Description

Technical Field

[0001] The present invention relates to the technical field of jigs, and in particular to a camera fixing jig. Background Art

[0002] When producing cameras or testing the processing accuracy and performance of cameras, the cameras need to be positioned and fixed to ensure the processing accuracy or the accuracy of the test results. In the existing fixing methods, if a simple cylinder is used for fixing, the problems caused by this are insufficient accuracy or unstable clamping. If a complex fixture is used to position and clamp the camera, for example, bolts and other parts need to be tightened during the installation and disassembly processes, it will not only make the installation and disassembly processes complicated, but also greatly increase the manufacturing cost of the fixture, which does not meet actual needs.

[0003] Therefore, it is of great significance to design a camera fixture with simple structure, easy to clamp the camera and low cost. Summary of the invention

[0004] In order to overcome the deficiencies of the prior art, an object of the present invention is to provide a camera fixing fixture, which has a simple structure, is convenient for clamping a camera, and has a low manufacturing cost.

[0005] The purpose of the present invention is achieved by the following technical solutions:

[0006] A camera fixing fixture, comprising a fixture body, a rotating claw, a torsion spring, a locking rod and a first elastic member;

[0007] The fixture body is provided with a positioning hole for accommodating a camera; the fixture body is also provided with a limiting hole; the rotating claw is pivotally connected to the fixture body, and the two ends of the torsion spring respectively abut against the fixture body and the rotating claw, and the torsion spring is used to drive the rotating claw to limit the camera in the positioning hole;

[0008] The locking rod is movably connected to the rotating claw so that the locking rod can move along the length direction of the locking rod; the two ends of the first elastic member are respectively connected to the fixture body and the rotating claw, and the first elastic member is used to drive the locking rod to insert into the limiting hole.

[0009] Furthermore, the rotating claw is provided with a blind hole, the first elastic member and the locking rod are both located in the blind hole, and two ends of the first elastic member abut against the bottom of the blind hole and the locking rod respectively.

[0010] Furthermore, the rotating claw is further provided with a through hole connected with the blind hole, and the through hole is movably sleeved with a button, and the button is used to squeeze the locking rod so that the locking rod extends out from the limiting hole.

[0011] Furthermore, the button has an extrusion head, which is located at one end of the button close to the blind hole, and the extrusion head is sleeved with a second elastic member, which is used to drive the button away from the locking rod.

[0012] Furthermore, the first elastic member is a telescopic spring, a rubber strip, a rubber column or a rubber band; the second elastic member is a telescopic spring, a rubber strip, a rubber column or a rubber band.

[0013] Furthermore, one of the extrusion head and the locking rod is provided with an inclined surface, and the other is provided with a pressure-bearing portion; the inclined surface is arranged at an acute angle to the axis of the blind hole, and the mutual compression between the pressure-bearing portion and the inclined surface can drive the locking rod to extend out of the limiting hole.

[0014] Furthermore, the camera fixing fixture also includes a rotating shaft, the axis of the rotating shaft is perpendicular to the axis of the positioning hole and is spaced a certain distance apart, the two ends of the rotating shaft are respectively abutted against the rotating claw and the fixture body, and at least one of the rotating claw and the fixture body is pivotally connected to the rotating shaft.

[0015] Furthermore, the torsion spring is sleeved on the rotating shaft.

[0016] Furthermore, the axis of the positioning hole is parallel or perpendicular to the axis of the limiting hole.

[0017] Furthermore, the positioning hole protrudes inwardly along its radial direction to form a positioning step, and the positioning step is used to position the camera.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. This camera fixing fixture positions and limits the camera through the positioning holes, so as to facilitate the rapid positioning and limiting of the camera.

[0020] 2. The torsion spring drives the rotating claw to rotate and press the camera into the positioning hole, thereby restricting the camera into the positioning hole, ensuring the reliability of the camera positioning and fixing.

[0021] 3. The locking rod is movably connected with the rotating claw, and the first elastic member drives the locking rod to move along its own length direction, so that the locking rod can be inserted into the limiting hole of the fixture body, and then the limiting hole limits the rotation of the locking rod, and finally the rotation of the rotating claw is limited when the locking rod cooperates with the limiting hole; to ensure that the camera fixing fixture can firmly position and fix the camera without the action of high-pressure tools such as cylinders and hydraulic cylinders.

[0022] 4. During the unlocking process, as long as the locking rod is disengaged from the limiting hole, the rotating claw can be rotated, so that the camera can be taken out of the positioning hole; that is, the camera can be quickly installed and disassembled, and the operation process is simple and convenient.

[0023] 5. Since the camera fixing fixture has a simple structure and omits a power mechanism, the manufacturing cost is greatly reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be fixedly connected, detachably connected, or integrally connected; it can be mechanically connected or electrically connected; it can be directly connected, or indirectly connected through an intermediate medium, or it can be internally connected between two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] Figure 1-Figure 7 A camera fixing fixture according to a preferred embodiment of the present invention is shown, comprising a fixture body 1 , a rotating claw 2 , a torsion spring 3 , a locking rod 5 and a first elastic member 4 .

[0036] The fixture body 1 is provided with a positioning hole 11 for accommodating the camera 7. The fixture body 1 is also provided with a limiting hole 12 which is spaced a certain distance from the positioning hole 11, and the axis of the positioning hole 11 and the axis of the limiting hole 12 are parallel to each other, perpendicular to each other, or inclined to each other at a certain angle. The rotating claw 2 is pivotally connected to the fixture body 1, and the two ends of the torsion spring 3 respectively abut the fixture body 1 and the rotating claw 2, and the torsion spring 3 is used to drive the rotating claw 2 to limit the camera 7 in the positioning hole 11.

[0037] The locking rod 5 is movably connected with the rotating claw 2 so that the locking rod 5 can move along the length direction of the locking rod 5. The two ends of the first elastic member 4 are respectively connected to the fixture body 1 and the rotating claw 2. The first elastic member 4 is used to drive the locking rod 5 to insert into the limiting hole 12.

[0038] When processing or testing the camera 7, that is, when positioning and fixing the camera 7 by the camera fixing fixture, the camera fixing fixture can be unlocked by manually pulling the locking rod 5. Specifically, after manually pulling the locking rod 5, the locking rod 5 extends out from the limiting hole 12, and the limiting hole 12 is relieved from interfering with the rotation of the rotating claw 2, so that the rotating claw 2 can rotate relative to the fixture body 1. Among them, since the locking rod 5 and the rotating claw 2 are movably connected, the locking rod 5 continues to move relative to the rotating claw 2 so that the locking rod 5 or the first elastic member 4 can apply a squeezing force to the rotating claw 2, so that the rotating claw 2 overcomes the elastic force of the torsion spring 3 and rotates, that is, the camera fixing fixture is unlocked. After unlocking, since the rotating claw 2 rotates, the rotating claw 2 will not interfere with the camera 7 being installed in the positioning hole 11. After positioning the camera 7 through the positioning hole 11; loosen the locking rod 5, under the action of the torsion spring 3, the rotating claw 2 rotates relative to the fixture body and resets, and squeezes the camera 7 into the positioning hole 11. At the same time, under the action of the first elastic member 4, the locking rod 5 moves along the position close to the limiting hole 12, and when the rotating claw 2 is reset, the locking rod 5 is also inserted into the limiting hole 12; at this time, since the locking rod 5 and the rotating claw 2 are in a movable sleeve relationship, the rotating claw 2 cannot rotate relative to the fixture body under the interference of the limiting hole 12 on the rotation of the locking rod 5. In short, after the locking of the camera fixing fixture is achieved, as long as the locking rod 5 and the limiting block are in a matching state, the rotating claw 2 cannot rotate, thereby firmly limiting the camera 7 in the positioning hole 11.

[0039] Obviously, the camera fixing fixture of the present invention positions and limits the camera 7 through the positioning hole 11, thereby facilitating the rapid positioning and limiting of the camera 7. The rotating claw 2 is driven to rotate by the torsion spring 3 to press the camera 7 into the positioning hole 11, thereby limiting the camera 7 into the positioning hole 11, and ensuring the reliability of the positioning and fixing of the camera 7. The locking rod 5 is movably connected with the rotating claw 2, and the locking rod 5 is driven by the first elastic member 4 to move along its own length direction, so that the locking rod 5 can be inserted into the limiting hole 12 of the fixture body 1, and then the limiting hole 12 limits the rotation of the locking rod 5, and finally the rotation of the rotating claw 2 is limited when the locking rod 5 cooperates with the limiting hole 12; so as to ensure that the camera 7 fixing fixture of the present invention can firmly position and fix the camera 7 without the action of high-pressure tools such as cylinders and hydraulic cylinders. Moreover, during the unlocking process, as long as the locking rod 5 is disengaged from the limiting hole 12, the rotating claw 2 can be rotated, so that the camera 7 can be taken out from the positioning hole 11; that is, the camera 7 can be quickly installed and removed, and the operation process is simple and convenient. Furthermore, since the camera fixing fixture has a simple structure and omits a power mechanism, the manufacturing cost is greatly reduced.

[0040] Preferably, the rotating claw 2 is provided with a blind hole 21, the first elastic member 4 and the locking rod 5 are both located in the blind hole 21, and the two ends of the first elastic member 4 abut the bottom of the blind hole 21 and the locking rod 5, respectively. In this way, the locking rod 5 can be placed in a hidden space protected by the blind hole 21, and the first elastic member 4 is also placed in a hidden space, thereby greatly reducing the probability of failure, damage and other problems of the first elastic member 4 and the locking rod 5. Moreover, the blind hole 21 can reliably guide and limit the first elastic member 4, thereby further ensuring the normal reset of the locking rod 5. Among them, the connection relationship between the first elastic member 4 and the bottom of the blind hole 21 can be a fixed connection or a detachable abutment; the connection relationship between the first elastic member 4 and the locking rod 5 can also be a fixed connection or a detachable abutment. Obviously, in this embodiment, as a preferred implementation, the blind hole 21 movably sleeves the locking rod 5 (that is, the rotating claw 2 movably sleeves the locking rod 5). In addition to this arrangement, the blind hole 21 can also be arranged on the locking rod 5, and a guide column (cylindrical column, square column or irregular column) adapted to the blind hole 21 of the locking rod 5 can be arranged on the rotating claw 2. It should be further explained here that the first elastic member 4 can be fixed to the limiting hole 12, and the other end of the first elastic member 4 is fixedly connected to the locking rod 5 to drive the locking rod 5 to be inserted into the limiting hole 12.

[0041] Furthermore, the rotating claw 2 is also provided with a through hole 22 connected to the blind hole 21, and a button 23 is movably sleeved in the through hole 22, and the button 23 is used to squeeze the locking rod 5 so that the locking rod 5 extends out from the limiting hole 12. That is, the button 23 can move along the axial direction of the through hole 22, thereby squeezing the locking rod 5 and moving the locking rod 5, thereby realizing the separation of the locking rod 5 from the limiting block, and further, when the button 23 further squeezes the locking rod 5, the locking rod 5 can also be pressed continuously, so that the locking rod 5 or the first elastic member 4 squeezes the rotating claw 2, and the rotating claw 2 rotates relative to the fixture body 1, thereby realizing the rapid installation and removal of the camera 7. Among them, in addition to the translational squeezing of the locking rod 5 by the button 23, a knob can also be set in the through hole 22, and the knob can be set as a cam structure to drive the locking rod 5 to compress the first elastic member 4, so that the rotating claw 2 rotates relative to the fixture body. Moreover, according to the positional relationship between the axis of the through hole 22 and the axis of the blind hole 21, the button 23 can be flexibly arranged, so that the button 23 can easily drive the locking rod 5 to squeeze the first elastic member 4 and disengage from the limiting hole 12; for example, the axis of the through hole 22 and the axis of the blind hole 21 are not perpendicular but inclined at a certain angle, and at this time, if the button 23 squeezes the locking rod 5 along the axial direction of the through hole 22, the locking rod 5 can squeeze the first elastic member 4. However, this arrangement is difficult to process, and from the perspective of the ease of manufacturing of the camera fixing fixture, as a preferred embodiment: the axis of the through hole 22 and the axis of the blind hole 21 are perpendicular to each other.

[0042] Furthermore, in order to facilitate the automatic resetting of the button 23 and to facilitate repeated pressing of the button 23, the button 23 has an extrusion head 231, which is located at one end of the button 23 close to the blind hole 21, and the extrusion head 231 is sleeved with a second elastic member 24, which is used to drive the button 23 away from the locking rod 5.

[0043] In this embodiment, the first elastic member 4 is a telescopic spring (compression spring or tension spring), a rubber strip, a rubber column or a rubber band; the second elastic member 24 is a telescopic spring, a rubber strip, a rubber column or a rubber band.

[0044] According to the preferred embodiment described above, the axis of the through hole 22 is perpendicular to the axis of the blind hole 21. As a further preferred embodiment, one of the extrusion head 231 and the locking rod 5 is provided with an inclined surface 232, and the other is provided with a pressure-bearing portion 51; the inclined surface 232 is arranged at an acute angle to the axis of the blind hole 21, and the pressure-bearing portion 51 and the inclined surface 232 are pressed against each other to drive the locking rod 5 to extend from the limiting hole 12. Obviously, such a setting is more convenient for a person to press the button 23. The inclined surface 232 can be a plane or a curved surface. In this embodiment, the inclined surface 232 is a conical surface.

[0045] Preferably, the camera fixing jig further comprises a rotating shaft 6, the axis of the rotating shaft 6 is perpendicular to the axis of the positioning hole 11 and is spaced a certain distance apart, the two ends of the rotating shaft 6 are respectively abutted against the rotating claw 2 and the jig body 1, and at least one of the rotating claw 2 and the jig body 1 is pivotally connected to the rotating shaft 6. It can be understood that the rotating shaft 6 may be a part of the rotating claw 2 itself or the jig body 1 itself, or the rotating shaft 6 may also be a separate part; as long as it is ensured that the rotating claw 2 can rotate relative to the jig body 1 on the basis of the rotating shaft 6 as an intermediate connecting carrier. As an alternative, the rotating shaft 6 may also be replaced by a spherical concave surface and a spherical protrusion, that is, one of the rotating claw 2 and the jig body 1 is provided with a spherical concave surface, and the other is provided with a spherical protrusion, so as to achieve a rotational connection relationship between the two.

[0046] Obviously, on the basis of setting the rotating shaft 6, in order to make the torsion spring 3 connected reliably, in addition to fixing the two ends of the torsion spring 3 on the rotating claw 2 and the fixture body 1 respectively (such as welding, bonding, bundling, jack fixing and other connection methods). As a more preferred embodiment, the torsion spring 3 is sleeved on the rotating shaft 6; such a setting is not only convenient for quickly completing the fixation and installation of the torsion spring 3, but also the torsion spring 3 cannot escape the limit of the rotating shaft 6 even if it fails, and the limit method is more reliable. Moreover, since the sleeve relationship is relatively reliable, the two ends of the torsion spring 3 can respectively abut the rotating claw 2 and the fixture body 1, and there is no need to further complete the process of fixing the two ends of the torsion spring 3, thereby reducing the production difficulty of the camera fixing fixture.

[0047] Preferably, the rotating claw 2 has an extrusion surface 25. When the rotating claw 2 limits the camera 7 in the positioning hole 11, the extrusion surface 25 is located within the range of the positioning hole 11 along its axial extension; that is, at this time, the extrusion surface 25 is located directly above or directly in front of the positioning hole 11. The extrusion surface 25 limits the position of the camera 7, so that the camera 7 can be firmly fixed in the positioning hole 11. The extrusion surface 25 can be finely processed, so that the camera 7 can be finely positioned twice by the extrusion surface 25, thereby further improving the positioning accuracy of the camera fixing fixture.

[0048] Obviously, in this embodiment, two rotating claws 2 are provided, and the two rotating claws 2 are symmetrically arranged on two opposite sides of the positioning hole 11. Of course, this embodiment does not absolutely limit the specific number of rotating claws 2, but should allow any number of rotating claws 2.

[0049] In addition, the positioning hole 11 can be a rectangular structure, a polygonal structure, or a circular structure. Obviously, the shape of the positioning hole 11 mainly depends on the outer contour of the camera 7, and a complete match is the best, but it is also limited to a complete match; thus, the positioning hole 11 is allowed to be an irregular shape.

[0050] In order to facilitate the positioning and limiting of the camera 7 by the positioning hole 11. Preferably, the positioning hole 11 protrudes inward along its radial direction to form a positioning step 13, and the positioning step 13 is used to position the camera. That is, by clamping the camera 7 with the positioning step 13 and the rotating claw 2, the camera 7 can be securely positioned and fixed. Among them, the positioning step 13 surrounds the circumference of the positioning hole 11 to form a closed-loop structure. However, it should be explained here that in addition to positioning and limiting the camera 7 by the positioning step 13, the positioning hole 11 can also be blocked by providing a limiting boss outside the positioning hole 11. Alternatively, a plurality of positioning columns can be raised in the positioning hole 11 to position the camera 7. Alternatively, the positioning block can also be set to a gradient aperture shape to achieve the positioning of the camera 7.

[0051] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
