Description

Technical Field

[0001] The utility model relates to the field of sensors, in particular to a sensor protection shell. Background Art

[0002] A sensor is a detection device that can sense the information to be measured and transform the sensed information into an electrical signal or other required form of information output according to a certain rule to meet the requirements of information transmission, processing, storage, display, recording, and control. When in use, a protection shell is usually arranged outside the sensor. The protection shell is usually formed by connecting two upper and lower shells through screws. Most of them adopt the screw connection method, and the screws are usually directly exposed outside. Affected by water vapor in the air, etc., they will age and corrode, making it difficult for the screws to separate from the shell, and the disassembly is very difficult. Moreover, the screw connection method is also prone to the situation of slipping threads, resulting in the screws being unable to separate from the shell normally. For this reason, we have designed a sensor protection shell. Content of the Utility Model

[0003] To solve the technical problem that the screw connection method causes aging and corrosion, making it difficult for the screws to separate from the shell and the disassembly is very difficult, the utility model provides a sensor protection shell.

[0004] The utility model is realized by adopting the following technical solutions: A sensor protection shell includes a base. An installation seat is arranged above the interior of the base, and the sensor is fixed above the installation seat. A fixed frame is integrally formed above the base. A fixed shell is welded to the right side above the base, and the fixed shell is welded to the fixed frame. The front and rear ends inside the fixed shell are thickened to form thickened parts, and clamping grooves are formed on the sides of the thickened parts;

[0005] A movable shell is slidably arranged left and right above the base. The movable shell has a U-shaped structure, and plugging elastic members are arranged at both ends on the right side of the movable shell. The plugging elastic members are plugged into the clamping grooves, and the inner walls of the front and rear sides of the movable shell are closely attached to the outer surface of the fixed frame. A cover plate is welded above the movable shell, and the cover plate is closed above the fixed shell.

[0006] As a further improvement of the above solution, the outermost inner wall edge of the clamping groove is rounded to form a widened opening. The design of the widened opening increases the opening at the entrance of the clamping groove and is an arc surface structure, thereby facilitating the plugging elastic member to be plugged into the clamping groove.

[0007] As a further improvement of the above solution, three equally spaced locking holes are formed on the left surface of the fixed frame. The outer circle of the locking hole is rounded to form an arc surface, increasing the inner diameter outside the locking hole, and its overall inner diameter gradually decreases from outside to inside;

[0008] The inner wall of the movable shell is provided with three locking sleeves distributed at equal intervals, and the locking sleeve is composed of a plurality of elastic arc plates distributed in an annular shape. The locking sleeve is inserted into the locking hole. The locking sleeve has a tendency to spread outward. After being inserted into the locking hole, the locking sleeve will gradually come into contact with each other, thereby increasing the resistance between the locking hole and the locking hole, thereby increasing the firmness of the connection between the two.

[0009] As a further improvement of the above solution, side slots are provided on the front and rear sides of the fixed frame, and the inner wall of the movable shell is provided with side elastic parts, which are inserted into the side slots to increase the resistance between the two sides of the movable shell and the fixed frame, thereby improving the connection strength.

[0010] As a further improvement of the above solution, a protruding plate is provided on the lower surface of the cover plate, and the outer length and width of the protruding plate are consistent with the length and width of the rectangular structure formed by the inner walls of the fixed shell and the movable shell. The protruding plate can be fitted inside the fixed frame and the movable frame, thereby improving the sealing performance;

[0011] There is a 5-10mm gap between the top of the thickened portion and the top of the fixed shell. The thickness of the protruding plate is the same as the height from the top of the thickened portion to the top of the fixed shell, and will not interfere with the thickened portion.

[0012] As a further improvement of the above solution, two through ports are provided on the right side of the fixed shell, and a plug-in port is provided on the left end of the movable shell for connecting the sensor to the data cable.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The utility model divides the protective shell into three parts: a base, a fixed shell and a movable shell. A fixed frame and a fixed shell are arranged above the base. The cover plate is fixed on the top of the movable shell. The movable shell can be plugged and fixed on the fixed frame and the fixed shell from left to right, so that it can be quickly fixed. No corresponding tools are needed during the entire installation process, and it can be quickly installed and disassembled.

[0015] 2. By providing the side elastic parts, the plug-in elastic parts and the locking sleeve, the resistance between the movable shell and the fixed shell and the fixed frame can be increased, so that a larger force is required to disassemble them, thereby improving the firmness of the connection and preventing them from falling off.

The design of the widened opening increases the opening at the entrance of the clamping groove 23 and has an arc surface structure, thereby facilitating the plug-in elastic part 33 to be inserted into the clamping groove 23.

[0028] The left side surface of the fixing frame 5 is provided with three locking holes 52 which are equally spaced. The outer rounded corners of the locking holes 52 are designed to form an arc surface, which increases the inner diameter of the outer side of the locking holes 52, and the overall inner diameter gradually decreases from the outside to the inside.

[0029] The inner wall of the movable shell 3 is provided with three locking sleeves 31 distributed at equal intervals, and the locking sleeve 31 is composed of a plurality of elastic arc plates distributed in a ring shape. The locking sleeve 31 is inserted into the locking hole 52. The locking sleeve 31 has a tendency to spread outward. After being inserted into the locking hole 52, the locking sleeve 31 will gradually come into contact with each other, thereby increasing the resistance between the locking hole 52 and the locking hole 52, thereby increasing the firmness of the connection between the two.

[0030] Side slots 51 are provided on both the front and rear sides of the fixed frame 5, and side elastic members 32 are provided on the inner wall of the movable shell 3. The side elastic members 32 are inserted into the side slots 51, which increases the resistance between the two sides of the movable shell 3 and the fixed frame 5 and improves the connection strength.

[0031] The lower surface of the cover plate 4 is provided with a protruding plate 41, the outer length and width of the protruding plate 41 are consistent with the length and width of the rectangular structure formed by the inner walls of the fixed shell 2 and the movable shell 3, and the protruding plate 41 can be fitted inside the fixed frame 5 and the movable frame, thereby improving the sealing performance;

[0032] There is a 5-10 mm gap between the top of the thickened portion 22 and the top of the fixed shell 2 . The thickness of the protruding plate 41 is the same as the height from the top of the thickened portion 22 to the top of the fixed shell 2 , and will not interfere with the thickened portion 22 .

[0033] Two through ports 21 are arranged on the right side of the fixed shell 2, and a plug-in port is arranged on the left end of the movable shell 3 for connecting the sensor with a data line.

[0034] The implementation principle of a sensor protection shell in the embodiment of the present application is as follows: the side elastic member 32 and the plug-in elastic member 33 are elastic metal members with a convex structure, and a fixing hole is provided on the base 1, which can be used to fix on the required installation equipment. When installing, the sensor is placed on the mounting seat above the base 1 and fixed by screws, and then the movable shell 3 is plugged into the front and rear sides of the outside of the fixed frame 5 from left to right. When the movable shell 3 is at the rightmost end, the plug-in elastic member 33 of the movable shell 3 will be plugged into the clamping groove 23 of the fixed shell 2, and the three locking sleeves 31 are respectively plugged into the locking holes 52, thereby completing the installation of the movable shell 3, and the installation of the entire protection shell can be completed;

[0035] The protective shell is divided into three parts, namely, a base 1, a fixed shell 2 and a movable shell 3. A fixed frame 5 and a fixed shell 2 are arranged above the base 1. The cover plate 4 is fixed on the top of the movable shell 3. The movable shell 3 can be plugged and fixed on the fixed frame 5 and the fixed shell 2 from left to right, so that the movable shell 3 can be quickly fixed. No corresponding tools are needed during the entire installation process, so the movable shell 3 can be quickly installed and disassembled.

[0036] By providing the side elastic member 32, the plug-in elastic member 33 and the locking sleeve 31, the resistance between the movable shell 3 and the fixed shell 2 and the fixed frame 5 can be increased, so that a greater force is required to disassemble them, thereby improving the firmness of the connection and preventing them from falling off.

[0037] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope 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.
