Description

Technical Field

[0001] This utility model relates to the field of optical instrument manufacturing technology, specifically to a splicable prism support assembly. Background Technology

[0002] In the field of optics, prisms are widely used in various optical instruments and equipment, such as telescopes, microscopes, spectrometers, and laser processing systems. Their functions encompass key optical operations such as changing the direction of light paths, splitting beams, combining beams, and converting polarization, playing a decisive role in the performance and imaging quality of optical systems. The prism support assembly, as a crucial component for fixing and supporting the prism, is so well-designed that its precise positioning and stable operation directly affect the prism's stability.

[0003] Existing modular prism holder assemblies mainly consist of two clamping plates with specific shaped grooves. These plates are typically made of metal, such as aluminum alloy or stainless steel, to ensure sufficient strength and stability. The shape of the grooves matches the side profile of the prism. However, a significant drawback is that they can only hold prisms of a fixed size, and the prism dimensions used are extremely diverse. When faced with the need for prisms of different sizes, existing modular prism holder assemblies fall short. If a prism exceeding its clamping range is required, it either cannot be installed or requires significant time and cost to redesign and manufacture a suitable holder assembly. Each prism replacement may necessitate replacing the entire holder, which not only consumes considerable time and effort but may also affect the stability of the optical system due to frequent holder replacements, thus impacting the accuracy and reliability of experimental results. Utility Model Content

[0004] The purpose of this invention is to provide a modular prism support assembly to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides a splicable prism support assembly, including an arc-shaped frame and a prism, a mounting plate fixedly installed at both ends of the arc-shaped frame; a first elastic member, one end of which is fixedly installed on the mounting plate, and the other end of the first elastic member is spaced apart from the mounting plate, the first elastic member is C-shaped and has an arc-shaped groove; a second elastic member, both ends of which are fixedly installed on the two ends of the first elastic member, the bend of the second elastic member passing through the arc-shaped groove, and the bend of the second elastic member is set as an acute angle; a clamping block, fixedly installed on the other end of the first elastic member, the clamping block has a groove, and the edge of the prism abuts against the groove.

[0006] Furthermore, a damper and a spring are fixedly installed between the two ends of the first elastic element, and the spring is sleeved on the outer wall of the damper.

[0007] Furthermore, the cross-section of the clamping block is set to a trapezoidal shape, and the inclined surface of the clamping block corresponds to the edge of the prism.

[0008] Furthermore, the mounting plate, the arc-shaped groove, and the second elastic element are made of spring steel.

[0009] Furthermore, a slider is fixedly installed on the clamping block, the slider is T-shaped, and a T-shaped groove adapted to the slider is provided on the mounting plate.

[0010] Furthermore, the slider is provided with a mounting groove, and multiple balls are provided in the mounting groove.

[0011] Furthermore, a protective layer is integrally formed on the groove.

[0012] Furthermore, a mounting block is fixedly installed at the bottom of the arc-shaped frame, a support rod is threadedly connected to the mounting block, and a base is threadedly connected to the bottom end of the support rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this invention, when fixing the prism, it is placed in the clamping area and initially positioned using the fitting groove. Pressure applied by the prism causes the clamping block mounted on the first elastic element to bear force. One end of the C-shaped first elastic element is fixed to the mounting plate, while the other end is spaced apart, thus generating elastic deformation. This causes the connected second elastic element, with its angled end passing through the arc-shaped groove, to deform, enhancing the restoring force to tightly clamp the prism. When removing the prism, a reverse force is applied to overcome the elastic force and loosen the clamping block. The first and second elastic elements, through elastic deformation, can accommodate prisms of different sizes, eliminating the need to reconstruct supports for different sizes, saving time and cost.

[0015] 2. In this invention, various vibrations may occur in the external environment, such as vibrations generated by the operation of equipment or personnel movement in the laboratory, which may be transmitted to the prism support assembly. The spring, being elastic, can absorb and buffer these vibration energies to a certain extent, while the damper can further suppress the back-and-forth vibration of the spring, enabling the entire support assembly to recover to a stable state more quickly when subjected to vibration disturbances, ensuring that the prism always remains in a precise position, thereby guaranteeing the stability of the optical system and the imaging quality.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 This utility model provides a technical solution:

[0023] See Figures 1-4 As shown, a splicable prism support assembly includes an arc-shaped frame 4 and a prism 15, a mounting plate 5 fixedly installed at both ends of the arc-shaped frame 4; a first elastic member 6, one end of which is fixedly installed on the mounting plate 5, and the other end of the first elastic member 6 is spaced apart from the mounting plate 5, the first elastic member 6 is C-shaped, and an arc-shaped groove 7 is provided on the first elastic member 6; a second elastic member 8, both ends of which are fixedly installed on the two ends of the first elastic member 6, the bend of the second elastic member 8 passing through the arc-shaped groove 7, and the bend of the second elastic member 8 is set as an acute angle; a clamping block 11, fixedly installed at the other end of the first elastic member 6, the clamping block 11 is provided with a groove, and the edge of the prism 15 abuts against the groove.

[0024] When it is necessary to fix the prism 15, first place the prism 15 in the fixing area formed by the clamping block 11. Since the clamping block 11 has a groove that matches the edge of the prism 15, the edge of the prism 15 can abut against the groove to achieve initial positioning.

[0025] During the placement of the prism 15, the prism 15 exerts a certain pressure on the clamping block 11. The clamping block 11 is fixedly installed at the other end of the first elastic member 6, which is C-shaped, with one end fixedly installed on the mounting plate 5 and the other end having a certain distance from the mounting plate 5. Therefore, the first elastic member 6 will undergo elastic deformation under the pressure of the prism 15.

[0026] Meanwhile, the second elastic element 8 is fixedly installed at both ends of the first elastic element 6, and its bends penetrate the arc-shaped groove 7 and are set as acute angles. When the first elastic element 6 deforms, it will cause the second elastic element 8 to deform together. This deformation of the second elastic element 8 will further enhance the elastic restoring force of the first elastic element 6, so that the clamping block 11 can tightly clamp the prism 15.

[0027] When it is necessary to remove the prism 15, apply a force opposite to that used when it is fixed to overcome the elastic forces of the first elastic element 6 and the second elastic element 8, so that the clamping block 11 releases the prism 15 and the prism 15 can be removed.

[0028] By utilizing the elastic deformation characteristics of the first elastic element 6 and the second elastic element 8, it is possible to adapt to prisms 15 of different sizes. When the size of the prism 15 is large, the first elastic element 6 and the second elastic element 8 will deform to a greater extent to provide sufficient clamping force; when the size of the prism 15 is small, they can also achieve stable clamping through smaller deformation, eliminating the need to redesign and manufacture suitable bracket assemblies for prisms 15 of different sizes, thus greatly saving time and cost.

[0029] See Figure 3-4 A damper 9 and a spring 10 are fixedly installed between the two ends of the first elastic element 6, and the spring 10 is sleeved on the outer wall of the damper 9.

[0030] Various vibrations may occur in the external environment, such as vibrations generated by the operation of equipment or personnel movement in the laboratory, which may be transmitted to the prism 15 support assembly. The spring 10 is elastic and can absorb and buffer this vibration energy to a certain extent. The damper 9 can further suppress the back-and-forth vibration of the spring 10, allowing the entire support assembly to recover to a stable state more quickly when subjected to vibration disturbances, ensuring that the prism 15 always remains in a precise position, thereby guaranteeing the stability of the optical system and the imaging quality.

[0031] During long-term use, the elasticity of the first elastic element 6 may change due to factors such as material fatigue. The combination of spring 10 and damper 9 can compensate for the effects of this change, keeping the clamping force of clamp 11 on prism 15 relatively stable. Even after long-term use, the fixing effect of prism 15 can still be guaranteed, extending the service life of the bracket assembly.

[0032] See Figure 4 The cross-section of the clamping block 11 is set to a trapezoidal shape, and the inclined surface of the clamping block 11 corresponds to the edge of the prism 15.

[0033] The inclined surface of the trapezoidal clamp 11 matches the edges of the prism 15, enabling precise positioning. When the prism 15 is placed on the clamp 11, its edges fit tightly against the inclined surface of the clamp 11, allowing the prism 15 to be precisely fixed on the support assembly, reducing errors during installation and improving the accuracy and stability of the optical system.

[0034] See Figure 1-4 The mounting plate 5, the arc groove 7, and the second elastic element 8 are made of spring steel.

[0035] Spring steel possesses excellent elasticity, capable of elastic deformation under stress and returning to its original shape after the force is removed. This characteristic allows the mounting plate 5, the arc-shaped groove 7, and the second elastic element 8 to adapt to the installation requirements of prisms 15 of different sizes. For example, the second elastic element 8 can be elastically adjusted according to the size and shape of the prism 15, providing suitable clamping force, while remaining flexible and resistant to loss of elasticity due to repeated deformation during long-term use. The mounting plate 5 and the arc-shaped groove 7 can also utilize the elasticity of spring steel to better cooperate with other components, ensuring the stability and reliability of the entire support assembly. Furthermore, the toughness of spring steel allows it to withstand a certain degree of impact and vibration, making it less prone to breakage and improving the durability of the support assembly in practical use.

[0036] See Figure 3-4 A slider 12 is fixedly installed on the clamping block 11. The slider 12 is T-shaped, and a T-shaped groove 14 adapted to the slider 12 is provided on the mounting plate 5.

[0037] The T-shaped structure provides excellent limiting functionality. The T-shaped slider 12 is secured within the T-shaped groove 14, effectively restraining the block in both the horizontal and vertical directions, thus ensuring a more stable connection between the clamping block 11 and the mounting plate 5. During the use of the bracket assembly, even under certain external impacts or vibrations, the T-shaped slider 12 will not easily dislodge from the T-shaped groove 14, thereby guaranteeing that the clamping block 11 can continuously and stably fix the prism 15, improving the reliability of the entire bracket assembly.

[0038] See Figure 3 The slider 12 has an installation groove, and multiple balls 13 are installed in the installation groove.

[0039] The presence of the ball bearing 13 transforms the sliding friction between the slider 12 and the T-slot 14 on the mounting plate 5 into rolling friction. The coefficient of rolling friction is much smaller than the coefficient of sliding friction, which makes the clamping block 11 move more smoothly and easily within the T-slot 14 via the slider 12. It also reduces wear caused by friction and extends the service life of the slider 12 and the T-slot 14.

[0040] See Figure 1-4 The groove has an integrally formed protective layer.

[0041] The protective layer can prevent the prism 15 from directly contacting the groove, and prevent the prism 15 from being scratched or bumped by the edge or surface of the groove during installation, disassembly or use, thereby protecting the optical surface and accuracy of the prism 15 and ensuring that the performance of the prism 15 is not affected.

[0042] The protective layer generally has a certain degree of roughness or elasticity, which can increase the friction between it and the prism 15, making the prism 15 more securely fixed in the groove, reducing the possibility of the prism 15 shifting due to vibration or external force, and improving the clamping stability of the entire support assembly for the prism 15.

[0043] See Figure 1-2 An installation block 3 is fixedly installed at the bottom of the arc-shaped frame 4. The installation block 3 is threadedly connected to a support rod 2, and the bottom end of the support rod 2 is threadedly connected to a base 1.

[0044] Threaded connections are a common and convenient method of connection. During assembly, simply tighten the mounting block 3 to the support rod 2, and the support rod 2 to the base 1 by rotating them; no complex tools or special processing are required. For disassembly, simply rotate in the opposite direction to easily separate the components, facilitating transportation, storage, and replacement or repair of individual parts.

[0045] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
