Abstract

The utility model discloses a cable self-adaptive locking structure for a submersible pump, which comprises a pump body and a handle arranged on the pump body, wherein a clamping hole for clamping a limiting cable wire is arranged between the pump body and the handle. The utility model designs seven circular arc grooves in the clamping holes on the handle, forms tooth shapes among the circular arc grooves, has simple processing and strong reliability, fully considers the situation of the rubber sheath after being pressed, has good locking effect, and can effectively form locking when the matched is loose, the tooth tops penetrate into the rubber sheath, and the rubber of the rubber sheath can penetrate into the root circle when the matched is tight, thereby releasing the pressing force and avoiding the damage to the handle possibly caused by over-tightening.

Description

Cable self-adaptive locking structure for submersible pump

Technical Field

The utility model relates to a pump body structure, in particular to a cable self-adaptive locking structure for a submersible pump.

Background

On the immersible pump, in order to protect cable conductor joint, after the one section of cable conductor was sheathe in the rubber sheath, can be fixed on the handle, as shown in fig. 1, form the clamp hole 3 of cable conductor between the pump body 1 and the handle 2, the clamp hole is the unthreaded hole, presss from both sides the cable conductor that the clamp is downthehole to press from both sides tightly behind the rubber sheath of cover and carries out spacingly.

However, because the thickness of the cables of different types is different, the types of the matched rubber sheaths are limited, and the rubber sheaths fixed by the handle are sometimes loose and unreliable; the handle can be damaged when the cable is too tight, and the cable can not be clamped for limiting after the cable is too loose.

Disclosure of utility model

In order to solve the technical problems, the utility model designs a cable self-adaptive locking structure for a submersible pump.

The utility model adopts the following technical scheme:

The utility model provides a cable self-adaptation locking structure for immersible pump, includes the handle of installing on the pump body and the pump body, is provided with the clamp hole that is used for pressing from both sides tight spacing cable conductor between the pump body and the handle, the indent is provided with a plurality of inner groovings on the handle of the upper end in the clamp hole, forms the profile of tooth between the adjacent inner groovings.

Preferably, the depth of the plurality of inner grooves is gradually increased from two sides to the middle.

Preferably, the depth of the plurality of inner grooves is 0-3mm, respectively.

Preferably, the plurality of inner grooves are arc grooves with arc sections respectively.

Preferably, the pump body and the handle are fastened by bolts.

The beneficial effects of the utility model are as follows: the utility model designs 7 circular arc grooves in the clamping holes on the handle, forms tooth shapes among the circular arc grooves, has simple processing and strong reliability, fully considers the situation of the rubber sheath after being pressed, has good locking effect, and can effectively form locking when the matched is loose, the tooth tops of the rubber sheath penetrate into the tooth root circle when the matched is loose, and the rubber of the rubber sheath can penetrate into the tooth root circle to release the pressing force, thereby avoiding the possible damage to the handle when the matched is loose.

FIG. 2 is a schematic view of a construction of the present utility model;

In the figure: 1. pump body, 2, handle, 3, clamp hole.

Detailed Description

The technical scheme of the utility model is further specifically described by the following specific embodiments with reference to the accompanying drawings:

Examples: as shown in fig. 2, the cable self-adaptive locking structure for the submersible pump comprises a pump body 1 and a handle 2 arranged on the pump body, wherein a clamping hole 3 for clamping a limiting cable line is formed between the pump body and the handle, seven inner grooves are formed in the handle at the inner upper end of the clamping hole in a concave manner, and tooth shapes are formed between the adjacent inner grooves.

The depth of the seven inner grooves is gradually increased from two sides to the middle. The depth of the seven inner grooves is 0-3mm respectively. The seven inner grooves are arc grooves with arc sections respectively. The pump body and the handle are fastened through bolts.

The utility model designs seven circular arc grooves in the clamping holes on the handle, forms tooth shapes among the circular arc grooves, has simple processing and strong reliability, fully considers the situation of the rubber sheath after being pressed, has good locking effect, and can effectively form locking when the matched is loose, the tooth tops penetrate into the rubber sheath, and the rubber of the rubber sheath can penetrate into the root circle when the matched is tight, thereby releasing the pressing force and avoiding the damage to the handle possibly caused by over-tightening.

The above-described embodiment is only a preferred embodiment of the present utility model, and is not limited in any way, and other variations and modifications may be made without departing from the technical aspects set forth in the claims.
