Description

Technical Field

[0001] The invention belongs to the field of sensors, and in particular relates to a sensor loading and unloading tool used in a narrow space. Background Art

[0002] Sensors are widely used in aerospace, aviation, weapons and equipment and other fields. With the continuous development of miniaturization and integration of products in various fields, the space left for sensor installation and operation has become very tight, which will make sensor installation difficult. In this case, it is necessary to disassemble the parts of the measured component that affect the operation before installing the sensor.

[0003] Common sensor shapes include Figure 1 As shown in the figure, the threaded section at the bottom of the "hexagonal" fastening end below is connected to the measured component through a thread (the cylindrical section below the "hexagonal" structure is provided with a thread). The "hexagonal" fastening end is mainly for the convenience of using a wrench to install and remove the sensor by screwing. However, in certain scenarios, the wrench cannot be put into the working space for direct operation because the size of the wrench clamping part or the handle exceeds the allowable working space around the "hexagonal" fastening end.

[0004] In addition, if a conventional hexagonal sleeve with a unique barrel diameter is selected for disassembly, since the size of the "hexagonal" fastening end is smaller than the outer diameter of the sensor, and the barrel diameter of the hexagonal sleeve must be larger than the outer diameter of the sensor to allow the sensor to be inserted, the conventional hexagonal sleeve cannot avoid the outer diameter of the sensor and directly act on the "hexagonal" fastening end to perform disassembly and assembly operations.

[0005] Moreover, the electrical interfaces of some sensors extend in a direction perpendicular to the sensor body, causing interference between the conventional hexagonal socket and the electrical interface, making it impossible for the sensor to be inserted into the hexagonal socket. In order to use the hexagonal socket, the electrical interface needs to be disassembled. Sometimes, the relevant electrical interface cannot be disassembled, and the sensor needs to be redesigned or the relevant measuring points can only be cancelled, resulting in performance loss of sensor-related products.

[0006] The above situation results in a lot of time and labor costs required when installing and removing the sensor, which brings inconvenience to sensor-related applications. Summary of the invention

[0007] In view of this, the present invention discloses a sensor loading and unloading tool for a narrow space, which respectively arranges protruding ends and clamping modules at both ends of an outer sleeve to avoid the problem of horizontal arrangement of the clamping part and the handle part of a traditional wrench, which requires a larger space when used; it can be operated in a narrow space of only 8 cm around the "hexagonal" fastening end of the sensor; and a notch is provided on the side wall of the outer sleeve to avoid the problem of interference of the sensor electrical interface with the outer sleeve; the loading and unloading tool is convenient for installation and disassembly of sensors in a narrow space, and is also convenient for daily use, simple to maintain, and low in cost.

[0008] The sensor loading and unloading tool for a narrow space comprises: an outer sleeve, one end of which is provided with a protruding end, which is used to cooperate with the clamping part of a wrench to generate a torque load applied to the outer sleeve;

[0009] An annular clamping module can be detachably arranged on the inner side of the other end of the outer sleeve for fastening the fastening end of the sensor; and the clamping module itself is a detachable modular structure;

[0010] The inner diameter of the clamping module is smaller than the inner diameter of the outer sleeve;

[0011] When in use, the outer sleeve is firstly sleeved with the sensor, and then the clamping module is installed.

[0012] Preferably, tooth-shaped grooves distributed circumferentially are provided at the location where the clamping module is provided on the inner side of the outer sleeve;

[0013] The clamping module comprises a plurality of locking blocks of the same shape, a groove is provided on the back of the locking block, and each locking block corresponds to each toothed slot of the outer sleeve one by one;

[0014] The toothed slot is provided with a protruding structure corresponding to the groove, and the groove cooperates with the protruding structure to fix the locking block to the toothed slot.

[0015] Preferably, a limiting boss is provided at one end of the toothed slot facing the protruding end, and the distance from the limiting boss to the bottom of the outer sleeve is consistent with the height of the locking block.

[0016] Preferably, a notch communicating with the bottom is provided on the side wall of the outer sleeve to provide a placement space for the electrical interface end of the sensor.

[0017] Preferably, the length of the notch is less than one third of the length of the outer sleeve.

[0018] Preferably, the protruding end is hexagonal or quadrangular.

[0019] Preferably, the outer sleeve and the clamping module are both made of stainless steel.

[0020] Beneficial Effects

[0021] (1) The sensor loading and unloading tool of the present invention changes the horizontal arrangement of the clamping part and the handle part of the traditional wrench by means of a protruding structure suitable for a wrench arranged on the top of the outer sleeve and a clamping module arranged on the inner side of the bottom thereof, so that the handle part and the clamping part are arranged vertically, thereby solving the problem that the clamping part or the handle part of the wrench cannot enter a narrow working space to install and disassemble the "hexagonal" fastening end of the sensor.

[0022] (ii) The clamping module of the sensor loading and unloading tooling of the present invention is arranged in the outer sleeve, and the clamping module includes a plurality of locking blocks of the same shape. The locking block is used to clamp the "hexagonal" fastening end of the sensor, and the outer sleeve is used to wrap the outer diameter of the sensor. This can solve the problem that the pressure sensor cannot be installed and disassembled using a traditional hexagonal sleeve when the "hexagonal" fastening end is smaller than the outer diameter of the sensor.

[0023] (III) The outer sleeve side wall of the sensor loading and unloading tool of the present invention is provided with a notch connected to the bottom, so as to solve the interference problem when the electrical interface end of the sensor and the main body are arranged vertically, so that the loading and unloading tool can be applied to sensors in which the electrical interface end and the sensor main body are arranged horizontally, and can also be applied to sensors in which the electrical interface end and the sensor main body are arranged vertically, thereby expanding the application scope of the loading and unloading tool.

[0024] (IV) The sensor loading and unloading tooling of the present invention has a groove on the back of the locking block, and a clamping fit with the raised structure on the toothed slot, so that the locking block and the toothed slot are fastened, thereby improving the effective transmission of the torque load during the sensor installation and disassembly process.

[0025] (V) The limiting boss provided on the toothed slot of the sensor loading and unloading tool of the present invention limits the axial movement of the locking block, increases the fixing degree of the locking block, and improves the stability of the locking block when fastening the sensor.

[0031] The present invention will be further described below in conjunction with the accompanying drawings: It should be emphasized that the embodiments described in the present invention are illustrative rather than restrictive, and therefore the present invention is not limited to the embodiments described in the specific implementation manners, and any other implementation manners derived by those skilled in the art based on the technical solution of the present invention also fall within the scope of protection of the present invention.

[0032] Example 1

[0033] like Figure 1-3 As shown, a sensor loading and unloading tool for a narrow space includes an outer sleeve 1 and a detachable clamping module. A protruding end 4 is provided at one end of the outer sleeve 1 for cooperating with the clamping part of a wrench to apply a torque load to the outer sleeve 1; a clamping module is provided inside the other end of the outer sleeve 1 for cooperating with the fastening end of the sensor. The clamping module is annular and detachable; the inner diameter of the clamping module is smaller than the inner diameter of the outer sleeve 1. The protruding end 4 and the clamping module of the loading and unloading tool are respectively arranged at the two ends of the outer sleeve 1. By changing the way that the clamping part and the handle part of the traditional wrench are arranged horizontally, that is, the clamping part and the handle part of the wrench are arranged vertically, the outer sleeve 1 can be smoothly placed vertically in the narrow working space around the "hexagonal" fastening end of the sensor, solving the problem that the traditional wrench cannot enter the working space. After the clamping module of the outer sleeve 1 is matched with the fastening end of the sensor, the clamping part of the wrench is matched with the protruding end 4 of the loading and unloading tool, and the wrench is rotated to transmit the torque load to the fastening end of the sensor, thereby realizing the installation and removal of the sensor.

[0034] Example 2

[0035] On the basis of Example 1, further. The clamping module includes a plurality of locking blocks 3 of the same shape, each of the locking blocks 3 corresponds to each toothed slot 2 of the outer sleeve 1, a groove is provided on the back of the locking block 3, and a protruding structure is provided on the toothed slot 2 corresponding to the groove, and the groove and the protruding structure cooperate to fix the locking block 3 to the toothed slot 2. The locking block 3 is used to clamp the "hexagonal" fastening end of the sensor, and the outer sleeve 1 is used to wrap the sensor, which can solve the problem that the sensor cannot be installed and removed using a traditional hexagonal sleeve when the "hexagonal" fastening end is smaller than the outer diameter of the sensor. When in use, after the outer sleeve 1 is sleeved with the sensor, the locking block 3 is installed on the outer sleeve to form a clamping module.

[0036] As an example, the locking block 3 has two grooves, and the toothed slot 2 is provided with two protruding structures, so that the locking block 3 is fastened to the toothed slot 2, and the effective transmission effect of the torque load is improved when the sensor is installed and removed.

[0037] Furthermore, a limiting boss is provided at one end of the toothed slot 2 toward the protruding end 4, and the distance from the limiting boss to the bottom of the outer sleeve 1 is consistent with the height of the locking block 3, so as to prevent the locking block 3 from being subjected to inconsistent torque loads due to inconsistent heights of the limiting boss, thereby affecting the stability of the locking block 3 relative to the toothed slot 2 and being detrimental to the stability of the clamping module acting on the sensor.

[0038] Example 3

[0039] On the basis of Embodiment 1 or 2, further, a notch connected to the bottom is provided on the side wall of the outer sleeve 1 to provide a placement space for the electrical interface end of the sensor. The provision of the notch solves the interference problem caused when the electrical interface end of the sensor and the main body are arranged vertically, so that the loading and unloading tool can be applied to sensors in which the electrical interface end and the sensor main body are arranged horizontally, and can also be applied to sensors in which the electrical interface end and the sensor main body are arranged vertically, thereby expanding the scope of application of the loading and unloading tool.

[0040] Furthermore, the length of the notch is no more than one third of the total length of the outer sleeve 1, so as to ensure that the outer sleeve 1 has a certain rigidity and will not deform when transmitting torque load.

[0041] As an example, the protruding end 4 is hexagonal or quadrangular, which further improves the application scope of the loading and unloading tool.

[0042] As an example, the outer sleeve 1 and the locking block 3 are both made of stainless steel, which can reduce the manufacturing cost.

[0043] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by any technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
