Deformation, free end produce displacement, by means of transmission mechanism, drive pointer to indicate temperature value on dial.
It when thermometer is installed, should ensure that thermometer is connected firmly, while make dial side oriented manipulation personnel again, just
In observation.Since ordinary temp table is male thread connection mode, in order to meet above-mentioned two condition, at present generally using
Jointing temp table lower part in positive and negative female adapter, under connect the connection mode of extension pipe, so that associated components are all fixed to be connected
It is connected together, so that needing to disassemble repeatedly when adjusting temperature apparent bearing to adjust repeatedly can just be adjusted to target direction, takes
When it is laborious.
The content of the invention
In order to overcome the above-mentioned deficiency of the prior art, the utility model provides a kind of thermometer with universal joint.
The technical scheme in the invention for solving the technical problem is：A kind of thermometer with universal joint, including table
Shell, hollow table handle and lid are located at glass cover on the watchcase, are equipped with dial plate in the watchcase, on the dial plate
Equipped with pointer, temperature-sensing element is equipped with the table handle, which is located at the end of the table handle, and the watchcase passes through one
Universal joint is connected with the table handle, and corner spring is equipped with the universal joint, capillary is equipped with the table handle,
One end of the capillary is connected with the temperature-sensing element, and the other end of the capillary and the lower end of the corner spring connect
Connect, the upper end of the corner spring is equipped with transmission shaft, and the transmission shaft is connected with the pointer.
Further, the universal joint includes mounting, universal lower contact and universal adjustable top connection, in the mounting
Equipped with bellows.
Further, the mounting is affixed by the universal lower contact and the table handle, and the mounting passes through
The universal adjustable top connection and the watchcase are affixed.
Further, the watchcase is equipped with bearing, the transmission shaft through the bearing and with the pointer
Connection.
Further, the mounting includes upper and lower part, and the top passes through one side plate and the lower hinge.
Further, sealing ring is equipped between the glass cover and the watchcase, the sealing ring offers sealing
Groove, the outer edge of the glass cover are embedded in the seal groove.
The beneficial effects of the utility model are：Traditional male thread connection mode is replaced using universal joint so that temperature
Table connection is more firm, using reliable, adjusts that direction is more convenient, and staff is more easy to observed data.
Brief description of the drawings
Fig. 1 is the sectional view of the utility model.
Fig. 2 is the structure diagram of universal joint.
Fig. 3 is another structure diagram of universal joint.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
With reference to Fig. 1~Fig. 3, a kind of thermometer with universal joint, including watchcase 1, hollow table handle 2 and lid are set
Glass cover 3 on the watchcase 1, the watchcase 1 is interior to be equipped with dial plate 4, and the dial plate 4 is equipped with pointer 5, the table handle
Be equipped with temperature-sensing element 6 in 2, which is located at the end of the table handle 2, the watchcase 1 by a universal joint 7 and
The table handle 2 connects, and corner spring 8 is equipped with the universal joint 7, capillary 9 is equipped with the table handle 2, described
One end of capillary 9 is connected with the temperature-sensing element 6, and the other end of the capillary 9 and the lower end of the corner spring 8 connect
Connect, the upper end of the corner spring 8 is equipped with transmission shaft 10, and the transmission shaft 10 is connected with the pointer 5.
In the present embodiment, the universal joint 7 includes mounting 11, universal lower contact 12 and universal adjustable top connection 13,
Bellows 14 is equipped with the mounting 11.Preferably, the mounting 11 includes top 15 and lower part 16, the top 15
It is hinged by one side plate 17 and the lower part 16.The structure of the universal joint 7 make it that it is more flexibly square when adjusting direction
Just.
In the present embodiment, the mounting 11 is affixed by the universal lower contact 12 and the table handle 2, described
Mounting 11 is affixed by the universal adjustable top connection 13 and the watchcase 1.Pass through special universal lower contact 12 and ten thousand
