Abstract

An inner tube and outer tube connecting structure of a pool bottom brush handle comprises an elastic body, and is characterized in that the elastic body comprises two lateral rods and a supporting piece, wherein the lateral rods are arranged parallel to each other and are integrally formed, and the supporting piece can keep the two lateral rods propped open. The supporting piece is V-shaped, the lateral rods are connected at the two ends of the V shape of the supporting piece, and protrusions capable of extending out of an inner tube are formed on each lateral rod. The integrally formed structure is adopted for the lateral rods and the supporting piece, the two lateral rods can be kept at a propped open state always under the effect of the elastic force of the supporting piece, and further, the protrusions are further formed on the lateral rods, the protrusions can be matched with through holes formed in the inner tube in an inserted mode, and efficient fit between the connecting structure and the inner tube can be achieved in the assembling process. The installation is simple and convenient, and positioning is accurate. Meanwhile, the protrusions exposed out of the inner tube can be in contact fit with an outer tube, and the reliable connection between the inner tube and the outer tube is guaranteed.

Description

The inner and outer pipes linkage structure of tank bottom brush handle

Technical field

The utility model relates to a kind of inner and outer pipes linkage structure of tank bottom brush handle.

Background technique

In the prior art, various equipment for the cleaning pond are arranged, such as cleaning brush at the bottom of the cleaning brush, particularly pond at the bottom of cleaning machine and all kinds of pond at the bottom of the various automatic ponds because structure is small and exquisite, simple, easy to carry, multiplex at the bottom of manual pond cleaning.

The handle of cleaning brush generally all includes inner and outer tubes at the bottom of traditional pond, in order to guarantee the connection between the inner and outer tubes, usually, all need to linkage structure be set between inner and outer pipes and realize, the linkage structure of using at present operates comparatively complicated, in case after connection is installed, need bimanualness could realize the separation of inner and outer pipes, and high to the requirement of strength of inner and outer pipes, manufacture cost and the technology difficulty of increase material await to do further improvement.

The model utility content

Technical problem to be solved in the utility model is that a kind of more convenient inner and outer pipes linkage structure that is used for the tank bottom brush handle that mounts and dismounts is provided for above-mentioned prior art present situation.

The utility model solves the problems of the technologies described above the technological scheme that adopts: a kind of inner and outer pipes linkage structure of tank bottom brush handle, include the elastic body, it is characterized in that: the supporting element that described elastic body includes integrated two side levers that mutually be arranged in parallel and can keep two described side levers to strut, described supporting element is V-shaped, the V-arrangement two ends of this supporting element are connected with respectively described side lever, and, form protractile projection outside described inner tube on each described side lever.

In order to improve the reliability of connection, and for convenience detach, as preferably, be respectively arranged with two up and down spaced apart the first projection and the second projections on each described side lever, correspondingly, offer the first through hole and second through hole that can supply respectively described the first projection and the second projection to expose on the sidewall of described inner tube.

In order to prevent linkage structure rocking in inner tube, as preferably, described supporting element also forms the card division of C shape at the top of V-arrangement, and the two ends of described C shape card division offset with the madial wall of inner tube respectively.So, after connection set is put into inner tube, the two ends of C shape card division offset with the madial wall of inner tube respectively, side lever then struts under the elastic reaction of supporting element, projection on the side lever is then inserted respectively in the corresponding through hole, guarantee the reliable location of linkage structure in inner tube, avoided linkage structure rocking in inner tube.

Compared with prior art, the utility model has the advantage of: side lever and supporting element adopt integrated formed structure, two side levers can remain softened state under the resilient force of strut, and, on side lever, also form projection, projection can with inner tube on the inserting of through hole phase, can realize the quick cooperation of linkage structure and inner tube in when assembling, so that installation is more simple and convenient, accurate positioning; And the projection that exposes to inner tube can realize and the cooperation that contacts of outward appearance, guarantees the reliable connection of inner and outer pipes.

Description of drawings

Fig. 1 is the utility model embodiment's linkage structure schematic representation.

Fig. 2 is linkage structure sectional view shown in Figure 1.

Fig. 3 is linkage structure three-dimensional exploded view shown in Figure 1.

Embodiment

Embodiment is described in further detail the utility model below in conjunction with accompanying drawing.

Such as Fig. 1～shown in Figure 3, present embodiment discloses a kind of inner and outer pipes linkage structure of tank bottom brush handle, this linkage structure includes an elastic body, the supporting element 2 that this elastic body has two side levers that mutually be arranged in parallel 1 and can keep two side levers 1 to strut all the time, wherein, supporting element 2 is V-shaped, the V-arrangement two ends of this supporting element 2 connect respectively an end of two side levers 1, supporting element 2 also forms the card division 21 of C shape at the top of V-arrangement, the two ends of C shape card division 21 can come closer under external force, and offset with the madial wall of inner tube 3 respectively.

Be respectively arranged with two up and down spaced apart the first projection the 11 and second projections 12 on each side lever 1, correspondingly, offer the first through hole 31 and second through hole 32 that can expose for the first projection the 11 and second projection 12 respectively on the sidewall of inner tube 3, referring to Fig. 3;

During installation, pinch two side levers 1 of elastic body with hand, so that mutually close between two side levers 1, then the elastic body is inserted in the inner tube 3, so that the projection of first on the side lever 1 the 11 and second projection 12 is aimed at respectively the first through hole 31 and second through hole 32 of inner tube 3, after the relieving, side lever 1 struts under the elastic-restoring force effect of supporting element 2, the first projection the 11 and second projection 12 snaps in respectively in the first through hole 31 and the second through

hole

32,21 two ends, C shape card division of the V-arrangement of supporting element 2 bottom then offset with the madial wall of inner tube 3, with outer tube sleeve outside inner tube 3, exposing to the projection of first outside the inner tube 3 the 11 and second 12 of projections can offset with the madial wall of outer tube, thereby realizes interconnecting of inner and outer pipes;

During dismounting, finger is pinned two second protruding 12 positions of relatively establishing that are positioned at side lever 1 below, make it mutually close, two side levers 1 clamp thereupon, so, in second protruding 12 indentations the second through hole 32, the first projection 11 is under the drive of side lever 1 also thereupon in indentation the first through hole 31, operator's voucher hand just can be realized the separation of inner and outer pipes, operates more laborsaving, convenience, and it is more convenient to dismantle.
