[0034] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.
[0035] As Figures 1 - 6As shown in the figure, the present utility model provides a crystal packaging structure, including a crystal 100, a reflective layer 200, a window piece 300 and an elastic member 400. The outside of the crystal 100 is coated with the reflective layer 200. The material of the reflective layer 200 is one of magnesium oxide, aluminum oxide and polytetrafluoroethylene, or a mixture of multiple of them. The method of coating the reflective layer 200 outside the crystal 100 and the material selection of the reflective layer 200 are prior arts in the field, and will not be specifically limited here. One end of the cylinder 1 is provided with a receiving portion 14, and the receiving portion 14 communicates with the inner cavity of the cylinder 1. The window piece 300 is arranged in the receiving portion 14 of the cylinder 1. The window piece 300 is made of glass, preferably a high-temperature resistant glass piece. The window piece 300 and the crystal 100 are connected by an optical coupling agent. The window piece 300 and the crystal 100 can be coupled by a coupling process in the prior art, and will not be specifically described here. The end cap 2 is arranged at the other end of the cylinder 1. Both ends of the elastic member 400 can respectively abut against the reflective layer 200 and the end cap 2. When the end cap 2 is fixedly connected to the cylinder 1, the elastic member 400 presses the crystal 100 tightly against the window piece 300 to prevent the packaged crystal 100 from moving. A clamping groove 131 is arranged on the inner side wall of the cylinder 1. The end cap 2 includes a cover plate 21 and a flange 22. The cover plate 21 is buckled at one end of the cylinder 1. The flange 22 is provided with a clamping hook 221, and the clamping hook 221 is used for clamping with the inner wall of the clamping groove 131. The connection between the end cap 2 and the cylinder 1 is realized by the clamping of the clamping hook 221 and the clamping groove 131. At the same time, the cover plate 21 of the end cap 2 presses the elastic member 400, and the elastic acting force of the elastic member 400 on the end cap 2 is borne by the clamping hook 221, so as to prevent the end cap 2 from moving axially and radially. Along the radial direction of the cylinder 1, a glue groove 20 is formed between the outer side wall of a part of the flange 22 and the inner side wall of the cylinder 1. The glue groove 20 is filled with a sealant to prevent the glue from penetrating into the inner cavity of the cylinder 1. Since the elastic acting force of the elastic member 400 is completely borne by the clamping hook 221 after the end cap 2 is clamped with the cylinder 1, the elastic acting force of the elastic member 400 cannot act on the glue, that is, the glue is not affected by external force, so as to slow down the aging speed, ensure the high-temperature resistant performance, and thus improve the service life of the crystal 100.
[0036] Specifically, please refer to Figures 1 - 3 and in combination with Figures 4 - 6As shown in the figure, the cylinder body 1 is provided with a laminated part 11, a stepped part 12 and a clamping part 13. The laminated part 11 and the clamping part 13 are connected by the stepped part 12. The thickness of the laminated part 11 is less than that of the stepped part 12, and the thickness of the stepped part 12 is less than that of the clamping part 13. The outer side wall of the flange 22 is attached to the positioning wall 121 of the stepped part 12. Since the thickness of the laminated part 11 is less than that of the stepped part 12, there is a gap between the outer side wall of the flange 22 and the laminated part 11 to form a glue groove 20. And by the positioning wall 121 of the stepped part 12 being attached to the outer side wall of the flange 22, it can also prevent the sealant from seeping into the inner cavity of the housing after injecting the glue. The clamping groove 131 is arranged on the clamping part 13. Specifically, the clamping groove 131 is arranged on the side of the clamping part 13 that cooperates with the flange 22, that is, the inner side of the clamping part 13. Thus, the hook 221 on the outer side of the flange 22 is clamped with the inner wall of the clamping groove 131 on the inner side of the clamping part 13. After the clamping is completed, under the elastic force of the elastic member 400, the hook 221 is pressed against the inner wall of the clamping groove 131. Thus, the end cover 2 cannot move away from the cylinder body 1 along the axial direction of the cylinder body 1, and by the positioning wall 121 of the stepped part 12 being attached to the outer side wall of the flange 22, the end cover 2 also cannot move along the radial direction of the cylinder body 1.
[0037] Furthermore, please refer to Figures 1 - 3 and in combination with Figures 4 - 6 As shown in the figure, the clamping part 13 is provided with a limiting protrusion 132. Specifically, the stepped part 12 and the clamping groove 131 together form the limiting protrusion 132. A limiting groove 223 is arranged on the outer side of the flange 22. Both the limiting protrusion 132 and the limiting groove 223 are arranged as annular structures, and their structural shapes are the same. When the hook 221 is clamped with the inner wall of the limiting groove 223, the limiting protrusion 132 is attached to the groove wall of the limiting groove 223. By arranging the limiting protrusion 132 and the limiting groove 223, after the end cover 2 is clamped with the cylinder body 1, the limiting protrusion 132 and the limiting groove 223 can further limit the end cover 2 from approaching the cylinder body 1 along the axial direction of the cylinder body 1, further preventing the end cover 2 from moving under the action of external force, thereby restricting the movement of the end cover 2 along the axial and radial directions of the cylinder body 1. During the glue injection process and the curing process of the glue, the end cover 2 will not move, thus ensuring airtightness. In addition, the cooperation of the limiting protrusion 132 and the limiting groove 223 also plays a role in labyrinth seal, preventing the glue from seeping out of the glue groove 20 into the inner cavity of the cylinder body 1.
[0038] Optionally, as Figure 5 shown in the figure, a chamfer 222 is arranged at the end of the hook 221. The chamfer 222 is arranged at the end of the hook 221 away from the cover plate 21. Please continue to refer to Figures 1 - 3As shown, during the clamping process of the end cover 2 and the cylinder 1, the end cover 2 gradually approaches the cylinder 1 along the axial direction of the cylinder 1, and the flange 22 of the end cover 2 gradually extends into the interior of the cylinder 1. Initially, the flange 22 maintains a certain interval with the rubber sandwiching portion 11, and then the chamfer 222 provided at the hook 221 contacts the clamping portion 13, and under the action of the chamfer 222, the hook 221 of the flange 22 undergoes elastic deformation toward the axis of the cylinder 1, and as the flange 22 continues to extend into the cylinder 1, the hook 221 reaches the clamping groove 131 and recovers and clamps in the clamping groove 131 under the elastic force, and at the same time, the flange 22 fits with the positioning wall 121 of the step portion 12, and the limiting protrusion 132 fits with the limiting groove 211 of the clamping portion 13, at which time the end cover 2 and the cylinder 1 are completely clamped and the end cover 2 cannot move along the axial or radial direction of the cylinder 1.
[0039] Furthermore, if Figure 3 As shown, the top of the glue sandwich portion 11 is spaced apart from the cover plate 21, and an annular groove-shaped glue injection port 10 is formed, and the glue injection port 10 is connected to the glue groove 20. By providing the glue injection port 10, it is convenient for the glue injection equipment or the glue injection tool to perform the glue injection operation. When the end cover 2 and the cylinder 1 are snap-fitted, the glue is injected into the glue groove 20 through the glue injection port 10, which is conducive to the colloid filling the glue groove 20 and preventing the colloid from overflowing or flowing to the outside of the cylinder 1, greatly improving the convenience of operation. Optionally, the sealant in this embodiment is selected from epoxy sealant, butyl sealant or polyurethane sealant, preferably epoxy sealant, to ensure good sealing performance and high temperature resistance.
[0040] Furthermore, if Figure 4 As shown, a groove 211 is provided on the end cap 2, and the groove 211 is located on the side of the end cap 2 away from the cylinder 1, that is, the groove 211 is provided on the outside of the end cap 2. By providing the groove 211, the thickness of the end cap 2 is reduced while ensuring the structural strength, so that the energy loss of the signal when passing through the end cap 2 is less, so as to improve the detection sensitivity of the crystal 100. Providing the groove 211 on the outside of the end cap 2 can ensure the flatness of the inner side of the end cap 2 to accommodate elastic members 400 of more structural forms. The elastic member 400 in this embodiment is a rubber member, a corrugated spring sheet or a silicone pad, which is not specifically limited here and is subject to actual engineering needs.
[0041] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the claims of the present invention.
