Description

Technical Field

[0001] The invention relates to the technical field of household appliances, and in particular to a rod assembly structure and an electric heater having the same. Background Art

[0002] Existing electric heaters, especially quick-heating furnace heaters, are popular among consumers because of their environmental protection, fast heating and no noise, and occupy a large share in the heater market. This quick-heating furnace is generally composed of a heat sink assembled from a quick-heating evaporator and an electronic control component installed at one end of the heat sink. In order to facilitate users to quickly dry clothes in the cold winter, a clothes drying rack is often installed on the upper part of the heat sink. The clothes drying rack is mainly composed of a clothes rod, a hanger arm, and a hanger arm cover. However, when the clothes rod and the hanger arm are assembled and connected, the clothes rod needs to pass through the mounting hole on the hanger arm for alignment. Not only is the assembly efficiency low, but it is also easy to scrape the glue due to inaccurate alignment, or the installation is not in place due to insufficient force. In addition, during use, it is easy for users to scrape the glue due to rotating the clothes rod, resulting in structural failure. Summary of the invention

[0003] Therefore, the technical problem to be solved by the present invention is to overcome the defects of the prior art that the clothes rod and the hanger arm are prone to scraping glue during assembly, the installation is inconvenient and the installation is not firm, so as to provide a rod assembly structure that is easy to install, firmly installed, and not prone to scraping glue, and an electric heater having the same.

[0004] In order to solve the above technical problems, the present invention provides a rod assembly structure, comprising:

[0005] The support arm has an assembly space for the rod member, and a second mounting portion adapted to the first mounting portion formed at the end of the rod member is formed on the inner peripheral wall of the assembly space, and the second mounting portion does not completely cover the circumference of the assembly space to form an assembly entrance for the rod member;

[0006] A cover body covers the opening of the support arm, and a limiting portion is formed at one end of the cover body close to the assembly space, which is used to contact the rod member after the rod member is installed in the assembly space and apply a pre-tightening force to the rod member toward the inner peripheral wall of the assembly space.

[0007] In the rod assembly structure, the second mounting portion is arranged opposite to the limiting portion of the cover body.

[0008] In the rod assembly structure, the second mounting portion is a groove or a protrusion formed on the inner peripheral wall of the assembly space at one end away from the cover body, and the corresponding first mounting portion is a protrusion or a groove formed at the end of the rod.

[0009] In the rod assembly structure, the second mounting portion is arc-shaped, and the first mounting portion is ring-shaped.

[0010] In the rod assembly structure, the limiting portion is an arc-shaped opening adapted to the peripheral wall of the rod.

[0011] The rod assembly structure is further formed with a plurality of spaced support blocks on the inner peripheral wall of the assembly space, and the support blocks are arranged in contact with the rod after the rod is installed in the assembly space.

[0012] In the rod assembly structure, the support block is formed on the upper part of the second mounting portion.

[0013] In the rod assembly structure, the cover body and the support arm are detachably connected.

[0014] In the rod assembly structure, the cover body is formed with a through hole allowing the fastener to pass through, and the corresponding position of the support arm is formed with a mounting seat for fixing the fastener.

[0015] An electric heater is also provided, comprising the rod assembly structure, wherein the rod assembly structure is a pair of rods arranged opposite to each other, and the rods are installed in the assembly spaces of a pair of supporting arms.

[0016] The technical solution of the present invention has the following advantages:

[0017] 1. The rod assembly structure provided by the present invention, when assembling the rod into the support arm, only needs to be installed along the assembly entrance in the assembly space where the second mounting portion is not provided, and the first mounting portion of the rod is matched with the second mounting portion of the assembly space, and then the cover body is covered on the opening of the support arm, so that the limiting portion of the cover body contacts the rod, and a pre-tightening force is applied to the rod toward the inner peripheral wall of the assembly space. In this way, since the rod only needs to enter from the opening of the assembly space, the phenomenon of scraping glue will not occur, and the assembly is convenient; at the same time, the rod is subjected to the pre-tightening force applied by the limiting portion of the cover body, so that it can be firmly installed in the assembly space without rotation, further avoiding the occurrence of scraping glue.

[0018] 2. In the rod assembly structure provided by the present invention, the second mounting portion and the limiting portion of the cover body are arranged opposite to each other, so that the force on the rod is more uniform and the assembly is more firm.

[0019] 3. In the rod assembly structure provided by the present invention, the second mounting portion is arc-shaped and the first mounting portion is annular, which reduces the difficulty of aligning the rod and the support arm and improves the assembly efficiency.

[0020] 4. The rod assembly structure provided by the present invention has a plurality of spaced support blocks disposed on the inner peripheral wall of the assembly space, which further improves the fixed support function of the rod and prevents the rod from shaking; and can also prevent the instability of support that may be caused by shrinkage and deformation.

[0021] 5. In the rod assembly structure provided by the present invention, the cover body and the support arm are detachably connected, which facilitates the replacement of the rod. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0033] like Figure 1-5 shows a specific implementation of the rod assembly structure, which is described by taking the assembly of a clothes rod as an example, and includes a support arm 1 and a cover body 2 covering the opening of the support arm 1. The support arm 1 is an L-shaped groove body, and an assembly space 4 for the rod 3 is provided at one end of the support arm 1, and the other end is a connection end with other carriers. A second mounting portion 6 adapted to the first mounting portion 5 formed at the end of the rod 3 is formed on the inner peripheral wall of the assembly space 4, and the second mounting portion 6 does not completely cover the circumference of the assembly space 4 to form an assembly entrance for the rod 3. In this embodiment, as shown in FIG. Figure 5 As shown, the second mounting portion 6 is formed on the left side of the assembly space 4, and the assembly entrance is formed on the right side of the assembly space 4. The cover body 2 is formed with an arc-shaped opening adapted to the peripheral wall of the rod 3 as a limiting portion 7 at one end close to the assembly space 4, which is used to contact the rod 3 after the rod 3 is installed in the assembly space 4 and apply a pre-tightening force to the rod 3 toward the inner peripheral wall of the assembly space 4.

[0034] Specifically, the second mounting portion 6 is arranged opposite to the limiting portion 7 of the cover body 2 , that is, symmetrically arranged on both sides of the rod 3 to simultaneously apply a pair of opposite forces, so that the rod 3 is more firmly installed in the assembly space 4 .

[0035] The second mounting portion 6 is an arc-shaped groove formed on the inner peripheral wall of the assembly space 4 at one end away from the cover body 2, and the corresponding first mounting portion 5 is an annular protrusion formed on the end of the rod 3. During assembly, part of the annular protrusion is inserted into the arc-shaped groove to form an interference fit to limit the movement of the rod 3 in the axial direction.

[0036] In order to further limit the movement and rotation of the rod 3 in the radial direction, a plurality of spaced support blocks 8 are formed on the inner peripheral wall of the assembly space 4. The support blocks 8 are formed on the upper part of the second mounting portion 6, are vertical strip-shaped, and the side facing the rod 3 is an arc surface. The support blocks 8 are arranged in contact with the rod 3 after the rod 3 is mounted in the assembly space 4. The support blocks 8 and the limiting portion 7 of the cover body 2 simultaneously apply a pair of opposing forces to the rod 3, so that the rod 3 is firmly limited in the assembly space 4.

[0037] In order to facilitate the assembly and replacement of the rod 3, the cover 2 is detachably connected to the arm 1. Specifically, a through hole 10 is formed on the end of the cover 2 close to the assembly space 4 to allow a screw as a fastener 9 to pass through, and a mounting seat 11 for fixing the fastener 9 is formed at a corresponding position of the arm 1. After the rod 3 is installed in the assembly space 4, the cover 2 is covered on the opening of the arm 1, and then the screw is inserted through the through hole 10 on the cover 2 into the mounting seat 11 and tightened to fix.

[0038] The present invention also provides an electric heater, such as Figure 6 As shown, the rod assembly structure includes a pair of rod assembly structures arranged opposite to each other, and the rod 3 is installed in the assembly space 4 of a pair of support arms 1. The other end of the support arm 1 is pivotally connected to a pair of opposite side walls of the electric heater body 12.

[0039] When the clothes rod needs to be assembled on the support arm 1, first insert the arc-shaped protrusion of the clothes rod into the arc-shaped groove of the assembly space 4 along the assembly entrance of the assembly space 4, and at the same time, the outer wall of the clothes rod is close to the support block 8 on the inner wall of the assembly space 4. Then cover the support arm 1, and the limit part 7 of the cover 2 is clamped on the outer wall of the clothes rod. Then insert the screw through the through hole 10 on the cover 2 and insert it into the mounting seat 11 of the support arm 1 to tighten and fix it. Finally, install the support arm 1 on the side wall of the electric heater body 12 to complete the assembly.

[0040] As an alternative embodiment, the second mounting portion 6 is an annular protrusion formed on the inner peripheral wall of the assembly space 4 at one end away from the cover body 2 , and the corresponding first mounting portion 5 is an arc-shaped groove formed at the end of the rod 3 .

[0041] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
