A floor scrubber tail assembly assembly equipment

Abstract

This utility model discloses an assembly device for a floor scrubber's swing tail assembly. Relating to the field of floor scrubber technology, the device includes a main body of the swing tail weldment, a swing tail movable plate, and two mounting seats. The main body of the swing tail weldment is equipped with a spring suspension plate and a welding fixing sleeve. Circular grooves are formed on both sides of the welding fixing sleeve. A bolt connects the swing tail movable plate to the main body of the swing tail weldment. By setting up a swing support assembly, when the main body of the swing tail weldment swings up and down on a hollow cylinder through the circular grooves, the connecting seat can slide along the direction of the arc-shaped rod, thereby driving the extension and contraction of the upper and lower arc-shaped springs. This does not affect the up-and-down swing of the main body of the swing tail weldment. Furthermore, in conjunction with the tension spring on the spring suspension plate, it can further support the swing tail assembly, improving its service life. It also occupies little space and is highly practical. Even if either the tension spring or the arc-shaped spring is damaged, the up-and-down swing of the swing tail assembly can continue.

Description

Technical Field

[0001] This utility model relates to the field of floor scrubber technology, specifically to a floor scrubber tail assembly assembly device. Background Technology

[0002] The front end of the floor scrubber's swing assembly is connected to the frame, i.e., fixed to the rear of the floor scrubber frame. The rear brush is installed at the rear. The swing amplitude is adjusted by structural components to achieve the maximum cleaning area, and it can also perform secondary cleaning. The swing assembly mainly swings up and down and left and right. For example, patent document CN119055141A, entitled "A Multifunctional Chassis Structure for a Floor Scrubber", uses a hydraulic rod to adjust the angle of the cleaning module and the dirt collection module through the swing assembly, so that the suction head can fit in close to the ground, improving the cleaning efficiency of the wastewater on the ground. The electric cleaning roller performs self-cleaning while adsorbing and cleaning the dust and impurities remaining on the ground. This technical solution also adjusts the cleaning effect through the swing assembly.

[0003] In the prior art, the tail assemblies are generally connected by a tension spring, and the tail assemblies can swing up and down through the pivot structure. However, relying solely on the tension spring for support can easily lead to overstretching of the tension spring, affecting the use of the tail assemblies. Furthermore, when installing the tail assemblies with the pivot, it is necessary to hold the tail assemblies with one hand and insert the bolts with the other, which is quite laborious. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a floor scrubber tail assembly assembly device, which solves the problems existing in the above-mentioned prior art.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a floor scrubber tail assembly assembly equipment, including a tail welding component body, a tail movable plate and two mounting seats, wherein a spring hanging plate and a welding fixing sleeve are provided on the tail welding component body, and circular grooves are provided on both sides of the welding fixing sleeve; a bolt is used to connect the tail movable plate and the tail welding component body, and an arc-shaped groove is provided on the tail welding component body, and a bolt is used to connect the arc-shaped groove and the tail movable plate;

[0006] Both mounting bases are equipped with telescopic cylindrical components that insert into circular slots;

[0007] The front end of the main body of the swing tail weldment is provided with a welding positioning block, which is connected to the up-and-down swing support assembly.

[0008] Preferably, the up-and-down swing support assembly includes a U-shaped groove, an arc-shaped rod is provided on the U-shaped groove, a connecting seat is slidably sleeved on the outer side of the arc-shaped rod, and arc-shaped springs connected to the upper and lower sides of the U-shaped groove are provided on both the top and bottom sides of the connecting seat. Bolt three connects the welding positioning block and the connecting seat.

[0009] Preferably, the welding positioning block is slidably connected to the connecting seat.

[0010] Preferably, the telescopic cylindrical assembly includes a guide rod disposed on a mounting base, a sliding sleeve slidably sleeved on the guide rod, and a hollow cylinder matching the guide rod disposed on the sliding sleeve, universal balls evenly disposed on the sliding sleeve that contact the welded fixing sleeve, and bolts connected to the guide rod disposed on the sliding sleeve.

[0011] Preferably, the hollow cylinder is provided with a first wear-resistant coating on its exterior, and the circular groove is provided with a second wear-resistant coating that is in contact with the first wear-resistant coating.

[0012] Preferably, both the mounting base and the U-shaped groove are provided with mounting screw holes.

[0013] This utility model provides an assembly device for a floor scrubber's tail swing assembly. Compared with the prior art, it has the following advantages:

[0014] 1. This floor scrubber swing assembly assembly equipment, by setting up a swing support component, allows the main body of the swing welded component to swing up and down on the hollow cylinder through the circular groove. The connecting seat can slide along the direction of the arc rod, thereby driving the extension and contraction of the upper and lower arc springs. This does not affect the up and down swing of the main body of the swing welded component. In addition, in conjunction with the tension spring on the spring hanging plate, it can further support the swing assembly, improve its service life, and occupy little space. It is highly practical. In this way, even if one of the tension springs or the arc springs is damaged, the up and down swing of the swing assembly can still be guaranteed.

[0015] 2. The floor scrubber tail assembly assembly equipment uses telescopic cylindrical components on both sides to allow the hollow cylinder to be inserted into the circular groove when installing bolt four. This allows bolt four to be directly installed onto the sliding sleeve without having to lift the supporting tail assembly with one hand, thus saving effort when installing bolt four and facilitating quick and labor-saving assembly of the tail assembly.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] See Figures 1-4 This utility model provides the following two technical solutions:

[0023] First embodiment: A floor scrubber swing assembly assembly equipment includes a swing welded body 1, a swing movable plate 6, and two mounting seats 5. The swing welded body 1 is provided with a spring hanging plate 2 and a welding fixing sleeve 3. A tension spring is connected to the spring hanging plate 2, which provides tension and swing torque for the brush swing. Circular grooves 4 are opened on both sides of the welding fixing sleeve 3. Bolt 7 is connected between the swing movable plate 6 and the swing welded body 1. An arc groove 8 is opened on the swing welded body 1. Bolt 9 is connected between the arc groove 8 and the swing movable plate 6. The swing movable plate 6 is used to install the brush. It swings left and right around the axis of bolt 7. When swinging, it moves on the arc groove 8 through bolt 9 to improve the stability when swinging.

[0024] Both mounting bases 5 are equipped with telescopic cylindrical components that are inserted into the circular grooves 4;

[0025] The front end of the main body 1 of the swing tail welding component is provided with a welding positioning block 10, which is connected to the upper and lower swing support assembly.

[0026] The swing support assembly includes a U-shaped groove 11, an arc-shaped rod 12 on the U-shaped groove 11, a connecting seat 13 slidably sleeved on the outer side of the arc-shaped rod 12, and arc-shaped springs 14 connected to the upper and lower sides of the U-shaped groove 11 on both the top and bottom sides of the connecting seat 13. A bolt 15 connects the welding positioning block 10 and the connecting seat 13. When the swing tail welded body 1 and the welding positioning block 10 swing up and down, the connecting seat 13 is driven by the bolt 15 to slide outside the arc-shaped rod 12 to extend and retract the arc-shaped springs 14, so as not to affect the swing tail welded body 1's up and down swing. In addition, in conjunction with the tension spring on the spring hanging plate 2, it can further support the swing tail assembly, improve its service life, and occupy little space, making it highly practical. In this way, even if one of the tension springs or the arc-shaped springs 14 is damaged, the swing tail assembly can continue to swing up and down.

[0027] The welding positioning block 10 is slidably connected to the connecting seat 13, which facilitates the positioning of the welding positioning block 10 on the connecting seat 13 when installing bolt 3 15.

[0028] The telescopic cylindrical assembly includes a guide rod 16 mounted on a mounting base 5. A sliding sleeve 17 is slidably sleeved on the guide rod 16, and a hollow cylinder 18 matching the guide rod 16 is provided on the sliding sleeve 17. That is, both the sliding sleeve 17 and the hollow cylinder 18 can slide on the guide rod 16. Universal balls 19 that contact the welded fixing sleeve 3 are evenly arranged on the sliding sleeve 17. The universal balls 19 can reduce the wear between them and the welded fixing sleeve 3 through rolling friction. Bolts 20 connected to the guide rod 16 are provided on the sliding sleeve 17 to fix the sliding sleeve 17.

[0029] The hollow cylinder 18 is provided with a wear-resistant coating 21 on its exterior, and a wear-resistant coating 22 in contact with the wear-resistant coating 21 is provided in the circular groove 4. This can improve wear resistance, reduce wear, and thus ensure the stability of the swing. Both the wear-resistant coating 21 and the wear-resistant coating 22 can be ceramic coatings.

[0030] The hollow cylinder 18 does not contact the end of the circular groove 4, so that the opposite side of the hollow cylinder 18 and the circular groove 4 will not be worn.

[0031] The second embodiment differs from the first embodiment in that both the mounting base 5 and the U-shaped groove 11 are provided with mounting screw holes for mounting the mounting base 5 and the U-shaped groove 11 onto the vehicle frame.

[0032] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0033] After the welding positioning block 10 and the connecting seat 13 are installed with bolts 15, pull the sliding sleeves 17 on both sides along the guide rod 16 until the universal ball bearing 19 contacts the welding fixing sleeve 3. At this time, the hollow cylinder 18 can be inserted into the circular groove 4. Then, bolts 20 are installed on the sliding sleeve 17 to connect it with the guide rod 16. There is no need to use one hand to install bolts 20 and the other hand to lift the support swing tail assembly.
