Description

A kind of totally-enclosed suspender
Technical field
The present invention relates to five metals suspender field, specifically, be a kind of totally-enclosed suspender.
Background technology
Suspender is as a kind of instrument, and use frequency in daily life is the highest, and especially in lifting work, suspender is requisite a kind of instrument, during use, need to be suspended on suspender by suspended object.Suspender of the prior art, substantially can meet lifting requirements of one's work, for security consideration, a lot of suspenders are provided with tongue piece at hooking slits, be used for preventing suspended object from coming off from suspender, but tongue piece of the prior art uses thin structure often, if the emergency of meeting, suspended object has the possibility broken by tongue piece, and tongue piece is easily deformed, so that the service life of suspender reduces.
Summary of the invention
It is an object of the invention to provide a kind of totally enclosed suspender, its simple in construction, easy to operate, employing bumping post will be linked up with totally-enclosed, solve the problems referred to above.
The present invention is achieved through the following technical solutions: a kind of totally-enclosed suspender, the connecting portion including hoist cable, being suspended on hoist cable and fix the hook being connected with connecting portion, and the opening fixed operating sleeve cylinder of described hook, be slidably installed in sleeve bumping post.
Further, the bottom thread of described sleeve connects baffle plate.
Further, it is fixedly connected with spring at described baffle plate towards one end end face of sleeve inner.
Further, the free end of described spring is fixing with the bottom of bumping post is connected.
Further, the opening part of described upper cartridge is provided with limited step.
Further, the bottom of described bumping post is provided with the positioning step corresponding with limited step.
The present invention compared with prior art, has the following advantages and beneficial effect:
(1) present invention uses at butt crack opening part fixed operating sleeve cylinder, and in sleeve sliding connection bumping post, utilize bumping post by hooking slits bumping post, hook and bumping post form 360 degree and entirely block, prevent suspended object from coming off, so that the safety that the present invention is in use is greatly improved;
(2) present invention connects in the bottom thread of sleeve the baffle plate of band spring, and in order to by the sealed bottom of sleeve, anti-stopper posts comes off from sleeve bottom, and then enhances the practicality of the present invention;
(3) in the present invention, the free end of spring is fixing with the bottom of bumping post to be connected, the state arranging spring is compressive state, now spring will apply an elastic acting force to bumping post, in order to bumping post is withstood, entirely block so that bumping post and hook realize 360 degree, prevent suspended object from coming off, and then increase practicality and the safety of the present invention;
(4) present invention is provided with limited step at the opening part of upper cartridge; and the bottom of bumping post is provided with the positioning step corresponding with limited step; when bumping post stretch out under the effect of spring active force sleeve reach certain length time; positioning step contacts with limited step; bumping post is avoided to continue to stretch out sleeve and drop; thus protect bumping post not fall off, strengthen practicality and the safety of the present invention.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention;
Wherein 1 hoist cable, 2 connecting portions, 3 hooks, 4 sleeves, 5 bumping posts, 6 baffle plates, 7 springs, 41 limited steps, 42 positioning steps.
Detailed description of the invention
Below in conjunction with embodiment, the present invention is described in further detail, but embodiments of the present invention are not limited to this.
Embodiment:
As shown in Figure 1, in the present embodiment, a kind of totally-enclosed suspender, the hook 3 being connected is fixed with connecting portion including hoist cable 1, the connecting portion 2 that is suspended on hoist cable 1, fixed operating sleeve cylinder 4 on the sidewall of hook 3, the equal opening in sleeve 4 two ends is through, and sleeve 4 is away from the threaded baffle plate in the bottom linking up with 3 openings 6, and baffle plate 6 is at the spring 7 connecting compression fixing on the end face in sleeve;Be slidably installed in sleeve bumping post 5, and the free end of spring 7 is fixing with the bottom of bumping post 5 to be connected;The bottom of bumping post 5 is provided with positioning step 42, and the opening part in the upper end of sleeve 4 is provided with limited step 41.
During use, bumping post 5 only need to be pressed into sleeve 4 by user, links up with 3 openings and opens, and suspended object can be suspended on hook 3 by user;Release bumping post 5 subsequently, bumping post 5 is under the elastic force effect of spring 7, by the slide along sleeve 4, and stretches out the upper surface of sleeve 4, and is sealed by the opening of hook 3, it is achieved 360 degree of general blockade;Owing to spring 7 is compression spring, therefore utilize the elastic force effect of spring 7, the bumping post 5 in the present invention can be made to realize auto-lock function in its natural state.
As the preferred forms of the present embodiment, linking up with for arc of hook 3, sleeve 4 is arc sleeve, and bumping post 5 is arc bumping post, and the arc length of sleeve 4 is slightly smaller than the arc length of bumping post 5.
The above, be only presently preferred embodiments of the present invention, and the present invention not does any pro forma restriction, every above example is made according to the technical spirit of the present invention any simple modification, equivalent variations, within each falling within protection scope of the present invention.
