Description

Technical Field

[0001] The utility model relates to the technical field of measuring instrument protection, in particular to a legal measuring instrument anti-unsealing device. Background Art

[0002] Legal measuring instruments refer to instruments, appliances or systems used to measure goods, articles or services, which are subject to mandatory metrological management by the state. They include metrological standards, metrological verification instruments and metrological automation devices. Measuring instruments play a core role in metrological work and are the key tools and technical basis for ensuring the unification of national measurement values. Measuring instruments are widely used in many fields such as production, scientific research and daily life.

[0003] The metrological seal system prevents unauthorized persons from adjusting or tampering with the measuring instruments by sealing (anti-opening) the measuring instruments, thereby effectively ensuring the accuracy and reliability of the measurement results. At present, there is a lack of special devices for anti-opening of measuring instruments on the market. Most of them place the measuring instruments in the measuring instrument box and seal them with a seal strip to prevent opening. However, this anti-opening method is easy for criminals to open and steal or illegally adjust the instruments (adjust the internal structure or dial the meter display numbers) without being discovered, causing losses to the country. For this reason, we designed a legal metrological instrument anti-opening device to solve the above-mentioned technical problems. Utility Model Content

[0004] The purpose of the utility model is to provide a legal measuring instrument anti-unsealing device to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A device for preventing legal measuring instruments from being tampered with comprises a cabinet, a drawer, a drawer opening and a seal, wherein the cabinet is provided with a drawer opening, in which a drawer is housed, a cover is installed on the cabinet just above and just below the drawer, screws are installed on the cover, a holder is provided outside the screw, an anti-theft cap is installed on the holder, both ends of the seal are fixed by screws installed on the cover, a bearing is embedded on an outer panel of the drawer, and a limit assembly is installed in the middle of the bearing.

[0007] As a further solution of the utility model: the limit assembly includes an insertion rod, a limit stop rod and a knob, the limit stop rod is installed at one end of the insertion rod located in the drawer, and the knob is installed at one end of the insertion rod located outside the drawer.

[0008] As a further solution of the utility model: a through hole is provided on the drawer opening for the limit stopper to pass through, and a stopper passage opening is provided on one side of the through hole.

[0009] As a further solution of the utility model: two limit assemblies are symmetrically arranged on the drawer.

[0010] As a further solution of the utility model: a handle is installed on the outer end surface of the drawer, and the seal passes through the handle.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The utility model provides a cabinet body, a drawer and a limit assembly, wherein the drawer is fixed to the cabinet body through two limit assemblies, and the drawer can be opened and pulled out only when the two rotating limit assemblies are rotated to specified positions, thereby improving the protection capability of legal measuring instruments and reducing the risk of theft of legal measuring instruments.

[0013] The utility model arranges a cover body, a handle, a seal, a screw, a clamping seat and an anti-theft cap to cooperate with each other. The screws can fix the two ends of the seal in the cover body, and the screws cooperate with the clamping seat and the anti-theft cap to protect it from being opened. When the drawer is opened, the seal is immediately disconnected, so that it is convenient for personnel to find out whether the legal measuring instruments in the drawer are unsealed artificially, thereby avoiding theft or illegal adjustment.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-3 In the embodiment of the utility model, a legal measuring instrument anti-unsealing device comprises a cabinet 1, a drawer 2, a drawer opening 3 and a seal 6. The cabinet 1 is provided with a drawer opening 3, and the drawer 2 is installed in the drawer opening 3. A cover 4 is installed on the cabinet 1 just above and just below the drawer 2. Screws 7 are installed on the cover 4. A holder 8 is provided outside the screw 7. An anti-theft cap 9 is installed on the holder 8. Both ends of the seal 6 are fixed by screws 7 installed on the cover 4. A handle 5 is installed on the outer end surface of the drawer 2. The handle 5 runs through the middle of the seal 6. The setting of the handle 5 can facilitate the drawer 2 to be pulled out. The handle 5 runs through the middle of the seal 6 so that the seal 6 can be kept vertically and closely attached to the drawer 2 from top to bottom. Once the drawer 2 is pulled out, the seal 6 will be disconnected. The holder 8 and the anti-theft cap 9 adopt the license plate anti-theft cap and the corresponding base commonly used on the market, which belong to the existing mature products and will not be described here.

[0022] See also Figure 1 , Figure 4 and Figure 5 A bearing 10 is embedded on the outer panel of the drawer 2, and a limit assembly 11 is installed in the middle of the bearing 10. The limit assembly 11 includes an insertion rod 1101, a limit stop rod 1102 and a knob 1103. The limit stop rod 1102 is installed at one end of the insertion rod 1101 located in the drawer 2, and the knob 1103 is installed at the end of the insertion rod 1101 located outside the drawer 2. A through hole is provided on the drawer opening 3 for the limit stop rod 1102 to pass through, and a stop rod passage 12 is provided on one side of the through hole. Two limit assemblies 11 are symmetrically arranged on the drawer 2, so that the stop rod passages 12 corresponding to the two limit assemblies 11 face in opposite directions. The different rotation directions of the two limit assemblies 11 when opened can increase the difficulty of opening by criminals and improve the protection level.

[0023] The working principle of the utility model is:

[0024] When in use, put the legal measuring instrument into the drawer 2 and push the drawer 2 into the cabinet 1, then turn the two knobs 1103 respectively, the knob 1103 drives the limit stopper 1102 to rotate to a position that does not overlap with the stopper through hole 12 through the insertion rod 1101, so that the drawer 2 can be locked, and then the seal 6 is passed through the handle 5, and the two ends of the seal 6 are respectively set in the upper and lower covers 4, and the screws 7 on the cover 4 are rotated to fix the ends of the seal 6, and then the anti-theft cap 9 is pressed to The screws 7 are covered on the holder 8, and when criminals force open the drawer 2, the seal 6 will be destroyed, making it easier for personnel to identify whether the legal measuring instruments have been stolen or illegally adjusted. When the legal measuring instruments need to be taken out normally, special tools are needed to remove the anti-theft cap 9, and then unscrew the screws 7 to completely remove the seal 6, and then rotate the two knobs 1103 respectively, and rotate the limit stop rod 1102 to a position that coincides with the stop rod through-hole 12 through the knob 1103, so that the drawer 2 can be pulled out.

[0025] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
