Description

Technical Field

[0001] The utility model relates to the field of mechanical testing, in particular to a rotation limiting self-locking device for lock-type test pieces and a detection mechanism thereof. Background Art

[0002] In the field of mechanical testing, such as the testing of locks, it is necessary to rotate one or more locks at a certain angle to measure the performance parameters and stability of the locks. The current self-locking rotating structure is large in size, and in the process of self-locking and unlocking, it is necessary to apply additional force or torque in addition to the rotation direction, which is inefficient and complex in structure.

[0003] Therefore, how to simplify its mechanical structure and facilitate its use is a technical problem that needs to be solved urgently in this field. Utility Model Content

[0004] In order to solve at least one of the above technical problems, the utility model provides a rotation limit self-locking device, comprising:

[0005] Mounting seat;

[0006] The limiting seat is arranged on the mounting seat, and comprises a first hole, a second hole, a first limiting portion and a second limiting portion;

[0007] The hinge comprises an upper rotating part and a lower rotating part; the upper rotating part is connected to the test bench; the lower rotating part is connected to the limit seat;

[0008] The test bench has a spring plunger corresponding to the first hole and the second hole arranged on the side thereof; a receiving cavity for receiving the test piece arranged on the front thereof; and the test bench rotates around a hinge.

[0009] In this embodiment, a rotation limit self-locking device of the utility model is provided, wherein the mounting seat, the limit seat, the hinge, and the test bench cooperate so that the test bench can rotate up and down with the hinge and be limited in the limit seat. The test bench rotates around the hinge in a first direction, such as clockwise, so that the ball of the spring plunger is inserted into the first hole corresponding thereto, and the test bench is limited to the first limit portion; on the contrary, the test bench rotates around the hinge in a second direction, such as counterclockwise, so that the ball of the spring plunger is inserted into the second hole corresponding thereto, and the test bench is limited to the second limit portion. Then, at the same time, the test piece contained in the test bench can rotate up and down flexibly and be limited to the first limit portion and the second limit portion. The test piece is a lock as an adaptability example, but the application scope of the utility model is not arbitrarily limited. Its quality performance needs to be tested before production, such as service life, number of repeated opening and closing times, switch elasticity, switch recovery time, etc. If the conventional method is used manually, it is necessary to press continuously, which is not only labor-intensive and inefficient, but also can only be tested individually, which is time-consuming and labor-intensive. The rotary limit self-locking device of the utility model is adopted, and the lock row is placed in the accommodating cavity of the test bench, so that the test bench is repeatedly rotated around the hinge 3, so that its spring plunger falls into the first hole or the second hole, and is limited to the first limit part and the second limit part, so as to achieve the detection purpose by repeatedly opening and closing the lock core, thereby greatly improving the detection efficiency and consistency of the detection results. Moreover, the structure of the device is simple.

[0010] Furthermore, the first hole is arranged on the lower side of the limit seat, and the first limit portion extends forward; the second hole is arranged on the upper side of the limit seat, and the second limit portion extends downward; the first limit portion and the second limit portion are arranged to form an angle of a certain angle.

[0011] Furthermore, the left middle portion of the limiting seat also includes a fan-shaped recess with a certain angle, and the radius of the fan-shaped recess is greater than the maximum length of the upper rotating part of the hinge.

[0012] Furthermore, the limit seats are arranged on both sides of the mounting seat, the test bench is arranged between the two limit seats, and the two limit seats are fixedly connected by a connecting rod.

[0013] Furthermore, a plurality of buffer pads are arranged on the first limiting portion and the second limiting portion of the limiting seat.

[0014] Furthermore, the thickness of the first limiting portion of the limiting seat relative to the upper surface of the mounting seat is greater than 3 centimeters.

[0015] Furthermore, the hinge is a damping hinge.

[0016] Furthermore, the test bench rotates about the hinge in a first direction, so that the ball of the spring plunger is inserted into the corresponding first hole, and the test bench is limited to the first limit portion; conversely, the test bench rotates about the hinge in a second direction, so that the ball of the spring plunger is inserted into the corresponding second hole, and the test bench is limited to the second limit portion.

[0017] According to another aspect of the utility model, a detection mechanism is also provided, including a rotation limit self-locking device and a baffle;

[0018] The rotation limit self-locking device is any of the above-mentioned rotation limit self-locking devices;

[0030] The utility model provides a rotation limit self-locking device, referring to Figure 1 , Figure 2 , Figure 4 and Figure 5 , including: a mounting seat 1, a limiting seat 2, a hinge 3, and a test bench 4;

[0031] Mounting base 1; optional mounting base plate;

[0032] The limiting seat 2 is arranged on the mounting seat 1, and includes a first hole 21, a second hole 22, a first limiting portion 23 and a second limiting portion 24; preferably, the first hole 21 is arranged on the lower side of the limiting seat 2, and the first limiting portion 23 extends forward; the second hole 22 is arranged on the upper side of the limiting seat 2, and the second limiting portion 24 extends downward; more preferably, as Figure 2 As shown, the first hole 21 is set at the lower right of the limit seat 2; the second hole 22 is set at the upper left of the limit seat 2. Specifically, the number, size, position of the first hole and the second hole, the spacing distance between the holes, and the length, angle, position, etc. of the first limit part and the second limit part can be arbitrarily set by those skilled in the art according to the test bench required to be carried later. Preferably, the first limit part and the second limit part are set to form an angle of a certain angle, preferably according to the required rotation angle;

[0033] The hinge 3 includes an upper rotating member 31 and a lower rotating member 32; the upper rotating member 31 is connected to the test bench 4; the lower rotating member 32 is connected to the limit seat 2; the test bench 4 is provided with a spring plunger 41 corresponding to the first hole 21 and the second hole 22 on the side; and a receiving cavity 43 for receiving the test piece is provided on the front; the test bench 4 rotates up and down with the hinge 3. Specifically, the position, size and number of the spring plunger 41 correspond to the first hole 21 and the second hole 22. For example, Figure 2 and Figure 5 As shown, the number of the first hole 21 , the second hole 22 and the spring plunger 41 are all two, and the spacing distances are equal, so that when the test bench 4 rotates up and down, the spring plunger 41 can be accurately inserted into the first hole 21 or the second hole 22 .

[0034] In this embodiment, a rotation limit self-locking device of the utility model is provided. The mounting seat 1, the limit seat 2, the hinge 3, and the test bench 4 cooperate so that the test bench 4 can rotate up and down with the hinge 3 and be limited in the limit seat 2. Figure 1 It can be seen that the test bench 4 rotates around the hinge 3 in a first direction, such as clockwise, so that the ball of the spring plunger 41 is inserted into the corresponding first hole 21, and the test bench 4 is limited to the first limit portion 23; on the contrary, the test bench 4 rotates around the hinge 3 in a second direction, such as counterclockwise, so that the ball of the spring plunger 41 is inserted into the corresponding second hole 22, and the test bench 4 is limited to the second limit portion 24. Then, at the same time, the test piece contained in the test bench 4 can be flexibly rotated up and down, and limited to the first limit portion and the second limit portion. The test piece is a lock as an adaptability example, but the scope of application of the utility model is not arbitrarily limited. Before production, its quality performance needs to be tested, such as service life, repeated opening and closing times, switch elasticity, switch recovery time, etc. If it is manually done in a conventional way, it needs to be pressed continuously, which is not only labor-intensive and inefficient, but also can only be tested individually, which is time-consuming and labor-intensive. The rotary limit self-locking device of the utility model is adopted to place the lock row into the accommodating cavity 43 of the test bench 4, so that the test bench 4 repeatedly rotates around the hinge 3, so that its spring plunger 41 falls into the first hole or the second hole, and is limited to the first limit part and the second limit part, so as to repeatedly open and close the lock core to achieve the purpose of detection, which greatly improves the detection efficiency and consistency of the detection results. Moreover, the structure of the device is simple. Preferably, the specific angle of the rotation can be arbitrarily set according to the actual needs of the test piece, preferably 90 degrees; the power of the rotation can be manual, or driven by a driving member such as a motor.

[0035] Preferably, reference Figure 1 A groove is provided in the middle of the second limiting portion 24 , and the width of the groove is greater than the rotation axis of the hinge 3 .

[0036] In this embodiment, a groove is provided in the middle section of the second limiting portion to avoid the rotating axis of the hinge, reduce friction and collision, and improve the service life and stability of the device.

[0037] Preferably, reference Figure 1 and Figure 2 There are several threaded holes on the mounting seat 1, and there are slots corresponding to the screw holes under the limit seat 2. The width of the slot in the left and right directions is greater than the major diameter of the screw holes on the mounting seat. The bolts pass through the slots and threaded holes, and the limit seat 2 is fastened to the mounting seat 1 with nuts.

[0038] In this embodiment, by loosening the bolts and moving the limit seat within the slotted hole, the limit seat can move left and right on the mounting seat, thereby expanding the adjustable range of the limit seat and improving the application range of the entire device.

[0039] Preferably, reference Figure 2 and Figure 4 The left middle part of the limit seat 2 also includes a fan-shaped recess 25 with a certain angle, and the radius of the fan-shaped recess is greater than the maximum length of the upper rotating member 31 of the hinge 3 to avoid the friction between the upper rotating member 31 and the limit seat 2 during the rotation process, thereby reducing the friction resistance during the rotation process.

[0040] Preferably, reference Figure 1 , Figure 2 and Figure 3 The limit seats 2 can be arranged on both sides of the mounting seat 1, and the test bench 4 is arranged between the two limit seats. More preferably, the two limit seats can be directly connected by a connecting rod 25. For example, refer to Figure 1 The two ends of the connecting rod 26 are fixedly connected with the two limit seats by bolts.

[0041] In this embodiment, the limit seats are arranged at both ends of the mounting seat, which can prevent one end of the test bench from being suspended in the air, causing deformation of the rotating part and the limit seat on the hinge; a connecting rod is arranged between the two limit seats, so that the distance between the two limit seats does not change due to deformation, thereby avoiding friction between the test bench and the limit seat, generating friction resistance and unnecessary wear.

[0042] Preferably, reference Figure 1 and Figure 2 A plurality of buffer pads are arranged on the first limiting portion 23 and the second limiting portion 24 of the limiting seat.

[0043] In this embodiment, buffer pads are provided on the first limiting portion and the second limiting portion of the limiting seat, which can reduce the rigid impact of the test bench on the limiting seat and increase the service life of the device.

[0044] Preferably, the thickness of the first limiting portion 23 on the limiting seat 2 relative to the upper surface of the mounting seat 1 is greater than 3 cm;

[0045] In this embodiment, the second limiting portion of the limiting seat is provided with a certain thickness relative to the upper surface of the mounting seat, so as to avoid the test bench pressing the hand during manual rotation and improve the safety of the entire device.

[0046] Preferably, the hinge 3 is a damping hinge.

[0047] In this embodiment, the hinge 3 is a damping hinge, which can play a certain buffering role during the rotation of the test bench, prevent the test bench from generating a rigid impact on the limit seat, and improve the service life of the device.

[0048] Preferably, reference Figure 5 , a plurality of through holes 42 are provided on both sides of the left and right sides of the test bench 4 for the cable outlet of the measuring lock-like device; more preferably, the edge of the through hole 42 is provided with a chamfer or a rounded corner; more preferably, an anti-friction protection pad with a corresponding configuration can be provided in the through hole 42 to protect the cable of the measuring lock-like device; preferably, the top of the test bench 4 also includes a rounded rectangular groove 44 provided on the top to facilitate the grasping of the test bench 4 when manually rotating. It can be understood that the rounded rectangular groove 44 can also be a handle-like protrusion, which is not limited to the drawings.

[0049] A detection mechanism comprises any one of the above-mentioned rotation limit self-locking devices and a baffle 5, wherein the baffle 5 is arranged at the front end of the rotation limit self-locking device. Figure 6 As shown, the baffle 5 is installed in the mounting hole on the mounting seat 1.

[0050] In this embodiment, a baffle is provided in front of the rotation limit self-locking device, and the lock to be tested is used as an adaptability example, but it does not limit the application scope of the utility model in any way; during the detection process, the lock to be tested is placed in the accommodating cavity of the test bench, and rotates up and down with the test bench. The lock core repeatedly presses against the baffle to detect the quality performance of the lock to be tested, such as service life, number of repeated opening and closing times, switch elasticity, switch recovery time, etc.

[0051] Compared with manual inspection methods, the ability to measure multiple test pieces at a time can greatly improve the efficiency of inspection and the consistency of inspection results.

[0052] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
