Description
Technical field
The utility model relates to the accessory on communication apparatus, railway equipment, Medical Devices, military industry equipment and intelligent grid equipment, refers to the panel accessory on a kind of industrial computer standard architecture, refers to especially a kind of spanner.
Background technology
Along with communication is established, railway, medical treatment, military project and the precise treatment day by day of Intelligent electric on-line apparatus and the raising of reliability, what bring is that requirement to aspects such as trip gear and spanner anti-misoperations improves day by day, reliability requirement improves.Existing spanner comprises wrench body and spanner bearing, and described spanner bearing and wrench body are rotationally connected, and also are provided with the buckle assembly between spanner bearing and wrench body, on this spanner bearing, also is connected with push rod; The spanner of this structure directly is rotationally connected due to spanner bearing and wrench body, less stable, in use in situation more of a specified duration, easily loosening, the person of being awkward uses, and existing buckle assembly has been realized the function of buckle by the elastic force of spring, spring can be used lost its bounce of a specified duration, causes service life shorter.
The utility model content
The deficiency existed for prior art, the purpose of this utility model is to provide the spanner that a kind of stability is higher and service life is longer.
The technical solution of the utility model is achieved in that a kind of spanner, comprise wrench body and spanner bearing, and also be provided with the buckle assembly between spanner bearing and wrench body, also be connected with push rod on this spanner bearing, also include external member, this external member is provided with the U-shaped groove, and the spanner bearing is positioned at this U-shaped groove, and spanner bearing and external member are rotationally connected, external member is fixedly connected with wrench body.
By adopting technique scheme, increased external member, improved the stability be connected between spanner bearing and wrench body, prevent that situation loosening between spanner bearing and wrench body from occurring, the convenient operation person uses.
The utility model further is set to: described buckle assembly comprises clamping block, one end of this clamping block is fixedly connected with wrench body, the other end is provided with the first barb, and there is gap between clamping block and wrench body, be provided with the second barb on described spanner bearing, the first barb and the second barb clamping arrange.
By adopting technique scheme, changed in existing spanner, use spring to complete the function of buckle, use the elastic force of clamping block self, spanner bearing and wrench body are fixed, avoided losing efficacy due to the elastic force of spring, cause reduce the service life of spanner, greatly improved service life.
The utility model also further is set to: described push rod is cylindric setting, and this push rod comprises linkage section and free segment, and this linkage section is connected with the spanner bearing, and the diameter of linkage section is greater than the diameter of free segment.
By adopting technique scheme, greatly increased the bonding strength of push rod and spanner bearing, in use, push rod is easy fracture not, and topology layout is more reasonable.
The accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, below will the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the utility model specific embodiment structural front view;
Fig. 2 is the utility model specific embodiment structure side view one;
Fig. 3 is the utility model specific embodiment structure side view two.
The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making under the creative work prerequisite the every other embodiment obtained, and all belong to the scope of the utility model protection.
As shown in Fig. 1-Fig. 3, the utility model discloses a kind of spanner, comprise wrench body 1 and spanner bearing 2, and also be provided with the buckle assembly between spanner bearing 2 and wrench body 1, also be connected with push rod 4 on this spanner bearing 2, in the utility model specific embodiment, also include external member 3, this external member 3 is provided with the U-shaped groove, spanner bearing 2 is positioned at this U-shaped groove, and spanner bearing 2 is rotationally connected with external member 3, external member 3 is fixedly connected with wrench body 1, wherein spanner bearing 2 and external member 3 are hinged by rotating shaft 6, the two ends of this rotating shaft 6 are individually fixed on wrench body 1, increased external member, improved the stability be connected between spanner bearing and wrench body, prevent that situation loosening between spanner bearing and wrench body from occurring, the convenient operation person uses.
In the utility model specific embodiment, described buckle assembly comprises clamping block 5, one end of this clamping block 5 is fixedly connected with wrench body 1, the other end is provided with the first barb 51, and there is gap 7 between clamping block 5 and wrench body 1, be provided with the second barb 21 on described spanner bearing 2, the first barb 51 and the second barb 21 clamping settings, wherein clamping block 5 tops also are provided with button 8, changed in existing spanner, use spring to complete the function of buckle, use the elastic force of clamping block self, spanner bearing and wrench body are fixed, avoided losing efficacy due to the elastic force of spring, cause reduce the service life of spanner, greatly improved service life.
In the utility model specific embodiment, described push rod 4 is cylindric setting, this push rod 4 comprises linkage section 41 and free segment 42, this linkage section 41 is connected with spanner bearing 2, and the diameter of linkage section 41 is greater than the diameter of free segment 42, greatly increased the bonding strength of push rod and spanner bearing, in use, push rod is easy fracture not, and topology layout is more reasonable.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
