Description
Technical Field
The utility model relates to the field of mortise and tenon structures, in particular to a fixed positioning structure of a dovetail groove and a tenon.
Background
The mortise and tenon joint is an extremely exquisite utility model, and the member connection mode ensures that the traditional Chinese wood structure becomes a special flexible structure body which surpasses the prior-generation building bent frame, frame or steel frame, not only can bear larger load, but also allows certain deformation, and certain earthquake energy is counteracted by the deformation under the earthquake load, so that the earthquake response of the structure is reduced. The dovetail joint is a right-angle connection joint of the flat timber, and the trapezoidal tenon can enable the corner of the workpiece to be connected with high strength, so that the workpiece is prevented from being disconnected when being stressed. The mortise and tenon structure can provide the effect of location when connecting, and simple mortise and tenon structure is not hard up yet easily for the two parts that this mortise and tenon structure links to each other produce relative displacement.
Disclosure of Invention
In order to solve the technical problems, the utility model adopts the following technical scheme:
the fixed positioning structure of dovetail groove and tenon comprises tenon, mortise, positioning pin and locking sleeve, wherein a countersunk pin hole is formed in the middle position of the bottom of the mortise, the locking sleeve is arranged in the countersunk pin hole, a positioning ring is arranged at the end part of the locking sleeve, and the positioning ring is clamped in the countersunk pin hole;
the tenon bottom is opened has the pinhole, the locating pin install in the lock sleeve reaches in the pinhole.
Further, the locating pin and the locking sleeve are correspondingly provided with clamping steps.
Further, the clamping step is located outside the mortise.
Further, an axial adjusting seam is reserved at the outer end of the locking sleeve, a circumferential annular groove is formed in the outer side of the locking sleeve, the annular groove is located between the outer end of the locking groove and the clamping step, and an elastic fixing ring is sleeved in the annular groove.
The utility model has the beneficial effects that:
the structure can effectively ensure the position of the tenon in the mortise, prevent the tenon from loosening and enable the positioning to be more accurate;
the locating pin can be dismantled, the reuse of being convenient for.
Drawings
FIG. 1 is a schematic diagram of the structure of an embodiment 1 of the present utility model;
fig. 2 is a schematic structural diagram of embodiment 2 of the present utility model.
Reference numerals illustrate: the locking device comprises a tenon 1, a tenon groove 2, a locating pin 3, a clamping step 301, a locking sleeve 4, a locating ring 401 and an elastic fixing ring 5.
Detailed Description
The present utility model will be described in further detail with reference to the accompanying drawings.
Example 1
The fixed positioning structure of dovetail groove and tenon comprises a tenon 1, a tenon groove 2, a positioning pin 3 and a locking sleeve 4, wherein a countersunk pin hole is formed in the middle position of the bottom of the tenon groove 2, the locking sleeve 4 is arranged in the countersunk pin hole, a positioning ring 401 is arranged at the end part of the locking sleeve 4, and the positioning ring 401 is clamped in the countersunk pin hole;
the bottom of the tenon 1 is provided with a pin hole, and the locating pin 3 is arranged in the locking sleeve 4 and the pin hole. The locating pin 3 and the locking sleeve 4 are correspondingly provided with a clamping step 301. The clamping step 301 is located outside the mortise slot 2.
The working principle of the utility model is as follows: the locking sleeve 4 is in a straight cylindrical state initially, the inner diameter is equal to the diameter of the front end of the positioning pin 3, and no clamping step 301 exists; firstly, placing the locking sleeve 4 into a pin hole of the mortise 2, then installing the tenon 1 into the mortise 2, inserting a positioning pin into the pin hole, and finally clamping the locking sleeve 4 with a clamping step 301 of the positioning pin 3 by using a clamp to deform, so as to form a clamping step 301 structure shown in fig. 1, and further complete positioning of the positioning pin 3;
example 2
The fixed positioning structure of dovetail groove and tenon comprises a tenon 1, a tenon groove 2, a positioning pin 3 and a locking sleeve 4, wherein a countersunk pin hole is formed in the middle position of the bottom of the tenon groove 2, the locking sleeve 4 is arranged in the countersunk pin hole, a positioning ring 401 is arranged at the end part of the locking sleeve 4, and the positioning ring 401 is clamped in the countersunk pin hole;
the bottom of the tenon 1 is provided with a pin hole, and the locating pin 3 is arranged in the locking sleeve 4 and the pin hole. The locating pin 3 and the locking sleeve 4 are correspondingly provided with a clamping step 301. The clamping step 301 is located outside the mortise slot 2.
An axial adjusting seam is reserved at the outer end of the locking sleeve 4, a circumferential annular groove is formed in the outer side of the locking sleeve 4 and located between the outer end of the locking sleeve 4 and the clamping step 301, and an elastic fixing ring 5 is sleeved in the annular groove.
Firstly, placing the locking sleeve 4 into a pin hole of the mortise 2, then installing the tenon 1 in the mortise 2, and inserting a positioning pin into the pin hole; the circumferential annular groove is formed in the part, close to the outermost end, of the locking sleeve 4, and an axial adjusting slit is formed in the outer end of the locking sleeve 4, so that the opening degree of the locking sleeve 4 can be adjusted, and the locking sleeve is convenient to install and detach; an elastic fixing ring 5 is arranged in the locking sleeve 4 and used for fixing the locking sleeve 4 and preventing the locking sleeve 4 from loosening.
