Description

Technical Field

[0001] The utility model relates to the technical field of density meter equipment, in particular to a shock-resistant density meter. Background Art

[0002] Density meters are usually used to measure the density of liquids or gases and display it in the form of pressure. Density pressure meters are widely used in industrial production and scientific research.

[0003] In the prior art, such as the Chinese patent number CN208091850U, "A shock-resistant density meter", includes a shell of the shock-resistant density meter, a base arranged in the shell, a Baden tube, an end seat, a temperature compensation element, a movement, a pointer, and a dial. The movement includes upper and lower plates and a central shaft clamped by the plates and a transmission gear set. The output gear in the transmission gear set is a fan-shaped gear, which is connected to the outer extending ends of the upper and lower plates and a pull rod pivot. It is characterized in that a torsion spring fixing part is provided on the pull rod on one side close to the pivot connection, and a torsion spring spacer is provided on the other side of the pull rod. A torsion spring is sleeved on the torsion spring fixing part, and the two ends of the torsion spring clamp the pivot from both sides of the pivot and extend to both sides of the torsion spring spacer and clamp the torsion spring spacer.

[0004] In the above technology, although the pull rod returns to its original position under the action of the torsion spring when the vibration generated by the switch operation is reduced, thereby avoiding the influence of the pointer swing on the docking point during vibration, the changes in the surrounding environment and the different vibrations generated will have a great impact on the internal density meter. Although the density meter can resist ordinary vibrations from the inside, it may explode when encountering greater external vibrations. Even if the anti-vibration function is strengthened from the inside, it will not help, causing great trouble to technicians and maintenance personnel. Utility Model Content

[0005] The purpose of the utility model is to solve the problem in the prior art that changes in the surrounding environment and different vibrations generated will have a great impact on the internal density meter. Although the density meter can be shock-resistant to ordinary vibrations from the inside, it may cause the density meter to explode when encountering greater external vibrations. Even if the shock-resistant function is strengthened from the inside, it is of no avail, which causes great trouble to technicians and maintenance personnel.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions: a shock-resistant density meter, comprising: a density meter body, a plurality of springs are fixedly installed on the outer surface of the density meter body, a protective shell is fixedly installed on the other side of the plurality of springs, two connecting blocks are fixedly installed on both sides of the protective shell, two support blocks are fixedly installed on one side of the two connecting blocks, the plurality of support blocks are evenly divided into two groups, an upper support rod is fixedly installed inside each group of support blocks, two upper fixed plates are fixedly installed on the bottom of the two upper support rods, and linkage blocks are fixedly installed on the bottom of the plurality of upper fixed plates.

[0007] The technical effect of adopting the above further scheme is: the spring pair on the inner wall of the protective shell has a direct anti-seismic effect on the shaking density meter body, and the pressure exerted on the protective shell is transferred to the upper support rod and the upper fixed plate and then to the linkage block by setting a connecting block.

[0008] As a preferred embodiment, multiple lower fixed plates are fixedly installed on the bottom of the linkage block, and the multiple lower fixed plates are evenly divided into two groups. The bottom of each group of lower fixed plates is fixedly connected to a lower support rod, and two sliders are fixedly installed on both sides of the two lower support rods.

[0009] The technical effect of adopting the above further solution is: the linkage block transfers the pressure to the lower support rod through the lower fixed plate, and the lower support rod slides inside the movable groove through the slider to disperse the vibration pressure.

[0010] As a preferred embodiment, it also includes a base, the outer surface of the base is provided with two movable grooves, multiple sliders are movable inside the two movable grooves, buffer strips are fixedly installed on both sides of the inner walls of the two movable grooves, one side of the multiple sliders is movably installed with a movable bar, the bottoms of the two movable grooves are fixedly connected to two slide rails, and the bottoms of the multiple sliders slide on the tops of the multiple slide rails.

[0011] The technical effect of adopting the above further solution is that while the slider slides through the bottom and the slide rail, the movable bar performs collision and buffering on the buffer bar during the sliding of the slider, thereby reducing the sliding speed.

[0012] As a preferred embodiment, a fixed block is fixedly installed on the top of the base, two springs 2 are fixedly installed on both sides of the fixed block, the other sides of the two springs 2 are fixedly installed on the outer surfaces of the two lower support rods, a telescopic column is fixedly installed on the top of the fixed block, a buffer spring is sleeved on the outer surface of the telescopic column, a vertical column is fixedly installed on the top of the linkage block, a connecting column is fixedly installed on the bottom of the base, and a screw is embedded on the outer surface of the connecting column.

[0013] The technical effect of adopting the above further solution is: the fixed block is used to pull the lower support rod through the second spring when the slider slides, the telescopic column is used to directly face the downward pressure of the linkage block and buffer it through the buffer spring, and the screws are used for installation on other equipment.

[0014] Compared with the prior art, the advantages and positive effects of the present invention are:

[0015] 1. When the utility model is in use, when a large external vibration is transmitted, the spring on the inner wall of the protective shell directly resists the shaking density meter body, and then transmits the vibration pressure downward through the support block and the upper support rod, and transmits it to the lower fixed plate through the upper fixed plate and the linkage block. The lower fixed plate transmits the pressure to the slider through the lower support rod. At this time, the slider slides inside the movable groove and slides through the slide rail. The movable bar on one side of the slider collides with the buffer bar when sliding, thereby buffering the pressure transmitted from the slider.

[0016] 2. In the utility model, while the slider slides, the fixed block applies a pulling force to the lower support rod through the second spring. The buffer spring directly buffers the linkage block from the front to stretch the telescopic column inside. When the vibration ends, all the forces rebound to restore to the previous state, solving the problem that the density meter may explode when encountering greater external vibration. Even if the anti-seismic function is strengthened from the inside, it is still useless, which causes great trouble to technicians and maintenance personnel. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figures 1 to 4 The utility model provides a technical solution: a seismic density meter, comprising: a density meter body 1, characterized in that: a plurality of springs 101 are fixedly installed on the outer surface of the density meter body 1, a protective shell 102 is fixedly installed on the other side of the plurality of springs 101, two connecting blocks 103 are fixedly installed on both sides of the protective shell 102, and two supporting blocks 104 are fixedly installed on one side of the two connecting blocks 103, and the plurality of supporting blocks 104 are evenly divided into two groups. An upper support rod 105 is fixedly installed inside each group of support blocks 104, and two upper fixing plates 106 are fixedly installed on the bottom of the two upper fixing plates 106, and a linkage block 107 is fixedly installed on the bottom of the plurality of upper fixing plates 106. The spring 101 on the inner wall of the protective shell 102 directly resists the shaking of the density meter body 1, and the pressure exerted on the protective shell 102 is transmitted to the upper support rod 105 and the upper fixing plate 106 through the provision of the connecting block 103 and then transmitted to the linkage block 107.

[0025] like Figures 1 to 4 As shown, a plurality of lower fixed plates 108 are fixedly installed at the bottom of the linkage block 107, and the plurality of lower fixed plates 108 are evenly divided into two groups. The bottom of each group of lower fixed plates 108 is fixedly connected with a lower support rod 109, and two sliders 110 are fixedly installed on both sides of the two lower support rods 109. The linkage block 107 transfers the pressure to the lower support rod 109 through the lower fixed plate 108, and the lower support rod 109 slides inside the movable groove 114 through the slider 110 to disperse the vibration pressure.

[0026] like Figures 1 to 4As shown, it also includes a base 2, and two movable grooves 114 are provided on the outer surface of the base 2. A plurality of sliders 110 are movable inside the two movable grooves 114. Buffer bars 112 are fixedly installed on both sides of the inner walls of the two movable grooves 114. A movable bar 111 is movably installed on one side of the plurality of sliders 110. The bottoms of the two movable grooves 114 are fixedly connected to two slide rails 113. The bottoms of the plurality of sliders 110 slide on the tops of the plurality of slide rails 113. When the sliders 110 slide with the slide rails 113 through the bottom, the movable bars 111 perform collision buffering on the buffer bars 112 during the sliding of the sliders 110, thereby reducing the sliding speed.

[0027] Working principle: This device is a shock-resistant density meter. When in use, when a large external vibration is transmitted, the spring 101 on the inner wall of the protective shell 102 directly resists the shaking density meter body 1, and then transmits the vibration pressure downward through the support block 104 and the upper support rod 105, and transmits it to the lower fixed plate 108 through the upper fixed plate 106 and the linkage block 107. The lower fixed plate 108 transmits the pressure to the slider 110 through the lower support rod 109. The slider 110 slides inside the movable groove 114 at this time and slides through the slide rail 113. The movable bar on one side of the slider 110 When sliding, 111 collides with the buffer bar 112 to buffer the pressure transmitted from the slider 110. While the slider 110 slides, the fixed block 201 applies a pulling force to the lower support rod 109 through the spring 202. The buffer spring 204 directly buffers the linkage block 107 from the front to stretch the telescopic column 203 inside. When the vibration ends, all the forces rebound and return to their previous state, solving the problem that the density meter may explode when encountering greater external vibrations. Even if the anti-seismic function is strengthened from the inside, it is of no avail, which causes great trouble to technicians and maintenance personnel.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
