frame. Supporting the inside of the piston rod body can increase the service life of the piston rod body.

[0017] (2) By setting up an installation groove, an installation sleeve and a threaded block, when the piston body needs to be installed, the installation sleeve is put on the outside of the threaded block, and the piston body is rotated. The piston body drives the installation sleeve to rotate outside the threaded block. Since the internal thread inside the installation groove and the external thread outside the threaded block cooperate with each other, the rotation of the piston body can install the installation sleeve on the outside of the threaded block. Using the threaded block and the installation groove to install the piston body can improve the installation efficiency.

[0018] (3) By setting a protective layer, a wear-resistant coating and a high-temperature resistant coating, the high-temperature resistant coating is applied to the outside of the piston rod body. In some special environments, the piston rod body may need to work under high temperature conditions. The high-temperature resistant coating can remain stable under high temperature conditions and prevent the high-temperature resistant coating from being damaged due to excessive temperature. The wear-resistant coating can improve the wear resistance and corrosion resistance of the piston rod body surface, thereby increasing the service life of the piston rod body.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4 The present invention provides an embodiment of an anti-deformation piston rod, comprising a piston rod body 1, a threaded rod 6 fixedly connected to the bottom end of the piston rod body 1, and an anti-deformation structure for easy support provided inside the piston rod body 1;

[0026] The anti-deformation structure includes a reinforcing block 11, a support frame 12, and a reinforcing rod 13. The piston rod body 1 has a support frame 12 inside, and the left and right sides inside the support frame 12 are fixedly connected to the reinforcing rod 13. The support frame 12 has a reinforcing block 11 fixedly connected to the outside, and the reinforcing block 11 has a support plate 10 fixedly connected to the side of the reinforcing block 11 closest to the outside.

[0027] The support plate 10 is set on the inner side wall of the piston rod body 1, the reinforcing rods 13 are arranged in an alternating manner, and six sets of reinforcing blocks 11 are respectively provided. The reinforcing blocks 11 are distributed in a ring on the outside of the support frame 12.

[0028] Specifically, such as Figure 2 and Figure 3As shown, the support frame 12 is installed inside the piston rod body 1. The support plate 10 and reinforcing block 11 on the outer wall of the support frame 12 can support the inside of the piston rod body 1, thereby preventing the piston rod body 1 from bending during use. The reinforcing rod 13 can support the support frame 12 and increase its strength. The internal support of the piston rod body 1 can increase the service life of the piston rod body 1.

[0029] A threaded block 5 is fixedly connected to the top end of the piston rod body 1. A piston body 2 is provided at the top end of the piston rod body 1. An installation sleeve 4 is fixedly connected to the bottom end of the piston body 2. An installation groove 3 is provided inside the installation sleeve 4. An internal thread is machined inside the installation groove 3. An external thread is machined outside the threaded block 5. The installation sleeve 4 is installed outside the threaded block 5 through the installation groove 3. The piston body 2 is installed at the top end of the piston rod body 1 through the installation sleeve 4 and the threaded block 5.

[0030] Specifically, such as Figure 1 and Figure 4 As shown, when the piston body 2 needs to be installed, the mounting sleeve 4 is placed on the outside of the threaded block 5. Rotating the piston body 2 causes the mounting sleeve 4 to rotate outside the threaded block 5. Since the internal thread inside the mounting groove 3 and the external thread outside the threaded block 5 cooperate with each other, the rotation of the piston body 2 can install the mounting sleeve 4 outside the threaded block 5. Using the threaded block 5 and the mounting groove 3 to install the piston body 2 can improve the installation efficiency.

[0031] The piston rod body 1 is provided with a protective layer 7 on the outside, and a wear-resistant coating 8 and a high-temperature resistant coating 9 are provided inside the protective layer 7. The high-temperature resistant coating 9 is applied to the outside of the piston rod body 1, and the wear-resistant coating 8 is applied to the outside of the high-temperature resistant coating 9.

[0032] Specifically, such as Figure 2 and Figure 3 As shown, the high-temperature resistant coating 9 is coated on the outside of the piston rod body 1. In some special environments, the piston rod body 1 may need to work under high temperature conditions. The high-temperature resistant coating 9 can remain stable under high temperature conditions, preventing the high-temperature resistant coating 9 from being damaged due to excessive temperature. The wear-resistant coating 8 can improve the wear resistance and corrosion resistance of the piston rod body 1 surface, thereby increasing the service life of the piston rod body 1.

[0033] Working principle: In use, the support frame 12 is installed inside the piston rod body 1. The support plate 10 and reinforcing block 11 on the outer wall of the support frame 12 can support the inside of the piston rod body 1, thus preventing the piston rod body 1 from bending during use. The reinforcing rod 13 can support the support frame 12 and increase its strength. The internal support of the piston rod body 1 can increase the service life of the piston rod body 1. When the piston body 2 needs to be installed, the mounting sleeve 4 is put on the outside of the threaded block 5. Rotating the piston body 2 causes the mounting sleeve 4 to move outside the threaded block 5. The piston body 2 rotates, and because the internal thread inside the mounting groove 3 and the external thread outside the threaded block 5 cooperate with each other, the piston body 2 can rotate so that the mounting sleeve 4 can be installed on the outside of the threaded block 5. Using the threaded block 5 and the mounting groove 3 to install the piston body 2 can improve the installation efficiency. The high temperature resistant coating 9 is coated on the outside of the piston rod body 1. In some special environments, the piston rod body 1 may need to work under high temperature conditions. The high temperature resistant coating 9 can remain stable under high temperature conditions and prevent the high temperature resistant coating 9 from being damaged due to excessive temperature. The wear-resistant coating 8 can improve the wear resistance and corrosion resistance of the surface of the piston rod body 1, thereby increasing the service life of the piston rod body 1.
