Detailed description of the invention
Upon reading the detailed description of non-limiting embodiments with reference to the following drawings, other spies of the utility model
Sign, objects and advantages will become more apparent upon：
Fig. 1 is the utility model Structure explosion diagram.
It is shown in figure：
Specific embodiment
The utility model is described in detail combined with specific embodiments below.Following embodiment will be helpful to this field
Technical staff further understands the utility model, but does not limit the utility model in any form.It should be pointed out that ability
For the those of ordinary skill in domain, without departing from the concept of the premise utility, various modifications and improvements can be made.
These are all within the protection scope of the present invention.
In the description of the present invention, it should be understood that term " on ", "lower", "front", "rear", "left", "right",
The orientation or positional relationship of the instructions such as "vertical", "horizontal", "top", "bottom", "inner", "outside" be orientation based on the figure or
Positional relationship is merely for convenience of describing the present invention and simplifying the description, rather than the device or member of indication or suggestion meaning
Part must have a particular orientation, be constructed and operated in a specific orientation, therefore should not be understood as limiting the present invention.
Portable mattress hardness-testing device provided by the utility model, it is described comprising bracket, counterweight and rangefinder 5
Rangefinder 5 is relatively fixed with bracket on length extending direction.One or more counterweights are removably mounted on bracket, described
Bracket includes guide part, and the counterweight is mounted on guide part by following any or various ways：Nested encryptions；Spiral shell
Line connection；Hook together connection；It is connected together.In embodiment by the way of nested encryptions, it is easier to accomplish to prevent integrally-built
The inaccuracy of measurement structure caused by deviating.For being threadedly coupled, have the shortcomings that counterweight disassembly is inconvenient；For the company of hooking together
It connects, i.e., counterweight is added in the form of hook, being easy to appear shaking or circumferential discontinuity leads to inclined defect；It is right
It in being connected together, is directly clamped among on guide part for example, by using card slot, being also easy to appear all upward pressures and being unevenly distributed leads to bracket
The phenomenon that inclination.
As shown in Figure 1, the bracket also includes chassis 1 in embodiment, the guide part includes aluminum pipe 2, the counterweight
Comprising counterweight, positioning convex platform 11 is provided on the chassis 1, aluminum pipe 2 is removably mounted on positioning convex platform 11 by screw thread.Weight
It is provided with jack hole on code, counterweight is mounted on aluminum pipe 2 by jack hole nesting.Preferably, the counterweight also includes hanging ring
7, one or more lifting hole(eyelet)s 10 are provided on counterweight, and the hanging ring 7 is removably mounted in lifting hole(eyelet) 10.By 7 structure of hanging ring, make
Counterweight is obtained to be easier to be placed into or take out.In addition, the utility model can be furnished with the counterweight of different quality, in order to different beds
Pad product measures.
The cross-sectional shape of the jack hole and the cross-sectional shape of aluminum pipe 2 are identical or different, the cross-sectional shape of aluminum pipe 2
For following any shape：It is round；It is semicircle；Ellipse；Polygon.The cross-sectional shape of the counterweight be it is following any or
Appoint various shapes：It is round；It is semicircle；Ellipse；Polygon.In embodiment, round knot has been all made of using aluminum pipe 2 and counterweight
Structure, on the one hand, on the other hand being put into and taking out convenient for counterweight since circle has good symmetry, can prevent from putting
During entering counterweight, the deformation of mattress run-off the straight formula influences measurement result.In addition, the diameter of jack hole should be slightly bigger than aluminium
The outer diameter of pipe 2 prevents counterweight from excessive radial deflection occur with respect to 2 central axes of aluminum pipe, leads to the run-off the straight of bracket and influences
Measurement accuracy.
The aluminum pipe 2 is connected on the other end of one end with chassis 1 relatively along axial both ends and is equipped with rangefinder sheath
6, the rangefinder 5 is mounted in rangefinder sheath 6.Rangefinder sheath 6 is mounted in the axial aperture of aluminum pipe 2, the axial direction
