Description

Technical Field

[0001] This utility model relates to the field of heater technology, and in particular to a heater with an adjustable pitch angle. Background Technology

[0002] Heaters use electricity as their primary energy source and provide warmth to the human body through direct contact, warm air convection, and far-infrared radiation. They are widely used in various civil and public buildings, including residences, offices, hotels, shopping malls, hospitals, schools, train carriages, mobile heating systems, and simple prefabricated houses.

[0003] A Chinese patent with publication number CN221923649U discloses a multi-angle adjustable electric heater, including a mounting base, a mounting unit rotatably connected to the mounting base, a heating element rotatably connected to the mounting unit, and a pin disposed between the heating element and the mounting unit. The central axis of the pin is perpendicular to the rotation axis of the rotating platform.

[0004] However, the above-mentioned multi-angle adjustable electric heater has the following disadvantages: it is difficult to keep the angle of the heating element fixed when rotating to adjust the pitch angle. Utility Model Content

[0005] The purpose of this invention is to provide a heater with an adjustable pitch angle, which has the effect of adjustable pitch angle and the heating element assembly can be fixed at different angles.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an adjustable pitch angle heater, including a base body and a heating element assembly, the base body including a hinge portion, the heating element assembly including a rotating connection portion, the rotating connection portion rotatably engaging with the hinge portion, and a locking positioning structure provided between the rotating connection portion and the hinge portion, the locking positioning structure including a plug post, a spring and a plurality of plug holes, the plurality of plug holes being spaced apart on the hinge portion along the rotation direction of the rotating connection portion, and the spring having a tendency to push the end of the plug post to lock into the plug hole.

[0007] By adopting the above technical solution, when the heating element assembly rotates, it drives the rotating connection part to rotate to adjust the pitch angle. During the rotation, the plug on the rotating connection part tends to move towards the hinge part. When the plug rotates to the plug hole along the rotation direction, under the action of the spring force, the plug springs into the plug hole, thereby locking the plug and fixing the heating element assembly at the current pitch angle.

[0008] A further feature of this invention is that the end of the plug near the hinge portion is provided with a guide surface, and the end of the plug is guided and engaged with the plug hole through the guide surface.

[0009] By adopting the above technical solution, the plug is guided into the plug hole along the guide surface when it is inserted. When the user continues to adjust the pitch angle of the heating element assembly, the plug is guided out of the plug hole along the guide surface by rotating the heating element assembly. This makes it easier for the plug to slide along the rotation direction to adjust the pitch angle of the heating element assembly, thus improving the user's ease of operation.

[0010] A further feature of this invention is that the rotating connection portion has an installation groove for mounting the insertion post, and the spring is disposed within the installation groove.

[0011] By adopting the above technical solution, the plug and spring are positioned in the mounting groove, which improves the ease of installation of the plug and spring.

[0012] A further feature of this invention is that the hinge portion includes a positioning disk located on the side of the rotating connection portion, and a plurality of insertion holes are spaced apart circumferentially on the positioning disk.

[0013] By adopting the above technical solution, the rotating connection part is positioned and installed by the positioning plate, which improves the ease of installation of the heater.

[0014] A further feature of this invention is that the positioning disk is provided with a positioning post, the positioning post is located on the side of the positioning disk near the base body, the hinge part is provided with a corresponding positioning hole, and the positioning disk is positioned and engaged with the hinge part through the positioning post.

[0015] By adopting the above technical solution, the positioning pin is inserted into the positioning hole during installation, which improves the accuracy of positioning plate installation and facilitates the installation of positioning plate.

[0016] A further feature of this invention is that: a first through hole is provided on the positioning disk, a second through hole is provided on the hinge part, and end caps are provided on both sides of the base body. The end caps are fixedly connected to the hinge part, and the end caps include a positioning part. The positioning part passes through the first through hole and the second through hole and is positioned and engaged with the rotating connection part.

[0017] By adopting the above technical solution, end caps are set on both sides of the base body to facilitate the protection of the internal structure. When installing the end caps, the user can position them through the positioning part, which improves the installation accuracy and convenience of the end caps.

[0018] A further feature of this invention is that the positioning part is provided with a plurality of positioning ribs on the side near the rotating connection part, and the rotating connection part is provided with a corresponding positioning groove. The positioning ribs pass through the second through hole and the first through hole and are engaged with the positioning groove to prevent rotation.

[0019] By adopting the above technical solution, when the end cover is installed, the positioning protrusion on the positioning part is inserted into the positioning groove to realize the insertion and positioning of the end cover. At the same time, when the positioning protrusion is inserted into the positioning groove, the end cover and the rotating connection part are anti-rotationally engaged. The stability of the positioning part and the rotating connection part during positioning and installation is improved by a number of positioning protrusions, thereby improving the installation stability of the end cover and the rotating connection part.

[0020] A further feature of this invention is that an angle limiting structure is provided between the end cap and the hinge portion, and the rotating connection portion is limited and engaged with the base body through the end cap.

[0021] By adopting the above technical solution, when the heating element assembly rotates, the rotating connection part drives the end cover to rotate. The end cover and the hinge part are limited by the angle limiting structure, so that the rotation of the end cover is restricted when the heating element assembly rotates to the maximum angle, thereby limiting the rotation of the rotating connection part, preventing the heating element assembly from being damaged by excessive rotation, and improving the durability of the equipment.

[0022] A further feature of this invention is that the angle limiting structure includes a limiting protrusion and a limiting groove. The limiting protrusion is located inside the end cap, and the limiting groove is formed on the hinge portion. The limiting protrusion is constrained within the limiting groove and slides in cooperation with it.

[0023] By adopting the above technical solution, when the end cover rotates, it drives the limiting protrusion to rotate in the direction of rotation. The limiting protrusion is inserted into the annular limiting groove and slides along the limiting groove. When the heating body assembly rotates to the maximum rotation angle, the limiting protrusion abuts against the side wall of the limiting groove, thereby realizing the limiting cooperation between the end cover and the hinge.

[0024] A further feature of this invention is that the rotating connection part is fixedly connected to the middle part of the heating element assembly, and the rotating connection part is located on the side of the heating element assembly close to the base body.

[0025] By adopting the above technical solution, the rotating connection is fixedly connected to the middle of the heating element assembly, so that the center of gravity of the heating element assembly is not easily deviated during the rotation of the heating element assembly, thereby improving the stability of the heating element assembly.

[0026] In summary, this utility model has the following beneficial effects:

[0027] 1. A locking and positioning structure is adopted between the rotating connection part and the hinge part, and the rotating connection part and the hinge part are rotated together, which has the effect of adjustable pitch angle of heating element assembly.

[0028] 2. A rotating connection part with a spring and a plug-in post and a positioning plate with a plug-in hole are adopted. The plug-in post is springed into the plug-in hole by the spring, which has the effect of fixing the pitch angle of the heating element assembly.

[0029] 3. An angle limiting structure is adopted on the end cap and the base body, which has the effect of limiting the rotation angle of the heating element assembly, thereby improving the durability of the equipment. Attached Figure Description

[0037] The present invention will be further described below with reference to the accompanying drawings.

[0038] A heater with an adjustable tilt angle, such as Figure 1-3 As shown, the device includes a base body 1 and a heating element assembly 2. The base body 1 includes a hinge portion 10, and the heating element assembly 2 includes a rotating connection portion 3. The rotating connection portion 3 is rotatably engaged with the hinge portion 10. A locking and positioning structure 4 is provided between the rotating connection portion 3 and the base body 1. The locking and positioning structure 4 includes a plug post 42, a spring 43, and several plug holes 411. The plug holes 411 are spaced apart on the hinge portion 10 along the rotation direction of the rotating connection portion 3. When the heating element assembly 2 rotates, it drives the rotating connection portion 3 to rotate to adjust the pitch angle. During the rotation, the plug post 42 on the rotating connection portion 3 tends to move towards the hinge portion 10. When the plug post 42 rotates to the plug hole 411 along the rotation direction, under the elastic force of the spring 43, the plug post 42 springs into the plug hole 411, thereby locking the plug post 42 and fixing the pitch angle of the heater.

[0039] like Figure 2 , 3 As shown, in this embodiment, the rotating connection part 3 has a mounting groove 31 for inserting the spring 43 and the plug post 42. The hinge part 10 includes a positioning plate 41. When the heating body assembly is rotated, the plug post 42 located in the mounting groove 31 tends to move towards the positioning plate 41 under the action of the spring 43. The plug post 42 is provided with a guide surface 421. When the end of the plug post 42 rotates to the plug hole 411, the plug post 42 is guided along the guide surface 421 and inserted into the plug hole 411. When the heating body assembly 2 continues to rotate, the plug post 42 slides out of the plug hole 411 along the guide surface 421 and continues to slide to the next plug hole 411. Guided by the guide surface 421, it is convenient for the user to rotate the heating body assembly 2. In addition, the positioning plate 41 is also provided with a positioning post 412. The positioning post 412 is inserted into the positioning hole 11 on the hinge part 10, which is convenient for the positioning and installation of the positioning plate 41.

[0040] like Figure 5 , 6 As shown, in this embodiment, the base body 1 has end caps 13 on both sides to protect the internal structure. Each end cap 13 includes a positioning part 131, which passes through a first through hole 413 on the positioning plate 41 and a second through hole 12 on the hinge part 10, and is positioned and engaged with the rotating connection part 3. Several positioning ribs 132 are provided at one end of the end cap 13 near the rotating connection part 3, and corresponding positioning grooves 32 are provided on the rotating connection part 3. When the end cap 13 is installed, the positioning ribs 132 are inserted into the positioning grooves 32, at which point the end cap 13 and the rotating connection part 3 are engaged to prevent rotation. Furthermore... An angle limiting structure 5 is provided between the end cap 13 and the hinge portion 10. The angle limiting structure 5 includes a limiting protrusion 51 disposed on the inner side of the end cap 13 and a limiting groove 52 opened in the hinge portion 10. The limiting groove 52 is opened in the rotation direction. The limiting protrusion 51 is constrained in the limiting groove 52 and slides with it. When the heating body assembly 2 rotates, it drives the end cap 13 to rotate, so that the limiting protrusion 51 slides in the limiting groove 52 in the rotation direction. When the heating body assembly 2 rotates to the maximum rotation angle, the limiting protrusion 51 abuts against the side wall of the limiting groove 52, thereby realizing the limiting cooperation between the end cap 13 and the hinge portion 10.

[0041] like Figure 1 As shown, in this embodiment, the rotating connection part 3 is located in the middle of the heating body assembly 2, so that the center of gravity of the heating body assembly 2 is not easily deviated during the rotation process, thereby improving the stability of the heating body assembly 2.

[0042] The basic working principle of this utility model is as follows: a locking and positioning structure 4 is provided between the hinge part 10 and the rotating connection part 3. Several insertion holes 411 are provided on the hinge part 10 along the rotation direction. When the user rotates the heating body assembly 2, the insertion post 42 slides along the rotation direction. When the insertion post 42 slides to the insertion hole 411, the spring 43 pushes the insertion post 42 to move into the insertion hole 411, so that the insertion post 42 is locked in the insertion hole 411, thereby fixing the pitch angle of the heating body assembly 2. When the heating body assembly 2 continues to rotate, the insertion post 42 is inserted into different insertion holes 411, so that the heating body assembly 2 has different pitch angles.

[0043] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
