Description

Technical field

The proposed utility model relates to the field of pumping equipment and tools, in particular, to the designs of handles or handles for carrying equipment on which they are installed.

State of the art

The handle of a portable pump is known from the prior art (see information source CN 201723454 U, 01/26/2011), made in the form of a single part containing surfaces that form a housing having, on one side, an open cavity for accommodating elements of the pump terminal assembly, moreover, one of the surfaces of the housing contains a section protruding relative to the housing, forming a visor for carrying the pump.

The known handle has a significant drawback, namely, it does not provide sufficient bearing capacity of the handle while maintaining the overall dimensions of the pump due to the absence in its design, in particular, of a metal plate and scarves.

Utility Model Disclosure

The technical result, which the proposed technical solution is aimed at, is to provide the possibility of using a portable handle while maintaining its bearing capacity without increasing the dimensions of the pump unit.

This problem is solved by creating a portable pump handle, made in the form of a single part, containing surfaces that form a casing, having only on one side an open cavity for accommodating elements of the pump terminal assembly, one of the casing surfaces containing a portion protruding relative to the casing, forming a visor for carrying the pump, and according to a utility model, the housing has side gussets with holes, which, like the protruding section, are made of the material of the housing part, in addition, the soldering section is oriented towards the pump inlet and contains a metal strip integrated into it, placed in the material of the protruding section from its inner side, the edges of the metal strip being bent at right angles to form two straight sections, each of which has openings and is adjacent to the nearest kerchief on its inner side, and the holes in these sections of the metal strip are coaxial with the holes in the scarves, in addition, the housing has inside the cavity made of material of the housing for Details vertical cylindrical recesses with holes to ensure fixation of the housing relative to the pump terminal block.

Thus, the claimed technical solution with its entire set of essential features allows us to provide the bearing capacity of the handle of the pump unit without increasing its overall dimensions.

Brief Description of the Drawings

In FIG. 1 shows a General view of the pump unit with the proposed handle.

In FIG. 2 shows a general view of the handle of the pump unit.

Utility Model Implementation

As shown in FIG. 1 pump unit (1) contains a housing (2) of a special shape and design, which is also a handle (or handle). That is, the handle is a single housing part and contains a housing (2), which combines two functions: a carrier, like a handle, and a protective one, like a cover for a terminal box. Moreover, the elements of a single part are made so that their constituent parts provide the structural strength of the handle and its rigid attachment to the pump elements. The part for which the pump is carried is a visor (3) or a region protruding in relation to the housing (2). Moreover, the protruding section is oriented towards the inlet of the pump (see Fig. 1).

This handle is designed for pumps, which are surface self-priming centrifugal pumps with one impeller and with a cast iron housing. The pump and motor are combined in a common design. At the top of the engine is a terminal box for the capacitor and wire connections (Fig. 1).

Pumps are designed for pumping clean water. Installed outside the pumped medium (on the surface). The pump part has an inlet pipe for connecting a suction pipe and an outlet pipe for connecting a pressure (supply) pipe.

The pump contains a terminal box, the cover of which is simultaneously a handle (handle) for transferring the pump.

The case (2), which is the terminal box cover, has a part protruding 3-4 cm forward (see Fig. 2). Thereby a visor is formed, which you can grasp with your fingers. This visor or protruding part (3) is additionally strengthened by a metal strip integrated into this visor (protruding part), recessed into the housing from the inside, and side “scarves” (4) with symmetrical fixation by screws in horizontal position. In the rear part of the case on its sides there are decorative circles repeating in shape the capacitor located under the case.

As seen in FIG. 2, the handle of the portable pump is made in the form of a single part (for example, by molding from plastic material) containing surfaces that form the body (2). The case is made of a polymeric material (plastic or materials based on it). The housing is designed so that only on one side has an open cavity for placement of elements of the pump terminal block in it. Essentially, the body is a box, the cavity of which is formed by solid walls (two longitudinal walls, two transverse and upper wall). One of the surfaces of the body part contains a forward-facing section (3) relative to the body, made of material of the body part, in addition, the forward-facing section contains an integrated metal strip (4) located in the material of the protruding section from its inner side, and side scarves (5) adjacent to the corresponding surfaces of the casing and made of the material of the casing part, the edges of the metal strip being bent at right angles to form two straight sections, each of which has holes and is adjacent to the nearest scarf on its inner side, and the holes in these sections of the metal strip are coaxial with holes (6) on the scarves, in addition, the body part has vertical cylindrical recesses (7) inside the cavity with holes made of the material of the body part to ensure the fixation of the housing parts relative to the pump terminal block.

The metal strip is integrated into the material of the protruding part, for example by thermal heating.

Vertical cylindrical recesses (7) represent wells with through holes for placement of rods of fixing bolts in them. The upper outer part of these wells perceives the load from the caps of the fixing bolts.

The claimed handle is a single part, all the elements of this part provide the ability to achieve the claimed technical result, namely, the carrying capacity of the handle of the pump unit without increasing its overall dimensions.

So, all the elements of the handle are made on the basis of a given overall dimension of the terminal box so as not to go beyond the main components of the pump. Moreover, the presence of surfaces that make up a single body part, the presence of a metal plate, kerchiefs and vertical cylindrical recesses with holes, provide a high bearing capacity of the handle while maintaining the overall dimensions of the pump.

Side holes (6) in kerchiefs and a metal strip are also necessary for fastening this handle relative to the pump elements.

Claims (1)

The handle of a portable pump, made in the form of a single part containing surfaces that form a housing having, on one side, an open cavity for accommodating elements of the pump terminal assembly, one of the housing surfaces comprising a portion protruding relative to the housing, forming a visor for carrying the pump characterized in that the housing has lateral scarves with holes, which, like the protruding section, are made of material of the body part, in addition, the protruding section is oriented towards the inlet pump and contains an integrated metal strip located in the material of the protruding section from its inner side, and the edges of the metal strip are bent at right angles to form two straight sections, each of which has openings and is adjacent to the nearest scarf on its inner side moreover, the holes in these sections of the metal strip are aligned with the holes in the scarves, in addition, the housing has vertical cylindrical recesses made of the material of the housing part inside the cavity with holes for fixing the housing relative to the terminal of the pump assembly.
