Description

Technical Field

[0001] This utility model relates to the field of hot air gun technology, and in particular to a clamping mechanism and a hot air gun. Background Technology

[0002] Currently, most hot air gun nozzle assemblies use standard round nozzles, flat nozzles, concentrating nozzles, adjustable nozzles, and insulated nozzles. While there are various nozzle shapes, existing nozzles may not be suitable for certain special shapes or irregular objects. This leads to operators holding the hot air gun for extended periods, resulting in uneven hot air distribution to the target equipment. For example, when heating temperature sensors in confined spaces for 3-5 minutes, inconsistent heating positions make it difficult to ensure even hot air coverage. Holding a heavy hot air gun for extended periods not only causes operator fatigue but also can lead to instability due to hand tremors, potentially affecting heating accuracy and even causing safety accidents. Utility Model Content

[0003] In view of the problems of inconvenient operation and lack of safety in the use of hot air guns mentioned above or in the prior art, this utility model is proposed.

[0004] Therefore, the purpose of this utility model is to provide a clamping mechanism and a hot air gun, which can quickly fix the hot air gun to the component to be heated, providing stable support for operation and maintenance personnel, so that they do not need to hold it for a long time, reducing the burden and improving convenience.

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0025] Example 1

[0026] Reference Figures 1-4 This is the first embodiment of the present invention. This embodiment provides a clamping mechanism that can quickly fix the hot air gun to the component to be heated, providing stable support for operation and maintenance personnel, so that they do not need to hold it for a long time, reducing the burden and improving convenience.

[0027] Specifically, it includes a clamping unit 1, a fixing component 11, and a nozzle body 12 fixedly connected to the bottom of the fixing component 11;

[0028] The fixing component 11 is used to quickly fix the air outlet of the hot air gun to the item to be heated.

[0029] The nozzle body 12 is used to evenly disperse the hot air blown out by the hot air gun.

[0030] In use, first align the nozzle body 12 with the heating position of the item to be heated. Second, move the fixing component 11 to open it to a certain angle. Finally, release the fixing component 11, which, under the action of elastic force, tightly clamps the item to be heated, completing the clamping and fixing work.

[0031] Example 2

[0032] Reference Figures 1-4 This is the second embodiment of the present invention, which differs from the first embodiment in that it further includes a fixing component 11, including a fixing clamp 111, connecting rods 112 that are telescopically connected to both ends of the fixing clamp 111, and a connecting shaft 113 that is rotatably connected to the connecting rods 112.

[0033] Furthermore, two sets of fixing clamps 111 are provided, symmetrically arranged on both sides of the connecting shaft 113; four sets of connecting rods 112 are provided, with two sets of connecting rods 112 on each set of fixing clamps 111; each pair of connecting rods 112 is rotatably connected to both sides of the connecting shaft 113. This symmetrical structure ensures the balance of clamping and prevents the hot air gun from shaking during operation.

[0034] Preferably, by setting two sets of fixing clips 111, the mechanism is firmly fixed to both ends of the item to be heated, preventing it from falling off during actual operation. The fixing clips 111 and the connecting rod 112 are designed to be telescopic, which facilitates storage and length adjustment during use.

[0035] Furthermore, the connecting rod 112 includes a U-shaped block 1121 fixedly connected to the outer wall of the connecting rod 112, and a round hole 1122 opened on the connecting rod 112 near one end of the connecting shaft 113; the connecting shaft 113 is inserted into the round hole 1122.

[0036] Furthermore, the fixing component 11 also includes springs 114; two sets of springs 114 are provided, and each set of springs 114 is fixedly connected to a U-shaped block 1121 at both ends.

[0037] Furthermore, a rubber circular sleeve 1111 is fixedly installed on the fixing clamp 111. The advantage of this design is that it can both enhance the friction between the clamp and the workpiece and provide protection.

[0038] When using, first open the retaining clip 111, accurately place it in the appropriate position on the item to be heated, and then release your hand. The spring 114 returns to its original deformation, and the resulting elastic force causes the retaining clip 111 to firmly clamp the item to be heated.

[0039] Furthermore, the nozzle body 12 includes an air inlet duct 121 fixedly connected to the connecting shaft 113, a connecting tube 122 sleeved on the upper end of the air inlet duct 121, and an air outlet duct 123 sleeved on the upper end of the connecting tube 122.

[0040] Furthermore, the interiors of the air inlet duct 121, the connecting duct 122, and the air outlet duct 123 are all designed as hollow structures.

[0041] Furthermore, the shape of the fixing clip 111 is L-shaped.

[0042] Preferably, the nozzle body 12, the fixing clamp 111, the connecting shaft 113 and the spring 114 are all made of high-strength alloy steel and have undergone heat treatment, possessing both good strength and toughness.

[0043] It should be noted that during the heating process, the air inlet 121 is tightly connected to the hot air gun outlet, ensuring that hot air can smoothly enter the nozzle body 12. Since the fixing component 11 stably fixes the hot air gun, the operator does not need to hold it, avoiding the impact of hand fatigue and shaking on the heating effect, and ensuring the accuracy and stability of heating. The nozzle body 12 consists of an air inlet 121, a connecting cylinder 122, and an air outlet 123, each with a hollow internal structure. Hot air enters the air inlet 121 from the hot air gun outlet. The nested design between the air inlet 121, the connecting cylinder 122, and the air outlet 123 allows the hot air to gradually and evenly disperse during transmission, finally being blown out from the air outlet 123, evenly acting on the item to be heated.

[0044] Working Principle: When the operator opens the fixing clamp 111, the telescopic spring 114 is stretched, storing elastic potential energy. When the fixing clamp 111 is placed in a fixed position such as a junction box and the operator releases their hand, the telescopic spring 114 returns to its original deformation, releasing the elastic potential energy. The resulting elastic force causes the fixing clamp 111 to tightly clamp the junction box, achieving stable fixation of the hot air gun. The rubber circular sleeve 1111 at the front end of the fixing clamp 111 is made of soft and high-friction rubber. During the fixing process, on the one hand, it increases the friction between the fixing clamp and the object to be heated, ensuring that the fixing clamp 111 is not easy to slip; on the other hand, the soft texture of the rubber circular sleeve 1111 can effectively prevent scratches on the surface of the work object during the fixing process. The air inlet 121 is fixedly connected to the connecting shaft 113, and one end of it is connected to the air outlet of the hot air gun. Hot air enters the air inlet 121 from the air outlet of the hot air gun. The inner diameter and length of the air inlet 121 are optimized to maintain a good flow rate and pressure when the hot air enters. The connecting cylinder 122 is fitted onto the upper end of the air inlet duct 121, and its inner diameter is slightly larger than that of the air inlet duct 121. This design slows down the flow rate of hot air when it enters the connecting cylinder 122, resulting in a more uniform pressure distribution. The air outlet duct 123 is fitted onto the upper end of the connecting cylinder 122, and its internal structure further rectifies and disperses the hot air.

[0045] Reference Figures 1-3 This is the third embodiment of the present invention, which provides a hot air gun.

[0046] Specifically, it includes a gun body 2 mounted on the air inlet duct 121, and a handle 3 fixedly connected to the gun body 2.

[0047] Preferably, handle 3 is easy for the operator to hold during the operation of the hot air gun.

[0048] It should be noted that the main function of the gun body 2 is to generate hot air, providing the necessary heat source for the heating operation. When the hot air gun is working, the heating element inside the gun body 2 converts electrical energy into heat energy, causing the passing air to heat up rapidly, forming high-temperature hot air. This hot air is discharged through the air outlet and enters the nozzle body 12.
