Detailed Description
It should be noted that, in the case of no conflict, the embodiments and features of the embodiments of the present invention may be combined with each other.
As shown in fig. 1 and fig. 2, a pigtailed grating reflector includes a first core assembly 1 and a second core assembly 2 which are coaxially connected, where the first core assembly 1 includes a first core 11, a first core sleeve 12, a threaded pipe 13, and a first external thread sleeve 14 which are sequentially arranged from inside to outside; wherein the first core housing 12 is in interference fit with the first core 11, and the threaded pipe 13 provided with the external thread and the first external thread housing 14 provided with the internal thread are both in threaded connection with each other. The outer circular surface of the threaded pipe 13 comprises elastic sheets 15 which are axially distributed and convex and accommodating grooves 16 for accommodating the elastic sheets 15, the outer circular surface of the first core sleeve 12 is provided with slotted holes 17 which are circumferentially distributed and rectangular in shape, the first external thread sleeve 14 is provided with an unlocking mechanism 18 which is in rotary connection and matching with the first external thread sleeve, and the inner circular surface of the unlocking mechanism 18 comprises an annular groove 20 which is in rotary matching with the unlocking mechanism 18. The inner circle surface of the unlocking mechanism 18 is provided with an unlocking block 19, and the elastic sheet 15 and the unlocking block 19 are both positioned in the slotted hole 17.
During assembly, the first core 11 with the first core sleeve 12 is inserted into the threaded pipe 13 until the elastic piece 15 moves to the position of the receiving groove 16, and the elastic piece 15 is not reset into the receiving groove 16 by pressure, so that the installation of the first core 11 is completed.
When in detachment, the first external thread sleeve 14 is rotated, the unlocking block 19 is driven to move linearly through spiral movement, the unlocking block 19 presses the elastic piece 15 in the moving process, the elastic piece 15 moves into the accommodating groove 16, and therefore the first core body 11 and the first core sleeve 12 can be removed from the threaded pipe 13 in a whole.
Therefore, when the first core 11 is damaged, the whole pigtail grating reflector does not need to be replaced, and only the first core 11 needs to be replaced, so that the replacement cost is saved, and in addition, the elastic sheet 15 is controlled to move through the unlocking block 19, so that the operation is very convenient.
As shown in fig. 1 and 3, the second core assembly 2 further includes a second core 21, a second core sleeve 22, a clamping sleeve 23, and a second external thread sleeve 24, which are sequentially arranged from inside to outside. The second core sleeve 22 is sleeved on the second core body 21 in an interference manner, and the clamping sleeve is in threaded connection with the second external thread sleeve 24; the inner circumferential surface of the second externally threaded sleeve 24 is provided with an inclined surface, the clamping sleeve 23 comprises 4 circumferentially distributed clamping strips 25, a gap is arranged between every two adjacent clamping strips 25, and when the second externally threaded sleeve 24 is screwed relative to the clamping sleeve 23, the second externally threaded sleeve 24 resists the movement of the clamping strips 25 towards the second core sleeve 22 through the inclined surface, so that the clamping strips 25 clamp the second core sleeve 22.
In order to improve the contact surface between the clamping strip 25 and the second core sleeve 22, the inner side surface of the clamping strip 25 is an inclined surface, so that when the clamping strip 25 is deformed under a force, the inclined surface of the clamping strip 25 is changed into a straight surface, so that the clamping strip is in closer contact with the second core sleeve 22, and the connection strength is increased.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
