[0032] The utility model is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the utility model, but do not limit the utility model in any form. It should be pointed out that for those of ordinary skill in the art, several changes and improvements can be made without departing from the concept of the utility model. These all belong to the protection scope of the utility model.

[0033] like Figure 1 , Figure 2 as well as Figure 3As shown, a rotatable flip cover structure and glue gun provided by the utility model include a frame, on which at least two mounting rods 2 and a rotatable replacement bin 3 are provided, the rotatable replacement bin 3 includes at least one workpiece accommodating cavity, and one end of the rotatable replacement bin 3 is provided with an opening for allowing the workpiece to pass through. A connecting sleeve 4 rotatably connected to one mounting rod 2 is provided on one side of the rotatable replacement bin 3, the connecting sleeve 4 includes an arc-shaped limiting portion 5, and a limiting block 6 is provided on the mounting rod 2 rotatably connected to the connecting sleeve 4, the limiting block 6 is located in the arc-shaped limiting portion 5, and the limiting block 6 contacts and limits the two ends of the arc-shaped limiting portion 5. A clamping portion 7 is provided on the other side of the rotatable replacement bin 3, and the clamping portion 7 is clamped and connected to the other mounting rod 2.

[0034] By rotatably connecting one side of the rotatable replacement bin 3 to the mounting rod 2, the other side of the rotatable replacement bin 3 is clamped with the mounting rod 2. When the workpiece in the rotatable replacement bin 3 needs to be replaced, the clamping connection between the rotatable replacement bin 3 and the mounting rod 2 is released, and the rotatable replacement bin 3 is rotated to flip the rotatable replacement bin 3 from the working position. At this time, the opening of the rotatable replacement bin 3 that allows the workpiece to pass through is exposed, so that it is convenient for the staff to replace the workpiece in the accommodating cavity of the rotatable replacement bin 3. After the replacement is completed, the rotatable replacement bin 3 is rotated to the working position and the clamping portion 7 is clamped with the mounting rod 2.

[0035] With the help of the cooperation of the arc-shaped limit portion 5 and the limit block 6, the rotation range of the rotatable replacement bin 3 can be limited, and the arc angle of the arc-shaped limit portion 5 can be set according to actual needs. For example, by setting the arc angle of the arc-shaped limit portion 5, the rotatable replacement bin 3 can be rotated 120 degrees. When the rotatable replacement bin 3 is rotated to the extreme position, the rotatable replacement bin 3 can be stably maintained in this position with the help of its own gravity, which is convenient for the staff to replace the workpiece.

[0036] Furthermore, a retaining ring 8 is provided on the mounting rod 2 rotatably connected to the connecting sleeve 4, and the retaining ring 8 limits the axial displacement of the connecting sleeve 4 on the mounting rod 2. By limiting the axial displacement of the connecting sleeve 4 by the retaining ring 8, the axial displacement of the rotatable replacement bin 3 is avoided, and the rotation stability of the rotatable replacement bin 3 is improved.

[0037] Furthermore, the clamping part 7 includes an arc-shaped connecting part, and the clamping part 7 is elastic. The clamping part 7 can be made of plastic material, and the arc-shaped connecting part is easy to fit with the mounting rod 2. With the elasticity of the material of the clamping part 7 itself, the clamping connection between the clamping part 7 and the mounting rod 2 can be achieved, and the clamping state can be easily released, which is convenient to operate.

[0038] Furthermore, a raised manual flap 9 is also provided on one side of the rotatable replacement bin 3 provided with the clamping portion 7. When the workpiece needs to be replaced, the raised manual flap 9 makes it easier for the staff to rotate the rotatable replacement bin 3. The number of the connecting sleeve and the clamping portion of the present application is at least one, and multiple may also be provided.

[0039] It should be noted that the present application is particularly applicable to glue guns, and the frame is the glue gun body 1. The glue gun structure provided by the utility model also includes the glue gun body 1, and any mounting rod 2 is fixed to one end of the connecting rod glue gun body 1, and a detachable baffle 10 is provided on the side of the mounting rod 2 away from the glue gun body 1 to limit the axial movement of the rotatable replacement bin 3 along the mounting rod 2. The rotatable replacement bin 3 has an opening for allowing the workpiece to pass through, which is located on the side close to the glue gun body 1, and a glue outlet 11 is provided on the end of the rotatable replacement bin 3 away from the glue gun body 1, and the detachable baffle 10 allows the glue outlet 11 of the rotatable replacement bin 3 to pass through.

[0040] By limiting the axial displacement of the rotatable replacement bin 3 along the mounting rod 2 by means of the cooperation between the glue gun body 1 and the removable baffle 10, it is helpful to improve the stability of the installation and rotation stability of the rotatable replacement bin 3 on the glue gun body 1. The connection between the removable baffle 10 and the mounting rod 2 can be plug-in, and in order to further improve the stability of the installation of the removable baffle 10, the present application provides a feasible factual method: four mounting rods 2 can be provided, and any mounting rod 2 can be plug-in and cooperate with the removable baffle 10. The glue gun includes a manual glue gun or an electric glue gun, and the present application does not specifically limit the type of the glue gun.

[0041] The removable baffle 10 is provided with an opening 12 for allowing the glue outlet 11 to enter or escape, and the outer contour of the opening 12 is a smooth arc surface. The glue outlet 11 extends from the removable baffle 10 from the opening 12, which is convenient for glue application. The setting of the outer contour of the opening 12 as a smooth arc surface facilitates the glue outlet 11 to enter or escape from the opening 12 when the rotatable replacement chamber 3 rotates.

[0042] The present application provides a feasible practical method: the rotatable replacement chamber 3 includes two accommodating chambers for accommodating glue cartridges, thereby realizing the replacement of any glue cartridge of the multi-component glue gun, and the operation is convenient.

[0043] Preferably, a sealing plate 13 is provided at one end of the glue gun body 1 close to the rotatable replacement chamber 3, and the sealing plate 13 allows the driving part of the glue gun body 1 to pass through; a flange 14 is provided on the connecting sleeve 4, and the flange 14 is in contact with and slidably matched with the sealing plate 13. The edge profile of the position where the sealing plate 13 and the flange 14 are matched is set to an arc surface. Thereby, the stability of the rotatable replacement chamber 3 rotating on the glue gun body 1 is further improved.
