Description of the Invention: [Technical Field] The present invention relates to a distance measuring device, and more particularly to an optical distance measuring device capable of reducing post-assembly deformation. — [Prior Art] Referring to Figures 1 and 2, a general optical distance measuring device 丨 mainly includes an optical core group 11, a circuit board 12 and a casing 13. The optical module 11 has a body 111, a first objective lens unit and a second objective lens unit 113 disposed along the first axis X1' and a second axis X2 at the end of the body m, along the first axis. a receiving unit 114 disposed at the other end of the main body (1), a unit u5 disposed at the other end of the main body U1 along the second axis, a display unit, the eyepiece unit 丨丨7, and the opposite The unit 11 $ is disposed at a transmitting unit 118 at the other end of the body 111. The display unit it 116 is a displayable image and a cross line (not shown) on the second axis X2. The emission unit U8 emits a light beam relative to the unit U5, and the light beam is projected to the object through the unit U5 and the second objective unit 113, and the reflected light beam is transmitted from the first objective unit 112. After entering the receiving unit 114, the measurement result is finally displayed at ° ° & 116, and the shape is - ranging system. In addition, the H-eyepiece unit U7 can cooperate with the display unit 116, the unit 115 and the second objective unit 113 to form a telephoto system. Referring to Figures 1 and 3, the circuit board 12 is locked to the body 111 side of the optical module n. Bu double 13 has an upper cover 丨 31 and a base 1254125 which are opposite to each other. The upper cover (3) and the front cover i33 of the base ～ are assembled as follows: the optical axis of the optical mode & u is adjusted The target of the cross-reference line of the display unit 116 is only coincident with the target hit by the nine-inch and the reflected light beam is located within the field of view of the receiving unit ιΐ4 towel-sensitive diode (APD). It is (4) Αρβ to the maximum reflected beam, which improves the measurement accuracy. 2. The circuit board 锁 is locked to the body (1) of the optical module n. 3. The optical module η is locked on the base 132 of the outer casing π. Finally, the upper cover (3) is covered by the upper cover 133 and the rear cover 134 to complete the assembly. However, since the optical module U, the circuit board 12, and the outer casing 13 are both hard materials, in the case where the optical module u has been adjusted in advance, the assembly mode will be The two actions cause the optical axis to be offset: thus affecting the accuracy of the measurement: - when the circuit board 12 is attached to the body 1U of the optical module 11, the circuit board that passes through the reflow oven will be generated A certain degree of deformation causes the body that is locked with the circuit board 12 to be affected to be deformed, causing a shift in the optical axis. The second is that when the body 111 of the optical module 11 is locked to the base 132 of the outer casing 13, the body of the optical unit 11 is required because the hole position is not completely aligned, and the locking itself requires a certain pressing force. 111 also produces deformation, which will cause the adjusted optical axis to shift. Therefore, in the assembly process, the movement of the optical axis must be repeated, which is time consuming and labor-intensive. And the outer cover 13 is formed by the upper cover 13 1 and the base 13 2 , and the plurality of components such as the front cover 133 and the rear cover 134 , so that a gap of 1254 288 is formed. The whole is not conducive to preventing the re-selection of the eve of the day ~ by the water, but must sigh the number of waterproof components in order to achieve the purpose of waterproofing. SUMMARY OF THE INVENTION In view of the above, the object of the present invention is to provide an optical distance measuring device which can be improved by measuring the fineness and measuring the fineness of the low-profile group. The invention can reduce the optical distance measuring device after the assembly, the circuit board and the outer casing. The lock attachment accessory has the money 4 and the (4) learning module - (four) knot. (4) the road board < is the disk «hai The lock (four) is consolidated and suspended from the other side of the optical module. The continuation is for the optical module and the circuit board to be accommodated, and is fixed with the lock accessory, so that the optical module and the circuit board are obtained.

The lock plate 31 is made of a material that is more plastic than ABS plastic, and has a number of perforations 311, a number of first through holes, a number of turns, and a hole 3 相对 relative to the screw hole 211 of the forest body 21 . 3. The spacers 32 pass through the gap of the optical module 2 and have a beak, and the locking screw holes 321 and 322 at the two ends have a first direction relative to the lock plate 3 1 . The number of holes 3 12 is the second through hole 41. The outer casing 5 has a casing 52 forming an opening 51, a front cover 53 closing the opening 52 of the casing 51, and a plurality of locks for positioning the screw hole 313 against the casing 52 with respect to the lock plate 3 Hole 54 (see Figure 9). The assembly steps of the preferred embodiment of the present invention are as follows: Referring to Figure 6, the optical module 2 is stacked on a top surface of the lock plate 31 and then passed through the perforations 3 11 of the lock plate 3 1 by the first bolts 33. After that, the screw module 211 of the main body 21 is screwed together, and the optical module 2 and the lock plate 31 are consolidated into one body. Then, the optical module 2 is adjusted by the optical axis 2254. In Fig. 7, with a number of 筮-w boards, the pens of the pens and the slabs 34 are respectively passed through the brothers' holes 3 12 of the lock plate 31, and squatted. , person" ^ the locking screw hole 321 of one end of the bolster 32 is screwed, so that the bolster 32 is erected on the top surface of the lock plate 31; then, the cymbal board 4 is placed at The pad % 2 is further smashed, and then a plurality of second bolts 34 are passed through the cymbal 4 of the circuit board 4, and then the locking snails of the other end of the pad 32 are respectively The hole 322 is screwed together. The circuit board 4 is integrated with the lock plate 31, and is suspended from a top surface of the optical module 2. Since the lock plate 31 has plasticity, the lock is During the solid process, the ▼, the ▼ and the road plate 4 have (4) 'the local area near the locking point of the lock plate 31' will also absorb most of the deformation, and the remaining part of the deformation. This small part Although the deformation of the lock plate 31 is slight, the optical module 2 is integrally fixed on the lock plate 31 and does not interfere with the circuit board 4, so that the optical module 2 as a whole The lock plate η: moves, there is almost no deformation or relative displacement between the main body and the internal units.
