Description

Technical Field

[0001] This utility model belongs to the field of pressure sensor technology, specifically a quick-installation pressure sensor clamp structure. Background Technology

[0002] A pressure sensor is a sensor that senses pressure and converts the pressure signal into an electrical signal output according to a certain rule. Pressure sensors are usually composed of a pressure-sensitive element and a signal processing unit, and can be used to monitor and test various devices. Pressure sensors have a wide range of applications, such as medical devices, environmental monitoring, aerospace, industrial automation, consumer electronics, and the automotive industry.

[0003] Existing clamps are composed of two semicircular rings, with one end of the two semicircular rings hinged together and the other end tightened by a screw or other structure. In other words, the applicable diameter range of a clamp is related to its own length and the length of the screw, and tightening depends on the screw. If the screw is too long, tightening will be time-consuming and laborious, and if the screw is too short, the applicable range will be limited, thus greatly reducing the applicability and speed of the clamp.

[0004] Therefore, it is necessary to develop a pressure sensor clamp structure that can be installed quickly to address the shortcomings of existing technologies. Utility Model Content

[0005] To address the problems mentioned in the background section, this invention provides a quick-installation pressure sensor clamp structure with the advantage of better connection sealing.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick-installation pressure sensor clamp structure, comprising a first clamp ring and a second clamp ring, a hinge connecting the bottoms of the first clamp ring and the second clamp ring, the lower ends of the first clamp ring and the second clamp ring being movably connected together by the hinge, a hinge frame being connected to the upper end of the outer surface of each of the first clamp ring and the second clamp ring, a connecting block and an adapter connecting piece being hinged inside the two hinge frames respectively, an adjusting component being threaded into the connecting block, and the other end of the adjusting component being movably engaged in the adapter connecting piece;

[0007] When the adjustment component is connected to the connecting block and the adapter connector, its axis is perpendicular to the axis of the first retaining ring and the second retaining ring as a whole. The pressure sensor is sleeved inside the first retaining ring and the second retaining ring as a whole. The connecting block and the adjustment component move with the adjustment component and drive the upper ends of the first retaining ring and the second retaining ring to move closer to each other through their respective hinge frames, and finally stick to the outer surface of the pressure sensor.

[0008] Furthermore, the adapter connector swings left and right along the interior of the hinge frame to which it is connected, the adjusting component follows the connecting block and swings left and right along the interior of the hinge frame to which it is connected, the adjusting component swings downward and finally engages with the interior of the adapter connector.

[0009] Furthermore, the adapter connector includes a connecting frame hinged to a corresponding hinge frame. The top of the connecting frame has a left-right through adapter groove. The bottom of the inner cavity of the adapter groove has an arc structure. The axis of the arc structure coincides with the axis of the connecting block. The connecting block and the connecting frame both have hinge holes located below the adapter groove. The hinge frame is connected to the connecting block and the connecting frame through the hinge holes.

[0010] Furthermore, a plurality of evenly distributed snap-fit ​​blocks are fixedly connected to the inner wall of the structure at the bottom of the inner cavity of the adapter groove. A snap-fit ​​groove is opened on the bottom of the outer surface of the snap-fit ​​block away from the connecting block. The adjustment component is snapped into the adapter connector through the snap-fit ​​groove.

[0011] Furthermore, the adjusting assembly includes an adjusting rod threaded into the connecting block, the end of the adjusting rod away from the adapter connector passing through the connecting block and connected to an anti-detachment block, the outer circumferential diameter of the anti-detachment block being larger than the outer circumferential diameter of the adjusting rod.

[0012] Furthermore, one end of the adjusting rod near the adapter connector passes through the connecting block and is fixedly connected to a linkage rod. A locking sleeve is movably sleeved on the outside of the linkage rod, and the locking sleeve is movably sleeved inside the adapter groove. The other end of the linkage rod passes through the locking sleeve and is fixedly connected to an adjusting knob.

[0013] Furthermore, the axes of the locking sleeve and the linkage rod coincide with the axis of the arc structure at the bottom of the inner cavity of the adapter groove. The locking sleeve is fixedly fitted with several evenly distributed linkage rings, which are movably embedded into the outer surface of the linkage rod. The bottom of the outer surface of the locking sleeve is fixedly connected with several evenly distributed locking blocks, and the lower end of the locking block is inserted into the snap-fit ​​groove between two adjacent snap-fit ​​blocks.

[0014] Furthermore, both the first and second retaining rings have clamp cavities inside, and anti-slip sleeves are fitted on the front and rear sides of the clamp cavity, with the inner wall of the anti-slip sleeves sealingly adhering to the sensor surface.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] Due to the adjustment component, this invention, in conjunction with the connecting block and the adapter connector, allows workers to quickly attach the first and second retaining rings to the outside of the pressure sensor. With the help of the hinge connector, the first and second retaining rings quickly adhere to both sides of the outer surface of the pressure sensor. Furthermore, with the coordination of the adjustment component and the adapter connector, the connecting block enables the two hinge brackets to quickly grip the first and second retaining rings, thereby achieving a rapid installation of the pressure sensor.

[0017] Due to the linkage ring, this invention ensures that the locking sleeve does not affect the rotation of the linkage rod, but can move axially with the linkage rod, thereby driving the adapter connector to move, so that the connecting block and the adapter connector move closer to each other, so that the first retaining ring and the second retaining ring can hold the sensor tightly through the hinge frame.

[0025] 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.

[0026] like Figures 1 to 6 As shown, this utility model provides a quick-installation pressure sensor clamp structure, including a first retaining ring 1 and a second retaining ring 2. A hinge 3 is connected between the bottoms of the first retaining ring 1 and the second retaining ring 2. The lower ends of the first retaining ring 1 and the second retaining ring 2 are movably connected together through the hinge 3. A hinge frame 4 is connected to the upper end of the outer surface of the first retaining ring 1 and the second retaining ring 2. A connecting block 5 and an adapter connector 6 are respectively hinged inside the two hinge frames 4. An adjustment component 7 is threaded inside the connecting block 5. The other end of the adjustment component 7 is movably engaged in the adapter connector 6.

[0027] When the adjusting component 7 is connected to the connecting block 5 and the adapter connector 6, its axis is perpendicular to the axis of the first retaining ring 1 and the second retaining ring 2 as a whole. The pressure sensor is sleeved inside the first retaining ring 1 and the second retaining ring 2 as a whole. The connecting block 5 and the adjusting component 7 move with the adjusting component 7, and through their respective corresponding hinge frames 4, the upper ends of the first retaining ring 1 and the second retaining ring 2 move closer to each other and finally stick to the outer surface of the pressure sensor.

[0028] Due to the setting of the adjustment component 7, with the cooperation of the connecting block 5 and the adapter connector 6, it is convenient for the operator to quickly attach the first retaining ring 1 and the second retaining ring 2 to the outside of the pressure sensor. With the cooperation of the hinge 3, the first retaining ring 1 and the second retaining ring 2 are quickly pressed against both sides of the outer surface of the pressure sensor. With the cooperation of the adjustment component 7 and the adapter connector 6, the two hinge frames 4 drive the first retaining ring 1 and the second retaining ring 2 to quickly hug the pressure sensor through the connecting block 5, thereby achieving the effect of rapid installation of the pressure sensor.

[0029] Among them, the adapter connector 6 swings left and right along the inside of the hinge frame 4 to which it is connected, the adjustment component 7 follows the connecting block 5 to swing left and right along the inside of the hinge frame 4 to which it is connected, the adjustment component 7 swings downward and finally snaps into the inside of the adapter connector 6.

[0030] The adapter connector 6 includes a connecting frame 61 hinged to the interior of a corresponding hinge frame 4. The top of the connecting frame 61 has a left-right through adapter groove 62. The bottom of the inner cavity of the adapter groove 62 is an arc structure. The axis of the arc structure coincides with the axis of the connecting block 5. The interior of both the connecting block 5 and the connecting frame 61 has a hinge hole 65 located below the adapter groove 62. The hinge frame 4 is connected to the connecting block 5 and the connecting frame 61 through the hinge hole 65.

[0031] Due to the setting of the adapter slot 62, the adjustment component 7 can be quickly swung into the adapter connector 6, thereby connecting the locking block 77 at the bottom of the locking sleeve 75 with the snap-fit ​​block 63 and snap-fit ​​slot 64 at the bottom of the inner cavity of the adapter slot 62.

[0032] Among them, a number of evenly distributed snap-fit ​​blocks 63 are fixedly connected to the inner wall of the structure at the bottom of the inner cavity of the adapter groove 62. A snap-fit ​​groove 64 is opened on the bottom of the outer surface of the snap-fit ​​block 63 away from the connecting block 5. The adjustment component 7 is snapped into the adapter connector 6 through the snap-fit ​​groove 64.

[0033] Due to the setting of the snap-fit ​​groove 64, by snapping with the locking block 77, the locking sleeve 75 can be locked with the connecting frame 61. Then, when the linkage rod 72 drives the locking sleeve 75 to move axially through the linkage ring 76, the adapter connector 6 can move axially at the same time and move away from or closer to the connecting block 5, thereby controlling the approach or distance of the upper ends of the first snap ring 1 and the second snap ring 2.

[0034] The adjusting component 7 includes an adjusting rod 71 threaded into the connecting block 5. The end of the adjusting rod 71 away from the adapter connector 6 passes through the connecting block 5 and is connected to an anti-detachment block 74. The outer diameter of the anti-detachment block 74 is larger than the outer diameter of the adjusting rod 71.

[0035] The adjusting rod 71 has one end that passes through the connecting block 5 and is fixedly connected to the linkage rod 72 near the adapter connector 6. The linkage rod 72 is movably sleeved with a locking sleeve 75, which is movably sleeved inside the adapter groove 62. The other end of the linkage rod 72 passes through the locking sleeve 75 and is fixedly connected to the adjusting knob 73.

[0036] Among them, the axis of the locking sleeve 75 and the linkage rod 72 coincides with the axis of the arc structure at the bottom of the inner cavity of the adapter groove 62. The locking sleeve 75 is fixedly sleeved with a number of evenly distributed linkage rings 76. The linkage rings 76 are movably embedded into the outer surface of the linkage rod 72. The bottom of the outer surface of the locking sleeve 75 is fixedly connected with a number of evenly distributed locking blocks 77. The lower end of the locking block 77 is inserted into the locking groove 64 between two adjacent locking blocks 63.

[0037] Due to the setting of the linkage ring 76, it can be ensured that the locking sleeve 75 will not affect the rotation of the linkage rod 72, but can move axially with the linkage rod 72, thereby driving the adapter connector 6 to move, so that the connecting block 5 and the adapter connector 6 are close to each other, so that the first retaining ring 1 and the second retaining ring 2 can hold the sensor tightly through the hinge frame 4.

[0038] The first retaining ring 1 and the second retaining ring 2 each have a retaining cavity 8 inside. Anti-slip sleeves 9 are fitted on both the front and rear sides of the retaining cavity 8. The inner wall of the anti-slip sleeves 9 is sealed and attached to the sensor surface.

[0039] Working principle and usage process of this utility model:

[0040] The first retaining ring 1 and the second retaining ring 2 are movably connected together by the hinge 3, and then simultaneously fitted onto the pressure sensor to be connected. Then, the adapter connector 6 and the adjustment component 7 are pulled at the same time, so that the first retaining ring 1 and the second retaining ring 2 continue to move closer through the corresponding hinge frame 4 and the connecting block 5 and the hinge frame 4, until the first retaining ring 1 and the second retaining ring 2 are pressed against the surface of the pressure sensor. Then, the adjustment component 7 is swung downward to enter the adapter groove 62, and the outer surface of the locking block 77 at the bottom of the locking sleeve 75 near the connecting block 5 is inserted into the locking groove 64 on the side of the locking block 63 away from the connecting block 5. At this time, the locking sleeve 75 is locked in the adapter groove 62 with the cooperation of the locking groove 64 and the locking block 77.

[0041] Then, by rotating the adjustment knob 73, the locking sleeve 75 can be prevented from restricting the linkage rod 72 with the help of the linkage ring 76. This allows the linkage rod 72 to drive the adjustment rod 71 to rotate. The rotation of the adjustment rod 71, with the help of the anti-detachment block 74, ensures that the connecting block 5 can always move left and right along the outside of the adjustment rod 71. This changes the distance between the connecting block 5 and the adapter connector 6, thereby pulling the upper ends of the first retaining ring 1 and the second retaining ring 2 closer together through the two hinge brackets 4. Under the restriction of the hinge connector 3, the two quickly clamp the pressure sensor.
