Description

Technical Field

[0001] This utility model relates to the field of instrument and meter protection technology, and in particular to a shockproof shell for portable instruments and meters. Background Technology

[0002] Instruments and meters are tools or equipment used to detect, measure, observe, and calculate various physical quantities, material composition, and physical properties. Vacuum leak detectors, pressure gauges, length measuring instruments, microscopes, and multipliers all fall under the category of instruments and meters. In a broader sense, instruments and meters can also possess automatic control, alarm, signal transmission, and data processing functions. Examples include pneumatic and electric regulating instruments used in the automatic control of industrial production processes, as well as distributed control systems. Portable instruments and meters are widely used in industrial testing, environmental monitoring, and medical diagnosis. Due to their frequent movement and carrying, they are susceptible to impacts such as collisions and drops during use and transportation.

[0003] In the existing technology, some instrument housings are protected by rubber or silicone sleeves. Although this method can provide a certain cushioning effect, the rubber sleeve and the housing are usually loosely fitted, which can easily fall off or shift during long-term use, resulting in unstable protection. Moreover, the rubber sleeve can only protect the surface of the housing and cannot effectively absorb and disperse the impact energy transmitted to the inside, thus having limited protection for precision instruments. The existing housing structure lacks effective cushioning design at the seams, and lateral impacts can easily cause the housing to deform or crack. Utility Model Content

[0004] The technical problems to be solved by this utility model are: 1. The rubber sleeve and the outer shell are usually loosely fitted, which is easy to fall off or shift during long-term use, resulting in unstable protection; 2. The rubber sleeve can only protect the surface of the outer shell and cannot effectively absorb and disperse the impact energy transmitted to the inside, thus having limited protection effect on precision instruments; 3. The existing outer shell structure lacks effective buffer design at the seams, and lateral impacts can easily cause the shell to deform or crack.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a portable instrument anti-collision shell, which includes an upper shell and a lower shell;

[0006] An elastic strip is provided between the upper shell and the lower shell, and an inner liner shell is provided on the inner wall between the upper shell and the lower shell, with an elastic material laid between the inner liner shell and the upper shell or the lower shell.

[0007] As a preferred embodiment of the portable instrument anti-collision shell of this utility model, an observation window is installed on the upper shell.

[0008] As a preferred embodiment of the portable instrument anti-collision shell of this utility model, wherein: the edge of the upper shell or the lower shell protrudes to form a retaining strip, and the elastic strip is located between the two retaining strips of the upper shell or the lower shell.

[0009] As a preferred embodiment of the portable instrument anti-collision shell of this utility model, the card strip has a card groove, and the elastic strip has a protrusion corresponding to the card groove, the protrusion slidingly connected to the inner wall of the card groove.

[0010] As a preferred embodiment of the portable instrument anti-collision shell of this utility model, a gap is left between the inner shell and the retaining strip.

[0011] As a preferred embodiment of the portable instrument anti-collision shell of this utility model, the upper shell outer wall is fixedly connected to a first fixing block, the first fixing block having a first through hole, the lower shell outer wall is fixedly connected to a second fixing block, the second fixing block having a second through hole, a screw passing through the first through hole and the second through hole, and nuts threadedly connected to both ends of the screw.

[0012] As a preferred embodiment of the portable instrument anti-collision shell of this utility model, two fixing rings are fixedly connected to the screw.

[0013] As a preferred embodiment of the portable instrument anti-collision shell of this utility model, the elastic material is composed of a layer of elastic small balls, one end of which is fixedly connected to the upper shell or the lower shell, and the other end of which is fixedly connected to the inner lining shell.

[0014] As a preferred embodiment of the portable instrument anti-collision shell of this utility model, a fixing tube passes through the lower shell, and the outer wall of the fixing tube is fixedly connected to the lower shell, with a gap between the outer wall of the fixing tube and the inner lining shell of the lower shell.

[0015] As a preferred embodiment of the portable instrument anti-collision shell of this utility model, the outer end of the fixing tube protrudes from the outer wall of the lower shell.

[0016] The beneficial effects of this utility model are as follows: This utility model forms a multi-layer buffer and protection structure through elastic strips and elastic materials. The elastic strips provide lateral buffering, the elastic materials provide radial buffering, and the gap between the inner shell and the retaining strip provides displacement buffering space.

[0017] When the upper or lower shell is subjected to external impact, the elastic strip first absorbs the impact energy from the side or longitudinal direction, the elastic ball undergoes elastic deformation, absorbs and disperses the impact energy, and at the same time, the inner shell is displaced within the gap range, further dissipating the impact energy and preventing the impact force from acting directly on the instruments inside the inner shell, thereby effectively protecting the safety of the instruments.

Detailed Implementation

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] Example 1, referring to Figures 1-4 This embodiment provides a portable instrument and meter anti-collision housing, including an upper housing 1 and a lower housing 2;

[0027] An elastic strip 11 is provided between the upper shell 1 and the lower shell 2, and an inner liner shell 12 is provided on the inner wall between the upper shell 1 and the lower shell 2, and an elastic material 13 is laid between the inner liner shell 12 and the upper shell 1 or the lower shell 2.

[0028] In this preferred embodiment, the upper housing 1 and the lower housing 2 are two opposing housing components constituting the main structure of the outer shell, forming a closed space to accommodate instruments. The upper housing 1 and the lower housing 2 are fixed by a detachable connection, facilitating the installation and maintenance of the instruments. The upper housing 1 and the lower housing 2 can be made of rigid plastic or lightweight metal materials, such as ABS plastic or aluminum alloy, ensuring structural strength while reducing weight.

[0029] Furthermore, the elastic strip 11 is an elastic buffer element disposed at the joint between the upper shell 1 and the lower shell 2, used to absorb impact energy from the side or longitudinal direction. When the upper shell 1 and the lower shell 2 are subjected to a lateral impact, the elastic strip 11 first undergoes elastic deformation, absorbing part of the impact energy and reducing the transmission of the impact force to the interior of the upper shell 1 and the lower shell 2. The elastic strip 11 can be made of elastic materials such as rubber, silicone, or polyurethane.

[0030] Furthermore, the inner shell 12 is a shell structure disposed on the inner wall of the upper shell 1 or the lower shell 2, used to directly support and protect the instrument. The inner shell 12 is connected to the outer shell by an elastic material 13. The inner shell 12 can undergo slight displacement when the outer shell is impacted, further absorbing the impact energy. The inner shell 12 can be made of plastic or lightweight metal materials, and its shape matches the shape of the instrument. The elastic material 13 is an elastic buffer layer laid between the inner shell 12 and the outer shell, used to absorb and disperse impact energy. The elastic material 13 is evenly distributed between the outer surface of the inner shell 12 and the inner surface of the upper shell 1 or the lower shell 2. When the upper shell 1 or the lower shell 2 is impacted, the elastic material 13 undergoes elastic deformation, converting the impact energy into elastic potential energy, preventing the impact force from acting directly on the instrument.

[0031] A multi-layered buffer and protective structure is formed by the elastic strip 11 and the elastic material 13. When the upper shell 1 or the lower shell 2 is subjected to external impact, the elastic strip 11 first absorbs the impact energy from the side or longitudinal direction, and the elastic material 13 further absorbs and disperses the impact energy transmitted to the interior of the upper shell 1 or the lower shell 2, so as to avoid the impact force directly acting on the instruments inside the inner shell 12, thereby effectively protecting the safety of the instruments.

[0032] Example 2, refer to Figures 1-6 This embodiment is based on the previous embodiment, but differs from the previous embodiment in that...

[0033] Reference Figure 1 An observation window 14 is installed on the upper housing 1.

[0034] In this preferred embodiment, the observation window 14 refers to a transparent window structure disposed on the upper housing 1, used to facilitate the user's observation of the instrument's display readings. The observation window 14 is made of a transparent material, such as tempered glass or transparent plastic, and is connected to the upper housing 1 by sealant or clips to ensure airtightness. The user can directly observe the instrument's display readings through the observation window 14 without opening the outer housing, making it more convenient to use and avoiding wear and tear on the instrument caused by frequent opening and closing of the upper housing 1.

[0035] Reference 2- Figure 4The upper housing 1 or the lower housing 2 has protrusions on its edge to form a retaining strip 15, and the elastic strip 11 is located between the two retaining strips 15 of the upper housing 1 or the lower housing 2.

[0036] In this preferred embodiment, the retaining strip 15 is integrally formed with the upper housing 1 or the lower housing 2, and a groove-shaped space is formed between the two retaining strips 15 to accommodate the elastic strip 11. The retaining strip 15 can limit the elastic strip 11, prevent the elastic strip 11 from displacing or falling off when subjected to impact, and ensure the stability of the cushioning effect.

[0037] Reference 2- Figure 4 The card strip 15 has a card groove 151, and the elastic strip 11 has a protrusion 111 corresponding to the card groove 151. The protrusion 111 is slidably connected to the inner wall of the card groove 151.

[0038] Preferably, in this embodiment, the slot 151 extends along the length of the strip 15, and the protrusion 111 matches the shape of the slot 151. During installation, the protrusion 111 of the elastic strip 11 is aligned with the slot 151, and the strip is slid along the direction of the slot 151 to complete the installation. This sliding connection method facilitates the installation and replacement of the elastic strip 11, while ensuring the positional stability of the elastic strip 11 during operation, and improving the maintenance convenience of the upper housing 1 or the lower housing 2.

[0039] Reference 2- Figure 4 A gap is left between the inner lining shell 12 and the retaining strip 15.

[0040] Preferably, in this embodiment, a gap is left between the inner liner shell 12 and the retaining strip 15. The width of this gap is determined according to the size of the upper shell 1 or the lower shell 2 and the protection requirements, and is generally 1-5 mm. This gap provides a buffer space for the inner liner shell 12. When the upper shell 1 or the lower shell 2 is impacted, the inner liner shell 12 can shift within a certain range, further absorbing the impact energy and enhancing the protective effect. At the same time, this gap can also prevent the inner liner shell 12 from directly contacting the retaining strip 15 and causing wear.

[0041] Reference Figure 5 The outer wall of the upper housing 1 is fixedly connected to the first fixing block 21, which has a first through hole 211. The outer wall of the lower housing 2 is fixedly connected to the second fixing block 22, which has a second through hole 221. A screw 23 passes through the first through hole 211 and the second through hole 221, and nuts 24 are threaded to both ends of the screw 23.

[0042] In this preferred embodiment, the first fixing block 21 is integrally formed with the upper housing 1 or fixedly connected by bolts, and the second fixing block 22 is integrally formed with the lower housing 2 or fixedly connected by nuts 24. When the upper housing 1 and the lower housing 2 are mated, the first fixing block 21 and the second fixing block 22 are aligned with each other, and the first through hole 211 and the second through hole 221 form a through channel. By tightening the nuts 24, the first fixing block 21 and the second fixing block 22 can be brought closer together, realizing the connection between the upper housing 1 and the lower housing 2, while facilitating disassembly and maintenance, and is more reliable than the traditional snap-fit ​​connection method. Preferably, multiple first fixing blocks 21, second fixing blocks 22, screws 23 and nuts 24 are provided to install and fix the upper housing 1 and the lower housing 2, so that the force between the upper housing 1 and the lower housing 2 is uniform.

[0043] Reference Figure 5 Two fixing rings 25 are fixedly connected to the screw 23.

[0044] In this preferred embodiment, the two retaining rings 25 are located on the outer sides of the first retaining block 21 and the second retaining block 22, respectively. The retaining rings 25 are fixedly connected to the screw 23 by welding or interference fit. The retaining rings 25 are used to limit the axial movement of the first retaining block 21 or the second retaining block 22, preventing the nuts 24 from being tightened too much, which would cause the elastic strip 11 to be squeezed and deformed, losing its elasticity and weakening the buffering effect. After the screw 23 is tightened with two nuts 24 at one end, the nuts 24 will limit the screw 23 and prevent the screw 23 from slipping.

[0045] Reference 2- Figure 4 The elastic material 13 is composed of a layer of elastic small balls 131. One end of the elastic small ball 131 is fixedly connected to the upper shell 1 or the lower shell 2, and the other end of the elastic small ball 131 is fixedly connected to the inner lining shell 12.

[0046] In this embodiment, the elastic balls 131 are preferably made of elastic materials such as rubber, silicone, or polyurethane, and generally have a diameter of 3-10 mm. Multiple elastic balls 131 are evenly distributed to form an elastic buffer layer. One end of each elastic ball 131 is fixedly connected to the inner wall of the outer shell by bonding or vulcanization, and the other end is fixedly connected to the outer wall of the inner lining shell 12 by bonding or vulcanization.

[0047] Furthermore, the elastic spheres 131 provide uniform elastic support, while the gaps between adjacent elastic spheres 131 facilitate the dispersion and absorption of impact energy. When the shell is impacted, the elastic spheres 131 undergo elastic deformation, absorbing the impact energy. Simultaneously, the gaps between adjacent elastic spheres 131 allow for a certain degree of displacement, further dispersing the impact energy. Compared to traditional monolayer elastic materials, this structure offers better cushioning and energy absorption capabilities.

[0048] Furthermore, when the outer shell is impacted, the elastic spheres 131 undergo elastic deformation, converting the impact energy into stored elastic potential energy, which is then slowly released. Because there are gaps between the elastic spheres 131, the impact force is not concentrated in a single area, but rather dispersed through the coordinated deformation of multiple elastic spheres 131. Compared to traditional solid foam or rubber pads, this structure offers better energy absorption efficiency and a longer service life.

[0049] Reference Figure 6 A fixing tube 26 passes through the lower housing 2, and the outer wall of the fixing tube 26 is fixedly connected to the lower housing 2. A gap is left between the outer wall of the fixing tube 26 and the inner lining housing 12 of the inner wall of the lower housing 2.

[0050] The outer end of the fixed tube 26 protrudes from the outer wall of the lower housing 2.

[0051] In this preferred embodiment, the fixing tube 26 is fixedly connected to the lower housing 2 by welding or integral molding. The inner diameter of the fixing tube 26 is determined according to the size of the cable or connector. The gap width between the outer wall of the fixing tube 26 and the inner housing 12 is generally 1-3 mm. This gap avoids direct contact between the fixing tube 26 and the inner housing 12. When the outer housing is impacted, the inner housing 12 can move freely, ensuring that the cushioning effect of the inner housing 12 is not affected. The fixing tube 26 is used to pass through cables or connectors, facilitating the connection between instruments and external equipment. The gap design avoids direct contact between the fixing tube 26 and the inner housing 12, and the outer end of the fixing tube 26 protrudes from the outer wall of the lower housing 2. The protruding fixing tube 26 facilitates the access of cables or connectors. In one embodiment, the protruding length of the outer end of the fixing tube 26 is generally 5-15 mm, which is convenient for operation, does not affect the overall aesthetics of the outer housing, and also protects the cables or connectors inside the fixing tube 26.
