[0002] The activated ions (such as doped rare earth elements or transition metal ions) inside the crystal block can be excited to the excited state after being excited by external energy, and can efficiently convert the energy provided by the outside world into laser energy, thereby spontaneously emitting laser.
[0003] The crystal block generates heat when generating laser, in order to maintain the appropriate temperature range, the crystal block needs to be set in the flowing cooling liquid, and the cooling liquid is restrained by the shell, the sealing ring and the crystal pressure block. The shell is provided with a perforation, the crystal block is arranged in the perforation, and the cooling liquid flow is arranged between the inner wall of the perforation and the crystal block. The sealing ring is sleeved on the crystal block and can abut against the end face of the perforation, so as to prevent the cooling liquid from flowing out. The crystal pressure block can be fixedly connected to the shell, so as to fix the sealing ring. However, in order to facilitate the installation of the crystal block, the crystal pressure block and the crystal block are installed in the form of gap fit, so that the return light can pass through the gap between the two and irradiate the sealing ring in large quantities, resulting in the phenomenon that the service life of the sealing ring is short and the damage frequency is high. The laser needs to be disassembled and the sealing ring needs to be replaced many times, which increases the maintenance cost and the maintenance frequency, and also increases the possibility of damage of the laser.
[0004] Therefore, there is an urgent need for a crystal pressure block and a laser to solve the above technical problems. UTILITY MODEL CONTENTS
[0005] One purpose of the utility model is to provide a crystal pressure block, which can prolong the service life of the sealing ring and reduce the replacement frequency of the sealing ring.
[0006] To achieve this purpose, the utility model adopts the following technical scheme:
[0007] The crystal pressure block comprises a support part and an elastic part, the support part is provided with a first perforation penetrating along a preset first direction, one end of the elastic part is connected to the inner wall of the first perforation and is configured as a connecting end, the other end of the elastic part is configured as an abutting end, and the elastic part can elastically deform to move the abutting end towards the direction close to the connecting end, and
[0008] When the elastic part is in elastic deformation, the abutting end can abut against the crystal block to block the return light, so as to reduce the irradiation of the return light on the sealing ring.
[0009] Preferably, the inner wall of the first through hole is provided with at least two elastic portions, and the abutting ends of all the elastic portions define an installation space for penetrating the crystal block.

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.
[0034] The following is based on the appendix Figure 1 To be continued Figure 5 This invention introduces the crystal clamp 4 and the laser provided by this utility model. It should be noted that, as... Figure 1As shown, in this embodiment, besides the crystal clamping block 4, the laser also includes a housing 1, a crystal block 2, and a sealing ring 3. The housing 1 has a mounting hole. The crystal block 2 passes through the mounting hole along a predetermined first direction (as shown by the X-axis in the figure), with its end located outside the mounting hole. The sealing ring 3 and the crystal clamping block 4 are fitted onto the end of the crystal block 2. The crystal clamping block 4 is fixedly connected to the housing 1 and seals the sealing ring 3 against the housing 1. A space for coolant flow is formed between the housing 1, the crystal block 2, and the sealing ring 3. When the coolant flows through, it absorbs heat from the crystal block 2, thereby maintaining the crystal block 2 at a suitable operating temperature.
[0035] like Figures 1 to 3 As shown, in this embodiment, the crystal block 4 includes a support portion 41 and an elastic portion 42. The support portion 41 is fixedly connected to the housing 1, while the elastic portion 42 abuts the sealing ring 3 against the housing 1 along a predetermined first direction, thereby sealing the housing 1 and the crystal block 2 to prevent coolant leakage. The support portion 41 has a first through-hole along the predetermined first direction, through which the crystal block 2 can pass into the mounting hole of the housing 1, with the end of the crystal block 2 located on the outside of the crystal block 4. One end of the elastic portion 42 is connected to the inner wall of the first through-hole and is defined as the connecting end 421, while the other end of the elastic portion 42 abuts against the crystal block 2 and is defined as the abutting end 422. When the crystal block 2 passes through the first through-hole, the elastic portion 42 is compressed by the crystal block 2 and undergoes elastic deformation, causing the abutting end 422 to move towards the connecting end 421. When the elastic part 42 is in elastic deformation, the abutting end 422 can abut against the crystal block 2, thereby blocking the reflected light generated by the laser and reducing the irradiation of the sealing ring 3 by the reflected light.
[0036] The elastic part 42 of the crystal clamping block 4 can be compressed and deformed, thus avoiding negative impacts on the installation of the crystal and preventing damage to the crystal. Simultaneously, this compression deformation is an elastic deformation, allowing the elastic part 42 to abut against the crystal block 2 and block reflected light, preventing excessive reflected light from irradiating the sealing ring 3. This avoids overheating of the sealing ring 3, delays its aging, and reduces the frequency and cost of laser maintenance.
[0037] Specifically, such as Figure 2 , Figure 3 As shown, in this embodiment, the inner wall of the first perforation is provided with at least two elastic portions 42, and an installation space 420 is defined between the abutting ends 422 of all the elastic portions 42. The installation space 420 is used to insert the crystal block 2. The size of the installation space 420 is smaller than the size of the crystal block 2, so that when the crystal block 2 is inserted into the installation space 420, its sides can be abutted and supported by each abutting end 422, and the crystal block 2 can also be fixed by abutting.
[0038] For example, in this embodiment, the crystal block 2 is a cylinder with a circular cross-section and a diameter of 4mm. Multiple elastic portions 42 are evenly arranged circumferentially on the inner wall of the first perforation, forming an installation space 420 with a diameter of 3.9mm. This allows the elastic portions 42 to symmetrically and evenly abut and limit the crystal block 2 on its outer circumferential surface, thus both blocking reflected light and fixing the crystal block 2 to the central axis of the installation space 420, ensuring its positional stability.
[0039] Of course, in some embodiments, such as Figure 4 As shown, crystal block 2 can also be a square prism. In this case, the cross-section of crystal block 2 is oriented in the direction of light, and each of its four sides abuts against an elastic part 42, which can also block reflected light and limit and fix the position.
[0040] Preferably, in order to enhance the blocking effect on reflected light, refer to Figure 4 As shown, the width b of the abutment end 422 (i.e., the dimension along the direction perpendicular to the elastic deformation) is increased in a direction close to the crystal block 2, thereby increasing the cross-sectional size of the abutment end 422 and achieving a better blocking effect.
[0041] Optionally, in some embodiments, the elastic portion 42 and the support portion 41 can cooperate. For example, the inner wall of the first perforation is provided with at least two elastic portions 42, which can abut against the crystal in different directions, thereby pressing the crystal against the inner wall of the first perforation and achieving a limiting and fixing effect. An installation space 420 is defined between the abutting ends 422 of all the elastic portions 42 and the inner wall of the first perforation. The installation space 420 is used to pass through the crystal block 2, and a portion of the support portion 41 can abut against the crystal block 2 to block reflected light, thus protecting the sealing ring 3.
[0042] It should be noted that the cross-sectional shape of the elastic part 42 is at least one of S-shape, Z-shape, arc shape, annular shape, and elliptical annular shape. For example, as shown... Figure 3 As shown, the cross-sectional shape of the elastic part 42 is S-shaped, which can undergo elastic deformation when squeezed by the crystal block 2, thereby generating the elastic force required for contact.
[0043] Of course, in some embodiments, only a portion of the elastic part 42 may be at least one of S-shaped, Z-shaped, arc-shaped, circular, or elliptical. For example, as... Figure 4 As shown, the elastic part 42 includes a deformation segment 423, which is located between the connecting end 421 and the abutting end 422. The width dimension of the abutting end 422 is larger than that of the deformation segment 423, thereby enhancing the effect of blocking reflected light. The cross-sectional shape of the deformation segment 423 is an S-shaped ellipse, which can undergo elastic deformation when squeezed by the crystal block 2, thereby generating the elastic force required for abutment.
[0044] Preferably, in this embodiment, such as Figure 5 As shown, a chamfered structure 4221 is provided between the end face and the side face of the abutment end 422. The crystal block 2 can abut against the chamfered structure 4221 to drive the abutment end 422 to move in a direction close to the connection end 421, thereby facilitating the crystal block 2 to abut against the moving abutment end 422 during installation.
[0045] Optionally, a deformation space 43 is provided and formed between two adjacent elastic parts 42. The deformation space 43 is used to accommodate the compression deformation of the elastic parts 42, so that the two adjacent elastic parts 42 will not interfere with each other when they are compressed and deformed at the same time.
[0046] Preferably, the elastic part 42 and the support part 41 are integrally formed, providing high structural strength. For example, in this embodiment, the elastic part 42 and the deformation space 43 are formed by directly cutting the metal sheet using processes such as wire cutting.
[0047] This utility model also provides a laser, including a housing 1, a crystal block 2, a sealing ring 3, and the aforementioned crystal pressing block 4. The housing 1 has a mounting hole, the crystal block 2 passes through the mounting hole and the end of the crystal block 2 is located outside the mounting hole, the sealing ring 3 and the crystal pressing block 4 are sleeved on the end of the crystal block 2, the crystal pressing block 4 is fixedly connected to the housing 1 and seals the sealing ring 3 against the housing 1, and a space for coolant to flow is formed between the housing 1, the crystal block 2 and the sealing ring 3.
[0048] In this laser, the elastic part 42 can abut against the crystal block 2 and block the reflected light, thus preventing a large amount of reflected light from irradiating the sealing ring 3, thereby preventing the sealing ring 3 from being heated, delaying the aging of the sealing ring 3, and reducing the maintenance frequency and maintenance cost of the laser.

Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model.
