[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0018] Embodiment

[0019] See also Figures 1 to 3 , is an embodiment of the utility model, which provides a technical solution: a spring support structure of a print head assembly, comprising

[0020] A base 1, a T-shaped slide groove 11 provided on the surface of the base 1, a rectangular base 2 provided on the front surface of the base 1, a T-shaped slide 21 welded and fixed to the rear surface of the rectangular base 2 and slidably located in the T-shaped slide groove 11, a support sleeve 3 rotatably installed on the front surface of the rectangular base 2, and the support sleeve 3 is located at the arc-shaped bending area 61 at the center of the print head spring piece 6, which can support the print head spring piece 6, and the rotation design of the support sleeve 3 can reduce the friction between the print head spring piece 6 and the arc-shaped bending area 61, so that when the print head spring piece 6 rotates under the support of the support sleeve 3, the support sleeve 3 can also rotate, which can reduce the friction resistance compared with the traditional fixed round shaft;

[0021] The adjustment mechanism 5 arranged between the rectangular seat 2 and the base 1 includes an inner slide groove 53 provided inside the rectangular seat 2, a spring 54 and an inner slide block 55 installed in the inner slide groove 53, a side clamp rod 58 welded and fixed to the rear surface of the inner slide block 55, and a plurality of limit clamp holes 52 provided on the inner wall of the T-shaped slide groove 11. The end of the side clamp rod 58 passes through the shift block 51 and penetrates into one of the limit clamp holes 52, which can stably limit the T-shaped slide seat 21 and the rectangular seat 2 to ensure the stability of the support sleeve 3 during daily use. The upper and lower surfaces of the inner slide block 55 are fixed with side connecting blocks 56, and the upper and lower surfaces of the rectangular seat 2 are provided with side slideways 57 corresponding to the side connecting blocks 56. The end of the side connecting block 56 penetrates to the side slideway 57 through the side slideway 57. The surface of the rectangular seat 2 is fixed with a shift block 51, so that the subsequent operator can shift the side connecting block 56 and the inner sliding block 55 sideways by shifting the shift block 51, and compress the spring 54 until the end of the side clamping rod 58 moves out of the limit clamping hole 52, so that the limit on the T-shaped slide 21 can be released. At this time, the rectangular seat 2 can be slid up and down on the front surface of the base 1 to adjust the height of the support sleeve 3. When it is adjusted to a suitable height, the shift block 51 is released, the spring 54 will push the inner sliding block 55 back to reset, and the end of the side clamping rod 58 is inserted into the limit clamping hole 52 at other positions, so that the T-shaped slide 21 can be limited again, so as to realize the rapid adaptive adjustment of the height of the support sleeve 3 and meet the support of the print head spring 6 under different conditions.

[0022] Among them, a circular groove A is opened on the front surface of the inner sliding block 55, and the rear end of the spring 54 is inserted into the circular groove A. A circular groove B is opened on the inner wall of one end of the inner sliding groove 53, and the front end of the spring 54 is inserted into the circular groove B. The design of the two circular grooves can limit the spring 54 to prevent the spring 54 from running off.

[0023] A through hole is formed on the surface of the T-shaped slide seat 21 for the side clamping rod 58 to pass through.

[0024] Among them, the top end of the T-shaped sliding groove 11 communicates with the top surface of the base 1, and the bottom end of the T-shaped sliding groove 11 communicates with the bottom surface of the base 1, so that the T-shaped sliding seat 21 can slide out from the top end or the bottom end of the T-shaped sliding groove 11, facilitating the disassembly and assembly between the rectangular seat 2 and the base 1.

[0025] Among them, a base rod 7 is fixed on the front surface of the rectangular seat 2, and the support sleeve 3 is rotatably sleeved on the base rod 7 to realize the smooth rotational installation of the support sleeve 3. The front end of the base rod 7 is welded and fixed with an anti-slip-off block 4, and the anti-slip-off block 4 is directly in front of the support sleeve 3, which can prevent the support sleeve 3 from slipping off the front end of the base rod 7.

[0026] Although the embodiments of the present invention have been shown and described (see the above detailed description), for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
