Description

TECHNICAL FIELD

[0001] The utility model relates to an adapter for optical element fixing rod. BACKGROUND

[0002] In optical systems, optical elements often need to be adjusted in position according to different requirements. The optical elements are usually fixed on a fixing rod, and the end of the fixing rod is mounted on an adapter. The adapter is used to extend the fixing rod, or to change the direction of the fixing rod, or to adjust the position of the fixing rod.

[0003] The adapters currently sold on the market are all fixed on the fixing rod by a screw, which results in a small force area of the fixing rod and a loose fixation. The fixing rod or the optical element is easily moved when it is heavy. In addition, in the case of precise positioning, the rotation of the fixing screw will cause the position of the fixing rod to move obviously, resulting in positioning failure. SUMMARY

[0004] The utility model provides an adapter for optical element fixing rod to overcome the defect that the fixing rod for fixing optical elements in the prior art is easily displaced when fixed on the adapter.

[0005] The utility model solves the above technical problems by the following technical scheme:

[0006] The utility model provides an adapter for optical element fixing rod, the fixing rod is used for fixing optical element, the adapter includes main part block and wedge, be equipped with insertion hole and wedge shape hole on the main part block, the insertion hole is used for inserting the fixing rod, the wedge shape hole penetrates the main part block, the periphery of the wedge shape hole and the periphery of the insertion hole form the arc opening that communicates the insertion hole, wedge shape hole with the intersection, the wedge includes the periphery that matches the surface of the wedge shape hole and the abutting surface that protrudes to the insertion hole from the arc opening, the wedge can move to the wedge shape hole and lock tightly, make the abutting surface with the periphery of the fixing rod abut.

[0007] In the technical scheme, after the wedge moves to the wedge shape hole and locks tightly, the abutting surface abuts with the periphery of the fixing rod, and the pressure of the abutting surface of the wedge on the periphery of the fixing rod increases, so that the fixation of the fixing rod and the adapter is more firm. Compared with other fixation methods, the contact area of the abutting surface of the wedge and the fixing rod is larger, and the clamping force is also larger, which is more suitable for heavy load occasions. At the same time, the problem of obvious displacement is also avoided in the process of tightening.

[0008] Preferably, the adapter further comprises a locking member, the wedge is inserted into the wedge-shaped hole from the large end of the wedge-shaped hole, and the locking member is inserted into the wedge-shaped hole from the small end of the wedge-shaped hole; the locking member can be connected with and locked by the inner end surface of the wedge, so that the wedge can move towards the locking member.

[0009] In the technical solution, the locking of the wedge is facilitated by the locking member inserted into the wedge-shaped hole from the small end of the wedge-shaped hole; the pulling force of the locking member on the wedge is consistent with the pressing force of the abutting surface on the fixed rod, so that the clamping force is stable after the fixed rod is locked and is not prone to loosening.

[0010] Preferably, the small end of the wedge-shaped hole forms a first accommodating space for the insertion of the locking member, the large end of the wedge-shaped hole forms a second accommodating space for the insertion of the wedge, a partition plate is formed between the first accommodating space and the second accommodating space, the partition plate is provided with a connecting hole through which the locking member passes, the arc-shaped opening is arranged in the second accommodating space, the inner end surface of the wedge is provided with a locking hole, and the locking member passes through the connecting hole and is inserted into the locking hole after being inserted into the first accommodating space; during the locking process, the locking member can move the wedge towards the locking member.

[0011] In the technical solution, the partition plate limits the movement of the locking member during the locking process, and the wedge can only move towards the locking member under the interaction force of the locking member and the wedge, so that the pressing force of the abutting surface of the wedge on the outer circumferential surface of the fixed rod is increased, and the fixed rod is more firmly fixed to the adapter.

[0012] Preferably, the axis of the locking hole is parallel to the extension direction of the wedge-shaped hole.

[0013] In the technical solution, the axis of the locking hole is parallel to the extension direction of the wedge-shaped hole, so that the acting force of the wedge on the locking member is consistent with the guiding direction of the wedge-shaped hole on the wedge, the wedge can smoothly move in the wedge-shaped hole when the locking member drives the wedge to lock, and the pressing force of the abutting surface of the wedge on the outer circumferential surface of the fixed rod reaches an ideal value.

[0014] Preferably, the insertion hole penetrates through the main body block.

[0015] In the technical solution, the relative position between the main body block and the fixed rod can be adjusted according to the position requirement of the optical element, and the position adjustment space of the fixed rod is large.

[0016] Preferably, the inner circumferential surface of the insertion hole comprises an intermediate section, and the inner circumferential surface of the intermediate section matches the outer circumferential surface of the fixed rod.

[0017] In the technical solution, when the fixing rod is inserted into the insertion hole, the inner circumferential surface of the intermediate section is fitted with the outer circumferential surface of the fixing rod, and the position of the fixing rod is limited.

[0018] Preferably, the inner circumferential surface of the insertion hole further comprises a lead-in section extending from the outer surface of the main block to the connection with the intermediate section, and the diameter of the lead-in section is larger than the diameter of the intermediate section.

[0019] In the technical solution, the lead-in section plays a guiding role in the process of inserting the fixing rod into the insertion hole, and facilitates the insertion of the fixing rod; meanwhile, the space formed between the lead-in section and the outer circumferential surface of the fixing rod facilitates the removal of the fixing rod when it is needed.

[0020] Preferably, the axis of the insertion hole is perpendicular to the axis of the wedge-shaped hole.

[0021] In the technical solution, the pressure of the wedge on the fixing rod is exerted in the transverse direction of the fixing rod, and in combination with the limitation of the insertion hole on the fixing rod, the fixing of the fixing rod is more stable.

[0022] Preferably, the number of the insertion holes is multiple, the number of the wedge-shaped holes is multiple, and the number of the insertion holes and the wedge-shaped holes is the same and one-to-one corresponding.

[0023] In the technical solution, the number and position of the combination of the insertion hole and the wedge-shaped hole can be set according to actual needs, and is not limited to one set.

[0024] Preferably, the main block is composed of at least one cuboid, and the insertion hole is perpendicular to the surface of the main block.

[0025] In the technical solution, the main block is designed as a regular body composed of at least one cuboid, and the insertion hole is perpendicular to the surface of the main block, so that when the main block is placed on a placement surface, the fixing rod is horizontal or vertical to the placement surface, the angle calculation is convenient, and the position adjustment of the fixing rod is facilitated.

[0027] The positive progress effect of the utility model lies in:

[0028] After the wedge moves into the wedge-shaped hole and is locked, the abutting surface abuts against the outer circumferential surface of the fixing rod, the pressure of the abutting surface of the wedge on the outer circumferential surface of the fixing rod is increased, the fixing of the fixing rod and the adapter is more firm, the contact area of the abutting surface of the wedge and the fixing rod is larger, the clamping force is also larger, and it is more suitable for relatively heavy load occasions; meanwhile, the problem of obvious displacement is also avoided in the process of fastening.

[0057] The utility model will be further illustrated below by way of examples, but the utility model is not limited in the scope of the examples.

[0058] Example one

[0059] As Figures 1 to 5 shown, it is example one of the utility model optical element fixed rod adapter.

[0060] The adapter 100 includes a main block 1, wedge 2, the adapter 100 is used to lock the fixed rod 200, and the fixed rod 200 is used to fix the optical element. Wherein, the main block 1 is provided with insertion hole 11 and wedge-shaped hole 12, the insertion hole 11 is used to insert the fixed rod 200, the wedge-shaped hole 12 penetrates the main block 1, and the peripheral surface of the wedge-shaped hole 12 intersects with the peripheral surface of the insertion hole 11 to form the arc-shaped opening 13 that is communicated with the insertion hole 11 and the wedge-shaped hole 12;The wedge 2 includes the outer peripheral surface 21 that is matched with the surface of the wedge-shaped hole 12 and the abutment surface 22 that protrudes from the arc-shaped opening 13 to the insertion hole 11;The wedge 2 can be moved into the wedge-shaped hole 12 and locked, so that the abutment surface 22 is abutted with the outer peripheral surface of the fixed rod 200.

[0061] When the fixed rod 200 needs to be fixed with the adapter 100, the fixed rod 200 is inserted into the insertion hole 11, and the wedge 2 is inserted into the wedge-shaped hole 12. At this time, the abutment surface 22 of the wedge 2 protrudes from the arc-shaped opening 13 to the insertion hole 11. After the wedge 2 is moved into the wedge-shaped hole 12 and locked, the abutment surface 22 is abutted with the outer peripheral surface of the fixed rod 200, and the pressure of the abutment surface 22 of the wedge 2 on the outer peripheral surface of the fixed rod 200 is increased, so that the fixed rod 200 is more firmly fixed with the adapter 100.

[0062] The position of the fixed rod 200 is limited by the insertion hole 11, and the abutment surface 22 of the wedge 2 is also abutted on the outer peripheral surface of the fixed rod 200 to lock the fixed rod 200. Compared with other fixing modes, the contact area of the abutment surface 22 of the wedge 2 with the fixed rod 200 is larger, and the clamping force is also larger, which is more suitable for relatively heavy load occasions. At the same time, the problem of obvious displacement is also avoided in the process of fastening.

[0063] The adapter 100 also includes a locking member 3. The wedge 2 is inserted into the wedge hole 12 through the large port 121, and the locking member 3 is inserted into the wedge hole 12 through the small port 122. The locking member 3 can connect and lock with the inner end face 23 of the wedge 2, allowing the wedge 2 to move in the direction of the locking member 3. During the locking process, the contact surface 22 abuts against the outer peripheral surface of the fixing rod 200, and the pressure gradually increases.

[0064] By setting a locking element 3 that is inserted into the small port 122 of the wedge hole 12, locking the wedge 2 becomes more convenient. The pulling force of the locking element 3 on the wedge 2 and the pressing force of the abutment surface 22 on the fixing rod 200 are in the same direction, so that after the fixing rod 200 is locked, the clamping force is more stable and it is not easy for it to loosen.

[0065] Specifically, such as Figures 1 to 5 As shown, the small port 122 of the wedge-shaped hole 12 forms a first receiving space 123 for inserting the locking member 3, and the large port 121 of the wedge-shaped hole 12 forms a second receiving space 124 for inserting the wedge 2. A partition 125 is formed between the first receiving space 123 and the second receiving space 124. The partition 125 is provided with a connecting hole 126 for the locking member 3 to pass through. An arc-shaped opening 13 is provided in the second receiving space 124. The inner end face 23 of the wedge 2 is provided with a locking hole 24. After the locking member 3 is inserted into the first receiving space 123, it passes through the connecting hole 126 and is inserted into the locking hole 24. During the locking process, the locking member 3 can make the wedge 2 move in the direction of the locking member 3.

[0066] In this embodiment, when it is necessary to fix the fixing rod 200 to the adapter 100, the fixing rod 200 is inserted into the insertion hole 11, and the wedge 2 is inserted into the second receiving space 124. At this time, the abutting surface 22 of the wedge 2 protrudes from the arc-shaped opening 13 into the insertion hole 11 and abuts against the outer peripheral surface of the fixing rod 200. Then, the locking member 3 is inserted into the first receiving space 123, passing through the connecting hole 126 and inserted into the locking hole 24 of the wedge 2. During the locking process, the partition 125 restricts the movement of the locking member 3. Under the interaction force between the locking member 3 and the wedge 2, the wedge 2 can only move in the direction of the locking member 3, thereby increasing the pressure of the abutting surface 22 of the wedge 2 on the outer peripheral surface of the fixing rod 200, making the fixing of the fixing rod 200 and the adapter 100 more secure.

[0067] The axis of the locking hole 24 is parallel to the extension direction of the wedge hole 12, so that the force exerted by the wedge 2 on the locking member 3 is consistent with the guiding direction of the wedge hole 12 on the wedge 2. When the locking member 3 drives the wedge 2 to lock, the wedge 2 can move smoothly in the wedge hole 12, and finally the pressure of the contact surface 22 of the wedge 2 on the outer peripheral surface of the fixing rod 200 reaches the ideal value.

[0068] In the embodiment, the locking member 3 is a locking bolt, and the locking hole 24 is provided with a thread, and the locking member 3 is screwed with the locking hole 24. The head of the locking bolt is located in the first accommodating space 123, and the screw rod of the locking bolt passes through the connecting hole 126 and is inserted into the locking hole 24 of the wedge 2. When the wedge 2 needs to be locked, the wedge 2 can be moved in the wedge-shaped hole 12 to the direction of the locking member 3 by rotating the locking bolt (i.e. the locking member 3), so that the abutting surface 22 of the wedge 2 presses the fixing rod 200.

[0069] In other embodiments, the locking member 3 can also be designed as other locking structures which can lock the wedge 2 and make the abutting surface 22 of the wedge 2 press the fixing rod 200.

[0070] As shown in Figures 1 to 4 the insertion hole 11 passes through the main body block 1, so that the fixing rod 200 can also pass through the main body block 1. The fixing rod 200 can adjust the relative position between the main body block 1 and the fixing rod 200 according to the position requirement of the optical element, and the position adjustment space of the fixing rod is large. In other embodiments, the insertion hole 11 can also be designed not to pass through the main body block 1.

[0071] As shown in Figure 4 the inner periphery of the insertion hole 11 includes an intermediate section 111, and the inner periphery of the intermediate section 111 matches the outer periphery of the fixing rod 200. When the fixing rod 200 is inserted into the insertion hole 11, the inner periphery of the intermediate section 111 matches the outer periphery of the fixing rod 200, so as to limit the position of the fixing rod 200. In addition, the inner periphery of the insertion hole 11 also includes a guide section 112, which extends from the outer surface of the main body block 1 to the intermediate section 111, and the diameter of the guide section 112 is larger than that of the intermediate section 111. The guide section 112 is arranged to guide the insertion of the fixing rod 200 into the insertion hole 11, so as to facilitate the insertion of the fixing rod 200. Meanwhile, when the fixing rod 200 needs to be taken out, the space formed between the guide section 112 and the outer periphery of the fixing rod 200 also facilitates the taking out of the fixing rod 200.

[0072] When the insertion hole 11 is designed to pass through the main body block 1, the guide section 112 can be arranged at both ends of the insertion hole 11, so that the fixing rod 200 can be smoothly inserted or taken out from any one end of the insertion hole 11.

[0073] As shown in Figures 1 to 4 the axis of the insertion hole 11 is perpendicular to the axis of the wedge-shaped hole 12. After the fixing rod 200 is inserted into the insertion hole 11 and the wedge 2 is inserted into the wedge-shaped hole 12, the pressure of the wedge 2 on the fixing rod 200 is applied in the transverse direction of the fixing rod 200, and the insertion hole 11 limits the fixing rod 200, so that the fixing of the fixing rod 200 is more stable.

[0074] Preferably, the extension direction of the abutment surface 22 coincides with the radial plane of the insertion hole 11, so that the pressure of the abutment surface 22 on the fixing rod 200 is completely perpendicular to the fixing rod 200. Combined with the restriction of the fixing rod 200 by the insertion hole 11, the fixing of the fixing rod 200 is more stable.

[0075] In this embodiment, the main body block 1 is a cuboid. There are two insertion holes 11 and two wedge holes 12, which are arranged in two sets in a one-to-one correspondence. The adapter 100 can provide two fixing positions at the same time, and can fix two fixing rods 200 at the same time, or insert the fixing rods 200 into either fixing position.

[0076] The two insertion holes 11 are respectively set on two adjacent surfaces of the main body block 1, and the insertion holes 11 are perpendicular to the surface of the main body block 1. With the above arrangement, when the main body block 1 is placed on the placement surface, the fixing rod 200 is horizontal or vertical to the placement surface, which facilitates angle calculation and position adjustment of the fixing rod 200.

[0077] The two insertion holes 11 are perpendicular to each other, making the two fixed positions of the fixing rod 200 perpendicular to each other, which can be used to fix the two perpendicular fixing rods 200.

[0078] Example 2

[0079] like Figure 6 As shown, the structure of the adapter 100 in this embodiment is basically the same as that in Embodiment 1. The difference is:

[0080] The two insertion holes 11 are parallel to each other, so that the two fixed positions of the fixing rod 200 are parallel to each other, which can be used to fix two parallel fixing rods 200.

[0081] Example 3

[0082] like Figure 7 As shown, the structure of the adapter 100 in this embodiment is basically the same as that in Embodiment 1. The difference is:

[0083] The main body block 1 is composed of two mutually perpendicular cuboids, and two insertion holes 11 are respectively provided on the two cuboids, so that the fixing rod 200 can be inserted into any fixed position.

[0084] In other embodiments, the shape of the main block 1 can also be designed to be other shapes to adapt to different position fixing requirements.

[0085] The utility model is not limited to the above-mentioned embodiment, no matter makes any change in its shape or structure, all falls in the protection scope of the utility model. The protection scope of the utility model is defined by the appended claims, and the skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of the utility model, but these changes and modifications all fall into the protection scope of the utility model.
