Description

Technical Field

[0001] This utility model relates to the field of printed heat dissipation components, and in particular to a double-layer shock-absorbing fan fixing structure. Background Technology

[0002] When printing paper products, it is usually necessary to use a drying and heat dissipation assembly. Existing cooling fans are directly fixed to the mounting plate during use, which can accommodate multiple fans at the same time. In order to improve the efficiency of drying and heat dissipation, in some application environments, the fans need to be set to be movable. During the movement or in some vibrating environments, the fixed position of the fan is easily affected by vibration, which not only affects the service life of the fan, but may also damage the fan in severe cases. Utility Model Content

[0003] The purpose of this invention is to provide a double-layer shock-absorbing fan fixing structure. In use, it can simultaneously stack and fix two fans together. During installation, the convenient mounting slot on the right side allows for staggered insertion with the structure at the installation location, resulting in stronger load-bearing capacity during tightening. After installation, the front and rear fans, through the shock-absorbing deformation safety slots between them, ensure that they do not affect each other during use. Furthermore, it can absorb vibrations during use, thus improving the overall shock resistance, extending the fan's lifespan, and enhancing safety during operation.

[0004] The technical solution of this utility model is as follows: A double-layer shock-absorbing fan fixing structure is characterized by: a cylindrical main body with a central axis pointing forward and backward; a cylindrical central clearance hole penetrating the entire structure in the forward and backward direction at the central axis position of the main body with a central axis; an integrally formed mounting plate on the right side of the main body with a central clearance hole; a convenient mounting groove penetrating the entire structure in the forward and backward direction and on the right side; an integral mounting hole at the upper end of the integral mounting plate; circumferentially distributed fan mounting brackets on the outer cylindrical surface of the main body with a fan fastening hole on the front side of each fan mounting bracket; and a shock-absorbing deformation safety groove opening to the left and penetrating the lower end of the entire structure at the upper end of the main body with a left-right direction, the depth of the shock-absorbing deformation safety groove being greater than two-thirds of the diameter of the main body with a central axis.

[0005] Furthermore, the shock-absorbing deformation safety groove is located at the center position of the main body mating connecting seat in the front-rear direction.

[0006] Furthermore, the width of the overall mounting plate in the front-to-back direction is the same as the thickness of the main body connecting seat in the front-to-back direction.

[0007] Furthermore, the right side of the overall mounting plate is provided with a recessed mounting arc surface.

[0008] Furthermore, the thickness of the fan mounting bracket in the front-to-back direction is the same as the thickness of the main body connecting seat in the front-to-back direction.

[0009] The beneficial effects of this utility model are: This invention allows two fans to be stacked and fixed together simultaneously. During installation, the convenient mounting slot on the right side allows for staggered insertion into the structure of the installation location, resulting in stronger load-bearing capacity during fastening. After installation, the front and rear fans are protected by shock-absorbing deformation safety slots between them, ensuring that they do not interfere with each other during use. Furthermore, the slots can absorb vibrations during use, thus improving the overall shock resistance, extending the lifespan of the fans, and enhancing safety during operation.

[0011] like Figures 1 to 7As shown, a double-layer shock-absorbing fan fixing structure includes a cylindrical main body connecting seat 1 with its central axis pointing forward and backward. The main body connecting seat 1 has a cylindrical central clearance hole 2 that extends forward and backward, accommodating the fan's ventilation space. An integrally formed mounting plate 3 is located on the right side of the main body connecting seat 1, allowing for overall installation and fixing, combining two fans as a module for easier installation. To the right of the central clearance hole 2 is a convenient installation groove 4 that extends forward and backward and to the right side, allowing for interlocking insertion with the installation structure for better stability. The upper end of the integral mounting plate 3 has an integral mounting hole 5 for screw installation and fixing. The outer cylindrical surface of the main body connecting seat 1 has circumferentially distributed fan mounting brackets 6, with fan fastening holes 7 on their front sides for securing the fan. The upper end of the main body connecting seat 1 is provided with a shock-absorbing deformation safety groove 8 that opens to the left and completely penetrates the lower end of the entire structure. This ensures that there is a certain deformation space between the front and rear structures during use, which can play a role in deformation buffering in a vibration environment, ensuring better shock absorption for the fans fixed in the front and rear positions during use. The depth of the shock-absorbing deformation safety groove 8 in the left and right directions is greater than two-thirds of the diameter of the main body connecting seat 1, ensuring the deformation effect during shock absorption. If this length is too small, the shock absorption effect cannot be achieved. During use, it can simultaneously fix two fans together in a stacked manner. During installation, the convenient installation groove on the right side allows for staggered insertion with the structure at the installation position, resulting in stronger load-bearing capacity during fastening. After the front and rear fans are installed, the shock-absorbing deformation safety groove between them ensures that they do not affect each other during use and can absorb vibrations during use, thus improving the overall shock resistance, ensuring a longer service life, and enhancing safety during use.

[0012] Preferably, the shock-absorbing deformation safety groove 8 is located at the center of the main body and the connecting seat 1 in the front-rear direction, which makes the overall structural support strength better and the service life longer during use.

[0013] Preferably, the width of the overall mounting plate 3 in the front-to-back direction is the same as the thickness of the main body connecting seat 1 in the front-to-back direction, so that the flatness of the installation and fastening position is better and the bearing capacity of the fastening is higher.

[0014] Preferably, the right side of the overall mounting plate 3 is provided with a recessed arc surface, which occupies less space during installation and provides better safety during installation, and will not affect other structures during installation.

[0015] Preferably, the thickness of the fan mounting bracket 6 in the front-to-back direction is the same as the thickness of the main body connecting seat 1 in the front-to-back direction, which makes the structural strength at this position higher and the fit strength when fastening with the fan more reliable.

[0016] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements or substitutions can be made without departing from the principle of this utility model, and these improvements or substitutions should also be considered within the protection scope of this utility model.
