Description

Technical Field

[0001] The utility model relates to the technical field of heating devices, and particularly relates to a portable heater. Background Art

[0002] A common structure of a portable heater is a configuration in which a handle is installed on a housing. The handle is U-shaped, and both ends of the handle are hinged to the corresponding side surfaces of the housing. The housing can be lifted by holding the handle, but the hinged structure makes it impossible for the handle to stay at a desired angle when it cannot rotate relative to the housing. For example, in some application environments, the heater needs to be installed in a hanging manner. The hinged structure causes the housing and the handle not to be locked at a certain angle, and it is rather troublesome to adjust the air outlet of the housing, which needs to be improved. Content of the Utility Model

[0003] To solve the above at least one technical defect, the utility model provides the following technical solutions:

[0004] This application document discloses a portable heater, which includes a housing and a handle. The handle is U-shaped and its two ends are respectively pivotally connected to the opposite side surfaces of the housing. A locking mechanism is further included. The locking mechanism includes a first sleeve, a second sleeve, and an arc-shaped pressing block. The first sleeve and the second sleeve are sleeved together, and the second sleeve is fixed to the side surface of the housing. The second sleeve is sleeved on the end of the handle. A pressing block is arranged on the inner wall of the second sleeve, and a part of the pressing block extends out from the peripheral wall of the second sleeve. The first sleeve is threadedly connected to the second sleeve, and the first sleeve is in inclined surface contact with the part of the pressing block extending out from the peripheral wall of the second sleeve. Moving down the first sleeve synchronously causes it to squeeze the pressing block to fix the end of the handle.

[0005] In this solution, a locking mechanism is installed between the end of the handle and the housing. The first sleeve can be rotated to move down relative to the second sleeve. The first sleeve squeezes the pressing block to move it inward, and the pressing block presses and fixes the end of the handle, so that the housing and the handle are maintained at a suitable angle, which is convenient for use and adjusting the air outlet direction.

[0006] Further, there are multiple pressing blocks distributed around the end of the handle. The extrusion and fixation by multiple pressing blocks help improve stability.

[0007] Further, the part of the pressing block exposed on the peripheral wall of the second sleeve is formed with an inclined surface, and a corresponding inclined surface is formed on the inner wall of the bottom of the first sleeve. The abutment of the double inclined surfaces helps improve the stability of movement.

[0008] Further, an elastic member is arranged between the pressing block and the inner wall of the second sleeve. The elastic member is used to reset the pressing block. After the first sleeve is lifted and reset, the elastic member quickly resets the pressing block to release the locking of the handle.

[0009] Further, through holes are formed at intervals in the circumferential direction on the circumferential surface of the second sleeve. The pressing block is L-shaped, the horizontal end of the pressing block extends out from the through hole, and an elastic member is arranged between the vertical end of the pressing block and the cavity wall inside the second sleeve. The through holes and the specific configuration of the pressing block facilitate assembly and molding, as well as the placement of the elastic member.

[0010] Further, ribs are formed at intervals in the circumferential direction on the circumferential surface of the first sleeve, which facilitates applying force to twist the first sleeve to rotate.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. The present utility model adds a locking mechanism, which can lock the handle relative to the housing at a required angle, facilitating operation and use. When the handle is suspended, it is convenient to adjust the air outlet direction. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following will further illustrate the present utility model in conjunction with the drawings and specific embodiments.

[0019] Embodiment 1

[0020] In this example, a portable heater includes a housing and a handle. As Figure 1 shown, the housing 1 adopts a common box shape. An air outlet is formed on the left side surface of the housing 1. The handle 2 is U-shaped and its two ends are respectively pivotally connected to the front and rear side surfaces of the housing 1. This is a conventional configuration.

[0021] In this example, a locking mechanism is added. The locking mechanism includes a first sleeve 3, a second sleeve 4, and an arc-shaped pressing block 6. The first sleeve 3 and the second sleeve 4 are sleeved together. A threaded surface is formed in the cavity of the outer first sleeve 3, and a corresponding meshing threaded surface is formed on the circumferential surface of the second sleeve 4. The first sleeve 3 and the second sleeve 4 are concentrically arranged, and the second sleeve 4 is fixed to the side surface of the housing 1, such as by bolts.

[0022] As Figure 1 , Figure 2 shown, the second sleeve 4 is sleeved at the end of the handle 2. An installation space is pre-formed on the cavity wall of the second sleeve 4 around the end of the handle 2. A plurality of arc-shaped pressing blocks 6 are circumferentially and spacedly arranged in the installation space, so that the pressing blocks 6 surround the end 21 of the handle. A plurality of through holes are circumferentially and spacedly formed on the circumferential surface of the second sleeve 4, and a part of the pressing block 6 extends out of the through holes.

[0023] For the configuration of the pressing block, for example, the cross-section of the pressing block 6 is L-shaped. The longitudinal end of the pressing block 6 is in the installation space of the second sleeve 4, and the transverse end of the pressing block 6 extends out of the through hole radially formed on the cavity wall of the second sleeve 4 to be in an exposed state. For convenient assembly, the longitudinal end and the transverse end of the pressing block 6 are in a split form, and the longitudinal end and the transverse end are fitted and fixed to form the pressing block. A slope 61 is formed on the end face of the transverse end of the pressing block, and a slope is also formed on the bottom cavity wall of the first sleeve 3. The two slopes are fitted together.

[0024] Under this structure, when the first sleeve 3 is rotated to move downward relative to the second sleeve 4, the first sleeve 3 presses the pressing block, and then the pressing block moves radially so that its longitudinal end abuts against and presses the end of the handle, thereby restricting its rotation, keeping the housing and the handle at a proper angle. After that, operations such as hanging can be performed through the handle, which is convenient for adjusting the air outlet direction.

[0025] To facilitate the rotation of the first sleeve, convex ribs 5 can also be circumferentially and spacedly formed on the circumferential surface of the first sleeve 3. The concave-convex configuration formed by the spaced convex ribs is convenient for exerting force.

[0026] In addition, an elastic layer can be coated on the longitudinal end of the pressing block 6 or a frosted surface can be formed, etc., to better limit the end of the handle.

[0027] An elastic member can also be added. For example, an elastic member 7, such as a spring, is arranged between the longitudinal end of the pressing block 6 and the cavity wall of the second sleeve 4. The elastic member is used to reset the pressing block. After the first sleeve moves up and resets, the elastic member quickly resets the pressing block to release the lock on the handle.

[0028] The above is only the preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions within the idea of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present invention should also be regarded as within the protection scope of the present invention.
