Detailed Description
With reference to fig. 1 to 6, the syringe protection device includes a protection outer cylinder 1, a protection inner cylinder 2 and a compression spring 3;
one end of the protective inner cylinder 2 is symmetrically provided with two splayed elastic sheets 4 about an axial core of the protective inner cylinder 2, the splayed ends of the elastic sheets 4 are connected with the protective inner cylinder 2, the other end of the protective inner cylinder 2 is provided with a first baffle ring 5, the diameter of the first baffle ring 5 is larger than that of the protective inner cylinder 2, the first baffle ring 5 is connected with the protective inner cylinder 2 through a first baffle 6 vertical to the protective inner cylinder 2, a syringe 7 needle tube penetrates into the protective inner cylinder 2, one end of the needle tube penetrates out of one end of the elastic sheets 4, a plurality of needle tube limiting protruding blocks 8 protruding towards the center are arranged in the first baffle ring 5, and the needle tube limiting protruding blocks 8 abut against one end of the syringe needle tube;
a second baffle ring 9 is arranged at one end of the protective outer cylinder 1, the diameter of the second baffle ring 9 is larger than that of the protective outer cylinder 1, the second baffle ring 9 is connected with the protective outer cylinder 1 through a second baffle plate 10 perpendicular to the protective outer cylinder 1, the protective outer cylinder 1 is sleeved outside the protective inner cylinder 2, the compression spring 3 is sleeved outside the protective inner cylinder 2, and two ends of the compression spring are respectively abutted against the first baffle plate 6 and the second baffle plate 10;
the outer side of the protection inner cylinder 2 is provided with at least two main chutes 11, one ends of the main chutes 11, which are close to the first baffle 6, are respectively provided with a chute 12, the end part of the chute 12 is provided with a secondary chute 13 which is parallel to the main chute 11, the included angle between the chute 12 and the secondary chute 13 is 45 degrees, and a sliding block 14 which can slide in the main chute 11, the chute 12 and the secondary chute 13 is arranged in the protection outer cylinder 1.
Still be equipped with two pterygoid lamina 15 on the second baffle 10, pterygoid lamina 15 is perpendicular with protection urceolus 1, is equipped with a plurality of antislip strips 16 on the pterygoid lamina 15 for not only can make things convenient for handheld work, the protective effect is better moreover.
The protective outer cylinder 1 is provided with two symmetrically arranged locking components, each locking component comprises a through groove 17 penetrating through the side wall of the protective outer cylinder 1, a locking sheet 18 which is arranged on the protective outer cylinder 1 and penetrates into the protective outer cylinder through the through groove 17, the protective inner cylinder 2 is provided with an upper clamping groove 19 which is matched with the upper limit position of the locking sheet 18 in a sliding way and is recessed inwards, and a lower clamping groove 20 which is matched with the lower limit position of the locking sheet 18 in a sliding way, so that after the needle head is received in the protective outer cylinder 1, the protective outer cylinder 1 slides to the lower limit position of the protective inner cylinder 2, the locking sheet 18 is clamped in the lower clamping groove 20, the phenomenon that the needle head stretches out due to mistaken pressing can be avoided, the protective effect of the device is further enhanced, when the needle head stretches out of the protective outer cylinder 1, although the sliding block 14 is abutted to the secondary sliding groove 13 due to, but the locking stabilization effect of the device can be further enhanced by adding the structure that the locking sheet 18 is clamped in the upper clamping groove 19, so that the syringe 7 is safer when in use.
The outside of shell fragment 4 all is equipped with a lug 21, be equipped with one on the protection urceolus 1 with lug 21 complex cooperation groove 22, because two shell fragments 4 can realize spacing to syringe 7, and when having the protective sheath on the syringe needle of syringe 7, also can be through making two shell fragments 4 butt on the protective sheath, thereby avoid droing of protective sheath, and when setting up lug 21 on shell fragment 4, thereby can realize spacing to shell fragment 4, prevent that shell fragment 4 from taking place too big deformation, so that when losing the effect, can in time discover through the friction between lug 21 and the protection urceolus 1.
One end ring that protection urceolus 1 deviates from second fender ring 9 is equipped with a plurality of extension protecting pieces 23 towards the slope of protection urceolus 1 center, because the transparent plastic who protection urceolus 1 and protection inner tube 2 all adopt makes, consequently can be through the difference that has the clearance with the tip formation of protection urceolus 1, and then the position of coming better observation syringe needle, when the syringe needle slowly shifts out the protection urceolus, can perceive more easily.
The working principle of the invention is as follows: when the needle of the syringe 7 needs to be retracted into the protective outer barrel 1, one end of a locking piece 18 clamped into the upper clamping groove 19 is firstly away from the upper clamping groove 19, so that the compression spring 3 is compressed, the slide block 14 clamped in the secondary slide groove 13 enters the main slide groove 11 along the passage of the secondary slide groove 13, the chute 12 and the main slide groove 11, at the moment, the slide block 14 is limited in the secondary slide groove 13, the chute 12 and the main slide groove 11, therefore, the protective outer barrel 1 can rotate at a small angle relative to the protective inner barrel 2, until the slide block 14 slides to the end part of the main slide groove 11, the compression spring 3 is blocked when being compressed, the compression spring 3 is released, at the moment, the syringe 7 can move relative to the protective outer barrel 1 along with the protective inner barrel 2, the needle of the syringe 7 is retracted into the protective outer barrel 1, until the slide block 14 can slide to the other end part of the main slide groove 11 under the action of elastic recovery deformation of, and the locking sheet 18 can be clamped into the lower clamping groove 20 to realize auxiliary locking, so that the needle head of the syringe 7 is protected, and the safety is better.
Similarly, when the needle head needs to be moved out of the protection outer barrel 1, one end of the locking piece 18 clamped in the lower clamping groove 20 can be firstly far away from the lower clamping groove 20, the compression spring 3 is compressed until the sliding block 14 slides to the end part of the main sliding groove 11, and then the protection outer barrel 1 rotates relative to the protection inner barrel 2, so that the sliding block 14 enters the secondary sliding groove 13 along the inclined groove 12, and then the sliding block abuts against the secondary sliding groove 13 under the action of the compression spring 3, and the locking piece 18 is locked in the upper clamping groove 19.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
