Detailed Description

Example 1. See fig. 1 a: the classroom multifunctional rack is an integrated application product, and comprises a front piece formed by connecting two equal-length side rods (111) and a cross rod a (112), a cross rod b (113) and other cross rods (114), and a rear piece formed by connecting two equal-length side rods (121) and a cross rod (122), wherein the upper ends of the rear piece side rods (121) are connected with the middle part of the front piece side rod (111) to form mutual support, a bottom fence (13) slightly higher than the ground is fixedly connected between the lower ends of the front piece and the rear piece, a classroom sanitary bucket (14) and a special cleaning bucket (15) are arranged on the bottom fence (13), and the multifunctional rack is stably erected on the ground. The solid board arranged between the left and right side rods (111) of the front piece (for writing for temporary notice and pasting paper contents, and is beneficial to wiping or clearing) shields various accessory sub-products hung at the rear side (such as a mop, a broom and the like at the middle upper part of the right side of fig. 1 a), so that students on the seat cannot see the solid board.

In the overall plan of the multifunctional shelf product, the water flowing out from the water tap (33) of the dual-purpose kettle is set to fall into the special washing barrel (15) right below after washing, so the cross bar a (112) is positioned at a proper height above the special washing barrel (15), and the cross bar b (113) is positioned near the lower part of the cross bar a (112) (obviously still above the special washing barrel (15)).

See FIGS. 3 d-e: the kettle body (2) can have two bilaterally symmetrical patterns, and the difference is that the vertical concave area (23) for assembling the water faucet is positioned, but the left and right parts of the kettle body (2) are designed without regard to the hanging structure (the head plate (41), the surrounding piece (5), the special-shaped pad (6) and the like) of the kettle body on the multifunctional frame. Except for a kettle main body (2), the design is the same as the previous dual-purpose kettle (see fig. 1c) in that the design is provided with a spray pipe (31), a sprinkling nozzle (32) and a faucet (33), the sprinkling nozzle (32) is assembled at the upper end of the spray pipe (31), the faucet (33) is assembled in a vertical concave area (23) at the side of the kettle, a carrying handle (21) and a water inlet (22) are arranged on the top surface of the kettle main body, and the water inlet (22) is provided with a cover (34).

See fig. 1 a-e: the original dual-purpose kettle is used for hanging the multifunctional rack cross rod a (112) through the picking piece (16), the picking piece (16) is long (about 15cm in actual products), particularly when the kettle is full, a hanging button (25) on the top surface of the kettle is connected with a front folding section (162) of the picking piece in a penetrating manner (see figure 1e specifically), and torque output by a base seat (161) at the rear end of the picking piece is quite large, so that the requirement on the structural strength of the joint of the cross rod a (112) and the side rod (111) is quite high; in addition, the picking piece (16) is generally a steel piece obtained by stamping, and because the picking piece is close to the hand of an operator and is not shielded, the hand can be pinched and scratched if people carelessly feel careless in use, and the safety hazard to a certain degree exists.

See FIGS. 2 f-g: a head plate (41) is extended from the side surface of the kettle body (2). See FIGS. 2 a-j: the enclosure (5) is a metal stamping part or a high-strength injection molding part, and is fixed (such as riveting or bonding and composite riveting) on the cross bar a (112) of the front part of the multifunctional frame, the middle part of the enclosure (5) is fixed on the flat middle plate (52) of the cross bar a (112) for convenience of fitting, and small plates (51) at two ends of the upper part are encircled towards one side of the middle plate (52) to form an upper opening (53) which is released at one side. The head plate (41) at the side of the kettle body (2) is inserted into the upper opening (53) of the enclosing piece, and the weight of the kettle is borne by the cross rod a (112) attached to the enclosing piece (5). Since the upper side of the cross rod a (112) slightly inclines in the space (along with the front piece of the multifunctional rack), the more important factor is that the head plate (41) is deviated to one side of the kettle main body (2), so the kettle is about to slide off the cross rod a (112), but is prevented by the upper opening (53) of the enclosing piece. Therefore, the kettle body (2) can be reliably hung on the cross rod a (112) by the enclosing piece (5).

Because the head plate (4) is deviated from one side of the upper part of the kettle body (2), if the head plate (41) is only used for hanging the cross rod a (112), although the kettle cannot fall, the kettle is naturally inclined in space due to the self weight, so that teachers and students are inconvenient to wash hands and the like, and the space stability is poor. Referring to fig. 2a and 4 a-b: the special-shaped pad (6) is fixed on the cross rod b (113), the cross rod b (113) is positioned below the position close to the cross rod a (112), the special-shaped pad (6) is aligned with the enclosure (5) in the middle, the space height of the cross rod b (113) and the special-shaped pad (6) corresponds to the space height of the lower part of the kettle main body (2), and the thickness of the special-shaped pad (6) in the horizontal direction enables the kettle main body (2) to be in an upright posture in space.

See fig. 2a, 2d, 2 f: the outer side of the special-shaped pad (6) is provided with a limit opening (62), the surface of the kettle body (2) below the head plate (41) is provided with a convex strip (24), the special-shaped pad limit opening (62) corresponds to the convex strip (24) of the kettle body in position, namely, the convex strip (24) is just put into the limit opening (62) when the kettle body (2) is hung on the upper opening (53) of the enclosing piece of the cross rod a. It is worth mentioning that: referring to fig. 2d and 2f in combination with fig. 4a-b, still because the head plate (41) is located on one side of the upper part of the kettle body (2), when the kettle is full of water, the kettle is affected by gravity (the amount of water filled in the kettle product reaches several kilograms), the raised line (24) of the kettle body is automatically inserted into the special-shaped pad limit (62), and the practical situation is that the more water in the kettle is, the tighter the kettle body is attached to the special-shaped pad (6) (the gravity of the kettle body and water is partially decomposed and converted into lateral pressure to the special-shaped pad (6), i.e. the side where the raised line (24) is attached to the limit (62) is tightly attached to each other), so that the kettle has a stable mechanism in the hanging of the cross bar, and the space stability is good and convenient to use; however, with the consumption of water discharging and hand washing of the faucet and even the absence of water in the kettle, the pressure of the side vertical surface of the kettle body (2) on the special-shaped pad (6) is gradually reduced to the minimum value (the whole weight of the empty kettle is hundreds of grams), and at the moment, the kettle is easy to take down from the upper opening (53) of the enclosing piece for refilling water.

The side plates (61) at the two ends of the special-shaped pad (6) embrace the vertical surface (namely the vertical surface of the head plate (41)) of one side of the kettle body (2), so that the upright posture of the kettle body (2) in the space is strengthened. (see fig. 2 i-j: the head plate (41) at the upper part of the picture is only in a splicing relationship with the upper opening (53), and the special-shaped pad (6) at the lower part is only butted against the kettle body (2) and is not adhered.)

Accordingly, even if the teachers and students need to manually discharge water by using the water tap to wash hands, the operation is not enough to disturb the hanging of the kettle main body (2) and the space standing state. If the whole multifunctional rack or the kettle main body (2) is impacted and vibrated accidentally, the kettle main body (2) can not fall off from the cross rod a (112) generally (except the situation that the multifunctional rack falls down when a violent earthquake occurs) because the depth of the upper opening (53) of the enclosing piece is proper, and the kettle main body (2) can automatically restore to the upright state under the gravity action of the kettle body and kettle water even if the posture of the kettle main body deviates.

The hanging connection of the dual-purpose kettle on the cross rod a (112) of the multifunctional rack, the holding of the special-shaped pad (6) to the kettle main body (2) and the maintenance of the space upright posture are few in involved parts, simple in structure, sufficient in effect and free of forced locking, and the operation of hanging the full water on the cross rod a (112) of the dual-purpose kettle and withdrawing the empty kettle for taking water is quite simple and convenient.

See fig. 3 a-e: if the head plate (41) is obtained without considering direct extension from the side surface of the kettle main body (2), the bottom interface piece (42) can be attached to the side surface of the kettle main body (2), and the head plate (41) extends from the bottom interface piece (42). The composite body of the head plate (41) and the bottom interface piece (42) is an upper card (4), and the upper card (4) can be obtained by stamping or stamping and welding or can be obtained by integral injection molding. The bottom piece (42) may be curved or planar, rather than curved as shown in fig. 3a-b, depending on the local configuration of the surface of the main body (2) to which it is attached.

Example 2. The enclosure (5) of example 1 was eliminated. A notch (1121) is punched on the upper side of the cross bar a (see especially figure 5d), and a kettle body head plate (41) is directly inserted into the notch (1121) on the upper side of the cross bar a, so that the dual-purpose kettle is reliably hung on the cross bar a (112).

Example 3. See FIGS. 5 d-e: constructing a sleeve opening (7), sinking the lower part of the sleeve opening (7) into a cavity of the cross rod a (pipe) from the notch (1121), bonding the opening surface layer of the sleeve opening (7) on the upper side surface of the cross rod a (112), and when the head plate (41) of the kettle body is inserted into the sleeve opening (7) (the lower bottom of the sleeve opening (7) can be closed or not), the dual-purpose kettle is reliably hung on the cross rod a (112), which is the same as the embodiment 2. In this embodiment, the appearance of the kettle body is simple, which is a preferred embodiment.

The following continues the description of the design:

see FIGS. 3 d-e: the kettle bodies (2) in the two figures are symmetrical, and if the kettle in figure 3d is called a kettle which is tied by a right hand, the kettle in figure 3e is called a kettle which is tied by a left hand. The water bottle is hung on the rear side of the front piece of the multifunctional rack in the classroom, a person to be washed can stand outside the left side of the multifunctional rack and can also stand outside the right side of the multifunctional rack, the position of the water tap (33) is convenient for water discharging operation, and the taking of the two water bottles (left and right hand systems) are determined according to the relative position relationship between the podium and the multifunctional rack in one classroom.

Secondly, the designed kettle main body (2) can be a cuboid as shown in the attached drawing, and also can be a cylinder or other shapes; the pot main body (2) can be not specially provided with the concave area (23), for example, a tap (33) is assembled at a certain position (directly perforated and communicated with the inside and the outside of the pot body) at the lower end of the side vertical surface of the pot main body (2), but the changes do not influence the relevant structural essence of the multifunctional frame cross rod hung on a certain side of the pot main body (2).

③ see fig. 6 a-c: if the upper side surface of the cross bar a (112) is deformed by pressing to form a shallow sinking groove (1122) similar to the cut (1121) of the cross bar a, the head plate (41) of the kettle body is shallowly connected with the shallow sinking groove (1122); or the upper side surface of the cross rod a (112) is processed into a front inclined plane, and the head plate (41) of the kettle body is arranged on the front inclined plane and cannot fall off automatically generally, but the hanging reliability is poor; or imitate the girth (5) of this design, make the back side of the horizontal pole a (112) extend upwards, the body headboard (41) of the kettle is blocked by extending the side upwards and still can be hung; each of the above situations is a near-net disadvantage of the present design.
