Abstract

The utility model relates to a handheld sphygmomanometer which comprises a sphygmomanometer shell and a machine core shell, wherein the machine core shell is connected with a capsule machine core through threads and is fixed in the sphygmomanometer shell by a screw; a sphygmomanometer ring is arranged outside the machine core shell; the exterior of the sphygmomanometer shell is fixedly connected with an air valve by a buckling structure and is further connected with an inflation through the threads of a decoration ring; and the air valve and the inflation ball are connected with the capsule machine core by hoses. The sphygmomanometer has the advantages that the product cost is lowered, the properties of the product are ensured, and the production efficiency is improved.

Description

The hand-held sphygomanometers

Technical field:

This utility model belongs to medical apparatus and instruments, specifically a kind of novel hand-held sphygomanometers.

Background technology:

The hand-held sphygomanometers comprise inflatable ball, handle, air valve, watchcase, bellows movement, table circle, and are in existing hand-held sphygomanometers, as shown in Figure 3; Inflatable ball, handle, air valve, bellows movement and table circle all are fixed on the watchcase; Through the inflatable ball inflation, through pipeline, air pressure passes to the bellows movement; Shift the pointer running onto, the deficiency of this structure is: 1, the movement part requires very high to production and processing; 2. movement mechanism complicacy, so the production of product and processing cost are higher; 3, the structure of this movement makes the product calibration comparatively complicated, and production efficiency is low.

Summary of the invention:

The purpose of this utility model is in order to overcome above deficiency, provides a kind of and reduces product cost, guarantees performance of products, the hand-held sphygomanometers of enhancing productivity.

The purpose of this utility model realizes through following technical scheme: a kind of hand-held sphygomanometers; Comprise watchcase, machine core shell, through the bellows movement that has been threaded, machine core shell is fixed on watchcase through screw on the machine core shell; The outside of machine core shell is provided with the table circle; The outside of watchcase is fixedly connected with air valve through buckle structure, and also through the inflatable ball that has been threaded of case ring, air valve is connected with the bellows movement through flexible pipe respectively with inflatable ball in the outside of watchcase.

The further improvement of this utility model is: the bellows movement comprises train wheel bridge, lower plate; Be fixedly connected with two movement posts through screw between train wheel bridge and the lower plate; Being connected with respectively between train wheel bridge and the lower plate changes tooth axle and sheet tooth axle; Be provided with plate gear between sheet tooth axle and the lower plate, be connected with correcting plate and eccentric screw through screw on the plate gear, plate gear also is connected with the push rod that can freely rotate through screw; The bottom of push rod is provided with bellows, and bellows is fixed on the machine core shell through being threaded.

This utility model compared with prior art has the following advantages:

1, through the design of machine core shell, make the anti-external interference ability of product strengthen, strengthen properties of product;

2, the inverted mounting means of movement bellows makes product structure compact, more convenient to operate more;

3, the motion of movement makes product produce more easily, and performance is strengthened, and can reduce cost;

Description of drawings:

Fig. 1 is the structural representation of this utility model;

Fig. 2 is the structural representation of bellows movement;

Fig. 3 is the structural representation of existing hand-held sphygomanometers;

Label among the figure: 1-watchcase, 2-movement table, 3-bellows movement, 4-table circle, 5-air valve, 6-case ring, 7-inflatable ball, 8-train wheel bridge, 9-lower plate, 10-movement post, 11-change tooth axle, 12-sheet tooth axle, 13-plate gear, 14-correcting plate, 15-eccentric screw, 16-push rod, 17-bellows, 18-handle.

The specific embodiment:

In order to deepen understanding to this utility model, will combine embodiment and accompanying drawing that this utility model is done further to detail below, this embodiment only is used to explain this utility model, does not constitute the qualification to this utility model protection domain.

Show a kind of embodiment of this utility model hand-held sphygomanometers like Fig. 1, Fig. 2; Comprise watchcase 1, machine core shell 2, through the bellows movement 3 that has been threaded, machine core shell 2 is fixed on watchcase 1 through screw on the machine core shell 2; The outside of machine core shell 2 is provided with table circle 4; The outside of watchcase 1 is fixedly connected with air valve 5 through buckle structure, and also through the inflatable ball 7 that has been threaded of case ring 6, air valve 5 is connected with bellows movement 3 through flexible pipe respectively with inflatable ball 7 in the outside of watchcase 1; The distortion of watchcase 1 and vibration can not influence the variation of sphygomanometers indicating value, make the performance of sphygomanometers get a promotion.Bellows movement 3 adopts inverse manner to be installed in the watchcase 1 simultaneously, and this frame mode is conserve space better, makes that the design of entire product is compact, more convenient to operate more.

Bellows movement 3 comprises train wheel bridge 8, lower plate 9; Be fixedly connected with two movement posts 10 through screw between train wheel bridge 8 and the lower plate 9; Being connected with respectively between train wheel bridge 8 and the lower plate 9 changes tooth axle 11 and sheet tooth axle 12; Be provided with plate gear 13 between sheet tooth axle 12 and the lower plate 9, be connected with correcting plate 14 and eccentric screw 15 through screw on the plate gear 13, plate gear 13 also is connected with the push rod 16 that can freely rotate through screw; The bottom of push rod 16 is provided with bellows 17, and bellows 17 is fixed on the machine core shell 2 through being threaded.When bellows 17 inflations move upward; Promote push rod 16 and move upward, plate gear 13 rotates under the effect of push rod 16, and driving changes 11 rotations of tooth axle; Simultaneously can carry out calibration through the moment of regulating between push rod 16 and the plate gear 13 through regulating eccentric screw 15 calibration the time.Such structure makes calibration convenient, and better controls.

This utility model makes the anti-external interference ability of product strengthen through the design of machine core shell, strengthens properties of product; The inverted mounting means of movement bellows makes product structure compact, more convenient to operate more; The motion of movement makes product produce more easily, and performance is strengthened, and can reduce cost.
