Description

Technical Field

[0001] This utility model relates to the technical field of electric heater fixing mechanisms, specifically an electric heater fixing mechanism that is easy to install. Background Technology

[0002] Electric heaters are a popular type of electric heating equipment internationally. They are used for heating, maintaining, and warming flowing liquid and gaseous media. When the heating medium passes through the heating chamber of the electric heater under pressure, the enormous heat generated by the heating element is uniformly carried away using the principles of fluid thermodynamics, ensuring that the temperature of the heated medium meets the user's process requirements.

[0003] The existing patent with publication number CN213657138U discloses a wall-mounted electric water heater for a heating system, relating to the field of electric heater technology. This utility model includes an electric heater body, which is fixedly connected to the wall via a mounting bracket. The mounting bracket includes a pair of mounting plates, which are fixedly connected by a connecting plate. A retainer is fixedly connected to the upper surface of each mounting plate, and a locking block that mates with the retainer is fixedly connected to the surface of the electric heater body. A support plate for supporting the electric heater body is fixedly connected to the mounting plate, and a pad connects the electric heater body and the support plate. This utility model simplifies the installation process and ensures structural stability by suspending the electric heater body on the mounting bracket and having the support plate support the bottom of the electric heater.

[0004] When using the mounting brackets described in the aforementioned documents for wall mounting, the fixing structure needs to be fixed to the mounting surface using expansion bolts. To ensure load-bearing capacity, most existing fixing mechanisms are non-adjustable steel frame types. After fixing the electric heater, the connection of water pipes is very inconvenient due to the small gap between the electric heater and the wall. Furthermore, the existing open structure on the back of the electric heater is connected by hooks or bolts and nuts of the mounting bracket, resulting in low connection strength and limited load-bearing capacity. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an easy-to-install electric heater fixing mechanism, which solves the problems of low connection structure strength, limited load-bearing capacity, and inconvenient pipe connection.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: an easy-to-install electric heater fixing mechanism, including a fixing frame, a pin shaft inserted inside the fixing frame, a connecting rod movably installed at the top of the fixing frame, a transmission rod movably installed at the bottom of the fixing frame, and an adjustment mechanism for adjusting the distance between the electric heater and the wall movably installed on the left side of the fixing frame;

[0007] The adjustment mechanism includes a mounting frame that is movably connected to a connecting rod and a transmission rod via a pin. A hook is provided on the left side of the mounting frame. An adapter block is movably mounted on the inner side of the mounting frame via a pin. A pneumatic pull rod is fixedly mounted on one end of the adapter block. A diagonal rod is fixedly mounted on one side of the mounting frame. A rubber pad is fixedly mounted on the top of the diagonal rod.

[0008] Preferably, the connecting rod is rotatably connected to the fixed frame at one end via a pin, and rotatably connected to the top of the mounting frame at the other end. The transmission rod has openings at both ends and in the middle that engage with the pin.

[0009] Preferably, the bottom end of the transmission rod is rotatably connected to the fixed frame via a pin, and the top end is rotatably connected to the mounting frame via a pin. The mounting frame is mirror-symmetrically installed on the front and rear sides of the fixed frame.

[0010] Preferably, the mounting frame is L-shaped, and the adapter block is mirror-symmetrically mounted on the upper and lower ends of the pneumatic rod. The pneumatic rod is rotatably connected to the pin at the corner of the mounting frame through the movable end of the adapter block.

[0011] Preferably, the fixed end of the pneumatic pull rod is rotatably connected to the pin at the center of the transmission rod, and the diagonal rod is mirror-symmetrically installed on the outer side of the mounting brackets on the front and rear sides of the fixed frame.

[0012] Preferably, the bottom of the rubber pad is fixedly connected to the front and rear diagonal bars, and the cross-section of the fixing frame, connecting rod, transmission rod, mounting frame, adapter block and diagonal bar is "L" shaped.

[0013] Beneficial effects

[0014] This invention provides an easy-to-install electric heater fixing mechanism. Compared with the prior art, it has the following advantages:

[0015] (1) The easy-to-install electric heater fixing mechanism, through the setting of the pneumatic tie rod, when the bottom of the mounting frame is in a horizontal state, the pneumatic tie rod is at its retraction limit, and the weight of the electric heater will be transmitted to the center of the transmission rod by the pneumatic tie rod, thereby supporting the mounting frame. When it is necessary to connect the water pipe, the mounting frame is pulled outward, and the external force will cause the pneumatic tie rod to extend, thereby changing the angle of each interior angle of the triangle formed between the pneumatic tie rod, the transmission rod, and the mounting frame, so that the mounting frame rotates with the center of the pin at the top of the transmission rod as the reference. The angle of each interior angle of the quadrilateral formed by the fixing frame, the connecting rod, the transmission rod, and the mounting frame will change synchronously, and the mounting frame will lift up. When there is no external force, the pneumatic tie rod can provide stable support force to keep the mounting frame at a fixed angle, thereby increasing the distance between the bottom of the electric heater above the mounting frame and the wall, so as to facilitate the installation of the water pipe after the electric heater is installed.

[0016] (2) The easy-to-install electric heater fixing mechanism, through the setting of the diagonal bar, the two ends of the diagonal bar are fixedly connected to the vertical part and the horizontal part of the mounting frame respectively, so that the corner of the mounting frame and the diagonal bar form a triangular structure to increase the strength of the mounting frame. At the same time, the cross section of the fixing frame, connecting rod, transmission rod, mounting frame, transition block and diagonal bar is "L" shaped. When the weight of the electric heater acts on the L-shaped structure, the stress will be distributed and transmitted along the two flanges to avoid local stress concentration. When one flange is compressed, the other flange is stretched, forming a moment to resist the bending moment, thereby increasing the upper limit of the bearing capacity and improving the overall strength.

[0022] 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.

[0023] Please see Figure 1-4 This utility model provides a technical solution: an easy-to-install electric heater fixing mechanism, including a fixing frame 1, a pin 11 inserted inside the fixing frame 1, a connecting rod 12 movably installed at the top of the fixing frame 1, and a transmission rod 13 movably installed at the bottom of the fixing frame 1. The connecting rod 12 is rotatably connected to the fixing frame 1 at one end through the pin 11, and rotatably connected to the top of the mounting frame 21 at the other end. The transmission rod 13 has openings at both ends and in the middle that fit into the pin 11. The bottom end of the transmission rod 13 is rotatably connected to the fixing frame 1 through the pin 11, and the top end is rotatably connected to the mounting frame 21 through the pin 11.

[0024] Specifically, the surface of the fixed frame 1 is provided with an opening structure for the installation of expansion bolts. After the fixed frame 1 is installed, it will restrict the position of one end of the connecting rod 12 and the transmission rod 13. The connecting rod 12 and the transmission rod 13 are connected to the fixed frame 1 at one end by the pin 11 and to the mounting frame 21 at the other end, forming a quadrilateral structure, so as to adjust the distance between the mounting frame 21 and the fixed frame 1 and the included angle between the mounting frame 21 and the mounting surface. The transmission rod 13 can restrict the position of the top of the pneumatic pull rod 24 when the mounting frame 21 is unfolded.

[0025] An adjustment mechanism 2 for adjusting the distance between the electric heater and the wall is movably mounted on the left side of the mounting frame 1. The adjustment mechanism 2 includes a mounting bracket 21 movably connected to a connecting rod 12 and a transmission rod 13 via a pin 11. A hook 22 is provided on the left side of the mounting bracket 21. An adapter block 23 is movably mounted on the inner side of the mounting bracket 21 via a pin 11. A pneumatic pull rod 24 is fixedly mounted at one end of the adapter block 23. A diagonal rod 25 is fixedly mounted on one side of the mounting bracket 21. A rubber pad 26 is fixedly mounted above the diagonal rod 25. The mounting bracket 21 is mirror-symmetrically mounted on the front and rear sides of the mounting frame 1. The frame 21 is L-shaped. The adapter block 23 is mirror-symmetrically installed at the upper and lower ends of the pneumatic pull rod 24. The pneumatic pull rod 24 is rotatably connected to the pin 11 at the corner of the mounting frame 21 through the movable end of the adapter block 23. The fixed end is rotatably connected to the pin 11 at the center of the transmission rod 13. The diagonal rod 25 is mirror-symmetrically installed on the outer side of the mounting frame 21 on the front and rear sides of the fixed frame 1. The bottom of the rubber pad 26 is fixedly connected to the diagonal rod 25 on the front and rear sides. The cross-section of the fixed frame 1, connecting rod 12, transmission rod 13, mounting frame 21, adapter block 23 and diagonal rod 25 is L-shaped.

[0026] Specifically, the mounting bracket 21 supports the electric heater and transmits its weight to the pneumatic pull rod 24 and the transmission rod 13. The hook 22 connects to the opening structure on the back of the electric heater, restricting its position and preventing it from sliding left or right. The adapter block 23 allows the pneumatic pull rod 24 to rotate around the center of the adapter blocks 23 at both ends. The pneumatic pull rod 24, the transmission rod 13, and the mounting bracket 21 form a triangular structure. When the bottom of the mounting bracket 21 is horizontal, the pneumatic pull rod 24 is at its retracted limit, and the weight of the electric heater is transmitted from the pneumatic pull rod 24 to the center of the transmission rod 13, thus supporting the mounting bracket 21. When a water pipe needs to be connected, pulling the mounting bracket 21 outward will cause the pneumatic pull rod 24 to extend, thereby changing the position of the pneumatic pull rod 24. The angles of the interior angles of the triangle formed between the 4-axis, the transmission rod 13, and the mounting bracket 21 cause the mounting bracket 21 to rotate around the center of the pin 11 at the top of the transmission rod 13. The angles of the interior angles of the quadrilateral formed by the fixed bracket 1, the connecting rod 12, the transmission rod 13, and the mounting bracket 21 will change synchronously, causing the mounting bracket 21 to rise. When there is no external force, the pneumatic pull rod 24 can provide stable support force to keep the mounting bracket 21 at a fixed angle, thereby increasing the distance between the bottom of the electric heater above the mounting bracket 21 and the wall. The diagonal rod 25 can increase the strength of the mounting bracket 21, and the rubber pad 26 can provide support and protection for the electric heater at the bottom. At the same time, all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0027] During operation, the pneumatic pull rod 24 is in its retracted limit when the bottom of the mounting frame 21 is horizontal. The weight of the electric heater is transmitted from the pneumatic pull rod 24 to the center of the transmission rod 13, thus supporting the mounting frame 21. When a water pipe needs to be connected, the mounting frame 21 is pulled outward, causing the pneumatic pull rod 24 to extend. This changes the angles of the interior angles of the triangle formed by the pneumatic pull rod 24, the transmission rod 13, and the mounting frame 21, causing the mounting frame 21 to rotate around the center of the pin 11 at the top of the transmission rod 13. The angles of the interior angles of the quadrilateral formed by the fixed frame 1, the connecting rod 12, the transmission rod 13, and the mounting frame 21 change synchronously, causing the mounting frame 21 to rise. When no external force is applied, the pneumatic pull rod 24 can... It provides stable support, keeping the mounting bracket 21 at a fixed angle, thereby increasing the distance between the bottom of the electric heater above the mounting bracket 21 and the wall, so as to facilitate the installation of water pipes after the electric heater is installed. The two ends of the diagonal rod 25 are fixedly connected to the vertical and horizontal parts of the mounting bracket 21 respectively, so that the corner of the mounting bracket 21 and the diagonal rod 25 form a triangular structure, thereby increasing the strength of the mounting bracket 21. At the same time, the cross-section of the fixing bracket 1, connecting rod 12, transmission rod 13, mounting bracket 21, adapter block 23 and diagonal rod 25 is "L" shaped. When the weight of the electric heater acts on the L-shaped structure, the stress will be distributed and transmitted along the two flanges, avoiding local stress concentration. When one flange is compressed, the other flange is tensile, forming a moment to resist bending moment, thereby increasing the upper limit of the load-bearing capacity and improving the overall strength.
